Definitions

  • the invention relates to a handle of a stick provided with a strap.
  • Such sticks are, for example, used for sports such as downhill skiing, ski touring, cross-country skiing, snowshoeing, hiking or Nordic walking.
  • This type of stick has a handle equipped with a wrist strap allowing the user to improve the transmission of thrust force from hand to baton but also to release the handle without losing the stick or drop it.
  • a disadvantage related to the use of the wrist strap is the risk of injuries that can occur by wrist restraint. Indeed, in use, the stick can get caught involuntarily. In this case, the user's hand may be stuck in the wrist strap, which can injure the user by dislocation of the shoulder or wrist injury.
  • Ski poles having a strap attached to the handle removably, for which under the action of a determined solicitation, the strap is detached automatically so that no excessive stress can occur.
  • the strap can be detached from the handle as well under the effect of a traction directed laterally to the handle as under the effect of a traction directed in the extension of the handle.
  • the document FR-A-2 792 539 discloses a ski pole handle whose strap comprises an insert snapped into the upper part of the handle so as to trigger only under the effect of a traction directed in the extension of the handle.
  • the insert is thus put in place by deforming an element of the stick, in this case a part of the body of the handle.
  • These deformable elements are fragile and can break.
  • the disengagement of the strap requires the elastic deformation of the body of the handle. There is therefore a risk of deterioration of this expensive piece of expensive.
  • the proposed solutions describe an insert of complex shape to achieve, uneconomical and can be fragile.
  • EP-A-1 474 212 discloses a cross-country ski pole handle whose strap includes an insert snap-fastened in the upper part of the handle. This strap is, however, declipable only by a manual action on a locking lever. This solution does not provide triggering under the effect of a pull on the strap in the extension of the handle.
  • An object of the present invention is therefore to provide an improved stick handle.
  • One goal is notably to improve the safety of use of the stick, in particular to limit the risk of injury, by allowing the separation of the strap, only when it is requested in a specific direction.
  • Another goal is to avoid any inadvertent triggering of the strap.
  • Another goal is to have a simple, robust and compact handle.
  • the stick handle comprises a wrist strap formed of an insert strap, a body oriented along a longitudinal axis, the body having an insert housing for receiving the insert, the insert housing being provided in the upper part of the body so that the insert can be introduced into the housing in a direction substantially parallel to the longitudinal axis of the housing; body, a locking mechanism comprising a latch adapted to cooperate with the insert so as to maintain the insert in the insert housing, the unlocking of the locking mechanism being able to be actuated directly by a displacement of the insert in the direction inverse to the introduction of the insert.
  • the latch of the handle slides in a transverse housing (26) of the body.
  • the strap is fixed and kept locked to the body of the handle.
  • the locking mechanism keeps the insert secured to the strap.
  • the forces exerted laterally on the strap by the user do not trigger the mechanism.
  • the strap remains attached to the body. It is the same, when the user exerts a thrust force resulting in a downward effort, towards the tip of the stick. In this case, the pushing force is transmitted from the hand to the strap, then from the strap to the body. It is therefore important that the strap remains attached to the body during this propulsion phase.
  • the locking mechanism allows the disengagement of the strap.
  • Excessive axial traction is exerted, for example, when the tip of the stick remains stuck under the scree of an avalanche or in the roots of a tree while the skier is moving.
  • the stick can serve as an anchor and draw down the skier. It is therefore vital to break free from the stick.
  • the locking mechanism is simple and compact, it integrates perfectly with the handle and is robust. It does not present deformable snap-fastenable parts that can break and does not solicit deformation of the body. Maintenance is easy because the elements of the locking mechanism are easily interchangeable.
  • the invention also relates to a stick equipped with a handle as defined above.
  • an orthonormal coordinate system XYZ is used for which the transverse directions X and lateral Y are perpendicular to each other and perpendicular to the longitudinal direction Z of the stick.
  • the transverse direction X is oriented from the rear to the front of the stick.
  • the “bottom” or “bottom” side corresponds to the side of the stick tip as opposed to the “top” or “top” side corresponding to the side of the handle of the stick handle.
  • the “front” or “anterior” part refers to the part referring to the forward direction of the user opposed to the "rear” or “posterior” part. Also referred to as “vertical”, the longitudinal direction Z and “horizontal”, a direction perpendicular to the longitudinal direction Z.
  • FIGS. 1 to 5 represent a first embodiment of a handle 1 stick, for the practice including cross-country skiing, downhill skiing, ski touring, "free ride”, snowshoeing or Nordic walking.
  • the handle 1 comprises a body 2 and a strap 3.
  • the body 2 conventionally comprises a hollow internal space 21, generally cylindrical opening into the lower part of the body 2.
  • the hollow internal space 21 is shaped to receive a longitudinal rod of the stick, the latter generally ending with a tip having a tip and possibly a washer.
  • the axis of the cylindrical hollow space 21 defines the longitudinal direction Z1 of the handle 1.
  • the body 2 comprises a gripping portion 22 to be grasped by the user and may include a succession of reliefs and recesses distributed longitudinally to guide the fingers and the palm of the hand of the user.
  • the upper end 24 of the body 2 may have a pommel shape, substantially curved, adapted for the support of the palm of the hand of the user, especially during climbing phases.
  • the strap 3 comprises a strap 31 and an insert 32 that can be removably attached in an insert housing 25 of the body 2.
  • the insert housing 25 is formed on the body 2 so that the opening of the housing of insert 25 opens into the upper end 24.
  • the insert 32 can be introduced or removed from the insert housing 25 in an axial direction, that is to say in a direction substantially parallel to the longitudinal axis Z1 of the handle 1.
  • the insert housing 25 has, for example, a flared shape widening towards the upper opening.
  • the insert housing 25 is defined by a front face 251 and a rear face 252, limiting the housing in the direction X.
  • the front faces 251 and 252 rear are not vertical but forms an angle between them, preferably greater than 15 °.
  • the insert 32 is also defined by a front wall 321 and a rear wall 322.
  • the front walls 321 and 322 are not “vertical” but form between them an angle substantially the same as the angle between the front faces. 251 and rear 252.
  • the rear face 252 of the housing is vis-à-vis the rear wall 322 of the insert.
  • the rear face and the rear wall cooperate with each other.
  • the Figures 3 to 5 illustrate this construction faces 251, 252 and walls 321, 322 inclined "V" and complementary.
  • flared shape may be envisaged such as pyramidal, prismatic or frustoconical shapes.
  • the engagement of the insert 32 in the insert housing 25 is thus facilitated by the co-operating guidance of shapes between the flared shape of the insert housing 25 and the complementary shaped walls of the insert 32.
  • the strap 3 may further comprise a hinge shaft 33 connecting the strap 31 to the insert 32.
  • the insert 32 has a clearance 323 in its upper part forming a rear opening 3231 and an upper opening 3232.
  • This clearance 323 is delimited laterally by two side walls 3233, spaced a distance slightly greater than the width of the strap 31.
  • Each of the side walls is pierced by a through hole 320.
  • the two through holes 320 are aligned in a direction substantially parallel to the Y direction, when the insert 32 is mounted in the body 2.
  • Each through hole 320 is intended to receive one end of the hinge shaft 33.
  • the hinge shaft is mounted clamping in these through holes.
  • a portion of the strap 31 closely surrounds the hinge shaft 33, the hinge shaft 33 extending in the width of the strap 31.
  • the hinge shaft 33 is housed in a loop 311 of the strap 31, without tightening, so that the loop can freely rotate around the hinge shaft.
  • the length of the hinge shaft 33 is slightly greater than the width of the strap 31 so that the ends of the hinge shaft 33 protrude from the loop.
  • the strap 31 forms a second loop 312 consecutive to the first loop 311 for the passage of the hand of the user.
  • This construction allows the rotation of the strap 31 around the transverse hinge shaft 33, that is to say, an axis parallel to the Y direction when the insert 32 is mounted in the body 2.
  • the clearance 323 is dimensioned to allow the pivoting of the strap 31 around the hinge shaft 33 at an angle of at least 90 °.
  • the strap can tilt from a horizontal configuration, for which the strap extends substantially horizontally towards the rear ( figure 3 ), towards a vertical position, for which the strap extends substantially vertically upwards ( figures 4 and 5 ), Or vice versa.
  • the body 2 comprises a rear recess 28 communicating with the housing.
  • the rear recess 28 is dimensioned so that when the insert 32 is retained in the body 2, the rear opening 3231 of the insert 32 and the rear recess 28 are aligned, thereby creating an open recess to the back of the body for the housing of the strap.
  • This makes it possible to allow the strap 31 to tilt between the horizontal configuration ( figure 3 ) and the vertical configuration ( figures 4 and 5 ). Consequently, the strap 3 can pivot freely relative to the body at an angle of at least 90 ° between the horizontal configuration and the vertical configuration, tending the use of the stick 1 flexible and comfortable.
  • the orientation of the strap is such that its width is always oriented in a Y direction.
  • This specificity allows to have a recess 28 bit deep in the body 2 with respect to a strap whose orientation of the strap would be such that its width always remains oriented in a direction X or Z. Therefore, the strength of the handle is reinforced.
  • the force is transmitted to the body by the strap, at the level of the lower part of the rear clearance 28 and the lower part of the rear opening 3231 of the insert 32.
  • This construction provides a large bearing surface between the strap 31 and the body 2.
  • the strap therefore presses the entire width of the strap or at least over a large part of the width of the strap and over a length adding the bearing surface of the lower part of the rear clearance 28 and the bearing surface of the lower part of the posterior opening 3231.
  • the pushing force is therefore not only transmitted by the insert 32 but also by the strap 31 at this contact area.
  • the insert and the body are therefore less stressed which allows a better distribution of the thrust forces.
  • the strap 3, thus arranged, is compact and is completely integrated in the head of the upper end 24 of the body in a horizontal configuration ( figure 3 ).
  • the strap can be assembled differently to the insert.
  • the hinge shaft can pass through a hole perforating the width of the strap.
  • the upper surface 325 of the closing insert 32 has a shape in continuity with the upper end 24 of the body 2 when the insert 32 is retained in the body 2.
  • the top 325 has for example a rounded and curved shape.
  • the upper end of the handle 1 thus retains a generally ergonomic convex shape facilitating the grip by the palm of the hand of the user.
  • the user can push on the pommel of the stick without felt a localized pressure on his hand. Indeed, the thrust force exerted by the palm is distributed over a large area which reduces localized stress peaks.
  • the strap therefore consists of three simple pieces, economical and easy to achieve: the strap 31, the insert 32 and the hinge shaft 33.
  • the insert 32 does not include any deformable part which makes it robust.
  • the handle 1 further comprises a locking mechanism 10 comprising a latch 4 movable transversely between a projecting position, corresponding to the locking position, and a retracted position.
  • the lock 4 has for example the shape of a pin whose one end, the lock head 41, has a substantially hemispherical rounded shape.
  • the latch 4 is placed in a transverse housing 26 of the handle body 2, oriented in a direction parallel to the direction X.
  • the head of the latch 41 points towards the rear of the body 2.
  • the transverse housing 26 has for example a cylindrical shape having a diameter slightly greater than the diameter of the lock which allows the lock to slide freely in the transverse housing. In this example, the transverse housing 26 is centered horizontally and therefore passes through the body against the back 2.

  • the head of the lock 4.1 protrudes from the front face 251 of the insert housing 25, through the first orifice 261.
  • the insert 32 comprises a transverse recess 324 formed in the front wall 321 cooperating with the front face 251 of the insert housing 25.

  • the locking mechanism 10 also comprises, in this example, a retaining pin 6 intended to cooperate with a cavity 42 formed in the latch 4.
  • This cooperation allows the transverse displacement of the latch 4, that is to say, according to a direction parallel to the X direction, to a determined transverse position, the locking position, in one direction.

  • the cavity 42 extends in the transverse direction, parallel to the X direction, to block the transverse displacement of the latch 4.
  • the transverse length of the cavity 42 defines the maximum displacement path between the retracted position and the protruding position.

This ensures the position of the latch head 41 locking position, which is important to ensure the effective cooperation between the latch 4 and the transverse recess 324 of the insert. Furthermore, the portion of the latch projecting from the front face 251 of the insert housing 25 contributes to the determination of the engagement and triggering force of the strap.
  • the portion of the latch projecting from the front face 251 has, when the latch is in the locked position, an inclination with respect to a horizontal plane XY. Indeed, when axially pulling on the insert, the lower edge of the transverse recess 324 comes into contact with the lock head 41.

  • the lock head 41 may be different, for example, in the form of a pyramid, a cone. What is important is that the latch head 41 has a well oriented slope inclined at an angle to a horizontal plane.
  • the engagement and triggering force of the strap is mainly determined by the resilient means 5 for returning the latch 4 in the locking position. It is therefore advantageous to be able to adjust the force exerted on the latch 4 by this elastic means 5.
  • the locking mechanism 10 may thus comprise means for adjusting the triggering threshold, that is to say, for adjusting the force exerted by the elastic means on the lock, in particular when the lock is in the locking position.
  • This adjustment means can be arranged in the transverse housing 26 receiving the latch 4.
  • the transverse housing 26 which receives the latch 4 is through. It opens, on the one hand, in the insert housing 25, via a first orifice 261, as we have seen previously, and on the other hand, on the outside, at the front of the body 2, via a second orifice 262.
  • An adjustment screw 7 is then screwed into the internal threaded portion 263 in order to seal the transverse housing 26.
  • the spring 5 is interposed between the adjusting screw 7 and the latch 4. One end of the spring 5 is in contact with the adjusting screw 7 and a second end of the spring 5 is in contact with the latch 4. This arrangement makes it possible to more or less force the spring 5 against the latch 4 according to the transverse position of the adjusting screw 7. To modify the threshold triggering the locking mechanism, that is to say the force with which the strap 3 is retained by the latch 4, it is sufficient to screw or unscrew the adjusting screw 7.

  • Excessive axial traction Fa may be exerted for example because the tip of the stick 1 has remained stuck for example under the scree of an avalanche or in the roots of a tree. In this case, the stick starts to pull too hard on the wrist and thus on the user's arm with a significant axial component, in particular because of the speed of the user compared to the stopping of the stick.

  • This displacement of the latch 4 compresses the spring 5. Consequently, to obtain the displacement of the desired latch, that is to say, a displacement allowing the latch 4 to no longer cooperate with the transverse recess 324 of the insert 32, it is necessary to exercise a determined effort on the lock.

L'invention concerne une poignée de bâton munie d'une dragonne. De tels bâtons sont, par exemple, utilisés pour des sports tels que le ski alpin, le ski de randonnée, le ski de fond, la marche en raquettes à neige, la randonnée ou la marche nordique.The invention relates to a handle of a stick provided with a strap. Such sticks are, for example, used for sports such as downhill skiing, ski touring, cross-country skiing, snowshoeing, hiking or Nordic walking.

Ce type de bâton comporte une poignée équipée d'une dragonne permettant à l'utilisateur d'améliorer la transmission d'effort de poussée de la main au bâton mais également de lâcher la poignée sans perdre le bâton ou le laisser tomber. Un inconvénient lié à l'usage de la dragonne est le risque de blessures pouvant survenir par entrave du poignet. En effet, en usage, le bâton peut se coincer involontairement. Dans ce cas, la main de l'utilisateur peut rester bloquée dans la dragonne, ce qui peut blesser l'utilisateur par luxation d'épaule ou lésion du poignet.This type of stick has a handle equipped with a wrist strap allowing the user to improve the transmission of thrust force from hand to baton but also to release the handle without losing the stick or drop it. A disadvantage related to the use of the wrist strap is the risk of injuries that can occur by wrist restraint. Indeed, in use, the stick can get caught involuntarily. In this case, the user's hand may be stuck in the wrist strap, which can injure the user by dislocation of the shoulder or wrist injury.

On connaît des bâtons de ski comportant une dragonne fixée à la poignée de manière amovible, pour lesquels sous l'action d'une sollicitation déterminée, la dragonne se détache automatiquement si bien qu'aucune sollicitation excessive ne peut se produire. La dragonne peut se détacher de la poignée aussi bien sous l'effet d'une traction dirigée latéralement à la poignée que sous l'effet d'une traction dirigée dans le prolongement de la poignée.Ski poles are known having a strap attached to the handle removably, for which under the action of a determined solicitation, the strap is detached automatically so that no excessive stress can occur. The strap can be detached from the handle as well under the effect of a traction directed laterally to the handle as under the effect of a traction directed in the extension of the handle.

On constate cependant des déclenchements intempestifs de la dragonne pour ce type de poignée car le détachement de la dragonne sous l'effet d'une traction latérale à la poignée peut s'avérer inutile, voire indésirable.There is, however, inadvertent triggering of the strap for this type of handle because the detachment of the strap under the effect of a lateral traction to the handle may be unnecessary or undesirable.

DE4005193A1 et DE2417959 , décrivent une poignée de bâton de ski équipée d'une dragonne de sécurité munie d'une pièce de liaison fixée par encliquetage dans un logement de la poignée. DE4005193A1 and DE2417959 , describe a ski pole handle equipped with a safety strap provided with a connecting piece fixed by snapping into a housing of the handle.

Le document FR-A-2 792 539 décrit une poignée de bâton de ski dont la dragonne comprend un insert fixé par encliquetage dans la partie supérieure de la poignée de manière à se déclencher uniquement sous l'effet d'une traction dirigée dans le prolongement de la poignée. L'insert est ainsi mis en place en déformant un élément du bâton, en l'occurrence une partie du corps de la poignée. Ces éléments déformables sont fragiles et peuvent se casser. De plus, le désencliquetage de la dragonne nécessite la déformation élastique du corps de la poignée. Il existe donc un risque de détérioration de cette pièce massive coûteuse. Enfin, les solutions proposées décrivent un insert de forme complexe à réaliser, peu économique et pouvant être fragile.The document FR-A-2 792 539 discloses a ski pole handle whose strap comprises an insert snapped into the upper part of the handle so as to trigger only under the effect of a traction directed in the extension of the handle. The insert is thus put in place by deforming an element of the stick, in this case a part of the body of the handle. These deformable elements are fragile and can break. In addition, the disengagement of the strap requires the elastic deformation of the body of the handle. There is therefore a risk of deterioration of this expensive piece of expensive. Finally, the proposed solutions describe an insert of complex shape to achieve, uneconomical and can be fragile.

Le document EP-A-1 474 212 décrit une poignée de bâton de ski de fond dont la dragonne comprend un insert fixé par encliquetage dans la partie supérieure de la poignée de manière. Cette dragonne est cependant déclippable uniquement par une action manuelle sur un levier de verrouillage. Cette solution ne propose pas de déclenchement sous l'effet d'une traction sur la dragonne dans le prolongement de la poignée.The document EP-A-1 474 212 discloses a cross-country ski pole handle whose strap includes an insert snap-fastened in the upper part of the handle. This strap is, however, declipable only by a manual action on a locking lever. This solution does not provide triggering under the effect of a pull on the strap in the extension of the handle.

Un but de la présente invention est donc de proposer une poignée de bâton améliorée.An object of the present invention is therefore to provide an improved stick handle.

Un but est notamment d'améliorer la sécurité d'utilisation du bâton, notamment de limiter le risque de blessure, en permettant la désolidarisation de la dragonne, uniquement lorsqu'elle est sollicitée selon une direction spécifique.One goal is notably to improve the safety of use of the stick, in particular to limit the risk of injury, by allowing the separation of the strap, only when it is requested in a specific direction.

Un autre but est d'éviter tout déclenchement intempestif de la dragonne.Another goal is to avoid any inadvertent triggering of the strap.

Un autre but est d'avoir une poignée simple, robuste et compacte.Another goal is to have a simple, robust and compact handle.

L'objet de la présente invention est défini par la revendication 1. La poignée de bâton comprend une dragonne formée d'une sangle teliée à un insert, un corps orienté selon un axe longitudinal, le corps comportant un logement d'insert destiné à recevoir l'insert, le logement d'insert étant ménagé dans la partie supérieure du corps de sorte que l'insert puisse s'introduire dans le logement selon une direction sensiblement parallèle à l'axe longitudinal du corps, un mécanisme de verrouillage comprenant un verrou apte à coopérer avec l'insert de manière à maintenir l'insert dans le logement d'insert, le déverrouillage du mécanisme de verrouillage pouvant être actionné directement par un déplacement de l'insert selon la direction inverse à l'introduction de l'insert.The object of the present invention is defined by claim 1. The stick handle comprises a wrist strap formed of an insert strap, a body oriented along a longitudinal axis, the body having an insert housing for receiving the insert, the insert housing being provided in the upper part of the body so that the insert can be introduced into the housing in a direction substantially parallel to the longitudinal axis of the housing; body, a locking mechanism comprising a latch adapted to cooperate with the insert so as to maintain the insert in the insert housing, the unlocking of the locking mechanism being able to be actuated directly by a displacement of the insert in the direction inverse to the introduction of the insert.

Le verrou de la poignée coulisse dans un logement transversal (26) du corps.The latch of the handle slides in a transverse housing (26) of the body.

Ainsi en utilisation normale par l'utilisateur, la dragonne est fixée et maintenue verrouillée au corps de la poignée. Le mécanisme de verrouillage permet de maintenir l'insert solidaire de la sangle.Thus in normal use by the user, the strap is fixed and kept locked to the body of the handle. The locking mechanism keeps the insert secured to the strap.

Avec le dispositif selon l'invention, les efforts exercés latéralement sur la dragonne par l'utilisateur ne déclenchent pas le mécanisme. La dragonne reste solidaire du corps. Il en est de même, lorsque l'utilisateur exerce un effort de poussée se traduisant par un effort vers le bas, en direction de la pointe du bâton. Dans ce cas, l'effort de poussée est transmis de la main à la sangle, puis de la dragonne au corps. Il est donc important que la dragonne reste fixée sur le corps lors de cette phase de propulsion.With the device according to the invention, the forces exerted laterally on the strap by the user do not trigger the mechanism. The strap remains attached to the body. It is the same, when the user exerts a thrust force resulting in a downward effort, towards the tip of the stick. In this case, the pushing force is transmitted from the hand to the strap, then from the strap to the body. It is therefore important that the strap remains attached to the body during this propulsion phase.

En revanche, si l'utilisateur exerce une traction axiale excessive sur la sangle, c'est-à-dire, un effort vers le haut tendant à éloigner la dragonne du bâton, alors le mécanisme de verrouillage permet le désengagement de la dragonne. Une traction axiale excessive est exercée, par exemple, lorsque la pointe du bâton reste coincée sous les éboulis d'une avalanche ou dans les racines d'un arbre alors que le skieur est en mouvement. Dans le cas d'une avalanche, le bâton peut faire office d'ancre et attirer vers le bas le skieur. Il est alors vital de se libérer du bâton.On the other hand, if the user exerts excessive axial traction on the strap, that is to say, an upward effort tending to move the strap away from the stick, then the locking mechanism allows the disengagement of the strap. Excessive axial traction is exerted, for example, when the tip of the stick remains stuck under the scree of an avalanche or in the roots of a tree while the skier is moving. In the case of an avalanche, the stick can serve as an anchor and draw down the skier. It is therefore vital to break free from the stick.

En conditions normales, les efforts exercés sur la sangle sont alors bien répartis sur le corps, via l'insert. Le corps participe ainsi à la reprise d'efforts.Under normal conditions, the forces exerted on the strap are then well distributed on the body, via the insert. The body thus participates in the recovery of efforts.

En outre, le mécanisme de verrouillage est simple et compact, il s'intègre parfaitement à la poignée et est robuste. Il ne présente pas de pièces déformables par encliquetage susceptibles de se rompre et ne sollicite pas la déformation du corps. La maintenance est aisée car les éléments du mécanisme de verrouillage sont facilement interchangeables.In addition, the locking mechanism is simple and compact, it integrates perfectly with the handle and is robust. It does not present deformable snap-fastenable parts that can break and does not solicit deformation of the body. Maintenance is easy because the elements of the locking mechanism are easily interchangeable.

Selon des aspects avantageux mais non obligatoires de l'invention, une telle poignée peut incorporer une ou plusieurs des caractéristiques suivantes, prises dans toute combinaison techniquement admissible :

  • Le verrou mobile se translate dans un trou transversal ménagé dans le corps, le trou transversal étant orienté selon un axe transversal sensiblement perpendiculaire à l'axe longitudinal du corps.
  • Le verrou est maintenu dans une position stable de verrouillage par un moyen élastique. Avantageusement, le mécanisme de verrouillage comprend un moyen de réglage de l'effort exercé par le moyen élastique sur le verrou lorsque le verrou est dans la position de verrouillage. Ainsi, on peut ajuster l'effort de déclenchement pour améliorer la sécurité ou éviter des déclenchements intempestifs.
  • Dans une configuration de verrouillage, une extrémité du verrou mobile fait saillie d'une face interne du logement de manière à venir se loger dans un évidement ménagé sur une paroi de l'insert en vis-à-vis, lorsque l'insert est placé dans le logement d'insert.
  • Le verrou présente la forme d'un pion.
  • Le mécanisme de verrouillage comprend une butée permettant de limiter le déplacement du verrou en direction du logement de l'insert. La butée permet de retenir la sortie du verrou et donc de maîtriser la partie émergeante de la tête de verrou, ce qui est important pour s'assurer de la force de verrouillage de l'insert par le verrou. Cela permet également de ne pas perdre le verrou en le maintenant toujours solidaire du corps de la poignée. Selon un mode de réalisation, la butée est une goupille de retenue coopérant avec une cavité ménagée dans le verrou.
  • Le logement d'insert présente une forme évasée s'élargissant vers l'ouverture supérieure et en ce que les parois de l'insert coopérant avec le logement d'insert sont inclinées et présentent une forme générale complémentaire, pour guider par coopération de forme l'engagement de l'insert dans le logement d'insert. L'engagement de l'insert dans le logement d'insert est ainsi aidé par le guidage par coopération de formes entre la forme évasée du logement d'insert et les parois inclinées de forme complémentaire de l'insert. L'enclenchement de la dragonne est donc rapide et facilité.
  • L'insert comprend un arbre d'articulation transversal reliant la sangle à l'insert de manière à permettre la rotation de la sangle autour d'un axe parallèle à la direction latérale quand l'insert est monté dans le corps. Avantageusement, l'insert comprend un dégagement dans lequel est logé l'arbre d'articulation transversal, le dégagement présentant une ouverture supérieure, débouchant sur une surface supérieure de l'insert, et une ouverture postérieure, s'étendant selon une direction transversale postérieure, lorsque l'insert est retenu dans le corps, le corps comportant un dégagement arrière alignée avec l'ouverture postérieure lorsque l'insert est retenu dans le corps, pour autoriser le pivotement latéral de la sangle entre une position verticale et une position horizontale. La dragonne peut donc pivoter librement par rapport au corps de poignée d'un angle d'au moins 90° entre la position axiale ou verticale et la position latérale ou horizontale, rendant l'utilisation du bâton souple et confortable. La sangle forme, par exemple, une première boucle entourant l'arbre d'articulation qui s'étend dans la largeur de la sangle et forme une deuxième boucle consécutive à la première boucle pour le passage de la main de l'utilisateur. Ainsi, lorsque l'utilisateur tient la poignée et que la sangle entoure son poignet, l'appui sur la sangle dirigé vers le bas se transmet sur le corps de la poignée par la sangle. Toute la largeur de la sangle participe ainsi à la reprise d'effort de poussée. En outre, la sangle est compacte et est complètement intégrée dans le pommeau en position latérale, ce qui améliore sa robustesse.
  • La surface supérieure de l'insert présente un contour supérieur en continuité avec une extrémité supérieure du corps de poignée lorsque l'insert est retenu dans le corps de poignée. L'extrémité supérieure du bâton peut ainsi conserver une forme générale ergonomique, plane ou bombée, facilitant la prise par la paume de la main du skieur en ascension, par exemple pour la pratique du free-ride ou du ski de randonnée.
According to advantageous but non-mandatory aspects of the invention, such a handle may incorporate one or more of the following features, taken in any technically permissible combination:
  • The movable lock is translated into a transverse hole in the body, the transverse hole being oriented along a transverse axis substantially perpendicular to the longitudinal axis of the body.
  • The latch is held in a stable locking position by resilient means. Advantageously, the locking mechanism comprises means for adjusting the force exerted by the elastic means on the latch when the latch is in the position locking. Thus, the triggering force can be adjusted to improve safety or to avoid inadvertent tripping.
  • In a locking configuration, one end of the movable latch protrudes from an inner face of the housing so as to be housed in a recess provided on a wall of the insert opposite, when the insert is placed in the insert housing.
  • The lock has the shape of a pawn.
  • The locking mechanism comprises an abutment for limiting the movement of the lock towards the housing of the insert. The stop allows to retain the exit of the lock and thus to control the emerging part of the lock head, which is important to ensure the locking force of the insert by the lock. This also makes it possible not to lose the lock by keeping it always secured to the body of the handle. According to one embodiment, the stop is a retaining pin cooperating with a cavity formed in the lock.
  • The insert housing has a flared shape widening towards the upper opening and in that the walls of the insert cooperating with the insert housing are inclined and have a generally complementary shape, for guiding by shape cooperation. engagement of the insert in the insert housing. The engagement of the insert in the insert housing is thus aided by the shape-forming guide between the flared shape of the insert housing and the inclined walls of complementary shape of the insert. The engagement of the strap is thus fast and easy.
  • The insert includes a transverse hinge shaft connecting the strap to the insert so as to allow rotation of the strap about an axis parallel to the lateral direction when the insert is mounted in the body. Advantageously, the insert comprises a recess in which is housed the transverse articulation shaft, the recess having an upper opening, opening on an upper surface of the insert, and a rear opening, extending in a posterior transverse direction , when the insert is retained in the body, the body having a rear clearance aligned with the rear opening when the insert is retained in the body, to allow the lateral pivoting of the strap between a vertical position and a horizontal position. The strap can therefore pivot freely relative to the handle body at an angle of at least 90 ° between the axial or vertical position and the lateral or horizontal position, making the use of the stick flexible and comfortable. The strap forms, for example, a first loop surrounding the hinge shaft which extends in the width of the strap and forms a second loop consecutive to the first loop for the passage of the hand of the user. Thus, when the user holds the handle and the strap surrounds his wrist, the support on the strap directed downward is transmitted on the body of the handle by the strap. The entire width of the strap thus participates in the recovery of thrust force. In addition, the strap is compact and is fully integrated in the knob in the lateral position, which improves its robustness.
  • The upper surface of the insert has an upper contour in continuity with an upper end of the handle body when the insert is retained in the handle body. The upper end of the stick can thus maintain a generally ergonomic shape, flat or curved, facilitating the grip by the palm of the hand of the skier climbing, for example for the practice of free-ride or ski touring.

L'invention concerne également un bâton équipé d'une poignée telle que définie précédemment.The invention also relates to a stick equipped with a handle as defined above.

Sur ces figures, les éléments identiques portent les mêmes numéros de référence.In these figures, the identical elements bear the same reference numbers.

Par la suite, on utilise un repère orthonormé XYZ pour lequel les directions transversale X et latérale Y sont perpendiculaires entre elles et perpendiculaires à la direction longitudinale Z du bâton. La direction transversale X est orientée de l'arrière vers l'avant du bâton.Subsequently, an orthonormal coordinate system XYZ is used for which the transverse directions X and lateral Y are perpendicular to each other and perpendicular to the longitudinal direction Z of the stick. The transverse direction X is oriented from the rear to the front of the stick.

Le côté « inférieur » ou « bas » correspond au côté de la pointe du bâton par opposition au côté «supérieur» ou « haut » correspondant au côté du pommeau de la poignée du bâton. L'« avant » ou partie « antérieure » désigne la partie en référence au sens de marche avant de l'utilisateur pat opposition à l'« arrière » ou partie « postérieure ». On désigne également par « verticale », la direction longitudinale Z et par « horizontale », une direction perpendiculaire à la direction longitudinale Z. Ces définitions s'appliquent à tous les éléments de la poignée selon l'invention, dans sa configuration assemblée.The "bottom" or "bottom" side corresponds to the side of the stick tip as opposed to the "top" or "top" side corresponding to the side of the handle of the stick handle. The "front" or "anterior" part refers to the part referring to the forward direction of the user opposed to the "rear" or "posterior" part. Also referred to as "vertical", the longitudinal direction Z and "horizontal", a direction perpendicular to the longitudinal direction Z. These definitions apply to all elements of the handle according to the invention in its assembled configuration.

Les figures 1 à 5 représentent un premier mode de réalisation d'une poignée 1 de bâton, pour la pratique notamment du ski de fond, du ski alpin, du ski de randonnée, de « free ride », de la marche en raquette à neige ou de marche nordique.The Figures 1 to 5 represent a first embodiment of a handle 1 stick, for the practice including cross-country skiing, downhill skiing, ski touring, "free ride", snowshoeing or Nordic walking.

La poignée 1 comporte un corps 2 et une dragonne 3.The handle 1 comprises a body 2 and a strap 3.

Comme on peut le voir sur la figure 3, le corps 2 comporte de façon classique, un espace interne creux 21, généralement cylindrique débouchant dans la partie inférieure du corps 2. L'espace interne creux 21 est conformé pour recevoir une tige longitudinale du bâton, celle-ci se terminant généralement par une pointe comportant un embout et éventuellement une rondelle. L'axe de l'espace creux cylindrique 21 définit la direction longitudinale Z1 de la poignée 1.As can be seen on the figure 3 , the body 2 conventionally comprises a hollow internal space 21, generally cylindrical opening into the lower part of the body 2. The hollow internal space 21 is shaped to receive a longitudinal rod of the stick, the latter generally ending with a tip having a tip and possibly a washer. The axis of the cylindrical hollow space 21 defines the longitudinal direction Z1 of the handle 1.

A l'extérieur, le corps 2 comporte une partie de préhension 22 destinée à être saisie par l'utilisateur et pouvant comporter une succession de reliefs et de creux répartis longitudinalement pour guider les doigts et la paume de la main de l'utilisateur. Sur le sommet, l'extrémité supérieure 24 du corps 2 peut présenter une forme de pommeau, sensiblement bombée, adaptée pour l'appui de la paume de la main de l'utilisateur, notamment lors de phases de montée.Outside, the body 2 comprises a gripping portion 22 to be grasped by the user and may include a succession of reliefs and recesses distributed longitudinally to guide the fingers and the palm of the hand of the user. On the top, the upper end 24 of the body 2 may have a pommel shape, substantially curved, adapted for the support of the palm of the hand of the user, especially during climbing phases.

La dragonne 3 comporte une sangle 31 et un insert 32 pouvant être fixé de manière amovible dans un logement d'insert 25 du corps 2. Le logement d'insert 25 est ménagé sur le corps 2 de sorte que l'ouverture du logement d'insert 25 débouche dans l'extrémité supérieure 24. L'insert 32 peut donc être introduit ou retiré du logement d'insert 25 selon une direction axiale, c'est-à-dire selon une direction sensiblement parallèle à l'axe longitudinal Z1 de la poignée 1.The strap 3 comprises a strap 31 and an insert 32 that can be removably attached in an insert housing 25 of the body 2. The insert housing 25 is formed on the body 2 so that the opening of the housing of insert 25 opens into the upper end 24. The insert 32 can be introduced or removed from the insert housing 25 in an axial direction, that is to say in a direction substantially parallel to the longitudinal axis Z1 of the handle 1.

Le logement d'insert 25 présente, par exemple, une forme évasée s'élargissant vers l'ouverture supérieure. Ici, le logement d'insert 25 est défini par une face avant 251 et une face arrière 252, limitant le logement selon la direction X. Les faces avant 251 et arrière 252 ne sont pas verticales mais forme un angle entre elles, préférentiellement supérieur à 15°. L'insert 32 est également défini par une paroi avant 321 et une paroi arrière 322. Là aussi, les parois avant 321 et 322 ne sont pas « verticales » mais forment entre elles un angle sensiblement le même que l'angle entre les faces avant 251 et arrière 252. Lorsque l'insert 32 est mis en place dans le logement d'insert 25, la face avant 251 du logement est en vis-à-vis de la paroi avant 321 de l'insert. La face avant et la paroi avant coopèrent entre elles. De même, la face arrière 252 du logement est en vis-à-vis de la paroi arrière 322 de l'insert. La face arrière et la paroi arrière coopèrent entre elles. Les figures 3 à 5 illustrent cette construction des faces 251, 252 et parois 321, 322 inclinées « en V » et complémentaires.The insert housing 25 has, for example, a flared shape widening towards the upper opening. Here, the insert housing 25 is defined by a front face 251 and a rear face 252, limiting the housing in the direction X. The front faces 251 and 252 rear are not vertical but forms an angle between them, preferably greater than 15 °. The insert 32 is also defined by a front wall 321 and a rear wall 322. Here again, the front walls 321 and 322 are not "vertical" but form between them an angle substantially the same as the angle between the front faces. 251 and rear 252. When the insert 32 is placed in the insert housing 25, the front face 251 of the housing is vis-à-vis the front wall 321 of the insert. The front face and the front wall cooperate with each other. Similarly, the rear face 252 of the housing is vis-à-vis the rear wall 322 of the insert. The rear face and the rear wall cooperate with each other. The Figures 3 to 5 illustrate this construction faces 251, 252 and walls 321, 322 inclined "V" and complementary.

D'autres formes de réalisation complémentaires de forme évasée peuvent être envisagées telles que des formes pyramidales, en prisme, ou tronconiques. L'engagement de l'insert 32 dans le logement d'insert 25 est ainsi facilité par le guidage par coopération de formes entre la forme évasée du logement d'insert 25 et les parois de forme complémentaire de l'insert 32.Other complementary embodiments of flared shape may be envisaged such as pyramidal, prismatic or frustoconical shapes. The engagement of the insert 32 in the insert housing 25 is thus facilitated by the co-operating guidance of shapes between the flared shape of the insert housing 25 and the complementary shaped walls of the insert 32.

La dragonne 3 peut en outre comporter un arbre d'articulation 33 reliant la sangle 31 à l'insert 32.The strap 3 may further comprise a hinge shaft 33 connecting the strap 31 to the insert 32.

Dans l'exemple illustré, l'insert 32 présente un dégagement 323 dans sa partie supérieure formant une ouverture postérieure 3231 et une ouverture supérieure 3232. Ce dégagement 323 est délimité latéralement par deux parois latérales 3233, espacées d'une distance légèrement supérieure à la largeur de la sangle 31. Chacune des parois latérales est percée par un trou traversant 320. Les deux trous traversant 320 sont alignées selon une direction sensiblement parallèle à la direction Y, quand l'insert 32 est monté dans le corps 2. Chaque trou traversant 320 est destiné à recevoir une extrémité de l'arbre d'articulation 33. L'arbre d'articulation est monté serrant dans ces trous traversant.In the illustrated example, the insert 32 has a clearance 323 in its upper part forming a rear opening 3231 and an upper opening 3232. This clearance 323 is delimited laterally by two side walls 3233, spaced a distance slightly greater than the width of the strap 31. Each of the side walls is pierced by a through hole 320. The two through holes 320 are aligned in a direction substantially parallel to the Y direction, when the insert 32 is mounted in the body 2. Each through hole 320 is intended to receive one end of the hinge shaft 33. The hinge shaft is mounted clamping in these through holes.

Dans le cas présent, une partie de la sangle 31 entoure étroitement l'arbre d'articulation 33, l'arbre d'articulation 33 s'étendant dans la largeur de la sangle 31. L'arbre d'articulation 33 est donc logé dans une boucle 311 de la sangle 31, sans serrage, de sorte que la boucle puisse librement tourner autour de l'arbre d'articulation. La longueur de l'arbre d'articulation 33 est légèrement supérieure à la largeur de la sangle 31 de manière que les extrémités de l'arbre d'articulation 33 fassent saillie de la boucle. Par ailleurs, la sangle 31 forme une deuxième boucle 312 consécutive à la première boucle 311 pour le passage de la main de l'utilisateur.In this case, a portion of the strap 31 closely surrounds the hinge shaft 33, the hinge shaft 33 extending in the width of the strap 31. The hinge shaft 33 is housed in a loop 311 of the strap 31, without tightening, so that the loop can freely rotate around the hinge shaft. The length of the hinge shaft 33 is slightly greater than the width of the strap 31 so that the ends of the hinge shaft 33 protrude from the loop. Furthermore, the strap 31 forms a second loop 312 consecutive to the first loop 311 for the passage of the hand of the user.

Cette construction permet la rotation de la sangle 31 autour de l'arbre d'articulation transversal 33, c'est-à-dire, un axe parallèle à la direction Y quand l'insert 32 est monté dans le corps 2.This construction allows the rotation of the strap 31 around the transverse hinge shaft 33, that is to say, an axis parallel to the Y direction when the insert 32 is mounted in the body 2.

Avantageusement, le dégagement 323 est dimensionné pour permettre le pivotement de la sangle 31 autour de l'arbre d'articulation 33 d'un angle d'au moins 90°. Ainsi, la sangle peut basculer d'une configuration horizontale, pour laquelle la sangle s'étend sensiblement horizontalement vers l'arrière (figure 3), vers une position verticale, pour laquelle la sangle s'étend sensiblement verticalement vers le haut (figures 4 et 5), ou inversement.Advantageously, the clearance 323 is dimensioned to allow the pivoting of the strap 31 around the hinge shaft 33 at an angle of at least 90 °. Thus, the strap can tilt from a horizontal configuration, for which the strap extends substantially horizontally towards the rear ( figure 3 ), towards a vertical position, for which the strap extends substantially vertically upwards ( figures 4 and 5 ), Or vice versa.

Une fois l'insert 32 assemblé au corps 2, l'ouverture postérieure 3231 du dégagement 323 débouche dans la partie supérieure et postérieure de l'extrémité supérieure du corps 2. Avantageusement, le corps 2 comporte un dégagement arrière 28 communiquant avec le logement d'insert 26. Le dégagement arrière 28 est dimensionné de sorte que, lorsque l'insert 32 est retenu dans le corps 2, l'ouverture postérieure 3231 de l'insert 32 et le dégagement arrière 28 sont alignés, créant alors un évidement ouvert vers l'arrière du corps pour le logement de la sangle. Cela permet d'autoriser le basculement de la sangle 31 entre la configuration horizontale (figure 3) et la configuration verticale (figures 4 et 5). En conséquence, la dragonne 3 peut pivoter librement par rapport au corps d'un angle d'au moins 90° entre la configuration horizontale et la configuration verticale, tendant l'utilisation du bâton 1 souple et confortable.Once the insert 32 has been assembled to the body 2, the rear opening 3231 of the recess 323 opens into the upper and posterior part of the upper end of the body 2. Advantageously, the body 2 comprises a rear recess 28 communicating with the housing. The rear recess 28 is dimensioned so that when the insert 32 is retained in the body 2, the rear opening 3231 of the insert 32 and the rear recess 28 are aligned, thereby creating an open recess to the back of the body for the housing of the strap. This makes it possible to allow the strap 31 to tilt between the horizontal configuration ( figure 3 ) and the vertical configuration ( figures 4 and 5 ). Consequently, the strap 3 can pivot freely relative to the body at an angle of at least 90 ° between the horizontal configuration and the vertical configuration, tending the use of the stick 1 flexible and comfortable.

De plus, du fait que la dragonne 3 entoure l'arbre d'articulation transversal sur sa largeur, l'orientation de la sangle est telle que sa largeur reste toujours orientée selon une direction Y. Cette spécificité permet d'avoir un évidement 28 peu profond dans le corps 2 par rapport à une sangle dont l'orientation de la sangle serait telle que sa largeur reste toujours orientée selon une direction X ou Z. Dès lors, la solidité de la poignée est renforcée.In addition, because the strap 3 surrounds the transverse hinge shaft over its width, the orientation of the strap is such that its width is always oriented in a Y direction. This specificity allows to have a recess 28 bit deep in the body 2 with respect to a strap whose orientation of the strap would be such that its width always remains oriented in a direction X or Z. Therefore, the strength of the handle is reinforced.

Par ailleurs, lorsque l'utilisateur exerce un effort de poussée, via son poignet, sur la sangle, comme ce peut être le cas lors de la pratique du ski de fond, l'effort est transmis au corps par la sangle, au niveau de la partie inférieure du dégagement arrière 28 et de la partie inférieure de l'ouverture postérieure 3231 de l'insert 32. Cette construction permet d'obtenir une surface d'appui importante entre la sangle 31 et le corps 2. La sangle appuie donc sur toute la largeur de la sangle ou tout au moins sur une grande partie de la largeur de la sangle et sur une longueur additionnant la surface d'appui de la partie inférieure du dégagement arrière 28 et la surface d'appui de la partie inférieure de l'ouverture postérieure 3231. L'effort de poussée n'est donc pas seulement transmis par l'insert 32 mais également par la sangle 31 au niveau de cette zone de contact. L'insert et le corps sont donc moins sollicités ce qui permet une meilleure répartition des efforts de poussée. En outre, la dragonne 3, ainsi agencée, est compacte et est complétement intégrée dans le pommeau de l'extrémité supérieure 24 du corps en configuration horizontale (figure 3).Moreover, when the user exerts a pushing force, via his wrist, on the strap, as it may be the case during the practice of cross-country skiing, the force is transmitted to the body by the strap, at the level of the lower part of the rear clearance 28 and the lower part of the rear opening 3231 of the insert 32. This construction provides a large bearing surface between the strap 31 and the body 2. The strap therefore presses the entire width of the strap or at least over a large part of the width of the strap and over a length adding the bearing surface of the lower part of the rear clearance 28 and the bearing surface of the lower part of the posterior opening 3231. The pushing force is therefore not only transmitted by the insert 32 but also by the strap 31 at this contact area. The insert and the body are therefore less stressed which allows a better distribution of the thrust forces. In addition, the strap 3, thus arranged, is compact and is completely integrated in the head of the upper end 24 of the body in a horizontal configuration ( figure 3 ).

Alternativement, la sangle peut être assemblée différemment à l'insert. Par exemple, l'arbre d'articulation peut passer à travers un trou perforant la largeur de la sangle.Alternatively, the strap can be assembled differently to the insert. For example, the hinge shaft can pass through a hole perforating the width of the strap.

Selon un autre aspect, on prévoit que la surface supérieure 325 de l'insert 32 obturant présente une forme en continuité avec l'extrémité supérieure 24 du corps 2 lorsque l'insert 32 est retenu dans le corps 2. Le sommet 325 présente par exemple une forme arrondie et bombée. L'extrémité supérieure de la poignée 1 conserve ainsi une forme générale bombée ergonomique facilitant la prise par la paume de la main de l'utilisateur. Ainsi, lors de l'ascension de pente, notamment pour la pratique du free-ride ou du ski de randonnée, l'utilisateur peut pousser sur le pommeau du bâton sans sentit une pression localisée sur sa main. En effet, l'effort de poussée exercé par la paume est répartie sur une grande surface ce qui diminue les pointes d'effort localisées.According to another aspect, it is expected that the upper surface 325 of the closing insert 32 has a shape in continuity with the upper end 24 of the body 2 when the insert 32 is retained in the body 2. The top 325 has for example a rounded and curved shape. The upper end of the handle 1 thus retains a generally ergonomic convex shape facilitating the grip by the palm of the hand of the user. Thus, during the ascent of the slope, especially for the practice of free-ride or ski touring, the user can push on the pommel of the stick without felt a localized pressure on his hand. Indeed, the thrust force exerted by the palm is distributed over a large area which reduces localized stress peaks.

La dragonne se compose donc de trois pièces simples, économiques et faciles à réaliser : la sangle 31, l'insert 32 et l'arbre de 'articulation 33. L'insert 32 ne comprend aucune partie déformable ce qui le rend robuste.The strap therefore consists of three simple pieces, economical and easy to achieve: the strap 31, the insert 32 and the hinge shaft 33. The insert 32 does not include any deformable part which makes it robust.

La poignée 1 comporte en outre un mécanisme de verrouillage 10 comportant un verrou 4 mobile transversalement entre une position de saillie, correspondant à la position de verrouillage, et une position rétractée.The handle 1 further comprises a locking mechanism 10 comprising a latch 4 movable transversely between a projecting position, corresponding to the locking position, and a retracted position.

Le verrou 4 présente par exemple la forme d'un pion dont une extrémité, la tête de verrou 41, présente une forme arrondie sensiblement hémisphérique. Le verrou 4 est placé dans un logement transversal 26 du corps de poignée 2, orientée selon une direction parallèle à la direction X. La tête du verrou 41 pointe vers l'arrière du corps 2. Le logement transversal 26 présente par exemple une forme cylindrique ayant un diamètre légèrement supérieur au diamètre du verrou ce qui permet au verrou de coulisser librement dans le logement transversal. Dans cet exemple, le logement transversal 26 est centré horizontalement et passe donc par le contre du corps 2. Le logement transversal 26 comporte un premier orifice 261 débouchant dans le logement d'insert 25.The lock 4 has for example the shape of a pin whose one end, the lock head 41, has a substantially hemispherical rounded shape. The latch 4 is placed in a transverse housing 26 of the handle body 2, oriented in a direction parallel to the direction X. The head of the latch 41 points towards the rear of the body 2. The transverse housing 26 has for example a cylindrical shape having a diameter slightly greater than the diameter of the lock which allows the lock to slide freely in the transverse housing. In this example, the transverse housing 26 is centered horizontally and therefore passes through the body against the back 2. The transverse housing 26 has a first orifice 261 opening into the insert housing 25.

En position de saillie ou position de verrouillage, la tête du verrou 4.1 fait saillie de la face avant 251 du logement d'insert 25, à travers le premier orifice 261.In the protruding position or locking position, the head of the lock 4.1 protrudes from the front face 251 of the insert housing 25, through the first orifice 261.

Dans ce premier mode de réalisation, l'insert 32 comprend un évidement transversal 324 ménagé dans la paroi avant 321 coopérant avec la face avant 251 du logement d'insert 25. L'évidement transversal 324 est dimensionné et positionné de manière à recevoir la tête de verrou 41 lorsque l'insert 32 est mis en place dans le logement d'insert 25. L'évidement transversal 324 est par exemple cylindrique. Ainsi, lorsque l'insert 32 est introduit dans le logement d'insert 25, en déplaçant le verrou 4 en position de verrouillage, celui-ci bloque le déplacement axial de l'insert 32, c'est-à-dire, selon une direction parallèle à l'axe Z. En effet, le verrou 4 coopère avec l'évidement transversal 324 ce qui permet de retenir l'insert 32 dans le corps 2. Le verrouillage de l'insert est ainsi assuré.In this first embodiment, the insert 32 comprises a transverse recess 324 formed in the front wall 321 cooperating with the front face 251 of the insert housing 25. The transverse recess 324 is dimensioned and positioned to receive the head latch 41 when the insert 32 is put in place in the insert housing 25. The transverse recess 324 is for example cylindrical. Thus, when the insert 32 is inserted into the insert housing 25, by moving the latch 4 in the locking position, this locks the axial displacement of the insert 32, that is to say, in a direction parallel to the axis Z. Indeed, the latch 4 cooperates with the transverse recess 324 which allows to retain the insert 32 in the body 2. The locking the insert is thus insured.

Le mécanisme de verrouillage 10 comprend également un moyen élastique 5, ici, il s'agit d'un ressort hélicoïdal, exerçant un effort sur le verrou pour l'amener en position de verrouillage. Ainsi, grâce au ressort 5, la configuration de verrouillage est privilégiée.The locking mechanism 10 also comprises an elastic means 5, here it is a helical spring, exerting a force on the latch to bring it into the locking position. Thus, thanks to the spring 5, the locking configuration is preferred.

Le mécanisme de verrouillage 10 comprend aussi, dans cet exemple, une goupille de retenue 6 destinée à coopérer avec une cavité 42 ménagée dans le verrou 4. Cette coopération permet le déplacement transversal du verrou 4, c'est-à-dire, selon une direction parallèle à la direction X, jusqu'à une position transversale déterminée, la position de verrouillage, dans un sens. Par ailleurs, cette coopération peut également limiter le déplacement transversal du verrou dans l'autre sens.The locking mechanism 10 also comprises, in this example, a retaining pin 6 intended to cooperate with a cavity 42 formed in the latch 4. This cooperation allows the transverse displacement of the latch 4, that is to say, according to a direction parallel to the X direction, to a determined transverse position, the locking position, in one direction. Moreover, this cooperation can also limit the transverse displacement of the lock in the other direction.

La goupille de retenue 6 est reçue dans un logement de goupille 27 du corps de poignée 2 débouchant dans le logement transversal 26 recevant le verrou 4. Le logement de goupille 27 et la goupille de retenue 6 présentent des formes complémentaires, par exemple cylindriques, la goupille de retenue 6 étant par exemple montée en force ou montée serrante, dans le logement de goupille 27. L'axe du logement de goupille 27 s'étend par exemple sensiblement longitudinalement c'est-à-dire, selon une direction parallèle à la direction Z, de manière à pouvoir bloquer le déplacement transversal du verrou 4.The retaining pin 6 is received in a pin housing 27 of the handle body 2 opening into the transverse housing 26 receiving the latch 4. The pin housing 27 and the retaining pin 6 have complementary shapes, for example cylindrical, the retaining pin 6 being for example mounted in force or mounted tightly, in the pin housing 27. The axis of the pin housing 27 extends for example substantially longitudinally that is to say, in a direction parallel to the Z direction, so as to block the transverse displacement of the latch 4.

Dans cet exemple, la cavité 42 est dimensionnée par rapport à la position de la goupille de retenue 6 assemblée dans le corps 2 de sorte que la goupille de retenue 6 entre en contact avec une première face 421 de la cavité 42 lorsque le verrou 4 est en position de saillie ou de verrouillage (figures 3 et 5) et de sorte que la goupille de retenue 6 entre en contact avec une deuxième face 422 de la cavité 42 définissant une course de retrait maximum lorsque le verrou 4 est en position rétractée. La cavité 42 s'étend dans la direction transversale, parallèle à la direction X, pour bloquer le déplacement transversal du verrou 4. La longueur transversale de la cavité 42 définit la course de déplacement maximum entre la position rétractée et la position de saillie. La goupille de retenue 6 forme ainsi une double butée pour le déplacement du verrou 4 : un arrêt dans chaque sens.In this example, the cavity 42 is dimensioned with respect to the position of the retaining pin 6 assembled in the body 2 so that the retaining pin 6 comes into contact with a first face 421 of the cavity 42 when the latch 4 is in protruding or locking position ( figures 3 and 5 ) and so that the retaining pin 6 comes into contact with a second face 422 of the cavity 42 defining a maximum withdrawal stroke when the latch 4 is in the retracted position. The cavity 42 extends in the transverse direction, parallel to the X direction, to block the transverse displacement of the latch 4. The transverse length of the cavity 42 defines the maximum displacement path between the retracted position and the protruding position. The retaining pin 6 thus forms a double stop for the displacement of the latch 4: a stop in each direction.

La cavité 42 est par exemple un trou traversant de forme oblongue dans lequel passe la goupille de retenue 6. Le logement de goupille 27 s'étend longitudinalement dans le corps 2, au-delà du logement transversal 26. La goupille de retenue 6 traverse alors la cavité 42 du verrou 4, ce qui permet d'assurer une meilleure retenue du verrou 4. En outre, la cavité 42 peut être centrée dans le verrou 4.The cavity 42 is for example an oblong through-hole in which the retaining pin 6 passes. The pin housing 27 extends longitudinally in the body 2, beyond the transverse housing 26. The retaining pin 6 then passes through the cavity 42 of the latch 4, which ensures a better retention of the latch 4. In addition, the cavity 42 can be centered in the latch 4.

Selon un autre mode de réalisation non représenté, la cavité est une encoche présentant une ouverture latérale ou annulaire, ce qui permet d'éviter les éventuels problèmes d'alignement de l'axe de la goupille de retenue 6 avec la cavité du verrou 4 au moment du montage des éléments de la poignée 1.According to another embodiment not shown, the cavity is a notch having a lateral or annular opening, which makes it possible to avoid any problems of alignment of the axis of the retaining pin 6 with the cavity of the lock 4 at moment of assembly of the elements of the handle 1.

La goupille de retenue 6 permet ainsi de retenir la sortie du verrou 4 et donc de maîtriser la partie émergeante de la tête de verrou 41 dans le logement d'insert 25. On s'assure alors de la position de la tête de verrou 41 en position de verrouillage, ce qui est important pour s'assurer de la coopération effective entre le verrou 4 et l'évidement transversal 324 de l'insert. Par ailleurs, la partie du verrou en saillie de la face avant 251 du logement d'insert 25 contribue à la détermination de l'effort d'enclenchement et de déclenchement de la dragonne.The retaining pin 6 thus makes it possible to retain the output of the latch 4 and thus to control the emerging part of the latch head 41 in the insert housing 25. This ensures the position of the latch head 41 locking position, which is important to ensure the effective cooperation between the latch 4 and the transverse recess 324 of the insert. Furthermore, the portion of the latch projecting from the front face 251 of the insert housing 25 contributes to the determination of the engagement and triggering force of the strap.

Pour que le verrou puisse se rétracter sous une action axiale sur l'insert, la partie du verrou en saillie de la face avant 251 présente, quand le verrou est en position de verrouillage, une inclinaison par rapport à un plan horizontal XY. En effet, lorsqu'on tire axialement sur l'insert, le bord inférieur de l'évidement transversal 324 entre en contact avec la tête de verrou 41. Ainsi, grâce à la pente de la partie du verrou en saillie de la face avant 251, l'effort axial est transposé en effort transversal ce qui permet de pousser le verrou 4 à l'intérieur de son logement transversal 26. Cette pente peut être constante (pyramide, cône) ou variable (hémisphère). Dans l'exemple illustré, la tête de verrou 41 est hémisphérique, ce qui permet cette transposition d'effort. Alternativement, la tête de verrou 41 peut se présenter différemment, par exemple, sous la forme d'une pyramide, d'un cône. Ce qui importe est que la tête de verrou 41 présente une pente bien orientée, inclinée d'un angle par rapport à un plan horizontal.In order for the latch to retract under axial action on the insert, the portion of the latch projecting from the front face 251 has, when the latch is in the locked position, an inclination with respect to a horizontal plane XY. Indeed, when axially pulling on the insert, the lower edge of the transverse recess 324 comes into contact with the lock head 41. Thus, due to the slope of the portion of the lock projecting from the front face 251 , the axial force is transposed into transverse force which allows to push the latch 4 inside its transverse housing 26. This slope can be constant (pyramid, cone) or variable (hemisphere). In the example shown, the latch head 41 is hemispherical, which allows this transposition of effort. Alternatively, the lock head 41 may be different, for example, in the form of a pyramid, a cone. What is important is that the latch head 41 has a well oriented slope inclined at an angle to a horizontal plane.

D'autre part, en limitant le déplacement au moins dans un sens, celui en direction de la position de verrouillage, on s'assure en plus de ne pas perdre d'éléments du mécanisme de verrouillage 10. Enfin, cette butée, réalisée par la coopération entre la goupille 6 et la cavité 42, permet d'obtenir une position de verrouillage stable, précise et définie.On the other hand, by limiting the displacement at least in one direction, that towards the locking position, it is ensured in addition not to lose elements of the locking mechanism 10. Finally, this stop, made by the cooperation between the pin 6 and the cavity 42 makes it possible to obtain a stable, precise and defined locking position.

L'effort d'enclenchement et de déclenchement de la dragonne est principalement déterminé par le moyen élastique 5 permettant de ramener le verrou 4 dans la position de verrouillage. Il est donc avantageux de pouvoir régler l'effort exercé sur le verrou 4 par ce moyen élastique 5.The engagement and triggering force of the strap is mainly determined by the resilient means 5 for returning the latch 4 in the locking position. It is therefore advantageous to be able to adjust the force exerted on the latch 4 by this elastic means 5.

Le mécanisme de verrouillage 10 peut ainsi comporter un moyen de réglage du seuil de déclenchement, c'est-à-dire, pour régler l'effort exercé par le moyen élastique sur le verrou notamment lorsque le verrou est dans la position de verrouillage. Ce moyen de réglage, peut être agencé dana le logement transversal 26 recevant le verrou 4.The locking mechanism 10 may thus comprise means for adjusting the triggering threshold, that is to say, for adjusting the force exerted by the elastic means on the lock, in particular when the lock is in the locking position. This adjustment means can be arranged in the transverse housing 26 receiving the latch 4.

Selon ce premier mode de réalisation, le logement transversal 26 qui reçoit le verrou 4 est traversant. Il débouche, d'une part, dans le logement d'insert 25, via un premier orifice 261, comme on l'a vu précédemment, et d'autre part, sur l'extérieur, à l'avant du corps 2, via un deuxième orifice 262. Une portion interne 263 du logement transversal cylindrique 26, située du côté du deuxième orifice 262 débouchant à l'avant du corps de poignée 2, est filetée. Une vis de réglage 7 est alors vissée dans la portion interne filetée 263 afin d'obturer le logement transversal 26.According to this first embodiment, the transverse housing 26 which receives the latch 4 is through. It opens, on the one hand, in the insert housing 25, via a first orifice 261, as we have seen previously, and on the other hand, on the outside, at the front of the body 2, via a second orifice 262. An inner portion 263 of the cylindrical transverse housing 26, located on the side of the second orifice 262 opening at the front of the handle body 2, is threaded. An adjustment screw 7 is then screwed into the internal threaded portion 263 in order to seal the transverse housing 26.

Le ressort 5 est interposé entre la vis de réglage 7 et le verrou 4. Une extrémité du ressort 5 est en contact avec la vis de réglage 7 et une deuxième extrémité du ressort 5 est en contact avec le verrou 4. Cet agencement permet de pouvoir contraindre plus ou moins le ressort 5 contre le verrou 4 suivant la position transversale de la vis de réglage 7. Pour modifier le seuil de déclenchement du mécanisme de verrouillage, c'est-à-dire la force avec laquelle la dragonne 3 est retenue par le verrou 4, il suffit donc de visser ou dévisser la vis de réglage 7. La vis de réglage 7 constitue donc le moyen de réglage du seuil de déclenchement.The spring 5 is interposed between the adjusting screw 7 and the latch 4. One end of the spring 5 is in contact with the adjusting screw 7 and a second end of the spring 5 is in contact with the latch 4. This arrangement makes it possible to more or less force the spring 5 against the latch 4 according to the transverse position of the adjusting screw 7. To modify the threshold triggering the locking mechanism, that is to say the force with which the strap 3 is retained by the latch 4, it is sufficient to screw or unscrew the adjusting screw 7. The adjusting screw 7 is therefore the means setting the trigger threshold.

Le moyen de réglage du seuil de déclenchement est ainsi facilement accessible au travers du deuxième orifice 262 du logement transversal 26, à l'avant de la poignée 1, ce qui est pratique.The means for adjusting the trigger threshold is thus easily accessible through the second orifice 262 of the transverse housing 26, in front of the handle 1, which is convenient.

Le logement d'insert 25 est par exemple excentré et décalé vers l'arrière de l'extrémité supérieure 24 du corps de poignée 2, notamment pour permettre le logement à l'avant du moyen de verrouillage 10 intégrant un moyen de réglage 7 du seuil de déclenchement Pour obtenir ce décalage, le mécanisme de verrouillage 10 agit, via le verrou 4, uniquement sur un coté de l'insert 32, la paroi antérieure 321.The insert housing 25 is, for example, eccentric and offset towards the rear of the upper end 24 of the handle body 2, in particular to allow the housing to be located at the front of the locking means 10 incorporating a means 7 for adjusting the threshold In order to obtain this offset, the locking mechanism 10 acts, via the latch 4, only on one side of the insert 32, the front wall 321.

En position rétractée, la tête du verrou 41 peut rentrer au moins partiellement dans le logement transversal 26. Le verrou 4 ne coopère plus avec l'évidement transversal 324, ce qui permet de libérer l'insert 32 du corps 2. Le verrou 4 est en position déverrouillée.In the retracted position, the head of the latch 41 can fit at least partially into the transverse housing 26. The latch 4 no longer cooperates with the transverse recess 324, which allows the insert 32 to be released from the body 2. The latch 4 is in unlocked position.

Dans ce mode réalisation, le mécanisme de verrouillage 10 comprend le verrou 4, le ressort 5, la goupille de retenue 6, la vis de réglage 7. Tous ces éléments sont logés dans la partie supérieure antérieure du corps 2.In this embodiment, the locking mechanism 10 comprises the latch 4, the spring 5, the retaining pin 6, the adjusting screw 7. All these elements are housed in the upper anterior part of the body 2.

Le dégagement de la dragonne va maintenant être expliqué.The release of the strap will now be explained.

Lorsqu'une traction axiale déterminée est exercée sur l'insert 32, comme schématisé par la flèche Fa sur la figure 4, l'insert 32 repousse le verrou 4 à l'encontre de son rappel élastique. Cette action provoque l'escamotage partiel de la tête de verrou 41 dans le logement transversal 26 afin de désengager le verrou 4 de l'évidement transversal 324 de l'insert 32. La tête verrou 41 hémisphérique aide au déplacement du verrou vers une position escamotée.When a determined axial tension is exerted on the insert 32, as shown by the arrow F on the figure 4 , the insert 32 pushes the latch 4 against its elastic return. This action causes partial retraction of the latch head 41 in the transverse housing 26 to disengage the latch 4 of the transverse recess 324 of the insert 32. The hemispherical latch head 41 helps move the latch to a retracted position .

La traction axiale déterminée Fa est une sollicitation excessive dépassant une force de traction axiale normale. On définit une traction axiale sensiblement parallèle à l'axe longitudinal Z1 du corps 2, une force exercée axialement dans l'axe longitudinal Z1 de la poignée 1, dans un cône centré sur l'axe longitudinal Z1 avec une ouverture maximale de 60°. Une traction axiale Fa excessive peut être exercée par exemple parce que la pointe du bâton 1 est restée coincée par exemple sous les éboulis d'une avalanche ou dans les racines d'un arbre. Dans ce cas, le bâton commence à tirer trop fort sur le poignet et donc sur le bras de l'utilisateur avec une composante axiale importante du fait notamment de la vitesse de l'utilisateur par rapport à l'arrêt du bâton. Le risque associé à ce coincement est la blessure de l'utilisateur. Grâce au déclenchement de la dragonne, on limite ce risque.The axial traction determined Fa is an excessive stress exceeding a normal axial tensile force. An axial tension substantially parallel to the longitudinal axis Z1 of the body 2, a force exerted axially in the longitudinal axis Z1 of the handle 1, is defined in a cone centered on the longitudinal axis Z1 with a maximum opening of 60 °. Excessive axial traction Fa may be exerted for example because the tip of the stick 1 has remained stuck for example under the scree of an avalanche or in the roots of a tree. In this case, the stick starts to pull too hard on the wrist and thus on the user's arm with a significant axial component, in particular because of the speed of the user compared to the stopping of the stick. The risk associated with this jamming is the injury of the user. By triggering the strap, this risk is limited.

Le seuil de déclenchement est la force axiale maximale à exercer sur la dragonne avant que celle-ci se désolidarise du corps de la poignée. C'est la valeur de traction axiale minimum à exercer sur l'insert 32 pour vaincre In force rappel du ressort 5. En tirant axialement sur l'insert 32, celui-ci agit sur la tête du verrou 41 pour que le verrou se rétracte dans son logement transversal 26. Ce déplacement du verrou 4 comprime le ressort 5. En conséquence, pour obtenir le déplacement du verrou souhaité, c'est-à-dire, un déplacement permettant au verrou 4 de ne plus coopérer avec l'évidement transversal 324 de l'insert 32, il faut exercer un effort déterminé sur le verrou. Cet effort est directement lié à la raideur du ressort 5. Cet effort est directement transposable en un effort de traction axiale minimum à exercer sur l'insert 32 : c'est le seuil de déclenchement. Comme nous l'avons vu précédemment, la raideur du ressort, et donc le seuil de déclenchement, peut être ajustée par le moyen de réglage 7.The trigger threshold is the maximum axial force to be exerted on the strap before it separates from the body of the handle. This is the minimum axial tensile value to be exerted on the insert 32 to overcome In force return spring 5. By pulling axially on the insert 32, it acts on the head of the lock 41 for the lock retracts in its transverse housing 26. This displacement of the latch 4 compresses the spring 5. Consequently, to obtain the displacement of the desired latch, that is to say, a displacement allowing the latch 4 to no longer cooperate with the transverse recess 324 of the insert 32, it is necessary to exercise a determined effort on the lock. This force is directly related to the stiffness of the spring 5. This force is directly transposable into a minimum axial tensile force to exert on the insert 32 is the trigger threshold. As we have seen previously, the stiffness of the spring, and therefore the triggering threshold, can be adjusted by the adjusting means 7.

Puis, lorsque la dragonne 3 est complètement détachée du corps 2, la tête du verrou 41 retourne en position de saillie sous l'effet de la sollicitation élastique du ressort 5. La sortie du verrou 4 du logement transversal 26 est limitée par la butée de la goupille de retenue 6 dans la première face de la cavité 42 du verrou 4 (figure 5).Then, when the strap 3 is completely detached from the body 2, the head of the latch 41 returns to the protruding position under the effect of the elastic biasing of the spring 5. The output of the latch 4 of the transverse housing 26 is limited by the stop of the retaining pin 6 in the first face of the cavity 42 of the latch 4 ( figure 5 ).

Pour repositionner la dragonne 3, il suffit d'appliquer un effort axial inverse sur l'insert 32. L'introduction de l'insert 32 dans le logement d'insert 25 est ainsi rapide et facile, notamment du fait du guidage par coopération de forme entre les parois inclinées de l'insert 32 et la forme évasée du logement d'insert 25.To reposition the strap 3, it is sufficient to apply an inverse axial force on the insert 32. The introduction of the insert 32 in the insert housing 25 is thus quick and easy, especially because of the co-operation of form between the inclined walls of the insert 32 and the flared shape of the insert housing 25.

Ainsi, un effort axial agit sur le verrou, soit pour enclencher le mécanisme de verrouillage 10, soit pour le déclencher. Cela permet de solidariser la dragonne 3 avec le corps 2 quand on introduit l'insert 32 dans le logement d'insert 25. L'effort axial en direction du rapprochement de l'insert 32 vers le corps 2 provoque l'enclenchement du mécanisme de verrouillage 10. A l'inverse, un effort axial en direction de l'écartement de l'insert 32 par rapport au corps 2 provoque le déclenchement du mécanisme de verrouillage 10. La dragonne 3 se désolidarise alors du corps 2.Thus, an axial force acts on the latch, either to engage the locking mechanism 10, or to trigger it. This makes it possible to secure the strap 3 with the body 2 when inserting the insert 32 in the insert housing 25. The axial force towards the bringing of the insert 32 towards the body 2 causes the engagement mechanism to engage. In contrast, an axial force towards the spacing of the insert 32 relative to the body 2 causes the triggering of the locking mechanism 10. The strap 3 then disengages from the body 2.

En utilisation normale, il est souhaitable que la dragonne ne se débroche pas. Il faut donc prévoir le maintien de la solidarisation de l'insert 32 dans le corps 2.In normal use, it is desirable that the strap does not disconnect. It is therefore necessary to provide for maintaining the attachment of the insert 32 in the body 2.

Pour cela, l'insert 32 et le logement d'insert 25 sont conçus de sorte que la mise en place de l'insert dans le logement peut se faire selon une direction sensiblement axiale Z. Ainsi, si on exerce un effort sur l'insert selon une autre direction que la direction axiale Z, l'insert reste dans son logement. Il est toujours solidaire du corps 2.For this, the insert 32 and the insert housing 25 are designed so that the introduction of the insert in the housing can be in a substantially axial direction Z. Thus, if one exerts a force on the insert in a direction other than the axial direction Z, the insert remains in its housing. He is always attached to the body 2.

La plupart du temps, lors de la pratique normale d'une activité nécessitant l'usage de ce type de bâton, comme par exemple le ski alpin, la dragonne est sensiblement orientée horizontalement, c'est-à-dire, perpendiculairement à l'axe Z du bâton. La dragonne est alors dans une configuration horizontale pour laquelle une partie de la dragonne vient se loger dans l'ouverture postérieure 3231 de l'insert 32 et dans le dégagement arrière 28 du corps 2. Dans certain cas, notamment lors de la pratique du ski de fond ou de la randonnée, la dragonne peut être orientée parallèlement à l'axe Z du bâton mais en direction de la pointe. Aucun effort n'est exercé sur l'insert 32 pour l'écarter du corps 2, c'est même le contraire. Au niveau du pommeau du bâton, cette configuration de la dragonne est similaire à la configuration horizontale dans le sens où la première boucle 311 est orientée horizontalement. La différence porte essentiellement sur l'orientation de la seconde boucle 312 de la sangle 31.Most of the time, during the normal practice of an activity requiring the use of this type of stick, such as alpine skiing, the strap is substantially oriented horizontally, that is to say, perpendicular to the Z axis of the stick. The strap is then in a horizontal configuration for which a portion of the strap is housed in the rear opening 3231 of the insert 32 and in the rear clearance 28 of the body 2. In some cases, especially when skiing background or hiking, the strap can be oriented parallel to the Z axis of the stick but towards the tip. No effort is exerted on the insert 32 to separate it from the body 2, it is even the opposite. At the knob of the stick, this configuration of the strap is similar to the horizontal configuration in the sense that the first loop 311 is oriented horizontally. The difference essentially relates to the orientation of the second loop 312 of the strap 31.

Cette conception permet de ne pas actionner le mécanisme de verrouillage 10 lorsque la dragonne 4 n'est pas sollicitée axialement, dans le sens de l'écartement relatif entre l'insert 32 et le corps 2, comme c'est le cas en utilisation normale. La dragonne 3 reste donc solidaire du corps 2 dans cette configuration.This design makes it possible not to actuate the locking mechanism 10 when the strap 4 is not biased axially, in the direction of the relative spacing between the insert 32 and the body 2, as is the case in normal use. . The strap 3 remains attached to the body 2 in this configuration.

La dragonne est donc amovible sous l'effet d'une traction axiale déterminée exercée sur la sangle 31 et maintenue bloquée dans le corps de poignée lors de sollicitations transversales ou horizontales.The strap is therefore removable under the effect of a determined axial traction exerted on the strap 31 and kept locked in the handle body during transverse or horizontal stresses.

Le mécanisme de verrouillage permet ainsi d'assurer la sécurité de l'utilisateur en permettant le détachement de la dragonne 3 dans des situations susceptibles de blesser l'utilisateur mais en évitant les déclenchements intempestifs dans les situations non souhaitées. De plus, le mécanisme de verrouillage est simple, compact et robuste. Il s'intègre parfaitement à la poignée 1. Il ne présente pas de pièces déformables par encliquetage susceptibles de se rompre. Selon cette invention, le corps 2 est peu sollicité en déformation ce qui permet de le préserver, d'autant plus que, généralement, il s'agit d'une pièce coûteuse, En outre, la maintenance est aisée car les éléments sont facilement interchangeables en cas de détérioration.The locking mechanism thus ensures the safety of the user by allowing the detachment of the strap 3 in situations likely to injure the user but avoiding inadvertent tripping in undesired situations. In addition, the locking mechanism is simple, compact and robust. It integrates perfectly with the handle 1. It does not present deformable snap-fastenable parts that can break. According to this invention, the body 2 is not stressed in deformation which allows to preserve it, especially since it is usually an expensive part, In addition, maintenance is easy because the elements are easily interchangeable in case of deterioration.

Les figures 6a et 6b représentent un autre exemple de réalisation d'une poignée de bâton dans laquelle un arbre de liaison 34 remplace l'insert.The Figures 6a and 6b represent another embodiment of a stick handle in which a connecting shaft 34 replaces the insert.

Dans ce mode de réalisation, le mécanisme de verrouillage est intégré dans l'arbre de liaison 34. L'arbre de liaison 34 est configuré pour s'insérer dans un logement d'arbre 29 du corps 2. Le logement d'arbre 29 est ménagé dans le corps 2 de sorte que l'ouverture du logement d'arbre 29 débouche dans l'extrémité supérieure 24.In this embodiment, the locking mechanism is integrated in the link shaft 34. The link shaft 34 is configured to fit into a shaft housing 29 of the body 2. The shaft housing 29 is formed in the body 2 so that the opening of the shaft housing 29 opens into the upper end 24.

L'arbre de liaison 34 peut donc être reçu et retiré axialement du logement d'arbre 29, c'est-à-dire dans une direction sensiblement parallèle à l'axe longitudinal Z1 de la poignée de bâton 1.The connecting shaft 34 can thus be received and removed axially from the shaft housing 29, that is to say in a direction substantially parallel to the longitudinal axis Z1 of the stick handle 1.

Le corps 2 comporte un dégagement arrière 28 communiquant avec le logement d'arbre 29 permettant à la dragonne 3 de pivoter librement par rapport au corps de poignée d'un angle d'au moins 90° entre une position verticale et une position horizontale.The body 2 has a rear clearance 28 communicating with the shaft housing 29 allowing the strap 3 to pivot freely relative to the handle body at an angle of at least 90 ° between a vertical position and a horizontal position.

Comme représenté schématiquement sur la figure 6b, l'arbre de liaison 34 forme un tube orienté transversalement, c'est-à-dire, selon une direction sensiblement parallèle à la direction Y, lorsque l'arbre de liaison est assemblé dans le corps 2. A l'intérieur du tube 34, deux verrous 4 peuvent coulisser le long du tube. Chaque verrou 4 est disposé à une extrémité du tube 34 et peut se déplacer entre une position de saillie, pour laquelle une partie du verrou 4 fait saillie d'une extrémité du tube 34, et une position rétractée, pour laquelle le verrou rentre à l'intérieur du tube 34.As shown schematically on the figure 6b , the connecting shaft 34 forms a transversely oriented tube, that is to say, in a direction substantially parallel to the direction Y, when the connecting shaft is assembled in the body 2. Inside the tube 34, two locks 4 can slide along the tube. Each latch 4 is disposed at one end of the tube 34 and can move between a protruding position, for which a portion of the latch 4 projects from one end of the tube 34, and a retracted position, for which the latch returns to the latch. inside the tube 34.

Les verrous 4 sont rappelés élastiquement en position de saillie par deux ressorts 5 du mécanisme de verrouillage. Les ressorts 5 sont interposés entre les verrous 4 et un arbre interne 6, inséré dans le tube 34.The latches 4 are resiliently biased into projecting position by two springs 5 of the locking mechanism. The springs 5 are interposed between the latches 4 and an internal shaft 6, inserted in the tube 34.

Avantageusement, les extrémités du tube 34 sont déformées de manière à maintenir les verrous 4 à l'intérieur du tube. Ces déformations 341 servent de butées pouf les verrous.Advantageously, the ends of the tube 34 are deformed so as to maintain the latches 4 inside the tube. These deformations 341 serve as stops for locks.

La figure 6a montre que le logement d'arbre 29 comporte deux évidements latéraux 291 configurés pour recevoir les têtes de verrou respectives lorsque l'arbre de liaison 34 est inséré dans le logement d'arbre 29. En outre, le logement d'arbre 29 peut comporter deux rainures longitudinales de guidage 292 ménagées entre l'extrémité supérieure 24 et les évidements latéraux 291, permettant de guider l'insertion axiale de l'arbre de liaison 34 dans le logement d'arbre 29.The figure 6a shows that the shaft housing 29 has two lateral recesses 291 configured to receive the respective latch heads when the link shaft 34 is inserted into the shaft housing 29. In addition, the shaft housing 29 may have two longitudinal guiding grooves 292 formed between the upper end 24 and the lateral recesses 291, for guiding the axial insertion of the connecting shaft 34 into the shaft housing 29.

Lorsque l'arbre de liaison 34 est inséré dans le logement d'arbre 29, les verrous 4 se déploient en position de saillie, dans les évidements latéraux 291. Ils bloquent alors le déplacement axial de la sangle 31, retenant la dragonne 3 dans le corps 2.When the connecting shaft 34 is inserted in the shaft housing 29, the latches 4 extend in projecting position, in the lateral recesses 291. They then block the axial displacement of the strap 31, holding the strap 3 in the body 2.

Du fait que le logement d'arbre 29 débouche dans l'extrémité supérieure 24 du bâton, la dragonne 3 est maintenue bloquée dans le corps 2 lors de sollicitations transversales. En revanche, lors de l'exercice d'une traction axiale déterminée exercée sur la sangle 31, supérieure à la force de rappel des verrous 4, les têtes de verrou rentrent au moins partiellement dans le tube 34. Dans cette position rétractée, les verrous 4 sont désengagés du logement d'arbre 29 de sorte que la sangle 31 n'est plus retenue dans le corps 2. La dragonne 3 est alors désolidarisée du corps 2.Because the shaft housing 29 opens into the upper end 24 of the stick, the strap 3 is kept locked in the body 2 during transverse stresses. On the other hand, during the exercise of a determined axial traction exerted on the strap 31, greater than the restoring force of the bolts 4, the bolt heads enter at least partially into the tube 34. In this retracted position, the latches 4 are disengaged from the shaft housing 29 so that the strap 31 is no longer retained in the body 2. The strap 3 is then disengaged from the body 2.
