Abstract

A pole, for use in skiing or other sport, of the type that includes a grip handle at its upper end, the handle including a support extending from its side wall and adapted to cooperate with the thumb of a user, so as to constitute an additional mechanism for the axial transmission of forces, by the thumb, when the hand is closed on the handle of the pole.

Description

SKI STICK

The present invention relates to a pole and in particular a ski pole of the type comprising at its upper end a grip handle.

In ski poles this handle is generally provided with a closed loop strap called wrist strap, which is integral with said handle and in which the skier passes his hand in order to avoid losing his stick when he unexpectedly releases the closure of his hand on the handle. The wrist strap also has the function of allowing a better transmission of forces, in particular in the support phase on the pole, either for turns in alpine skiing, or for stride or the practice of skating steps in cross-country skiing, or for the practice of inline skating or ice skating but also for the practice of sport walking.

To be truly effective, a wrist strap must therefore be passed so as to partially encircle the wrist, the two end strands of the loop connected to the handle passing through the palm of the hand.

However, the majority of skiers, and in particular beginners, position the wrist strap badly, which completely cancels the effectiveness and the effect of transmission of the efforts thereof. In addition, in order to improve the quality of the impulse on the pole, the poles used in particular for the practice of cross-country skiing include a wrist strap which is traditionally connected to the rear face of the handle. According to this arrangement, the hand is supported on the wrist strap, on the internal side, at the level of the first phalanx of the thumb on the thumb muscle. However, this support performed on a muscle is not very effective and can be painful for said muscle.

It is for this reason that it has already been proposed to integrate the wrist strap into a glove or the like slipping on the hand of a skier, and to be able to connect it to the handle by a removable connection system consisting of additional means arranged on the one hand on said handle, and on the other hand on the strap integrated in the glove.

Such a device has been devised and described in invention patent no. 2,634,388 filed by the plaintiff, and which allows the glove, or an adequate envelope / sheath, fitted with a connecting element to be put on only to the handle of the stick, to have an adequate connection between the hand of the user and said stick, namely a connection with transmission of forces.

Such an improvement therefore makes it possible to significantly improve the transmission of forces.

The problem of transmission of forces also exists on ski poles or the like without a wrist strap.

The present invention therefore aims to further improve the existing handles and to propose an improvement allowing an optimized transmission of forces between the hand of the skier and the handle of the pole, in particular ski pole, whether or not the latter is provided with a wrist strap, and that it is integrated into the stick or the glove. It also aims to improve the grip and the contact between the hand and the handle of the stick by ensuring a frank and powerful contact.

To this end, the invention relates to a stick of the type comprising at its upper end a grip handle with or without a closed loop strap or strap, or integral with said handle, either integrated into a glove or the like slipping on the hand of a user and connected to the handle by a removable connection system, consisting of complementary fixing means arranged on the one hand on said handle and d on the other hand on the wrist strap integrated into the glove, characterized in that said handle comprises a fulcrum, protruding from its side wall and able to cooperate in abutment with the thumb of a user, so as to constitute a means additional axial force transmission, by said thumb. Such a construction makes it possible to notably increase the power transmitted during the pushing on a stick by also using the pushing force exerted by the thumb. Indeed, the support, being located at the level of the second phalanx of the thumb, optimizes the power of the support.

In a first embodiment, the support is fixed on the handle of the stick.

In a second embodiment, the support is substantially mobile in rotation relative to the handle in order to best follow the movements of the hand during the impulse phase on the stick.

The present invention also relates to the characteristics which will emerge during the description which follows, and which should be considered in isolation or according to all their possible technical combinations.

This description given by way of nonlimiting example will make it easier to understand how the invention can be produced with reference to the attached drawings in which:

Figure 9 schematically illustrates a side view of a stick handle according to a second variant of the second embodiment.

FIG. 10 schematically illustrates a side view of a baton handle according to a third variant of the second embodiment. Figure 1 shows an example of application of the invention to a pole, in this case ski pole 1 which has a handle 2, object of the invention, intended to be grasped by the hand of a user on which a glove 3 was preferably put on.

In general, said handle 2 is in the form of an essentially cylindrical element comprising a peripheral wall 2a. The handle 2 has a fulcrum 4, emerging laterally from its side wall 2a and capable of cooperating in abutment with the thumb 5 of the user, so as to constitute an additional means of axial force transmission, by said thumb 5 , for a natural position thereof when the hand is closed on the handle 2 of the stick 1. By fulcrum or support is meant here an area not necessarily punctual intended to serve as support for the thumb.

More specifically, the fulcrum 4 of thumb 5 extends in projection substantially perpendicular to the longitudinal axis XX 'of the handle 2, from an intermediate zone of the side wall 2a of the handle 2, at the like a crutch.

This fulcrum 4 of thumb 5 is shaped on its upper part substantially in rounded tiles, the curve of which is directed upwards so as to conform to the shape of thumb 5 when the hand is closed on the handle 2 during practice. Sport.

As the figures clearly show, the fulcrum 4 is also inclined angularly towards the rear relative to the longitudinal axis XX ′ of the handle 2, so as to perfect the ergonomics of the latter at the level of the thumb 5, when the hand is closed.

According to another characteristic of the invention, an area B of the side wall 2a of the handle 2, substantially opposite to that A from which the support 4 of the thumb 5 emerges, has a convexity 6 of shape and dimensions provided so to be housed ergonomically in the palm of the user's hand when the thumb 5 is in contact with its fulcrum 4 for a closed position of the hand around the handle 2.

The handle 2 is ergonomically shaped so as to be intended for a right hand or a left hand of the skier, the fulcrum 4 being located, seen from the skier, on the left, and the convexity 6 on the right, for one hand right.

Conversely, for a left handle, the fulcrum 4 will be located on the right, always seen from the skier, and the convexity 6 will be located on the left.

In this case, the figures shown relate to a right hand grip.

According to a particular application of the invention to the practice of skiing shown in the figures, a wrist strap 7 is integrated into the glove 3 intended to be put on the hand of a skier, and connected to the handle 2 by a removable connection system consisting of complementary means 8, 9 arranged on the one hand on said handle 2, and on the other hand on the wrist strap 7 integrated into the glove 3.

In this case, one of these complementary means 8 located on the handle 2 is produced in an area C in a direction substantially perpendicular to those A and B in which the fulcrum 4 of the thumb 5 and the convexity 6 are obtained. of the handle 2, that is to say a zone C which is directed towards the arm of the user when he grasps the stick 1. For documentary purposes, it should be noted that a wrist strap of this type integrated into a glove is described in French patent application No. 2,634,388 filed by the applicant.

More specifically, the complementary connecting means 8 of the handle 2 is raised relative to the support plane P defined by the fulcrum 4 of the thumb 5, so as to be substantially at the level of the mutual rotation zone of the hand relative to the handle / ski pole, so as to avoid phenomena such as blisters due to the relative sliding of these elements during their mutual rotation and allow optimal transmission of forces.

Tests have shown that a distance D of about 20 mm between the upper support plane P of the support point 4 and the axis 8a of the complementary connecting means 8 of the handle 2 constitutes an optimum distance depending on the different users and in fact offers the skier a preset position of the elements together, namely wrist strap 7, connecting means 8 and thumb support point 4.

According to a preferred embodiment, the complementary connecting means 8 of the handle 2 with that intended to cooperate with the connecting means 9 of a wrist strap 7 is constituted by an immobilizing element 10 able to be moved in a housing 11 substantially horizontal recessed in the handle 2 and into which is likely to be introduced a free end 12 of the strap 7 carrying the complementary means 9 to cooperate in fixing with said element 10.

Said immobilizing element 10 is constituted by a slide capable of being driven in vertical translation in a corresponding housing 13, of substantially vertical axis, produced in an upper part of the handle 2 and one end of which opens into the housing 11. One end of the slider 10 forms a point 10a capable of being engaged in a corresponding hole 9 of the free end 12 of the wrist strap 7 which constitutes the complementary means of connection thereof, while the other end 10b of the slider 10 , is directed opposite to the upper part of the handle 2, to constitute a gripping grip of said slide 10 in a direction of immobilization or release of the wrist strap 7.

In fact, the housing 11 extends transversely inside the handle 2 and is of substantially identical size and shape at the end 12 of the wrist strap 7 which must be introduced therein for its immobilization.

The slide 10 also has, near its upper end portion 10b, a hole 10c intended for the insertion of a flexible gripping element 14, which is formed by a link or a strap, so as not to create an element rigid protruding dangerous during skiing, the slide 10 can then be fully retracted in the locking position of the wrist strap 7.

The slide 10 also includes an oblong slot 10d, the upper and lower ends of which constitute stops in one direction of sliding or in the other, relative to a fixed pin 15 passing through the handle. Figures 4 to 10 show a grip handle 2 mounted on a stick 1 which is intended more specifically for the practice of cross-country skiing, inline skating, ice skating and sport walking, and more generally for all practices sports in which the user takes support on the stick, when the hand is closed on the handle 2, but also when the hand is not closed on the handle 2. This last position corresponds to the end of support on the stick 1 when said stick 1 is positioned behind the user. To obtain this result, the fulcrum 4 is mounted substantially pivoting relative to the handle 2.

In FIG. 4, the fulcrum 4 is integral with a pendulum 100 and is positioned at the lower end 100a of said pendulum 100. The pendulum 100 is fixed, at its upper end 100b, to the lateral face 2a of the handle 2. In addition, the handle 2 comprises a pivoting hooking means 52 which keeps the pendulum 100 pivoting on the handle 2 about an axis A which is substantially perpendicular to the lateral part 2a of the handle 2. Thus, the pendulum 100 pivots towards the rear of the handle 2 to move away from its position along the side wall 2a of the handle 2. So that the fulcrum 4 remains permanently in contact with the thumb of hand during the entire impulse phase on the stick 1, the axis A is located in the upper part 50 of the handle 2, ie above the fulcrum 4, when the balance 100 is in position substantially the along the side wall 2a of the handle 2. Physiological tests e t comfort of the support have shown that the optimal distance between the support point 4 and the axis A along the balance 100 was about 20 mm.

So that the balance 100 does not constitute a prominence relative to the handle 2, the handle 2 comprises, at its lateral face 2a, a recess 101 complementary to the balance 100 when the latter is in position along the lateral face 2a. The reinforcement depth 101 is substantially equal to the thickness of the pendulum 100 in order to obtain a substantially continuous surface on the lateral face 2a when the hand is closed on the handle 2.

The pendulum 100 and the fulcrum 4 may be made of thermoplastic material, in particular of ABS or polyethylene type, about 1 to 3 mm thick at the pendulum 100. In addition, the pivoting attachment means 52 may advantageously consist of a screw which is mounted substantially perpendicular in the lateral face 2a of the handle 2.

Of course, the handle 2 can be equipped with a conventional wrist strap not shown or else with a wrist strap integrated into the glove as described above. In this case, the attachment of the wrist strap to the handle 2 will advantageously be positioned in elevation at the altitude defined by the axis A.

Figures 5 to 10 show variants of the second embodiment of the invention in which the fulcrum 4 is produced by a wrist strap 51 which equips the handle 2. The fulcrum 4 obtained is of flexible type therefore a little less efficient than the rigid supports previously described. However, these variants have the advantage of being much less ,

costly to implement and to adapt to the specific morphology of the hand of each user by making it possible to vary the distance between the fulcrum 4 and the axis A of rotation.

FIG. 5 represents a front view of the handle 2 according to a first variant in which the wrist strap 51 is pivotally mounted relative to the handle 2 about an axis A which is oriented substantially perpendicular to the side wall 2a of the handle 2. The strap 51 comprises at its two ends 105, 106, a contact zone 107 such as a rivet capable of cooperating with the hooking means 52 of the handle 2. The strap 51 extends, on the one hand, from the end 105 to form an internal portion 65, and on the other hand, from the end 106 to form an external portion 66. The two portions 65, 66, are connected by an upper zone 64 which is located substantially at the top of the strap 51, positioned substantially between the top 107 of the handle 2 and the axis A, and positioned at the rear of the handle 2. The internal portion 65 constitutes a loop which is located on the side wall 2a and comprises, in its part the lower, the fulcrum 4 intended to cooperate with the thumb passing under the thumb. Similarly, the outer portion 66 forms a loop, located on the outer side wall 2b, and which comprises in its lower part a support support 104 intended to cooperate with the edge of the palm of the hand while passing under said edge.

Figures 6a, 6b, detail the internal side of the handle 2 equipped with the strap 51, as previously described in Figure 5, with the right hand M inserted in the strap 51. Figure 6a where the hand M is closed on the handle 2 represents the start of the pulse phase on the stick 1. Figure 6b represents the end of the pulse phase on the stick 1 where the hand M is not closed on the handle 2, but is always resting on the stick 1 by means of the wrist strap 51. The parts of the wrist strap 51 which are hidden by the hand M or the thumb 5 are shown in broken lines.

In FIG. 6a, the handle 2 comprises a strap 51 which cooperates with the thumb 5 so as to constitute the fulcrum 4. The strap 51, which is pivotally mounted on the handle 2 around the axis A, comprises a internal branch 70 which extends downward along the side wall 2a of the handle 2 from the end 105, substantially to the fulcrum 4. Thus, the fulcrum 4 is located at the second phalanx 71, and / or its articulation 73 which joins the first phalanx 72 to the second phalanx 71 of the thumb 5, at the location where the wrist strap 51 partially surrounds the thumb 5. The support of the hand M on the stick 1 is completed by the external portion 66 of the wrist strap 51 which passes at the level of the support support 104 under the edge 5 'of the palm of the hand M.

The wrist strap 51 and its internal branch 70 are substantially aligned with the handle 2 of the stick 1, even if the internal branch 70 has a residual angle αo relative to the axial axis of the stick 1. Tests have shown that this residual angle αo usually has a value between 0 ° and 10 ° when the hand M is closed on the handle 2.

In FIG. 6b, the hand M is substantially positioned along the axis B of the stick 1. As the wrist strap 51 is pivotally mounted relative to the handle 2, the wrist strap 51 can follow the movement of the hand M while remaining in close contact with the latter. To obtain this result, the outer portion 66 of the strap 51 which surrounds the edge 5 ′ of the palm of the hand M, will advantageously have a flexible character. Thus, the wrist strap 51 pivots according to the angle α by a value approximately between 30 ° and 50 °, and the wrist strap 51 is deformed at the level of the external portion 66 in order to be offset with respect to the internal branch 70 of a angle β with a value approximately between 40 ° and 60 °. Compliance with this constructive arrangement makes it possible to obtain a fulcrum 4, at the level of the internal portion 65 which surrounds the thumb 5 substantially at the level of the second phalanx 71, which deforms the deformations of the palm of the main M. The wrist strap 51 can advantageously be made as a strap. Of course, the wrist strap 51 can be made of rigid or semi-rigid material of the thermoplastic material type, the rotation then taking place only by the axis A.

FIG. 6b also illustrates another advantage of the present invention as regards the position of the hand M relative to the stick 1. In fact, the hand M is positioned very high on the stick 1 unlike the other existing and known strap systems, which allows to increase the forward movement obtained by the user relative to the base of the stick 1 during the pulse phase.

Figure 7 shows an improvement of the wrist strap 51 previously described. The gripping handle 2, here illustrated from above, comprises a hooking means 67 intended to cooperate by a link 68 with the upper zone 64 of the wrist strap 51. The hooking means 67 can be in particular, but not limitative, a vertical slot located on the rear face 2C and in the upper part of the handle 2. This hooking means 67 corresponds in particular to the known attachment of the conventional strap on the stick handle. Similarly, the link 68, which is fixed by its end 68a by means of hook 67, is connected at its other end 68b to the upper zone 64 of the wrist strap 51. The fixing of the link 68 on the wrist strap 51 can be fixed such as a seam, or removable and repositionable such as a hook-and-loop fastening, which allows adjustment of the distance between the top of the strap 51 and the handle 2. The link 68 may advantageously have a character elastic, and in particular be made in a nonlimiting manner in elastic strap in order to adapt to the deformations of the hand M during the impulse movement of the user on the stick 1.

FIG. 8 represents another variant of construction of the wrist strap 51 previously described which is here illustrated to cooperate with the user's left hand. The strap 51 comprises a connecting piece 75 which connects at least one of the portions 65, 66 of the strap 51 to its upper zone 64. In the preferred embodiment shown here, the connecting piece 75 is fixed, at the level of 'one of its ends 75a, by suitable means such as seams 152, 153, respectively to the inner 65 and outer 66 portions. The connecting piece 75 will advantageously be positioned between the adjacent edges of the two parts 65, 66, and most possible near handle 2 of the stick. The other end 75b of the piece of connection 75 comprises a removable and repositionable fixing means 150, in particular of the hook-and-loop type, which cooperates with the upper zone 64 of the wrist strap 51. The end 75b of the connection piece 75 can advantageously pass through a tunnel 151, fixed on the upper zone 64 of the wrist strap 51, such that said tunnel 151 comprises attachment means complementary to the fixing means 150. Thus, the end 75b is kept fixed in the tunnel 151 according to the path illustrated by the arrow shown on Figure 8 interrupted.

The variant embodiments of the wrist strap 51, which are illustrated in FIGS. 7 and 8, make it possible to maintain the upper zone 64 of the wrist strap 51 in a position close to the upper part 50 of the handle 2. They provide the wrist strap 51 with a position optimal on the user's hand M, in particular so that the internal portion 65 surrounds the thumb 5 well at its second phalanx 71 and / or the joint 73. In fact, in the absence of connecting piece 75 or link 68, the wrist strap 51 risks, during numerous impulse phases, to slide progressively, on the hand M, towards the rear while moving away from the handle 2.

FIG. 9 represents a wrist strap 51 associated with a handle 2 which is intended to cooperate with the user's left hand. The wrist strap 51 is mounted substantially pivotally relative to the grip handle 2. However, the pivoting is not obtained by a pivoting fixing means as in the embodiments previously described. The pivoting is obtained by the deformation of a flexible part of the strap 51. To obtain this result, the handle 2 comprises on its upper face 60 a hooking means 61 which cooperates with at least one attachment zone 62 of the wrist strap 51. In addition, the wrist strap 51 comprises at least one flexible element 63, which is located near the attachment zone 62, which makes it possible to pivot the wrist strap 51. The hooking means 61 can be made by means of a screw and the attachment zone 62 may be symmetrical in order to extend on either side of the handle 2, by the internal 65 and external 66 portions. The wrist strap 51 may advantageously be fixed to the handle 2 by a complementary hooking means 61 'positioned in the upper zone 50 of the handle 2 and on its rear face 2c.

In the preferred embodiment and illustrated in FIG. 9, the wrist strap 51 comprises an adjustment means in order to adapt to the morphology, in particular to the volume and the perimeter of the user's hand. The adjustment means will advantageously be positioned near the upper zone 64 in order to simultaneously adjust the length of the internal 65 and external 66 portion of the wrist strap 51. The external portion 66 of the wrist strap 51 is extended by a tab 156 which passes through the reference 155 then returns to the external portion 66. The tab 156 is fixed to the external portion 66 by removable fixing means, in particular of the self-gripping type. Of course, other known adjustment systems are in accordance with the invention and this improvement applies to all the embodiments and variants of the present invention.

FIG. 10 represents a wrist strap 51 associated with a handle 2 intended to cooperate with the right hand of the user. The pivoting of the strap 51 is also obtained by a deformation of said strap 51. To obtain this result, the handle 2 comprises, on its front face 2d and in the upper part 50, a hooking means 54 which cooperates with at least one attachment zone 56 of the strap 51. In addition, the wrist strap 51 comprises at least one flexible element 55 which is located near the attachment zone 56, and which makes it possible to pivot the wrist strap 51. The flexible element 55 may advantageously consist of the hand strap 51 if the latter consists of a flexible element such as a strap. Likewise, the attachment of the wrist strap 51 may be supplemented by additional hooking means 54 ′ situated on the rear face 2c and in the upper part 50 of the handle 2.

The present invention also relates to the grip handle as such.

Of course, the present invention is not limited to the embodiments described above, which are given for information only, but encompasses all similar or equivalent embodiments.
