Description

Technical area

The present invention relates to the field of fixing a boot to a snowboard, generally called a “snowboard”.

Prior art

Traditionally, the equipment of the snowboard practitioner comprises a snowboard which is provided with bindings, and a pair of shoes specially adapted for the practice of this sport.

One of the problems in the practice of snowboarding is that the user must often take off and put on again, in particular to be able to take a ski lift or to cross flat terrain.

To take off and put on the snowboard, the user must generally bend down and sit in the snow in order to be able to unlock the fasteners of the bindings and release their shoes from the bindings.

Having to sit in the snow multiple times to put on or take off your shoes is restrictive and detracts from the pleasure of practicing this sliding sport.

To resolve this difficulty, there are specific shoes provided with a locking system which are designed to be fixed to a housing secured to the snowboard. A drawback of this solution is that it requires having a boot having a very specific structure, such a boot being generally more expensive than a standard snowboard boot.

The document DE9216831U1 discloses a mounting assembly according to the preamble of claim 1 including locking pins attached to the board. A binding spring, mounted on the binding of the boot, cooperates with the locking pins to block the binding relative to the board. In this assembly, the locking pins are arranged under the boot and also serve to position the binding relative to the board.

Disclosure of the invention

An object of the present invention is to provide a mounting assembly for securing a standard boot to a snowboard, making it possible to put on and take off simply and quickly without having to sit in the snow.

• un dispositif de fixation pour recevoir et maintenir une chaussure, le dispositif de fixation ayant une embase qui présente une direction longitudinale s'étendant entre une partie arrière et une partie avant;
• une platine, distincte du dispositif de fixation, et configurée pour être montée sur la planche à neige, la platine étant en outre configurée pour recevoir de manière amovible le dispositif de fixation ;
• un dispositif de verrouillage pour verrouiller le dispositif de fixation à la platine, le dispositif de verrouillage présentant une position verrouillée dans laquelle le dispositif de fixation est maintenu à la platine, et une position déverrouillée dans laquelle le dispositif de fixation peut être retiré de la platine ;
• un dispositif d'actionnement pour actionner le dispositif de verrouillage afin de l'amener en position déverrouillée ; et
• un dispositif de positionnement, distinct du dispositif de verrouillage, pour positionner par emboitement le dispositif de fixation par rapport à la platine.

The invention achieves its object by the fact that the assembly assembly according to claim 1 comprises:

• a binding device for receiving and holding a shoe, the binding device having a base which has a longitudinal direction extending between a rear portion and a front portion;
• a plate, separate from the binding device, and configured to be mounted on the snowboard, the plate being further configured to removably receive the binding device;
• a locking device for locking the fixing device to the stage, the locking device having a locked position in which the fixing device is held to the stage, and an unlocked position in which the fixing device can be removed from the stage ;
• an actuator for actuating the locking device to bring it to the unlocked position; and
• a positioning device, separate from the locking device, to position the fixing device by interlocking with respect to the plate.

It is understood that, in use, the user's shoe is engaged in the binding device, and all or part of the sole of the shoe comes to rest on the base. In a known manner, the binding device comprises straps or any other type of closure making it possible to hold the boot firmly in the binding device.

The plate is most often fixed once and for all on the snowboard and is generally not intended to be removed, except for possible position adjustment.

The user then brings his foot towards the snowboard in order to engage the binding device with the plate.

It is therefore understood that, in the locked position, the fixing device is positioned by interlocking with respect to the plate, the interlocking preferably being carried out by an engagement in a nesting direction substantially perpendicular to the plane of the base, c ' that is to say substantially perpendicular to the plane of the snowboard.

A function of the positioning device is to ensure that the fixation device is correctly positioned relative to the stage. Preferably, the positioning device makes it possible to avoid rotational play - in the plane of the snowboard - between the binding device and the plate, and therefore between the boot and the snowboard, whereby the user can control their snowboard efficiently and confidently.

This function is obtained by interlocking the fixing device with the plate.

The positioning device also makes it possible to block the binding device relative to the plate, in the plane of the snowboard.

The function of the locking device is to lock the binding device with respect to the plate in order to prevent the untimely disengagement of the binding device, which could cause the athlete to fall. Locking is achieved after the fastener and the plate are engaged together and positioned relative to each other by the positioning device.

The locking device is preferably designed to prevent a relative movement of the fixing device relative to the plate in a direction perpendicular to the base, and this when the fixing device is engaged by interlocking with the plate.

To take off the shoes, the user acts on the actuating device, which has the effect of actuating the locking device to bring it into the unlocked position. When the locking device is in the unlocked position, the binding device with the boot can be detached from the plate.

According to the invention, and unlike the prior art DE9216831U1 , the positioning device is separate from the locking device so that the positioning device does not participate in locking the fixing device to the plate. The positioning device is also remote from the locking device.

Advantageously, the positioning device comprises first positioning elements located on the plate and second positioning elements located on the fixing device, the first positioning elements being configured to be mounted by form cooperation with the second positioning elements.

It is therefore understood that the interlocking of the fixing device with the plate is obtained thanks to the form cooperation between the first and second positioning elements.

Preferably, the first positioning elements are arranged to extend transversely with respect to the base when the fixing device is mounted on the plate. This vertical extension makes it possible to block the pivoting movement of the binding device relative to the plate about an axis perpendicular to the plane of the snowboard.

Advantageously, the positioning device comprises four first positioning elements and four second positioning elements.

Advantageously, the base has a reception zone receiving the sole of the shoe, and the first positioning elements are arranged outside the reception zone so that the first positioning elements are located on either side of the shoe. .

According to an advantageous embodiment, the first positioning elements comprise studs, while the second positioning elements comprise orifices formed in the base, the studs engaging in the orifices when the fixing device is mounted on the plate. .

It is therefore understood that the interlocking is produced by engagement of the pads of the plate in the orifices of the base of the fixing device.

Preferably, the orifices are made at the four corners of the base, and the plate has four studs.

Again preferably, the studs are tapered. The maximum diameter of the studs is strictly greater than the diameter of the orifices so as to ensure that there is no play between the studs and the orifices when the fixing device is engaged with the plate.

Furthermore, the holes open out on either side of the thickness of the base, thanks to which the introduction of the studs has the effect of clearing the snow liable to accumulate in the orifices.
Preferably, the studs are arranged at the four corners of a body of the plate. Advantageously, the orifices are made in the base laterally on either side of the reception zone.

It is also understood that the fixing device is separate from the studs.

Preferably, to avoid slipping when the user has taken off their shoes, the lower face of the base is provided with crampons.

The fixing assembly according to the invention further comprises a spacer device arranged such that, when the fixing device is in the locked position, a space is defined between the base and the plate. In other words, the base is placed above and at a distance from a body of the plate.

One advantage is being able to lock the fixing device to the plate even in the presence of snow or ice in the space defined between the plate and the base. The invention therefore makes it possible to position and lock the binding device with the boot to the plate without having to constantly remove the snow liable to accumulate on the plate.

The space has a height, defined between the body of the plate and the underside of the base, of a few millimeters.

The spacing device may include a projecting part on the plate and / or on the base, making it possible to raise the base relative to the plate.

Preferably, the spacer device comprises a support device located on the plate, the base resting on the support device when the locking device is in the locked position.

The support device projects from the body of the plate in a direction transverse to the plane of the base.

According to a preferred embodiment, the support device comprises support members adjacent to the pads, the height of the support members being less than the height of the pads.

The base therefore comes to bear against the support members while being engaged in the studs. Another advantage of this configuration is to reduce the possible matting effects.

Preferably, the support members are more flexible than the pads.

Advantageously, the spacing device comprises four support devices arranged at the four corners of the plate, adjacent to the studs.

Advantageously, the assembly assembly according to the invention further comprises a return element for maintaining the locking device in the locked position when the actuating device is not actuated.

This return element preferably comprises a spring member which is arranged so as to bring the locking device into the locked position when the user no longer acts on the actuating device.

According to an advantageous embodiment, the locking device comprises at least a first housing as well as at least a first locking member shaped to cooperate with the first housing, in which the first locking member has a deployed position, in which said first locking member is engaged in the first housing when the locking device is in the locked position, and a retracted position in which the first locking member is disengaged from the first housing when the locking device is in the unlocked position, so that the fixing device can be removed from the plate.

Preferably, the first and locking member extend transversely with respect to the first retaining elements.

It is also understood that the return element is configured to keep the first locking member in the deployed position when the locking device is not actuated.

Preferably, the fixing device comprises the first locking member, while the plate comprises the first housing.

According to a preferred variant, the base has two lateral edges extending in the longitudinal direction, and in which, the first locking member, in deployed position, protrudes out of one of the two side edges in a direction transverse to the longitudinal direction.

Even more preferably, the plate comprises at least a first lateral ramp including the first housing in order to facilitate the guiding of the first locking member towards the first housing during the engagement of the fixing device with the plate.

Advantageously, the fixing device further comprises a second locking member, while the plate comprises a second housing for receiving the second locking member, and in which the first and second locking members are arranged on either side of the width of the base, while the first and second housings are arranged on either side of the width of the plate.

The plate preferably comprises a second ramp to facilitate guiding of the second locking member towards the second housing.

Advantageously, the actuating device comprises at least one elongate element connected to said locking device. The elongate element can be a rope or a cable. Pulling on the elongated element therefore has the effect of bringing the locking device into the unlocked position.

Preferably, the binding device further comprises a support portion disposed at the rear of the base and intended to bear against a rear part of the boot, and in which the elongated element cooperates with the portion d 'support. This support portion is generally called a “spoiler”.

One advantage is that the user can easily grasp the elongated element which is located at the level of the spoiler. Another advantage of this particular arrangement is that the elongated element does not interfere with the user while sliding.

According to an advantageous embodiment, the first and second locking members are mechanically coupled to one another so that the actuation of the elongated element has the effect of bringing the first and second locking members into position. retracted.

It is therefore understood that the fixing device can be removed very easily and quickly from the plate, in a single gesture of the user who, by pulling the elongated element towards him, simultaneously actuates the two locking members to bring them in the retracted position.

Preferably, to facilitate the grip of the actuation device by the user, the elongated element comprises at its end a gripping bulb.

The invention finally relates to a sliding device comprising a snowboard and at least one mounting assembly according to the invention, in which the plate is fixedly attached to the snowboard.

Detailed description of an embodiment

On the figure 1 , there is illustrated a sliding device 100 which comprises a snowboard 102 and a mounting assembly 10 according to the invention.

The mounting assembly 10 is arranged to secure a boot (not shown here) to the snowboard 102.

To do this, and in accordance with the present invention, the mounting assembly 10 comprises a binding device 12 for receiving and holding the boot, and a plate 14 , separate from the binding device 12 , which is configured to be mounted on the boot. snowboard 102. As will be explained in more detail below, the plate is further configured to removably receive the binding device 12.

As can be seen on the figure 1 , the plate 14 is fixedly fixed to the snowboard 102. The position of the plate on the upper surface 102a of the snowboard 102 can be adjusted, in known manner, by suitable means, for example an adjustment disc (not shown here).

In this example, the fixing of the plate to the snowboard is carried out using screws which engage in the thickness of the snowboard 102 without however crossing it.

On the figure 2 , the mounting assembly 10 is illustrated in a configuration in which the fixing device 12 is engaged with the plate 14.

The fixing device 12 includes a base 16 which has a longitudinal direction L extending between a rear portion 12a and a front portion 12 b of the fixing device 12. The base 16 has a substantially planar shape and has a receiving area 17 , illustrated in figure 7 , to receive the sole of the shoe. This reception area 17 is substantially flat and may include front and rear pads as illustrated in particular in figure 7 .

In a known manner, the fixing device 12 furthermore comprises a support portion 18 , generally called a "spoiler" which is disposed at the rear of the base 16. This support portion 18 is intended to come to bear against a rear part of the boot when the latter is mounted in the binding device 12. In this example, the support portion 18 comprises a bracket 20 which is integral with the base, and a support element 22 which is mounted pivotally relative to the stirrup 20 , the support element being the part which bears against the rear part of the boot.

To ensure the maintenance of the boot, the binding device 12 furthermore comprises, in known manner, a front strap 22 and a rear strap 24 , shown diagrammatically on the figure 1 .

To facilitate understanding of the invention, these front and rear straps 22 , 24 have not been illustrated in the other figures.

As shown in figure 7 , the fixing device 12 comprises studs 27 which protrude from the underside of the base 16. These studs prevent the user from slipping when walking with the fixing device.

According to the invention, the fixing device 12 is arranged to be removably mounted to the plate 14 , the latter being for its part fixed integrally to the snowboard 102.

The fixing device 12 can be locked and unlocked with respect to the plate, this locking having the aim of preventing the fixing device from inadvertently disengaging from the plate 14 during the descent of a track.

To ensure the locking of the fixing device 12 to the plate 14 , this locking, the mounting assembly 10 further comprises a locking device 30 , which has a locked position in which the locking device fixing 12 is held on plate 14. In other words, in the locked position, the fixing device 12 cannot be separated from said plate.

As explained above, to allow the user to take their shoes off easily and quickly, that is to say to be able to detach their boot from the snowboard, the locking device further comprises an unlocked position in which the device fixing 12 can be disengaged from the plate 14. It is therefore understood that, in the unlocked position, the assembly formed by the binding device and the boot can be separated from the plate 14.

To do this, the mounting assembly 10 further comprises an actuating device 39 which enables the locking device 30 to be actuated in order to bring it into the unlocked position.

The locking device 30 will now be described in more detail .

With reference to the figure 4 , we see that the plate 14 comprises a first ramp 32 and a second ramp 34 , opposite the first ramp 32 , the first and second ramps 32 , 34 being located on either side of the width of the plate and being arranged to be arranged on either side of the width of the base 16 when the fixing device 12 is engaged with the plate 14.

The locking device 30 comprises a first housing 36 which is formed under the first guide ramp 32 , and a second housing 38 , formed under the second guide ramp 34. The locking device 30 also comprises at least a first locking member. locking 40 , here having the shape of a pin, shaped to cooperate with the first housing 36. The locking device 30 furthermore comprises a second locking member 42 also having the shape of a pin, shaped to cooperate with the second accommodation 38.

As can be seen on the figure 4 , the first and second locking members 40 , 42 are arranged on either side of the width of the base 16. Furthermore, the first and second housings 36 , 38 are for their part arranged on either side the width of the plate 14.
The base 16 has two side edges 16 a, 16 b extending in the longitudinal direction, and in which, the first locking member, in the deployed position, projects out of one of the two side edges in a transverse direction to the longitudinal direction L.

With reference to figures 2 and 5 , it can be seen that the first locking member 40 has a deployed position in which said first locking member is engaged in the first housing 36 when the locking device is in the locked position.

Similarly, the second locking member 42 has a deployed position in which said second locking member 42 is engaged in the second housing 38 when the locking device is in the locked position.

In this example, it is understood that the first and second locking members 40, 42 extend perpendicularly to the longitudinal direction L of the fixing device.

With reference to figures 3 and 6 it is observed that the first locking member 40 has a retracted position in which the first locking member 40 is disengaged from the first housing 36 when the locking device is in the unlocked position.

Likewise, the second locking member 42 has a retracted position in which the second locking member is disengaged from the second housing 38 when the locking device is in the unlocked position.

Consequently, when the first and second locking members 40, 42 are in the retracted position, the fixing device can be detached from the plate.

Using the figures 5 and 6 , it is understood that the passage between the deployed and retracted position of the first locking member 40 is effected by a translation along a first axis A which is perpendicular to the longitudinal direction L. Similarly, the second locking member 42 passes from the deployed position to the retracted position by translation along a second axis B which is parallel to the first axis A.

In this example, the first and second axes A , B are distant from each other, which means that the first and second locking members are not coaxial. The advantage is to prevent the fixing device from pivoting around one or other of the first and second locking members, relative to the plate, when the locking device is in the locked position. One advantage is to improve the stability of the fixing device 12.

With reference to figures 5 and 6 , it can be seen that, in this nonlimiting example, the first and second locking members 40, 42 are mechanically coupled to one another using a carousel 44 which is rotatable about a perpendicular X axis to a plane P passing through the first and second axes A , B.

The carousel 44 is arranged such that, the setting in rotation of the carousel 44 around the axis X causes the displacement in translation along the first axis A of the first locking member 40 and the concomitant displacement in translation, in an opposite direction , of the second locking member 42 along the second axis B.

The actuating device 39 , which makes it possible to actuate the locking device 30 to bring it into the unlocked position, in this example comprises an elongated element 50 , such as a small diameter metal cable, which is connected to the locking device. 30. the elongate locking member 50 includes a first end portion 50 a which is fixed to the rotating carousel 44. the elongate member 50 is also engaged in a sheath 52 which extends outwardly between the base 16 and the support portion 18. More precisely, in this example, the sleeve 52 is engaged in the thickness of the support element 22 and protrudes behind the support element. The elongated element 50 also comprises a second end 50 b, opposite the first end 50 a, which is connected to a gripping bulb 54. It is understood that when the user pulls on the gripping bulb 54 , this causes traction. on the elongated element 50 , as a consequence of which the carousel 44 pivots around the X axis in the direction of clockwise, which causes the translational movement of the first and second locking members 40 , 42 of their extended position to their retracted position.

Using the figures 5 and 6 it can be seen that the mounting assembly 10 further comprises a return element 60 , comprising a first return spring 62 and second spring 64 , for maintaining or returning the locking device to the locked position when the actuating device is not not actuated. In this example, the first return spring 62 of the return element 60 is configured to maintain or return the first locking member 40 to the deployed position when the locking device is not actuated. Similarly, the second return spring 62 of the return element 60 is configured to hold or return the second locking member 42 to the deployed position when the locking device is not actuated.

In other words, when the user lets go of the gripping bulb 54 , the first and second return springs 62 , 64 act on the first and second locking members 40 , 42 to bring them into the deployed position.

The coupling of the fixing device with the plate is done as follows. The user, having previously fixed the binding device to his shoe, engages the binding device with the plate so that the first and second locking members come into contact with the first and second guide ramps. The user pushes the fastening device towards the body of the plate, which has the effect of slightly retracting the pins. Once the pins are opposite the first and second housings, the action of the first and second springs has the effect of engaging the first and second guide members in the first and second housings, which causes locking.

According to another advantageous aspect of the invention, the assembly 10 further comprises a positioning device 70 , which is distinct from the locking device, and which has the function of positioning by interlocking the fixing device 12 relative to the plate 14. The positioning device 70 comprises first positioning elements 72 located on the plate and second positioning elements 74 located on the fixing device. The positioning device 70 is also remote from the locking device.

Using the figures 2 and 4 , it will be understood that the first positioning elements 72 are configured to be mounted by form cooperation with the second positioning elements 74.

In the embodiment illustrated here, the first positioning elements 72 are arranged to extend transversely with respect to the base 16 when the fixing device is mounted to the plate. By virtue of the positioning device, the play between the fixing device and the plate in the locked position is eliminated, at the very least it is significantly reduced. In particular, the positioning device has the effect of preventing rotation of the fixing device relative to the plate in the aforementioned plane P. In this example, the positioning by interlocking takes place in a nested direction Y which transverse to the longitudinal direction L on the one hand and to the first and second axes A , B on the other hand. In other words, the interlocking direction Y is transverse to the plane of the upper surface 102 a of the snowboard.

In this example, the positioning device is arranged such that the locking of the fixing device relative to the plate and the positioning by interlocking take place at the same time.

It is therefore understood that the function of the locking device is to lock the fixing device relative to the plate, that is to say to prevent a separation between the fixing device and the plate, while the positioning device Its function is to eliminate the relative play between the fixing device and the plate when the fixing device is engaged and locked with the plate.

In this exemplary embodiment, the first positioning elements 72 are four in number and comprise frustoconical studs 73 which project from a body 75 of the plate. It is understood that the frustoconical studs 73 protrude while extending in the direction of interlocking Y.

As can also be seen on the figure 4 , the positioning device comprises four studs 73 which are arranged at the four corners of the body 75 of the plate 14.

The second positioning elements are four in number and comprise orifices 77 which are formed in the base 16, as is clearly visible on the figures 4 and 7 . The orifices 77 are arranged laterally on either side of the reception zone 17, so as to flank the boot. It is understood that the pads 73 and the orifices 77 are shaped so that the pads 73 engage in the orifices 77 when the fixing device is mounted on the plate. It is also understood that the orifices 77 are separate from the first and second housings 36, 38.

It is also noted that the orifices 77 pass through the thickness of the base 16. The advantage is that when the fixing device is engaged with the plate, the engagement of the studs in the orifices 77 has the effect of '' evacuate the snow likely to accumulate in the openings 77.

The mounting assembly 10 further comprises a spacer 81 which is arranged such that, when the fixing device is in the locked position, a space E is defined between the base 16 and the plate 14. The space E is substantially empty so that the fixing device 12 can be engaged and locked with the plate 14 even in the presence of snow or ice on the body of the plate 75, since the thickness of snow on the body 75 n 'is not greater than the height h of the space E. In this example, the height h is of the order of four millimeters. In this exemplary embodiment, the spacer device 80 comprises at least one support device 82 located on the plate 14, the base 16 resting on the support device 82 when the locking device is in the locked position, and the fixing device is positioned relative to the plate thanks to the positioning device, as can be understood with the aid of the figure 8 .

In this example, the spacer device 80 comprises four support devices 82 which are arranged at the four corners of the body 75 of the plate 14, adjacent to the stud 73. It is also noted that the height of the support devices 82 is less than the height of the tapered studs 73.
