The state of the art reflected in these documents shows that it is limited to a single closing position of the snowboard binding. The disadvantage which This is particularly noticeable when snow accumulates between the pedal and the base. In this circumstance, which is very common in practice, it may prove impossible to pivot the support shell into the closed position and therefore to engage the elastic return lever with the locking means.

Statement of the invention

One of the aims of the invention is thus to modify the type of snowboard binding described above, to guarantee the blocking of the support shell in the closed position, in all circumstances.

To this end, the invention relates to a snowboard binding in accordance with the introductory description, characterized in that it comprises a lug received in a fork of the notched means or the lever to rotate the locking means or the lever, by unclicking the lever from one of the notches and by snapping it into the other notch during putting on.

Thus, the snowboard binding according to the invention allows the lever, by driving the fork by means of the lug, to snap into different closing positions during putting on, determined by the different notches of the locking means.

The lug can be fixed in the base, the support shell or the pedal.

According to the first embodiment, the notched means comprises a wheel provided with a notch forming the fork receiving the lug. The wheel can be movable in rotation relative to the support shell and the lug, fixed in the base. Alternatively, the wheel can be movable relative to the base and the lug, fixed in the support shell or in the pedal.

According to a second embodiment, the lever comprises a first arm movable in rotation relative to the support shell and a second arm, articulated to the first arm and snapped with the notched means, which is fixed in the support shell, the first arm of the lever provided with a notch forming the fork, opposite the second arm and the lug being fixed in the base.

According to an alternative embodiment of the first mode, the lug is carried by a hull side of the support hull.

According to an alternative embodiment of the second mode, the first arm of the lever is an arch articulated to two hull sides of the support hull.

These variants are more particularly advantageous when a hull bottom of the support shell or the base comprises a hinge bearing, mounted around the axis of rotation of the support shell relative to the base, serving as a guide stop in any position of the support shell, between the open position and the closing positions, when putting on and taking off shoes.

Way(s) of carrying out the invention

A snowboard binding, illustrated by one of the figures 1 to 7 , comprises a base 1, a support shell 3, a pedal 5 and a strap 7. The support shell 3 is movable around the axis of rotation A1 carried by the base 1. The pedal 5 and the strap 7 are provided to control the support shell 3 respectively when putting on and taking off the shoe, between an open position and a closed position. The support shell 3 comprises a shell bottom 9 and two shell sides 11. The pedal 5 is articulated to the two shell sides 11 around an axis of rotation A2. The strap 7 is articulated to the support shell 3 around an axis of rotation A3. A means 15, 16 is provided to block the rotation of the support shell 3 relative to the base 1 in the closed position, against an elastic return lever 13, 13a, 13b. This means 15, 16 comprises two or more snap-in notches 17.

The elastic return lever includes an operating arm 12 to be manually released in order to unlock the support shell from the closed position and allow the shoe to be removed.

According to the invention, the snowboard binding comprises a lug 21 received in a fork 20 of the means 15, 16 with notches 17 or of the lever 13, 13a, 13b to drive the means with notches or the rotating lever, by unclicking the lever from one of the notches 17 and clicking with the other notch 17 during putting on.

THE figures 1 to 4 illustrate a first embodiment, in which the means 15 with notches 17 comprises a cam or a wheel provided with a notch 23 forming the fork 20 receiving the lug 21.

In the example of the Figure 1, 2 Or 3 , the wheel 15 is carried by the base 1 around an axis of rotation A5 to be controlled by the lug 21, carried, Figure 1 , by two lateral arms 19 themselves carrying the pedal 5 or carried, Figure 2 Or 3 , by the hull sides 11, in this case following the axis A3 of articulation of the strap 7.

The elastic return lever 13 is movable relative to the base 1 around an axis of rotation A4 and provided with a notch 25 for snapping into the notches 17 of the wheel 15. The elastic return of the lever 13, obtained by a means known per se and not shown in the figures, for example a spring, allows it to be in abutment against the wheel 15 while the latter is driven in rotation by the lug 21.

The driving of the wheel 15 by the lug 21 allows, while the support shell 3 is driven in rotation around the axis A1 by the pedal 5 during fitting, the lever 13 to be released from a notch 17 to engage with the following notch, so that the wheel 15 orders the succession of the different closing positions according to the succession of the notches.

In the example of the Figure 4 , the wheel 15 is rotatable relative to the hull sides 11 and the lug 21 is fixed to the base 1. The lever 13 with elastic return is also rotatable relative to the hull sides 11. Note that, in this exemplary embodiment, the lateral arms 19 of the pedal 5 are only articulated to the support shell 3, whereas they are also articulated to the base 1 in the example of 1a Figure 3 .

THE Figures 5 and 6 illustrate a second embodiment, in which the lever 13 comprises a first arm 13a movable relative to the support shell 3 around an axis of rotation A4 and a second arm 13b, articulated to the first arm 13a around an axis of rotation A6 and snapped with the means 16 with notches 17, which is fixed to the support shell 3. The first arm 13a is provided with a notch 23 forming the fork, opposite the second arm 13b while the lug 21 is fixed in the base 1. The driving of the first arm 13a by the lug 21 allows the second arm 13b, while the support shell 3 is driven in rotation around the axis A1 by the pedal 5 during fitting, to unclip from a notch 17 to snap into the next notch, so that means 16 orders the succession of the different closing positions according to the succession of the notches.

It should be noted that any notch of the means 16 forms, with the articulation of the first arm to the support shell and the articulation of the second arm to the first arm, a triangle Locking T, in any closing position of the support shell. The Figure 5 illustrates a closing position determined by a first notch, while in the Figure 6 , the closing position is determined by a final notch.

THE figures 1 to 6 illustrate the invention more particularly in the case where the shell bottom 9 or the base 1 comprises a hinge bearing 27 mounted around the axis of rotation A1, serving as a guide stop in any position of the support shell 3 between the open position and the various closed positions, when putting on and taking off the boot. The guide stop makes it possible to guide and pre-position the boot 2 of a user, in any position between the open position and the various closed positions. Thus, at the time of tightening, in the final phase of closing, horizontal sliding of the boot relative to the base is non-existent.

The two arms 19 which carry the pedal 5 are movable around the second axis of rotation A2 by two connections, which implement for example rivets 14. The pedal 5 controls the support shell 3 in the closed position in an automatic manner, without manual intervention. The arms 19 transmit a thrust from the user's boot 2 to the support shell 3, producing a driving torque from the initial opening position to one of the final closing positions, determined by the last notch 17 of the locking means 15 snapped with the elastic return lever 13, 13a, 13b.

In the illustrative examples provided by the Figures 1 and 2 , two connecting rods 29 are articulated to the arms 19 and articulated to the base 1 to increase the precision of the guidance of the pedal 5. This guidance system allows the arms 19 to perform a forward movement towards the front part of the base 1, then a backward movement towards the rear part, during the rotation of the support shell 3 around the axis of rotation A1. In other words, the connecting rod 21 makes it possible to absorb a horizontal component of the movement of the arms 19. The connecting rods 29 are articulated to the front part of the base 1 to produce in the open position, Figure 1 , loosening a front strap 31.

In the illustrative examples provided by the Figures 5 and 6 , the first arm 13a of the lever 13 is a hoop on which the second arm 13b is articulated. The hoop being articulated to the two hull sides 11, it cooperates advantageously with a single means 16 with notches 17 fixed to the support shell to distribute in a balanced manner the drive of the two hull sides 11 controlled by the lug 21. Thus, the risk is eliminated that the notches snapped onto one and the other hull side 11 are not homologous and lead to a slight twisting of the support shell 3.

Reference is made here to the request PCT/EP2019/069605 filed by the applicant and which is incorporated as regards the particular arrangement between the hull support and the base by means of a hinge bearing serving as a guide stop.

It should however be noted that the invention, in its generality, applies to any snowboard binding which, in accordance with the introductory disclosure, comprises a support shell movable relative to the base.

So, the Figure 7 illustrates a variant of the first embodiment, which differs from the example given by the Figure 2 in that the axis A1 of rotation of the support shell 3 relative to the base 1 passes through two pivot connections 28 arranged on each of the two hull sides 11. Unlike the previous illustrative examples, the two pivot connections 28 do not form a hinge bearing but only two point connections like rivets.
