Description

Snowboard binding with a support shell and multiple locking positions determined by a multi-notch locking mechanism. technical field

[0001] The invention relates to a snowboard binding comprising, more particularly, a base, a support shell movable relative to the base, and a pedal for controlling the support shell's rotation relative to the base between an open and a closed position. A means is provided for locking the support shell's rotation relative to the base in the closed position against the elastic return of a lever. The means comprises two notches for engaging with the lever. Previous technique

[0002] A snowboard binding of this type is known from document US2016175689A. According to this document, the means for locking the support shell to the baseplate includes a prong inserted into a recess in each of the two lateral arms of the pedal, to engage with the spring-return lever mounted around an axis of rotation relative to the baseplate. The two prongs form two engagement notches with two opposite ends of the lever, positioned relative to the axis of rotation and received in the recesses of the pedal's lateral arms. Another example of this type of snowboard binding is provided by document EP0824942, in which the two notches result from a recess formed in two lateral arms of the pedal, to engage with the spring-return lever, mounted around an axis of rotation relative to the baseplate.In another example, provided by document WOWO 2008 / 094974, the two notches result from a latch fixed on each side of the pedal to engage with the spring-return lever, fixed to the base.

[0003] In either of these documents, the elastic return lever is manually flipped to unlock the support shell from the closed position and allow the boot to be removed.

[0004] The state of the art reflected in these documents shows that it is limited to a single closing position for the snowboard binding. The resulting drawback is particularly noticeable when snow accumulates between the pedal and the baseplate. In this circumstance, which is very common in practice, it may prove impossible to rotate the support shell into the closed position and consequently to engage the spring-return lever with the locking mechanism. Description of the invention

[0005] One of the aims of the invention is therefore to modify the type of snowboard attachment described above, to guarantee that the support shell is locked in the closed position, under all circumstances.

[0006] To this end, the invention relates to a snowboard binding according to the introductory statement, characterized in that it includes a lug received in a fork of the notched means or lever to drive the locking means or lever into rotation, by unclipping the lever from one of the notches and clipping it with the other notch during the fitting.

[0007] Thus, the snowboard binding according to the invention allows the lever, by driving the fork by means of the lug, to click into different closing positions during the fitting, determined by the different notches of the locking means.

[0008] The lug can be fixed in the base, the support shell or the pedal.

[0009] According to the first embodiment, the notched means comprises a wheel having a notch forming the fork that receives the lug. The wheel may be rotatable relative to the support shell, and the lug may be fixed in the base. Alternatively, the wheel may be rotatable relative to the base, and the lug may be fixed in the support shell or in the pedal.

[0010] According to a second embodiment, the lever comprises a first movable arm rotating relative to the support shell and a second arm, articulated to the first arm and ratcheted with the notched means, which is fixed in the support shell, the first arm of the lever having a notch forming the fork, opposite the second arm and the lug being fixed in the base.

[0011] According to an alternative embodiment of the first mode, the lug is carried by a hull side of the support hull.

[0012] According to one embodiment of the second mode, the first arm of the lever is an articulated arch on two hull sides of the support hull.

[0013] These variants are particularly advantageous when a bottom of the support shell or the base includes 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 opening position and the closing positions, in putting on and taking off.

[0022] It should be noted that in the following exposition, the same element bears the same reference on one or the other of the figures. Way(s) of implementing the invention

[0023] A snowboard binding, illustrated in one of Figures 1 to 7, comprises a base 1, a support shell 3, a foot pedal 5, and a strap 7. The support shell 3 is movable around the axis of rotation A1 carried by the base 1. The foot pedal 5 and the strap 7 are designed to control the support shell 3 for entering and exiting the binding, respectively, between an open and a closed position. The support shell 3 comprises a base plate 9 and two side plates 11. The foot pedal 5 is articulated to the two side plates 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 a spring-return lever 13, 13a, 13b. This means 15, 16 includes two or more ratcheting notches 17.

[0024] The elastic return lever includes a 12-inch operating arm to be manually unclipped in order to unlock the support shell from the closed position and allow removal of the boot.

[0025] According to the invention, the snowboard binding includes a lug 21 received in a fork 20 of the notched means 15, 16 17 or of the lever 13, 13a, 13b to drive the notched means or the lever into rotation, by unclipping the lever from one of the notches 17 and clipping it with the other notch 17 during the fitting.

[0026] Figures 1 to 4 illustrate a first embodiment, in which the notched means 15 17 includes a cam or wheel provided with a notch 23 forming the fork 20 receiving the lug 21.

[0027] In the example of 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 which themselves carry the pedal 5 or carried, figure 2 or 3, by the shell sides 11, in this case along the axis A3 of articulation of the strap 7.

[0028] The elastic return lever 13 is movable relative to the base 1 around an axis of rotation A4 and is provided with a notch 25 to engage with the notches 17 of the wheel 15. The elastic return of the lever 13, obtained by a means known in itself and not shown in the figures, for example a spring, allows it to be in a butt against the wheel 15 while the latter is driven in rotation by the lug 21.

[0029] The drive 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 the fitting, the lever 13 to unclip from one notch 17 to clip with the next notch, so that the wheel 15 orders the succession of the different closing positions according to the succession of the notches.

[0030] In the example in Figure 4, the wheel 15 is free to rotate relative to the shell sides 11 and the lug 21 is fixed to the base 1. The spring-return lever 13 is also free to rotate relative to the shell sides 11. Note that, in this 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 in Figure 3.

[0031] 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 about an axis of rotation A4 and a second arm 13b, articulated to the first arm 13a about an axis of rotation A6 and ratcheted with the notched means 16 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 drive of the first arm 13a by the lug 21 allows the second arm 13b, while the support shell 3 is driven in rotation about the axis A1 by the pedal 5 during putting on the shoes, to disengage by one notch 17 to engage with the notch following, so that means 16 orders the succession of the different closing positions according to the succession of the notches.

[0032] It should be noted that each notch of the middle 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 locking triangle T, in any closed position of the support shell. Figure 5 illustrates a closed position determined by a first notch, while in Figure 6, the closed position is determined by a final notch.

[0033] Figures 1 to 6 illustrate the invention more particularly in the case where the boot base 9 or the footplate 1 includes 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, both when putting on and taking off the boot. The guide stop allows the user's boot 2 to be guided and pre-positioned in any position between the open position and the various closed positions. Thus, during tightening, in the final phase of closure, there is no horizontal slippage of the boot relative to the footplate.

[0034] The two arms 19 that support the pedal 5 are movable around the second axis of rotation A2 by means of two links, which employ, for example, rivets 14. The pedal 5 automatically controls the support shell 3 in the closed position, 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 open position to one of the final closed positions, determined by the last notch 17 of the locking means 15 engaged with the spring-return lever 13, 13a, 13b.

[0035] In the illustrative examples provided by Figures 1 and 2, two connecting rods 29 are articulated to the arms 19 and to the base 1 to increase the precision of the guidance of the pedal 5. This guidance system allows the arms 19 to move forward towards the front part of the base 1, and then backward towards the rear, during the rotation of the support shell 3 around the axis of rotation A1. In other words, the connecting rod 21 absorbs 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 loosen a front strap 31 in the open position, Figure 1.

[0036] In the illustrative examples provided by Figures 5 and 6, the first arm 13a of the lever 13 is a hoop on which the second arm 13b is articulated. Since the hoop is articulated to the two hull sides 11, it cooperates advantageously with a single notched means 16 17 fixed to the support shell to distribute the drive of the two hull sides 11, controlled by the lug 21, in a balanced manner. Thus, the risk is eliminated that the notches engaged on each hull side 11 might not be homologous and lead to a slight torsion of the support shell 3.

[0037] Reference is made here to PCT / EP2019 / 069605 filed by the applicant, which is incorporated as regards the particular arrangement between the support shell and the base by means of a hinge bearing serving as a guide stop.

[0038] It should be noted, however, that the invention, in its generality, applies to any snowboard attachment which, in accordance with the introductory statement, includes a support shell movable relative to the base.

[0039] Thus, Figure 7 illustrates a variant of the first embodiment, which differs from the example given by Figure 2 in that the axis A1 of rotation of the support shell 3 relative to the base 1 passes through two pivot joints 28 arranged on each of the two shell sides 11. Unlike the previous illustrative examples, the two pivot joints 28 do not form a hinge bearing but only two point joints such as rivets.
