Description

Technical Field

[0001] This invention relates to a ski binding, and more particularly includes a base, a support shell movable relative to the base, and a pedal for controlling the support shell when putting on shoes, the support shell rotating relative to the base between an open position and a closed position. A device is provided to prevent rotation of the support shell relative to the base in the closed position by resisting the elastic return of a lever. The device includes two slots that lock with the lever. Background Technology

[0002] This type of ski binding is known from the document patcit0001: US 2016175689 A.

[0003] According to this document, the device for supporting the base stop includes a leading edge that receives in a slot in each of the two side walls of the pedal to lock with a resilient return lever mounted about a rotation axis relative to the base. The two leading edges form two notches that lock with the two ends of the lever, the ends being opposite to the rotation axis and received in the slots in the side walls of the pedal. Document patcit0002: EP 0824942 provides another example of this type of ski binding. In this example, the two notches originate from recesses formed on the two side arms of the pedal to lock with a resilient return lever mounted about a rotation axis relative to the base. In another example provided in document patcit0003: WO 2008 / 094974, the two notches originate from latches fixed to each side of the pedal to lock with a resilient return lever fixed to the base.

[0004] In any of these documents, the resilient reset lever is manually reversed to unlock the support shell from the closed position and allow for shoe removal.

[0005] The existing technology reflected in these documents indicates that it is limited to a single closed position of the ski binding. The resulting drawbacks are more pronounced when there is snow accumulation between the pedal and the base. In this situation, which is very common in practice, it has proven impossible to pivot the support shell to the closed position, thereby locking the resilient return lever with the locking mechanism. Summary of the Invention

[0006] Therefore, one of the objectives of this invention is to modify the above-described type of ski binding to ensure that the support shell can be locked in the closed position under any circumstances.

[0007] Therefore, the present invention relates to a ski binding conforming to the description, characterized in that it includes a pin that is received in a fork-shaped part of a slotted device or lever, so as to drive the stop or lever to rotate during the wearing of the skis by disengaging the lever from one slot and locking the lever with the other slot.

[0008] Thus, the ski binding according to the invention allows the lever, driven by the fork-shaped member by the convex pin, to lock in different closing positions during the wearing process according to the different slots of the locking device.

[0009] The protruding pin can be fixed in the base, support shell, or pedal.

[0010] According to a first embodiment, the slotted device includes a wheel with a recess forming a fork-shaped part to receive a protrusion. The wheel is rotatable relative to the support housing and the protrusion and is fixed to the base. Alternatively, the wheel is movable relative to the base and the protrusion and is fixed in the support housing or a pedal.

[0011] According to the second embodiment, the lever includes a first arm that is rotatably movable relative to the support shell and a second arm that is hinged to the first arm and locked with a slotted device. The second arm is fixed in the support shell. The first arm of the lever is provided with a notch forming a fork-shaped part, the notch being opposite to the second arm, and a protrusion fixed in the base.

[0012] According to a variation of the first embodiment, the protruding pin is supported by the side shell of the supporting shell.

[0013] According to a variation of the second embodiment, the first arm of the lever is an arched member hinged to the two side shells of the support shell.

[0014] These variations are more advantageous when the base or base of the support plate includes a hinge bearing mounted about the axis of rotation of the support shell relative to the base, and the hinge bearing serves as a guide stop for the support shell in various positions between the open and closed positions when putting on and taking off shoes.

[0023] It should be noted that in the following description, the same elements in different figures use the same reference numerals. Detailed Implementation

[0024] Figures 1 to 7 One of the ski bindings shown includes a base 1, a support shell 3, a pedal 5, and a strap 7. The support shell 3 is movable about a rotation axis A1 carried by the base 1. The pedal 5 and the strap 7 are configured to control the support shell 3 between an open position and a closed position when putting on and taking off shoes, respectively. The support shell 3 includes a bottom shell 9 and two side shells 11. The pedal 5 is hinged to the two side shells 11 about a rotation axis A2. The strap 7 is hinged to the support shell 3 about a rotation axis A3. Devices 15 and 16 are configured to resist resilient return levers 13, 13a, and 13b, stopping the support shell 3 from rotating relative to the base 1 in the closed position. Such devices 15 and 16 include two or more locking slots 17.

[0025] The resilient reset lever includes an operating arm 12 for manual unlocking to release the support shell from the closed position and allow for shoe removal.

[0026] According to the invention, the ski binding includes a pin 21 that is received in a fork 20 of a device 15, 16 or lever 13, 13a, 13b having slots 17 for unlocking from one of the slots 17 by levers when putting on the skis and for driving the slotted device or driving the lever to rotate by locking with the other slot 17.

[0027] Figures 1 to 4 The first embodiment is shown, wherein the device 15 having a slot 17 includes a cam or a wheel having a notch 23 forming a fork-shaped part that receives a protrusion 21.

[0028] exist Figure 1 , 2 In the example shown in Or 3, wheel 15 is supported by base 1 about rotation axis A5, and is controlled by protrusion 21, which is in Figure 1 The middle is supported by the two side walls 19 of the supporting pedal 5, or Figure 2 or Figure 3 In this case, the middle is supported by the side shell 11 along the hinge axis A3 of the pull strap 7.

[0029] The resilient return lever 13 is movable relative to the base 1 about the axis of rotation A4 and has a slot 25 for locking with the slot 17 of the wheel 15. The resilient return lever 13, obtained by means of a known device not shown in the figure, such as a spring, allows the wheel 15 to stop against the wheel 15 during rotation driven by the pin 21.

[0030] When the support shell 3 is driven by the pedal 5 to rotate around the axis A1 during the shoe-wearing process, the wheel 15 is driven by the convex pin, allowing the lever 13 to disengage from the slot 17 to lock with the next slot. In this way, the wheel 15 provides a series of different closing positions according to the successive slots.

[0031] exist Figure 4 In the example shown, wheel 15 is rotatable relative to side shell 11, while pin 21 is fixed to base 1. Resilient return lever 13 is also rotatable relative to side shell 11. It should be noted that in this embodiment, the side arm 19 of pedal 5 is only hinged to support shell 3, while... Figure 3 In the example, the side arm is also hinged to the base 1.

[0032] Figure 5 and Figure 6 A second embodiment is shown, wherein the lever 13 includes a first arm 13a movable relative to the support shell 3 about a rotation axis A4, and a second arm 13b hinged to the first arm 13a about a rotation axis A6 and locked to a device 16 with a slot 17 fixed to the base. The first arm 13a is provided with a notch 23 forming a fork-like shape, opposite to the second arm 13b, while a pin 21 is fixed in the base 1. The first arm 13a is driven by the pin 21, which allows the second arm 13b to disengage from one slot 17 to lock with the next slot as the support shell 3 is rotated about axis A1 by the pedal 5 during shoe-wearing, so that the device 16 provides successive different closed positions according to the successive slots.

[0033] It should be noted that in each closed position of the support housing, each slot of the device 16, with the hinge of the first arm to the support housing and the hinge of the second arm to the first arm, forms a locking triangle T. Figure 5 The first closed position, defined by the first slot, is shown, while Figure 6 The closing position is shown, as determined by the last slot.

[0034] Figures 1 to 6 More specifically, the invention is illustrated in which the bottom shell 9 or base 1 includes a hinge bearing 27 mounted about a rotation axis A1, which acts as a guide stop for the support shell 3 at each position between the open position and different closed positions during putting on and taking off the shoes. The guide stop allows the user's boot 2 to be guided and pre-positioned in each position between the open position and different closed positions. Therefore, when tightened, there is no horizontal sliding of the boot relative to the base during the final stage of closure.

[0035] The two arms 19 supporting the pedal 5 are movable around a second axis of rotation A2 via two connectors, such as rivets 14. The pedal 5 automatically controls the support housing 3 to the closed position without manual intervention. The arms 19 transmit thrust from the user's boot 2 to the support housing 3, while generating a driving torque from the initial open position to one of the final closed positions, one of which is determined by the last slot 17 of the locking device 15 that locks with the resilient return levers 13, 13a, 13b.

[0036] exist Figure 1 and Figure 2 In the provided example, two links 29 are hinged to arm 19 and to base 1 to improve the guiding accuracy of pedal 5. This guiding system allows arm 19 to move forward toward the front of base 1 and then retract backward as support housing 3 rotates about axis A1. In other words, link 29 allows the horizontal portion of the movement of arm 19 to be absorbed. Link 29 is hinged to the front of base 1 so that in the open position… Figure 1 This results in the release of the front pull belt 31.

[0037] exist Figure 5 and Figure 6 In the illustrative example provided, the first arm 13a of lever 13 is an arched member, and the second arm 13b is hinged to the arched member. The arched member is hinged to the two side shells 11, and the arched member advantageously engages with a single device 16 with a slot 17 fixed to the support shell for evenly distributing the drive of the two side shells 11 controlled by the pin 21. In this way, there is no risk of inconsistent slots locking onto one of the side shells 11, which could lead to slight torsion of the support shell 3.

[0038] Reference is made here to the applicant’s application PCT / EP2019 / 069605, which contains a special arrangement between the support housing and the base via a hinge bearing that acts as a guide stop.

[0039] However, it should be noted that the present invention is generally applicable to all types of ski bindings, and according to the introductory description, the present invention includes a support shell that is movable relative to the base.

[0040] so, Figure 7 A variation of the first embodiment is shown, which is similar to... Figure 2 The difference in the example given is that two pivoting connectors 28 arranged on each of the two side shells 11 are connected by the axis of rotation A1 of the support shell 3 relative to the base 1. Unlike the example shown earlier, the two pivoting connectors 28 do not form hinge bearings, but are only two point connectors, such as rivets.
