Description

Technical Field

[0001] The present invention relates to the technical field of outdoor ski equipment, and in particular to a clamping assembly for a ski binding and the ski binding. Background Art

[0002] Snowboarding, like skiing, is a popular winter sport. To secure boots and snowboards, bindings are required. Bindings are generally categorized into soft bindings, step-in bindings, and strap-in bindings. Step-in bindings are the most commonly used.

[0003] Chinese patent document CN107106903B discloses a ski binding and a boot. The binding is provided with a slot on the toe to prevent the boot from sliding upward. The toe of the boot is stepped down to enter the slot to form a locking position. During actual sliding, the boot needs to be stepped down to deform the slot so that the positioning member enters the annular slot to achieve fixation. Due to the way it is inserted and removed, there is a certain amount of space between the positioning member of the boot and the slot. During sliding, the boot and the binding are prone to shaking and bumping in the up and down directions, resulting in a "clicking" sound. In addition, the interference fit structure requires the boot to apply a large force to step into the slot. During the actual wearing and taking off process, especially in slope snow or powder snow environments, it is time-consuming and laborious to insert and remove the boot from the binding, affecting the skiing experience. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the prior art in that abnormal noise is easily generated between the binding and the toe of the boot when skiing and the binding is difficult to put on and take off, thereby providing a snap-on assembly for a ski binding and a ski binding.

[0005] In order to solve the above problems, the present invention provides a clamping assembly, comprising:

[0006] a first positioning member, provided at the toe portion of the boot;

[0007] A toe fixing member is pivotally mounted on the bottom plate of the fixing device, wherein the toe fixing member is provided with a clamping portion that is driven to rotate synchronously;

[0008] The first positioning member is driven by an external device to move toward the toe fixing member and then engages with the engaging portion. The engaging portion is driven to pivot, so as to form a tight contact state between the engaging portion and the first positioning member.

[0009] Furthermore, the toe fixing member also includes: a supporting body, which is coaxially connected to the clamping part, and the supporting body drives the clamping part to pivot under the pressure of the boot to form a tight state between the clamping part and the first positioning member.

[0010] Furthermore, an abutment portion is configured on a side of the free end of the support body facing away from the bottom plate. The abutment portion protrudes from the support body and is used to abut against the pressing end surface of the boot.

[0011] Furthermore, the abutting portion is a first protrusion protruding from the supporting body, and a second protrusion is provided on the abutting end surface of the bottom plate corresponding to the boot.

[0012] Furthermore, a biasing member is provided on the toe fixing member, and the biasing member applies a biasing force to the clamping portion to cause it to pivot toward the bottom plate.

[0013] Furthermore, the clamping portion includes: a first restraint member for preventing the first positioning member from moving away from the heel direction, and a second restraint member for resisting the first positioning member from moving away from the base plate direction, and the second restraint member is bent toward the heel direction relative to the first restraint member.

[0014] Furthermore, the slot is a U-shaped slot formed by the first restraining member and the second restraining member. When the boot presses against the supporting body, the first positioning member and the second restraining member are pressed tightly.

[0015] Furthermore, the support body extends outwardly toward the toe portion to form a support plate, and the support plate is suitable for supporting the boot in a pressed state.

[0016] In addition, the present invention also provides a ski binding, comprising the clamping assembly as described in any one of the above items.

[0017] Furthermore, it also includes:

[0018] a second positioning member, provided at the heel of the boot;

[0019] a heel restraint member fixedly mounted on the holder, the heel restraint member having a guide channel for accommodating the second positioning member;

[0020] a clamping member rotatably disposed on the heel restraining member, the clamping member having a first protruding end and a second protruding end coaxially connected, the first protruding end extending into the interior of the guide channel;

[0021] In the boot locked state, the second protruding end abuts against the outer side wall of the heel restraint member so that the first protruding end blocks the guiding channel; in the boot unlocked state, the first protruding end is pushed by the second positioning member extending into the guiding channel to drive the second protruding end to pivot, so as to release the blocking of the guiding channel.

[0022] The technical solution of the present invention has the following advantages:

[0023] 1. The clamping component provided by the present invention is provided with a first positioning member at the toe of the boot and a toe fixing member on the bottom plate of the binding. The toe fixing member is provided with a clamping portion that rotates synchronously under drive. Since the first positioning member moves towards the toe fixing member under external drive and is clamped in the clamping portion, the clamping portion pivots under drive to form a tightened state between the clamping portion and the first positioning member. During this process, due to the pivoting action of the clamping portion at a certain angle, it gradually clamps the first positioning member as it pivots, reducing the play, so that the toe of the boot and the binding have a better fixing effect, avoiding the up-and-down knocking and shaking of the first positioning member and the clamping portion after fixation, and thus avoiding abnormal noises.

[0024] In addition, since the first positioning member only needs to be displaced towards the toe fixing member to be clamped in the clamping portion, during the actual wearing and taking off process, especially in the powder snow or slope snow environment, it is more labor-saving than the way of constraining the binding after deforming it by stepping on it up and down, and the operation is simple and convenient, which is beneficial to improving the skiing experience.

[0025] 2. The clamping component provided by the present invention, the toe fixing member further includes a supporting body. Since the supporting body and the clamping portion are coaxially connected, the supporting body will drive the clamping portion to pivot under the pressing action of the boot. When the boot steps on the bottom plate of the binding, the supporting body is stepped on by the boot and is in a horizontal position, which is beneficial to ensuring that the first positioning member and the clamping portion are in a tightened state and further ensuring the fixing effect between the clamping portion and the first positioning member.

[0026] 3. The clamping component provided by the present invention is provided with a first protrusion protruding from the free end of the supporting body, and a second protrusion is provided on the pressing end surface of the bottom plate corresponding to the boot. This setting is beneficial to further improving the clamping and fixing effect between the first positioning member and the clamping portion after the boot steps on the supporting body.

[0027] 4. The clamping component provided by the present invention, the clamping portion includes a first restraint member and a second restraint member bent relative to the first restraint member. The first restraint member and the second restraint member jointly form a U-shaped groove. Through this setting, the first positioning member is clamped in the U-shaped groove and abuts against the first restraint member and the second restraint member respectively, which is beneficial to ensuring a good fixing effect between the first positioning member and the clamping portion and preventing knocking and abnormal noises.

[0028] 5. The clamping assembly provided by the present invention has a support plate extending outward toward the toe portion on the support body, and the support plate is suitable for supporting the boots in a pressed state. Here, the support plate can further enhance the supporting effect on the boots and prevent the toe portion of the boots from excessively tilting forward and affecting the fixing state of the fastener.

[0029] 6. The ski binding provided by the present invention comprises the snap-on assembly as described in any one of the above items, and thus has all the advantages of the snap-on assembly.

[0030] Furthermore, since the first extension end blocks the guide channel when the boot is locked, and the second extension end abuts against the outer wall of the restraining member, it is avoided that when the second extension end is disposed inside the restraining member, an external adjustment member is required to adjust the state, thereby preventing the continuous closed state of the guide channel from being affected. Therefore, when the boot is locked, snow is effectively prevented from entering the guide channel blocked by the first extension end and the second extension end. When the second extension end is operated, snow that enters through the gap can be discharged from the channel, thereby preventing the snow from freezing and affecting the adjustable flexibility of the clamping member.

[0031] Furthermore, the first extension of the present invention is located within the guide channel, while the second extension is pivotally positioned on the outer wall of the restraining member, thereby forming a lever-connected state between the first and second extensions. When the first extension is pushed upward by the positioning block, the second extension is restrained by the outer wall of the restraining member, preventing it from rotating further. This effectively enhances the restraining effect of the clamping member on the positioning block, strengthens the overall structural strength after locking, and prevents the boot from accidentally falling upward. Furthermore, the binding of the present invention has a simple structure, requires few assembly components, is easy to manufacture and maintain, and reduces the probability of problems, thus providing excellent performance.

[0050] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0051] Example 1

[0052] The present embodiment relates to a snap-fit ​​assembly, which is applied to a ski binding, including a first positioning member 11 provided on the toe of the boot 1, and a toe fixing member provided on the base plate 21 of the binding 2. The toe fixing member is pivotally arranged relative to the base plate 21, and a snap-fit ​​portion 32 driven to rotate synchronously is provided on the toe fixing member. The first positioning member 11 is externally driven to move toward the toe fixing member and is snap-fitted into the snap-fit ​​portion 32. The snap-fit ​​portion 32 is driven to pivot to form a tight state between the toe fixing member and the first positioning member 11.

[0053] Based on the above overall structural design, an implementation method of the clamping assembly described in this embodiment is as follows Figure 2 As shown, the base plate 21 of the fixing device 2 is fixedly mounted on a snowboard (the snowboard is not shown in the figure), and a first positioning member 11 is provided on both sides of the toe of the boot 1, and two clamping parts 32 are provided corresponding to the first positioning members 11. For the convenience of description, the following description in this embodiment is based on the structural form of providing two first positioning members 11, which will not be repeated in the following.

[0054] like Figure 1 As shown, in this embodiment, the first positioning member 11 adopts the existing mature high-strength metal or impact-resistant deformation plastic support, which is preferably a blocking block fixed on the side of the boot 1. In order to reduce the friction between the first positioning member 11 and the clamping part 32, the circumferential chamfer of the blocking block is set.

[0055] like Figure 3As shown, the engaging portion 32 in this embodiment includes a first restraining member 321 for preventing the first positioning member 11 from moving away from the heel, and a second restraining member 322 for resisting movement of the first positioning member 11 away from the base plate 21. The second restraining member 322 is bent toward the heel relative to the first restraining member 321. As an alternative embodiment, the engaging portion 32 is a U-shaped engaging slot 33 opened toward the rear end of the retainer 2, and is configured to engage and plug into the first positioning member 11.

[0056] Here, the bottom surface of the second restraining member 322, which abuts the first positioning member 11, is tilted downward at an acute angle along the horizontal direction. This arrangement further enhances the tight fit between the boot 1 and the binding 2 and helps reduce the distance between the first positioning member 11 and the second restraining member 322. Here, the free end of the second restraining member 322 extends to the end surface of the U-shaped slot 33 in a smooth transition, further facilitating the insertion of the toe of the boot 1 into the U-shaped slot 33 and improving the smooth fit between the boot 1 and the engaging portion 32.

[0057] In this embodiment, the toe fastener further comprises a support body 31 coaxially connected to the clamping portion 32. The support body 31, under the pressure of the boot 1, drives the clamping portion 32 to pivot, thereby creating a tight abutment between the clamping portion 32 and the first positioning member 11. The support body 31 and the first restraining member 321 of the clamping portion 32 are integrally formed, and a through-hole is defined at the junction of the two. The support body 31 and the clamping portion 32, via a pivot axis extending through the through-hole, creates a pivoting effect for the toe fastener on the fastener 2.

[0058] Here, the plane where the support body 31 is located extends toward the horizontal plane. To avoid interference between the support body 31 and the clamping portion 32, the clamping portion 32 is positioned corresponding to the position where the first positioning member 11 of the boot 1 is located, that is, the clamping portion 32 is disposed on both sides of the support body 31. When the boot 1 steps on the base plate 21 of the binding 2, the bottom surface of the boot 1, where the toe is located, presses against the upper surface of the support body 31. The support body 31 pivots in direction A under the pressure, thereby driving the clamping portion 32 to pivot in the same direction. Since the first positioning member 11 extends into the clamping portion 32 during the downward stepping process of the boot 1, the clamping portion 32, driven by the support body 31 to pivot, tends to press in direction A, causing the lower surface of the clamping portion 32 to press against the upper surface of the first positioning member 11, thereby reducing the shaking of the toe of the boot 1 and the resulting abnormal noise.

[0059] like Figure 3 and Figure 4As shown, as an alternative embodiment, the free end of the support body 31 in this embodiment is configured with an abutment portion on the side facing away from the base plate 21. The abutment portion protrudes from the support body 31 and is configured to abut the pressing end surface of the boot 1. Here, the abutment portion is a first protrusion 34 protruding from the support body 31. When the bottom surface of the boot 1 abuts the upper surface of the support body 31, it first abuts the first protrusion 34, driving the support body 31 to pivot in the direction A. This helps to ensure that the support body 31 is always clamped between the boot 1 and the base plate 21 of the binding 2, thereby facilitating the clamping portion 32 to abut against the first positioning member 11.

[0060] As a further alternative embodiment, a second protrusion 35 is provided on the pressing end surface of the base plate 21 corresponding to the boot 1. The second protrusion 35 is formed on the base plate 21 near the toe position. When the boot 1 presses against the base plate 21 and the support body 31, the bottom surface of the toe of the boot 1 is supported by the second protrusion 35, which is conducive to the first positioning piece 11 of the toe pressing upward against the clamping part 32.

[0061] It should be noted that, assuming the first and second protrusions 34, 35 are made of the same material, the height of the second protrusion 35 is preferably greater than that of the first protrusion 34 to further enhance the abutment between the first positioning member 11 and the engaging portion 32. The first and second protrusions 34, 35 can be made of an elastic material such as sponge. When the boot 1 steps on the binding 2, the sole of the boot 1 first contacts the first and second protrusions 34, 35. After contact, the toe portion of the boot 1 is restrained by the toe binding 2, limiting its upward movement. This abutment further clamps the toe portion of the boot 1, preventing the toe binding 2 from loosely securing the toe portion of the boot 1 and causing unusual noise and shaking during skiing. When the material of the first protrusion 34 has a greater degree of elastic deformation than the material of the second protrusion 35, the heights of the first and second protrusions 34, 35 can be the same, as long as they maintain a firm abutment against the boot 1.

[0062] In this embodiment, as an alternative, the support body 31 may be omitted, and a biasing member may be provided on the toe fastener to bias the engaging portion 32 toward direction A. In a specific embodiment, the biasing member is a conventional torsion spring, one end of which is fixed to the engaging portion 32, and the other end of which is fixed to the base plate 21 of the fastener 2. The torsion spring exerts an elastic force that causes the engaging portion 32 to pivot toward direction A. With this arrangement, when the first positioning member 11 of the boot 1 is inserted into the engaging portion 32, the engaging portion 32 is subjected to the dual forces of the biasing member and the footsteps of the boot 1, resulting in a more secure contact between the boot 1 and the engaging portion 32, thereby preventing the first positioning member 11 from dislodging from the engaging portion 32. As another alternative, the biasing member may be an electromagnet.

[0063] In addition, Figure 5 As shown, in this embodiment, a support plate 323 is formed on the support body 31 extending outward toward the toe. The support plate 323 is arranged on the base plate 21 corresponding to the toe sole position of the boot 1. When the boot 1 steps on the base plate 21 of the fixing 2, the toe part of the boot 1 is supported by the support plate 323, which can further enhance the stability between the fixing 2 and the boot 1, thereby improving the skiing experience.

[0064] As an alternative embodiment, a support pad suitable for supporting the boot 1 is provided on the base plate 21 of the holder 2. The support pad can be made of an existing mature wear-resistant and non-slip pad material, or a sponge pad with a certain degree of elasticity. The provision of the support pad can, on the one hand, further reduce the relative displacement between the boot 1 and the base plate 21 of the holder 2 and can act as a buffer. On the other hand, when the boot 1 is stepped on, the toe clip is supported by the support pad and can be pressed against the matching slot 33, thereby further reducing the shaking and abnormal noise of the toe and the matching slot 33. Here, the plane where the support pad is located after the maximum deformation should be lower than the aforementioned first protrusion 34 and second protrusion 35 to ensure the first protrusion 34 and second protrusion 35 have a pressing effect on the boot 1.

[0065] It should be noted that the clamping assembly mentioned in this embodiment is mainly used to restrain and fix the toe part of the boot 1 after it steps on the fastener 2. The heel part of the boot 1 can adopt the existing mature fastener 2 structure, or be fixed by setting a strap on the fastener 2. It is only necessary to ensure that the toe of the boot 1 is first clamped in the clamping part 32, and then the heel is fixed to prevent the heel of the boot 1 from moving upward and forward.

[0066] How it works:

[0067] As shown in the figure, the toe portion of the boot 1 is first inserted in the direction corresponding to the clamping portion 32. During this process, the first positioning member 11 of the boot 1 is correspondingly clamped in the U-shaped groove formed by the first restraining member 321 and the second restraining member 322. Then, the whole boot 1 is stepped downwards to abut against the bottom plate 21 of the retainer 2. Since the boot 1 presses against the bottom plate 21 of the retainer 2, the support body 31 is pivoted towards the A direction, and the support body 31 drives the clamping portion 32 to pivot in the same direction. When the boot 1 completely steps on the bottom plate 21, the support body 31 is in a horizontal position, and the second restraining member 322 on the clamping portion 32 abuts tightly against the first positioning member 11 of the boot 1 to form a fixation; when it is necessary to release the clamping state, first release the fixation of the heel portion of the boot 1, lift the heel portion of the boot 1 upwards, and finally pull out the toe portion of the boot 1.

[0068] Of course, the specific manner in which the clamping portion 32 is driven to pivot is not specifically limited in this embodiment. In other embodiments, the pressing force of the boot 1 can also be replaced by an electric control or manual rotation method, so that the clamping portion 32 is driven to pivot, so as to form the abutting state between the clamping portion 32 and the first positioning member 11.

[0069] Embodiment 2

[0070] This embodiment relates to a ski binding, including the clamping component as described in Embodiment 1.

[0071] As a further implementation manner, the ski binding in this embodiment further includes a second positioning member 12 provided at the heel portion of the boot 1, and a heel restraining member 22 fixed to the retainer 2. The heel restraining member 22 has a guiding channel 24 for the second positioning member 12 to extend into. A clamping member is rotatably provided on the heel restraining member 22. The clamping member has a first extending end 41 and a second extending end 42 coaxially fixed. The first extending end 41 extends into the interior of the guiding channel 24.

[0072] In the locked state of the boot, the second extending end 42 abuts against the outer wall of the heel restraining member 22, so that the first extending end 41 blocks the guiding channel 24; in the unlocked state of the boot, the first extending end 41 is pushed by the action of the second positioning member 12 extending into the guiding channel 24 to drive the second extending end 42 to pivot, so as to limit the position of the second positioning member 12. <0000​​As shown, the guide channel 24 on the heel restraint member 22 extends downward in the height direction. Preferably, the guide channel 24 is arranged in a slot shape, and a through opening is provided on the side facing the toe portion to facilitate the second positioning member 12 of the boot 1 to extend downward into the guide channel 24. Here, a pivot shaft is provided on the outside of the guide channel 24, that is, on the side of the heel restraint member 22 away from the heel portion of the boot 1. The clamping member is mounted on the pivot shaft and has an opening at the end thereof corresponding to the end extending from the outer wall of the heel restraint member 22 to facilitate the extension of the second extending end 42.

[0074] In this embodiment, the shape of the second positioning member 12 is adapted to the guide channel 24. The side baffles 241 of the slot-shaped guide channel 24 relatively restrict the positioning member from moving forward. Therefore, the guide channel 24 also resists the forward movement of the boot 1. This configuration avoids the need for additional straps to secure the boot 1, thereby reducing the time required to put on and take off the boot 1 and the binding 2. It should be noted that the baffles 241 do not need to be provided on the guide channel 24; they only need to guide the second positioning member 12 into the guide channel 24.

[0075] Here, the clamping member in this embodiment also includes a biasing member provided on the heel restraint member 22, and the biasing member is used to bias the second protruding end 42 to abut against the outer wall of the heel restraint member 22. As one specific embodiment, the biasing member is an elastic member connected to the clamping member and the retainer 2, respectively. The elastic member can be an existing mature torsion spring component, one end of which is attached to the bottom surface of the first protruding end 41 and the other end is attached to the side of the heel restraint member 22. The force of the torsion spring is the aforementioned biasing force. Here, the provision of the biasing member can further ensure that the second protruding end 42 abuts against the outer wall of the heel restraint member 22 in a natural state, so as to ensure the stable clamping effect of the clamping member and prevent the second protruding end 42 from accidentally pivoting during skiing to affect the locking state of the boot 1.

[0076] It should be noted that when the first extension end 41 is pivoted by the second extension end 42, its final pivoted position should be sufficient to allow the second positioning member 12 to escape from the guide channel 24. As one embodiment, a recessed groove is formed on the side wall of the guide channel 24, and the first extension end 41 enters the recessed groove after pivoting, thereby preventing interference between the first extension end 41 and the second positioning member 12. As another alternative embodiment, the side wall of the guide channel 24 can be hollowed out. In the hollowed-out state, pivoting the second extension end 42 can drive the first extension end 41 to move, and the rotation of the second extension end 42 can push out snow accumulated in the hollowed-out position, thereby further reducing the amount of snow that enters the fixture 2 and facilitating a good fixation state.

[0077] like Figure 7 and Figure 8 As shown, the aforementioned locked boot state refers to a state in which the second positioning member 12 enters the guide channel 24 and is blocked by the first protruding end 41 in its natural state and cannot escape from the guide channel 24; the unlocked boot state refers to a state in which the locking member is pivoted by an external force and releases the blockage of the guide channel 24. It should be noted that, preferably, the second positioning member 12 is shaped to match the guide channel 24 to further enhance the coordination between the second positioning member 12 and the guide channel 24.

[0078] In addition, the first protruding end 41 is preferably a plate type formed corresponding to the guide channel 24. When the side wall of the heel restraint member 22 is in a hollow state, the second protruding end 42 is preferably a plate type formed corresponding to the heel restraint member 22. Due to the above arrangement, in the locked state, the first protruding end 41 blocks the upper opening of the guide channel 24. When in the skiing state, the first protruding end 41 always blocks the guide channel 24, and the second protruding end 42 always blocks the hollow part of the heel restraint member 22, thereby preventing snow from entering the guide channel 24 and preventing snow from forming ice and affecting the normal pivoting action.

[0079] As an alternative embodiment, the heel restraint member 22 in this embodiment is provided with a clamping plate 43 which rotates coaxially with the clamping member, and the clamping plate 43 is located between the second protruding end 42 and the outer side wall of the heel restraint member 22. The clamping plate 43 is suitable for driving the second protruding end 42 to pivot in conjunction so that the first protruding end 41 can be disengaged from the blockage of the guide channel 24.

[0080] The specific structure is as follows Figure 8 As shown, the card plate 43 is an extension member coaxially fixed to the card connector, and its free end is bent relative to the main body of the card plate 43 to form a bent portion, and the shape of the bent portion is adapted to the shape of the bottom end of the outer wall of the heel restraint member 22. In a natural state, the biasing member acts on the second protruding end 42 to have a pivoting tendency in the opposite direction of B, and the second protruding end 42 presses the card plate 43 so that the bent portion of the pressure plate abuts against the outer wall of the heel restraint member 22. In addition, the bent portion can be used as a handle, which is more conducive to external operation of the card plate 43, thereby facilitating the application of force.

[0081] By setting the card plate 43, when the boot 1 tends to fall out of the guide channel 24 during skiing, the second positioning member 12 pushes the end of the first protruding end 41 to pivot it in the opposite direction B. In this process, the lever principle is used to make the bent part of the card plate 43 press against the outer wall of the heel restraint member 22, thereby extending the force arm of the second protruding end 42, which is beneficial to reducing the external force on the second protruding end 42 when the boot is unlocked, and the operation is simple and labor-saving; in addition, the card plate 43 can extend downward and attach to the outer wall of the heel restraint member 22, which is beneficial to the second protruding end 42 having a stable pressure-bearing capacity.

[0082] How it works:

[0083] The toe of the boot 1 is relatively tilted downward, and the clip of the boot 1 is aligned with the matching slot 33 and moved toward the toe fixing member and then locked in. Then the heel of the boot 1 is aligned with the guide channel 24 and stepped down. During this process, the convex guide surface of the second positioning member 12 pushes the first protruding end 41 to pivot in the direction B shown in the figure. When the second positioning member 12 passes over the first protruding end 41, the second protruding end 42 is biased by the biasing member to drive the first protruding end to pivot in the opposite direction of direction B. Since the card plate 43 is attached to the outer wall of the heel restraint member 22, when the second protruding end 42 is biased by the biasing member and abuts against the card plate 43, the second protruding end stops pivoting, and the first protruding end 41 re-blocks the guide channel 24. When the boot 1 needs to be removed, the external force pivots the card plate 43 in the direction B, and the second protruding end 42 drives the first protruding end 41 to make way for the disengagement space of the second positioning member 12. The heel of the boot 1 first disengages from the guide channel 24, and then the boot 1 is displaced in the opposite direction of the toe relative to the fastener 2 to disengage the first positioning member from the mating slot 33.
