Description

Technical Field

[0001] This utility model relates to the field of ski equipment technology, specifically to a binding and skis. Background Technology

[0002] In recent years, with the popularization of skiing, the technology of ski equipment has also been continuously improving. As a key component connecting skis and ski boots, bindings directly affect the skier's experience and safety. Traditional strap-on bindings, while simple in structure, are cumbersome to put on and take off, requiring manual tightening of multiple straps, which is time-consuming and physically demanding, especially on short slopes or indoor ski resorts where frequent putting and taking off is inconvenient. To improve this, some quick-put bindings have emerged on the market. Some of these use a specially designed ski boot and buckle structure for quick putting on and taking off, but they are not compatible with ordinary ski boots, increasing the cost of use. Other bindings are not limited to any particular ski boot, have complex structures, are expensive, and their tightening effect at the toes and ankles is not ideal, making them prone to loosening.

[0003] Therefore, there is an urgent need for a binding solution that is simple in structure, highly compatible, quick to put on and take off, and low in cost to meet skiers' needs for efficiency, convenience, and safety. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the problems of complex structure and poor compatibility of the binding in the prior art, thereby providing a binding and ski.

[0005] To solve the above-mentioned technical problems, this utility model provides a binding device, including: a base, a back plate, a first strap, and a second strap. The base is used to install on a ski, and two spaced-apart vertical plates are provided on the base, the vertical plates being used to support the sides of the ski boot. The back plate is rotatably disposed at the rear of the vertical plates via a first pivot. The back plate has a support portion and side plates. The side plates extend forward from both sides of the support portion, and the base of the support portion extends backward. The first pivot is disposed in the middle region of the side plates, and a footboard is rotatably disposed at the front end of the side plates. The first strap is provided with... The first strap is used to secure the ankle of the snowshoe, which is placed on the base or the side plate. The second strap is located at the front of the base and is used to secure the toe of the snowshoe. In the open state, the back plate flips backward, causing the pedal to flip upward, so that a space is formed between the back plate and the first strap for the snowshoe to enter. In the locked state, when the snowshoe is stepped on, it moves towards the base, causing the back plate to rotate. The back plate presses against the back of the lower leg and / or ankle of the snowshoe and pushes the snowshoe toward the front of the base so that the toe of the snowshoe is pressed against the second strap.

[0006] In use, when the device is in the open position, flipping the back panel backward causes the side panels to flip the pedals upward, extending the base of the support relative to the side panels. This increases the space between the back panel and the first strap, allowing the skis to easily enter and step onto the pedals. In the locked position, as the skis are stepped towards the base, the pedals, through the side panels, cause the support to flip forward. The support, while pressing against the back of the skis' calves and / or ankles, pushes the skis towards the front of the base, where they press against the second strap. Simultaneously, the first strap locks the skis at the ankle. This binding has a simple structure and is compatible with various skis. The binding provided by this invention solves the problems of complex structures and poor compatibility in existing binding technologies.

[0007] Optionally, the support portion is rotatably mounted on the side plate, and a concave first ankle cup is provided at one end of the side plate near the support portion; the back plate is in an unfolded state, with the base of the support portion abutting against the upper part of the first ankle cup; the back plate is in a folded state, with the support portion flipped towards the front end. Through the above configuration, the concave first ankle cup connects the two side plates into one unit, enhancing the strength of the side plates. In the unfolded state of the back plate, the support portion flips away from the base so that the base of the support portion abuts against the upper part of the first ankle cup, improving the stability of the support portion. In the folded state of the back plate, the support portion flips towards the base, facilitating the folding and storage of the fixator and reducing space occupation.

[0008] Optionally, an elastic element is provided at the first pivot, the elastic element having an elastic force for driving the back plate to flip backward. With this arrangement, the elastic force of the elastic element allows the back plate to remain in an open, backward-flipped state without any force applied, eliminating the need for hand support during snowshoe insertion and making it easier to put on the snowshoes.

[0009] Optionally, the first strap is rotatably mounted on the vertical plate of the base via a second pivot. The strap is equipped with an adjustment element. In the open state, the first strap is loosened via the adjustment element; in the locked state, the first strap is tightened via the adjustment element. With this configuration, in the open state, the first strap is loosened via the adjustment element, increasing the space for the snowshoe to be worn; in the locked state, the first strap is tightened via the adjustment element, thus locking the first strap to the ankle of the snowshoe.

[0010] Optionally, a concave second ankle cup is provided at the rear end of the vertical plate. This concave second ankle cup connects the two vertical plates on the base into a single unit, increasing the strength of the vertical plates and thus improving the stability of the snowshoe's lateral support.

[0011] Optionally, the upper edge of the second ankle cup is higher than the first pivot, and the difference between the height of the upper edge of the second ankle cup and the height of the first pivot is less than or equal to 2 cm; or, the height of the upper edge of the second ankle cup is the same as the height of the first pivot; or, the upper edge of the second ankle cup is lower than the first pivot. With these settings, when the back panel is flipped open backwards, interference from the second ankle cup with the back panel can be avoided, preventing the back panel from flipping at too small an angle.

[0012] Optionally, the pedal is rotatably disposed between the two side plates. With this arrangement, the pedal or pivot rotates relative to the side plates, allowing the pedal to rotate in coordination with different ski boot angles.

[0013] Optionally, the pedal is provided with a connecting rod, which is rotatably connected to the side plate. With this configuration, the pedal is rotatably connected to the side plate via the connecting rod. The connecting rod increases the distance between the pedal and the first strap, facilitating the entry of the snowshoe into the binding.

[0014] Optionally, the first strap is rotatably mounted on the side plate away from the support via a fourth pivot. In the locked state, the side plate causes the first strap to tighten towards the base. With the above arrangement, the first strap, rotatably connected to the side plate via the fourth pivot, tightens as the ski boot is stepped on, causing the back plate to flip forward. This tightens the first strap, thereby locking the ankle area of ​​the ski boot.

[0015] Optionally, the pedal rotates coaxially with the first strap. This arrangement reduces the number of pivots on the side plate, thereby increasing the strength of the side plate.

[0016] Optionally, the pedal is rotatably mounted on the side plate via a fifth pivot, which is located in the area between the first and fourth pivots on the side plate. This arrangement shortens the distance between the first strap and the pedal during the opening and tightening process, allowing the first strap to press against the ankle and further secure the snowshoe. With this configuration, in the locked state of the back plate, the fifth pivot is positioned rearward relative to the fourth pivot on the side plate, increasing the distance between the pedal and the first strap when the back plate is open, facilitating the insertion of the snowshoe. Furthermore, the fifth pivot of the pedal on the side plate is located on the side of the back plate away from the support, ensuring that the torque required to rotate the back plate around the first pivot is met during pedal application.

[0017] Optionally, the base is provided with a snap-fit ​​structure for locking the pedal or the side plate, thereby locking the back plate and the first strap. With this configuration, when the snowshoe contacts the upper surface of the base, the snap-fit ​​structure can lock the pedal or side plate, thereby locking the back plate and the first strap.

[0018] This utility model provides a ski, comprising: a ski body and a binding device as described in any of the above embodiments, wherein the binding device is fixedly connected to the ski body and the binding device is installed on the ski body. Due to the use of the above-described binding device, it possesses any of the aforementioned advantages. Attached Figure Description

[0042] Example 1

[0043] This embodiment provides a structure for a fastener that enables quick on and off, for quick on and off of snowshoes 17.

[0044] like Figures 1-4 The diagram illustrates a specific embodiment of a binding device provided in this example, comprising: a base 1, a back plate 3, a first strap 8, and a second strap 9. The base 1 is used to mount the device on a ski, and two spaced vertical plates 2 are provided on the base 1. The vertical plates 2 support the sides of the ski boot 17. The back plate 3 is rotatably mounted on the rear of the vertical plates 2 via a first pivot 6. The back plate 3 has a support portion 5 and side plates 4. The side plates 4 extend forward from both sides of the support portion 5, and the base of the support portion 5 extends backward. The first pivot 6 is located in the middle region of the side plates 4, and a footboard 7 is rotatably mounted on the front end of the side plates 4. The first strap 8 is provided with... The first strap 8 is used to secure the ankle of the snowshoe 17, which is placed on the base 1. The second strap 9 is located at the front of the base 1 and is used to secure the toe of the snowshoe 17. In the open state, the back plate 3 flips backward, causing the pedal 7 to flip upward, so that a space is formed between the back plate 3 and the first strap 8 for the snowshoe 17 to enter. In the locked state, the snowshoe 17 steps on the pedal 7 and moves towards the base 1, causing the back plate 3 to rotate. The back plate 3 presses against the back of the lower leg and / or ankle of the snowshoe 17 and pushes the snowshoe 17 toward the front of the base 1, so that the toe of the snowshoe 17 is pressed against the second strap 9.

[0045] In use, in the open state, flipping the back plate 3 backward causes the side plate 4 to flip the pedal 7 upward. The base of the support part 5 extends backward relative to the side plate 4, increasing the space between the back plate 3 and the first strap 8, making it easier for the snowshoe 17 to enter from the space between the back plate 3 and the first strap 8 and step on the pedal 7. In the locked state, as the snowshoe 17 steps towards the base 1, the pedal 7 causes the support part 5 to flip forward. While the support part 5 presses against the back of the lower leg and / or ankle of the snowshoe 17, it pushes the snowshoe 17 towards the front of the base 1 to press against the second strap 9. At the same time, the first strap 8 locks the ankle of the snowshoe 17. This fastener has a simple structure and is compatible with various models of snowshoe 17. The fastener provided by this utility model solves the problems of complex structure and poor compatibility of fasteners in the prior art.

[0046] It should be further noted that the second strap 9 is rotatably connected to the front end of the vertical plate 2 or the base 1, and the second strap 9 can be equipped with an adjustable length structure according to design requirements.

[0047] like Figure 1 , Figure 5 As shown, in the fixator provided in this embodiment, the support part 5 is rotatably mounted on the side plate 4, and a concave first ankle cup 10 is provided at one end of the side plate 4 near the support part 5; the back plate 3 is in an unfolded state, with the base of the support part 5 abutting against the upper part of the first ankle cup 10; the back plate 3 is in a folded state, with the support part 5 flipped towards the front end. The concave first ankle cup 10 connects the two side plates 4 into one unit, which can enhance the strength of the side plates 4. In the unfolded state of the back plate 3, the support part 5 is flipped away from the base 1 so that the base of the support part 5 abuts against the upper part of the first ankle cup 10, which can improve the stability of the support part 5. In the folded state of the back plate 3, the support part 5 is flipped towards the base 1, which can facilitate the folding and storage of the fixator and reduce space occupation. In addition, as an alternative embodiment, the support part 5 and the side plate 4 can also be fixedly connected.

[0048] Specifically, the support part 5 is rotatably connected to the side plate 4 via a third rotating shaft. The third rotating shaft can be set to coincide with the first rotating shaft 6 or to be set to be offset.

[0049] like Figure 1As shown, in the fastener provided in this embodiment, an elastic element is provided at the first pivot 6. The elastic element has an elastic force for driving the back plate 3 to flip backward. Under the action of the elastic force of the elastic element, the back plate 3 remains in an open, backward-flipped state when no force is applied, avoiding the need for hand support during the snowshoe 17 insertion process, thus facilitating the insertion of the snowshoe 17. Specifically, the elastic element can be set as a torsion spring, a spring sheet, or other elastic structure. Alternatively, as an alternative implementation, the elastic element can be omitted, and the back plate 3 can be kept in an open, backward-flipped state by its own weight.

[0050] like Figure 2 , Figure 3 As shown, in the fastener provided in this embodiment, the first strap 8 is rotatably mounted on the vertical plate 2 of the base 1 via the second pivot 11. An adjusting member is provided on the strap. In the open state, the first strap 8 is loosened via the adjusting member; in the locked state, the first strap 8 is tightened via the adjusting member. In the open state, the first strap 8 is loosened via the adjusting member, increasing the space for the snowshoe 17 to be inserted; in the locked state, the first strap 8 is tightened via the adjusting member, so that the first strap 8 is locked to the ankle of the snowshoe 17. Alternatively, as an alternative embodiment, the second pivot 11 can be omitted, and both the first strap 8 and the back plate 3 are rotatably connected to the vertical plate 2 via the first pivot 6.

[0051] like Figure 1 As shown, in the fastener provided in this embodiment, a concave second ankle cup 12 is provided at the rear end of the vertical plate 2. The concave second ankle cup 12 can connect the two vertical plates 2 on the base 1 into one piece, improving the strength of the vertical plate 2 and thus improving the stability of the support for both sides of the snowshoe 17. In addition, as an alternative embodiment, the second ankle cup 12 can be omitted, and the thickness of the vertical plate 2 can be increased, thereby improving the strength of the vertical plate 2.

[0052] like Figure 1 As shown, in the fixation device provided in this embodiment, the upper edge of the second ankle cup 12 is set higher than the first rotating shaft 6, and the difference between the height of the upper edge of the second ankle cup 12 and the height of the first rotating shaft 6 is less than or equal to 2 cm; or, the height of the upper edge of the second ankle cup 12 is flush with the height of the first rotating shaft 6; or, the upper edge of the second ankle cup 12 is set lower than the first rotating shaft 6. When the back plate 3 is flipped open backward, the second ankle cup 12 can be prevented from interfering with the back plate 3, thus avoiding the back plate 3 from having an excessively small flipping angle.

[0053] like Figure 1As shown, in the fastener provided in this embodiment, the pedal 7 is rotatably disposed between the two side plates 4. The pedal 7 rotates relative to the side plates 4, allowing the pedal 7 to rotate and engage with different angles of the snowshoe 17. Specifically, the pedal 7 is disposed between the two side plates 4 via a pivot.

[0054] Specifically, the base 1 is provided with a snap-fit ​​structure 16, which is used to lock the pedal 7 or the side plate 4, thereby locking the back plate 3. When the snowshoe 17 contacts the upper surface of the base 1, the snap-fit ​​structure 16 can lock the pedal 7 or the side plate 4, thereby locking the back plate 3.

[0055] How to use:

[0056] like Figure 1 As shown, in this embodiment, the fastener allows the support portion 5 of the back plate 3 to rotate and unfold during use, causing the back plate 3 to flip backward. The side plate 4 then causes the pedal 7 to flip upward. The snowshoe 17 enters through the space between the back plate 3 and the first strap 8 and steps onto the pedal 7. As the snowshoe 17 steps towards the base 1, the pedal 7, through the side plate 4, causes the support portion 5 to flip forward. While the support portion 5 presses against the back of the lower leg and / or ankle of the snowshoe 17, it pushes the snowshoe 17 towards the front of the base 1 to press against the second strap 9. Simultaneously, the first strap 8 is manually tightened to lock the ankle of the snowshoe 17. This fastener provides a simple structure for quick on and off and is compatible with various snowshoes 17.

[0057] Example 2

[0058] The fixator provided in this embodiment has a structure that is largely the same as that in Embodiment 1, except that:

[0059] like Figures 6-10 As shown in the embodiment, in the fixing device provided, the pedal 7 is provided with a connecting rod 13, and the connecting rod 13 is rotatably connected to the side plate 4. The pedal 7 is rotatably connected to the side plate 4 through the connecting rod 13. The provision of the connecting rod 13 can increase the distance between the pedal 7 and the first strap 8, making it easier for the snowshoe 17 to be put into the fixing device.

[0060] The fastener provided in this embodiment enables quick donning and doffing through a simple structure and is compatible with a variety of snow boots 17.

[0061] Example 3

[0062] The fixator provided in this embodiment has a structure that is largely the same as that in Embodiment 1, except that:

[0063] like Figures 11-13As shown, in the fastener provided in this embodiment, the first strap 8 is rotatably disposed at the end of the side plate 4 away from the support part 5 via the fourth pivot 14. In the locked state, the side plate 4 drives the first strap 8 to tighten towards the base 1. The first strap 8, which is rotatably connected to the side plate 4 via the fourth pivot 14, tightens when the snowshoe 17 is stepped on, as the pedal 7 drives the back plate 3 to flip forward, thereby locking the ankle of the snowshoe 17.

[0064] like Figures 11-13 As shown, in the fastener provided in this embodiment, the pedal 7 rotates coaxially with the first strap 8. This reduces the number of pivots on the side plate 4, thereby increasing the strength of the side plate 4.

[0065] like Figures 11-13 As shown, in the fastener provided in this embodiment, the base 1 is provided with a buckle structure 16, which is used to lock the pedal 7 or the side plate 4, thereby locking the back plate 3 and the first strap 8. With the above configuration, when the snowshoe 17 contacts the upper surface of the base 1, the buckle structure 16 can lock the pedal 7 or the side plate 4, thereby locking the back plate 3 and the first strap 8.

[0066] Specifically, the second ankle cup 12 is not provided at the rear of the side plate 4, and the back plate 3 can be flipped and unfolded at a greater angle, making it easier for the snowshoe 17 to be put on. Alternatively, as an alternative implementation, the second ankle cup 12 can also be provided at the rear of the side plate 4 according to design requirements.

[0067] In use, the back plate 3 is flipped backward, causing the side plate 4 to flip the pedal 7 upward. The snowshoe 17 enters through the space between the back plate 3 and the first strap 8 and is stepped on the pedal 7. As the snowshoe 17 steps towards the base 1, the pedal 7, through the side plate 4, causes the support part 5 to flip forward. While the support part 5 presses against the back of the lower leg and / or ankle of the snowshoe 17, it pushes the snowshoe 17 towards the front of the base 1 to press against the second strap 9. At the same time, the side plate 4 causes the first strap 8 to tighten, thus locking the ankle of the snowshoe 17. The fastener provided in this embodiment achieves quick on and off through a simple structure and is compatible with various snowshoes 17.

[0068] Example 4

[0069] The fixator provided in this embodiment has a structure that is largely the same as that in embodiment 3, except that:

[0070] like Figures 14-16As shown, in the fastener provided in this embodiment, the pedal 7 is rotatably mounted on the side plate 4 via a fifth pivot 15. The fifth pivot 15 is located on the side plate 4 in the area between the first pivot 6 and the fourth pivot 14, so that during the opening to tightening process, the distance between the first strap 8 and the pedal 7 is shortened, thereby tightening the first strap 8 against the ankle and further securing the snowshoe 17. In the locked state of the back plate 3, the fifth pivot 15 is positioned rearward on the side plate 4 relative to the fourth pivot 14, which increases the distance between the pedal 7 and the first strap 8 when the back plate 3 is open, making it easier to put on the snowshoe 17. On the side plate 4, the fifth pivot 15 of the pedal 7 is located on the side of the back plate 3 away from the support part 5, ensuring that during the pedal 7 being stepped on, the torque requirement is met to drive the back plate 3 to rotate around the first pivot 6.

[0071] In use, the back plate 3 is flipped backward, causing the side plate 4 to flip the pedal 7 upward. The snowshoe 17 enters through the space between the back plate 3 and the first strap 8 and is stepped on the pedal 7. As the snowshoe 17 steps towards the base 1, the pedal 7, through the side plate 4, causes the support part 5 to flip forward. While the support part 5 presses against the back of the lower leg and / or ankle of the snowshoe 17, it pushes the snowshoe 17 towards the front of the base 1 to press against the second strap 9. At the same time, the side plate 4 causes the first strap 8 to tighten, thus locking the ankle of the snowshoe 17. The fastener provided in this embodiment achieves quick on and off through a simple structure and is compatible with various snowshoes 17.

[0073] This embodiment also provides a ski, including: a ski body and the bindings described in the above embodiments, wherein the base of the bindings is fixedly connected to the ski body. The bindings described in the above embodiments enable quick on and off.

[0074] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
