Description

Quick dismounting and locking system of ice skate blade TECHNICAL FIELD

[0001] The present application relates to the field of ice skating equipment, in particular to a quick dismounting and locking system of ice skate blade. BACKGROUND

[0002] Ice skating is a sport that uses ice skates to walk or race on ice. Various large-scale sports events have multiple ice skating events, such as short track speed skating, speed skating, and performance events such as figure skating. In addition, curling and ice hockey have become popular events on the field in recent years. Countries are actively promoting public participation in various ice sports and promoting the popularization and development of the sport.

[0003] In existing ice sports, due to high-speed skating and intense competition, the wear and tear of the ice skate blade has a significant impact on the sport. In particular, for sports such as ice hockey and figure skating, which have relatively short and large longitudinal curvature ice skate blades, whether the ice skate blade is in the best condition is crucial to the performance of the athlete. Therefore, in the field of ice hockey or figure skating, a detachable ice skate shoe that can quickly sharpen or replace the ice skate blade during the game interval to ensure its sharpness and performance has become the best choice to solve this problem.

[0004] However, due to the short time interval between games, quickly replacing the ice skate blade has become a major problem. Existing ice skate replacement mechanisms are cumbersome and labor-intensive, and there are certain safety hazards. For example, in ice hockey and curling games, athletes usually wear thick protective equipment and thick gloves, making it very difficult to remove the ice skate blade. If the protective equipment is removed to replace the ice skate blade during the game interval, not only will it affect the effectiveness of the protective equipment, but it will also waste valuable game time.

[0005] In addition, the existing ice skate shoes on the market often accumulate ice slag between the ice skate blade and the blade slot after a long time of skating, making it difficult to remove the ice skate blade. For athletes wearing gloves and protective equipment, this is extremely inconvenient when replacing the ice skate blade in a short period of time. Therefore, how to design an ice skate dismounting system that is easy to operate and quick has become a problem that needs to be solved in the current ice skating equipment field. SUMMARY

[0006] The purpose of the present application is to provide a more efficient, safer, and more durable quick dismounting and locking system of ice skate blade.

[0007] In order to achieve the above purpose, the present application adopts the following scheme: a quick dismounting and locking system of ice skate blade, comprising:

[0008] The blade holder is connected to the sole, and the bottom of the blade holder is provided with a blade slot capable of inserting the ice skate blade. A fixing clamping point is arranged at one end of the blade slot for clamping the hook A of one end of the ice skate blade. A hook slot is arranged at the other end of the blade slot for accommodating the hook B of the other end of the ice skate blade.

[0009] The ice skate blade locking hook is rotatably installed in the blade holder, and the bottom end of the ice skate blade locking hook extends into the hook slot and is hooked with the hook B of the ice skate blade inserted into the hook slot.

[0010] The locking hook driving member is connected to the ice skate blade locking hook and is slidably arranged in the blade holder. By sliding the locking hook driving member, the ice skate blade locking hook is driven to flip, thereby releasing the hooking connection between the ice skate blade locking hook and the hook B.

[0011] The reset member is arranged in the blade holder and is used to reset the ice skate blade locking hook after it is flipped by the locking hook driving member.

[0012] The ice skate blade locking hook is hooked with the hook B through rotation, providing a stable locking mechanism. This design ensures that the ice skate blade can be firmly fixed on the blade holder during high-speed sliding and intense competition, avoiding the risk of movement caused by loose ice skate blades. The design simplifies the operation process, improves the stability and safety of the ice skate blade mounting and dismounting system, meets the requirements of the competition environment, and fully solves the problems of complicated and laborious operation, safety hazards, and other issues in the traditional ice skate blade replacement process. By sliding the locking hook driving member to control the flipping of the ice skate blade locking hook, the ice skate blade can be quickly fixed and released. The reset member automatically restores the ice skate blade locking hook to the initial position, significantly improving the efficiency of blade replacement and the consistency of the system. This helps athletes quickly replace their ice skate blades during breaks, ensuring their best performance.

[0013] As a further aspect of the present application, the blade holder is provided with a receiving cavity in communication with the hook slot at a position connected to the rear heel of the sole, and the skate blade lock hook and the reset member are arranged in the receiving cavity, thereby providing a closed and protected environment and reducing the interference of external factors on the locking system. This design effectively avoids the entry of foreign matter such as ice shavings into the locking mechanism, ensuring that the skate blade can still be smoothly disassembled after a long time of sliding. A connecting boss is arranged in the receiving cavity behind the skate blade lock hook, the connecting boss is hollow, and the left and right ends of the connecting boss are connected to the left and right inner walls of the receiving cavity, respectively. An operation hole is arranged on each of the left and right side walls of the blade holder, and the operation hole is in communication with the hollow inner cavity of the connecting boss. A guide slot is arranged in the receiving cavity and penetrates the outer wall of the connecting boss. The lock hook driving member is slidingly inserted into the guide slot, the front end of the lock hook driving member is movably connected to the skate blade lock hook, and the tail of the lock hook driving member is exposed through the operation hole. The connecting boss and the guide slot provide a stable support platform for the lock hook driving member, so that the lock hook driving member can smoothly slide in the guide slot. The user can directly control the sliding of the lock hook driving member through the operation hole, thereby controlling the hooking of the skate blade lock hook and the hook B through rotation, enhancing the overall operation flexibility of the skate blade disassembly and locking system and simplifying the entire operation process.

[0014] As a preferred aspect of the present application, the lock hook driving member includes a pulling lever portion and a pulling rod portion. The pulling lever portion is inserted into the guide slot, the pulling rod portion is connected to the front end of the pulling lever portion, the front end of the pulling rod portion extends to the front side of the skate blade lock hook, and a pulling point is arranged at the front end of the pulling rod portion for hooking the front side wall of the skate blade lock hook. The tail end of the pulling lever portion extends downward into the inner cavity of the connecting boss, and a pressing portion is arranged on the front side edge of the pulling lever portion. The pressing portion can be exposed from the operation hole and has a gap with the front side inner wall of the inner cavity of the connecting boss. The pulling rod portion and the pulling lever portion are integrally formed.

[0015] The design of the locking hook driving member in the above scheme further enhances the functionality and user-friendliness of the quick disassembly and locking system of the ice skate by introducing an integrated structure of the pull rod part and the pulling part and the exposed operation design of the pressing part. The pulling part is inserted into the guide groove, allowing the locking hook driving member to slide forward and backward in a fixed track. This design ensures stable guidance of the locking hook driving member during sliding, thereby avoiding sliding deviation. The front end of the pull rod part extends to the front side of the ice skate locking hook and is connected to the front side wall of the ice skate locking hook through a pull point. This design can precisely control the flipping and locking of the ice skate locking hook through forward and backward sliding of the locking hook driving member, ensuring that the ice skate can be quickly and stably installed or disassembled. Second, the pressing part is exposed through the operation hole, providing an intuitive operation interface. Users only need to press the pressing part to achieve sliding control of the locking hook driving member. This design greatly simplifies the operation steps, and even in the case of wearing thick gloves, the user can complete the quick disassembly and assembly of the ice skate through simple pressing actions, improving the convenience of use. In addition, there is a gap between the pressing part and the front side inner wall of the connecting boss inner cavity, ensuring that the pressing part has enough operating space when pressed. The pull rod part and the pulling part are integrally formed. This structural design not only improves the overall strength and stability of the components, but also enables the entire locking hook driving member to achieve efficient driving function in a limited space.

[0016] As a preferred aspect of the present application, opposite symmetrical hinge shaft seats are respectively provided on the inner walls of the accommodating cavity located in front of the connecting boss. The top end of the ice skate locking hook is hinged to the hinge shaft seats through a hinge shaft, providing stable support for the hinge of the ice skate locking hook. The reset member includes a torsional spring sleeved on the hinge shaft or a spring arranged between the front side wall of the connecting boss and the rear side wall of the ice skate locking hook. The design of the torsional spring utilizes the characteristics of rotational elastic force. After the ice skate locking hook completes the flipping action, it can automatically return to the initial state, ensuring the reset stability of the locking hook after each operation. The design of the spring utilizes the axial elastic restoring force to quickly restore the ice skate locking hook to the locked position when the locking hook driving member no longer applies external force. The torsional spring or spring can be selected according to actual use to achieve reset of the ice skate locking hook, to adapt to different operation requirements and environmental conditions.

[0017] As a further aspect of the present application, a cover plate is provided on the top of the connecting boss to prevent the locking hook driving member from being pulled out of the guide groove upward.

[0018] As a preferred form of the present application, a clearance passage is formed through the central part of the pull rod portion downwardly, and the bottom end of the skate hook extends downwardly through the clearance passage. A rearward guiding slope is formed on the front side wall surface of the skate hook below the hinge shaft, and the outer wall of the pull point abuts against the guiding slope. The guiding slope further improves the cooperation efficiency between the skate hook and the pull point. The guiding slope enables the pull point to smoothly contact the surface of the skate hook and slide along the slope. This design not only enables the pull point to smoothly engage with the skate hook, but also reduces the resistance in the process of driving the skate hook to flip over through the guiding effect of the slope, so that the whole operation is more labor-saving and smooth. This structural design is particularly important for athletes to quickly replace skates during the competition, because it reduces the power and time required for operation, and helps to complete the disassembly and assembly of the skates within a short interval of the competition.

[0019] As a further form of the present application, a triangular protruding portion is formed on the top of the tail end of the skate near the clamping hook B, and a communication groove is formed in the bottom of the inner cavity of the connecting boss and communicates with the skate slot. The protruding portion can be inserted into the communication groove. A skate releasing block is formed at the bottom end of the pulling portion and can be inserted into the communication groove. A pressing slope is formed on the rear side of the skate releasing block and can press the front side slope of the protruding portion. The combination of the skate releasing block and the pressing slope and the triangular protruding portion provides a simple and efficient skate unlocking mechanism. When it is necessary to replace the skate, the skate releasing block enters the communication groove and contacts the protruding portion by sliding the pulling portion. Due to the triangular structure of the protruding portion, the pressing slope can smoothly slide along the front side slope of the protruding portion, thereby producing a pressing effect to quickly push the skate out of the skate slot, effectively solving the problem of accumulated ice slag causing the skate to be difficult to pull out.

[0020] As a further form of the present application, a clamping hook C is formed on the top of the skate between the protruding portion and the clamping hook B and protrudes upwardly and can be inserted into the communication groove. A hook block is formed on the front side of the skate releasing block and extends forwardly. When the pulling portion is moved forwardly, the hook block and the clamping hook C are hooked together. When the pulling portion is pressed to move backwardly, the hook block and the clamping hook C are disengaged. In addition to the clamping hook B being hooked with the clamping hook C to lock the skate by rotating, the hook block and the clamping hook C are hooked together, which means that the skate can be more firmly locked in the skate slot to ensure that it does not loosen or fall off during the movement. When it is necessary to replace or adjust the skate, the pulling portion is pressed to move backwardly, and the hook block and the clamping hook C are disengaged. This process further ensures the firmness and reliability of the skate lock, while still simplifying the quick disassembly steps of the skate. The athlete only needs to perform a simple sliding action of the pulling portion to complete the locking or unlocking operation of the skate. Higher operation efficiency and safety are provided.

[0021] As a further aspect of the present application, the tail end of the hook driving member is provided with an elastic member for returning the hook driving member to the front end position after the hook driving member is moved backward.

[0022] As a preferred aspect of the present application, the elastic member comprises an elastic arm extending obliquely from the tail end of the hook driving member, an acute angle is formed between the elastic arm and the tail end of the hook driving member, and the end of the elastic arm abuts against the inner wall of the tail end of the accommodating cavity. The provision of the elastic arm ensures that the hook driving member can quickly and reliably return to the initial position after being operated. The elastic arm in the elastic member extends obliquely from the tail end of the hook driving member and forms an acute angle. This structure enables the elastic arm to generate sufficient elastic force to push the hook driving member to return when subjected to external force.

[0023] In summary, the present application has the following advantages over the prior art: the present application proposes a quick disassembly and locking system for ice skates, which effectively solves the problems of complicated operation, great safety hazards, and difficulty in quickly replacing ice skates in the existing ice skate disassembly system. First, by designing the fixing structure of the skate holder and the ice skate, the ice skate can be securely clamped into the skate slot and locked by the hooking of the ice skate hook and the hook B, ensuring the stability of the ice skate during sliding. At the same time, the combination of the hook driving member and the reset member enables the ice skate hook to automatically reset after operation, improving the reliability of the locking and simplifying the operation process. In particular, by providing operation holes on both sides of the skate holder, the user can easily slide the hook driving member to achieve quick disassembly and locking of the ice skate. This design significantly simplifies the operation steps, and the user can quickly replace the ice skate even when wearing gloves.

[0024] On this basis, the hook driving member is designed to be integrally formed by the pulling part and the pull rod part, making the operation more flexible and smooth, and reducing the possibility of jamming during operation. In addition, the elastic member at the tail end of the hook driving member ensures its automatic resetting function after operation, further improving the reliability and durability of the system. In order to prevent the ice skate from sliding or falling off during use, the combination of the retreat block and the extrusion inclined surface in the quick disassembly and locking system for ice skates is designed to cooperate with the triangular protruding part on the ice skate. By extrusion, the ice skate can be quickly pushed out of the skate slot, effectively solving the problem of accumulated ice slag causing the ice skate to be difficult to pull out. The further optimized design of the hook block and the hook C on the retreat block can be connected together or separated during the forward and backward movement of the hook driving member, further ensuring the stability and ease of use of the ice skate during disassembly and use, reducing the risk of accidental falling. This comprehensive design not only improves the operation convenience of the system, but also significantly enhances the safety and performance stability of the athlete during high-speed sliding or competition.

[0025] Therefore, the application successfully overcomes many deficiencies in the prior art by comprehensively optimizing the structural design of the skate blade locking and dismounting, and provides a more efficient, safer and more durable skate blade quick dismounting solution.

Therefore, the features defined as "first" and "second" can include one or more features explicitly or implicitly.

[0041] The present application will be further described below in conjunction with the accompanying drawings and specific embodiments: as shown in FIGS. 1-13, a quick disassembly and locking system for a skate blade includes a blade holder 1 fixedly connected to the sole of a skate, the bottom of the blade holder 1 is provided with a blade slot 11 for inserting and fixing a skate blade 2. A fixed clamping point 12 is provided at one end of the blade slot 11 for clamping a hook A21 at one end of the skate blade 2, and a hook slot 13 is provided at the other end of the blade slot 11 for accommodating a hook B22 at the other end of the skate blade 2, to ensure that the top of the skate blade 2 can be completely inserted into the blade slot 11 and fixed securely. In order to achieve quick disassembly of the skate blade, a receiving cavity 14 is provided in the blade holder 1 at a position connected to the rear heel of the sole, which is in communication with the hook slot 13, and a skate blade locking hook 3 is rotatably installed in the receiving cavity 14. Specifically, opposite symmetrical hinge shaft seats 18 are provided horizontally on the inner wall of the receiving cavity 14, and the top end of the skate blade locking hook 3 is hinged to the hinge shaft seats 18 through left and right extending hinge shafts 32, and the bottom end of the skate blade locking hook 3 extends downward into the hook slot 13 and hooks with the hook B22 inserted into the slot, to lock the skate blade 2 so that it cannot be separated from the blade slot 11. The flipping action of the skate blade locking hook 3 is controlled by a hook driving member 4 which is slidingly arranged in the receiving cavity 14, and by pushing or pulling the hook driving member 4, the rotation of the skate blade locking hook 3 can be achieved, thereby releasing the hooking with the hook B22 and achieving the purpose of quick disassembly of the skate blade.

[0042] During the sliding of the lock hook driving member 4, the reset member 5 provided in the accommodating cavity 14 can restore the ice skate lock hook 3 to the locking state after the lock hook driving member 4 completes the rotating action and can indirectly reset the lock hook driving member 4. The reset member 5 in this embodiment is preferably in the form of a torsion spring or a spring sleeved on the hinge shaft 32 and is installed in the accommodating cavity 14 to ensure that the lock hook driving member 4 can be stably reset. Of course, a straight spring design can also be adopted, and the elastic restoring force of the straight spring in the axial direction is used to restore the ice skate lock hook 3 to the forward state after completing the rotating action. Specifically, a connecting boss 17 is provided in the accommodating cavity 14 behind the ice skate lock hook 3, the connecting boss 17 is hollow, and the left and right ends of the connecting boss 17 are connected to the left and right inner walls of the accommodating cavity 14, respectively. The straight spring is abutted between the front side wall of the connecting boss 17 and the rear side wall of the ice skate lock hook 3.

[0043] In order to facilitate operation, the two sides of the blade holder 1 are provided with operation holes 16, through which the user can directly control the locking hook driving member 4. The two operation holes 16 are respectively connected with the hollow inner cavity of the connecting boss 17, and the outer wall in the center of the connecting boss 17 is provided with a guide groove 15 extending from front to back and from top to bottom, the locking hook driving member 4 is inserted in the boss 17 through the guide groove 15 to achieve sliding control. In this embodiment, the locking hook driving member 4 includes a pulling part 41 inserted in the guide groove 15 and a pull rod part 42 integrally formed with the pulling part 41, the front end of the pull rod part 42 extends to the front side of the ice skate blade locking hook 3 and is provided with a pull point 43, which can hook the front side wall of the ice skate blade locking hook 3. It should be noted that the central part of the pull rod part 42 is provided with a clearance passage 421 extending downward, so that the bottom end of the ice skate blade locking hook 3 can extend downward through the clearance passage 421. In order to enable the pull point 43 to stably engage with the ice skate blade locking hook 3 and reduce the resistance encountered during the pulling process of the ice skate blade locking hook 3, the entire operation is more labor-saving and smooth, a guide inclined surface 31 inclined rearward is arranged on the front side wall surface of the ice skate blade locking hook 3 below the hinge shaft 32, and the outer wall of the pull point 43 abuts against the guide inclined surface 31. The guide inclined surface 31 further improves the cooperation efficiency between the ice skate blade locking hook 3 and the pull point 43. Through the guiding action of the guide inclined surface 31, the pull point 43 can smoothly contact the surface of the ice skate blade locking hook 3 and slide along the inclined surface. In addition, in order to facilitate user operation, a pressing part 44 is further arranged on the front side edge of the pulling part 41, the pressing part 44 is exposed through the operation hole 16, and there is a gap between the pressing part 44 exposed from the operation hole 16 and the front side inner wall of the inner cavity of the connecting boss 17. In order to prevent the locking hook driving member 4 from being separated upward from the guide groove 15, a cover plate 6 is arranged on the top of the connecting boss 17 to increase the stability of the locking hook driving member 4 during movement. Specifically, the front side of the connecting boss 17 located on the left and right sides of the guide groove 15 is provided with a fixed table 19 connected with the inner wall of the accommodating cavity 14 and the outer wall of the connecting boss 17, respectively, the cover plate 6 covers the guide groove 15 in a plate shape and is fastened with the fixed table 19 by penetrating screws.

[0044] In addition, in order to solve the problem that the ice skate 2 is difficult to pull out due to the accumulation of ice shavings between the ice skate 2 and the blade slot 11 during skating. A protruding part 23 in the shape of a triangle protruding upward is arranged at the top of the tail end of the ice skate 2 close to the hook B22, and a communication groove 10 is arranged in the inner cavity of the connecting boss 17 and communicates with the blade slot 11. The protruding part 23 can be inserted into the communication groove 10 when the ice skate 2 is inserted into the blade slot 11. A blade pulling-out block 45 is arranged at the bottom end of the pulling part 41 and can be inserted into the communication groove 10. The rear side of the blade pulling-out block 45 is provided with a pressing slope 46 which can press the front side slope of the protruding part 23. When the pulling part 41 moves backward, the pressing slope 46 of the blade pulling-out block 45 can press the protruding part 23, and the tail end of the ice skate 2 is pushed out of the blade slot 11, which is convenient and fast.

[0045] In order to further improve and ensure the firm locking effect of the ice skate 2, a hook C24 protruding upward and capable of being inserted into the communication groove 10 is arranged at the top of the ice skate 2 between the protruding part 23 and the hook B22, and a hook block 47 extending forward is arranged at the front side of the blade pulling-out block 45. When the pulling part 41 moves forward, the hook block 47 and the hook C24 are connected with each other, the hook block 47 and the hook C24 are firmly clamped, and the locking safety of the ice skate is further improved. When the pulling part 41 is pressed to move backward, the hook block 47 and the hook C24 are disconnected, which is simple and fast and does not need to increase a complex mechanism. In order to prevent the hook block 47 and the hook C24 from blocking each other when the ice skate 2 is inserted into the blade slot 11, the end of the hook block 47 and the end of the hook C24 are provided with mismatched slopes 8 which can cooperate with each other. When the hook A21 at the front end of the ice skate 2 is clamped into the fixed clamping point 12, the mismatched slope 8 on the hook C24 presses the mismatched slope 8 on the hook block 47 when the tail end of the ice skate 2 is rotated upward and inserted into the blade slot 11, so as to push and displace the whole locking hook driving part 4 backward. When the end of the hook block 47 and the end of the hook C24 are staggered, the tail end of the blade slot 11 can be pushed upward again. It should be noted that the installation of the ice skate also needs to be fast, so the end of the hook block 47 and the top of the hook B22 at the other end of the ice skate 2 are provided with guide slopes 9 which can cooperate with each other when the end of the hook block 47 and the top of the hook B22 contact each other. When the hook B22 is inserted into the hook slot 13, the guide slope 9 at the top of the hook B22 presses the guide slope 9 at the bottom end of the ice skate hook 3, so that the ice skate hook 3 is turned backward, and the function that the ice skate hook 3 is automatically hooked on the hook B22 is realized by cooperating with the reset part 5, without manually turning the ice skate hook 3 in advance. The ice skate 2 can be automatically locked by pressing the tail end of the ice skate 2 into the blade slot 11 after the hook A21 at the front end of the ice skate 2 is clamped into the fixed clamping point 12.

[0046] In addition, as shown in Figs. 3 to 12, in order to ensure that the hook driving member 4 can quickly and reliably return to the initial position after being operated, the tail end of the hook driving member 4 is provided with an elastic member 7, which is composed of an elastic arm 71 integrally and obliquely extended from the tail end of the pulling part 41. The elastic arm 71 forms an acute angle with the tail end of the hook driving member 4, and a collapse groove 72 is arranged at the position of the acute angle. The end of the elastic arm 71 abuts against the inner wall of the tail end of the accommodating cavity 14. When the hook driving member 4 moves backward, the elastic arm 71 can generate a counterforce to reset the hook driving member 4 to the front end position, ensuring that the device can recover to the initial state after each operation and be ready for the next operation.

[0047] As shown in Fig. 13, another embodiment of the elastic member 7 is basically the same as the first embodiment, and only the elastic arm 71 is changed to a spring abutting between the tail end of the pulling part 41 and the inner wall of the tail end of the accommodating cavity 14.
