Description

An integrated structure of sole and blade holder and ice skates Technical Field

[0001] The present invention relates to the field of ice skate accessories, and in particular to an integrated sole and blade support structure and an ice skate. Background Art

[0002] At present, ice skates used worldwide are mainly divided into two structures: one-piece and split-piece. One-piece ice skates are heavy and cannot meet the technical requirements of figure skates, and have lost their market competitiveness. The blade holders of split ice skates are often connected by arc welding, brazing, fasteners or special-shaped materials, but there are safety hazards and high manufacturing costs. At present, EU standards and Chinese national standards have put forward strict safety and technical requirements for all-metal water jets, but only a few processes can meet the requirements, resulting in high production costs and low output. Among them, the split ice skates use arc welding, brazing or special-shaped material connections to make the blade holder, and then use screws and other fasteners to install the blade holder on the sole. This traditional manufacturing method has problems to varying degrees, especially when welding two steels of different properties, the welding performance is poor and the required degree of rigidity cannot be achieved. The most important thing is that due to the vibrations caused by athletes in violent movements such as sliding, jumping and rotating, the way of connecting the knife holder to the sole through fasteners such as screws can easily lead to a decrease in component strength and the screws can easily become loose or the mating parts can become deformed and loose. After a period of use, the screws and the materials of the connection parts are also prone to fatigue, resulting in a decrease in the strength of the connection, which can cause the knife holder to loosen or the blade to fall off, seriously affecting the safety of the athletes.

[0003] Chinese Patent Publication No. CN105214297B discloses a composite ice skate stand. The composite ice skate stand comprises a stand body, comprising a shoe frame and a blade holder. The shoe frame comprises a toe support, a heel support, and a connecting strip for connecting the toe and heel supports. The shoe frame is constructed of carbon fiber, while the blade holder is constructed of plastic. The blade holder and shoe frame are cast and fixed together. The connecting strip has a concave cross-section. The bottom surface of the shoe frame is a receiving groove with a plurality of connection holes spaced apart at intervals. The groove is filled with a pressure plate, which is integrally formed with the blade holder. This invention patent is formed by pouring and connecting a shoe frame made of carbon fiber and a knife holder made of plastic. Although it can solve the problem of using complex processes such as arc welding and brazing to manufacture the knife holder with a water jet with an all-metal structure, the thermal expansion coefficients of the plastic and carbon fiber used are different. When the temperature of the two materials changes, their expansion coefficients are also different, and the physical properties will change, which can easily lead to deformation or stress concentration at the connection, thereby causing the connection to separate or break. Especially after strenuous exercise, the risk of cracking and separation between the shoe frame and the knife holder that make up the knife holder is greatly increased.

[0004] In addition, since the sports involved in ice skates require great explosive power at the moment when the athlete pushes off the ice, and the moment of taking off and landing will also generate great shock force, in order to comply with the biomechanical characteristics of human movement, the invention patent claims that the technical solution recorded therein can achieve the effect of increasing the cushioning and energy storage of the shoe frame at the moment when the ice skates slide out, and improving the speed skating performance of the ice skates. In fact, such effects all come from the elastic deformation generated by the shoe frame after being subjected to force. Such deformation also makes it easy for shear force or torque force to be generated between the shoe frame and the blade holder during movement, thereby causing the connection to separate or break. In addition, the recoil force and cushioning capacity provided by the deformation of the shoe frame itself are actually very weak, and cannot truly achieve the boost provided by the recoil force to the athlete's explosive power at the moment of pushing off the ice. Therefore, it is not optimistic about improving the speed skating performance of ice skates, and the shock absorption effect is also mediocre.

[0005] Therefore, it is necessary to develop a new blade support structure and ice skates to solve the existing problems. Summary of the Invention

[0006] The purpose of the present invention is to provide an integrated structure of an ice skate sole and a blade rest, and an ice skate shoe, which can truly buffer and store energy against the pressure applied from the foot while increasing the elasticity and toughness of the blade rest, ensuring the overall supporting strength of the blade rest and the firmness between the blade rest and the shoe body.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following scheme: an integrated structure of a sole and a blade holder, including an integrally formed blade holder and a sole, a blade groove for inserting the blade of an ice skate is provided at the bottom of the blade holder, and an elastic member for cushioning the sole and / or heel is provided on the sole.

[0008] As a further solution of the present invention, the elastic member and the integrally formed knife rest and shoe sole are made of carbon fiber material. The knife rest and shoe sole made of carbon fiber material are lighter, and the elastic member made of carbon fiber material can also be lighter and thinner.

[0009] As a preferred solution of the present invention, the elastic member includes a rear elastic piece extending obliquely upward from the top surface of the sole to above the top surface where the heel of the sole is located. The angle between the bottom surface of the rear elastic piece and the top surface where the heel of the sole is located is an acute angle, so that the rear elastic piece can float up and down after being subjected to force.

[0010] As a preferred solution of the present invention, the elastic member includes a front elastic piece extending obliquely upward from the top surface of the sole to above the top surface of the sole where the sole of the foot is located. The angle between the bottom surface of the front elastic piece and the top surface of the sole where the sole of the foot is located is an acute angle, so that the front elastic piece can float up and down after being subjected to force.

[0011] As a preferred embodiment of the present invention, the elastic member includes a rear elastic piece extending obliquely upward from the top surface of the sole to above the top surface where the heel of the sole is located, and a front elastic piece extending obliquely upward from the top surface of the sole to above the top surface where the sole of the foot is located, the angle between the bottom surface of the rear elastic piece and the top surface where the heel of the sole is located is an acute angle, and the angle between the bottom surface of the front elastic piece and the top surface where the sole of the foot is located is an acute angle.

[0012] As a preferred solution of the present invention, a rear support piece is bent downward or upward from one end of the rear elastic piece, and the angle between the rear support piece and the rear elastic piece is an acute angle.

[0013] As a preferred solution of the present invention, a front supporting piece is bent downward or upward from one end of the front elastic piece, and the angle between the front supporting piece and the front elastic piece is an acute angle.

[0014] As a preferred solution of the present invention, a rear support piece is provided by bending downward or upward from one end of the rear elastic piece, and the angle between the rear support piece and the rear elastic piece is acute. A front support piece is provided by bending downward or upward from one end of the front elastic piece, and the angle between the front support piece and the front elastic piece is acute.

[0015] As a preferred solution of the present invention, a rear separation groove with an opening at one end is provided in the center of the rear support plate. The rear separation groove can more accurately divide the rear support plate into two unloading positions to adapt to different force-generating parts of the foot.

[0016] As a preferred solution of the present invention, a front separation groove with an opening at one end is provided in the center of the front support plate. The front separation groove can more accurately divide the front support plate into two unloading positions to adapt to different force-generating parts of the foot.

[0017] The present invention also provides an ice skate shoe, comprising the above-mentioned sole and blade support integrated structure, wherein the shoe body is connected to the sole.

[0018] As a preferred solution of the present invention, downwardly extending posts and multiple screw holes are respectively provided at the heel position and the sole position under the shoe body, and positioning holes corresponding to the posts and through holes corresponding to the screw holes are respectively penetrated on the sole. The posts are inserted into the corresponding positioning holes, and screws are passed through the through holes to connect with the corresponding screw holes.

[0019] In summary, the beneficial effects of the present invention compared with the prior art are as follows: the present invention utilizes a blade holder and a sole integrally formed of carbon fiber material and adds an upturned elastic part to the sole, which can effectively solve the problem that the blade holder and the sole of traditional ice skates have a small contact area, and due to the vibration of athletes during violent movements such as sliding, jumping and rotating, the blade holder and the sole are connected by fasteners such as screws, which easily leads to a decrease in component strength and the screws are prone to loosening or the mating parts are deformed and loosened. After a period of use, the screws and the materials of the connection parts are also prone to fatigue, resulting in a decrease in the strength of the connection, which leads to the loosening of the blade holder or the falling off of the blade, seriously affecting the safety of the athletes. The high hardness and high elasticity of the carbon fiber material can make the integrally formed sole and the blade holder more firm, and have a certain elastic buffering capacity. Combined with the elastic part also made of carbon fiber, it can provide greater explosive power at the moment when the athlete pushes off the ice, and the vibration force will also be buffered at the moment of taking off and landing, which is more in line with the biomechanical characteristics of human movement.

The terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0035] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods: As shown in Figures 1 to 10, an integrated structure of a sole and a knife holder includes an integrally formed knife holder 1 and a sole 2. A knife groove 11 is provided at the bottom of the knife holder 1 for inserting the ice skate blade 3. The knife holder 1 is hollowed out at the center of the foot and the sole of the foot where it is connected to the sole 2, which can provide a certain degree of elasticity for the sole 2. An elastic member 4 is provided on the sole 2 for cushioning the sole and / or heel. The elastic member 4 and the integrally formed blade rest 1 and the sole 2 are made of carbon fiber material, which can effectively solve the problem that the blade rest and the sole of traditional ice skates have a small contact area, and due to the vibration of athletes in violent movements such as sliding, jumping and rotating, the blade rest and the sole are connected by fasteners such as screws, which easily leads to a decrease in component strength and the screws are prone to loosening or deformation and loosening of the mating parts. After a period of use, the screws and the materials of the connection parts are also prone to fatigue, resulting in a decrease in the strength of the connection, which leads to the loosening of the blade rest or the falling off of the blade, seriously affecting the safety of the athletes. The high hardness and high elasticity of the carbon fiber material can make the integrally formed sole 2 and the blade rest 1 more firm and have a certain cushioning capacity. Together with the elastic member 4, it can provide greater explosive power at the moment when the athlete pushes off the ice, and the vibration force can also be cushioned at the moment of taking off and landing, which is more in line with the biomechanical characteristics of human movement.

[0036] Among them, as shown in Figures 2 to 3, there is a first embodiment of the integrated structure of the sole and the knife holder in the present invention. For figure skaters, the points where the force is applied to their feet during rotation, jumping, and landing involve both the sole and the heel. Therefore, when used for figure skating, the elastic member 4 can be composed of a rear elastic piece 41 extending obliquely upward from the center of the top surface of the sole 2 to above the top surface where the heel of the sole 2 is located, and a front elastic piece 42 extending obliquely upward from the center of the top surface of the sole 2 to above the top surface where the sole of the foot is located. The angle between the bottom surface of the rear elastic piece 41 and the top surface where the heel of the sole 2 is located is an acute angle, and the angle between the bottom surface of the front elastic piece 42 and the top surface where the sole of the foot is located is an acute angle. Here, the elastic member 4 and the sole 2 are integrally formed of carbon fiber material. When pressure is applied to the rear elastic sheet 41 or the front elastic sheet 42, the rear elastic sheet 41 or the front elastic sheet 42 can be allowed to sink. The high elasticity of the carbon fiber material allows the elastic sheet 41 or the front elastic sheet 42 to rebound, providing effective support and resilience to the foot. Of course, in this embodiment, the elastic member 4 can also be made of a single piece of carbon fiber sheet, as shown in Figure 1, that is separate from the sole 2 and has the same contour as the sole 2. When the elastic member 4 and the sole 2 are separate, the elastic member 4 and the sole 2 can be connected together by a screw 6, as shown in Figure 1. Specifically, a countersunk hole 61 is provided in the center of the elastic member 4, and a boss 23 is provided in the center of the sole 2. The boss 23 is inserted into the countersunk hole 61. A connecting hole 24 with an internal thread is provided in the center of the boss 23. The driving end of the screw 6 is inserted from top to bottom and threaded into the connecting hole 24. The connection between the elastic member 4 and the sole 2 can also be directly integrally formed with the top surface of the sole 2, so that the elastic member 4 does not move during strenuous exercise. The front elastic sheet 42 and the rear elastic sheet 41 corresponding to the forefoot and the heel can effectively cushion the shock when the figure skater falls after jumping.

[0037] In addition, in order to accommodate heavier individuals and provide stronger elastic cushioning performance, a second embodiment of the integrated structure of the sole and the knife support of the present invention is shown in Figures 4 and 5. A front elastic sheet 42 extends obliquely upward from the center of the top surface of the sole 2 to the top surface where the sole of the foot is located. A front support sheet 44 is bent upward and extends from one end of the front elastic sheet 42. The angle between the front support sheet 44 and the front elastic sheet 42 is acute. For heavier individuals or those requiring stronger cushioning, the bent front support sheet 44 and the front elastic sheet 42 can form a greater elastic cushioning capacity. Of course, the front support sheet 44 can also be bent downward to form a shape. When the front support sheet 44 is bent downward to form a shape, the end of the front support sheet 44 abuts against the top surface of the sole 2 where the sole of the foot is located.

[0038] FIG6 shows a third embodiment of the integrated sole and blade support structure of the present invention. In ice hockey, since ice hockey players often exert force at the heel during play, the elastic member 4 in this embodiment can simply be a rear elastic piece 41 extending obliquely upward from the central top surface of the sole 2 to above the top surface of the sole 2 where the heel is located. Similarly, the angle between the bottom surface of the rear elastic piece 41 and the top surface of the sole 2 where the heel is located is acute. This allows the rear elastic piece 41 at the heel to be compressed and store energy when the ice hockey player pushes off the ice, providing a recoil force, enabling the player to quickly generate explosive power. Similarly, at this time, an extended rear support piece 43 can be provided at one end of the rear elastic piece 41 by bending downward or upward. The angle between the rear support piece 43 and the rear elastic piece 41 is an acute angle. When the rear support piece 43 is bent downward, the end of the rear support piece 43 abuts against the top surface of the heel of the sole 2. In this embodiment, the rear support piece 43 is in a semi-arc shape with both ends raised upward. When the rear elastic piece 41 and the rear support piece 43 are subjected to pressure, the rear support piece 43 can slide more smoothly along the top surface of the heel of the sole 2 to unload the force, and can provide stronger supporting force when rebounding.

[0039] For speed skaters, since the force point for starting to push off the ice is on the forefoot, as shown in Figure 7, this is a fourth embodiment of the integrated structure of the sole and the knife holder in the present invention. In this embodiment, the elastic member 4 may simply be a front elastic piece 42 extending obliquely upward from the central top surface of the sole 2 to the top surface of the sole 2 where the sole of the foot is located. Similarly, the angle between the front elastic piece 42 and the top surface of the sole 2 where the sole of the foot is located is acute. In order for speed skaters to obtain greater elastic recoil force when pushing off the ice, a front support piece 44 may also be provided which is bent downward or upward and extended from one end of the front elastic piece 42, and the angle between the front support piece 44 and the front elastic piece 42 is acute.

[0040] It should be noted that: please refer to Figure 8 which shows the fifth embodiment of the integrated structure of the sole and the knife holder in the present invention. In this embodiment, the elastic member 4 can also be based on the above embodiment and can also be provided with a front elastic piece 42 and a rear elastic piece 41 at the heel position and the sole position of the sole 2 at the same time, and also have a rear support piece 43 and a front support piece 44.

[0041] As shown in Figure 9, this is the sixth embodiment of the integrated structure of the sole and the knife holder in the present invention. In order to more accurately generate rebound and recoil forces at the force point of the foot, a rear separation groove 45 with an opening at one end can be provided in the center of the rear support piece 43, and a front separation groove 46 with an opening at one end can be provided in the center of the front support piece 44. When the heel exerts force during the ice-pushing process, since the foot is usually in an oblique pushing state, the force position of the sole of the foot will become unevenly distributed, and may be concentrated in the outer area of ​​the foot or in the inner area of ​​the foot. Therefore, the rear separation groove 45 and the front separation groove 46 can allow the buffering force and rebound force of the elastic member 4 to be distributed on the side that receives force, so that the wearer can receive more accurate rebound force. For example, when the force applied by the foot is at the big toe or medial cuneiform position, the front support plate 44 at the corresponding position on the side of the front separation groove 46 will be pressed down first. After the downward force disappears, the front support plate 44 at this part will first generate a recoil force due to its elasticity, pushing the sole of the foot at the big toe or medial cuneiform position upward, thereby allowing the athlete to generate a stronger feedback force when pushing off the ice based on his or her own explosive power.

[0042] As shown in Figures 1, 10 and 11, a pair of ice skates includes the above-mentioned sole and blade holder integrated structure, and a shoe body 5 is connected to the sole 2. Figure 1 shows an embodiment of the ice skates of the present invention. The shoe body 5 can also be made of carbon fiber material and connected to the sole 2 by glue or sewing to form a complete ice skate. The shoe body 5 can also be made by traditional processes such as injection molding. It should be noted that the shoe body 5 referred to here does not have a sole, that is, the bottom of the shoe body 5 is connected to the inside of the shoe. The shoe body 5 becomes a complete shoe body only after being connected to the sole 2. The sole 2 and the blade holder 1 are made into a complete whole using carbon fiber material. The purpose is to reduce the risk of cracking and separation caused by the traditional blade holder being screwed together with the sole, and to reduce subsequent processing procedures. The integrally formed sole 2 and blade rest 1 ensure the skates remain secure even after athletes perform intense movements such as jumping, preventing the blade rest from separating from the sole. Furthermore, the high hardness and excellent elasticity of the carbon fiber material itself can also assist athletes in unloading forces. In this embodiment, after the shoe body 5 is connected to the sole 2, the elastic member 4 made of carbon fiber can be selected based on the application scenario, such as a separate rear elastic sheet 41 or a separate front elastic sheet 42, or, as described in the first embodiment, the front elastic sheet 42 and the rear elastic sheet 41 can be made from a single piece of carbon fiber with the same contour as the sole 2. The aforementioned rear support sheet 43 and front support sheet 44 can be selectively added to the front elastic sheet 42 and the rear elastic sheet 41 to meet different needs. The elastic part 4 made of carbon fiber and the one-piece molded sole 2 and blade support 1 can effectively provide great explosive power to the foot through the recoil force at the moment when the athlete pushes off the ice, and will also cushion the vibration at the moment of taking off and landing, ensuring the safety and comfort of the wearer while providing an effect that is more in line with the biomechanics of human movement.

[0043] In addition, as shown in Figures 10 and 11, another embodiment of the ice skate shoes in the present invention is shown. It can be clearly seen from the figures that this embodiment is basically the same as the first embodiment, and only differs in the connection method between the shoe body 5 and the sole 2. The heel position and the sole position below the shoe body 5 are respectively provided with downwardly extending plug posts 51 and a plurality of screw holes 52 respectively arranged around the plug posts 51. Positioning holes 21 corresponding to the plug posts 51 and through holes 22 corresponding to the screw holes 52 are respectively penetrated on the sole 2. The plug posts 51 are inserted into the corresponding positioning holes 21, and screws and corresponding screw holes are penetrated in the through holes 22. The shoe body 5 is connected with the sole 2 by the screw holes 52. In this embodiment, the shoe body 5 itself has a sole surface 53 with a closed bottom to form a complete shoe body. The plug post 51 and each screw hole 52 are formed on the sole surface 53. After the shoe body 5 is aligned with the sole 2 and pressed, the plug post 51 is inserted into the corresponding positioning hole 21 for positioning. Then, the screw is inserted into the through hole 22 and screwed into the corresponding screw hole 52 to complete the connection and fixation between the shoe body 5 and the sole 2. It should be noted that the elastic part 4 is arranged in the shoe body 5. The elastic part 4 can be connected and fixed to the sole surface 53 by screws, or the elastic part 4 and the sole surface 53 can be made into one piece. Of course, the elastic member 4 can also be arranged between the sole surface 53 and the top surface of the sole 2 as shown in Figure 12. For example, in ice skates worn in short track speed skating, the front end of the shoe body 5 and the front end of the blade support are hinged together. At the moment of lifting the foot, the rear half of the ice skate and the shoe body can be separated, just like walking in slippers. In this embodiment, the shoe body 5 is directly hinged to the front end of the sole 2 through the sole surface 53 at its bottom as shown in Figure 12. In this case, the shoe body 5 can be more stable, and when the heel is stepped on, the rear elastic sheet 41 is installed alone or together with the rear support sheet 43 at the heel position, or the front elastic sheet 42 is installed alone or together with the front support sheet 44 at the sole position of the sole 2, so as to achieve the required rebound force to enhance the explosive power when pushing off the ice.
