Description

Sole and blade support integrated structure and skates

Technical Field

The invention relates to the field of skates accessories, in particular to a sole and blade support integrated structure and skates.

Background

At present, skates used worldwide are mainly divided into an integral structure and a split structure. The integrated skates are heavy and cannot meet the technical requirements of the pattern skates, and the market competitiveness of the integrated skates is lost. The blade holder of the split type skates is usually connected by arc welding, brazing, fastening pieces or profiled bars, but has the problems of potential safety hazard and high manufacturing cost. At present, strict safety technical requirements are put forward for the water jet knife with an all-metal structure, but only a few processes can meet the requirements, and the water jet knife with the all-metal structure is high in production cost and low in yield. The split type skates are manufactured into the cutter holder in an arc welding, brazing or profiled bar connecting mode, the cutter holder is mounted on the sole through fasteners such as screws, the traditional manufacturing mode has the problem of different degrees, and particularly, when welding, the welding performance of two steel materials with different properties is poor, and the required rigidity degree cannot be achieved. Most importantly, due to vibration of the athlete in severe actions such as sliding, jumping and rotating, the cutter holder is connected with the sole through fasteners such as screws, the strength of the components is easy to be reduced, screw loosening or matching piece deformation loosening is easy to occur, after the athlete uses for a period of time, materials of the screws and connecting parts are easy to be tired, the strength of the connecting parts is reduced, and accordingly the cutter holder is loosened or the cutting edge falls off, so that the safety of the athlete is seriously affected.

Chinese patent publication No.: CN105214297B discloses a composite skates support. The composite skates support comprises a support body, wherein the support body comprises a shoe rack and a knife rest, the shoe rack comprises a toe support seat, a heel support seat and a connecting strip for connecting the toe support seat and the heel support seat, the shoe rack is made of carbon fiber, the knife rest is made of plastic, the knife rest is fixedly connected with the shoe rack in a pouring mode, the section of the connecting strip is in a concave shape, the bottom surface of the shoe rack is provided with a containing groove, a plurality of connecting holes are formed in the bottom of the containing groove at intervals, a pressing plate is filled in the containing groove, and the pressing plate and the knife rest are integrally formed. The invention relates to a shoe rack made of carbon fiber and a knife rest made of plastic, which are connected and formed by pouring, and can solve the problem that a water knife with an all-metal structure is manufactured by adopting complex processes such as arc welding, brazing and the like, but the thermal expansion coefficients of the plastic and the carbon fiber are different, when the temperature of the two materials is changed, the expansion coefficients of the two materials are also different, the physical properties are changed, the connection part is easy to deform or stress concentrate, and the connection part is easy to separate or break, so that the risk of easy splitting and separation between the shoe rack and the knife rest which form the knife rest is greatly increased particularly after intense movement.

In addition, because the sport related to the skates requires extremely large explosive force at the moment when the athlete steps off the ice, and also generates extremely large vibration force at the moment when the skates jump to the ground, in order to accord with the biomechanical characteristics of human sports, the invention claims that the technical scheme recorded by the invention can achieve the effects of increasing the buffering and energy storage of the shoe rack at the moment when the skates slide out and improving the speed sliding performance of the skates, and the effects are all from the elastic deformation generated after the shoe rack is stressed. Such deformation also makes it easy for shearing or torsion forces to be generated between the shoe rack and the blade carrier during movement, resulting in separation or breakage of the connection. In addition, the recoil force and the buffering capacity provided by the deformation generated by the shoe rack are very weak in practice, the moment of ice pedaling cannot be truly realized, and the recoil force provides the clamping to the explosive force of the athlete, so that the skates are not optimistic in speed sliding performance, and the skates are flat in damping effect.

The invention is further described in the following description and detailed description with reference to the drawings: the integrated structure of sole and blade holder as shown in fig. 1 to 10 comprises an integrated blade holder 1 and a sole 2, wherein a blade groove 11 capable of being inserted into an ice blade body 3 is formed in the bottom of the blade holder 1, and the sole position of the blade holder 1 at the connecting position with the sole 2 are hollow, so that certain elasticity can be provided for the sole 2. The sole 2 is provided with the elastic piece 4 which can buffer soles and/or heels, the elastic piece 4 and the integrally formed blade support 1 and the sole 2 are made of carbon fiber materials, the problem that the safety of the athlete is seriously affected due to the fact that the contact area between the blade support and the sole of a traditional skater is small can be effectively solved, due to the fact that the athlete shakes in severe actions such as sliding and jumping rotation, the blade support and the sole are connected through fasteners such as screws and the like, the strength of a component is easy to be reduced, screw loosening or matching piece deformation loosening is easy to occur, after a period of use, the materials of the screw and the connecting part are easy to fatigue, the strength of the connecting part is reduced, accordingly the blade support is loosened or the blade falls off, the problem that the safety of the athlete is seriously affected is solved, the high hardness and high elasticity of the carbon fiber materials enable the integrally formed sole 2 and the blade support 1 to be firmer, a certain buffering capacity is achieved, and the elastic piece 4 is matched, a larger bursting force can be provided at the moment that the athlete kicks ice, and the shaking force is buffered at the moment, and the landing moment is also in accordance with the biological characteristics of human body movement.

In the first embodiment of the sole and blade support integrated structure according to the present invention, as shown in fig. 2 to 3, after the skater rotates and jumps, the force-bearing point of the foot is involved in both the sole and heel positions, so that when the skater is used for the skater, the elastic member 4 may 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 of the heel position of the sole 2 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 of the sole 2, wherein the angle between the bottom surface of the rear elastic piece 41 and the top surface of the heel position of the sole 2 is acute, and the angle between the bottom surface of the front elastic piece 42 and the top surface of the sole 2 is acute, and the elastic member 4 and the sole 2 are integrally formed of carbon fiber material. After the foot applies pressure to the rear elastic piece 41 or the front elastic piece 42, the rear elastic piece 41 or the front elastic piece 42 can be sunk, and the high elasticity of the carbon fiber material is utilized to rebound and give effective support and resilience to the foot. Of course, in this embodiment, the elastic member 4 may be made of a carbon fiber sheet having the same shape as the outline of the sole 2 and integrally formed with the sole 2 separately from the sole 2, as shown in fig. 1. When the elastic member 4 is separate from the sole 2, as shown in fig. 1, the elastic member 4 and the sole 2 may be connected together by a screw 6, specifically, a counter bore 61 is penetrated in the center of the elastic member 4, a boss 23 is disposed in the center of the sole 2, the boss 23 is inserted into the counter bore 61, a connecting hole 24 with internal threads is disposed in the center of the boss 23, and the tapping end of the screw 6 is inserted from top to bottom and screwed into the connecting hole 24. The elastic element 4 and the sole 2 may be connected directly to the top surface of the sole 2, so that the elastic element 4 does not displace during intense movement. The front elastic piece 42 and the rear elastic piece 41 corresponding to the front sole and the rear heel position can effectively buffer vibration at the moment that the figure skater falls down after jumping.

In addition, in order to cope with the heavier person and increase the stronger elastic cushioning performance, as shown in fig. 4 and 5, in the second embodiment of the integrated structure of sole and blade support of the present invention, on the basis that the front elastic piece 42 extends obliquely upward from the center of the top surface of the sole 2 to above the top surface where the sole 2 is located, one end of the front elastic piece 42 is bent upward to form a front supporting piece 44, and the included angle between the front supporting piece 44 and the front elastic piece 42 is an acute angle, so that the bent front supporting piece 44 and the front elastic piece 42 can form a larger elastic cushioning capability under the requirement of heavier weight or stronger cushioning force. Of course, the front supporting piece 44 may also be bent downwards, and when the front supporting piece 44 is bent downwards, the tail end of the front supporting piece 44 abuts against the top surface of the sole 2 where the sole is located.

Fig. 6 shows a third embodiment of the integrated sole and blade holder structure of the present invention, wherein the hockey player's force application position during play is mostly focused on the heel position for hockey sports. Therefore, in this embodiment, the elastic member 4 may just be a rear elastic piece 41 extending obliquely upward from the central top surface of the sole 2 to above the top surface where the heel position of the sole 2 is located, and the included angle between the bottom surface of the rear elastic piece 41 and the top surface where the heel position of the sole 2 is located is also acute, so that when the skater pushes the ice surface with force, the rear elastic piece 41 at the heel can be compressed to store energy and provide a recoil force, so that the skater can quickly generate a bursting force. Also, at this time, an extended rear supporting piece 43 may be bent downward or upward at one end of the rear elastic piece 41, an acute angle is formed between the rear supporting piece 43 and the rear elastic piece 41, when the rear supporting piece 43 is bent downward, the end of the rear supporting piece 43 abuts against the top surface where the heel position of the sole 2 is located, in this embodiment, the rear supporting piece 43 is in a semi-arc shape with two ends tilted upward, when the rear elastic piece 41 and the rear supporting piece 43 are under pressure, the rear supporting piece 43 can slide smoothly along the top surface of the heel of the sole 2 to release force, and can provide stronger supporting force when rebounding.

In the case of a skater, since the force point for starting to kick ice is the front sole, as shown in fig. 7, in the fourth embodiment of the integrated structure of the sole and the blade holder of the present invention, the elastic member 4 may just be the front elastic piece 42 extending obliquely upward from the central top surface of the sole 2 to above the top surface of the sole 2, and the angle between the front elastic piece 42 and the top surface of the sole 2 is also acute, and in order to obtain a larger elastic recoil force when the skater kicks ice, the front supporting piece 44 may also be provided by bending downward or upward from one end of the front elastic piece 42, and the angle between the front supporting piece 44 and the front elastic piece 42 is also acute.

It should be noted that: referring to fig. 8, a fifth embodiment of the integrated sole and blade holder structure of the present invention is shown, in which the elastic member 4 may be a front elastic piece 42 and a rear elastic piece 41 provided at the heel position and the sole position of the sole 2, and have a rear supporting piece 43 and a front supporting piece 44.

In order to generate rebound and recoil force at the force point of the foot more precisely, a rear separation groove 45 with an opening at one end may be provided at the center of the rear support piece 43, and a front separation groove 46 with an opening at one end may be provided at the center of the front support piece 44, so that the force applied to the bottom of the foot may be unevenly distributed due to the fact that the foot is normally inclined to push the heel during ice making, and the force applied to the outer side of the foot may be concentrated at the inner side of the foot, and thus, the rear separation groove 45 and the front separation groove 46 may distribute the buffering force and rebound force of the elastic member 4 at the force receiving side, so that the wearer may receive more precise rebound force. For example, when the force application point of the foot is at the thumb or inner wedge position of the foot, the front supporting piece 44 at the corresponding position on one side of the front separating groove 46 is firstly pressed down, after the pressing force is lost, the front supporting piece 44 at the part firstly generates recoil force due to elasticity, and the sole of the thumb or inner wedge position of the foot is pushed upwards, so that the athlete generates stronger ice-kicking feedback force on the explosive force of the athlete.

In which an embodiment of the skates according to the present invention is shown in fig. 1, the shoe body 5 may be made of carbon fiber material and connected to the sole 2 by means of glue or stitching to form a complete skates, and the shoe body 5 may be injection-molded as in the conventional art. It should be noted that, the sole 5 is not provided with a sole, that is, the bottom of the sole 5 is connected with the inside of the shoe, the sole 5 is to be connected with the sole 2 to form a complete shoe body, and the sole 2 and the blade holder 1 are made into a complete whole by using carbon fiber materials, so as to reduce the risk of easy cracking and separation caused by screwing the conventional blade holder and the sole together, and reduce the subsequent processing procedures. The integrally formed sole 2 and the blade holder 1 can still ensure the firmness of the skates after the athlete makes violent actions such as jumping, the problem of separation of the blade holder and the sole can not occur, and the high hardness and excellent elasticity of the carbon fiber material can also assist the athlete in unloading force. After the shoe body 5 is connected with the sole 2 in this embodiment, the carbon fiber made elastic member 4 can be selected as a separate rear elastic member 41 or a separate front elastic member 42 according to the application, or the front elastic member 42 and the rear elastic member 41 are made of a single carbon fiber sheet having the same contour shape as the sole 2 as described in the first embodiment. And the aforementioned rear support piece 43 and front support piece 44 are selectively added to the front elastic piece 42 and rear elastic piece 41 to suit different needs. The elastic piece 4 made of carbon fibers and the integrated formed sole 2 and the cutter holder 1 can effectively provide a great explosive force for feet through recoil force at the moment of ice pedaling of athletes, and can buffer vibration at the moment of landing, so that the effect more conforming to the biomechanics of human body movement is provided on the basis of guaranteeing the safety and comfort of wearers.

In addition, as shown in fig. 10 and 11, another embodiment of the skates according to the present invention is different from the first embodiment in that, in the connection manner between the shoe body 5 and the sole 2, only the heel position and the sole position under the shoe body 5 are respectively provided with a downward extending post 51 and a plurality of screw holes 52 respectively provided around the post 51, the sole 2 is respectively penetrated with a positioning hole 21 corresponding to the post 51 and a through hole 22 corresponding to the screw hole 52, the post 51 is inserted into the corresponding positioning hole 21, a screw is inserted into the through hole 22 to be connected with the corresponding screw hole 52, in this embodiment, the shoe body 5 itself has a closed bottom sole 53 to form a complete shoe body, the post 51 and each screw hole 52 are formed on the sole 53, after the shoe body 5 is aligned with the sole 2, the post 51 is inserted into the corresponding positioning hole 21, and then the screw is screwed into the sole 4, and the elastic member 4 is formed by the elastic member 4, and the elastic member is connected with the sole 4 by screwing the screw hole 52 into the sole body 4. It is of course also possible to arrange the elastic element 4 between the tread 53 and the top surface of the sole 2, as shown in fig. 12, for example: in the skates worn in the shorthand skates, the front end of the skates body 5 is hinged with the front end of the skates support, the rear half of the skates and the skates body can be separated at the moment of lifting feet, just like a slipper is worn to walk, in this embodiment, the skates body 5 is directly hinged with the front end of the sole 2 through the sole surface 53 at the bottom of the skates body 5 as shown in fig. 12, thus the skates body 5 can be more stable, and the rear elastic piece 41 is independently or simultaneously installed with the rear supporting piece 43 at the heel position when the heel is stepped on, or the front elastic piece 42 is independently or simultaneously installed with the front supporting piece 44 at the sole position of the sole 2, so that the required anti-elastic force can be realized to enhance the explosive force during the ice-pushing.
