Description

Technical Field

[0001] The utility model relates to the field of sole structures. Background Art

[0002] The most common shock-absorbing methods for sports shoe soles are to achieve the shock-absorbing effect through the performance of the sole material, the structural setting of the sole, or a combination of the two. Among them, the shock-absorbing effect achieved only by the performance of the sole material is limited in terms of consumers' perception of the shock-absorbing effect during use, and most of the time it is not particularly obvious. There are many publicly available technical solutions that rely only on the structural setting of the sole or the combination of the performance of the material, but there are generally problems such as impractical structural settings, unsatisfactory shock-absorbing effects of the structures, failure to meet the standards of some industry performance tests as soles, short service life, and even structural settings that cannot be manufactured into products that can be put on the market. Therefore, there are not many sole structural settings that achieve shock-absorbing effects adopted in the market, and some that achieve shock-absorbing effects through peculiar structural settings have not been popular for a long time.

[0003] On the other hand, the appearance design of the sole is novel and eye-catching, which is one of the main directions of current shoe product design and development, so as to meet market needs and increase market sales share. This is achieved more through structural settings. Therefore, new sole structures are still under development, especially shock-absorbing soles that are suitable for practical use and can be actually put into production and manufacturing, which need to be improved and developed. Utility Model Content

[0004] The purpose of the utility model is to provide a new structure, which can achieve better shock-absorbing effect and is more conducive to the actual production and manufacturing of a hollow dislocation shock-absorbing sole.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is: a hollow staggered shock-absorbing sole, which includes, from top to bottom, an upper midsole, a lower midsole and a wear-resistant bottom plate, which are bonded together. The lower midsole includes an upper plate and a lower plate, and the opposite surfaces of the upper plate and the lower plate are respectively provided with corresponding shock-absorbing bosses. The protruding outer ends of the shock-absorbing bosses at corresponding positions of the upper plate and the lower plate can be movably pressed together to support the lower midsole, and the space around each shock-absorbing boss of the upper plate and the lower plate is a hollow staggered shock-absorbing space. When the lower midsole is compressed in the up and down directions, the corresponding shock-absorbing bosses of the upper plate and the lower plate can be staggered toward the staggered shock-absorbing space.

[0006] The upper piece and the lower piece of the lower midsole are foamed separately, and the shock-absorbing bosses of the upper piece and the lower piece are arranged corresponding to the main stress-bearing parts of the human foot, and the shock-absorbing bosses are arranged at intervals in the areas corresponding to the stress-bearing parts. The shock-absorbing boss of the lower piece is a conical shock-absorbing boss, and the protruding outer end of the shock-absorbing boss of the upper piece is an inclined guide end, and the inclined guiding direction of the inclined guide end is set in a direction that can guide it toward the center direction of the area of ​​the stress-bearing part. The shock-absorbing boss in the area corresponding to the stress-bearing part of the lower piece on the wear-resistant bottom piece is convexly provided with a guide support column, and a support hole for the guide support column to be embedded correspondingly is provided at the center of the shock-absorbing boss on the lower surface of the lower piece.

[0007] The upper piece and / or the lower piece are provided with a foamed arch support block in the area corresponding to the arch position of the foot, a flat front end connection area in the area corresponding to the toe position of the foot and / or a heel connection section in the edge area corresponding to the heel position of the foot, and the upper piece and the lower piece are provided with connection positioning structures in the corresponding arch support block, the front end flat connection area and / or the heel connection section.

[0008] The protruding outer ends of the shock-absorbing bosses at corresponding positions of the upper piece and the lower piece are offset and correspondingly pressed together.

[0009] The shock-absorbing boss is a cone-shaped shock-absorbing boss and / or the protruding outer end of the shock-absorbing boss is an arc-shaped end or an inclined guide end.

[0010] The bottom surface of the lower midsole is in a shape with the front and rear ends tilted upward.

[0011] The outer periphery of the lower midsole is covered with a protective cover.

[0012] The protective cover is a transparent protective cover through which the structure between the upper sheet and the lower sheet can be seen.

[0013] The wear-resistant bottom sheet and / or the upper midsole are formed with a reinforced bonding wall wrapped around the periphery of the lower midsole.

[0014] By adopting the above technical solution, the beneficial effect of the utility model is as follows: the upper and lower pieces of the lower midsole of the sole of the above structure are supported by the relative shock-absorbing bosses, and the outer protruding ends of the upper and lower corresponding shock-absorbing bosses are not connected and the wrong shock-absorbing space is set, so that when the shock-absorbing boss is compressed, it can be biased to one side so that the upper piece can be deformed to receive the pressure to achieve shock absorption, and the reset elastic force of the upper piece and the biased reset elastic force of the shock-absorbing boss after the lower midsole is compressed and deformed can also play the role of elastic support to disperse the pressure and elastically support the sole, thereby achieving a better shock-absorbing effect, and the lower midsole can be quickly reset after losing pressure. The structure can be set on the sole in the whole palm or in part. At different positions of force, the elastic coefficient of the corresponding position can be changed by the thickness, protruding height, layout density, material selection, etc. of the shock-absorbing boss to achieve different shock-absorbing performance effects. In addition, the structural setting is more practical and simple, and is easy to manufacture and realize. The molding parts can be produced separately, and the core-pulling molding parts can be produced in one piece. The appearance effects of different structural settings can be achieved, thereby achieving the above-mentioned purpose of the utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0023] This embodiment discloses a hollow staggered shock-absorbing sole, such as Figure 1 , Figure 2 and Figure 3As shown, from top to bottom, it includes an upper midsole 1 whose upper surface is bonded to the upper, a lower midsole 2 bonded to the bottom surface of the upper midsole 1, and a wear-resistant bottom sheet 3 bonded to the bottom surface of the lower midsole 2 for non-slip contact with the ground. The improved structural arrangement of the utility model is described in detail below.

[0024] like Figure 1 As shown, the lower midsole 2 includes an upper piece 21 and a lower piece 22 corresponding to each other. Here, the lower midsole 2 can be a structural component of an integrally formed upper piece 21 and a lower piece 22 according to the specific structural setting, or it can be a separate component in which the upper piece 21 and the lower piece 22 are separately formed as in the following structure, which will be described in detail later. The shock-absorbing effect of the lower midsole 2 of the utility model is achieved by protruding and arranging corresponding shock-absorbing bosses 23 on the opposite surfaces of the upper piece 21 and the lower piece 22, and the space around each shock-absorbing boss 23 of the upper piece 21 and the lower piece 22 is a hollow staggered shock-absorbing space 24. The structural settings of the two embodiments are described below.

[0025] like Figure 1 As shown, the protruding outer ends of the shock absorbing bosses 23 at the corresponding positions of the upper piece 21 and the lower piece 22 can be movably pressed together to support the lower midsole 2. The pressing together here can be completely corresponding up and down or offset corresponding up and down but not connected, so that the lower midsole 2 can be movably supported. Figure 1 The protruding outer ends of the shock-absorbing bosses 23 shown in the figure are partially corresponding and partially non-corresponding offset corresponding structures. When the lower midsole 2 is subjected to pressure in the up-down direction, the shock-absorbing bosses 23 at the corresponding positions of the upper piece 21 and the lower piece 22 can be offset to the offset shock-absorbing space 24, thereby achieving the desired shock-absorbing effect. Here, in order to facilitate the realization of the compression bias, the shock-absorbing bosses 23 can be provided with cone-shaped shock-absorbing bosses 23, and the cone-shaped top surface can reduce the contact area of ​​the top and the inclined side wall can have a bias. In addition, the shape can also increase the connection end surface of the shock-absorbing boss 23 and the upper piece 21 or the lower piece 22. Increasing the connection surface of the shock-absorbing boss 23 can make the shock-absorbing boss 23 have better compressive support performance and better support effect for larger pressure. In addition, if the structure of the shock-absorbing boss 23 is completely corresponding to the upper and lower parts, in order to facilitate the shock-absorbing effect, the protruding outer end of the shock-absorbing boss 23 can be further set to a circular arc end or an inclined guide end, which can play a significant role in the guiding deviation.

[0026] The structure of the shock-absorbing boss 23 can also select different structural settings according to the pressure size of the setting position, the required shock-absorbing performance, etc., and the setting of this structure can be shown in the figure. The upper piece 21 and the lower piece 22 of the lower midsole 2 are foamed separately, and the shock-absorbing bosses 23 of the upper piece 21 and the lower piece 22 are arranged corresponding to the main force-bearing parts of the human foot. As shown in the figure, the shock-absorbing bosses 23 are arranged at intervals in the area corresponding to the force-bearing parts of the heel and the middle section of the forefoot, and the shock-absorbing bosses 23 of the lower piece 22 are cone-shaped shock-absorbing bosses 23, and the shock-absorbing bosses 23 of the upper piece 21 are The protruding outer end is an inclined guide end 231, and the inclined guide direction of the inclined guide end 231 is set to be able to guide towards the center direction of the region of the force-bearing part. Through the above-mentioned structural setting, the shock-absorbing boss 23 is arranged in a circle corresponding to the heel and the middle part of the forefoot of the human body, and the inclined guide end 231 is inclined toward the center direction of the circle, which can make the shock absorption of the heel have obvious elastic support effect. Because it is set in a circle, the elastic deformation in the circle can be restrained from each other, which can effectively support under pressure and quickly recover when the pressure is lost. In addition, the shock-absorbing boss 23 in the area of ​​the wear-resistant bottom plate 3 corresponding to the stress-bearing part of the lower plate 22 is provided with a guide support column 31, and the lower surface of the lower plate 22 is provided with a support hole 232 for the guide support column 31 to be embedded in the center of the shock-absorbing boss 23. The guide support column 31 is used to further improve the support stability of the shock-absorbing boss 23 of the lower plate 22, thereby making the support deformation performance of the shock-absorbing boss 23 of the lower plate 22 different from that of the shock-absorbing boss 23 of the upper plate 21. The effect brought about by the difference is conducive to better realization of the above-mentioned structural effect.

[0027] In the above structure, in order to facilitate the structural molding and production of the upper piece 21 and the lower piece 22, a separate manufacturing method is adopted, and then the lower midsole 2 is formed by combining and connecting. In order to make the sole have better sole integrity and stability of the structural connection, a local positionable connection is also formed on the upper piece 21 and the lower piece 22. As shown in the figure, the upper piece 21 and / or the lower piece 22 are formed with a foamed arch support block 25 in the area corresponding to the arch position of the foot. The force at this position is relatively small and better support for the arch is required. The setting of the arch support block 25 can better support the arch and can also be used for connection over a larger area. The upper piece 21 and the lower piece 22 are connected to achieve a better connection effect. In addition, the upper piece 21 and / or the lower piece 22 has a flat front connecting area 26 in the area corresponding to the toe position of the foot, which serves as a stable connection at the front end. The upper piece 21 and / or the lower piece 22 has a heel connecting section 27 in the edge area corresponding to the heel position of the foot, which serves as a connection at the rear end. Such multiple connections have both connecting and positioning functions. To facilitate the connection positioning, the upper piece 21 and the lower piece 22 are provided with connection positioning structures such as limited edges, concave and convex positioning points, etc. at the corresponding arch support block 25, the front connecting area 26 and the heel connecting section 27.

[0028] In addition to the structural arrangement of the above specific embodiment, the structural arrangement of the utility model can also be arranged on the upper piece 21 and the lower piece 22 in a large area, and the upper and lower corresponding shock absorbing bosses 23 are as follows: Figure 3 The slightly misaligned corresponding parts are pushed together, and the protruding outer end of the shock-absorbing boss 23 is an arc-shaped protruding outer end that is conducive to the misalignment. The structure is simpler, and a mold structure can be designed to realize the integrated manufacturing of the lower midsole 2. This structural setting can also achieve a shock-absorbing effect, and the sole as a whole can be relatively flat and thin. In addition, the lower midsole 2 of this structure can be formed as shown in the figure, and its bottom surface is a shape structure with the front and rear ends tilted upward. The wear-resistant bottom sheet 3 is correspondingly attached to the bottom surface of the lower midsole 2. The shape structure with the front and rear ends tilted upward can realize the deformation shock absorption of the sole, thereby further improving the overall shock absorption performance.

[0029] Considering the application of different types of shoes, different environments, and different designs, the above various structural settings can further cover the periphery of the lower midsole 2 with a protective cover. The protective cover 2 can be a transparent protective cover that can see through the structure between the upper piece 21 and the lower piece 22. It can be partially transparent or fully transparent, which can increase the effect of the appearance design. Of course, it can also be opaque. In addition, in order to improve the structural strength of the bonding between the upper and lower parts of the sole, the wear-resistant bottom sheet 3 and / or the upper midsole 1 can also be further formed with a reinforced bonding wall covering the periphery of the lower midsole 2, which can make the overall structure of the sole more stable.

[0030] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
