Durable anti-deformation shaping composite sole

Abstract

The utility model relates to the technical field of soles, and provides a durable anti-deformation shaping composite sole, which is characterized in that shaping edges are convexly arranged on two opposite sides of a bottom surrounding edge, and the shaping edges on the two sides are used for shaping the two sides of the sole, so that the sole can be prevented from structural deformation towards the two sides. The reinforcing strips are arranged on the outer sides of the shaping edges at intervals, so that the structural strength of each shaping edge is relatively enhanced, and the shaping effect of the shoe sole is further improved. Meanwhile, the shaping piece and the gasket are sequentially attached to the inner side of the shoe sole body, so that the durability of the inner side of the shoe sole body is improved on the premise that wearing comfort is guaranteed, and structural stability is guaranteed. Due to the fact that the heat dissipation holes are formed in the shoe sole body in the penetrating mode, heat generated in the walking or running process can be dissipated outwards through the heat dissipation holes, the situation that the shoe sole is fatigued, soft and collapsed due to heating is avoided, and the deformation resistance and the shaping effect of the shoe sole are further improved.

Description

Technical Field

[0001] The utility model belongs to the technical field of soles, and particularly relates to a wear-resistant, deformation-resistant and shaped composite sole. Background Art

[0002] The soles are often made of rubber, PVC, EVA, TPR, PU and other materials. However, due to the relationship between the creep of the sole material itself and the temperature and stress, people often find that the soles have slight deformation and wear after wearing the shoes for a period of time, which not only affects people's aesthetics of the soles, but also greatly reduces the comfort and service life of the soles. After long-term wearing, the deformation of the soles will cause collapse, posing a safety hazard to people's walking health.

[0003] In the prior art CN221241828U, a "low-density high-property sole" is provided, which includes a low-density inner lining, a medium-density side circumference and a high-density bottom sole combination, and the combination of different densities is used to improve the stability of the sole when worn, and ensure the overall support and shaping effect of the sole. However, the prior art can reduce the wear of the sole contact surface and play a shaping role, but due to the increase in temperature and the stress on the sole caused by long-term wearing, the anti-deformation and shaping effects of the sole are not obvious. Utility Model Content

[0004] Based on the above background, the purpose of the utility model is to provide a wear-resistant, deformation-resistant and shaping composite sole to avoid the problem of sole collapse due to deformation and improve the deformation resistance and shaping effect of the sole.

[0005] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0006] A wear-resistant, deformation-resistant and shaped composite sole comprises: a sole body, comprising an inner side and a bottom side along the thickness direction, and the sole body is provided with heat dissipation holes penetrating the inner side and the bottom side; a bottom peripheral edge is arranged on the sole body and is arranged around the outer periphery of the inner side, and shaping edges are convexly provided on opposite sides of the bottom peripheral edge, and a side surface of each shaping edge facing away from the inner side is provided with parallel and spaced reinforcement strips; a shaping sheet is attached to the inner side and covers the heat dissipation holes; and a gasket is attached to the shaping sheet.

[0007] Furthermore, the inner side is concave to form a mounting groove, the shaping sheet is attached to the bottom wall of the mounting groove, and the heat dissipation hole is arranged on the bottom wall of the mounting groove.

[0008] Furthermore, a pressing edge is circumferentially provided on the edge of the slot opening of the installation slot, a clamping gap is formed between the pressing edge and the bottom wall of the installation slot, and an abutting edge is circumferentially provided on the shaping sheet, and the abutting edge is clamped in the clamping gap.

[0009] Further, positioning holes are provided through the abutting edge, and a positioning post is connected between the abutting edge and the bottom wall of the mounting groove, and the positioning post passes through the positioning holes.

[0010] Further, an elastomer is further included. A fixing hole is provided through the inner heel portion, and the elastomer is embedded in the fixing hole.

[0011] Further, a restraint band is further included. The restraint band is located inside the sole body, and two ends of the restraint band are respectively fixed to the two shaping edges correspondingly, and the gasket is press-connected to the restraint band.

[0012] Further, the restraint band includes a first connecting portion, a second connecting portion and an elastic portion connected between the first connecting portion and the second connecting portion. The first connecting portion and the second connecting portion are respectively fixed to the two shaping edges correspondingly, and the gasket is press-connected to the elastic portion.

[0013] Further, a plurality of anti-slip blocks are further included, and all the anti-slip blocks are arranged at intervals along the length direction of the sole body on the bottom side.

[0014] The utility model has the following beneficial effects:

[0015] (1) Shaping edges are convexly provided on opposite sides of the bottom perimeter edge. The shaping edges on both sides are used to shape the two sides of the sole, so as to avoid structural deformation of the sole to both sides. Since reinforcing strips are arranged at intervals on the outer side of the shaping edges, the structural strength of each shaping edge is relatively enhanced, which is beneficial to further improving the shaping effect of the sole. At the same time, a shaping sheet and a gasket are sequentially attached to the inner side of the sole body. On the premise of ensuring comfortable wearing, the wear resistance of the inner side of the sole body is improved, and the structural stability is ensured. Also, since heat dissipation holes are provided through the sole body, during walking or running, the generated heat can be dissipated outward through the heat dissipation holes, avoiding the sole from becoming soft and collapsing due to heat, and further improving the anti-deformation and shaping effects of the sole. In addition, the shaping sheet covers the heat dissipation holes, so that while ensuring heat dissipation, it can prevent stones or dust from entering the sole body through the heat dissipation holes and reducing the wearing comfort.

[0016] (2) An installation groove is concavely provided on the inner side. By using the installation groove, it is convenient to stably fix the shaping sheet on the sole body, avoiding the shaping sheet from loosening during walking or running and affecting the wearing comfort.

[0017] (3) A pressing edge is provided on the edge of the notch of the installation groove. A clamping gap is formed between the pressing edge and the bottom wall of the installation groove. Therefore, after the shaping sheet is installed in the installation groove, the abutting edge of the shaping sheet is stably clamped in the clamping gap, so that the shaping sheet is stably fixed in the installation groove, which is beneficial to improving the structural stability of the sole.

[0018] (4) A restraint strap is connected between the two shaped edges, and the gasket is crimped on the restraint strap. In this way, when the foot steps on the restraint strap, the tension of the restraint strap pulls the two shaped edges on both sides respectively, making it easier for the two shaped edges to approach each other, thus ensuring that the sole is not easily deformed and collapsed outward, and further ensuring the stable and reliable structure of the sole.

[0032] In one embodiment, please refer to Figures 1 to 6 The present application provides a wear-resistant, deformation-resistant and shaped composite sole 100, comprising: a sole body 10, which includes an inner side 11 and a bottom side 12 along the thickness direction, and the sole body 10 is provided with a heat dissipation hole 13 that penetrates the inner side 11 and the bottom side 12; a bottom peripheral edge 50, which is arranged on the sole body 10 and is arranged around the outer periphery of the inner side 11, and shaping edges 51 are convexly provided on opposite sides of the bottom peripheral edge 50, and a side surface of each shaping edge 51 facing away from the inner side 11 is provided with parallel and spaced reinforcement strips 52; a shaping sheet 30, which is attached to the inner side 11 and covers the heat dissipation hole 13; a gasket 40, and the gasket 40 is attached to the shaping sheet 30.

[0033] The above-mentioned durable and anti-deformation shaped composite sole 100 is convexly provided with shaping edges 51 on opposite sides of the bottom perimeter 50. The shaping edges 51 on both sides are used to shape both sides of the sole 100, thus avoiding structural deformation of the sole 100 to both sides. Since reinforcing strips 52 are spaced on the outer side of the shaping edges 51, the structural strength of each shaping edge 51 is relatively enhanced, which is beneficial to further improving the shaping effect of the sole 100. At the same time, a shaping sheet 30 and a gasket 40 are sequentially attached to the inner side 11 of the sole body 10. On the premise of ensuring comfortable wearing, the wear resistance of the inner side 11 of the sole body 10 is improved, and the structural stability is ensured. Also, since heat dissipation holes 13 are provided through the sole body 10, during walking or running, the generated heat can be dissipated outward through the heat dissipation holes 13, avoiding the sole 100 from becoming soft and collapsing due to heat, and further improving the anti-deformation and shaping effects of the sole 100. In addition, the shaping sheet 30 covers the heat dissipation holes 13, so that while ensuring heat dissipation, it can prevent stones or dust from entering the sole body 10 through the heat dissipation holes 13 and reducing the wearing comfort.

[0034] It should be explained that in order to improve the wear resistance of the sole body 10, a lightweight and super wear-resistant rubber material is used to enhance the anti-slip and wear resistance of the sole 100, and improve the overall service life and wear resistance of the sole 100. In the inner side 11 of the sole body 10, polyurethane or TPU materials with excellent resilience, wear resistance and fold resistance can also be used, and the lightweight and shock-absorbing effects are obvious.

[0035] The shaping sheet 30 is arranged on the inner side 11 of the sole body 10, which can prevent the whole sole 100 from being compressed inward. In this way, cooperating with the shaping edges 51 on both sides, effective anti-deformation and shaping effects can be achieved. At the same time, the shaping sheet 30 can also have effective wear resistance. It is made of carbon fiber, and the longitudinal stiffness of the carbon fiber is not less than 400 kN, and its toughness is excellent and it is not easy to break under pressure. The shaping sheet 30 is placed from the heel to the arch to the forefoot. According to the force-bearing structure design improvement of the three parts of the heel touching the ground, the whole foot supporting and the forefoot pushing away from the ground surface during human movement, the support and toughness of the outer sole waist part are improved. At the same time, it can slow down the force on the sole 100 during the human movement process, and evenly distribute the force to the heel, arch and forefoot parts of the shoe through the shaping sheet 30, which has a certain anti-deformation and shaping effect on the sole 100.

[0036] In addition, the gasket 40 is arranged on the shaping sheet 30, and materials with high wear resistance and high resilience can be used.

[0037] Furthermore, please refer to Figure 1 and Figure 2, an installation groove 14 is concavely formed on the inner side 11. The shaping piece 30 is attached to the bottom wall of the installation groove 14, and the heat dissipation holes 13 are arranged on the bottom wall of the installation groove 14. It can be seen that by concavely arranging the installation groove 14 on the inner side 11 and using the installation groove 14, it is convenient to stably fix the shaping piece 30 on the sole body 10, and prevent the shaping piece 30 from loosening during walking or running, which affects the wearing comfort.

[0038] It should be noted that the shape of the installation groove 14 can be designed according to the shape of the shaping piece 30, which is convenient for the shaping piece 30 to fit better in the installation groove 14 and improves the compactness of the structure.

[0039] Furthermore, please refer to Figure 4 and Figure 5 , a pressing edge 20 is circumferentially arranged on the edge of the notch of the installation groove 14. A clamping gap 21 is formed between the pressing edge 20 and the bottom wall of the installation groove 14. A butting edge 31 is circumferentially arranged on the shaping piece 30, and the butting edge 31 is clamped in the clamping gap 21. It can be seen that by arranging the pressing edge 20 on the edge of the notch of the installation groove 14 and forming the clamping gap 21 between the pressing edge 20 and the bottom wall of the installation groove 14. Therefore, after the shaping piece 30 is installed in the installation groove 14, the butting edge 31 of the shaping piece 30 is stably clamped in the clamping gap 21, so that the shaping piece 30 is stably fixed in the installation groove 14, which is beneficial to improving the structural stability of the sole 100.

[0040] In one embodiment, please refer to Figure 5 , a positioning hole 32 is penetrated through the butting edge 31. A positioning post 22 is connected between the butting edge 31 and the bottom wall of the installation groove 14, and the positioning post 22 is penetrated through the positioning hole 32. It can be seen that through the cooperation of the positioning hole 32 and the positioning post 22, the shaping piece 30 is more stably combined in the installation groove 14.

[0041] Specifically, both the positioning hole 32 and the positioning post 22 can be multiple, and they are arranged one-to-one. The multiple positioning holes 32 are arranged at intervals along the circumference of the shaping piece 30.

[0042] In one embodiment, please refer to Figure 2 , it further includes an elastomer 70. A fixing hole 16 is penetrated through the heel part of the inner side 11, and the elastomer 70 is embedded in the fixing hole 16. It can be seen that the rebound performance of the sole 100 is improved and the comfort is improved.

[0043] It should be noted that by using EVA (Ethylene VinylAcetate Copolymer, translated as ethylene-vinyl acetate copolymer) supercritical foaming material, it is light in weight, has rebound and buffering properties, can effectively absorb the ground reaction force, protect joints, and improve the comfort of the sole 100. The surface of the high-rebound block is designed with a grid pattern, which further enhances the shock-absorbing effect of the high-rebound block.

[0044] In one embodiment, it further includes a restraint strap 60. The restraint strap 60 is located inside the sole body 10, and both ends of the restraint strap 60 are respectively fixedly corresponding to two shaping edges 51. The gasket 40 is crimped on the restraint strap 60. It can be seen that the restraint strap 60 is connected between the two shaping edges 51, and the gasket 40 is crimped on the restraint strap 60. In this way, when the foot steps on the restraint strap 60, the tension force of the restraint strap 60 respectively pulls the two shaping edges 51 on both sides, making it easier for the two shaping edges 51 to approach each other, so as to ensure that the sole 100 is not prone to collapse deformation outward, and further ensure the structural stability and reliability of the sole 100.

[0045] Further, please refer to Figure 6 , the restraint strap 60 includes a first connecting portion 61, a second connecting portion 62 and an elastic portion 63 connected between the first connecting portion 61 and the second connecting portion 62. The first connecting portion 61 and the second connecting portion 62 are respectively fixedly corresponding to the two shaping edges 51, and the gasket 40 is crimped on the elastic portion 63.

[0046] It should be explained that both the first connecting portion 61 and the second connecting portion 62 can be made of fabric. At the same time, in order to avoid the friction of the first connecting portion 61 and the second connecting portion 62 against the foot, sponge or other flexible materials can be provided on the first connecting portion 61 and the second connecting portion 62.

[0047] In one embodiment, it further includes a plurality of anti-slip blocks 15, and all the anti-slip blocks 15 are arranged at intervals along the length direction of the sole body 10 on the bottom side 12.

[0048] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present invention should also fall within the protection scope of the present invention.
