Description

Technical Field

[0001] This utility model relates to the field of footwear technology, specifically to a shoe sole with a support structure. Background Technology

[0002] Existing shoe soles, especially those for athletic shoes, generally consist of a midsole and an outsole. The midsole typically uses a relatively soft material (such as EVA) to provide cushioning.

[0003] When the foot typically lands, the heel of the shoe strikes the ground first, then transitions forward to the forefoot. The heel bears most of the pressure when it strikes first. If the midsole is too soft, the heel of the shoe will deform excessively, easily causing collapse and deformation, resulting in relatively poor support. At the same time, the midsole's rebound performance is relatively poor, and it cannot provide sufficient propulsion during the transition from the arch of the foot to the forefoot, resulting in relatively low energy return efficiency.

[0004] In view of this, the applicant has conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

[0005] The purpose of this invention is to provide a shoe sole with a support structure that has relatively good support performance and relatively high energy return efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A shoe sole with a support structure includes an outsole and a midsole bonded to the outsole. The midsole is designated as a forefoot portion corresponding to the forefoot, an arch portion corresponding to the arch of the foot, and a heel portion corresponding to the heel. A groove is formed on the side of the midsole, and the support structure is fixedly embedded in the groove. The support structure includes a support piece, the hardness of which is greater than that of the midsole. The support piece includes an integrally connected support section and a rebound section. The support section is located on the rear side of the heel portion, with one end extending to the inner side of the heel portion and the other end extending to the outer side of the heel portion. The rebound section is integrally connected to the outer side of the support section at the heel portion, and the end of the rebound section away from the support section extends to the forefoot portion. A first through hole and a second through hole are formed on the rebound section, arranged along the front-rear direction of the midsole.

[0008] As an improvement of this utility model, the second through hole is closer to the support section than the first through hole. Both the first through hole and the second through hole are obtuse-angled triangular through holes. Each of the obtuse-angled triangular through holes faces downward at its obtuse angle. In the same obtuse-angled triangular through hole, the acute angle of one of the obtuse-angled triangular through holes that is closer to the support section is the first acute angle, and the corresponding other acute angle is the second acute angle. The first acute angle is greater than the second acute angle.

[0009] As an improvement of this utility model, the cross-sectional area of ​​the first through hole is smaller than the cross-sectional area of ​​the second through hole.

[0010] As an improvement of this utility model, the position of the obtuse angle of the obtuse triangle in the vertical section of the first through hole corresponds to the connection position between the forefoot and the arch, and the position of the obtuse angle of the obtuse triangle in the vertical section of the second through hole corresponds to the connection position between the arch and the heel.

[0011] As an improvement of this utility model, the rear end of the outsole is provided with a first bifurcated opening groove, the first bifurcated opening groove penetrates the outsole and extends to the arch of the foot, and the bottom of the midsole is provided with a first groove corresponding to the first bifurcated opening groove.

[0012] As an improvement of this utility model, the bottom of the shoe outsole is provided with a first anti-slip zone, which is located at the position of the shoe outsole corresponding to the middle of the forefoot. The first anti-slip zone is provided with a plurality of first anti-slip blocks, and each first anti-slip block is evenly distributed on the first anti-slip zone.

[0013] As an improvement of this utility model, the bottom of the shoe outsole has a second anti-slip zone formed at the corresponding positions on both sides of the first bifurcated opening groove. Each second anti-slip zone is provided with a plurality of second anti-slip blocks, and the second anti-slip blocks located in the same second anti-slip zone are evenly distributed.

[0014] As an improvement of this utility model, the outer side of the shoe midsole is integrally connected with a first buffer block inserted into the first through hole and a second buffer block inserted into the second through hole.

[0015] As an improvement of this utility model, the support sheet is a TPU sheet.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] By incorporating a support section, the midsole provides enhanced support, preventing excessive deformation when the heel strikes first, resulting in relatively good support performance. During the transition from heel strike to forefoot strike, pressure is applied to the rebound section, and during forefoot liftoff, the rebound section provides a certain propulsive force, assisting forefoot liftoff and resulting in relatively high energy return efficiency.

[0029] The utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] The terms "first," "second," etc., used in the specification, claims, and drawings of this utility model are used to distinguish different objects, rather than to describe a specific order.

[0031] like Figures 1-2 As shown, this embodiment provides a shoe sole with a support structure, including a shoe outsole 10 and a shoe midsole 20 composited on the shoe outsole 10. The shoe midsole 20 is the forefoot part corresponding to the position of the forefoot of the human foot, the shoe midsole 20 is the arch part corresponding to the position of the arch of the human foot, and the shoe midsole 20 is the heel part corresponding to the position of the heel of the human foot.

[0032] For ease of description, the vertical and horizontal directions of the sole are described as if the sole were placed normally on a horizontal surface. The side of the soles of the two shoes in the same pair facing each other is the inner side of the shoe, and the opposite side is the outer side of the shoe. The side facing the toe is the front side, and the opposite side is the back side.

[0033] The side of the midsole 20 has an inlay groove 21, and a support structure is fixedly embedded in the inlay groove 21. The support structure includes a support piece 22, and the hardness of the support piece 22 is greater than that of the midsole 20. In this embodiment, the support piece 22 is a TPU piece. The support piece 22 includes a support section 23 and a rebound section 24 integrally connected to each other. The support section 23 is located at the rear side of the heel, with one end extending to the inner side of the heel and the other end extending to the outer side of the heel. The rebound section 24 is integrally connected to the outer side of the support section 23 at the heel, and the end of the rebound section 24 away from the support section 23 extends to the forefoot. It should be noted that the support section 23 and the rebound section 24 are... The entire structure is seamless, with no obvious divisions and smooth transitions between sections. The support piece 22 is divided into two sections for ease of explanation. The rebound section 24 has a first through hole 25 and a second through hole 26 arranged along the front-rear direction of the midsole 20. The first through hole 25 and the second through hole 26 provide deformation space for the support piece 22. With the support section 23, the midsole is reinforced to prevent excessive deformation when the heel strikes the ground first, resulting in relatively good support performance. During the transition from heel strike to forefoot strike, pressure is applied to the rebound section 24. During the forefoot lift-off process, the rebound section 24 provides a certain propulsive force, assisting the forefoot to lift off the ground, resulting in relatively high energy return efficiency.

[0034] The second through hole 26 is closer to the support section 23 than the first through hole 25. Both the first through hole 25 and the second through hole 26 are obtuse triangular through holes. Each obtuse triangular through hole faces downward at its obtuse angle. In the same obtuse triangular through hole, the acute angle of one of the obtuse triangular through holes that is closer to the support section 23 is the first acute angle, and the corresponding other acute angle is the second acute angle. The first acute angle is greater than the second acute angle. Setting the first through hole 25 and the second through hole 26 as obtuse triangular through holes improves the pressure resistance and deformation resistance of the support piece 22.

[0035] The cross-sectional area of ​​the first through hole 25 is smaller than that of the second through hole 26. The position of the second through hole 26 is closer to the heel than the first through hole 25, effectively sharing the pressure when the heel hits the ground first.

[0036] The position of the obtuse angle of the first through hole 25 in the obtuse triangle of its vertical section corresponds to the connection position between the forefoot and the arch of the foot, and the position of the obtuse angle of the second through hole 26 in the obtuse triangle of its vertical section corresponds to the connection position between the arch of the foot and the heel.

[0037] The outsole 10 has a first bifurcated opening groove 27 at its rear end, which extends through the outsole 10 and reaches the arch of the foot. The first bifurcated opening groove 27 helps to reduce the weight of the outsole 10. The bottom of the midsole 20 has a first groove 28 corresponding to the first bifurcated opening groove 27. The first groove 28 helps to reduce the weight of the midsole 20.

[0038] The bottom of the outsole 10 is provided with a first anti-slip zone 29, which is located at the position corresponding to the middle of the forefoot of the outsole 10. The first anti-slip zone 29 is provided with a plurality of first anti-slip blocks 30, which are evenly distributed on the first anti-slip zone 29, which helps to improve the anti-slip effect of the outsole 10.

[0039] The bottom of the outsole 10 has a second anti-slip zone 31 formed at the corresponding positions on both sides of the first bifurcation opening groove 27. Each second anti-slip zone 31 is provided with multiple second anti-slip blocks 32. The second anti-slip blocks 32 in the same second anti-slip zone 31 are evenly distributed, which helps to further improve the anti-slip effect of the outsole 10.

[0040] The outer side of the shoe midsole 20 is integrally connected with a first buffer block 33 inserted in the first through hole 25 and a second buffer block 34 inserted in the second through hole 26. By setting the first buffer block 33 and the second buffer block 34, the support piece 22 is better fixed in the embedded groove 21, and the fixing effect is relatively good.

[0041] The present invention has been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the prior art, and these modifications all fall within the protection scope of the present invention.
