Description

Technical Field

[0001] The utility model relates to a sole and a shoe, in particular to a double-density sole and a running shoe with the sole. Background Art

[0002] The Chinese utility model patent with authorization announcement number CN202504361U discloses a sole that can improve comfort. The midsole of the sole is a double-layer structure with different densities, the upper layer is a soft layer, and the lower layer is a wear-resistant layer. In essence, it is a dual-density sole. This type of dual-density sole has both comfort and wear resistance. By changing the hardness of the lower layer, it can also have both comfort and support characteristics. It has been used in many shoes.

[0003] However, the existing dual-density soles have relatively low shock-absorbing stability due to the use of low-density flexible materials on the upper layer, making them difficult to be used in running shoes.

[0004] In view of this, the applicant conducted in-depth research on the structure of dual-density soles, which led to the present case. Utility Model Content

[0005] The utility model aims to provide a double-density sole with relatively high shock-absorbing stability and a running shoe with the sole.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A dual-density sole comprises a soft midsole and a hard midsole located below the soft midsole, an elastic plate is sandwiched between the soft midsole and the hard midsole, the outer side of the elastic plate passes through between the soft midsole and the hard midsole, and an elastic strip is embedded on the outer side of the soft midsole.

[0008] As an improvement of the utility model, the inner side and the rear side of the elastic plate are both passed through between the soft midsole and the hard midsole.

[0009] As an improvement of the utility model, a plurality of combination holes are provided on the elastic plate, and the combination holes include at least two circular holes arranged in a straight line and a strip hole for connecting two adjacent circular holes to each other. In the same combination hole, the diameter of the circular hole is larger than the width of the cross section of the strip hole, and the density of the combination holes arranged in the forefoot and heel parts of the elastic plate is greater than the density of the combination holes arranged in the arch part of the elastic plate.

[0010] As an improvement of the utility model, a plurality of circular through holes are also provided on the elastic plate.

[0011] As an improvement of the utility model, the elastic plate is provided with a plurality of elongated holes near its periphery, and each of the combined holes and each of the circular through holes are located in a space surrounded by the plurality of elongated holes.

[0012] As an improvement of the present invention, in the combination holes located at the forefoot and arch parts of the elastic plate, the arrangement direction of each circular hole is gradually inclined toward the outer side of the shoe from front to back, and in the combination holes located at the heel part of the elastic plate, the arrangement direction of each circular hole is gradually inclined toward the inner side of the shoe from front to back.

[0013] As an improvement of the present invention, the arch portion of the elastic plate is arranged to be gradually inclined downward from the inner side of the shoe to the outer side of the shoe.

[0014] As an improvement of the utility model, the outer side of the shoe of the elastic plate is arranged in a first wave shape at the arch and heel positions, and the elastic strip is arranged in a second wave shape at the position corresponding to the arch and heel of the elastic plate.

[0015] As an improvement of the utility model, the elastic plate is a TPU plate, and the elastic strip is a TPU strip.

[0016] A running shoe comprises the above-mentioned dual-density sole.

[0017] By adopting the above scheme, the utility model has the following beneficial effects:

[0018] 1. By clamping an elastic plate between the soft midsole and the hard midsole, and using the elastic plate as a force transmission medium between the soft midsole and the hard midsole, the stability of the force transmission is relatively good. At the same time, in conjunction with the elastic strips set on the soft midsole, the shock absorption stability of the sole can be greatly improved, especially the shock absorption stability after landing during running.

[0019] 2. By setting combined holes on the elastic plate, it helps to disperse the pressure on the sole of the foot and improve wearing comfort.

[0020] 3. Since the arch part of the elastic plate is gradually tilted downward from the inside of the shoe to the outside of the shoe, it helps to improve the inner arch support of the sole and the stability of the outer arch landing. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] like Figure 1-Figure 4 As shown, this embodiment provides a running shoe, including a dual-density sole, which can also be used for other shoes or sold independently. Therefore, this embodiment essentially also provides a dual-density sole.

[0033] It should be noted that shoes are usually used in pairs, so the same pair of shoes usually has two dual-density soles, and the structures of the two dual-density soles are the same. The following description takes one of the dual-density shoes as an example, and in this embodiment, the side of the two dual-density soles of the same pair of shoes facing each other is the inner side of the shoe, the side opposite to each other is the outer side of the shoe, the side facing the toe is the front side, and the other corresponding side is the back side. The position corresponding to the forefoot of a person's foot when in use is the forefoot portion of each component, the position corresponding to the arch of a person's foot when in use is the arch portion of each component, and the position corresponding to the heel of a person's foot when in use is the heel portion of each component.

[0034] The dual-density sole in this embodiment includes a soft midsole 10 and a hard midsole 20 located below the soft midsole 10, wherein soft and hard refer to the relative softness and hardness of the two midsoles, rather than the specific softness and hardness, that is, the soft midsole 10 is softer than the hard midsole 20, but the hard midsole 20 can also have a certain degree of softness. The specific materials of the soft midsole 10 and the hard midsole 20 can be set according to actual needs, such as using EVA materials, etc., which will not be described in detail here.

[0035] An elastic plate 30 is sandwiched between the soft midsole 10 and the hard midsole 20. The elastic plate 30 is preferably a TPU plate or a carbon plate. The outer side of the elastic plate 30 passes through between the soft midsole 10 and the hard midsole 20, that is, the outer side of the elastic plate 30 is exposed to the outside, completely separating the outer sides of the soft midsole 10 and the hard midsole 20 to provide better support. Preferably, in this embodiment, the inner side and the rear side of the elastic plate 30 pass through between the soft midsole 10 and the hard midsole 20, which can further improve the support performance and is more beautiful.

[0036] The elastic plate 30 is provided with a plurality of combination holes 31, which include at least two circular holes 32 arranged in a straight line and a strip hole 33 for interconnecting two adjacent circular holes 32. The interconnected strip holes 33 and circular holes 32 have an arc transition. In the same combination hole 31, the diameter of the circular hole 32 is greater than the width of the cross section of the strip hole 33, and the spacing between two adjacent circular holes 32 can be arranged according to actual needs. The number of circular holes 32 and the spacing between the circular holes 32 of different combination holes 31 may be different. The arrangement structure of the plurality of combination holes 31 on the elastic plate 30 can be designed according to the pressure distribution of the sole of the foot. The greater the force in the area, the greater the arrangement density of the combination holes 31. In this embodiment, the density of the combination holes 31 arranged in the forefoot and heel of the elastic plate 30 is greater than the density of the combination holes 31 arranged in the arch of the foot of the elastic plate 30. In addition, the elastic plate 30 is also provided with a plurality of round perforations 34, which helps to further increase the deformation capacity of the elastic plate 30.

[0037] Preferably, in this embodiment, the elastic plate 30 is provided with a plurality of elongated holes 35 near its periphery, and the elongated holes 35 may be straight holes or arc-shaped holes, thereby forming an annular multi-segment line structure on the elastic plate 30, and each combination hole 31 and each circular through-hole 34 are located in the space surrounded by the plurality of elongated holes 35, and the soft midsole 10 and the hard midsole 20 are interconnected at each elongated hole 35, each combination hole 31 and each circular through-hole 34, which helps to improve the integrity and service life of the sole.

[0038] Preferably, in the present embodiment, in each combination hole 31 located at the forefoot and arch portion of the elastic plate 30, the arrangement direction of each circular hole 32 of the same combination hole 31 gradually inclines toward the outer side of the shoe from front to back, and in each combination hole 31 located at the heel portion of the elastic plate 30, the arrangement direction of each circular hole 32 of the same combination hole 31 gradually inclines toward the inner side of the shoe from front to back, which helps to improve the stability of the sole.

[0039] Preferably, in this embodiment, the arch portion of the elastic plate 30 is arranged to be gradually tilted downward from the inside to the outside of the shoe, forming a structure that is higher inside and lower outside, which can improve the stability of the inner arch support and the outer arch landing of the sole.

[0040] In addition, an elastic strip 40 is embedded on the outside of the soft midsole 10, and the elastic strip 40 is preferably a TPU strip. The outside of the elastic plate 30 is arranged in a first wave shape at the arch and heel of the shoe, and the elastic strip 40 is arranged in a second wave shape at the position corresponding to the arch and heel of the elastic plate 30. The troughs of the first wave shape and the second wave shape gradually transition from a corresponding arrangement to a staggered arrangement from back to front to provide better shock absorption support.

[0041] Preferably, a rubber sheet 50 is also adhered to the bottom of the hard midsole 20 to improve the wear resistance of the sole.

[0042] The utility model is described in detail above with reference to the accompanying drawings, but the implementation of the utility model is not limited to the above implementation. Those skilled in the art can make various equivalent substitutions for the utility model based on the prior art, which all belong to the protection scope of the utility model.
