Description

Technical Field

[0001] The utility model relates to the field of shoe structures, in particular to a degradable shock-absorbing sole and a shoe. Background Art

[0002] At present, in the field of shoemaking, plastic and rubber and other materials are usually used to make soles. However, the rubber and plastic currently used are all obtained by polymerizing monomers such as ethylene, propylene, butadiene, etc. extracted from petroleum, which consumes a large amount of petroleum resources. In addition, as for the environment, since the soles of rubber and plastic materials are non-degradable, they cause great pollution to the environment. In addition, the soles made of some plastic materials are high in hardness and cannot reduce the impact force brought by the human body when walking and running, and the shock absorption effect is poor. Utility Model Content

[0003] The embodiment of the utility model provides a degradable shock-absorbing sole and a shoe to solve the problems existing in the related art. The technical solution is as follows:

[0004] In a first aspect, an embodiment of the utility model provides a degradable shock-absorbing sole, comprising:

[0005] The degradable outsole has a contact surface and an outer side surface, wherein the contact surface and the outer side surface are combined to form an inner cavity;

[0006] The degradable foaming layer is arranged in the sunken cavity, the thickness of the rear foot part of the degradable foaming layer is greater than the thickness of the front foot part, and a plurality of holes are arranged on the degradable foaming layer.

[0007] In one embodiment, the degradable outsole is a bio-based rubber outsole.

[0008] In one embodiment, the degradable foam layer is a bio-based polyurethane foam core layer.

[0009] In one embodiment, a plurality of grooves are provided on the outer side surface, and the height of the grooves changes with the height of the outer side surface.

[0010] In one embodiment, a shoe edge extends upward at the toe portion of the outer side.

[0011] In one embodiment, the height of the rear foot portion of the lateral side is greater than the height of the forefoot portion.

[0012] In one embodiment, the through-hole depth of the holes is at least half of the thickness of the degradable foam layer.

[0013] In one embodiment, an anti-slip groove is provided at the bottom of the ground contact surface.

[0014] In one embodiment, the toe portion of the ground contact surface is tilted away from the ground.

[0015] In a second aspect, an embodiment of the utility model provides a shoe, characterized in that it includes the degradable shock-absorbing sole as described above.

[0016] The advantages or beneficial effects of the above technical solution include at least:

[0017] The sole of the utility model is provided with a degradable outer sole and a degradable foaming layer. The entire sole is made of degradable materials, and a plurality of holes are provided on the degradable foaming layer, which can reduce the materials used in shoemaking. Compared with traditional rubber materials, the sole has better environmental adaptability, renewability and resource sustainability.

[0018] At the same time, the degradable foam layer is arranged in the inner cavity formed by the ground contact surface and the outer side surface. Since the degradable foam layer is a layer structure made by a foaming process, the texture is relatively soft and has a certain elasticity. It can return to its original shape after compression, so that the sole has a good shock-absorbing effect.

[0019] In addition, the rear foot part of the degradable foam layer is relatively thick, which makes the compressibility of the rear foot part relatively large. During the process of walking and lifting the foot, the rear foot part of the degradable foam layer rebounds, making the rear foot part of the degradable foam layer fit more closely to the rear foot, which can better cushion the impact caused by the next downward pressure of the sole of the foot and further enhance the shock absorption effect.

[0020] The above summary is for the purpose of description only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the utility model will be readily apparent by reference to the accompanying drawings and the following detailed description.

[0024] In the following, only some exemplary embodiments are briefly described.

Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] Embodiment 1

[0026] At present, in the field of shoemaking, plastic and rubber and other materials are usually used to make soles. However, the rubber and plastic currently used are all obtained by polymerizing monomers such as ethylene, propylene, butadiene, etc. extracted from petroleum, which consumes a large amount of petroleum resources. In addition, as for the environment, since the soles of rubber and plastic materials are non-degradable, they cause great pollution to the environment. In addition, the soles made of some plastic materials are high in hardness and cannot reduce the impact force brought by the human body when walking and running, and the shock absorption effect is poor.

[0027] In order to solve the above problems, the present embodiment provides a degradable shock-absorbing sole, which is made of degradable materials and can achieve good shock-absorbing effects, thereby improving the user's walking experience.

[0028] like Figure 1 As shown, the degradable shock-absorbing sole specifically includes a degradable outsole 100 and a degradable foaming layer 200 .

[0029] Among them, the degradable outsole 100 is a bio-based rubber outsole, and the degradable foaming layer 200 is a bio-based polyurethane foaming filling layer; the bio-based material is an industrial soybean extract, and the bio-based rubber refers to a new type of material made by mixing natural rubber or synthetic rubber with bio-based materials. The raw materials of the bio-based rubber material can use a variety of bio-based materials, such as biomass starch, cellulose, etc., to achieve the purpose of degradation. The bio-based polyurethane foaming filling layer also uses bio-based materials and is degradable. At the same time, the layer structure made by the foaming process has a number of micropores. The presence of micropores makes the layer structure have good elasticity, so that the texture of the degradable foaming layer 200 is relatively soft and has a certain elasticity. The degradable foaming layer 200 produces a certain degree of deformation after being squeezed by the sole of the foot. When the sole of the foot is lifted during walking, it rebounds to restore the deformation. At the same time, it provides a certain support force for the sole of the foot, making walking more comfortable.

[0030] The degradable outsole 100 of this embodiment has a ground contact surface 101 and an outer side surface 103. The bottom of the ground contact surface 101 is provided with an anti-skid groove 102 to prevent the sole from slipping during walking; the outer side surface 103 surrounds the ground contact surface 101 so that the degradable outsole 100 forms an inwardly concave cavity, and the degradable foam layer 200 is filled in the inwardly concave cavity. The thickness of the rear foot part of the degradable foam layer 200 is greater than that of the forefoot part, so that the rebound amount of the rear foot part of the degradable foam layer 200 is relatively large; during walking, the sole of the foot presses on the degradable foam layer 200, and the compression of the rear foot part of the degradable foam layer 200 is relatively large; during the process of lifting the foot, the degradable foam layer 200 The rear foot part rebounds, providing a certain supporting force for the rear foot during the rebound process. At the same time, the rear foot part of the degradable foam layer 200 rebounds so that the rear foot part and the rear foot are closely fitted. The degradable foam layer 200 that has recovered its deformation can continue to prepare for cushioning the impact caused by the next downward pressure of the sole of the foot, reducing the gap between the sole of the foot and the degradable foam layer 200, so that the impact of the sole of the foot on the entire sole can be directly cushioned by the degradable foam layer 200, reducing the additional vibration caused by the direct collision between the sole of the foot and the sole during walking, further improving the shock absorption effect, and avoiding the situation where the heel of the shoe falls off due to excessive gap between the sole of the foot and the sole during the foot lifting process, thereby improving the wearing comfort of users.

[0031] In addition, the thickness of the rear foot part of the degradable foam layer 200 is greater than that of the forefoot part, and the toe position of the ground contact surface 101 is tilted away from the ground, so that when the sole of the foot is in a flat state, the height difference between the rear heel and the forefoot toe is relatively small, further improving the wearing comfort.

[0032] The height of the rear foot part of the outer side surface 103 is higher than that of the forefoot part, so that the outer side surface 103 can completely wrap the degradable foam layer 200 to prevent the degradable foam layer 200 from falling off the degradable outsole 100; at the same time, when the degradable foam layer 200 is pressed down by the sole of the foot, the degradable foam layer 200 is compressed and sinks to a certain depth, and the outer side surface 103 extending upward from the rear foot part can protect the sole of the foot, stabilize the position of the sole of the foot, and prevent sprains caused by unstable rear foot.

[0033] A plurality of grooves 104 are provided on the outer side surface 103, and the height of the grooves 104 changes with the height of the outer side surface 103. The presence of the grooves 104 can reduce the amount of degradable material used on the outer side surface 103; at the same time, the thickness of the outer side surface 103 is thinned, the flexibility of the outer side surface 103 is increased, and the wearing comfort is improved.

[0034] A shoe edge 105 extends upward from the toe portion of the outer side 103 , and the shoe edge 105 can wrap around the toes to protect the toes and prevent the toes from being damaged by external collisions.

[0035] In addition to the micropores generated during the foaming process, the degradable foam layer 200 is provided with a plurality of holes 201. The holes 201 can be evenly distributed on the degradable foam layer 200, which play a role of ventilation and can also save the material consumption of the degradable foam layer 200. The holes 201 can be through holes that penetrate the degradable foam layer 200, or can be semi-hole structures that are not penetrated. The through hole depth of the holes 201 is at least half of the thickness of the degradable foam layer 200. In addition to the role of residual material and ventilation, the holes 201 also provide sufficient compression space for the degradable foam layer 200. When the degradable foam layer 200 is deformed by pressure, the inside of the degradable foam layer 200 can be squeezed into the space where the holes 201 are located, so as to avoid the degradable foam layer 200 being squeezed outward as a whole, resulting in obvious deformation of its appearance.

[0036] In some embodiments, a shoe is further provided, the shoe comprising the above-mentioned sole and upper, the upper and the sole being sewn together to form the shoe. The sole structure in the shoe of this embodiment can refer to the corresponding description in the above-mentioned degradable shock-absorbing sole, which will not be repeated here.

[0037] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model.

In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples, unless they are contradictory.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
