DETAILED DESCRIPTION
[0029] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.
[0030] Example 1
[0031] Figure 1 The structure diagram of the shock-absorbing, wear-resistant and anti-skid injection-molded sole provided by the first embodiment of the present invention is shown.
[0032] like Figure 1 As shown, the shock-absorbing, wear-resistant and non-slip injection-molded sole includes:
[0033] An injection molded layer 10, the injection molded layer 10 having a cavity extending along the length direction of the injection molded layer 10;
[0034] The wear-resistant and anti-slip layer 20 is provided at the bottom of the injection-molded layer 10. The bottom of the wear-resistant and anti-slip layer 20 has grooves 21 and ridges 22. The grooves 21 and the ridges 22 are spaced apart from each other. The extension direction of the grooves 21 and the extension direction of the ridges 22 are the length direction of the wear-resistant and anti-slip layer 20.
[0035] The shock absorbing layer 30 is disposed in the cavity of the injection molded layer 10 , and the shock absorbing layer 30 is located between the wear-resistant and anti-slip layer 20 and the injection molded layer 10 .
[0036] In the shock-absorbing, wear-resistant and non-slip injection-molded sole of the present invention, the injection-molded layer is provided with a cavity, which extends along the length direction of the injection-molded layer 10, and the shock-absorbing layer 30 is provided in the cavity. The shock-absorbing layer 30 is located between the wear-resistant and non-slip layer 20 and the injection-molded layer 10, so that the shock-absorbing layer 30 can extend in the length direction of the injection-molded layer 10, thereby buffering the impact force when the forefoot of the human foot lands on the ground and the impact force when the heel lands on the ground during walking, and improving the rebound performance of the shock-absorbing, wear-resistant and non-slip injection-molded sole. In addition, the rebound performance is better than that of only providing the shock-absorbing layer on the part of the sole corresponding to the heel of the human body, which can bring better comfort to users. For a more comfortable experience; and, by arranging a wear-resistant and anti-skid layer 20 at the bottom of the injection molded layer 10, the bottom of the wear-resistant and anti-skid layer 20 has grooves 21 and ridges 22, and the grooves 21 and the ridges 22 are spaced apart from each other, and the extension direction of the grooves 21 and the extension direction of the ridges 22 are the length direction of the wear-resistant and anti-skid layer 20. On the one hand, the wear of the shock-absorbing, wear-resistant and anti-skid injection molded sole can be reduced, and on the other hand, the grooves 21 and the ridges 22 can enhance the gripping effect of the shock-absorbing, wear-resistant and anti-skid injection molded sole on the ground, so that the shock-absorbing, wear-resistant and anti-skid injection molded sole can maintain a long-term anti-skid effect, thereby improving the anti-skid effect of the shock-absorbing, wear-resistant and anti-skid injection molded sole.
[0037] For example, the injection molding layer 10 can be fixed on the shock absorbing layer 30 by hot melting. For example, the injection molding layer 10 is injected into the bottom mold in liquid form and fused with the surface of the shock absorbing layer 30 and then solidified, thereby fixing the injection molding layer 10 and the shock absorbing layer 30 together.
[0038] For example, the injection molding layer 10 and the shock absorbing layer 30 can be fixed to the wear-resistant and anti-slip layer 20 by an adhesive. For example, when the injection molding layer 10 is injected into the bottom mold in liquid form, it is bonded to the wear-resistant and anti-slip layer 20 that has been brushed with adhesive after curing. Correspondingly, when the shock absorbing layer 30 is injected into the bottom mold in liquid form, it can also be bonded to the wear-resistant and anti-slip layer 20 that has been brushed with adhesive after curing.
[0039] In one embodiment, the material of the shock absorbing layer 30 is a polyurethane foam high-elastic shock absorbing material. Such a setting can make the shock absorbing layer 30 have high rebound performance and good chemical stability, thereby improving the rebound performance of the shock absorbing, wear-resistant and non-slip injection molded sole.
[0040] In one embodiment, the material of the injection molding layer 10 is polyurethane injection molding material. Such a setting can make the injection molding layer 10 have good stability, chemical resistance, resilience and mechanical properties, which helps to improve the resilience performance of the shock-absorbing, wear-resistant and anti-slip injection molding sole.
[0041] In specific implementation, the injection molding layer 10 can be manufactured using the existing machine injection process.
[0042] In one embodiment, the material of the wear-resistant and anti-skid layer 20 is a wear-resistant and anti-skid rubber material. Such a setting can make the wear-resistant and anti-skid layer 20 have good shock absorption, wear resistance, high temperature resistance and other properties, thereby improving the anti-skid effect of the shock-absorbing, wear-resistant and anti-skid injection molded sole.
[0043] In specific implementation, when the material of the wear-resistant and anti-slip layer 20 is a wear-resistant and anti-slip rubber material, it can support changing different colors, that is, the wear-resistant and anti-slip layer 20 can be set to multiple colors, so as to meet the personalized needs of different users.
[0044] In one embodiment, the injection molded layer 10 has a first heel portion 11, a first toe portion 12, and a first recess 13 located between the first heel portion 11 and the first toe portion 12; the shock absorbing layer 30 has a second heel portion 31, a second toe portion 32, and a second recess 33 located between the second heel portion 31 and the second toe portion 32. The first heel portion 11 and the second heel portion 31 are arranged in correspondence with each other, the first toe portion 12 and the second toe portion 32 are arranged in correspondence with each other, and the first recess 13 and the second recess 33 are arranged in correspondence with each other. This arrangement can conform to the physiological structure of the human foot, thereby improving the comfort of the shock absorbing, wear-resistant, and non-slip injection molded sole.
[0045] In a specific implementation, the sizes of the areas where the first recess 13 and the second recess 33 are located may be determined by the physiological structure of the human foot, and the present invention does not impose any limitation thereto.
[0046] In one embodiment, the thickness of the first heel portion 11 decreases gradually from the end away from the first recess 13, and the thickness of the second heel portion 31 is consistent with the thickness of the first heel portion 11; the thickness of the first recess 13 decreases gradually from the end away from the first toe portion 12, the maximum thickness of the first recess 13 is the same as the minimum thickness of the first heel portion 11, and the thickness of the second recess 33 is consistent with the thickness of the first recess 13; the thickness of the first toe portion 12 is the same as the minimum thickness of the first recess 13, and the thickness of the second toe portion 32 is consistent with the thickness of the first toe portion 12.
[0047] Since the impact force when the forefoot of a human foot touches the ground is generally smaller than the impact force when the heel touches the ground during walking, the present invention sets the thickness of the first heel portion 11 and the thickness of the second heel portion 31 to be larger, and the first heel portion 11 and the second heel portion 31 to correspond to the heel of the human foot, and the thickness of the first toe portion 12 and the thickness of the second toe portion 32 to be smaller, and the first toe portion 12 and the second toe portion 32 to correspond to the front toe of the human foot. In this way, the comfort of the shock-absorbing, wear-resistant and non-slip injection-molded sole can be improved while taking into account the impact of cushioning when the forefoot touches the ground and the impact of the heel touches the ground.
[0048] In a specific implementation, the first heel portion 11 , the first toe portion 12 and the first recess 13 are integrally provided, and the second heel portion 31 , the second toe portion 32 and the second recess 33 are integrally provided.
[0049] In one embodiment, the orthographic projection of the shock-absorbing layer 30 and the orthographic projection of the injection-molded layer 10 are located within the orthographic projection of the wear-resistant and anti-skid layer 20. This arrangement allows the shock-absorbing, wear-resistant and anti-skid injection-molded sole to completely cover the sole area of the human foot with its gripping area, further enhancing the anti-skid effect of the shock-absorbing, wear-resistant and anti-skid injection-molded sole.
[0050] In specific implementation, the lower end projection of the wear-resistant and anti-skid layer 20 can also be set to completely cover the upper end projection of the wear-resistant and anti-skid layer 20, so as to increase the grip area of the shock-absorbing, wear-resistant and anti-skid injection-molded sole on the ground, and further improve the anti-skid effect of the shock-absorbing, wear-resistant and anti-skid injection-molded sole.
[0051] In one embodiment, the upper end of the shock-absorbing layer 30 has a plurality of material-saving holes 34 along its length. This configuration can save material for the shock-absorbing layer 30, reduce the cost of the shock-absorbing, wear-resistant, and non-slip injection-molded sole, and at the same time, reduce the weight of the shock-absorbing, wear-resistant, and non-slip injection-molded sole and increase its softness.
[0052] As an example, the plurality of material-saving holes 34 may be regularly distributed, such as in a matrix distribution, etc., which is not limited in the present invention.
[0053] In specific implementation, the material-saving hole 31 can be set to be cylindrical. Of course, the material-saving hole 31 can also be set to other shapes, and the present invention is not limited to this.
[0054] In the first embodiment of the present invention, the shock-absorbing, wear-resistant and anti-skid injection-molded sole has good anti-skid effect, good rebound performance and the like.
[0055] Example 2
[0056] A second embodiment of the present invention provides a shoe comprising any possible implementation of the shock-absorbing, wear-resistant and non-slip injection-molded sole described in the first embodiment.
[0057] In summary, the shock-absorbing, wear-resistant and anti-skid injection-molded sole and shoes provided by the utility model have good anti-skid effect, good rebound performance and the like.
