Description

Technical Field

[0001] This application relates to the technical field of shoes, and particularly to a wear-resistant and anti-slip shoe sole. Background Art

[0002] Shoes can protect the wearer's feet and facilitate walking. Generally, shoes include a shoe sole and a shoe upper, and the shoe sole plays a role in protecting the sole of the foot during daily wear. During daily walking and running, the front part and the heel part of the shoe sole are the parts that are most likely to rub against the ground. Therefore, the wear resistance of the front part and the heel part of the shoe sole needs to be higher than that of the arch part.

[0003] Since most shoe soles adopt an integrated design, in order to avoid slipping of the shoe sole, anti-slip materials are generally used, but the wear resistance of this material is poor. After long-term use, the wear of the front part and the heel part of the shoe sole will be much greater than that of the arch part. Therefore, it is easy to be damaged and needs further improvement. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a wear-resistant and anti-slip shoe sole.

[0005] The wear-resistant and anti-slip shoe sole has a length direction and a width direction. The shoe sole has a front sole area, a sole center area, and a rear heel area along the length direction, and has opposite inner and outer sides along the width direction. The front sole area has a first gasket relatively located on the inner side and a second gasket relatively located on the outer side, and the rear heel area has a first gasket relatively located on the outer side and a second gasket relatively located on the inner side.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0028] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there may also be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0030] In this application, terms such as "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity or order of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0031] In this application, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a system, product, or device comprising a series of units does not necessarily have to be limited to those units clearly listed, but may include other units not clearly listed or inherent to these products or devices.

[0032] The sole 200 has opposite inner and outer sides. The position where the big toe 210 is located is the inner side, and the position where the little toe 220 is located is the outer side. For example Figure 1 As shown, the Y1 direction is the inner side and the Y2 direction is the outer side.

[0033] When walking, the acting force of the sole 200 is mainly concentrated on Figure 1 the curved positions in, that is, the inner side of the sole 200 and the outer side of the heel. The acting forces at these two positions on the sole 100 are relatively large. However, the existing sole 100 is generally an integral structure with anti-slip function, and the wear resistance of this type of sole 100 is poor. After long-term use, the wear degree of the front sole and the heel positions is relatively large and it is easy to be damaged.

[0034] To solve this problem, refer to Figure 2 , an embodiment of the present application provides a wear-resistant and anti-slip sole 100, which has a length direction and a width direction. The sole 100 has a forefoot area 110, a midfoot area 120, and a heel area 130 along the length direction, and has opposite inner and outer sides along the width direction. For ease of understanding, refer to Figure 2 , where the X1 direction is the length direction, the X2 direction is the width direction, and the inner and outer sides are relative to the corresponding worn sole 200. In this embodiment, the inner side corresponds to Figure 1 Y1 in Figure 1 Y2 in

[0035] Furthermore, the forefoot area 110 has a first gasket 101a relatively located on the inner side and a second gasket 103a relatively located on the outer side, and the heel area 130 has a first gasket 101b relatively located on the outer side and a second gasket 103b relatively located on the inner side.

[0036] Since the position where the sole 200 exerts a large force corresponds to the first gasket 101 of the sole 100, and the position where the sole 200 exerts a small force corresponds to the second gasket 103 of the sole 100, the hardness of the first gasket 101 needs to be greater than the hardness of the second gasket 103, that is, the first gasket 101 is a wear-resistant area, and the second gasket 103 is an anti-slip area.

[0037] For the sole of the present application, when the sole 200 is walking, the position where the sole 200 exerts a large force corresponds to the first gasket 101 of the sole 100, and the part where the force is small corresponds to the second gasket 103 of the sole 100. Compared with the prior art, it takes into account the requirements of wear resistance and anti-slip, and the sole 100 has a longer service life.

[0038] To facilitate the installation of the first gasket 101 and the second gasket 103, the sole 100 has corresponding installation grooves 112, where the thickness of the first gasket 101 and the second gasket 103 is greater than the thickness of the installation grooves 112, so that the first gasket 101 and the second gasket 103 can contact the ground during walking. Preferably, the thicknesses of the first gasket 101 and the second gasket 103 are the same.

[0039] In this embodiment, the number of the first gaskets 101 in the forefoot area 110 is 2, and the number of the second gaskets 103 is 3. Drainage grooves 111 are formed between adjacent gaskets to have a better drainage effect.

[0040] Refer to Figure 2, the first gasket 101 is provided with a first protrusion 102, and the second gasket 103 is provided with a second protrusion 104. The first protrusions 102 are arranged and extended along a first direction (the first direction is the L1 direction in the figure), and the second protrusions 104 are arranged and extended along a second direction (the second direction is the L2 direction in the figure). The first direction is different from the second direction.

[0041] Furthermore, the first direction and the second direction are skewed with respect to both sides of the length direction. Preferably, the angle between the first direction and the length direction is 40° to 70°. In this embodiment, multiple rows of the first protrusions 102 are provided. Each row of the first protrusions 102 is formed by sorting multiple identical patterns. The patterns between adjacent two rows are arranged in a staggered manner. For example, the pattern in the figure is N, and N has two opening directions, and the opening directions are substantially the same as the orientation of the thumb 210 (to form a streamlined structure) to reduce the resistance during walking and make the movement more labor-saving.

[0042] The function of the second protrusion 104 is anti-slip, that is, it is necessary to increase the friction force. Therefore, in this embodiment, the angle between the first direction and the second direction is 80° to 100°. That is, both sides of N are substantially perpendicular to the orientation of the thumb 210 to obtain a larger friction force.

[0043] Of course, the patterns in the first protrusion 102 and the second protrusion 104 can also be adaptively selected according to requirements, and no special requirements are made if not applied.

[0044] To improve the shock absorption effect, a shock absorption portion 131 is provided at the middle position of the heel area 130. The first gasket 101b and the second gasket 103b surround each other to form the shock absorption portion 131. The shock absorption portion 131 is a cavity structure. When the heel hits the ground, the cavity structure will evenly disperse the force received in all directions to achieve a shock absorption effect.

[0045] Of course, considering the stability of the sole 100, an anti-twist plate 121 is also provided in the arch area 120. In order to adaptively select whether to install the anti-twist plate 121 according to requirements, a positioning groove for installing the anti-twist plate 121 can be provided in the arch area 120 to provide two types of soles. When the usage scenario is low-intensity exercise, such as jogging and brisk walking, the anti-twist plate 121 may increase the weight and hardness, affect the comfort, and increase the fatigue. At this time, the sole without the anti-twist plate 121 can be selected. In high-intensity exercise scenarios, such as basketball, football, mountain climbing, and fitness training, the anti-twist plate 121 can enhance the anti-torsion ability of the sole, reduce the deformation of the sole, prevent the ankle from over-inverting or over-everting, provide the stability of the arch and the ankle, and reduce the risk of sprain. For these users, the sole with the anti-twist plate 121 can be selected.

[0046] The two types of soles are produced by the same mold, and the functions are only distinguished by whether the anti-twist plate is installed, reducing the development cost and production complexity.

[0047] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification. When the technical features in different embodiments are embodied in the same drawing, the drawing can be regarded as simultaneously disclosing the combination examples of the respective embodiments involved.

[0048] The above-described embodiments merely represent several implementation manners of the present application, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
