Description

Technical Field

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

[0002] As a necessity of life, shoes are divided into various types according to their uses and the different ground surfaces they are suitable for, such as: warm, breathable, wear-resistant, anti-slip, strong grip, light, etc. Among them, the wear-resistant performance is particularly important as a basic requirement for the sole. A wear-resistant sole refers to a sole made of specific materials or processes that can maintain good wear-resistant performance under long-term use or different terrain conditions, reducing wear and damage.

[0003] However, during the wearing process of shoes, the wear degrees of different parts of the sole are different. Under normal circumstances, the front sole part and the heel part of the sole are worn more severely. When people walk in shoes, the tip of the toe is the main stress point of the foot during walking, and the inner area of the front sole of the shoe will be more severely worn than the outer area; also, the heel is the main stress point of the foot during walking, and the outer area of the heel part of the sole will be worn more severely than the inner area.

[0004] Therefore, after the sole is worn, it is easy for the inner area of the front sole part to be lower than the outer area, and it is also easy for the outer area of the heel part to be lower than the inner area, thereby affecting the comfort of people when walking in shoes, which needs to be improved. Summary of the Utility Model

[0005] Based on this, this application provides a wear-resistant sole, which can make the wear of various areas of the sole more uniform, improve the service life of the sole and the comfort of people's long-term wearing.

[0006] The wear-resistant sole provided by this application adopts the following technical solution:

[0007] A wear-resistant sole includes a sole body, a first wear-resistant bottom sheet embedded in the inner area of the front sole part of the sole body, and a second wear-resistant bottom sheet embedded in the outer area of the heel part of the sole body. The sole body is an EVA sole; both the first wear-resistant bottom sheet and the second wear-resistant bottom sheet are PVC bottom sheets, and anti-slip patterns are provided on the surfaces of both the first wear-resistant bottom sheet and the second wear-resistant bottom sheet.

[0008] By adopting the above technical solution, by arranging the first wear-resistant bottom sheet in the inner area of the inlay part of the shoe sole body and arranging the second wear-resistant bottom sheet in the outer area of the heel part of the shoe sole body, since the wear-resistant performance of the PVC material is better than that of the EVA material, the wear-resistant effects of the first wear-resistant bottom sheet and the second wear-resistant bottom sheet made of the PVC material will be greater than the wear-resistant effect of the shoe sole body, which can improve the wear-resistant performance of the easily worn areas of the shoe sole body, and then make the wear of each area of the shoe sole more uniform, which is beneficial to improving the service life of the shoe sole and the comfort of people wearing it for a long time. The setting of the anti-slip patterns is used to improve the anti-slip effect of the first wear-resistant bottom sheet and the second wear-resistant bottom sheet to overcome the disadvantage of the poor anti-slip effect of the PVC material.

[0009] Optionally, the anti-slip patterns include a plurality of anti-slip grooves provided on the first wear-resistant bottom sheet / the second wear-resistant bottom sheet, and the anti-slip grooves are arranged at intervals along the length direction of the shoe sole body.

[0010] By adopting the above technical solution, when people wear shoes and step on a slippery ground, the first wear-resistant bottom sheet / the second wear-resistant bottom sheet can deform towards the position of the anti-slip grooves, and the degree of deformation is large, which is beneficial to enhancing the friction between the shoes and the ground; at the same time, the accumulated water can quickly drain along the anti-slip grooves, reducing the influence of the water film on the friction, and thus reducing the risk of people slipping.

[0011] Optionally, a plurality of drainage grooves are provided in the outer area of the forefoot part of the shoe sole body, and one end of each drainage groove extends to the outer side surface of the shoe sole body; all the drainage grooves are arranged at intervals along the length direction of the shoe sole body.

[0012] By adopting the above technical solution, when people wear shoes and step on a slippery ground, the drainage grooves can play a major drainage effect, draining the accumulated water at the bottom along the drainage grooves to the outside of the shoe sole body, further reducing the risk of people slipping when walking.

[0013] Optionally, the drainage grooves extend in an arc along the width direction of the shoe sole body.

[0014] By adopting the above technical solution, by making the drainage grooves extend in an arc along the width direction of the shoe sole body, the area of the shoe sole body between adjacent drainage grooves also extends in an arc, which can form frictional resistance in all directions when people walk, play an anti-slip effect, and at the same time have good grip.

[0015] Optionally, a first preset groove and a second preset groove are provided in the arch part of the shoe sole body, and the first preset groove is communicated with the second preset groove; the first preset groove extends obliquely to the inner side surface of the shoe sole body, and the second preset groove extends obliquely to the outer side surface of the shoe sole body.

[0016] By adopting the above technical solution, the first preset groove and the second preset groove are formed in the arch part of the sole body, which can play a role in assisting drainage and guiding the accumulated water to the inner and outer sides of the sole body. Moreover, when people walk wearing the shoes, the arch part of the sole body will generate a large deformation. The settings of the first preset groove and the second preset groove can serve as the pre-deformation areas of the arch part, which is beneficial to reducing the situation of local cracking in the arch part and enabling the sole body to maintain a good service life.

[0017] Optionally, a deformation groove area for the sole body to be deformed under force is provided in the inner area of the heel part of the sole body.

[0018] By adopting the above technical solution, the second wear-resistant bottom sheet made of pvc material has a relatively hard texture. When people walk, the deformation of the heel part of the sole body is more concentrated in the inner area of the heel part. The setting of the deformation groove area can serve as the pre-deformation area of the heel part, which is beneficial to reducing the situation of local cracking in the heel part and enabling the sole body to maintain a good service life.

[0019] Optionally, a plastic film sleeve is covered and bonded to the outer surface of the sole body. The plastic film sleeve covers the deformation groove area, and air cushion particles are provided between the plastic film sleeve and the deformation groove area.

[0020] By adopting the above technical solution, by setting air cushion particles with high resilience ability, the resilience of the sole body can be improved. Furthermore, when people exercise wearing the shoes, good comfort can be maintained, and the fatigue of the feet can be reduced.

[0021] Optionally, a varnish layer is coated on the surface of the plastic film sleeve.

[0022] By adopting the above technical solution, the setting of the varnish layer can reduce the occurrence of external dirt adhering to the plastic film sleeve and improve the cleanliness of the surface of the sole body.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The wear-resistant effect of the second wear-resistant bottom sheet made of pvc material and the second wear-resistant bottom sheet is greater than that of the sole body, which can improve the wear-resistant performance of the wear-resistant area of the sole body. Furthermore, the wear of each area of the sole is relatively uniform, which is beneficial to improving the service life of the sole and the comfort of people wearing it for a long time;

[0025] 2. By making the drainage grooves extend in an arc along the width direction of the sole body, the areas of the sole body between adjacent drainage grooves also extend in an arc, which can form frictional resistance in all directions when people walk, achieving an anti-slip effect and having good grip at the same time;

[0026] 3. By setting air cushion particles with high resilience ability, the elasticity of the sole body can be improved, thereby maintaining good comfort when people wear shoes to exercise and reducing foot fatigue. Description of the Drawings

Detailed Description of the Embodiment

[0030] The following further describes the present application in detail Figure 1-2 with reference to the accompanying drawings.

[0031] The embodiment of the present application discloses a wear-resistant sole.

[0032] Referring to Figure 1 , a wear-resistant sole includes a sole body 1, a first wear-resistant bottom sheet 2 and a second wear-resistant bottom sheet 3. Among them, the first wear-resistant bottom sheet 2 is embedded in the inner area of the forefoot part 11 of the sole body 1, and the second wear-resistant bottom sheet 3 is embedded in the outer area of the heel part 12 of the sole body 1; the sole body 1 in this embodiment is obtained by foaming an EVA material, and both the first wear-resistant bottom sheet 2 and the second wear-resistant bottom sheet 3 are processed from PVC materials.

[0033] When people walk in shoes, the inner area of the forefoot part 11 of the sole is more severely worn than the outer area, and the outer area of the heel part 12 of the sole is also more severely worn than the inner area, forming an easily worn area; the wear-resistant effect of the first wear-resistant bottom sheet 2 and the second wear-resistant bottom sheet 3 made of PVC material is greater than that of the sole body 1, which can improve the wear-resistant performance of the easily worn areas of the sole body 1, make the wear of each area of the sole more uniform, so as to improve the service life of the sole and the comfort of people wearing it for a long time.

[0034] The surfaces of the first wear-resistant sole 2 and the second wear-resistant sole 3 are both provided with anti-slip patterns 4. The anti-slip patterns 4 include a plurality of anti-slip grooves 41 formed in the first wear-resistant sole 2 / second wear-resistant sole 3. Each of the anti-slip grooves 41 is arranged at intervals along the length direction of the sole body 1. At the same time, each anti-slip pattern 4 extends through both side edges of the first wear-resistant sole 2 / second wear-resistant sole 3 along the width direction of the sole body 1. The setting of the anti-slip grooves 41 is used to enhance the friction between the shoes and the ground, and at the same time plays the role of draining accumulated water, reducing the influence of the water film on the friction force.

[0035] In the specific foaming and molding process of this wear-resistant sole, the first wear-resistant sole 2 and the second wear-resistant sole 3 made of pvc material are relatively hard. By setting protrusions inside the foaming mold, the first wear-resistant sole 2 and the second wear-resistant sole 3 are pre-fixed inside the foaming mold through the cooperation between the anti-slip grooves 41 and the protrusions and are not easy to fall off. Then, the eva material is injected into the foaming mold, and it is pressurized and heated to foam to form the sole body 1, which can firmly fix the first wear-resistant sole 2 and the second wear-resistant sole 3 to the sole body 1 and is not easy to separate.

[0036] In addition, a plurality of drainage grooves 5 are provided in the outer region of the front sole part 11 of the sole body 1, which is used to achieve the main drainage effect and can reduce the risk of slipping when people wear shoes and step on a slippery ground. All the drainage grooves 5 are arranged at intervals along the length direction of the sole body 1. Among them, the drainage grooves 5 can extend in an arc shape along the width direction of the sole body 1, so that each drainage groove 5 forms a regular divergent shape. One end of the drainage groove 5 extends to the outer side surface of the sole body 1, and the other end extends to the outside of the first wear-resistant sole 2.

[0037] A first preset groove 6 and a second preset groove 7 are formed in the arch part 13 of the sole body 1. The first preset groove 6 is connected to the second preset groove 7. The first preset groove 6 extends obliquely along the length direction of the sole body 1 to the inner side surface of the sole body 1, and the second preset groove 7 extends obliquely along the length direction of the sole body 1 to the outer side surface of the sole body 1, and the extension directions between the first preset groove 6 and the second preset groove 7 are opposite, so that the first preset groove 6 and the second preset groove 7 form a "√" shape as a whole.

[0038] The settings of the first preset groove 6 and the second preset groove 7 can play an auxiliary drainage role, reduce the risk of slipping when people walk on a slippery ground, and at the same time can be used as a pre-deformation area of the arch part 13, which is beneficial to reducing the local cracking of the arch part 13 and keeping the sole body 1 in good service life.

[0039] Refer to Figure 2, an indented deformation groove area 8 is provided in the inner area of the heel part 12 of the sole body 1. The deformation groove area 8 can serve as a pre-deformation area for the sole heel part 12 to deform, thereby reducing the situation of local cracking of the heel part 12. The inner edge of the heel part 12 of the sole body 1 is also covered with a plastic film sleeve 9. The circumferential edge of the plastic film sleeve 9 can be adhesively fixed to the sole body 1, and the plastic film sleeve 9 covers the deformation groove area 8; air cushion particles 81 are filled between the plastic film sleeve 9 and the deformation groove area 8. The air cushion particles 81 can improve the resilience of the sole body 1 and can reduce the fatigue of the feet when people are exercising. In addition, a varnish layer 91 is also coated on the surface of the plastic film sleeve 9 to reduce the situation of external dirt adhering to the plastic film sleeve 9 and improve the cleanliness of the surface of the sole body 1.

[0040] The above is the preferred embodiment of this application, and the protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
