Description

Technical Field

[0001] The utility model relates to the technical field of shoes, in particular to an environmentally friendly sole structure and a shoe body. Background Art

[0002] Shoes have a long history. The earliest footwear, made of animal hides, appeared during the Yangshao culture over 5,000 years ago. Shoes served as a means of protecting the feet from injury. Fur shoes were first invented to overcome specific conditions and prevent foot discomfort or injury. Over time, footwear has evolved to its current form, with shoes of various styles and functions now commonplace.

A positioning enclosure is arranged around the outer periphery of the upper surface of the sole body, a bending groove is provided at the center height position of the inner side of the positioning enclosure, and a plurality of threading openings are provided at intervals through the lower end of the inner side of the positioning enclosure. The insole includes a padding layer and an elastic positioning layer connected to the lower end surface of the padding layer. The shape and size of the padding layer are respectively consistent with the shape and size of the outer periphery of the positioning enclosure, and the shape and size of the elastic positioning layer are respectively consistent with the shape and size of the inner opening of the positioning enclosure.

[0006] Furthermore, the outer periphery of the top end of the positioning enclosure is chamfered.

[0007] Furthermore, transition opening grooves are provided at the four corners of the top end of the positioning enclosure.

[0008] Furthermore, the outer periphery of the lower end of the elastic positioning layer is chamfered.

[0018] The sole structure of the present invention will be described in more detail below with reference to schematic diagrams, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art may modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as a general guide for those skilled in the art and not as a limitation of the present invention.

[0019] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0020] Example 1

[0021] like Figure 1 As shown, an embodiment of the utility model proposes an environmentally friendly sole structure, including a sole body 1 and an insole 2. A positioning enclosure 3 is arranged around the outer periphery of the upper surface of the sole body 1, a bending groove 31 is provided at the center height position of the inner side surface of the positioning enclosure 3, and a plurality of threading openings 32 are provided at intervals through the lower end of the inner side surface of the positioning enclosure 3. The insole 2 includes a padding layer 21 and an elastic positioning layer 22 connected to the lower end surface of the padding layer 21. The shape and size of the padding layer 21 are respectively consistent with the shape and size of the outer periphery of the positioning enclosure 3, and the shape and size of the elastic positioning layer 22 are respectively consistent with the shape and size of the inner opening of the positioning enclosure 3.

[0022] In this embodiment, for the structure of the sole body 1, the matching upper can be designed to be hollowed out at the lower end (such as Figure 2 As shown), compared with the traditional upper design (such as Figure 3 As shown), it can save a certain amount of material.

[0023] When installing the upper and the sole body 1, first insert the positioning fence 3 into the lower opening of the upper, and fit the positioning fence 3 with the inner wall of the lower opening of the upper to complete the preliminary positioning and installation of the upper and the sole body 1. Then, sew with sutures according to the distribution of the threading holes 32 to complete the final fixation between the upper and the sole body 1. No glue is needed in the whole process.

[0024] When installing the insole 2, first bend the upper end of the positioning enclosure 3 inward. The bending groove 31 facilitates the bending of the positioning enclosure. Then, insert the elastic positioning layer 22 into the inner side of the positioning enclosure 3. The elastic positioning layer 22 will be in close contact with the bent portion of the positioning enclosure 3. At the same time, the bent portion of the positioning enclosure 3 will fit with the lower end of the positioning enclosure 3. The close contact between the elastic positioning layer 22 and the bent portion of the positioning enclosure 3 makes it difficult for the insole 2 to separate from the sole body 1, achieving the purpose of stable installation and eliminating the need for glue. The bent portion of the positioning enclosure 3 fits with the lower end of the positioning enclosure 3, which can seal the threading port 32.

[0025] In summary, the sole structure provided in this embodiment can realize glue-free installation between the upper and the sole body, and can also realize stable installation between the sole body and the insole without using glue, thereby improving the safety and environmental protection during the production and use of shoes.

[0026] In one embodiment, it can be seen that the surrounding contour of the positioning enclosure 3 is consistent with the side surrounding contour of the sole body 1. Based on the sole shape of general shoes, there are a large number of curves on the surrounding contour of the positioning enclosure 3. Therefore, after the positioning enclosure 3 is bent inward, there will be a part with stacked folds. Based on this, preferably, transition opening grooves 33 are opened at the four corners of the top of the positioning enclosure 3.

[0027] In one embodiment, to facilitate the initial positioning and installation of the upper and the sole body 1, the top periphery of the positioning enclosure 3 is chamfered. At the same time, to facilitate the insertion of the elastic positioning layer 22 into the inner side of the positioning enclosure 3, the bottom periphery of the elastic positioning layer 22 is chamfered.

[0028] In one embodiment, the sole body 1 and the positioning enclosure 3 are integrally formed.

[0029] The sole body 1 and the positioning enclosure 3 are integrally formed, which reduces production costs and improves production efficiency.

[0030] Example 2

[0031] The embodiment of the present utility model further provides a shoe body, which adopts the environmentally friendly sole structure in embodiment 1.

[0032] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
