Description

Technical Field

[0001] The utility model relates to the technical field of soles, and more specifically to an environmentally friendly sole. Background Art

[0002] The sole can be made of only one material or multiple materials distributed in different functional positions (the sole using multiple materials distributed in different functional positions can be as shown in "Application No.: CN201320270411.3, soft and environmentally friendly sole");

[0003] According to the above, different materials and structures of the soles of the shoes have different functions (corresponding to different structural positions, they can be wear-resistant, shock-absorbing, weather-resistant, lightweight, etc.). For example, the outermost layer is usually made of wear-resistant rubber to resist ground friction and extend the service life of the shoes; the middle layer may contain shock-absorbing materials (such as EVA or TPU) to absorb the impact on the feet and body during walking or exercise, and provide comfort; the inner layer is often soft cloth or leather to fit the soles of the feet and improve wearing comfort;

[0004] In order to ensure the environmental friendliness of the sole after production and use, a material "such as recyclable EVA, recyclable rubber, etc." is used to make the overall sole material. In order to ensure the functionality of the corresponding positions of the environmentally friendly sole (such as the functional layer at the corresponding structural position mentioned above), a sole in which the functional layer at the corresponding structural position is made of a reasonable environmentally friendly material is proposed.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a structural schematic diagram of the utility model.

[0017] Reference numerals: functional layer-A, middle bottom layer-1, outer bottom layer-2, stabilizing sheet-3, inner bottom layer-4, cushioning pad-5. DETAILED DESCRIPTION

[0018] like Figure 1 As shown, the utility model proposes: an environmentally friendly sole, comprising a functional layer A of two or more layers of materials connected as one, wherein the functions of the two or more layers of materials of the functional layer A are not completely the same (that is, the functions of the two or more layers of materials may be the same or different when there are at least three or more);

[0019] The material of the sole is recyclable material, the materials of the two or more layers of the functional layer A are functional materials corresponding to the layers, and the materials of the two or more layers of the functional layer A are not completely the same (that is, when the material types of the two or more layers are at least three or more, they may be the same or different);

[0020] To explain the implementation of the functional layer A, it is proposed that Figure 1 As shown, the specific structure and composition of the functional layer A can be as follows: the functional layer A includes a middle bottom layer 1, an outer bottom layer 2 fixedly attached to the bottom end of the middle bottom layer 1, a stabilizing sheet 3 and an inner bottom layer 4 fixedly attached to the top end of the middle bottom layer 1 in sequence, and a buffer pad 5 (such as Figure 1 As shown, the structural composition of the functional layer A can be intuitively understood);

[0021] The stabilizing sheet 3 has the same fitting size as the inner bottom layer 4 and the outer bottom layer 2, and the middle bottom layer 1, the outer bottom layer 2, the stabilizing sheet 3 and the inner bottom layer 4 can be bonded together by bonding or the like; the buffer pad 5 can be provided by pre-setting an opening on the middle bottom layer 1, inserting the buffer pad 5, and then fixing them by bonding or the like;

[0022] The material of the mid-bottom layer 1 is recyclable EVA or polyurethane foam, etc. (recyclability provides environmental protection effects), which is mainly responsible for cushioning and shock absorption, providing comfort for the wearer, and realizing functions such as energy feedback in some sports shoes, providing good cushioning and lightweight characteristics.

[0023] The outer bottom layer 2 is made of recyclable rubber or bio-based rubber (recyclability provides environmental protection), and is used as the shoe contacting the ground, providing wear resistance and weather resistance.

[0024] The material of the stabilizer 3 is TPU or nylon (recyclable and environmentally friendly), which is used to enhance the rigidity and stability of the middle part, prevent excessive torsion, and has strong toughness and impact resistance.

[0025] The inner bottom layer 4 is made of recyclable EVA or polyurethane foam (recyclability provides environmental protection), and as the layer that fits closely to the sole of the foot, it provides additional comfort and support.

[0026] The material of the buffer pad 5 is polyester fiber or the like (recyclable and environmentally friendly). This polyester fiber membrane can withstand great pressure and has good elasticity and durability.

[0027] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
