Description

Technical Field

[0001] The utility model belongs to the technical field of shoes, and particularly relates to a breathable shoe upper. Background Art

[0002] Shoes are daily items consisting of uppers, insoles, soles and heels, used to protect the human foot. Shoes have a certain degree of water vapor permeability in the sole and upper areas, also known as breathability. During outdoor sports, the feet produce a lot of sweat, which is difficult to evaporate quickly. Long-term sweat soaking can easily lead to various foot diseases. The breathability of the shoe upper is particularly important, which can enhance the air circulation inside the shoe cavity, enhance the circulation of the gas inside the shoe cavity and the fresh air outside, and improve the internal environment of the shoe.

[0003] The materials used for existing shoe uppers are mostly leather or cloth. However, shoes made of leather or cloth have the problem of poor air permeability in the shoe upper area. Even the shoe uppers made of mesh cloth still have insufficient air permeability. Utility Model Content

[0004] The purpose of the embodiment of the utility model is to provide a breathable shoe upper, aiming to solve the problem of poor air permeability.

[0005] The embodiment of the utility model is implemented as follows: a breathable shoe upper, the breathable shoe upper includes a plurality of curved surface pieces, the side edges of the plurality of curved surface pieces overlap each other to form the breathable shoe upper; a plurality of ventilation holes are arranged at the overlapped portions of the curved surface pieces.

[0006] Preferably, the curved sheet is provided with a plurality of guide fins, and two adjacent curved sheets overlap on the guide fins to form the air holes.

[0007] Preferably, the ventilation holes are oriented toward the toe of the shoe, and the guide fins extend toward the rear of the shoe.

[0008] Preferably, the breathable shoe upper formed by a plurality of the curved pieces is an integrally formed structure.

[0009] Preferably, the breathable upper is formed by 3D printing.

[0010] Preferably, the raw material for 3D printing is nylon or TPU powder.

[0011] The embodiment of the utility model provides a breathable upper. The upper of the present application is composed of alternately overlapping curved pieces. The curved pieces that constitute the upper are arranged in different heights, and the air holes are not arranged on a fixed plane. This makes it easier for air to enter the inside of the shoe along the air holes when a person walks, and the shoe has a better ventilation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] like Figure 1-3 As shown, in one embodiment, a breathable shoe upper is provided, the breathable shoe upper comprising a plurality of curved sheets 1, the side edges of the plurality of curved sheets 1 overlap with each other to form the breathable shoe upper; a plurality of air holes 2 are provided at the overlapped portions of the curved sheets 1.

[0019] In this embodiment, the shape of the curved sheet 1 is various, which can be an annular band, and the curved sheets 1 overlap and nest with each other from the toe until the heel position to form the upper; or it can be a streamlined sheet, and the curved sheets 1 overlap and splice with each other to form the upper. The "overlap" described in this embodiment does not mean that the upper and lower parts are completely overlapped, but that the sides of the two adjacent curved sheets 1 are overlapped with each other, and the overlapping width size can be designed according to actual needs. The air vents 2 are arranged at this stacking position. The upper described in this embodiment is different from the upper of a general shoe. The general upper uses a large mesh fabric to improve the ventilation effect, and its air vents are opened on the plane of the mesh fabric. However, the upper of the present application is composed of alternately overlapping curved sheets 1, and the curved sheets 1 constituting the upper are of different heights. The air vents 2 are not arranged on a fixed plane, which makes it easier for airflow to enter the inside of the shoe along the air vents 2 when people walk, and the shoe has a better ventilation effect.

[0020] Preferably, the curved sheet 1 has a plurality of guide fins 3, and two adjacent curved sheets 1 overlap on the guide fins 3 to form the air holes 2. The air holes 2 face the toe of the shoe, and the guide fins 3 extend toward the rear of the shoe. An air outlet 4 is provided at the rear of the upper of the breathable shoe.

[0021] In this preferred embodiment, a plurality of guide fins 3 are arranged in parallel on the inner side of the curved sheet 1, and two adjacent curved sheets 1 and two adjacent guide fins 3 form an air hole 2 to play a role of ventilation; the guide fins 3 are parallel to each other and extend to the rear of the shoe to play a role of guiding. Figure 3 As shown, the direction of the vent holes 2 is from left to right, along the direction of the shoe tip; when a person walks or runs, the foot moves forward, and the air flows into the shoe along the vent holes 2, takes away the heat and water vapor inside the shoe under the guidance of the guide fins 3, and finally is discharged from the air outlet 4 at the rear of the shoe. The guide fins 3 are also provided on the inner side of the air outlet 4 to guide the air.

[0022] Preferably, the breathable upper formed by the plurality of curved sheets 1 is an integrally formed structure. The breathable upper is formed by 3D printing. The raw material of the 3D printing is nylon or TPU powder.

[0023] In this preferred embodiment, 3D printing technology is also called additive manufacturing technology. Different from previous manufacturing methods, 3D printing is based on 3D digital models and constructs object structures by printing layer by layer, eliminating many complex processes in the molding process of industrial products.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
