Description

Technical Field

[0001] The utility model relates to the technical field of shoe uppers, in particular to a TPU shoe upper. Background Art

[0002] TPU upper is a thermoplastic upper, which is formed into a breathable upper with pores by hot pressing TPU hot melt lines. TPU upper has advantages such as breathability and wear resistance, but also has disadvantages of poor support performance. TPU upper is easy to deform, and the deformation is large, and the wrapping support performance of the foot is poor, and it cannot protect the foot well. In the prior art, the deformation of the upper is generally limited by compounding leather pieces or webbing on the inner and outer sides of the TPU upper to improve the wrapping support performance of the upper. The wrapping of the TPU upper can be improved by gluing or stitching the composite leather pieces or webbing, but the production process is complicated and requires different equipment to complete gluing or stitching.

[0003] This case arises to solve the above problems. Utility Model Content

[0004] Therefore, in view of the above-mentioned problems, the utility model proposes a TPU shoe upper with good wrapping support and good air permeability.

[0005] In order to solve the above technical problems, the solution adopted by the utility model is: a TPU upper, including a base layer, a shoe opening and a shoe tongue opening are opened on the base layer, and a first reinforcement layer, a second reinforcement layer, and a third reinforcement layer are sequentially stacked on the base layer;

[0006] The first reinforcement layer comprises a first reinforcement track hot-melt line and a plurality of first hot-melt lines, wherein the first reinforcement track hot-melt lines are respectively arranged on both sides of the shoe tongue opening, the first reinforcement track hot-melt lines are laid in an arc shape along one side of the shoe opening to the other side of the toe portion of the bottom base layer, the arc of the first reinforcement track hot-melt line gradually decreases from the shoe opening to the toe portion, a plurality of the first hot-melt lines are arranged tangent to the first reinforcement track hot-melt line, the first hot-melt lines on the same first reinforcement track hot-melt line are located at the middle of the same side of the upper to form a mutually staggered first reinforcement portion, the first hot-melt lines on two first reinforcement track hot-melt lines are located at the toe portion of the bottom base layer to form a mutually staggered second reinforcement portion, and a first breathable portion is formed between the first reinforcement portion and the second reinforcement portion;

[0007] The second reinforcement layer includes a second reinforcement track hot-melt line and a plurality of second hot-melt lines, wherein the second reinforcement track hot-melt line is laid in an arc shape from one side to the other side of the toe portion of the base layer, and the plurality of second hot-melt lines are arranged tangent to the second reinforcement track hot-melt line, and the second hot-melt lines are interlaced to form a third reinforcement portion;

[0008] The third reinforcement layer includes a tongue patch and a back patch. The tongue patch is heat-melted and bonded to both sides of the tongue of the base layer. A plurality of shoelace holes are provided on the tongue patch. The back patch is formed integrally with the tongue patch and is heat-melted and bonded to the base layer.

[0009] A further improvement is that the width of the first reinforcement track heat-melt line is not less than the width of the first heat-melt line.

[0010] A further improvement is that the width of the second reinforcement track heat-melt line is not less than the width of the second heat-melt line.

[0011] A further improvement is that the rear patch is fully arranged on the rear side of the base layer or partially arranged on the rear side of the base layer.

[0012] A further improvement is that the rear patch is partially laid on the rear side of the base layer in an X shape, and one end of the four ends of the X shape is integrally connected to the tongue patch.

[0013] A further improvement is that the edges of both sides of the tongue patch do not exceed the first reinforcement track heat-melting line, and form a second breathable portion with the first reinforcement track heat-melting line.

[0014] By adopting the above technical solution, the beneficial effects of the utility model are:

[0015] In this case, the TPU upper of the first base layer of the first reinforcement layer, the second reinforcement layer, and the third reinforcement layer is used to strengthen the upper of the base layer to improve the wrapping support strength of the upper. Two first reinforcement track hot melt lines and several first hot melt lines are set on the first reinforcement layer. The first hot melt line is tangent to the first reinforcement track hot melt line to form a first reinforcement part, a first breathable part, and a second reinforcement part with alternating strong and weak support strengths, which improves the wrapping support strength of the upper on both sides and the toe while facilitating the ventilation of the toes. The second reinforcement layer is provided with a second reinforcement track hot melt line and a second hot melt line to strengthen the wrapping support strength of the toe of the base layer. The third reinforcement layer is provided with a tongue patch and a rear patch. The tongue patch limits the deformation of the base layer on both sides of the tongue by veneer, which is convenient for the subsequent adjustment of the wrapping strength of the shoelaces on the instep. The rear patch limits the wrapping support strength of the rear side of the base layer on the ankle to prevent rollover and sprains.

[0016] A further beneficial effect is that the width of the first reinforcing track hot melt line is not less than the width of the first hot melt line, the track of the first reinforcing track hot melt line can be clearly seen, the sense of line design is enhanced, and the track of the first reinforcing track hot melt line can also be highlighted by different color schemes.

[0017] A further beneficial effect is that the width of the second reinforcement track hot melt line is not less than the width of the second hot melt line, the track of the second reinforcement track hot melt line can be clearly seen, the sense of line design is enhanced, and the track of the second reinforcement track hot melt line can also be highlighted by different color schemes.

[0018] A further beneficial effect is that the rear patch is partially laid in an X-shape on the rear side of the base layer, which ensures the wrapping support strength on both sides of the ankle while minimizing the impact on the breathability of the base layer on both sides of the ankle.

[0019] A further beneficial effect is that a second air permeable portion is left between the first reinforcement track hot-melt line and the two sides of the shoe tongue patch, thereby reducing the influence of the reinforcement layers on the air permeability of the base layer.
