With these updates, shoes can continue to improve in functions such as lightweight, support, cushioning, aesthetics, anti-skid and so on.

In order to allow the shoes to keep the user's feet dry in various climates or environments, there are now shoes made of waterproof materials. However, in order to prevent water from the outside from penetrating the shoe, the breathability of the waterproof material will be relatively reduced. After wearing for a long time, the user will feel sultry and unbearable, and after a day of wearing, the inside of the shoe will also generate a foul smell due to sweat and other stains. Relatively speaking, although breathable shoes can avoid the above situation through the circulation of air, the waterproof function will be relatively reduced. Therefore, how to make a waterproof and breathable fabric and shoes is one of the main topics of current development.

The invention provides a breathable cloth which can guide the liquid from the outside to flow on the surface, prevent liquid from penetrating the breathable cloth, and at the same time can provide the function of breathing.

The shoes proposed by the present invention can be applied to, for example, sports shoes, running shoes, sneakers, or casual shoes. Those with ordinary knowledge in the art can be applied to the above or other shoes, and the present invention is not limited thereto.

FIG. 1 is a schematic diagram of a shoe according to a first embodiment of the present invention and a partially enlarged schematic diagram of a shoe upper. Referring to FIG. 1, the shoe 100 of this embodiment includes a sole 110 and an upper 120. The sole 110 is made of rubber or ethylene vinyl acetate copolymer (EVA) or thermoplastic polyurethanes (TPU), etc. The polymer material is formed, and the invention is not limited to the material of the sole 110.

The upper 120 connected to the sole 110 includes a breathable fabric 130. Specifically, the fabric of the upper 120 of the shoe 100 of this embodiment uses the breathable fabric 130, and the distribution area of the breathable fabric 130 may be distributed on part or all of the upper, and the invention is not limited thereto.

Please refer to the enlarged schematic view of the upper in the reference area A in FIG. 1, the breathable fabric 130 includes a breathable braided layer 131 and a plurality of braided scales 132. Here, the braided scales 132 of a partial area are omitted at the lower edge to describe the breathability of this embodiment in detail The relative relationship between the breathable braided layer 131 and the braided scales 132 in the fabric 130 is not intended to limit the relative positional relationship of the elements of the present invention. The breathable braided layer 131 connects the braided scales 132, and the connection between the breathable braided layer 131 and the braided scales 132 can be completed, for example, by stitching or braiding, and the present invention is not limited to the connection.

In the breathable braided layer 131 of this embodiment, these braided scales 132 are arranged in multiple Scales. Taking the scale strips 132R1 and the scale strips 132R2 as an example, the scale strips 132R1 and the scale strips 132R2 are arranged along the first direction d1, and the woven scales 132 in the scale strips 132R1 and 132R2 also extend toward the first direction d1. The extension direction of each end of each woven scale 132 connecting the air-permeable woven layer 131 is substantially parallel to the first direction d1, and each woven scale 132d may overlap the other woven scales toward the first direction d1. Taking FIG. 1 as an example, the first direction d1 is, for example, a direction toward the sole 110, and the woven scales 132 may extend toward the sole 110, for example.

The scale strips 132R1 and the adjacent scale strips 132R2 of this embodiment are arranged along the second direction d2 in a staggered manner. The distribution area of the scale strips 132R1 in the breathable fabric 130 and the scale strips 132R2 are partly distributed in the distribution area of the breathable fabric 130 They overlap so that a gap can be formed between the scale strip 132R1 and the scale strip 132R2 to allow the gas G to circulate.

For example, woven scales 132A in FIG. 1 are stacked on woven scales 132B, 132C and woven scales 132D. Since the side edges of the braided scales 132B and the braided scales 132C are stacked between the braided scales 132A and 132D, an area is formed between the braided scales 132A and 132D to allow air to flow out of the breathable braided layer 131.

At the same time, the braided scales 132 covering the breathable braided layer 131 can prevent external liquid from directly contacting the breathable braided layer 131, and the trailing edge of the braided scales 132 can also guide the liquid to flow on the surface. For example, with the shape of these woven scales 132, the liquid LQ1 can successively flow down along the woven scales 132 stacked on top of each other. In other words, the woven scales 132 of this embodiment are arranged in the breathable fabric 130 in a fish scale-like manner, so gaps can be formed between the woven scales 132, and the shape of the woven scales 132 can guide liquid to the insole to the ground , To further prevent liquid from staying on the breathable fabric 130, providing both breathable and waterproof functions.

The above staggered arrangement will be further described in detail below, please refer to FIG. 1, taking scale strips 132R1, 132R2 as an example, the woven scales 132 in scale strips 132R1 of this embodiment are arranged along the alignment line L1, and scale strips 132R2 These woven scales 132 are arranged along an arrangement straight line L2, and the arrangement straight lines L1 and L2 are parallel to the direction d1, and the width W1 in the direction d2 between these straight lines L1 and L2 is smaller than the scales of the woven scales 132 in the direction d2 width. Therefore, each woven scale 132 overlaps the distribution area of other woven scales 132 on the left and right sides of the distribution area of the breathable fabric 130.

On the other hand, these woven scales 132 are also substantially arranged along a plurality of arrangement horizontal lines parallel to the second direction d2. Referring to FIG. 1, taking the arrangement of horizontal lines L3 and L4 as an example, the woven scales 132 arranged along the arrangement of horizontal lines L3 are substantially connected to the breathable braid 131 at the same height in the first direction d1, and adjacent The braided scales 132 on the aligned horizontal line L4 and the braided scales 132 on the aligned horizontal line L3 are also staggered. At the same time, the arrangement horizontal line L3 and the arrangement horizontal line L4 have a height H1 in the direction d1, and the height H1 is less than the length of the scales of the woven scales 132 in the direction d1, so each woven scale 132 is above and below the distribution area of the breathable fabric 130 The side will overlap with the distribution area of other woven scales 132.

With the above arrangement, the woven scales 132 overlapping each other can form a gap to allow air to directly flow out through the breathable woven layer 131, and at the same time, the overlapping woven scales 132 prevent liquid from seeping in.

The braided scales 132 of this embodiment are, for example, woven from waterproof yarn, and the material of the waterproof yarn includes, for example, a polymer material, or may be formed by a woven fabric coated with a waterproof material. With the waterproof properties of the material, the woven scales 132 can further prevent liquid penetration.

On the other hand, the breathable fabric 130 proposed by the present invention can control the waterproof and breathable characteristics by the density of the weave. For example, in the breathable fabric 130, the weave density of the woven scales 132 may be greater than the weave density of the breathable woven layer 131, and the pores of the breathable woven layer 131 may be larger than the pores of the woven scales 132, so gas can easily pass through the breathable woven Layer 131, and the woven scales 132 can block liquid.

The woven scales proposed by the present invention are not limited to the above-mentioned woven scales 132 formed into a semicircular shape, and in other embodiments, other shapes may be formed to guide the liquid. Please refer to FIG. 2. In another embodiment of the present invention, the breathable fabric 230 includes a breathable braided layer 231 and a plurality of braided scales 232 connected to the breathable braided layer 231. The braided scales 232 are formed in a semi-elliptical shape, that is, compared to the braided scales 132 described above, the end edges of the braided scales 232 extend along the direction d1. By increasing the length of these woven scales 232, a larger gap can be formed between the woven scales 232 to allow gas to flow out from the breathable braided layer 231.

Referring to FIG. 3, in yet another embodiment of the present invention, the breathable fabric 330 includes a breathable braided layer 331 and a plurality of braided scales 332 connected to the breathable braided layer 331. The braided scales 332 are formed into triangles extending along the direction d1, so that the trailing edges of the braided scales 332 are substantially parallel to each other, and the liquid W2 can also flow down along the trailing edges in sequence. When the breathable fabric 330 of the present embodiment is applied to the upper, the liquid LQ2 falling on the upper can flow on the surface by the inertia of the user when walking and the shape of these woven scales 332.

In summary, the breathable fabric proposed by the present invention has a plurality of woven scales overlapping each other, and these woven scales are connected to the breathable woven layer. Therefore, while these woven scales cover the breathable woven layer to provide a waterproof function, gaps can also be formed between the woven scales for gas to pass through. The upper of the shoe proposed by the present invention includes breathable fabric, and the breathable fabric is made of breathable fabric. A woven layer and a plurality of woven scales overlapping each other are formed. The gas inside the shoe can flow out through the air-permeable braid and the gaps between the braided scales, and the liquid from the outside of the shoe can be guided by the braided braided scales connected to the breathable braid to flow to the sole to the ground. Therefore, the shoe proposed by the present invention can have both breathable and waterproof effects.
