Description

Technical Field

[0001] This utility model relates to a shoe with adjustable breathability. Background Technology

[0002] In regions with significant seasonal climate changes, people prepare appropriate clothing and shoes based on the season and temperature. For example, in cold winters, warm boots and clothing are chosen, while breathable shoes are preferred in spring and autumn when sweating is more common. However, during seasonal transitions, temperatures often fluctuate rapidly, with significant differences between morning and midday temperatures. In such cases, the aforementioned measures are often insufficient; non-breathable, warm shoes result in stuffy, sweaty conditions at midday, while breathable, cool shoes are too cold in the morning. Chinese utility model patent CN221265361U discloses a breathable, adjustable casual shoe that uses a movable, breathable membrane to alter breathability. However, due to the limited coverage of the movable membrane, the breathable portion of this design is often relatively localized, unlike ordinary breathable shoe uppers which achieve good breathability through a large breathable surface. Utility Model Content

[0003] To address the above shortcomings, the purpose of this utility model is to provide a shoe with adjustable breathability.

[0004] Therefore, this utility model provides a shoe with adjustable breathability, including an upper with a breathable section. The breathable section is located at the forefoot and heel of the shoe, connected by a breathable channel. Each breathable section includes a breathable layer near the shoe cavity. Different breathable layers with shapes matching the breathable section are also included. The breathability of the shoe upper can be adjusted by selectively covering or not covering the breathable layer with a corresponding functional layer.

[0005] Furthermore, the ventilation section of the forefoot is vertically or nearly vertically positioned on the front side of the forefoot, extending from one side of the toe to the other.

[0006] Furthermore, the shoe includes a sole with a forefoot flap that extends above the toe and the foot. The forefoot ventilation section has an overall arc-shaped structure and a recessed portion that mates with the forefoot flap.

[0007] Furthermore, the edges of the breathable portion and the surface layer are provided with mutually cooperating fixing components.

[0008] Furthermore, the surface layer is made of a non-breathable material and has several U-shaped slits. Several protrusions are provided on the breathable part. The protrusions cooperate with the U-shaped slits. When the surface layer covers the breathable part, the protrusions squeeze the U-shaped slits to create a channel between the slits and the surface layer for ventilation.

[0009] Furthermore, the surface layer includes elastic breathable finishing layers on both sides and an impermeable layer in the middle. The impermeable layer includes grooves that correspond to the U-shaped cuts. The protrusions match the grooves. When the surface layer covers the breathable part, when the grooves face the protrusions, the protrusions will not push out the U-shaped cuts. When the U-shaped cuts face the protrusions, the protrusions will push up the U-shaped cuts to form a breathable channel.

[0010] Furthermore, the rear ventilation section is symmetrically arranged along the rear seam line and extends from one side of the rear panel to the other side.

[0011] Furthermore, the upper has several raised strips on the side facing the shoe cavity, the raised strips extending from the rear ventilation part to the front ventilation part, and ventilation channels are formed between adjacent raised strips.

[0012] Furthermore, the inner lining of the side panel is provided with a ventilator extending from the rear side panel ventilator to the front side panel ventilator. The lining is made of a breathable material, and the ventilator is provided with multiple lateral vent holes.

[0013] Furthermore, the vent is located on the upper and / or lower side of the vent pipe.

[0014] The beneficial technical effects of this utility model are as follows:

[0015] This invention relates to an adjustable breathability shoe, which features breathable sections on the upper. These breathable areas are achieved by covering (or not covering) these areas with breathable or non-breathable layers or layers with varying breathability properties. Unlike existing technologies, this invention incorporates breathable sections at the forefoot and heel, connected by breathable channels. This design maximizes breathability during walking. When walking, the shoe travels at a certain speed relative to the outside air. Air flows in through the forefoot breathable section, compressing the air inside the shoe cavity before flowing out through the heel breathable section. During this process, the air in the breathable channels maintains a certain velocity. Areas with higher air velocity generate relatively lower air pressure. In other words, the air inside the shoe cavity flows towards the breathable channels under the pressure difference, thus expelling the air and improving breathability. Attached Figure Description

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] Reference Figures 1 to 6 As shown, this utility model discloses a shoe with adjustable breathability, including an upper with a breathable section. The breathable sections are respectively located on the forefoot and heel of the shoe, and the forefoot breathable section 2 and the heel breathable section 3 are connected by a breathable channel 6. The breathable section includes a breathable layer near the shoe cavity; and surface layers 4 with different breathability properties, having shapes that match the breathable sections. The breathability of the shoe upper can be adjusted by selectively covering or not covering the corresponding surface layers 4 on the breathable layers. In the technical solution of this utility model, walking and running movements give the foot a certain speed (relative to the air), allowing air to enter from the front of the forefoot ventilation section, compressing the gas in the front of the shoe cavity, and flowing along the ventilation channel 6 to the rear ventilation section. The gas flowing in the ventilation channel 6 has a certain flow velocity, and the higher the air velocity, the lower the air pressure, creating a certain pressure difference between the shoe cavity and the ventilation channel 6. This causes gas from other parts to also flow into the ventilation channel 6 and be discharged through the rear ventilation section, thereby improving the overall ventilation and air exhaust effect within the shoe cavity. The main structure of this technical solution includes the forefoot ventilation section 2, the rear ventilation section 3, and the ventilation channel 6, which will be described in detail below.

[0025] Reference Figure 1As shown, the forefoot ventilation section 2 is vertically or nearly vertically positioned on the front side of the forefoot. This placement ensures that air enters almost perpendicular to the direction of foot movement during walking, resulting in better air intake. To increase the windward surface area, the forefoot ventilation section 2 can extend from one side of the toe to the other. The overall shape of the forefoot ventilation section 2 and the outer layer 4 that mates with it is arc-shaped, and the arc-shaped edge 401 can be fitted with fasteners such as Velcro or buckles for secure fastening. In rainy weather, where rainwater can easily enter the ventilation section, the sole of this embodiment can also feature a forefoot flap 1. The forefoot flap 1 curves upwards and extends above the toe and foot, and the forefoot ventilation section 2 has a corresponding recessed portion that mates with the forefoot flap 1.

[0026] The outer layer 4 can be configured in several ways, including using non-breathable fabric, breathable fabric, or outer layers with different breathable materials and structures. By combining outer layers with different breathable functions with the breathable parts, different breathability performances can be achieved. The above method achieves different breathability functions by changing the outer layer 4, but this has certain inconveniences in actual use. Figure 3 and Figure 4 The diagram illustrates a breathable structure where the surface layer 4 is made of a non-breathable material. The surface layer 4 has several U-shaped slits 402 and includes elastic breathable decorative layers 403 on both sides and a non-breathable layer 405 in the middle. This ensures that the surface layer 4 is aesthetically pleasing and coordinated with the side panel regardless of which side faces upward. The non-breathable layer 405 includes grooves 404, which correspond to the positions of the U-shaped slits 402. The U-shaped slits 402 can be created by cutting in the non-breathable layer 405 with a U-shaped tool. Several protrusions are provided on the breathable portion. The protrusions cooperate with the U-shaped slits 402 and the grooves 404, so that when the grooves 404 of the surface layer 4 face the protrusions, the protrusions will not push out the U-shaped slits 402. When the U-shaped slits 402 face the protrusions, the protrusions will push up the U-shaped slits 402 to form a breathable channel. Thus, by fixing the different sides of the surface layer 4 facing the breathable portion, different breathable functions can be achieved.

[0027] Reference Figure 1 and Figure 5 As shown, the ventilation section 3 of the back panel is symmetrically arranged along the back panel seam line (the center line of the back panel) and extends from one side of the back panel to the other side.

[0028] Reference Figure 5As shown, in one embodiment of the ventilation channel 6, the upper has several raised strips 5 on the side facing the shoe cavity. The raised strips 5 can be formed by stacking multiple layers of inner lining fabric 7, by weaving fabric, or by other forms. The raised strips 5 extend from the rear ventilation part 3 to the front ventilation part 2, and ventilation channels 6 are formed between adjacent raised strips 5. In existing shoes, the foot and the shoe cavity fit together, and the foot actually blocks the flow of gas inside the shoe cavity. This is why it is difficult for people to smell odors inside the shoe when wearing shoes, but the odor inside the shoe cavity is easily dispersed into the air after the shoes are taken off. This application, by setting adjacent raised strips 5, the recessed part between adjacent raised strips 5 forms a channel connecting the forefoot and the rear of the shoe on the surface of the inner lining 7 of the upper. This allows the gas to be expelled to the rear of the shoe under the compression of the air intake in the forefoot, and the pressure difference generated by the faster gas flow in the exhaust channel causes the gas in other parts of the shoe cavity to flow to the exhaust channel.

[0029] Reference Figure 6 As shown, in another embodiment of the ventilation channel 6, the inner lining 7 of the upper is made of a breathable material, and a ventilation tube 8 is provided on the inner side of the inner lining 7. The ventilation tube 8 is provided with a plurality of lateral ventilation holes 801. The ventilation tube 8 extends from the rear ventilation part 3 to the front ventilation part 2. In order to avoid the foot squeezing the ventilation holes 801 and affecting the ventilation of the shoe cavity to the ventilation tube 8, the ventilation holes 801 are located on the upper and / or lower side of the ventilation tube 8.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
