Description

Technical Field

[0001] This utility model relates to a shoe sole, specifically an air-cushioned shoe sole structure. Background Technology

[0002] Air-cushioned shoes refer to shoes with an air storage chamber between the upper and lower parts of the sole that can form an air cushion. The air storage chamber, together with the air inlet and air outlet channels on the shoe, form a ventilation device. The air inlet channel is vertically located at the rear of the shoe and connects to the air storage chamber from top to bottom. The air outlet channel is horizontally located on the upper part of the sole and connects to the air storage chamber inside the shoe from top to bottom. It has the characteristics of absorbing the impact force of the ground and reducing the injury to the feet.

[0003] A search revealed Chinese patent CN209547113U, which discloses an air-cushioned shoe sole, including a sole body. The sole body is divided into a heel area, an arch area, a forefoot area, and a toe area. The air cushion layer located in the toe area is a single piece. However, it still has the following drawbacks: existing air-cushioned shoe soles usually use an internal hollow structure for rebound. When performing rapid movements, the rebound rate is prone to be too fast, which reduces foot comfort.

[0004] Most current air-cushioned shoe soles use a one-time inflation structure, where the air pressure inside the air chamber is fixed at the factory and cannot be dynamically adjusted according to the user's actual needs. While this design can improve comfort to some extent, the lack of adjustable air pressure makes it difficult to meet the needs of different usage scenarios, such as the varying support requirements of sports, leisure, or rehabilitation. Furthermore, the shape and height of existing air cushion structures are usually fixed, lacking flexibility and thus limiting their ability to adapt to different foot shapes and pressure distributions. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an air-cushioned sole structure that can adjust the airbag pressure to improve comfort and adaptability.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An air-cushioned shoe sole structure includes a sole body, the sole body having a forefoot area, a midfoot area and a heel area, each of the forefoot area, midfoot area and heel area having a plurality of air bladders, the sole body having an air cavity, the air cavity being connected to each air bladder, the sidewall of the sole body having an air nozzle connected to the air cavity, and the sidewall of the air bladder having at least one pleated portion, the pleated portion expanding or retracting according to the inflation volume of the air bladder.

[0008] As a further improvement, the airbag and the sole body are integrally molded.

[0009] As a further improvement, the airbag has a circular or near-circular hollow structure.

[0010] As a further improvement, the aforementioned airbags are arranged in a row on the main body of the sole.

[0011] As a further improvement, the airbag distribution density in the forefoot and midfoot regions is greater than that in the heel region.

[0012] As a further improvement, the air chamber is provided with two chambers, namely a front air chamber and a rear air chamber. The front air chamber is connected to the air bladders in the forefoot and midfoot areas, and the rear air chamber is connected to the air chamber in the heel area. The front and rear air chambers are independent of each other and are not connected. An air nozzle is provided on the side wall of the forefoot area and connected to the front air chamber, and an air nozzle is provided in the heel area and connected to the rear air chamber.

[0013] As a further improvement, the nozzle is equipped with a one-way valve.

[0014] This utility model has the following beneficial technical effects:

[0015] During running, users can adjust the airbag height according to their gait and running intensity to achieve the best cushioning effect. If the user is heavier or needs stronger support, the amount of gas in the airbag can be increased to raise its height, thus providing more stable support. Conversely, if the user prefers a lightweight and soft feel, the amount of gas in the airbag can be reduced to lower its height, creating a more comfortable wearing experience. Furthermore, it is suitable for work environments where prolonged standing or walking is required. Users can adjust the airbag height at any time according to foot fatigue levels to relieve localized pressure and avoid discomfort caused by uneven pressure over a long period.

[0016] In summary, this invention proposes a novel technical solution by incorporating an adjustable air bladder within the sole, thus addressing the technical problem of existing air-cushioned soles' inability to flexibly adjust pressure. The height of the air bladder can be controlled by varying the inflation volume, the design of the pleated areas ensures the air bladder's elasticity, and the zoned adjustment technology achieves differentiated support effects in different areas of the sole. These designs not only enhance the functionality and comfort of the sole but also provide users with a more personalized solution. Attached Figure Description

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection. They can refer to a direct connection or an indirect connection through an intermediate medium, and they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0025] like Figure 1-3As shown, an air-cushioned shoe sole structure includes a sole body 1, which has a forefoot region 2, a midfoot region 3, and a heel region 4. Each of the forefoot region 2, midfoot region 3, and heel region 4 has a plurality of air bladders 5. An air cavity 6 is provided inside the sole body 1, and the air cavity 6 is connected to each air bladder 5. An air nozzle 7 connected to the air cavity 6 is provided on the side wall of the sole body 1. At least one pleated portion 8 is provided on the side wall of the air bladder 5. The pleated portion 8 expands or contracts according to the inflation volume of the air bladder 5, thereby raising or lowering the air bladder 5, changing the height of the protrusion, and adjusting the force support.

[0026] The sole body 1, as the foundation of this invention, conforms to the conventional sole structure. Several airbags 5 are arranged in a matrix, covering the main stress points of the sole, ensuring effective impact mitigation and providing uniform cushioning during walking or exercise. To enhance support, the airbag density in the forefoot and heel areas is significantly higher than in the midfoot area. This design allows for better protection of key stress areas during running or jumping, while reducing fatigue from prolonged use.

[0027] The airbag 5 is a circular or near-circular hollow structure, with pleats 5 evenly distributed along the sidewall of the airbag. It unfolds when inflated, causing the airbag to expand; and folds back when deflated, causing the airbag to contract. This structural design gives the airbag height adjustable, ranging from 2 mm in the fully contracted state to 10 mm in the fully inflated state.

[0028] The specific adjustment process is as follows: S1, the user connects a manual air pump or other inflation tool to the air nozzle and injects gas through the nozzle; S2, the gas enters the air chamber and is evenly distributed to each air bladder; S3, as the gas volume gradually increases, the pressure inside the air bladder rises, the pleats unfold, and the air bladder height gradually increases; S4, when the desired height is reached, the inflation operation stops, and the air bladder maintains its current state. If it is necessary to lower the air bladder height, press the air nozzle to release the gas, and the air bladder will then contract and return to its initial state. An vent button can be provided on the air nozzle for easy operation. The vent button on the air nozzle uses a rotary structure, allowing the user to control the venting rate by rotating the button, thereby achieving fine adjustment of the air bladder height.

[0029] In addition, the inner wall of the air chamber 6 is coated with a smooth coating, which further reduces gas flow resistance and ensures a fast response time for inflation and deflation operations. The outer port of the air nozzle is designed with a standard interface for easy connection to manual air pumps or other inflation tools, while the air nozzle is equipped with a one-way valve to prevent gas leakage from the air chamber when not in use.

[0030] Furthermore, for greater flexibility in adjustment, the air chamber is configured with two chambers: a front air chamber and a rear air chamber. The front air chamber is connected to the air bladders in the forefoot and midfoot areas, while the rear air chamber is connected to the air chamber in the heel area. The front and rear air chambers are independent and not interconnected. An air nozzle is located on the side wall of the forefoot area, connecting to the front air chamber, and another air nozzle is located in the heel area, connecting to the rear air chamber. The air bladder distribution density in the forefoot and midfoot areas is greater than that in the heel area. Both areas can be adjusted independently to meet specific usage needs.

[0031] This zoned adjustment design significantly enhances the functionality and practicality of the sole, allowing users to flexibly adjust the support performance of different areas of the sole according to their actual needs.

[0032] When in use, this invention inflates the air chamber through the air nozzle. Different inflation volumes will cause the airbag to expand by different amounts, thereby utilizing the pleats on the airbag to achieve different extensions and contractions, and thus adjust the height accordingly.

[0033] It should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
