Description

Technical Field

[0001] The utility model relates to the technical field of soles, in particular to a sole with an air cushion and an insole with an air cushion. Background Art

[0002] During running, every time your foot touches the ground, it will inevitably exert a force of 2-3 times your body weight on the ground. At this time, the ground will generate an equal and opposite force. The most common way of landing for most mass runners is to land on the heel. The moment the heel touches the ground, the ground will directly impact the foot and calf with a reaction force. After the sole of the foot completely lands, the sole and calf will be subjected to the reaction impact force again due to supporting the body weight. If you run on your heels for a long time, it will increase the cushioning force on the knees, hip joints and spine, and may cause periostitis, leg joints and other injuries. Shoes can be used to protect the feet from external stimuli and injuries. The soles and insoles play a role in cushioning and supporting.

[0003] Many shoes with shock-absorbing and rebounding functions on the market are improved in the material or structure of the shoes. Air cushion shock absorption is widely used in the field of sports shoes because of its good compression and rebound performance. However, traditional air cushion soles or traditional air cushion insoles often have a large cavity volume of a single air cushion and poor durability. Once the air cushion cavity is damaged, the shock-absorbing and rebounding function of the shoe will be greatly reduced, and even seriously affect the overall functionality. Therefore, it is still necessary to improve the shoes.

[0004] In view of this, the applicant conducted an in-depth study on the above-mentioned issues, which led to the present case. Utility Model Content

[0005] The utility model aims to provide a shoe sole with an air cushion to improve the durability of the shoe sole.

[0006] The utility model also aims to provide an insole with an air cushion to improve the durability of the insole.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A sole with an air cushion comprises a sole body, on which at least one air cushion is arranged, the air cushion comprises an outer capsule membrane covering an internal cavity and a plurality of inner capsule membranes located in the internal cavity, each of the inner capsule membranes divides the internal cavity into a plurality of mutually independent capsule cavities, and each of the capsule cavities is in the shape of a polygon.

[0009] Preferably, the outer capsule membrane and / or the inner capsule membrane is a TPU film, and the thickness of the TPU film is 0.2-8 mm.

[0010] Preferably, the air cushion further comprises an outer shell covering the outer capsule membrane, and the outer shell is in close contact with the outer capsule membrane.

[0011] Preferably, the shell is a TPU shell.

[0012] Preferably, the air cushion is provided at the sole body at a position relative to the forefoot area of ​​the human foot, at a position relative to the midfoot area of ​​the human foot, or at a position relative to the rearfoot area of ​​the human foot.

[0013] Preferably, the sole body is provided with the air cushion at a position relative to the forefoot area of ​​the human foot, at a position relative to the midfoot area of ​​the human foot and at a position relative to the rearfoot area of ​​the human foot; the maximum air pressure of the bag cavity in the air cushion corresponding to the forefoot area of ​​the human foot is lower than the maximum air pressure of the bag cavity in the air cushion corresponding to the midfoot area of ​​the human foot; the maximum air pressure of the bag cavity in the air cushion corresponding to the forefoot area of ​​the human foot is higher than the maximum air pressure of the bag cavity in the air cushion corresponding to the rearfoot area of ​​the human foot.

[0014] Preferably, the sole body includes an air cushion, and the air cushion is a full-sole air cushion in the shape of a human sole.

[0015] Preferably, a groove is formed on the side of the sole body, and the air cushion is embedded in the sole body or inserted in the groove.

[0016] Preferably, the sole body has a midsole and an insole; the air cushion is sandwiched between the midsole and the insole, or is located on the upper surface of the midsole, or on the lower surface of the midsole, or on the upper surface of the insole, or on the lower surface of the insole.

[0017] A shoe insole with an air cushion comprises an insole body, on which at least one air cushion is arranged, the air cushion comprises an outer capsule membrane covering an internal cavity and a plurality of inner capsule membranes located in the internal cavity, each of the inner capsule membranes divides the internal cavity into a plurality of mutually independent capsule cavities, and each of the capsule cavities is in the shape of a polygon.

[0018] By adopting the above technical solution, the beneficial effects of the utility model are:

[0019] 1. An air cushion is arranged on the sole or insole, and the interior of the air cushion has a plurality of independent cavities. The cavities in the air cushion are formed by dividing the outer cavities by the inner cavities. There is no gap between the cavities, and the size and air pressure of each cavity are relatively independent. If the outer side of the air cushion is damaged, only the cavities corresponding to the damaged part will fail, which has little effect on the overall functionality of the sole or insole. Compared with the traditional air cushion sole or insole, the sole or insole will not cause the failure of the air cushion in a large area due to local damage on the outer side of the air cushion, which will seriously affect the overall functionality. The sole or insole has higher durability and higher shock absorption and rebound performance. Furthermore, the shape and size of the air cushion can be customized according to the concave-convex structure of the shoe (i.e. actual usage) to meet a wider range of needs.

[0020] 2. By providing an outer shell covering the outer capsule membrane, the air cushion is protected, which is beneficial to improving the durability of the air cushion.

[0021] 3. By setting an air cushion inside the sole body, it is helpful to improve the shock absorption and rebound performance of the local area.

[0022] 4. By setting grooves on the side of the sole body and designing the pattern of the grooves, the air cushions are inserted into the grooves, which not only ensures the overall functionality but also provides a design basis for diverse options for the appearance design.

[0023] 5. By setting air cushions with different bladder volumes, different bladder membrane (including outer bladder membrane and inner bladder membrane) thicknesses and different bladder membrane air pressures in the forefoot area, midfoot area and rearfoot area relative to the human foot in the sole body, the different usage needs of the three areas can be met:

[0024] a. The forefoot air cushion is used to support the forefoot area of ​​the sole to meet the needs of major force generation;

[0025] b. The midfoot air cushion is used to support the midfoot area of ​​the sole to meet the needs of support and force conduction;

[0026] c. The heel air cushion is used to support the rear foot area of ​​the sole of the foot to reduce the interaction force between the heel area and the ground after landing and to improve the shock absorption performance. BRIEF DESCRIPTION OF THE DRAWINGS

There is no gap between the cavities 12, and the size and air pressure of each cavity 12 are relatively independent. If the outside of the air cushion 10 is damaged, only the cavities 12 corresponding to the damaged part will fail, which has little impact on the overall functionality of the sole. Compared with traditional air cushions, the failure of a large area of ​​the air cushion 10 due to damage on the outside will not seriously affect the overall functionality, and the durability is higher. Furthermore, whether the air cushion 10 is embedded in the sole body 20 or inserted in the groove opened on the side of the sole body 20, the shape and size of the air cushion 10 can be customized according to the concave-convex structure of the sole (i.e. actual usage) to meet a wider range of needs.
