Description

Technical Field

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

[0002] The sole is mainly used to support the sole of the foot and improve wearing comfort. In order to improve the shock absorption effect of the sole, more and more shoes will be equipped with air cushions between the insole and the outsole. Traditional air cushions have regular structures such as rectangles and cylinders, which are not conducive to the installation and positioning of the air cushion in the sole. As a result, the air cushion will be offset and misplaced after installation, affecting the shock absorption effect of the air cushion itself. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the technical solution adopted by the present invention is: a lightweight air-cushioned sole, including an insole, an outsole wrapped around the bottom of the insole, and an air cushion arranged between the insole and the outsole, the air cushion being provided with an outer annular portion and a cylindrical portion, the outer annular portion being provided at the outer edge of the air cushion, the cylindrical portion being provided on the upper surface of the air cushion, the insole and the outsole being combined to form an installation groove for installing the air cushion, and the insole being provided with a shock-absorbing column for accommodating the cylindrical portion.

[0004] By adopting the above technical solution, the shock absorption effect of the shoe is improved by adding an air cushion at the heel position, wherein the outer ring part is used to support and buffer the downward force from all sides of the heel, thereby protecting the ankle. The air cushion supports and buffers the vertical force from the insole of the shoe, and increases the vertical deformation of the air cushion through the cylindrical part. The cylindrical part also plays a positioning role between the insole of the shoe, preventing the air cushion and the sole from being misaligned, so as to maintain the shock absorption effect of the air cushion structure.

[0005] The present invention is further configured such that a support net distributed in a cross shape is provided on the inner side of the insole, and the shock-absorbing columns are distributed in an array at the intersections of the support nets.

[0006] Furthermore, an inner hole is provided at the bottom of the shock-absorbing column, and the cylindrical portion is snap-connected to the inner hole.

[0007] Using the above technical solution, the support net is composed of a combination of reinforcing ribs distributed in a cross shape, which is used to improve the structural strength of the insole of the shoe. The shock-absorbing column is located at the intersection of the reinforcing ribs to improve the support effect at the heel. The distributed support net curve fits the curve of the human arch, increasing the elasticity and comfort of the sole and making the overall weight of the sole lighter.

[0008] The utility model is further configured such that a convex portion is provided on the lower surface of the air cushion, and the air cushion is clamped to the outsole of the shoe through the convex portion.

[0009] By adopting the above technical solution, the raised portion increases the thickness of the air cushion and plays a positioning role between the air cushion and the shoe outsole, thereby preventing misalignment between the air cushion and the shoe body.

[0010] The present invention is further configured such that the outer annular portion is overall U-shaped and distributed at the outer edge of the air cushion, and the thickness of the outer annular portion is greater than the thickness of the raised portion.

[0011] By adopting the above technical solution, since the thickness of the outer ring portion is greater than the thickness of the air cushion, the air cushion as a whole has a structure that is higher on the outside and lower on the inside, effectively supporting and protecting the ankle.

[0012] The present invention is further configured such that an inner groove is provided on the outsole directly below the air cushion, and anti-slip grooves are provided around the outsole located in the inner groove.

[0013] By adopting the above technical solution, when the heel of the outsole of the shoe is deformed, the inner groove provides the space required for deformation, thereby improving the shock absorption effect. The anti-slip pattern increases the friction coefficient between the shoe and the ground, thereby improving the anti-slip effect of the shoe.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The outer ring is used to support and cushion the downward force from around the heel, thereby protecting the ankle;

[0016] 2. The air cushion supports and buffers the vertical force from the insole of the shoe, and increases the vertical deformation of the air cushion through the cylindrical part. At the same time, the cylindrical part plays a positioning role between the insole of the shoe, preventing the air cushion and the sole from being misaligned, so as to maintain the shock-absorbing effect of the air cushion structure.

[0017] The embodiments of the present invention will be further described below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-3As shown, this embodiment provides a lightweight air cushion sole, including an insole 1, an outsole 2 wrapped around the bottom of the insole 1, and an air cushion 3 arranged between the insole 1 and the outsole 2, the air cushion 3 is provided with an outer annular portion 31 and a cylindrical portion 32, the outer annular portion 31 is provided at the outer edge of the air cushion 3, and the cylindrical portion 32 is provided on the upper surface of the air cushion 3, the insole 1 and the outsole 2 are combined to form a mounting groove 11 for installing the air cushion 3, the insole 1 is provided with a shock-absorbing column 12 for accommodating the cylindrical portion 32, and the shock-absorbing effect of the shoe is improved by adding the air cushion 3 at the heel position, wherein the outer annular portion 31 is used to support and buffer the downward force from the surrounding areas of the heel, thereby protecting the ankle, the air cushion 3 supports and buffers the force from the vertical direction of the insole 1, and increases the vertical deformation of the air cushion 3 through the cylindrical portion 32, and the cylindrical portion 32 also plays a positioning role between the insole 1 to prevent the air cushion 3 from being dislocated during installation.

[0024] In this embodiment, a support mesh 13 distributed in a cross pattern is provided on the inner side of the insole 1, and shock-absorbing columns 12 are distributed in an array at the intersection of the support mesh 13. An inner hole 14 is provided at the bottom of the shock-absorbing column 12, and the cylindrical portion 32 is clamped in the inner hole 14. The support mesh 13 is composed of reinforcing ribs distributed in a cross pattern, which is used to improve the structural strength of the insole 1. The shock-absorbing column 12 is located at the intersection of the reinforcing ribs to improve the support effect at the heel, and the distributed support mesh 13 curve fits the arch of the human foot, increases the elasticity and comfort of the sole, and makes the overall weight of the sole lighter.

[0025] In this embodiment, a raised portion 33 is provided on the lower surface of the air cushion 3, and the air cushion 3 is clamped to the outsole 2 through the raised portion 33.
