Description

Technical Field

[0001] This utility model belongs to the field of footwear, and more specifically, it relates to a foamed sole weight reduction and cushioning structure. Background Technology

[0002] Foamed soles are lightweight, soft, elastic, and resistant to chemical corrosion. However, they have poor abrasion resistance, so rubber sheets are often bonded to the sole to compensate for this. While rubber sheets are abrasion resistant, they lack elasticity, are heavy, and can negatively impact the comfort of the shoe. Utility Model Content

[0003] In view of the problems in the related technologies, this utility model proposes a foamed shoe sole weight reduction and cushioning structure to overcome the above-mentioned technical problems existing in the existing related technologies.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a foamed shoe sole weight reduction and cushioning structure, including a foamed midsole. A rubber sheet is attached to the bottom surface of the foamed midsole. The bottom surface of the foamed midsole is provided with a groove. The top surface of the rubber sheet is provided with a groove corresponding to the groove. The groove and the groove are closed to form a cavity. An elastic support column is fixedly installed in the cavity.

[0006] Furthermore, the concave texture is provided in multiple ways, and the rubber base is also provided with multiple convex textures, with the multiple concave and convex textures arranged alternately in sequence.

[0007] Furthermore, the groove is provided with multiple support columns, which abut and fit against the corresponding convex patterns, and divide the cavity to form multiple chambers.

[0008] Furthermore, the outer ring of the top surface of the rubber base is provided with annularly distributed raised patterns, and the outer ring of the bottom surface of the foamed insole is provided with an alignment groove that seals and engages with the raised patterns.

[0009] Furthermore, the foamed insole and the rubber backing sheet are sealed and bonded together with adhesive.

[0010] Furthermore, the elastic support column includes a lower support column and an upper support column. The lower support column is fixedly installed in the convex groove, and the top end of the lower support column is provided with a telescopic groove. The upper support column is fixedly installed in the groove, and the bottom end of the upper support column is slidably inserted into the telescopic groove. A spring is installed at the lower end of the telescopic groove to abut against and support the bottom end of the upper support column.

[0011] This utility model has the following beneficial effects:

[0012] 1. In this utility model, the top surface of the rubber sole is provided with concave texture. The concave texture design can reduce the weight of the sole as much as possible. The bottom of the foam midsole has a groove that matches the concave texture of the rubber sole. When the rubber sole is attached to the bottom surface of the foam midsole, the concave part of the rubber sole and the groove part of the foam midsole correspond to form a cavity, which is equivalent to implanting an airbag device in the sole. It forms a cushion when walking, thereby improving the comfort of wearing the shoe. Furthermore, an elastic support column is installed in the cavity. The elastic support column can provide auxiliary support to the cavity, improve the stability of the sole support, and prevent the cavity from bursting or leaking air under the action of air pressure due to excessive force when walking.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0022] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0023] Please see Figures 1-5 As shown, this utility model is a foamed shoe sole weight reduction and cushioning structure, including a foamed midsole 1, a rubber sole 2 attached to the bottom surface of the foamed midsole 1, a groove 1.1 provided on the bottom surface of the foamed midsole 1, and a groove 2.1 corresponding to the groove 1.1 provided on the top surface of the rubber sole 2. The groove 1.1 and the groove 2.1 are closed to form a cavity 3, and an elastic support column 4 is fixedly installed in the cavity 3.

[0024] When the foam sole with this weight-reducing and cushioning structure is applied to a shoe, the top surface of the rubber sole 2 is provided with grooves 2.1, which can reduce the weight of the rubber sole 2, thereby reducing the overall weight of the shoe. At the same time, the cavity 3 can provide air pressure shock absorption during walking, thereby improving the comfort of wearing the shoe. Furthermore, the elastic support column 4 can provide auxiliary support for the cavity 3, improve the stability of the sole support, and prevent the cavity 3 from bursting or leaking air under the action of air pressure due to excessive force when walking.

[0025] Specifically, multiple concave textures 2.1 are provided, and multiple convex textures 2.2 are also provided on the rubber base 2. The multiple concave textures 2.1 and convex textures 2.2 are arranged alternately in sequence. Multiple support columns 1.2 are provided in the groove 1.1. The support columns 1.2 abut against and fit with the corresponding convex textures 2.2, and divide the cavity 3 into multiple chambers.

[0026] Among them, the raised texture 2.2 and the support column 1.2 can support the cavity 3, improve the stability of the sole, prevent large-area deformation of the sole when walking under pressure, and improve the comfort of wearing the shoe.

[0027] Specifically, the outer ring of the top surface of the rubber base 2 is provided with annularly distributed raised textures 2.2, and the outer ring of the bottom surface of the foamed insole 1 is provided with an alignment groove 1.3 that seals and engages with the raised textures 2.2. The outer ring of the cavity 3 is sealed and engaged with the alignment groove 1.3 through the raised textures 2.2, which can improve the sealing performance of the cavity 3 and prevent air leakage from the cavity 3.

[0028] Specifically, the foamed insole 1 and the rubber sheet 2 are sealed and bonded together with adhesive. The adhesive has good sealing performance, and bonding the foamed insole 1 and the rubber sheet 2 together with adhesive can further improve the sealing performance of the cavity 3.

[0029] Specifically, the elastic support column 4 includes a lower support column 4.1 and an upper support column 4.4. The lower support column 4.1 is fixedly installed in the convex groove 2.2, and the top of the lower support column 4.1 is provided with a telescopic groove 4.2. The upper support column 4.4 is fixedly installed in the groove 1.1, and the bottom end of the upper support column 4.4 is slidably inserted into the telescopic groove 4.2. The lower end of the telescopic groove 4.2 is equipped with a spring 4.3 that abuts against and supports the bottom end of the upper support column 4.4.

[0030] When the cavity 3 is compressed and contracts during walking, the upper support 4.4 slides and contracts into the telescopic groove 4.2, and compresses and contracts the spring 4.3. Thus, the elastic force of the spring 4.3 restores and supports the sole, preventing the cavity 3 from over-contracting and increasing the air pressure, which could cause the cavity 3 to burst or leak air. This improves the comfort and lifespan of the shoe.
