Embodiment 1

[0057] The present invention relates to a one-size-fits-all elastic shoe cover 10 . Further, the one-size elastic shoe cover 10 includes a one-size elastic shoe cover upper surface 1 with differentially distributed positive pressure, a shoe sole 3 that can be stretched horizontally and vertically, and a surrounding bar 2 that acts as a clamp. The one-size elastic shoe cover provided by the present invention is a one-size elastic shoe cover 10 with differentially distributed positive pressure, superior protection performance, high comfort and wide applicable size variation. It can perform three-dimensional adaptive wrapping according to the size change of the wearer's shoes. It is suitable for a wide range of shoes, flexible application, wear-resistant and practical, and high comfort. It will be appreciated by those skilled in the art that the present invention has particular application to shoes, but may also be used for other applications such as, but not limited to, dust pro...

Embodiment 2

[0063] Integrated injection molding of the apron sole.

[0064] With the one-yard elastic shoe cover 10 produced by the cold-glue gluing process, the problem of degumming and water leakage often plagues the user. In order to solve such problems, the process is further improved as follows: the integrated injection molding of the apron and the sole.

[0065] like Figure 5-10 As shown, the integrated design of the apron sole is injection molded through a mould. As is well known to those skilled in the art: elastic bands of the same material are loaded with the same elongation load, and when the cross-sectional area is different, the degree of deformation produced is different; the elastic band with a smaller cross-sectional area is stretched longer. Utilize this principle to design the one-size-fits-all elastic shoe cover 10, and achieve the effects of stretching, tightening and protection by adjusting the wall thickness in different regions. like Figure 5 As shown, located...

Embodiment 3

[0068] One-piece overmolding of the apron sole

[0069] It is difficult for one material to take into account all superior mechanical properties. Therefore, the apron and sole of the one-size elastic shoe cover 10 are further improved, and the apron and sole are integrated by a secondary molding process.

[0070] like Figure 11-17 As shown, the integrated sole of the bar is composed of a low modulus elastic soft body 4 and a high modulus protective hard body 5, and is formed by secondary injection molding. The one-size-fits-all elastic shoe cover 10 is made by welding the upper surface 1 of the shoe cover to the connection area between the outer edge of the shoe sole and the lower edge of the shoe cover through a welding process after the secondary molding is adopted for the integral type of the bar and sole. The one-yard elastic shoe cover 10 produced by this process has significantly improved wear resistance and anti-slip, elastic stretching and pressure-sensitive comfort....

Abstract

The invention provides an one-size elastic shoe cover 10, wherein positive pressure is distributed in a differentiated mode under the load state of the upper face, and the one-size elastic shoe cover 10 is excellent in protection performance, high in comfort degree and wide in applicable size change. The shoe cover comprises a sole 3, a shoe cover upper 1 and a foxing strip 2, and is characterized in that the foxing strip 2 is arranged on the outer edge of the sole, and the perimeter of the non-connecting edge 22 of the foxing strip is not larger than the perimeter of the outer edge 32 of the sole and is used for hooping the shoe cover; when the load of the one-size elastic shoe cover 10 is 120%, the fixed elongation load of the sole 3 in the shoe length direction is not greater than the fixed elongation load of the foxing strip 2 in the shoe length direction; and when the shoe cover upper surface 1 directionally extends to 200% of the original length, the fixed extension load of the shoe cover upper surface 1 is less than 50N. Three-dimensional adaptive wrapping can be carried out according to the size change of shoes of a wearer, and the shoes are wide in size range, high in flexible applicability, resistant to abrasion, practical and high in comfort level.

Description

technical field [0001] The invention relates to a jacket-type shoe protection device, and more particularly, to a one-yard elastic shoe cover used to protect shoes from being soaked by rainwater, dust and stains. Background technique [0002] There are many kinds of jacket-type shoe protection devices, such as non-woven shoe covers for dust protection, rubber shoe covers for anti-skid use on snow, rain-proof shoe covers for preventing shoes from getting wet in rainy days, and so on. [0003] At present, there are two types of rain shoe covers on the market. One is a structural rain shoe cover composed of independent soles and uppers. It has a fixed size specification and is only suitable for people with shoes of the same size. If the size does not match, it is extremely uncomfortable to wear, and even causes the shoe cover to be broken, and the flexibility is not strong; It can adapt to the size change from small to large in a small range, but this type of product still has...
