Abstract

Usage: in the shoe industry in the manufacture of anti-scuff agents. SUMMARY OF THE INVENTION: The removable platform is made in the form of a sole of a shoe made of cold-resistant rubber with a means of attachment on the shoe. On the outer surface of the platform, autonomous vacuum suckers are integrally formed with it. A rim is formed around the entire perimeter of the outer surface. The tabs are placed on the centerline of the outer surface flush with the rim. 3 il.

Description

This invention relates to safety when moving people during icy conditions. The existing structures of anti-slip devices are various types of metal plates and spikes attached temporarily or permanently to the shoe.

The most common and simple method of anti-slip devices are protectors of various shapes applied to the soles of shoes, including those equipped with vacuum suction cups (US Pat. N 2004731 A, 1979).

The proposed construction of a removable anti-skid device in the form of a galoshe worn on shoes has a sole consisting of two layers, between which a groove is formed: an inner flexible one on which cylindrical struts are arranged, and an outer one, on the surface of which are cup-shaped suction cups with a hole connecting the vacuum suction cavities with the internal groove. The suction cup is activated when the opening is closed by the action of the legs and the weight of the person. The main disadvantages of the proposed design are:

all suckers, located both on the outsole and on the heel, are interconnected by an air cavity and therefore they must work simultaneously; when the openings of one or several suction cups are not tightly closed, the force of adhesion to the surface decreases sharply;

making the sole of two layers, of a complex configuration, followed by gluing, is a difficult and time-consuming operation, especially in the manufacture of molds;

the open position of the suction cups on the outer surface of the sole will lead to rapid wear and tear, and flattening, especially at low temperatures due to a decrease in the elasticity of the rubber;

The proposed single layer PSD with vacuum suction cups (platform) L by re-opening the openings of the bare foot is unacceptable for use in the ZiN conditions.

The purpose of the invention is to increase the safety of people when walking with ice and reducing injuries and injuries.

The design of the sole of the footwear (pas. Veli kobritaniiB443731) provides for its use as a sports shoe for games.

SUMMARY OF THE INVENTION: Use an effective vacuum suction cup to increase the footwear (platform) with a slippery surface (ice, ice) in the winter time to increase the safety of people when walking.

To achieve these goals, simplify the design and reduce the cost of cases and / and increase the reliability and reliability of the proposed platform with fastening to the shoes, L cc: l o, and p (, ih- i T OJJI chak1, I wcoc V iH -11 m) f „, G i KL

The horizontal shape contains the sole 1, corresponding to the size of the Omx / o size of the body, made in a single unit with vacuum suction cups of a round shape 2. The lower annular surface of the suction cups is broadened for more contact with the ice surface.

At the top, the lrisosque has the shape of a diaphragm | 1, with wrist mounting

which e is full tide. To limit the amount of deformation, a rim 3 is made around the perimeter of the sole, on the heel 4, the toe 5 and from the center 6 there are continuous tides,

Two metal plates 7 and 8 with eyelets for attaching the platform with straps 9 and 10 to the shoe are fastened on top of the sole.

An insole 11 of finely porous rubber with a surface sphc with another layer is glued to the sole from above.

The marking is applied according to the size of the shoe.

Pagform vacuum works as follows.

When walking on a shoe, the platform initially comes into contact with the surface of the Led part -o or fully g, g with ko-kami, when the walls of the suction cups are compressed by the value of h - differences in the height of the suction cups and limiting borgi etc. among the stops.

Almost simultaneously, ru j destructively of the weight of a person, through the seam o6ven, the compression of the porous grain base is going on and, at the same time, it is amplified and transferred to the sigma-pa-uum-primer, when air is sucked into the suction cups it reduces rf in YULGORCH
