Description

The utility model relates to anti-slip products and can be used in the manufacture of shoes, slippers for shoes for walking in icy conditions and other anti-slip devices, and it can also be used in the manufacture of winter tires and tires.

In the prior art, a spike for preventing slipping is known RU 161112 U1, 04/10/2016, the casing of which has a flat and upper cone made at right angles to the middle in the form of a cone with a protrusion on the top of the part, which allows it to be thus securely fixed to the sole or overlay for shoes. The conical part with a protrusion allows the spike to work effectively not only on ice, but also on a snowy surface. This solution is selected as a prototype.

However, this device is not effective enough, since the protrusion and cone of the tenon in contact with a solid surface will soon grind and wear off, which leads to slipping of the studs on an icy surface. Reducing the dimensions of the spike, increasing the angle of the cone of the upper part, reducing the thickness of the protrusion, i.e. their sharpening leads to even faster wear of the product, so it is necessary to use fairly large spikes, which reduces the usability.

The problem to which the proposed utility model is directed is to significantly increase the efficiency of anti-skid, increase the product life and achieve greater convenience in its operation.

The technical result consists in improving adhesion to a snowy and icy surface by eliminating the possibility of abrasion during operation and reducing stud wear.

This result is achieved by the fact that in the spike to prevent sliding, having a lower flat part and an upper part made at right angles to the middle part, made in the form of a cone for engaging with a snowy and icy surface with a protrusion at the top, the protrusion is an insert made of hard alloy .

In one embodiment, the implementation of the upper cone-shaped part has an angle of 38-40 degrees.

In another embodiment, the insert may have a tapered end.

The presence of a carbide insert eliminates the possibility of its erasure during operation and reduces the rate of wear of the spike. Due to this, the protruding part of such an insert can be made of small dimensions, and can also have a cone-shaped pointed appearance, which will significantly increase the anti-slip effect and, in the aggregate, will achieve maximum adhesion to the surface.

The execution of the upper and lower parts of the tenon at a right angle directly to it to the middle part, in other words, the surface, virtually eliminates the possibility of such a tenon falling out during operation.

The conical shape of the upper part with an angle of 38-40 degrees also increases the effectiveness of the spike on a snowy surface.

Thus, the proposed device can improve the effectiveness of anti-skid on a snowy and icy surface due to better grip.

The utility model is illustrated in figures 1-4.

Figure 1 shows a cross section of a tenon to prevent slipping.

Figure 2 presents a cross section of the present spike with an insert with a conical end.

Figure 3 shows a drawing of a stud to prevent slipping.

Figure 4 shows a drawing of the proposed solution with an insert with a conical end.

The anti-slip spike has an upper part in the form of a cone 1 and a lower flat part 2, which are made - i.e. pass into the middle part - at a right angle (Fig.1-4), which allows you to securely fix this spike in the sole of the shoe or a special pad. The middle part may be of any shape, but Figs. 1-4 are shown cylindrical. The upper part 1 is conical, and it is desirable to produce a cone with an angle of 38-40 degrees. The lower part can be in the form of a round plate, a thin washer or any other flat shape, with a thickness of not more than 2.5 mm. All parts of this spike can be made as a single body of steel, aluminum, plastic, ceramics or other material.

The spike also has an insert 3 protruding from the center of the upper part 1 — the top of the cone — from a hard alloy, such as an alloy of tungsten carbide with cobalt or grades of high hardness steel, hardened steel, or other similar materials. The insert 3 may have a conical or pointed end (Fig.2, 4).

The proposed technical solution works as follows.

This spike as a part of the sole of shoes or ice drifts - special overlays for shoes, as well as tires, effectively interlocks with the protruding insert 3 and the conical upper part 1 with the icy and snowy surface of the road and prevents slipping. The insert significantly increases the resistance of the stud to abrasion and increases the service life of the product, due to which it is possible to reduce the dimensions and vary the shape of both the insert and the stud, including completing the end of the insert with a tapered, pointed for better grip.

Thus, the set of essential features of the tenon to prevent slipping allows you to increase the effectiveness of anti-skid on a snowy and icy surface due to better adhesion.
