The present invention relates to anti-skid tread for shoes.

The present invention also relates to a method of obtaining mentioned anti-slip tread.

As you know, there are many situations when you need to walk, run or work in/on the ground (ground or surface), which became slippery due to rain, dirt, snow or ice, or to get over the ground in the direction of dry soil, covered with degaetano and asphalt, and then back on a very slippery surface.

These conditions ground conditions can harm the feet of the athlete, mountaineer, hiker or anyone who works in these conditions every day.

Currently, there are a variety of types of footwear with soles with anti-slip tread for Hiking long distances (tracking), walks and for security purposes.

It is also known that there are soles, components directly protector, however, there are also soles, which, being made of unstable abrasion material, have protector applied on the lower part and is made of a different material that is more resistant to wear and efforts that are created due to the forces arising in the process of walking or running.

While protective shoes with slip resistant properties usually Bo is esiste cases simply provided with a sole with tread, made in a special way in the form of recesses, grooves and the like, trekking (Hiking) boots, additionally, the possibility of fixing cats (spikes) to the sole.

Normal or climbing boots with cats that can vytaskivatelya (eject) from the sole or zataskivatj (vdvinut'sā) to it, depending on whether the user is walking on ice or ice surface, also known.

Mentioned dragged cats cover one or two of the limited area of the sole and, thus, provide traction only when at least one of these two sites, usually the toe or heel (heel), pressed to the ground; in addition, for the extension and movement of cats back it is necessary to act manually on the appropriate mechanism, which is provided with a sole, interrupting walking and bending for carrying out manipulations with shoes on his feet.

In addition, the user of such footwear having a sole with a retractable cats need time to understand what he's going to go on the ice-covered area and has to act quickly for the nomination of thorns, otherwise you risk to fall is the same as in the case of a pair of ordinary shoes.

Also known spikes clutch that can be attached to any tread made of rubber is wow or plastic material, any type of footwear, and mentioned the spikes can be a simple way removed from the mounting slots, which are obtained by twisting it into the protector, and later re-installed.

Although this type of studs and provides a great grip on ice and rock, it requires considerable time to install and remove, and therefore the shoes are prepared for ice or in whole, slippery surfaces, it is very inconvenient to use on a normal surface.

In addition, the screwing mentioned very solid studs in the tread causes, in the case of excessive force, divide and cut the soles in place of the twisted plot of the spike so that the spike is bad and does not work properly, and, moreover, bends and tends to fall out of the nest, which has just been formed by the thread protector.

In a similar way as was described for Shoe soles, the tyre tread, even if they have grooves and regulated from the point of view of temperature, are well suited to work with the ice surface only with chains or spikes.

Studded wheels very inconvenient because they must be installed as a replacement for conventional wheels with normal protector, which just made grooves, whereas it is known that snow chains are very inconvenient from the point of view of installation is, in addition to the fact that not all machines with a large volume of the cylinder can be supplied with such circuits against snow due to the proximity of the wheel to the wheel arch, which protects him.

Snow proof "socks"made from anti-slip fabric that is put on the wheel, now known as replacement snow proof chains.

Although these "socks" and are more easily compared with chains and equally effective in terms of traction on the ice, they also require the installation operation and withdrawal options in addition to the fact that they occupy a certain place in the trunk of that chain.

The aim of the present invention is to provide an anti-slip tread, capable of eliminating the disadvantages of the known types of protector.

In the framework of this purpose the purpose of this invention is to provide an anti-slip tread, is able to fully perform its function without the need to install studs, cats or any other subsidiary of anti-slip devices.

Another objective of the present invention is to provide an anti-slip tread, which can be embedded in a simple way in various known types of products, such as Shoe soles or shoes, tires, caterpillars and the like.

Under this goal is another object of the invention is to provide a method for obtaining anti-slip tread for the manufacture of soles for shoes, tires, caterpillars and the like, provided with a protector, which eliminates the disadvantages of known types of protectors and appropriate anti-slip devices.

Another object of the present invention is to provide an anti-slip tread, which can be provided to the soles for the shoes or boots of any type and shape, from the usual urban shoes to technical trekking shoes and sports shoes, in General, to secure the Shoe.

Another object of the present invention is to provide a sole with anti-slip tread for the soles, which has technical properties as well as properties related to the comfort, which are not lower than those possessed by the known types of Shoe soles.

Another object of the present invention is to provide an anti-slip tread and method of its manufacture, which can be done by known devices and technologies.

The latter is applied to the basic detail to find outside the periphery of the rotary plate so that the rotary plate is placed between the O-ring and the basic detail. At that the outer surface of the rotary plate is in sliding contact with an adjoining surface of the O-ring, whereby the O-ring prevents the access of dirt or mud inside the module. The module is made with an ability to install in a pre-formed structure of the sole so that the rotary plate is open through a hole in the outer sole of this structure. Use of the pre-assembled module with the rotary plate facilitates its insertion into a shoe using a general technique of mass production of shoes.

EFFECT: simplification of manufacture and insertion of the module of the invention into teva shoes to ensure the sole rotation around the rotary plate when turning or twisting of the user's foot at the moment when the rotary plate is in contact with the ground.
