Description

Stripe or speckled anti-skid element

The invention relates to a strip or speckle-shaped Anti-skid element according to the preamble of claim 1.

In the most well-known area of application, the surface is any earthly occurrence Surface that has temporarily become slippery due to the weather due to moisture and / or snow and / or ice is, so that, for example, objects such as vehicle wheels can slip and the pedestrian slip can. In all these sliding processes, the one between the object and the one that has become slippery plays a role Surface-transmitted tangential force that is perpendicular to the normal force, a role. If between the If there is sufficient friction between the object and the surface, this tangential force is caused by the Frictional adhesion between the object and the upper

area recorded and transferred, so that for example a driven vehicle wheel can roll and a person can walk. As anti-skid elements are both for Vehicle wheels as well as for footwear facilities known that positively this tangential component from Wheel or transferred from the footwear to this anti-skid element. The anti-skid element itself has a non-slip surface that is adequate with the surface on which the object can slide "Frictional adhesion generated. Studs, prongs, iron tips and the like are known for this non-slip surface. In such anti-skid elements, the anti-skid element must for the most part be the tangential component absorb the acting force through the formation of mechanical stresses and, if necessary, deformations.

A so-called grain ice strip is known from DE-OS 3345979. This ice band has a tough tear and abrasion-resistant plastic tape or hard rubber tape. It forms a hard rubber or plastic jacket with a cast close-meshed steel wire mesh. In the kart rubber or plastic sheaths become sharp-grained, hard Stone, glass or possibly also steel grains in large numbers closely lined up with one another, cast in, which anchor themselves in the steel wire mesh. This grain band is made with the help of lateral Chain hoists similar to snow chains on motor vehicle wheels assembled. In the case of shoe soles, a strip of grain ice tape is placed on the heel and on the tread Self-adhesive strips stuck on. This tape looks like very coarse-grained sandpaper on the outside. With this one known grain ice strip, it is disadvantageous that a chain

which is required. In particular, however, in Schuh- 'i the gluing is very disadvantageous because the glue point is the tangential component of the forces acting have to be transferred and therefore have a great adhesive power which, on the other hand, prevent easy peeling. Entering indoors with a stuck on In many cases, tape that looks like very coarse-grained sandpaper is not possible.

The invention is based on the object of a strip-shaped or patch-shaped anti-skid element that can be manufactured cheaply to create whose production costs are so low that it can be used after a single or very brief use can be thrown away and which is designed so that the main part that is between the object and the anti-skid element acting tangential forces not positively but also through friction can be transferred.

According to the invention, this object is achieved by the technical Teaching of claim 1 solved.

A pinacohedron or sheet-like carrier is provided and not just the surface that is in contact with the surface on which slippage may occur but the other surface that comes into contact with the object to be protected against sliding, has a granular or granular structure. Most of the tangential force between the Object and the anti-skid element is from the one surface of the carrier as a result of its granular or

12Keutz.dez

granular structure added by frictional contact and the same frictional contact takes place between the other surface of the carrier and the surface on which the. The object can slip instead. The attachment of the pinacohedron or sheet-like carrier on the object need essentially only one such Have strength that the anti-skid material is nicb +. can detach from the object or be lost. This connection does not have to absorb essential forces. This anti-skid element thus has a new type spatial configuration through structuring both surfaces, for example, the tangential forces of the object tending to slide in the simplest way transferred from the vehicle wheel or footwear to streets, sidewalks or the like.

With special. Advantageously, granular bodies or granular material can be incorporated into both surfaces of the carrier be. This storage can take place during manufacture if, for example, the carrier consists of a Plastic material is made. But it is also possible according to the invention that the two surfaces of the carrier are coated with the granular bodies and / or the granular material. In particular the granules and / or the granular material on the surfaces of the carrier in a binder layer be embedded.

To simplify production, it is provided that the Carrier consists of two layers that lie against one another with their granulate-free surfaces. Only in each case a surface of one of these layers then has a

granular or granular structure, if necessary. By a corresponding coating, which in certain cases can also be referred to as sanding.

A wide variety of materials are available for the carriers available, and it has proven particularly advantageous that the carrier is made of a material consists, which is selected from the following group: Cellulose-containing material such as cardboard, plastic, such as soft / hard PVC, polyethylene, PU foam, styrofoam, Hardboard, wood, sheet metal, textiles (woven and non-woven).

The granular bodies and / or the granular material can contain metal components or contain metal components are formed. But it is also possible to use these granular bodies or the granular material made of mineral Select components or produce a mixture of metallic and mineral components. In particular, it can be advantageous for the G-j pellets or the granular material to contain silicates. But there is also the possibility that these bodies or this material are made of plastic. A mixture of these materials is also possible.

The granular bodies and / or the granular material can have a different grain size distribution on one surface of the carrier than have on the other surface. This means, inter alia, that on both sides the shares of the different sieve sizes are different. It but it is also possible that the granular or granular structure is more prob-grained on one side than on the other. This means that the maximum

Grain size of the mixture on the one hand has a greater value than on the other hand. . ...,

A particularly advantageous and inexpensive embodiment is created in that the granular body and / or the granular material split, quartz, sand or the like contain. It is particularly advantageous if the carrier is a roofing or tar felt that is simple or can be sanded twice.

For objects of daily use such as, in particular, shoes or equipment, such as, in particular, vehicle wheels, which on Wet and / or ice and / or snow-smooth surfaces tend to slip, straps and / or fastening loops can then be attached to the carrier. For example For footwear, the wearer can be cut into circular disks with holding loops For example, elastic bands are attached with which these discs are temporarily held on the shoe. These Elastic bands "do not have to absorb any significant tangential forces.

When used on vehicle wheels, strips can be provided, the width of which corresponds to the width of the vehicle wheel. These strips can be fastened by means of simple straps - under no circumstances according to Art. A ... ·.
