The present invention relates to anti-skid devices or snow chains are designed for installation on the tires of vehicles and, in particular, snow chains, which, after installation, have a limited amount of space.

When the vehicle moves on a road surface covered with snow, frost or ice, its tires do not have good adhesion with the road surface may cause dangerous side slipping or skidding of the vehicle. To avoid these problems, the conventional use of anti-slip devices, commonly called snow chains.

Snow chains, usually mounted on the leading vehicle wheels sink into the snow and/or ice on the surface of the road, increasing the force of adhesion of the tread and the road surface and allowing the tires of the vehicle to achieve a good grip.

As you know, snow chains generally consist of two lateral elements (circuits, flexible cables, steel wire ropes and the like)that, when used close to the ring on the inner side and the outer side of the wheel, respectively, and which will be designated here as the inner ring and the outer ring. The data side elements connect the tive near the sites of the chain, located different ways to get a grip of the tread with the road. Part of the design includes a device for tensioning these elements, known as a tension device.

Snow chains are usually kruglozerny chain, i.e. each link in the chain is essentially elliptical in shape and is located in the plane perpendicular to the planes of the adjacent links.

Data chains besides the fact that they take up a lot of space on the tread, also take up much space on the sides of the tread due to the use of the connecting means. This is in contradiction with the growing need for modern vehicles have very small gaps, especially between the inner side of the tire and mechanical elements of the vehicle.

In documents FR 742649, US 1855279 and FR 2755644 described snow chains containing parts of a chain with links of twisted forms and the connecting element is triangular in shape, connecting the end sections of the chain.

In the document US 1667686 disclosed antiskid device comprising a cross or tread elements and the side or holding elements.

In the document US 2281655 described the anti-skid chain, containing the parts of a chain with links of twisted forms and split wut is ku for joining sections of chain to the ring in chains.

The aim of the present invention is to overcome the disadvantages of the prior art by creating chains holding limited, especially on the lateral sides of the tire, and thus does not interfere with the mechanical elements of the vehicle.

Another objective of the present invention is to provide a snow chain, which is reliable and at the same time inexpensive and easy to manufacture.

Another objective of the present invention is to provide a snow chain, which is practical and easy to use for consumers.

These goals are achieved, in accordance with the invention, by distinctive signs that are listed in the independent claim 1 of the attached claims.

Preferred variants of the embodiments of the invention are evident from the dependent claims.

The anti-skid chain according to the invention contains:

the inner ring is designed to snap on the side of the wheel facing the inside of the vehicle,

the outer ring designed to snap on the side of the wheel facing outward of the vehicle, and

the ranks of the anti-slip plots chain placed on the tread of the wheel and connecting the outer ring and the inner ring.

Data structure for connecting and joining sections circuits provide rotation plots chains around connecting and mounting elements, and at the same time, the smallest possible volume, so as not to interfere with the mechanical elements of the vehicle.

Further features of the invention will become clearer from the subsequent detailed description of the exemplary, and therefore non-limiting variant embodiment of the invention, illustrated in the accompanying drawings, in which:

Fig. 1 is a perspective view illustrating an anti-skid chain according to the invention applied to a tire of the wheel, shown from the side facing the inside of the vehicle;

Fig. 2 is a view in enlarged scale of part of Fig. 1, illustrating the triangular connecting element for the connection of sections of circuits with each other;

Fig. 3 is a view in enlarged scale of part of Fig. 1, illustrating two clamp mounting system for connecting sections of chains with inner ring of the chains;

Fig. 4 is a perspective view with spatial diversity of detail, illustrating the clamp mounting system of Fig. 3; and

Fig. 5 is a view in enlarged scale of part of Fig. 1, illustrating the lock for the closure of the inner ring chains.

In Fig. 1 shows a wheel of the vehicle having the tire 1, which is equipped with the anti-skid chain, indicated generally by the reference character 2, as anti-slip devices.

The anti-skid chain 2 contains:

element 3 that can be closed in a circle or ring on the side of the wheel facing the inside of the vehicle, hereinafter called the inner ring 3,

element (not shown), which can be closed in a circle or ring on the side of the wheel facing outward of the vehicle, hereinafter called the outer ring 4, and

the series of sections 10, 10' antiskid chains, arranged in various ways on the tread 1 of the wheel and connecting the outer ring 4 and the inner ring 3.

As shown in Fig. 2, the sections 10, 10' chain consist of chains with links of twisted forms, i.e. each circuit contains many interconnected parts 11 twisted forms. Each link 11 twisted form consists of essentially elliptical annular element, which is first twisted around its main axis.

Thus, each link 11 twisted form has two opposite portions that are adjacent to the bus 1, and two opposite parts, which protrude outward from the tread-1, acting as a destructive ice elements and helping to increase the adhesion of the tread of the tyre and the road surface.

In Fig. 1 shows that the areas 10 chains preferably have on the bus 1 diamond-shaped configuration, location and connected to each other by means of connecting parts 10' chains along the middle part of the tread 1. Accordingly, using a connecting element 4 for connecting together two sections 10 chains, which form two sides of a rhombus, and a connecting section 10' of chain.

As shown in Fig. 2, the connecting element 4 consists of a chain link having the shape of an equilateral triangle, twisted in order to adapt to the links 11 are twisted form sections (10, 10') of the chain. Thus, the twisting is performed around the axis of the different sides of the triangular link 4.

Thus, the Central parts 40 of the triangular link connecting element 4 is curved in an outward direction from the bus, while the angular parts of the connecting element 4 is curved in the direction to the bus 1, for connection to terminal units 11 sections (10, 10') of the chain.

In Fig. 1 shows that the inside is her ring 3 contains the core 31, consisting of open metal cable or multiple twisted metal veins, covered with open plastic shell 30. Clamp mounting system 5 is used to join the inner ring 3 of the ends of the sections 10 chains, which form diamonds.

As shown in Fig. 3 and 4, clamp mounting system 5 includes a collar 50 that is designed for installation on the inner ring, and the connecting element 60 that is designed to attach to the end link 11 section 10 of the chain.

The clamp 50 is made of a metal plate bent in a U-shape around the core 31 of the inner ring 3, for the formation of essentially semi-cylindrical part 51, which covers the core 31 of the inner ring. Thus, the clip 50 can be rotated around the core 31 of the inner ring.

From the semi-cylindrical part 51 of the clip 50 depart two essentially flat pentagonal section 52, which has two through holes 53, the axes of which are in the transverse direction relative to the axis of the semi-cylindrical part 51. The flat part 52 of the clip are parallel to each other and are separated from each other so as to leave an empty space between them.

Between the semi-cylindrical part 51 and the flat portions 52 are narrowing 54 formed by the outer grooves and abrami, directed inward, so as to avoid separation of the core 31 of the inner ring 3 and the semi-cylindrical part 51 of the clip 50.

The connecting member 60 is made of a metal plate bent in a U-shape around the end of the link 11 of the twisted shape of the corresponding section 10 of the chain and having a tapered adjacent to each other edge 62. Thus, the connecting member 60 has two adjacent to each other edge 62 and a curved portion 61 a small width, which forms a hole 65 through which the end link 11 twisted form of section 10 of the chain. The curved portion 61 of the connecting element can be twisted relatively adjacent to each other edge 62 so as to adapt it to the shape of the link 11 twisted forms.

A through hole 63 is made adjacent to each other, the edges 62 of the connecting element 60. Adjacent to each other edge 62 of the connecting element 60 is placed inside the empty space between the two flat portions 52 of the clip 50, so that the holes 53 of the flat parts of the clamp are aligned with the holes 63 of the connecting element 60. The finger or rod 55 is inserted then located on the same axis holes 53 and 63 for swivel coupling element 60 with collar 50 can be rotated around the axis of the finger 55.

It should be noted that the clamp 50 can in order to turn around the core 31 of the inner ring, and that the connecting member 60 can be rotated relative to the clamp 50 around a transverse finger 55. Next, clamp mounting system obtained by connecting the clamp 50 with the connecting element 60 has a reduced thickness and occupies less space on the inner ring 3, and thus, does not interfere with the mechanical elements of the vehicle.

The connecting member 60 can be made of a single block having the shape of a parallelepiped with dimensions and thicknesses of the two adjacent to each other of the edges 62, which has a curved part of the U-shaped form corresponding to the curved part 61.

Moreover, the connecting member 60 can be replaced by a chain link round or flat form, attached to the end link 11 twisted forms and to cross the finger 55 of the clip 50.

In Fig. 1 shows that the ends of the core 31 of the inner ring 3 is attached to the two pin elements 80 and 90 forming part of the lock 8 of the inner ring, which is in itself known.

As shown in Fig. 5, each clutch element 80 and 90 of the lock 8 is made of two plate elements, which form a socket for fastening with the possibility of rotation of the respective ends 31A and 31b of the core 31 of the inner ring 3. In addition, each clutch element 80 and 90 of the lock 8 contains the corresponding hinge 81 91, placed inside the end link of the corresponding section 10 of the chain. Clutch element 90 includes curved hook end 92, which clings to the finger 82, available at the end of the other clutch element 80.

In this case, the tapered shape of the two clutch elements 80, 90, each of which is made of two stacked plate elements together, also helps to prevent the contact of the lock 8 with mechanical elements of the vehicle.

The end links of the sections 10 of the chain can be attached to the outer ring by means of any known mounting systems, which are therefore not illustrated here. In fact, in this case, the size of the mounting system has a smaller effect.

It should be noted that the specialist in the art can be made many changes and modifications of the present variant embodiment of the invention without leaving the scope of the present invention specified in the attached claims.
