    A tire chain with separable chain strands the end links of which are connectable at each separation point by use of two connecting elements which can be hooked into each other and which are each safely connected with an end link, wherein each connecting element has a body comprising at least one portion bounding an insertion slot which portion has a cross-section decreased at its free end at the expense of its width and wherein the width of the insertion slot is smaller than the height of each of those portions of the body which bound the insertion slot.

    (54) CAR TIRE CHAIN
    The invention relates to chains mounted on automobile tires, in particular to snow chains, having connectors made in the form of two mutually meshed links. A known anti-skid chain for car tires has connectors made in the form of two mutually engaged links located in mutually perpendicular planes and inseparably connected with other chain links, one of the connectors having a C-shaped eyelet with a slit for inserting another links After inserting another Even into the prostrum, the end of the C-shaped eyelet is driven inwards, reducing the size of the slot by plastic deformation of the link and thus providing a connection of the links l. A disadvantage of the known construction is the high labor-intensiveness of the operations of connecting and disconnecting chain links, which require special tools for plastic transformations of the connecting link, which greatly complicates the installation and removal of the chain from the car wheel. The purpose of the invention is to facilitate the assembly and disassembly of the chain. The goal is achieved by the fact that all the connector links are full with a slot, bounded ends and ears with X-shaped wedge surfaces intersecting in pairs in the middle longitudinal plane of the link at an angle of EO to one another, and the maximum slot ball is smaller than the thickness of each end of the ears . This provides the possibility of connecting and disconnecting the connector parts without an auxiliary tool by inserting the wedge surfaces of the links into mating with each other and their subsequent rotation through 90 ° first in one and then in another mutually perpendicular planes. The end of the ear, limiting the slot of the connector, may have a protrusion directed to the connecting part of the link. The connecting part of the connector link may have a protrusion in the middle, which is directed towards the slot. In addition / presumably to the connecting part of the connector section. was made with the extension and matched with the semi-circular sections of the link with wedge surfaces.
    Achieved stability of connecting links in severe conditions of chain operation on a car tire.
    FIG. 1 shows the side of the chain connector; in fig. 2 - connector link, top view; in fig. 3 is the same, section aa in FIG. in fig. 4 is the same section BB in figure 1 on. FIG. 5 is another possible embodiment of chain connector links.
    The ring links 1 and 2 of the anti-skid chain are connected in place of the connector by two identical links 3 and 4 having a C-shaped eye with a slot 5. Each of the links 3 and 4 of the connector is made with half-ring sections B and 7 adjacent to the connecting part 8, which is made with the extension (fig. 2-3) and conjugated with the mentioned areas b and 7 by means of the wedge of new surfaces 9, 10, 11 and 12. The ends 13 and 14 of the C-shaped eyelet formed by the semi-ring sections 6 and 7 have reversed to the slot 5 X-shaped wedge surfaces
    15, pairwise intersecting in the mid-plane of the link at an angle of 90 ° one to OTHER:
    To avoid spontaneous separation of chain links, the width I of slot 5 should be less than the thickness G and at the end 13 and 14 of the ears. At the end of the 13 eyelet there is a protrusion
    16, directed towards the connecting part 8 of the link, which, in turn, has a protrusion 17 in the middle, directed towards the slot 5, which ensures a more reliable fastening of the link 1.
    The cross section of section 7 is larger than that of section 6, which has an oval cross section (Fig. 4), which, without prejudice to the ease of separating the links, increases the strength of the connecting elements.
     For reasons of strength, it is recommended to use small steps of 1,2,3 and 4 chains for tacking, preferably a pitch may be within 3-3.5 of the thickness of links 1 and 2 of the chain. At such a step, the slant 5 is oblique, as shown in figure 1.
    FIG. Figure 5 shows another embodiment of the connector links 3 and 4 according to the present invention. In this case, a permanent connection of the connector link 3 with the ring link 1 is used. The proposed circuit embodiments allow quick and easy connection and disconnection of its sections at the connector sites without using any kind of auxiliary tool and at the same time guaranteeing reliable connection of the chain, which is very important quality for removable devices such as anti-skid chains.
    invention formula
    1. Chain for car tires, predominantly an anti-skid chain having connectors made in the form of two mutually engaged links arranged in mutually perpendicular planes and non-detachably connected with other chain links, at least one of the connector links having a C-shaped eyelet with a slit for inserting another link, characterized in that, in order to facilitate the assembly and disassembly of the chain, all the connector links are made with a slit bounded by the ends of the lugs with X-shaped wedge surfaces intersecting in pairs Independent user link longitudinal plane at an angle to the other, wherein the greatest width of the slot is less than the thickness of the sectional area of each of the ends of the lugs.
    2. Chain in accordance with Clause 1, .that t and y and with the fact that the end of the ear, the bounding slot of the connector link has a protrusion directed to the connecting part of the link.
    3. Chain of PP. 1 and 2, characterized in that the connecting part of the connector section has in the middle a protrusion directed to the slot.
    4. Chain of PP. 1-3, characterized in that the connecting part of the connector section is made
    with overshoot and mating with half-ring portions of the link with wedge surfaces.
