Since the connecting tool 10 is interposed in the gap provided between the
By changing this connecting tool 10 with one having a different length, it is possible to change the degree of reduction of the above-mentioned peripheral diameter by the fastening means, whereby one kind of anti-skid device for a tire has a different diameter to some extent. Can be shared with various tires.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

As shown in FIG. 1, the belt-shaped main body 1 of the fastener for a tire has a form in which a net and a lattice are combined as a whole, and a plurality of main bodies, four in this case, are formed in the longitudinal direction. It is divided into two pieces. Then, the main body divided pieces 2 adjacent to each other are connected in a band shape by hooking a C-shaped latch 4 between the hooking holes 3 provided at the respective four corners. The lattice-shaped wide portions of the main body divided pieces 2 each form a grounding portion 5, and a slip-proof rivet 6 is embedded therein.

One side edge portion 2a of the main body divided piece 2 has a mountain-shaped concavo-convex shape, and is provided at predetermined intervals, and in this case, a hooking hole 7 as an engaging portion is provided at the top end of each convex portion.

Further, fastening rods 8, 8 are provided so as to face each other at both ends of the side edge portion 2a. The length of the fastening rod 8 is half the length of the main body divided piece 2 or less, and a hooking hole 9 is provided at each tip. 1
Reference numeral 0 is a substantially C-shaped connecting member which is engaged between the engaging holes 9 in a state where the tips of the two fastening rods 8 are pulled toward each other.

Reference numeral 11 denotes a connecting member which connects the two fastening rods 8 and 8 to each other and hooks and connects an intermediate portion of each of the fastening rods 8 to each of the fastening holes 7 of the side edge portion 2a. It is wrapped around 8 and fixed. Reference numeral 8a designates a plurality of annular projections for positioning when the position of this fixation is changed according to the size of the tire.

The hooking hole 7, the fastening rod 8, the hooking hole 9, the connector 10 and the connecting member 11 constitute a fastening means for the one side edge portion 2a of the strip-shaped main body 1.

Reference numeral 12 is a vertical penetrating member that penetrates the other side edge portion 2b of the main body divided piece 2 and is bent in a wave shape, and a substantially C-shaped hanging tool 13 is hooked on the central portion of the portion that bulges outward. ing.

Next, the operation of the above configuration will be described.

First, a strip-shaped main body 1 as a connected body of four main body divided pieces 2.
The ends of the fastening rods 8, 8 provided on each of the above are pulled toward each other, and the connecting tool 10 is interlocked between the hooking holes 9, 9.

Next, the connecting member 11 attached to each of the fastening rods 8 and 8.
As shown in FIG. 2, each of the main body division pieces 2 has a side edge portion 2a on which both ends of the fastening rods 8,
As a result, the lengths between both ends are shortened, and a curved surface that is similar to the shoulder portion of the outer periphery of the tire A is formed in the width direction of the belt-shaped main body 1.

Therefore, the belt-shaped main body 1 is wound around the tire A in the same manner as a conventional tire chain so that the side edge portion 2a side faces the inside of the tire A, and both ends are connected in a ring shape by the connecting fittings 14.

After that, as shown in FIG. 3, if, for example, a strong rubber ring 15 as a fastening means is spanned between the hanging parts 13 that are scattered in the circumferential direction along the front side of the tire A, the belt-shaped main body 1 The peripheral diameter of the other side edge portion 2b is also reduced, and the tight fastening and mounting to the tire A is completed.

However, since the tire diameter of an automobile often differs depending on the type of vehicle, it is necessary to prepare a tire slipper that is conventional and suitable for each tire size.

However, in the structure described above, the eight connecting rods 8 as the only members that prevent the expansion and contraction of the length dimension of the strip-shaped main body 1 having a mesh shape and capable of expanding and contracting in the longitudinal direction have a total extension. The length is set to be shorter than the length of the strip-shaped main body 1, and the adjacent fastening rods 8 are connected to each other by a connecting tool 10.

Therefore, if several kinds of connecting tools 10 having different lengths are prepared and placed, the main body portion of the belt-like main body 1 is highly stretchable, and in the case of this embodiment, only four connecting tools are connected. By simply replacing the tool 10 with a specific length corresponding to each tire size, one kind of anti-skid device for tires can be commonly used even for tires having considerably different diameters.

Therefore, it is not necessary to prepare different sizes of anti-slip tool molds for each different tire size, as in the past.
Therefore, the production cost can be kept low.

In addition, the shapes of the respective constituent members in the above embodiment, for example, the main body divided piece 2, the hooking holes (engaging portions) 7, the fastening means 8 to 11
The object of the present invention can be achieved even if the configuration is appropriately changed.

[Effects of the Invention] As is apparent from the above description, the anti-skid device for a tire according to the present invention has a belt-like main body 1 having a shape such as a net or a grid and wound around the outer periphery of the tire, and the wound body in the wound state. The belt-shaped main body 1 comprises a plurality of main body divided pieces 2 and fastening means for reducing the peripheral diameters of both side edge portions of the belt-shaped main body 1 along the circumferential direction of the inner and outer side surfaces of the tire. The fastening means for connecting one side edge portion of the strip-shaped main body 1 to each other in the longitudinal direction is provided with the engaging portion 7 provided at one side edge portion 2a of the main body division piece 2 at a predetermined interval. ,
A fastening rod 8 is provided so as to project from both ends of the side edge portion 2a so as to face each other, and has a length dimension that is less than half the length of the main body divided piece 2, and the tip ends of these fastening rods 8 and 8. Tires having different diameters are provided because they are provided with a connecting tool 10 for connecting in a state of pulling each other and a connecting member 11 for connecting the engaging portion 7 to an intermediate portion of the connecting rod 8 in the connected state. However, corresponding to this, it is possible to commonly use one type of anti-skid device for tires only by replacing the connecting device 10 with a different length dimension.
