Description

[Detailed Description of the Invention] Purpose of the Invention Industrial Application Field The present invention relates to a device for mounting and tightening a tire anti-slip device on a tire.

Problems to be Solved by Conventional Technologies and Ideas Conventionally, as a non-slip device for automobile tires, a plurality of non-slip members also made of a chain are placed at intervals between a pair of side strips made of a chain. However, recently, in place of this, belts made of synthetic resin are strung between a pair of wires to connect them. As a device for connecting both ends of each wire of the tool and tightening it to the tire, a connecting fitting with a hook formed at the tip at one end of each wire is used.
Connecting fittings to which the proximal ends of the bands are fixed are connected to the other ends of the bands, and the tips of the bands are connected to the ends of the rectangular locking rings in which both ends of a pair of corresponding guide rods are connected by locking rods and tightening rods. A movable rod is slidably passed around a pair of guide rods, and the movable rod is hung around the movable rod of the fastener and folded back to the same side, and the locking rod of the locking ring is locked to the hook, and the wire is It has been proposed that both ends of the wire be connected to each other. Although this tightening device has the advantage of being easy to attach and detach and can be retightened, twisting of the wire could cause the connecting fitting to tilt and bite into the side of the tire, or come into contact with the tire house or nearby equipment. .

The present invention has been developed in view of the above points, and it is an object of the present invention to provide a tightening device that prevents the connecting fitting from tilting even if the wire is twisted.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

A first embodiment of the present invention, shown in FIGS. 1 and 2, is arranged between a pair of wires 1, 1 arranged along both side parts b of a tire a, and across a tread part c. A first connecting fitting 6 is connected to one end of each wire 1 by caulking, and the connecting part 62 is formed into a narrow width. At the same time, a hook 61 is formed by folding the tip end outward, and at the other end of each wire 1, a second coupling part 72 is similarly formed with a narrow width. The metal fittings 7 are connected by caulking, and the connecting parts 62 and 72 of the first and second connecting metal fittings 6 and 7 are formed on the end surface of the connecting part 21 of the belt 2 connected to the end of the wire 1. It is tightly fitted into the groove 22. The proximal end of an elongated cloth band 8 is bent and fixed to a bridging portion 71 formed on the second connecting fitting 7 by punching, and a fastener 9 is attached to each band 8 so as to be movable. installed. This fastener 9 is made of a pair of guide rods 91a, 9 that correspond to each other by turning a round steel wire.
A hook-shaped pressing portion 91d with one guide rod 91a extended is formed on the tightening rod 91b side of a rectangular locking ring 91 in which both ends of the ring 1a are connected by a tightening rod 91b and a locking rod 91c. The movable rod 92, whose outer periphery is knurled to increase the frictional resistance with the band 8, is freely slid between the guide rods 91a, 91a, and the tip of the band 8 is inserted from the back side of the locking ring 91 to the surface. The fastener 9 is attached to the band 8 by passing it through the side, turning the movable rod 92, and passing it from the front side to the back side again, and the locking rod 9 of the locking ring 91
1c is hooked onto the hook 61 of the first connecting fitting 6, and the tip of the band 8 is pulled toward the second connecting fitting 7 to tighten it. Tightening rod 91 of retaining ring 91
By being pinched between the movable rod 92 and the movable rod 92, loosening is prevented and both ends of the wire 1 are firmly connected, and as the connecting fittings 6 and 7 approach each other, the wire 1 is tensed and Accordingly, as shown in FIG. 1, each band 2 is stretched across the tread portion c and stretched between both side portions b, and is tightly attached to the tire a. Since the connecting parts 62, 72 of the connecting fittings 6, 7 with the wire 1 are tightly fitted into the groove 22 of the belt 2, the connecting fittings 6, 7 are not tilted and are not in contact with the side part b of the tire a. It's summery.

On the other hand, to remove the tire chain from the tire a, push the pressing part 91d of the locking ring 91 in the direction of the When the movable rod 92 was pressed toward the tightening rod 91b due to the tension of the band 8, the guide rods 91a and 9
1a, the force pinching the base of the folded part of the band 8 is weakened, and the band 8 rotates around the moving rod 92 due to the tension and slides in the direction of loosening, so the locking ring 91 is hooked. It can be easily removed from 61.

A second embodiment of the present invention, shown in FIG.
The first and second parts are connected by caulking to both ends of the
The connecting portion 62 of the connecting fittings 6a, 7a with the wire 1
Projecting pieces 63a, 73a are symmetrically formed on both sides of a, 72a, and one of the projecting pieces 63a, 73a is tightly fitted into the groove 22a formed in the end surface of the connecting portion 21 of the belt 2. It is designed to prevent the connecting fittings 6a, 7a from tilting. The reason why the protrusions 63a and 73a are symmetrically formed on both sides of the connecting metal fittings 6a and 7a is to use them both on the inside and outside of the tire a, and by tightening the band 8, the connecting metal fittings In order to prevent interference with the connecting portion 21 of the belt 2 when the protrusions 6a, 7a are tilted toward the center of the tire a, the inner edges of the protrusions 63a, 73a are tapered to widen toward the other end.

As specifically explained in the above embodiment,
The tire skid tightening device of the present invention has a plurality of wires arranged across the tread of the tire between a pair of wires arranged in a substantially circular shape on both sides of the tire. In a tire skid device in which synthetic resin belts are connected at intervals, a connecting fitting having a hook formed at the tip is attached to one end of the wire, and a connecting fitting having a proximal end of the band fixed to the other end. The movable rod is slidably inserted into the pair of guide rods of a rectangular locking ring in which both ends of the corresponding pair of guide rods are connected by a locking rod and a tightening rod. The locking rod of the locking ring is hooked to the hook, and both ends of the wire are connected to each other. The gist is that a part of the connecting fitting is fitted into a groove formed in the belt connected to the end of the wire to prevent tilting, and the locking ring is hooked onto the hook. A simple procedure like pulling the band can firmly connect both ends of the wire, and simply pulling the locking ring loosens the band and allows it to be immediately removed from the hook, preventing the tire from slipping. The fitting can be removed quickly, and since the connecting part of the connecting fitting fits into the groove of the belt, even if the wire is twisted, the connecting fitting will not tilt, and the side part of the tire can be easily removed. This prevents the tires from digging into the wheels and causing damage, and from colliding with tire housings, etc., resulting in safer driving.
