Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire anti-skid device, and more particularly to a tire anti-skid device that can be easily and surely attached to and detached from a tire.

[0002]

2. Description of the Related Art As an anti-skid device for a tire, for example, a device described in Japanese Utility Model Publication No. 4-23682 is proposed. In this non-slip device, a coil spring body is formed in a straight rod shape, locking members are provided at both ends thereof, and a plurality of hook members are slidably provided on the coil spring body. Since the spring body can temporarily fix the chain, the chain can be easily attached.

[0003]

By the way, although the tire anti-skid device facilitates mounting of the chain,
Since the locking work is performed on the rear surface of the tire when the tire is mounted after the temporary fixing, there are difficulties such as stains on the worker's clothes and reaching the rear surface of the tire. Therefore, in view of the above-mentioned drawbacks, the present invention can easily and quickly mount any tire such as a large tire or a dual tire, and may stain clothes or the like. It is an object of the present invention to provide a non-skid device for a tire.

[0004]

That is, according to the present invention, the total length of the tire is slightly shorter than the total length of the tire and is attached along the outer circumference of the tire. Stop members provided at intervals, locking members provided on the other side edge of the grounding member at appropriate intervals, and rod-shaped hollow members that are fixed to both ends of the side edge of the grounding member on the stop member mounting side. Member, projecting hooks for locking rod-shaped members provided at both ends of both side edges of the ground member, and movably inserted to the rod-shaped member so as to connect the rod-shaped member and movably attached to the stopper member. A stop wire and a telescopic mounting member attached to both ends of the locking wire and attached to the locking member located on the tire surface side when mounted on the tire.

[0005]

According to the present invention, when the ground contact member is placed from above along the outer peripheral surface of the tire, the rod-shaped member protruding from the rear surface of the tire is used, so that the operator does not have to reach for the rear surface of the tire. Also, the grounding member can be tightened. Further, in the present invention, it is not necessary to directly tighten the grounding member on the tire rear surface, that is, the grounding member can be tightened on the tire rear surface side at the same time as the tire front surface side tightening work, that is, only once.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a tire anti-skid device according to the present invention. The anti-skid device includes a flexible grounding member 1, a stop member 2 provided at a side edge of the grounding member 1 and a locking member. A member 3, a rod-shaped member 4 fixed to both ends of the ground member 1, and a locking wire 5 connecting the rod-shaped members 4 are provided. Reference numeral 6 in the drawing denotes a protruding hook for catching the rod-shaped member 4 which is pulled from the back side of the tire to the front side so as not to slip off.

The grounding member 1 is placed from above along the outer peripheral surface of the tire and attached so as to surround the entire circumference, and is formed in an appropriate pattern having a slip preventing effect, and the total length L is the tire. The width W is slightly shorter than the circumference and the overall width W is larger than the tire width. It should be noted that a buried groove 1 for preventing the rod-shaped member 4 that bends when mounted on a tire from protruding toward the road surface is provided inward of the end portion of the grounding member 1.
3 is formed in a substantially arc shape.

The stopper member 2 is composed of a loop-shaped member formed along one side edge of the ground member 1 at an appropriate interval. In this embodiment, the stopper member 2 is arranged in the width direction (widthwise direction) of the ground member 1. ) Is fixed to each end of the holding portion 11 attached to the. The locking member 3 is formed of a hook (hook shape), and is a side edge portion of the grounding member 1 on the side opposite to the mounting portion of the stopper member 2, that is, the pressing portion 11 in this embodiment.
Is fixed to the other end of each.

The rod-shaped member 4 has a hollow rod-like shape having a hole through which the locking wire 5 passes, and has a bendability capable of being freely deformed along the outer shape of the tire. When the tire is placed from above the tire, it is designed to project linearly outward from the rear surface of the tire so that the operator can easily grip it with his / her hand.

The locking wire 5 is for fixing the grounding member 1 wound around the entire circumference of the tire by tightening it from the rear surface and the front surface of the tire, and a single wire can tighten the front and back surfaces of the tire simultaneously. Is configured. The locking wire 5 is movably inserted in advance into both the rod-shaped members 4 and the stopper member 2, and the attachment members 7 provided at both ends prevent the locking wire 5 from coming off from the rod-shaped member 4.

The mounting member 7 is made of a durable material that is not likely to be cut off when it is mounted on the tire, and is formed in a loop shape using a stretchable material. After being tightly attached to the locking member 3, the locking member 3 is attached so as not to come off.

Next, a specific method of mounting the tire antiskid device will be described with reference to FIGS. 2 to 8. First, the tire 8 is placed so as to cover the ground member 1. FIG. 2 shows the state at this time as seen from the rear surface 8R of the tire, and the rod-shaped members 4 project long to the left and right outside in a crossed state.

Therefore, as shown in FIG. 3 showing the front surface 8F of the tire, one rod-shaped member 4 is bent so as to be folded back on the front surface 8F of the tire, and is pulled so as to be locked to the protruding hook 6 from the inside. In this way, the rod-shaped member 4 which is locked while loosening is fixed with one hand, and the locking wire 5 at the tip is pulled around while being locked by the locking member 3,
As shown in FIG. 4, the attachment member 7 is hooked and fixed to the optimum locking member 3.

Similarly, as shown in FIGS. 3 and 6, the other rod-shaped members 4 and the locking wires 5 and the like are also fixed in a state where the rod-shaped members 4 are crossed (crossed) with the rear surface 8R and the front surface 8F of the tire. In this way, once the temporary fixing work is completed,
The tire 8 is moved about half a turn to perform the final tightening.

First, if the grounding member 1 is strongly pulled upward along the outer peripheral surface of the tire 8 so as to eliminate the gap with the outer circumference of the tire, as shown in FIG. It is fixed by appropriate means 9, for example, a shackle so as not to separate. Next, the mounting member 7 and the locking wire 5 which are fixed to the locking member 3 are removed, and the locking wires 5 are attached to the locking member 3 one by one while strongly pulling the rod-shaped member 4 and the locking wire 5 in order. The mounting member 7 is fixed to the optimum locking member 3 by locking. As a result, the tire anti-skid device can be attached in a tightly attached state.

[0016]

As described above, according to the present invention, when the ground contact member is placed from above along the tire outer peripheral surface, the rod-shaped member projecting from the tire rear surface is used to attach the ground contact member to the tire rear surface. It is possible to tighten the back surface of the ground member without reaching for the hand, and there is an effect that the mounting work can be performed easily and the clothes can be kept clean.

Further, according to the present invention, the tightening work on both front and back surfaces of the tire can be performed only once at a time by the pulling operation of one locking wire and two rod-shaped members connected by the locking wire. As a result, the work of mounting on the tire can be done extremely rationally and speedily, and the workability of mounting is dramatically improved, such as being freed from the conventional dirty and troublesome mounting work. .
