 Conventionally, as shown in FIG. 7, it is formed by a line connecting the tips 201 of the hooks 200 along the hooks 200 provided on the outer edge portion 101 of the tire slip stopper 100. The elastic tightening ring 300 having a diameter smaller than the diameter of the circle is stretched and hooked with a plurality of pieces (for example, three pieces), and the tire slip stopper 100 is tightened by the restoring force of the tightening ring 300 so that the tire slip stopper 100 is closely attached to the tire. ..

[0003]

[Problems to be solved by the device]

 However, in the above-described conventional technique, it takes a lot of labor to pull the tightening ring 300 to hook it on the hook 200. Therefore, depending on the person (elderly person, woman, etc.), most of them are outdoors in the cold winter. It was a very difficult task because it was a work done in Japan.

Further, since the tightening ring 300 is in the form of a thin string that can be pulled and stretched, it is necessary to stack a plurality of hooks in order to obtain a sufficient tightening force. It was bad.

The present invention has been made in view of such problems of the prior art, and an object of the present invention is to easily and surely tighten the outer edge of the tire slip stopper mounted on the tire. To provide a simple tightening tool.

[0006]

Means for Solving the Problems The technical means made by the present invention to achieve the above-mentioned object are a tightening rope which is locked along an outer edge of a tire slip stopper, and both ends of the tightening rope. It is composed of a stopper that adjusts the tightening to a predetermined ring shape and holds it in a predetermined tightened state.The stopper holds the above tightening rope and rotates in the releasing direction when pulling in the tightening direction of the rope. Is rotatably provided.

[0007]

[Action]

 By the above technical means, the tightening rope is locked along the outer edge of the tire slip stopper wound around the tire, the rope is arranged in a ring shape along the outer edge, and the stopper of the driving clip of the stopper is attached. When both ends of the tightening rope are pulled in the tightening direction while rotating in the releasing direction, the ring shape of the rope gradually becomes smaller and the outer edge of the tire slip stopper is tightened toward the center of the tire side surface.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

The tightening tool A of the present invention comprises a tightening rope 1 that is locked along each outer edge b of the tire anti-slip device B, and a stopper 3 that adjusts the tightening rope 1 by tightening. The outer edges b of the tire slip stopper B wound around the tire C are tightened toward the center of the side surface of the tire C.

The tightening rope 1 is made of, for example, a desired synthetic resin material having high tensile strength and flexibility, and is formed by each outer edge b of the tire slip stopper B wound around the tire C. The length is such that a large-diameter ring having a diameter equal to or larger than the diameter can be formed, and is thick enough to fit in the claw portion b'1 of the locking hook b'provided at the tip of the outer edge b. The rope 1 is formed in a desired ring shape, both ends 1a, 1a are arranged in parallel toward the inside of the ring, and the both ends 1a, 1a are slidably contacted between the drive holding pieces 5, 5 of the stopper 3. A stopper 3 is integrally provided on the tightening rope 1 through which the hooks 2 and 2 are provided at the ends of the both ends 1a and 1a.

The tightening rope 1 is not limited to the high-tensile one made of the above-mentioned synthetic resin material, but may have other high-tensile properties and flexibility. It may be made of a material having elasticity and flexibility.

The stopper 3 comprises a rope guiding gate 6 standing on the surface of the pedestal 4 of a desired shape, and driving gripping pieces 5 and 5 adjacent to each other above the gate 6, and in this embodiment, further. A locking hole 7 is formed at a position below the gate 6.

The driving pinching piece 5 is provided with, for example, a corrugated inclined pinching surface 5a at the tip thereof, and a rear end 5b side thereof is pivotally mounted on the surface of the pedestal 4 so as to be rotatable in the vertical direction, and at the same time the pinching direction is always set. The two driving clamping pieces 5 and 5 are provided so as to be adjacent to each other, and the tip clamping surfaces 5a and 5a of the two driving clamping pieces 5 and 5a are opposed to each other. The gap between them is narrower than the width where both ends 1a, 1a of the tightening rope 1 are arranged side by side, except when it is rotated in the releasing direction (upward in the drawing) against the biasing force. , The both ends 1a, 1a of the rope 1 are always clamped by the clamping surfaces 5a, 5a, and the rope 1 is clamped in a predetermined loop shape and held in a predetermined clamped state. The driving clamping pieces 5, 5 may be configured so that the clamping surfaces 5a, 5a have a certain gap as described above, but both surfaces may abut when facing each other. Needless to say.

Further, in this embodiment, the drive blocking member 8a is rotatably provided on one of the driving holding pieces 5, and the fitting portion 8b for fitting the blocking member 8a to the other driving holding piece 5 is provided. The blocking member 8a is fitted to the fitting portion 8b to prevent the driving clamping pieces 5 and 5 from rotating except during tightening work, and prevent the tightened state from being unintentionally released during traveling or the like. There is.

A method of using the above-described tightening tool A will be described. First, as described above, a desired loop-shaped tightening rope 1 is provided at each outer edge b of the tire slip stopper B by the stopper 3. Lock along the locking hooks b '. At this time, the driving pinching pieces 5, 5 are rotated in the releasing direction to temporarily release the pinched state of the rope 1, and the outer sides of the tire slip stopper B when the diameter of the tightening rope 1 is wound around the tire C. It can be locked easily by loosening it so that it has a diameter larger than the diameter formed by the edges b ....

Then, the locking hole 7 of the stopper 3 is locked and fixed to a desired locking hook b ′, and both ends 1a, 1a of the tightening rope 1 are tightened in the tightening direction (see FIGS. 2 and 5). If it is pulled in the direction indicated by the arrow x), the drive clamping pieces 5, 5 will be spread out against the urging force in the clamping direction in conjunction with the movement of the both ends 1a, 1a in the arrow x direction. Since the tightening rope 1 is pivoted in this manner, the clamped rope 1 is released from the clamped state and pulled by a predetermined length, so that the annular shape gradually becomes smaller in diameter.

Therefore, the tire slip stopper B, which is connected through the locking hooks b ′ ... by the pulling operation of the tightening rope 1, is tightened toward the center of the side surface of the tire C, and then tightened. When the pulling operation of the rope 1 is stopped, the driving clamping pieces 5, 5 are rotated in the clamping direction by the urging force of the ropes 1, and the clamping surfaces 5a, 5a clamp the ends 1a, 1a, respectively. By hooking the hooking portions 2 and 2 on predetermined locking hooks b ′ and b ′, the tightening rope 1 is tightened and held in a predetermined ring shape. The tightening rope 1 is maintained in its tightened state by the urging force of the driving gripping pieces 5, 5 in the gripping direction and the strong gripping force by the returning force of the tightening rope 1 (indicated by arrow z in FIG. 6). Is done.

Further, the hooking portion 2 is made of a ring-shaped elastic body in the illustrated example, but needless to say, may not be an elastic body, and may be formed in another desired shape, for example, a hook shape. It is also possible to use a desired locking hook b'provided on each outer edge b ... of the tire slip stopper B.

In the present embodiment, the tightening rope 1 is provided in advance in the form of a ring with the stopper 3 for ease of use, but the tightening rope 1 and the stopper 3 are separately provided. As a matter of course, it may be used in combination on site, and the non-metallic tire slip stopper formed in a net shape has been described. The above-mentioned tire slip stopper is merely an example for explaining the usage state, and the tire slip stopper is not limited to this. It may have a conventionally known shape (for example, another net shape or a ladder shape). It can be applied to all kinds of anti-skid tires, and can be either non-metallic or metallic.

[Effect of the device]

 The present invention comprises a tightening rope that locks along the outer edge of a tire slip stopper, and a stopper that allows both ends of the tightening rope to pass through each other to adjust the tightening into a predetermined ring shape and to hold the tightening rope in the predetermined tightening state. However, the stopper holds the above-mentioned tightening rope, and is provided with a driving holding piece that turns in the releasing direction when the rope is pulled in the tightening direction so that it can be turned to the outer edge of the tire slip stopper. To lock the rope, it is only necessary to lock the above-mentioned one tightening rope, and if both ends of the tightening rope clamped by the stopper are pulled to the desired extent, the rope will move in the pulling direction. Then, the drive pinching piece rotates to release the rope pinching action, and if the rope is pulled as much as necessary in that state, the ring shape of the tightening rope gradually becomes smaller and the tire slip stopper Since it can be tightened in the direction of the center of the tire side, the work of locking the tightening tool to the tire anti-slip device is extremely easy, and since both ends of the rope are pulled and tightened, tightening can be done very quickly and reliably. Yes Easy to use and very convenient.
