Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tire non-slip device mounted on an automobile tire when traveling on a snowy road.

[0002]

[Prior art]

 This type of anti-slip device winds a winding body made of a non-metallic material around the outer circumference of a tire mounted on a wheel, and engages a fastening ring on one side edge of the winding body which is an inner side of the vehicle. On the other hand, a plurality of hook-shaped hooks in the circumferential direction are provided on the other side edge of the wound body on the outer side, and an elastic ring such as a rubber band is hooked on all the hooks.

This type of non-slip device is easy to put on and take off because the winding body can be wound around the outer periphery of the tire simply by engaging the elastic ring with the hooking device, and is widely used.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned prior art, when the vehicle suddenly starts or turns sharply on an ice and snowy road, or climbs up while idling, the elastic ring may expand and contract, and the winding body is eccentrically displaced from the tire and disengages from the tire. Sometimes. This can be solved to some extent by forming the elastic ring with a material that is difficult to stretch, but in that case, it requires a considerable amount of force to engage the elastic ring with the latch, making it difficult to attach and detach the winding body. become.

According to the present invention, a mounting board is provided on a wheel, and an engaging portion is formed on the mounting board, and a hooking device is engaged with the engaging portion so that the winding body can be attached to the tire. Accordingly, it is an object of the present invention to provide a tire slip prevention device capable of solving the above-mentioned problems of the prior art.

[0006]

[Means for Solving the Problem] A specific means for solving the problem in the present invention is to wind a winding body 4 made of a non-metallic material around the outer periphery of a tire 3 attached to a wheel 2 and to provide an inner side with respect to a vehicle. Anti-slip device in which a fastening ring 5 is engaged with one side edge of the winding body 4 to be the In the above, the wheel 2 is provided with a mounting board 7, and the mounting board 7 is formed with a hooking portion 8 which is arranged substantially opposite to each hook 6 and which can be hooked with the hook 6.

[0007]

[Action]

 Before use, the mounting board 7 is previously bolted to the outer surface of the wheel 2 of the vehicle. Before traveling on the ice and snowy road, the winding body 4 is wound around the tire 3, the fastening ring 5 is engaged with the inner edge of the winding body 4, and a large number of circumferential hooks 6 provided on the outer edge of the mounting board 7 are attached. It is engaged with the engaging portion 8 and the wound body 4 is attached to the tire 3.

[0008] While the vehicle is running on an icy and snowy road, if a force that shifts the winding body 4 in the circumferential direction or the axial direction of the tire 3 is applied to the winding body 4, the winding body 4 is slightly elastically deformed, but the position of the hook 6 is at the mounting board. Since it is substantially fixed by 7, it does not change and the outer edge of the winding body 4 is prevented from shifting.

[0009]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 and 2, reference numeral 1 denotes an anti-slip device mounted on a vehicle tire 3. The tire 3 is a general pneumatic tire mounted on the wheel 2 fixed to the axle 11. The tire slip prevention device 1 includes a winding body 4 wound around the tire 3 and a mounting board 7 that is bolted to the wheel 2.

The winding body 4 is made of a non-metallic material such as rubber or plastic, and has a ladder portion 4A at the center in the left-right (width) direction and net portions 4B at both left and right sides thereof. Then, both ends in the circumferential direction are connected by the connecting fittings 12. This winding body 4 is provided with a plurality of circumferential fasteners 13 at one side edge (inner edge) that is an inner side with respect to the vehicle when wound around the tire 3 by utilizing the holes of the net portion 4B. The fastening ring 5 is locked to the locking tool 13.

The fastening ring 5 is an endless rope formed of a material that is difficult to stretch, and when connecting both ends of the winding body 4 with the connecting fitting 12, both ends of the fastening ring 5 are also connected to form a ring. The extension of one side edge of the winding body 4 is restricted. The wound body 4 has a plurality of hook-shaped hooks in the circumferential direction on the other side edge (outer edge) that is outside with respect to the vehicle when wound around the tire 3 by utilizing the holes of the net portion 4B. 6 is provided by caulking, and this hooking tool 6 can be hooked on the mounting board 7.

The mounting board 7 has a fixed plate 15 and a latch plate 16, the fixed plate 15 is detachably fixed to the wheel 2, and an annular plate 17 is welded to the outer periphery of the fixed plate 15. A bolt hole 18 that is long in the direction is formed. The retaining plate 16 is formed in an annular shape, the inner peripheral side of the inner surface of which is in contact with the annular plate 17, and is attached to the fixed plate 15 by a bolt 19 penetrating the bolt hole 18, and the bolt 19 is attached to the bolt hole 18. It is rotatable with respect to the fixed plate 15 within a range in which it can move.

On the retaining plate 16, a plurality of engaging portions 8 arranged in an annular shape are formed in a plurality of radial steps. The engaging portion 8 of each step is an arcuate slit and is arranged substantially opposite to the engaging member 6, and each engaging member 6 is engaged from inside or outside. The connecting member 12 also serves as the hook 6. The tire 3 has different tread parts depending on the brand, tread pattern, wear state, etc., but by providing the engaging parts 8 in multiple stages in the radial direction, the winding body 4 can be pulled without sagging. Then, the hook 6 can be hooked.

Further, if the engaging portion 8 has a long hole shape, it can be engaged with the engaging portion 8 even if the engaging tool 6 is slightly displaced in the circumferential direction. Therefore, the mounting board 7 may be formed by integrally forming the fixed plate 15 and the latch plate 16, that is, a single plate. On the contrary, if the hooking plate 16 can be adjusted in phase in the circumferential direction with respect to the fixed plate 15, the hooking portion 8 may be a circular hole. The tool 6 may be a metal fitting having a ring portion fitted therein.

[0015]

[Effect of device]

 According to the present invention described in detail above, the winding body 4 made of a non-metallic material is wound around the outer periphery of the tire 3 attached to the wheel 2 and is fastened to one side edge of the winding body 4 which is the inside of the vehicle. A plurality of hooks 6 are provided in the circumferential direction on the other side edge of the winding body 4 which is engaged with the linking ring 5 and is on the outside of the vehicle. Since the hooks 6 are formed so as to be substantially opposed to the hooks 6 so that the hooks 6 can be hooked, the hooks 6 should be hooked on the mounting board 7 in a stationary state. Therefore, even if the vehicle suddenly starts or turns sharply on a snowy road, or climbs up while spinning idly, the winding body 4 does not move and is not eccentric, and it is more certain that the winding body 4 is removed from the tire 3. It can be prevented.
