【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing a tire anti-slip device mounted using a tension band with a joint hook of the present invention from the outside of the tire. The tire anti-skid device includes a plurality of tread members 10 arranged at predetermined intervals, an outer rope 20 that connects an outside portion (outside of the tire 50) of the tread member 10, and an inside of the tread member 10. An inner rope (not shown) that connects the parts (inner side of the tire 50) and a tension band 40 that is attached to the outer rope 30 arranged outside the tire 50 to give a tension force are provided.

The tread member 10 has a slender mountain shape formed by covering both sides of a reinforcing material with rubber and synthetic resin, and has a long mountain shape at the ends of the outside portion and the inside portion at both ends in the longitudinal direction, respectively. A tread hook 11 is attached, and the tread hook 11 is caulked and fastened to the outer rope 20 and the inner rope, respectively.

The outer rope 20 and the inner rope are cords or braids made of non-stretchable synthetic fibers such as polyester and polyamide, and prevent the tread hook 11 from slipping sideways at the position where the tread hook 11 of each rope is attached. A hook stopper 23 is caulked, and a band hook 24 for hooking a tension band 40, which will be described later, is caulked and fixed between adjacent tread hooks 11 of the outer rope 20.

The outer rope 20 is divided into two parts having a total length that is longer by a predetermined length than the circumferential length of the sidewall portion in the circumferential direction when worn on the tire 50. Loop-shaped engaging rings 21a, 21b and engaging rings 22a, 22b are provided respectively at both ends of the outer rope 20 before division and at both ends at the division position. The joint rings are joint parts 21 and 22, respectively. The tread hooks 11 of the tread member 10 adjacent to the engaging rings 22a, 22b of the joint portion 22 at the split position among the two joint portions 21, 22 are connected by a string-like mooring member 25. The length of the mooring member 25 needs to be set longer than the fastening interval of the tread member 11 on the outer rope 20 side, but the upper limit is preferably within the limit value described later. The mooring member 25 may be made of a non-expandable material similar to the outer rope 20 or an elastic material such as a rubber cord.

The overall length of the inner rope is substantially equal to the circumferential length of the sidewall portion of the tire 50 in the circumferential position when worn, and both ends thereof are looped like the outer rope 20. A joint part consisting of a ring is provided. As shown in FIG. 2, the tension band 40 is a separate member from the above-mentioned members, and is a non-extensible ring portion 41 and extends radially outward from the ring portion 41 at a circumferential interval. A plurality of (the same number as the tread member 10) extensible arm portions 42, and an extensible auxiliary ring portion 44 connecting intermediate positions of the arm portions 42 are provided. The outer surface of the reinforcing member of the ring portion 41 is covered with rubber or synthetic resin, and the arm portion 42 and the auxiliary ring portion 44 are formed of rubber or synthetic resin. A hole 43 is provided. A joint hook 45 for attaching the outer rope 20 is attached to the hook retaining holes 43a of the two arm portions 42a among the hook retaining holes 43 of the arm portion 42. The two arm portions 42a are attached to the tire 50 with the tire anti-slip device, and when the joint portions 21 and 22 of the outer rope 20 are bound, the two arm portions 42a and the peripheral portions corresponding to the joint portions 21 and 22, respectively. The one in the directional position is selected (see FIG. 1).

As shown in FIG. 3, the joint hook 45 has a hook portion 45a that is hooked to the outer rope 20 at one end, and the hooking portion 45b at the other end is a hook hooking hole 43a of the arm portion 42a. It is fixed by crimping. The joint hooks 45 attached to the hook retaining holes 43a of the two arm portions 42a have the same shape and size. When the tire slip prevention device having the above-described configuration is attached to a tire, the inside portion of the tread member 10 on the side to which the inner rope is connected is covered on the entire circumference of the tread surface toward the inside of the tire 50 (this operation). Is carried out by slowing down the vehicle), and the individual tread members 10 are pushed into the tire 50. At this time, since the mooring member 25 connected to the joint portion 22 at the divided portion of the outer rope 20 is in an extended state, the tread member 10 is fastened to the joint portions 21 at the joint portions 21 at both ends of the outer rope 20 at wide intervals. Not only this, the tread member 10 is also fixedly attached to the joint portions 22 at the divided portions, so that the tread member 10 can be smoothly dropped into the inside of the tire 50.

When the inside portion of the tread member 10 is located inside the tire 50 at a position where it is slightly lowered, the inner rope can relax the engagement rings of the joint portions of both ends with a relatively weak force. Since it is in a non-attached state, the binding operation of hooking the rope hooks (not shown) on both engagement rings of the joint portion can be easily performed. Next, the outside portion of the tread member 10 that has fallen inside the tire 50 is pulled out to a normal position outside the tire 50. In this state, the tension band 40 is placed on the center line of the tire 50 so that the arm portion 42a faces the joint portions 21 and 22 of the outer rope 20, and the hook portion 45a of each joint hook 45 of the arm portion 42a is connected to the outer rope 20. After being hooked on the respective engaging rings 21a, 21b; 22a, 22b of the two joint parts 21, 22, the hook hooking holes 43 of the other arm parts 42 are hooked on the band hooks 24 of the outer rope 20.

According to the above procedure, the tread member 10 covering the entire circumference of the tire 50 after the wearing operation of the tire anti-skid device is finished, the tension force due to the rubber elasticity of the arm portion 42 of the tension band 40 is applied. It will be in a state of being. In the above-mentioned wearing operation, when the joint hook 45 attached to the tension band 40 is hooked on the joint portions 21 and 22 of the outer rope 20, it is not necessary to determine the order, and either joint portion should be hooked first. You may.

After the wearing, the mooring member 25 of the outer rope 20 is preferably tied together with the outer rope 20 so as not to be an obstacle when the vehicle travels. Regarding the difficulty of pulling out the tread member 10 to the outside of the tire 50 after binding of the inner rope, unless the tread member 10 is completely dropped inside the tire 50, it is troublesome. It never happens. However, if the length of the mooring member 25 of the outer rope 20 is excessively long, the tread member 10 may easily fall completely inside the tire 50. Therefore, the operation of pushing the tread member 10 inside the tire 50 should be performed carefully. It is desirable to take measures so that such a situation does not occur. However, if necessary, the maximum length of the mooring member 25 of the outer rope 20 should be set so that when the tread member 10 is pushed in, two joint portions 21, along the circumferential direction of the tire 50, are formed. The outer circumferential length of the outer rope 20 including the open intervals of 22 may be limited to a length that does not exceed the outer circumferential length of the tire 50.

In the tire anti-skid device of the above embodiment, the joint portion is provided at two places on the outer rope, but the outer rope is divided at two or more places, and the joint portion is provided at each divided place. Good. Also in the tension band of the tire anti-skid device in which the outer rope is provided with three or more joints, the same number of joint hooks as the respective joints are connected to the joints in the same manner as described above. Use the one that has been caulked and fixed to the hook retaining hole of the arm that corresponds to the position.

Further, the mooring member for connecting the joint portion of the outer rope is not necessarily limited to the joint portion at the divided portion of the outer rope as in the above-mentioned embodiment, and the joint portions of both ends of the outer rope are moored. The members may be connected by a member, and the joints at other divisions may be unconnected joints. The present invention is not limited to the tension band of the above embodiment, but may be a tension band in which only one joint hook is caulked and fixed. The outer rope of the tire anti-skid device using such a tension band is, for example, one in which both ends are bound to form a joint portion.

[0018]

[Effect of the device]

 As described above, according to the present invention, when the tire antiskid device is attached to the tire, it is necessary to take out and search for the joint hook for connecting the joint portion of the outer rope separately from the device. Instead, the joint hook prepared at the same time as the tension band can be hooked when the tension band is hooked to the outer rope. Not only is it simpler, there is no risk of losing the joint hook, and there is no need to prepare spare parts.
