Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a connector for a tire slipper.

(Prior Art) As shown in FIGS. 24 and 25, an anti-skid body of an automobile tire has a non-slip body 1 made of an elastic material such as rubber wrapped around an outer peripheral surface of the tire and slipped. The elastic ring 2 is connected to the outer end of the stopper body 1 in the width direction by engaging metal fittings 3 and the like, and the rope 4 is provided at the inner end of the anti-skid body 1 in the width transverse direction at appropriate intervals. And the loop portions 6 and 7 formed at both ends of the rope 4 are connected by a connecting tool 8, thereby connecting both ends in the longitudinal direction of the anti-skid main body 1 to each other.
There is one that is tightened on the outer peripheral surface of the tire.

However, the conventional connecting tool 8 is composed of a single metal rod as shown in FIG.
An annular portion 9 connected in a chain shape to the above, and a hook-shaped hook portion 10 that is detachably engaged with the other loop portion 7 are formed, and the hook portion 10 is simply bent in a U shape. And the hook part
The end portion of 10 and the annular portion 9 were largely separated from each other.

(Problems to be solved by the invention) Therefore, in the conventional case, when the vehicle suddenly starts on a snowy road or an icy road surface, the tire spins. Also, if the engine speed is increased in order to slip when climbing a hill, the tire will spin idle against the road surface. At this time, the loop portion 7 of the rope 4
And the connecting tool 8 come close to each other, and the loop portion 7
There was a case where the connecting tool 8 came off.

In view of the above problems of the present invention, it is an object of the present invention to prevent the connecting tool from being disengaged from the loop portion even when the tire spins.

(Means for Solving the Problem) The technical means of the present invention for solving this technical problem is to connect the widthwise ends of the anti-skid body 23 wound around the outer peripheral surface of the tire 16 at appropriate intervals. A loop 39, 40 which is formed at both ends of the rope 25 and which is a connecting tool for connecting the loops 39, 40 with each other and which is connected to one loop 39 of the rope 25 in a chain shape.
47 and a hook-shaped hook portion 48 that is insertably engaged with the other loop portion 40 in a detachable manner. On the side end, hook part 48
An extension part 55 is provided that extends to reach the annular part 47 in the direction of separation between the annular part 47 and the annular part 47, and a gap 56 into which the loop part 40 can be inserted is provided between the extension part 55 and the annular part 47. ,
The point is that it is formed in a direction orthogonal to the separating direction.

(Operation) Even if the loop portion 40 and the connecting tool 42 come close to each other as shown by the chain line in FIG.
The extension 55 can effectively prevent the connector 42 from coming off the loop portion 40. Further, when the hook portion 48 is connected to the loop portion 40, a part of the loop portion 40 may be inserted through the gap 56, and the hook portion 48 can be easily connected to the loop portion 40.

Further, the loop portions 39, 40 are connected to the inner end portions of the connecting portions 34, 35 by the engagement fittings 43 via the mounting holes 44 or the mounting holes 37. The outer ends of the connecting portions 34, 35 are connected to each other by an outer connecting fitting 45.

The connecting tool 42 is formed by bending a single metal rod as shown in FIGS. 1 and 2, and has an annular portion 47 connected to one loop portion 39 in a chain and the other. Hook-shaped hook portion 48 that is detachably engaged with the loop portion 40, and the attachment hole for the connecting portion 34.
An engagement portion 49 that is inserted into and engaged with 37 is formed. Then, at the end of the hook portion 48 opposite to the annular portion 47, the extension portion
55 is provided. The extension portion 55 is extended so as to reach the annular portion 47 in the separating direction (b) between the hook portion 48 and the annular portion 47, and the loop portion 40 is inserted between the extension portion 55 and the annular portion 47. Possible gaps 56 are formed in a direction orthogonal to the separating direction (b).

7 to 9 show other embodiments, respectively, and FIG. 7 shows an end portion 55a of the extension portion 55 having an annular portion for facilitating insertion engagement of the hook portion 48 with the loop portion 40. It is bent in a direction away from 47 (outward in the width direction of the anti-skid body 24).
FIG. 8 shows the winding direction of the annular portion 47 which is opposite to that in the case of FIGS. 1 and 7. In FIG. 9, a constricted portion 57 is provided in the middle of the hook portion 48 and the annular portion 47 and in the middle of the extension portion 55 in correspondence with each other.
