Description

[Detailed description of the invention] (Industrial application field) This invention is a latching fitting for a tire slip prevention device, which has a hook portion formed at the tip and a fastening portion formed at the base end. The present invention relates to a latching fitting which is provided by caulking and fixing a latching part to a fitting part of a non-metallic tire skid stopper main body, and a rubber band or the like for tightening is latched to the hook part at the tip of the latching fitting.

(Prior art and its problems) Conventionally, there is a hanging metal fitting of this type described in Japanese Utility Model Application Publication No. 109806/1983, in which both the hook part and the fastening part have the same wide shape. However, the shape of the fastening portion was not formed along the shape of the metal fitting attachment portion of the tire anti-slip device body.

Therefore, for example, in the case where the attachment part has an arc shape, even if the fastening part is wide, the contact area is very small at two points on both sides of the fastening part. Because the tensile force applied to the fastening part was concentrated locally, the fastening part was likely to dig into the mounting part, and if a shockingly large tensile force was applied to the metal fitting, the mounting part would be cut off. There was a fear that this would happen.

On the other hand, the hook portion is used to hang a small diameter rubber band, and since the rubber band has strong elasticity, a large amount of effort is required when hooking the hook if it is wide and has the same width as the fastening portion.

(Technical Problem) The technical problem of the present invention is to prevent the tensile force applied to the latch fitting from being partially concentrated on the metal fitting attachment part of the anti-slip device body, and to improve the workability of hooking the rubber band. The aim is to improve the

(Means for solving the technical problems) The means taken by the present invention to solve the above-mentioned technical problems is to form a hook part at the tip and attach it to the metal attachment part of the tire anti-slip device body at the base end. A latching fitting for a tire anti-slip device that is provided with a fastening portion for latching and fixing by caulking, the hook portion is formed into a narrow shape, and the fastening portion is attached to a metal fitting attachment portion of the main body of the tire non-slip device. The fixing part is formed in a wide and parallel shape, and holding parts having a circular cross section are provided around both side edges of the fastening part.

(Function) According to the above means, when the fastening part of the latch fitting is latched and fixed by caulking to the metal fitting part of the tire anti-slip device body, the fastening part makes wide contact along the shape of the metal fitting part. In addition to being fixed in this state, the holding portions having a circular cross section on both side edges of the fastening portion prevent damage.

When a tensile force is applied to the above-mentioned latching fitting, this tensile force is widely distributed and applied to the portion of the fitting attaching portion that is in contact with the fastening portion.

Also, since the hook part is narrow, it can be installed smoothly when hooking a rubber band.

(Effects) Since the present invention is as described above, it is possible to receive the tensile force applied to the latching fitting along the shape of the fitting part of the anti-slip fitting and widely distributed, and furthermore, it is possible to receive the tensile force applied to the latching fitting in a wide distribution along the shape of the fitting part of the anti-slip fitting. The holding part with a circular cross section on the edge prevents scratches, so the fastening part of the latching metal part will not dig into the metal fitting part, and if a large tensile force is applied to the latching metal fitting part, the metal fitting part will be damaged. There is no possibility that the wire will be disconnected.

Furthermore, since the hook part has a narrow shape, the work of hooking the rubber band is smooth and workability is good.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

The latch B shown in FIG.
A fastening part 1a is formed to be hooked onto the metal fitting attachment part a of A' and fixed by caulking, and a hook part 1b is integrally formed on the tip side of the metal fitting main body 1.

The fastening portion 1a is formed by bending a wide steel plate having a cross-sectional shape as shown in FIG. The hook part 1b is attached to the above-mentioned fastening part 1.
It is formed together with a from a single steel plate, or it is formed by bending a wire rod into a hook shape and welding it to the tip side of the fastening part 1a, and it is formed in a narrow shape.

As shown in FIG. 5, the fastening part 1a has holding parts 1c, 1c each having a circular cross section on both side edges.
As a result, both edges of the fastening part 1a are rounded to prevent the metal fitting part a, which is fixed by caulking the fastening part 1a, from being damaged by the both sides of the fastening part 1a during use. It is.

The latching fitting B having the above structure has, for example, a net-type anti-slip fitting main body A′ as shown in FIG. And the tightening rope 2 is attached to the hook part 1b...
The rubber band 3 for fixing and tightening is latched.

When installing, as shown in Fig. 6, the anti-slip device body is made by covering a core material 4 made of high tensile strength synthetic fiber with a covering material 5 made of rubber or synthetic resin.
The fastening part 1a is hooked onto the metal fitting mounting parts a and a' of A' and then fixed by caulking.

The fastening part 1a fixed by caulking is attached to the metal fitting part a,
It is fixed in a state where it is wrapped around a', and makes wide contact with the shape of the metal fitting attachment parts a and a'.

When a tensile force is applied to the hook part 1b in the usage condition shown in FIG. Since the holding parts 1c, 1c on both side edges of the fastening part 1a are largely rounded, the covering material 5 of the metal fitting attachment parts a, a' will not be damaged.

In addition, the latch fitting _B2 shown in FIG.
a' is formed into an arc shape, and by doing so, when the metal fitting attachment parts a and a' have an arcuate shape, the fastening part 1a' is formed in the metal fitting attachment part a,
It can be fastened along the arc of a', and as in the above example, both side edges are provided with holding parts 1c, so the both edges of the fastening part 1a can be prevented from strongly digging into the fitting mounting parts a and a'. It can be prevented.
