Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an attachment for a tightening band for a tire anti-skid device.

(Prior Art) Generally, when attaching the anti-skid device D to the tire B, as shown in FIG.
A ring-shaped rubber tightening band C is hooked onto _D1 , and the contraction force of this tightening band C ensures that the anti-slip device D is brought into close contact with the circumferential surface of the tire B.

The larger the contraction force of the tightening band C, the more the anti-slip device D
can be more securely attached to the tire B, but on the other hand, it requires more force to latch onto the latch hook D ₁ when it is mounted, making it difficult for women, elderly people, etc. to hook the hook D1. There was a problem that made it difficult.

As a solution to this problem,
There is a fitting A' disclosed by No. 40206.

As shown in FIG. 9, this conventional fixture A' is a rod-shaped body with a hook 4 in the middle and a fitting hole 5 in the head. 4 and the fitting hole 5 with the hook
While it is loosely fitted in D ₁ , use the head as a fulcrum to rotate it toward the outside of the tire, expand the tightening band C, and hook the unlatched portion to the latching hook D ₁ . It's summery.

(Problem to be Solved by the Invention) Incidentally, generally, the installation work of the tire anti-slip device D is often carried out in a place where the footing is unstable and slippery, such as on a snow-covered road surface in a mountainous area.

However, when trying to attach the tightening band C using the conventional attachment tool A' under such conditions, the rotational fulcrum of the attachment tool A' is set inside the tire diameter. Work had to be done crouching on the road, and not only did the workers' clothes get dirty with snow and mud, but there was also the risk of their hands and feet getting caught in the tires if the car skidded. Furthermore, since the fitting hole 5 is loosely fitted into the hook D ₁ , the rotational fulcrum is unstable and it is difficult to apply force, and this combined with the fact that the footing is slippery as mentioned above, makes the work extremely easy. Unfortunately, it was difficult to install, especially for weak women and elderly people.

The present invention was developed in view of the above-mentioned conventional circumstances, and its purpose is to set the rotational fulcrum of the mounting tool outside the tire diameter so that the tightening band can be hooked while standing. To provide a mounting tool which can extremely easily carry out the work of hooking a tightening band by making it possible to fix the rotational fulcrum in a more stable state.

(Means for solving the problem) In order to achieve the above purpose, the mounting tool of the present invention is
The tip of an operating lever whose base end serves as a grip is pivotally attached to the upper surface of a horizontally long flat support plate that curves in the circumferential direction of the tire, and a hook piece is provided at the tip in the middle of the operating lever. It is characterized in that the proximal ends of the provided hooking rods are pivotally connected.

(Function) According to the above-mentioned means, by attaching the support plate to the tire circumferential surface, the rotational fulcrum of the operating rod is set at the tire circumferential surface, and the operating rod can be rotated upward using this portion as the fulcrum. Then, the work of hooking the tightening band hooked on the hook piece at the tip of the hook rod onto the hook can be done while standing. Furthermore, since the support plate is shaped like an oblong flat plate that curves along the circumferential direction of the tire, the contact area of the support plate with the tire circumferential surface becomes large and the contact is made in a close manner. The movable fulcrum is reliably fixed in a stable state, and it becomes easier to apply force when rotating the operating rod.

(Example) Hereinafter, one example of the fixture according to the present invention will be described based on the drawings.

The fixture A is formed from a support plate 1, an operating rod 2, and a hook rod 3.

The support plate 1 is made of FRP, synthetic resin, rubber, metal, or other material and is integrally formed into a desired planar shape that curves along the circumferential surface of the tire B, and is closely attached to the circumferential surface of the tire B. It's becoming like that. In addition, there are left and right clamping pieces 1 on the upper surface approximately in the center.
1 is fixed upright.

The operating rod 2 is an elongated rod having a desired strength, and its one end 21 is pivotally connected to the clamping piece 11, and when the supporting plate 1 is attached to the circumferential surface of the tire B, it is attached to the shaft of the tire. extending parallel to the direction, and
It is rotatably supported in the vertical direction.

A grip portion 22 is formed at the other end of the operating rod 2, and a clamping piece 23 extending downward is integrally provided at a position spaced apart from one end 21 by a predetermined distance.

The hooking rod 3 has its base end pivotally connected to the clamping piece 23, and extends toward the center of the tire B with the support plate 1 attached to the circumferential surface of the tire B, and extends in the horizontal direction. Rotatably supported.

A hook piece 31 on which a tightening band C can be hooked is provided at the tip of the hook rod 3.

Below, a procedure for hooking the tightening band C to the hook _D1 using the fixture A configured as described above will be explained based on FIGS. 2 to 5.

First, after attaching the anti-slip device D to the tire B, the tightening band D is hooked to the hooks _D1 at a plurality of locations on the lower half of the circumferential surface of the tire B (see FIG. 4).

Next, after attaching the support plate 1 to the upper end portion of the circumferential surface of the tire B, the latching hook on the tightening band C is attached.
Hook the part that is not hooked to D ₁ onto the hook piece 31 (see Figure 2).

Then, rotate the operating rod 2 upward to pull the hooking rod 3 above the tire B, expand the tightening band C, and hook it onto the hook _D1 in the upper half of the circumference of the tire B ( (See Figure 3).

At this time, since the support plate 1 is attached to the circumferential surface of the tire B, the rotation operation of the operating rod 2 can be performed while standing. In addition, the support plate 1 is closely locked to the circumferential surface of the tire B, and its rotational fulcrum is securely fixed in a stable state, making it easier to apply force to rotate the operating rod, and making it easier for the feet to move. Able to work extremely efficiently even in unstable locations.

The above-mentioned hooking operation is performed sequentially for each hook D ₁ on which the tightening band C is not hooked, so that the tightening band C is hooked on all the hooks D ₁ and attached in a ring shape. At this point, the installation of the tightening band C is completed (see Fig. 5).

It should be noted that the tightening band that can be attached using the fixture of the present invention is not limited to the ring-shaped one shown in Figs. 4 and 5, but can also be used with other shapes as shown in Fig. 6, for example. It is.

The tightening band C' shown in Fig. 6 is formed by connecting an outer ring C' ₁ and an inner ring C' ₂ arranged concentrically by a connecting arm C' ₃ , and the inner and outer rings C' ₁ and C' The contraction force of ' ₂ allows the anti-slip device D to be brought into closer contact with the circumferential surface of the tire B.

This tightening band C' is attached in a ring shape by sequentially hooking the outer ring _C'1 to all the hooks _D1 in the same manner as described above. (See Figure 7).

In addition, in the present invention, the anti-slip device D to be used is not limited to the net type shown in the figure,
For example, a ladder-type tire anti-skid device, which has a plurality of anti-skid members extending across the width of the tire circumferential surface at equal intervals, and each anti-skid member is attached and fixed with a connecting rope, or various other devices. Can be used to attach tightening bands for tire anti-slip devices.

(Effects of the invention) Since the invention is constructed as explained above, it is now possible to rotate the operating rod upward and hook the tightening band onto the hook while standing. This eliminates the disadvantages of conventional products that require workers to work while crouching on the road, such as getting their clothes dirty while working, and the risk of hands, feet, etc. getting caught in the tires if the car skids.

In addition, since the support plate is shaped like an oblong flat plate that curves along the circumferential direction of the tire, the rotation fulcrum of the operating rod is reliably fixed in a stable state, and
It becomes easier to apply force when rotating the operating rod, and in combination with the fact that work can be done in a standing position as described above, work can be done extremely efficiently even in places where footing is unstable.

Therefore, it is not only possible to work extremely quickly and easily even in places where the footing is unstable and slippery, such as on a snow-covered road surface, but even if the user is a weak woman or elderly person, the work can be done easily. etc., it has many effects.
