Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to an auxiliary tool used when attaching tire chains to automobile tires.

[Prior Art] When attaching tire chains to the tires of a car during snowfall, a pair of tire chains are laid on the ground so as to be spaced apart from each other, and then the car is moved to attach both tires to the pair of tires. The tire chain is placed on top of the tire chain, and in this state, the tire chain is wrapped around the tire, and both ends of the tire chain are locked by a locking member.

[Problems to be Solved by the Invention] However, when attaching a tire chain to a tire as described above, the tire comes into direct contact with the ground, so the gap between the tire and the ground, which is the mounting work space, becomes narrow. Put it away, wrap the tire chain around the tire,
There was a problem in that the installation work was difficult.

Further, at this time, a part of the tire chain is pinched between the tire and the ground, so if the tire is not placed on the tire chain at an appropriate position, the tire chain cannot be shifted.

Therefore, there was also a problem in that it was difficult to reliably attach this tire chain to a tire.

An object of the present invention is to make it possible to increase the space for installing tires by separating the tires from the ground, thereby making it possible to easily perform the installation work of tire chains, and also to make it possible to shift the tire chains during the installation work. To provide a tire chain attachment aid that can reliably attach the chain to a tire.

[Means for Solving the Problems] Therefore, in order to achieve the above object, the present invention provides a tire chain consisting of a plurality of working parts installed side by side and a connecting part connecting both sides of each working part to a tire chain of an automobile. an auxiliary tool used when mounting the tire on the vehicle, including a mounting surface on which the tire can be mounted while being spaced from the ground, an inclined surface on which the tire rolls from the ground to the mounting surface; The gist of the present invention is to provide a tire chain mounting aid that is provided with a recess that opens in the mounting surface so as to accommodate a part of the working part of the tire chain that is mounted on the tire.

Further, it is preferable to provide a protrusion on the mounting surface to prevent the tire from slipping.

[Operation] When installing a tire chain, the installation aid is placed on the ground, and the tire chain is laid on the ground with a part of the working part of the tire chain accommodated in the recess. When a car tire is placed on the mounting surface via the inclined surface, the tire is separated from the ground. At this time, since a part of the working part of the tire chain is housed in the recess and is spaced apart from the tire, the load of the tire is not applied to the working part. Therefore, it is possible to shift the tire chain.

Further, when a protrusion is provided on the slope, the tire is prevented from slipping when rolling on the slope.

[Example] Hereinafter, an example in which the present invention is embodied in a mounting aid for a ladder-type tire chain will be described with reference to FIGS. 1 to 3.

As shown in Figure 1.3, the ladder-shaped tire chain 1
A plurality of acting parts 2 are arranged apart from each other so as to be parallel to each other, and each acting part 2 is arranged parallel to each other.
A pair of connecting portions 3 connect both ends of the connecting portion 3. Both of the acting portion 2 and the connecting portion 3 are formed by connecting a large number of ring-shaped chain members 4 in a straight line.

As shown in Fig. 1.2, the mounting aid of this embodiment (hereinafter referred to as the aid) used when mounting the tire chain 1 is made of synthetic resin, and its front end (left end in Fig. 2) is directed downward. It has an elongated, roughly sloping shape. As shown in FIG. 3, this auxiliary tool is formed so that the width from left to right (up and down in the figure) is smaller than the length A of the action part 2 of the tire chain 1. In addition, as shown in FIG.
is integrally formed, and the movement of this auxiliary tool in the front and back (left and right in the figure) direction when it is placed on the ground G is restricted.

The upper surface of the auxiliary tool is a mounting surface 6 on which an automobile tire T is placed, and a recess 7 extending in the left-right direction is formed at the center in the front-rear direction.

This recess 7 is open at the upper part of both left and right side surfaces 8 of the auxiliary tool, and the depth w of the recess 7 is as shown in FIG.
l and the longitudinal width w2 are formed to be larger than the width d of the chain member 40 of the tire chain 1, and it is possible to accommodate a part of one working part 2 in the tire chain 1.

On the mounting surface 6 excluding the inclined surface 9 and the recess 7 of the front part of the auxiliary tool, a plurality of protrusions 1 extending in the left-right direction are provided.
0 is integrally formed, and prevents the tire T from slipping when the tire T rolls on the slope 9 to get on the mounting surface 6 from the ground G, and also prevents the tire T from slipping. When placed on the mounting surface 6, it is prevented from slipping thereon.

Next, how to use the auxiliary tool configured as described above will be explained.

When attaching tire chains 1 to tires T during snowy conditions, prepare a pair of tire chains 1 and auxiliary devices, and attach them so that the inclined surfaces 9 of both auxiliary devices face the outer peripheral surfaces of both tires T of the automobile. Place the ingredients on the ground G while separating them from each other.

Then, the connecting portion 3 of each tire chain 1 is spaced outward from both left and right side surfaces 8 of the auxiliary tool, and the tire chain 1
Lay both tire chains 1 on the ground G with one working part 2 at the end accommodated in the recess 7 of each of the auxiliary tools.

Next, the car is moved and each tire T is placed on the mounting surface 6. In this embodiment, since the inclined surface 9 is formed at the front part of the auxiliary tool, each tire T can smoothly roll from the ground G to the mounting surface 6 thereof. Moreover, since a plurality of protrusions 10 extending in the left-right direction are formed on this inclined surface 9,
Even when snow adheres to the slope 9 or the outer peripheral surface of the tire T, the tire T can be reliably rolled without slipping.

When the tire T moves above the recess 7 of the i-face 6, the second
As shown in the figure, a part of the outer circumferential surface of the tire T enters into the recess 7 and comes into contact with the opening edge 7a of the recess 7, so that rolling of the tire T is restricted.

Further, since the mounting surface 6 excluding the recess 7 is integrally formed with a protrusion 10 like the inclined surface 9, the tire T is less prone to slipping than in the case where the protrusion 10 is not provided.

When the tire T is thus placed on the mounting surface 6, the tire T is separated upward from the ground G, so that the mounting work space between the two becomes large. Therefore, by using the auxiliary tool of this embodiment, it is possible to move the hand widely within the mounting work space, and unlike the prior art which does not use this auxiliary tool, the task of mounting the tire chain L on the tire T becomes easier.

Furthermore, when the tire T is placed on the mounting surface 6, the tire T does not come into contact with the acting part 2 of the tire chain 1 housed in the recess 7, and no load is applied thereto. It can be shifted within the recess 7 in the front-rear direction and left-right direction. Therefore, the tire chain 1 can be reliably attached to the tire T.

Incidentally, the auxiliary tool of this embodiment can also be used as a transportation stop even when the tire chain 1 is not attached to the tire T.

It should be noted that the present invention is not limited to the configuration of the above-mentioned embodiments, and can be modified and embodied as desired without departing from the spirit of the invention, for example, as described below.

(1) In the above embodiments, the auxiliary tool was made of synthetic resin, but it may also be made of wood or metal.

(2) In the embodiment described above, the recess 7 is formed to extend in the left-right direction of the auxiliary tool, but as shown in FIG. 4, it may be formed to extend in the left-right and front-rear directions, that is, in a planar cross shape. In this way, it can be used not only when attaching a ladder type tire chain but also when attaching a hexagonal type tire chain 1 or the like.

(3) In the above embodiment, the protrusion 1 extending in the width direction as a protrusion
0 is formed, but this may be replaced with a protrusion.

(4) The auxiliary tool of the present invention can also be used when attaching a tire chain to a double tire such as a trunk.

In this case, the inner tire T of the double tires is placed on the mounting surface 6 in the same manner as in the previous embodiment, and the tire chain 1 is attached to the outer tire T in this state.

[Effects of the Invention] Since the present invention is configured as described above, it has the following effects.

Since the tire can be moved away from the ground, it is not only easier to attach the tire chain to the tire (also, it is possible to shift the tire chain when attaching it, making it possible to securely wrap it around the tire). can.

Also, if you install a protrusion on a slope, it will ensure that the tires do not slip! 3! It can be moved onto the surface.
