Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting device for a tire chain used when mounting a tire chain on an automobile tire.

[0002]

2. Description of the Related Art Since the mounting operation of a tire chain must be performed under severe conditions of extreme cold (sometimes mixed with snowstorm), the mounting operation must be performed easily and in a short time. It is desired to do.

[0003] By the way, when a tire chain is mounted on a tire of an automobile, conventionally, a method shown in FIG.
Alternatively, the method shown in FIGS. 7 and 8 is performed. still,
As shown in FIGS. 6 to 8, a tire chain 10 for a heavy-duty vehicle (for example, for a heavy-duty truck) has strength and anti-slip performance as shown in FIGS.
A ladder-like structure having a large number of non-slip lines 15, 15... Interposed at a predetermined interval between them is employed, but the tire chain 10 composed of such a chain has a considerable weight.

[0004] The tire chain mounting method shown in FIG. 6 is performed as follows. First, the tire chain 10 is placed on the upper part of the tire 6, and each end in the length direction of the tire chain (each end indicated by reference numerals 13 and 14) is hung down and forward of the tire 6. If, before this, the wheels (tires 6) are previously mounted on the mounting table A and the lower surfaces of the tires are lifted off the ground, the working space below the tires is increased. Next, in the illustrated example, the rear end 14 of the left hanging portion of the tire chain 10 is turned around the rear side of the tire 6 to lock the rear hook 13 at the end 14, and then the left front side The end 14 is pulled to the right to lock the front hook 13 to the end 14.

In the tire chain mounting method shown in FIG. 6, the operation of placing the tire chain 10 on the upper portion of the tire 6 can be performed relatively easily because the hand can be inserted between the tire 6 and the tire cover 7. Work. However, in the case of FIG. 6, when the hook 13 is locked to the end portion 14 on the rear side, it is necessary to insert a hand from the near side to perform the operation at the rear side position closer to the lower part of the tire 6, and Since the hook locking position is an invisible place on the back side of the tire 6, the locking operation is extremely difficult, and the mounting operation of the tire chain requires a long time. In particular, a large-diameter and wide tire 6 such as a large car has a tire chain 10.
When the vehicle is mounted, the hand cannot be turned around to the locking position on the rear side of the tire, and the mounting method shown in FIG. 6 cannot be adopted as it is. Also, in the case of FIG.
In addition to the above, it is necessary to prepare the tire 6 on the mounting table A and to collect the mounting table by removing the tire 6 from the mounting table A after mounting the tire chain.

In the tire chain mounting method shown in FIGS. 7 and 8, the tire chain 10 is first laid on the ground close to the tire 6 to be mounted in the running direction of the automobile. . Then, the vehicle is slightly moved to the tire chain 10 side, and the tire 6 is mounted on one end side (right side in the illustrated example) of the tire chain 10 as shown in FIG. Next, the other end side (left side) of the tire chain 10 is wound around the upper part of the tire 6 as shown in FIG.
The hooks 13 attached to one end of each of the side chains 11 are engaged with the other ends 14 of each of the side chains 11.

By the way, in the conventional method shown in FIGS. 7 and 8, the operation of connecting the end portions of the side chains 11, 11, which is the last step, can be performed in a relatively extra space on the side of the tire 6. So it is relatively easy. However, before winding the tire chain 10 in the state of FIG.
As shown in FIG. 7, it is necessary to put the tire 6 on one end side of the tire chain 10, and at this time, the tire 6 must be placed exactly on the center of the tire chain 10 in the width direction. That is, the tire chain 1 on which the tire 6 is extended.
After riding on zero, the position of the tire chain 10 cannot be corrected because the tire 6 steps on the non-slip line 15. In order to put the tire 6 at the center position in the width direction of the tire chain 10, first, the tire chain 10
It is necessary to spread the tires precisely at the exact position near the tires.However, in the chain-type tire chain, the bend is freely bent at each chain link, and the ground surface is often uneven due to snow. It takes a great deal of time to successfully deploy on a computer. Furthermore, even if the tire chain 10 is expanded in an appropriate state, when the automobile is moved to put the tire 6 on the tire chain 10, the rotation of the tire 6 causes the tire chain that has been expanded in an appropriate angle to be positioned. In some cases, the tire chain may need to be re-started from the tire chain extension work. Also, from the state of FIG. 7, the other end side of the tire chain 10 (reference numeral 13 side)
When the tire is wound on the tire 6, the tire chain 10
It is necessary to wind the tire chain in a tensioned state, but the tire chain has a considerable weight, and especially in the vicinity of the symbol B in FIG. 8, the tire chain is easily loosened due to the weight of the tire chain. When the antiskid ropes 15, 15,... Enter the groove on the outer periphery of the tire, the tire chain cannot be tensioned even if the front end side of the chain (reference numeral 13 side) is pulled, and the winding work of the tire chain 10 is considerably difficult. It is difficult. As described above, in the tire chain mounting method shown in FIGS. 7 and 8, the operation is difficult and requires a long time before the winding state shown in FIG. 8 is obtained.

[0010] That is, the tire chain mounting device of the present invention has a flat U-shape formed by connecting the base ends of two mutually parallel rods at a connection spanning the width of the tire. Uses the wearing equipment body. Also, at the distal end of each rod portion, a locking portion that can be locked to each side of the tire chain is formed, and a string of a predetermined length is connected to the base end side of the mounting device body, A hook that can be locked in place on the tire chain is attached to the tip of the string.

The mounting device for a tire chain according to the present invention, when mounting the tire chain on the tire, places the tire chain from above the easy-to-operate tire and works when connecting the left and right ends of the tire chain. It is intended to be able to be performed on the side of a simple tire.

The attachment body can be made of an appropriate material such as plastic or metal, or hard rubber or carbon. In addition, when the attachment body is formed of plastic or metal, a simple structure in which a simple round bar or a narrow plate material is bent in a plane U shape can be adopted. Further, the attachment main body may be formed of a pipe material.

The distance between the rods and the length of the rods are appropriately determined according to the tire width and tire diameter for various types of vehicles (light cars, ordinary passenger cars, large trucks, etc.). still,
The interval between the rods is designed to be slightly larger (for example, about 10 mm larger) than the tire width to be used, and the length of the rod is preferably designed to be, for example, about 50 to 90% of the tire diameter.
In addition, in this mounting device body, the length between the rod portions can be adjusted by making the length of the connecting portion adjustable, and the length of each rod portion can be adjusted by making the length of each rod portion adjustable. can do. In that case, one mounting tool body can be applied to a plurality of tires having different sizes.

The locking portion at the tip of each rod may be hook-shaped or a thin rod bent downward into a hook shape. When a chain is used as a side chain of a tire chain, the locking portion is locked to a chain ring of the side chain.

The string at the base end of the wearing tool body may be an ordinary string which does not expand or contract, but is preferably an elastic string such as a rubber string. Note that the base end of the cord may be attached to the connecting portion of the wearing tool main body.

The tire chain mounting device of the present invention is used as follows when mounting a tire chain on a tire. First, the tire chain is placed on the tire. At this time, the tire chain is stretched in the width direction with the vicinity of the center in the length direction of the tire chain located near the top of the tire. In this state, each end of the tire chain in the length direction hangs down at a position near each left and right single end of the tire in a state of contacting or approaching the ground. Next, the rod end of the mounting tool is inserted from one side (for example, the right side) of the tire so as to straddle the inner and outer side surfaces of the tire, and each locking portion of the rod end is inserted. The chain hanging portion on the front side (for example, the left side) is locked at an appropriate position near each end of the chain. Then, raise the base end side of the wearing tool body upward until the connecting portion contacts the tire outer surface,
When the hook at the leading end of the string is locked in a proper position in the chain (for example, a non-slip line between both side chains) in a tensioned state, the setting of the attachment is completed. In this state, the chain wrapping range from the portion where the locking portion of each rod portion is locked to the portion where the hook of the string tip is locked in the tire chain is tensioned in a state of being pressed against the tire outer peripheral surface. Therefore, even if the tire (wheel) is rolled until the wearing tool is displaced from the lower position to the side position, the winding posture of the tire chain does not collapse. Note that, even when a non-stretchable cord is used as the attachment device, the portion of the tire chain that is wound around the outer peripheral surface of the tire is not deformed. Next, the tire is moved at an angle of 90 to the side where the connecting portion side of the wearing tool body moves upward.
The vehicle is rolled by about 〜 ° to 110 ° (moving the vehicle forward or backward by a slight distance) and stopped with the wearing tool positioned on the side of the tire. Then, in this state, the wearing tool is removed from the tire chain, and at the tire side position, the rear ends of the tire chain and the front ends are connected to each other, and finally, a fastening band is attached to the tire chain. The mounting work of the tire chain is completed.
