Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a tire chain mounting aid.

``Prior Art'' Tire chains are indispensable for driving a car when there is snow or ice on the road.
Tire chains can be installed using two methods: spreading the tire chain in front or behind the drive wheel and moving the car to install it; or by locking a jack at a designated position on the car body and tightening the jack, then attaching the tire to the top of the tire on the drive wheel. Cover the tire chain with the tire chain, and lock the hook provided at one end of the tire chain to the link at the other end of the tire chain from the inside of the tire chain, that is, from the vehicle body side. After installing the tire chain, jack down. There is a jack up method in which the jack is removed after the tire is in contact with the ground.

``Problem that the invention aims to solve'' The mobile mounting method is surprisingly time consuming for beginners and women because the tires may not be placed properly on the tire chain, and the vehicle body may be damaged due to incorrect tire and chain mounting. There are many problems involving the tire chain at the rear. In addition, the jack-up method requires time and effort to engage and disengage the jack from the vehicle body, and it is difficult to use the jack in sloped, soft or narrow places, and the engagement between the jack and the vehicle body is difficult. If it is not secure, the jack may come off, which is very dangerous.

``Means for solving the problem'' A hook rod with a hook formed at the tip to be hooked to a connecting link hanging down on one side of the vehicle body of a ladder-shaped tire chain that is placed over the top of the drive wheel, and a connecting link. Throw the hook rod that is locked to the tire chain connecting link that hangs down on the other side of the car body, and then pull it out and hook it to the tire chain connecting link that hangs down on the other road side. A short hook rod having a hook formed at the tip thereof is rotatably connected to the rod, and further a short hook rod having a hook formed at the tip for locking to a non-slip link placed on the tire tread is freely connected to the rod, or Instead, the purpose is to attach the tire chain to the drive wheel quickly, easily, and reliably by rotatably connecting it to the base of the hook rod.

"Function" Therefore, according to this invention, if it is a FF vehicle, the front wheels
If it is an FR car, put a ladder-shaped tire chain over the rear wheel from above, lock the hook of one hook rod to one of the connecting links hanging down on one side of the car body, and attach it to the other side of the car body. A connection in which the hook of the short hook rod is locked to the connection link or the non-slip link by throwing it to the side of the connecting link that is hanging down, and then pulling out the connecting link slightly, and the hook of the other hook rod is hanging down to the road side. At the same time, the other short hook rod is locked to one of the non-slip links or one of the connecting links that rests on the tire tread, and then the car is moved slightly and the other short hook rod is placed on the tire chain. After attaching the tire chain to the drive wheel by placing the connecting hook on the side of the tire and attaching the connecting hook to the end of the link on the vehicle body side and the road side, connect the hook of the foot rod and the link. and the lock between the short hook rod and the non-slip link or connecting link.

``Example'' Below, an example of the present invention will be explained based on the drawings.As shown in Figs. A ladder-shaped tire chain 2 is installed above the rear drive wheel 1.
Cover with the anti-slip links 2a that make up the tire, place the connecting links 2b, 2b along the side of the tire, let the four open ends hang down on the front and back of the vehicle body side and the front and rear of the road side, and A hook rod 3 is formed with a hook 3a at the tip that locks to the third connecting link 2b counting from the open end of the hook rod 3, and the hook rod 3, which is locked to one of the connecting links 2b on the vehicle body side, is attached to the vehicle body. A hook 4 is thrown with the connecting link 2b hanging down on the other side as a target, and then pulled out slightly and locked to one of the connecting links 2b on the other side.
The base end of a hook rod 4 having a tip a and the base end of the hook rod 3 are rotatably connected by a connecting rod 5. A short hook rod 6 with a hook 6a formed at its tip is movably attached to the connecting rod 5, and the hook 6a is attached to one of the anti-slip links 2a or one of the connecting links 2b constituting the tire chain 2. It is locked so that the connecting rod 5 comes into pressure contact with the tire tread surface 1a. As another embodiment, as shown in FIGS. 4 and 5, the base end of the short hook rod 6 is rotatably engaged with the base ends of the hook rods 3 and 4, and the hook rods 3 and 4 are connected. It is rotatably engaged with the connecting rod 5 via the ring 7. In FIG. 8, a chain band 9 8 is an S-shaped locking metal fitting, one end of which is rotatably connected to one end of the connecting link 2b, and the other connecting link 2b that abuts against the connecting link 2b. After locking the other end, turn it over,
The other end of the tire chain 2 is first connected to the vehicle body side by locking the other end to the locking link 9a which is integrally fixed in the direction orthogonal to the connecting link 2b to which the locking metal fitting 9 is connected, and then the road side is connected. This is a known locking fitting that connects the In the case of double tires, insert a long stick or a telescopic stick into the gap between the double tires, extend the hook rod 3, the connecting rod 5, and the hook rod 4 in a straight line, and attach the long rod to the hook 4a of the hook rod 4. The hook 3a of the hook rod 3 is positioned near the connecting link 2b hanging inside the double tire by locking the tip of the rod and pulling out the long rod, and then locking it on one of the connecting links 2b, and then Pull out rods 4 and 3. After pulling it out, the hook 6a of the short hook rod 6 is locked to either the connecting link 2b or the non-slip link 2a, then the hook 4a of the hook rod 4 is locked to the connecting link 2b, and then the other short hook rod 6 is locked. The car is moved by locking the hook 6a to either the connecting link 2b or the non-slip link 2a. Incidentally, since tires have different widths, the present invention can be applied to any type of tire by adjusting the length of the connecting rod 5 according to the width.

"Effect of the invention" Since the invention is constructed in this manner, the tire chain 2 is placed over the tire tread surface 1a of the drive wheel 1, and the hook 3a of the hook rod 3 is secured to one of the connecting links 2b on the vehicle body side. Throw the hook rod 3 to the vehicle body side in front or behind the drive wheel 1, and then pull it out. Lock the hook 4a to the hook 4a, and then lock the hook 6a of the short hook rod 6
The tire chain 2 is temporarily attached to the drive wheel 1 by locking it to the anti-slip link 2a or the connecting link 2b of the tire chain 2 and bringing the connecting rod 5 into pressure contact with the tire tread 1a. Next, move the car slightly and position the ends of the connecting links 2b that are butting together in the lateral direction of the drive wheel 1, and position the connecting links 2b on the vehicle body side.
First, connect the connecting links 2b on the road side, then connect the connecting links 2b on the road side, and then connect the chain band 8 on the road side side of the tire.
..., and finally remove the foot rods 3 and 4 and the short foot rod 6 to complete the tire chain installation. Since no skill is required to mount the drive wheel, and there is no need for the trouble of attaching and disengaging the jacks to the vehicle body frame one by one as in the jack-up method, anyone can easily and quickly set up the tire chain without any skill. can be installed securely.

As described above, the present invention is a useful device that has a simple structure, is easy to manufacture, and is inexpensive.
