Description

[Detailed Description of the Invention] This invention relates to an improvement of a clamping rod, which is a component of a tire chain mounting tool used when winding an anti-slip chain around an automobile tire.

Generally, when a car drives on snowy or icy roads, tire chains are wrapped around them to prevent them from skidding or slipping, but in this case it is extremely difficult to attach the chains to the car's tires. However, since it is time consuming and the working conditions are not good, it has been considered to use a conventional tire chain mounting tool.

This tire chain installation tool fixes one end of the chain to the tire, moves the car itself to wrap the chain around the tire, then attaches both ends of the chain to each other, and removes the tire chain installation tool from the tire to perform installation work. This greatly improves work efficiency.

Conventional tire chain mounting tools formed based on this idea often have a structure that clamps both the front and back sidewalls of the tire, but this device has the highest clamping ability among them, and also The present invention relates to a tire chain mounting tool in which a clamping rod is mounted and pivotally mounted in a frame body that has a good locking function to a wall, and the objective is to improve the clamping rod as one component of the tire chain mounting tool.

Conventionally, this type of tire chain mounting tool has a clamping rod with its end engaging portion pivoted inside a frame formed in a U-shape, a shape, or an L-shape, and the clamping rod is attached to the frame. A pressing rod or a pressing mechanism that slides along the back wall of the body arm pivots to clamp the sidewall of the tire, and the frame body is attached to the tire and the outside part of the frame body or the frame body is It is used by fixing the end connecting fitting of the chain by a pressing rod that is inserted into the outside part or a retaining rod attached to the pressing mechanism, and the clamping rod, which is one of the components, is a long rod. , because the distal end is pivotally attached to the shoulder of the frame body or the intersection area between the vertical and horizontal pieces, so there is no adjustment function to accommodate the size of the tire sidewall. The clamping rod has a length that corresponds to the sidewall of the tire to be clamped by drilling a large number of bearing holes in the frame body or the side of the frame, or it has a length that corresponds to the sidewall of the tire to be clamped, or it has a length that corresponds to the sidewall of the tire to be clamped. It was necessary to accommodate the size of the tire sidewall by drilling a bearing hole on the side of the intersection area and preparing several types of clamping rods with different lengths based on the bearing hole.

This invention was devised in view of these points, and its embodiment will be explained based on the drawings. Reference numeral 1 denotes a clamping rod, as shown in FIGS. is curved in a reversible shape, protruding hooking parts 3, 3' are formed on the front surface of the tip, a long hole 5 is bored on the back surface of the lower part 4, and the distal end 7 is bent into an L-shape. is forming. Reference numeral 8 denotes an engaging rod, and as shown in FIGS. 1 to 3, the engaging portion 1 has a screw hole 9 in the upper part and a pair of multi-shaft holes 10 and 10' in the lower part.
1, 11'. Numeral 12 is a screw that passes through the elongated hole 5 of the engaging rod 8 and screws the clamping rod 1 and the engaging rod 8 into the threaded hole 9 of the clamping rod 1, thereby connecting the two rod bodies. The screw 12 can be slid to adjust the overall length by loosening and tightening the clamping rod 1 and the engaging rod 8.

In this way, this device has a protruding front surface, a curved upper back surface, a long hole in the lower back surface, and an L-shaped distal end. A clamping rod and an engaging rod having a screw hole bored in the upper part and a multiaxial hole bored in the lower part are connected by a screw, and the said clamping rod and the engaging rod are slid by loosening and tightening the screw. Therefore, if this is used to construct a tire chain mounting tool, as shown in FIGS. By unscrewing the screw, sliding the clamping rod 1 to fit it to the sidewall of the tire 16 to be clamped, and then conversely tightening the screw 12, the sidewall of the tire 16 can be secured with a simple operation. By determining the length that corresponds to the size of the tire, you can attach it to fit the tire.
