Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tightening band that prevents loosening of a tire chain that is wrapped around a tire of a vehicle to prevent slips on icy and snowy roads.

[Prior art and its problems] A tire chain consists of two side chains provided along both sides of a tire, and a plurality of cross chains bridged between the side chains at a predetermined distance from each other. Wrapping around the tire is done by engaging a hook provided at one end of the side chain with any one chain ring on the other end, but it is difficult to wrap the tire chain without slack, and it takes a considerable amount of time. Requires skill.

If the tire chain is loosely wrapped around the tire, there is a risk that the tire chain will come into contact with the vehicle body while driving, causing impact noise, damaging the vehicle body, or causing the tire chain to fall off. Therefore, to prevent the tire chain from loosening, a ring-shaped tightening band is used on the outer side chain to tighten it. However, conventional tightening bands are made of rubber or spring coils formed into a ring shape, and there is a problem in that the tire chain often loosens during driving.

The tire chain loosens while the vehicle is running because the tightening band stretches due to the centrifugal force acting on the tire chain.If the tightening force and elasticity of the tightening band are weak, the tire chain loosens while the vehicle is running. If the elasticity is strong, it can prevent the tire chain from loosening, but it is difficult to install. Tire chains are wrapped manually on icy and snowy roads, etc., so there is a natural limit to how strong the elasticity of the tightening band can be handled.In order to make it easier to handle, the elasticity of the tightening band should be weaker. good. Therefore, measures have been taken to reinforce the tightening band using a cross or radial tightening belt.

However, even when a tightening belt is used, the tightening band has some parts where the tension is tightened relatively strongly and other parts where the tension is loosely tightened.Moreover, all known tightening belts extend from the center point of the tightening band to the outer ring. It has a cross-linked or radial cross-linked structure, so the tensile force applied to the tightening band and the tightening belt during high-speed running is applied to the tightening belt bridged diagonally passing through the center point, and is applied to other tightening belts. The particles were not dispersed onto the belt, and there was a risk of loosening of the tightening band or breaking of the tightening belt.

[Means for solving the problem] The present invention provides a safe tightening band that prevents the tire chain from loosening during driving.
To explain with reference to the drawings, FIG. 1 is a front view showing an embodiment, which is composed of an outer ring part 1 made of rubber or synthetic resin, an inner ring belt part 2, and a crosslinked belt part 3, and is made of a crosslinked belt part. 3 is longer than the straight line distance between the outer ring part 1 and the inner ring belt part 2 and is bridged at an angle so that its extension direction does not intersect the center points of the outer ring part 1 and the inner ring belt part 2.

Fig. 2 is a front view showing the state of use, in which the tire chain 6 wrapped around the tire 5 is engaged with the tightening band by the hook 4 and tightened, and the extension line of the bridge belt section 3 is directed in the direction of the wheel center point. They are installed at an angle without intersecting.

[Operations and Effects] Since the present invention has the above-mentioned configuration, the elasticity of the tightening belt can be made relatively weak, making it easier to wrap the tire chain when attaching the chain to the wheel. This prevents the tire chain from loosening due to centrifugal force stretching the tightening band while driving, and prevents the tire chain from coming into contact with the vehicle body, causing impact noise, damaging the vehicle body, or falling off. It is possible to provide a safe tire chain without the risk of
