Description

[Detailed explanation of the idea] The present invention relates to a tire anti-slip fitting.

When driving on snowy, icy or muddy roads,
In order to prevent wheels from slipping, as is well known, a method of wrapping a chain around the tire surface is used.
Conventionally, this type of tire chain has been installed so as to surround the tire in a mesh pattern over the entire circumferential surface of the tire. To do this, when installing a tire chain, first spread the tire chain in front of the drive wheel, place the tire surface of the drive wheel on it, secure the end of the chain using the tire wheel hole, and then attach the tire chain to the front of the drive wheel. The method used was to move the chain forward a little and wrap the chain around the tire surface, fixing the other end and middle part of the chain.

Therefore, conventionally, this type of tire chain is troublesome to attach and detach from the wheels, and even when approaching snowy, icy or muddy roads, the chain may be neglected, resulting in unexpected accidents. Something happened.

The purpose of this invention is to use a metal piece with claws that has an excellent anti-slip effect that cannot be expected from conventional chains, and which can be attached to a part of the tire surface of the drive wheel to provide sufficient anti-slip properties. Furthermore, by partially attaching the tire to the tire surface, the attaching operation can be carried out extremely easily.

The illustrated embodiment will be described in detail below.

FIG. 1 is a diagram of a tire installed state showing one embodiment of the metal fitting of the present invention, in which several metal pieces 1 made of iron plates etc. are connected, and a band 2 and a tightening metal fitting 3 are attached to both ends of the metal pieces 1 that are connected. Install this band 2
is inserted through the hole 4 of the tire wheel and is firmly fixed to the tightening fitting 3.

As shown in FIG. 2, this metal piece 1 has its both edges folded up to form a claw portion 5. Furthermore, the tip of this claw portion 5 is formed into a serrated shape to prevent it from touching frozen roads. The bite has been improved. In addition, in order to connect the metal pieces 1 so that they can be bent at the connecting part, a chain-shaped metal ring 6 is attached by loosely passing through small holes 7, 7 made at the ends of the metal pieces 1. be.

FIG. 3 is a perspective view showing an embodiment of the fastening fitting in the fitting of the present invention, and shows the shaft support 9 of the fitting main body 8.
One end of a band fixing rod 11 and one end of an operating rod 12 are each rotatably attached to a shaft 10 inserted through the shaft 10 .

A band holding piece 13 is provided at the free end of the band fixing rod 11, and the band 2 passing through the band through hole 14 at the tip of the main body 8 is suspended as shown by the chain line in FIG. 3. It is designed to be fixed. On the other hand, in the operating rod 12, a drawing rod 17, whose both ends are passed through the small holes 7, 7 at the ends of the metal piece 1 and bent, is rotatably inserted into the shaft hole 16 bored in the side of the operating rod 12. It's through.

In the figure, reference numeral 18 denotes a tongue piece formed by extending one end of the main body 8, and is designed to come into sliding contact with the side surface of the tire when the metal fitting 8 is operated. Others, 19 is metal piece 1
This is the insertion window of the tongue piece 18 which has been opened.

According to the invented metal fittings having such a configuration,
One or two pieces of connected metal pieces 1 are attached to the drive wheels of an automobile. That is, as shown in FIG. 2, one end of a band 2 is fixed to one of both sides of the connected metal pieces 1, and can be attached to any location on the drive wheels of a stopped vehicle (a position that is easy to work on).
Pass the other end of the band 2 through the hole 4 of the tire wheel, and as shown in FIG. Pass the band through the holding piece 13 and fold it back at the piece 13. When threading the band through the band fixing rod 11, it is possible to easily thread the band 15 through the band 15 with the rod 11 pulled up counterclockwise in FIG. By tightening the band 2 after passing the band through, the belt fixing rod 11 is attached to the metal fitting body 8 as shown in the third figure.
Automatically fits and positions.

The band 2 may be tightened by placing the metal piece 1 along the tire surface and loosely wrapping the band 2 through the hole 4 of the tire wheel.

When tightening this band, the upper support shaft 10 in Fig.
The operating rod 12, which had fallen to the left side of the figure, is raised to the position shown by the solid line in the figure, and further pushed down to the right side of the support shaft 10 (the state shown by the chain line in the figure). By this operation, the shaft hole 16 portion of the rod 12 pivots around the support shaft 10, so that the metal piece 1 and the metal fitting body 8 are drawn together by the draw rod 17 passed therethrough. At this time, the metal fitting body 8 mainly moves, but its tongue piece 1
Since the main body 8 slides on the side surface of the tire, the main body 8 does not bite into the side surface of the tire, and this pulling operation can be easily and reliably performed.

As a result, the metal fitting of the present invention is tightly wrapped around the tire surface, and the operating rod 12 is not easily pulled up when the operating rod 12 is pressed against the metal fitting body 8 on the right side of the support shaft 10. Safe mounting of the metal fitting of the present invention is ensured, and it is even safer by passing the tip of the band 2 through the through hole 15 bored at the tip of the operating rod 12.

When removing the metal fitting of the present invention, by strongly pulling the tip of the band 2 under the attachment outward,
The operating rod 12 is pulled up, and it can then be easily removed by performing the reverse operation during the installation.

In this way, the metal fitting of the present invention uses a metal piece with claws that has excellent anti-slip ability on frozen roads, etc. instead of the conventional chain body as a tire anti-slip metal fitting, so that it can protect the circumferential surface of the tire of the driving wheel. It only needs to be attached to a portion of the circumferential surface in one or two places, and as a result, it can be easily attached while the vehicle is stopped, reducing the hassle of attaching and detaching when necessary. The metal fitting of the present invention is extremely practical as this type of anti-slip metal fitting, as it has a small amount of slippage and can be used effectively.
