Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-slip device to be mounted on an automobile tire.

[0002]

2. Description of the Related Art In this type of anti-slip device, as disclosed in Japanese Patent Application Laid-Open No. 9-315117, four anti-slip strips having the same mesh structure are wound around the outer periphery of a tire. And a back-side string portion detachably connected to the back side of the tire of the mesh-like band portion.

[0003] The reticulated band portion is configured such that a front-side connecting member fixed to one end of the front side of the tire is separably connected to a connection hole penetrating the other end of the front side of the tire. A plurality of hook pieces for hooking the attachment are fixed, and penetrate through a plurality of connection holes on the back side of the tire.

[0004] The back side string portion is configured such that a back side connecting member fixed to one end of a string shorter than the mesh band portion is separably connected to a loop formed at the other end of the string, and the same number of straps as the non-slip pieces are attached to the string. The connecting device is fixed, and a plurality of string connecting devices are movably attached to the string between the fixed type string connecting devices. Each fixed string connecting tool and each movable string connecting tool are separably connected to each connecting hole on the tire back side of the mesh band.

[0005] The anti-slip band is wound around the outer periphery of the tire and covered, and both ends of the anti-slip band are connected to the back side connecting tool and the front side connecting tool. Engage and pull the front side of the non-slip band toward the center of the tire with a rubber band elastic fastener.

[0006]

However, tires of automobiles are worn by use. Worn tires have smaller dimensions than new tires.

In the above-described non-slip device, if the non-slip band wound around the outer peripheral portion of the tire is set to a size suitable for a new tire, when the non-slip band is mounted on a worn tire, Adhesion, conformity or fit between the non-slip band and the worn tire is deteriorated.

Conversely, if the non-slip band is set to a size suitable for a worn tire, mounting the non-slip band on a new tire requires a lot of time and effort. The attachment of the non-slip band to a new tire becomes poor.

The inventor of the present invention has found the following as a cause of the deterioration of the fitting property and the wearing property of the non-slip band.

In the above-described non-slip device, the non-slip band is movable when the back-side cord portion is connected to the tire back side of the mesh band portion in which a plurality of non-slip pieces are connected in a band shape. Each of the string connectors of the formula is connected to each of the non-slip pieces of the mesh band, while each of the fixed string connectors of the back side of the strap is connected to each of the non-slip pieces of the mesh band.

[0011] Since the four non-slip pieces of the net-like band portion and the four locations of the back side string portion are respectively connected by fixed string connecting devices,
The relative movement of the mesh band and the back side string is greatly restricted by four fixed string connectors.

The cross section of the connecting hole of the anti-slip piece of the mesh band and the tip of the fixed or movable string connecting tool fitted in the connecting hole is rectangular. In the plane including the connection hole portion of the anti-slip piece of the mesh band portion, the connection hole portion and the distal end portion of the fixed or movable string connector are not configured to rotate relative to each other.

Therefore, in the non-slip band, the reticulated band portion and the back side string portion constituting the non-slip band are difficult to move relative to each other, and as a result, the fitting property and the mounting property are poor.

[0014]

Means for Solving the Problems 1) A non-slip band is wrapped around the outer periphery of an automobile tire, the both ends of the non-slip band are connected, and the back side of the non-slip band is engaged with the back surface of the tire.

A plurality of string connecting devices were attached, and each of the string connecting devices of the back side cord portion was connected to each connecting point on the tire back side of the mesh band.

2) A non-slip band is wrapped around the outer periphery of the tire of the automobile, and both ends of the non-slip band are connected to each other. In a non-slip device for a tire that pulls the front side toward the center of the tire, the non-slip band is composed of a mesh band portion and a shorter back-side string portion, and the back-side band portion has a plurality of string connectors attached to the string, Each of the string connecting devices of the back side string portion is connected to each connection point of the tire back side of the mesh band portion, and in a plane including each connection point portion of the tire back side of the mesh band portion, the connection point is respectively set. The part and the cord connector can be rotated relative to each other.

3) In the tire anti-slip device of the above 1), when connecting each of the string connecting devices of the back side cord portion and each connecting point of the tire back side of the mesh band portion, the tire back side edge of the mesh band portion is connected. In the plane including each connection point portion, the connection point portion and the string connection tool were relatively rotatable.

4) In the above-mentioned anti-slip device for each tire, each of the cord connectors of the back side cord portion is rotatable around the cord.

[0018]

In the anti-slip device for tires of 1) and 3) above, all of the string connecting devices of the back side of the string except the stationary type at both ends are movable type which move along the string, and are mesh-like. The relative movement of the band and the back side string is not greatly restricted by the string connecting tool.

In the tire slip prevention devices 2) and 3), the connection point portion and the cord connection member are relatively rotated in a plane including each connection point portion on the back side of the tire of the mesh band.

In the device for preventing slippage of the tire of the above 4), each of the cord connectors of the back side cord portion rotates around the cord.

In the tire anti-slip device of the present invention,
In the non-slip band, the net-like band portion and the back side string portion constituting the non-slip band are easy to move relative to each other, and have good fit and wearability.
