Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base for a tire anti-skid device for an automobile and a tire anti-skid device using the same.

[0002]

2. Description of the Related Art Conventionally, an anti-slip body having an anti-slip arm portion can be easily attached to and detached from a base body provided on a wheel by a engaging means without jacking up when necessary, and the structure is simple and vibration generated in a vehicle body during traveling. The present applicant has previously proposed a tire anti-slip device that can suppress the stress acting on the anti-slip arm while suppressing
The basic invention was proposed in Japanese Patent No. 5307.

However, when the vehicle starts on a steep slope such as a frozen mountain road, an unexpected and unreasonable force acts on the anti-slip arm portion to disengage the engaging portion and the engaged portion from the engaging means. There was a fear. Further, when the non-slip body is unnecessary, the base body protrudes from one end of the wheel in the axial direction and remains, so that the base body may come into contact with the curb of the road and be damaged during parking. Therefore, there was a problem in putting it to practical use.

[0004]

SUMMARY OF THE INVENTION According to the present invention, like the conventional tire anti-skid device, it is possible to easily attach / detach without the need for jacking up, and to suppress the vibration generated in the vehicle body during traveling. It is an object of the present invention to provide a tire anti-slip device that is capable of strongly holding the anti-slip body on the base body when it is mounted and is excellent in safety, while providing a base body that is not easily damaged when not in use.

[0005]

In the first means, a wheel body on which a tire is mounted is provided at one axial end of the wheel body at a substantially outer peripheral edge portion thereof concentrically with the wheel body.
A base body having a pair of opposing fitting surfaces extending substantially parallel to the outer wall surface of the tire that guides in a substantially radial direction; and a passive fitting body from the outer periphery of the passive fitting portion. Anti-slip composed of an active fitting body portion which can be fitted and removed in a radial direction into a portion, and a plate-like spring-like anti-slip arm portion having a bending portion and one end of which is connected to the active fitting body portion A body; and the active mating body fitted to the passive mating body part in connection with a transition operation for forcibly moving the active mating body part radially inward from on the outer periphery of the passive mating body part. A first engaged portion provided in the passive fitting body portion or a first engaged portion provided in the active fitting body portion, for preventing the portion from being disengaged from the passive fitting body portion; A first engaging means composed of a first engaging portion that engages with the first engaged portion; When migrating radially inwardly of 該能 Dohama coalescence portion from the outer periphery of the receiving Dohama coalescence unit, 該能 Dohama coalescence unit by said first engagement means is held in receiving Dohama coalescence unit,
In a tire anti-skid device for an automobile in which the other end of the anti-slip arm is joined to a tread of a tire, in a direction in which the engagement between the first engaging portion and the first engaged portion is strengthened. A tire slip stopper for an automobile, comprising: a biasing means for biasing and / or a holding means for holding the engaged state of the first engaging portion and the first engaged portion. The device is configured.

[0006]

In the first solution means, when the active fitting body portion is moved inward in the radial direction from the outer periphery of the passive fitting body portion, the active fitting body portion is made to move by the first engaging means. The non-slip body will be attached to the base body by being held by the urging means and / or the urging means for urging the first engagement portion and the first engaged portion in a direction in which the engagement is strengthened. Since the holding means for holding the engaged state of the first engaging portion and the first engaged portion is provided, both of these urging means and holding means are the first locking portion. Since the first engaged portion and the first engaged portion do not easily come off, the active fitting body portion does not come off easily from the passive fitting body portion, and the non-slip body can be strongly held on the base body.
