ABSTRACT:
BACKGROUND OF THE INVENTION AND RELATED ART STATEMENT
The invention relates to a holding device for a shaft member, in particular, a shaft attached to a sun visor, so that the sun visor can be easily attached to or detached from a vehicle.
A conventional sun visor has been screwed to a car body through a bracket. However, in the conventional bracket, there have defects such that not only a special tool for screwing the sun visor to the car body but also much labor are required. Also, when the sun visor is disassembled, a special tool and much labor for removing screws are required.
In view of the above defects, the present invention has been made, and an object of the invention is to provide a holding device of a shaft member or a shaft for a sun visor, wherein the shaft or the shaft with the sun visor can be easily attached to or detached from the body.
Another object of the invention is to provide a holding device of a shaft member as stated above, wherein a holder can be easily detached from a base.
A further object of the invention is to provide a holding device of a shaft member as stated above, wherein the base can be easily detached from the body.
A still further object of the invention is to provide a holding device of a shaft member as stated above, wherein the holder can be easily attached to the base.
Further objects and advantages of the invention will be apparent from the following description of the invention.
SUMMARY OF THE INVENTION
In order to attain the above objects, according to a first aspect of the invention, a holding device includes a base and a holder. The base is fixed to an attaching hole of a car body, i.e. body. The holder rotatably supports a shaft of a sun visor, and is detachably fixed to the base.
The base has a base main portion and anchors. The base main portion includes an inserting hole having an outer diameter larger than that of the attaching hole. The anchors project from a back surface of the base main portion, and passes through the attaching hole of the body while the anchors are contracted or deformed. The anchors, after passing through the attaching hole, restore the shapes to engage a back surface of the body.
The holder includes a holder main portion and a supporting leg. The holder main portion includes a shaft hole for allowing a shaft to pass therethrough, and has a size larger than that of the inserting hole of the base main portion. The supporting leg projects from a back surface of the holder main portion, and passes through the inserting hole.
The supporting leg has lock portions. The lock portions engage the back surface of the base main portion when the lock portions are inserted into the inserting hole and the supporting leg is rotated from an inserted position.
According to a second aspect of the invention, the shaft includes a flange and a first groove. The flange is disposed at the middle of the shaft and extends from an outer periphery of the shaft. The flange has an outer diameter larger than that of the shaft hole of the holder main portion. The first groove extends to a center of the shaft from the outer periphery of the flange.
The holder main portion is provided with second grooves for releasing lock. The second grooves extend radially outwardly from an inner circumferential surface of the shaft hole. One of the second groove communicates with the first groove at a position where the supporting leg is locked in the inserting hole of the base main portion.
According to a third aspect of the invention, the base main portion is provided with lock releasing holes. The lock releasing holes pass through the front and back surfaces of the base main portion to face the anchors.
According to a fourth aspect of the invention, key grooves are provided to an outer periphery of the shaft extended from the flange. On the other hand, keys are provided to the holder main portion. The keys can be fitted into the key grooves, but normally they are separated from the key grooves to be opposed to each other. The base main portion includes pressing portions. The pressing portions push the keys into the key grooves at the pressing positions, and are disengaged from the keys at the lock positions.
