DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sun visor holder for an automobile, which removably holds the other end of a sun visor body having one end rotatably supported.

[0002]

2. Description of the Related Art In a sun visor for an automobile, one end of a sun visor body is supported so as to be rotatable from an initial position along an upper edge of a front window to a side window in accordance with the direction of solar radiation. A holder that detachably holds the other end of the sun visor body so that the sun visor body is stably supported is used.

In this type of holder, a connecting shaft provided at the other end of the sun visor body is received inside the hook and is locked by a locking piece which can be retracted and retracted. There is known a structure in which a locking piece is formed integrally with a main body member made of steel and a locking piece is caused to protrude and retract by its own elastic deformation (Japanese Patent Publication No. 61-1986).
No. 19449). There is also known a configuration in which a metal spring member is provided on the back side of a locking member that locks a connecting shaft portion received inside a hook portion, and the locking member is urged in a protruding direction (Japanese Patent Laid-Open No. H10-208572). 7-285335).

[0004]

The structure in which the locking piece is formed integrally with the main body member made of synthetic resin has the advantages of reducing the number of parts, improving the appearance, and not damaging the connecting shaft portion. On the other hand, it is inevitable that the holding force is weakened due to a change in the spring characteristic of the synthetic resin material due to a change in the vehicle interior temperature. In addition, if the locking piece is left for a long time in a state of being largely bent due to incomplete holding of the connecting shaft, the holding force may be significantly reduced due to permanent distortion.

[0005] On the other hand, in the configuration in which the metal spring member is provided, the spring characteristics are not affected by temperature changes and permanent distortion due to a continuous load hardly occurs, so that a stable holding force can be obtained. The structure tends to be complicated, for example, the holding member is screwed in order to securely lock to the main body member, so that the assembling workability is deteriorated and the number of parts increases.

[0006] The present invention has been devised to solve such problems of the prior art, and its main objects are as follows.
While suppressing the decrease in assembly workability and the increase in the number of parts,
It is an object of the present invention to provide an automobile sun visor holder configured to ensure a stable holding force.

[0007]

According to the present invention, a connecting shaft (5) provided at the other end of a sun visor body (4) rotatably supported at one end. ) Is detachably held by receiving the connecting shaft portion inside the hook portion (7) so as to be detachably held.
In the holder, the locking portion is formed integrally with a synthetic resin main body member (9) having a hook portion, and the holding portion is urged in the projecting direction on the back side of the locking portion. A metal spring member (10) was provided.

According to this, since the connecting shaft is locked and held by the elastic force of the spring member substantially made of a metal material, a stable holding force can be secured. In addition, since the locking portion is formed integrally with the main body member, it is possible to suppress a reduction in assembling workability and an increase in the number of components. In addition, the locking portion itself also generates a resilient force due to elastic deformation, but in order to prevent the fluctuation of the resilient force due to temperature change or the like from having a large effect on the holding force, the resilient force of the locking portion should be reduced. It is good to set.

In particular, the spring member (10) is a coil spring, and is provided with a pressing member (16) that fits inside the peripheral wall of the spring accommodating portion (15) provided on the back side of the locking portion. Is formed with an elastic locking piece (17) that engages with the peripheral wall of the spring accommodating portion, and the opposing surfaces of the pressing member and the locking portion each have a projection (18, 19) inserted into the center of the spring member. Is preferably provided.

[0010] According to this, it is possible to assemble simply by pushing the pressing member into the peripheral wall of the spring accommodating portion, and the assembling workability is improved. Moreover, since the pressing member is securely fixed to the peripheral wall of the spring accommodating portion, and the displacement of the spring member is regulated by the projection, a stable operation can be ensured without rattling of the spring member.

The spring member (31) is obtained by bending a metal plate, and is fitted to the inside of the peripheral wall of the spring accommodating portion (15) provided on the back side of the locking portion (8). ), And a leaf spring portion (33) extending from the base portion and abutting against the back surface of the locking portion. An elastic locking piece (34) is formed on the base portion to engage with the peripheral wall of the spring housing portion. It is good to have a configuration.

[0012] According to this, the spring member can be assembled simply by pushing the spring member into the peripheral wall of the spring accommodating portion, and the assembling workability is improved. In addition, since the base is securely fixed to the peripheral wall of the spring accommodating portion, a stable operation can be ensured without rattling of the spring member.

, The elastic wall 17 is provided on each of the opposing portions of the peripheral wall 21, and the projections 18 are erected on the bottom wall 22 so as to partially protrude from the opening of the peripheral wall 21. The pressing member 16 can be obtained by integral molding of a synthetic resin material having flexibility.

The elastic locking piece 17 protrudes from the outer surface of the peripheral wall 21 and engages with the edge of the locking hole 23 formed in the peripheral wall of the spring accommodating portion 15 so that the pressing member 16 is securely connected to the main body member 9. Fixed to The elastic locking piece 17 is formed in such a manner that the peripheral wall 21 is cut out and extends from the edge thereof to the bottom wall 22 side, and the outer surface is formed in an inclined shape in which the bottom wall 22 side is high, thereby holding down. The member 16 is the spring housing 1
5 can be smoothly fitted into the peripheral wall and the escape can be reliably prevented.

FIG. 5 shows a second embodiment of a holder for a sun visor for an automobile according to the present invention. This holder 3
0, the spring member 3 is attached to the main body member 9 shown in the above embodiment.
The spring member 31 is obtained by bending a metal plate and is fitted into the inside of the peripheral wall of the spring accommodating portion 15 provided on the back side of the locking portion 8.
A leaf spring portion 33 extending from 2 and abutting on the back surface of the locking portion 8
An elastic locking piece 34 is formed on the base 32 to engage with the peripheral wall of the spring housing 15.
