Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement of an inside mirror device.

(Prior art) The inside mirror device is installed in the upper part of the room in front of the driver's seat.
Conventionally, inside mirror devices as shown in FIGS. 13 to 15 have been proposed.

This inside mirror device has a pivot receiving part 6 having a one-spherical fitting hole formed on the outside of the rear part 2 of the mirror body 1 and protruding integrally with the mirror body 1. A pair of clamping plates 9.10 are formed with holes 7.8.

Tighten plate part 9.10 by screw 11 and nut 12
The fitting force between the pivot receiving portion 6 and the spherical pivot 5 can be adjusted by tightening the spherical pivot 5.

By the way, with an inside mirror, if the mirror body 3 is placed too far away from the driver, visibility will be impaired, and if the mirror body 3 is placed too close to the driver, the visual IQI will be reduced. If the II distance is too small, the driver will feel pressured, so it is necessary to ensure an appropriate line-of-sight distance.

However, in the inside mirror device in which this fitting force can be adjusted, the pivot receiving part 6 is formed to protrude toward the outside of the back part 2, so in order to increase the line of sight distance, the ball is removed from the mirror body 3. Center 0 of shape pivot 5
The distance to If you try to make it smaller, the distance from the back part 2 to the mirror body 3 will inevitably become smaller, the mirror body 1 itself will become thinner, the rigid body strength of the mirror body l will decrease, and the support rigidity will be insufficient. There is a problem.

The inside mirror device shown in FIG.
A pivot receiving part 4 is provided between the body side stay 5 and the spherical pivot 6 formed at the tip of the vehicle body side stay 5.
The structure is such that the stay 5 supports the mirror body 1 so as to be tiltable about the spherical pivot 6. Further, the inside mirror device shown in FIGS. 11 and 12 has a structure in which the pivot receiving part 4 is fitted and fixed to the back part 2, and the mirror body 1 is supported by the stay 5 so as to be tiltable. Therefore, these structures are based on the distance from the mirror to the center of the spherical pivot. is getting smaller.

(Problems to be Solved by the Invention) However, in both of these inside mirror devices, the pivot receiving part 4 and the mirror body 1 are formed separately, and it is troublesome to attach the pivot receiving part 4 to the mirror body 1. It has certain defects. Furthermore, if play occurs due to friction or the like between the pivot receiving part 4 and the spherical pivot 6, the entire pivot receiving part 6 must be replaced, which causes troublesome replacement work. .

(Objective of the Invention) Therefore, one object of the present invention is to provide an inside mirror device that can be expected to improve the support rigidity of the mirror body while ensuring an appropriate line-of-sight distance G'Rt from the mirror body to the driver's eyes. It is in.

Here, the pair of tightening plate portions 24,25 are.

They are configured to face each other with an interval in the vertical direction. As shown in FIG. 1, threaded holes 26, 27 are formed in the pair of tightening plate parts 24, 25, respectively.

A screw 28 shown in FIG. 3 is inserted into the screw hole 26, 27. In this embodiment, the screw holes 26 and 27 have a long hole shape extending toward the back surface 14 in order to facilitate mold cutting during molding of the mirror body 13, but they have a circular shape. It is also possible to do this.

As shown in FIGS. 3 to 5, an opening 29 is formed in the upper surface portion 16 of the mirror body 13 so as to face the tightening plate portion 24. As shown in FIGS. Through this opening 29, the tip of a screw tightening tool (not shown) is inserted into the inside of the mirror body 13 together with the screw 28. The screw holes 26 and 27 are connected to the spherical fitting hole 2 as shown in FIGS. 2 and 6, respectively.

By tightening 8, the fitting force can be increased.

In addition, in FIGS. 1, 4, and 5, 34 is the screw 2.
This is a stepped portion formed on the tightening plate portion 24 to match the shape of the head of the figure 8.

In the inside mirror device according to the present invention, as shown in FIG. 2, the center of the spherical fitting hole 21 is 0. Since the distance MLt from the rear surface portion 14 of the mirror body 13 to the mirror body 3 can be increased relative to the distance 1IIL from the mirror body 3 to the mirror body 3, the mirror body can be made thicker without bringing the mirror body closer to the driver. .

(Effects of the Invention) As explained above, the present invention forms a pivot receiving part that fits and holds a spherical pivot so as to protrude toward the inside of a mirror body, and a clamping plate part that is integrated with the mirror body. Since the mirror body is formed inside the body, the mirror body can be made thick without impairing the feeling of pressure on the driver, and the supporting rigidity of the mirror body can be improved.

In addition, since the pivot receiving part and the pair of clamping plates are formed protruding from the inside of the mirror body, the appearance is lower than that of an inside mirror device in which the pivot receiving part and the pair of clamping plates are formed protrudingly from the outside of the back surface. It also has the effect of improving the appearance of the top.

Furthermore, since the opening for tightening the screw is formed in the mirror body so as to face the tightening plate, even if there is play between the spherical fitting hole and the spherical pivot, it can be easily removed through the opening. The tightening work can be performed on the

In addition, since the screws, tightening plate, and pivot receiver do not protrude outside the mirror body, the outer surface can be rounded and safety is improved.
