Description

[Detailed Description of the Invention] This invention relates to an anti-glare mirror for automobiles whose deflection angle can be adjusted.

Anti-glare mirrors are used as inside mirrors in automobiles, and utilize the front and back reflections of a prism mirror.

In other words, during the day, use the highly reflective back surface to check the situation behind you, and at night, change the deflection angle of the mirror surface to use a low reflective surface to avoid receiving strong light reflected from the headlights of the following vehicle. It is.

(For example, see Japanese Utility Model Publication No. 53-42903.) By changing this deflection angle, the reflection angle of the mirror surface can be changed, but since there is generally a manufacturing error when finishing the mirror surface, fine adjustments must be made to make the deflection angle appropriate. The angle must be adjusted accordingly.

The present invention allows this angle adjustment to be easily and finely performed on a mirror attached to a vehicle body, and its structure will now be explained with reference to an embodiment shown in the drawings.

A mirror surface 2 is fitted into the opening of the mirror case 1,
Support shafts 3a, 3a of the pivot 3 are rotatably supported on brackets la, 1a provided in the case 1.

The pivot 3 is attached to a stay 4 fixed to a vehicle body (not shown) via a ball joint 5.

Therefore, the case 1 can be positioned in a desired direction with the ball joint 5 as the center.

Also, another bracket 1b provided inside the case 1.

Support shafts 6a, 6a of the switching lever 6 are rotatably supported on the switching lever 1b, and a knob 6b of the switching lever 6 projects outside the case 1.

The end edge 6c of the switching lever 6 is fitted into a slot 3b provided at the end of the pivot 3.

Therefore, when the lever 6b of the switching lever 6 is rotated in the E-E direction about the support shaft 6a as shown in FIG.
The edge 6c of the lever 6 and the pivot 3 come into contact with each other.
Through the engagement with the split groove 3b, the case 1 swings about the support shaft 3a.

Therefore, the mirror surface 2 also oscillates, and the reflection angle is changed by changing the oscillation angle.

Now, in the present invention, the end edge 6c of the switching lever 6 is
As shown in the figure, it is formed to form an inclined portion 6f.

Therefore, when the knob 6b of the lever 6 is moved laterally in the direction F as shown in FIG. .

As a result, as shown in FIG. 4, since the relative deflection angle of the pivot 3 becomes θgK, the deflection angle of the mirror surface 2 also becomes θg.

When the knob 6b of the lever 6 is moved laterally in the H direction as shown in FIG.
Ru.

As a result, as shown in FIG. 4, since the relative deflection angle of the pivot 3 becomes θkK, the deflection angle of the mirror surface 2 also becomes θk.

FIGS. 5 and 6 show an embodiment of a mechanism in which the switching lever 6 is moved laterally with a sense of moderation and is maintained at the moved position.

That is, one support shaft 6a of the switching lever 6 has a circular cross section, and the other support shaft 6m has an elliptical cross section, and several circumferential grooves 6n are provided in accordance with the number of steps of lateral movement.

The support shaft 6m is received by a partially opened support portion 1d provided in the bracket lb of the case 1.

This support portion 1d is designed to constantly press and crush the support shaft 6m having an elliptical cross section.

Therefore, by lateral movement of the switching lever 6, the circumferential groove 6n of the support shaft 6m is fitted into the support portion 1d, and a sense of moderation in movement is obtained. You can feel it.

In addition, the support shaft 6m has a circular cross section and a circumferential groove is provided on it.
Even if the support shaft 6a has an elliptical cross-section and is pressed and crushed by a partially open support portion, the same sense of moderation as described above can be obtained.

As mentioned above, the operating angle of the housing 6b of the switching lever 6 is
The relative deflection angle of the pivot 3 is constant due to the rotation in the -E direction, but the relative deflection angle of the pivot 3 is in the range from θg to θ due to the lateral movement of the lever 6, and an appropriate angle can be selected from this range, so the mirror surface 2Q The deflection angle can also be adjusted within this angle.

That is, in the present invention, by moving the switching lever laterally with the □ mirror attached to the vehicle body, the deflection angle of the mirror surface can be arbitrarily and finely adjusted, and its practical effects are great.
