Description

[Detailed description of the invention] This invention relates to an anti-glare rearview mirror.

In conventional devices of this kind, a permanent magnet is fixed to a mirror member, and an electromagnet is fixed opposite the permanent magnet to a support member to which the mirror member is pivotally attached, and the polarity of the permanent magnet is changed by energizing the electromagnet. Some devices generate the same or opposite polarity to switch the angle of the mirror member between a normal position and an anti-glare position.

However, in such conventional devices, screws were used to fix the electromagnet to the support member, which had drawbacks such as being unable to fix the electromagnet without a screwing tool and requiring a lot of effort.

The object of this invention is to eliminate the drawbacks of the above-mentioned conventional mirrors and to provide an anti-glare rearview mirror which can be easily mounted without the need for tools to mount an electromagnet to a support member.

This invention will be explained with reference to embodiments shown in the drawings.

In FIGS. 1 and 2, 1 is a support member that is attached to the vehicle body via an appropriate attachment member (not shown), and 2 is a mirror member that is pivotally attached to the support member 1 via a support shaft 3, and is, for example, a prism-shaped mirror member. The mirror 4 and the mirror holder 5 are provided. 6,
Permanent magnets 6' are fixed behind the mirror member 2 by appropriate means via yokes 7 and 7' at the top and bottom of the support shaft 3, and permanent magnets 6 and 8,
The electromagnets are arranged on the front surface of the support member 1, facing the cores 9 and 6', respectively.
9' and yokes 10, 10'. Second
As shown in the figure, the electromagnets 8, 8' include a yoke 10,
Overhanging boards 11, 1 extending left and right from the base of 10'
1, 11', 11' are formed, while the support member 1 has recesses 12, 12, 12' for positioning the electromagnets 8, 8'.
12', and a hole 1 located above the recess 12 for stopping the upper end of the wire material 13, 13, such as a piano wire.
4, 14, and the wire material 1 located below the recess 12'.
The wire members 13, 13 are located between the holes 14', 14' that lock the lower ends of the wire members 13, 13, and the recesses 12, 12'.
Projecting pieces 15, 15 are formed to lock the intermediate portion of the. The depth of the recesses 12, 12' is shallower than the thickness of the overhanging plates 11, 11, 11', 11'. 14, 14', 14' and protrusions 15, 15.

The above anti-glare rear mirror has recesses 12 and 12'.
The overhanging plates 11, 11, 11', 11' are housed inside,
Both ends of the wire members 13, 13 are provided with holes 14, 14, 14',
14' and then the intermediate portion is pushed out to both sides as shown by the chain line in FIG. 13, 13 and recesses 12, 12' and are fixed. When the electromagnet 8' and the permanent magnet 6' are attracted, the mirror member 2 is in the normal position, and when the electromagnet 8 and the permanent magnet 6 are attracted, the mirror member 2 is switched to the anti-glare position.

In the above embodiment, the wire members 13, 13 were used to fix the electromagnets 8, 8', but the wire members 13, 13 may also be used to fix the permanent magnets 6, 6'. It goes without saying that this invention can be modified in various ways to the above-mentioned embodiments.

Since this invention is constructed as described above, the electromagnet can be easily attached to the support member without the need for tools, and the wire material used for attachment is extremely low cost. This has excellent effects such as reducing the cost of the anti-glare rearview mirror.
