Examples [Figures 1 to 9] Figure 8] a Sun visor b Vanity mirror b-1 Mirror attachment b-2 Lamp part b-3 Cover b-4 Adsorption part G Effects of the invention (A Field of industrial application) The present invention relates to a novel vanity mirror. Specifically, it is a vanity mirror equipped with a cover that opens and closes the front of the mirror, and by improving the structure of the attraction part that magnetically attracts the rotating end of the cover,
A part of the back cover provided on the rear side of the mirror body can be removed, thereby making it possible to make the vanity mirror thinner.

(B Overview of the invention) The vanity mirror of this invention has two suction parts that magnetically attract the rotating end of the cover that opens and closes the front of the mirror.
The mirror body, which supports the mirror, has an insertion hole for protruding a part of the yoke plate to the front. The yoke plate has a front end that is inserted into the insertion hole of the mirror body, and a rear end of the yoke plate. An engagement hole in which the engagement claw of the engagement piece is engaged is formed in the center of the closer portion, and protrusions projecting toward opposite sides are formed at positions on both sides of the engagement hole, and A permanent magnet is sandwiched between the two yoke plates, and the front end of the yoke plate touches the mirror body with the side edge of the rear end surface of the permanent magnet in contact with the protrusion protruding inward of the yoke plate. It is inserted into the insertion hole, and the engaging claw of the engaging piece of the mirror body is engaged with the engaging hole of the yoke plate and attached to the mirror body, whereby the yoke plate and the permanent magnet are attached to the rear part of the mirror body. There is no danger of the mirror falling off the mirror body even if it is not held down by the back cover, and the size of the back cover can be reduced accordingly, and the thickness of the vanity mirror can be made thinner.

(C Prior Art) [Figure 9] A vanity mirror installed in the driver's cabin of a car reflects light from the outside onto the mirror, and if the reflected light enters the driver's eyes, the driver will be dazzled. Therefore, a cover is often attached to cover the front of the mirror when it is not in use.

If a cover is provided, a means for locking the pivoting end of the cover is required to prevent the cover from swinging uncontrollably when not in use. The locking means generally utilizes magnetic attraction.

FIG. 9 shows an example of a vanity mirror equipped with a cover locking means utilizing such magnetic attraction.

b is a mirror body supporting mirror c;
A light bulb e is disposed in a recess d formed in the mirror body b adjacent to the support portion of the mirror c, and the front surface of the recess d is covered with a lens f to form a lamp portion g.

A back cover h is attached to the back side of the mirror body b, and the rear side of the mirror c is supported by the back cover h to prevent it from falling off from the mirror body b.

i is a cover whose upper edge is rotatably supported by mirror body b, and attracted plates j, j made of a magnetic material are attached to the rotating end side facing mirror body b. has been done.

K and k are suction parts provided on mirror body b at locations facing suction plates j and j when cover i is in the closed position, and each suction part k is attached to two yoke plates l and yoke. 1 and a permanent magnet m sandwiched between these yoke plates l.

Numerals n and n are recesses opened in the rear surface of the mirror body b, and two through holes o and o spaced apart from each other are formed in the front surface of each recess n.

The yoke plates l, l are arranged in the recess n, and their front ends reach the front surface of the mirror body b through the insertion holes o, o, and a permanent magnet is placed between the yoke plates l and l. m is located, and the rear opening of the recess n is closed by a part of the back cover h, whereby the yoke plates l,
l and a permanent magnet m are arranged within the recess n.

(Problem that the invention attempts to solve) [Figure 9] By the way, in the vanity mirror a mentioned above, the suction parts k, k do not close the openings of the recesses n, n with the back cover h. Then, the yoke plates l, l, . It is necessary for h to be long in the left and right directions, and to be arranged so as to straddle the lamp part g. Moreover, since the lamp part g requires a deep concave part d, the amount of rearward protrusion of the mirror body b in this part becomes large, and if the back cover h is located to the rear side of the part, There is a problem in that the thickness of the vanity mirror a becomes very large.

Therefore, we divided the back cover into two parts and
It may be possible to avoid placing a back cover on the back side of the device to prevent the thickness of that area from increasing, but in that case, two back covers would be required instead of one, and parts would be There is a problem that the number of parts and the number of assembly steps increase.

(E Means for Solving Problems) In order to solve the above-mentioned problems, the vanity mirror of the present invention has two yoke plates that magnetically attract the rotating end of the cover that opens and closes the front surface of the mirror. and a permanent magnet held between these yoke plates, and the mirror body supporting the mirror has an insertion hole for protruding a part of the yoke plate to the front and is located in contact with the insertion hole. An engagement piece is formed that protrudes toward the rear and has an engagement claw formed on the protruding end, and the front end of the yoke plate is inserted into the insertion hole of the mirror body, and the front end of the yoke plate has a front end that is inserted into the insertion hole of the mirror body. An engagement hole into which the engagement claw of the engagement piece is engaged is formed in the center, and protrusions projecting to opposite sides are formed on both sides of the engagement hole, and the two yoke plates are connected to each other. The permanent magnet is sandwiched between the two, and the front end of the yoke plate is inserted into the insertion hole of the mirror body with the side edge of the rear end face of the permanent magnet in contact with the protrusion protruding inward of the yoke plate. At the same time, the engaging pawl of the engaging piece of the mirror body is engaged with the engaging hole of the yoke plate to be attached to the mirror body.

Therefore, according to the vanity mirror of the present invention, the yoke plate and the permanent magnet that make up the adsorption part will not fall off from the mirror body even if the rear part is not held down by the back cover. Therefore, it is not necessary to position the back cover on the back side of the lamp portion, which protrudes a large amount to the rear, and it is possible to reduce the thickness of the vanity mirror.
In addition, since the two protrusions formed on the yoke plate protrude from the positions across the engagement hole to the opposite sides, even if the yoke plate is oriented in the opposite direction, either protrusion will not act as a permanent magnet. The yoke plate engages with the rear end edge, and the left and right directionality of the yoke plate does not pose a problem during assembly, resulting in good assembly workability. Moreover, this does not result in an increase in the number of parts or the number of assembly steps.
