[Detailed Description of the Invention] Technical Field The present invention relates to a mirror device configured as a hand mirror, a mirror with a stand, a full-length mirror, or the like.

PRIOR ART When trying to see, for example, a small part of the inside of the mouth using the above-mentioned mirror device, it is very difficult to see because the inside of the mouth is dark. Therefore, the mirror body of the mirror device,
A light source is placed in a space partitioned by a mirror case that holds the light source, and a light transmission window is formed in the mirror portion facing the light source, and the light from the light source is emitted to the outside through the light transmission window. A mirror device has already been proposed in which a portion to be viewed is illuminated using this light, and this portion is brightly reflected onto a mirror body. To actually construct such a mirror device, it is necessary to pull out the electric cord from the light source outside the mirror case, connect it to a power source, and turn on the light source. However, when configured like this,
The electrical cord pulled out from the mirror case is fully visible from the outside, significantly degrading its appearance.

On the other hand, there is also a known mirror device in which a mirror case holding a mirror body is pivotally supported on a support arm, and the mirror case and mirror body are rotated with respect to the support arm as necessary. The support arm of the mirror device was used exclusively for the purpose of supporting the mirror case.

Purpose The purpose of the present invention is to provide a mirror device in which the electrical cord drawn out from the mirror case is not visible from the outside and the appearance thereof is improved.

Configuration In order to achieve the above object, the present invention holds a mirror body in a mirror case, and arranges a light source supported by the mirror case in a space partitioned by the back side of the mirror body and the mirror case. A mirror device in which a light transmitting window is formed in a portion of a mirror body facing a light source, and the mirror case is rotatably supported on a support arm, the support arm comprising a hollow arm body and a hollow arm body; It has a mounting member integrally fixed to the upper part and an ear integrally protruding from the mounting member,
The ear is formed with a through hole and a through hole that communicates the through hole with the inside of the arm body, and the through hole is formed in the side wall of the mirror case that partitions the recess formed in the back surface of the mirror case. A screw member is inserted into the hole and the through hole formed in the ear, and is not rotatable with respect to the ear, but rotatable relative to the mirror case, and is pressed against the surface of the side wall of the mirror case. A brake washer is fitted onto the threaded member, a nut is screwed onto the threaded portion of the threaded member to hold the threaded member and the brake washer against the support arm, and an electrical cord from the light source is connected. proposes a mirror device, characterized in that the mirror device is inserted into an arm body through a through hole formed in the axial direction of the screw member and the through hole formed in the ear.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an example of a mirror device 1 according to the present invention, and FIG. 2 is a cross-sectional view taken along the line -- in FIG. It is configured as a concave mirror with Therefore, in the following description, reference numeral 2 will be used for the concave mirror. It goes without saying that a mirror body other than a concave mirror, such as a plane mirror, may be used.

The concave mirror 2 is fixedly held via a holder 13 to a mirror case 3 located on the back side thereof, and the mirror case 3 is supported by a support arm 5 of a stand 4 fixed to the mirror case 3. The base 6 of the stand 4 is placed at an appropriate location, such as on a desk. When the mirror device is configured as a hand mirror, the base 6 is omitted.

The holder 13 is formed into a ring shape as shown in FIG.
A is formed to protrude in the radial direction. To fix the concave mirror 2 to the mirror case 3 using the holder 13, the mirror case 3 and the concave mirror 2 are combined as shown in FIG. The locking tongue piece 13a is brought close to the mirror case 3 and elastically deformed as shown by the chain line, and the locking tongue piece 13a is moved over the edge of the mirror case 3, and the holder 13 is attached as shown in FIG.
The concave mirror 2 and the mirror case 3 are integrally fixed and locked. The holder 13 is made of synthetic resin, for example.

Since the mirror case 3 is located on the back side of the concave mirror 2, the back side of the concave mirror 2 and the mirror case 3
A space S (FIG. 2) is defined by. In this space S, a light source 7 made of, for example, a miniature light bulb is arranged. The light source 7 is supported by a socket 7a fixed to the mirror case 3 in a state facing the back side of the concave mirror 2, and is connected to a switch 20 attached to the base 6 and from the switch 20 to a power source via an electric cord, which will be described later. connected to. Since the light source 7 supported by the mirror case 3 is housed inside the space S, even if the light source 7 is provided, it can be covered up and the appearance of the mirror device 1 will not be impaired. .

A light transmitting window 8 is formed in the concave mirror portion facing the light source 7, and in the illustrated example, a reflective material is not provided on the glass portion of the light transmitting window 8, and the structure is such that light can pass through this glass portion. , this is used as a light transmission window 8. A through hole may be formed in the concave mirror portion facing the light source 7, and this may be used as the light transmission window 8.

The mirror device 1 described above can be used in the same way as a normal mirror, for example by projecting one's own face onto the concave mirror 2, but it can also be used for other purposes, such as clearly viewing a small part of a dark mouth. In this case, the power switch 20 is pressed to turn on the light source 7, and the light passes through the light transmission window 8 and hits a small part of the mouth. Since the area to be viewed can be illuminated with light in this manner, the small area to be viewed is bright and is magnified by the function of the concave mirror 2 and projected onto the concave mirror 2. Therefore, this can be clearly seen,
It is possible to eliminate the difficulty in viewing.

If the light from the light source 7 is directly emitted from the transparent light-transmitting window 8, it may cause glare to the human eye.In such a case, the glass portion of the light-transmitting window 8 may be made of frosted glass. , or a cover 1 made of frosted glass, etc., as shown by the chain line in FIG.
It is preferable to cover the light source 7 with the light source 7 and soften the light emitted from the light transmission window 8. Alternatively, the mirror case 3 and the holder 13 may be formed integrally, and the concave mirror 2 may be held therein.

On the other hand, the mirror case 3 holding the concave mirror 2 is
As shown in FIGS. 5 and 6, screw members 27, 2
The mirror case 3 is rotatably supported on the support arm 5 via a swinging device 40 having a swivel 7a, so that the mirror case 3 can be rotated relative to the support arm 5 as shown by the chain and broken lines in FIG. It is configured.

The specific configuration of the swinging device 40 will be explained while explaining an example of a procedure for connecting the mirror case 3 and the support arm 5.

FIG. 5 shows the mirror case 3 to which the concave mirror 2 and therefore the holder 13 are not attached, as seen from the back side, which is not the side where the light source 7 (FIG. 2) is attached. ing. The mirror case 3 has a recessed part 21 in the center of its back surface.
are formed, and through holes 22,
22a are formed respectively. The mirror case 3 is made of synthetic resin such as ABS resin, for example.

On the other hand, the support arm 5 has a hollow arm body 23.
, a mounting member 24 integrally fixed to the upper part of the main body 23, and a pair of ears 25, 25a integrally protruding from the mounting member 24, and through holes 26, 25a are formed in these ears. 26a, and a through hole 4 that allows the through holes 26, 26a to communicate with the inside of the arm body 23.
2 and 42a are formed through each other.

In order to connect the mirror case 3 formed as described above and the support arm 5, as shown in FIGS. through hole 2
6, 26a, and each screw member 27,
The heads 54, 54a of 27a are placed on the end surfaces of the respective ears 25, 25a, and the first brake washers 33,
Screw member 2 with 33a protruding from ears 25, 25a
7, 27a to fit into the shaft portion.

Next, insert each screw member 2 into each through hole 22, 22a of mirror case 3 from the back side of mirror case 3.
Insert the shaft parts of 7 and 27a, and tighten each screw member 27 and 2.
The shaft portion of 7a is made to protrude toward the side of the mirror case surface on which the light source 7 is attached. After doing this, the second brake washers 29, 29a, stoppers 30, 30a, and spring washers 31, 31a are fitted in this order to the shaft portions of the respective screw members that protrude. Finally, nuts 32, 32a are screwed into the threaded portions formed in the shaft portions of the protruding screw members 27, 27a,
Tighten this appropriately, hold the screw members 27, 27a and the brake washers 29, 29a, 33, 33a against the support arm 5, and
7a is prevented from coming off from the mirror case 3 and the support arm 5. In addition, by appropriately tightening the nuts 32, 32a, each mirror case side wall portion 28, 28a and the first and second brake washers 33, 33a, 29, 29a located on both sides thereof can be
Press them together with appropriate pressure. In this way, the support arm 5 and the mirror case 3 are connected to each other as shown in FIG. 6, and the concave mirror 2 is held in the mirror case 3 via the holder 13 as described above.

As is clear from FIG. 5, the screw members 27, 27a described above have an oval-shaped shaft portion with a threaded portion formed therein, and the through holes 26, 26a of the support arm 5 into which this shaft portion fits, and the stoppers 30, 30a. The hole is also formed in an oval shape corresponding to the shaft portion of the screw member. Therefore, each screw member 27, 27a and the stopper 30, 30a do not rotate relative to the support arm 5, but since the through holes 22, 22a formed in the mirror case 3 are circular, the mirror case 3 can rotate together with the concave mirror 2 around the screw members 27, 27a relative to the support arm 5.

In this way, the screw members 27, 27a are inserted into the through holes 22, 22a formed in the mirror case side walls 28, 28a and the through holes 26, 26a formed in the ears 25, 25a. 25a is unrotatable, and is inserted into the mirror case 3 so as to be relatively rotatable.

can be stopped and held at a desired angular position. Further, the frictional force between the stoppers 30, 30a and the spring washers 31, 31a and the second brake washers 29, 29a, which are placed in contact with each other on both sides thereof, also acts as a braking force. Nut 32,
By adjusting the tightening force of 32a, the braking force acting on the mirror case can be adjusted.

Further, as described above, since the rotation of the screw members 27, 27a and the stoppers 30, 30a is prevented, the nuts 32, 32 screwed onto the screw members 27, 27a are prevented from rotating.
a also does not rotate, so these nuts 32, 32
a can be prevented from loosening over time, and it is possible to maintain a constant braking force at all times. Even if the nuts 32, 32a become somewhat loose,
Due to the spring action of the spring washers 31 and 31a, the tightening force exerted by the nut can always be kept constant.

As mentioned above, the mirror case 3 is attached to the support arm 5
