Description

[Detailed Description of the Invention] The present invention relates to a novel full-length mirror that allows you to see your back.

Traditionally, mirrors have been widely used as essential tools in daily life, and many of them are used as full-length mirrors.

Mirrors used for full-length mirrors include flat mirrors, three-sided mirrors, and three-sided mirrors, but these are used to observe the person's front, side, or diagonal side, and are used to accurately see the person's back, or rear view. I can't.

Japanese Utility Model Application No. 48-30099 discloses a mirror that allows one to see the front, side, and top surfaces of a person's head, but even in this mirror, the back surface of the head cannot be seen at all.

However, if one's own back can be easily observed, it is often very convenient, for example, when putting on or designing Japanese clothes.

Furthermore, since the rear view is considered an important element of fashion, there was a strong demand for a device that would allow people to see their own rear view.

The present invention was devised in view of the above-mentioned circumstances, and is intended to meet the above-mentioned requirements by applying four mirrors (plane mirrors).

Hereinafter, the present invention will be explained in detail based on the drawings.

In Figure 1, 1 is the imaginary center line 45 behind the observer M who is trying to see his or her own back in the front-rear direction.
A first mirror provided at an angle of 1°, a second mirror 2 on the left side of this mirror 1, a fourth mirror 4 on the right side, and a second mirror 4 on the right side of this mirror 1.
The mirrors 1 and 2 are provided at an angle of 900 degrees with respect to the mirror 1, respectively, and are opposed to each other with a constant interval a.

3 is a third mirror parallel to the first mirror 1 and spaced apart from it.
It is a mirror of

The distance a between the mirrors is such that the observer M can enter the space surrounded by the mirrors 1 to 4.

Also, mirror 1 is attached to frame 11, mirror 2 is attached to frame 21, and mirror 3 is attached to frame 31.
The mirrors 4 are respectively attached to the frames 41, and the frames 11 are placed in positions where adjacent mirrors form an angle of 900 degrees with each other as described above.
．． 21. Connect 31 and 41 securely.

Next, the operation of the present invention will be explained.

When an observer M stands at a predetermined position indicated by a solid line in a space surrounded by mirrors 1.2.3.4 shown in FIG. 2, a virtual image M1 is generated by the first mirror 1 (one-time reflected image), Below, the virtual image M
1 is projected by the second mirror 2 to form a virtual image M2 (twice reflected image), that virtual image M2 is projected by the third mirror 3 to form a virtual image M3 (three times reflected image), and the virtual image M3 is projected by the fourth mirror 4 to produce a virtual image M4 (four-times reflected image) shown by a chain line.

In addition, l, 12.13, 14.15, and 1 shown in Figure 2
6. The distances 17 and 18 are equal due to the general physical properties of mirrors.

The virtual pigeon is an image that appears in front of the observer M, and faces in the same direction as the person.

Therefore, the observer M can clearly see his own back (rear view) in the fourth mirror 4.

In this way, the full-length mirror of the present invention allows you to see yourself in front of you for the first time by optically combining four mirrors, which was impossible with conventional full-length mirrors. The back side of the camera can be observed easily and accurately.

Therefore, the present invention has excellent practicality and can be expected to be widely applied not only when dressing and designing Japanese clothes but also when trying on clothes at clothing stores.
