Description

[Detailed Description of the Invention] <Industrial field of application> The present invention is an improvement of a confirmation window for visitors, etc., using a half mirror (hereinafter referred to as a half mirror) that can be seen through from one side and cannot be seen through from the other side. It is about.

<Prior art> Generally, in order to confirm a visitor or the like indoors, the visitor is very natural without causing the visitor to feel unnatural or nervous, and without making the visitor sense the existence of the confirmer. It is desired to be able to accurately confirm the appearance or the whole picture in such a state.

For example, in Japanese Utility Model Laid-Open No. 57-172894, a reflector is provided in front of a peephole of a normal door using a fisheye lens, that is, a visitor side, and a visitor in front of a door or a chime button is identified as an indoor confirmer. A security device has been proposed in which the information is confirmed through a peephole and a reflecting mirror.

Further, Japanese Utility Model Application Laid-Open No. 58-104295 proposes an example in which the half mirror is used by being fitted in the regular door.

<Problems to be Solved by the Invention> In the above-mentioned conventional technology, the proposal of Japanese Utility Model Laid-Open No. 57-172894 not only prevents the reflector mounted in front of the door from interfering with the work such as cleaning the front surface of the door. In order to prevent the door from falling off due to impact when opening and closing the door, a strong holding structure for the reflector is required, resulting in a loss of aesthetics and a sense of discomfort to visitors.
Even if you get tired of it, such as making you feel uncomfortable, you only have to pursue the needs of the confirming person, lacking consideration for visitors, and there are many problems in practical use.

Further, when confirming a visitor from a conventional peephole using a fisheye lens, it is difficult to confirm unless the user approaches the door and presses his / her eyes on the peephole. Even so, the actual image of the visitor is reduced. Since it is bent and curved, the above-mentioned difficulty of confirmation is further promoted, and as a result, in general, even if a peephole is provided, it is not used.

In addition, the proposal of Japanese Utility Model Laid-Open No. 58-104295 does not have the above-mentioned problems, but the mirror fitted in the door gives a feeling of strangeness to the visitor.

Moreover, unless the illuminance on the visitor side is always higher than the illuminance on the confirmer side, the confirming action by the confirmer cannot achieve its purpose.

Also, when the difference in illuminance between the confirmer side and the visitor side is small, when the confirmer looks through the half mirror and peeks into the visitor, the confirmer himself / herself is projected on the half mirror to confirm the image of the visitor. People's images overlap and prevent confirmation. Moreover, when the condition of illuminance is reversed, not only is it useless at all, but it is also extremely inconvenient for crime prevention, such as the visitor can observe the side of the confirmer and further indoors. It occurs, but there is no way to prevent it.

The present invention provides a confirmation window that solves the problems of the conventional proposals.

<Means for Solving the Problems> In order to solve the above-mentioned problems, the present invention provides a half-mirror in which one of the through-transparent windows is seen from one side to the other, or from the other side to the other, in order to solve the above-mentioned problems. Is inclined and attached, and a real image is provided on the surface of the interior material facing the half mirror from the attachment position of the half mirror to the confirmed person side of the through transparent window.

<Operation> In the present invention, the half mirror 3 is tilted from one side to the other side as shown in FIG. 1 (b), or from the other side to one side as shown in FIG. 2 (b), within the thickness of the through transparent window. When the half mirror 3 is attached, the confirmation target side M
Since the real image 6 is provided on the interior material 81 facing the half mirror in the interior material of the through transparent window leading to, the upright of the real image 6 which is visible only to the person M to be confirmed on the half mirror 3 part. A virtual image 9 is formed.

For example, a name, a shop name, a slogan, a cautionary note, a slogan, or the like is written on the real image 6 in a wrong manner, or a landscape photograph or the like is attached and used.

The interior material 81 on which the real image 6 is provided is preferably a material exhibiting a strong light reflectivity, such as a metal foil, a metal plate, a resin plate, a plate glass, a decorative paper, etc. A very clear virtual image 9 can be obtained by processing into a mold or placing and fixing double-sided cut diamond type particles to form stable diffuse reflection, and drawing a real image on this surface in the opposite color of the interior material 81.

From the mounting position of the half mirror 3, the confirmer side N
If the entire interior material 82 of the through transparent window up to the above is made of a non-reflective color such as black or dark blue, the half mirror 3 is a virtual image of a small amount when the non-confirmer side N is seen through from the confirmer side N. It becomes a transparent glass shape that does not exist, making it easier for the confirmer to see through the visitors (confirmee).

The virtual image 9 formed in this way attracts the attention of the visitor who is the confirmed person, and at the same time blocks the see-through of the confirmation window by the visitor psychologically and physically, and is completely aware of the confirmer side N. The person who confirms can confirm in detail the appearance and the whole picture of the visitor in an extremely natural state.

<Example> FIGS. 1 (a), (b) and (c) show an example in which the present invention is attached to the door D at the entrance of a general house and used as a confirmation window for visitors.

(A) is a front view, (B) is a sectional view taken along the line AA of (A),
(C) is a perspective view before being attached to the door D.

In the figure, 1 is a see-through see-through window that allows one to see through the other, 2 is a dust-proof see-through glass that is attached to the front surface of the see-through see-through window 1, and 3 is a half mirror that is attached obliquely from one side to the other of the see-through see-through window 1. Reference numeral 4 denotes a hinge of a transparent shielding back cover 5 of the through transparent window 1, and 6 denotes a surface of an irregular reflection interior material 81 of the through transparent window 1 from the mounting position of the half mirror 3 to the person M to be confirmed. A real image, α is an angle formed by the diffused reflecting interior material 81 of the through transparent window 1 in which the real image 6 is written and the half mirror 3, and 9 is a virtual image.

A lens may be attached to the above-mentioned dust-proof transparent glass 2 on the front surface, if necessary.

In addition to the dust-proof effect, the see-through shielding back cover 5 also has an effect of preventing see-through of the interior of the visitor that is inevitably caused when the brightness of the confirmer side N is extremely high, such as when the external light at the entrance / exit is turned off. is there.

The real image 6 of this example is a diffuse reflection interior material 81 using aluminum foil.
On the surface of, the inventor's surname is written in dark blue, which is the opposite color.

FIGS. 2 (a) and 2 (b) show an example in which the present invention is used for a visitor confirmation window of a door of a general house.

This example is a circular confirmation window as shown in the figure.

In the figure, the same parts as those of the first example shown in FIG.

In this example, unlike the example of FIG. 1, the real image 6 is arranged on the surface of the interior material 81 facing the half mirror 3 above the through-transmission window 1.

The real image 6 is an example in which a red light emitting diode lamp (LED lamp) in which an expression is cut into a multi-sided cut diamond type is used and is expressed as "fire precautions" in red letters.

FIGS. 3 (a) and 3 (b) are modifications of the example of FIG. 1, and show an example of (a) in which light rays are projected from the bar light source L onto the irregular reflection surface of the interior material 81 of the see-through transparent window 1 on the side M of the person to be confirmed. This is an example of transparent (b).

The same parts as those in the example of FIG.

In this example, since light rays are projected or transmitted from above or below the diffuse reflection surface, unlike the examples in FIGS. 1 and 2, the diffuse reflection illuminance of the real image 6 is stable at a high level, and the visitor side (confirmed person). Even if the illuminances on the side M) and the confirmer side N are reversed, the see-through capability of the visitor is suppressed to the minimum and the confirming capability of the confirmer is maintained at the maximum, so that the see-through confirmation of the confirmer is possible. Regarding the projection of light rays, the same effect as that of the illustrated example can be obtained by projecting the light rays from the inner surface of the through transparent window 1 to the surface of the interior material 81, in addition to the illustrated example.

Reference numeral 10 is a hinge of the light source shielding lid 11.

In the present invention, the angle α formed by the real image 6 and the half mirror 3 is important, and when it is set to 45 degrees, the virtual image 9 is always an upright virtual image 9 parallel to the front and rear surfaces of the door D or the door D, and the through transparent window 1
Even if the line-of-sight 7 of the visitor who sees is up or down, the virtual image 9 is always upright, so that the virtual image 9 can be easily confirmed.

INDUSTRIAL APPLICABILITY The present invention can be used for the entrance of a house or the door of a doorway, the reception of an office, the door of a hotel, the door of a hospital room, etc., as in the above example.

<Effects of the Invention> The present invention has a surface of a highly diffused interior material arranged in the through transparent window extending from the position supporting the half mirror to the person to be confirmed in the through transparent window, or projecting illumination light. Alternatively, since the real image is arranged on the surface using the translucency, the half mirror draws a clear virtual image, and the virtual image deprives the attention and attention of the visitor, so that the visitor has no awareness of the confirmation window. Even if it does not occur, the confirmer can safely and easily check the visitor's appearance or the whole aspect, so it is possible to eliminate danger, prepare for appropriate response, etc. .
