Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a display / decoration device that uses the reflection of a mirror surface that is composed of a part of a vertical cylinder.

[0002]

[Prior art]

 Conventionally, it is known that a vertical cylindrical convex mirror reflects an image of an insignificant pattern so that the image can be illusionary as a significant virtual image. The present inventor has made a new attempt to apply it to a display and decoration device using a concave mirror, and confirmed that it can find value as a molding art that combines the unexpectedness not possessed by a convex mirror and even more artistry. , Examination and consideration have been promoted.

In particular, when the above-mentioned conventional convex mirror is applied to an exhibition decoration device, since the convex mirror is provided so as to project to the front, a large space for installing the exhibition decoration device is required. Not only is it an obstacle, but it is relatively likely that other objects will come into contact with the concave mirror when it is overhanging forward, and as a result, the mirror surface will be scratched or dented and used as an exhibition decoration device. It was pointed out that there is a possibility that it will not be possible.

[0004]

[Problems to be solved by the device]

 The technical problem of the present invention is that it has a value as a molding art that has the unexpectedness of image reversal and the further artistic characteristic that the conventional display and decoration device using a convex mirror does not have, and that the convex mirror is used. Compared with the case, it is to provide an exhibition decoration device that does not require a large space for installation. Another technical problem of the present invention is to provide a display / decoration device in which there is no fear that the mirror surface will be scratched or dented by another object coming into contact with the concave mirror.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems, an exhibition decoration device of the present invention is composed of an image shown in an insignificant pattern and a concave mirror formed by a part of an inner surface of a vertical cylinder. The above-mentioned drawing is reflected by a concave mirror so as to be illusion as a significant virtual image different from the drawing.

In the display and decoration device, the drawing is displayed on at least one of the indoor floor and the ceiling, and the concave mirror is installed within the range in which the image of the drawing is totally reflected by the side wall surface inside the room. It is preferable to install it.

Further, it is appropriate to attach a protective transparent plate to the front surface of the concave mirror.

According to the display / decoration device having the above-mentioned configuration, an artistic decoration can be given to the place where the display / decoration device is installed by the drawing having the insignificant pattern. When reflected by a concave mirror, it is illusion as a significant virtual image with left and right reversed. In this way, in addition to the decorative property originally possessed by the decorative device, unexpectedness and artistry are added.

Further, since the concave mirror that constitutes a part of the inner surface side of the upright cylindrical shape is used, the mirror surface does not project forward, and therefore, unlike the conventional display and decoration device using a convex mirror. Not only does it not require a large installation space, but it is also possible to prevent scratches or dents caused by other objects coming into contact with the mirror surface.

Furthermore, by providing a protective transparent plate on the front surface of the concave mirror, it is possible to reliably prevent the mirror surface from being scratched or dented by another object coming into contact with the concave mirror.

[0011]

[Embodiment of the invention]

 Hereinafter, an embodiment of an exhibition decoration device according to the present invention will be described in detail with reference to the drawings. FIGS. 1 and 2 show a first embodiment of the present invention, and the exhibition decoration device is mounted on a table or the like. It shows the case where it is applied to an ornament to be placed.

This display and decoration device is composed of a mirror body 2 and a drawing 6 shown on the upper surface of the table 4. The mirror body 2 is configured by accommodating a concave mirror 10 formed of a part on the inner surface side of a vertical cylinder in a frame body 8. The front surface of the concave mirror 10 includes a transparent plate 12 made of glass. Is attached. The transparent plate 12 is for protecting the concave mirror 10 from scratches and dents caused by contact with other objects.

In the display and decoration device, as shown in FIG. 2, the image 6 shown in an insignificant pattern which is visible in the range shown by the broken line in direct view is reflected by the concave mirror 10 and is significant in the range shown by the alternate long and short dash line. It is illusionary as a virtual image 6 ′ showing the shape. The above-mentioned unintentional shape has no meaning, or even if it has it, it seems that the picture that is supposed to be illusion with the original concave mirror is extremely deformed, and in some cases it seems to be pseudo-associating with other things. A significant shape means a shape that has a unique shape.

Explaining in more detail with reference to FIG. 3, for example, the image of the image 6 on the upper surface of the table 4 represented by the graphic ABCD is reflected by the concave mirror 10 and the image is generated by the action of the concave mirror 10. 6 and is illusion as a virtual image 6 ′ represented by an inverted quadrilateral A′B′C′D ′. That is, as shown in the figure, the light incident on the concave mirror 10 from each top of the figure ABCD parallel to the optical axis L is reflected through the focal point F at a reflection angle equal to the incident angle at the incident point. On the other hand, on the other hand, the light from each top of the figure ABCD incident through the center of curvature O of the concave mirror 10 has a reflection angle of 0 °, and therefore is reflected in the same direction as the incident angle but in the opposite direction. Then, the intersections of the reflected lights on the concave mirrors at the respective apexes, and the intersections obtained at the arbitrary points between the apices of the figure ABCD in the same manner are the quadrangle A'B'C'D '. Is a virtual image 6 '. Therefore, a person who views the image 6 on the front surface of the concave mirror 10 sees the virtual image 6 ′, that is, the insignificant image 6 as a significant shape by the concave mirror 10.

According to the display / decoration apparatus of the first embodiment having the above-mentioned configuration, the artistic decoration can be given by the image 6 having an insignificant pattern, and the image 6 is made by the concave mirror 10. By reflecting it, it is illusion as a significant virtual image 6'in which the left and right are reversed, so that in addition to the decorativeness originally possessed by the display and decoration device, unexpectedness and artistry are doubled.

Further, since the concave mirror 10 forming a part of the inner surface side of the upright cylinder is used, the mirror surface does not project forward, and therefore, it is like a conventional display accessory with a convex mirror. Not only is it possible to save space, but it is also possible to prevent the concave mirror 10 from being scratched or dented by another object coming into contact with it.

Further, since the protective transparent plate 12 is attached to the front surface of the concave mirror 10, it is possible to surely prevent the concave mirror 10 from being scratched or dented by the contact of another object with the concave mirror 10. it can.

Next, FIG. 4 shows a second embodiment of the present invention, showing a case where the display and decoration device is applied to a lobby such as a hotel or a building. In the figure, reference numerals 20, 22, and 24 denote side wall surfaces, floor surfaces, and ceilings of a lobby such as a hotel and a building, and 26A and 26B respectively show drawings on the floor surface 22 and the ceiling 24.

The concave mirror 10 is installed within a range in which the images of the drawings 26 A and 26 B are totally reflected by the side wall surface 20, and the front surface of the concave mirror 10 is occupied by a passerby. A transparent plate 12 is attached to protect the concave mirror 10 from scratches and dents caused by the contact with each other.

It should be noted that it is advantageous to use an indoor corner for mounting the concave mirror 10 because the concave wall 10 cannot be recessed particularly on the side wall surface 20.

In the second embodiment, the floor surface 22 and the ceiling 24 are shown as a form in which the images 26A and 26B respectively displayed in an insignificant pattern are displayed, but the present invention is not limited to this. It is also possible to show the drawing only on the surface 22 or only on the ceiling 24. It is the same as described above with reference to FIG. 3 that the unintentional drawings 26A and 26B are illusions as significant virtual images 26A 'and 26B'.

Further, since the concave mirror 10 which constitutes a part of the inner surface side of the vertical cylinder is used, it does not protrude from the side wall surface 20 inside the house, and thus it does not interfere with passersby. Not only that, but there is no risk that a passerby may accidentally come into contact with it, causing scratches or dents.

Further, since the transparent plate 12 for protection is attached to the front surface of the concave mirror 10, it is possible to more reliably prevent the concave mirror 10 from being scratched or dented due to an accidental contact of a passerby. can do.

Since the other configurations and operational effects of the second embodiment are substantially the same as those of the first embodiment, the same portions or corresponding portions will be denoted by the same reference numerals and the description thereof will be omitted. To do.

[Effect of the invention]

 According to the display and decoration device of the invention detailed above, an artistic decoration can be added to the place where the display and decoration device is installed by a drawing consisting of an insignificant pattern. By reflecting it, it is illusion as a significant virtual image in which the left and right sides are reversed, so in addition to the originality that the display and decoration device originally possesses, unexpectedness and artistry are doubled, which in turn has value as a sculptural art. A display and decoration device can be provided.

Further, since the concave mirror which constitutes a part of the inner surface of the upright cylinder is used, the mirror surface does not project forward, and therefore, unlike the conventional display and decoration device using the convex mirror. Not only does it not require a large installation space, but it is also possible to prevent scratches or dents caused by other objects coming into contact with the mirror surface.

Furthermore, by providing a protective transparent plate on the front surface of the concave mirror, it is possible to reliably prevent the mirror surface from being scratched or dented by another object coming into contact with the concave mirror.
