Abstract

<P>PROBLEM TO BE SOLVED: To obtain a visual sense effect for making out an object transparent or translucent. <P>SOLUTION: Parallel light entering an incident plane of light is reflected on object surface mirror 1 (102), a side mirror 1 (101), a side mirror 2 (107), and an observation surface mirror 2 (106), and reaches an observer. Since the parallel light is presented to the observation surface mirror while information of the traveling direction of the incident light is held, an object placed in shielding space (104) of a central part seems to disappear from the field of view. By bypassing the light by being reflected in parallel on the periphery of the light shielding object, the transparent effect can be obtained. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  Technical fields related to product design effects, protective color effects that hide from the surrounding environment, and hidden haze effects.

  Conventionally, a protective color effect has been produced by coloring colors and patterns according to the surrounding environment. Also, according to Patent Document 1 below, a technique for creating a hidden haze by forming and displaying a three-dimensional image of a target image on the line of sight is disclosed. However, it is difficult to function well when a large number of objects with different distances such as a background scene must be displayed.

JP 2006-319932 A

  In order to realize a hidden haze effect that makes the contents appear to be non-existent or to be visually perceived as a transparent object, the position and size of the image perceived from the hidden haze surface can be changed if the position of the observer changes with respect to the hidden haze. It is desirable to display on the line of sight connecting the position of the observer and the position of the object, and to change the size so as to be the size on the line of sight. There is a need for a hidden haze effect in which the display position, size, and the like appropriately change according to changes in the position of the observer, and its production means.

  The first means is the object side mirror surface that receives parallel incident light from the object and the reflected light, or the side surface that receives the reflected light or reflected light (hereinafter simply referred to as “reflected light”). Side mirror surface 1, a side mirror surface 2 that reflects the reflected light of the side mirror surface 1 to the observation surface mirror, and an observation mirror surface that reflects the reflected light to the observer side are provided, and the position and angle of these mirror surfaces are determined by the observer. In the transparent visual effect production method combined so that the object can be visually recognized by the eyes, the objective mirror surface and the observation mirror surface are formed on the side surface of the polygonal cylinder, and the side mirror is provided in a direction parallel to the objective mirror surface and the observation surface mirror. It is characterized by that.

  By reflecting incident light from the incident side around the shield and reflecting it to the observation surface, the scene on the incident side is reflected on the observation surface. During this detour, the light can be emitted from the observation surface while preserving the light traveling direction information to the incident surface by passing through a detour passage composed of parallel reflecting surfaces on both sides. As the image of the surface is projected as it is, the object in the shielded space that has been detoured appears to have disappeared. However, it will appear far away by the extra distance that the light has detoured. Further, since the reflecting surface of this means is flat, the positional relationship of the images is matched only in the horizontal direction. For example, if the viewing angle is limited to only near the horizontal, the vertical direction of the means can be observed as close as possible to the original image when the viewing angle is limited to near horizontal.

  When the second means assumes two polyhedrons, that is, a polyhedron 1 and a polyhedron 2 configured to include a polygon that is congruent with the objective mirror surface and the observation mirror surface of the polyhedron 1, the objective mirror surface on the surface of the polyhedron 1 and By forming the observation mirror surface, and further arranging the polyhedron 1 in the polyhedron 2 so that the vertices of the polyhedrons 1 and 2 are arranged in a straight line from the center point of the polyhedron 2, the side mirror forms a mirror surface on the inner surface of the polyhedron 2. The incident light inlet is a truncated polyhedron cut surface (cut surface A) obtained by cutting the polyhedron 2 along a plane including one apex (vertex a) of the polyhedron 1, and the reflected light exit is also the apex a. It is characterized by comprising a polyhedron 1 and a diagonal truncated polyhedron that are reflected in a viewer direction from a cut surface (cut surface B) cut along a plane including diagonal vertices (vertex b) across the polyhedron center point.

  In this means, since the reflecting surface is three-dimensionally reflected, it is reflected in the vertical and horizontal directions, so that the vector information of the light in the vertical direction as well as the horizontal direction is stored and the positional relationship of the image displayed on the observation surface is accurately determined. Can be reproduced.

  A third means is a transparent vision characterized in that a light source is provided in a shielded space surrounded by a reflecting surface, and lighting or extinguishing is controlled, or incident of light from the outside to the shielded space is controlled. Effect production method and product.

  In particular, in the second means, since the periphery is surrounded by a total reflection surface and no light is incident on the shielding portion, the object in the shielding space looks transparent as it is. However, by turning on the light source inside, the inside and the scenery from the back overlap and appear translucent. Further, if the first means also closes the shielding portion, light does not enter and the inside becomes transparent as well. By controlling the illuminance of this shielded space, things in the shielded space become transparent or translucent, and in addition to on / off control, the intensity of the illuminance controls how these images are mixed and how they appear Changes.

  By constructing the reflecting surface with a mirror, the central part that bypasses the optical path can be seen as if it were transparent. In addition, when the incident parallel light is totally reflected using a prism on the reflecting surface and diverted, the light from the object at the center is incident from the air to something with a high refractive index such as glass or acrylic, so that the observation surface Break through. As a result, the background image and the center image appear to overlap, so the object appears to be translucent. A transparent or translucent visual effect is obtained.

  1, 2, 3, 4, 5, and 6 are explanatory diagrams for explaining the principle of the present invention, and are used in common in the following embodiments. FIG. 1 shows an example in which plane mirrors are combined. 101 is a side mirror 1, 102 is an objective mirror 1, 103 is an objective mirror 2, 104 is a concealing space, 105 is an observation surface mirror 1, 106 is an observation surface mirror 2, and 107 is a side mirror 2. FIG. 2 is an example in which the side surface portion of FIG. 1 is extended. 201 is a side mirror, 202 is an objective mirror, 203 is a side wall, and 204 is an observation mirror. In FIG. 3, the reflecting surface is constituted by total reflection such as transparent glass. Reference numeral 301 denotes a prism portion, 302 denotes an incident surface, 303 denotes a shielding space, and 304 denotes an observation surface. FIG. 4 is an extension of the side of FIG. Reference numeral 401 denotes an incident surface, 402 denotes a prism portion, 403 denotes an observation surface, and 404 denotes a shielding space. FIG. 5 shows a prism composed of two truncated tetrahedrons on the outside and two tetrahedral cavities on the inside. Reference numeral 501 denotes an incident surface, 502 denotes a prism portion, 503 denotes a shielding portion, and 504 denotes an observation surface. FIG. 6 is an extension of the side of FIG. Reference numeral 601 denotes an incident surface, 602 denotes a prism portion, 603 denotes a shielding space, and 604 denotes an observation surface. Equation 1, Table 1, and Table 2 show the refractive index and angle range of the prism portion. θ is a value obtained by subtracting the incident angle from 90 degrees as an angle formed between the light beam and the reflecting surface. α is a critical angle with air, β is a critical angle with silicon oil having an absolute refractive index of 1.4, and ω is a critical angle with water.

  In recent years, crimes in public toilets have increased. The main reason is that there is a risk of privacy infringement, so it is difficult to install a security camera in the toilet and it is often isolated from the outside, and in public toilets there are many blind spots around the toilet. It is done. Therefore, there is a need to allow the inside of the toilet building to be viewed from the outside, and to reduce the blind spot at the outer periphery of the toilet. 1 and 2 are top sectional views of a public toilet when applied to a toilet as an example of the present invention.

  The incident light from the objective mirror side is detoured by the mirror and reflected while keeping the information of the light traveling direction on the observation surface side. Disappears from view. However, since the reach distance of light is extended, it appears to be far from the actual position. By placing the toilet in the concealed space (104) in FIG. 1 or in the center surrounded by the mirror in FIG. 2, side mirrors (101, 107, 201) and objective mirrors (102, 103, 202) and the observation path mirror (105, 106, 204) and the rear of the objective mirror (102, 103, 202) can be easily monitored from the front observation plane. By installing a surveillance camera on the observation side, the surroundings and the back of the toilet are constantly monitored, leading to crime prevention. Moreover, the movement of the person in the toilet can be monitored at a minimum by setting the position of the upper face of the toilet as an opening.

  This system can be used for elevator doors, pillars, storage, tents, etc., in addition to public toilets. It can block or hide things that obstruct vision such as pillars and elevators.

  FIG. 7 is a side sectional view showing an example applied to a vase. 701 is a prism portion, 702 is a shielding space, 703 is an observation surface, 704 is a hollow portion of the shielding space, and 705 is a water surface.

  It is the vase which comprised the prism part (301,402) of FIG. 3 or FIG. 4 with the glass wall surface (701). The shielded space (702) corresponds to (303, 404) and contains water and flowers. In the cavity (704) of the shielding space, the light incident on the glass from the incident surface is totally reflected at the boundary surface between air and glass, and an image is displayed on the observation surface (703). Further, the light from the flower stem in the cavity (704) is displayed on the observation surface (703) for incidence from the air to the glass. Since the flower stems are displayed overlapping the background from behind, the visual effect is as if the flower was only translucent. Further, in the area below the water surface (705) containing water, water and low refractive index glass do not cause total reflection, so the flower stem is displayed as the same stem as the real one. An advertising tower using a translucent doll can be made by putting a doll into and out of the shielding portion of this embodiment, and can also be used for a display for display and accessories. It can also be applied to containers such as trash cans and pen stands.

  FIG. 8 is a side sectional view showing an example applied to a table clock. Reference numeral 801 denotes a table, 802 denotes a prism portion, 803 denotes an observation surface, and 804 denotes a shielding space.

  In this embodiment, an illuminated timepiece is provided in the shielding space (503, 603) of the prism shown in FIG. 5 or FIG. 6 and the dial faced toward the observation surface (504, 604). The prism portion (802) corresponds to 502 or 602, the observation surface (803) corresponds to 504 or 604, and the shielding space (804) corresponds to 503 or 603. In this embodiment, the dial of the watch looks translucent like the previous embodiment. Further, by using the high refractive index glass or cubic zirconia shown in Table 2 for the prism portion, the reflecting surface angle of the prism can be increased as shown in the table, and the thickness can be reduced. In addition, by turning on the lighting at the set time, the clock becomes transparent and semi-transparent along with the sound so that the time can be notified. In addition, when putting an object to be made to appear translucent together with water in the shielding space (804), a prism material having a value of ω of Table 2 exceeding 45 degrees is used, and when sealing with silicon oil, β Use the one whose value exceeds 45 degrees.

  In this embodiment, an example in which FIG. 5 or FIG. 6 is applied to a transparent food is shown.

  By sealing transparent or translucent food such as agar, gelatin, straw, rock sugar, salt, etc. in the prism part (502, 602) and other solid food in the shielding space (503, 603) together with air, It can appear to be translucent. In the case of a food having a critical angle α of less than 45 degrees in Table 1, a translucent effect can be obtained by setting the angle of the reflecting surface with respect to the incident light of the prism to a critical angle θ or less. A food having a critical angle α of 45 degrees or more can obtain the same effect by configuring it in the range of not less than the minimum θ and not more than the maximum θ in the table. For materials not listed in the table, the value of the minimum θ can be obtained by Equation 1.
