Abstract

PURPOSE:To enjoy beauty due to a hue change by sharply changing a color appearing by changing the thickness of a shaped article or the direction of a glance to said shaped article by forming such a structure that the light passing through a polarizing plate passes through the shaped article composed of a light pervious material generating double refraction to further pass through the polarizing plate. CONSTITUTION:The light passing through the polarizing plate 6 of table stained glass 1 to become white polarized light passes through a shaped article (e.g., pattern) to be split into two polarized lights by double refraction. Subsequently, when these polarized lights pass through the same polarizing plate 6 or other polarizing plate 6, the lights having a certain wavelength in both polarized lights mutually interfere by a phenomenon called coloring polarization to be made intensive or weak mutually and the color corresponding to said wavelength appears. This color is sharply changed by changing the thickness of the shaped article or the direction of a glance to said shaped article.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an ornament whose color changes depending on the direction of the line of sight, such as an iridescent color.

Conventional technology and problems to be solved by the invention Traditionally, ceramics with a thin transparent glaze layer formed on the surface have been used as decorative items whose color changes depending on the direction of the line of sight, but their use has been limited to tiles, tableware, etc. Moreover, the color change was not very clear.

Means for Solving the Problems The present invention, as a means for solving the above-mentioned problems, provides a polarizing plate formed of a light-transmitting material that causes birefringence, such as an anisotropic crystal or cellophane tape, so that the light that passes through the polarizing plate The structure is such that the light passes through the shaped object, and then passes through a polarizing plate or another polarizing plate.

Functions and Effects The present invention has the above-mentioned configuration, and after the light beam that passes through the polarizing plate and becomes white polarized light is split into two polarized lights due to birefringence when passing through the modeled object, it is further divided into two polarized lights by the same polarizing plate or the other polarizing plate. When passing through a polarizing plate, due to a phenomenon called colored polarization, light rays of a certain wavelength in both sides of the light interfere with each other and strengthen or weaken each other, resulting in the appearance of a color corresponding to that wavelength. The colors change vividly by changing the thickness of the object and the direction of the line of sight toward the object, so by appropriately combining these conditions, you can enjoy the beauty of the changes in color.

Example Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 and 2 show a first embodiment in which the present invention is applied to a tabletop stained glass 1, in which one surface of a transparent support plate 3 made of synthetic resin or glass is By pasting a plurality of cellophane tapes 5 cut to length so that they partially overlap in the vertical and horizontal directions, a pattern 4 in which many squares and rectangles are aligned is formed, and these square parts In the rectangular portions, the overlapping layers of cellophane tape 5 have different thicknesses, and a pair of polarizing plates 6.6 are attached to the supporting plate 3 to which the cellophane tape 5 is attached. By gluing the parts, it is firmly fixed to both sides of the support plate 3,
A stained glass plate 2 is formed by fixing a pair of transparent protective plates 7.7 to the outer surfaces of both polarizing plates 6.6 so as to tightly sandwich them.
Its lower edge is fitted into a fitting groove 9 formed in the base 8, so that it is supported in an upright state.

When white natural light from the sun or a fluorescent lamp is applied from the back side of the tabletop stained glass l having such a configuration, the light beam passes through the polarizing plate 6 on the back side, becomes white polarized light, and passes through the support plate 3. At this time, since the cellophane tape 5 is stretched in one direction during the manufacturing process and has birefringence, this white polarized light is split into two polarized lights whose vibration directions are perpendicular to each other. When the polarized light from the book passes through the polarizing plate 6 on the front side, each vibration direction becomes the same, and due to a phenomenon called colored polarization, the specificity determined by the layer thickness of the cellophane tape 5 and the traveling direction of the light ray with respect to the cellophane tape 5. Rays of wavelength interfere with each other and strengthen each other, or
As a result, the colors corresponding to the wavelengths appear, creating a pattern 4 in which squares and rectangles of various colors are aligned, and even the same part changes to a different color when you change the viewing angle. You can enjoy the beautiful changes in color.

The color that appears in the cellophane tape 5 is due to the fact that the direction of the crystal axes of both side plates 6.6 is 4 with respect to the stretching direction.
It is darkest and clearest when it forms an angle of 5 degrees, and from this state, when the direction of the crystal axis of at least one of the deflecting plates 6 changes, the color gradually becomes lighter and unclear, and the color becomes darker and clearer than the cellophane tape 5. The color disappears when the direction of stretching coincides with or perpendicular to the stretching direction, and the color that appears differs depending on whether the crystal axes of the bidirectional plates 6.6 are in the same direction or perpendicular to the stretching direction, so the direction of the bidirectional plates 6.6 By changing the color, you can arbitrarily choose the color and its density.

In the first embodiment described above, the support plate 3 to which the cellophane tape 5 was attached and the two polarizing plates 6.6 were fixed together and supported on the base 8, but these were separated and the support plate 3 The cellophane tape 5 is fixed to the base 8, and each polarizing plate 6 is attached to a transparent plate (not shown), and these transparent plates are fixed at a position spaced apart from the support plate 3 of the base 8.
A space may be provided between the polarizing plate 6 and the polarizing plate 6.

Further, instead of being arranged parallel to the support plate 3, the polarizing plate 6 may be arranged obliquely to the support plate 3, or may be arranged curved in an arc shape.

Furthermore, instead of attaching the cellophane tape 5 to the support plate 3, a thin plate made of anisotropic crystal such as calcite may be attached, and in this case as well, the thin plate reduces birefringence. Because it occurs, colors appear due to colored polarized light.

As a modification of the first embodiment, if the thickness of the cellophane tape 5 attached to the support plate 3 is changed step by step, different colors will appear, like a spectrum divided into seven colors by a prism. It is possible to make a plurality of colors appear in sequence, and unlike conventional prisms, this prism has the advantage of being convenient for storage and transportation because it has a flat plate shape.

Next, a second embodiment in which the present invention is applied to an artificial flower 11 will be described based on FIG. 3. In the figure, 12 is a circular case made of transparent synthetic resin;
Inside, a stem 14 and a leaf I5 are formed with cloth, and on the stem 14,
The case 12 houses an artificial flower II in which petals 17 are formed by bending and fixing a plurality of cellophane papers 18 cut into a predetermined shape in a stacked manner.
On the inner periphery of the case 12, six rectangular polarizing plates 6 having the same height as the case I2 are connected and fixed in a regular hexagonal shape so as to surround the artificial flower 11, and when viewed from the side of the case 12, the back side When the polarized light that has passed through the polarizing plate 16 passes through the cellophane paper 18 of the petal 17, it is birefringent and split into two polarized lights, and then passes through the polarizing plate 16 on the front side, causing the petal I7 to appear colored due to the colored polarized light. At this time, since the cellophane paper 18 of the petal 17 was bent, the petal 17
Various colors appear like a rainbow, and the color of the petals 17 changes continuously by changing the position of the viewpoint.

In addition, the polarizing plates I6 are arranged such that the crystal axes of the parallel plates are perpendicular to each other, so that the artificial flower 1
1 can be made black, and in this case, there is an advantage that the color of the petals 17 stands out vividly.

As a modification of the second embodiment, cellophane tape or cellophane paper may be partially overlapped and sandwiched and glued between two polarizing plates, and the pieces cut into a predetermined shape may be used as petals. You may also do so.

4 and 5 show a third embodiment in which the present invention is applied to a decorative mirror 21, in which a plurality of sheets cut into a predetermined shape are attached to the reflective surface 24 of a mirror z3 fitted on a frame 22. cellophane paper 2
A butterfly pattern 27 is expressed by partially overlapping the mirrors 5 and pasting them with a transparent adhesive, and a polarizing plate 26 is closely adhered to the surface of the butterfly pattern 27. In this case, the polarized light that has passed through the polarizing plate 26 passes through the cellophane paper 25 and is reflected by the reflective surface 24 of the mirror 23, so that the polarized light passes through the cellophane paper 25 again and passes through the polarizing plate 26 again. Similar to the example, using colored polarized light, cellophane paper 2
The color appears depending on the thickness of the mirror 5 and the angle at which it is viewed, and in addition, in the areas of the reflective surface 24 to which the cellophane paper 25 is not attached, the polarized light that has passed through the polarizing plate 26 and reflected by the mirror 23 is the same polarized light. Since the light passes through the plate 26 and is not blocked unlike when two polarizing plates with their crystal axes oriented at right angles to each other are stacked, it can be used as a normal mirror 23.

FIGS. 6 and 7 show the present invention in a pendant 31.
In this fourth embodiment, mirrors 34 of the same shape are fixed to a main body 32 having a ring 33 projecting from the upper end for passing a chain (not shown), and the mirrors 34 are set at a slight angle to each other. A plurality of biased plates 36 are bonded together in a dish shape by bonding them to the outer circumferential edge of the mirror 34 to be fixed away from the reflective surface 37 of the mirror 34.
A plurality of cellophane tapes 35 are attached to the reflective surface 37 in the vertical and horizontal directions so as to partially overlap each other, and cellophane tapes 35 are also partially attached to the inner surfaces of the plurality of polarizing plates 36 corresponding to the mirrors 34. The pendant 31 is made by matching the thickness of the cellophane tape 35 on the polarizing plate 36 side with the thickness of the cellophane tape 35 on the reflective surface 37 side. The color is determined according to the thickness of the cellophane tape 35 on the polarizing plate 36 side, and since the cellophane tape 35 on the polarizing plate 36 side is separated from the reflective surface 37 of the mirror 34, when the viewpoint is moved, the color of the cellophane tape 35 on the polarizing plate 36 side changes. The image moves and the pattern 38 appears three-dimensional,
Furthermore, not only the angle with respect to the cellophane tape 35 changes, but also the cellophane tape 35 and the reflective surface 37 on the polarizing plate 36 side are changed.
The color changes in a complicated manner because the overlapping thickness of the side cellophane tape 35 changes, and the cellophane tape 35 of the reflective surface 37 is pasted through the part of the polarizing plate 36 where the cellophane tape 35 is not pasted. Even if you look at a part that is not there, if the image of the cellophane tape 35 attached to another part of the polarizing plate 36 is reflected on the reflective surface 37, color will appear in that part as well.

In addition, as another example using a mirror, one or more polarizing plates are placed on the front side of the mirror with a space between it and the reflecting surface, and cellophane paper is placed in the space in a three-dimensional manner. The formed object may be arranged.

FIG. 8 shows a fifth embodiment applied to a signboard 41 that is closely fixed to the wall of a building a.
The store name 4 is created by cutting a birefringent thin plate material 44 into the shape of a predetermined letter and attaching it to the reflective surface of a mirror 43 fixed to a frame 42, with the thickness changing for each letter.
5, and a polarizing plate 4 is attached to the frame body 42 so as to cover the reflective surface.
6 is fixed, and different colors appear in the letters of the store name 45 when sunlight is irradiated during the day and illumination light (not shown) is irradiated at night, and the color of the letters changes depending on the viewing angle. Since it changes, it has the advantage of creating a good impression by creating a beautiful appearance on the viewer, as well as attracting the attention of passersby and having a great advertising effect.

What is shown in FIG. 9 is a sixth embodiment applied to a signboard 51 that is attached to the wall of building B, and this signboard 5
1, a transparent support plate 53 is fixed to a rectangular frame 52,
Building name 5 due to the thin plate material 54 having birefringence on its surface.
5, and two polarizing plates 56 and 56 are fixed on both sides of the support plate 53, and light passes through the polarizing plate 56 on the back side, the thin plate material 54, and the polarizing plate 56 on the front side. Color appears in the letters of the name 55.

In addition to the above, a three-dimensional object such as a doll may be formed using a birefringent material and surrounded by a polarizing plate.

By applying the present invention to various articles other than those explained in the above embodiments, it is possible to enhance the decorativeness of the articles, and some examples thereof will be explained below.

Transmissive types that have polarizing plates on both sides of birefringent materials include sunglasses, covers for lighting equipment, transparent covers for the surface of watches, imitation jewelry, etc. Covers for sunglasses and lighting equipment are generally curved. Because of this, a large number of continuously changing colors appear, and the transparent cover of a watch can display colors by providing a light in the space between the cover and the dial, using this as a light source. For imitation gemstones, by embedding a large number of birefringent materials in different directions and thicknesses inside a transparent material, and arranging multiple polarizing plates to surround them, various colors can be created depending on the viewing angle. appears.

Reflective devices that place a birefringent material between the reflective surface of a mirror and a polarizing plate include book stands, brush holders, tiles, stone plates, buttons, brooches, etc. For buttons and brooches, the mirror, birefringent material, and polarizing plate can be stacked in order and buried inside a transparent body with a predetermined shape. good.

Objects that can be used with both transparent and reflective methods include accordion curtains, blind blades, electric fan blades, fans, underlays, plate-shaped objects such as rulers, and block-shaped objects such as paperweights. If the shape is partially or completely made of a transparent material, a birefringent material is attached to it, and a polarizing plate is attached to both sides to make it translucent. A mirror, a birefringent material, and a polarizing plate can be attached to the surface in this order, or they can be appropriately combined. A polarizing plate surrounding the periphery can be embedded, or a mirror, a birefringent material, and a polarizing plate can be sequentially attached to the outer peripheral surface.
