Description

[Detailed description of the invention] The present invention relates to a three-dimensional mark.

Conventional three-dimensional marks have been created by actually forming a three-dimensional uneven surface on the surface of a substrate, but these have had the problem of not only becoming unsightly due to the adhesion of dust and the like, but also increasing the thickness of the substrate.

There is also a three-dimensional mark by forming a concave surface showing a mark on the back side of a transparent resin such as acrylic, coloring the concave surface, and embedding it in the substrate. However, the thickness of the substrate is required.

SUMMARY OF THE INVENTION In view of the above conventional problems, it is an object of the present invention to provide a three-dimensional mark that does not cause unevenness on the surface of a product substrate and can be used even on a very thin substrate.

However, the three-dimensional mark of the present invention has a recess on the substrate surface,
In the recess, a display layer for displaying a mark, a lens layer for giving a three-dimensional effect to the mark, and a layer 11 in the recess are arranged in order from the bottom side.
It is constructed by arranging transparent resin layers in a laminated state to seal 0.

The present invention will be explained below with reference to illustrated embodiments.

FIG. 1 shows a first embodiment of the present invention, in which a concave portion 11 is formed in the surface of a substrate 1 made of vinyl chloride resin, ABS resin, etc. without being tapered.

Then, in the recess 11, a mark serving as a display layer is printed from the bottom surface, and a mark serving as a display layer is printed on the IcEp printing sheet 1, and a transparent resin layer 3L15, which is a resin molded body serving as a lens layer, and a transparent resin layer sealing these in the recess 11 are added. 4 are sequentially layered in 11'i layers to form a three-dimensional mark.

The above-mentioned printed sheet 2 is created, for example, by the following procedure. 4-
That is, a three-dimensional object, which is the original form of the mark, is displayed on photographs from two directions, left and right, and each photograph is divided into elongated ribbon-like pixels.

Thereafter, the ribbon-like pixels of the left and right photographs are alternately arranged to form a printing sheet 2.

As shown in the figure, the lenticular plate 3 has a large number of arc-shaped convex surfaces 31 formed on one surface (the upper surface in the figure), and each convex surface 31 functions as a lens. When the printed sheet 2 is brought into close contact with the other surface of the lenticular plate 3 (bottom surface in the figure) and viewed from above the figure, which is the lens surface side, each line of sight of the left eye and the right eye is connected to each convex lens. Print sheet 2 through 31
It focuses on the left and right pixels arranged alternately above. As a result, a three-dimensional image is restored from the flat printing sheet 1.

The three-dimensional mark shown in the figure is made by inserting the above-mentioned wrench, the assembly of the equal plate 3 and the printing sheet 2 into the recess 11 of the substrate 1, and then applying a transparent resin 4 such as acrylic on the same surface as the substrate surface. After injecting the resin 4 as shown in FIG.

As described above, the three-dimensional mark of the present invention is produced by sealing a lenticular plate with a printing sheet in close contact with a transparent resin in a recess of a substrate. It does not cause unevenness on the substrate surface, and the thickness of the joined body of the printing sheet and lenticular plate is 1 m111 or less.
It is possible to install it even on very thin substrates. moreover,
The three-dimensional mark of this embodiment allows the three-dimensional display of fairly complex patterns and landscapes.

FIG. 2 shows a second embodiment of the present invention. Since t = b, a Fresnel lens 3' made of a resin molded body is disposed in the recess 11 of the substrate 1 with the lens surface facing downward. A colored metal such as chromium or tin is vapor-deposited on the lens surface so as to form a mark to form the display layer 2'. and,
The recessed opening above the Fresnel lens 3' is sealed with transparent resin 4.

The Fresnel lens 3' is formed by dividing the lens surface of a normal concave-convex lens on a flat plate, and has the same function as a normal concave-convex lens, yet the lens thickness can be made extremely thin.

Therefore, when the mark drawn by vapor-deposited metal is viewed from above the figure through the Fresnel lens 3', it can be visually recognized as a three-dimensional mark curved forward or backward.

Even with the structure of this embodiment, like the first embodiment, no unevenness occurs on the substrate surface, and moreover, it can be provided even on a very thin substrate.

J3. In each of the above embodiments, it is of course possible to use a colored transparent resin.

As described above, the three-dimensional mark of the present invention includes a display layer that displays the mark in a recess formed on a substrate, a lens layer that gives a three-dimensional effect to the mark, and a transparent resin layer that seals the opening of the recess, sequentially from the bottom side. By arranging the 81I layers, a three-dimensional mark with a good appearance and a small shape is realized, and it is particularly suitable for use in 1) diagonal moldings with heavy marks, horn pads of steering wheels, etc.
