Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a decorative synthetic resin board mainly used for lighting equipment and partitions.

(Prior Art) Conventional decorative synthetic resin plates of this kind are usually made by printing various patterns on the surface of a transparent synthetic resin plate, but they are monotonous and lack interest. Therefore, it has been proposed that a raised pattern is formed on the surface of a transparent synthetic resin thin plate to give a three-dimensional effect and to refract and reflect light. (For example, Japanese Utility Model Application Publication No. 55-118725) (Problems to be solved by the invention) However, forming a raised pattern on the surface of a thin synthetic resin plate requires complicated steps, and it is difficult to mass-produce it easily. Not only is it difficult to do this, but the refraction and reflection of the light rays becomes completely disordered, causing a sense of dazzle to the eyes.

(Means for solving the problem) The present invention was completed with the aim of producing a decorative synthetic resin board that does not have the above-mentioned drawbacks. It is characterized by having a series of tortoiseshell-shaped grooves continuously and shallowly bored on the surface of a transparent synthetic resin thin plate, and in addition to providing countless minute irregularities on the back side of the synthetic resin thin plate. Below, the illustrated embodiment will be described in detail.

(Example) Reference numeral 1 is a thin synthetic resin plate made of transparent or translucent vinyl chloride resin, acrylic resin, etc. and has a translucent property and has a thickness of about 0.5 to 2 mm. A tortoise shell shaped groove 3 is continuously formed to a depth of about 0.1 to 0.3 mm, with the parallel sides being twisted thread grooves 5, which are continued with shallow grooves 2, and the thin synthetic resin plate Countless fine irregularities 4 are provided on the back surface of 1. In the figure, reference numeral 6 denotes a transparent synthetic resin film layer which has better heat resistance than the synthetic resin thin plate 1 and is layered on the surface of the synthetic resin thin plate 1 as required.

When constructed in this way, it can be cut to the required size and framed to be used as a lighting fixture or partition. All of the hexagonal grooves 3 that are continuously and shallowly bored on the surface of the thin plate 1 can be seen through as a unique geometric pattern, and the twisted thread-like grooves 5 are arranged on the left and right sides of each hexagonal groove 3. Unlike Shallow Structure 2, which followed this pattern, it shines in a zigzag pattern under the complex reflection of light, and the whole exhibits an extremely interesting and unique decorative effect. In addition, the light-transmitting synthetic resin thin plate 1 does not cause any glare to the eyes due to its matte finish due to the countless minute irregularities 4 provided on the back surface, and it is not possible to clearly see through objects on the back surface side from the front surface side. , which can exhibit favorable effects as lighting equipment or partitions. Moreover, in order to continuously and shallowly drill the tortoiseshell-shaped grooves 3 on the surface of the synthetic resin thin plate 1 as described above, it is necessary to prepare an inexpensive wire mesh having a similar hexagonal-shaped mesh and use this as a mold. It has the great advantage of being easily mass-produced.

(Effects of the invention) As is clear from the above description, the present invention has a continuous shallow hexagonal groove on the surface of a transparent synthetic resin thin plate that can be seen through as a continuous geometric pattern with a unique decorative effect. By having holes and countless fine irregularities on the back surface, it can be used effectively mainly for lighting equipment and room partitions, and eliminates the drawbacks of known decorative synthetic resin boards of this type. It has extremely great practical value.
