Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to the improvement of a lighting fixture whose main material is a synthetic resin thin plate.

(Conventional technology and its problems) Lighting equipment in which a thin synthetic resin plate is fitted into a window formed on a frame body of a desired shape requires a lot of work in manufacturing the frame body and fitting the thin synthetic resin plate into the window hole. In addition to being expensive, the illumination efficiency in the skeletal body portion is poor. Therefore, as an alternative to such lighting equipment, the present applicant has proposed a lighting equipment whose main body is formed by bending a thin synthetic resin plate into a frame shape, as disclosed in Japanese Utility Model Application Publication No. 52-69884. However, such lighting equipment has problems with shape retention, and in order to enhance the decorative effect, it is difficult to use ordinary laminated decorative boards, which are made by laminating multiple synthetic resin sheets adhesively laminated together as a thin synthetic resin material. In this case, a delamination phenomenon is observed in the folded portions, and these folded portions become unsightly and aesthetically problematic, so they are hardly put into practical use.

(Means for Solving the Problems) The present invention aims to utilize the features of a lighting fixture that is made by bending a thin synthetic resin plate into a frame shape and have creases as the main body, while also addressing the drawbacks of shape retention and aesthetics. This was completed with the aim of solving the above problem and creating a lighting fixture that has the characteristically elegant appearance of washi paper but can also be wiped with water or washed with water. A circumferential body member is made by laminating a foldable decorative synthetic resin material made by laminating transparent synthetic resin sheets on both sides of a decorative core paper with elasticity, and folding it into a frame shape through the folds. It is fitted and adhered to a shape-retaining groove frame portion which is connected to the periphery of the hanging member and whose cross-sectional shape is approximately the same as that of the circumferential drum member, and at the lower end of the circumferential drum member, the cross-sectional shape is approximately the same as that of the circumferential drum member. It is characterized by fitting and bonding equal frame-shaped shape-retaining groove members.

Embodiment Next, the present invention will be described in detail with reference to the illustrated embodiment.The upper end of the cap 5 is fitted into a groove of a shape-retaining groove frame portion 8a that continues to the periphery of the hanging member 8. The circumferential body member 5 is a decorative core paper 1 made of Japanese paper or chemical fiber paper made into Japanese paper and having a wall thickness of about 0.2 to 0.6 mm, and has thick walls on both sides. Thermoplastic transparent synthetic resin thin plates 2a, 2b such as vinyl chloride resin sheets with a diameter of about 0.1 to 0.3 mm are bonded using vinyl chloride resin, which is usually used for bonding these sheets.
The material is a bendable band-shaped decorative synthetic resin base 3 laminated by heat-pressing through an extremely thin coating layer of a vinyl acetate resin copolymer adhesive, and a blade shape made by heating this material is used. The circumferential body member 5 is bent into a rectangular frame-shaped main body with a fold line pattern through a large number of folds 4 extending in the width direction formed by
A shape-retaining groove member 6 having a narrow width and substantially the same cross-sectional shape as the circumferential body member 5 is fitted and bonded to the lower end of the member 5 for reinforcement. In addition, the material of the shape-retaining groove material 6 may be metal or synthetic resin as long as it has a shape-retaining effect.
Further, 7 is a decorative pattern provided on the decorative core paper 1 as necessary.

(Function) When a light bulb constructed in this way is used with a light bulb inside, it has good illumination efficiency because there is no skeleton extending in the vertical direction. However, the circumferential body member 5 is a decorative synthetic resin base 3 in which transparent synthetic resin thin plates 2a and 2b are laminated on both sides of a decorative core paper 1 made of Japanese paper or Japanese paper-like chemical fibers.
During the day, the decorative core paper 1, which has a Japanese paper-like appearance, is visible to the outside through the transparent synthetic resin thin plate 2 on the front side, giving it an appearance rich in Japanese atmosphere. On the other hand, when the light bulb is turned on at night, the fiber structure unique to Japanese paper of the decorative core paper 1 is exposed to the transparent synthetic resin thin plate 2 on the front side.
It shines beautifully due to the light rays transmitted through it, and since the circumferential body member 5 has a fold line pattern formed by folding the decorative synthetic resin base 3 into a frame shape through the folds 4, 4 and its vicinity, the transmission direction of the light ray changes and shadows are formed, creating an extremely interesting lighting effect as a whole.
Furthermore, the decorative core paper 1 is made of transparent synthetic resin thin plates 2a, 2.
Since the decorative core paper 1 is located between B and B, the decorative core paper 1 will not be damaged even if subjected to friction or other external influences, and can also be wiped or washed with water, and will maintain a beautiful appearance for a long period of time. Moreover, since the decorative core paper 1 forming the intermediate layer of the decorative synthetic resin base 3 is made of stretchable Japanese paper or Japanese paper-like chemical fiber paper, it can be folded with the folds 4 facing either the front or the back. Even when formed or sharply bent, as shown in FIG. The transparent synthetic resin thin plate 2 extends along with the stretching of the resin thin plate 2a, and the inner side that contacts the inner transparent synthetic resin thin plate 2b which is contracted.
The material becomes denser as it follows the shrinkage of b, and no delamination phenomenon is observed on the inside as well as on the outside. Since no opaque lines are formed, the appearance of the folded portion is not spoiled, and the upper and lower edges of the circumferential body member 5 are formed into shape-retaining groove frame portions 8a whose cross-sectional shape is approximately the same as that of the circumferential body member 5. Since the shape is retained by the frame-shaped shape retaining groove member 6, there is no deformation of the circumferential body member 5 even if no skeleton is used.

(Effects of the invention) As is clear from the above description, the present invention is formed by folding a decorative synthetic resin base made by laminating foldable transparent synthetic resin sheets on both sides of a stretchable decorative core paper. Because the circumferential body member is used, it can be wiped and washed with water despite having the unique appearance of washi paper, and it also eliminates the interlayer gaps that can be seen at the creases when folding an ordinary laminated synthetic resin board. There are no marks due to peeling, and the appearance is good, and the upper and lower edges of the circumferential body member are reinforced by the shape-retaining groove frame and the shape-retaining groove material, which have approximately the same cross-sectional shape as the circumferential body member. So,
It can be used for a long time without deformation of the surrounding body parts.
While the structure is simple and can be provided at low cost, it takes advantage of the advantages of conventional lighting fixtures, which are mainly made of folded synthetic resin sheets bent into a frame shape, and eliminates the disadvantages of shape retention and aesthetics. This lighting device has great practical value as it solves the problems of the above.
