FIG. 1 is a plan view of an illuminating device for an elevator cab in Embodiment 1 of the present invention, FIG. 2 is a cross-sectional view taken along the line A-A in FIG. 1 of Embodiment 1 of the present invention, and FIG. FIG. 3 is a detailed view of part B in FIG. In the figure, a resin lighting plate 2 is suspended from an elevator cab ceiling 1 in parallel with the cab ceiling 1 via a hanging tool 3, and this cab ceiling 1 and a resin lighting plate. 2, a plurality of light sources 4 for illuminating the interior of the car are arranged. The resin illuminating plate 2 installed above the elevator cab is provided with a structure, coloring, processing, and the like that cannot be seen from above from below. The shape of the light source 4 installed on the cab ceiling 1 and the structure above the resin lighting plate 2 cannot be recognized. The resin lighting plate 2 is provided with a plurality of light transmission holes 2a having a substantially rectangular shape at an arbitrary position over the entire surface thereof. The transparent acrylic block 5 provided in each of the light transmitting holes 2a has a width that is slightly narrower than the width of the light transmitting hole 2a, and has a substantially rectangular parallelepiped lower portion that becomes narrower as it goes downward. A substantially rectangular parallelepiped upper portion having a width larger than the width of the light hole 2a, and a part of the lower portion projects below the resin illumination plate 2 through the light transmitting hole 2a. Thus, the upper and lower surfaces of the transparent acrylic block 5 and the upper surface which is a non-design surface of the resin lighting plate 2 are welded and fixed so that the translucent hole 2a is closed from above. Further, on the upper upper surface and the upper side surface of the transparent acrylic block 5, the shape of the light source 4 installed on the car ceiling 1 via the transparent acrylic block 5 and the structure above the resin lighting plate 2 by the passenger in the car room are provided. A light diffusing portion 5a that has been painted or treated so that it cannot be recognized is provided.

次に、このかご室の照明装置の製造方法について説明する。
先ず、透光孔２ａが設けられた樹脂製照明板２に、この透光孔２ａを塞ぐように透明アクリルブロック５を挿入して、樹脂製照明板２の非意匠面と透明アクリルブロック５の上部下面とが接触するように配置する。次に、樹脂製照明板２と透明アクリルブロック５の接触部を加熱して、樹脂製照明板２と透明アクリルブロック５とを溶着固定する。なお、樹脂製照明板２上面と透明アクリルブロック５の上部下面とを溶着するには、樹脂製照明板２及び透明アクリルブロック５の溶着部を予め加熱しておき、透明アクリルブロック５を樹脂製照明板２の透光孔２ａに嵌め込むことで溶着する方法も考えられる。その後、透明アクリルブロック５の上部上面及び上部側面に、光拡散部５ａを生成する。光拡散部５ａを生成するには、例えば、無数のビーズが塗料の中に入れられたビーズ入りクリア塗装等の光拡散塗装を透明アクリルブロック５の上部上面及び上部側面に塗布するものがある。また、ショットブラストによるなし地仕上げ等の光拡散処理を透明アクリルブロック５の上部上面及び上部側面に施すものもある。なお、ショットブラストによるなし地仕上げによって光拡散部５ａを生成する場合には、予め透明アクリルブロック５の上部上面及び上部側面になし地仕上げを施しておき、光拡散部５ａ生成後の透明アクリルブロック５を樹脂製照明板２に配置して溶着することも可能である。 Next, a method for manufacturing the illuminating device for the cab will be described.
First, the transparent acrylic block 5 is inserted into the resin lighting plate 2 provided with the light transmitting hole 2a so as to close the light transmitting hole 2a, and the non-design surface of the resin lighting plate 2 and the transparent acrylic block 5 are formed. It arrange | positions so that an upper lower surface may contact. Next, the contact portion between the resin illumination plate 2 and the transparent acrylic block 5 is heated to weld and fix the resin illumination plate 2 and the transparent acrylic block 5. In addition, in order to weld the resin-made lighting board 2 upper surface and the upper lower surface of the transparent acrylic block 5, the welding part of the resin-made lighting board 2 and the transparent acrylic block 5 is heated previously, and the transparent acrylic block 5 is made of resin. A method of welding by fitting into the light transmitting hole 2a of the illumination plate 2 is also conceivable. Thereafter, the light diffusion portion 5 a is generated on the upper upper surface and the upper side surface of the transparent acrylic block 5. In order to generate the light diffusion portion 5a, for example, there is a method in which a light diffusion coating such as a bead clear coating in which an infinite number of beads are put in a paint is applied to the upper upper surface and the upper side surface of the transparent acrylic block 5. In addition, there is a type in which light diffusion processing such as finish finishing by shot blasting is performed on the upper upper surface and upper side surface of the transparent acrylic block 5. In addition, when producing | generating the light-diffusion part 5a by the finish finish by shot blasting, a clear finish is given beforehand to the upper upper surface and upper side surface of the transparent acrylic block 5, and the transparent acrylic block after light-diffusion part 5a production | generation is carried out It is also possible to place 5 on the resin lighting plate 2 and weld them.

この発明の実施の形態１によれば、かご室天井１から吊り下げられる照明板を樹脂製にして、この樹脂製照明板２と透明アクリルブロック５とを溶着によって固定しているため、従来のように、透明アクリルブロック５をボルトにより締結固定したり、弾性を有する押え金で押え付けて固定したりする必要がなく、照明装置全体の部品点数を大幅に削減できるとともに、組立性も大幅に向上し安価な照明装置を提供することが可能となる。また、樹脂製照明板２と透明アクリルブロック５とは共に樹脂製であるため、軽量で運搬性や据付性に優れる一方、溶着によって一体化しているため、剛性に問題が生じる恐れはない。また、透明アクリルブロック５の上面には光拡散部５ａが備えられているため、かご室内の乗客が透明アクリルブロック５を介してかご室天井１に設置された光源４の形状や樹脂製照明板２より上方の構造を認識することはできず、さらに、透明アクリルブロック５は樹脂製照明板２に溶着固定されているため、その接合面に埃等の異物が入り込む恐れはなく、簡単な構造で意匠性に優れたエレベータかご室を提供することが可能となる。   According to Embodiment 1 of the present invention, since the lighting plate suspended from the car room ceiling 1 is made of resin and the resin lighting plate 2 and the transparent acrylic block 5 are fixed by welding, Thus, it is not necessary to fasten and fix the transparent acrylic block 5 with bolts or to press and fix it with an elastic presser foot, and the number of parts of the entire lighting device can be greatly reduced and the assemblability is also greatly improved. An improved and inexpensive lighting device can be provided. Further, since both the resin lighting plate 2 and the transparent acrylic block 5 are made of resin, they are lightweight and excellent in transportability and installation property, but they are integrated by welding, so that there is no possibility of causing a problem in rigidity. Moreover, since the light diffusion part 5a is provided in the upper surface of the transparent acrylic block 5, the shape of the light source 4 and the resin illumination board which the passenger in the car room installed in the car room ceiling 1 via the transparent acrylic block 5 The structure above 2 is not recognizable. Further, since the transparent acrylic block 5 is welded and fixed to the resin lighting plate 2, there is no possibility that foreign matters such as dust enter the joint surface, and the structure is simple. It is possible to provide an elevator cab with excellent design.

なお、実施の形態１では、光拡散部５ａとして透明アクリルブロック５の上部上面及び上部側面にビーズ入りクリア塗装が塗布されたり、なし地仕上げが施されたりしているが、このビーズ入りクリア塗装やなし地仕上げの代わりに、従来から使用されていた乳白アクリル板と同等の透過率を有する白色又は有色の塗装を塗布することによって実施の形態１と同様の効果を得ることもできる。この場合、透明アクリルブロック５を塗装によって任意の色に着色することができるため、意匠性の良いエレベータのかご室の照明装置を提供することも可能となる。   In the first embodiment, a clear coating with beads is applied to the upper upper surface and upper side surface of the transparent acrylic block 5 as the light diffusing portion 5a, or a clear finish is applied. The effect similar to that of the first embodiment can be obtained by applying a white or colored coating having a transmittance equivalent to that of a conventionally used milky white acrylic plate instead of the finish of the plain background. In this case, since the transparent acrylic block 5 can be colored in any color by painting, it is possible to provide an illuminating device for an elevator cab with a good design.
