Description

[Detailed description of the invention] [Technical field of the invention] This invention provides lighting for an elevator car in which an outer lighting frame member and an intermediate lighting frame member together form a lattice-shaped light ceiling on the ceiling side of the elevator car. Concerning improvements to frame devices.

[Technical background of the invention and its problems]

Optical ceilings are often used in high-end elevators and the like. This type of light ceiling is generally constructed by fixing a lattice-shaped light frame device consisting of an outer light frame member and an intermediate light frame member to a light case equipped with a light source pre-installed on the ceiling of the car room. This structure is adopted, and a light ceiling is constructed by using this lighting frame device as a support and providing a transparent body such as a louver inside.

Incidentally, the lighting frame device usually employs an arrangement in which an outer lighting frame member forms a rectangular outer frame that fits the car compartment, and a plurality of intermediate lighting members are incorporated in a lattice shape within this outer frame. . As this embedding technique, the one shown in FIGS. 1a and 1b has conventionally been used.

That is, a plurality of intermediate lighting frame members a... are assembled in a lattice shape by screwing using L-shaped connecting fittings b..., and a plurality of external lighting frame members e... are assembled on all sides of this lattice-like structure. In the same way as before, use L-shaped connecting fittings d... to screw them together, and finally fix the external lighting frame member c... with screws using L-shaped connecting fittings e... to attach the outer frame f. The constituent elements have been adopted. In addition, g is a fixing screw, h is a spring washer,
i indicates nut.

However, according to the technique of constructing a lighting frame device using such L-shaped connecting fittings b, d, and e, intermediate lighting frame members a... are connected to external lighting frame members c.
Because a part of the fixing screw g protrudes to the outside at the point where it is connected to A mounting hole l... is required. For this reason, the manufacturing process of the lighting frame device has the drawback that two steps are required for setup, which inevitably reduces work efficiency. Moreover, the intermediate lighting frame member a..., the external lighting frame member c...
In addition, because the assembly is performed through the tightening holes drilled in each of the connecting fittings b, d, and e, a step is likely to occur at the joint where the transparent body n such as a louver is placed.
There is a problem that gaps are likely to occur. Moreover, this correction requires loosening the fixing screw g that has been tightened, adjusting it, and then tightening it again, which is a problem that requires a lot of time. In addition, when tightening, a large number of nuts are used, which are said to be difficult to work with, so the workability is not very good.
Moreover, the use of a large number of fixing screws g and nuts i has the disadvantage of increasing costs.

Therefore, in view of this point, in Japanese Patent Application Laid-Open No. 51-55548, a structure is adopted in which the outer lighting frame member and the intermediate lighting frame member are provided with a substantially inverted T-shaped groove. A technique has been proposed in which a lighting frame member and an intermediate lighting frame member are assembled while ensuring good seams. That is, as shown in FIGS. 2a and 2b, for example, the intermediate illumination frame member o
A bolt r is movably inserted into the groove q of the bolt r, and a fitting s corresponding to the shape of each intersection is passed through the bolt r. Then, a nut t is inserted into the threaded portion of each bolt r. Adjacent members are connected by fitting and fastening.

However, according to the technology using this bolt r..., it is certainly possible to secure a good joint by fastening from a position close to the joint, but on the other hand, a large number of nuts t... are required for fastening. This does not improve workability, and furthermore, since the ends of the bolts r protrude outward together with the nuts t, there is a problem that there is a risk of getting caught during assembly work. Moreover, cost issues remain due to the large number of uses of nuts.

[Purpose of invention]

This invention was devised in view of the above circumstances, and its purpose is to provide a lighting frame device for an elevator cab that can ensure efficient and safe work and good joints at a low cost. be.

[Summary of the idea]

In this invention, connecting pieces are movably inserted into the grooves of the outer lighting frame member and the intermediate lighting frame member, each having a substantially inverted T-shaped groove, and a fixing screw is screwed into the connecting piece through an opening in the groove to connect the outer lighting frame member and the intermediate lighting frame member. By fastening the pieces, the adjacent members on the intersection are connected together, simplifying the manufacturing process of the lighting frame device, reducing the number of nuts, and eliminating the protrusion of the bolt tips. The aim is to achieve efficient and safe work and to ensure good joints by attaching joints and creating connections without creating steps at intersections.

A cross-shaped connecting piece 25 composed of a connecting plate 24 having a hole therein is movably inserted over the adjacent grooves 19 and 21, and the sides of this connecting piece 25 are inserted into each groove 19, 20. They are fastened by fixing screws 26 screwed through the openings, and the adjacent intermediate illumination frame members 18, 20...20 are connected together. Thus, the connecting pieces 25 spanning the intersections 22 form a lattice-shaped intermediate frame 10 with a flush upper surface. In addition, 23a is a screw hole for tightening provided on both sides of the connecting plate 23, and 23b is a screw hole for connecting plate 23 and connecting plate 24.
This is a screw hole for fixing both.

The intersecting portion 27 of the intermediate frame 10 and the outer frame 9 intersecting in a T-shape is connected by using the connecting plate 23 shown in FIG. Connecting plate 2 with perforated
