Description

[Detailed description of the invention] This invention relates to an improvement of an elevator cab.

First, a conventional elevator cab will be explained with reference to FIGS. 1 to 4.

In the figure, 1 is the elevator hoistway wall, 2 is the car room,
3 is a counterweight, and the car room 2 is composed of a ceiling plate 4, a side plate 5, a pillar 6, a floor 7, and the like. Reference numeral 8 is a hole drilled in the edge of the side plate 5, 9 is a bolt inserted through the hole, and 10 is a nut screwed into the bolt 9.

That is, the side plates 5 are sequentially placed on the floor 7 and fastened with bolts (not shown). Next, in order to fasten the side plates 5 to each other, bolts 9 are inserted into the holes 8 in the side plates 5, and the fastening is completed with nuts 10. The pillars 6 and the ceiling plate 4 are fastened, and the car compartment 2 is assembled in a box shape. .

However, the edge of the side plate 5 is U-shaped, and although the bolt 9 is inserted into this part and fastened with the nut 10, the gap between it and the hoistway wall 11 is narrow, so the work must be carried out with a tightening tool in both hands. It was difficult to do so.

This invention aims to eliminate this drawback and provide an elevator cab in which the side plates can be easily connected to each other.

An embodiment of this invention will be described below with reference to FIGS. 5 and 6.

In the figure, the same reference numerals as those in Figures 1 to 4 indicate corresponding parts, 8 is a square hole provided at the edge of the side plate 5, and 9 is a square root bolt with a square root 9a corresponding to the square hole 8. The edges of the side plates 5 are inserted into square holes 8 between each other. Reference numeral 10 denotes a nut having a flange portion on its end surface, and has a length greater than the length of the folded portion of the U-shaped edge of the side plate 5 (see FIG. 5).

That is, when screwing the nut 10 into the square root bolt 9, the square root bolt 9 is tightened by the square root 9a and the square hole 8.
The nut 10 is long as described above, and protrudes from the folded portion of the U-shaped edge of the side plate 5. Therefore, the tightening tool can be operated visually and the side walls 5 can be fastened together by rotating the nut 10 with one hand, even in a narrow space between the side wall 5 and the hoistway wall 11. The cage 2 can be easily assembled.

As described above, this invention forms a square hole in the bottom portion of the U-shaped bent portion at the edge of the side plate, and inserts a square root bolt that fits into this square hole into the U-shaped bent portion. Because a nut longer than the length of the folded part of the curved part was screwed into the bolt and the edges of adjacent side plates were fastened together, the edges of the side plates were bent into a U-shape and difficult to see. The objective of the present invention is to realize an elevator cab that can be assembled easily in a short time and can be assembled with one hand in a narrow hoistway even though the elevator car is in a narrow hoistway.
