The fastening plate 6 has a mounting hole 7 formed of a daruma hole corresponding to the mounting hole 4 of the flange portions 3b, 3b of the component plates 3a, 3a.
[0017]
The Dharma hole of the attachment hole 4 formed in the flange portion 3b and the Dharma hole of the attachment hole 7 formed in the fastening plate 6 are arranged in opposite directions along the moving direction of the fastening plate 6. In the present embodiment, the darma holes of the mounting holes 4 formed in the flange portion 3b are arranged so that the large-diameter portion is on the upper side and the small-diameter portion is on the lower side. The holes are arranged such that the small diameter part is on the top and the large diameter part is on the bottom.
[0018]
As shown in detail in FIG. 4, the outer surface of the fastening plate 6 is formed with a tapered surface that is inclined along the moving direction corresponding to the position of each of the mounting holes 7. A pressing portion 8 that generates a pressing action on a holder described below is configured. In the present embodiment, the pressing portion 8 is formed of a tapered surface whose thickness gradually increases from bottom to top.
[0019]
A bolt mounting hole 9 is formed above the mounting hole 7 of the fastening plate 6 at a position corresponding to the bolt mounting hole 5 of the flange portion 3b.
[0020]
The holder 10 is inserted into the mounting hole 4 formed in the flange portion 3b and the mounting hole 7 formed in the fastening plate 6. The holder 10 has a shaft portion 10a having a smaller diameter than the small-diameter portion of the daruma hole. At both ends of the shaft portion 10a, locking portions 10b, 10b are formed. The holder 10 is maintained in an inserted state across the flange portion 3b and the fastening plate 6 through the large-diameter portions of the mounting holes 4 and 7, and the fastening plate 6 is driven downward to be moved, so that the shaft portion is moved. 10a fits into the small holes of the mounting holes 4 and 7 to prevent falling off, while the locking portions 10b and 10b are gradually pressed outward by the tapered surface of the pressing portion 8 of the fastening plate 6, and The locking portions 10b, 10b fasten the flange portions 3b, 3b by the reaction force.
[0021]
The car according to the present embodiment is assembled as follows. That is, a pair of flange portions 3b, 3b of adjacent component plates 3a, 3a are opposed to each other, and a fastening plate 6 is disposed outside the flange portion 3b of at least one component plate 3a. After the holder 10 is inserted through the mounting holes 4 of the flange portions 3b, 3b and the mounting holes 7 of the fastening plate 6, the fastening plate 6 is driven downward and moved. Then, the elastic portion 8 of the fastening plate 6 presses the locking portion 10b of the fastener 10 outward, and the reaction force causes the pair of flange portions 3b, 3b to be fastened via the fastening plate 6. Finally, the bolts 11 are inserted into the bolt mounting holes 5 and 9 to prevent the fastening plate 6 from coming off, and the bolts 11 are tightened and fixed by the nuts 12, so that the pair of flange portions 3b and 3b can be fixed.
[0022]
As described above, according to the present embodiment, after the fastening plate 6 and the holder 10 are attached to the adjacent component plates 3b, 3b, the fastening plate 6 is moved to collectively form the pair of flange portions. 3b, 3b can be fastened. In addition, the same fastening force can be applied to all the fastening points of the pair of flange portions 3b, 3b. Therefore, it is possible to easily perform the fastening with a stable fastening force without variation, shorten the assembling time, and prevent the occurrence of troubles such as forgetting to fasten due to an increase in the number of fastening locations. .
[0023]
FIG. 5 is a perspective view showing a fastening plate used for an elevator car according to a second embodiment of the present invention. In the present embodiment, the difference from the first embodiment is that the mounting holes 14 of the fastening plate 13 are wider than the locking portions 10b of the holder 10 so that the holder 10 does not come off in place of the darma holes. It is formed by a narrow slot. According to the present embodiment, by attaching the necessary holders 10 to the fastening plate 13 in advance without falling off, when assembling the car at the elevator installation site, a large number of the holders 10 are attached to the fastening plate 13. The work of inserting can be omitted.
[0024]
FIGS. 6A and 6B are a front view and a side view showing a fastening plate used for an elevator car according to a third embodiment of the present invention. The present embodiment is different from the first embodiment in that an elastic material such as spring steel is used for the material of the fastening plate 15, which is bent in a saw-tooth shape by press working or the like, so that the individual mounting holes 7 are formed. The pressing portion 16 is configured correspondingly. According to the present embodiment, since the pressing force of the pressing portion 16 acts elastically, the fastening plate 15 itself can have a function of preventing loosening. Also, by providing a barb 17 for fixing the holder by pressing or the like near the mounting hole 7 of the fastening plate 15, when the fastening plate 15 moves and moves to the small hole of the mounting hole 7, The holder is hooked on the barb 17 and can function as a stopper for the holder.
[0025]
