Instead, the doorway component can be installed at a desired mounting position, so that downsizing and weight reduction can be realized. Further, since the above-mentioned holding body 12 is also used for holding the hall sill 9 and the door pocket 10, reduction in size and weight can be realized from this point as well.

Further, the hall sill 9 or the door pocket 1
0, the weight corresponding to the gripping body 12, for example, 60
Although it weighs about kg, it is urged upward by the coil spring 14 so that the gripper 12 can be manually moved up and down smoothly, and moreover, the front side of the car frame 1. That is, since the up-and-down movement of the gripping body 12 can be operated on the side facing the landing 11, the installation work of the entrance / exit components such as the landing sill 9 and the door pocket 10 can be easily performed.

In the above embodiment, the upper end of the column 8 is set at a height substantially equal to that of the handrail 3 at the intermediate position in the height direction of the car frame 1, and the upper end of the column 8 is located at the upper base. While being supported by the above handrail 3 via 7,
Since the lower end of the column 8 is supported by the car sill 2 of the car frame 1 via the lower base 6, the structure of the column 8 can be compact and simple.

Further, in the above embodiment, when the column 8 erected on the car frame 1 is inclined to exceed the allowable range of the verticality, the verticality of the column 8 is adjusted by the verticality adjusting means 13. Since the entrance and exit components can be reliably positioned by eliminating the inclination, the installation work of the entrance and exit components can be easily performed from this point as well.

[0034]

As described above, according to the first aspect of the present invention, the size and weight can be reduced as compared with the case where the portal frame is provided, and the entrance and exit can be easily achieved. Since the installation work of the parts can be performed, there is an effect that the work efficiency at the time of installing the elevator entrance and exit parts can be improved. In addition, a winch, a wire rope, a pulley, and the like for driving the gripper are not required, and a single type of gripper can be used for holding the landing sill and the door pocket, so that the number of parts can be reduced and the structure can be reduced. There is also an effect that a simple installation device can be obtained, and thus the manufacturing cost can be reduced.

Further, according to the invention of claim 2 of the present invention, the structure of the pillars erected on the car frame can be made compact and simple, and therefore, a smaller and lighter elevator entrance / exit component can be provided. There is an effect that an installation device can be obtained.

According to the third aspect of the present invention, when the column standing on the car frame is inclined to exceed the allowable range of verticality, the verticality of the column is changed to the verticality. The inclination can be eliminated by adjustment by the adjusting means, and therefore, there is an effect that the working efficiency at the time of installing the elevator entrance / exit components can be further improved.
