TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for mounting an elevator car handrail having a handrail bar provided inside a side plate of a car and a support bracket for supporting the handrail bar.
[0002]
[Prior art]
In recent years, there has been an increasing demand for elevators to have handrails in the elevators to make it easier for all people, including the elderly and the physically handicapped, to use the elevators from the viewpoint of barrier-free and universal design. .
[0003]
However, when the above-mentioned handrail is installed in the car, two workers need to perform screwing work of the handrail from the inside and outside of the car, so that not only the workability at that time is poor. However, since this work is generally performed in a gap between the narrow car and the hoistway, there is a risk that an operator may fall down on the hoistway or be caught between the rider and the hoistway.
[0004]
Therefore, as a means for solving the conventional problems as described above, a seat plate provided with a welding nut or the like is arranged in advance on the outside of the side plate of the car, and a fastening screw from the inside of the car to the welding nut of the seat plate. There has been proposed a technique in which a support bracket is fixed to a side plate by screwing (for example, see Patent Document 1).
[0005]
FIG. 5 is a plan view showing a car of this type of elevator, and FIG. 6 is a longitudinal sectional view taken along line AA of FIG.
[0006]
The car 1 shown in FIG. 5 has a side plate 2 erected on the side, and three columnar handrails 17 are attached to the side plate 2 via a plurality of supports 11, respectively. Each support 11 is fixed inside the side plate 2 and is horizontally separated from each other.
[0007]
As shown in FIG. 6, one end (right end in FIG. 6) of the support 11 is fixed to a welding nut 13 of a seat plate 12 provided on the back surface of the side plate 2 by fastening a fastening screw 15. . The support 11 has a stepped hole 14 that is recessed from the other end (the left end in FIG. 6) and opens toward the inside of the car 1, the fastening screw 15 is a pan screw, and the head is stepped. The spring washer 16 is mounted and buried in the hole 14, and the tip is screwed into the welding nut 13. A recess 18 for receiving the handrail 17 is formed at the other end of the support 11, and the opening end of the stepped hole 14 is in contact with the recess 18 and a spring washer is attached to the other end of the support 11 from below. A mounting screw 19 made of a P truss screw is inserted through 20, and the mounting screw 19 is screwed into the handrail bar 17.
[0008]
In the method of mounting the handrail in the car configured as described above, the seat plate 12 provided with the welding nuts 13 is arranged in advance on the outside of the side plate 2 of the car 1 by welding or bonding and the like. From the inside, the support tool 11 is fastened to the side plate 2 with the fastening screw 15, and the handrail bar 17 is attached to the concave portion 18 of the support tool 11 to cover the opening of the stepped hole 14, and the handrail bar 17 is attached to the mounting screw. Fix at 19. Thereby, the handrail can be attached by work from inside the car 1.

JP-A-7-97163 (paragraph numbers 0010, 0011, 0013, 0015, 0016, FIGS. 1, 2 and 3)
[0010]
[Problems to be solved by the invention]
By the way, in the above-mentioned conventional technology, when the existing elevator is modified to provide the handrail on the car 1, the seat plate 12 provided with the welding nut 13 may not be provided beforehand on the outside of the side plate 2. When the seat plate 12 is disposed outside the side plate 2 by welding or bonding, there is a problem that a work involving danger in a gap between the generally narrow car 1 and the hoistway is required.
[0011]
The present invention has been made in view of the actual situation in the prior art as described above, and an object of the present invention is to provide an elevator car handrail that can be easily attached to an existing elevator only by working in the car. It is to provide an attachment method.
[0012]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a handrail bar provided inside a side plate of a car, a support bracket fixed inside the side plate and supporting the handrail bar, and disposed behind the side plate. In the method of mounting a handrail in an elevator car having a mounting seat to be mounted and a fastener for fastening the support bracket to the mounting seat, the mounting seat includes a first screw hole into which the fastener is screwed. A second screw hole provided in the vicinity of the first screw hole, the mounting seat can be inserted into the side plate at a mounting position of the support bracket, and the second screw hole of the second screw hole is formed. After drilling an insertion hole of a predetermined size according to the position dimensions, in a state where the mounting seat is hung by a hanging body from inside the car, the mounting seat is inserted into the insertion hole and Place it on the back side of the side plate, A mounting plate having a first through hole facing the first screw hole and larger than the screw hole, and a second through hole facing the second screw hole and larger than the screw hole. Is provided inside the side plate, a long bolt is inserted into the first through hole of the mounting plate, and the long bolt is inserted from the inside of the car into the insertion hole of the side plate, and The screw body is screwed into the first screw hole, and then the second through hole of the mounting plate is aligned with the second screw hole of the mounting seat, so that a screw body is inserted from the inside of the car into the second hole of the mounting plate. The mounting plate and the mounting seat are screwed and fixed by being inserted into the through hole of the side plate and the insertion hole of the side plate and screwed into the second screw hole of the mounting seat. Remove from the first screw hole of the mounting seat After extracting from the entrance hole and the first through hole of the mounting plate, the support bracket is disposed at the mounting position of the side plate from inside the car, and the fastener is connected to the first through hole of the mounting plate. And fixing the support bracket to the side plate by inserting it into the insertion hole of the side plate and screwing it into the first screw hole of the mounting seat. Then, the handrail is attached to the mounted support bracket. The rod was fixed.
[0013]
As described above, according to the mounting method of the present invention, in a state where the mounting seat is hung from the inside of the car, the mounting seat is inserted into the insertion hole and arranged on the back side of the side plate, and the long bolt is inserted from the inside of the car into the side plate. Then, the mounting seat is held by the long bolts, and the mounting plate is fixed to the mounting seat by inserting into the insertion hole and screwing into the first screw hole of the mounting seat. With this, even if the existing elevator does not have the mounting seat on the outside of the side plate in advance, the mounting seat is provided from the inside of the car and the rail in the car can be easily mounted only by working inside the car. can do.
