2. Description of the Related Art Conventionally, an elevator in which an elevator car apparatus can be vertically moved up and down by a multistage hydraulic jack in which a rod moves up and down in multiple stages, wherein an upper end portion of a top rod of the hydraulic jack is fixed to the elevator car apparatus. It has been known. When the elevator car device is vertically moved up and down by such a multi-stage hydraulic jack, there is a problem that the multi-stage hydraulic jack oscillates and the ride comfort when climbing and descending on the elevator car device is not good.

Therefore, it has been considered that a U-bolt is fitted to an outer surface of a cylinder portion below a multi-stage hydraulic jack and the U-bolt is attached to a support member connected to a building structure by a nut. However, only the steady portion of the lower cylinder portion of the multi-stage hydraulic jack that does not move in the vertical direction is restrained, and the middle rod portion of the multi-stage hydraulic jack is not stabilized. However, there is still a problem that the rod oscillates, and in particular, the rod does not deflect against the lateral deflection of the intermediate rod when the rod moves up and down.

Guide members 30 are respectively provided at four positions on the upper and lower portions in the front-rear direction of the vertical frame portion 16 of the L-shaped platform 28, and the guide members 30 are respectively provided on guide rails 38 erected on both front and rear sides. It is fitted so that it can slide up and down freely. Further, as shown in FIG. 3, the upper end of the uppermost rod 1a of the multi-stage hydraulic jack 2 is fixed to the center of the upper frame 16a provided above the vertical frame 16 of the platform 28, and the multi-stage hydraulic By driving the jack 2, the elevator car device 3 moves up and down. The guide member 30 is formed of a synthetic resin having a high lubricity to improve the slip, and the guide member 30 moves while being guided along the guide rail 38, so that the elevator car device 3 can smoothly move. You will be going up and down. In the figure, reference numeral 44 denotes a door provided at an elevator platform on each floor and capable of opening and closing.
Denotes an openable and closable door provided in the elevator car device 3.

In the elevator as described above, the present invention is characterized in that an intermediate rod, that is, a rod 1b in the second stage from the top is prevented from swaying.

That is, on the second stage rod 1b from the top
The fixing projection 9 is fixed to the side surface of the end by welding.
It protrudes sideways. In addition, horizontal run-out made of angle material
The horizontal piece 8 is fixed to the vertical piece part of the prevention member 4 by welding and

And fix it with a nut 13. A plate-like guide plate 4a is provided at both ends of the lower horizontal portion of the lateral vibration member 4. A guide groove 4b is formed in the guide plate 4a.

On the other hand, on both sides of the vertical frame portion 16 of the platform 28, side frame members 16b are provided.
Is provided with a rail portion 6 for preventing lateral vibration which is long in the vertical direction. The guide grooves 4b of the guide plate 4a provided at both ends of the lateral vibration member 4 are fitted into the lateral vibration preventing rail 6 with play (that is, they face each other via the small gap 7). Thus, the anti-lateral shake member 4 is
A small gap 7 is provided between the rails 6 on both sides to prevent lateral vibration.
And the rod is in the second stage from the top
1b is prevented, but the fixing projection 9 and
Attachment by fixing the horizontal piece 8 and attachment by U bolt 11
The rod 1b at the second stage from the top and the anti-sway member
4 can be fixed double, so that the rod 1
b is more firmly fixed to the anti-vibration member 4, and
Vibration due to vertical movement etc. acts on the rod 1b of the second stage
However, the anti-lateral shake member 4 does not come off. Special
In the present embodiment, the fastener 10 such as a bolt is used.
Is fixed in the vertical direction, and
The fixing with the nut 11 and the nut 13 is
Moving to the second rod 1b from the top and bottom, etc.
Fixing is not easily loosened due to vibrations caused by vibration.

As described above , the lower end is connected to the stand 26 fixed on the concrete slab 25 and attached to the outer surface of the cylinder 18 of the multi-stage hydraulic jack 2 as shown in FIGS.
As shown in FIG. 7 , the U-bolt 40 is attached to a support member 41 connected to a building structure such as a pillar or a beam by a nut 42 so as to prevent the cylinder portion 18 from swaying. Here, since the cylinder portion 18 does not move up and down, even if the cylinder portion 18 is supported by the support member 41 by the simple connecting means using the U bolt 40 as described above, the nut 42 does not move.
Is not loose.

Thus, the elevator car device 3 is moved up and down by driving the multi-stage hydraulic jack 2 as described above. When the multi-stage hydraulic jack 2 is driven, the plurality of rods 1 move upward and extend. As a result, the elevator car device 3 moves up, and the plurality of rods 1 move downward and contract, so that the elevator car device 3 moves down. When the plurality of rods 1 are moved up and down, the upper frame 1 whose upper end is provided above the vertical frame 16 of the platform 28.
The second rod 1b from the top moves vertically in relation to the uppermost rod 1a fixed to 6a. However, both ends of the lateral swing member 4 fixed to the second rod 1b Since the provided guide groove portion 4b is fitted into the lateral vibration preventing rail portion 6 via the small gap 7, the lateral vibration preventing member 4 moves in the vertical direction relatively to the vertical frame portion 16. When the rod 1b of the second stage from the top tries to sway in the middle, the position of the anti-sway member 4 is regulated with respect to the anti-sway rails 6 on both sides via the small gap 7, so that the This prevents lateral deflection of the second-stage rod 1b. In this way, it is possible to prevent the rod 1b of the second stage from the top from moving up and down and prevent the rod 1b from moving up and down with respect to the rails 6 on both sides even when the vertical movement is stopped. Since the position is regulated through the gap 7, lateral deflection of the rod 1b at the second stage from the top is prevented.

By the way, the uppermost rod 1a is
In a state of protruding the maximum from the upper end of the rod 1b of the step, both ends of the anti-vibration member 4 face the guide plate 4a through the small gap 7 slightly above the lower end of the guide plate 4a. In a state where the upper rod 1a is most immersed in the second rod 1b from above, the both ends of the anti-vibration member 4 are slightly lower than the upper end of the guide plate 4a by the small gap 7 to the guide plate 4a. It is set so as to be opposed to each other, so that the anti-lateral shake member 4 always ensures that it can be moved from the top at any stage of ascent and descent.
The horizontal deflection of the rod 1b of the step can be prevented.
