DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. That is, the lifting device has a first lifting device 1 and a second lifting device 2. The first lift 1 and the second lift 2 are provided with
And the wires 5 and 17 that suspend the lifting units 3 and 16
(Not shown) which incorporates the drums 6 and 6 'for winding or feeding the drum and drives the drums 6 and 6'
Are provided. The mounting portion 8 of the first elevator 1 is attached to the lifting portion 16 of the second elevator 2.

In the embodiment, as shown in FIG. 2, the first elevator 1 has a pair of pulleys 12 and 13, and the lower end of the first elevator 3 has a lighting fixture. 9 is attached. The mounting portion 8 includes a main body 10 containing a drum 6 and a motor (not shown) and a connecting portion 11. One end of the wire 5 is fixed to the fixing portion 14 of the main body 10, the intermediate portion thereof is wound around the pulleys 12 and 13 and the pulley 15 provided on the main body 10, and the other end is wound around the drum 6. The second elevator 2 also has the same configuration as the first elevator 1, but differs in that
The second elevator 2 has contacts 19 and 20 that come into contact with each other at a position where the elevator 16 is lifted, on the opposing surfaces of the elevator 16 and the mounting part 18, and the mounting part of the first elevator 1 through the contacts 19 and 20. 8 are supplied with power. The mounting portion 18 of the second elevator 2 is mounted on the ceiling 23.

The operation will be described. Second elevator 2
Are in the ascending position and the contacts 19 and 20 are in contact with each other, and the motor of the first elevator 1 can be supplied with power. Therefore, when the motor is rotated in the downward direction, the drum is extended and the wire 5 is rotated. The first elevating unit 3 descends and the lighting fixture 9 descends. The lowered position of the first lifting unit 3 is detected by the end detection switch, the motor stops, and the lighting fixture 9 stops. Next, power is supplied to the motor of the second elevator 2, and when the motor is rotated and the drum is extended and rotated, the wire 17 is extended and the second elevator 16 is moved.
Descends, whereby the first elevator 1 descends and descends until the end detection switch of the second elevator 16 operates. At this time, the contacts 19 and 20 are separated, and the power supply to the first elevator 1 is stopped. Thus, the first elevator 1 and the second elevator
The elevators 2 move down the elevation height twice as long as the respective elevation distances, and even if the lighting fixtures are mounted on the ceiling, the elevation height of which is about twice as high as normal Therefore, it is possible to descend to the floor.

Next, when the lighting apparatus 9 is lifted, first, the motor of the second elevator 2 is driven to wind and rotate the drum. As a result, the elevating unit 16 moves up and down to raise and lower the first elevator 1, and the contacts 19 and 20 come into contact at the highest position. Next, power is supplied to the motor through the contacts 19 and 20 to the first elevator 1 to wind and rotate the drum, and the elevator 3 is raised to raise the lighting fixture 9.

According to the first embodiment, the combination of the first elevator 1 and the second elevator 2 enables the ascending and descending of a long distance. In addition, the configuration using a technically established elevator is used in combination, so that the quality can be ensured, and since the lifting distance of each elevator is not particularly high, no special evaluation equipment is required. Also, since the first elevator 1 is supplied with power from the second elevator 2 via the contacts 19 and 20, the operation of the lower first elevator 1 is prioritized at the time of the lowering operation of the lighting fixture, and at the time of the upward operation. The operation of the upper second elevator 2 is prioritized.

A second embodiment of the present invention will be described with reference to FIG. That is, in this elevating device, the second elevator 2 in the first embodiment is composed of a plurality of elevators 2a to 2c connected in series to each other, and the connection relationship is the mounting part of the lower elevator. 18a are sequentially attached to the lift 16a of the upper lift. However, the lifting section 16a of the lowermost elevator 2a is connected to the mounting section 8 of the first elevator 1, and the mounting section 18a of the uppermost elevator 2c is mounted on the ceiling 23.

According to this embodiment, since the number of elevators is two or more, it is possible to further raise and lower the instrument.
Others are the same as in the first embodiment. A third embodiment of the present invention will be described with reference to FIG. That is, this lifting device has the power supply means 24 built in the mounting portion 8 of the first lifting device 1 in the first embodiment. In the embodiment, for example, a battery is used as a motor power supply.

According to this embodiment, the first elevator 1
And the motor of the second elevator 2 can be operated at the same time, so that the elevation speed can be increased. Further, compared with the first embodiment, no contact is required. Others are the same as in the first embodiment. A fourth embodiment of the present invention will be described with reference to FIG. That is, in this elevating device, the lighting fixture 9 is attached to the attachment portion 8 of the first elevator 1, the attachment portion 18 of the second elevator 2 is attached to the ceiling 23, and the first elevator 1 and the second The elevators 3 and 16 of the elevator 2 are connected to each other. Others are the same as the third embodiment.
