Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevating lighting device, and particularly to a structure that allows a fitting body to be easily fitted into a fitting receiver.

Conventionally, an elevating type lighting device for elevating and lowering relatively heavy lighting equipment has a winding drum 2 disposed inside an elevating base 1 and a fitting receiver 3 on the elevating base 1, as shown in FIG. 1, for example. A pulley 5 is provided on the upper part of the lighting fixture 4, which is configured to be able to rise and fall freely, and a fitting rod 6 is arranged above the pulley 5 in correspondence with the fitting receiver 3. The winding drum 2 supports both upper ends of the wire 7, which is formed by inserting the wire 6 through the winding drum 2.

However, according to the above structure, since the fitting rod 6 is fitted into the fitting receiver 3, precision is required for the spacing between the pair of fitting receivers 3 and the pair of fitting rods 6. Also wire 7
Friction occurs between the moving wheel 5 and the moving wheel 5, causing the lighting fixture 4 to tilt.
There is a drawback that the fitting rod 6 does not fit into the fitting receiver 3 well.

Therefore, an object of the present invention is to provide an elevating type lighting device to which a heavy elevating type lighting device can be easily fitted.

The present invention will be explained below with reference to FIGS. 2 to 5. In the figure, reference numeral 11 denotes a lifting base, 12 a fitting receptacle fixed inside the lifting base 11, and a hollow portion 13 is formed in the center. Reference numeral 14 denotes a fitting body whose upper portion is tapered, and is configured to fit into the hollow portion of the fitting receiver 12. 15 is the fitted body 1
This is a pulley rotatably supported in the hollow part 16 of 4.

Reference numerals 17 and 18 refer to guide plates that are tiltable at both ends of the fitting receiver 12 in the longitudinal direction.
Before being fitted, the two guide plates 17 and 18 form a figure eight shape, and when the fitting body 14 is fitted, the guide plates 17 and 18 are pressed and become vertical. Reference numeral 19 denotes a lock mechanism configured to protrude when the fitting body 14 is fitted into the fitting receiver 12. A fixing pin 20 protrudes from the side wall of the fitting receiver 12 and the fitting body 14, and is inserted through the locking mechanism. It is configured to lock onto the receiver 12. 21 is pulley 15
23 is an upper contact provided on the lower surface of the fitting receiver 12, and 24 is a lower contact provided on the side wall of the fitting body 14 in correspondence with the upper contact 23. . 25 is the elevating body 2
The lighting fixture supported at the bottom of 6 is a relatively heavy one or a plurality of lighting fixtures.

Next, the operation of the elevating lighting device having the above structure during elevating and lowering will be explained.

When the winding drum 22 is rotated and the wire 21 is wound, the fitting body 14 is guided by the guide plates 17 and 18 and fitted into the hollow part 13 of the fitting receiver 12, and the locking mechanism 19 is then fixed. A pin 20 protrudes from the side wall of the fitting receiver 12 and the fitting body 14 and
is locked into the fitting receiver 12.

When the fitting body 14 is fitted into the fitting receiver 12, the guide plates 17 and 18 guide the fitting body 14.
Even if the lighting fixture 25 is inclined to some extent, it can be easily fitted.

Further, in order to lower the lighting fixture 25, the locking mechanism 19 is activated, the fixing pin is pulled out from the fitting receiver 12 and the fitting body 14, and the winding drum 22 is reversely rotated, thereby easily lowering the lighting fixture 25. I can do it.

As described above, the present invention includes a fitting receiver provided inside the lifting base, a tiltable guide plate provided at both ends of the space in the longitudinal direction of the fitting receiver, and a pulley mounted along the guide plate. Since the structure is such that the fitting body with the locking mechanism is inserted into the fitting body, and the fixing pin of the locking mechanism is inserted from the side surface of the fitting receiver and the fitting body, the fitting body will not move even if the lighting fixture is tilted to some extent as described above. It can be easily fitted into and supported by the fitting receiver, and has great utility as an elevating lighting device for lifting and lowering relatively heavy lighting equipment.
