Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to an elevating type lighting fixture.

[Background technology]

BACKGROUND ART Conventionally, a type of elevating type lighting equipment is known that is used in facilities such as gymnasiums with an exposed elevating device.

On the other hand, even in modern houses, elevating type lighting fixtures are being used in high ceilings such as open atriums, and elevating devices are installed recessed in the ceiling from the viewpoint of aesthetics of the house. In addition, there is a recent trend in open ceilings with sloped ceilings, and there is a need to accommodate this trend.

[Purpose of invention]

Therefore, the present invention has been made in view of the above-mentioned background, and an object of the present invention is to provide an elevating type lighting fixture in which an elevating device is installed in a ceiling ceiling in correspondence with a sloped ceiling.

[Disclosure of invention]

The elevating type lighting equipment according to the present invention has an elevating device body mounted embedded in the ceiling ceiling of a sloped ceiling, and a flange of the lighting device body attached to an elevating part that is suspended from the elevating device body and inserted through an opening provided in the ceiling. An adjustment tool that covers the opening and is brought into close contact with the ceiling, and that corresponds to the depth of the ceiling by selecting the vertical position of a mounting hole that is interposed between the elevating part and the lighting equipment body and is connected to the elevating part. At least one of the mounting holes is formed to form an arc in the vertical plane, and the lighting equipment body is installed at an angle so that it can swing relative to the lifting section, and the flange of the lighting equipment body is brought into close contact with the ceiling. Even if the motor capacity required for this is reduced, it is possible to reliably place the motor close to the ceiling.

〔Example〕

1 to 6 show embodiments of the present invention, which will be explained below based on the figures. The lifting device main body 1 is hung from the building structure with bolts and installed while maintaining the horizontal position, and a motor 2 is installed inside.
It houses electrically conductive parts for lighting equipment, as well as elevating mechanisms such as 0 and wire winding drum 22. An elevating section 2 suspended by a wire 24 is provided on the central lower surface of the elevating device main body 1, and electrical conduction between the elevating section 2 and the elevating device main body 1 is performed by opening/closing contacts. In the lifted state, the lifting device body 1
A support stand 4 is attached to the elevating part 2 which maintains a constant positional relationship with the support stand 4 so as to be movable up and down by the expansion and contraction of a spring 3.
is screwed on. The angle 5 has female threads 12, 12 screwed into vertical pieces 11, 11 at both ends thereof, and an adjuster 6 having a substantially U-shaped cross section has female threads 12, 12.
It is swingably suspended and attached by fixing screws 7, 7 screwed together. The adjuster 6 has a plurality of screw insertion holes 14, 14, which are mounting holes in the vertical direction of the U-shaped double protruding pieces 13, 13, and which one of the plurality of screw insertion holes 14, 14, etc. It is becoming more and more important to choose one. On the bottom of the adjustment tool 6,
For example, a lighting fixture main body 8 of a multi-light lighting fixture with lamps suspended from a plurality of arms is attached, and a flange 9 is attached to cover the center of an opening for mounting the lifting device main body 1 provided in the ceiling. . In the opening provided in the ceiling for attaching the lifting device main body 1, there is a blind plate 10 in the shape of a donut plate, which has an opening in the center for inserting the lifting device 2.
It is attached to the ceiling by covering the outer periphery of the mounting opening, and the flange 9 covers the central opening of the blind plate 10.

When dealing with differences in ceiling height, this elevating type lighting equipment selects one of the multiple screw insertion holes 14, 14... of the adjustment tool 6 according to the height of the ceiling height, and then Insert the fixing screws 7, 7 into the insertion holes 14, 14, and tighten the female thread 1 of the angle 5.
2 and 12, and the lifting device main body 8 and flange 9 are attached to the bottom surface, the adjustment tool 6 is attached to the angle to make large adjustments to accommodate various ceiling heights. For areas that cannot be reached, bend the spring 3 and attach the support base 4.
Fine adjustments are made by moving up and down. Furthermore, if the ceiling is deep and cannot be adjusted by selecting only the screw insertion holes 14 of the adjustment tool 6,
The angle 5 may be reversed so that the vertical piece 11 of the angle 5 faces downward. Screw insertion hole 1 of adjustment tool 6
4, each of the vertical pieces 11, 11 corresponding to each other is formed in an arc shape, so that when the ceiling is sloping, the lighting fixture main body 8 and flange 9 can be hung at an angle with respect to the lifting part. The angle adjustment holes 15, 15 are provided so that the angle can be adjusted. The angle adjustment hole 15 may have a simple arc shape, but in this embodiment, a plurality of approximately semicircular notches are provided at predetermined positions on the upper edge of the hole, and the fixing screw 7 is locked therein. The locking portions 16, 16, . . . When adjusting the inclination of the flange 9 to match the inclination of the ceiling using the angle adjustment hole 15, loosen the stepped fixing screw 7 to expose the stepped part outside the angle adjustment hole 15, and use the threaded part to adjust each engagement. By moving between the stop portions 16 and screwing the stepped portion into the lock portion 16 closest to the required inclination angle, the lock portion 16 will not come off from the fixing screw 7. The area around the opening in the center of the blindfold plate 10 is a stepped recess, and the wall surface of this recess is angled so that it faces vertically downward when it is installed on a ceiling with the maximum slope within a predetermined range, so that it does not interfere with the insertion of the flange 9. The flange 9 stays in place without slipping.

In this case, since the adjuster 6 is swingably suspended from the angle 5, when the lighting fixture is raised, the flange 9 inclined by the arc-shaped screw insertion hole is approximately connected to the blind plate 10. When it is pulled up further after making contact, it rotates and comes into close contact with the blindfold plate 10.

The lifting device is constructed as shown in FIGS. 5 and 6, and a motor 20 rotates a wire winding drum 22 via a decelerator 21, with one end fixed to the wire winding drum 22 and the other end fixed to the wire winding drum 22. A wire 24 fixed to the elevating section 2 is wound up and unwound, and a pulley 23 changes the direction of the wire 24. 25 is a lock for locking the lifting portion 2. The elevating device main body 1 has an approximately rectangular parallelepiped outer shape, and by aligning its shorter side with the inclination direction of the ceiling, the required height of the elevating device can be reduced. 17 is a gauge for adjusting the embedding depth.

[Effect of idea]

In this way, according to the present invention, the mounting hole provided in the adjustment tool is formed in an arc shape, and the lighting fixture is installed close to the slope of the ceiling from the beginning so that it can swing freely. This has practical effects such as being able to reduce the capacity of the motor of the lifting device compared to the case where the lighting fixture is pulled up close to the ceiling against the moment.
