Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embedded lighting fixture mounted on a ceiling or the like, and more specifically, it does not require bolts to be mounted and is restricted by the material and shape of the side wall of the fixture when mounting. There is no lighting equipment.

[0002]

2. Description of the Related Art Conventionally, when a ceiling-embedded luminaire is attached to a ceiling, for example, the luminaire main body is inserted into an embedding hole provided in the ceiling and is hung from above the ceiling. Insert two bolts into the two through holes provided on the upper surface of the instrument body and fix the instrument body with nuts, or
Alternatively, when the weight of the luminaire is relatively light, the mounting bracket is slidably moved along a pair of slits provided in the side wall of the luminaire body in a vertical direction, and this is brought into contact with the back surface of the ceiling, The fixture body was fixed.

FIG. 21 shows, for example, Japanese Utility Model Laid-Open No. 63-15710.
FIG. 3 is a vertical cross-sectional view showing an example of the lighting fixture disclosed in Japanese Patent Publication No. 7-37, showing a method of fixing the fixture main body to the ceiling using bolts. Reference numeral 1 is a fixture main body of a lighting fixture, 2 is a side edge formed in a space provided in a spine-out portion, 3 is a reinforcing plate which is attached to the side edge 2 so as to be slidable in its longitudinal direction, 4 is a reinforcing plate 3 The fixture body 1 is inserted into the mounting hole provided in the ceiling 5
A bolt for suspension which is fixed to, and 6 is a nut screwed with the bolt 4.

Next, the operation of the luminaire constructed as above will be described. First, the bolt 4 is inserted into a mounting hole provided in the reinforcing plate 3 from above, and is fixed with a nut 6 from below. When the bolt 4 is not in the proper position, the reinforcing plate 3 is slid in the longitudinal direction to adjust the position of the bolt 4. Thus, since the reinforcing plate 3 is movably attached to the fixture body 1, it is not necessary to adjust the position of the bolt 4 each time the lighting fixture is attached to the ceiling 5, and the fixture body 1 is deformed by an external force. There is nothing to do.

FIG. 22 shows, for example, Japanese Patent Publication No. 03-61283.
It is a perspective view which shows an example of the principal part of the lighting fixture disclosed by the publication, and shows the method of fixing a fixture main body to a ceiling using the fixture side wall of a fixture main body. Reference numeral 1a is an instrument body, and 7 is a T-shaped vertical slit formed on the side wall of the instrument body 1a.
Further, 8 is a fixture curved in a substantially U shape, 9 is a fixture 8
Guide pieces provided at the open side ends of the opposite side pieces of
Reference numeral 10 denotes a pair of locking springs that are pressed against the outer surface of the side wall of the instrument body 1a. The locking springs 10 are provided at the upper edges of both side pieces and have tapered ends.

Next, the operation of the luminaire constructed as described above will be described. In order to fix the instrument body 1a to the ceiling, first, the fixture 8 is inserted into the vertical slit 7 provided on the side wall of the instrument body 1a from the inside and pushed down along the vertical slit 7 until it abuts against the ceiling back surface. By doing so, the locking spring 10 presses against the outer surface of the side wall of the instrument body 1a, and the instrument body 1a
a is fixed. Therefore, the fixture 8 is only one part, and the lighting fixture can be easily attached to the ceiling.

[0007]

As is apparent from the above description, the illuminating device according to the present invention has an instrument main body and slides (claims 2, 4 and 7) or rotation (claims) on the instrument main body. The movable main body according to claim 3, claim 5, and claim 7) and a slide metal fitting that slides in the left and right hollow portions of the movable main body are provided, and the slide metal fitting is projected from the movable main body to lock the instrument main body on the ceiling back surface. Or a device main body and a slide fitting that slides directly on the device main body (claim 6),
The slide metal fitting is slid to lock the instrument body to the back of the ceiling. Therefore, the bolt is not required to suspend the instrument body, and the work for attaching the bolt to the ceiling is not required.

Further, when mounting the instrument main body on the back surface of the ceiling, the sliding metal fitting in the movable main body is slid and fixed by the handle (claims 2 to 6), or when the movable main body has a corrugated locking portion. Can be fixed by sliding the slide metal fitting and stopping it at a predetermined position (Claim 7).
Installation on the back of the ceiling becomes easy. Further, when the movable body itself can slide or rotate (claims 2 to 5, claim 7), even if there is an obstacle behind the ceiling, avoid the obstacle by merely shifting the position of the movable body. You can In addition, since the slide metal fitting is placed on the upper part of the device body, the material forming the side wall of the device body may be a relatively soft material such as aluminum, and it is not necessary to make the side wall vertical and the shape is free.
