JPH0893120A - Plate for installing luminair - Google Patents

Abstract

PURPOSE: To reduce the time required to fit an installation plate, by providing a bar for fixing the installation plate to a ceiling face and metal fittings to fasten it, in the installation plate between luminairs, installed to simplify the ceiling face. CONSTITUTION: A fixing bolt 3 is inserted in the center hole of a bar 1 and a metal hook 4 and a butterfly nut 2 is temporarily fastened and the metal hook 4 temporarily fixed in the screw hole 5a of the metal fittings 5 welded with the installation plate 6 on fitting the luminair, is fastened with two screws 7. When fitting the installation plate to the ceiling, the body is inserted from the side where the luminair is not fixed and the bar 1 is placed on the channel 8a in the inside face of ceiling and the butterfly nut 2 is fastened to fix the installation plate 6. In this way, the bar 1 is hooked on the channel 8a and the plate can be fixed by the metal fittings 5 and two screws 7 through the bolt 3 and the metal hook 4 and hence, the fitting time of the plate can be reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixture plate for a ceiling-mounted luminaire.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, an equipment plate is attached to a box-shaped main body, and the equipment plate main body is attached with an insert bolt after being screwed with a connecting metal fitting between lighting fixtures.

[0003]

In the above-mentioned prior art, in consideration of workability, there is no consideration regarding work saving such as fixing the equipment plate between the lighting fixtures with the connecting metal fittings and fixing with the insert bolt from the ceiling. was there. An object of the present invention is to provide a low-priced equipment plate by shortening the installation time of the equipment plate.

[0004]

In order to achieve the above object, the present invention provides a bar for mounting an equipment plate and eliminates the hook insert bolt on the inner surface of the ceiling. Also, the equipment plate body was abolished.

[0005]

The bar on the equipment plate that serves as a spacer for the lighting fixture can be fixed to the ceiling channel on the inner surface of the ceiling by using the fixing bolts and the hooking metal fittings and the two screws on the equipment plate. Also, by tightening the wing nut of the fixing bolt by hand, even if the size of the ceiling channel changes, the same parts can be used. In addition, a cut-and-raised metal is provided in the hook to prevent rotation of the fixing bolt, and the vertical movement of the hexagonal nut portion at the tip of the fixing bolt can be stopped simultaneously by tightening two screws. Also, the bar,
By setting the fixing bolts, hooks, etc., and separating them from the equipment plate side, the size when packaging the plates can be reduced. Further, the plate and the hook metal fitting are fixed by using two screws, but one of the screws can be used as a latch type to save the work.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be described. The fixing bolts 3 are inserted into the central holes of the bar 1 and the hooks 4, the wing nuts are temporarily fixed, and the hooks temporarily fixed to the screw holes 5a of the fittings 5 welded to the equipment plate 6 when the fixture 9 is attached. 4 is fixed with two screws 7, and the assembly is completed. At the time of mounting on the ceiling, the body or hand is put from the side where the lighting fixture is not mounted, and the bar 1 is placed on the ceiling inner surface channel 8a and the wing nut 2 is tightened as shown in FIG. According to this embodiment, the equipment plate can be easily attached, and the weight is light, so that the construction can be saved.

[0007]

According to the present invention, since the hooking metal fittings, bolts, bars, etc. are set and separated from the equipment plate, the packaging can be made small and inexpensive, and the main body of the equipment plate is abolished. It is possible to reduce the construction work and the cost. Furthermore, since the metal fittings and the like can be eliminated, the construction work and the cost are reduced. Further, since it is not necessary to construct the anchor bolt, the construction period can be shortened.
