Abstract

PURPOSE:To prevent the dropping of an accessory and keep safety by fixing an architrave-shaped frame folded with the outer periphery to the outside to a reverse T-shaped ceiling beam or an apparatus main body, and fitting the accessory such as a louver to the architrave-shaped frame. CONSTITUTION:An accessory fitting frame 6 formed into a rectangular architrave-shape is fitted with a fixing metal 6a via T bars 1, and the fitting metal 7a of the frame 7 of an accessory 5 is hooked and fitted to a fitting hole 6a provided on the frame 6. Since the frame 6 is formed into the architrave-shape, even if the interval between the T bars 1 has a slight error due to construction, its effect is not inflicted, and the accessory 5 can be stably fitted. Folded pieces of a facility plate 4 to be mounted on the T bars 1 and folded pieces 4a to be mounted on the frame 6 are mounted and held respectively, the facility plate 4 is not dropped when vibration occurs during an earthquake, and safety can be maintained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a structure for mounting accessories such as louvers in system ceiling lighting equipment.

[Conventional technology]

The Oa lighting fixtures for people's wells are installed on a ceiling beam with an inverted T-shape (hereinafter referred to as a T-bar) that extends over the ceiling with a 1-inch leg that connects sockets and lighting devices. When using the above lighting equipment with a louver, translucent cover, etc. installed: i, VJ
As shown in FIGS. 7 and 8, conventionally, a mounting bracket R1O has been mounted on the T-bar I in order to attach the accessory 5. The above mounting bracket 10 is the mounting bracket 9 of the p3 light fixture.
The normal structure is to use the above T-bar 1 to place the equipment plate on which speakers, anemones, etc. are attached. The direction was such that it butted against the accessory frame 7 as shown in FIG.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, the accessory mounting brackets are mounted and held on the T-bars, but since the T-bars are constructed during construction work, it is extremely difficult to maintain accurate spacing between them. Moreover, the interval between images can easily change due to earthquakes, etc.
If the distance between them were to widen a little, there was a possibility that the louver or other accessories would fall off and fall, which would pose a reliability problem. Moreover, the above-mentioned falling off is not limited to only accessories, but also the above-mentioned equipment plate.

[Means to solve the problem]

To solve the above problems, the present invention has a structure in which a frame-shaped accessory mounting frame with the outer periphery bent outward is fixed to the T-shape or the instrument body, and accessories such as louvers are attached to the frame-shaped accessory mounting frame. This is what I did.

[Effect]

By providing an accessory mounting frame whose outer periphery is bent outward to form an n-edge shape, fixing the mounting frame to the T-bar or the instrument body, and attaching the accessory to the mounting frame,
It is possible to prevent the above-mentioned accessories from falling off due to a defect in the T-bar spacing. Furthermore, by bending the outer periphery of the mounting bracket outward, the part of the equipment plate adjacent to the lighting fixture is locked to the bent piece of the mounting bracket, so the equipment plate is Each side of the surrounding area will be supported individually, 111! Safety can be improved even when exposed to vibrations such as earthquakes.

〔Example〕

Embodiments of the present invention will now be described with reference to the drawings.

Fig. 1 is an exploded perspective view showing one embodiment of the accessory mounting structure for a system ceiling lighting fixture according to the present invention; Fig. 2 is a partial perspective view of the equipment plate and accessory mounting frame;
The figure is a half-sectional view of a system ceiling lighting fixture with and without accessories installed, Figure 4 is a vertical cross-sectional view of the main part of the above lighting fixture with accessories installed, and Figure 5 is an enlarged cross-sectional view of the main part of the above-mentioned elucidation fixture. Figures 16 and 16 are enlarged views of the main parts of the above longitudinal cross-sectional view. The lighting fixture of the present invention, as shown in FIG.
A fixture main body 2 having a lighting device including a ballast box 3, a socket, etc., and a height-adjustable mounting leg is mounted on a ceiling over which a T-bar 1 having an inverted T-shaped cross section is passed in parallel. It has a structure in which it is supported on the T-bar 1 by a 1-inch leg (see FIG. 5, B?) attached to the instrument main body 2. In addition to the above-mentioned lighting equipment, an equipment bracket is attached to the gap formed by the two T-bars 1 to allow installation of equipment such as speakers and anemones. When the above-mentioned lighting equipment is used with an open-bottom lighting fixture, as shown in the left half of Fig. 3, the lower end of the reflector 8 is in contact with the T-bar 1. For example, a louver, etc. When using accessory 5 of
Adjust the mounting position of the mounting leg 9 as shown in the left half of the figure,
A gap is provided between the T-bar 1 and the lower end of the reflector plate 8, and the accessory 5 is attached between the gaps. To attach the accessory 5, as shown in FIG. 1, an accessory attachment frame 6 formed in the shape of a rectangular frame is fixed with a fixing bracket 6a using the T-bar 1 or the appliance attachment bracket 9 of the appliance body. ,
A mounting bracket 7a of the frame 7 of the accessory 5 is locked and mounted in a mounting hole 6b provided in the accessory mounting frame 6. Since the accessory mounting frame 6 is formed in the shape of a rectangular picture frame, the accessory 5 can be stably mounted without being affected even if there is some error in the spacing between the T-bars 1 due to construction. I can cut it down by 1 inch.

In addition, the accessory mounting frame 6 is as shown in FIG.
Since the outer periphery of the mounting frame 6 is bent outward and has a rising edge, the equipment plate 4 that is attached adjacent to the lighting fixture can be attached to the tips 4 of the rising parts at both ends as shown in the figure.
4 of the equipment plate 4 by bending and forming a.
The entire periphery has a bent piece, and the bent part of the tip 4a of the rising part can be mounted on the edge of the accessory mounting frame 6 of the adjacent lighting fixture, and the equipment plate 4
, the bent piece mounted on the T-bar 1 and the accessory mounting frame 6
Since the bent pieces 4a mounted on the racks are respectively mounted and held, safety can be maintained without falling even if vibrations such as an earthquake occur.

According to the present invention, accessories can be attached to the T-bar 1 installed during construction without being affected by the dimensional accuracy of the spacing, and the equipment plate is also reliably supported. can be improved.
