Abstract

(57) [Summary] [Purpose] The cost can be reduced by simplifying construction and reducing the number of parts. [Structure] A ceiling bar 1 having a wide width and an illumination lamp socket 22 attached to a lower surface thereof, and suspended from a side edge of the ceiling bar 1 installed in parallel or in a grid pattern, and a lower surface side of the ceiling bar 1. The support frame 3 also serves as a reflection plate for the illumination lamp 2 disposed in the above, and the ceiling material 4 is disposed with its side end portions supported by the support frame.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a system ceiling in which facilities such as ceiling materials and lighting equipment are attached to a suspended ceiling bar.

[0002]

[Prior Art]

 In the system ceiling, where ceiling materials are placed between ceiling bars that are suspended in parallel or in a grid pattern, lighting fixtures were also installed between the ceiling bars.

[0003]

[Problems to be solved by the device]

 In this case, the installation of the ceiling bar and the installation of the lighting equipment will be done by separate work, and it will take a long time for the construction and the construction period will be long, and parts for installing the lighting equipment between the ceiling bars will be required. Therefore, the cost is high. The present invention has been made in view of such a point, and an object of the present invention is to provide a system tray which can reduce the cost by simplifying the process and reducing the number of parts.

[0004]

[Means for Solving the Problems]

 The present invention, therefore, has a wide ceiling bar on which the sockets for lighting lamps are attached to the lower surface, and the ceiling bar that is suspended from the side edges of the ceiling bars that are installed in parallel or in a grid pattern and that is mounted on the lower surface side of the ceiling bar. It is characterized in that it is composed of a support frame that also serves as a reflector for the illumination lamps that are arranged, and a ceiling material that is arranged with its side end portions supported by the support frame.

[0005]

[Action]

 According to the present invention, a member for mounting a lighting fixture between ceiling bars because the supporting frame for supporting the ceiling material also functions as a reflector for lighting, in addition to directly mounting the lighting lamp on the ceiling bar. No need for reflectors in lighting fixtures.

[0006]

【Example】

 The present invention will be described in detail below with reference to the illustrated embodiment. As shown in FIG. 1, here, a ceiling bar 1 having a U-shape and a wide base is used. The ceiling bar 1 installed by hanging in parallel or in a grid pattern has the ballast 21 for the illumination lamp 2 attached to the upper surface thereof and the socket 22 attached to the lower surface thereof. It is directly attached to the ceiling bar 1 itself without using a separate member. In addition, air-conditioning return holes 12 for indoor ventilation are formed at appropriate intervals on the bottom side of the ceiling bar 1, and the upper surface of the ceiling bar 1 is a space for passing the indoor wiring 5.

A support frame 3 is attached to the side edge of the ceiling bar 1. As shown in FIG. 2, the supporting frame 3 has a supporting piece 30 protruding in the horizontal direction at the lower end edge, and an engaging piece 31 hooked on the ceiling bar 1 at the upper end edge. The ceiling member 4 formed in a shape is arranged by mounting the end portion on the support piece 30 of the support frame 3. The side of the support frame 3 facing the illumination lamp 2 arranged on the lower surface of the ceiling bar 1 is finished with white coating so as to function as a reflection plate. The supporting frame 3 may have a sectional shape shown in FIGS. 3 (a) and 3 (b). The function as a reflector can be further enhanced.

In this system ceiling, the wiring work for lighting can be completed when the ceiling bar 1 is attached, and then the support frame 3 and the ceiling material 4 are attached. The lighting lamp 2 may be installed sequentially and finally, and no additional work for installing the lighting fixture is required. In the embodiment shown in FIG. 4, a slit hole 33 for mounting the louver 25 arranged below the illumination lamp 2 is provided in the lower portion of the support frame 3 so that the louver 25 can be attached and detached. ..

The groove on the lower surface of the ceiling bar 1 which is surrounded by the support frames 3 and 3 and which opens downward is used for partitioning as it fits the upper part of the partition for partitioning.

[0010]

[Effect of the device]

 As described above, in the present invention, since the lighting lamp socket is provided on the lower surface of the ceiling bar and the lighting lamp is directly attached to the ceiling bar, a member for installing the lighting fixture between the ceiling bars is unnecessary. In addition, the wiring work for lighting equipment can be completed when the ceiling bar is installed, and the ceiling material is hung from the side edges of the above-mentioned ceiling bars installed in parallel or in a grid pattern. Since the supporting frame that supports it also serves as the reflector for the illumination lamp, there is no need for a separate reflector.For this reason, the cost can be reduced by simplifying the construction and reducing the number of parts. Is something that can be done.
