Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a frame structure for a lighting fixture that includes end plates and a body frame that intertwines between the end plates.

[Background technology]

Figures 4 and 5 show the frame structure of a conventional lighting fixture, and 1' in the figures indicates a flat plate approximately L.
The end plates are bent into a shape, and a set of two end plates are arranged facing each other with the upper piece 12 facing upward. Reference numeral 6' denotes a main body frame that intertwines both end plates 1', and the upper piece 1 of the end plate 1' is assembled using two main body frames 6'.
The end portion is fixed by caulking on the lower surface of 2 (A in the figure). Further, a metal fitting 13 for attaching a reflector is fixed to the lower surface of the upper piece 12 of the end plate 1' so as to be located between the main frame 6'. Reference numeral 14 denotes a U-shaped yoke, which is fixed to the main body frame 6' by caulking or screws so as to straddle both main body frames 6'. FIG. 5 shows a cross-sectional view of lighting fixtures arranged in an opening in the ceiling 15, in which 16 is a lamp, 17 is a reflector, and 18 is a panel. Reference numeral 19 denotes a frame for attaching to the opening edge of the ceiling 15. In such a conventional example, since the end plate 1' is approximately L-shaped, the strength of the end plate 1' itself cannot be obtained much, and the flat upper piece 12 of the end plate 1' and the body frame 6' Since it is simply fixed by caulking, it is not possible to secure much strength in the vertical and horizontal directions, and there is a problem that it is easily deformed.
Furthermore, it is necessary to attach the metal fittings 13 for attaching the reflector 17 to the end plate 1' as a separate member, which increases costs in terms of materials, assembly, etc.

[Purpose of invention]

The present invention has been proposed in view of the above-mentioned points, and it improves the strength of the attachment part between the end plate and the main body frame, and also improves the strength of the end plate itself. The object of the present invention is to provide a frame structure for a lighting fixture that uses common members without any problems.

[Disclosure of invention]

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
In addition, in FIGS. 1 to 3, unlike the conventional example, the vertical direction is reversed. Reference numeral 1 denotes an end plate, which is formed by bending a flat plate to have a substantially U-shaped cross section, as shown in FIG. The end plate 1 is formed with a tall vertical piece 20 located on the outside and a short vertical piece 3 located on the inside. Also,
A horizontal piece 4 is formed to extend horizontally over substantially the entire length in the longitudinal direction inward from the upper end edge of the vertical piece 3 (toward the opposing end plate 1 side). Reference numeral 5 denotes a notch cut across the vertical piece 3 and horizontal piece 4 of the end plate 1, into which an end portion of a body frame 6, which will be described later, is fitted. As shown in FIG. 3, the main body frame 6 has a substantially U-shaped cross section, and a contact piece 8 extends horizontally outward from the upper edge of both side pieces 7, 7.
are integrally formed. The width dimension of this main body frame 6 and the width dimension of the notch 5 are approximately the same dimension, and the main body frame 6
When inserted into the notch 5, the outer surfaces of the side pieces 7, 7 come into contact with the inner end surfaces of the notch 5, improving the strength in the left-right direction. Furthermore, a locking pawl 9 is formed, for example, by cutting and raising the center piece 2 of the end plate 1 at the approximate center thereof, and the main body frame 6 is fitted into the notch 5.
The longitudinal movement of the body frame 6 is restricted by locking the end edges of the body frame 6, and the body frame 6 and the end plates 1 on both sides are fixed together. Also,
At this time, the lower surface of the contact piece 8 of the main body frame 6 is brought into contact with the upper surface of the horizontal surface of the end plate 1, thereby improving the strength in the vertical direction. Further, the horizontal piece 4 of the end plate 1 is provided with a hole 10 for attaching a reflecting plate. Reference numeral 11 denotes a socket for mounting a lamp, which is attached to the central piece 2 of the end plate 1.

[Effect of idea]

As described above, in the frame structure of a lighting equipment, the present invention includes bending a flat end plate to have a substantially U-shaped cross section, and forming a horizontal piece extending inward from the upper edge of the inner vertical piece. A notch is cut in the end plate spanning the vertical piece and the horizontal piece, and the main body frame whose end is fitted into the notch is formed into a substantially U-shape. Contact pieces are formed extending horizontally from the upper edges of both sides of the body frame whose end surfaces are in contact with the outer surface, and which abut the upper surface of the horizontal plane of the end plate. In addition to forming a locking claw to lock the horizontal piece, the end plate itself is not L-shaped in cross section as in the past, but has a vertical piece and a horizontal piece. By providing a substantially U-shaped cross section, the strength of the end plate itself can be improved.
Moreover, by fitting the end of the main body frame into the notch of the end plate, and the end surfaces of the vertical and horizontal pieces on both sides of the main body frame are in contact with the outer surfaces of both sides of the main body frame, the end plate and the main body frame are brought into contact with each other. It is possible to improve the strength of the attachment part in the left and right direction.Furthermore, by abutting the contact piece of the main body frame on the upper surface of the horizontal piece of the end plate, the strength of the attachment part in the vertical direction can be improved. It has the advantage of being able to In addition, since the horizontal piece of the end plate has holes for mounting the reflector, the metal fittings for mounting the reflector can be omitted as in the past, reducing costs and making parts common. It has the advantage of being able to
