Description

[Detailed Description of the Invention] [Purpose of the Invention] (Industrial Application Field) The present invention relates to a ceiling-mounted lighting fixture in which a cover is supported via a V-spring on a fixture body attached to the ceiling.

(Prior Art) In a ceiling-mounted lighting fixture, for example, as shown in FIGS. 4 and 5, V-springs 3 are attached via fixtures 2 to several locations around the fixture body 1 that is directly mounted to the ceiling. The ring portion 3a of the instrument body 1 is attached, and the spring ends 3b at both ends of the V spring 3 are attached via the support 6 to the frame 5 to which the peripheral edge of the cover 4 covering the instrument body 1 is attached. There is one in which a cover 4 is supported so as to cover the instrument body 1 by the spring action of a plurality of V-springs 3 attached at several locations.

The fixture 2 to be attached to the instrument body 1 is supported by fitting a ring portion 3a of a V spring 3 into a substantially U-shaped hook portion 2a provided at the tip. Later, for example, when unpacking during distribution and installing it on the ceiling surface, the V spring 3 is attached to the fixture 2, so the V spring 3 is attached between the tip of the hook part 2a and the bottom surface of the device main body 1. A gap is provided for attaching the ring portion 3a. However, if this continues, the ring portion 3a of the V spring 3 will come off from the gap between the tip of the hook 2a of the fixture 2 and the lower surface of the instrument body 1, so the stopper piece 7a at the tip will elastically move above the hook 2a. A stopper 7 is used which protrudes to prevent the V spring 3 from coming off. These fixtures 2 and stoppers 7 are integrally fixed to the instrument body 1 by rivets 8 which are caulked through fastening holes 9 provided in the instrument body 1.

(Problem to be solved by the invention) As mentioned above, in the conventional lighting equipment, in order to attach the ring part 3a of the V spring 3 to the equipment main body 1,
Two parts, the fixture 2 and the stopper 7, are required, and the number of man-hours required to attach these parts to the instrument body 1 increases, resulting in high costs.

The present invention was made in view of the above-mentioned problems, and an object of the present invention is to provide a lighting fixture in which a V-spring can be attached to the fixture body using only one part of the fixture.
