Description

[Detailed explanation of the idea] The present invention relates to a recessed lighting fixture.

Conventionally, as a structure for attaching to the lower frame of a recessed lighting device, for example, as shown in Japanese Utility Model Application Publication No. 53-86880, a spring receiving piece 14 is cut directly from the side plate 3 to lock a V-shaped spring. Or, Jitsukō 51-20621
As shown in the above publication, a spring receiver 6 having an L-shaped cross section is fixed to the inner surface of both side walls of the main body 1 to lock a V-shaped spring 13. However, in the former case, the strength of the side plate part 3 is reduced due to the hole formed after cutting and raising the spring receiving piece 14, and in the latter case, although there is no risk of the strength being reduced as in the former case, the spring receiving body 6 is made as a separate component. This increases the cost, and there is a problem that the position of the locked spring 13 may move due to the width of the spring receiver 6.

The present invention has been made in view of the above-mentioned background, and an object of the present invention is to easily and firmly attach the lower frame of a recessed lighting device.

The present invention will be explained below based on the embodiments shown in FIGS. 1 to 4.

This recessed lighting fixture has a hole in the ceiling 1 and a main body 2 is attached using a claw metal fitting 3.
A reflector plate 4 and a lower frame 5 are attached to the frame. The main body 2 has leg pieces 7 projecting downward from both sides of the top plate 6, and claw metal fittings 3 projecting outward from the leg pieces 7 are attached to the leg pieces 7 so as to be movable and fixed in the vertical direction. It is fixed and attached to the back of ceiling 1.
Further, a reflection plate 4 provided with a spring 8 is detachably latched to the top plate 6. At both ends of the leg piece 7, guide pieces 10 having a substantially doglegged cross section are provided upwardly from the vicinity of the lower end and projecting into the main body 2 from both side edges of the flat plate part 9.
The doglegged bent portion of the guide piece 10 is located at the most lateral side of the leg piece 7, and the free end of the guide piece 10 is located inward from the doglegged bent portion. Flat plate part 9 of leg piece 7
A vertical hole 11 is provided in which a claw metal fitting 3 is movably engaged, and a slit 12 is formed in a dogleg-shaped bent portion of the guide piece 10. The lower frame 5 has a spring 13 which is bent at its tip and has a width near the tip that is wider than the interval between the double-legged bent portions of the guide pieces 10, 10.
is rotatably attached, and the lower frame 5 is locked to the main body 2 by a spring 13. The spring 13 is inserted into the slit 12 with the lower frame 5 locked to the main body 2.
The width of the portion that is engaged with the lower end of the free state is wider than the interval between the double-legged bent portions;
It is inserted from below into the dogleg-shaped bent part of the guide piece 10 of the leg piece 7 in a reduced width state, is pushed upward and fitted into the slit 12, and is elastically expanded and inserted and locked into the slit 12. Ru. And the lower frame 5 is the leg piece 7
It is removably locked to. At this time, the spring 13 is
Since the guide piece 10 has a substantially doglegged cross section, it can be positioned at the doglegged bend by simply inserting it from below, and the slit 1
2, and in the locked state, its position is determined by the slit 12, and it is separated from the flat plate part 9 and is locked in the hole 11 of the flat plate part 9, avoiding the claw metal fitting 3.

In this way, the recessed lighting fixture according to the present invention is
Guide pieces with a substantially doglegged cross section are provided on both ends of the leg pieces to protrude into the main body, and a spring attached to the lower frame is inserted and locked into the slit provided in the doglegged bent part of the guide piece. A guide piece with a dogleg-shaped cross section is provided on the leg piece, which improves the strength of the leg piece, and since the guide piece has a roughly dogleg-like cross section, the spring can be positioned at the dogleg-shaped bend by simply inserting it from below. The lower frame is guided to the slit, and when it becomes locked, the position is determined by the slit, avoiding the claw metal fittings locked to the leg pieces, and the lower frame can be installed easily and firmly. .

Claims (1)

[Scope of utility model registration request] The main body is fixed to the back surface of the ceiling with claw metal fittings protruding outward so that it can be moved up and down and fixed freely on the leg pieces, and at both ends of the leg pieces there are guides bent upward from the vicinity of the lower end in a dogleg shape in cross section. A piece is provided to protrude into the main body, and the dogleg-shaped bent portion of the guide piece is located at the most lateral side of the leg piece, and the free end of the guide piece is located inward from the doglegged bent portion. A slit is provided in the dogleg-shaped bent portion of the guide piece, and a spring that is attached to the lower frame and locks the lower frame to the main body has a free portion that locks at the lower end of the slit in the locked state. The embedding device is characterized in that the width in this state is wider than the interval between the doglegged bent portions, and the spring is inserted into the doglegged bent portion and inserted and locked into the slit. type lighting equipment.
