Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recessed lighting fixture, for example, a so-called recessed downlight, and relates to a structure for supporting a frame body provided with a baffle portion that is attached to a support frame so as to be movable forward and backward.

As shown in FIGS. 1 and 2, a conventional recessed lighting fixture of this type has a frame body 4 with a baffle portion 3 integrally attached to a support frame 2 provided with a lamp socket 1, so that the frame body 4 can be moved forward and backward. , a structure is adopted in which both side rod portions 6 of a substantially V-shaped locking spring body 5 attached to the frame body 4 are slidably locked to locking portions 7 provided on the support frame 2.

Conventionally, a mounting bracket 8 is fixed to a plurality of locations on the inner surface of the frame body 4 by spot welding, and a winding portion is formed around the center of the approximately V-shaped locking spring body 5 around the mounting bracket 8. Because of the structure in which the hook fitting 10 that holds the mounting bracket 9 is screwed or caulked, uneven welding marks are formed on the part of the frame 4 where the mounting fitting 8 is welded, which impairs the appearance and requires polishing. In addition, since the hook fitting 10 is attached to the mounting fitting 8, the assembly process requires a large number of man-hours and time, and the tip holding piece 11 of the hook fitting 10 is bent to hold the locking spring body 5, which requires assembly work. It has some disadvantages.

Furthermore, since the mounting bracket 8 is spot welded, its tensile strength is low due to variations in welding work, and if the baffle portion 3 is moved back and forth frequently, there is a risk that the spot weld will peel off and the frame 4 will fall off the support frame 2. It has certain drawbacks.

The present invention was developed in view of the above-mentioned drawbacks, and includes a plurality of holding parts bent in an annular holding spring body that is fitted and locked in an annular recess formed on the outer periphery of a baffle part integrated with the frame body. The purpose of the present invention is to provide an embedded lighting fixture in which a winding part of a locking spring body is engaged with this holding part, thereby reducing the number of parts, improving ease of assembly, and securely holding a frame body. .

Next, the structure of an embodiment of the present invention will be explained with reference to FIGS. 3 to 5.

Reference numeral 12 denotes a support frame, which is formed into a substantially inverted U-shape, with a lamp socket 14 attached to the top side 13, and locking pieces 15 fixed to both vertical sides 30 near the lower end of the inner surface. There is.

This locking piece 15 is formed with a locking portion 32 that is inclined in a direction that extends from the notch opening 31 on both sides.

Also, mounting pieces 27 are formed on the outer surfaces of both vertical sides 30 of the support frame 12 to fix the support frame 12 to a ceiling member.

Next, a frame 16 is formed into an annular brim shape, and a substantially cylindrical baffle portion 17 is integrally formed from the inner periphery of this frame 16, and this baffle portion 17 has an annular recess 18 extending in the axial direction. A large number of them are formed in parallel, and the inner surface has an uneven surface 2 that enhances the reflection effect.
8.

Next, reference numeral 19 denotes a holding spring body, which is formed in an annular shape from an elastic wire material, and on both sides of this holding spring body 19, holding parts 20 are respectively bent so as to protrude outward in a substantially U-shape. It is formed.

A locking holding part 21 bent downward is formed on the distal end side of this holding part 20.

Next, reference numeral 22 denotes a locking spring body, which is made by bending an elastic wire into a substantially V-shape, and an annular winding part 23 is formed in the middle part. It is designed to be held consistent at 20.

Both side rod portions 24 of this locking spring body 22 are slidably locked to locking portions 32 of the support frame 12.

Next, the operation of this embodiment will be explained.

The holding spring body 19 is attached to the baffle part 17 of the frame body 16 on the holding part 2.
Fit the baffle part 1 while expanding the inner diameter with a spring force of 0.
7, the inner diameter of the holding spring body 19 is reduced by the elasticity of the holding part 20, and this holding spring body 1
9 is locked in the annular recess 18 of the baffle portion 17.

Next, the winding portion 23 of the locking spring body 22 is fitted and held in the holding portion 20 of the holding spring body 19.

The winding portion 23 is prevented from being pulled out by the locking and holding portion 21.

Next, the rods 24 on both sides of the locking spring body 19 are slidably locked in the locking portions 32 of the locking piece 5 of the support frame 12, and when the frame 16 is pushed up, the baffle portion 17 is supported. The frame body 16 surrounds the lamp 29 attached to the lamp socket I/14 of the frame 12 and is locked to the lower surface of the support frame 12.

At this time, the holding spring body 19 is attached to the annular recess 1 of the baffle portion 17.
8 and holds the baffle portion 17 around the entire circumference.

Further, when the frame body 16 is pulled downward, the locking spring body 22 is pinched between the rod portions 24 on both sides against the spring force, and the baffle portion 17 can be pulled out from the support frame 12.

According to the present invention, the annular retaining spring body that is engaged with the four annular parts of the baffle part that is integrally provided with the frame body has a plurality of bent retaining parts that protrude outward. Since the wound portion of the approximately V-shaped locking spring body is engaged, the holding spring body can support the weight of the frame body having the baffle part around the entire circumference of the baffle part, and can hold the frame body reliably and safely. , Even if the frame body is frequently attached and detached, no load is applied locally, there is no need for a member to hold the retaining spring body, the number of parts is small, assembly man-hours are reduced, and it can be manufactured at low cost. It does not require spot welding and can provide uniform quality.
