JPH06187815A - Device for mounting reflecting plate of luminaire - Google Patents

Abstract

PURPOSE:To easily mount a reflecting plate on the inside of a frame without causing rattling by inserting a spring of specific shape into a hole provided in the upright piece of the frame and into a notch or hole provided in the flange portion of the reflecting plate. CONSTITUTION:A spring 5, having a folded portion 6 at one end for insertion into a hole 4 provided in the upright piece 3 of a frame 1, rises along the inner surface of the upright piece 3, and the inside portion of the spring 5 lowered therefrom is pressed against the outer surface of a reflecting plate 2 by means of a portion 7 curved toward the reflecting plate 2. Thereby a transverse backlash between the reflecting plate and the frame can be prevented. A narrow portion 8 provided at the other end of the spring 5 is inserted into a notch 10 (or hole) provided in the flange portion 9 of the reflecting plate 2 and the flange portion 9 is pressed against the main part of the narrow portion 8 between a transversely-extending holding portion 11 and the inward piece 12 of the frame 1. Thereby a lateral backlash between the frame 1 and the reflecting plate 2 can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reflector mounting device for a lighting fixture having a structure for mounting a reflector inside a frame.

[0002]

2. Description of the Related Art Heretofore, in general, a screw or a cut-and-raised nail is generally used to mount a reflector on the inside of a frame.

[0003]

However, the above-mentioned conventional techniques have problems that the assembly is troublesome and rattling is likely to occur. SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and provide a reflector mounting device for a lighting fixture having a structure for mounting a reflector inside a frame easily and without rattling.

[0004]

According to the present invention, a reflector is attached to the inside of a frame, and a bent portion at one end of a spring is inserted into a hole provided in an upright piece of the frame, and the bent portion is attached to the bent portion. One end side of the continuous spring rises along the inner surface of the standing piece, and the inner part of the spring which is lowered from there is bent toward the reflector plate to press the outer surface of the reflector plate and reflect the narrow part of the other end of the spring. Configure a reflector mounting device for lighting fixtures that is inserted into a notch or hole provided in the flange part of the plate and that holds the flange part between the inward piece of the frame and the pressing part that spreads laterally at the base of the narrow part .

[0005]

According to the present invention, one end side of the spring connected to the bent portion rises along the inner surface of the standing piece, and the inner portion of the spring lowered from that is bent to the reflector side by the bent portion of the reflector plate. Since the outer surface is pressed, it is possible to prevent rattling in the lateral direction between the frame and the reflector. Also, insert the bent part of one end of the spring into the hole provided in the standing piece of the frame, insert the narrow part at the other end of the spring into the notch or hole provided in the flange part of the reflector, and insert it into the base of the narrow part. Since the brim is pressed against the inwardly facing piece of the frame by the laterally pressing portion, it is possible to prevent vertical rattling between the frame and the reflector.

[0006]

Embodiments of the present invention will be described with reference to the drawings.

In this embodiment, the reflector 2 is mounted inside the frame 1, and the bent portion 6 at one end of the spring 5 is inserted into the hole 4 formed in the upright piece 3 of the frame 1 to bend the frame. One end side of the spring 5 connected to the portion 6 rises along the inner surface of the standing piece 3, and the inner portion of the spring 5 that is lowered from there is bent to the side of the reflection plate 2 to press the outer surface of the reflection plate 2, Narrow part 8 at the other end of spring 5
Is inserted into the notch 10 (or hole) provided in the collar portion 9 of the reflection plate 2, and the collar portion 9 is formed between the inwardly facing piece 12 of the frame 1 by the pressing portion 11 that spreads laterally at the base of the narrow portion 8. Holding down. Although the frame 1 and the reflector 2 have a circular shape, the drawings are shown as the main parts.

According to this embodiment, one end of the spring 5 connected to the bent portion 6 rises along the inner surface of the standing piece 3, and the inner portion of the spring 5 that is lowered from there is bent to the reflector 2 side. Since the outer surface of the reflector 2 is pressed by the bent portion 7, the frame 1 and the reflector 2
Mutual rattling in the lateral direction can be prevented. Further, the bent portion 6 at one end of the spring 5 is inserted into the hole 4 provided in the upright piece 3 of the frame 1, and the narrow width portion 8 at the other end of the spring 5 is provided in the flange portion 9 of the reflection plate 2 with the cutout 10 ( Or a hole), and the collar portion 9 is pressed between the frame 1 and the inwardly facing piece 12 of the frame 1 by the pressing portion 11 that spreads laterally on the base of the narrow portion 8. It can prevent rattling.

[0009]

As described above, according to the present invention, it is possible to easily attach the reflector to the inside of the frame without rattling.
