However, in the above-described mounting structure of the reflector using the decorative screw, the decorative screw must be rotated, and the rotary operation is performed on a high ceiling such as a room. Difficulty accompanies the fact that the reflection plate must be positioned and pressed against the main body while being pressed. If the hand is wrong when the cosmetic screw is attached, the cosmetic screw may be dropped, and the workability is extremely poor, and the installation man-hour is required. In addition, even though it was a cosmetic screw, the appearance was not good because it was projected from the mounting surface of the reflector.

Therefore, as another mounting structure of the reflecting plate in consideration of these problems, as shown in FIGS. 13 (a) and 13 (b), a reflecting plate 43 is attached to a receiving member 42 provided on the instrument body 41. By inserting the locking member 44 from

On the other hand, the locking member 16 is shown in FIGS.
As shown in FIG. 8D and FIGS.
A hook portion 19 is formed in series at the tip of a shaft portion 18 extending integrally from a metal core 20 and the metal core 20.
And a resin material 21 that covers a part thereof. The knob portion 17 is formed in a predetermined shape with a resin material 21 covering the core member 20, that is, when the locking member 16 is attached to the reflection plate 2, the knob portion 17 is formed on the ridgeline surface 22 of the reflection plate 2. Ridge-shaped surface 22 of the reflection plate 2
And a ridge line-shaped surface 32 (see FIGS. 1 and 9B). In addition, a concave groove 26 is formed on the back surface of the knob portion 17 so that a convex portion 25 provided on a flat surface 24 of a concave portion 23 of the reflecting plate 2 described later enters.

At a position directly below the knob 17 of the shaft 18,
A projecting portion 27 is formed of the resin material 21 with a slight gap between the knob 17 and the reflecting plate 2 so that the projecting portion 27 projects in a direction perpendicular to the longitudinal direction of the reflecting plate 2. ing. The shaft portion 18 has a circular section 33 in which approximately half of the knob portion side has a circular cross section and a predetermined outer diameter, and a rectangular cross section in which approximately half of the hook portion side partially exposes the core material 20. The side is constituted by a rectangular portion 34 having a predetermined dimension. The hook 19 located at the tip of the shaft 18 is made of a core material 20 having an equilateral triangle that widens toward the shaft 18 and becomes narrower with the shaft 18.
Like the above-mentioned projection 27, it has a shape protruding in a direction orthogonal to the longitudinal direction of the reflection plate 2.

9 (a) to 9 (c), the knob 17 of the above-described locking member 16 enters the portion of the reflection plate 2 (see FIG. 3) facing the receiving member of the ridge 22. The recess 23 is formed by, for example, drawing, and a long hole 28 is formed in the flat surface 24 formed in the recess 23 along the width direction of the reflector 2. The flat surface 24 is formed with a convex portion 25 which is positioned by being inserted into a concave groove 26 formed on the back surface of the knob 17 of the locking member 16 described above. A bulging portion 29 protruding to the rear surface side is formed, and when the locking member 16 is attached to the reflecting plate 2, the protruding portion 27 comes into contact with the bulging portion 29 so that the locking member 16 with respect to the reflecting plate 2 is removed. I try to suppress the rattling.

In the present invention, the procedure for attaching the reflection plate 2 to the instrument body 1 is as follows.

First, prior to attaching the reflector 2 to the instrument body 1, a locking member 16 is attached to the reflector 2 in advance. That is, the locking member 16 is inserted into the elongated hole 28 formed in the concave portion 22 of the reflection plate 2. At this time, by inserting the knob 16 of the locking member 15 in the direction orthogonal to the longitudinal direction of the reflector 2, the hook 19 and the shaft at the tip of the shaft 18 of the locking member 16 are inserted. The protrusion 27 at the base end of 18 can be inserted into the elongated hole 28,
The knob 17 of the locking member 16 is rotated by 90 °.

As a result, as shown in FIG. 10, the concave portion 23 of the reflection plate 2 is sandwiched between the knob 17 and the projection 27 of the locking member 16, and the locking member 16 is supported by the reflection plate 2. Is done. At this time, the concave groove 2 on the back surface of the knob 17
6 is a projection 25 on the flat surface 24 of the recess 23 of the reflector 2.
Enters and restricts the rotation direction of the locking member 16 for positioning. In addition, the bulging portion 29 on the flat surface 24 of the concave portion 23 of the reflection plate 2 abuts on the projection 27 of the locking member 16, thereby preventing the locking member 16 from rattling with the reflection plate 2. In this state, the knob 17
In FIG. 1, the ridge-shaped surface 32 which is the outer surface thereof is flush with the ridge-shaped surface 22 of the reflection plate 2 (see FIGS. 1 and 9B).
Also, the hook 1 at the tip of the shaft 18 of the locking member 16
Reference numeral 9 is oriented so as to project in a direction orthogonal to the longitudinal direction of the reflection plate 2.

The reflecting plate 2 to which the locking member 16 is attached in advance in this way is used to connect the fixture main body 1 attached to the ceiling.
Align and press. The reflector 2 is attached to the instrument body 1 only by this pressing. That is, the hook 19 at the tip of the locking member 16 of the reflection plate 2
However, first, the pores 1 intersecting at the center of the long holes 14 of the cover 11
5 is inserted. At this time, since the guide 11 is guided to the mortar-shaped guide surface 13 of the cover 11, the hook 1
9 is smoothly inserted into the above-mentioned pore 15.

Thereafter, the hook 19 of the locking member 16 comes into contact with the inner bent portion 8 of the receiving member 5. By the pressing of the reflector 2, the hook 19 tries to push the inwardly bent portion 8 of the receiving member 5 outward as shown in FIG. 11, and the side plate 7 of the receiving member 5 first resists the elastic force. And spread outward. When the side plate 7 is expanded to some extent, the deformation is restricted by contacting the cover 11, and thereafter, the inner folded portion 8 is deformed against the elastic force, and the inner folded portion 8 and the outer folded portion 9 are deformed. , The narrow gap m between the opposing bent portions 10 is increased.

When the hook portion 19 passes through the gap m, the inward folded portion 8 and the side plate portion 7 return to the original state by the elastic force as shown in FIG. Thus, the locking member 1
When the hooking portion 19 passes through the gap m between the opposing bent portions 10, the hooking portion 19 comes into contact with the outer folded portion 9 and is hooked, and the locking member The reflection plate 2 is attached to the instrument body 1 by 16.

At this time, in the shaft portion 18 of the locking member 16, since the rectangular portion 34 located on the hook portion side has a rectangular cross section, the portion between the inner folded portion 8 and the outer folded portion 9 of the receiving member 5 is formed. Bending part 1
Since it is in line contact with 0, the locking member 16 does not rattle in the rotational direction. Further, since the circular portion 33 located on the knob side has a circular cross section, the elongated hole 1 of the cover 11 is formed.
The position shift is regulated by the round hole 35 at the intersection of the hole 4 and the fine hole 15.

Further, since the receiving member 5 is surrounded by the cover 11, even if the hook 19 of the locking member 16 tries to come off from the receiving member 5 after the mounting of the reflecting plate 2, Since the cover 11 regulates the side plate 7 from expanding, the side plate 7 does not expand. As a result,
Since the hook portion 19 of the locking member 16 does not fall out of the gap m between the bent portions 10 of the receiving member 5, the fall of the reflection plate 2 is reliably prevented.

The removal of the reflector 2 from the instrument body 1 may be performed in the following manner.

First, the knob 16 of the locking member 16 is
By rotating the shaft member 18 of the locking member 16.
The hook 19 at the tip of the device is rotated by 90 ° so that the extending direction thereof is along the longitudinal direction of the instrument body 1. This allows the hooking portion 19 of the locking member 16 to pass through the gap m between the opposing bent portions 10 of the receiving member 5. Therefore, since the hooking state of the locking member 16 on the receiving member 5 is released, the reflection plate 2 can be removed from the instrument body 1.

In the above embodiment, the ceiling-mounted lighting fixture in which the fixture main body 1 is mounted on the ceiling has been described. However, the present invention is not limited to this, and for example, the fixture main body 1 is mounted on the ceiling. The present invention is also applicable to a case where the reflection plate 2 is attached while being suspended.

[0032]

According to the present invention, it is possible to reliably prevent the locking member from being pulled out of the receiving member by the cover when the reflector is mounted on the instrument body. When mounted on the main body, the locking member can be smoothly inserted into the receiving member by the guide surface of the cover, and its workability has been greatly improved, especially when mounting on a high ceiling such as indoors, It can be easily and quickly attached to the instrument body, and its practical value is very large.
