Description

[Detailed explanation of the idea] (Industrial application field) This invention relates to lighting equipment.

(Prior Art) Lighting devices that are composed of a main body and a cover such as a translucent panel or louver that covers a fluorescent lamp or the like installed on the surface of the device are already well known. ing. Usually, this type of cover is supported by a rectangular frame, which is elastically attached to the appliance body fixed to the ceiling or the like using a V-shaped spring.

For example, in a recessed lighting fixture, the central winding of the spring is connected to the frame.
The frame is attached to the instrument body by engaging the legs with spring receivers fixed to the side wall of the instrument body.

FIG. 6 shows the configuration of such a lighting fixture previously proposed by the present inventor, in which 1 is the main body of the fixture to be embedded in the ceiling, etc., 1A is the side wall of the fixture,
Reference numeral 2 denotes a cover like a translucent panel, the periphery of which is supported by a square-shaped frame 3.

A V-shaped stiff spring 4 is connected to the frame 3 at its central winding portion 5 via a connecting fitting 6, and its legs 7 on both sides are connected to spring holders fixed to the side wall of the device body 1. 8, the frame 3 is elastically attached to the instrument body 1.

The spring receiver 8 is constituted by a gutter-shaped metal fitting having a U-shaped cross section. The lower end edge 8A is installed at a location close to the lower end edge 1B of the instrument main body 1. This installation position is such that the lower edge 8A can be directly seen from the lower end of the instrument main body 1.

To engage the tight spring 4 with the spring receiver 8,
First, the tip of the leg 7 is inserted into the spring receiver 8. This insertion operation is performed on the lower edge 8A of the spring receiver 8.
This is extremely easy since it is located close to the lower edge 1B of the instrument body 1 and can be visually observed.

When the frame 3 is then pushed up and the tips of the legs 7 escape from the spring receivers 8, the legs 7 elastically expand and engage with the upper edge of the spring receivers 8 as shown in the figure. As a result, the frame 3 comes to be suspended from the instrument body 1 via the stiff spring 4.

After this, as in the conventional case, by simply pushing up the frame 3 sufficiently, the legs 7 will elastically expand, and the frame 3 will rise to the extent that the center part 5 reaches the inside of the spring receiver 8. will be attached to the instrument body 1.

According to such a structure, the engagement between the tight spring 4 and the spring receiver 8 becomes easy, and the installation work becomes simple and convenient, but as can be understood from the above explanation, the frame 3 is If you want to hang it up, you have to push it up until the tip 9 of the stiff spring 4 engages with the upper edge of the spring receiver 8 as shown in the figure.

When temporarily suspended in this manner, the distance between the upper edge of the frame 3 and the lower edge 1B of the side wall 1A becomes narrower. Therefore, it is extremely difficult to perform any work by inserting your hand between the cover 2 and the main body 1 of the instrument while it is temporarily suspended.

In order to widen the above-mentioned spacing, it is sufficient to use a spring with sufficiently long legs 7 as the stiff spring 4, but this would not only increase the size of the stiff spring but also shorten the main body of the device to the extent that it can be used. Therefore, it is necessary to use a tall (deep) device, which results in an increase in the size of the device itself.

(Problems to be Solved by the Invention) This invention is a lighting equipment in which a frame supporting a cover is attached to the fixture body by means of a stiff spring connected to the frame. In order to facilitate engagement with the spring receiver fixed to the instrument body, the distance between the upper edge of the frame and the lower end of the side wall of the instrument body during temporary suspension can be adjusted without increasing the length of the spring leg. The purpose is to ensure that it is sufficiently wide.

(Means for solving the problem) This invention consists of a gutter-shaped metal fitting with a U-shaped cross section as a spring holder attached to the main body of the device, and a square spring is attached to the center of the lower end of the spring holder. It is characterized by forming a bottom portion with a cavity into which the legs of the foot are inserted.

(Example) An example of this invention will be described with reference to the drawings. Note that parts given the same reference numerals as in FIG. 6 indicate the same or corresponding parts. According to this idea, the spring receiver 8 is constructed of a U-shaped gutter-like metal fitting, and a bottom part 11 with a hollow space 10 in the center is formed at its lower end.

To engage the tight spring 4 with the spring receiver 8,
First, the legs 7 are shrunk inward against elasticity, and then the tips thereof are inserted into the spring receivers 8 through the spaces 10 of the bottom 11. This insertion operation is extremely easy since the bottom 11 of the spring receiver 8 is located close to the lower end 1B of the instrument body 1 and can be visually observed.

After slightly inserting the tip of the leg 7 into the space 10, when the leg 7 is released, it expands outward due to its elasticity, so that the bent part 9 at the tip of the leg 7 engages with the edge of the space 10. match. This engagement causes the frame 3 to be temporarily suspended. The first one that showed this condition was
FIG. As will be understood,
The distance between the upper end edge of the frame 3 and the lower end of the side wall 1A is ensured to the extent that it is approximately equal to the length of the leg portion 7 of the stiff spring 4.

After that, when the frame 3 is pushed up and the connecting fitting 6 is advanced into the spring receiver 8, the legs 7 elastically expand as shown in FIG. 4 through the process shown in FIG. Engages with the upper edge. As a result, the frame 3 comes to be suspended from the instrument body 1 via the stiff spring 4.

(Effects of the invention) As detailed above, according to this invention, when attaching the cover frame to the main body of the device using a stiff spring, it is possible to maintain the simplicity of this type of attachment work, and also to attach the frame to the bottom of the spring holder. By forming a cavity and engaging the bent part of the leg of the stiff spring with the edge of the cavity, when temporarily suspending the instrument body, the gap between the upper edge of the frame and the lower edge of the side wall of the instrument body can be adjusted. It is now possible to secure a sufficiently wider space than the existing proposal, and even if the spring receiver is installed at the lower edge of the side wall of the device body so that it can be easily seen,
When the frame is installed, the tight springs go into the spring holder, so the spring holder does not get in the way of supporting the frame.
