Description

[Detailed Description of the Invention] This invention relates to a panel support device for lighting equipment. 2. Description of the Related Art It is well known that lighting fixtures are box-shaped with an opening at the bottom as a main body for installing or housing a fluorescent lamp, a ballast, etc., and the opening is covered with a translucent panel. In such lighting equipment, the panel needs to be removable when replacing the fluorescent lamp, etc. For this purpose, a panel frame is provided around the outer periphery of the panel, and this panel frame is supported by the elasticity of a V-shaped spring. Therefore, it should be pulled up at all times, and the pulled-up position should be at a position that covers the opening surface of the instrument body. When pulled down against the elasticity of the V-shaped spring, the tip of the leg of the V-shaped spring descends until it catches the engagement fitting, and this lowered position becomes a position where the opening surface of the instrument body is opened. I have to.

FIG. 1 shows an outline of such a lighting fixture, in which 1 is a fixture main body with an open bottom, 2 is a translucent panel, and 3 is a panel frame. In the state shown in the figure, the panel 2 is in a position covering the opening surface of the instrument body 1, and in this state, the panel frame 3 needs to be in a fixed position on the opening surface, so it is usually placed on the side wall of the instrument body 1. The frame 4 provided on the inner surface of 1A is used as a reference plane, and the frame 4 is positioned at a constant distance A from the reference plane. This distance A needs to be maintained even when the panel 2 is pulled down and then pushed up again. Furthermore, when the panel frame 3 is pushed up, the distance B between the side edge of the panel frame 3 and the periphery of the opening surface of the instrument body 1 must also be constant. Particularly in lighting fixtures equipped with air conditioning ducts, this gap is used to absorb indoor air and exhaust it to the outside, so a predetermined gap must be maintained.

On the other hand, as mentioned above, since the panel frame 3 is pulled up in the direction of arrow P by the elasticity of the V-shaped spring, the panel frame 3 is equipped with an engaging fitting that engages with the winding part of the V-shaped spring. There is a need to. Furthermore panel 2
It is necessary to equip the panel frame 3 with a panel presser that presses the panel in the direction of arrow M to prevent it from dancing. The panel presser does not necessarily need to be in contact with the surface of the panel 2, but may be opposed to the surface of the panel 2 with a gap therebetween.

This idea uses a single metal fitting to support the V-shaped spring and hold down the panel so that when the panel frame is pushed up, the distances from the reference frame and the periphery of the device body are set to predetermined values. The purpose is to serve both.

An embodiment of this invention will be described with reference to the drawings. According to this idea, a guide frame 10 as shown in the figure is used. This guide frame 10 is formed by bending both sides of a substrate 11 to form side wall portions 12. And this side wall portion 12
The front surface of the upper end is bent to form a bent edge 13, and an inclined surface 14 is formed from the bent portion of the bent edge 13 to the upper end of the side wall portion 12. 15 is the side wall portion 12
It is the lower edge of An engaging portion 16 bent in an L-shape is provided approximately at the center of the substrate 11, and an engaging hole 17 is formed in this engaging portion 16. The distance between the bent edge 13 and the upper edge 11A of the substrate 11 is set to match the distance A shown in FIG. 18 is a V-shaped spring consisting of a central winding part 19 and a pair of legs 20, and the V-shaped spring 18 is formed by interlinking a metal fitting 21 interlinking with the central winding part 19 with the engagement hole 17. Guide frame 1
Attach to 0. Reference numeral 22 denotes an engaging fitting attached to the inner surface of the side wall 1A, and the base ends of the legs 20 of the V-shaped springs 18 are elastically engaged with both ends of the groove 23 in the center, so that the panel frame 3 can be moved to the lifted position. hold. When the panel frame 3 is pulled down, the bent portion 2 at the tip of the leg 20
0A is pulled down until it engages both ends of the groove 23.
The configuration and operation of the V-shaped spring 18 and the engagement fitting 22 are already well known.

The guide frame 10 is fixed to the panel frame 3 by welding or the like. In this case, the substrate 11 of the guide frame 10 is brought into close contact with the inner surface of the panel frame 3. For this purpose, a notch 3A is provided in the upper wall of the panel frame 3, and the upper edge 1 of the board 11 is
1A is in contact with the inner surface of the upper wall of the panel frame 3,
If the lower end of the substrate 11 is placed on the lower wall of the panel frame 3, the guide frame 10 can be set at the height of the fixed position of the panel frame 3.

When the lowered panel frame 3 is pushed upward, it is pulled upward by the elasticity of the legs 20 of the V-shaped springs 18. At this time, when the front edge 4A of the frame 4 comes into contact with the inclined surface 14 of the guide frame 10, the guide frame 10 and therefore the panel frame 3 are moved from side to side by being guided by this inclined surface 14. The panel frame 3 is then pulled up until the bent edge 13 of the guide frame 10 comes into contact with the bottom surface of the frame 4. Then, the front edge 4A of the frame 4 comes into contact with the base end of the inclined surface 14.

Panel frame 3 pulled upward in this way
Considering this, the distance A between the bent edge 13 and the frame 4 is maintained by abutting them. Furthermore, since the base end of the inclined surface 14 and the front edge 4A of the frame 4 come into contact with each other, the distance B between the panel frame 3 and the periphery of the opening surface of the instrument body 1 is maintained. Furthermore, the lower edge 15 of the side wall portion 12 of the guide frame 3 comes to face the surface of the panel 2, and this serves as a presser for the panel 2. Since the guide frame 10 is provided with an engaging portion 16, it can be engaged with the V-shaped spring 18 using this.

As detailed above, according to this invention, it is possible to position the panel frame 3 in a fixed position, press the panel, and attach the V-shaped spring by simply using one guide frame. .
