Description

[Detailed Description of the Invention] This invention relates to a panel frame support device for lighting equipment.

In lighting equipment, it is common practice to support a translucent panel by a panel frame, and to install this panel frame on the main body of the equipment. In this case, the panel frame must be removable relative to the appliance body, as is necessary, for example, when replacing the lamp.

The purpose of this invention is to simplify the structure by making it possible to attach and detach the panel frame to and from the appliance body using common metal fittings.

An embodiment of this invention will be described with reference to the drawings. Reference numeral 1 denotes the instrument body, 2 a translucent panel, and 3 a panel frame that integrally holds the periphery of the panel 2. The panel frame 3 closes the opening of the instrument body 1 in an openable and closable manner. According to this invention, at least two metal fittings 4, which serve both as fixing and hooking to the panel frame 3, are fixed to one side edge of the panel frame 3. The metal fitting 4 includes a metal fitting main body 5, a connecting portion 6 that is connected to the metal fitting main body 5, has a width narrower than the metal fitting main body 5, and is bent in an L shape, and a hook portion 7 that continues to the metal fitting body 5 and has a width wider than the connecting portion 6. It is mainly composed of.

On the other hand, a hole 1 in the peripheral edge 11 of the instrument body 1 is large enough to allow the fitting body 5 and the hook 7 of the fitting 4 to pass through.
2, and a hole 1 that is continuous with this below and has a size that allows the connecting part 6 to pass through but not the hook part 7.
A hole 14 consisting of 3 is formed. Note that the tip of the peripheral edge portion 11 is appropriately bent, and is fixed to a ceiling or the like using an upright wall 15 at the tip.

1 and 2 show a fixed state of the panel frame 3. In this state, the metal fitting 4 is inserted into the hole 14, and the metal fitting main body 5 rests on the lower edge of the hole 12. Here, in order to drive the panel frame 3 to open the lower surface of the instrument main body 1, first move the panel frame 3 to the peripheral edge 11.
Move it away from it. As a result, the metal fitting body 5 is removed from the hole 12, and the connecting portion 6 is removed from the hole 13.
It will reach above. Now, drop the panel frame 3 slightly downward. Then, as shown in FIG. 4, the connecting portion 6 falls into the hole 13. In this state, since the hook portion 7 is wider than the hole 13, the metal fitting 4 will not slip out from the hole 14.

Then, the panel frame 3 is rotated around the area where the hook 7 and the hole 13 engage, or in other words, around the side edge of the panel frame 3 to which the metal fitting 4 is fixed. The panel frame 3 is rotated with the hook portion 7 engaged with the side periphery of the hole portion 13 as shown in FIG. 5. In this state, the panel frame 3 becomes almost vertical and hangs from the instrument body 1. However, it does not fall away from the instrument body 1.

Note that this rotation operation is performed after dropping the connecting part 6 into the hole 13 as shown in FIG. 4, so that a large space is formed between the hook part 7 and the upper edge of the hole 14. become. Therefore, there is no need to slide the hook part 7 until it comes into close contact with the peripheral edge 11 of the instrument main body 1, and the panel frame 3 can be rotated smoothly.

FIG. 6 schematically shows the above operation.
A corresponds to FIG. 1, C corresponds to FIG. 4, and D corresponds to FIG. 5. In order to attach the panel frame 3 that has been opened once to the instrument body, it is sufficient to perform the operations in the completely reverse order of the previous operations. In addition, the side edge of the panel frame 3 opposite to the side edge to which the metal fittings 4 are attached is also supported by the instrument body 1, and at this time, a support metal fitting that does not interfere with the movement of the panel frame 3 during the above-mentioned operation is used. be used. For example, as shown in the specification and drawings of Utility Model Application No. 130072/1983, a claw piece is provided on a metal fitting rotatably attached to the main body of the device, and the lower surface of the side edge of the panel frame is supported from below by this claw piece. Just do it like this. In this case, when rotating the panel frame, the metal fittings may be rotated to move the claw pieces from the lower surface of the side edge of the panel frame.
Of course, the metal fittings are not limited to such metal fittings, and metal fittings having an appropriate shape may be used.

As detailed above, according to this invention, the support of the panel frame to the main body of the instrument and the hooking during rotation are made possible by the use of a single metal fitting, which makes the structure for fixing and removing the panel frame easier. This has the effect that it can be simplified.
