Description

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

In order to close the open lower surface of the luminaire body with a translucent panel, a panel frame is attached to the panel, and this panel frame is removably installed on the open lower surface of the luminaire body. I have to. The panel frame is made removable from the appliance body for inspection inside the appliance body, lamp replacement, etc. That is, by simply pulling down the panel frame, it will descend to a predetermined position and be removed from the instrument body at that position.

By the way, in the past, it was common to use a V-shaped spring to install such a panel frame onto the main body of the device. The central winding part of this tight spring is connected to the panel frame via a connecting metal fitting, and a receiving metal fitting into which the legs of the tight spring are slidably engaged is installed on the main body of the device, and the panel frame that has further risen is stopped at a fixed position. It is constructed by fixing a contact piece to the instrument body. According to this, when the panel frame is pulled down, it will descend until the tips of the legs of the stiff springs engage with the brackets, and when raised from the lowered position, a lifting force will be applied by the elasticity acting on the legs of the stiff springs. and rises until it hits the hit piece. Due to this lifting force, it is fixed at the raised position.

However, a support device with such a configuration requires not only the stiff spring but also the above-mentioned connecting metal fittings, receiving metal fittings, contact pieces, etc., which not only increases the number of parts but also requires a long time for the movement of the stiff spring to move up and down. However, the instrument body must be made deeper (higher), which increases the size of the instrument body. Furthermore, since no lowering parts or the like are exposed on the outer surface of the panel frame, a person handling the device for the first time may not know how to lower the cover frame, which is extremely inconvenient.

The purpose of this invention is to simplify the structure for fixing a panel frame attached to a panel to an instrument body.

An embodiment of this invention will be described with reference to the drawings. Reference numeral 1 denotes a panel frame whose peripheral edge is U-shaped in cross section, to which a translucent panel 2 is appropriately attached. Reference numeral 3 denotes the main body of the apparatus, and the example shown in the figure shows an embedded type, which is installed so as to be embedded in the ceiling 4 or the like. As mentioned above, the panel frame 1 is removably installed with respect to the appliance body 3, but in this invention, the support fittings 7 as shown in the figure are parallel to the side wall 1A of the panel frame 1, and the side wall 1A and the appliance It is arranged in a gap between the main body 3 and the side wall 3A. It is supported by a shaft 5 passing through the side wall 1A so as to be rotatable about the shaft 5. For this purpose, a hole 8 is provided through which the shaft 5 passes. Further, an engaging portion 6 such as a rotating roller is provided at a fixed position on the side wall 3A of the instrument body 3, and a key portion 9 that engages with the engaging portion 6 is connected to the end of the support fitting 7 on the opposite side from the hole 8. It is formed into an L-shape. The key part 9 has an arcuate inner side to facilitate engagement with the engaging part 6. Further, the support fitting 7 has a claw piece 10 that stands up at a location away from the hole 8.

1 and 2 show a state in which the support metal fitting 7 supports the panel frame 1. In this state, the key portion 9 engages with the engaging portion 6, and this engagement causes the support metal fitting 7 to The panel frame 1 is prevented from falling from the instrument body 3 via the panel frame 1.

To remove the panel frame 1 that is supported in the raised position as described above, hold the claw piece 10 and pull down the support fitting 7 and rotate it around the shaft 5 (in FIG. 5 in the clockwise direction), and if the key part 9 is separated from the engaging part 6 by this rotation, then the panel frame 1
Just pull it down. FIG. 3 shows a state in which the support fitting 7 has been rotated approximately 90 degrees from the state shown in FIG.

In order to install the removed panel frame 1 in the instrument body 3, the panel frame 1 is first inserted into the instrument body 3, and the support fittings 7 are simply rotated in the opposite direction to the previous direction. When this is rotated to the position shown in FIG. 2, the key portion 9 engages with the engaging portion 6 to prevent further rotation and prevent the support fitting 7 from being reversed.

Note that the support fittings 7 may be installed at a plurality of locations along one side edge of the panel frame 1. Alternatively, the panel frame 1 may be installed along the opposite side edges, but as shown in FIG.
1 may be fixed to the side wall 3A. In this case, to attach the panel frame 1, first attach one side edge of the panel frame 1 to the claw piece 11 of the bracket 12.
Insert the panel frame 1 into the instrument main body 3 at an angle so that the panel frame 1 rests on the instrument body 3, then raise the other side edge as described above, rotate the support fitting 7, and insert the key part 9 into the engagement part 6. engage. It will be easily understood that the panel frame 1 can be removed by performing the opposite operation.

As detailed above, according to this invention, a support metal fitting is used instead of the conventional hard spring, so the number of parts used is reduced, and there is no need to manufacture the instrument body deeply. At the same time, all of the support fittings except for the claws are located in the gap between the side wall of the panel frame and the side wall of the appliance body, and are almost invisible from the outside.
It does not spoil the appearance, and since the claw pieces are exposed at the bottom end of the panel frame, it is easy to understand at a glance that the support metal fittings can be pulled down using the claw pieces.
