[Detailed description of the device]

[0001]

[Field of Industrial Application] This invention is applied to lighting equipment.
The present invention relates to an improvement of a device that holds a frame that is supported by a fixed plate and is attachable.

[0002]

2. Description of the Related Art Conventionally, in a lighting apparatus, an apparatus for holding a frame which is supported by a fixing plate which is fixed to a ceiling or the like and which can be attached is provided with a holding portion at a central portion of an elastic rod-like body. A kick spring having locking parts provided at both ends thereof is used, and the kick spring is attached to the spring receiver provided on the fixing plate with the holding part of the kick spring as the center. When attaching the frame, the holding portion of the kick spring is pulled downward, so that the holding portion moves downward while squeezing the kick spring that is a rod-shaped body along the spring receiver, and the frame is externally attached to the holding portion. By supporting and further pushing up the frame upward, the kick spring narrowed by the spring receiver expands due to its elasticity, and the frame supported by the holding portion of the kick spring is expanded. Write the pulling, it is generally made by integrally attached to the fixed plate of the luminaire.

[0003]

However, in the above-mentioned conventional apparatus, when a kick spring is used to attach the frame to the fixing plate of the lighting fixture, the weight of the frame attached to the fixing plate of the lighting fixture is all attached to the spring receiver. Although it is supported by the kick spring, the strength of the kick spring is limited, and when attaching a heavy frame to the fixing plate of the lighting fixture, it is not possible to fully expect the frame to be pulled up by the elasticity of the kick spring, In addition, if the elasticity of the kick spring is to be secured against heavy weight, the rigidity of the kick spring becomes strong, making it extremely difficult to pull down the kick spring by human force when mounting the frame, and the elasticity itself is impaired due to the weight load on the kick spring itself. There is a drawback that it is easily damaged.

The kick spring is squeezed when pulled down along a spring receiver to which the kick spring is attached, and is expanded laterally when pulled up. When the kick spring is pulled down by human power or pulled up and expanded by utilizing elasticity. ,
If the kick spring is pulled down or pulled up in the wrong direction, the kick spring has a drawback that it is easily detached from the spring receiver.

Further, when the frame is attached to or removed from the fixing plate, the kick spring itself is housed in the lighting fixture, which makes it difficult to attach and detach the frame, resulting in a marked decrease in workability. There is a fear.

[0006] Therefore, this invention is to improve the drawbacks of the above-mentioned conventional ones, and easily and firmly secures the mounting strength of the frame and improves the workability in mounting the frame to the fixing plate of the lighting fixture. It is the one to try.

[0007]

To this end, a support metal fitting having a support hole at its tip which can be attached to a detachable metal fitting attached to the peripheral edge of the frame of the lighting fixture, and the above-mentioned support provided in the fixing plate are provided.
One end slides along a long hole extending at right angles to the moving direction of the holding metal fitting, the above end portion is connected via a coil spring, and the other end is rotatably pivotally attached by one pin by a movable metal fitting. The tip is rotatably connected.

[0008]

With the above-mentioned structure, when connecting the fixing plate for fixing the frame constituting the lighting fixture to the ceiling or the like,
First, when the support metal fittings rotatably supported by both movable metal fittings are pulled vertically downward, the movable metal fittings are initially fixed to the fixed plate in the direction of extending the coil spring, that is, in the direction opposite to the contracting direction of the coil spring. Along the long hole that extends in the left-right direction
Although it is guided and slides, when the support fitting falls below the horizontal position of the long hole of the fixed plate, the coil spring contracts and the movable fitting starts sliding in the same direction as the contraction direction.
Since the ends of the two movable fittings slide toward each other due to the contracting force of the coil spring, the supporting fitting extends downward while the operation is lightened by the contracting force of the coil spring. The frame can be easily attached to the support hole formed in the.

Next, after the frame is attached to the support fitting, the ends of the two movable fittings supporting the support fitting are pushed upward together with the frame so that the ends of the two movable fittings resist the contraction force of the coil spring. The coil springs that have been contracted are extended by sliding them along the long holes in a direction away from each other and pulling up the support fittings, but since the coil springs are always elastic in the contraction direction, When the support metal fitting is pushed up beyond the horizontal position of the slot, the end of the movable bracket slides in the slot again in the same direction as the coil spring contraction direction. Moreover, the frame can be reliably fixed to the fixing plate.

In the state where the frame is attached to the fixed plate,
Since the weight of the frame is applied to one end for fixing the movable fitting to the long hole of the fixed plate, the load on the coil spring is lessened, and the deterioration of the coil spring due to long-term use can be prevented.
