Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting device for a ceiling-mounted lighting fixture which is mounted on a ceiling rosette installed on the ceiling.

[0002]

2. Description of the Related Art Generally, a ceiling rosette is installed as a power supply port on the ceiling of a house or the like, but the above-mentioned lighting fixture is relatively large for mounting a ceiling-mounted lighting fixture, so it is directly locked to the ceiling rosette. In addition to avoiding the above, it is a difficult task to screw and fix to the ceiling surface while supporting heavy lighting equipment.Therefore, separately from the ceiling rosette, the mounting bracket is fixed by screwing, and the lighting fixture is mounted on the mounting bracket. The main body of the fixture is rotated and locked, or the lighting fixture is partially locked by fixing with screws and then electrically connected.

[0003]

In the above prior art, not only is it difficult to screw the tool toward the ceiling when mounting the lighting fixture, but also the heavy lighting fixture is fixed at a fixed position on the ceiling during the above work. Since it has to be held in place, it is not easy for a worker who is accustomed to the installation work to install it by himself.

According to the present invention, the lighting fixture can be installed by simply lifting the lighting fixture to the ceiling without using the tool toward the ceiling, and can be removed by simply pressing the lock release button. The purpose is to obtain a mounting device.

[0005]

[Means for Solving the Problems] The above object is to provide a locking claw for locking and connecting to the ceiling rosette in a ceiling direct mounting type lighting fixture mounting device to be mounted on a ceiling rosette installed on the ceiling. And a plug receptacle electrically connected to the lighting fixture, and when inserted through the locking hole provided in the lighting fixture, elastically protrudes laterally and locks in the locking hole to reduce the load of the lighting fixture. This is accomplished by providing a plurality of lock projections that can be supported and a lock release button that retracts the lock projections against elasticity.

[0006]

A ceiling-mounted lighting fixture mounting apparatus according to the present invention comprises a locking claw that can be locked to a ceiling rosette for electrical connection, and a plug receiver electrically connected to the locking claw. Has a mouth and. Insert and lock the above locking claws into the locking groove of the ceiling rosette installed on the ceiling,
Secure the mounting device. Next, when the ceiling-mounted luminaire is lifted and the locking hole provided in the approximate center of the luminaire bottom plate is inserted into the mounting device, a plurality of locking protrusions projecting to the side surface of the mounting device at the edges of the locking holes. The protrusion is inserted while retracting it against the elastic force of the spring incorporated inside the locking protrusion. When the edge of the locking hole has finished passing through the locking projection, the locking projection returns to the old and protrudes, and the lighting fixture is fixed by locking the edge of the locking hole. At the same time,
The plug for connecting the power source, which is provided so as to project from the upper portion of the lighting fixture, is inserted into the plug receptacle of the mounting device, and the electrical connection is also completed.

When removing the lighting fixture, the locking release button provided on the mounting device is pushed up to retract the locking projection that locks the lighting fixture against elasticity. Therefore, the locked state of the lighting fixture is released, and the lighting fixture can be removed by its own weight.

In FIG. 1, reference numeral 1 denotes an example of a mounting device for a ceiling-mounted lighting fixture, which is locked to a ceiling rosette 17 installed on the ceiling to hold the mounting device 1 and electrically connect it. Has a locking claw 2 and a plug receiving port 10 electrically connected to the locking claw 2, and the edge of a locking hole 15a provided in the fixture body 15 of the lighting device by moving forward and backward by elasticity. And a plurality of locking projections 3 for locking the locking projections 3 and a locking release button 5 for retracting the locking projections 3 to unlock the locked state of the instrument body 15. In addition, 1a is a notch 15c for positioning when the instrument body 15 is inserted.
Is a ridge corresponding to. As shown in the top view of FIG. 2 and the cross-sectional views of FIGS. 3 and 4, the mounting device 1 is a plug in which locking claws 2 for locking a sealing rosette are mounted facing each other on the upper surface and are mounted via metal fittings 11. An electric wire 9 is electrically connected to the receptacle 10. Inside the mounting device 1, the locking hole 15 of the fixture body 15 of the lighting fixture is provided.
In order to lock the edge of a, a plurality of locking projections 3 that move forward and backward while sliding, and an elastic spring 4 that constantly pushes the locking projections 3 outward are housed and Each has a gap for smooth sliding. The locking projection 3 has an inclined surface on which the edge of the locking hole 15a slides when the device body 15 is inserted into the protruding portion, and the slide pin 5a provided inside the locking release button 5 is inclined. A slot 3a having an inclined surface that abuts the surface and slides, and a protrusion 3b for preventing the spring 4 from coming off due to the reaction force are provided. The locking projection 3 and the spring 4 are formed by the slide pin 5a of the locking release button 5.
The disk-shaped metal fitting 7 having a square hole through which is inserted is attached by screws 14.

The lock release button 5 is provided with a flange 5b together with the slide pin 5a, and the flange 5b is provided.
Is attached by a cover 6 fixed with screws 13, but the flange 5b can be moved vertically along the inside of the cover 6. On the side wall of the mounting device 1,
