Description

[Detailed Description of the Invention] This invention relates to a direct-ceiling mounting device for lighting equipment.

As shown in FIG. 1, when the lighting fixture 1 is directly attached to the ceiling 2, generally the fixture body 3 is attached as shown in FIG. 2 or 3.
Attach it to the ceiling 2 with wood screws 4 or bolts 5, and attach the lamp 6, ballast 7, mounting bracket 8,
Attach the glove 9.

Therefore, this direct attachment to the ceiling requires work at a high place and is not easy to install.

Furthermore, when the ceiling is made of concrete, a box 10 is usually embedded in the ceiling during construction, as shown in FIGS.
', so as shown in Fig. 7 or 8, the lighting equipment A,
Hanging B (Limited to the so-called hanging type, requiring additional construction if directly attached.

Therefore, an object of this invention is to provide a direct-ceiling mounting device for lighting equipment that allows lighting equipment to be easily mounted directly on the ceiling using a hook-shaped recessed rosette.

The 9th direct-mounted lighting fixture to which the first embodiment of this invention is applied
, shown in Figure 10.

That is, this lighting fixture has a central part 14 of the fixture body 14.
A is squeezed out, and an insertion hole 15 similar to the embedded rosette 10' is formed in the center thereof, and a lamp socket 16, a ballast 17, a switch 18, and a cover 1 are inserted into the device body 14.
9. Parts such as the hook ceiling 20 are attached, and the lamp P is attached to the lamp socket 16.

On the other hand, the ceiling fixture includes, as shown in FIGS. 11 to 13, an inverted hat-shaped tensioning fitting 21, a U-shaped hooking fitting 24 having a hooking hole 22 for hooking ears and a protruding hole 23, The central piece 21 of the tension fitting 21 consists of an operating thumbscrew 25.
By forming a screw insertion hole 26 in a, passing the thumbscrew 25 from below, passing the coil spring 27 through the screw 25, and further forming a screw hole 28 in the lower piece of the hook 24 and screwing the screw 25. It is formed.

Figures 14 and 15 show the order in which the lighting fixtures are installed.

That is, the embedded rosette 10' is inserted into the insertion hole 15 of the instrument body 14, and rotated slightly to temporarily fix the instrument body 14 to the hooking lug 10a (FIG. 14).

Next, hook the hole 22 of the hooking fitting 24 of the fixture into the hooking ear 10a.
, and its tip protrudes from the protrusion hole 23.

Further, when the thumbscrew 25 is turned in the screwing direction, the knob head 25a moves upward, and the tension fitting 21 supported by the knob head 25a is pushed up.
b comes into contact with the lower surface of the appliance main body 14 and pushes it up, bringing it into pressure contact with the ceiling 2 (FIG. 15).

In this way, the appliance main body 14 is fixed to the ceiling 2.

On the other hand, when removing it from the ceiling, turn the thumbscrew 25 in the opposite direction to remove the hook fitting 24 from the hook lug 10a.

With this structure, the fixing metal fitting can be fixed by hand by turning the shadow thumbscrew 25 to the hooking ear 10a while the main body 14 is temporarily fixed, and installation is easy even when working at heights. become.

Additionally, you can attach the fixtures in any direction depending on the style of the room.

As mentioned above, the direct ceiling mounting device for lighting equipment of this invention is
The main body of the device is temporarily held on the hooking ears of the rosette, each hooking metal fitting is hooked on the hooking ear, and the main body of the device is fixed to the ceiling by pressure using a tension fitting via a thumbscrew, making the work easy and safe. Since it is not connected to the metal fittings, no connecting means is required, and the direction of the device can be freely set.

Furthermore, there is no need to provide screw holes in the hook ears, and there is no need to screw together on the ceiling.Furthermore, since the fixtures are individually hooked to the hook ears, the work of hooking the hook metal fittings is safe and easy. Since it is not a push screw, it has the advantage that buckling does not occur.
