Description

[Detailed description of the invention] This invention relates to ceiling-mounted lighting equipment.
The purpose is to easily and reliably install lighting equipment on the ceiling.

Generally, in the case of lighting equipment that is mounted on the ceiling, the support metal fittings installed on the lighting equipment to support its weight are locked to the mounting metal fittings attached to the ceiling, and these support metal fittings and the mounting metal fittings are covered by attaching a canopy. . In this case, it was necessary to both be able to easily attach the canopy and to be able to reliably lock the support fittings to the mounting fittings.

The present invention has been made in view of the above points, and will be explained below based on FIGS. 1 and 2.

1 and 2 show an embodiment of the present invention, 1
is a hanging rosette fixed to the ceiling, and mounting brackets 3 having L-shaped locking pieces 2 projecting from both sides are attached to the ceiling around the hanging rosette. 4 is multiple lighting equipment 5
(Only one of them is shown in FIG. 1 and the others are omitted) is a nearly cylindrical device body with a bottom at the upper end attached via a support 16, and a caulking portion 17 protruding from the center of the upper surface is attached to the supporting metal fitting 6. The inside of the caulking part 17 of the instrument main body 4, into which the support metal fitting 6 is inserted, is a power wire insertion hole 18. A pair of arm portions 8 are extended obliquely upward from both sides of the bottom portion 7 of the support fitting 6 in a manner that widens the distance from each other and extends toward the end, and an outward horizontal locking portion 9 is provided at the upper end of each arm portion 8. A locking hole 13 is formed near the tip of the arm portion 8 and in the locking portion 9, respectively. The support fitting 6 is locked to the mounting fitting 3 by inserting the locking piece 2 into the locking hole 13 and placing the locking portion 9 on the horizontal portion of the locking piece 2. At the tip of the locking part 9, an L-shaped screw mounting piece 14 is bent and extended downward, and the mounting screw 10
is provided on the horizontal portion of the mounting piece 14 to protrude downward.
Reference numeral 11 denotes a canopy which is fitted onto the upper end of the instrument main body 4 so as to be movable up and down, and is prevented from coming off from the instrument main body 4 by a support metal fitting 6 and a strut 16. drilled,
A cap nut 12 is screwed onto the mounting screw 10 inserted through the insertion hole 15 from below, and is mounted so as to cover the mounting fitting 3 and the support fitting 6 and abut against the ceiling at the upper end. A power line 19 is connected to the hook rosette 1 through a hook sealing cap 20 attached to its tip, and is inserted through the power line insertion hole 18 and connected to electrical components such as a switch inside the instrument body 4.

However, this ceiling-mounted lighting fixture is installed in the following manner. Remove the cap nut 12 from the mounting screw 10 and move the canopy 11 toward the lower end of the instrument body 4 to expose the support fitting 6.
3 is inserted into the locking hole 13 of the locking portion 9 from the bottom surface of the locking portion 9, and the locking portion 9 is inserted into the locking hole 13 of the locking portion 9.
The supporting metal fitting 6 is placed on the horizontal portion of the mounting metal fitting 3, and the supporting metal fitting 6 is locked to the mounting metal fitting 3. Next, the canopy 11 is attached to the instrument body 4.
Push up to the upper end side and insert the insertion hole 15 of the canopy 11.
When the mounting screw 10 of the support metal fitting 6 is inserted into the canopy 11 and the cap nut 12 is screwed onto the mounting screw 10 from below, the canopy 11 is mounted so as to cover the mounting metal fitting 3 and the support metal fitting 6 and come into contact with the ceiling at the upper end. Finally, the fixture body 4 rotatably supported by the support fitting 6 is rotated to adapt the direction of the lamp 5 to the room.

In this way, the ceiling-mounted lighting fixture according to the present invention has a mounting screw protruding downward from the arm of the support fitting that is engaged with the locking piece in the locking hole near the top end, and the canopy is compatible with the mounting screw. Insert the mounting screw into the insertion hole that was drilled and secure it with a nut, and install the canopy with the upper end of the canopy in contact with the ceiling. This has the effect that the mutual positions of the canopy are uniquely regulated, the support fitting does not fall off from the locking piece, and the canopy can be easily attached to the attachment screw.
