Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a device for attaching a lighting fixture to a ceiling.

BACKGROUND ART In a conventional lighting fixture mounting device, the main body is mounted on the ceiling via a mounting adapter, and a cover is provided around the mounting adapter.

Problems to be Solved by the Invention The above mounting device requires a separate cover to cover the mounting adapter, which increases costs.

The present invention aims to reduce costs by providing a mounting device in which the mounting adapter itself also serves as a cover, and also provides a device that allows the main body to be easily attached to and removed from the mounting adapter.

Means for Solving the Problems The present invention includes a cylindrical mounting adapter that is attached to the ceiling and has a locking hole on the side, and a locking portion that is biased outward so as to be locked in the locking hole. a main body provided on the upper surface, an intermediate portion penetrated through the main body, an upper end having an orthogonal conversion portion for displacing the locking portion inwardly by upward movement, and an operating portion at the lower end exposed on the lower surface of the main body. 1 is a lighting fixture mounting device characterized by comprising a lock release member.

Function According to the present invention, the mounting adapter supports the main body and also serves as a cover, which covers the locking part provided on the top surface of the main body to improve the appearance, and when the main body is attached to the mounting adapter. , just push up the main body from below the mounting adapter,
Further, in order to remove the main body from the mounting adapter, it is only necessary to push up the operation part and release the locking between the locking part and the locking hole, which is a simple attachment/detachment operation.

Example Embodiments of the present invention will be described with reference to the drawings.

Ceiling 1 has hanging ceiling body 2 and mounting plate 3
are fixed in advance. The cylindrical mounting adapter 4 is mounted on the ceiling 1 by, for example, screwing screws 5 into the mounting plate 3, and has a locking hole 6 on the side surface. A locking portion 8 is provided on the top surface of the disc-shaped main body 7.
is urged outward by a spring 9 and covered with a case 11 attached with screws 10. Then, the locking portion 8 is locked by entering into the locking hole 6. The unlocking member 12 is surrounded by a spring 13.
The intermediate portion wrapped with
is exposed on the bottom surface of the main body 7. To explain in more detail, the upper surface of the tip of the locking part 8 has a slope shape,
The spring 9 is wound around a pin 16 at the rear end, so that the pin 16 partially protrudes from the rear end of the case 11, and a convex portion 17 on the intermediate upper surface of the locking portion 8 protrudes from a long hole 18 of the case 11. The orthogonal conversion part 14 of the locking release member 12 passes through the locking part 8, and the uppermost end projects from the hole 19 of the case 11, and a retaining pin 20 is attached to that part. The intermediate side surface of the mounting adapter 4 has a stepped portion 21 that spreads outward, and has a reflective surface 22 that extends from the end thereof along the side surface of the main body 7 and then widens outward, and has a reflective surface 22 that extends outwardly from the end thereof. A well-known glove fitting 23 is provided to attach a glove 24. A cord 25 and a hanging ceiling cap 26 are led out from the upper surface of the main body 7, and an annular fluorescent lamp 28 is held on the lower surface of the main body 7 via a support spring 27.

According to the above structure, in order to attach the main body 7 to the mounting adapter 4, the hook sealing cap 26 is coupled to the hook sealing body 2, and then the main body 7 is pushed up from the lower surface of the mounting adapter 4. At this time, the locking part 8 comes into contact with the inner surface of the mounting adapter 4 and is displaced inwardly, and when the main body 7 is further pushed up, the locking part 8 fits into the locking hole 6, and the main body 7 is installed. Attached to adapter 4. Further, in order to remove the main body 7 from the mounting adapter 4, push up the operating section 15. At this time, the orthogonal transformation section 14 displaces the locking part 8 inward, so that the locking part 8 is released from the locking hole 6, and can be removed by lowering the main body 7.

As described above, according to this embodiment, the main body 7 and the attachment adapter 4 can be easily attached and detached, and the attachment adapter 4 covers the locking mechanism portion on the upper surface of the main body 7, improving the appearance.

In addition to providing the locking hole 6 directly on the mounting adapter 4, a plate material with a hole equivalent to the locking hole 6 may be fixed to the mounting adapter 4 on the inner surface of the mounting adapter 4. , the hole may be approximately U-shaped with an open upper edge.

Effects of the Invention According to the present invention, the main body can be easily attached and detached from the mounting adapter, and the mounting adapter covers the locking mechanism portion on the upper surface of the main body, thereby improving the appearance.
