Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a lighting fixture mounting device suitable for a case where a relatively large and thin decorative cover is installed on a ceiling surface and a lighting fixture is mounted by extending downward from inside the cover. Pertains to.

Conventionally, in ceiling-mounted lighting equipment, particularly heavy chandeliers, etc., an inverted L is attached to the ceiling surface and has a locking hole in a downwardly bent piece provided on both sides. A fixture having a shaped locking piece facing upward is provided on the top of the lighting fixture, and this lighting fixture is attached to the ceiling surface. After the locking piece is locked in the locking hole, the set screw is prevented from falling from the locking piece to the bent piece.
If the above-mentioned decorative cover that covers the entire ceiling mounting part is relatively large and thin, even if the cover can be temporarily held by sliding it downward in advance, it will not be possible to reach the set screw mentioned above. However, it is difficult to use this set screw as a fall prevention means.

The present invention relates to a mounting device that improves such means and allows a lighting fixture to be reliably mounted without fear of falling, and will be described below based on embodiments.

In the drawing, reference numeral 1 denotes a mounting plate having a U-shaped cross section, which is attached to the ceiling surface with screws 2 and 2', and has downward positioning pieces 3 and 3' on the periphery.
Downward threaded rods 4, 4' are provided at both ends. 5
is a mounting fixture, which is attached to the center of the lower surface of the mounting plate 1 by appropriate means such as riveting, and has downwardly bent pieces 6 and 6' on both sides, and these bent pieces have slit-shaped locking pieces. 7 and 7' are provided. Reference numeral 8 designates a fixture to be attached, which has inverted L-shaped locking pieces 9, 9' facing upward, which are locked by inserting into the locking holes 7, 7'. Reference numeral 10 denotes a circular seat plate, which is attached to the lower surface of the fixture 8 by appropriate means, and a center light 11 and radially extending arms 12 are attached to the lower surface. Although not shown, necessary lighting equipment such as a lamp housed in a globe is attached to the ends of these arms. 13 is a decorative cover, and the bottom is a seat plate 1
The inner peripheral edge 15 having a large diameter at the top is fitted into the outer peripheral edge of the mounting plate 1 so as to abut the side edges of the positioning pieces 3 and 3'. be combined. 16, 16' are threaded rods 4,
4' through hole. Thumb screws 17 and 17' are screwed into the lower ends of the threaded rods 4 and 4'.

In the above configuration, the fixture 5 may be configured integrally with the mounting plate 1. That is, a locking hole corresponding to the locking pieces 7, 7' may be provided in the center of each of the positioning pieces 3, 3'. Furthermore, the attached fixture 8
may be configured integrally with the seat plate 10. That is, two inverted L-shaped locking pieces may be cut and raised upward from the center of the seat plate 10.

Next, when assembling the above-mentioned components, the decorative cover 13 is attached to the arm 12 as shown in FIG.
After temporarily holding it on the top surface, the locking pieces 9 and 9' are inserted into the locking holes 7 and 7' to lock them, and then the decorative cover 13 is pushed up and the screw rods 4 and 4' pass through. It is sufficient to pass through the holes 16, 16' and appear at the bottom. At this time, as shown in FIGS. 2 and 3, the seat plate 10 is fitted into the inner peripheral stepped portion 14,
The inner peripheral edge 15 is fitted to the outer peripheral edge of the mounting plate 1 and comes into contact with the side edges of the positioning pieces 3, 3'. Next, the thumbscrews 17, 17' are screwed onto the tips of the threaded rods 4, 4' to complete the process.

With the above configuration, the present invention has the following effects.

(1) Since the inner peripheral edge 15 of the decorative cover 13 is positioned so that it can hardly move by the positioning pieces 3 and 3' provided on the mounting plate 1, the threaded rod 4,
Since lateral force is hardly applied to the threaded rods 4', damage to the threaded rods 4, 4', especially the fixed portions at the bases, can be prevented from coming off, and there is no fear of the decorative cover 13 falling.

(2) Since the seat plate 10 is fitted to the inner circumferential stepped portion 14 of the decorative cover 13, it is possible to prevent the seat plate 10 from wobbling, and the locking plates 9, 9' and the locking pieces 7, 7 Since it is possible to reliably prevent the locking action of ' from becoming disengaged, there is no risk of the lighting fixture falling.

(3) The thumbscrews 17 and 17' allow the installation tool to be easily installed from below, and the installation work can be carried out safely without the need for difficult work such as inserting one's hand into a narrow space.
