Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling-mounted lighting fixture for mounting work by fixing a mounting bracket connected to a lamp to a mounting plate mounted on the ceiling.

[0002]

2. Description of the Related Art A luminaire which is mounted by covering a mounting plate fixed to a ceiling with a mounting bracket connected to a lamp and fixing the mounting plate generally has a heavy weight or a luminaire including a lamp. Due to their large shape, it is often difficult to carry out the mounting work while supporting the lamp at a high place. Therefore, first of all, a mounting plate having a small shape and being light and easy to handle is fixed to the ceiling, and usually a plurality of long screws are vertically fixed to the mounting plate. Next, mount the lighting fixture by covering the mounting plate with the mounting bracket integrally connected to the lamp and tightening the decorative nuts on the ends of the long screws that penetrated the holes provided in the mounting bracket. Was there.

[0003]

However, since the above-mentioned mounting bracket usually has a rising edge around its periphery, even if this mounting bracket is put on the mounting plate already fixed to the ceiling, the long length fixed to the mounting plate is fixed. It was not easy to project the tip of the screw from the hole of the mounting member, and it was extremely difficult to support a large or heavy lamp body near the ceiling. It is an object of the present invention to provide a ceiling-mounted lighting fixture having a mounting bracket connected to a lamp body that can be easily mounted on a mounting plate fixed to a ceiling.

[0004]

The above object is to cover a mounting plate having a plurality of long screws fixed vertically with a mounting bracket having a rising peripheral edge which is connected at a distance from the lamp body, and to provide a hole for the mounting bracket. In a ceiling-mounted lighting fixture in which a lamp body connected to the mounting bracket is screwed to the long screw penetrating through, the at least one rising protrusion along the outer periphery of the mounting plate is provided, and This can be achieved by providing a concave portion on the peripheral edge that engages with the rising protrusion.

[0005]

In the ceiling-mounted lighting fixture of the present invention, at least one rising protrusion is provided along the outer periphery of the mounting plate on the mounting plate to which the long screw fixed to the ceiling is fixed, and the mounting plate is attached. The mounting metal fitting connected to the lamp body that is covered and fixed is provided with a recessed portion that engages with the rising protrusion on the periphery. Since these rising protrusions and engaging recessed portions are both provided on the outer periphery of the mounting plate and the peripheral edge of the mounting bracket as described above, engaging the recessed portions with the rising protrusions does not affect the feel of the hand. It can be easily performed by just relying on it, and the engagement state can be visually observed from diagonally below, so that the positions of the through holes of the fittings corresponding to the long screws can be easily determined. It is easy to insert the tip of the into the through hole.

[0006]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is an exploded perspective view showing a mounting base portion in an embodiment of a ceiling-mounted lighting fixture according to the present invention, FIG. 2 is a perspective view showing a state in which a mounting bracket is engaged with a mounting plate of the above embodiment, and FIG. It is an appearance perspective view showing an example of an example.
In FIG. 1, the mounting base of this embodiment comprises a mounting plate 1 fixed to the ceiling and a mounting bracket 4 fixed to the mounting plate 1, and a plurality of long screws 3 are vertically fixed to the mounting plate 1. However, at least one rising protrusion 2 is provided along the outer circumference. In the figure, a screw for fixing the mounting plate 1 to the ceiling and a screw hole used for tightening the screw,
Also, the introduction hole for the power supply line is omitted. Further, the mounting metal fitting 4 has a rising peripheral edge on the periphery thereof, and concave portions 5 which engage with the rising protrusions 2 are provided on the rising peripheral edge respectively corresponding to the rising protrusions 2 and fixed to the mounting plate 1. Through holes 6 are provided corresponding to the positions of the long screws 3, and the fittings 4 are connected to the lamp body of the luminaire with a gap. When mounting the ceiling-mounted lighting fixture of the present invention formed as described above, after fixing the mounting plate 1 to the ceiling surface, the power supply line is guided into the lamp body through the mounting bracket 4, and the mounting bracket is mounted. When the mounting plate 1 is covered with 4 from below, and the rising protrusions 2 provided along the outer periphery of the mounting plate 1 are engaged with the recessed portions 5 provided on the rising peripheral edge of the mounting bracket 4, the mounting plate 1 is attached. The tips of the plurality of fixed long screws 3 can easily pass through the through holes 6 provided corresponding to the mounting fittings 4, respectively. Therefore, when the decorative nuts 7 are respectively tightened on the penetrating portions of the long screws 3 as shown in FIG. 2, the work of attaching the ceiling-mounted lighting fixture to the ceiling is completed as shown in FIG. Since both the rising projection 2 and the recessed portion 5 are provided along the peripheral edges of the mounting plate 1 and the mounting bracket 4, the engagement can be easily performed only by relying on the feel of the hand. ,Also,
It is also possible to perform it while visually confirming it from diagonally below. Therefore, while supporting a heavy and large lamp body for a long time, the tip of the long screw 3 causes the through hole 6 of the mounting bracket 4 to pass.
The mounting bracket 4 can be easily mounted on the mounting plate 1 without performing a difficult work such as searching for.

[0007]

As described above, in the ceiling-mounted lighting fixture according to the present invention, the mounting plate having a plurality of long screws fixed vertically is covered with the mounting bracket having the rising peripheral edge connected to the lighting unit at a distance. In a ceiling-mounted lighting fixture in which a lamp connected to the mounting bracket is screwed to the long screw penetrating the hole of the mounting bracket, at least one rising protrusion along the outer periphery of the mounting plate is provided. By providing a recessed portion that engages with the rising protrusion on the periphery of the mounting bracket, the long screw of the mounting plate can be inserted into the through hole of the mounting bracket only by engaging the recessed portion with the rising protrusion. Since it can be easily inserted, it is possible to easily attach the ceiling-mounted lighting fixture.
