Description

[Detailed Description of the Invention] The present invention relates to a lighting fixture mounting device, and its purpose is to easily and reliably mount the lighting fixture to the ceiling.

Generally, lighting fixtures cannot be fixed to ceilings where hanging rosettes are provided, and conventionally, lighting fixtures have been hung from chains or cords. Therefore, the present invention is intended to be able to be firmly and easily attached to the ceiling, and will be explained below based on the drawings.

Figures 1 to 5 show an embodiment of the present invention, in which various lighting parts such as a ballast 2 and a socket 3 are attached to a metal plate main body 1, and a power supply hole 4 is formed in the center. A plurality of so-called daruma holes 7, in which a large-diameter hole 5 and a small-diameter slit-like hole 6 communicate with each other, are bored in the vicinity thereof in parallel in the same direction. On the other hand, the hooking rosette body 8 has a socket 10 for a hooking stopper blade formed on the lower surface of the substantially cylindrical body 9, and a substantially L-shaped hooking claw 11 is bored on the side. The mounting bracket 12 has two screws 1 attached to a bottom piece 13 having a substantially annular plate shape.
4 are screwed together from below, and an upward piece 15 extends from both sides of the bottom piece 13, and a horizontal piece 16 bent outward is formed at the tip of the upward piece 15. An engagement hole 17 is bored in the portion. Reference numeral 26 is a tension box fixed to the back side of the instrument body 1 surrounding the power supply hole 4, and is a substantially trapezoidal cylindrical body having an escape hole 25 for the hooking rosette 8 in the center of its upper surface. Note that 22 is a cover attached to cover the lower surface of the instrument body 1.

However, in order to fix the main body of the device to the ceiling, first insert and engage the mounting bracket 12 into the hook 11 through the engagement hole 17 as shown in Fig. 3, and then attach the main body 1 downward as shown in Fig. Insert the lifting screw 14 through the large diameter hole 5 of the Daruma hole 7, then rotate it to engage the head of the screw 14 in the slit hole 6 and temporarily secure it, as shown in FIG. Tighten and fix it to the mounting bracket 12. In this state, the tension box 26 surrounds the mounting bracket 12 and is clamped between the main body 1 and the ceiling, and the main body 1 is fixed without wobbling. Thereafter, the power line 23 from the instrument main body 1 passes through the hook sealing cap 24 at the tip through the power supply hole 4 of the main body 1 and connects to the hook rosette body 8.

As described above, the present invention provides a hanging rosette body with hooking hooks on the side on the ceiling, and has an engaging hole at the upper end of the upward piece, and a bottom piece that is approximately annular plate-shaped and has a hole in the center that connects the hooking rosette body to the hanging rosette body. Mounting bracket with mounting screws through which the rosette cap passes,
The engagement hole at the upper end engages with the hook of the hook rosette body, and a power supply hole is provided approximately in the center of the main body of the lighting fixture through which the hook ceiling cap connected to the hook rosette body passes, and the above-mentioned mounting is provided around the power supply hole. Corresponding to the mounting screw of the metal fitting, a daruma hole consisting of a large diameter part through which the head of the mounting screw passes and a small diameter part smaller than the head of the mounting screw is provided, and the mounting screw is inserted into the daruma hole to engage the main body. The main body is attached to the ceiling with a cylindrical tension box surrounding the mounting bracket being sandwiched between the ceiling and the main body. The main body can be temporarily fixed by inserting its daruma hole into the mounting screw of the mounting bracket and rotating it. In this state, the gap between the main body and the ceiling is larger than that of the tension box, and the main body can be attached to the mounting screw with a degree of freedom. After that, the main body is temporarily fastened to the mounting screws, so it is easy to tighten the mounting screws without having to hold the main body. The tension box is clamped between the main body and the ceiling, so that the main body is firmly attached to the ceiling without shaking, and the tension box surrounds the mounting bracket, so it has an excellent appearance.

Claims (1)

[Scope of utility model registration request] A hanging rosette body having hooking claws on the side is provided on the ceiling, and a bottom piece having an engagement hole at the upper end of the upward piece and having a substantially annular plate shape and through which a hanging rosette cap connected to the hanging rosette body passes through the central hole. A mounting bracket having a mounting screw is engaged with the hook of the hook rosette body through the engagement hole at the upper end, and a power supply hole is provided approximately in the center of the main body of the lighting equipment through which the hook rosette cap connected to the hook rosette body passes. At the same time, an arc-shaped daruma hole is provided around the power supply hole, which corresponds to the mounting screw of the mounting bracket and consists of a large diameter part through which the head of the mounting screw passes, and a small diameter part smaller in diameter than the head of the mounting screw. After inserting the mounting screw into the daruma hole, rotate the main body to lock the main body to the mounting bracket, and with the mounting screw tightened, insert the cylindrical tension box surrounding the mounting bracket between it and the ceiling. A lighting fixture mounting device characterized in that the main body is mounted on the ceiling by being sandwiched between.
