Description

[Detailed Description of the Invention] The present invention relates to a lighting fixture, and its purpose is to reduce the shaking of a cord-suspended lighting fixture.

In general, a cord-hanging type lighting fixture has a lighting fixture 1 connected to a ceiling hook 4 provided on a ceiling 3 through a ceiling hook 2 provided at the upper end, and suspended by a power line 5, as shown in Fig. 1. It is a lighting fixture that has been installed.

However, in such a device, the lamp 1 is only suspended by the power line 5, and the lamp 1 swings even when the wind blows, which is inconvenient for use.

The present invention has been developed in view of the above points, and will be explained below based on the drawings.

2 to 4 show an embodiment of the present invention, in which a cylindrical lower flange 6 and a truncated conical cylindrical upper flange 7 movably fitted onto the lower flange 6 are connected to the lamp 1.
It is interposed between the back surface of the ceiling 3 and the ceiling 3. The lower flange 6 has a hollow cylindrical shape and has an inner flange 8 at the lower end, and is attached to the back surface of the lamp 1 with screws 9, through which the power line 5 drawn out from the center of the lamp 1 is inserted. On the other hand, the upper flange 7 is a hollow truncated cone-shaped cylindrical body with a small diameter hole at the lower end, and is fitted onto the outer periphery of the lower flange 6 by its elastic force, although it can move vertically. The interval between the ribs 12 is set to be approximately equal to the width of the hook sealing receiver 4.

However, the upper flange 7 is moved toward the lamp 1 side so that the lower flange 6 is accommodated therein, that is, the height of the upper flange 7 and the lower flange 6 is lowered, and in this state, the power supply inserted through each line 5
Connect and lock the hook ceiling 2 at the tip of the hook ceiling holder 4 provided on the ceiling 3, and then move the upper flange 7 upward to cover the hook ceiling 2 and the hook ceiling receiver 4, and bring the upper end into contact with the ceiling 3. , is fitted onto the outer periphery of the hook ceiling 2 and the hook ceiling receiver 4 using the ribs 12 on the inner circumference.

The present invention is constructed as described above, and a cylindrical lower flange 6 is attached to the back of the lamp 1 which is suspended from the ceiling 3 by a power line 5, and an upper flange 7 having a rib 12 on the inner circumference is attached to the lower flange 6. A power line 5 is inserted into the upper flange 7 and the lower flange 6 so as to be movable in the vertical direction, and a hook ceiling 2 provided at the upper end of the power line 5 is attached to a hook ceiling receiver 4 provided on the ceiling 3. By connecting and locking the lamp 1 to the power line 5 and suspending the lamp 1 by the power line 5, the upper end of the upper flange 7 is in contact with the ceiling 3 and the hook ceiling 2 and the hook ceiling receiver 4 are fitted between the ribs 12. Lighting equipment 1
is stretched between the lamp 1 and the ceiling 2 by an upper flange 7 and a lower flange 6 that surround the power line 5, and the impact force is absorbed by the fitting force between the two, thereby suppressing the shaking of the lamp 1. Further, the upper flange 7 is fitted into the hook ceiling 2 and the hook ceiling receiver 4,
This prevents the two from rotating to release each other and prevents them from coming out of the locked state and falling.
