Description

[Detailed Description of the Invention] The present invention relates to a movable lighting fixture, and its purpose is to freely change the height of the lighting fixture with an extremely simple configuration.

Conventionally, in order to change the height of a lamp, it is common to install a special lifting device, but such lifting device is complicated and expensive.

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

Figures 1 and 2 show an embodiment of the present invention, in which 1 is a device body fixed to the ceiling, a flexible pipe 2 is protruded from the center of the lower surface, and a horizontal operation plate 4 is attached to the tip of the flexible pipe 2. has been done.

Hook pieces 3.3 are also provided on the instrument body 1 near both sides of the flexible pipe 2.

Through-holes 5, 5 are formed at appropriate locations in the horizontal operation plate 4, and hanging strings 6, 6, which also serve as power lines to the lamp 7, are fixed at both ends, and the hanging strings 6, 6 are hooked in the middle. piece 3,3
It is further inserted into the through hole 5 of the horizontal operation plate 4 and suspended, and a lamp 7 is suspended from the lower end.

In such a lighting device, by changing the swinging state of the flexible pipe 2, the distance between the hook piece 3 and the hook portion of the hanging string 6 on the horizontal operation plate 4 changes, and the height of the lighting device 7 changes accordingly. Change.

The hanging string 6 is slightly bent at the part where it is inserted through the through hole 5 of the horizontal operation plate 4, and its frictional force firmly maintains the height of the lamp 7 at a constant level.

However, it is not necessarily necessary to insert the lamp through the through hole 5 of the horizontal operation plate 4, and the height of the lamp 7 can be kept sufficiently constant due to the rigidity of the flexible pipe 2.

Further, the number of lamps 7 is not limited to two, but may be one or more. In the case of multiple lamps, by swinging the flexible pipe 2, the lamps 7, 7 are moved up and down in relation to each other.

As described above, the present invention is based on a suspension string 6 attached to a swingable support such as a flexible pipe 2 having a horizontal operation plate 4 at its tip.
One end of the hanging cord 6 is locked, the middle of the hanging string 6 is locked with the hook piece 3, and the lamp 7 is suspended from the lower end. The height of the lamp 7 can be adjusted by changing the distance between the locking part of the hanging string 6 and the hook piece 3, and the height of the lamp can be changed with an extremely simple structure and easy operation.
