Description

[Detailed Description of the Invention] The present invention relates to a lighting fixture that is equipped with a lifting device so that the height of the lighting fixture can be freely adjusted, and aims to facilitate the attachment and detachment of a shade.

As shown in FIG. 1, a lamp 1 having a lamp socket 2, a shade 3, and a lifting arm 4 is suspended from a lifting device 6 by a wire 5, connected to a power source by a cord 7, and the lamp 1 is held by the arm 4. When a lighting fixture whose height can be adjusted by going up and down is installed in a kitchen or the like, the shade gets dirty with oil and dust and must be cleaned frequently.

The present invention allows the shade to be easily attached and removed with the socket and lamp still attached, making it easy to clean the shade.

FIG. 2 is a sectional view of a main part of an embodiment of the present invention, and FIG. 3 is an exploded perspective view of a part thereof.

In these figures, 3 is a shade, and 4 is a pair of U-shaped pipe-shaped lifting arms provided vertically on both sides of the socket 2 of the lamp 1.

In the present invention, a stopper 8 with a swollen pipe diameter is provided at the shade attachment position on the vertical part of the arm 4, and a vertical groove 10 that fits into the pipe-like arm 4 is provided at a corresponding point on the diameter inside the shade 3.
A pair of thick-walled shade fittings 9 having a diameter are attached to a decorative plate 11 with screws 12.

When attaching the shade 3 to the lamp, as shown in FIG. Shade 3 above the horizontal part of 90
The arm 4 is rotated and lowered, and the arm 4 is fitted into the vertical groove 10 of the shade fixture 9 as shown in the figure, and the shade 3 is mounted on the arm 4 by placing it on the stopper 8.

When removing the shade, the shade can be removed by performing the operations in the reverse order as described above.

5 and 6 are a sectional view and an exploded perspective view of another embodiment of the present invention.

In this embodiment, an inner shade 3b made of punching metal or the like is provided inside the outer shade 3A so that when the shade is doubled, the outer shade 3A and the inner shade 3B can be separated and removed. A first shade fitting 9A fixed to the outer shade 3A, and this shade fitting 9
It is intercepted by a second shade fitting 9B that removably fits into a circular or semicircular recess 13 provided in A, and a vertical groove 10 into which the arm 4 fits is formed in this second shade fitting 9B. This is what I did.

The fitting portion of the first shade fitting 9A and the second shade fitting 9B is formed to have a circular or semicircular curved surface so that the force applied from the outside is dispersed.

Further, a hole 14 into which a second shade fitting 9B is fitted is formed in the inner shade 3B.

When attaching the outer shade 3A and the inner shade 3B to the lamp 1, fit the fitting part 15 of the second shade fitting 9B into the hole 14 of the inner shade 3B, and then fit the shade fitting 9B into the shade fitting 9A. Then, in the same way as described for the previous embodiment, push up the shade from the underside of the lamp 1, rotate the shade 90 degrees above the lamp, and fit the arm into the vertical groove 10 of the shade fitting 9B. , placed on the stopper 8.

Also, when removing it, do the same thing as before.

As described above, in the present invention, the shade can be attached and detached without using any tools while the socket or lamp is attached to the lamp, making it easy to clean the shade.

In addition, the mounting position of the shade can be set arbitrarily by the position of the stopper 8, and since the vertical groove 10 of the shade fitting 9 fits into the pipe-shaped arm 4, by making it thicker. Since the tilt in the vertical direction is regulated, it is possible to prevent the shade from tilting even if there is some weight imbalance in the shade.

In addition, the shade cannot be removed from the arm unless the shade fixture 9 is pushed upwards above the horizontal part of the upper part of the arm 4, so the shade will not come off due to vibrations caused by lifting or lowering the lighting equipment or by touching the shade with your hand. Effects such as preventing the position of the arm from shifting or coming off the arm can be obtained.
