Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to the improvement of a lifting lighting device, and in particular, the invention relates to the improvement of an elevating lighting device, in particular, to raise the lighting equipment with directionality, to reliably support the lighting equipment at a predetermined location, and to improve the lighting equipment. This invention relates to a device capable of reliably winding and unwinding a wire on which a device is suspended on a winding drum.

[Conventional technology and its problems]

For example, as shown in FIGS. 4 and 5, a conventional general type lifting lighting device has a fitting tube 2 provided at the lower end of the lifting device main body 1, and a fitting tube 2 provided on the upper surface of a lighting fixture 3 that can be raised and lowered freely. A fitting rod 4 is suspended by a wire 5, and the fitting rod 4 is configured to be fitted into the fitting cylinder 2.

By the way, if a lifting lighting fixture is supported by a single wire, the lighting fixture will rise while rotating.

If the lighting fixture rises while rotating, there will be no problem if the lighting fixture is located below the ceiling. However, with recessed lighting devices, the external shape of the lighting fixture matches the hole in the ceiling surface, and it is necessary to raise the lighting fixture to fit into the hole, but the external shape of the lighting fixture is square. In some cases, the disadvantage is that it is difficult to fit the luminaire into the cavity because the luminaire is rotating.

Furthermore, when the wire 5 is wound around a winding drum and the number of windings increases, a strong tensile force is applied to the wire 5 when the fitting rod is locked, and the wire to be wound gets wedged between the wound wires 5. The disadvantage is that the wire cannot be rewound.

[Purpose of invention]

The present invention has been devised in view of the above points, and is designed to raise the lighting equipment in a directional manner, to securely support the lighting equipment at a predetermined location, and to wrap the wire that hangs the lighting equipment. It is an object of the present invention to provide a device capable of reliably winding and unwinding onto a take-up drum.

[Means for solving problems]

The present invention will be explained below with reference to FIGS. 1 to 3. In the figure, 11 is a lifting device main body fixed to a surface to which it is attached, 12 is a winding mechanism supported inside the lifting device main body 11, 13 is a motor for rotating the winding mechanism 12, and 14 is a winding device. It is a wire that is wound around the take-up mechanism, and the upper half is a round wire 15.
The lower half is made up of a flat wire 16. The flat wire 16 is made of, for example, a stainless steel plate,
The width is about 1.5 cm and the length is about 150 cm. 17 is a lighting fixture supported at the lower end of the flat wire 16; 18 is a pair of rollers provided below the lifting device main body 11 at a location corresponding to the wire 14; when the flat wire passes, the direction of the lighting fixture 17 is The lighting equipment has directionality and is supported at a predetermined location.

[Effect of invention]

In the above device, when the winding mechanism 12 is rotated and the lighting fixture 17 is raised, a predetermined length of the round wire 15 is wound around the winding drum, and then the flat wire 16 is passed through the roller and onto the winding drum. rolled around. When the flat wire 16 passes through the rollers, the direction of the lighting fixture 17 is determined, and if the lighting fixture 17 is configured in a downlight shape, for example, the lighting fixture 17 can be reliably supported at a predetermined location on the ceiling surface. Also, when the fitting rod is locked or unlocked and a strong tensile force is applied to the wire, the flat wire 16 is wound around the winding drum, so the round wire 15 that has already been wound is unwound. The wire that is being unrolled will not get wedged.

[Effects of the invention] As described above, the present invention supports a wire whose upper half is made of a round wire and whose lower half is made of a flat wire in a rotatable winding mechanism. Since the device is configured to suspend and support the lighting equipment at the bottom end, when lifting the lighting equipment as described above, the direction of the lighting equipment can be determined and the lighting equipment can be reliably supported at a predetermined location. ,
In addition, when the mating rod is locked or unlocked and a strong tensile force is applied to the wire, the flat wire is wound around the winding drum, preventing the wire from getting caught in the round wire. This has the advantage that the lighting fixtures can be raised and lowered reliably.
