Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an improvement of an elevating lighting device, and more particularly to a device that can reliably support a rectangular elevating lighting device at a predetermined location such as a ceiling surface.

[Conventional technology and its problems]

BACKGROUND OF THE INVENTION Conventionally, elevating lighting equipment has often been used for lighting equipment installed on relatively high ceilings such as gymnasiums and hotel lobbies in order to easily and safely perform maintenance and inspection of the lighting equipment or replacement of lamps.

For example, as shown in FIG.
The lighting fixture 5 is supported by a wire 3 and a fitting rod 4 that supports the lighting fixture at its lower end is locked.

By the way, in this device, the lower surface of the fitting tube 2 is made into an inclined surface, and furthermore, a vertically elongated slit is provided at the top of the inclined surface, so that the fitting rod 4 slides along the inclined surface, and the fitting rod 4 protrudes. The portion 6 is inserted into the slit of the fitting receiver 2, positioned, and locked.

However, before the fitting rod 4 is fitted into the fitting receiver 2, the fitting rod 4 tilts into the fitting receiver 2 and the tip thereof is fitted, resulting in the disadvantage that the fitting rod 4 is not fitted into the fitting receiver 2. There is.

In addition, since the lighting equipment rises while rotating, if the hole in the ceiling that supports the lighting equipment is square, and the lighting equipment is square, the lighting equipment cannot be rotated within the hole and will not fit properly. If the vertical dimensions of the mating rod and the fitting receiver are short, there is a drawback that the lighting fixture cannot be fitted and supported in a predetermined location.

Note that there are restrictions on the dimensions of the ceiling space of a building, and the vertical dimension of the vertical lighting device cannot be made smaller than a predetermined value.

[Purpose of the invention]

The present invention has been invented in view of the above points, and is an elevating lighting device that can reliably support an elevating lighting device and can also support a rectangular lighting device by fitting it into a rectangular hole in a ceiling surface or the like. The purpose is to provide equipment.

[Means for solving problems]

The present invention will be explained below with reference to FIGS. 1 to 3. In the figure, 11 is the main body of the vertical lighting device, 12
13 is a winding drum rotatably provided inside the lifting lighting device main body 11, and 13 is a plurality of guide rods provided at predetermined intervals on the lower surface of the lifting lighting device main body 11,
For example, install three wires at 120 degree intervals. Reference numeral 15 denotes a slide body whose lower surface is an inclined surface, and reference numeral 16 denotes a guide body provided on the lower surface of the vertical lighting device main body 11, which has a vertically elongated guide groove 17 on its inner surface. The uppermost part 18 is combined with the uppermost part 18. 19 is a guide plate having a fitting rod insertion hole 20 in the center and supported by the guide rod 13 so as to be movable up and down; 21 is provided protruding from the upper part of the illumination lamp body 22, for example, from the side of the guide plate mounting arm 29; The slide body 1 is a protrusion.
5 and rises along the guide groove 17 of the guide body 16.

23 is a fixed contact mount having a fitting rod insertion hole 24 provided on the lower surface of the vertical lighting device main body 11; 25 is a fixed contact provided on the lower surface of the fixed contact mount 23;
6 is a movable contact mounting base, 27 is a movable contact mounting base 26
28 is a socket mounting base supported on the guide plate mounting arm 29; 30 is a socket supported on the socket mounting base 28; 31 is an elastic spring for supporting the socket 30 on the socket mounting base 28 in a flexible manner. The socket 30 is configured to expand and contract with respect to the socket mounting base 28. 32
is a wire for hanging and supporting lighting equipment,
33 is a fitting rod supported by the guide plate mounting arm 29.

[Action of the invention]

(1) In the above lighting device for lifting, when the winding drum 12 is rotated and the wire 32 is wound up, the fitting rod 33 is inserted into the fitting rod insertion hole 20 in the center of the guide plate 19 and guided. The protrusion 21 engages with the guide groove 17 of the body 16, and the socket 30 and the like rise directly upward together with the guide plate 19 without rotating as a whole.

(2) When the socket 30 etc. rises, the movable contact 27 contacts the fixed contact 25 at the top and is electrically connected.

In addition, since the spring 31 is provided in the socket 30, for example, when configured as a recessed lifting lighting device, the socket 30 will be pulled up by the spring 31, and a gap will be created between the lighting body 22 and the ceiling surface. There is no.

(3) When lowering the illumination lamp, it can be lowered by rotating the winding drum 12 in the opposite direction.

〔Effect of the invention〕

As described above, the present invention provides a plurality of guide rods at predetermined intervals on the lower surface of the vertical lighting device main body, a guide member having a vertically elongated guide groove on the inner surface, and a fitting rod insertion hole in the center of the guide rod. A guide plate having a guide plate is supported so as to be movable up and down, and a slide body having an inclined lower surface is provided at the lower end of the guide rod, and a fitting rod provided on the upper part of the lighting body is inserted into the fitting rod insertion hole of the guide plate. The fitting rod is inserted into the guide groove and the protrusion provided on the upper part of the lighting body is engaged with the guide groove of the guide body, so the fitting rod is fitted into the fitting rod insertion hole and the protrusion is engaged with the guide groove. By doing so, the illumination lamp body is supported reliably, and as described above, the illumination lamp body can be lifted and supported directly above, so that a rectangular lighting fixture can be fitted and supported in a rectangular hole.

Furthermore, since the socket for mounting the light source is located in the space between the guide rod and the guide body, there is an advantage that the vertical width of the entire device can be configured to be small.
