Description

[Detailed Description of the Invention] This invention relates to a lifting device applied to high ceiling lighting equipment and the like.

Conventionally, when lifting or lowering this type of lighting equipment to replace lamps, etc., it was necessary to align the electrical contacts of the lifting part and the fixed part at the top dead center of the lifting part, or to keep the direction of the lighting equipment that is the lifting part constant. Therefore, it was necessary to provide a guide mechanism A as shown in FIG.

In the figure, B is the drum, C is the wire, D is the fixed part, and E
is the lifting part (lighting equipment), F is the slit f of the guide mechanism A
G is a guide shaft with a protrusion g on the elevating side.

However, this elevating device has the drawback that the guide mechanism A increases the height H of the entire device, making it difficult to apply it to ceiling-embedded fixtures.

Therefore, an object of this invention is to provide an elevating device that can maintain a constant direction of an elevating section and can be made thin.

An embodiment of this invention is shown in FIG.

That is, this elevating device consists of a fixing part 1 and an elevating part 2, and an elevating part storage recess 3 is formed on the central lower surface of the fixing part 1.
A motor drum 4 is disposed on the negative side, a first guide roller 5 is provided on the other side, and a second guide roller 6 is provided at the position of the recess 3.
The wire 7 has one end fixed at a position a predetermined distance from the guide roller 6 of the recess 3, hangs down from the fourth part 3, and is wound around a pair of movable pulleys 8 of the elevating part 2, and is connected to the recess. 3 to the second guide roller 6 and the first guide roller 5, and is wound around the drum.

The elevating part 2 has dimensions that fit into the storage recess 3,
A lighting fixture (not shown) is installed integrally with the elevating section 2 or on its lower surface.

When the motor is driven to rewind and rotate the drum 4, the elevating section 2 moves downward due to its own weight.

In the case of high-ceiling lighting equipment, lamp replacement is performed in this way.

Further, when the motor is rotated in the reverse direction, the elevating section 2 moves upward and is stored in the storage section 3.

At this time, since there are two wires 7 for hanging the elevating part 2, rotation of the elevating part 2 is suppressed, the orientation becomes constant, and the elevating part 2 is correctly stored in the storage recess 3.

Therefore, electrical contact (not shown) can be reliably contacted.

Furthermore, since the distance between the guide roller 5 and the drum 4 can be increased, the wire 7 can be wound neatly.

Incidentally, the lifting device of this invention has one drum and one drum as described above.
This includes not only hanging two wires by hanging the main wire, but also hanging multiple wires by two drums and two wires.

As described above, the elevating device of this invention has an elevating part that moves up and down, a recess that accommodates the elevating part at the top dead center of the elevating part, and a fixed part that has a built-in drum in the side of the recess. a guide roller disposed on the opposite side of the recess of the fixing part and facing the drum; It is characterized by comprising a hanging cable hanging the lifting part on a hanging part, and power is supplied to the lifting part in a state where the lifting part is housed in the four parts, so that the direction can be constant, and Since the conventional guide mechanism is not required, it can be made thinner, and the structure is simple, making it easy to apply to ceiling-embedded fixtures such as those in high ceilings.The distance between the guide roller and the drum can also be increased, making it possible to neatly wind the hanging cable around the drum. This has the effect of allowing you to go up and down without any trouble.
