The thing described in 60-153431 is known.
(Hereinafter, this is referred to as Conventional Technology 1.)
A moving pulley is provided on the elevating portion, and the intermediate portion of the cable is engaged with the moving pulley to suspend the elevating portion. One end of the cable is wound by a single drum disposed on the fixed portion side, and the other end is attached to the fixed portion. In addition, a contact for electrical connection with the elevating section is provided between the cables of the fixed section, and when the elevating section reaches the highest position, this contact comes into contact with the contact on the elevating section side. Electrical connection is made.

Further, as another elevating type lighting device, one described in Japanese Utility Model Publication No. 60-37762 is known. (Hereinafter, this will be referred to as conventional technology 2.) This lifting-type lighting device includes a drum fixed to output shafts at both left and right ends of a motor disposed in a base (box) mounted on the ceiling side, and both ends. Are wound on a pair of drums, respectively, and include a rope suspended from the base at an intermediate portion thereof, and an elevating portion having a pulley engaged with the intermediate portion of the rope. In this elevating lighting device, since both ends of the cable are wound by a pair of drums, the winding amount of each drum can be reduced by half as compared with the case of winding a single drum.

An electric winch, which is not an elevation lighting device but is used for suspending a measuring instrument in underground construction or the like, is disclosed in Japanese Utility Model Publication No. 53-48426. (Hereinafter, this will be referred to as prior art 3.) This electric winch winds up the ends of the ropes by a pair of drums which are arranged left and right, and the other ends of these ropes are intermediate sheaves and guides. It is hung downward through a sheave and suspends the suspended body. According to this electric winch, the lateral movement of the wire in the fleet angle of the drum can be absorbed by the intermediate sheave, so that the swinging and heaving of the suspended body can be reduced.

(Problem to be Solved by the Invention) In the elevating lighting device of the prior art 1, the other end of the rope engaged with the moving pulley of the elevating portion is fixed to the fixed portion, so that the elevating portion moves up and down. Sometimes one of the sheaves is always hung by a cable. As a result, the lifting unit may swing so as to incline in a direction in which one of the moving pulleys is hung, and the lifting operation becomes unstable. In particular, when the elevating unit swings up and rises near the highest position (top dead center), the contact of the fixed unit and the contact of the elevating unit do not make good contact, which hinders electrical connection.

Further, if the rope is not wound up uniformly on the drum, the rope becomes partially bulged at the winding portion. The part cuts into the winding part, which hinders the unwinding of the cord. In addition, there is a problem that the speed of lifting and lowering is low because the cable is wound by a single drum.

The up-and-down lighting device of the prior art 2 can wind up both ends of a wire with a pair of drums, so that the up and down time can be reduced, but it has the following problems.

In other words, since the elevating unit is directly hung by the drum, the rope moves right and left in the drum when winding and unwinding, and this is directly transmitted to the elevating unit. In addition, since both ends of the cable are wound, the roll of the cable is promoted in comparison with a structure in which one end is wound as in the prior art 1, and it is easy to induce the cable to be wound unevenly on the drum. .

Also, since a pair of drums are fixed to the driving shafts at the left and right ends of the motor respectively, two drums are inevitably required, which increases the cost. In addition, the drums, which are relatively many components, are spaced apart from each other. Therefore, miniaturization of the overall size of the apparatus is hindered.

Furthermore, in order to stably lift the elevating section, it is useful to increase the distance between the cords. However, if the distance between the pair of drums is increased, the size of the apparatus is further increased. There are evils.

The electric winch according to the prior art 3 winds up two wires with two drums, respectively, and has a problem that the elevating speed is slow as in the prior art. Furthermore, since the two drums are spaced apart, it is difficult to reduce the size of the entire apparatus.

[Structure of the Invention] (Means for Solving the Problems) The elevating lighting apparatus of the present invention is mounted on a ceiling side, and is disposed between a direction changing guide roller, a pair of guide rollers, and the pair of guide rollers. A base provided with fixed contacts; an electric motor provided in the base; a pair of drums connected to a driving shaft on one side of the electric motor; and both ends wound on the pair of drums, respectively. And a rope whose width is wider than a winding distance of the drum by the direction changing guide roller, and a middle part of which is suspended from the base via a pair of guide rollers; A moving pulley to be engaged with, and a movable contact provided, and an elevating unit suspended by the cable so that the movable contact is raised by winding the pair of drums and the movable contact comes into contact with the fixed contact; Take Characterized by comprising a; and vignetting luminaire.

In the present invention, a pair of direction change guide rollers may be provided in correspondence with each of the ropes led out from the drum, but may be provided in correspondence with only one of them so as to widen the distance between the ropes.

Further, the winding interval of the drum means an interval between the winding surface ends of the drums that are not adjacent to each other, that is, it corresponds to the maximum interval between the ropes derived from the pair of drums.

According to the present invention, since the rope engaged with the moving pulley of the elevating unit is wound at both ends simultaneously, the moving pulley is less likely to be wound around the rope when the elevating unit moves up and down, and the inclination of the elevating unit is reduced. And swing can be reduced. Therefore, the connection between the contact of the fixed portion and the contact of the lifting / lowering portion can be favorably performed.

Also, compared to a cable with one end fixed,
The amount of cable wound on the drum can be reduced by half, the lifting time can be reduced by half, and the rise of the cable wound on the drum is also relatively small, so that it is difficult for the cable to bite and good unwinding is possible. Can do.

In addition, since the middle portion of the rope passes through a pair of guide rollers, its position is hung down from the base body while its position is regulated, so that the side of the elevating portion which is promoted when winding or unwinding both ends of the rope is promoted. Shaking can be reduced.

Further, since the pair of drums for winding both ends of the cable are provided on one side of the electric motor so as to be connected to the driving shaft, the manufacturing cost can be reduced when the pair of drums are integrally formed. In addition, the size of the entire device can be reduced by being provided collectively on one side of the electric motor. Furthermore, when a pair of drums are collectively provided on one side of the electric motor in this way, the spacing between the cords is reduced, but the cords are turned by the turning guide rollers, and the gap is widened. The spacing between the ropes that suspend the elevating unit can be made sufficiently large, and the elevating unit can be stably moved up and down.
