Description

Lifting equipment for stage properties

The present invention relates to a stage prop lifting device, and more particularly, a device for elevating stage props such as a projector for screening a movie at a performance hall or an illuminator for a performance. Minimized, and easy to install the stage accessory lifting device.

Generally, stage props such as projectors and illuminators weigh a lot, so they cannot be raised or lowered manually.

However, these stage props simply use a lifting method using wires, so there was a problem of swinging back and forth and left and right during lifting. To prevent this, a stretchable stand is placed between the upper support plate fixed to the ceiling and the lower support plate to which the stage accessory is installed. It is installed to prevent shaking.

Such a conventional stage prop lifting device is, as shown in Figure 1, a plurality of expansion and contraction plate (9) is integrally formed by the hinge coupling, and the expansion stage (1) It consists of an upper support plate (2) and the lower support plate (3), the upper support plate (2) is a reduction motor (5) is installed on both sides of the wire drum (4), the wire wound on the wire drum (4) Guide rollers (7) are held at the corners and fixed to the ceiling, and the lower support plate (3) is equipped with a stage accessory (projector or illuminator) at the bottom, and guides at upper corners. The end of the wire 6 through the roller 7 is coupled to the structure.

The wire drum (4) is rotated as the deceleration motor (5) is driven, the wire is released or wound, and the expansion table (1) is a plurality of expansion plates (9) hinged to the "X" shape It has a flexible structure, so it has elasticity, and its length is made to stretch according to the change in the length of the wire.

That is, when the length of the wire is increased, it is lowered by the weight of the lower support plate 3 to which the projector is attached, and the stretchable base 1 is lengthened by a plurality of expansion and contraction plates 9 forming a hinge coupling. On the contrary, when the wire 6 is wound around the wire drum 4, the lower support plate 3, to which the end of the wire 6 is coupled, is pulled up, and the stretchable base 1 decreases in length.

The rotation of the wire drum 4 is controlled by the limit switch unit installed in the reduction motor, and as a result, the lifting limit of the lower support plate 3 is controlled to effectively raise and lower the stage accessory 8. It will be possible.

However, the stage small lifting device is provided with a guide roller (7) at each corner portion for holding the reduction motor (5) and the wire (6) wound on the wire drum (4) is installed on both sides of the wire drum (4) Support plate (2), a plurality of expansion and contraction plate (9) is hinged to the expansion and contraction length (1) of the length and stretch, each end of each wire (6) is coupled and the stage product (8) is installed at the bottom Consisting of a lower support plate (3), its configuration is very complicated, and the expansion and contraction (1) consisting of a plurality of expansion and contraction plate (9) is exposed to the outside, there is a problem that the appearance is degraded in use, in particular the wire drum (4) Each of the guide rollers 7 and the expansion table 1 has their own weight, and therefore, there is a problem in that installation workability of the stage prop lifting device is inferior.

Accordingly, the present invention has been made in order to improve the problems of the conventional stage prop lifting device, by installing a telescopic pipe between the upper and lower support plates to simplify its components while minimizing its own weight to improve the installation workability The purpose is to provide a lifting device.

In order to achieve the above object, the present invention is a box-shaped outer case, the upper support plate is formed in the center and the through hole is formed in the center and the thin plate is wound in the center, the upper end is attached to the through hole of the upper support plate, the length Is made of a flexible pipe that is variable, and the lower support plate is attached to the lower end of the expansion pipe and the stage accessory is installed on the lower side, the expansion pipe is the outer pipe formed in the longitudinal direction of the guide projection inward, the longitudinal direction inward It consists of a first inner pipe formed with a first guide protrusion and a first guide groove in the longitudinal direction to the outside, and a second inner pipe having a second guide groove in the longitudinal direction to the outside, and the lower support plate A coupling hole is formed in which the lower end of the lower fixing flange is fitted, and a closing plate is installed by a plurality of connecting bolts, and a stage accessory is provided therebetween. As installed, the lower end of the outer case is attached to the ceiling finishing material, and the expansion and contraction pipe is located in the interior of the outer case when using only the stage accessories are exposed to the outside and the exterior is beautifully treated, the outer pipe and the first The construction is simplified so that the lower support plate on which the stage accessories are installed is elevated by the expansion pipe composed of the inner pipe and the second inner pipe and the thin plate installed inside the expansion pipe, thereby minimizing the weight of the lifting device and improving installation workability. .
