Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a curtain rail for a television studio, and more particularly to a television having a structure that allows installation and removal of curtains to be carried out extremely easily and easily. Regarding curtain rails for studios.

[Prior Art] In a television studio, a background horizon is fixedly installed from the back wall to part of the side wall, and in front of the background horizon, a curtain rail is suspended from the ceiling at a predetermined height. It is surrounded. A corridor, usually called a cat walk, is built on the side wall that is continuous with this horizon, and is slightly lower than the hanging height of the curtain rail.

The curtain rail has two rail bodies 1a and 1b having a dogleg-shaped cross section facing each other with a predetermined distance, as shown in FIG. 6 as a cross section and as shown in FIG. 7 as a partially cutaway side view. They are configured as a set. And on this rail, wheels 2a, 2b
A plurality of traveling cars 2 for installing curtains are mounted, each of which has hooks 2c for installing the curtains hanging vertically through the gap between the rail bodies 1a and 1b. 4 is a cover for preventing derailment of the traveling vehicle 2.

By the way, this curtain rail frequently attaches or detaches the curtains that serve as the background depending on the program being broadcast. In that case, several workers, usually two workers, climb the above-mentioned canopy and tie the hanging strings attached to the top of the curtain at approximately equal intervals to the hooks 2c of the traveling vehicle 2 ( It is customary to undo (when attaching) and unwinding (when removing).

[Problems to be Solved by the Invention] The work of installing and removing curtains according to the above-described aspect is quite difficult and heavy labor. This is because the curtain itself is quite heavy. For example, curtains in television studios vary depending on the size of the studio, but typically each curtain is 6 to 8 meters high and 15 meters long.
exceed. Although it depends on the material of the curtain,
Its weight is 0.2-0.5 kg/m ² .

Therefore, for example, when removing curtains,
When you untie the hanging string at the end, the weight of the curtain part that has already been untied and hung is added to the hanging string that you are trying to untie next, making it difficult to untie the hanging string. increase. Conversely, when trying to install new curtains, the weight of most of the curtains that have not yet been tied is applied during the first tying process, making the work extremely difficult for the operator.

For this reason, in order to reduce the load on the hanging curtains, one worker pulls up the curtains while the other worker quickly undoes the hanging strings. It was customary to tie them together.

The present invention solves the above-mentioned problems and makes it extremely easy to attach and remove curtains from curtain rails suspended throughout the studio, thereby reducing overwork of workers. The purpose of the present invention is to provide an extremely useful curtain rail for television studios.

[Means for Solving the Problems] In the course of intensive research to solve the above-mentioned problems, the present inventors made a part of the curtain rail suspended from the studio ceiling movable up and down. When installing and removing the partial curtain rail, it is possible to lower the partial curtain rail to the studio floor and perform the work from there, eliminating any interference caused by the curtain's own weight.After the work is completed, the partial curtain rail can be raised and the entire rail reassembled. We developed the present invention with the idea that it would be sufficient to restore the original state.

That is, the television studio curtain of the present invention is a curtain rail suspended from the ceiling of a television studio, and at least a portion of the rail is made up of a partial rail body that can be raised and lowered, and both end surfaces of the partial rail body and the The present invention is characterized in that a shutter means is disposed on each end face of the remaining rail main body connected to each of the both end faces.

The present invention will be explained below based on the drawings. FIG. 1 is a diagram showing a state in which the curtain rail of the present invention is installed around the ceiling in a television studio. In the figure, 1
1 is a curtain rail, and the whole is suspended from the ceiling by a plurality of supports 12. The traveling vehicles 2 described in FIGS. 6 and 7 are incorporated into the curtain rail 11, and a curtain 14 is tied to the hook 2c of each traveling vehicle by a hanging string 13.

Reference numeral 15 denotes a partial rail body which forms a part of the curtain rail and is suspended by a wire 15a so as to be able to rise and fall freely. FIG. 1 shows the curtain rail as a whole constructed by incorporating the partial rail bodies 15 at the proper locations. For example, when installing or removing a curtain, as shown in FIG. After gathering the curtains at the location of the partial rail body, the rail body is lowered to the floor surface and the work is carried out. After the work is completed, the partial rail body is lifted up, set again at a predetermined position, and assembled into the curtain rail.

An example of this partial rail body 15 is shown in FIGS. 3 and 4. FIG. 1 is a front view thereof, and FIG. 4 is a side view thereof. In the figure, reference numeral 111 denotes a rail, and its cross section is the same as that in FIG. 6. A pedestal 112 is mounted on the rail 111.
The rail 111 and the pedestal 112 are connected by a plurality of connectors 113. Frame 113
has wires 114a and 114b attached to its upper end, so that the whole can be moved up and down.

Both end surfaces 115a and 115b of the rail 111 are
When assembled into the entire curtain rail, it is closely connected to the remaining curtain rail main body and each end face (not shown).

The partial rail body 15 according to the present invention is characterized in that a shutter means 116 is provided on each end surface thereof. The shutter means is illustrated in FIG. 5 as a partial schematic diagram.

116a is a shutter plate, which blocks the cross-sectional cavity of the coupler 113 located on both end surfaces of the partial rail body. The rail 111 acts as a lower stopper. Reference numeral 116b denotes a solenoid, and as is well known, the solenoid is of a type in which an actuator 116c disposed at the center thereof moves in the horizontal direction by electromagnetic force. The actuator 116c and the shutter plate 116a are connected by a connecting means 116d such as a commonly used arm mechanism with A as a fulcrum, for example.

The actuator 116 is activated by an actuation signal to the solenoid.
c moves, and the interlocking movement is transmitted to the shutter plate 116a via the connecting means 116d, and the shutter plate 1
16a will move up and down.

This shutter means 116 is used to prevent the running vehicles gathered on the partial rail body from falling in a chain reaction when the partial rail body that is raised and lowered is tilted for some reason during the installation/removal work of the curtain. It will be placed in

That is, when installing or removing a curtain, the target curtain section is moved and concentrated to this partial rail body, and then the solenoid 116b is activated by an electric signal to lower the shutter plate 116a and remove the target curtain, that is, it. The connected traveling vehicles are confined within this partial rail body. Thereafter, the partial rail body is lowered, but even if the partial rail body is tilted at this time, the traveling vehicle will not fall from the partial rail body due to the effect of the shutter plate 116a. Note that the end surfaces 115a, 11
It is preferable that the above-mentioned shutter means is also provided on each end face of the remaining curtain rail main body corresponding to 5b.

After finishing the work on the floor, the partial rail body is raised with the shutter plate 116a lowered and set at a predetermined position. In that case, for example, if a limiter mechanism is attached to the top surface of the pedestal 112 and linked to the shutter means, the limiter mechanism will operate when the partial rail body is raised to a predetermined position.
The shutter means can be automatically operated to open.

[Effects of the Invention] As is clear from the above description, the curtain rail of the present invention eliminates the need to install and remove curtains on a canvas walk as in the past, and allows workers to use the floor freely. The work can be done on a surface. Therefore, the weight of the curtain on the hanging strings is extremely reduced, making it easier to untie and tie the hanging strings. The work can be done by just one person, contributing to labor savings. Since the work is carried out on the curtain that is in close contact with the partial rail body, the unraveling and tying work can be carried out extremely efficiently, making it possible to significantly shorten the working time.
Overall, the labor of the workers is significantly reduced compared to the conventional method, and its industrial value is extremely large.
