Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a horizont curtain storage structure for storing a horizont curtain when not in use by lifting it above the stage.
[0002]
[Prior art and its problems]
For example, as shown in FIG. 3, the horizont curtain 1 may be hung down on the theater stage S or the like so as to be on the back wall W of the stage S in order to enhance the production effect. In many cases, the horizont curtain 1 is lifted above the stage S when 1 is not used.
[0003]
At this time, if the height up to the board G placed above the stage S is not sufficient, the horizont curtain 1 is wound up in a roll shape as shown in a virtual diagram in FIG.
[0004]
Therefore, it becomes easy for the horizont curtain 1 to have a curl, and if it is severe, the curl will cause distortion such as distortion in the image projected on the horizont curtain 1, and the horizont curtain 1 will be in a short period of time. Had to be replaced.
[0005]
Nonetheless, no proposal has been made to solve this problem, and the present invention provides a horizont curtain storage structure that is optimal for overcoming this situation and expecting improved versatility. For the purpose.
[0006]
[Means for Solving the Problems]
In order to achieve the above-described object, the means of the present invention is a horizont curtain storage structure in which a horizont curtain suspended below a stage wall when used is suspended above the stage when not in use. A baton lifting means that is suspended, and a horizontal curtain lifting means that is held horizontally so as to be movable on a slat provided above the stage. The horizontal curtain lifting means is interposed between the rotating body and the rotating body. It consists of a tow body and a counterweight that is connected to the lower end of the tow body and hangs down.The baton lifting means is connected to the lower end of the horizont curtain, and the upper end of the tow body is connected to the upper end of the horizont curtain. When the lower end of the horizont curtain is lifted by the baton lifting means, the upper end of the horizont curtain is lifted while lowering the counterweight. It is.
[0007]
Therefore, the horizont curtain 1 in the lifted state forms a U-turn portion that is folded in half. However, since the U-turn portion is not tightly folded, no crease is generated in the U-turn portion.
[0008]
Not only that, when the horizont curtain is folded in two, the upper and lower positions of the horizont curtain are shifted in the vertical direction so that the same place does not always become a U-turn part. Makes it harder to generate wrinkles.
[0010]
Further, it is possible to increase the horizontal distance between the upper and lower ends of the suspended horizont curtain, and as a result, it is possible to further reduce the pressure that acts on the U-turn portion of the horizont curtain and causes wrinkles. become.
[0012]
Furthermore , if the lower end of the horizont curtain is lifted on condition that the weight of the counterweight and the horizont curtain is appropriately set, the upper end of the horizont curtain can be naturally raised.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below based on the illustrated embodiments. The horizont curtain storage structure according to the present invention suspends the horizont curtain 1 that is suspended so as to be opposite to the back wall W of the stage S when used, and is suspended from above the stage S when not in use. A baton lifting means 3 and a horizontal curtain lifting means 2 held horizontally by a slat G placed above the stage S.
The horizont curtain lifting means 2 includes a rotating body 21, a pulling body 22 interposed in the rotating body 21, and a counterweight 23 that is connected to the lower end of the pulling body 22 and hangs down.
The baton lifting means 3 is coupled to the lower end of the horizont curtain 1, the upper end of the traction body 22 is connected to the upper end of the horizont curtain 1, and the counterweight is lifted when the lower end of the horizont curtain 1 is lifted by the baton lifting means 3. The upper end of the horizont curtain 1 is lifted while lowering 23.
[0014]
That is, in the present invention, as shown in FIG. 1, the horizont curtain 1 that is suspended so as to be next to the back wall W of the stage S when used is held by the slats G arranged above the stage S. The horizontal curtain lifting means 2 is suspended.
[0015]
When the horizont curtain 1 is stored, as shown in FIG. 2, the lower end of the horizont curtain 1 is lifted by the baton lifting means 3 suspended from above the stage S, and the upper end of the horizont curtain 1 is lifted by the horizont curtain lifting means. It is going to be lifted by 2.
[0016]
Incidentally, the baton lifting means 3 includes a traction body 32 that holds a baton coupler 31 having an appropriate configuration at the lower end, and the traction body 32 is a dedicated winch 33 (see FIG. 2). It is said that it will be pulled out from and rolled up.
[0017]
Therefore, in the horizont curtain 1 at the time of storage, a so-called U-turn portion 1a (see FIG. 2) folded in half is formed, but this U-turn portion 1a is not so tightly bent. No creases caused by the formation of the U-turn portion 1a will occur.
[0018]
Not only that, when the horizont curtain 1 is folded in two, the upper end position and the lower end position of the horizont curtain 1 are not always the same position, that is, the mutual positions are shifted in the vertical direction. The U-turn portion 1a is not used, and as a result, it becomes difficult for wrinkles to occur in the U-turn portion 1a.
[0019]
By the way, the horizont curtain 1 has a baton 11 at the upper end and a baton 12 at the lower end, so that the load distribution at the upper and lower ends of the horizont curtain 1 is made uniform so as not to cause vertical warp in the horizont curtain 1. is doing.
[0020]
Therefore, when the baton lifting means 3 is connected to the baton 12 on the lower end side, and the horizont curtain lifting means 2 is connected to the baton 11 on the upper end side to suspend the horizont curtain 1 above the stage S, the horizont curtain 1 As a matter of course, it is possible not to generate downspouts in the entire horizont curtain 1 as well as to prevent downspouts from occurring in the upper and lower end portions.
[0021]
At this time, the horizont curtain lifting means 2 includes a rotating body 21 such as a so-called idling sheave and a pulling body 22 such as a wire whose one end that is interposed by the rotating body 21 is connected to the upper end of the horizont curtain 1. And a counterweight 23 which is connected to the other end opposite to one end of the pulling body 22 and hangs down.
[0022]
Incidentally, in the illustrated case, the rotator 21 is a sheave because the traction body 22 is a wire, but in short, any configuration that can raise the upper end of the horizont curtain 1 to a predetermined height position is sufficient. .
[0023]
Therefore, although not shown, the traction body 22 may be a chain and the rotary body 21 may be a sprocket. However, from the viewpoint of avoiding the so-called noise generation, the configuration including the illustrated wire and sheave is preferred. Is preferred.
[0024]
The rotating body 21 is pivotally supported so as to allow so-called idling. In short, as long as the so-called movement of the towing body 22 is enabled, the rotating body 21 does not rotate itself but the towing body 22 slides. Needless to say, an appropriate mechanism or structure that allows the
[0025]
The counterweight 23 is not shown in the figure, but a baton may be used instead. It is sufficient that the counterweight 23 has a weight sufficient to lift the upper end of the horizont curtain 1.
[0026]
By the way, in the Horizont curtain lifting means 2,
W ₁ ; weight of horizont curtain 1 W ₂₂ ; weight of puller ₂₂ W ₂₃ ; weight of counterweight 23 W ₁₁ ; weight of baton 11 W ₁₂ ; and weight of baton 12 W ₁₁ + W ₂₂ + (W ₁ / 2) <W ₂₃ <W ₁₁ + W ₁ + W ₁₂ When the above equation is established, the upper end of the horizont curtain 1 is lifted by the weight of the counterweight 23 by lifting the lower end of the horizont curtain 1 with the baton lifting means 3.
[0027]
That is, conventionally, when the horizont curtain 1 is folded and lifted, the upper and lower ends of the horizont curtain 1 are lifted by the baton lifting means 3 respectively. Therefore, there are two winches constituting the baton lifting means 3. However, in the present invention, a single winch, that is, a single baton lifting means 3 is sufficient.
[0028]
In the present invention, the horizont curtain lifting means 2 is held so as to be horizontally movable by the slat G arranged above the stage S. Therefore, the horizont curtain lifting means 2 is horizontally moved by the slat G. As a result, the horizontal interval between the upper end and the lower end of the suspended horizont curtain 1 can be separated, and as a result, pressure acting on the U-turn portion 1a of the horizont curtain 1 and causing wrinkles is reduced. It becomes possible to further reduce.
[0029]
【The invention's effect】
According to the present invention, the following specific effects can be achieved.
1) The U-turn part formed when the horizont curtain is folded in half is not forcibly folded, not to cause no curl in the horizont curtain suspended above the stage. This will not cause creases in the part.
2) When the horizont curtain is folded in two, it can be avoided that the upper end position and the lower end position of the horizont curtain are always in the same place, so that the same place does not become a U-turn part, and as a result, the U-turn It will make it difficult to generate wrinkles on the part.
3) By horizontally moving the horizont curtain lifting means, the horizontal distance between the upper and lower ends of the suspended horizont curtain can be increased, and as a result, the pressure acting on the U-turn portion of the horizont curtain is increased. Can be further reduced.
4) When the lower end of the horizont curtain is lifted by the baton lifting means, the upper end of the horizont curtain is simultaneously lifted by the horizont curtain lifting means while lowering the counterweight, so a plurality of baton lifting means are not required and a single baton lifting means is required It is advantageous in that it is sufficient if is prepared.
5) As a result, according to the present invention, even when the use and storage of the horizont curtain are repeated for a long period of time, it is possible to avoid the winding curtain from being attached to the horizont curtain and to improve its versatility. Ideal for expecting.
