Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a stage curtain, that is, a hanging curtain used on stages such as theaters.

Doncho is generally a thick curtain made of donsu, but the one of the present invention has a lattice-like structure composed of a horizontal bar 1 and a large number of connecting members 2 connecting the horizontal bars 1 and 1 above and below. A decorative plate 8 is attached to the frame A of , and the horizontal rod 1 and the connecting member 2 are connected through a twisting ring 4 fitted to the horizontal rod 1, and the twisting ring 4 is Consisting of two semicircular segmented rings 4a and 4b, arcuate and annular regulating flanges 7 and 6 are erected at the center and one side of both segmented rings 4a and 4b, and the connecting member 2 The upper and lower rounded portions 5 are fitted between the regulating flanges 6 and 7 of the twist stopper ring 4, and the decorative plate 8 is a plate-shaped body that spans the upper and lower horizontal bars 1, 1. , 1, and the lattice 3 of the bone body A is substantially covered by the decorative plate 8, which will be described later. This makes it possible to robustly produce a novel and unique stage curtain that is completely different and unparalleled anywhere else.

Below, one embodiment of the present invention will be explained based on the drawings. Fig. 1 shows a lattice-like frame A consisting of a horizontal rod 1 and a large number of connecting members 2 connecting the upper and lower horizontal rods 1, 1. In front view,
The horizontal rod 1 has a round cross section.

Doncho is usually a large curtain with a rectangular front that can be several tens of meters wide.

Incidentally, the three lattice meshes of the skeleton A shown in the figure are small and equivalent to several tens of centimeters square, so in order to finish the stage curtain of the present invention into a large screen of the same shape, the skeleton A must first be made to the same size. It is necessary to continue vertically and horizontally until

The size and shape of the lattice 3 of the frame body A are determined according to the length and spacing of the connecting members 2 in the same row that connect the upper and lower transverse rods 1, 1.

Then, the bone body made into a predetermined size in this manner is suspended on the stage using hanging fittings (not shown).

FIG. 2 is a perspective view of the connecting members 2a, 2b, and 2c.

The connecting member 2a is a round bar, the connecting member 2b is a thick plate, and the connecting member 2c is a thin plate, and round portions 5a, 5b, and 5c are formed by winding or perforating the top and bottom of the connecting member 2a, 5b, and 5c, respectively.

The round portion 5 has a size that fits into the twist stopper ring 4.

Figures 3 to 5 show the state in which the horizontal rod 1 and the connecting member 2 are in communication with each other via the anti-twist ring 4. Figure 3 is a perspective view, Figure 4 is a front view, and Figure 5 is the same as in Figure 4. Longitudinal side view.

Moreover, FIG. 10 is a front view of the twist stopper ring 4 in a separated state.

The semicircular segment rings 4a and 4b constituting the anti-twist ring 4 are fixed to the horizontal beam 1 with a pin 9, and the anti-twist ring 4 is fitted onto the horizontal beam 1.

The annular regulating flanges 6, 6 stand up on one side of the segmented rings 4a, 4b and face each other, and the arc-shaped regulating flanges 7, 7 stand up on the central part, that is, the back, of the segmented rings 4a, 4b and are continuous. The upper and lower round portions 5a, 5a are connected to the regulating flange 6,
The upper and lower connecting members 2a, 2a fitted between the twisting rings 4
The control flanges 6 and 7 prevent movement from side to side on the horizontal rod 1.

Further, the upper and lower round portions 5a, 5a do not collide with each other at the regulating flange 7.

The connecting members 2a, 2a are not fitted into the regulating flanges 6, 6, but are connected to the upper and lower round portions 5 when the segmented rings 4a, 4b are separated.
a, 5a are fitted between the regulating flanges 6, 7, and then the split rings 4a, 4b are assembled together.

The connecting members 2b and 2c are also connected to the transverse rod 1 via the twist prevention ring 4 in the above-described manner to form a predetermined lattice-shaped bone body A having lattice openings 3.

Since the connecting member 2c is wide, the anti-twist ring 4 is made correspondingly wide.

The opposing parts of the segmented rings 4a and 4b have a concave and convex engagement part 14b,
14a is provided to ensure that the twist prevention ring 4 is integrated.

Figures 6 and 7 show a flexible strip-shaped plaque 8 on the bone body A.
FIG. 6 is a front view, and FIG. 7 is a longitudinal side view of the device in a state in which it is attached.

Reference numeral 11 is a circular ring for arranging each decorative plate 8.

It is possible to mount a single wide decorative plate 8 to cover every lattice, and it is not necessary to mount such a decorative plate 8 to each lattice 3.

This is because it allows changes to be made to the stage curtain.

As shown in the perspective view of FIG. 8, the illustrated decorative plate 8 is provided with hanging grooves 10a and hanging pieces 10b at the top and bottom, and the lower part of the upper decorative plate 8 and the lower part of the lower decorative plate 8 are provided on the horizontal rod 1. By wrapping the upper part, inserting the hanging piece 10b into the hanging groove 10a, bending it, and fixing the upper and lower parts to the horizontal rod 1, the upper and lower lattices 3 are continuously covered. is attached to bone body A.

When such a decorative plate 8 is attached to the bone body A, it is easy to replace and remove it with another decorative plate, and the curtain can be changed to one with a different shape and pattern at any time.

FIG. 9 is a front view in which a plurality of thick plate-like decorative plates 8a are arranged in grids 3 of the bone body A.

The attachment method is arbitrary, but it is desirable that the attachment be removable.

In both cases, the plaque is a plate-shaped body that spans the upper and lower horizontal rods 1 and 1.
The upper and lower parts are fixed to the upper and lower transverse rods 1, 1, and the lattice 3 of the bone body A is still substantially closed.

Although the present invention has the above configuration, it goes without saying that each of the above-mentioned composition members may be made of metal, plastic, resin, cloth, leather, etc., or a combination thereof. do not have.

In the present invention, the skeleton, which has the basic composition of the horizontal rod and the connecting material, is connected through a twist prevention ring, which prevents distortion, twisting, rocking, etc. of the entire skeleton. The plaque is a plate-shaped body that spans between the upper and lower horizontal bars, and its upper and lower parts are fixed to the upper and lower horizontal bars, and the plaque is securely attached without causing any lifting or other problems on the plaque. It is incorporated into the skeleton, making the entire stage strong.

In this case, the curtain can be changed to any shape and size by adding or removing the necessary amount of horizontal bars and connecting members, and the shape and color of the plaques attached to the lattice can be changed. Depending on the situation, it is possible to create a unique form and pattern on the entire stage, and by replacing various parts of these decorative plates with others, it is possible to change into various types of stage curtains with a single skeleton. It is something.

In particular, by composing the stage curtain in this way, it not only improves the sound absorption effect but also makes it possible to assemble it on site.

Next, by making the curtain in the present invention made of metal,
Not only can the lighting effect be achieved by utilizing the reflection of light, but also the safety of theaters, etc. can be ensured by being non-flammable, and cleaning can be made convenient.

In addition, if it is made of light metal, it can be composed with a light weight, and it has many advantages that cannot be expected with conventional stage curtains, so it can be said to be extremely effective. .
