Technical field

The invention relates to the technical field of stage performance equipment, in particular to a stage folding platform.

Background technique

Fake proscenium is a commonly used equipment for installing stage lighting facilities in theaters. The main function of fictitious proscenium is to install lamps inside the proscenium and adjust the size of the performance proscenium to meet the performance needs of different types of dramas. Fake proscenium can be divided into fixed type and movable type according to its installation form. The fixed type is often used in small theaters, and the movable type is mostly used in large and medium-sized theaters to adjust the size of the proscenium.

The existing movable false proscenium is restricted by multiple factors due to its requirements for building space and the complexity of its own structure. At present, the industry has not yet seen a kind of movable fake proscenium with simple structure and multi-dimensional adjustment of fake proscenium, which makes the application more extensive.

In addition, the existing fake proscenium has a single shape, which cannot meet the use of different stage scenes.

Summary of the invention

The present invention aims to solve one of the technical problems in the related art at least to a certain extent: to provide a stage folding platform, whose false platform is flexibly adjustable and has a simple structure, so as to meet the use of various stage scenes.

To this end, an object of the present invention is to propose a false stage stand, which includes a stand, the stand is provided with a stand corresponding to the performance area on the stage, characterized in that: the stand A cornice screen is provided on the frame above the platform, and a lifting mechanism for driving the cornice screen is provided on the stand, and the lifting mechanism drives the cornice curtain to expand downward along the height direction of the platform to cover the platform mouth or Fold in the height direction of the proscenium to avoid the space below the proscenium. By setting up the cornice screen, not only the shape of the cornice crown can be formed on the false countertop, but also dynamic changes can be formed by the lifting of the cornice screen, which can adapt to the performance of different stage scenes. In addition, the cornice screen expands downwards until it completely covers the crown. The closed barrier of the proscenium, and at the same time, when the cornice curtain is completely flattened down, it is also convenient for transportation and storage during non-stage performances.

As shown in the figure, the stand 100 has a door-shaped structure. Specifically, the stand 100 includes a top piece 101 and at least two side pieces 102. Preferably, the side pieces 102 are two spaced apart. The upper end of the sheet 102 is connected to the top sheet 101, and two adjacent side sheets 102 and the top sheet 101 are jointly enclosed to form a mesa 100-1. The said proscenium 100-1 refers to the open space channel between the two side panels 102 on the stand 100.

Embodiment two:

The basic structure is the same as that of the first embodiment above. The difference is that the cornice curtain 200 includes an upper beam 201, a lower beam 202 and a number of upright components 203. The lower beam 202 is located below the upper beam 201 and is parallel to the upper beam 201. All the upright components 203 are arranged between the upper cross beam 201 and the lower cross beam 202, and the upright components 203 are arranged in order along the width direction of the platform;
