Description

Technical Field

[0001] The utility model relates to the technical field of stage performing arts equipment, in particular to a folding stage opening in a theater. Background Art

[0002] The false proscenium is a device commonly used in theaters to install stage lighting facilities. The main functions of the false proscenium are to install the lamps inside the proscenium and adjust the size of the performance proscenium to meet the performance needs of different drama types. The false proscenium can be divided into fixed type and movable type according to its installation form. The fixed type is commonly used in small theaters, and the movable type is mostly used in large and medium-sized theaters to adjust the proscenium size.

[0003] Chinese Patent with Publication No. CN212957834U discloses a folding stage opening in a theater. By setting the cornice curtain, not only can the shape of the cornice proscenium be formed on the false proscenium, but also dynamic changes can be formed through the lifting of the cornice curtain to adapt to the performances of different stage scenes. In addition, when the cornice curtain is unfolded downward until it completely blocks the proscenium, it can be used as a closed barrier for the proscenium. At the same time, after the cornice curtain is completely flattened downward, it is also convenient for transportation and storage during non-stage performances. Thus, the false proscenium is flexibly adjustable to meet the use of various stage scenes.

[0004] During the use of this folding stage opening, the curtain is wound and retracted by a drum curtain to realize the lifting of the curtain. However, due to the curtain material factors and the large area, it is easily affected by external factors or human interference during the winding process, resulting in wrinkles in the curtain during the winding process, thereby affecting the curtain winding effect and the flatness of the curtain. Long-term use is likely to cause damage to the curtain and increase the user cost.

[0005] Therefore, a folding stage opening in a theater is proposed. Summary of the Invention

[0026] Please refer to Figures 1 to 6 , the present utility model provides a technical solution:

[0027] A folding stage opening inside a theater, including a vertical frame 100, a stage opening 100-1 corresponding to the performance area on the stage is provided on the vertical frame 100, an eaves curtain 200 is provided above the stage opening 100-1 on the vertical frame 100, a lifting mechanism 300 for driving the eaves curtain 200 is provided on the vertical frame 100, the lifting mechanism 300 drives the eaves curtain 200 to unfold downward along the height direction of the stage opening 100-1 to block the stage opening 100-1 or fold upward along the height direction of the stage opening 100-1 to avoid the space below the stage opening 100-1, a reel curtain 800 is provided at the upper part of the stage opening 100-1 on the vertical frame 100 and at a position behind the eaves curtain 200 along the depth direction of the stage opening 100-1, the reel curtain 800 is arranged at an interval from the eaves curtain 200, a smoothing component 900 is arranged on the upper side of the reel curtain 800, and the smoothing component 900 is fixed to the vertical frame 100, and the lower side of the smoothing component 900 is in a fitting design with the reel curtain 800.

[0028] The reel curtain 800 includes a curtain cloth 801, a reel 802 and a reel motor. The curtain cloth 801 is wound around the outside of the reel 802. The reel 802 is rotationally matched with the vertical frame 100. The reel motor is fixedly connected to the vertical frame 100, and the reel motor drives the reel 802 to rotate forward and backward, so that the curtain cloth 801 unfolds downward in response to the forward rotation of the reel 802 or winds upward in response to the reverse rotation of the reel 802.

[0029] Specifically, as Figures 4 - 6 shown, the smoothing component 900 includes a fixed shaft 901 arranged on the upper side of the reel 802. A smoothing plate one 902 and a smoothing plate two 903 are respectively movably connected to both sides of the fixed shaft 901, and the smoothing plate one 902 and the smoothing plate two 903 have the same structure. The lower ends of the smoothing plate one 902 and the smoothing plate two 903 are attached to the surface of the curtain cloth 801. Both ends of the fixed shaft 901 are fixedly connected with sliders 904. A sliding groove is arranged inside the vertical frame 100. The sliders 904 are slidably connected with the sliding groove. A spring 905 is fixedly connected between the upper end surface of the slider 904 and the support of the vertical frame 100, and the number of the springs 905 is two groups and is symmetrically distributed. Two rotating grooves 908 are staggeredly arranged on the outside of the fixed shaft 901, and a collar 907 is rotatably connected inside the rotating groove 908. A connecting piece 906 is fixedly connected to the outside of the collar 907. The two connecting pieces 906 are respectively fixed to the smoothing plate one 902 and the smoothing plate two 903. The collar 907 is sleeved on the outside of the fixed shaft 901, and the collar 907 is rotationally connected with the fixed shaft 901.

One end of the torsion spring 909 is fixed to the fixed shaft 901 and the other end is fixed to the inner wall of the collar 907.

[0030] During operation, when the drum curtain 800 runs and the curtain 801 is wound up by the reel 802, the curtain 801 can always be in contact with the first flattening plate 902 and the second flattening plate 903, which plays a role in flattening the curtain 801 during the winding process, reducing wrinkles in the curtain 801 during the winding process. And as the thickness of the curtain 801 on the reel 802 increases, the slider 904 moves upward in the chute and then compresses the spring 905. With this structure, it can be ensured that when the reel 802 winds up the curtain 801, the first flattening plate 902 and the second flattening plate 903 displace as the winding thickness of the curtain 801 increases. At the same time, the first flattening plate 902 and the second flattening plate 903 can also rotate in the rotating groove 908 outside the fixed shaft 901 through the connecting member 906 and the collar 907 as the winding thickness of the curtain 801 on the reel 802 increases, and then store elastic potential through the coil spring 909, ensuring that the first flattening plate 902 and the second flattening plate 903 can always be in contact with and fit the curtain 801 to achieve the flattening effect of the curtain 801.

[0031] The vertical frame 100, the proscenium 100-1, the cornice curtain 200, the lifting mechanism 300, and the drum curtain 800 disclosed in this application are all of a prior art (Chinese patent with publication number: CN212957834U).

[0032] Working principle: When the drum curtain 800 runs and the curtain 801 is wound up by the reel 802, the curtain 801 can always be in contact with the first flattening plate 902 and the second flattening plate 903, which plays a role in flattening the curtain 801 during the winding process, reducing wrinkles in the curtain 801 during the winding process. And as the thickness of the curtain 801 on the reel 802 increases, the slider 904 moves upward in the chute and then compresses the spring 905. With this structure, it can be ensured that when the reel 802 winds up the curtain 801, the first flattening plate 902 and the second flattening plate 903 displace as the winding thickness of the curtain 801 increases. At the same time, the first flattening plate 902 and the second flattening plate 903 can also rotate in the rotating groove 908 outside the fixed shaft 901 through the connecting member 906 and the collar 907 as the winding thickness of the curtain 801 on the reel 802 increases, and then store elastic potential through the coil spring 909, ensuring that the first flattening plate 902 and the second flattening plate 903 can always be in contact with and fit the curtain 801 to achieve the flattening effect of the curtain 801.
