  A stage device composed of a plurality of panels according to the present invention will be described with reference to the drawings.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a view as seen from the back side of the stage (the side opposite to the audience). Reference numeral 1 in the figure indicates the stage apparatus as a whole.
The stage device 1 includes a driving device 2 and two panels 3a and 3b which are moved up and down by the driving device 2.
The drive device 2 includes two motors 4 and 5 and take-up reels 8a and 8b that rotate and feed out the two lines 6 and 7 by decelerating the rotations of the motors 4 and 5 by the speed reduction mechanisms 9a and 9b. Thus, the two motors 4 and 5 are driven and controlled by a power feeding control device (not shown).

On the other hand, the two panels 3a and 3b on which a small set such as a background pattern, a shoji, a sliding door, etc. are provided are the tips of the measures 6 and 7 of the reels 8a and 8b that are driven to rotate by the motors 4 and 5. The upper end portions of the panels 3a and 3b disposed up and down are connected to each other.
That is, the strip 6 fed out from the take-up reel 8a is guided by a plurality of pulleys 10, 10, and the leading end thereof is connected to the upper end of the upper panel 3a, and the strip 7 fed out from the take-up reel 8b is plural. Are guided by pulleys 11, 11, and connected to a lower panel 3 b via a moving mechanism 12 described later.

  As shown in FIG. 2, the moving mechanism 12 is provided with a guide rail 14 provided vertically on the back surface of the upper panel 3 a of the upper and lower panels 3 a and 3 b. A bearing portion 15 is provided on the flat surface of the shaft, and a shaft (pivot shaft) 17 provided at the upper end portion of the sled ball or L-shaped swinging arm 16 is pivotally supported on the bearing portion 15 so that the lower end portion is supported. The rope 7 is connected via a bracket (swinging operation tool) 18 to a shaft 17 that is pivotally connected to the upper end portion of the lower panel 3b and that connects the bending portions of the swinging arm 16. (See FIGS. 2 and 3).

  Further, the shaft 17 connecting the bent portions of the swing arm 16 causes the bracket 18 and the lower center of gravity G to be connected between the bent portion of the swing arm 16 and the connecting portion 20 of the lower panel 3b as shown in FIG. It is formed so as to be offset from the perpendicular line 21 from the center of the bearing portion 15 provided on the flat surface of the slider 13 to the right in FIG. 3 (in the direction away from the back surface of the upper panel 3a). desirable.

In FIG. 22, reference numeral 23 denotes a lower limit restricting stopper for the slider 13 formed near the lower end of the guide rail 14, and reference numeral 23 denotes a movement restricting plate.
Thus, when the center of gravity G is formed at a position deviating from the perpendicular line 21 from the center of the bearing portion 15, after the slider 13 is received by the lower limit regulating stopper 22, the rope 7 is further fed out. Then, the center of gravity G is rotated clockwise in the drawing so as to be positioned on the vertical line from the center of the bearing portion 15 of the swing arm 16 so that the lower panel 3b is positioned on the surface side of the upper panel 3a. Extruded.

Next, the operation of the stage apparatus 1 composed of a plurality of panels 3a and 3b according to the present invention formed as described above will be described.
First, when used as a stage background, the two panels 3a and 3b are arranged up and down, and the upper and lower panels 3a and 3b provided with patterns and sets on the surface are used with the surfaces thereof being substantially flush with each other. (See figure).

Next, when changing the background used so far to change the scene, the motor 5 is driven to rotate the reel 8b to wind up the rope 7.
When the rope 7 is wound up from the state shown in FIG. 4A, the upper end portion of the swing arm 16 received by the bearing portion 15 due to the sliding resistance between the guide rail 14 and the slider 13 is rotated counterclockwise. It rotates in the direction (see FIGS. 3 and 4A).
Thus, the lower panel 3b is moved to the right in the figure (the back side of the upper panel 3a) by the counterclockwise rotation of the swing arm 16.

After that, when the rope 7 is continuously wound up, the slider 13 is guided and raised by the guide rail 14, so that the lower panel 3b rises on the back side of the upper panel 3a as shown in FIG. Go.
When the detection device (not shown) detects that the lower panel 3b is raised, the rope 6 is wound up at the same speed as the rope 7, so that the upper and lower panels 3a and 3b are arranged in front and back, as shown in FIG. And it raises and accommodates in the upper accommodation position shown by the dashed-two dotted line in FIG. 4 (B).

As a detection device for detecting that the lower panel 3b is raised, a limit switch is provided at the upper end portion of the guide rail 14, and the limit switch is operated by raising the slider 13, and the amount of winding of the rope 6 is detected. Then, the upper panel 3a can be raised when a predetermined winding amount is reached.
In order to set the upper and lower panels 3a and 3b to the use position lowered from the storage position, the upper and lower panels 3a and 3b at the storage position are moved down at the same speed by driving the motor, and the upper panel 3a is predetermined. When the position becomes, the feeding of the rope 6 is stopped.

When the rope 7 is fed out as it is, the slider 13 is guided by the guide rail 14 and the lower panel 3b is lowered.
After the slider 13 is received by the lower limit restricting stopper 22 provided on the guide rail 14 and the lowering of the lower panel 3b is stopped, when the rope 7 is continuously extended, the swing arm 16 is moved to the bearing portion 15. It rotates in the clockwise direction with the received upper end portion as the center of rotation (see FIG. 3).

By the pivoting of the swing arm 16 in the clockwise direction, the lower panel 3b is moved to the left in the figure (the surface side of the upper panel 3a), and the surface of the lower panel 3b is moved to the movement restricting plate 23. When contacted, the upper and lower panels 3a and 3b are flush with each other.
When the detection device detects that the surfaces of the upper and lower panels 3a and 3b are flush with each other and stops the feeding of the strips, the descending process of the panels 3a and 3b is completed.

The stage apparatus 1 composed of a plurality of panels according to this example is obtained by changing the swing arm 16 portion of the moving mechanism in the first embodiment as shown in FIG.
That is, the bearing portion 15 is provided on the flat surface of the slider 13 that slides on the guide rail 14 provided on the back surface of the upper panel 3a, and the swing arm 16 is formed in a slanted ball or L-shape as in the first embodiment. A pivot shaft 25 that connects the upper end portions of the swing arm 16 arranged side by side on the lower surface of the lower panel 3b is pivotally supported by the bearing portion 15, and the lower end portion of the swing arm 16 is moved downward. The cable 3 is connected to the upper end portion of the panel 3b so as to be rotatable, and the rope 7 is connected to the upper end of an operation bracket (operation tool) 18 attached to the rotation shaft 25 obliquely upward at the rear. Is.

In this example, when storing, the lower bracket 3b moves to the back side of the upper panel 3a by swinging the operation bracket 18 upward by the rise of the rope 7.
The movement of the lower panel 3b is based on the lever principle, and there is an advantage that the lower panel 3b can be moved with a lighter force as the length of the operation bracket 18 is longer.
Also in this example, the operating bracket 18 and the lower center of gravity G are connected to the connecting portion 20 of the lower panel 3b by the shaft 17 connecting the bent portions of the swing arm 16 as shown in FIG. It is desirable to form at a position deviating to the right as shown in the figure from the perpendicular line 21 from the center of the bearing portion 15 provided on the flat surface. Other configurations are the same as those of the first embodiment.

Thus, when the center of gravity G is formed at a position deviating from the perpendicular line 21 from the center of the bearing portion 15, the ridge 7 is further extended even after the slider is received by the 13 lower limit restricting stopper 22. Then, the swing arm 16 is rotated in the clockwise direction in the drawing so that the center of gravity G is positioned on the vertical line 21 and the lower panel 3b is pushed out to be positioned on the surface side of the upper panel 3a.
In each of the above-described embodiments, the upper and lower panels are provided. However, the present invention is not limited to this, and it goes without saying that three or more panels can be provided.
