Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for tilting a stage and the floor around it at any angle without any gaps.

[Prior Art] The stage and surrounding floor of a theater where plays and various shows are performed can be tilted depending on the scene and purpose, thereby creating a sense of perspective on the stage. The performance effect can be enhanced. Moreover, it becomes easy to use it as a stage, audience seats, orchestra pit, etc.

Conventionally, the stage floor was divided into relatively large sections, and as shown in Figure 6, the floor a of each section was covered with hydraulic jacks b from one side.
etc., to change the inclination angle.

[Problems to be solved by the invention] However, if the floor surface a of a relatively large section is made of a single plate, the thickness will be increased to maintain rigidity, and the weight will also increase. Capacity and driving energy become significantly large.

Furthermore, the setting of stage props was limited only by the slope of the single-plate floor surface a of the large section.

Furthermore, when the floor surface a is tilted, the adjacent floor surface a is tilted as shown in FIG.
′ and the edge C will interfere, so each floor surface a, a
' must have a large gap, especially on the floor surfaces a and a.
If ' was thick, the gap would become significantly larger, which was dangerous.

c. Means for Solving Problems] The present invention aims to solve the problems of the conventional art and to enable floor surfaces partitioned into appropriate sections to be tilted and arranged at arbitrary angles without gaps. A stage floor tilting device characterized in that a floor of a required size is mounted on a support bridge below the floor so that it can tilt and the support point can be moved. be.

[Function] The floor surface supported by the sliding body on the support bridge is tilted and fixed at any angle by the tilting tool.

By moving the slide body using the fulcrum horizontal moving device, the fulcrum and the floor surface are moved horizontally, and the gap between the edges of the adjacent floor surfaces is closed.

[Example].

Embodiments of the present invention will be described below with reference to the drawings.

1 to 4 show an embodiment of the present invention, in which a support frame 3 consisting of four pillars 2 is attached to a fixed frame 1 assembled below the main stage or its surroundings so as to be movable up and down. A pinion 7 rotated by a DC motor 5 and a speed reducer 6 installed on the fixed frame 1 is engaged with a rack 4 provided on the inner surface of each column 2, so that the support frame 3 can be raised or lowered to an arbitrary height. That's how it is.

Rails 9 are laid in parallel on each cross member 8 at the top of the support frame 3, and support rollers 10 are respectively arranged on each rail 9,
A rod 12 of a bear lock cylinder 11 having a holding force for horizontal movement of a fulcrum having one end fixed to the top of the support frame 3.
The tips of the rods 10 are connected to each of the marking rollers 10, and each marking roller IO can be moved on each of the rails 9 by the protrusion of each rod 12.

Support brackets I4 are provided at both ends of the central part of the back side of the floor surface 13 for small pressing divided into required sizes, and the lower end of each holding bracket 14 is attached to each of the pressing rollers 10.
5, etc., and each of the writing rollers 10 and the floor surface 13
Bear lock cylinders 16 having a holding force for tilting the floor surface are connected between the required positions on the back side of the The floor surface 13 is designed to be tiltable.

Further, a plurality of stage floor tilting devices 18 configured in this manner are installed in front, rear, left and right so that the floor 13 tilts in the same direction to form a stage approach 19.

By keeping the height of each support frame 3 constant and holding each floor surface 13 horizontally with a bear lock cylinder 16, a horizontal floor surface of any height with no gaps is formed, and as an extension of the main stage. can be used as audience seats and orchestra pit.

When tilting the stage approach 19 entirely in the same direction,
In the horizontal state, each floor surface 13 cannot be tilted because the 19° edge of each adjacent floor surface interferes with each other, so first, each support frame 3 is connected to the rack gear 4, rack pinion 7, DC motor 5,
The speed reducer 6 raises each to a predetermined height in stages,
Next, the rods 17 of each bear lock cylinder 16 are
The length protrudes and each floor surface 13 is inclined at approximately the same angle.

If each floor surface 13 is simply inclined, as the angle of inclination increases, the gap between the edges of the adjacent floor surfaces 13' will become larger. By pulling in the respective required strokes, the rear floor surface 13 is moved forward and the gap between the above-mentioned ledges is eliminated. By sequentially performing the same operation on the rear floor surface 13, an arbitrary angle of inclination with no gap is formed near the stage. Here, the rear floor surface I3 is the distance sent forward, that is, the rod 1
The amount of retraction of 2 increases.

In the above, the pair of bear lock cylinders 11
and 16 are each driven in synchronization and have self-holding power, so that they can sufficiently support the load applied to each floor surface 13, and a stable inclined or horizontal floor surface 13 can be obtained.

FIG. 5 shows another embodiment of the present invention, in which a rotating shaft 20 is pivotally supported on one side of the top of the support frame 3, and a lever 21 is attached to the rotating shaft 20, in a configuration substantially similar to that of the previous embodiment. Attach to prevent rotation: A support bracket 22 provided on the back side of the floor surface 13 is pivotally attached to the tip of the lever 21 by a pin 23, and the output of the sprocket 24 attached to the rotating shaft 20 and the motor 25 with a reducer Sprocket 27 fixed to shaft 26
The chain 28 is hung endlessly. A rotary shaft 29 is pivotally supported on the other side of the top of the support frame 3, and a guide lever 30 having a U-shaped cross section is attached to the rotary shaft 29 so that the guide groove 31 faces to the side so as not to rotate. A roller 3 is attached to the tip of the tilting bracket 33 provided on the back side of the surface 13.
4 is attached by a pin 35, and the roller 34 is fitted into the guide groove 31 of the guide lever 30. Further, a chain 40 is endlessly hooked around the sprocket 26 attached to the rotating shaft 29 and the sprocket 39 fixed to the output shaft 38 of the motor 37 with a reduction gear. 41.42 in the figure
indicates a stopper, and 43 indicates a buffer material.

In the case of this embodiment, when the sprocket 36 is rotated via the chain 40 by driving the motor 37 with a speed reducer, the rotating shaft 29 and the guide lever 30 rotate clockwise in FIG. 5, and the roller 34 is pushed up. Floor surface 1
3 is tilted at a predetermined angle.

When closing the gap between the hems, the sprocket 2 can be closed via the chain 28 by driving the motor 25 with a speed reducer.
4, the rotating shaft 20 and lever 21 rotate counterclockwise in FIG. 5, and the floor surface 13 is moved forward to close the gap between the edges.

It should be noted that the stage floor tilting device of the present invention is not limited to the above-described embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.

[Effects of the Invention] As described above, according to the stage floor tilting device of the present invention, the floor surface is mounted on the support frame so that it can be tilted and the support point can be moved. Alternatively, it can be partially tilted at any angle, and can be tilted in two directions. Moreover, it is safe because the gaps between the adjacent floor surfaces can be properly closed, and the minimum slope is possible. It exhibits various excellent effects such as being able to quickly change the inclination angle of the stage using equipment and power.
