Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an underwater stage that is installed underwater in a pool or the like and allows performers to emerge from the water onto the surface of the water.

[Conventional technology]

It is well known that a stage that can be raised and lowered is provided underwater in a pool or the like. This well-known stage is intended for use by performers wearing swimsuits and other clothes that can get wet.

[Problem that the invention seeks to solve]

As mentioned above, on conventional stages, performers need to wear clothing that they don't mind getting wet, and in order to place performers wearing normal clothes who would be in trouble if they get wet, onto the stage that appears on the surface of the water. In this case, a bridge must be built from the edge of the pool to the stage, or the performers must be transported onto the stage by boat, which is time-consuming and creates problems in terms of production.

[Means for solving problems]

In order to solve the above problems, this invention provides an opening in a part of the bottom of the water, and water flows into the opening between the cylindrical waterproof fence attached to the opening so that it can be raised and lowered and the periphery of the opening. A watertight maintenance means is provided to prevent this from occurring, and a stage is provided within the fence that is raised and lowered by an appropriate driving means, and a watertight maintenance means is provided to maintain watertightness between the stage and the fence under the condition that the stage is fitted into the fence. A holding means is provided, and a boarding entrance is provided at the bottom of the water for performers to get onto the stage under the conditions that the fence is in the raised position and the stage is in the lowered position.

[Effect]

This invention has the above configuration, and when the stage is not in use, both the waterproof fence and the stage are lowered to the bottom of the water, and the upper edge of the fence and the top surface of the stage are kept substantially aligned with the bottom of the water.

At this time, the watertight retaining means prevents water from flowing between the waterproof fence and the opening and between the waterproof fence and the stage, so that water does not flow into the entrance below the water bottom.

Next, raise the waterproof fence and the stage at the same time, stop the waterproof fence when the upper edge of the waterproof fence and the top of the stage are slightly above the water level, and then lower only the stage. Since they couldn't get in, we lowered the stage to the lowest position and had the performers board the stage through the entrance.

After the performers are placed on the stage in this way, when the stage is raised, the performers who are not wet will appear above the water.

In addition, when the waterproof fence and stage are raised as described above, if the upper edge of the waterproof fence is slightly below the water surface, when the waterproof fence is lowered, water will flow down from the periphery of the waterproof fence. A film is formed. In this case, a movable waterproof tunnel will be installed at the entrance to prevent performers from getting wet as they board the stage. Note that the lowering of the stage is performed by the reverse procedure of raising the stage.

〔Example〕

In each figure, 1 is the bottom of the pool, its lower part is the chamber 2, and 3 is its floor. 4 is an opening provided in the water bottom 1, and a waterproof fence 5 that can be raised and lowered is provided within this opening 4. The waterproof fence 5 has a cylindrical shape when the opening 4 is circular, and a watertight retaining means 7 is provided between the outside thereof and the periphery of the opening 4.

In this embodiment, a bellows-shaped member made of water-resistant rubber is used as the watertight holding means 7, and its upper end is fixed to the outer periphery of the upper end of the fence 5 in a watertight manner, and its lower end is fixed to the periphery of the opening 4 in a watertight manner.

A plurality of brackets are provided on the outer periphery of the upper end and the outer periphery near the lower end of the fence 5, and the upper and lower ends of a plurality of vertical guide rails 8 are fixed to each of the upper and lower brackets, and these are inserted into the guide holes 9 provided around the opening 4. Insert freely. The guide rail 8 is also slidably inserted into holes in a plurality of guide pieces 10 on the outside of the bellows-shaped watertight retaining means 7.

Reference numeral 12 denotes a peripheral wall of the opening 4, and a fence fixing means 1 is attached to the lower part of the peripheral wall of the opening 4.
3 will be provided. This fixing means consists of a locking cylinder operated by hydraulic pressure, etc., and a lock pin that moves forward and backward by this cylinder, and when the waterproof fence 5 rises to a predetermined height, it engages with the retaining part on the outside and fixes it. It is.

Reference numeral 15 denotes a machine room provided below the opening 4, which houses a driving means 17 for the stage 16. The stage 16 has a disc shape when the opening 4 is circular, and is sized to fit into the fence 5 with some clearance, and has a peripheral wall 18 around its lower part. A ring-shaped rubber gasket is provided as a watertight retaining means 20 on a flange 19 on the outer periphery of the lower end of the peripheral wall 18, and when this gasket contacts the fence 5, the watertightness between the fence 5 and the stage is maintained.

The driving means 17 is of a rack and pinion type. That is, a plurality of (eight in the figure) columns 22 are fixed to the lower part of the stage 16, and a rack gear 23 is attached to the outside of each column 22.
A pinion gear 2 that meshes with this rack gear 23 is provided.
4 in the forward and reverse directions.

Reference numeral 25 in FIG. 1 is the floor of the machine room 15, and a plurality of vertical holes 26 into which the above-mentioned supports 22 fit are provided in this floor.

Reference numeral 27 in FIGS. 1 and 2 is an annular waterproof wall provided on the floor 25, and a frame 28 is provided on the floor 25 inside the wall.

Reference numeral 29 in FIGS. 1 and 2 denotes a plurality of drive shafts rotatably attached to the frame 28, and the pinion gear 24 is fixed to each shaft 29.

A submersible lifting motor 30 and a general lifting motor 31 are provided in the frame 28, and the shafts of both motors are connected to the input shaft of a central reduction gear 32, and the output shaft of this reduction gear is connected to the input shaft of four gear boxes 33. The output shaft of each gearbox is connected to the front drive wheel 29.

Further, a plurality of guide rollers 34 are attached to the frame 28, as shown in FIGS. 1 and 2, to support the back surface of each support column 22.

Reference numeral 35 denotes a water blocking wall that blocks the chamber 2 from the opening 4, and the outside of this blocking wall 35, that is, the opening 4 side becomes the entrance 36. Therefore, a part of the blocking wall 35 is provided with an entrance/exit (not shown) having a waterproof door so that the passenger can go back and forth between the room 2 and the entrance 36.

38 in Figure 1 is a waterproof tunnel that looks like a downward U-shaped frame covered with a waterproof sheet, and wheels are installed at the bottom so that it can be moved freely.

Reference numeral 39 in FIG. 1 is a drain groove provided around the floor 25 of the machine room 15, and water flowing into the drain groove 38 is appropriately discharged through a drain pipe 40.

Next, to explain the operation of the above embodiment, FIG. 3 shows a state in which the stage is lowered, and at this time, the stage 16
The upper surface is at approximately the same level as the water bottom 1 of the pool, the waterproof fence 5 also rests on the watertight retaining means 20 of the flange 19 at the lower part of the stage 16, and the upper end of the fence 5 is approximately at the same level as the upper surface of the stage 16.

Next, start the motors 30 and 31 to drive each pinion gear 2.
4 is rotated forward, each support column 22 is rotated through the rack gear 23.
rises, raising the stage 16, and at this time, the waterproof fence 5 also rises.

In this way, under the condition that the stage 16 and the waterproof fence 5 are raised to a height that almost corresponds to the water surface as shown in FIG.
0.31, and the fence 5 is fixed by the fence fixing means 13.

Then, by reversing only the motor 31, the pinion gear 24
When the stage 16 is reversed, only the stage 16 is lowered, and when the upper surface of the stage 16 becomes substantially flush with the upper surface of the floor 3, the motor 31 is stopped and the stage 16 is fixed, resulting in the state shown in FIG.

At this time, if the upper edge of the fence 5 is even slightly lower than the water level of the pool, the water in the pool overflows from the upper edge of the fence 5 and forms a water film along the inner surface of the fence 5, causing it to flow.
6, flows into the drain groove 39 at the bottom of the machine room 15, and is discharged from the drain pipe 40.

Further, at this time, since the entrance 36 is opened, the performers who have been waiting in the room 2 board the stage 16 through the entrance 36 using the waterproof door of the water-blocking wall 35. However, when the water film passes through the area where the water is flowing down, the user gets wet, so if the waterproof tunnel 38 is advanced into the water film and passes through there, there is no risk of getting wet.

Further, if the upper end of the waterproof fence 5 protrudes B above the water surface, water will not overflow, so there is no need for the waterproof tunnel 38.

After confirming that all the performers are on the stage 16 as described above, only the motor 31 is started and the pinion gear 24 is rotated in the normal direction, and the stage 16 on which the performers are placed appears on the water surface.

The reason why two motors 30 and 31 are used to raise the stage 16 in the lowered position along with the fence 5 due to the above action is that a large water pressure is applied on the stage 16, and after raising the fence 5, Since there is no influence of water pressure, the stage 16 can be moved up and down with only one motor 31.

When the performance on the stage 16 is finished, the stage 16 is lowered by the reverse rotation of the motor 31 and the performers are returned to the room 2 through the entrance 36.Then, the stage 16 is raised and the watertight retaining means on the flange 1S at the lower part of the stage 16 is raised. 20 is brought into close contact with the lower end of the waterproof fence 5, and the fence 5 is fixed by the fence fixing means 13.
After releasing the fixation, the stage 16 and fence 5 are lowered into the water by reversing the two motors 30 and 31.
Return to the state shown in the figure.

The structure of the watertight maintenance means 7.20 and the structure of the drive means 17 of the stage 16 described above are merely examples, and the waterproof fence 5 can also be moved up and down by a drive means separate from the stage 16.

Further, although the embodiment shows a case in which the stage 16 is raised to near the water surface, it is also easy to raise the stage 16 even higher than the water surface.

〔effect〕

As described above, this invention allows the stage located at the bottom of the water to rise to the water surface and allow performers to perform various acts on the stage, but in the case of this invention, the stage is simply raised from the bottom of the water. Instead, a watertight maintenance means is provided between a cylindrical waterproof fence that is movably attached to an opening provided in a part of the bottom of the water and the periphery of the opening, and that prevents water from flowing into the opening. is provided with a stage that can be raised and lowered by a suitable drive means, and between this stage and the fence there is provided a watertight retaining means that maintains watertightness between the two under the condition that the stage is fitted into the fence, so that the stage can be lowered together with the waterproof fence. Water does not flow into the entrance under the water either when the stage is raised together with the waterproof fence, or when the stage is lowered with the waterproof fence raised.

Therefore, the performers board the stage through the entrance at the bottom of the water without getting wet and rise directly above the water surface, resulting in an effect that is completely different from that of conventional water stages.
