Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable floor pool in which the floor of the pool can be moved to change the water depth of the pool.

[0002]

2. Description of the Related Art FIG. 3 shows a conventional movable floor pool in which the floor of the pool moves up and down so as to have an appropriate depth according to the height of the pool user.

As shown in FIG. 3, the bottom 50 of the pool 50 is
Hydraulic cylinders 51 are embedded in a plurality of cylindrical pits 50b formed in a, respectively, and the tip ends of rods 51a of these hydraulic cylinders 51 have a floor plate 52 in which a floor material 52a is reinforced by a reinforcing frame 52b. Each is connected to the bottom surface. A hydraulic pressure generation unit 53 is connected to these hydraulic cylinders 51 via a hydraulic pressure distribution block 54.

That is, the water pressure generating unit 53 is operated to vertically move the rod 51a of the water pressure cylinder 51, thereby vertically moving the movable floor 52 and adjusting the water depth of the pool 50.

[0005]

In the movable floor pool as described above, the hydraulic cylinder 51 is installed in the bottom portion 50 of the pool 50.
Since it is buried in the pit 50b formed in a, a considerable depth is required to install the movable floor pool. For this reason, it is very difficult to obtain a predetermined depth even if an attempt is made to install a movable floor pool on a middle floor of a building such as a hotel or a sports facility. Further, since the hydraulic cylinder 51 requiring inspection is buried in the pit 50b below the movable floor 52, maintenance and inspection of the hydraulic cylinder 51 and repair at the time of failure will be very troublesome.

[0006]

In order to solve the above-mentioned problems, the present invention adjusts a floor plate which is provided inside a pool and produces a buoyancy force against the liquid in the pool, and a floating position of the floor plate. That is, the movable floor pool was configured by including the floor board floating adjusting means.

[0007]

In the movable floor pool having the above-mentioned structure, the floor plate produces a buoyancy against the liquid in the pool. Therefore, the effective depth of the pool can be easily set by adjusting the floating position of the floor plate by the floor plate floating adjusting means. .

[0008]

EXAMPLE An example of a movable floor pool according to the present invention will be described with reference to FIGS. 1 is a plan view thereof, and FIG. 2 is a sectional view taken along the line II-II of FIG.

As shown in these figures, a plurality of motors 11 capable of normal and reverse rotation are provided in a power chamber 22 near a pool 21 formed in a concave shape. The output shaft 11a of the motor 11 is a power distributor 1 that distributes power in two directions.
It is connected to each of the two input parts. The output shafts 12a and 12b of the power distributor 12 are connected to the input side of the bevel gear box 13, respectively. Bottom 2 of pool 21
1a has one end side pivotally supported by a seal bearing 14 inserted into a partition wall surface 21b between the pool 21 and the power chamber 22, and the other end side having a bottom portion 21 near a wall surface 21c facing the partition wall surface 21b.
A plurality of rotating shafts 16 pivotally supported by bearings 15 installed in a are provided. One end side of these rotary shafts 16 penetrates the partition wall surface 21b by a seal bearing 14 and is connected to an output shaft 13a of the bevel gear box 13 via a joint 17.

A plurality of cylindrical drums 18 around which the filament is wound are provided on the rotary shafts 16 coaxially with the rotary shafts 16 at predetermined intervals along the axis of the rotary shaft 16. One end side of a wire rope 19, which is a filament made of stainless steel, high-strength resin fiber, or the like, is fixed to the peripheral surfaces of these drums 18, respectively. The other ends of the wire ropes 19 are fixed to the lower surfaces of the floor plates 10 arranged in the pool 21 in a direction intersecting the axis of the rotary shaft 16 so as to cover the bottom 21a of the pool 21. These floor plates 10 are made of a fluid such as closed-cell urethane foam on the lower surface of a flat plate-like floor material 10a such as a steel plate such as stainless steel, a resin such as hard polyvinyl chloride, or a composite material such as fiber reinforced resin. A buoyant member 10b that produces a buoyant force greater than or equal to a predetermined load force is attached to a certain water and is reinforced by a lightweight member frame 10c.

The motor 11, the seal bearing 14, the bearing 15, the rotary shaft 16, the drum 18, the wire rope 19 and the like constitute the floor plate levitation adjusting means in this embodiment.

Such a movable floor pool may be used as follows. The wire rope 19 is wound around the drum 18, that is, the floorboard 1 is close to the bottom 21a of the pool 21, water is injected into the pool 21, and the floorboard 10 rises together with the water surface of the pool 21. 11 is driven and the wire rope 19 is sent out. When the floor plate 10 has risen to a predetermined position, the driving of the motor 11 is stopped while continuing water injection. Stop pouring when the water surface reaches the specified position. Thereby, the water depth of the pool 21 is easily set to an arbitrary depth.

Further, when the floorboards 10 have been poured into the pool 21, the respective motors 11 are driven so as to move the floorboards 10 separately, and when the floorboards 10 reach the predetermined positions, the motors 11 are moved. You can stop each. As a result, the water in the pool 21 greatly swings,
The water surface can be adjusted while preventing the water from undulating as much as possible.

On the other hand, when exchanging water in the pool 21, the water is discharged from the pool 21, and when the water surface reaches the position of the floor plate 10, the motor 11 is driven so that the floor plate 10 descends together with the water surface. Then, the wire rope 19 is wound up. As a result, water is easily discharged from the pool 21, and the water in the pool 21 is easily replaced by raising the floor plate 10 while pouring water as described above.

Therefore, the movable floor pool can be installed without providing a pit or the like on the bottom 21a of the pool 21, and the bearing 15, the rotary shaft 16, the drum 18,
As described above, since only the members that are almost unnecessary for inspection are provided on the bottom portion 21a of the pool 21, maintenance and inspection are very easy.

In the present embodiment, the procedure for raising and lowering the floorboard 10 has been described as above, but the present invention is not limited to this, and it may be adjusted depending on the positions of the water supply port and the water discharge port of the pool, the water supply / drainage capacity of the pool, and the like. Then, the floor board may be moved up and down so that the filaments such as the wire rope do not come loose. In this embodiment, the plurality of floor plates 10 are arranged so as to cover the bottom portion 21a of the pool 21, but one floor plate may be arranged so as to cover the bottom portion 21a of the pool 21. In this embodiment, a plurality of motors 11
However, each rotary shaft may be connected to one motor via a clutch.

In addition, an auxiliary buoyancy member may be detachably provided on the upper surface of the floor plate in accordance with the usage conditions such as water depth and the number of people used. If this auxiliary buoyancy member is formed in a staircase type, it is possible to enter and exit the pool. It will be very easy. Depending on the shape and size of the floor plate, if a plurality of small-diameter holes that connect the upper surface and the lower surface of the floor plate are provided, the waviness of the water surface that occurs when the floor plate moves up and down can be reduced, and the floor plate can be easily moved up and down. If there is a large disparity in height and age of the users, if the drum provided closer to the other end of the rotary shaft has a larger diameter than the drum provided closer to the other end, By simply driving the motor, the floor plate is inclined so that the water depth becomes shallower on the other end side than on the one end side of the rotating shaft, and it can be used by people of various heights and ages at the same time.

[0018]

As described above, in the movable floor pool according to the present invention, since the floor plate causes buoyancy with respect to the liquid in the pool, the floor plate floating adjustment means only adjusts the floating position of the floor plate to make the pool effective. Since the depth can be easily set, the member provided at the bottom of the pool has only a simple structure that requires almost no inspection, and maintenance and inspection of the movable floor pool becomes very easy. In addition, there is no need to provide a pit at the bottom of the pool, and the depth required to set up a movable floor pool is greatly reduced, so not only can a movable floor pool be easily installed on the middle floors of a building, Installation costs are also reduced.
