Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pool elevating floor support device for firmly and reliably holding the elevating floor of the pool at a desired height.

[Prior art and its problems]

In recent years, with the rise in awareness of health management, swimming has become popular as a sport that can be practiced by everyone from infants to the elderly. so that it can be used for personal use or for infants,
Various devices have been proposed that can adjust the depth to an arbitrary depth.

An example of this will be explained based on Fig. 5.Floor 2 of pool l
is formed thick, and a plurality of air supply/discharge passages 3 are provided on this floor 2, and a large number of bellows-type supports 4 are attached to each of these air supply/discharge passages 3 to support the IIf moving bed 5. death,
By connecting each of the air supply/discharge passages 3 to a compressor 6, compressed air is supplied from the compressor 6 to the bellows type support 4 to adjust the height of the movable floor 5. Lifting floor devices for swimming pools are known.

However, in the above-mentioned conventional pool elevating floor device, since the supports supporting the movable floor 5 are bellows-type supports 4 that are expanded and contracted by compressed air, it is difficult to lower the movable floor 5 to the highest position. , due to the presence of the bellows type support 4, it is inevitably located at a distance from the floor 2, creating a so-called dead space.
The problem was that the pool opening could not be used effectively.

That is, if a dead space occurs, the floor 2 of the pool 1 must be formed as deep as possible to accommodate the put space, which increases the installation cost, and This had many problems, including wasting water and increasing running costs.

This invention was devised in view of the current situation, and its purpose is to lower the elevating floor fitted into the opening of the pool to the floor of the pool; Therefore, it is an object of the present invention to provide an elevating floor support device for a swimming pool that does not take up space and can significantly reduce construction costs and running costs.

[Structure to solve the problem]

In order to achieve the above object [1], in the present invention, a space is formed between the bottom surface of the pool opening and the foundation surface, and a space is fitted into the pool opening so that it can be raised and lowered. Assuming that the pool lift floor support device is

[Effect]

Therefore, in the pool elevating floor support device according to the present invention, in order to lower the elevating floor of the pool to the pool floor, the screw jack for elevating and supporting the elevating floor is moved to the bottom of the pool opening. It is characterized by being disposed in a space formed between the base and the base surface.

(Example) Hereinafter, the present invention will be described in detail based on an example shown in the accompanying drawings.

As shown in FIGS. 1 and 2, the elevating floor support device according to this embodiment is installed in the pool 1. ．． The elevating floor 1O is provided, a screw jack 20 is provided below the elevating floor 1O, and a drive source 30 for extending and retracting the screw jack 20 is configured.

The elevating floor 10 is fitted into the opening 1a of the pool 1 so as to be able to be raised and lowered, and is made by arranging a large number of cylindrical aluminum or stainless steel flooring materials 11 in parallel. By connecting these, the planar opening area of the pool 1 and the approximately concave floor area are formed.

Of course, an appropriate reinforcing member 12 is provided on the lower surface of each flooring material 11.
is fixed.

Incidentally, the required lengths of the flooring material 11 are filled with air, and both ends are sealed with lids so as to maintain buoyancy in water. The amount of air to be filled is set to "zero" by canceling out the entire weight of the elevating floor io in the water and the buoyancy force.

The elevating floor 10 configured as described in 1- below is fitted into the opening 1a of the fool 1, and the screw jack 2
It is configured to be raised and lowered in one direction along the inner wall surface 1b of the pool I.

As shown in FIG. 21A and FIG. There are multiple books placed in each area.

The end of the piston rod 1-21 is connected to the reinforcing member 12 provided on the lower surface of the elevator floor 10 via a flaket 22, and the t end of the casing 23 is connected to the base floor 1d. It is fixed in an upright position.

In addition, the piston rod 21 of the screw jack 20 is
As shown in FIG. 3, it is screwed onto a bearing member 24 fixed to the pool bottom surface 1c, and a sealing member 25 provided on the bearing member 24 prevents water from leaking in the pool. A bevel gear 31 rotated by a drive source 30 meshes with the piston rod 21 held in this manner.

As shown in FIG. 3, the bevel gear 31 is attached to the tip of a drive shaft 32, and the drive shaft 32 is connected to a drive motor 33 such as an electric motor or a hydraulic motor so as to be rotatable in forward and reverse directions. has been done. Of course, the drive motor 33 is equipped with a reduction gear (not shown) or a reduction gear of a required ratio.

Further, as shown in FIG. 3, the -h drive motor 33 is disposed inside the pool inner wall surface ib, and the drive shaft 32 extends above the pool bottom surface 1c through the inner wall surface 1b. The drive shaft 32 is supported in a liquid-tight manner by a seal member 34 fixed to the inner wall surface 1b to prevent water from leaking from the pool.

The screw jack 20 and drive source 30 configured as described above are driven and controlled by a control circuit 40 so as to maintain the elevating floor 10 at a horizontal level.

This control circuit 40 can drive and control a plurality of devices to appropriately resist a known device that maintains the water level. An example of this is shown in FIG. 4. The control circuit 40 includes an encoder 41, and the encoder 41 includes:
Switches 42 and 43 for instructing the expansion and contraction strokes of each screw jack 20 are connected, and the encoder 41 is configured to output a drive signal to the drive motor 33, and the control circuit 40, the IJ ti! of the M lowering floor 10 which is raised and lowered by the screw jack 20 is shown. A signal from a sensor 44 that detects the position is input.

These sensors 44 are arranged at predetermined intervals along the height direction of each pool inner wall surface 1b facing each other, and the sensors 44 arranged at the facing positions detect whether the horizontal level of the elevating floor 10 is be done.

Therefore, for example, when the extension instruction switch 42 is turned on, the rotation of each drive motor 33 is synchronously transmitted to each bevel gear 31 via the drive shaft 32, and the rotation of the bevel gear 31 causes each piston rod to 21 rises synchronously, and the elevating floor 10 is adjusted to a desired height position. When the sensor 44 detects that the elevating floor 10 has been raised to a desired height position, that signal is input to the encoder 41, and the encoder 41 stops the drive motor 33. Of course, if the elevating floor IO is not maintained at a horizontal level, one of the sensors 44 facing the other side will not operate.
The encoder 41 finely controls the screw jack 20 corresponding to the sensor 44 that is not activated to extend and operate until the elevating floor 10 is at a horizontal level, that is, the sensor 44 that is not activated is activated.

Also, contrary to the above, when lowering the elevating floor 10,
All you have to do is operate the contraction instruction switch 43. At this time, the screw jack 20 is contracted, and after the screw jack 20 is contracted and the elevating floor 10 is lowered to the desired height position, the above-mentioned Similarly, drive motor 3
In addition to being stopped, fine adjustment control is also performed.
