Abstract

PROBLEM TO BE SOLVED: To hold a swimming pool floor suspendedly on the wire drive system and simplify the structure of the pool floor arranged as capable of elevating and sinking by removably mounting a heavy object at each of the four corners of the pool floor, and curving the central part of the floor upward with respect to the peripheries by the buoyancy. SOLUTION: The floor 10 of a swimming pool 1 is formed so that the floor is elevated and sunk by a wire rope 20 along the wall surfaces 1b of the pool 1. The pool floor 10 is configured so that a number of floor material pieces 11 in an appropriate size are coupled together, wherein the floor pieces 11 are formed with a central panel body so that the underwater buoyancy is made greater than the specific gravity of the water. A heavy object 3 made of metal plate having a large thickness is removably installed on the undersurface of the floor material 11 at each corner of the pool floor 10. The corner parts subside and the central part of the floor 10 is curved upward, and it is practicable to effectively and certainly prevent the central part from deflecting even though an elevating/sinking means for the floor 10 is embodied as a suspending means such of wire drive type etc. As a result, a sufficient rigidity is ensured even though the floor structure is simplified.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor device for a pool or the like which can increase the load bearing capacity of a pool floor or the like which can be raised and lowered.

[0002]

2. Description of the Related Art In recent years, with increasing awareness of health management, swimming has become popular as a sport that can be carried out from infants to old people, and therefore, pools formed for adults to swim in pools formed for adults or In many cases, the pool floor can be raised and lowered so that it can be used for infants.

There have been various proposals for raising and lowering the pool floor, but in many cases, at least a corner of the pool floor is hung from above, or
Generally, the floor of the pool can be raised and lowered by supporting it from below.

As means for suspending the pool floor from above, for example, wire ropes connected to the corners of the pool floor, a plurality of pulleys on which the wire ropes are suspended, and the wire ropes are wound or unwound. There is a wire drive system that includes a drum, a drive device that drives the drum, and a control device that controls the drive device. Further, there is a chain drive system in which the wire rope is replaced by a chain.

As means for supporting the pool floor from below, for example, a plurality of screw jacks standing upright including the corners of the pool floor, and wiring connected to the plurality of screw jacks, There is a jack drive system including a controller connected to the wiring and controlling expansion and contraction of the screw jack.

In the cylinder drive system in which the screw jack is replaced by a fluid pressure cylinder, the wiring is a pipe, and a hydraulic pressure supply / discharge source as a drive source is connected to the pipe.
The control device is connected to the hydraulic pressure supply / discharge source.

By the way, when the lifting means for the pool floor is the former suspension means, it becomes virtually impossible to suspend the central portion of the pool floor, so that the central portion of the pool floor is easily bent. In the extreme case, there is a problem that the depth of the corner portion and the depth of the central portion of the pool remarkably differ depending on the load acting on the pool floor.

On the other hand, when the means for raising and lowering the pool floor is the latter support means, it is not necessary to limit the support points to only the corner portions, and therefore, the necessary portion, that is, the center portion of the pool floor, is required. Also, it is possible to provide a supporting point, so that it is possible to eliminate in advance the problem that the center portion of the pool floor is easily bent, as in the case of the above-mentioned suspension means.

However, in the case where the means for raising and lowering the pool floor is used as the supporting means by the cylinder driving method or the jack driving method, the screw jack and the fluid pressure cylinder are made to exist below the pool bottom, and the wiring and piping are arranged. There is a problem that a large occupied space is required in the depth direction when constructing the pool.

Further, it is necessary to control the expansion and contraction of at least six screw jacks and fluid pressure cylinders in synchronization with each other, and this control is very difficult.

Therefore, under the present circumstances, although the lifting means of the pool floor is based on the wire driving type or chain driving type suspending means connected to the corner portion of the pool floor, the pool floor itself has a robust structure and is easily bent. It is set to be impossible.

[0012]

However, in such a suspension system, the weight of the pool floor is large because the pool floor is formed to have a robust structure, and as a result, the means for raising and lowering the pool floor becomes large, and the general purpose There was a problem that it could not be expected to improve the sex.

The present invention was devised in view of the above circumstances, and an object thereof is to provide a lifting means for the pool floor as a wire driving type suspension means or the like, even if the center of the floor of the pool or the like is used. It is an object of the present invention to provide a floor device such as a pool that can effectively and surely prevent the bending of a portion and can obtain sufficient rigidity even if the floor structure is simplified.

[0014]

In order to achieve the above object, the present invention is premised on a floor device such as a pool fitted to an opening of a pool and provided with buoyancy. It is characterized in that the weight body is detachably attached to the facing portion of the floor so that the central portion of the floor is curved above the peripheral portion of the floor.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings.

As shown in FIGS. 1 and 2, in a pool 1 according to this embodiment, an opening 1a is formed in a concave shape in cross section, and a pool floor 10 is fitted into the opening 1a by an elevating means 2 so as to be able to move up and down. To be done.

The pool floor 10 has a wire rope 2 which constitutes an elevating means 2 which is connected to the corner portion of the pool floor 10.
Therefore, it is formed so as to move up and down along the wall surface 1b of the pool 1.

Incidentally, although not shown in particular in this embodiment, the elevating means 2 includes a plurality of pulleys for interposing the wire rope 20, a drum for winding or unwinding the wire rope 20, and the drum. It is configured by a wire drive system having a driving machine to be driven and a control device to control driving of the driving machine.

The lifting means 2 is connected to the wire rope 20.
Needless to say, it may be configured by a chain drive system in which the is replaced by a chain.

On the other hand, the pool floor 10 is formed to have a size that completely hides the opening 1a of the pool 1, and in this embodiment, the floor material 11 having a proper size.
It is formed by a floor material group in which a large number of sheets are connected.

The floor material 11 is basically a hollow panel body that is susceptible to buoyancy so that the buoyancy in water is greater than the specific gravity of water. An appropriate material such as rust is used. It is made of strong synthetic resin material, aluminum material or stainless steel material.

Incidentally, in the illustrated example, the floor material 11 is divided into halves on the four sides of the pool floor 10, or the auxiliary floor material 11a in a mode of being divided into four is arranged in a frame shape and is connected to the frame. As described above, a large number of floor materials 11 are connected to form the floor material group.

In this embodiment, the floor member 11 has a connecting portion 1 on the side surface on the lower half side thereof, as shown in FIGS. 3 and 4.
2 has a bolt / nut 13 to the connecting portion 12.
Are connected to each other by mounting, and at this time, the side surfaces on the upper half side are brought into contact with each other.

In FIG. 4, the connecting portion 12 and the bolts / nuts 13 are not particularly shown between the floor members 11 in the vertical direction in the figure, but the floor in the horizontal direction in the figure is shown. Material 1
It is set in the same way as it is set between 1.

Therefore, in the floor material 11, for example,
When the two floor materials 11 are connected, the two floor materials 11
Does not bend in a valley shape around the connecting portion 12, but bends in a mountain shape.

As a result, in a floor material group in which a large number of floor materials 11 are connected, if both ends are fixed,
As shown in FIG. 5, the whole can be curved in a gentle mountain shape.

Unless at least a load action is exerted, the central portion thereof is lower than the horizontal plane shown by the chain double-dashed line in FIG. 5, that is, it cannot be curved in a valley shape opposite to the above-mentioned mountain shape. become.

By the way, instead of the above embodiment, the floor material 11 has flanges 14 formed on at least two sides of its upper end surface as shown in FIG. 6, and when the floor materials 11 are connected to each other. However, consideration may be given to cover the gap formed on the upper end side.

That is, in the above embodiment, the floor material group is curved in a gentle mountain shape, but at that time, a so-called gap is formed at the upper end between the adjacent floor materials 11. Therefore, it is desirable to form the flange 14 that covers the gap at the upper end of each floor material 11 because the gap cannot be left.

When the flange 14 is formed,
As shown in FIG. 6, it is desirable to form a concave portion 15 for accommodating the flange 14 on the side of the floor material 11 that is adjacently provided, and alternatively, the concave portion 15 may be omitted.

The pool floor 10 is constructed such that the weight body 3 is detachably attached to the lower surface in the vicinity of the corner portion thereof, and the weight body 3 is made of a metal plate having an appropriate thickness. Although not shown, it is configured to be held on the lower surface of the floor material 11 by using bolts and nuts, and the number of sheets, that is, the weight can be increased or decreased as necessary.

Since the weight body 3 is arranged in the vicinity of the corner portion of the pool floor 10, the corner portion of the pool floor 10 is forcibly quieted by the weight body 3 in water. Since the buoyancy acts on the central portion, the central portion bends upward as shown in FIG.

As a result, the pool floor 10 can bear the load until the load acts on the upper surface and becomes substantially horizontal. That is, the pool floor is configured so as not to bend downward even when a load is applied, which would cause the center portion to bend downward if originally set horizontally. The load bearing capacity at 10 can be apparently increased.

The floor material 1 disposed at the corners
As shown in FIG. 7, 1 can be configured to have an inner space 16 and a lid 17 can be detachably attached to the upper surface thereof.

When the floor material 11 is formed as described above, the lid body 17 is opened to accommodate the metal plate 30 forming the weight body 3 in the inner space 16, or the metal plate 30 is It is possible to increase or decrease the number of sheets. Compared to the case where the metal plate 30 is connected to the lower surface of the floor material 11 by using bolts, nuts or the like as in the above-described embodiment, the number of the metal plates 30 is increased. There is an advantage that the arrangement and the increase / decrease operation thereof are facilitated.

In the above embodiment, the case where the floor material 11 is formed in a hollow shape has been described as an example, but the present invention is not limited to this, and it may be formed of a plate material, for example. Good.
