Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multipurpose indoor pool which can be used for various purposes such as adjusting the depth of the pool and the floor structure when not in use.

[0002]

2. Description of the Related Art Recently, as a pool facility, indoor facilities have been increasingly installed with the development of general gymnasiums, swimming schools, fitness clubs, rehabilitation centers and the like. Moreover, in this case, from the general usage that uses the entire pool water depth as the usage state of the pool, adjusting the depth by elevating the bottom (floor) such as a swimming school or rehabilitation center, or the pool in the general gymnasium. As described above, various forms such as a floor covering structure for closing the pool when not in use in winter have been demanded. Therefore, it is desired to add equipment to the pool body according to the purpose of use.

Conventionally known methods for adjusting the bottom position of a pool are to simply bring a plastic shank into the lower part of the course to be manually sunk to make the water depth shallow, or to adjust the bottom of the pool. As a thing, a cylinder is vertically buried in the bottom of the pool body, a floor bottom is attached to the upper end of the rod part of the cylinder, and this floor bottom is moved up and down by the operation of the cylinder to obtain a water depth suitable for children's use. (See Japanese Patent Laid-Open No. 4-209272).

For example, as shown in FIG. 6, an elevating floor bottom body b laid horizontally at the bottom of the pool body a is replaced by a pool body a.
A plurality of vertical cylinders c which are vertically buried directly at the position of the bottom portion a'of the rod c'become attached to the ends of the rods c ', and the cylinder c is operated by an appropriate pressure generator d to operate the rod c'.
The bottom floor b of the lifting floor is located inside the pool main body a and is lifted up and down according to the amount of feeding, and the pool depth is automatically adjusted.

[0005]

However, it is a very troublesome work to put in and out a large number of bottom raising bridges having a simple trapezoidal construction like the former (a single cage is heavy, an instructor Are forced to work hard). In the latter type, in which the cylinder is vertically buried in the bottom of the pool body, a predetermined space (dimension) cannot be secured between the ceiling and the downstairs in a pool facility such as a building often used recently or on a rooftop. Due to its narrow size, it is not possible to embed vertically used cylinders directly in the pool bottom. In particular, in a pool with a deep water, the size of the cylinder is also increased, so that it is virtually impossible to provide this type of lifting mechanism (device).

In view of the above situation, the present invention solves the above problems by incorporating a lift mechanism for a lift floor bottom body arranged at the bottom of a pool body into a cylinder provided with a stroke doubling mechanism at a side wall of the pool body. It is intended to provide a multipurpose indoor pool to be solved.

[0007]

According to the present invention, a plurality of mechanism-incorporating vertical groove portions are formed on both side wall portions of a pool body, and a predetermined number is provided at a rod end of a vertical cylinder provided in each of the mechanism-incorporating vertical groove portions. A moving pulley having a diameter is attached, one end of a rope hanging on the moving pulley is fixed to the main body side, and the other end of the rope reversed through the moving pulley is made to face the lower position of the cylinder so as to support the lifting arm. The lifting and lowering floor bottom body arranged in the pool body is supported by each of the lifting and lowering support arms that laterally protrude into the pool body, and follows the vertical movement of the movable pulley. The lifting floor bottom body is lifted and lowered between the pool bottom and at least the pool bottom.

Further, the lifting floor bottom body is a cage-like bottom floor body having a floor area almost equal to the bottom area of the pool body.

Further, the lifting floor bottom body is a small baby-bottom floor floor body that occupies a part of the bottom area of the pool body.

Further, the lifting support arm is a lifting support arm having a stroke sensor.

As described above, the lifting floor bottom body separately laid on the bottom of the pool body is provided with the vertical cylinder in the vertical groove formed on the side wall side of the pool body, and the rope is hung on the movable pulley provided at the end of the rod portion. In order to support the rope, even if there is a room etc. downstairs, if the space for building the pool body is provided, the lifting mechanism for the lifting floor bottom can be arranged. Moreover, the lifting mechanism is supported by the lifting support arm because the rope hanging on the moving pulley at the end of the rod of the vertical cylinder has one end facing the body side and the other end facing the lower side of the cylinder. The raising / lowering width of the raised / lowered floor bottom body becomes an increased stroke (doubled raising / lowering) which is adjusted from the lower position of the cylinder to the rod winding amount of the cylinder and the winding position of the rope due to the rise of the moving pulley. To the water surface quickly, and this allows a given floor bottom to be lifted with a minimum of cylinder usage.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to the drawings of the embodiments.

1 to 3 show an embodiment of an indoor pool in which the lifting floor bottom body has a shape having a size substantially equal to the bottom area of the pool body. Reference numeral 1 denotes a pool main body having a predetermined depth, and a plurality of mechanism-incorporating vertical groove portions 2 are formed in the wall surface of both side wall portions 1a on the left and right sides in the longitudinal direction of the pool main body 1 at regular intervals to form each of these mechanisms. Vertical cylinders 3 driven by hydraulic pressure, air pressure, etc. are erected in the built-in vertical groove portion 2 (for example, three groups are arranged on the left and right sides in a 25M pool), and can be extended above the respective vertical cylinders 3. The movable pulley 6 is attached to the upper end of the rod portion 4 by holding the supporting tool 5 appropriately. One end (base end) of the rope 7 to be hung on the moving pulley 6 is locked to a stopper 8 fixed to the foundation side of the mechanism-incorporating vertical groove portion 2, and the other end (tip end) which is inverted downward through the moving pulley 6 ) Is made to face the lower side position of the vertical cylinder 3 with at least the rod portion 4 contracted, and the lower end of the rope 7 is provided with an elevating and lowering supporting arm 9 that laterally projects into the pool body. The entire structure of the die cylinder 3, the moving pulley 6, and the rope 7 constitutes a stroke doubling lifting mechanism 10. 11 is each of the above-mentioned ropes 7
It is a lifting floor bottom body in which the lifting support arms 9 at the ends are locked in a predetermined position around the lifting arm. The structure of the lifting floor bottom body 11 has a floor area whose size is substantially equal to the bottom area of the bottom portion 1b of the pool body 1, and the lifting floor bottom body 11 itself and the main beam 12a passing to the left and right. A large number of shroud plates 13 are arranged on the base part 12 in which the sub beams 12b orthogonal to each other are assembled in a lattice with a constant interval f (for example, about 8 mm), and the lower side edges between the shank plates 13 are, for example, cross section. The floor surface is formed by partially connecting the connecting tools 13a having a character shape. Reference numeral 14 is a stroke sensor arranged at the base of each lifting support arm 9 of a well-known control device 15 which separately arranges the amount of extension of the rod portion 4 of each cylinder 3 in accordance with a position regulation signal of the stroke sensor 14. It is controlled by operation so that the lifting floor bottom body 11 is constantly kept in a horizontal state, and the multipurpose indoor pool 16 is constructed in the above-mentioned overall configuration. In this case, if the structure of the rope 7 is, for example, the chain 7a is used, the moving pulley 6 uses the sprocket 6a, and if the wire 7b is used, the moving pulley 6 uses the grooved pulley 6b. Reference numeral 17 denotes an anchor that is embedded on the foundation side for fixing the vertical cylinder 3.

To explain this action, first, in the case of using an ordinary pool having a predetermined depth, the lifting floor bottom body 11 is lowered to the lowest position (bottom position) of the pool body 1. That is, the rod portion 4 of the plurality of vertical cylinders 3 incorporated on the side wall portion 1a side of the pool body 1 is contracted by appropriately operating a known pressure generating device 18 for hydraulic pressure or pneumatic pressure and switching the valve. The movable pulley 6 provided at the upper end of the rod portion 4
A set in which the lifting / lowering floor bottom body 11 supported by the lifting / lowering support arm 9 is sunk to the lowermost bottom portion of the pool so that the lifting / lowering support arm 9 at the end of the rope 7 that is hung on And

Here, when the pool bottom is to be raised and the water depth should be made shallower when swimming or rehabilitation of children, if the vertical cylinder 3 is operated and the rod portion 4 is extended by an appropriate length, A moving pulley 6 integral with the end of the rod portion 4
Since the rope 7 also rises, the rope 7 hung on the movable pulley 6 is
Since one end (base end) is fixed, the other end of the movable pulley 6 which is inverted while being rotated is rolled up, and the lifting support arm 9 at the end of the rope 7 moves upward to raise the lifting floor bottom body 11 to an appropriate height. Ascend to form a shallow bottom body (see the position indicated by the alternate long and short dash line in FIG. 1). At this time, the ascending / descending stroke of the ascending / descending support arm 9 is an increasing stroke in which the amount of extension (extension amount) of the rod portion 4 and the amount of pulling up of the rope 7 accompanying the ascending of the moving pulley 6 are taken into account, and the speed is doubled (double the stroke). The elevating floor bottom body 11 can move to the elevating mechanism.

This doubling of the stroke means, for example, as shown in FIG. 4, if the rod portion 4 of the vertical cylinder 3 is extended by an amount of m, the cord 7 facing the lower portion of the cylinder 3 at the contracted position of the rod portion 4. The lifting / lowering support arm 9 at the end doubles as the amount of extension (extension) m of the rod portion 4 and the moving pulley 6 moves up. That is, the feeding length (stroke) of the cylinder 3 is set to 1
Then, the moving distance (n to n ') of the elevating support arm 9 at the end of the rope 7 that is wound up by the rise of the movable pulley 6 becomes 2. This results in the maximum lifting amount with the smallest cylinder.

Further, when the lifting / lowering floor bottom body 11 is moved up and down, the lifting / lowering floor bottom body 11 itself basically has a cage-like bottom structure, so that the water resistance is minimized and the load on the cylinder is reduced. ing.

Further, in the floor mode in which the pool is not used in the winter season and covers the pool mouth, if the vertical cylinder 3 is operated and the rod portion 4 is extended to the maximum extent after performing a predetermined draining work, The movable pulley 6 at the end of the rod portion 4 also rises to the highest position, the lifting support arm 9 at the end of the rope 7 is pulled up to the highest position, and the lifting floor bottom body 11 supported by the lifting support arm 9 also reaches the highest position. It rises and closes the pool mouth (see Fig. 3). At this time, if there is a slight gap between the upper surface of the lifting floor bottom body 11 and the pool edge (drinking surface), an appropriate auxiliary piece 1
It is possible to arrange a large number of 9 and make the floor surface flush with the poolside 1c.

FIG. 5 is another embodiment showing a partial arrangement in which the lifting floor bottom body is only on one side of the pool. In this case, for example, in a vertically long pool, it is equipped on the front side in the longitudinal direction. That is, one or two mechanism-incorporating vertical groove portions 2 are formed on both side wall portions 1a of the pool body 1 in the same manner as described above, and each mechanism-incorporating vertical groove portion 2 is provided with a vertical cylinder 3 and the rod portion Four
The movable pulley 6 is attached to the upper end of the rope, and the rope 7 hung on the movable pulley 6
One end is fixed to the base end side and the other end (lower end) which is inverted is provided with a lifting support arm 9 so as to project, and the lifting support arm 9 supports a small lifting floor bottom body 11.

Here, when it is desired to partially shallow the pool bottom for swimming or rehabilitation of children, the vertical cylinder 3 is actuated in the same manner as described above, the rod portion 4 is properly extended, and the movable pulley 6 is raised. Then, the small lifting floor bottom 11 supported by the lifting support arm 9 provided at the end of the rope 7 hung on the movable pulley 6 rises and stops at a predetermined position. That is, the bottom body (elevating floor bottom body 11) on one side of the pool main body 1 rises by an appropriate height to form a shallow bottom body. Of course, also in this case, the lifting / lowering movement of the lifting floor bottom body 11 can be performed by doubling the stroke as described above.

[0021]

As described above, the multi-purpose indoor pool of the present invention has a structure in which a plurality of vertical cylinders are incorporated in both side wall portions of the pool body, and the ropes attached to the movable pulley attached to the rod end of each cylinder. Since the lifting floor bottom is supported by the lifting support arm at the tip of the, the lifting support arm moves the cylinder rod out and the moving pulley moves up when the lifting floor bottom is raised by so-called bottom raising of the pool. Due to the double movement of the stroke doubling lifting mechanism, which is performed in combination with the hoisting of the rope, the lifting and lowering of the floor bottom body can be easily and reliably obtained. Moreover,
Since this vertical cylinder is installed on both side wall portions of the pool body, it can be installed without being affected by the downstairs, etc., as long as the pool with a predetermined depth can be constructed.
It is ideal for pool facilities such as indoor pools. In addition, since a double stroke lifting mechanism is used, a single cylinder can be used to obtain a predetermined lifting amount, so a compact device can be obtained from this point as well. The floor bottom can be quickly moved up and down from the bottom of the pool to the water surface. Moreover, even when the floor is used as a lid when the pool is not used, such as in the winter season, the floor bottom body can be easily lifted to the maximum position.
