Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pool floor elevating device that firmly and reliably holds a pool floor configured to be able to ascend and descend along a wall surface of a pool at a desired height position.

[0002]

[Prior art and its problems]

 In recent years, with increasing awareness of health care, swimming has become popular as a sport that can be played by infants to the elderly, and as a result, pools that are deep enough for adults to swim can be used for middle-aged or infants. In order to be usable, a proposal has been made that a pool floor, which is a movable floor, can be supported at an arbitrary depth position, and various lifting devices for the pool floor for that purpose have been proposed.

As an example of such an elevating device, although not shown, the bottom floor of the pool is formed thick and a plurality of air supply / exhaust passages are provided in the bottom floor while the air supply A large number of bellows-type columns are connected to the exhaust passages, and the bellows-type columns support a pool floor, which is a movable floor configured like a cage, and are compressed from the air supply source through the air supply and exhaust passages. The pool floor is configured to be supported at an arbitrary height position by supplying and discharging air to and from the bellows type columns.

However, in the above-described conventional lifting device, since the bottom floor of the pool is formed thick and a plurality of air supply / discharge passages are provided on the bottom floor, the pool formation itself is large. In addition to this, there is a disadvantage that the cost increases due to a demand for a larger air supply source including a compressor and the like.

On the other hand, instead of the above-mentioned bellows type support, a screw jack type drive cylinder is erected on the bottom floor of the pool, and when the pool floor is supported by this drive cylinder, it is necessary for them to use the bottom floor of the pool. Since it is not necessary to make the wall thick, there is an advantage that the formation of the pool itself does not take a large amount, but there is a disadvantage that the lifting range of the pool floor is limited by the basic length of the drive cylinder.

In order to avoid the above disadvantage, if the drive cylinder is buried in the bottom floor of the pool or below the bottom floor, the pool itself becomes large and the cost becomes high. Had.

The present invention was devised in view of the present situation, and an object thereof is to smoothly and surely ascend and descend a pool floor which is a movable floor fitted in an opening of a pool. In addition, by arranging the drive source for the pool floor on the side wall of the pool, there is no need to open a hole in the bottom floor of the pool, which facilitates construction and greatly reduces the cost of the pool floor. It is intended to provide a lifting device.

[0008]

That is, one link member 33 forming the link 31 is connected to the pool floor 10 and the bottom floor 1c of the pool 1 via the bracket 34, and the other link member 33 forming the link 31 is connected. The link member 35 is movably arranged on the pool floor 10 and the bottom floor 1c of the pool 1 via a roller 36.

The roller 36 is configured to roll in a guide rail 37 provided on the pool floor 10 and the bottom floor 1c of the pool 1.

On the other hand, the drive shaft 32 has its tip end portion connected to the plurality of links 31 and its base end side connected to the drive source M, and the forward and reverse rotation operation of the drive source M causes the drive shaft 32 to move in the axial direction. It is configured to be moved back and forth.

That is, the drive shaft 32 has a threaded portion 32a formed on the base end side thereof, and a drive gear 38 meshes with the threaded portion 32a. It is configured to be rotated in the forward and reverse directions by M.

The base end of the drive shaft 32 is rotatably supported by the bearing 39, and the intermediate portion thereof is provided with a seal member 1e fitted in a hole formed in the wall 1d of the pool 1. It is supported in a liquid-tight manner.

The drive source M is preferably arranged in, for example, an observation room R formed over the wall 1d of the pool 1, but instead of this, it is arranged in, for example, a pump room or a machine room. Good.

As described above, by installing the drive source M in the observation room R or the like connected to the pool 1, it is not necessary to set a large occupancy range in the so-called vertical direction of the pool 1, and the pool 1 itself It is easy to form. Further, in recent years, the observation room R over the wall is often provided in the pool 1, so that the observation room R is used as the installation site of the drive source M to separately form a chamber for the drive source M 1. You don't have to.

Therefore, in the pool floor raising / lowering device configured as described above, the pool floor 10 fitted to the opening 1a of the pool 1 so as to be able to move up and down is the pool floor 10 and the pool 1 The pantograph type link device 30 arranged between the bottom floor 1c and the bottom floor 1c is driven to move up and down to a desired height position.

When the drive shaft 32 constituting the pantograph type link device 30 is rotationally driven by the drive source M, the drive shaft 32 is axially moved forward and backward, and the forward and backward movement of the drive shaft 32 causes the link 31 to move. Is undulated on the lower surface side, so that the pool floor 10 moves up and down along the wall surface 1b of the pool 1.
