With the recent fitness boom, it has become the most suitable full-body exercise for improving health and relieving stress.

Swimming has become popular and is enjoyed by everyone from infants to the elderly.

In general, it is important that a pool has a depth that is appropriate for the height and skill level, and it is particularly important to distinguish between pools intended for children and infants and pools intended for adults. Therefore, 1. Usually, pools for adults and pools for children are installed separately.

However, although public facilities may be able to install separate pools for adults and children, private swimming sports clubs and the like cannot afford to do so financially. Therefore, in general children's swimming classes and the like, it is customary to use a part of the adult pool with the water depth adjusted. For example, the most primitive way to adjust the water depth is to manually sink a block-shaped depth adjustment plate to the bottom of the pool. Recently, a method has been known in which a depth adjustment plate is raised from the bottom of the pool to an appropriate height.

The aIg that Akira is trying to solve However, the method of sinking and fixing the upper air blocks to the bottom of the pool cannot be used in practice because it takes too much time and effort to install and remove the blocks. Barefoot,
This is because, in sports clubs and the like, it is necessary to switch from swimming lessons for children to swimming lessons for adults such as housewives in a short period of time, so the work of adjusting the water depth of the pool must be simple and quick. Therefore, the latter method mentioned above, which allows you to adjust the water depth of the pool in a short time, originally has a depth adjustment plate installed at the bottom of the pool so that it can be moved up and down, so the mechanical part becomes an obstacle when cleaning the pool. Cleaning is not done properly, and dirt, hair, sputum, spittle, etc. remain behind, making it unhygienic. There is this inconvenience.

In view of the above-mentioned circumstances, the present invention has been developed with the aim of providing a sanitary method that allows the water depth of a pool to be adjusted easily and quickly.

In order to solve the above-mentioned problems, the present invention supports a platform of a predetermined area that can fit into the pool above the required height of the pool, suspends the platform so that it can be raised and lowered, and as needed. The water depth of the pool is characterized in that the platform is lowered into the pool, placed and fixed on the bottom of the pool to be used as a shallow pool, and then the platform is raised and stored at the top of the pool at a required height. In addition to configuring the adjustment method, a suspension support is fixed to the ceiling of an indoor pool, a stand that can be fitted to the pool is removably suspended from the suspension support via a suspension support rope, and the suspension support is A water depth adjustment device for a pool is constituted by being connected to a winch so as to be able to be wound up and let out, and further, the stand is provided with a locking rod on the side that can move forward and backward toward the beam girder material in the ceiling, and the locking rod is connected to the winch. A ram is pivotally supported on a stand and rotatably connected to a swinging rod, a ram is rotatably connected to the swinging rod, the ram is engaged with an air cylinder, and a locking rod is attached to the beam girder. The platform has a locking recess that engages and disengages, and the platform is slidably provided with a protrusion on the side facing the beam girder material that is movable outwardly by approximately the width of the beam girder material. , a gate-shaped bracket that holds a reinforcing material that can be exposed on the top surface of the stand at the end of the suspension rope; a lock bar that is supported through one side of the bracket so as to be movable toward the other side; A water depth adjustment device for a pool is constructed by connecting a coupler with a slide plate supported vertically movably on the other side of the bracket and having a long hole for engaging with the lock bar.

Diving 1 According to the above configuration, if you want to change the depth of the pool from one for adults to one for children, you can lower the platform to the bottom of the pool and submerge it.
In addition, if you want to change from a children's pool to an adult pool, connect the coupler to the reinforcing material of the stand sunk in the bottom of the pool, wind up the suspension rope with a winch, and lift the stand to the ceiling above the pool. When the cylinder is driven to make the locking rod protrude from the side of the stand and the locking rod is engaged with the lock recess provided in the beam girder material of the ceiling, the stand is safely attached to the beam girder material to prevent it from accidentally falling from the ceiling.
