2. Description of the Related Art In recent years, swimming has become popular as a sport that can be performed from infants to elderly people, with the rise of health management awareness, and many facilities such as swimming gloves have been developed.

[0003] However, conventionally, most of the pools provided in these facilities are formed at a depth that allows adults to swim. When these pools are used for middle or infants, Since it is necessary to variably adjust the depth of the pool to make it shallow, various types of devices have recently been proposed that can adjust the depth of the pool to an arbitrary depth.

[0004] For example, a method in which a number of tables having legs are arranged on a fixed floor surface of a pool and the table is removed when used by an adult, and a lifting floor is a bellows method, a pantograph method or a cylinder method, a wire chain method, etc. Various types are known.

However, in the above-mentioned conventional pool raising and lowering apparatus, even if the raising and lowering floor is set at a desired height position, it can be slightly moved up and down or rolled by waves or movement of a user. In addition, when a large number of underwater exercises are performed, it is easy to give the user a feeling of instability, and there is also a problem of lack of safety.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has as its object the purpose of setting the floor of a pool or the like to a desired height position and then setting the floor of the pool or the like to roll. It is an object of the present invention to provide a device for preventing the unstable movement of the elevator from being rolled up and having excellent safety.

[0007]

In order to achieve the above object, according to the present invention, air is sealed so as to be movable vertically along an opening of a pool or the like so that buoyancy in water is substantially zero. A first arm attached to the fixed floor side and a second arm attached to the lower part of the elevator floor, which are provided with a device for preventing the elevator from rolling while holding the raised floor at a desired height position. The first arm and the second arm are configured such that the distal ends of the first arm and the second arm are pivotally supported via a shaft so as to be able to flex and extend.

In this case, the first and second arms are:
By forming the channel from a wide channel material, it is possible to more reliably prevent the floor from rising and falling.
