Safety equipment for use by e.g. children, in swimming pool, has transmission shafts connecting drive unit to assembly of lifting/descending points to allow displacement of floor between bottom position and surface position

摘要

The equipment has a submersible floor (F) vertically displaced inside a basin of a swimming pool between a bottom position and a surface position. A floor manipulation device is formed by multiple lifting/descending points (U1-U4) that lift/descend the floor. A drive unit (E) rotatably drives the points by transmission shafts (11, 12, 21, 22). The transmission shafts connect the drive unit to an assembly of the lifting/descending points to allow displacement of the floor based on vertical movement inside the basin between the bottom position and the surface position.
