Abstract: The invention relates to an autonomous reclining seat element in a simple tub, the reclining seat element being locked and rotatably mounted on the edge of the pool and water is efficiently applied to the nozzles by means of a circulating pump with short pipes mounted in the equipment container and the reclining seat element is height-adjustable, tiltable and foldable, as an individual element or, by means of hinges, as multiple elements, and such a reclining seat element has one or more buoyancy bodies, armrests with pushbutton panel and, if required, an unbalance motor.

Abstract: The invention relates to a pool lift attached to the pool edge of a swimming pool and having a platform that is height-adjustable by means of a mechanical cylinder on a pivot lever and having rollers that engage the guide bar, secured against undesired lowering by means of gas springs or with closed buoyancy body and the platform may also accommodate underwater fitness equipment, countercurrent system, folding seat and has a training algorithm by means of a controller.

Abstract: The invention comprises a segmented plate (1) for watercraft which is able to be swivelled into a stair lift, swimplatform or gangway by means of an active cylinder (4), or passive cylinder (44). The plate (2) consists of segmented strips (5), which have flexible elements (19) or are releasable and equipped with sensors (13), so that in case of bending or releasing of a segmented strip (5), on the grounds of a foreign element (15) trapped into the segmented strip (5), the cylinder (4) is stopped by means of the controller (14). Contact bands (16) and light strips (17) and cover (11) additionally increase the safety of the swivelable plate (2).

Abstract: The invention relates to a lowerable platform (1) for a water craft (10), which can be also horizontally extended and to which a float (2) is fastened that comprises a closed hollow space (43) or an open hollow space (43), a buoyancy (A) acting upon the float (2) being generated by the air volume (L). As a result, the water craft's proper weight or the payload (N) of e.g. a tender boar (27) on the lowerable platform (1) can be compensated by the buoyancy (A). A hydrodynamic design of the float (2) additionally generates a hydrodynamic buoyancy (D1) which can be varied in terms of its height in relation to the current (S) by means (4, 37, 38, 39), depending on the float (2).

Abstract: The invention relates to two parallel added floaters (2) for watercraft, which are fixed to the stern (1a) on a watercraft hull (1) or a platform element (31) whereby the single auxiliary bottom (5) is positioned higher or for the most part positioned higher than the hull bottom (6) and forms a step. The added floaters (2) create on the one hand a static lift (As) and on the other hand a dynamic (Ad) lift.
