Abstract
The invention comprises a segmented platform (1) for watercraft which, which serves as a stair lift, swimplatform or gangway and can be lowered by an active or passive cylinder (4) and a parallelogram (3). The platform (1) consists of plates (2) and optional lateral lifting bodies (8), as well as of a locker (11,12) whereby the whole unit can be tilted up by the bearing (6) attached to the side plates (7) and in addition a down stroke (H1,H2,H3) is created by a second parallelogram (28) or pivot mean (29), therefor the watercraft takes up less space when not in use. The plates (2) can have a cover (21) in the form of a strap (18) and when lifting the plates (2) a higher safety for people is made possible.
