- The present invention relates to a stern platform assembly for an outboard propelled boat. A boat's outboard engine conventionally means a self-contained unit including the actual engine, transmission and propeller, and configured to be mounted outside the boat transom. The outboard motor is installed on the boat so that it can be rotated around a vertical axis, to provide the ability to tack the boat, and also generally has the ability to be flipped around a horizontal axis to allow the lifting of its lower part in which the propeller is arranged.
- There are known stern platform assemblies for boats with inboard propulsion, provided with a mobile platform due to an articulated parallelogram mechanism. These platform assemblies are not suitable for installation on outboard propulsion boats due to the presence of the engines.

- For this purpose, the object of the invention is a stern platform assembly for an outboard propelled boat, characterized by comprising a pair of stationary side support wings, a movable platform arranged adjacent to the side support wings, and a motion mechanism housed within each of the side support wings and carrying the movable platform, wherein the movable platform is movable between a terminal elevation position, in which it is arranged adjacent to the top of the side support wings, and a terminal lowering position, while keeping a predetermined orientation with respect to the side support wings and keeping a closeness relationship with them, and wherein, when viewed in plan view, the assembly encompasses a room circumscribed on three sides by the movable platform and by the side support wings.
- With a configuration of this type, it is possible to dimension the platform and the lateral support wings so that the space they circumscribe is sufficient to accommodate the outboard engines and to avoid interference with the latter when the movable platform is lowered or raised.
- At the same time, it is possible to maintain an accessibility to the platform from the boat, at whatever elevation it is. Advantageously, since the platform extends continuously in front of the engines, when it is lowered it also acts as a safety barrier which prevents or at least limits access to the propellers by the swimmers.
