Abstract: A multifunctional training apparatus for training the lower limb muscles includes a training bench adapted to support a user in a desired training position, a movable rotatable support unit for resisting a muscular force of a lower limb which is caused by a reciprocating movement, a contrast member that is adapted to provide a resistance force against the movement of the movable support unit, and a support element that is adapted to pivotally support the movable support unit and the contrast member. The support element is mounted on the training bench by a rotatable coupling about an axis that is at an angle with respect to the training bench, such that the movable support unit can rotate from a first substantially vertical position to a second substantially horizontal position. In this way, training movements of the lower limbs are possible according to movement in a vertical plane and in a horizontal plane, using a single training device.

Abstract: A floating self-propelled cleaning device (10) for water surfaces, in particular swimming pools, comprises a central floating body (11) and two side floating elements (12) to it connected at opposite sides by two arms (14) to which two net-shaped collecting containers (13) are fastened. The net-shaped containers (13) have openings (17) that allow the inlet of impurities, but prevent the outlet thereof during possible stops or under the action of waves that can occur during the travel on the water surface. The floating device (10) is driven by propelling means (20) and (30) that substantially cause the side floating elements (12) to rotate about an instantaneous centre of rotation located approximately at the central body (11). The rotation of the side floating elements (12) is associated to a shifting movement caused by at least a distribution element (15) movable with respect to the floating body (10).
