Patent number: 8539896Abstract: A swim platform lift mechanism is disclosed, the mechanism mounted between the transom of a boat and a bottom surface of a swim platform. The lift mechanism provides a powered lifting/lowering of the swim platform from a retracted position that is level with the deck of the boat to a deployed position in which the swim platform is below the surface of the water surrounding the boat and from the retracted position to an up-and-over position in which the swim platform and its contents are positioned above and forward of the rear edge of the deck. When in the retracted position, an adjustable stop interfaced to the swim platform abuts rest areas on lower arms of the lift mechanism, thereby providing structural support to the swim platform.Type: GrantFiled: October 26, 2011Date of Patent: September 24, 2013Assignee: Nautical Structures Industries, Inc.Inventors: Robert Bolline, Nicholas Asseff, Sunthorn Ingersoll

Patent number: 8286574Abstract: 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).Type: GrantFiled: February 11, 2008Date of Patent: October 16, 2012Inventor: Peter A.

Patent number: 8061932Abstract: A hydraulic boat lift assembly will raise and lower a boat cradle remotely, and will securely lock the cradle in an uppermost storage position. The lift as provided with a manual mechanism for unlocking the cradle from its uppermost storage position for operation when the hydraulic system is not available. The lift has a support frame that is mountable on the outside of the transom of a boat with hydraulic connections to a hydraulic system and controls within the boat. A lift mechanism connected to the support frame raises and lowers a cradle that supports a small boat or tender. The lift mechanism includes one or more hydraulic lift cylinders. In a retracted position of the lift cylinder, the cradle is elevated above the water in a storage position when the boat is under way. To ensure security of the tender, the lift mechanism employs a lock cylinder that prevents inadvertent motion of the lift cylinder from the retracted position by mechanical and hydraulic mechanisms.Type: GrantFiled: June 19, 2009Date of Patent: November 22, 2011Inventor: Robert P. Latham

Patent number: 7707955Abstract: A lifting apparatus includes a lift arm for carrying a platform or cradle and is pivotally attached to a base for movement between lowered and raised positions. A crank arm is pivotal with the base and a connector arm is pivotal with the lift arm. The crank arm and connector arm are pivotally connected to each other for rotation about a common pivot axis. Rotation of the crank arm by an actuator moves the crank arm and connector arm combination through a top dead center alignment a lowered over center alignment with the lift arm movable from the lowered position to the raised position during operating positions of the apparatus, and to a raised over center alignments with limited movement of the lift arm in the raised position for providing a locking position of the apparatus thus eliminating a need for typical additional locking mechanism.Type: GrantFiled: July 28, 2008Date of Patent: May 4, 2010Assignee: Sealift, Inc.Inventors: Carl E. Johns, Jr., Stephen G. Johns

Patent number: 7293521Abstract: Devices, apparatus and systems for raising and lowering watercraft such as personal watercraft, jet skis, inflatables from transoms on boats, from bulkheads and from docks, and for raising and lowering other types of vessels. A single actuator such as a fluid operated cylinder and single piston can raise and lower a cradle that supports the personal watercraft. An crank bracket can be fixably attached to a crank shaft, and an arm which supports the cradle can be fixably attached to the crank shaft. The arm can be extendable to different lengths. The cradle can include a self-leveling carriage that uses rollers to roll on a curved surface of the cradle allowing the supported watercraft to remain in a substantially level position thereon. An adjustable swivel mount can also be used to lock the cradle to the arm in a fixed orientation.Type: GrantFiled: May 10, 2005Date of Patent: November 13, 2007Assignee: Sealift, Inc.Inventors: Carl E.

Patent number: 6782842Abstract: A boat-lift system adapted to move a smaller boat relative to a larger boat. The boat-lift system comprises a structural support, a lift structure, a pivot system, and an actuator assembly. The structural support is adapted to be rigidly connected to a transom of the larger boat. The lift structure defines a second pivot portion, an actuator portion, an extension portion, and first and second boat-engaging portions. The pivot system connects the first and second pivot portions to allow rotation of the lift structure between first and second lift positions relative to the structural support. Actuation of the actuator assembly causes the lift structure to move between the first and second lift positions. When the smaller boat is in a docking position adjacent to the lift structure, operation of the actuator assembly moves the lift structure to lift the smaller boat from the docking position to a first storage position.Type: GrantFiled: January 6, 2003Date of Patent: August 31, 2004Inventor: Jeff Alvord

Patent number: 6474256Abstract: A dinghy lift for mounting to a boat beneath a swim platform. The dinghy lift includes a pair of space-apart lift mechanisms that are mounted to the stern beneath the swim platform. The lift mechanisms do not extend outwardly beyond the swim platform and therefore are generally hidden from view. A pair of arm are removably mounted to the lift mechanisms. The arms extend outwardly beyond the swim platform to form a cradle for the dinghy. The lift mechanisms selectively move the arms between a lowered position for loading and unloading the dinghy and a raised position for storing the dinghy.Type: GrantFiled: July 20, 2001Date of Patent: November 5, 2002Assignee: Shore-Mate Industries, Inc.Inventor: Wayne A. Vogel

Patent number: 6327992Abstract: A transom bracket enclosing a hydraulic power cylinder is mounted to the transom of a watercraft. An actuation rod of the power cylinder moves multiple lift arms connected to a platform bracket supporting a platform for supporting a small auxiliary watercraft. Electrical or manual operation of the power cylinder causes the platform bracket to move in a vertical direction either upwards out of the water or downwards into the water. A lock mechanism operated by a lock cylinder locks the lift apparatus in place when not in operation. Grooves on sides of the transom bracket and transversely extended pins connecting the linkage arms provide a downward stop to movement of the lift apparatus.Type: GrantFiled: February 1, 2001Date of Patent: December 11, 2001Assignee: General Hydraulic Solutions, Inc.Inventor: Richard A. Martin

Patent number: 6047659Abstract: A mounting apparatus comprises a plurality of main support tubes securely affixed to the transom and substantially hidden within the hull of a marine vessel. The number of main support tubes corresponds with the number of support units of a lifting device. Each of the support units further comprises a plurality of support members where the uppermost support member is secured to a corresponding main support tube. The main support tubes are housed through the transom and below the deck or flooring of the vessel so that when the support members are retracted, they are concealed, or substantially concealed, within the main support tubes.Type: GrantFiled: October 30, 1997Date of Patent: April 11, 2000Inventor: Anthony P. Schmidt, Jr.

Patent number: 4627377Abstract: A platform for a small boat or the like is pivoted to the free end of a pair of arms which are pivoted at their opposite ends to a larger boat such as a yacht. The arms are controlled by an hydraulic jack and a second hydraulic jack is arranged to drive or be driven by the first jack to control the platform so that it is always horizontal for any position of the arms. The arms can position the platform below the water line for launching or receiving the small boat or well above the water line.Type: GrantFiled: February 15, 1985Date of Patent: December 9, 1986Inventor: Alain Zoonens
