Track System Patents (Class 440/35)
  • Patent number: 8801327
    Abstract: An apparatus is provided for moving a floating or submerged marine structure. Embodiments include a track fixedly mounted near or under the waterline surface, extending from a first point to a second point for defining a path of motion of the marine structure. A riser cable has a first end movably attached to the track between the first and second points, and a second end fixedly attached to the marine structure. A trolley is attached to the first end of the riser cable between the first end and the track, and has a roller for engaging the track for distributing environmental forces of the marine structure to the track. A drive unit is attached to the marine structure (or to the trolley) for moving the marine structure (or the trolley) such that the marine structure or one end of the marine structure moves along the path of the track.

  • Patent number: 7232350
    Abstract: The watercraft described herein is a surfboard, skim board, dive board, or boat having a propelling fin driven by a standing surfer or boater with an upward and downward stroke which may be used to propel the watercraft by an upward and downward fin motion. The surfboard and dive board in particular are used on water and may be used to ride ocean swells and waves. The surfer or diver stands on the board and moves a vertical handle upwardly and down-ward. The lower end of this handle is pivotally attached to a parallel bar device having attachment means to the board at a forward end of the parallel bar device and having attachment means to a fin at the aft ward end of the parallel bar device. The fin is generally horizontal and is driven thru the water up and downwardly by the standing user and propels the board forward at higher rates of speed than can be achieved by prone-paddling.
