  • Patent number: 5622136
    Abstract: The present invention is a boat canopy mounting system for securing a boat canopy to a boat. The system includes a first member such as a header for attachment to the boat. The first member includes at least one channel having a restricted opening. The second member is adapted to be attached to a boat canopy and has at least one locking flange for insertion into the channel of the first member. The boat canopy can be repeatably connected to and disconnected from the boat by positioning the second member against the channel of the first member and pressing against the second member to force the flanges into the channel. The second member is removable from the channels by pulling the second member away from the channels to disengage the flanges from the channels.

  • Patent number: 5189980
    Abstract: A rounded top header extrusion for boat windshields being constructed as a unitary extruded member for rigidly engaging a boat windshield. The extrusion provides a curved upper surface for supporting a boat canopy, and a recessed channel extending inwardly into the extrusion for receiving a fastener or similar article for attachment of a boat canopy. The extrusion is defined in cross-section by a pair of generally parallel arms forming a windshield engaging channel, and a generally semi-circular rail portion extending across the channel between the arms.
