Abstract:
A collapsible, rigid hull, sectional boat assembly, comprising:a) a plurality of separate, individual, rigid, foldable hull section members each forming a transverse segment of the bottom hull and opposite hull side walls of an assembled elongated boat hull, each said hull section member comprising: 1). a substantially rigid sheet formed of a selected synthetic thermoplastic resin material having predetermined, first hinge fold lines defining and foldably dividing the sheet into at least one bottom hull panel and a pair of opposite hull side wall panels foldable relative to each other along mutual said first hinge fold lines between an operative position forming a transverse segment of a boat hull configuration and a collapsed, folded, storage condition in which said hinged panels are disposed in substantially stacked condition, and 2). a pair of opposite rib flaps on each said hull panel formed by opposite, second hinge fold lines positioned on the sheet a spaced distance inwardly of and extending along the opposite, commonly-shared terminal edges of each said hull panel, said second hinge fold lines arranged to permit each said opposite rib flap to be folded into an operative condition extending substantially perpendicularly relative to the plane of the surface of its corresponding hull panel, b) a plurality of substantially rigid rib cap members configured to supportingly engage corresponding rib flaps of adjacent hull panels of adjacent hull sections and releasably secure said plurality of hull sections together in predetermined elongated hull configuration, c) securing means for releasably interengaging and securing said rigid rib cap members and said adjacent corresponding rib flaps together to secure said plurality of hull sections together into a complete, rigid, elongated boat hull, d) a plurality of rigid, foldable top deck section members each comprising a rigid sheet formed of a selected synthetic thermoplastic resin material having first hinge fold lines forming panels configured to allow the deck section to fold in order to overlie at least the top edge of a selected hull side wall panel and be releasably secured to at least one face surface of the selected hull side wall panel, each said top deck section having second hinge fold lines forming at least one pair of opposite deck attachment flaps configured to engage a pair of rib cap members for releasable securement of the top deck section member therebetween, e) securing means for releasably interengaging and securing said rigid rib cap members and corresponding deck attachment flaps together to releasably secure said plurality of top deck section members between said plurality of rib cap members, and f) means for preventing the passage of water between adjacent hull section members into the interior of the boat when the boat is on a body of water, whereby g) the plurality of said hull and deck section members and rib cap members may be quickly and easily assembled into a complete rigid hull boat for use on a body of water and also quickly and easily disassembled, each hull and deck section individually folded into collapsed, stacked condition for extremely compact storage and convenient transport in a carrying bag or backpack.
