Abstract
A kayak characterized by a kayak hull molded of semi-rigid material stiffened by an internal frame structure which includes a bow and a stern beam units and a seat each of hollow and watertight construction to provide buoyancy and each of limited dimensions to be inserted through the opening in the top of the kayak. The beam units are engaged between the top and bottom walls of the hull, extend longitudinally and centrally of the latter forwardly and rearwardly of the passenger opening and have beam extensions projecting towards each other along the portion of the hull bottom wall opposite the passenger opening. The seat rests on both extensions, is preferably adjustable fore and aft along the latter and also engages the top of the kayak on both sides of the passenger opening to coact with the bow and stern parts in stiffening the semi-rigid hull.
Claims17
A kayak comprising a semi-rigid elongated hull integrally molded in a single unit and defining a top wall, side walls and a bottom wall, said top wall having a passenger opening intermediate the ends of said hull, said top wall having bow and stern top wall portions extending between said opening and both ends of the hull respectively, said top wall further having lateral top wall portions extending between the sides of said opening and said side walls, said bottom wall having an intermediate bottom wall portion opposite said opening and bow and stern bottom wall portions extending between said intermediate bottom wall portion and both ends of the hull respectively and opposite said bow and stern top wall portions respectively, and an internal frame structure for stiffening said hull, said structure made of three separate component parts, each of a size allowing its insertion into said hull through said passenger opening, said component parts including a bow part, a stern part and a seat part, said bow part and stern part being each an elongated panel-like member positioned within said hull in an upright plane centrally and longitudinally of said hull, extending between said top wall and bottom wall and spaced from said side walls and each having continuous top and bottom edge surfaces conforming to and contacting the inside faces of said bow top and bottom wall portions and of said stern top and bottom wall portions respectively, said bow and stern parts each having a beam extension projecting from the end of the respective bow and stern parts adjacent said opening, said beam extensions projecting one towards the other longitudinally of said hull, having a top edge surface at a lower level than the top edge surface of said bow part and stern part, and having a bottom edge surface forming a continuation of the bottom edge surface of said bow part and stern part respectively and conforming to and contacting the inside face of said bottom wall, said seat part located opposite said opening having a central seating portion overlying and resting on both said beam extensions, extending transversely of said hull, conforming to and contacting said intermediate bottom wall portion on each side of said beam extensions and provided with upstanding lateral wings conforming to and contacting the inside face of the respective lateral top wall portions of said hull, whereby said seat part coacts with said bow part and said stern part to resist upward thrust which may be exerted on said bottom wall.
A kayak comprising an integrally molded one piece elongated hull of semi-rigid material and defining a bottom wall, side walls and a top wall which latter has a passenger opening of restricted dimensions relative to said top wall so that the latter extends fore and aft and also laterally from said passenger opening, and an internal frame structure to stiffen said hull, said structure including three separate parts each having dimensions permitting its insertion within said hull through said passenger opening, two of said parts being each an elongated panel-like member positioned in an upright central longitudinal plane within said hull fore and aft of said passenger opening respectively, extending between, contacting and conforming to said top and bottom walls, each of said panel-like members having a beam extension projecting from the end of said member proximate to said passenger opening towards the beam extension of the other panel-like member, both beam extensions extending longitudinally along said bottom wall, contacting and conforming to the same, the third separate part being a seat located within said hull below said passenger opening, having a U-shaped cross-section defining a lower central seating portion resting on said two beam extensions and a pair of upwardly directed side wings extending close to the respective side walls and having upper ends engaged underneath and contacting said top wall laterally of said passenger opening.
