Abstract
Longitudinal bow and stern beams are disposed vertically within a kayak hull. A stiffening tube extends beneath the beams. A tube and the beam holder overlaps a lower portion of each beam and rests on the center portion of the stiffening tube for holding the stiffening tube in place and tying the bow and the stern beams together. The holder is maintained in place by a seat which is pressure fit within the cockpit of the kayak. The upper ends of the bow and stern beams are restrained from lateral movement by upper beam holders mounted to the kayak hull. The system allows greater flexure of the kayak hull with less likelihood of the bow and stern beams becoming dislodged.
Claims19
A kayak comprising:
- (a) an elongated hull, said hull having a bow portion and a stern portion, and having an upper wall and a lower wall;
- (b) a framework disposed within said hull, said framework including:
- a first frame member disposed in said bow portion and extending substantially between said upper wall and said lower wall;
- a second frame member disposed in said stern portion and extending substantially between said upper wall and said lower wall;
- (c) means for longitudinally aligning said first and said second frame members, said aligning means being positioned generally longitudinally of said hull between said first and second frame members;
- and
- (d) seat means disposed on top of said aligning means for holding said aligning means against said lower wall of said hull, wherein said seat means has a longitudinal tunnel formed in the bottom thereof, said aligning means being received in said tunnel in contact with said seat means, said aligning means including portions extending fore and aft of said seat means, said portions having covered recesses contacting, respectively, said first and second frame members for aligning said frame members.
A kayak comprising:
- an elongated hull, said hull having a bow portion and a stern portion, and having an upper wall and a lower wall;
- a framework disposed within said hull, said framework including:
- a first frame member disposed in said bow portion and extending substantially between said upper wall and said lower wall;
- a second frame member disposed in said stern portion and extending substantially between said upper wall and said lower wall;
- a seat;
- and separate thigh brace means positioned on opposite sides of said first frame member for providing a surface for forcing the legs of an occupant of the kayak against, said thigh brace means including first mounting means comprising a pair of laterally spaced surfaces for contacting opposite sides of said first frame member and inhibiting lateral displacement of said first frame member, said first mounting means being positioned between said thigh brace means.
A kayak comprising:
- an elongated hull, said hull having a bow portion and a stern portion, and having an upper wall and a lower wall;
- a framework disposed within said hull, said framework including:
- a first frame member disposed in said bow portion and extending substantially between said upper wall and said lower wall;
- a second frame member disposed in said stern portion and extending substantially between said upper wall and said lower wall;
- first mounting means attached to said upper wall to restrain lateral movement of said first frame member;
- and
- second mounting means attached to said upper wall for restraining lateral movement of said second frame member;
- wherein at least one of said first and second mounting means comprises a pair of laterally spaced projections contacting opposite sides of said restrained frame member, and means for adjusting the distance between said projections, said adjusting means comprising a flexible web connecting said projections, and means for moving said web to different spaced positions relative to said kayak hull upper wall for varying the angle of said projections relative to each other.
