Abstract
A new boat hull support structure is provided in which a chevron rib support structure is used throughout the hull of an aluminum boat. This rib structure provides superior resiliency due to the increase of surface area contact between the boat hull and support ribs. The support ribs are constructed from a plurality of V-shaped ribs, having summit sections and trailing ends connected to transverse braces. The ribs are riveted to the hull, with each successive rib connected to the preceding rib at a point in the forward one quarter of the preceding rib and the center of the transverse brace through a connector plate. A continuous triangular structure is provided which distributes impact loading across the width, as well as, the length of the structure.
Claims20
A chevron rib structure for providing support in a boat hull, said boat having a fore, said structure comprising:
- a hull, having fore and aft sections, including opposite side sections extending along a length of said hull, said side sections combining at a keel line extending along a longitudinal center axis of said hull;
- a plurality of triangulated structures pointing to said fore of the boat and being formed by a plurality of V-shaped ribs and a plurality of cross beams connected thereto;
- each said V-shaped rib being secured to an inner surface of said hull and aligned with respect to other said V-shaped ribs in a chevron configuration,
- each of said ribs including legs which join to form said V-shape,
- each of said ribs having a summit section proximate an apex thereof and a valley section between adjoining legs,
- said ribs being positioned proximate one another such that said summit section of each rib extends into said valley section of a preceding rib located fore thereof,
- said legs having lower surfaces secured to said hull;
- each of said cross beams being secured to at least one corresponding V-shaped rib,
- each of said cross beams traversing said boat hull.
A support structure for providing support in a boat hull comprising:
- a plurality of independent triangulated structures having apexes pointing toward a fore section of said boat hull;
- each of said triangulated structures being formed by a cross beam connected to outer ends of a pair of legs of a rib structure, said pair of legs meeting at an apex of the triangulated structure;
- said triangulated structures being at least partially nested.
A chevron rib structure for providing support in an aluminum boat hull, said boat having a fore, said structure comprising:
- a hull, having a bow and a stem, the hull including opposite side sections formed of aluminum and extending along a length of said hull, said side sections combining at a keel line extending along a longitudinal center axis of said hull;
- a plurality of symmetric V-shaped ribs pointing to said fore of the boat, each said V-shaped rib being secured to an inner surface of said hull and aligned with respect to other said V-shaped ribs in a chevron configuration,
- each of said ribs including first and second legs which join at a first angle to form said V-shape,
- wherein each said first leg directly contacts a corresponding second leg at said keel line of said boat, so that said first legs are not separated from the corresponding second legs,
- said legs having lower surfaces secured to said hull,
- wherein said V-shaped ribs extend substantially the entire distance from said bow to said stern;
- and
- a plurality of cross beams, each of said cross beams being secured to at least one corresponding V-shaped rib,
- each of said cross beams traversing said boat hull.
