Abstract
Abstract A rigid hull boat made up of detachable bow and stern sections. These are joined at abutting transverse bulkheads: male locking lugs project from the bulkhead of the bow section, and these are received in corresponding recesses in the bulkhead of the stern section. The upper edges of the bulkheads are held together by a channel member through which bolts are passed. The interlocking elements eliminate side-to-side movement between the two bulkheads, and also prevent them from spreading apart at the bottom. There are also bevels around the edges of the two sections which guide the locking members into engagement. The bow section nests within the stern section for storage. If desired, the two sections can be used as independent craft, and in some embodiments, the bow section may be inverted and mounted atop the stern section to provide an enclosed cartop carrier.

Claim 1
Independent Claim
404 words
A segmented boat, comprising: at least first and second sections, each said section having a transversely extending bulkhead at an end thereof; and engagement means for selectively locking said transversely extending bulkheads together in face-to-face abutment along a substantially common plane so as to assemble said boat, said engagement means comprising: (a) a plurality of vertically elongate lugs formed on a first said bulkhead and extending substantially the full height thereof, each said lug having: (i) an outer face which slopes downwardly and outwardly at an inclined angle relative to said common plane, and (ii) first and second vertically extending edge faces which border said outer face and extend at a generally perpendicular angle to said common plane, a lower edge of each said lug being undercut so that a downwardly and outwardly extending flange portion is formed thereon, and said plurality of lugs being separated laterally by at least one flat area on said bulkhead which extends generally in the direction of said common plane; and (b) a plurality of vertically elongate recesses formed in a second said bulkhead and extending substantially the full height thereof for receiving said lugs on said first bulkhead, each said recess having: (i) an inner face which slopes downwardly and inwardly at said inclined angle relative to said common plane, and (ii) first and second vertically extending edge faces which border said inner face and extend at a generally perpendicular angle to said common plane, a lower end of said recess having an upwardly extending lip so that a downwardly and inwardly extending socket portion is formed therein for receiving a said flange portion of a said lug, and said plurality of recesses being separated laterally by at least one flat area on said bulkhead which extends generally in said direction of said common plane; whereby said first and second sections of said boat may be joined by moving said first bulkhead toward said second bulkhead and downwardly until said flat areas on said first and second bulkheads come into abutment generally along said common plane, so that said flange portions on said lugs enter into said socket portions in said recesses in locking engagement therewith so as to prevent separation of said bulkheads in a longitudinal direction, and said vertically extending edge faces of said lugs and said recesses are positioned in abutting engagement so as to prevent motion between said bulkheads in a side-to-side direction.
Claim 2
Dependent Claim
404 words
A segmented boat, comprising: at least first and second sections, each said section having a transversely extending bulkhead at an end thereof; and engagement means for selectively locking said transversely extending bulkheads together in face-to-face abutment along a substantially common plane so as to assemble said boat, said engagement means comprising: (a) a plurality of vertically elongate lugs formed on a first said bulkhead and extending substantially the full height thereof, each said lug having: (i) an outer face which slopes downwardly and outwardly at an inclined angle relative to said common plane, and (ii) first and second vertically extending edge faces which border said outer face and extend at a generally perpendicular angle to said common plane, a lower edge of each said lug being undercut so that a downwardly and outwardly extending flange portion is formed thereon, and said plurality of lugs being separated laterally by at least one flat area on said bulkhead which extends generally in the direction of said common plane; and (b) a plurality of vertically elongate recesses formed in a second said bulkhead and extending substantially the full height thereof for receiving said lugs on said first bulkhead, each said recess having: (i) an inner face which slopes downwardly and inwardly at said inclined angle relative to said common plane, and (ii) first and second vertically extending edge faces which border said inner face and extend at a generally perpendicular angle to said common plane, a lower end of said recess having an upwardly extending lip so that a downwardly and inwardly extending socket portion is formed therein for receiving a said flange portion of a said lug, and said plurality of recesses being separated laterally by at least one flat area on said bulkhead which extends generally in said direction of said common plane; whereby said first and second sections of said boat may be joined by moving said first bulkhead toward said second bulkhead and downwardly until said flat areas on said first and second bulkheads come into abutment generally along said common plane, so that said flange portions on said lugs enter into said socket portions in said recesses in locking engagement therewith so as to prevent separation of said bulkheads in a longitudinal direction, and said vertically extending edge faces of said lugs and said recesses are positioned in abutting engagement so as to prevent motion between said bulkheads in a side-to-side direction.
Claim 3
Dependent Claim
27 words
The segmented boat of claim 1, wherein said engagement means further comprises: means for preventing upper edges of said bulkheads from spreading apart in said longitudinal direction.
Claim 4
Dependent Claim
38 words
The segmented boat of claim 2, wherein said means for preventing said upper edges from spreading apart comprises: at least one bolt for passing through cooperating bores in said first and second bulkheads proximate said upper edges thereof.
Claim 5
Dependent Claim
47 words
The segmented boat of claim 2, wherein said means for preventing said upper edges from spreading apart comprises: a channel member configured to fit over said upper edges of said bulkheads and having depending flange portions for fitting against other surfaces of said first and second bulkheads.
Claim 6
Dependent Claim
57 words
The segmented boat of claim 4, wherein said lugs and said recesses extend continuously to upper edges of said first and second bulkheads, so that upper edges of said faces of said lugs and recesses, and of said flat areas on said bulkheads, form an interlocking zigzag pattern along said upper edges of said bulkheads when joined.
