Abstract

Abstract Canoe toting apparatus which enables a single individual to manually transport a canoe or similar marine craft over reasonable distances comprises a pair of wheels rotatably mounted on opposite ends of an adjustable width axle and a adjustable-width gunwale clamp whcih extends parallel to the axle and is attached at each end to one of the axle ends by clamping rods. The rods are threaded and accept nuts which can be tightened against the gunwale clamp to secure the canoe against the axle. An optional keel guide, contoured for a conventional V-shaped keel, attaches to the top surface of the axle to accommodate canoes having keels.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 262 words
Apparatus for transporting a canoe or similar marine craft having gunwales, said apparatus comprising: an axle, said axle having an adjustable width to accommodate marine craft of varying widths, said axle having a first and a second end and a top surface against which said marine craft rests; a pair of wheels, one of said pair of wheels being perpendicularly and rotatably mounted on said first axle end and the other of said pair of wheels being perpendicularly and rotatably mounted on said second axle end; a gunwale clamp beam having an adjustable length and extending parallel to said axle for engaging said gunwales, said gunwale clamp having a first end and a second end; a pair of rigid clamping rods; first bolt means for pivotally attaching a first of said pair of clamping rods to said first axle end so that said first of said pair of clamping rods is movable in two dimensions with respect to said axle; second bolt means for pivotally attaching a second of said pair of clamping rods to said second axle and so that said second of said pair of clamping rods is movable in two dimensions with respect to said axle, said first and second clamping rods extending through said first and second gunwale clamp ends respectively; and means for adjustable securing said first clamping rod to said first gunwale clamp end and said second clamping rod to said second gunwale clamp and so that the height of said clamp beam from said axle can be adjusted to accommodate marine crafts of varying heights.
Claim 2
Dependent Claim 262 words
Apparatus for transporting a canoe or similar marine craft having gunwales, said apparatus comprising: an axle, said axle having an adjustable width to accommodate marine craft of varying widths, said axle having a first and a second end and a top surface against which said marine craft rests; a pair of wheels, one of said pair of wheels being perpendicularly and rotatably mounted on said first axle end and the other of said pair of wheels being perpendicularly and rotatably mounted on said second axle end; a gunwale clamp beam having an adjustable length and extending parallel to said axle for engaging said gunwales, said gunwale clamp having a first end and a second end; a pair of rigid clamping rods; first bolt means for pivotally attaching a first of said pair of clamping rods to said first axle end so that said first of said pair of clamping rods is movable in two dimensions with respect to said axle; second bolt means for pivotally attaching a second of said pair of clamping rods to said second axle and so that said second of said pair of clamping rods is movable in two dimensions with respect to said axle, said first and second clamping rods extending through said first and second gunwale clamp ends respectively; and means for adjustable securing said first clamping rod to said first gunwale clamp end and said second clamping rod to said second gunwale clamp and so that the height of said clamp beam from said axle can be adjusted to accommodate marine crafts of varying heights.
Claim 3
Dependent Claim 29 words
The canoe transporting apparatus of claim 1 further comprising a guide member attachable adjacent said axle top surface for accommodating the keel of a canoe or similar marine craft.
Claim 4
Dependent Claim 27 words
The canoe transporting apparatus of claim 2 whereby said guide member has a substantially V-shaped guide for receiving the keel of a canoe or similar marine craft.
Claim 5
Dependent Claim 271 words
Apparatus for transporting a canoe or similar marine craft comprising: an axle, having an outer axle member and an inner axle member, said inner axle member having the same cross-sectional shape as said outer axle member but with a smaller cross-sectional size so that said inner axle member slides within said outer axle member forming a telescoping axle with length adjustable over a predetermined range, said axle having a first and a second end and a top surface against which said marine craft or canoe rests; a pair of wheels, one of said pair of wheels being perpendicularly and rotatably mounted on said first axle end and the other of said pair of wheels being perpendicularly and rotatably mounted on said second axle end; a gunwale clamp having a first end, a second end, an outer clamp member and an inner clamp member, said inner clamp member having the same cross-sectional shape as said outer clamp member but with a smaller cross-sectional size so that said inner clamp member slides within said outer clamp member forming a telescoping clamp with length adjustable over a predetermined range; and a pair of threaded clamping rods pivotally mounted to said axle, one of said pair of rods being attached to said first axle end and extending through said first gunwale clamp end and the other of said pair of rods being attached to said second axle end and extending through said second gunwale clamp end, said clamping rods having clamping nuts threaded thereon, which nuts bear against said gunwale clamp and cause said gunwale clamp to bear against the gunwales of said marine craft
Claim 6
Dependent Claim 271 words
Apparatus for transporting a canoe or similar marine craft comprising: an axle, having an outer axle member and an inner axle member, said inner axle member having the same cross-sectional shape as said outer axle member but with a smaller cross-sectional size so that said inner axle member slides within said outer axle member forming a telescoping axle with length adjustable over a predetermined range, said axle having a first and a second end and a top surface against which said marine craft or canoe rests; a pair of wheels, one of said pair of wheels being perpendicularly and rotatably mounted on said first axle end and the other of said pair of wheels being perpendicularly and rotatably mounted on said second axle end; a gunwale clamp having a first end, a second end, an outer clamp member and an inner clamp member, said inner clamp member having the same cross-sectional shape as said outer clamp member but with a smaller cross-sectional size so that said inner clamp member slides within said outer clamp member forming a telescoping clamp with length adjustable over a predetermined range; and a pair of threaded clamping rods pivotally mounted to said axle, one of said pair of rods being attached to said first axle end and extending through said first gunwale clamp end and the other of said pair of rods being attached to said second axle end and extending through said second gunwale clamp end, said clamping rods having clamping nuts threaded thereon, which nuts bear against said gunwale clamp and cause said gunwale clamp to bear against the gunwales of said marine craft
Claim 7
Dependent Claim 29 words
The canoe transporting apparatus of claim 4 further comprising a guide member attachable adjacent said axle top surface for accommodating the keel of a canoe or similar marine craft.
Claim 8
Dependent Claim 27 words
The canoe transporting apparatus of claim 5 whereby said guide member has a substantially V-shaped guide for receiving the keel of a canoe or similar marine craft.
Claim 9
Dependent Claim 33 words
The canoe transporting apparatus of claim 6 wherein said axle can be fixed at a predetermined width by means of a bolt passing through said inner axle member and said outer axle member.
Claim 10
Dependent Claim 34 words
The canoe transporting apparatus of claim 7 wherein said gunwale clamp can be fixed at a predetermined width by means of a bolt passing through said inner clamp member and said outer clamp member.
Claim 11
Dependent Claim 26 words
The canoe transporting apparatus of claim 8 wherein said clamping rods are attached to said first and said second axle ends by means of interlinked loops
Claim 12
Dependent Claim 37 words
The canoe transporting apparatus of claim 9 wherein said axle top surface, said gunwale clamp and said keel guide are covered with a resilient material to reduce abrasion to a marine craft carried by said transporting apparatus.
