Abstract
Abstract Disclosed is a folding boat useful as a sailboat, motorboat or a rowboat. The boat comprises a boat hull comprising forward and rear shells each having similar flat transverse partitions at their adjacent ends in substantially the midportion of the hull. The partitions are pivotally connected together whereby one of the shells may be pivoted upwardly from a fully extended position to a position overlying the other of the shells. When so folded, the two shells define a closed chamber therebetween and means are secured between the shells when the boat is in the folded position to divide the chamber into upper and lower sections whereby cargo to be stored in the chamber may be segregated between the upper and lower sections. In the unfolded position of the boat, spring-clip means are provided on the partitions to lock the shells together and maintain them in the open position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
174 words
In a folding boat construction, the combination comprising a boat hull comprising a pair of unitary shells, said shells each having similar flat transverse partitions at their adjacent ends in substantially the midportion of said hull, means pivotally connecting said partitions together whereby one of said shells may be pivoted upwardly from a fully extended position to a position overlying the other of said shells, said shells in the folded position of the boat defining a closed chamber therebetween, and removable spring-clip means fitting over said partitions to lock said shells together in the unfolded position thereof to form an open boat, said spring-clip means being of generally U-shaped configuration and having a relatively short web portion and a pair of spaced-apart elongated portions extending from said web portion, said web portion lying in engagement with the upper edges of said partitions in the normal operative position of said spring-clip means and said spacedapart portions of said spring-clip means extending downwardly from said web in engagement with the exposed side surfaces of said partitions.
Claim 2
Dependent Claim
174 words
In a folding boat construction, the combination comprising a boat hull comprising a pair of unitary shells, said shells each having similar flat transverse partitions at their adjacent ends in substantially the midportion of said hull, means pivotally connecting said partitions together whereby one of said shells may be pivoted upwardly from a fully extended position to a position overlying the other of said shells, said shells in the folded position of the boat defining a closed chamber therebetween, and removable spring-clip means fitting over said partitions to lock said shells together in the unfolded position thereof to form an open boat, said spring-clip means being of generally U-shaped configuration and having a relatively short web portion and a pair of spaced-apart elongated portions extending from said web portion, said web portion lying in engagement with the upper edges of said partitions in the normal operative position of said spring-clip means and said spacedapart portions of said spring-clip means extending downwardly from said web in engagement with the exposed side surfaces of said partitions.
Claim 3
Dependent Claim
48 words
In a folding boat construction as defined in claim 1, wherein said partitions have recessed portion extending inwardly from the exposed surfaces thereof and said spaced-apart portions of said spring-clip means each have an inwardly projecting portion adapted to enter and engage a recessed portion in said partitions.
Claim 4
Dependent Claim
22 words
In a folding boat construction as defined in claim 1, wherein said spring-clip means include means for removably securing a seat thereto.
Claim 5
Dependent Claim
114 words
In a folding boat construction as defined in claim 1, wherein each of said shells has side decks extending laterally outwardly adjacent the upper edges of the side walls thereof to define a continuous rubrail extending about the upper periphery of the boat in the unfolded position thereof, one of said side decks on one of said shells having an upstanding endless flangelike portion and the other of said decks on the other of said shells having a continuous upwardly opening channel, said flangelike portion being received in and cooperating with said channel when said boat is in the folded position to provide a weather tight junction along the mating surfaces of said shells.
Claim 6
Dependent Claim
95 words
In a folding boat construction as defined in claim 4, wherein at least one of said decks of one of said shells has a depressed ledge formed on the interior edge thereof which extends about the upper periphery of said one shell, and a horizontal platform is adapted to be mounted on said shoulder with its upper surface being flush with said one deck whereby in the folded position of said boat the other of said decks engages the marginal portions of the upper surface of said platform to secure said platform between said shells.
Claim 7
Dependent Claim
51 words
In a folding boat construction as defined in claim 4, wherein the exposed upper and lower surfaces of said rubrail in the folded position of said boat converge toward said shells to provide clamping surfaces for clamping the boat to a vehicle, whereby the boat may be hauled on a highway.
