Foldable dinghies

Claim 2

A foldable dinghy comprising a frame and a covering of flexible waterproof material therefor, the frame being foldable both transversely and longitudinally for the purpose of storing and transporting the dinghy, wherein the frame comprises a plurality of longitudinally foldable members which, when the dinghy is erected, extend longitudinally of the dinghy, each of said longitudinal members having two hinge means therein defining a central portion and two end portions with the end portions being foldable toward each other about transverse axes through said hinge means; at least one transverse foldable member which, when the dinghy is erected, extends transversely of the dinghy intermediate the ends of the dinghy, and means for maintaining the dinghy erected, said means being releasable to allow said at least one foldable transverse member to be folded, thereby drawing the longitudinal members into parallel contiguous relationship along the central longitudinal axis of the dinghy with the axes of said hinge means substantially aligned so that the foldable longitudinal members may be folded longitudinally.

Claim 3

A foldable dinghy as claimed in claim 1, wherein said foldable transverse member comprises at least two sections hingedly connected together to form a seat when the dinghy is erected.

Claim 4

A foldable dinghy as claimed in claim 2, wherein the dinghy has rowlocks positioned to allow the dinghy to be rowed.

Claim 5

A foldable dinghy as claimed in claim 2, wherein at least one of the seat sections is formed of buoyancy material.

Claim 6

A foldable dinghy as claimed in claim 4, wherein the buoyancy material is self-skinning rigid polyurethane.

Claim 7

A foldable dinghy as claimed in claim 1, wherein these are five said foldable longitudinal members, and the foldable transverse member extends between the two next to outermost longitudinal members.

Claim 8

A foldable dinghy as claimed in claim 6, wherein the means for maintaining the dinghy erected includes strut members pivotally attached to respective ends of said foldable transverse member, each strut member being movable between an inoperative folded position and an operative position in which it is locked relative to the adjacent outermost longitudinal member.

Claim 9

A foldable dinghy as claimed in claim 7, and further comprising a pair of strengthening struts at each end of the dinghy, each of which struts is pivotally attached to the central longitudinal member and releasably engageable with one of the outermost longitudinal members.

Claim 10

A foldable dinghy as claimed in claim 1, wherein there are five said foldable longitudinal members, and the foldable transverse member extends between the two outermost longitudinal members.

Claim 11

A foldable dinghy as claimed in claim 9, wherein the foldable transverse member is supported on struts, each strut extending between and being pivotally attached to the transverse member and a respective intermediate longitudinal member.

Claim 12

A foldable dinghy as claimed in claim 9, wherein the means for maintaining the dinghy extended comprises foldable members capable of maintaining the foldable transverse member extended and in fixed relation relative to the central longitudinal member, thereby maintaining each longitudinal member in its respective erected position.

Claim 13

A foldable dinghy as claimed in claim 1, wherein there are two said foldable transverse members spaced apart longitudinally of the dinghy, at least those portions of the longitudinal members which extend between each transverse member and the adjacent end of the dinghy being foldable longitudinally of the dinghy.

Claim 14

A foldable dinghy as claimed in claim 1, wherein the covering is attached to the frame in a manner which allows the frame to be folded and unfolded without removal of the covering.

Claim 15

A foldable dinghy as claimed in claim 1, wherein the covering is a nylon woven fabric coated with polyvinyl chloride.

Claim 16

A foldable dinghy as claimed in claim 1, wherein a suspended seat of flexible material is provided adjacent at least one end of the dinghy.

Claim 17

A foldable dinghy as claimed in claim 1, wherein the central uppermost portion of the frame at the stern of the dinghy is capable of supporting an outboard motor.

Claim 18

A foldable dinghy comprising a frame and a covering of flexible waterproof material attached to said frame, said frame comprising a plurality of longitudinal members each formed in a U shape; end attachment means for pivotally coupling said members together so that said members are pivotable between a first folded position in which the members lie next to each other in substantially parallel relationship and a second deployed position in which said members define the hull frame of the erected dinghy; each of said longitudinal members further comprising first and second hinge means for dividing said member into a central portion and two end portions, said end portions being swingable toward said central portion and each other; a transverse foldable member extending between the central portions of at least two of said longitudinal members, said transverse member being movable between an extended position when said longitudinal members are deployed and said dinghy is erected, and a folded position in which said longitudinal members are pivoted to said first folded position; and means for releasably locking said transverse member in said extended position, the end portions of said longitudinal members being swingable toward each other only when said transverse member is in said folded position.

Claim 19

A foldable dinghy comprising a frame and a covering of flexible waterproof material attached to said frame, said frame comprising a plurality of longitudinal members each formed in a U shape; end attachment means for pivotally coupling said members together so that said members are pivotable between a first folded position in which the members lie next to each other in substantially parallel relationship and a second deployed position in which said members define the hull frame of the erected dinghy; each of said longitudinal members further comprising first and second hinge means for dividing said member into a central portion and two end portions, said end portions being swingable toward said central portion and each other; a transverse foldable member extending between the central portions of at least two of said longitudinal members, said transverse member being movable between an extended position when said longitudinal members are deployed and said dinghy is erected, and a folded position in which said longitudinal members are pivoted to said first folded position; and means for releasably locking said transverse member in said extended position, the end portions of said longitudinal members being swingable toward each other only when said transverse member is in said folded position.
