Abstract

Abstract An inflatable boat has a pair of elongated inflatable side portions extending lengthwise of the boat, disposed within an envelope that can be opened and closed by longitudinally-extending openings on its outer side, to permit insertion and removal of inflatable chambers. The margins of the envelope openings are maintained closed by interfitting loops, each loop receiving a slotted pin with the head and tail of the pin projecting from opposite sides of the loop, so that the pins of the loops associated with one margin of the opening interfere with the heads and tails of the pins projecting from the loops associated with the other margin of the opening, thereby to hold the margins together. A rigid panel at the stern of the boat supports an outboard motor, and is detachably secured between the side members by special screw assemblies. At the prow of the boat, relatively vertically swingable panels provide a deck in one position and the support for a short ladder in another position.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 114 words
An inflatable boat comprising a pair of elongated side portions of flexible material with at least one inflatable air chamber within each side portion, and at the stern of the boat a rigid panel for supporting an outboard motor, and screw-threaded means acting between the flexible material and the panel to hold said side portions at opposite ends of said panel, said screw-threaded means comprising at least one arcuate strap, means mounting said arcuate strap on said side portion against rotation relative to said side portion, said screw means including screws that project radially outwardly through said flexible material from said at least one strap, and means on said panel to receive said screws.
Claim 2
Dependent Claim 114 words
An inflatable boat comprising a pair of elongated side portions of flexible material with at least one inflatable air chamber within each side portion, and at the stern of the boat a rigid panel for supporting an outboard motor, and screw-threaded means acting between the flexible material and the panel to hold said side portions at opposite ends of said panel, said screw-threaded means comprising at least one arcuate strap, means mounting said arcuate strap on said side portion against rotation relative to said side portion, said screw means including screws that project radially outwardly through said flexible material from said at least one strap, and means on said panel to receive said screws.
Claim 3
Dependent Claim 37 words
A boat as claimed in claim 1, said means on said panel comprising cylindrical blocks whose axes extend lengthwise of the boat and that are rotatable in the panel and have screw-threaded openings for receiving said screws.
Claim 4
Dependent Claim 60 words
A boat as claimed in claim 1, said screw-threaded means comprising holes extending radially through said panel parallel to said screws, said holes terminating in further holes that extend parallel to the length of the boat, and nuts in said further holes which engage on the ends of said screws when said screws are inserted into said radially extending holes.
Claim 5
Dependent Claim 17 words
A boat as claimed in claim 1, said at least one strap comprising a single metal strap.
Claim 6
Dependent Claim 20 words
A boat as claimed in claim 1, said at least one strap comprising a strap individual to each said screw.
