Abstract
Abstract A wind-scoop for small boats has a collapsible framework of resiliant bent wire members, over which a dome-shaped fabric cover member is received in form fitting relation, one side only of which cover member is air permeable for scooping wind to be directed below deck. The bent wire members of the framework, at their lower ends, are provided with radially outwardly-directed hook means for releasable attachment with respect to the peripheral edge of a deck through opening.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
174 words
A collapsible wind-scoop for releasable attachment over a through opening in the deck of a small boat comprising, in combination, a resilient framework of symmetrical dome-shaped configuration, said framework having an apex at the upper end thereof and a base portion at the lower end thereof, a flexible cover member shaped to fit over and confirm with said resilient framework, between said upper and lower ends thereof, one half-section of said cover member defined by a plane including the axis of symmetry of said resilient framework and being not air permeable and the other half-section being air permeable, and means at the lower end of said dome-shaped framework for releasable attachment with respect to marginal edge portions of a boat deck opening, said resilient framework comprising a pair of bent wire members substantially symmetrical about an axis of generation and crossing at their apices, and means for releasably inter-securing said bent wire members at their apices, said releasable attachment means comprising radially outwardly open hook portions bent in the ends of said wire members.
Claim 2
Dependent Claim
174 words
A collapsible wind-scoop for releasable attachment over a through opening in the deck of a small boat comprising, in combination, a resilient framework of symmetrical dome-shaped configuration, said framework having an apex at the upper end thereof and a base portion at the lower end thereof, a flexible cover member shaped to fit over and confirm with said resilient framework, between said upper and lower ends thereof, one half-section of said cover member defined by a plane including the axis of symmetry of said resilient framework and being not air permeable and the other half-section being air permeable, and means at the lower end of said dome-shaped framework for releasable attachment with respect to marginal edge portions of a boat deck opening, said resilient framework comprising a pair of bent wire members substantially symmetrical about an axis of generation and crossing at their apices, and means for releasably inter-securing said bent wire members at their apices, said releasable attachment means comprising radially outwardly open hook portions bent in the ends of said wire members.
Claim 3
Dependent Claim
53 words
A collapsible wind-scoop as defined in claim 1, wherein said means for releasably inter-securing said bent wire members at their apices comprises a pair of complementary, reversely-bent, arcuate recesses of slightly greater than 180 circular degree extent at the apices of one each of said bent wire members to provide an inter-connecting detent.
Claim 4
Dependent Claim
27 words
A collapsible wind-scoop as defined in claim 2, including means at the open end of said flexible cover member for removable securement with respect to said framework.
Claim 5
Dependent Claim
26 words
A collapsible wind-scoop as defined in claim 3, wherein said cover member securement means comprises an elastic band surrounding the peripheral opening of said cover member.
