Abstract
Abstract A foldable wind-resistant umbrella having a top formed from a plurality of separate vanes which can lift to dissipate wind forces. The vanes are mounted over a collapsible frame which permits the umbrella to be folded. The umbrella may be rotatably supported on a pole to enhance its wind dissipating characteristics and may also be provided with interchangeable decorative caps to permit its use in varied decorative schemes.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
138 words
A foldable wind-resistant umbrella comprising, in combination: A. an umbrella pole structure; B. a plurality of vanes each having an apex; a base portion and two longitudinal edges; 1. said vanes being adjacently mounted at their respective apexes for pivotal movement at least toward the axis of said pole structure, and arranged to fan out in serially overlapping relationship to form an umbrella top; C. frame means for supporting said umbrella top in an open position; 1. each said vane being secured to said frame means along one said longitudinal edge with the other longitudinal edge of each vane remaining free and overlapping the fixed longitudinal edge of the next adjacent vane; and 2. said frame means being collapsible to pivot said vanes toward the axis of said pole structure whereby said umbrella top assumes a folded position.
Claim 2
Dependent Claim
138 words
A foldable wind-resistant umbrella comprising, in combination: A. an umbrella pole structure; B. a plurality of vanes each having an apex; a base portion and two longitudinal edges; 1. said vanes being adjacently mounted at their respective apexes for pivotal movement at least toward the axis of said pole structure, and arranged to fan out in serially overlapping relationship to form an umbrella top; C. frame means for supporting said umbrella top in an open position; 1. each said vane being secured to said frame means along one said longitudinal edge with the other longitudinal edge of each vane remaining free and overlapping the fixed longitudinal edge of the next adjacent vane; and 2. said frame means being collapsible to pivot said vanes toward the axis of said pole structure whereby said umbrella top assumes a folded position.
Claim 3
Dependent Claim
29 words
a first plurality of support struts pivotally connected to said hinge plate for movement at least toward the axis of said pole structure, and projecting in sunburst fashion therefrom;
Claim 4
Dependent Claim
29 words
a first plurality of support struts pivotally connected to said hinge plate for movement at least toward the axis of said pole structure, and projecting in sunburst fashion therefrom;
Claim 5
Dependent Claim
12 words
bearing means at two spaced positions on said main support pole; and
Claim 6
Dependent Claim
12 words
bearing means at two spaced positions on said main support pole; and
Claim 7
Dependent Claim
73 words
A foldable wind-resistant umbrella as defined in claim 1 wherein said frame means includes a flexible support ring underlying said umbrella top, the fixed longitudinal edge of each said vane being secured to said flexible support ring whereby each said vane is fixed in a predetermined position when the umbrella is opened and the vanes may increasingly overlap as the frame is collapsed to permit said umbrella top to assume a folded position.
Claim 8
Dependent Claim
24 words
said frame means being collapsible to pivot said vanes toward the axis of said pole structure whereby said umbrella top assumes a folded position.
Claim 9
Dependent Claim
24 words
said frame means being collapsible to pivot said vanes toward the axis of said pole structure whereby said umbrella top assumes a folded position.
Claim 10
Dependent Claim
11 words
a flexible support ring secured to said first plurality of struts;
Claim 11
Dependent Claim
11 words
a flexible support ring secured to said first plurality of struts;
Claim 12
Dependent Claim
20 words
a rotatable hollow beam telescopically mounted on said main support pole between said bearing means; B. a collapsible frame comprising;
Claim 13
Dependent Claim
20 words
a rotatable hollow beam telescopically mounted on said main support pole between said bearing means; B. a collapsible frame comprising;
Claim 14
Dependent Claim
72 words
A foldable wind-resistant umbrella as defined in claim 2 wherein said frame means further comprises: A. means forming a hinge plate mounted on said pole structure with said vanes being pivotally connected thereto; B. a first plurality of support struts pivotally connected to said hinge plate for movement at least toward the axis of said pole structure, and projecting in sunburst fashion adjacent the underside of said umbrella top for support thereof;
Claim 15
Dependent Claim
10 words
a spider slidably mounted on said rotatable hollow beam; and
Claim 16
Dependent Claim
10 words
a spider slidably mounted on said rotatable hollow beam; and
Claim 17
Dependent Claim
49 words
A foldable wind-resistant umbrella as defined in claim 3 and including a plurality of spacers extending between pairs of said first plurality of support struts, each said spacer being disengageable from at least one strut of said pair to permit the collapsing of said frame to a folded position.
Claim 18
Dependent Claim
30 words
A foldable wind-resistant umbrella as defined in claim 3 including means for locking said spider in at least one position on said pole structure corresponding to an open umbrella position.
Claim 19
Dependent Claim
34 words
a second plurality of struts pivotally connected to said spider at one end and projecting in sunburst fashion therefrom to pivotal connections on said first plurality of support struts; C. an umbrella top comprising:
Claim 20
Dependent Claim
34 words
a second plurality of struts pivotally connected to said spider at one end and projecting in sunburst fashion therefrom to pivotal connections on said first plurality of support struts; C. an umbrella top comprising:
Claim 21
Dependent Claim
28 words
A foldable wind-resistant umbrella as defined in claim 3 including substantially universal pivotal joints connecting both said vanes and said first plurality of struts to said hinge plate.
Claim 22
Dependent Claim
82 words
A foldable wind-resistant umbrella as defined in claim 2 wherein said flexible support ring comprises a length of flexible cable secured to said first plurality of struts, each said vane being secured to said flexible cable by a fastener comprising a headed bolt having a slotted shank which passes through the vane to the underside thereof, said flexible cable extending through said slot and a nut threadedly secured to said shank and clamping said flexible cable against the underside of said vane.
Claim 23
Dependent Claim
21 words
