Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
246 words
A rotating kite comprising: an elongated rigid control arm having a first free end and a second free end, said control arm having pitched blades to interact with the air tending to cause rotation of said control arm in a preferred direction of rotation; means for affixing a kite string to said first and second free ends of said control arm; a spindle rotatably affixed to the central portion of said control arm, said spindle being rotatable around the longitudinal axis thereof, said longitudinal axis of said spindle being substantially normal to the longitudinal axis of said control arm; a plurality of rigid air engaging arms each fixedly secured on a first end thereof to said spindle and being radially disposed therefrom, the longitudinal axis of each of said air engaging arms being substantially perpendicular to said longitudinal axis of said spindle; a ring-like element dimensioned to enclose the second free ends of each of said air engaging arms, said second free ends each being fixedly secured thereto, and a membrane fixedly secured to the free edges of said ring-like element farthermost from said control arm, said membrane covering the area enclosed by said ring-like element, said membrane having a plurality of slots located therein, each of said plurality of slots being adjacent one of each of said plurality of air engaging arms, said slots permitting air currents imparting force on said air engaging arms to pass therethrough, said air currents causing said spindle to rotate.
Claim 2
Dependent Claim
246 words
A rotating kite comprising: an elongated rigid control arm having a first free end and a second free end, said control arm having pitched blades to interact with the air tending to cause rotation of said control arm in a preferred direction of rotation; means for affixing a kite string to said first and second free ends of said control arm; a spindle rotatably affixed to the central portion of said control arm, said spindle being rotatable around the longitudinal axis thereof, said longitudinal axis of said spindle being substantially normal to the longitudinal axis of said control arm; a plurality of rigid air engaging arms each fixedly secured on a first end thereof to said spindle and being radially disposed therefrom, the longitudinal axis of each of said air engaging arms being substantially perpendicular to said longitudinal axis of said spindle; a ring-like element dimensioned to enclose the second free ends of each of said air engaging arms, said second free ends each being fixedly secured thereto, and a membrane fixedly secured to the free edges of said ring-like element farthermost from said control arm, said membrane covering the area enclosed by said ring-like element, said membrane having a plurality of slots located therein, each of said plurality of slots being adjacent one of each of said plurality of air engaging arms, said slots permitting air currents imparting force on said air engaging arms to pass therethrough, said air currents causing said spindle to rotate.
Claim 3
Dependent Claim
56 words
A rotating kite as claimed in claim 1, wherein said affixing means comprises a pair of hook eyes fixedly secured to said first and second free ends of said longitudinal rigid control arm, one of said hooks fixedly secured to said first free end, the other of said hooks fixedly secured to said second free end.
Claim 4
Dependent Claim
63 words
A rotating kite as claimed in claim 1, wherein said spindle is rotatably affixed to said control arm by an axle passing through and dimensioned to journal with a longitudinal aperture located in said spindle, said axle fixedly secured on one end thereof to said control arm, the other end of said axle providing a lip to prevent said spindle from disengaging therefrom.
Claim 5
Dependent Claim
31 words
A rotating kite as claimed in claim 1, wherein each of said plurality of air engaging arms are pitched about said longitudinal axes thereof to increase engagement with said air currents.
Claim 6
Dependent Claim
23 words
A rotating kite as claimed in claim 4, wherein all of said plurality of air engaging arms are pitched in the same direction.
Claim 7
Dependent Claim
25 words
A rotating kite as claimed in claim 1, further comprising a kite tail fixedly secured to one of said free ends of said control arm.
Claim 8
Dependent Claim
28 words
A rotating kite as claimed in claim 1, wherein each of said plurality of air engaging arms is equidistant from an adjacent one of said air engaging arms.
