Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
245 words
A balloon having an envelope and a basket with a deflation port formed in said envelope comprising an opening formed in said envelope, a deflation panel attached to said envelope to cover said opening, a line attached to said deflation panel and extending to said basket so as to selectively allow said deflation panel to move relative to said opening to cover it by varying amounts, wherein said opening in said envelope is circular and is formed in an upper portion thereof, wherein said deflation panel is cylindrical in shape and has its lower edge connected to said envelope about said opening and said line is engageable with the upper edge of said cylindrical deflation panel and is arranged to open and close it, wherein said upper edge of said cylindrical deflation panel is formed with a plurality of spaced opening through which said line extends so as to open it and close it like a draw string, comprising a plurality of pulleys attached to said balloon so as to guide said line, wherein said plurality of spaced openings are formed by rings attached about said upper edge of said cylindrical deflation panel, and wherein a holding member is connected to said line and second and third lines extending downwardly from said holding member such that said second line is attached to said balloon where it is available for manual operation, and an automatic disconnect connected to said third line and operable from said basket.
Claim 2
Dependent Claim
245 words
A balloon having an envelope and a basket with a deflation port formed in said envelope comprising an opening formed in said envelope, a deflation panel attached to said envelope to cover said opening, a line attached to said deflation panel and extending to said basket so as to selectively allow said deflation panel to move relative to said opening to cover it by varying amounts, wherein said opening in said envelope is circular and is formed in an upper portion thereof, wherein said deflation panel is cylindrical in shape and has its lower edge connected to said envelope about said opening and said line is engageable with the upper edge of said cylindrical deflation panel and is arranged to open and close it, wherein said upper edge of said cylindrical deflation panel is formed with a plurality of spaced opening through which said line extends so as to open it and close it like a draw string, comprising a plurality of pulleys attached to said balloon so as to guide said line, wherein said plurality of spaced openings are formed by rings attached about said upper edge of said cylindrical deflation panel, and wherein a holding member is connected to said line and second and third lines extending downwardly from said holding member such that said second line is attached to said balloon where it is available for manual operation, and an automatic disconnect connected to said third line and operable from said basket.
Claim 3
Dependent Claim
19 words
A balloon according to claim 1 wherein said automatic disconnect comprises a pull pin for releasing said third line.
Claim 4
Dependent Claim
188 words
A balloon having an envelope and a basket with a deflation port formed in said envelope comprising a circular opening formed in the upper portion of said envelope, a deflation panel of generally cylindrical shape with its lower edge attached to said envelope about said circular opening, a plurality of first rings attached to said deflation panel about its upper edge, a second ring firmly attached to said deflation panel, first and second flexible cords with first ends attached to said second ring and extending in opposite direction through said plurality of first rings to the side of said opening opposite said second ring, a pair of pulleys attached to said deflation panel at the upper edge thereof, opposite said second ring and said first and second flexible cords passing therethrough, means joining the second ends of said first and second flexible cords below said pair of pulleys, and a third cord with a first end attached to said means joining said first and second flexible cords and extending down to said basket, and means for detachable connecting the second end of said third cord to said basket.
Claim 5
Dependent Claim
188 words
