Soft flying game disc
First Claim
1. A soft flying game disc having air flow path determined lift and flight stability characteristics, said disc comprising a limp, generally circular fabric, and means defining a stiffened annular locus extending circularly and inward of the fabric peripheral edge margin to form a central air foil structure circumscribed by said means and peripheral spoiler skirt structure radially beyond said means, whereby said air flow path is increased and lift and flight stability characteristics of the disc correspondingly enhanced.

7. A soft flying game disc having air flow path determined lift and flight stability characteristics, said disc comprising a limp, generally circular fabric member having a first diameter, a relatively stiffer, separately formed, annular element having a second, lesser diameter, coaxial with and secured to said fabric member to delimit and differentially support central and perimetrical fabric member portions of relative size determined by said first and second diameters, said central portion being relatively less supported and more airstream displacement responsive during disc flight in air foil-structure defining relation;
- said perimetrical portion being relatively more supported and less airstream displacement responsive in spoiler skirt structure defining relation relative to said air foil;
whereby the disc diametrical dimension is effectively increased beyond the annular element diameter, increasing correspondingly the peripheral air flow path over said disc, the flow path determined lift and flight stability characteristics being thus enhanced. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
- said perimetrical portion being relatively more supported and less airstream displacement responsive in spoiler skirt structure defining relation relative to said air foil;

20. A soft flying game disc having air flow path determined lift and flight stability characteristics, said disc including a fabric member comprising multiple layers of generally circular, limp cloth pieces having a common first diameter, a relatively stiffer, separately formed, dimensionally resilient and circumferentially integral toroidal element wrapped in a further cloth piece, and said element having a second, lesser diameter, said element being coaxially secured to said fabric member by sewing its cloth wrapper peripherially to said circular cloth pieces, to delimit and differentially support a fabric member central portion sized to be relatively less supported and baggy inward of said element and a fabric member perimetrical portion outward of said element sized to be relatively more supported and stiffer and further stiffened by said element cloth wrapper being sewn thereto;
- said central portion having relatively greater airstream displacement response during disc flight in air foil structure defining relation;
said perimetrical portion having relatively lesser airstream displacement response during disc flight in spoiler skirt structure defining relation, whereby the disc diametrical dimension is effectively increased beyond the toroidal element diameter, increasing correspondingly the peripheral air flow path over said disc, the flow path determined lift and flight stability characteristics being thus enhanced.
- said central portion having relatively greater airstream displacement response during disc flight in air foil structure defining relation;
