Abstract
Abstract An aerial toy comprising a body having a leading edge and a trailing edge, and comprising a flexible, resilient, thin wall sail or airfoil extending forward from the trailing edge; a relatively thick, relatively rigid peripheral ring at the leading edge, the toy having a ratio of body length to body diameter of between 1:1.25 and 1:1.35; a ratio of body diameter to leading edge thickness of about 30:1; a ratio of ring length to overall body length of about 1:3.66; and a ratio of leading end weight to trailing end weight of 2.2:1.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
224 words
A hand launched aerial toy consisting of a hollow open-ended resilient deformable body including forward and rearward body sections having a diameter greater than its length, said rearward body section constituting a relatively thin walled sail means, said thin walled sail means having a substantially constant thickness said forward body section being substantially axially shorter than said rearward section and of radially thicker construction and configured to define a linear substantially constant interior cross section with said rearward body section, said forward body section being of a greater external diameter than said rearward body section, said toy body being of substantially uniform internal diameter throughout its length, said forward body section including a chamfered leading edge and a diminishing external thickness adjacent the point of interconnection with said rearward body section and including a smooth outer surface to define a total external surface of greater size than said linear substantially constant interior cross section, and wherein said forward body section comprises an external airfoil, and wherein said toy body defines a configuration to create an interior high pressure region and an external low pressure region when launched through the air, and a relative length relationship is established between said forward and rearward body sections to place the longitudinal center of gravity at substantially the point of interconnection between said forward and rearward body sections.
Claim 2
Dependent Claim
