Abstract
Abstract A toy projectile comprising an upper stage having a segmented, tubular rocket-simulating body in which segments or vanes are hinged and formed to provide a rocket vehicle-like configuration in the closed condition and, upon opening, provide radially disposed air foil members which operate in the manner of an autogyro or helicopter to provide gyro rotation of the vehicle for slow descent after it has reached its apogee. The lower stage comprises a tube which is slidably and frictionally receivable within a lower adaptor portion on the upper stage so as to removably mount the lower stage on the upper stage. A solid grain propellant engine, including a thrust charge, delay and separation charge, is mounted in the tube of the lower stage. The lower stage serves to retain the segments or vanes in a closed condition before separation of the upper and lower stages by the separation charge within the lower stage.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
184 words
A toy projectile having an upper stage and a lower stage, said upper stage comprising a plurality of vanes movably mounted thereon for movement between a closed, substantially longitudinally extending position and an open, substantially radially outwardly extending position, means for biasing said vanes to said open position, and an adaptor portion disposed on the lower end of said upper stage and comprising a downwardly opening tubular section; and said lower stage comprising a first tubular portion having an upper end adapted to be received within said tubular section of said adaptor portion to removably secure said lower stage to said upper stage, means mounted on said first tubular portion for engaging the lower portions of said vanes to retain them in said closed position when said upper and lower stages are removably connected, and means mounted in the lower end of said first tubular portion for propelling said projectile and for separating said upper and lower stages to enable the lower portions of said vanes to move away from said retaining means, whereby said biasing means moves said vanes to said open position.
Claim 2
Dependent Claim
184 words
A toy projectile having an upper stage and a lower stage, said upper stage comprising a plurality of vanes movably mounted thereon for movement between a closed, substantially longitudinally extending position and an open, substantially radially outwardly extending position, means for biasing said vanes to said open position, and an adaptor portion disposed on the lower end of said upper stage and comprising a downwardly opening tubular section; and said lower stage comprising a first tubular portion having an upper end adapted to be received within said tubular section of said adaptor portion to removably secure said lower stage to said upper stage, means mounted on said first tubular portion for engaging the lower portions of said vanes to retain them in said closed position when said upper and lower stages are removably connected, and means mounted in the lower end of said first tubular portion for propelling said projectile and for separating said upper and lower stages to enable the lower portions of said vanes to move away from said retaining means, whereby said biasing means moves said vanes to said open position.
Claim 3
Dependent Claim
50 words
The toy projectile of claim 1 wherein said adaptor portion comprises an upper substantially cylindrical section and a lower substantially frusto-conical section, and wherein the upper end of said first tubular portion is slidably receivable within said upper cylindrical section to frictionally retain said lower stage on said upper stage.
Claim 4
Dependent Claim
64 words
The toy projectile of claim 1 wherein said means to retain said vanes in said closed position comprises a second tubular portion secured to and surrounding the lower end of said first tubular portion, the lower ends of said vanes being receivable within said second tubular portion when said upper and lower stages are removably connected to retain said vanes in said closed position.
Claim 5
Dependent Claim
60 words
The toy projectile of claim 1 wherein said means to retain said vanes in said closed position comprises a ring secured to and surrounding the lower end of said first tubular portion, the lower ends of said vanes being receivable within said ring when said upper and lower stages are removably connected to retain said vanes in said closed position.
Claim 6
Dependent Claim
57 words
The toy projectile of claim 1 wherein said means to retain said vanes in said closed position comprises a plurality of fins secured to the lower end of said first tubular portion, said fins having upwardly opening slots positioned to receive the lower ends of said vanes therein when said upper and lower stages are removably connected.
Claim 7
Dependent Claim
23 words
The toy projectile of claim 1 wherein a plurality of stabilizing fins are connected to the lower end of said first tubular portion.
Claim 8
Dependent Claim
15 words
The toy projectile of claim 1 wherein said propulsion means comprises a solid propellant engine.
Claim 9
Dependent Claim
25 words
The toy projectile of claim 7 wherein said engine comprises a thrust charge, delay means, and a charge for separating said upper and lower stages.
Claim 10
Dependent Claim
17 words
The toy projectile of claim 1 wherein said vanes are substantially symmetrically disposed around said upper stage.
Claim 11
Dependent Claim
38 words
The toy projectile of claim 1 wherein said upper stage further comprises a base and a nose cone secured to the upper end of said base, said adaptor portion being secured to the lower end of said base.
