Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
129 words
A toy airplane simulating a helicopter comprising means for maintaining said toy airplane in the air and in a floating position by virtue of the air currents, said means comprising an elongated body having a string attached thereto, and a substantially horizontally disposed rotating member rotatably mounted to and above said body, said rotating member being of substantially flat, kite-like construction, and having a centrally disposed opening permitting air currents to flow therethrough from below to above said member, thereby minimizing the buffeting effects of said air currents and effective greater stabilization of the toy in the air, said rotating member having radially extending struts, and paddle members at the ends of at least some of said struts cooperating with said air currents to effect rotation of said member.
Claim 2
Dependent Claim
129 words
A toy airplane simulating a helicopter comprising means for maintaining said toy airplane in the air and in a floating position by virtue of the air currents, said means comprising an elongated body having a string attached thereto, and a substantially horizontally disposed rotating member rotatably mounted to and above said body, said rotating member being of substantially flat, kite-like construction, and having a centrally disposed opening permitting air currents to flow therethrough from below to above said member, thereby minimizing the buffeting effects of said air currents and effective greater stabilization of the toy in the air, said rotating member having radially extending struts, and paddle members at the ends of at least some of said struts cooperating with said air currents to effect rotation of said member.
Claim 3
Dependent Claim
170 words
A toy airplane simulating a helicopter comprising means for maintaining said toy airplane in the air and in a floating position by virtue of the air currents, said means comprising an elongated body having a string attached thereto, and a substantially horizontally disposed rotating member rotatably mounted to and above said body, said rotating member being of substantially flat, kite-like construction, and having a centrally disposed opening permitting air currents to flow therethrough from below to above said member, thereby minimizing the buffeting effects of said air currents and effecting greater stabilization of the toy in the air, said rotating member having radially extending struts, rod members secured to the ends of at least some of said struts to define a generally T-shaped configuration, said rod members being tilted somewhat out of the plane of said rotating member, the material spanning said rotating member being attached to said struct and rod members whereby to provide slightly twisted portions which cooperate with said air currents to effect rotation of said member.
Claim 4
Dependent Claim
170 words
A toy airplane simulating a helicopter comprising means for maintaining said toy airplane in the air and in a floating position by virtue of the air currents, said means comprising an elongated body having a string attached thereto, and a substantially horizontally disposed rotating member rotatably mounted to and above said body, said rotating member being of substantially flat, kite-like construction, and having a centrally disposed opening permitting air currents to flow therethrough from below to above said member, thereby minimizing the buffeting effects of said air currents and effecting greater stabilization of the toy in the air, said rotating member having radially extending struts, rod members secured to the ends of at least some of said struts to define a generally T-shaped configuration, said rod members being tilted somewhat out of the plane of said rotating member, the material spanning said rotating member being attached to said struct and rod members whereby to provide slightly twisted portions which cooperate with said air currents to effect rotation of said member.
