Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
78 words
A controlled motion amusement device comprising: base means, a substantially rigid top seat surface and a resilient bellows connecting said top surface to said base means whereby said top surface in response to a force thereon is capable of reciprocal motion in a family of paths away from vertical about a full circle, said base means, bellows, and top surface comprising a single integral molded article, and said bellows having a constricted valved orifice communicating with the atmosphere.
Claim 2
Dependent Claim
78 words
A controlled motion amusement device comprising: base means, a substantially rigid top seat surface and a resilient bellows connecting said top surface to said base means whereby said top surface in response to a force thereon is capable of reciprocal motion in a family of paths away from vertical about a full circle, said base means, bellows, and top surface comprising a single integral molded article, and said bellows having a constricted valved orifice communicating with the atmosphere.
Claim 3
Dependent Claim
30 words
A device according to claim 1 in which the bellows has convolutions of a depth and number that the family of paths are no greater than approximately 45* from vertical.
Claim 4
Dependent Claim
31 words
A device according to claim 2 in which the bellows has convolutions of a depth no greater than approximately 40 percent of the total of the bellows to its outside dimension.
Claim 5
Dependent Claim
34 words
