Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
102 words
An amusement device comprising: a generally spherically shaped hollow shell structure having an interior sufficiently large to accommodate a human being including hatch means to permit ingress and egress from the interior of the shell structure; a frame having an equilateral triangular ground plan base with upstanding leg portions from the apex of each base angle which converge to a common connection over the shell structure; inverted castor means carried by the base frame at each of the three apexes thereof which castor means rotatably support the said shell structure for free rotation about the three mutually perpendicular axes of the shell.
Claim 2
Dependent Claim
102 words
