| Abstract: |
Disclosed are improved, unpredictably tumbleable capsule structures that are loosely internally provided with weighty rollable spherical ball, whereby such improved capsule is adapted to unpredictably compete with identical tumbleable capsule structures along downwardly-inclined ramps. Such improved tumbleable capsule structures are preferably circularly symmetrical about a directionally longitudinally extending horizontal central-axis and also about a central vertical-plane, and having uniquely ratioed capsule housing and interior rollable sphere interdimensional parameter values. Ancillarily disclosed are improved topically-textured and judicially-inclined racing ramps and ramp starting gates, all devoted toward enhancing unpredictable racing capability for a plurality of identically constructed internally-weighted tumbleable capsule structures along downwardly-extending ramps.

We claim:
1. Tumbleable Capsule Structure adapted to unpredictably compete with identical tumbleable capsule structures downwardly along a selectable ramp, and each said tumbleable capsule structure extending generally similarly circularly about a directionally longitudinally extending horizontal central-axis and also bi-directionally longitudinally from a capsule vertical-plane that perpendicularly intersects said horizontal central-axis, and said tumbleable capsule structure comprising:
- (A) a uniformly thin-walled housing member comprising:
- (A1) similarly thin-walled and longitudinally bi-directional central-zones flanking said vertical-plane at an inside-diameter value from said horizontal central-axis at said vertical-plane;
- (A2) each said uniformly thin-walled central-zone, longitudinally remote from said vertical-plane, being provided with similarly thin-walled end-caps respectively endwardly converging toward said horizontal central-axis, whereby said housing member has a longitudinal-length central-axis value that bears a ratio within the range of substantially 11/3 to 2 as compared to said inside-diameter value; and
- (A3) a shoulder member circularly concentrically surrounding said central-axis outwardly beyond the thin-walled housing central-zone along the vertical-plane thereof, and having an outward shoulder-diameter that bears a ratio within the range of substantially 1.05 to 1.50 as compared to said housing inside-diameter value; and
- (B) a weighty spherical ball that is freely rollably disposed within said housing and having a ball-diameter value representing a ratio within the range of substantially 0.55 to 0.99 as compared to said housing inside-diameter value, and said spherical ball having the capability of rolling longitudinally bi-directionally along said central-axis and thereby abuttably at said housing end-caps.
