Abstract
A clock is provided which is movable so as to maintain an indication of local time constantly in a vertically upward position. A shell bears a plurality of time indicia. A clock motor interior to the shell rotates an eccentric weight about the longitudinal axis of the shell, causing the shell to rotate and roll over a support surface. A pointer attached to the clock motor and opposite the eccentric weight points to the proper local time indicia.
Claims26
A clock, comprising:
- a shell with a convex rolling surface, the shell having a first axis and defining an interior region;
- a motor rotatably attached to said shell along said first axis, said motor having a weight attached in a position which is eccentric with respect to said first axis, wherein rotation of said motor moves said eccentric weight about said axis to effect motion of said shell with respect to a supporting surface;
- and
- time-indicating indicia visible from the exterior of said shell, wherein said motion of said shell places one of said indicia in a predetermined position.
1 more element
A clock comprising:
- an ovoid shell having a longitudinal axis, an exterior surface and an interior surface defining an interior region;
- a post in said interior region attached to said interior surface and extending partially along said longitudinal axis;
- a rotating motor positioned in said interior region;
- a weight attached to said motor;
- means for rotatably attaching said motor and weight to said post, wherein the center of mass of said motor and attached weight are spaced form said longitudinal axis, and wherein rotation of said rotatable motor effects movement of said center of mass about said longitudinal axis to effect rolling motion of said shell when said shell is supported on a surface;
- a plurality of time-indicating indicia on said exterior surface, wherein said rolling motion of said shell positions one of said indicia in a vertically upward position to indicate time.
