Abstract
An undulating display includes a rigid track, a pair of linking members secured to the track, a first pivot member having first pivot axis and a second pivot axis, and a second pivot member pivotally supported on the second pivot axis of the first pivot member. The pair of linking members is secured to the second pivot member. The display also includes an drive mechanism for pivoting simultaneously the second pivot member about the second pivot axis and the first pivot member about the first pivot axis thereby to produce undulating motion of the track.
Claims27
A display, comprising:
- a rigid, continuous, closed track;
- motion-transmitting means for imparting undulating motion to said rigid track, said motion-transmitting means including a compound pivot mechanism producing continuous, simultaneous pivoting motion about a fixed first axis and about a second axis different from said first axis;
- and
- connecting means for connecting said rigid track to said compound pivot mechanism to pivot about the second axis,
- wherein continuous simultaneous pivoting motion produced by said compound pivot mechanism about the first and second axes imparts undulating motion to said track.
A display, comprising:
- a rigid, continuous, closed track;
- undulation drive means, connected to said track, for moving said track in an undulating manner, said undulation drive means including a compound pivot mechanism producing simultaneous pivoting motion about first and second mutually perpendicular axes, said rigid track being connected to primarily pivot about the second axis and secondarily pivot about the first axis;
- and
- figuring means configured to roll on said track, said figurine means being driven around said track by the undulating motion thereof.
A display device, comprising:
- a rigid continuous, closed track;
- motion-transmitting means for imparting continuous undulating motion to said track, said motion-transmitting means comprising a compound pivot mechanism defining a first fixed axis, a first pivot member mounted to pivot reciprocally about the first axis and defining a second axis different from the first axis, a second pivot member mounted to pivot reciprocally about the second axis, and drive means for simultaneously driving said second pivot member to pivot continuously reciprocally about the second axis and said first pivot member to pivot continuously reciprocally about the first axis;
- and
- connecting means for connecting said track to said second pivot member;
- wherein simultaneous drive of said first and second pivot members by said drive means imparts continuous undulating motion to said track.
