.~ Object propelled along reciprocating or vibrating surface
DEFINITION
Classification: 463/65
Object propelled by reciprocating or vibrating surface:
(under subclass 58) Propelled racing wherein the mechanical force to place an object in motion includes a member having an exterior face (i.e., surface) and a means for imparting a back-and-forth or oscillatory motion to the surface whereby the object is caused to travel along the surface due to the surface motion when the object is engaged with the surface.
(1) Note. The shape of the surface is not limited to a
flat, roadlike surface, but may include such other shapes or forms such as a string or wire, etc.
(2) Note. Vibration used for a reason other than propelling an object toward a finish line, such as, for example, that used to overcome an object's inertia at rest to allow gravity propulsion thereafter, is not properly classified herein.
