Toy vehicle having rolling oscillatory motion
First Claim
1. A toy vehicle comprising:
- a body;
a chassis at least having an upper surface; and
means provided on said upper surface of said chassis for permitting said body to exhibit a rolling oscillation motion around a horizontal axis, said means comprising;
a plate mounted on an internal surface of said body;
a plurality of connection rods for mechanically and movably connecting said plate to said upper surface of said chassis; and
at least a pushing up member mechanically connected to said chassis and having at least two contacting portions for contacting on a flat bottom surface of said plate at least at two symmetrical positions on opposite sides of a vertical plane containing said horizontal axis so as to permit either of said two contacting portions to push up said bottom surface of said plate wherein said two contacting portions alternatively and continuously push up said bottom surface of said movable plate to permit both said movable plate and said body to show a rolling oscillation motion around said horizontal axis, wherein said pushing up member comprises a V-shaped lever including a base portion pivotally connected to said chassis and two top pushing up portions spaced from each other on opposite sides of said plane.

Abstract
The invention provides a novel toy vehicle comprising a body, a chassis at least having an upper surface and a rolling oscillation generating unit provided on the upper surface of the chassis for permitting the body to exhibit a rolling oscillation motion around a horizontal axis. The rolling oscillation generating unit comprises a plate mounted to an internal surface of the body, a plurality of connection rods for mechanically and movably connecting the plate to the upper surface of the chassis, and at least a pushing up member mechanically connected to the chassis and having at least two contacting portions for contacting on a flat bottom surface of the plate at least at its two symmetrical positions spaced along a vertical direction to the horizontal axis so as to permit either of the two contacting portions to pushing up the bottom surface of the plate. The two contacting portions alternatively and continuously push up the bottom surface of the movable plate to permit both the movable plate and the body to show a rolling oscillation motion around the horizontal axis.

10. A radio controlled toy traveling vehicle comprising:
-
a body; a chassis at least having an upper surface; and means provided on said upper surface of said chassis for permitting said body to exhibit a rolling oscillation motion around a horizontal axis, said means comprising; at least two pairs of tires so mounted on shafts to said chassis as to permit said tires to freely rotate; at least an antenna for receiving radio wave signals from a transmitter and subsequently converting said radio wave signals into electrical signals; a driving motor mechanically connected through said shafts to said tires; a steering unit mechanically connected to at least one of said shafts mechanically connected to said tires; a control unit electrically connected to both said driving motor and said steering control unit for receiving said electrical signals and subsequently controlling said driving motor and further controlling said steering unit; a plate mounted on an internal surface of said body; a plurality of connection rods for mechanically and movable connecting said plate to said upper surface of said chassis; and at least a pushing up member mechanically connected to said chassis and having at least two contacting portions for contacting on a flat bottom surface of said plate at least at two symmetrical positions on opposite sides of a vertical plane containing said horizontal axis so as to permit either of said two contacting portions to push up said bottom surface of said plate wherein said two contacting portions alternatively and continuously push up said bottom surface of said movable plate to permit both said movable plate and said body to show a rolling oscillation motion around said horizontal axis. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
