Radio-controlled toy car with a rolling mechanism
First Claim
1. A mechanism for rolling a toy vehicle about the vehicle'"'"'s longitudinal axis, the mechanism comprising:
- a driving motor transmission for transmitting a motive force that propels the vehicle;
a rotation arm having a free end extending beyond a peripheral extent of the toy vehicle projected on a plane perpendicular to the vehicle'"'"'s longitudinal axis, and a pivotable fixed end around which said rotation arm rotates;
a shaft connected to said fixed end for rotating said rotation arm;
a flat gear movable along said shaft and for rotating said shaft;
a worm gear connected to said driving motor transmission for selectively driving said flat gear;
a spring member for impelling said flat gear along said shaft away from said worm gear;
a pivotable rod for selectively impelling said flat gear along said shaft towards said worm gear; and
means for moving said pivotable rod against a force from said spring member to selectively engage said flat gear with said worm gear, whereby the motive force from said driving motor transmission drives said rotation arm to roll the toy vehicle about the vehicle'"'"'s longitudinal axis.

Abstract
A rolling mechanism for a radio-controlled toy car causes a rolling motion of the radio-controlled toy car around a longitudinal direction along which the radio-controlled toy car travels. The rolling mechanism includes a rotation arm, which extends to have a component orthogonal to the longitudinal direction. The rotation arm has a free end and a pivotally fixed end, around which the rotation arm rotates, so that the free end defines a circle in a plane perpendicular to the longitudinal direction, where the circle completely encompasses the radio-controlled toy car in view of the perpendicular plane. A rotation mechanism is provided to be mechanically connected to the pivotally fixed end for forcibly rotating the rotation arm around the pivotally fixed end so as to roll the radio-controlled toy car around the longitudinal direction.

8. A mechanism for rolling a toy vehicle about the vehicle'"'"'s longitudinal axis, the mechanism comprising:
-
a rotation arm having a free end extending beyond a peripheral extent of the toy vehicle projected on a plane perpendicular to the vehicle'"'"'s longitudinal axis, and a pivotable fixed end around which said rotation arm rotates; a shaft connected to said fixed end for rotating said rotation arm; an auxiliary motor separate from means for propelling the vehicle, said auxiliary motor for generating a rotational force; and a rotational force transmission connecting said auxiliary motor to said shaft, whereby a force for rotating said rotation arm is independent of a force for propelling the vehicle.

9. A toy vehicle comprising:
-
a chassis having a longitudinal axis; a body on said chassis; a driving motor on said chassis for propelling the vehicle; a driving motor transmission for transmitting a motive force from said driving motor to vehicle motive means; a rotation arm having a free end extending beyond a peripheral extent of said body projected on a plane perpendicular to said chassis'"'"' longitudinal axis, and a pivotable fixed end around which said rotation arm rotates; a shaft connected to said fixed end for rotating said rotation arm; a flat gear movable along said shaft and for rotating said shaft; a worm gear connected to said driving motor transmission for selectively driving said flat gear; a spring member for impelling said flat gear along said shaft away from said worm gear; a pivotable rod for selectively impelling said flat gear along said shaft towards said worm gear; and means for moving said pivotable rod against a force from said spring member to selectively engage said flat gear with said worm gear, whereby the motive force from said driving motor transmission drives said rotation arm to roll the toy vehicle about said chassis'"'"' longitudinal axis. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
