Abstract
Abstract A toy wherein remote objects are moved in response to the rotation of a steering wheel. A first embodiment has a pulley keyed to the shaft of the steering wheel, a second pulley journaled in the base of the toy and a belt therebetween. A drive arm arranged to snap into a slot on the side of a toy vehicle is affixed to the second pulley whereby its rotation will cause the drive arm and the vehicle to rotate. The drive arm includes a hinged center portion to permit vertical movement of its end in addition to the horizontal movement. In a second embodiment a ninety degree sector is secured at one apex to the steering wheel shaft, the sector being restrained to rotate only about ninety degrees before being returned to its original position. A rigid link has one end attached to a further apex of the sector and the other to a ratchet arm secured to a center post in the base of the toy. Also secured to the center post for rotation thereon is a ratchet wheel to which the drive arm is fixed. A pawl is secured to the ratchet arm and maintained by a spring in contact with the ratchet wheel. Rotation of the steering wheel in a back and forward direction will cause the link to move the ratchet arm in a forward and rearward direction to in turn rotate the drive arm in one direction.
