Four wheel drive toy locomotive
First Claim
1. A self-powered toy vehicle which is attachable to a second toy vehicle and capable of transferring movement to the second toy vehicle, the self-powered toy vehicle comprising:
- a housing having an interior surface and an exterior surface;
a first wheel system and a second wheel system each having a pair of wheels, at least a portion of each wheel extending beyond the exterior surface of the housing;
a motor engaging a gear assembly for providing energy to the first wheel system; and
a selectively activated clutch assembly interconnected to the gear assembly for disengaging the gear assembly from the first wheel system in response to a damaging external force provided to the self-powered toy vehicle wherein the first wheel system can be separately temporarily released from the gear assembly in response to the damaging external force; and
a transmission switch interconnected to the selectively activated clutch assembly providing a spring force to engage and disengage the gear assembly.

Abstract
A battery operated miniature toy locomotive for use in a toy railway system is claimed. The toy railway system comprises a toy railway track configuration made up of a plurality of wooden toy railway track segments. Each wooden track segment has a pair of uniformly spaced depressions extending from a first connecting end to a second connecting end of each wooden track segment. The toy locomotive has a first pair of wheels positioned at a proximal end of the toy locomotive and a second pair of wheels positioned at a distal end of the toy locomotive. The first and second pairs of wheels are adapted for placement within the depressions formed on each wooden track segment. The toy locomotive further comprises a locomotive housing which has an interior surface and an exterior surface, and a motor for providing energy to the first pair of wheels and the second pair of wheels. The motor is positioned within the housing and operatively connected with the first pair of wheels and the second pair of wheels wherein both pairs of wheels are simultaneously powered by the motor.

8. A toy railway system comprising a miniature battery operated toy locomotive attachable to a second toy railway vehicle for traversing along a toy railway track configuration made up of a plurality of wooden toy railway track segments, each wooden track segment having a pair of uniformly spaced depressions extending from a first connecting end to a second connecting end of each wooden track segment, the toy locomotive having a first pair of wheels positioned at a proximal end of the toy locomotive and a second pair of wheels positioned at a distal end of the toy locomotive, the first and second pairs of wheels adapted for placement within the depressions formed on each wooden track segment, the toy locomotive comprising:
-
a toy locomotive housing having an interior surface and an exterior surface; a motor for providing energy to the first pair of wheels and the second pair of wheels, the motor positioned within the housing and operatively connected to a first gear assembly which is operatively connected to the first pair of wheels and a second gear assembly which is operatively connected to the second pair of wheels wherein both pairs of wheels are simultaneously powered by the motor; a first selectively activated clutch assembly and a second selectively activated clutch assembly interconnected to the first and second gear assemblies respectively for separately disengaging the first and second gear assemblies from the first and second pairs of wheels in response to a damaging external force provided to the toy locomotive wherein the first and second pairs of wheels can be separately temporarily released from the first and second gear assemblies respectively in response to the damaging external force; and a transmission switch interconnected to the first and second selectively activated clutch assemblies providing a spring force to engage and disengage the first and second gear assemblies.

9. A self-powered toy vehicle attachable to a second toy vehicle and capable of transferring movement to the second toy vehicle, the self-powered toy vehicle comprising:
-
a housing having an interior surface and an exterior surface; a first wheel system having a pair of wheels, at least a portion of each wheel extending beyond the exterior surface of the housing; a motor for providing energy to the first wheel system positioned within the housing; and a first wobble gear assembly engaging the motor at a first end and the first wheel system at a second end for transferring energy from the motor to the first wheel system wherein the wobble gear assembly comprises; a pinion connected to a drive shaft which extends from the motor; a crown gear for engaging the pinion on one side and having an eccentric spur gear driver on an opposing side; a spur gear in communication with the eccentric spur gear driver wherein a rotational movement provided to the crow gear produces an orbital movement in the spur gear; an internal gear powered by the spur gear wherein the orbital movement of the spur gear produces a rotational movement in the internal gear; and a rod connected at a first end to the internal gear and having a second end for transferring energy to the first wheel system wherein the rotational movement by the internal gear is transferred along the rod to the first wheel system. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A self-powered vehicle which is attachable to a second toy vehicle and capable of transferring movement to the second toy vehicle, the self-powered toy vehicle comprising:
-
a housing having an interior surface and an exterior surface; a first wheel system having a pair of wheels, at least a portion of each wheel extending beyond the exterior surface of the housing; a motor for providing energy to the first wheel system positioned within the housing; and a pinion connected to a drive shaft which extends from the motor; a crown gear for engaging the pinion on one side and having an eccentric spur gear driver on an opposing side; a spur gear in communication with the eccentric spur gear driver wherein a rotational movement provided to the crown gear produces an orbital movement in the spur gear; an internal gear powered by the spur gear wherein the orbital movement of the spur gear produces a rotational movement in the internal gear; and a rod connected at a first end to the internal gear and having a second end for transferring energy to the first wheel system wherein the rotational movement by the internal gear is transferred along the rod to the first wheel system.
