Claims
- 1. A toy vehicle comprising a vehicle frame, a pair of drive wheels and at least one steering wheel mounted on said frame, said steering wheel being mounted for pivotal steering movement thereon; a reversible rotary drive motor mounted in said frame and having a rotary output; steering means operatively engaged with said rotary output of the motor for steering said drive wheel to the right or left depending upon the direction of rotation of said output including a steering arm operatively connected to said steering wheel to pivot the steering wheel in the right or left direction and steering transmission means operatively connected between said rotary output and said steering arm for converting rotation of said rotary output into left or right hand swinging movement of the arm in response to a change in the direction of rotation of said output; and drive transmission means in said frame drivingly engaged with said rotary output for driving said drive wheels in a forward direction regardless of the direction of rotation of said rotary output; said drive transmission means including at least one transmission element movably mounted in said frame for movement between first and second positions in response to the direction of rotation of the drive motor; said movably mounted transmission element including a gear support frame rotatably mounted for pivotal movement on an axis generally in alignment with the axis of rotation of said output and having at least one idler drive member rotatably mounted thereon and operatively engaged with said output, said idler drive member being associated with said drive wheels for respective operative engagement therewith in said first and second positions of the movably mounted transmission element to drive the vehicle in the forward direction regardless of the direction of rotation of the drive motor.
- 2. A toy vehicle as defined in claim 1 wherein said steering arm is pivotally mounted on said frame.
- 3. A toy vehicle as defined in claim 2 wherein said steering wheel includes a steering lever pivotally connected to said arm whereby pivotal movement of the arm is transmitted to said wheel.
- 4. A toy vehicle as defined in claim 3 wherein said steering transmission means includes a rotary power transmission element mounted on said motor output drivingly engaged with said arm to rotate the arm to the right or left in response to the direction of rotation of the motor output.
- 5. The toy vehicle as defined in claim 4 wherein said transmission element is a friction wheel frictionally engaged with said arm.
- 6. A toy vehicle comprising a vehicle frame, a pair of steering wheels pivotally mounted on said frame for simultaneous steering movement between right and left hand steering positions with respect to the frame; a pair of drive wheels rotatably mounted on the frame; a reversible rotary drive motor on said frame having a rotary output element; first transmission means drivingly engaged with said output element and said drive wheels for driving said drive wheels in the forward direction of travel of the vehicle regardless of the direction of rotation of said output element; a steering arm rotatably mounted on said frame for pivotal movement therein between first and second positions and operatively connected to said steering wheels for transmitting such pivotal movement thereto, and second transmission means operatively engaged between said motor output element and said arm for oscillating said arm between said first and second positions in response to a change in the direction of rotation of said motor output element, thereby to change the steering direction of said steering wheels; said first transmission means including at least one transmission element movably mounted in the frame for movement between first and second positions in response to the direction of rotation of the drive motor to respectively drivingly engage one or the other of said drive wheels; said movably mounted transmission element including a gear support frame rotatably mounted in said vehicle for rotation in a plane generally perpendicular to the plane of rotation of the drive wheels and having at least one idler gear rotatably mounted thereon and drivingly engaged with said output elements; said idler gear being located on said support frame for selective operative engagement with one or the other of said drive wheels in said first and second positions of the movably mounted transmission element.
- 7. A toy vehicle as defined in claim 6 wherein said second transmission means includes a rotary power transmission element mounted on said motor output drivingly engaged with said arm to rotate the arm to the right or left in response to the direction of rotation of the motor output.
- 8. The toy vehicle as defined in claim 7 wherein said transmission element is a friction wheel frictionally engaged with said arm.
