Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
131 words
A toy vehicle comprising a wheeled chassis, an electric motor and battery for driving at least one wheel, via gearing means driven by said motor for steering a pair of wheels on a common axis transversely of the chassis, said steering means comprising a vertical spindle rotatable through gearing by the motor and extending into a well accessible from the underside of the chassis, a steering control disc axially engageable on said spindle in said well, manually releasable means for holding said disc in said well, a contoured control groove in a surface of said disc, and a rocker arm coupled at one end into the groove and at its other end to the said pair of wheels to effect steering of said wheels in accordance with the contoured control groove.
Claim 2
Dependent Claim
131 words
A toy vehicle comprising a wheeled chassis, an electric motor and battery for driving at least one wheel, via gearing means driven by said motor for steering a pair of wheels on a common axis transversely of the chassis, said steering means comprising a vertical spindle rotatable through gearing by the motor and extending into a well accessible from the underside of the chassis, a steering control disc axially engageable on said spindle in said well, manually releasable means for holding said disc in said well, a contoured control groove in a surface of said disc, and a rocker arm coupled at one end into the groove and at its other end to the said pair of wheels to effect steering of said wheels in accordance with the contoured control groove.
Claim 3
Dependent Claim
39 words
A toy vehicle as claimed in claim 1, comprising a drive disc carrying said spindle, a ratchet tooth periphery on said drive disc and a pawl reciprocated by said motor engaging said tooth periphery to rotate the drive disc.
Claim 4
Dependent Claim
24 words
A toy vehicle as claimed in claim 1 comprising a plurality of control discs any one of which is selectively engageable on said spindle.
Claim 5
Dependent Claim
41 words
A toy vehicle as claimed in claim 1, comprising on-off switch contacts mounted on said chassis adjacent the control disc and connected in the electric circuit to the motor, and means on said control disc for opening or closing said contacts.
Claim 6
Dependent Claim
24 words
A toy vehicle as claimed in claim 4 wherein the control disc has a notch in its periphery adapted to co-operate with said contacts.
Claim 7
Dependent Claim
161 words
A toy vehicle comprising a chassis including a platform with two parallel spaced longitudinal ribs, a pair of front wheels and a pair of rear wheels carried by said chassis, a battery carrying cradle on the outside of each rib, an electric motor in a compartment at the rear of said chassis, drive gearing between said motor and a rear wheel shaft, an eccentric on said shaft, a bar extending forwardly from said eccentric to be reciprocated by said eccentric, a drive disc carrying an axial and vertical spindle substantially at the center of said chassis, ratchet teeth on the periphery of said drive disc engaged by the front end of said bar, a control disc releasably mounted in a well below and co-axial with said drive disc, a contoured steering control groove in a surface of said disc, and a mechanical coupling between said groove and the front wheels to steer said front wheels in accordance with the groove contour.
Claim 8
Dependent Claim
161 words
A toy vehicle comprising a chassis including a platform with two parallel spaced longitudinal ribs, a pair of front wheels and a pair of rear wheels carried by said chassis, a battery carrying cradle on the outside of each rib, an electric motor in a compartment at the rear of said chassis, drive gearing between said motor and a rear wheel shaft, an eccentric on said shaft, a bar extending forwardly from said eccentric to be reciprocated by said eccentric, a drive disc carrying an axial and vertical spindle substantially at the center of said chassis, ratchet teeth on the periphery of said drive disc engaged by the front end of said bar, a control disc releasably mounted in a well below and co-axial with said drive disc, a contoured steering control groove in a surface of said disc, and a mechanical coupling between said groove and the front wheels to steer said front wheels in accordance with the groove contour.
