Abstract

Abstract A toy vehicle having an electric motor which is connected to one of its wheels by an interruptible drive linkage, the engagement of which is controlled by a switch for the motor. The switch member preferably has three positions for ''''on,'''' ''''off'''' and reverse and is arranged to bear against a pivotable motor mounting and to disengage a drive transmitting shaft from the wheel, when moved to the ''''off'''' position, so that the vehicle can ''''free-wheel''''.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 120 words
A toy vehicle drivable from a source of power comprising: a body; at least three wheels rotatably mounted on said body; a motor; an on/off reversing switch selectively interconnecting and disconnecting said motor and said source of power; an interruptible driven linkage between said motor and at least one of said wheels to the switch for the motor, the arrangement being such that movement of the switch to the ''''off'''' position acts to interrupt the drive; and cam means integral with and responsive to said reversing switch only while said reversing switch is interconnecting said motor and said source of power for actuating said linkage to couple said linkage and said at least one of said wheels in driving relation.
Claim 2
Dependent Claim 120 words
A toy vehicle drivable from a source of power comprising: a body; at least three wheels rotatably mounted on said body; a motor; an on/off reversing switch selectively interconnecting and disconnecting said motor and said source of power; an interruptible driven linkage between said motor and at least one of said wheels to the switch for the motor, the arrangement being such that movement of the switch to the ''''off'''' position acts to interrupt the drive; and cam means integral with and responsive to said reversing switch only while said reversing switch is interconnecting said motor and said source of power for actuating said linkage to couple said linkage and said at least one of said wheels in driving relation.
Claim 3
Dependent Claim 63 words
A toy vehicle according to claim 1 further comprising: a pivotable mounting for the motor; said motor having a driveshaft; said linkage including a frictional drive transmitting member on said motor shaft and engagable with said at least one of said wheels; and said cam means including biassing means for said pivotable mounting normally urging said transmitting member into engagement with said wheel.
Claim 4
Dependent Claim 147 words
A battery powered toy vehicle comprising: a body; at least three wheels rotatably mounted on the body; a motor; a driveshaft on said motor; a switch for selectively connecting and disconnecting said battery and said motor; a pivotable mounting for said motor; a frictional drive transmitting member on said driveshaft and engagable with one of said wheels; biassing means for said pivotable mounting normally urging said drive transmitting member into engagement with said wheel; a pivotably-mounted switch member coupled with said switch and movable therewith, one end of said switch member abutting against the mounting of the motor in camming relation; said switch having an ''''on'''' and an ''''off'''' position; the relative arrangements of said switch member and said pivotable mounting being such that on movement of said switch member to said drive transmitting member of said motor shaft is cammed out of engagement with said wheel.
Claim 5
Dependent Claim 147 words
A battery powered toy vehicle comprising: a body; at least three wheels rotatably mounted on the body; a motor; a driveshaft on said motor; a switch for selectively connecting and disconnecting said battery and said motor; a pivotable mounting for said motor; a frictional drive transmitting member on said driveshaft and engagable with one of said wheels; biassing means for said pivotable mounting normally urging said drive transmitting member into engagement with said wheel; a pivotably-mounted switch member coupled with said switch and movable therewith, one end of said switch member abutting against the mounting of the motor in camming relation; said switch having an ''''on'''' and an ''''off'''' position; the relative arrangements of said switch member and said pivotable mounting being such that on movement of said switch member to said drive transmitting member of said motor shaft is cammed out of engagement with said wheel.
Claim 6
Dependent Claim 154 words
A toy vehicle comprising: a body; at least three wheels rotatably mounted on said body; a reversible electric motor; a source of electric current for said motor; a switch having on, off and reverse positions controlling the supply of current to said motor; a driveshaft on said motor; a pivotable mounting for said motor; a frictional drive transmiting member on said driveshaft and engagable with one of said wheels; biassing means for said pivotable mounting normally urging said drive transmitting member into engagement with one of said wheels; and a pivotably-mounted switch member coupled to said switch and movable therewith, said switch member having one end abutting against said pivotable mounting in connection relation; said member being so located and arranged with respect to said pivotable mounting that only on movement of said switch member to said off position is said drive transmitting member urged out of engagement with said one of said wheels.
Claim 7
Dependent Claim 154 words
A toy vehicle comprising: a body; at least three wheels rotatably mounted on said body; a reversible electric motor; a source of electric current for said motor; a switch having on, off and reverse positions controlling the supply of current to said motor; a driveshaft on said motor; a pivotable mounting for said motor; a frictional drive transmiting member on said driveshaft and engagable with one of said wheels; biassing means for said pivotable mounting normally urging said drive transmitting member into engagement with one of said wheels; and a pivotably-mounted switch member coupled to said switch and movable therewith, said switch member having one end abutting against said pivotable mounting in connection relation; said member being so located and arranged with respect to said pivotable mounting that only on movement of said switch member to said off position is said drive transmitting member urged out of engagement with said one of said wheels.
