Abstract

Abstract A toy vehicle resembling a dune buggy and designed to give the appearance of movement over rough terrain when the vehicle is either motor driven or free wheeled along the ground. The vehicle has an open passenger compartment containing a pair of seat that can receive dolls, a mechanism coupled to the rear axle that simultaneously pivots both seats from one side to the other as the vehicle rolls along the ground so that the vehicle appears to be tilting from side to side in the opposite direction. A gearshift lever in the passenger compartment can be operated to slide a switch member. When the switch member is slid to one side, it turns off an electric motor and also slides a worm gear out of engagement with a screw on the motor shaft, so that the vehicle is free wheeling when the motor is turned off.

A toy vehicle comprising: a toy vehicle frame; an electrically energizable motor mounted on said frame; current source means for supplying current to said motor; a transmission member coupled to said motor to be rotated by it; an axle rotatably mounted on said frame, said axle having spline means thereon; a wheel fixed to said axle to rollably support it and to be driven by it; a gear slideably mounted on said axle and slideably engaged with said spline means thereon; contact means for closing and opening to energize and deenergize said motor, respectively; and switch means including a switch member movable to a first position to close said contact means and slide said gear along said axle into engagement with said transmission member, and movable to a second position to open said contact means and slide said gear out of engagement with said transmission member, whereby to permit free wheeling of the vehicle when the motor is not energized.
Claim 2
Dependent Claim 160 words
A toy vehicle comprising: a toy vehicle frame; an electrically energizable motor mounted on said frame; current source means for supplying current to said motor; a transmission member coupled to said motor to be rotated by it; an axle rotatably mounted on said frame, said axle having spline means thereon; a wheel fixed to said axle to rollably support it and to be driven by it; a gear slideably mounted on said axle and slideably engaged with said spline means thereon; contact means for closing and opening to energize and deenergize said motor, respectively; and switch means including a switch member movable to a first position to close said contact means and slide said gear along said axle into engagement with said transmission member, and movable to a second position to open said contact means and slide said gear out of engagement with said transmission member, whereby to permit free wheeling of the vehicle when the motor is not energized.
Claim 3
Dependent Claim 68 words
The toy vehicle described in claim 1 wherein: said current source means includes a battery holder; said contact means includes a contact electrically coupled to said motor and mounted for deflection towards and away from the terminal of a battery within said battery holder; and said switch member is engaged with said contact to deflect and release it so it moves away from and against said battery terminal.
Claim 4
Dependent Claim 70 words
The toy vehicle described in claim 1 wherein: said frame defines an open passenger compartment; and including an on-off lever pivotally mounted on said frame about an axis extending substantially along the length of the vehicle, and having a forward end resembling a gearshift lever and extending into said front passenger compartment and a rear end engaged with said switch member to shift it between said first and second positions.
Claim 5
Dependent Claim 142 words
A toy vehicle comprising: a toy vehicle frame; an axle rotatably mounted on said frame; a wheel fixed to said axle; a motor mounted on said frame; a screw coupled to said motor to be rotated by it; a worm wheel slideably mounted on said axle, to slide between a position in engagement with said screw and a position out of engagement with it, said axle and worm wheel having engaging means rotatably coupling them at least when said worm wheel is in said position wherein it engages said screw; a seat; means for coupling said seat to said axle to move said seat relative to said frame; and manually operable means for sliding said worm wheel on said axle, whereby said seat moves when the vehicle rolls on the ground regardless of whether the vehicle is motor driven or free wheeling.
Claim 6
Dependent Claim 142 words
A toy vehicle comprising: a toy vehicle frame; an axle rotatably mounted on said frame; a wheel fixed to said axle; a motor mounted on said frame; a screw coupled to said motor to be rotated by it; a worm wheel slideably mounted on said axle, to slide between a position in engagement with said screw and a position out of engagement with it, said axle and worm wheel having engaging means rotatably coupling them at least when said worm wheel is in said position wherein it engages said screw; a seat; means for coupling said seat to said axle to move said seat relative to said frame; and manually operable means for sliding said worm wheel on said axle, whereby said seat moves when the vehicle rolls on the ground regardless of whether the vehicle is motor driven or free wheeling.
Claim 7
Dependent Claim 38 words
The toy vehicle described in claim 4 wherein: said manually operable means is coupled to said motor to turn it on and off as said worm wheel is respectively slid into and out of engagement with said screw.
Claim 8
Dependent Claim 172 words
A toy vehicle comprising: a toy vehicle frame having forward and rearward end portions; a motor mounted on said frame and having a transmission member coupled to its motor shaft; an axle rotatably mounted on said rearward end portion of said frame, said axle having spline means thereon; a wheel fixed to said axle; a gear mounted on said axle and slideably engaged with said spline means; a switching member slideably mounted on said rearward end portion of said frame to slide substantially laterally thereon between first and second positions, said switching member having a pair of arm portions at opposite faces of said gear, to slide said gear between a first position wherein it is engaged with said transmission member and a second position wherein it is disengaged from it, when said switching member is respectively slid between its first and second positions; and means coupling said switching member to said motor to turn it on and off when said switching member is slid to its first and second positions, respectively.
Claim 9
Dependent Claim 172 words
A toy vehicle comprising: a toy vehicle frame having forward and rearward end portions; a motor mounted on said frame and having a transmission member coupled to its motor shaft; an axle rotatably mounted on said rearward end portion of said frame, said axle having spline means thereon; a wheel fixed to said axle; a gear mounted on said axle and slideably engaged with said spline means; a switching member slideably mounted on said rearward end portion of said frame to slide substantially laterally thereon between first and second positions, said switching member having a pair of arm portions at opposite faces of said gear, to slide said gear between a first position wherein it is engaged with said transmission member and a second position wherein it is disengaged from it, when said switching member is respectively slid between its first and second positions; and means coupling said switching member to said motor to turn it on and off when said switching member is slid to its first and second positions, respectively.
Claim 10
