Definitions
- the present invention relates to a toy vehicle.
- a toy vehicle comprising a chassis, a pair of non-steerable wheels and a pair of steerable wheels mounted on the chassis, a reversible motor mounted on the chassis and equipped with a first shaft.
- output associated with a transmission to drive the non-steered wheels in a forward movement regardless of the direction of rotation of the engine
- a second output shaft carrying a steering wheel steering control member, the steered wheels being mounted on supports articulated to the chassis around a substantially vertical axis and joined by a connecting bar.
- the control member comprises a friction sleeve mounted on the second engine output shaft and cooperating with a plate hingedly mounted on the vehicle chassis around a substantially vertical axis and connected hinged way to the link bar.
- the plate extends below the friction sleeve to be driven by the latter to the right or to the left depending on the direction of rotation of the motor.
- the ability of a device of this type to cause an orientation of the steered wheels is related to the degree of friction that the friction sleeve exerts on the steering control plate. This degree of friction is very difficult to adjust and acts directly on the general functioning of the vehicle.
- the steering control plate is suitably driven at each reversal of rotation of the engine but the engine is then braked at each change of direction, which causes a loss of speed of the vehicle. If on the contrary the degree of friction is insufficient, the vehicle is not braked but the change of direction of the steered wheels is not ensured in a suitable manner.
- the friction sleeve has been replaced by a drive pinion comprising a series of teeth and the steering wheel steering control plate has a lug which cooperates with the control pinion.
- the control lug does not remain parallel to the second output axis and it sometimes happens that the control lug escapes the teeth of the control pinion when reversing the direction of rotation of the motor so that the change of direction of the steered wheels is still not properly ensured.
- An object of the invention is to provide a vehicle comprising a control member ensuring a systematic change of direction of the steered wheels during a reversal of the direction of rotation of the engine while minimizing the slowing down of the engine during this change of direction .
- a toy vehicle comprising a chassis, a pair of non-steerable wheels and a pair of steerable wheels mounted on the chassis, a reversible motor mounted on the chassis and equipped with '' a first output shaft associated with a transmission to drive at least one of the non-steerable wheels in a forward movement regardless of the direction of rotation of the engine, and a second output shaft carrying a direction control member of steered wheels, the steered wheels being mounted on supports articulated to the chassis around substantially vertical axes and joined by a connecting bar, in which the control member comprises at least one control tooth carried by the second output shaft of the motor, and a steering control lug is carried by the link bar and extends opposite the second output shaft parallel to the latter.
- control tooth carried by the second motor output shaft makes contact over its entire length with the control lug carried by the link bar and it is assured of a positive engagement ensuring a change of direction of the steered wheels.
- control lug has a triangular section with an edge facing the second motor output shaft.
- the chassis has steering stops overhanging the connecting bar
- the connecting bar has projecting shoulders facing the steering stops.
- the toy vehicle comprises a chassis 1, a pair of non-steering wheels 2 mounted at the rear of the chassis and a pair of steering wheels 3 mounted at the front of the chassis.
- a reversible motor 4 is mounted on the middle part of the chassis and is powered by contacts not shown projecting from the underside of the chassis to rub on power lines carried by a circuit also not shown.
- the reversible motor 4 comprises a first output shaft 5 carrying a toothed pinion engaged in a manner known per se with transmissions 6 associated with the non-steerable wheels to drive the latter in a forward movement regardless of the direction motor rotation.
- the steering wheels 3 are carried by L-shaped supports 7 hinged to the chassis around substantially vertical axes 8.
- a branch 9 of each L-shaped support 7 extends towards the outside of the chassis and carries a steering wheel 3 while the other branch 10 of the L-shaped support extends substantially in a longitudinal direction of the vehicle towards the rear of this one.
- the branches 10 of the steering wheel supports are joined by a connecting bar 11 fixed in an articulated manner to the branches 10 of the steering wheel supports around articulation axes 12 substantially vertical.
- the connecting bar 11 carries a control lug 13 which extends rearwards opposite a second output shaft 14 of the reversible motor 4 parallel to the latter.
- the second output shaft 14 carries two steering control teeth 15 arranged symmetrically with respect to the output shaft 14 so that the weight of the control teeth 15 is balanced with respect to the output shaft 14 and does not not disturb the operation of the reversible motor 4 even when it rotates at very high speed.
- the control lug 13 is of course at a distance from the second output shaft 14 such that during the rotation of the motor 4, the teeth 15 bear on the control lug 13 and push the latter to the right or towards the left according to the direction of rotation of the motor 4.
- control pin 13 has a triangular section and has an edge 16 facing the second output shaft 14.
- the chassis has steering stops 17 overhanging the connecting bar 11 and the latter has shoulders 18 projecting opposite the steering stops 17.
- the connecting bar 11 is pushed back until one of the shoulders 18 comes into contact with one of the steering stops 17 so that the position of the connecting bar 11, and consequently, the orientation of the steered wheels 3 is determined with great precision.
- control pin 13 is arranged above the second output axis 14, it is possible to provide a control member 13 extending below the second output shaft 14.
- the arrangement of the control lug above the second second shaft is however preferred since it allows easier escape of the control lug 13 if the steered wheels 3 are blocked by a foreign body and this avoids wear excessive control teeth 15 or control lug 13.
- connecting bar 11 has been shown behind the pivot axes 8 of the steering wheel supports, this connecting bar can be arranged in front of these pivot axes.
- One can also provide a second output shaft equipped with more than two teeth, for example a toothed pinion with six teeth.
