    Patent number: 11185789
    Abstract: Described herein is a method for producing a toy, in particular a toy car. According to a preferred embodiment, said method envisages implementing a process of injection moulding that envisages a first step of forming the base body (40) of the toy car, and, then, a second step of forming the wheels (60), which is carried out directly on the base body formed previously. The toy car obtained is characterized in that it presents a connection that cannot be separated between the wheels and the base body.

    Abstract: The present invention relates to a suspension system for a toy vehicle. The suspension system is independent in that it comprises at least four damping mechanisms (shock absorber), each shock absorber being located proximal to each wheel location. Each shock absorber utilizes a tensioning device, such as a compressed spring, positioned between the toy vehicle chassis and a suspension arm, to provide the active damping feature of the invention. Each shock absorber also utilizes an adjustment means, such as a screw, to selectively change the distance between the suspension arm and chassis. As the screw is adjusted, so the spring is either more or less compressed, providing for a stiffer (more compressed) or a softer (less compressed) suspension.

In another embodiment, the wheels on each lateral side are drivingly coupled with a single reversible motor. The vehicle is steered through one-way clutches which allow the wheels on one lateral side to operate in either a forward or a reverse direction while the wheels on an opposite lateral side always rotate in the same direction. In both embodiments, a pivoting beam is centrally located on one lateral side, with the wheels on that side being rotatably attached to the beam. The pivoting beam provides for infinite ranges of suspension positions. In operation, the vehicle proceeds until it encounters an obstacle.

  • Patent number: 6589051
    Abstract: A mechanism includes a first member having a channel and a second member with a generally cylindrical portion at least partially received in the channel. The second member includes a stop portion for limiting relative movement of the first member and the second member. The stop portion is made of a formable material and includes at least three lobes that extend outwardly in different respective directions. The stop portion increases the stiffness of the second member, and is useful in both pivoting and rotating mechanisms for limiting relative movement between the first member and the second member.

  • Patent number: 6475059
    Abstract: A radio controlled toy vehicle having a single driving wheel. First and second chassis bodies are located on opposite sides of the driving wheel, and the driving wheel and chassis bodies rotatably attached to a primary axle. Support wheels are rotatably attached to the chassis bodies at a location distal to the point of attachment of the chassis bodies to the primary axle. First and second reversible electric motors are drivingly connected to the driving wheel by drive train means. A radio control receiver is attached to one of the chassis bodies, and is adapted to independently actuate the electric motors in a forward or reverse direction in response to control signals sent by a radio control transmitter. When both of the electric motors are operating in the forward or reverse direction, the driving wheel propels the vehicle in that direction.

  • Patent number: 6419547
    Abstract: An undercarriage for a vehicle such as a toy truck or an adult size riding vehicle where the undercarriage allows a vertically directed tilt force to engender a turning movement of the wheels. The undercarriage is simply constructed of two spaced apart brackets having oblique slots through which an axle running between the wheels pass. The axle is also engaged by a fulcrum located midway between the brackets and two biasing tabs which are located between the fulcrum and each of the brackets. In straight ahead movement, the axle is slightly biased by the tabs to be located about the mid-point of the slots. However, when a tilt force is applied to the vehicle, then the axle will move to a lower portion of one of the slots and the upper portion of the other slot. At the same time one of the tabs is flexed so as to increase its biasing force on the axle. When the tilt force is removed, the biasing force of the tab pushes the axle to its mid-point position in the slots.
