The toy car system includes a chassis, a body, a finger engagement structure, a pair of front wheels rotatably coupled to the chassis, and a pair of rear wheels rotatably coupled to the chassis. Each of the front pair of wheels may be coupled to the front suspension by a castered coupling. The toy car may include a steering linkage between the front wheels configured such that the front wheels turn in unison in response to the motive force applied to the toy car.

DETAILED DESCRIPTION
(17) Described herein generally is a toy car configured to be driven by a user through engagement of a digit of the user and a finger receiving well positioned in the toy car. The configuration of the suspension and steering systems enable the user to steer the toy car simply by urging the car left and right, without the need for an actual steering wheel on the toy car.

(21) The toy car system 10 further includes a front suspension component 24A and a rear suspension component 24B, configured to respectively attach to an underside of the chassis 22. Additionally, the toy car system 10 includes a pair of front wheels 26A and 26B, and a pair of rear wheels 26C and 26D.

(25) The front and rear suspension components 24A and 24B are configured to include springs 46 to absorb and cushion vertical forces applied to the toy car such as a vertical component of the motive force applied to the car or vertical forces generated by motion of the toy car over a rough surface. In one specific example, the springs may be configured with a spring stiffness specific to the design of the toy car. For example, a track car design may have stiffer springs 46. Stiffer springs 46 provide more resistance and less cushioning of any vertical forces applied to the toy car as a track car is less likely to encounter rough play surfaces. An additional example would be the use of less stiff springs 46 for an off road car design as the off road car may be required to cushion vertical forces due to play on rough surfaces. It will be appreciated that springs 46 may be of any suitable stiffness depending on the play surfaces anticipated for a given toy car design. In one such embodiment, the travel of springs 46 may be configured to be 0.250 for all car models. Of course, it will be appreciated that variations on these travel figures are possible, and a first preferred range may vary 10% and a second preferred range may vary 20% from these precise figures.
(26) As shown in
(27) It will be noted that although the toy car is turnable and the wheels turn in unison due to the steering linkage, the chassis does not include a steering wheel configured to steer the front wheels. Rather, the turning of the car is effected by the actuation of a user's finger in a finger receiving well of a finger engagement structure coupled to the chassis. The actuation of the user's finger imparts a motive force to the toy car at the finger engagement structure. The motive force may include lateral, longitudinal, and/or vertical component forces. For the purposes of discussion, a lateral component force will be a force along the lateral axis of the toy car, a longitudinal force will be along the longitudinal axis of the toy car, and a vertical component force will be along the vertical axis of the toy car. The chassis, front and rear suspension components, front pair of wheels, the rear pair of wheels, and the steering linkage are configured to cooperatively translate the motive force to motion of the toy car in a horizontal plane as discussed in further detail below.

(32) As shown in
(33) The finger receiving well 34 may receive a force from a finger of a user having a vertical component, a horizontal component along the longitudinal axis of the toy car, and or a rotational component. The force is translated into motion of the toy car cooperatively by the finger receiving well, chassis, front and rear suspension, and steering linkage. For example, a user may provide a motive force whose component forces include a vertical component force downward and a longitudinal force forward at the finger receiving well. The motive force is transferred to the chassis which distributes the force to the front and rear suspension components. The vertical component may be absorbed in part or in whole by springs 46. The remaining horizontal component may then be translated to the wheels resulting in rotation of the wheels and a forward motion of the toy car. Another example may include a lateral component force to the motive force applied to the finger receiving well. In this case, the lateral component force is indicative of an intent to turn the car. In this instance, the castered front suspension and steering linkage translate the lateral component of the motive force into a steering force on the front wheels resulting in a non-zero steering angle (turning of a longitudinal centerline of the wheels away from a zero or neutral steering angle shown in
(34) In the alternative play mode where the force is applied at the body contour, the chassis, front and rear suspensions, and wheels function analogously to translate a multi-component motive force into motion of the toy car.
(35) It should be easily apparent from the above description that a user can readily assemble the various component parts of the toy car described herein. First and as shown if
(36) Although only two fasteners and fastener receiving holes 29 for securing the frame to the chassis are shown the Figures, additional fasteners and fastener receiving holes 29 may be included to secure the body components to the chassis. It will also be appreciated that alternative configurations of the fasteners and fastener receiving holes may be applied.
(37) As a further play option for users that purchase more than one of the toy cars in the product family, the user may interchange components between the street car, track car and dirt car to create custom toy cars having unique appearance and functionality, as desired. Thus, it is also contemplated that a toy car system is provided that includes a plurality of toy cars having interchangeable but differently shaped components having internally threaded regions positioned at standardized locations, the differently shaped components being connectable by externally threaded headed fasteners secured in the internally threaded regions.
(38) As discussed above, the functionally analogous components of the different toy car systems may be interchanged between the toy car systems providing the user with the capability of assembling hybrid toy cars. The wheels of any of the toy cars are attachable to the suspension of the other toy cars, and the suspension of any of the toy cars are attachable to the chassis of any of the other toy cars, and the body component of any of the toy cars are attachable to the chassis of any of the other toy cars, via the externally threaded headed fasteners. Furthermore, front suspension 24A and 24B are configured such that the front and rear suspensions may not be inadvertently switched. Further, front suspension 24A includes a slotted attachment hole 23A which allows fastener 28E to slide along the longitudinal axis of the front suspension and the chassis of the toy car to accommodate slight differences in the fastener receiving hole in the chassis of the various toy car systems. By interchanging these components, a myriad of possible configurations may be assembled by the user.
