  • Metering toy for selecting a self-propelled vehicle of greatest strength
    Patent number: 4389810
    Abstract: A load-measuring device for a self-propelled toy truck vehicle, or the like, comprises a movable platform having a set of wheels and a friction sled mat movable on the surface upon which the vehicle is propelled. The strength of the vehicle is measured by the distance the platform is moved. The platform has a weighted body thereon movable up an inclined ramp towards the mat thereby to increase friction and load on the vehicle. A winch assembly on the wheels winds up a cable that pulls the body up the ramp progressively as the platform is moved by the vehicle to thereby stop movement as the vehicle strength is matched by the load. Thus, the strength of the vehicle is measured as a distance over which the platform is moved.
