Abstract: Controllable response systems for providing remote control over one or more toy objects, such as a miniature toy vehicle, on a playing surface. A linkage mechanism beneath the playing surface has an end which is accessible to an operator and is used to manipulate another end, beneath the surface, which is magnetically coupled to the object being controlled. The linkage mechanism is adjustable to control the relationship between the area of movement of the end accessible to an operator and the area of the playing surface over which the toy object is moved.

Abstract: Hoppity toy systems formed by the combination of a hoppity toy with a variety of mechanical devices, such as an elevator and other moveable objects. The hoppity toy is directed by a track which confines the hopping motion to a prescribed route that includes a hoppity toy operable device.

Abstract: A toy vehicle which includes a mechanism for firing projectiles such as rockets. After the vehicle has been operative for a prescribed period of time the rocket is fired. Simultaneously, or after a coordinated delay, the vehicle is caused to undergo a change in operation, such as a change in speed such that the impression is given that the speed change is caused by the firing of the rocket.

Abstract: Controllable response toy systems in which the response is delayed by a suitable interval. A toy is set for action by the manipulation of one of its members, such as an arm. The arm thereafter moves spontaneously from the set position, after a suitable interval, and brings about a desired action, such as the throwing of a ball. When the interval resulting from the setting action is variable, the toy gives the appearance of deciding on its own when to take action.
