A toy trap door mechanism is disclosed which includes a trap door pivotably mounted within and flush to a panel which simulates the floor of a castle. A chair in the shape of a throne is rotatably mounted to the floor in the vicinity of the trap door. An actuating lever is pivotably mounted to the underside of the floor and is operatively coupled to both the chair and the trap door. When the chair is rotated from a first position facing an observer to a second position facing the trap door, the lever unlatches the trap door which swings open. Holding the trap door in the closed position and rotating the chair to the first position resets the mechanism.

A motor operated walking doll which upon energization of the motor walks in a straight line for a given distance, then proceeds along a curve to turn around, then commences on a straight line to its approximate starting point whereupon the doll raises its arms, the arm raising action de-energizing the switch to the motor.

A captive flying toy airplane is tethered to a boom pivotally mounted to a turntable for pivoting the boom for altitude adjustment of a toy airplane, the turntable being mounted to a pylon base housing containing drive gears therein. A control housing is provided to position first and second wire control members passing through a tube connected to the housing, one controller of the control housing varying the position of a slide wire rheostat to control the speed of the toy airplane, the second controller pivoting a bell crank through a vertical plane to control the position of an altitude control rod passing through the center of the turntable to effect pivoting of the boom. A sound cone mounted within the pylon has the apex portion engaging a circumferential ratchet surface on one of the drive gears for emitting a simulated motor sound proportional to the speed of rotation of the gear.
