Abstract

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.
