An apparatus includes a pair of frame members adapted for mounting to opposing surfaces of a passageway. A door is mounted to at least one of the frame members for movement between a closed position, in which the door and frame members substantially traverse the passageway, and an open position, in which a portion of the passageway is free of the door and frame members, the portion being large enough to permit passage of an adult therethrough. A lock is coupled to at least one of the frame members and adapted to retain the door in the closed position, the lock including an actuator adapted to release the lock to permit movement of the door from the closed position toward the open position upon application to the actuator of a force of at least a predetermined weight of a child.
