Benefits of technology

0017] The invention provides the advantage that with only one drive, which already exists for the purpose of latching, the additional function of "safety locking" is achieved, whereby savings are achieved by avoiding additional production costs and additional door weight. There is no increase in inspection exp

Problems solved by technology

Dynamic loads on the door during the flight can result in vibrations which may cause a reversal of the latch action.

Embodiment Construction

[0024] The passenger door 20, 200 as such is a construction which is known from DE 197 02 084 C1 mentioned above. The passenger door is hingeable by a support arm on one side of the door frame DF of the aircraft fuselage F, so as to be liftable, swingable, and lowerable.

[0025] The following description refers to FIG. 1 and explains the latching and locking functions achieved according to the invention by a movement mechanism or drive D. FIG. 1 shows the device according to the invention in a "latched and safety locked position".

[0026] During a closing operation of a passenger door or a freight door, for the sake of brevity, herein referred to as "door", an operator swings the door from an open position along a swinging-in path. At the end of the swinging-in path, the door is positioned in front of a door opening formed by a door frame DF in the fuselage F. The operator in the interior of the passenger cabin operates the drive lever 10 of the drive D in the direction of the arrow A c...

Abstract

A door, especially an aircraft door, is first closed, for example manually. Then the door is first latched by a latching mechanism and locked by a locking mechanism. The latching mechanism and the locking mechanism are operatively connected through respective force transmitting couplings to a common drive in such a way that the latching mechanism is first moved to establish a latching position. Then, with a delay, the locking mechanism is moved into a locking position by the same drive to establish a latched and locked position.

Description

PRIORITY CLAIM[0001] This application is based on and claims the priority under 35 U.S.C. .sctn.119 of German Patent Application 100 20 825.8, filed on Apr. 28, 2000, the entire disclosure of which is incorporated herein by reference.[0002] The invention relates to a method and a device for closing a door, particularly of an aircraft. When a door is closed in a closed position, it is then also brought into a latched position, whereby the door is latched in the frame of the fuselage structure by a latch mechanism.BACKGROUND INFORMATION[0003] Conventional aircraft doors have at least one latch mechanism with a drive shaft drivable by a latch drive. The drive shaft is connected to a latch element arranged on a latch axis or shaft and to the latch drive. The latch element is adapted for engaging a latch stop arranged in the frame of the aircraft structure. German Patent Publication DE 197 02 084 C1 discloses such a door for an aircraft. The door is moved from an open position to a close...
