Description

Die Erfindung betrifft eine Verriegelungsvorrichtung für Schiebetüren von Luftfahrzeugen, insbesondere von Hubschraubern gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a locking device for sliding doors of aircraft, in particular of helicopters according to the preamble of claim 1.

Solche für den Zustieg des Piloten oder für den Zustieg von Passagieren dienende Schiebetüren werden, ähnlich wie bei Landfahrzeugen, über seitliche Führungsschienen im Abstand seitlich längs der Außenfläche der Rumpfstruktur bis in die Höhe der Türöffnung geführt und dann über geeignet abgebogene Enden der Führungsschienen in die Türöffnung gezogen. Hierzu ist die Schiebetür von Hand zu bewegen und zudem in der Schließstellung von Hand zu verriegeln. Anders als bei Landfahrzeugen müssen bei Luftfahrzeugen die dort innerhalb der in der Rumpfstruktur vorgesehenen Öffnungen vorhandenen Türen absolut sicher eingestrakt und verschlossen sein. Das Verschließen solcher Schiebetüren erfordert daher drei aufeinanderfolgende manuelle Handhabungen, nämlich Zuziehen der Tür, Halten der Tür in diesen Zustand und anschließend deren Verriegeln. Hierzu sind mit der Türstruktur mindestens zwei Türschlösser verbunden, deren mit an der Rumpfstruktur befestigten Beschlägen zusammenwirkende Zuhaltungen über ein geeignetes einen Handgriff aufweisendes Gestänge gemeinsam betätigbar sind. Es ist also beim Schließen solcher Türen für die zwei letzten Handhabungen besonderes Geschick nötig, da die jeweilige Tür beim Verriegeln in der Schließlage fest zu halten ist. Ist die Tür nicht ausreichend genug zugeschoben, kann es passieren, dass die eine oder andere Zuhaltung "in's Leere" greift und daher die betroffene Tür nicht ordnungsgemäß verschlossen ist. Für das Schließen der Tür werden daher in der Regel beide Hände der betroffenen Person benötigt.Such serving for the approach of the pilot or for boarding passengers sliding doors are, similar to land vehicles, laterally guided laterally along the outer surface of the fuselage structure over lateral guide rails to the height of the door opening and then suitably bent ends of the guide rails in the door opening drawn. For this purpose, the sliding door is to be moved by hand and also to lock in the closed position by hand. In contrast to land vehicles, in the case of aircraft, the doors provided there within the openings provided in the fuselage structure must be securely entrenched and closed. The closure of such sliding doors therefore requires three consecutive manual operations, namely closing the door, holding the door in this state and then locking it. For this purpose, at least two door locks are connected to the door structure, the tumblers cooperating with fastened to the hull structure fittings can be actuated together via a suitable handle having a linkage. It is therefore necessary when closing such doors for the last two operations special skill, since the respective door is to hold firmly when locking in the closed position. If the door has not been pushed closed enough, it can happen that one or the other lock is "in the void" and therefore the affected door is not properly closed. As a rule, both hands of the person concerned are therefore required for closing the door.

Die bisher bekannten Türschlösser für solche Schiebetüren sind offensichtlich bedienerunfreundlich. Zwar hat man für das Türöffnen, solange man vor dem Hubschrauber steht, genügend Platz und Bewegungsfreiheit für das Öffnen und Schließen der Tür und kann ein Ziehen, Halten, Drücken und/oder Drehen ohne größere Schwierigkeiten ausführen. Dies ändert sich jedoch sofort nach dem Einsteigen und Platznehmen im Hubschrauber; bedingt durch die eingeschränkte Ergonomie und der Tatsache, dass z. B. Piloten- oder Passagiersitze abhängig von Körpergröße nach vorne und nach oben verstellbar ausgebildet sind, ist dann das Bedienen solcher Türen um ein Vielfaches erschwert.The previously known door locks for such sliding doors are obviously user-friendly. Although you have to open the door while standing in front of the helicopter, enough space and freedom of movement for the opening and closing of the door and can perform a drag, hold, press and / or rotate without much difficulty. However, this changes immediately after boarding and seating in the helicopter; due to the limited ergonomics and the fact that z. B. pilot or passenger seats are designed depending on body size forward and upward adjustable, then the operation of such doors is made much more difficult.

Die Türen eines Hubschraubers stellen den ersten Kontakt zum Fluggerät her und bestimmen somit den ersten Eindruck an den jeweiligen Benutzer. Es besteht daher Forderung, dass Türen von ihrer Bedienbarkeit und Funktion selbsterklärend ausgebildet sind und nicht schon das erste manuelle und/oder technische Hindernis beim Einstieg in den Hubschrauber bilden. Die Funktionen der Türverriegelung sollten ebenfalls ohne zusätzliche Beschilderungen und Hinweise für jedermann verständlich und logisch bedienbar sein.The doors of a helicopter make the first contact with the aircraft and thus determine the first impression to the respective user. There is therefore a requirement that doors are self-explanatory of their operability and function and do not already constitute the first manual and / or technical obstacle when entering the helicopter. The functions of the door lock should also be understandable and logical without additional signs and instructions for everyone.

Ein gattungsgemäßes Türverriegelungssystem für eine Hubschraubertür mit einem translatorisch beweglichen Verriegelungssystem ist aus der DE 3 707 324 A1 bekannt. Als nachteilig erweist sich hierbei, dass die Hubschraubertür beim Verriegeln in der Schließlage festzuhalten ist, sodass zum Verschließen der Tür beide Hände benötigt werden.A generic door locking system for a helicopter door with a translationally movable locking system is from the DE 3 707 324 A1 known. A disadvantage here proves to be that the helicopter door is locked when locking in the closed position, so that both hands are required to close the door.

Aus der eine Türschließvorrichtung für Kraftwagen betreffenden DE 9 311 255 U1 ist eine sogenannte Schlagtür bekannt, die bei einer Schließbewegung und vor Erreichen der endgültigen Schließlage eine Vorraststellung einnimmt.From a door closing device for motor vehicles concerned DE 9 311 255 U1 a so-called flap door is known, which assumes a pre-locked position during a closing movement and before reaching the final closed position.

Der Erfindung liegt daher die Aufgabe zugrunde, eine neue Türverriegelungsvorrichtung zu schaffen, die unter Beibehalten der Schließsicherheit besser als bisher bedienbar ist.The invention is therefore an object of the invention to provide a new door lock device that is better than previously operated while maintaining the security lock.

Ausgehend von einer mittels Schienen geführten translatorisch betätigbaren Schiebetür mit mindestens einer eine Raste hintergreifenden, als Zahnstange ausgebildeten Schlossfalle ist diese Aufgabe gemäß der Erfindung durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst.Starting from a run guided by rails translationally operable sliding door with at least one detent engaging behind, designed as a rack lock latch, this object is achieved according to the invention by the characterizing features of claim 1.

Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen.Further features of the invention will become apparent from the dependent claims.

Die neue Türverriegelung ist überraschend vorteilhaft.
Mit Hilfe der erfindungsgemäßen Fangfalle, die mit der Schlossfalle in getrieblicher Wirkverbindung steht, wird nämlich vor dem Wirksamwerden der Schlossfalle die betroffene, als Schiebetür ausgebildete Tür in der Lage, in der die Schlossfalle erst im Bereich der Raste ist, "gefangen", sodass allein durch weiteres Bewegen der Schlossfalle in deren Schießlage die Tür in ihre endgültige Schließlage überführbar ist, ohne das hierzu ein Halten/AnzieheNAndrücken der Tür in die in der Rumpfstruktur vorhandene Öffnung von Hand notwendig ist. Bei der Überführung der Schlossfalle in ihre endgültige Schließstellung mittels des genannten Handgriffs wird über die getriebliche Verbindung zwischen Fang- und Schlossfalle, die erfindungsgemäß als Schiebekeil ausgebildet ist, die Fangfalle für einen neuen Schließvorgang wieder freigegeben.The new door lock is surprisingly advantageous.
With the help of the catch catch according to the invention, which is in geared engagement with the latch, namely the affected, designed as a sliding door door in the position in which the latch is only in the catch, "caught", so alone by further moving the latch in the firing position, the door can be moved to its final closed position, without the need for holding / tightening the door in the manual opening provided in the fuselage structure. In the transfer of the latch in its final closed position by means of said handle is released via the geared connection between catch and latch, which is inventively designed as a sliding wedge, the catch for a new closing operation.

Die erfindungsgemäße Ausbildung der Türverriegelung erleichtert das sichere Schließen solcher Schiebetüren erheblich und steigert daher den Bedienungskomfort für die Crew eines Hubschraubers wesentlich. Auch werden die ergonomischen Anforderungen an das Flugpersonal beim Flug des Hubschraubers mit offenen Schiebetüren für das Zuschieben der Tür im Flug wesentlich verringert.The inventive design of the door lock facilitates the safe closing of such sliding doors considerably and therefore significantly increases the ease of use for the crew of a helicopter. Also, the ergonomic requirements for the flight crew during flight of the helicopter with open sliding doors for sliding the door in flight are significantly reduced.

Die Erfindung ist nachfolgend anhand einer in der Zeichnung mehr oder minder schematisch dargestellten Ausführungsbeispiels beschrieben.The invention is described below with reference to an embodiment shown more or less schematically in the drawing.

Von einer Verriegelungsvorrichtung für die nicht dargestellte Schiebetür eines ebenfalls nicht dargestellten Luftfahrzeuges, insbesondere eines Hubschraubers, ist in den Fig. 1 bis 4 lediglich eine der mit der Schiebetür fest verbundenen Verriegelungsvorrichtungen 10 gezeigt. Die Verriegelungsvorrichtungen werden gemeinsam über ein ebenfalls nicht dargestelltes einen Handhebel aufweisendes Gestänge betätigt und wirken jeweils mit einem an der Rumpfstruktur des Luftfahrzeuges befestigten eine Raste 11 aufweisenden Beschlag 12 zusammen.From a locking device for the sliding door, not shown, of an aircraft, also not shown, in particular a helicopter is in the Fig. 1 to 4 only one of the locking device 10 fixedly connected to the sliding door is shown. The locking devices are operated together via a likewise not shown a hand lever exhibiting linkage and each cooperate with a fixed to the fuselage structure of the aircraft a detent 11 having fitting 12 together.

Mit der Struktur der nicht dargestellten Schiebetür ist ein Zahnstangenriegel 26 verbunden, an dessen wirksamem Ende über eine dort auf einem in Achsrichtung von einer Feder 14 beaufschlagten Stift 15 gelagerte Rolle 16 die Schiebetür verriegelbar ist. Hierzu greift die Rolle 16 hinter die Raste 11 des an der ebenfalls nicht dargestellten Rumpfstruktur befestigten Beschlages 12, der sich am hinteren Rahmenprofil der gleichfalls nicht dargestellten Schiebetürführung befindet. Als Fangfalle dient das freie Ende 15a des die Rolle 16 lagernden Stifts 15 des aus Fig. 3 ersichtlichen Zahnstangenriegels 26.With the structure of the sliding door, not shown, a rack bolt 26 is connected, at the effective end of which is mounted on a spring 15 acted upon in the axial direction by a spring 15 pin 16, the sliding door can be locked. For this purpose, the roller 16 engages behind the detent 11 of the attached to the hull structure also not shown fitting 12, which is located on the rear frame profile of the sliding door guide, also not shown. As a catch, the free end 15a of the roller 16 overlying pin 15 of the serves Fig. 3 apparent rack bolt 26.

Im Bereich des freien Endes 15a des Stiftes 15 des Zahnstangenriegels 26 der seitlich im Abstand zur Rumpfstruktur mittels Führungsschienen geführten Schiebetür befindet sich ein an der Rumpfstruktur am hinteren Türrahmenprofil befestigter Türfangbeschlag 20. Dieser umfasst einen in einer Basis 21 federn gelagerten Gleitstein 22 mit einer Fangschräge 23 an seiner Oberfläche und einer Öffnungsschräge 24, die der dem Stift 15 abgewandten Seitenfläche des Gleitsteins zugeordnet ist; vgl. Figuren 3 und 4. Über eine Feder wird der Gleitstein 22 in Anlage mit der dem Stift 15 zugewandten Seitenfläche 27 des Türfangbeschlages gehalten.In the region of the free end 15a of the pin 15 of the rack bolt 26 of the laterally spaced from the fuselage structure guided by guide rails sliding door is attached to the fuselage structure on the rear door frame profile door catch fitting 20. This includes a spring 21 mounted in a base sliding block 22 with a catch bevel 23rd on its surface and an opening bevel 24 which is associated with the side facing away from the pin 15 side surface of the sliding block; see. FIGS. 3 and 4 , About a spring of the sliding block 22 is held in contact with the pin 15 facing side surface 27 of the door catch fitting.

Da der federbeaufschlagte Stift 14 des Zahnstangenriegels 26 in seiner Achsrichtung längs beweglich gelagert ist, kann dieser sich, sofern der Türfangbeschlag 20 in Bezug auf den Stift 15a an der Rumpfstruktur bestimmungsgemäß ausgerichtet befestigt ist, mit seinem freien Ende 15 beim Zuschieben der Schiebetür von Hand über die Fangschräge 23 des Gleitsteines 22 bewegen. Wie erwähnt, wird hierbei die Schiebetür über ihre Führungsschienen in dem Bereich der Türöffnung in der Rumpfstruktur gegen die Türöffnung bewegt. Infolge dieser Bewegung verfängt sich also die Schiebetür hinter der Fangschräge 23 des Gleitsteines 22 des Türfangbeschlages 20. Die Schiebetür ist in dieser Lage "gefangen", kann sich also infolge Beschleunigungen oder Schräglagen des Hubschraubers nicht mehr in die Offenstellung zurückbewegen. Das Einstraken und Verriegeln der Schiebetür in der Türöffnung kann nunmehr ohne Zuhalten der Schiebetür von Hand erfolgen, und zwar allein durch Bewegen des nicht dargestellten Handgriffes des mit dem Zahnstangenriegel 26 verbundenen Gestänges in die Schließstellung. Hierbei bewegt sich das freie Ende 15 des Stiftes 15a federnd hinter die Öffnungsschräge 24 des Gleitsteines 22; vgl. Fig. 2.Since the spring-loaded pin 14 of the rack bolt 26 is mounted longitudinally movable in its axial direction, this can, if the door catch fitting 20 is fixed with respect to the pin 15a aligned to the fuselage structure intended, with its free end 15 when sliding the sliding door by hand the catch bevel 23 of the sliding block 22 move. As mentioned, in this case the sliding door is moved via its guide rails in the region of the door opening in the fuselage structure against the door opening. As a result of this movement, therefore, the sliding door gets caught behind the catching slope 23 of the sliding block 22 of the door catch fitting 20. The sliding door is "caught" in this position, so can not move back into the open position due to accelerations or inclinations of the helicopter. The Einstraken and locking the sliding door in the door opening can now be done without locking the sliding door by hand, solely by moving the handle, not shown, of the rod connected to the rack bar 26 linkage in the closed position. In this case, the free end 15 of the pin 15a moves resiliently behind the opening slope 24 of the sliding block 22; see. Fig. 2 ,

Beim Öffnen der Schiebetür, also nach dem Freigeben des Zahnstangenriegels 26, wird diese in ihren Führungsschienen aus der Türöffnung bewegt. Hierbei schiebt das freie Ende 15a des Stiftes 15 den Gleitstein 22 über die Öffnungsschräge 24 entgegen der Kraft der nicht dargestellten Feder aus der Führungsbahn der Schiebetür, so dass diese frei in die Offenstellung bewegbar ist. Nach dem Passieren der Schiebetür nimmt der Gleitstein 22 infolge der Feder seine "Fanglage" wieder ein.When you open the sliding door, so after releasing the rack bolt 26, this is moved in their guide rails out of the door opening. Here, the free end 15a of the pin 15 pushes the sliding block 22 over the opening slope 24 against the force of the spring, not shown, from the guide track the sliding door, so that it is free to move into the open position. After passing through the sliding door, the sliding block 22 resumes its "catching position" as a result of the spring.
