Description

Die Erfindung betrifft ein Kraftfahrzeug-Türschloß nach dem Oberbegriff von Anspruch 1. Das bekannte Kraftfahrzeug-Türschloß, von dem die Erfindung ausgeht (US-A-4 538 845), zeigt eine Gehäusekonstruktion mit einem aus Kunststoff bestehenden Mittelteil. Diese Gehäusekonstruktion bietet bei einer erheblichen Vereinfachung eine hohe Flexibilität hinsichtlich der Aufnahme von mehreren mechanischen und elektrischen Teilen. Gleichzeitig läßt sich hier das Konzept einer allseitigen Kapselung, das hinsichtlich Verschmutzungen, Eindringen von Feuchtigkeit usw. zweckmäßig ist, ohne weiteres verwirklichen.The invention relates to a motor vehicle door lock according to the preamble of claim 1. The known motor vehicle door lock from which the invention is based (US-A-4 538 845) shows a housing construction with a plastic middle part. With a considerable simplification, this housing construction offers a high degree of flexibility with regard to the accommodation of several mechanical and electrical parts. At the same time, the concept of encapsulation on all sides, which is expedient with regard to contamination, penetration of moisture, etc., can be easily implemented here.

Bei der zuvor erläuterten bekannten Gehäusekonstruktion sind trotz des dort vorhandenen, aus Kunststoff bestehenden Mittelteils und trotz der dort vorhandenen, auf beiden Seiten des Mittelteils angeordneten Abdeckplatten mechanischen und elektrischen/elektronischen Teile in ganz üblicher Weise durch separate Befestigungselemente wie Schrauben und Bolzen oder auch Niete befestigt.In the case of the known housing construction explained above, mechanical and electrical / electronic parts are fastened in a very customary manner by separate fastening elements such as screws and bolts or rivets in spite of the plastic part and the cover plates provided on both sides of the middle part .

Bei mehrteiligen Schloßkonstruktionen ist es ebenfalls und seit längerem bekannt, entsprechende Teile mit gesonderten Befestigungselementen zu befestigen (DE-C-3 526 501).In the case of multi-part lock constructions, it has also been known for some time to fasten corresponding parts with separate fastening elements (DE-C-3 526 501).

Aus einem nicht vorveröffentlichten Stand der Technik (DE-A-3 717 778) ist es im übrigen bekannt, ein Kraftfahrzeug-Türschloß durch Verwendung eines als Nuß gestalteten Kraftangriffselements mit zugeordnetem, koaxial angeordnetem Zwischenelement so zu konstruieren, daß auf mechanische Weise eine Unterscheidung zwischen Innensicherung und Außensicherung bei Priorität der Außensicherung möglich ist und gleichzeitig ein Mikroschalter-Steuerung durch eine solche Nuß in der Schließmechanik erfolgt, um eine Komfortschaltung auszulösen. Auch ist es möglich, das zusätzliche Zwischenelement dazu zu nutzen, zwischen einer normalen Sicherungsstellung und einer Diebstahlsicherungsstellung zu unterscheiden.From a non-prepublished prior art (DE-A-3 717 778) it is also known to construct a motor vehicle door lock by using a force-engaging element designed as a nut with an associated coaxially arranged intermediate element so that a mechanical distinction can be made between Internal security and external security with priority of the external security is possible and at the same time a microswitch is controlled by such a nut in the locking mechanism in order to trigger a convenience circuit. It is also possible to use the additional intermediate element to differentiate between a normal security position and an anti-theft security position.

Der Erfindung liegt die Aufgabe zugrunde, das bekannte eingangs erläuterte Kraftfahrzeug-Türschloß so auszugestalten und weiterzubilden, daß es unter Nutzung der vorgegebenen Gehäusekonstruktion weiter vereinfacht ist.The invention is based on the object of designing and developing the known motor vehicle door lock explained at the outset in such a way that it is further simplified using the predetermined housing construction.

Die zuvor aufgezeigte Aufgabe ist bei einem Kraftfahrzeug-Türschloß nach dem Oberbegriff von Anspruch 1 durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst. Die das Mittelteil auf der Außenseite abdeckende Abdeckplatte wird als aktives Befestigungselement für die Nuß genutzt, separate Befestigungselemente können insoweit entfallen.The object presented above is achieved in a motor vehicle door lock according to the preamble of claim 1 by the features of the characterizing part of claim 1. The cover plate covering the middle part on the outside is used as an active fastening element for the nut, separate fastening elements can be omitted in this respect.

Wesentliche Bedeutung kommt auch der Lehre von Anspruch 2 zu. Unter Nutzung der erfindungsgemäßen Gehäusekonstruktion wird hier auf sehr einfache Weise die Forderung erfüllt, daß die Sicherungshebel nicht betätigt werden können, wenn sich die Schloßfalle in Öffnungsstellung befindet, also die Tür geöffnet ist. Dies geschieht einfach durch die Blockierung der Bewegungsbahn des Blockierarms an der das Kraftangriffselement für die Sicherungshebel bildenden Nuß.The teaching of claim 2 is also of significant importance. Using the housing construction according to the invention, the requirement is met in a very simple manner that the safety levers cannot be actuated when the lock latch is in the open position, that is to say the door is open. This is done simply by blocking the path of movement of the blocking arm on the nut forming the force application element for the safety lever.

Weitere bevorzugte Ausgestaltungen sind in den nicht im einzelnen erwähnten Unteransprüchen beschrieben. Im übrigen wird die Erfindung nachfolgend in Verbindung mit der Erläuterung eines bevorzugten Ausführungsbeispiels anhand der Zeichnung nochmals im Detail erläutert. In der Zeichnung zeigt

  • Fig. 1 das Mittelteil des Gehäuses eines erfindungsgemäßen Kraftfahrzeug-Türschlosses von der Vorderseite, also der für die Schließelemente vorgesehenen Seite aus gesehen,
  • Fig. 2 den Gegenstand aus Fig. 1 von der Rückseite, also von der Seite der Schließmechanik her gesehen, und
  • Fig. 3 die Ansicht 111 aus Fig. 2, als Schnittdarstellung 111-111 im Bereich der Aufnahme für das Kraftangriffselement.
Further preferred configurations are described in the subclaims not mentioned in detail. Otherwise, the invention is explained again in detail in connection with the explanation of a preferred exemplary embodiment with reference to the drawing. In the drawing shows
  • 1 the central part of the housing of a motor vehicle door lock according to the invention seen from the front, that is to say from the side provided for the locking elements,
  • Fig. 2 seen the object of Fig. 1 from the back, that is from the side of the locking mechanism, and
  • 3 shows the view 111 from FIG. 2, as a sectional illustration 111-111 in the region of the receptacle for the force application element.

In den Fig. 1 bis 3 der Zeichnung ist nur das Mittelteil des Gehäuses eines erfindungsgemäßen Kraftfahrzeug-Türschlosses zusammen mit einem eingelegten Kraftangriffselement dargestellt. Alle Schließelemente sowie alle sonstigen Teile der Schließmechanik einschließlich entsprechender Mikroschalter usw. sind nicht eingezeichnet.1 to 3 of the drawing, only the middle part of the housing of a motor vehicle door lock according to the invention is shown together with an inserted force application element. All locking elements as well as all other parts of the locking mechanism including corresponding microswitches etc. are not shown.

Ein Kraftfahrzeug-Türschloß, dessen Gehäuse in Fig. 1 dargestellt ist, ist insbesondere für eine von außen abschließbare Tür eines Kraftfahrzeuges, beispielsweise die Fahrertür, geeignet. In etwas modifizierter Ausführung kann es aber auch für Hecktüren, sogar für Heckklappentüren usw. verwendet werden. In dem Gehäuse eines solchen Kraftfahrzeug-Türschlosses sind üblicherweise Schließelemente wie Schloßfalle und Sperrklinke sowie eine Schließmechanik, u. a. mit einem Innenauslösehebel, einem Außenauslösehebel, einem Innensicherungshebel, ggf. einem von außen her bewegten Außensicherungshebel und einem Kraftangriffselement, auf den der Innensicherungshebel und, so vorhanden, auch der Außensicherungshebel wirkt, angeordnet. Erkennbar sind in Fig. 1 und Fig. 2 Durchgangsöffnungen 1, 2 für Lagerbolzen der Schloßfalle und der Sperrklinke sowie ein Einlaufschlitz 3 für einen nicht dargestellten Schließkloben.A motor vehicle door lock, the housing of which is shown in FIG. 1, is particularly suitable for a door of a motor vehicle which can be locked from the outside, for example the driver's door. In a slightly modified version, it can also be used for rear doors, even for tailgate doors, etc. In the housing of such a motor vehicle door lock are usually locking elements such as a lock latch and pawl and a locking mechanism, u. a. with an inner release lever, an outer release lever, an inner safety lever, possibly an outer safety lever moved from the outside and a force application element on which the inner safety lever and, if present, also the outer safety lever acts. Through openings 1, 2 for bearing bolts of the lock latch and the pawl and an inlet slot 3 for a locking block, not shown, can be seen in FIGS. 1 and 2.

Erkennbar ist nun zunächst, daß das Gehäuse aus einem einstückig aus Kunststoff geformten Mittelteil 4 und einer vorderen und hinteren Abdeckplatte besteht, daß das Mittelteil 4 eine mittige, mit notwendigen Durchbrechungen 5, 6 versehene Tragwand 7 und zumindest auf der einen Seite von der Tragwand 7 abragende, einen bis auf notwendige Öffnungen umlaufenden Rand 8 sowie verschiedene Aufnahmen 9 bildende Stege 10 aufweist, daß die entsprechende Abdeckplatte auf den Rand 8 und soweit wie erforderlich auch auf die Stege 10 abdichtend aufsetzbar ist und daß auf der einen Seite der Tragwand 7 in den dort von Rand 8 und Stegen 10 gebildeten Aufnahmen 9 im wesentlichen die Teile der Schließmechanik und auf der anderen Seite der Tragwand 7 im wesentlichen die Schließelemente angeordnet sind. Vorgesehen ist dabei, daß Rand 8 und Stege 10 auch auf der anderen Seite der Tragwand 7 angeordnet sind und dort auch entsprechende Aufnahmen 9 bilden, in denen dann die Schließelemente angeordnet sind. Primär ist allerdings der Schutz der Schließmechanik gegen Staub und Feuchtigkeit. In Fig. 3 ist durch Pfeile 11 angedeutet, wie die ansonsten nicht dargestellten Abdeckplatten zur Schließung des Gehäuses auf das Mittelteil 4 aufgesetzt werden. Die Abdeckplatten bestehen hier aus Metall, das muß aber nicht so sein. Das Mittelteil 4 stellt den einteiligen Kern des Gehäuses dar, durch die Gestaltung mit Tragwand 7 und nach beiden Seiten abragenden Rändern 8 und Stegen 10 hat dieses Gehäuse aber gleichwohl zwei ganz klar voneinander getrennte und gegeneinander abgedichtete Sektionen. Nur die nötigsten Durchbrechungen 5, 6, nämlich eine Durchbrechung 5 für einen Mitnehmerzapfen der Sperrklinke und eine Durchbrechung 6, deren Zweck weiter unten noch näher erläutert wird, sind in der Tragwand 7 vorgesehen. Integriert in das Mittelteil 4 des Gehäuses sind auch die erforderlichen Dämpfungspuffer 12, die hier aus weicherem Kunststoff bestehend unmittelbar in das insoweit als Spritzgußform dienende Mittelteil 4 des Gehäuses eingespritzt sind.It can now be seen that the housing consists of a one-piece molded plastic middle part 4 and a front and rear cover plate, that the middle part 4 has a central, provided with necessary openings 5, 6 supporting wall 7 and at least on one side of the supporting wall 7 protruding, extending to the necessary openings edge 8 and various receptacles 9 webs 10 that the corresponding cover plate on the edge 8 and as far as necessary on the webs 10 is sealingly placed and that on one side of the supporting wall 7 in the receptacles 9 formed there by the edge 8 and webs 10 essentially the parts of the locking mechanism and on the other side of the support wall 7 essentially the closing elements are arranged. It is provided that the edge 8 and webs 10 are also arranged on the other side of the supporting wall 7 and there also form corresponding receptacles 9, in which the closing elements are then arranged. Protection of the locking mechanism against dust and moisture is of primary importance. In Fig. 3 by arrows 11 indicates how the otherwise not shown cover plates for closing the housing are placed on the middle part 4. The cover plates are made of metal here, but this need not be the case. The middle part 4 represents the one-piece core of the housing, but due to the design with the support wall 7 and edges 8 and webs 10 projecting on both sides, this housing nevertheless has two clearly separated and mutually sealed sections. Only the most necessary openings 5, 6, namely an opening 5 for a driving pin of the pawl and an opening 6, the purpose of which will be explained in more detail below, are provided in the supporting wall 7. The required damping buffers 12 are also integrated into the middle part 4 of the housing and are made of softer plastic and are injected directly into the middle part 4 of the housing, which serves as an injection mold.

Eine besonders gute Abdichtung der kritischen Stellen der Schließmechanik ergibt sich im dargestellten Ausführungsbeispiel dadurch, daß die Aufnahmen 9 für Lagerstellen von Teilen der Schließmechanik und für Elektroschalter mit Ausnahme von lediglich den erforderlichen Durchbrechungen allseits von Rand 8 und Stegen 10 umschlossen sind. Im übrigen läßt insbesondere Fig. 2 erkennen, daß im Bereich der Durchgangsöffnungen 1, 2 für die Lagerbolzen der Schloßfalle und der Sperrklinke die diese Durchgangsöffnungen 1, 2 umgebenden Stege 10 bis zur Anlage an die entsprechende Abdeckplatte hochgezogen sind, so daß diese Stege 10 gewissermaßen Abdichtungs- und Gleithülsen bilden, die die entsprechenden Metall-Lagerbolzen umgeben.A particularly good seal of the critical points of the locking mechanism results in the illustrated embodiment in that the receptacles 9 for bearing parts of parts of the locking mechanism and for electrical switches are enclosed on all sides by edge 8 and webs 10 with the exception of only the required openings. 2 shows in particular that in the area of the passage openings 1, 2 for the bearing bolts of the lock latch and the pawl, the passage openings 1, 2 surrounding webs 10 are pulled up to rest against the corresponding cover plate, so that these webs 10 to a certain extent Form sealing and sliding sleeves that surround the corresponding metal bearing bolts.

Nicht dargestellt ist in den Figuren im übrigen, daß nach bevorzugter Lehre die Abdeckplatten zu Durchbrechungen in Rand und Stegen des Mittelteils korrespondierende Komplementärausformungen aufweisen. Durch entsprechende Gestaltung der Komplementärausformungen an den Abdeckplatten lassen sich bestimmte Gestaltungen der Durchbrechungen realisieren und Fixierungswirkungen für verschiedene Teile im Mittelteil des Gehäuses erzielen.It is not shown in the figures that, according to preferred teaching, the cover plates have complementary shapes corresponding to openings in the edge and webs of the central part. By designing the complementary shapes on the cover plates, certain designs of the openings can be realized and fixing effects for different parts in the middle part of the housing can be achieved.

In der eingangs erläuterten älteren, nachveröffentlichten Patentanmeldung wird beschrieben, wie ein Kraftangriffselement für Innensicherungshebel und Außensicherungshebel als Nuß ausgeführt sein kann. Auch im vorliegenden Ausführungsbeispiel ist das Kraftangriffselement der Schließmechanik als in einem Lager drehbare Nuß 13 ausgeführt. Wesentlich ist hierbei nun zunächst, daß die das Kraftangriffselement bildende Nuß 13 mit ihrer Drehachse parallel zur Tragwand 7 des Mittelteils 4 angeordnet ist und einen radial abragenden Blockierarm 14 aufweist, daß der Blockierarm 14 die Tragwand 7 in einer Durchbrechung 6 durchsetzt und auf der anderen Seite der Tragwand 7 in die Bewegungsbahn 15 der Schloßfalle bzw. einer an der Schloßfalle ausgebildeten Steuerkulisse ragt und daß die Schloßfalle bzw. die Steuerkulisse bei in Öffnungsstellung befindlicher Schloßfalle vor der Durchbrechung 6 steht und eine Drehung der Nuß 13 über den Blockierarm 14 blockiert. Die Vorteile dieser Direktblockierung des Kraftangriffselements durch die hier nicht eingezeichnete Schloßfalle bzw. eine an der Schloßfalle ausgebildete Steuerkulisse sind im allgemeinen Teil der Beschreibung erläutert worden. Die zuvor erläuterte Blockierwirkung wird natürlich in gleicher Weise auch dann erreicht, wenn der Blockierarm 14 nicht unmittelbar in die Bewegungsbahn der Schloßfalle reicht, sondern mit einem weiteren Hebel bewegungsgekuppelt ist, der seinerseits in die Bewegungsbahn der Schloßfalle ragt.In the older, later published patent application explained at the beginning it is described how a force application element for the inner locking lever and the outer locking lever can be designed as a nut. In the present exemplary embodiment, too, the force application element of the locking mechanism is designed as a nut 13 which can be rotated in a bearing. It is essential here first that the nut 13 forming the force application element is arranged with its axis of rotation parallel to the supporting wall 7 of the middle part 4 and has a radially protruding blocking arm 14 that the blocking arm 14 passes through the supporting wall 7 in an opening 6 and on the other side the supporting wall 7 protrudes into the movement path 15 of the lock latch or a control link formed on the lock latch and that the lock latch or control link is in front of the opening 6 when the lock latch is in the open position and blocks rotation of the nut 13 via the blocking arm 14. The advantages of this direct blocking of the force application element by the lock latch not shown here or a control link formed on the lock latch have been explained in the general part of the description. The blocking effect explained above is of course also achieved in the same way if the blocking arm 14 does not extend directly into the path of movement of the lock latch, but is coupled with a further lever, which in turn protrudes into the path of movement of the lock latch.

Fig. 1 und Fig. 2 unterscheiden sich hinsichtlich der Lage der Nuß 13 insoweit, als in Fig. 1 die Nuß 13 in ihrer vollständig eingeschwenkten Stellung, also Entsicherungsstellung, gezeigt ist, während in Fig. 2 die Nuß 13 in einer teilweise ausgeschwenkten Stellung, also mit einem Blockierarm 14, der die Bewegungsbahn 15 soeben passiert, dargestellt ist.1 and 2 differ with regard to the position of the nut 13 insofar as the nut 13 is shown in its fully swiveled-in position, that is to say the unlocking position, in FIG. 1, while the nut 13 in a partially swiveled-out position in FIG. 2 , that is to say with a blocking arm 14, which has just passed the movement path 15.

Wegen der besonders geschickten Gestaltung des Mittelteils 4 des Gehäuses kann das Lager der Nuß 13 unmittelbar von einer eine entsprechende Lagerfläche 16 aufweisenden Aufnahme 9 gebildet sein. Die Nuß 13 ist lose in das Lager eingelegt und die Fixierung der Nuß 13 im Lager - unter Erhaltung der Drehbarkeit der Nuß 13 im Lager - erfolgt durch die nicht dargestellte, aufgesetzte Abdeckplatte. Insbesondere kann diese Fixierung durch eine Komplementärausformung an der Abdeckplatte erfolgen, beispielsweise eine Komplementärausformung, die ebenfalls entsprechende Lagerflächen für die Nuß 13 aufweist, so daß die Drehbarkeit der Nuß 13 trotz der Fixierung vollauf erhalten bleibt.Because of the particularly clever design of the middle part 4 of the housing, the bearing of the nut 13 can be formed directly by a receptacle 9 having a corresponding bearing surface 16. The nut 13 is loosely inserted in the bearing and the fixing of the nut 13 in the bearing - while maintaining the rotatability of the nut 13 in the bearing - is carried out by the cover plate (not shown). In particular, this fixation can be carried out by a complementary shape on the cover plate, for example a complementary shape, which also has corresponding bearing surfaces for the nut 13, so that the rotatability of the nut 13 is fully despite the fixation preserved.

Das dargestellte Mittelteil 4 des Gehäuses eines Kraftfahrzeug-Türschlosses ist dazu vorbereitet, daß mindestens eine weitere Nuß in einem von einer weiteren Aufnahme gebildeten Lager und, vorzugsweise, koaxial zur ersten Nuß angeordnet ist. Die weitere Nuß ist allerdings hier nicht eingesetzt. Es empfiehlt sich dabei, wie hier dargestellt, beide Nüsse mit ihrer Drehachse parallel zur Tragwand des Mittelteils anzuordnen und eine Drehantriebswelle beide Nüsse durchsetzen zu lassen. Mit der weiteren Nuß kann dann unabhängig von der ersten Nuß 13 eine Steuerfunktion in Verbindung mit einem Elektroschalter od. dgl. ausgeführt werden.The illustrated central part 4 of the housing of a motor vehicle door lock is prepared so that at least one further nut is arranged in a bearing formed by a further receptacle and, preferably, coaxially with the first nut. However, the additional nut is not used here. It is advisable, as shown here, to arrange both nuts with their axis of rotation parallel to the supporting wall of the middle section and to let a rotary drive shaft push through both nuts. With the additional nut, a control function in connection with an electrical switch or the like can then be carried out independently of the first nut 13.

Sind Elektroschalter als Teile der Schließmechanik vorgesehen, so empfiehlt es sich, auch diese lose in entsprechende Aufnahmen 9 am Mittelteil 4 einzulegen und in den Aufnahmen 9 durch die aufgesetzte Abdeckplatte zu fixieren. Im dargestellten Ausführungsbeispiel könnte beispielsweise die zweite Nuß im Bereich 17 eingesetzt sein und einen Elektroschalter betätigen, der in der darunter erkennbaren, vorspringenden Aufnahme 9 angeordnet ist. Die Aufnahme für den Elektroschalter grenzt in diesem Fall unmittelbar an die Aufnahme für die entsprechende Nuß an.If electrical switches are provided as parts of the locking mechanism, it is advisable to insert them loosely into the corresponding receptacles 9 on the central part 4 and to fix them in the receptacles 9 by means of the cover plate. In the exemplary embodiment shown, the second nut could, for example, be inserted in the region 17 and actuate an electrical switch which is arranged in the projecting receptacle 9 which can be seen below. In this case, the receptacle for the electrical switch is immediately adjacent to the receptacle for the corresponding nut.
