Femer sind an den U-Schenkeln elastische Auflaufteile abgestützt, die den über einen Einführungsschlitz in der Stirnwand eintretenden und dabei in der Gabel die Gabelfalle mitnehmenden Fangbolzen beim Schließen der zugeordneten Kraftfahrzeugtür aufnehmen, wobei die Auflaufteile während der gesamten Schließbewegung den Fangbolzen führen und der Fangbolzen bei der Schließbewegung der zugeordneten Kraftfahrzeugtür sowie in Schließstellung lediglich mit den Gabelschenkeln, nicht aber mit dem Gabelgrund Kontakt hat Zwar ist mit einem derartigen Schloss sicherlich eine hinreichende Geräuschdämpfung während des Schließens der Tür oder der Klappe erzielbar, jedoch sind während der Fahrt Geräusche in Form von sogenannten Knarzgeräuschen nicht auszuschließen, die in der Schließstellung des Schlosses aus einer Relativbewegung zwischen dem Schlossgehause bzw. der Drehfalle und dem Schließbügel oder Schließbolzen sowie der hier favorisierten Materialpaarung resultieren. So besteht die Federzunge, wie bereits oben erwähnt, aus einem Kunststoff, wogegen der Schließbügel oder Schließbolzen überwiegend aus einem Metall, insbesondere aus Stahl, gefertigt ist Eine derartige Materialpaarung verursacht aufgrund nicht zu vermeidender Ver-schmutzung, insbesondere aufgrund Verstaubung der zueinander korrespondierenden Reibflächen, besagte Knarzgeräusche, die ihrerseits auf einen an sich bekannten Stick-Slipp-Effekt, aiuch als Haftgleiteffekt oder Ruckgleiten bezeichnet, zurückzuführen sind. Hier setzt die nachfolgend beschriebene Erfindung an.From the DE 22 18 734 A1 is a motor vehicle door lock housing with known from the end face of the associated motor vehicle door U-profile with end wall and U-legs and connected to the U-leg cover plate, wherein in the U-profile on a mounted in the end wall and in the cover plate pivot pin Fork with existing fork legs and fork base existing fork is arranged and this is associated with a mounted in the end wall and in the cover plate pawl. Femer are supported on the U-legs elastic casserole parts that enter the entering via an insertion slot in the end wall and thereby take in the fork the fork catch catch when closing the associated motor vehicle door, the casserole parts during the entire closing movement lead the catch bolt and the catch bolt at the closing movement of the associated motor vehicle door and in the closed position only with the fork legs, but not with the fork base has contact Although with such a lock certainly sufficient noise attenuation during the closing of the door or the flap can be achieved, but noise in the form of so-called creaking noise can not be excluded while driving in the closed position of the castle from a relative movement between the lock housing and the catch and the striker or latch bolt and the material pairing favored here result. Thus, the spring tongue, as already mentioned above, made of a plastic, whereas the striker or locking bolt is mainly made of a metal, especially steel, made such a material combination caused due to unavoidable contamination, in particular due to dusting of mutually corresponding friction surfaces, said creaking noises, which in turn are referred to a known stick-slip effect, also referred to as stick-slip effect or stick-slip. This is where the invention described below begins.

Aufgabe der Erfindung ist es, ein Schloss derart zu verbessern, dass besagte Geräusche, insbesondere Knarzgeräusche, die in der Schließstellung des Schlosses aus einer Relativbewegung zwischen dem Schlossgehäuse bzw. der Drehfalle und dem Schließbügel oder Schließbolzen resultieren, vermieden, zumindest jedoch maßgeblich gemindert sind.The object of the invention is to improve a lock such that said noise, especially creaking noises, resulting in the closed position of the lock from a relative movement between the lock housing or the catch and the striker or locking pin, avoided, but at least significantly reduced.

Der Erfindung liegt die Erkenntnis zugrunde, dass die Materialpaarung der in Rede stehenden Reibungspartner, nämlich des Schließbügels oder Schließbolzens und der Federlippe so zu wählen ist, dass der vorstehend beschriebene Stick-Slipp-Effekt weitestgehend vermieden ist.The invention is based on the finding that the material pairing of the friction partners in question, namely the striker or striker and the spring lip is to be chosen so that the stick-slip effect described above is largely avoided.

Demgegenüber kann es jedoch auch angezeigt sein, das Platten- oder Profilelement während der Herstellung des Schlossgehäuses samt Federlippe aus Kunststoff in dieselbe bereits zu integrieren, woraus Einsparungen bei der Montage des Schlosses resultieren. Wird eine Auflage in Form eines Profilelementes gewählt, kann dasselbe vorteilhaft durch ein im Querschnitt offenes oder geschlossenes Hohlprofil mit zumindest einer mit dem Schließbügel oder Schließbolzen in Kontakt tretenden Profilwandung gebildet sein. Hierdurch ist die Montage der Auflage an der Federlippe komfortabel bewerkstelligbar.Advantageously, the plate or profile element may be formed as a separately manufactured attachment, which is inexpensively prefabricated and firmly connected during assembly of the lock with the spring lip. In contrast, however, it may also be appropriate to integrate the plate or profile element during the manufacture of the lock housing together with spring lip made of plastic in the same, resulting in savings in the assembly of the castle. If a support is selected in the form of a profile element, the same can advantageously be formed by a hollow profile which is open or closed in cross-section with at least one profile wall coming into contact with the striker or locking bolt. As a result, the assembly of the support on the spring lip is comfortable bewerkstelligbar.

Weiter vorteilhaft kann vorgesehen sein, dass die reibungsarme und verschleißfeste Oberfläche des Platten- oder Profilelementes durch eine Oberflächenbehandlung zur Erzielung einer geringen Rauhigkeit, durch eine Reibbeschichtung, wie elektrolytische Beschichtung mit einem reibungs- und verschleißarmen Werkstoff, und/oder durch jegliche andere geeignete und an sich bekannte Beschichtung mit einem reibungsarmen und verschleißfesten Werkstoff bewirkt ist. Im Rahmen umfangreicher Versuche hat sich besonders vorteilhaft, weil kostengünstig herstellbar, ein Platten- oder Profilelement aus einem Stahl, insbesondere Edelstahl, bewährt.Further advantageously, it may be provided that the low-friction and wear-resistant surface of the plate or profile element by a surface treatment to achieve a low roughness, by a friction coating, such as electrolytic coating with a friction and wear-resistant material, and / or by any other suitable and known coating is effected with a low-friction and wear-resistant material. In the context of extensive tests has proven to be particularly advantageous, because inexpensive to produce, a plate or profile element made of a steel, especially stainless steel proven.

Um nachteilige Schließgeräusche zu vermeiden, ist die Federlippe vorteilhafterweise derart ausgebildet und ist das Platten- oder Profilelement derart mit derselben verbunden, dass zumindest die mit dem Schließbügel oder Schließbolzen in Kontakt tretenden Oberflächen sowohl der Federlippe als auch des Platten- oder Profilelementes stufenlos aneinander anschließen. In weiterer vorteilhafter Ausgestaltung der Erfindung ist die Federlippe aus fertigungsökonomischen Gründen einstückig mit dem Schlossgehäuse ausgebildet.In order to avoid disadvantageous locking noises, the spring lip is advantageously designed and the plate or profile element is connected to the same so that at least connect with the striker or locking pins in contact surfaces of both the spring lip and the plate or profile element continuously connected to each other. In a further advantageous embodiment of the invention, the spring lip for manufacturing economic reasons is formed integrally with the lock housing.

Die Fig.1 und 2 zeigen vorliegend in einer äußerst schematischen Darstellung ein Schloss einer Tür 1 an einem Kraftfahrzeug, mit einem türseitig angeordneten Schlossgehäuse 2, an welchem eine Drehfalle 3 drehgelagert ist.The Fig.1 and 2 show in an extremely schematic representation of a lock of a door 1 on a motor vehicle, with a door side arranged lock housing 2, on which a rotary latch 3 is rotatably mounted.

Die Erfindung beschränkt sich jedoch nicht auf besagte Tür 1, sondern erfasst auch jegliche an sich bekannte und mittels eines Schlosses der erfindungsgemäßen Art verschließbare bzw. zu verschließende Klappe am Kraftfahrzeug (nicht näher dargestellt).However, the invention is not limited to said door 1, but also covers any known per se and by means of a lock of the type according to the invention closable or to be closed flap on the motor vehicle (not shown).

Die Drehfalle 3 wirkt mit einer an sich bekannten Sperrklinke 4 zusammen und ist vorliegend in der Schließstellung der Tür 1 respektive des Schlosses dargestellt, wobei ein ebenfalls an sich bekannter karosserieseitig angeordneter Schließbügel 5, welches auch ein nicht näher dargestellter Schließbolzen sein kann, von der Drehfalle 3 zumindest formschlüssig aufgenommen ist. Während des Schließvorganges wird der Schließbügel 5 innerhalb einer Führungskulisse 6 des Schlossgehäuses 2 geführt und schließlich von einem Fallenmaul 7 der Drehfalle 3 aufgenommen.The rotary latch 3 cooperates with a known pawl 4 and is presently shown in the closed position of the door 1 and the lock, wherein a likewise known per se body-side striker 5, which may also be a locking pin not shown, from the catch 3 is received at least positively. During the closing operation of the striker 5 is guided within a guide slot 6 of the lock housing 2 and finally received by a latch mouth 7 of the catch 3.

Einführungsseitig der besagten Führungskulisse 6 ist am Schlossgehäuse 2 zumindest eine in die Führungskulisse 6 längs hineinreichende, d. h., eine auskragende Federlippe 8 festgelegt, welche der federnden Abstützung des Schließbügels 5 in Schließstellung des Schlosses sowie während des Einführens des Schließbügels 5 in die oder Herausführens aus der Führungskulisse 6 und Drehfalle 3 respektive aus deren Fallenmaul 7 am Schlossgehäuse 2 dient. Wie bereits einleitend ausgeführt, ist aufgrund der Federlippe 8 vorteilhaft eine Dämpfung insbesondere von Schließ- und Klappergeräuschen zu verzeichnen.On the insertion side of said guide slot 6 is on the lock housing 2 at least one longitudinally extending into the guide slot 6, d. h., A projecting spring lip 8 is fixed, which serves the resilient support of the striker 5 in the closed position of the lock and during the insertion of the striker 5 in or Herausführens from the guide slot 6 and 3, respectively from the trap mouth latch housing 2. As already stated in the introduction, is due to the spring lip 8 advantageous to record a damping in particular of closing and rattling noises.

Das Schlossgehäuse 2 ist seinerseits aus einem Kunststoff, vorzugsweise aus einem thermoplastischen Kunststoff nach einem an sich bekannten Spritzgießverfahren einstückig mit der Federlippe 8 hergestellt. Der Schließbügel 5 besteht überwiegend aus einem an sich bekannten Edelstahl.The lock housing 2 is in turn made of a plastic, preferably made of a thermoplastic material according to a known injection molding in one piece with the spring lip 8. The striker 5 consists predominantly of a known stainless steel.

Eine derartige Materialpaarung verursacht jedoch aufgrund nicht zu vermeidender Verschmutzung, insbesondere aufgrund Verstaubung der zueinander korrespondierenden Reibflächen, unangenehme Knarzgeräusche, die ihrerseits auf einen an sich bekannten Stick-Slipp-Effekt, auch als Haftgleiteffekt oder Ruckgleiten bezeichnet, zurückzuführen sind.However, such a combination of materials caused due to unavoidable contamination, especially due to dusting of mutually corresponding friction surfaces, unpleasant creaking noises, which in turn referred to a known stick-slip effect, also referred to as stick-slip effect or jerk.

Um diesem nachteiligen Umstand zu begegnen, weist die Federlippe 8 zumindest in dem Bereich ihres freien Endes, welcher der End- und Abstützposition 9 des Schließbügels 5 in Schließstellung des Schlosses entspricht (vgl. insbes. Fig. 1), eine Auflage 10 mit einer reibungsarmen und verschleißfesten Oberfläche auf (Fig. 3).To counter this disadvantageous circumstance, the spring lip 8 at least in the region of its free end, which corresponds to the end and support position 9 of the striker 5 in the closed position of the castle (see. Fig. 1 ), a support 10 with a low-friction and wear-resistant surface on ( Fig. 3 ).

Vorliegend ist die Auflage 10 durch ein mit der Federlippe 8 fest verbundenes Profilelement als separat hergestelltes Anbauteil mit einem im Querschnitt geschlossenen Hohlprofil in Form eines Kastenprofils gebildet (Fig. 5), welches auf das entsprechend vorbereitete freie Ende der Federlippe 8, dieselbe voll umfänglich umschließend, axial aufgeschoben ist.In the present case, the support 10 is formed by a profile element fixedly connected to the spring lip 8 as a separately produced attachment with a closed hollow profile in the form of a box profile ( Fig. 5 ), which on the suitably prepared free end of the spring lip 8, the same fully enclosing circumferentially, is pushed axially.

Die besagte Auflage 10 in Form eines Kastenprofils besteht bevorzugt aus einem Edelstahl und verfügt über nicht näher dargestellte, jedoch an sich bekannte und mit der Auflage 10 einstückig ausgebildete Rastmittel in Form einer oder mehrerer Rastverzahnungen, die ihrerseits während der Bestückung der Federlippe 8 mit der Auflage 10 respektive dem Kastenprofil in die Federlippe 8 aus Kunststoff, einen Formschluss mit derselben eingehend, eindringen.The said support 10 in the form of a box section preferably consists of a stainless steel and has not shown, but known per se and with the support 10 integrally formed latching means in the form of one or more locking teeth, which in turn during the assembly of the spring lip 8 with the support 10 respectively the box profile in the spring lip 8 made of plastic, a positive engagement with the same incoming, penetrate.

Zumindest die mit dem Schließbügel 5 in Kontakt tretende Profilwandung 10a der Auflage 10 verfügt über eine reibungsarme und verschleißfeste Oberfläche, die ihrerseits durch eine Oberflächenbehandlung zur Erzielung einer möglichst geringen Rauhigkeit, durch eine auf die Oberfläche zusätzlich aufgebrachte Reibbeschichtung, beispielsweise realisiert durch elektrolytische Beschichtung mit einem an sich bekannten geeigneten reibungsarmen und verschleißfesten Werkstoff, und/oder durch jegliche andere geeignete und an sich bekannte Beschichtung mit einem reibungsarmen und verschleißfesten Werkstoff bewirkt ist.At least the contact with the striker 5 in contact profile wall 10a of the support 10 has a low-friction and wear-resistant surface, in turn, by a surface treatment to achieve the lowest possible roughness, by an additionally applied to the surface friction coating, for example, realized by electrolytic coating with a known suitable low-friction and wear-resistant material, and / or caused by any other suitable and known per se coating with a low-friction and wear-resistant material.

Wie insbesondere der Fig. 4 zu entnehmen ist, verfügt der Bereich der Federlippe 8, welcher der End- und Abstützposition 9 des Schließbügels 5 in Schließstellung des Schlosses entspricht, respektive deren freies Ende über einen Absatz 11, an dem sich ein Abschnitt des freien Endes der Federlippe 8 mit geminderter Materialstärke anschließt.How the particular Fig. 4 can be seen, the region of the spring lip 8, which corresponds to the end and support position 9 of the striker 5 in the closed position of the castle, respectively, the free end of a paragraph 11, at which a portion of the free end of the spring lip 8 with reduced material thickness followed.

Auf diesen Endabschnitt ist die Auflage 10 festgelegt. Der Absatz 11 ist dabei derart gewählt, dass zumindest die mit dem Schließbügel 5 in Kontakt tretenden Oberflächen sowohl der Federlippe 8 als auch der Auflage 10 in Form des vorliegend kastenförmigen Profilelementes stufenlos aneinander anschließen.At this end portion of the support 10 is fixed. The paragraph 11 is chosen such that at least connect with the striker 5 in contact surfaces of both the spring lip 8 and the support 10 in the form of the present box-shaped profile element steplessly connected to each other.

Vorstehendes bevorzugtes Ausführungsbeispiel stellt auf eine Auflage 10 aus Edelstahl mit einem kastenförmigen Profilquerschnitt ab, welche formschlüssig mit dem freien Ende der Federlippe 8 verbunden ist.The above preferred embodiment is based on a support 10 made of stainless steel with a box-shaped profile cross-section, which is positively connected to the free end of the spring lip 8.

Die Erfindung beschränkt sich jedoch nicht auf dieses Ausführungsbeispiel, sondern erfasst auch für den Fachmann leicht nachvollziehbare und demgemäß nicht näher dargestellte Auflagen 10, die ihrerseits plattenförmig ausgebildet oder durch ein im Querschnitt offenes Hohlprofil gebildet sind. Ferner können die Auflagen 10 auch kraft- und/oder stoffschlüssig, beispielsweise durch Klebung, mit der Federlippe 8 fest verbunden sein. Des Weiteren kann es auch angezeigt sein, für die Ausbildung der Auflage 10 statt eines Edelstahls einen anderen, vorstehend beschriebenen Ansprüchen hinsichtlich Reibungsarmut und Verschleißfestigkeit genügenden Werkstoff, wie beispielsweise einen geeigneten Kunststoff oder eine Keramik in Anwendung zu bringen. Ebenso kann es sich auch als vorteilhaft erweisen, die Auflage 10 in die Federlippe 8 zu integrieren, indem die Auflage 10 zweckmäßigerweise während der Herstellung des Schlossgehäuses 2 samt Federlippe 8 aus Kunststoff durch spritzgießen bereits mit in die Federlippe 8 eingegossen wird, so dass diesbezügliche Montageschritte während der Montage bzw. Bestückung des Schlosses mit Anbauteilen vorteilhaft vermieden werden.However, the invention is not limited to this embodiment, but also covers for the skilled person easily comprehensible and accordingly not shown pads 10, which in turn are plate-shaped or formed by a cross-sectionally open hollow profile. Furthermore, the supports 10 may also be non-positively and / or materially bonded, for example by gluing, firmly connected to the spring lip 8. Furthermore, it may also be appropriate for the embodiment of the support 10, instead of a stainless steel, to apply another material which satisfies the above-described requirements with respect to low-friction and wear-resistant material, for example a suitable plastic or a ceramic. Likewise, it may also prove advantageous to integrate the support 10 in the spring lip 8 by the support 10 is suitably poured by injection molding during the manufacture of the lock housing 2 together with spring lip 8 made of plastic already in the spring lip 8, so that related assembly steps be advantageously avoided during assembly or assembly of the castle with attachments.
