Description

Die Erfindung betrifft einen Schließzylinder für einen Kraftfahrzeug-Türverschluß gemäß den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a locking cylinder for a motor vehicle door lock according to the features of the preamble of claim 1.

Ein derartiger Schließzylinder ist beispielsweise aus der DE-GM 77 18 175 bekannt. Dabei ist der Schließzylinder mit einer relativ dünnen metallischen Abschlußkappe, die die Schlüsselkanalmündung oder den Schlüsselschlitz enthält, versehen. Auf der Innenseite der Abschlußkappe ist diese durch eine dickwandige elastische Dichtscheibe aus Kunststoff verstärkt. Um zu vermeiden, daß in den Schlüsselkanal Staub oder Feuchtigkeit eindringen kann, ist die Schlüsselkanalmündung von dem Schließzylinderinnenraum aus mit einer Kunststoff-Abdeckklappe verschließbar, wobei ein als Dichtlippe ausgebildetes Teil der elastischen Dichtscheibe (Formdichtung) gegen die Abdeckklappe drückt und ein randseitiges Eindringen von Staub etc. in den Schlüsselkanal verhindert. Beim Einführen des Schlüsselschaftes in den Schlüsselkanal wird die Abdeckklappe entgegen der Kraft einer Rückstellfeder um eine seitlich von dem Schlüsselkanal angeordnete Achse aus der Verschlußstellung herausgeschwenkt.Such a locking cylinder is known for example from DE-GM 77 18 175. The lock cylinder is provided with a relatively thin metallic end cap, which contains the key channel mouth or the key slot. On the inside of the end cap, this is reinforced by a thick-walled elastic sealing washer made of plastic. To prevent dust or moisture from penetrating into the key channel, the key channel mouth can be closed from the inside of the lock cylinder with a plastic cover flap, whereby a part of the elastic sealing disk (molded seal) designed as a sealing lip presses against the cover flap and an ingress of dust on the edge etc. prevented in the key channel. When the key shaft is inserted into the key channel, the cover flap is pivoted out of the locking position against the force of a return spring about an axis arranged laterally from the key channel.

Nachteilig ist bei diesem bekannten Schließzylinder vor allem, daß die unter der Abschlußkappe angeordnete Formdichtung sehr stabil sein muß. Durch dieses Erfordernis wird die Dichtkante häufig wellig. Eine plane Auflage der Abdeckklappe ist daher nicht gewährleistet, da ein Spalt zwischen Abschlußkappe und Dichtung sowie ein Spalt zwischen Abdeckklappe und Dichtung entstehen kann. Außerdem besteht die Gefahr, daß der Schlüssel mit seiner Außenkante an der Dichtlippe entlang schabt und somit die Dichtlippe zerstört und die erforderliche Abdichtung immer schlechter wird. Nachteilig ist bei den bekannten Schließzylindern schließlich die Verwendung der relativ viel Platz benötigenden Dichtscheibe. Insbesondere bei der Verwendung von dickwandigen Stahl-Abschlußkappen, wie sie aus (Diebstahl-) Sicherheitsgründen erforderlich sind, benötigen die bekannten Schließzylinder sehr viel Platz für die Abschlußkappe mit der darin befindlichen Dichtscheibe.A disadvantage of this known locking cylinder is above all that the molded seal arranged under the end cap must be very stable. Due to this requirement, the sealing edge is often wavy. A flat support of the cover flap is therefore not guaranteed, since there may be a gap between the end cap and the seal and a gap between the cover flap and the seal. There is also the risk that the key with its outer edge scrapes along the sealing lip and thus destroys the sealing lip and the required sealing becomes worse and worse. A disadvantage of the known locking cylinders is the use of the sealing disk, which requires a relatively large amount of space. Particularly when using thick-walled steel end caps, as are required for (theft) security reasons, the known locking cylinders require a great deal of space for the end cap with the sealing washer located therein.

Aus der DE 35 38 279 C2 ist ein Schließzylinder mit einer die Schlüsselkanalmündung verdeckenden Metall-Abdeckklappe bekannt. Dabei liegt die Abdeckklappe direkt an der ebenfalls aus einem Metallblech bestehenden Abschlußkappe an.From DE 35 38 279 C2, a locking cylinder with a metal cover flap covering the key channel mouth is known. The cover flap lies directly on the end cap, which is also made of sheet metal.

Nachteilig ist bei diesen bekannten Schließzylindern, daß die Metall-Dichtung abhängig ist von der Ebenheit der Teile. Eine ausreichende Ebenheit der Teile kann häufig durch die zur Herstellung dieser Teile erforderlichen Schneid- und Biegevorgänge aber nicht gewährleistet werden.A disadvantage of these known locking cylinders is that the metal seal is dependent on the flatness of the parts. Adequate flatness of the parts can often not be guaranteed by the cutting and bending processes required to produce these parts.

Der Erfindung liegt die Aufgabe zugrunde, einen Schließzylinder der eingangs erwähnten Art anzugeben, bei dem die zwischen Abdeckklappe und Abschlußkappe angeordnete elastische Dichtung ein Eindringen von Staub, Feuchtigkeit etc. in den Schlüsselkanal sicher verhindert.The invention has for its object to provide a lock cylinder of the type mentioned, in which the elastic seal arranged between the cover flap and end cap reliably prevents the ingress of dust, moisture, etc. into the key channel.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Weitere besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved by the features of the characterizing part of claim 1. Further particularly advantageous embodiments of the invention are disclosed in the subclaims.

Die Erfindung beruht im wesentlichen auf dem Gedanken, auf eine entsprechende abschlußkappenseitig angeordnete Dichtscheibe zu verzichten und durch eine an der Abdeckklappe befestigte elastische Dichtung zu ersetzen, welche im geschlossenen Zustand der Abdeckklappe mit einer Dichtlippe direkt an der Innenseite der aus einem Metall oder Kunststoff bestehenden Abschlußkappe anliegt. Hierdurch wird erreicht, daß Unebenheiten zwischen Abdeckklappe und Abschlußkappe ausgeglichen werden können. Außerdem ist die elastische Dichtung derart an der Abdeckklappe angeordnet, daß die Dichtung beim Einschieben des Schlüsselschaftes in den Schlüsselkanal von dem Schlüsselschaft -und damit auch von den in den Schaft eingefrästen Zähnen- nicht berührt wird.The invention is essentially based on the idea of dispensing with a corresponding sealing disc on the end cap side and replacing it with an elastic seal attached to the cover flap, which in the closed state of the cover flap with a sealing lip directly on the inside of the end cap made of a metal or plastic is present. This ensures that unevenness between the cover flap and end cap can be compensated. In addition, the elastic seal is arranged on the cover flap such that the seal is not touched by the key shaft — and thus also by the teeth milled into the shaft — when the key shaft is inserted into the key channel.

Eine derartige Anordnung der Dichtung an der Abdeckklappe kann vorteilhafterweise dadurch erfolgen, daß die Abdeckklappe auf der der Schlüsselkanalmündung zugewandten Seite zapfenförmig ausgebildet ist und im geschlossenen Zustand der Abdeckklappe in die Schlüsselkanalmündung teilweise hineinragt, wobei die elastische Dichtung auf der der Schlüsselkanalmündung abgewandten Seite des zapfenförmigen Teiles der Abdeckklappe befestigt ist.Such an arrangement of the seal on the cover flap can advantageously take place in that the cover flap is designed to be peg-shaped on the side facing the key channel mouth and partially protrudes into the key channel mouth when the cover flap is closed, with the elastic seal on the side of the peg-shaped part facing away from the key channel mouth the cover flap is attached.

Als Material für die elastische Dichtung haben sich sowohl Gummi als auch elastische Kunststoffe, insbesondere Polyurethan, bewährt. Die Abschlußkappe kann aus Metall oder Kunststoff gefertigt sein, wobei wegen des Fehlens der zusätzlichen Dichtscheibe die Wandstärke wesentlich dicker sein kann (z.B. 2-3 mm) als bei bekannten Schließzylindern (z.B. 0,7 mm).Both rubber and elastic plastics, in particular polyurethane, have proven themselves as the material for the elastic seal. The end cap can be made of metal or plastic, and because of the absence of the additional sealing washer, the wall thickness can be considerably thicker (for example 2-3 mm) than in known locking cylinders (for example 0.7 mm).

Bei der Abdeckklappe kann es sich um ein Metallgußteil, z.B. aus Aluminium, Magnesium oder Zink, handeln oder um ein Formteil aus Kunststoff.The cover flap can be a metal casting, e.g. made of aluminum, magnesium or zinc, or a molded part made of plastic.

Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus den folgenden anhand von Figuren erläuterten Ausführungsbeispielen. Es zeigen:

Further details and advantages of the invention result from the following exemplary embodiments explained with reference to figures. Show it:
Fig. 1
the cross section of the end face of a lock cylinder according to the invention without a key shaft inserted into the key channel and
Fig. 2
the cross section shown in Figure 1 after insertion of a key shaft.

In Fig. 1 ist mit 1 der kopfseitige Teil eines Schließzylinders bezeichnet, auf dem sich eine z.B. 2 mm starke Abschlußkappe 2 aus Stahl befindet. Die Abschlußkappe 2 weist zur Einführung eines Schlüsselschaftes 3 in den Schlüsselkanal 4 des Schließzylinders 1 eine Schlüsselkanalmündung 5 auf.In Fig. 1, 1 denotes the head-side part of a locking cylinder on which a e.g. 2 mm thick end cap 2 made of steel. The end cap 2 has a key channel mouth 5 for the insertion of a key shaft 3 into the key channel 4 of the locking cylinder 1.

Die Schlüsselkanalmündung 5 ist von dem Schließzylinderinnenraum 6 durch eine Abdeckklappe 7, bei der es sich beispielsweise um ein Kunststoff-Formteil handelt, verschlossen. Die Abdeckklappe 7 ist um eine Achse 8 in Richtung zu einer Seitenwand 9 des Schließzylinders 1 hin gegen den Druck einer Drehfeder 10 schwenkbar angeordnet.The key channel mouth 5 is closed by the lock cylinder interior 6 by a cover flap 7, which is, for example, a molded plastic part. The cover flap 7 is pivotable about an axis 8 in the direction of a side wall 9 of the lock cylinder 1 against the pressure of a torsion spring 10.

Die Abdeckklappe 7 ist auf der der Schlüsselkanalmündung 5 zugewandten Seite zapfenförmig mit leicht konischem Querschnittsverlauf ausgebildet, wobei das zapfenförmige Klappenteil 11 teilweise in die Schlüsselkanalmündung 5 hineinragt. Auf der der Schlüsselkanalmündung 5 abgewandten Seite des zapfenförmigen Klappenteiles 11 besitzt die Abdeckklappe eine umlaufende Nut 12, in die eine elastische Dichtung 13 montiert oder angespritzt ist.The cover flap 7 is cone-shaped on the side facing the key channel mouth 5 with a slightly conical cross-sectional shape, the pin-shaped flap part 11 partially protruding into the key channel mouth 5. The cover flap has on the side of the pin-shaped flap part 11 facing away from the key channel mouth 5 a circumferential groove 12, in which an elastic seal 13 is mounted or molded.

Die elastische Dichtung 13, bei der es sich um eine Profildichtung handelt, weist auf ihrer der umlaufenden Nut 12 abgewandten Seite eine Dichtlippe 14 auf, die an der Innenseite 15 der Abschlußkappe 2 anliegt. Die Dichtung 13 ist dabei gegenüber der Vorderfläche 16 des zapfenförmigen Klappenteiles 11 so weit in Richtung der Schließzylinderinnenseite 6 zurückversetzt, daß sie beim Einschieben des Schlüsselschaftes 3 von diesem nicht berührt wird.The elastic seal 13, which is a profile seal, has on its side facing away from the circumferential groove 12 a sealing lip 14 which bears against the inside 15 of the end cap 2. The seal 13 is in relation to the front surface 16 of the peg-shaped flap part 11 set back so far in the direction of the inside of the lock cylinder 6 that it is not touched by the key shaft 3 when it is inserted.

Im folgenden wird mit Hilfe der Fig.1 und 2 näher die Funktionsweise des erfindungsgemäßen Schließzylinders erläutert: Wird der Schlüsselschaft 3 durch die Schlüsselkanalmündung 5 hindurch in den Schließzylinder 1 gesteckt, so berührt die Vorderfläche 17 des Schlüsselschaftes 3 die Vorderfläche 16 der Abdeckklappe 7 und drückt diese gegen den Druck der Drehfeder 10 in den Schließzylinderinnenraum 6. Die Abdeckklappe 7 schwenkt dabei um die Drehachse 8 in Richtung auf die Seitenwand 9.The functioning of the locking cylinder according to the invention is explained in more detail below with the aid of FIGS. 1 and 2: If the key shaft 3 is inserted through the key channel opening 5 into the locking cylinder 1, the front surface 17 of the key shaft 3 touches the front surface 16 of the cover flap 7 and presses this against the pressure of the torsion spring 10 in the lock cylinder interior 6. The cover flap 7 pivots about the axis of rotation 8 in the direction of the side wall 9.

Bei einem weiteren Hineinschieben des Schlüsselschaftes 3 in den Schlüsselkanal 4 wirkt nicht mehr die gesamte Vorderfläche 17 des Schlüsselschaftes 3 auf die Vorderfläche 16 der Abdeckklappe 7, sondern lediglich ein relativ schmaler Randbereich. Bei noch weiterem Einschieben des Schlüsselschaftes 3 in den Schlüsselkanal 4 hinein, gleitet die Vorderfläche 17 des Schaftes 3 schließlich an der Abdeckklappe 7 vorbei. Diese liegt dann mit einem Teil ihrer Vorderfläche 16 an der entsprechenden Seitenwand 18 des Schaftes 3 an, ohne die Schaftbewegung zu behindern.When the key shaft 3 is pushed further into the key channel 4, the entire front surface 17 of the key shaft 3 no longer acts on the front surface 16 of the cover flap 7, but rather only a relatively narrow edge region. When the key shaft 3 is pushed even further into the key channel 4, the front surface 17 of the shaft 3 finally slides past the cover flap 7. This then lies with part of its front surface 16 on the corresponding side wall 18 of the shaft 3 without impeding the shaft movement.

Bei dem gesamten vorstehend beschriebenen Einführvorgang des Schlüsselschaftes 3 in den Schlüsselkanal 4 wurde aufgrund der gegenüber der Vorderfläche 16 der Abdeckklappe 7 zurückgesetzten elastischen Dichtung 13 diese von dem Schlüsselschaft 3 nicht berührt.In the entire insertion process described above Key shaft 3 in the key channel 4 was not touched by the key shaft 3 due to the elastic seal 13 which is set back in relation to the front surface 16 of the cover flap 7.

Die Erfindung ist selbstverständlich nicht auf das vorstehend beschriebene Ausführungsbeispiel beschränkt. So kann beispielsweise als Abdeckklappe 7 statt eines Kunststofformteiles auch ein Formteil aus Metall, wie Aluminium, Magnesium oder Zink, verwendet werden. Diese Formteile können beispielsweise mittels eines Druckgußverfahrens hergestellt werden.The invention is of course not limited to the embodiment described above. For example, instead of a plastic molded part, a molded part made of metal, such as aluminum, magnesium or zinc, can also be used as the cover flap 7. These molded parts can be produced, for example, by means of a die casting process.
