Die beiden U-Schenkel 2, 3 können unterschiedlich lang ausgebildet sein. An die äußeren Flachseiten des längeren U-Schenkel 2 ist ein Schloßkastenblech 5 angeordnet.The two U-legs 2, 3 can be of different lengths his. On the outer flat sides of the longer U-leg 2, a lock case plate 5 is arranged.

Das Schloßkastenblech 5 weist eine rechteckförmige Basiswandung 6 auf, die bezüglich ihrer Längserstreckung parallel zum U-schennkel 2 angeordnet ist und deren Breite in etwa der Breite des U-Schenkels 2 und dessen Orientierung entspricht. An den Seitenkanten der Basiswandung 6 sind zur Ausbildung eines quaderförmigen Schloßkastens 12 zwei Längsseitenwandungen 7 und zwei Stirnseitenwandungen 8 angebunden. The lock case plate 5 has a rectangular base wall 6, which are parallel to the U-leg with respect to their longitudinal extent 2 is arranged and its width is approximately the width of the U-leg 2 and its orientation corresponds. On the side edges the base wall 6 are to form a cuboid Lock case 12 two longitudinal side walls 7 and two End walls 8 tied.

Die Längsseitenwandungen 7 und die Stirnseitenwandungen 8 liegen an Stirnkanten 9 des freien U-Schenkels 2 an, die Stirnseitenwandung 8 liegt mit ihrer Stirnkante auf dem U-Schenkel 2 auf.The longitudinal side walls 7 and End walls 8 lie on front edges 9 of the free U-leg 2 on, the front side wall 8 lies with its front edge on the U-leg 2.

In dem Schloßkasten 12 ist in etwa in der Längsmitte von einer Längsseitenwandung 7 her eine in etwa halbkreiskogenförmige oder eliptischbogenförmige Aussparung 13 im U-Schenkel 2 und ein der Basis wandung 6 angeordnet, die Platz für die Aufnahme eines Türschließbolzens 14 schafft. Die Aussparung 13 erstreckt sich von der Längsseitenwandung 7, bis ungefähr zur Quermitte des Schloßbasisbleches 1 und des Schloßkastenbleches 5.In the lock case 12 is approximately in the longitudinal center of one Long side wall 7 forth an approximately semicircular or elliptical arch Recess 13 in the U-leg 2 and one of the base wall 6 arranged, the space for receiving a Door locking bolt 14 creates. The recess 13 extends from the longitudinal side wall 7 to approximately to the center the lock base plate 1 and the lock case plate 5.

Jeweils zur Stirnseite hin ist neben der Aussparung 13 in etwa in der Hälfte der Erstreckungstiefe der Aussparung 13 je ein hohlzylinderischer Achsbolzen 15 zwischen dem Schloßbasisblech 1 und dem Schloßkastenblech 5 angeordnet, wobei die Achsbolzen 15 das Schloßbasisblech 1 und das Schloßkastenblech 5 durchgreifen und vorzugsweise aneinander befestigen.In each case towards the end face is approximately in addition to the recess 13 in the Half of the depth of the recess 13 each hollow cylindrical axle bolt 15 between the lock base plate 1 and the lock case plate 5, the axle bolts 15 the lock base plate 1 and reach through the lock case plate 5 and preferably fasten to each other.

Durch die hohlzylindrischen Achsbolzen 15 können Schrauben durchgesteckt werden, mit denen das Schloß an einer Tür oder einem Türgestell angeschraubt werden kann.Screws can be inserted through the hollow cylindrical axle bolts 15 with which the lock on a door or a Door frame can be screwed on.

Auf den Achsbolzen 15 lagest benachbart zur Basiswandung 6 des Schloßkastenbleches 5 je eine Drehfalle 16 in einer Ebene fluchtend und voneinander gering beabstandet. Zwischen den Drehfallen 16 und dem Schloßbasisblech 1 ist je eine Drehfallenspiralfeder 17 auf den Achsbolzen 15 angeordnet, die sich jeweils einendig an Schloßkasten 12 und anderendig an einer Drehfalle 16, diese belastend absteiten.On the axle pin 15 were adjacent to the base wall 6 of the lock case plate 5 each has a rotary latch 16 in one plane aligned and slightly spaced from each other. Between the rotary latch 16 and the lock base plate 1 is ever a rotary latch coil spring 17 is arranged on the axle bolt 15, each of which ends at a lock case 12 and at the other end on a rotary latch 16, which stresses this.

Die Drehfallen 16 sind plattenförmige Elemente, beispielsweise Platten aus Stahl (Fig. 2). An jeder Drehfalle 16 ist je eine Riegelnase 19 mit einer Auskehlung 18 ausgebildet. In geöffneter Schloßstellung stehen die Nasen 19 über die Längsseitenwandung 7, in die die Aussparung 13 mündet, seitlich über die Längsseitenwandung 7 nach aüßen hinaus. Die Auskehlungen 18 der Riegelnasen 19 der Drehfallen 16 sind aufeinander zuweisend angeordnet. The rotary latches 16 are plate-shaped elements, for example Steel plates (Fig. 2). There is one on each catch 16 Bolt nose 19 formed with a groove 18. In open In the closed position, the lugs 19 stand over the longitudinal side wall 7, into which the recess 13 opens, laterally beyond the long side wall 7 to the outside. The fillets 18 of the locking lugs 19 of the rotary latches 16 are arranged facing one another.

Auf der den Auskehlungen 18 gegenüberliegenden Bereichen der Umfangskante der Drehfallen 16 sind Anschlagkanten 22 angeordnet, die an den die Aussparung 13 bergenzenden Kanten 23 der Längsseitenwandung 7 in geöffnete Stellung des Schlösses anliegen.On the areas of the Peripheral edge of the rotary latches 16 stop edges 22 are arranged, which bear against the edges 23 of the longitudinal side wall 7 that contain the recess 13 in the open position of the lock.

Die Drehfallenfedern 17 (Fig. 1) wirken, ähnlich wie es vom Stand der Technik bekannt ist, mit einem Federschenkel auf je einen Vorsprung 24 (Fig. 7a bis 9c), der in etwa diametral den Auskehlungen 18 gegenüberliegend an den Drehfallen 16 angeformt ist. Mit dem anderen Federschenkel stützen sie sich vorzugsweise an einer der Längsseitenwandungen 7 ab; die Federn 17 können über letztere Schenkel aber auch verbunden sein. Die Drehfallenfedern 17 haben das Bestreben, die Drehfallen 16 in geöffneter Stellung (Fig. 7a, Fig. 8a, Fig. 9a) zu halten und die aufeinanderweisenden Riegelnasen 19 auseinander zu drücken.The rotary latch springs 17 (Fig. 1) act similarly to it State of the art is known with a spring leg on each a projection 24 (Fig. 7a to 9c), which is approximately diametrically Grooves 18 formed on the rotary latch 16 opposite is. They prefer to support themselves with the other spring leg on one of the long side walls 7; the springs 17 can over the latter leg but also be connected. The rotary latch springs 17 endeavor to open the rotary latches 16 Hold position (Fig. 7a, Fig. 8a, Fig. 9a) and facing each other Press tabs 19 apart.

Benachbart zu jeder Auskehlung 18 auf der der Nase 19 gegenüberliegenden Seite der Auskehlung 18 sind zwei benachbarte Rastausnehmungen 25 in der Umfangskante der Drehfallen 16 angeordnet.Adjacent to each groove 18 on the nose 19 opposite Side of the groove 18 are two adjacent notches 25 arranged in the peripheral edge of the rotary latches 16.

Die Rastausnehmungen 25 sind angenähert V-förmig, jedoch hinterschnitten, ausgebildet, so daß jede Rastausnehmug 25 eine kurze, hinterschnittene Flanke 25a und eine lange schräge Flanke 25b aufweist (Fig. 7a). Die Gründe der Rastausnehmungen 25 sind abgerundet ausgeführt.The locking recesses 25 are approximately V-shaped, but undercut, trained so that each Rastausnehmug 25 a short, has undercut flank 25a and a long sloping flank 25b (Fig. 7a). The reasons for the recesses 25 are rounded executed.

Am und um das U-förmige Schloßbasisblech 1 herum ist ein im wesentlichen U-förmiger Entriegelungshebel 27 angeordnet (Fig. 1). Der Entriegelungshebel 27 weist zwei freie U-Schenkel 28, 29 sowie einen diese verbindenden U-Basissteg 30 auf.On and around the U-shaped lock base plate 1 is essentially one U-shaped unlocking lever 27 arranged (Fig. 1). The Release lever 27 has two free U-legs 28, 29 and a U base web 30 connecting them.

Der Basissteg 30 ist parallel zum U-Basissteg 4 des Schloßbasisblechs 1 angeordnet. Parallel zum freien U-Schenkel 2 des Schloßbasisblechs 1 erstreckt sich der Schenkel 28 bzw. Rastarm 28 des Hebels 27 in Richtung des Schloßkastens und durch eine Ausnehmung 31 (Fig. 3) in der den BasisSchenkel 4 zugewandten horizontalen Stirnseitenwandung 8 in den Schloßkasten 12 hinein.The base web 30 is parallel to the U base web 4 the lock base plate 1 arranged. Parallel to Free U-leg 2 of the lock base plate 1 extends Leg 28 or locking arm 28 of the lever 27 in the direction of the lock case and through a recess 31 (Fig. 3) in the base leg 4 facing horizontal end wall 8 in the lock case 12 in.

Das freie Ende des Schenkels bzw. Rastarmes 28 erstreckt sich bis auf die Höhe der Rastausnehmungen 25 der beiden Drehfallen (Fig. 8a bis 9c).The free end of the leg or latch arm 28 extends up to the height of the recesses 25 of the two rotary latches (Fig. 8a to 9c).

In Richtung zu den Drehfallen 16 ist ein angenähert rechteckiges Raststück 33 seitlich an dem freien Ende des Schenkels 28 angeformt.In the direction of the rotary latches 16 there is an approximately rectangular locking piece 33 on the side molded onto the free end of the leg 28.

Das Raststück 33 weist zwei Stirnkanten 34, 35 und drehfallenseitig, eine die Stirnkanten 34, 35 verbindende Längskante 36 auf (Fig. 9).The locking piece 33 has two end edges 34, 35 and on the rotary latch side, a longitudinal edge 36 connecting the end edges 34, 35 on (Fig. 9).

Die Längskante 36 des Raststückes 33 und die Stirnkanten 34, 35 weisen gemeinsame Ecken 37a, 37b auf.The longitudinal edge 36 of the locking piece 33 and the end edges 34, 35 have common corners 37a, 37b.

In die Längskante 36 ist eine Auskehlung 39 eingebracht, die in Richtung des freien Endes des Schenkels 28 verschoben ist, so daß die Kantenstücke 36a, 36b vom Grund der Auskehlung 39 zu den Ecken 37 hin unterschiedlich lang sind. Hierdurch werden je eine Rastnase 38a, 38b gebildet (Fig. 9).In the longitudinal edge 36, a groove 39 is introduced, which in Direction of the free end of the leg 28 is shifted so that the edge pieces 36a, 36b from the bottom of the groove 39 to the Corners 37 are of different lengths. This will be one Detent 38a, 38b formed (Fig. 9).

Die Ecken 37a, 37b sind abgerundet ausgeführt, wobei die Kanten 34 und 36a sowie 35 und 36b jeweils einen spitzen Winkel einschließen.The corners 37a, 37b are rounded, the edges 34 and 36a and 35 and 36b each form an acute angle.

Die Kante 36b verläuft darüber hinaus nicht geradlinig vom Grund der Auskehlung 39 zur Ecke 37b, sondern ist leicht gewölbt derart ausgeführt, daß sie vom Grund der Auskehlung 39 zunächst einen steileren Verlauf hat und zur Ecke 37b hin immer flacher wird.In addition, the edge 36b does not run in a straight line from the bottom the groove 39 to the corner 37b, but is slightly curved such stated that they start from the bottom of the groove 39 has a steeper course and is becoming flatter towards corner 37b becomes.

Die Kante 35 ist von der Ecke 37b her zum Schenkel 28 hin leicht hinterschnitten ausgeführt, so daß das Raststück 33 zu den Ecken 37a, b im Bereich der Kante 35 etwas breiter wird (Fig. 9).The edge 35 is slight from the corner 37b to the leg 28 undercut so that the locking piece 33 to the corners 37a, b becomes somewhat wider in the region of the edge 35 (FIG. 9).

In Sicherheitsraststellung des Schlosses, wenn die Rastnasen 38a, 38b sich in den in Drehrichtung jeweils ersten Rastausnehmungen 25 der Drehfallen 16 befinden, werden die Ecken 37a, 37b der Rastnasen 38a, 38b formschlüssig von den Rastausnehmungen 25 umfaßt, wobei die kurzen Flanken 25a der Rastausnehmungen 25 an den Kanten 36a, 36b auf und die langen Flanken 25b an den Stirnkanten 34, 35 anliegen.In the safety locking position of the lock when the locking lugs 38a, 38b in the respective first recesses in the direction of rotation 25 of the rotary latches 16 are the corners 37a, 37b of the locking lugs 38a, 38b in a form-fitting manner from the locking recesses 25 comprises, the short flanks 25a of the recesses 25 on the edges 36a, 36b and the long flanks 25b the front edges 34, 35 abut.

In vollständiger Schließposition, wenn die Rastnasen 38a, 38b sich in den in Drehrichtung jeweils zweiten Rastausnehmungen 25 befinden, liegen die Rastausnehmungen 25 nur an den Kanten 34, 35 an, indem eine Rastausnehmüng 25 mit ihrer Kante 25b auf der Stirnkante 34 aufliegt und die andere Rastausnehmung 25 mit ihrer Kante 25a auf der Stirnkante 35 aufliegt.In the fully closed position when the detents 38a, 38b each in the second locking recesses in the direction of rotation 25 are located, the recesses 25 are only on the edges 34, 35 by a locking recess 25 with its edge 25b rests on the front edge 34 and the other latching recess 25 rests with its edge 25a on the front edge 35.

Die Stirnkante 35 wirkt bei sich verbreiterndem Raststück 33 in vorteilhafter Weise in den entsprechend geformten bzw. hinterschnittenen Rastausnehmungen 25 hintergreifend, derart, daß, wenn die Stirnkante 35 aus der Rastausnehmung 25 hinausgeführt werden soll, auch der Widerstand der Drehfallenfeder 17, die hierbei gedehnt wird, überwunden werden muß.The front edge 35 acts when the locking piece 33 widens advantageously in the correspondingly shaped or undercut Engaging recesses 25 behind, such that, when the front edge 35 is led out of the recess 25 should also be the resistance of the rotary latch spring 17, which in this case is stretched, must be overcome.

Zwischen Raststück 33 und der den U-Basisstegen 4, 30 zugewandten Stirnseitenwandung 8 des Schloßkastens 12 ist der Hebel 27 bzw. dessen Schenkel 28 auf einem vorzugsweise hohlzylindrischen, horizontalen, das Schloßbasisblech 1 und Schloßkastenblech 5 durchgreifenden und verbindenden Zapfen 56 schwenkbar gelagert.Between locking piece 33 and the U-base webs 4, 30 facing The end wall 8 of the lock case 12 is the lever 27 or its leg 28 on a preferably hollow cylindrical, horizontal, the lock base plate 1 and lock case plate 5 penetrating and connecting pin 56 pivotable stored.

In Höhe und Seite zu diesem Zapfen 56 fluchtend ist an der Außenseite des U-Schenkels 3 des Schloßbasisbleches 1 ein zweiter Drehzapfen 57 (Fig. 2, 3) angeordnet, auf welchem der Hebel 27 mit seinem U-Schenkel bzw. Betätigungsarm oder -hebel 29 ebenfalls schwenkbar gelagert ist, wobei die Schwenkachse 58 der beiden Drehzapfen 56, 57 die Gleiche ist.In height and side to this pin 56 is aligned on the outside the U-leg 3 of the lock base plate 1 a second Pivot 57 (Fig. 2, 3) arranged on which the lever 27th with its U-leg or actuating arm or lever 29 likewise is pivotally mounted, the pivot axis 58 of the two pivots 56, 57 is the same.

Um den Drehzapfen 57 kann eine Spiralfeder 59 angeordnet sein, die so auf den Hebel 27 wirkt, daß das Raststück 33 auf die Drehfallen 16 zugedrückt wird und diese kontaktiert (Fig. 11). A spiral spring 59 can be arranged around the pivot pin 57 acts on the lever 27 that the locking piece 33 on the rotary latches 16 is pressed and contacted (Fig. 11).

Der U-Schenkel 29 erstreckt sich über den Drehzapfen 57 hinaus. Sein freies Ende ist als Ausgleichsgewicht 40 (Fig. 1) ausgebildet.The U-leg 29 extends beyond the pivot 57. Its free end is designed as a balance weight 40 (Fig. 1).

Der U-Basisschenkel 30 ist über den U-Schenkel 29 hinaus verlängert und als Öffnungsgriff 42 ausgebildet. Mit dem Öffnungsgriff 42 kann das Schloß vom Fahrzeuginneren her über den Schenkel 29 betätigt werden. Der Schenkel 29 übernimmt die Funktion eines Betätigungshebels. Der Kreuzungsbereich zwischen Schenkel 29, Basissteg 30 und Hebel 42 weist eine Bohrung 43 senkrecht zu der Erstreckungsrichtung des Schenkels 29 und des Hebels 42 auf.The U base leg 30 is extended beyond the U leg 29 and designed as an opening handle 42. With the opening handle 42 can the lock from the inside of the vehicle over the leg 29 are operated. The leg 29 takes over the function an operating lever. The area of intersection between the legs 29, base web 30 and lever 42 have a bore 43 perpendicular to them the direction of extension of the leg 29 and the lever 42.

Die Bohrung 43 dient der Aufnahme einer Stellschraube 45 (Fig. 11, 12), mit der das Spiel zwischen Hebel 27 und einem Betätigungselement, welches von der Türaußenseite betätigbar ist, einstellbar ist.The bore 43 serves to receive an adjusting screw 45 (FIG. 11, 12) with which the play between lever 27 and an actuating element, which can be operated from the outside of the door, is adjustable.

Die Stellschraube 45 ist von der den Drehfallen gegenüberliegenden Seite her in die Bohrung 43 eingedreht.The adjusting screw 45 is opposite to the rotary latches Screwed into the hole 43.

Auf einer Seite zum Betätigungselement hin steht die Stellschraube 45 mit einem flachen, rundlichen Kopf 60 über. Auf der glatten rundlichen Oberfläche 61 des Kopfes 60 liegt das Betätigungselement (nicht gezeigt), beispielsweise ein Türöffnungsdrücker vorzugsweise ohne Spiel auf. Das Spiel wird durch die Eindrehtiefe der Schraube 45 eingestellt.The set screw is on one side towards the actuating element 45 with a flat, rounded head 60 over. On the smooth actuating surface 61 of the head 60 is located (not shown), for example a door opener preferably without play. The game is played by Screw-in depth of screw 45 set.

Auf der glatten Oberfläche 61 des Kopfes 60 kann das Betätigungselement bei der Betätigung entlanggleiten. Auf der dem Kopf 60 gegenüberliegenden Seite 62 weist die Stellschraube 45 einen Kreuzschlitz 63 auf (Fig. 12).On the smooth surface 61 of the head 60, the actuator glide along when actuated. On the head 60 opposite side 62 has the adjusting screw 45 Phillips 63 on (Fig. 12).

Die Feder 59, welche auf den Hebel 27 wirkt, ist bei vorhandener Schraube 45 in Richtung des Kreuzungsbereichs zwischen Schenkel 29, Basissteg 30 und Hebel 42 verlängert. Auf der Höhe der Bohrung 43 ist die Feder 59 um etwa 90° abgebogen und erstreckt sich in Richtung zum Öffnungshebel 42 über die Bohrung 43 hinweg. The spring 59, which acts on the lever 27, is present Screw 45 in the direction of the crossover area between the legs 29, base bar 30 and lever 42 extended. At the level of the hole 43 the spring 59 is bent through approximately 90 ° and extends towards the opening lever 42 over the bore 43.

Der Federschenkel der Feder 59 ruht in einem der beiden, rechtwinklig zueinander orientierten, den Kreuzschlitz 63 bildenden Schlitze und verhindert so ein Verdrehen der Schraube 45, wodurch sich das Spiel zwischen Schraubenkopf 60 und Betätigungselement nicht verändert bzw. nicht durch unbeabsichtigtes Verdrehen der Schraube einstellt.The spring leg of the spring 59 rests in one of the two, at right angles oriented towards each other, forming the cross slot 63 Slots and thus prevents the screw 45 from rotating, thereby the game between screw head 60 and actuator not changed or not by unintentional twisting the screw.

Soll die Schraube 45 verdreht werden, muß zunächst die Feder 59 aus dem Kreuzschlitz 63 ausgehoben werden.If the screw 45 is to be rotated, the spring 59 must first can be excavated from the cross recess 63.

Zwischen der dem Raststück 33 abgewandten Längsseitenwandung 7 und dem freien Ende des U-Schenkels 28 kann eine Feder 44 (Fig. 8a, 8b, 8c) angeordnet sein, die das Raststück 33 gegen die Drehfallen 16 bzw. bei geöffnetem Schloß in die Rastausnehmungen 25 drückt.Between the longitudinal side wall facing away from the locking piece 33 7 and the free end of the U-leg 28, a spring 44th (Fig. 8a, 8b, 8c) can be arranged, the locking piece 33 against the rotary latch 16 or in the recesses when the lock is open 25 presses.

In geöffneter Stellung des Schlosses befinden sich die Rastausnehmungen 25 zwischen den Riegelnasen 19 der Drehfallen 16 und dem Raststück 33, wobei sich die Rastausnehmungen 25 der Drehfallen 16 gegenüberliegen. Wird die Tür geschlossen, so drückt der Türschließbolzen 14 gegen die Drehfallen 16 gegen den Druck der Drehfallenfedern 17. Hierdurch drehen sich die Drehfallen 16 gegenläufig um die hohlzylinderischen Achsbolzen 15, so daß die Verriegelungsnasen 19 aufeinander zu und in Türschließrichtung (Pfeil 55) gesehen hinter den Türschließbolzen gelangen.The locking recesses are in the open position of the lock 25 between the locking lugs 19 of the rotary latches 16 and the locking piece 33, the locking recesses 25 of the rotary latches 16 face each other. If the door is closed, press the door locking bolt 14 against the rotary latch 16 against the pressure of the rotary latch springs 17. This causes the rotary latches 16 to rotate in opposite directions around the hollow cylindrical axle bolts 15, so that the Locking lugs 19 towards each other and in the door closing direction (Arrow 55) seen behind the door locking bolt.

Durch die Drehbewegung gelangen je die ersten Rastausnehmungen 25 in den Bereich des unter Federdruck stehenden Raststückes 33, dessen Rastnasen 38a, 38b, sobald der Abstand zwischen den jeweiligen Rastausnehmungen 25 der beiden Drehfallen 16 groß genug ist, in die je erste Rastausnehmung 25 gelangen (Sicherheitsrast). Werden die Drehfallen 16 weiter gedreht, gelangen die Rastnasen 38a, 38b in die jeweils zweiten Rastausnehmungen 25 der Drehfallen 16. Die Drehfallen 16 befinden sich dann in vollständiger Schließposition (Fig. 7c, 8c, 9c), wobei der Türschließbolzen 14 von den Drehfallen 16 fest umgriffen ist.The first latching recesses come through the rotary movement 25 in the area of the locking piece 33 under spring pressure, whose locking lugs 38a, 38b, as soon as the distance between the respective Locking recesses 25 of the two rotary latches 16 are large enough into which the first latching recess 25 reaches (safety latch). If the rotary latches 16 are rotated further, the Locking lugs 38a, 38b in the respective second locking recesses 25 of the Rotary traps 16. The rotary traps 16 are then complete Closed position (Fig. 7c, 8c, 9c), the door locking bolt 14 is firmly gripped by the rotary latches 16.

Das Schloß wird hierdurch in geschlossener Stellung gehalten.The lock is hereby held in the closed position.

Wird der Öffnungsgriff 42 betätigt, so wird das Raststück 33 gegen den Druck der Feder 59 bzw. 44 aus den Rastausnehmungen 25 hinausgedrückt und die vorstehenden Rastnasen 38a, 38b gegen den Druck der Drehfallenfedern 17 aus den Rastausnehmungen 25 gedrückt. Ist das Raststück 33 mit seinen Rastnasen 38a, 38b ganz aus den Rastausnehmungen 25 hinausgelangt, schnappen die Drehfallen 16 unter dem Druck der Drehfallenfedern 17 aus ihrer Ausgangsposition in die geöffnete Stellung zurück. Der Türschließbolzen wird durch die Wandungen der Auskehlungen 18 aus dem Schloßkasten gedrückt.If the opening handle 42 is actuated, the locking piece 33 against the pressure of the spring 59 or 44 from the locking recesses 25 pushed out and the protruding locking lugs 38a, 38b against the Pressure of the rotary latch springs 17 pressed out of the locking recesses 25. Is the locking piece 33 with its locking lugs 38a, 38b entirely Get out of the recesses 25, the rotary latch snap 16 under the pressure of the rotary latch springs 17 from their starting position back to the open position. The door locking bolt is characterized by the walls of the grooves 18 the lock case.

Eine weitere vorteilhafte Ausführungsform des erfindungsgemäßen Fahrzeugtürschlosses ist mit einer Kindersicherung ausgestattet, die es ermöglicht, ein Öffnen des Schlosses von innen zu verhindern (Figuren 3, 4, 6). Hierfür ist der Entriegelungshebel 27 in zwei Teile 27a, 27b unterteilt, wobei der erste Teil 27a den in das Schloß hineinragende U-Schenkel 28 sowie den U-Basissteg 30 aufweist und der zweite Teil 27b den freien U-Schenkel 29 und den auf diesen wirkenden Öffnungsgriff 42 aufweist. Zwischen diesen beiden Teilen 27a, 27b des Entriegelungshebels 27 besteht im Bereich des Abzweiges vom U-Basissteg 30 zum U-Schenkel 29 und zum Betätigungsgriff 42 ein Spalt 46, durch den die beiden einstückig ausgeführten Teile räumlich getrennt sind.Another advantageous embodiment of the invention Vehicle door lock is equipped with a child lock, which makes it possible to prevent the lock from opening from the inside (Figures 3, 4, 6). For this, the release lever 27 in divided two parts 27a, 27b, the first part 27a the in the U-leg 28 protruding into the lock and the U-base web 30 has and the second part 27b the free U-leg 29 and has the opening handle 42 acting thereon. Between these two parts 27a, 27b of the unlocking lever 27 in the region of the branch from the U base web 30 to the U leg 29 and to the operating handle 42 a gap 46 through which the two parts made in one piece are spatially separated.

Am Betätigungshebel 42 ist in Betätigungs- bzw. Öffnungsrichtung (Pfeil 60) vor dem U-Basissteg 30 befindlich, den Spalt 46 überbrückend ein Mitnahmesteg 47 angeordnet.The actuation lever 42 is in the actuation or opening direction (Arrow 60) in front of the U-base web 30, bridging the gap 46 a carrier web 47 is arranged.

Wird der Öffnungsgriff 42 um das Schloß zu öffnen betätigt, wirkt der Mitnahmesteg 47 auf den U-Basissteg 30 und überträgt so die auf den Öffnungsgriff 42 wirkende Kraft auf den U-Basissteg 30, den U-Schenkel 28 und somit auch das Raststück 33. If the opening handle 42 is actuated to open the lock, the carrier bar 47 acts on the U base bar 30 and transmits so the force acting on the opening handle 42 on the U-base web 30, the U-leg 28 and thus also the locking piece 33.

Um eine Öffnung des Schlosses vom Fahrzeuginneren her, durch Betätigen des Öffnungshebels 42 zu verhindern, ist am freien U-Schenkel 3 des Schloßbasisblechs 1 ein verschwenkbarer Sicherungshebel 48 angeordnet. Der Sicherungshebel 48 ist in Öffnungsrichtung gesehen hinter den freien U-Schenkeln 29 des Entriegelungshebels 27 angeordnet und wirkt auf diesen in einem unmittelbar zum Spalt 46 benachbarten Bereich.To open the lock from inside the vehicle To prevent actuation of the opening lever 42 is on the free U-leg 3 of the lock base plate 1 a pivotable locking lever 48 arranged. The locking lever 48 is in the opening direction seen behind the free U-legs 29 of the Unlocking lever 27 is arranged and acts on it in one directly adjacent to the gap 46.

Der Sicherungshebel 48 weist einen Sicherungsarm 49 und einen sich daran anschließenden Betätigungsarm 50 auf, zwischen denen senkrecht zur gemeinsamen Längserstreckung dieser beiden die Schwenkachse 51 verläuft, um die der Sicherungshebel 48 mittels eines Zapfens 52 verschwenkbar am U-Schenkel 3 angeordnet ist. In der Sicherungsstellung wirkt der Sicherungsarm 49 mit einer Stirnfläche 52 auf den U-Schenkel 29 und sperrt dessen Beweglichkeit.The locking lever 48 has a locking arm 49 and one adjoining actuating arm 50, between which perpendicular to the common longitudinal extension of these two Pivot axis 51 extends around which the securing lever 48 is by means of of a pin 52 is arranged pivotably on the U-leg 3. In the secured position, the securing arm 49 acts with a End face 52 on the U-leg 29 and blocks its mobility.

Vorzugsweise verrastet der Sicherungshebel 48 in der sichernden und in der entsicherten Endposition, um ein ungewolltes Sichern oder Entsichern zu verhindern.The securing lever 48 preferably latches in the securing and in the unlocked end position to prevent unwanted securing or to prevent unlocking.

Bei zweigeteiltem Entriegelungshebel 27 muß auch auf den U-Schenkel 28 und damit das Raststück 33 eine Feder in Richtung der Raststellung wirken, da die Feder 39, die auf den U-Schenkel 29 wirkt, aufgrund der konstruktiven Trennung zwischen U-Schenkel 29 und U-Basissteg 30 nicht mehr gleichzeitig auf den U-Schenkel 28 wirkt.When the release lever 27 is in two parts, it must also be on the U-leg 28 and thus the locking piece 33 a spring in the direction the rest position act as the spring 39, which on the U-leg 29 acts due to the structural separation between the U-legs 29 and U base web 30 no longer simultaneously on the U leg 28 acts.

Die Feder 44, die auf das Raststück wirkt, kann wie bereits ausgeführt auf der den Drehfallen 16 abgewandten Seite des U-Schenkels 28 zwischen dem Schenkel 28 und der vertikalen Seitenwandung 7 des Schloßkastenblechs 5 in Form einer Schraubendruckfeder 44 (Figuren 8a, 8b, 8c) oder beispielsweise auch um den Drehzapfen 57 des Schenkels 28 angeordnet sein, wobei im letzteren Fall sich ein Federschenkel an der vertikalen Seitenwandung 7 des Schloßkastenbleches 5 und der in entgegengesetzter Richtung wirkender Federschenkel an der den Drehfallen 16 abgewandten Seite des Schenkels 28 abstützt (Figur 9b).The spring 44, which acts on the locking piece, can as before executed on the side of the U-leg facing away from the rotary latches 16 28 between the leg 28 and the vertical side wall 7 of the lock case plate 5 in the form of a helical compression spring 44 (Figures 8a, 8b, 8c) or, for example, around the Pivots 57 of the leg 28 may be arranged, the latter in the latter Fall a spring leg on the vertical side wall 7 of the lock case plate 5 and in the opposite direction acting spring leg on the rotary latch 16 facing away Side of the leg 28 is supported (Figure 9b).

Bei einem erfindungsgemäßen Fahrzeugtürschloß ist von Vorteil, daß der Entriegelungshebel einstückig ausgeführt ist. Hierdurch wird zum einen der Fertigungsaufwand erheblich verringert, zum anderen muß bei der Montage nicht ein mehrteiliges Hebelsystem mit Stellschrauben aufeinander eingestellt und nach mehrmaligen Betätigen nachjustiert werden. Ein weiterer Vorteil ist, daß der Schloßkasten und die Teile, an denen das Hebelsystem angelenkt ist, durch das U-förmige Schloßbasisblech eine bauliche Einheit bilden und so ebenfalls vormontiert und danach nicht weiter justiert werden müssen. Das Schloß kann so, ohne daß es an die üblichen Trägerbauteile montiert werden muß, direkt an bzw. in der Tür eingebaut werden.In a vehicle door lock according to the invention, it is advantageous that the unlocking lever is made in one piece. Hereby on the one hand, the manufacturing effort is significantly reduced others do not need a multi-part lever system during assembly adjusted to each other with adjusting screws and after repeated Press to be readjusted. Another advantage is that the Lock case and the parts to which the lever system is hinged is a structural unit thanks to the U-shaped lock base plate form and so also pre-assembled and then no further have to be adjusted. The lock can be so without it usual support components must be mounted directly on or in the door.

Darüber hinaus wird durch die Anordnung des Ausgleichgewichts auf der im Vergleich zum Stand der Technik gegenüberliegenden Hebelseite verhindert, daß das Ausgleichsgewicht bei Stoß oder Schlag das Schloß durch sein Beharrungsvermögen öffnet, im Gegenteil die Verriegelung wird sogar gesichert.In addition, the arrangement of the balance weight on the lever side opposite to the state of the art prevents the balancing weight in the event of impact or impact Lock opened by his perseverance, on the contrary Locking is even secured.

Durch die Hinterschneidung der Rastkanten, die das Raststück nach oben und unten verbreitert, sowie die korrespondierenden Einwölbungen bzw. Hinterschneidungen der Rastausnehmungen und die dadurch hintergreifende Wirkung wird die Rastsicherheit erheblich erhöht, auch deshalb, weil die Rastkanten und die Flanke des Raststücks 33 auf einer viel größeren Fläche der Rastausnehmungen aufliegen als im Stand der Technik bekannt und beim Öffnen zusätzlich die Drehfallenfedern gedehnt werden müssen.By undercut the locking edges that the locking piece widened up and down, as well as the corresponding ones Arches or undercuts of the recesses and the resulting effect becomes rest safety significantly increased, also because the locking edges and the flank of the locking piece 33 on a much larger area of the locking recesses lie as known in the prior art and when opening the torsion latch springs must also be stretched.

Durch die U-förmige Ausführung des Schloßbasisbleches und die Anordnung des Entriegelungshebels an diesem Schloßbasisblech und nicht an einem Türblech kann das Schloß komplett funktionstüchtig vormontiert am Türblech oder -rahmen angeordnet werden, was den Montageaufwand erheblich vermindert.Due to the U-shaped design of the lock base plate and the Arrangement of the release lever on this lock base plate and the lock cannot be fully functional on a door panel pre-assembled on the door panel or frame, what the assembly effort significantly reduced.

Durch das Vorsehen einer Kindersicherung schließlich erhöht sich die Sicherheit des Fahrzeugtürschlosses im erheblichen Maß.Finally, by providing a child lock increases the security of the vehicle door lock to a considerable extent.
