Description

The invention relates to a vehicle door lock with a rotary latch assembly for locking and closing doors of motor vehicles, especially doors of agricultural machinery, such as tractors.

Such a door lock is for example from the DE 196 53 169 A1 known ( Figure 26 ). This vehicle door lock has a flat block-shaped lock case 200 with a horizontal box bottom wall 201, a parallel box cover (not shown), two horizontal and box bottom wall 201 vertical Kastenquerwandungen 202,203 and two vertically oriented Kastenlängswandungen 204,205, which is arranged on a vehicle door, not shown, of a vehicle and includes the components necessary for interlocking closing. Towards a locking pin 206 projecting horizontally on the doorpost, the box bottom wall 201 and the box longitudinal wall 204 have a recess 207 in which the closing bolt 206 is received in the closed state of the door.

Adjacent to the recess 207 above and below this and aligned one above the other, and arranged at a small distance from each other, the lock case 200 has one, about a rotary pivot pin 208 pivotable rotary latch 209. The rotary latches 209 are plate-shaped elements, which outwardly, in the direction of the locking pin 206 on the lock case 200 protruding lugs 210 have. The lugs 210 each have a groove 211 in a circumferential wall 212 of the rotary latch 209. The grooves 211 of the lugs 210 face each other.

In addition, two rotary coil springs 213 are provided, of which only one is shown, which is about the rotary pivot pins 208 are arranged around. These rotary coil springs 213 are each supported by a spring leg on a respective projection 214, which is formed approximately diametrically opposite the grooves 211 on the rotary latches 209 and with a second spring leg on the inside of the box longitudinal wall 204 (not shown) and have an endeavor, to keep the rotary latches 209 in an open position, so to press the facing lugs 210 apart.

Furthermore, two adjacent, substantially V-shaped recesses 215,216 are introduced into the peripheral walls 212 of the rotary traps 209, wherein the recesses 215,216 both rotary traps 209 are opposite in the open lock position.

In which the recess 207 opposite region of the lock case 200, between rotary latches 209 and the box longitudinal wall 205, a locking lever or a pawl 217 is arranged. The locking lever 217 is pivotable about a locking lever pivot pin 218, which is arranged horizontally in one of the box longitudinal wall 205 and the box transverse wall 202 adjacent corner region of the lock case 200. At one end of the latching lever 217, a locking piece 219 zuweisendes latching piece 219 is formed, the two end edges 220,221 and rotary latch side, the front edges 220,221 connecting longitudinal edge 222, wherein in the longitudinal edge 222 a Längskantenauskehlung 223 is introduced, so that each one lever latch 224,225 is formed. With the lever detents 224,225 the remainder piece 219 is in the open position initially on the peripheral wall 212 of the rotary traps 209 below. Pressure of one, z. B. spiral, detent lever spring (not shown) to, for example, is arranged around the locking lever pivot 218 and is supported with its locking lever spring legs on the box longitudinal wall 205 and on a provided at the free end of the locking lever 217 lever pin 226.

If a vehicle door is closed, the horizontal arranged on the door post locking bolt 206 enters the region of the grooves 211 of the rotary latches 209. By the pressure of the locking pin 206 on the rotary latches 209 these are against the pressure of the rotary latch springs 213 to the rotary lathes 208 pivoted in opposite directions of rotation. Due to the rotational movement, the lugs 210 reach behind the locking bolt 206 and surround it. In the closed position, the locking pin 206 is between the two rotary traps 209 in the region of the grooves 211. By pivoting the rotary latches 209 first reach the first V-shaped recesses 215 in the region of the locking piece 219, wherein due to the pressure of the detent lever spring lever lugs 224,225 in snap in the first recesses 215. In this so-called safety catch the lock is not completely closed, but can not be opened due to the blocking effect of the locking lever 217. Upon further pivoting of the rotary latches 209, the locking piece 219 reaches the lever detents 224,225 in each case a second recess 216 of the rotary traps 209 and snaps there. The rotary traps 209 are now based on the flanks of the recesses 216 on each flank of the lever lugs 224,225 of the locking piece 219 and are held against the pressure of the rotary latch springs 213 in the closed position.

If the vehicle door lock and thus the door are opened, a lever system (not shown), which is located in the door, operated. This lever system has a U-shaped lever which acts, for example, on the lever pin 226 of the locking lever 217 or integral with the locking lever 217 and this pushes against the pressure of the locking lever spring and the rotary latch springs 213 from the recesses 215 or 216. Have the lever latching noses 224, 225 leave the recesses 215 and 216, snap the rotary traps 209 under the pressure of the rotary latch springs 213 in their starting position, so the open lock position, back. The locking pin 206 is moved out of the lock case 200 by the flanks of the flutes 211.

This vehicle lock has proven itself. However, the vehicle doors, especially in agricultural vehicles, more and more made of glass and tends to get bigger and heavier, so that in these doors partially weighs 70-80 kg on the locks. As a result, the vehicle locks are becoming increasingly robust and larger must, due to the size and the necessary triggering forces to open and close the vehicle locks increase. Furthermore, the geometry of the locking lugs of the two rotary latches and the geometry of the locking lever is relatively expensive to design and manufacture, since everything must be precisely matched and the locking lugs have a different spatial shape due to the pivoting movement of the locking lever.

The problem with such heavy vehicle doors are also the high forces acting on the rotary latches and the locking bolt when closing and opening the vehicle doors when the vehicle door is not exactly centered hung, and thus the locking pin is not exactly centered in the groove and the rotary traps introduced but slides along one side of the groove and the vehicle door is centered with its high weight only during the closing process. If excessive forces act on the locking pin, this can lead to bending or even breaking of the locking bolt. In any case, the life of such a door lock is significantly reduced by these high forces.

The object of the invention is to provide a vehicle door lock that can be inexpensively and easily manufactured, is easy to assemble and in which the opening forces required to open and close are as small as possible. Another object of the invention is to provide a vehicle door lock in which the forces acting on the latch bolt and the rotary latch when the vehicle door is hinged open when opening and closing are significantly reduced.

These objects are achieved with the features of claims 1 and 22. Advantageous developments of the invention are characterized in the respective subclaims.

The door lock 1 according to the invention has a parallelepiped lock case 2 for receiving the lock mechanism with a flat bottom plate or rear wall 3, one of the bottom plate 3 opposite and parallel to this, plate-shaped cover or a front wall 4, two mutually parallel and vertical to the bottom plate 3 longitudinal walls. 5 , 6 and two mutually parallel and perpendicular to the longitudinal walls 5,6 transverse walls 7,8 on ( Fig.1-11 ).

In the lock case 2 is a continuously through the bottom plate 3, the cover 4 and the longitudinal wall 6 extending groove-shaped locking pin recess 61 is introduced, which creates space for receiving a door lock pin 18, which will be discussed in more detail below. The locking pin recess 61 is formed symmetrically to a transverse center plane 15 of the door lock 1 and extends along the transverse center plane 15 and parallel to the cover 4 viewed from the longitudinal wall 6 in the bottom plate 3 and the lid 4 and opens into a suitably round, preferably circular, recess bottom 62. In particular, the locking pin recess 61 in a view perpendicular to the cover 4 on a course that resembles the outline of a bell. The recess bottom 62 preferably extends to less than half the extent of the cover 4 and the bottom plate 3 in the direction of the transverse center plane 15 in the lid 4 and the bottom plate 3 into it.

The locking pin 18 is usually connected at one end to a plate-shaped mounting plate 107 ( Fig.19-22 ), preferably screwed, wherein the mounting plate 107 extends perpendicular to a locking pin axis 108. The mounting plate 107 is used for fastening, in particular screwing, the locking bolt 18 to the vehicle body 109th

Within the lock case 2, two rotary traps or rotary parts 9,10 are arranged, which are rotatably mounted on a respective, preferably hollow cylindrical, rotary latch bearing pin 12. The two rotary latch bearing bolts 12 are suitably fixedly connected to the bottom plate 3 and each have a Drehfallenlagerungsbolzenachse 13, which is perpendicular to the bottom plate 3. In addition, the two rotary latch bearing bolts 12 are arranged in the vicinity of the locking pin recess 61 having longitudinal wall 6 and symmetrically with respect to the transverse center plane 15 of the door lock 1 spaced from each other and dimensioned such that they pass through the lid 4 and fasten cover 4 and bottom plate 3 together. For example, screws could be pushed through the hollow cylindrical rotary latch bearing bolts 12, with which the lock 1 can be screwed to a door or a door frame (not shown).

The mounted on the rotary latch bearing pin 12 rotary trays 9,10 are plate-shaped elements, such as plates made of steel, which extend parallel to the bottom plate 3 and slightly spaced from this and have an identical spatial shape. In addition, the rotary traps 9,10 are arranged symmetrically to the transverse center plane 15 and formed. At each rotary latch 9,10 each a locking lug 16 is formed with a groove 17. The grooves 17 of the two rotary trays 9,10 are arranged facing each other and serve to accommodate the perpendicular to the bottom plate 3 extending and cylindrically shaped locking bolt 18, which will be discussed in more detail below. In an open lock position ( Fig.1 ) pass through the locking lugs 16 a in the locking bolt recess 61 having longitudinal wall 6 provided, perpendicular to the transverse center plane 15 extending slot 19 (FIG. Figure 7 . 11 ) and project laterally beyond the longitudinal wall 6. The slot 19 is also formed symmetrically to the transverse center plane 15 and extends parallel to the bottom plate 4 and seen from this approximately more than the amount of thickness of the two rotary trays 9,10 in the longitudinal wall 6 inside. The slot 19 also has, preferably perpendicular to the bottom plate 3 aligned, slot edge 19 a ( fig.11 ), which serve as a stop edge for each one of the respective groove 17 opposite nose rear wall 63, which will be explained later.

Furthermore, a circumferential wall 20 of the rotary latches 9, 10 has two adjacent first and second rotary latch latches 21, 22, which are arranged substantially opposite to the locking lugs 16. The two rotary latch lugs 21,22 each have a short, steeper edge 21a, 22a and a long, flatter edge 21b, 22b, wherein seen against a later closing direction of rotation 58 of the two rotary traps 9,10 each seen the short, steeper flanks 21a, 22a long, flatter edges 21b, 22b are arranged downstream.

Between the two rotary latch lugs 21,22 also a first, suitably V-shaped, recess 23 is formed, which is formed undercut due to the design of the two flanks 21a, 22b. A second, likewise expediently V-shaped, Drehfalleniastausnehmung 24 is formed by the short edge 22a of the second rotary latch lug 22 and adjoining the rotary latch lug 22 peripheral wall 20. In this case, the short edge 22a and the peripheral wall 20 preferably close to each other approximately at right angles. The reasons of the two Drehfallenrastausnehmungen 23,24 are preferably carried out rounded.

In addition, a projection 26 is provided in the peripheral wall 20, which is expediently arranged approximately opposite to the groove 17. The projections 26 serve to support rotary torsion springs or rotary coil springs 27 which are arranged around the rotary latch bearing bolts 12 and are supported by a first spring leg 27a on the projections 26 and with a second spring leg 27a on a longitudinal inner wall 28 of the longitudinal wall 6. The rotary latch springs 27 have the tendency, the rotary trays 9,10 in the open position ( Fig.1 ), so to press the mutually facing locking lugs 16 apart.

For actuating the two rotary latches 9, 10, the door lock 1 according to the invention has two latching levers or pawls 29, 30, which hold the rotary latches 9, 10 in a closed position (FIG. Figure 3 ) or a pre-locked position ( Fig.2 ) or release the two rotary latches 9, 10 ( Fig.1 . 5 ). The two pawls 29,30 are also plate-shaped, for example made of steel, and formed parallel to the bottom plate 3 extending and also have a substantially elongated and identical spatial form, wherein one end each a latch actuating portion 31 and the other end a storage portion 32 is provided. The storage section 32 in each case has a through hole 33, with which the pawls 29,30 are rotatably mounted on, preferably hollow cylindrical, pawl bearing bolts 34. The two pawl mounting bolts 34 are expediently also firmly connected to the bottom plate 3 and each have a pawl bearing pin axis 35 which is perpendicular to the bottom plate 3. In addition, the two pawl mounting bolts 34 in each of the transverse walls 7,8 and the longitudinal wall 5 formed corner areas symmetrically with respect to the transverse center plane 15 of the door lock 1 spaced from each other, so that the pawls are designed and arranged symmetrically 29 to symmetry to the transverse center plane 15 ,

The latch support bolts 34 are also sized so that they pass through the lid 4 and fasten cover 4 and bottom plate 3 together. By the hollow-cylindrical latch mounting bolts 34 in turn screws can be pushed through, with which the lock can be screwed to a door or a door frame (not shown).

The pawl actuating portion 31 of the two pawls 29,30 each has an integrally formed latching lug 36 which is formed to the rotary trays 9,10 indicative and formed substantially in the manner of a sawtooth facing the bearing portion 32 short, steep and preferably rectilinear ratchet nose 37 and a longer and less steep latch catch nose flank 25. The longer ratchet lug flank 25 is also rounded, so that it is flattened towards the short, steep latch catch nose flank 37.

In addition, the pawls 29,30 are arranged spring-loaded so that their oppositely disposed latch actuating portions 31 are pressed in the direction of the catch 9,10 or against it. For this purpose, for example, in each case a pawl torsion spring 14 is provided, which are arranged around the latch bearing pins 34 around and with a spring leg 14a on a longitudinal inner wall 11 of the longitudinal wall 5 and with the support other spring legs 14b on the pawls 29,30 itself ( Figure 3 ). Alternatively, a compression spring is provided in each case, which is also supported on the inner wall 11 of the longitudinal wall 5 and on the pawls 29,30 itself, for example in the region of the pawl actuating portion 31 (not shown).

At the actuation portion end of the pawls 29,28 an actuating or support projection 40 is provided in each case, which also extends in the direction of the rotary traps 9,10. This actuating projection 40 serves as a support for an actuating lever 38 with which the pawls 29,30 are rotated about the latch bearing pins 34.

This actuating lever 38 is also a preferably plate-shaped element whose mutually parallel lever side walls 39a, 39b are perpendicular to the bottom plate 3 of the lock case 2. In addition, the operating lever 38 consists essentially of a handle portion 41 having a substantially elongated course, and a one-piece molded to the handle portion 41 lever actuating portion 42. The handle portion 41 is used for gripping and operating or pivoting of the operating lever 38 by an operator, what will be discussed in more detail below, and is expediently ergonomically designed.

The lever actuation section 42 has an actuating nose 43 adjoining the handle part 41 in an extension and a contact or stop nose 44 which adjoins the actuating nose 43 substantially at right angles in the transition region from the handle part 41 to the lever actuating part 42.

Furthermore, the actuating lug 43 has an actuating end face 68, which merges into the actuating surface 66 via an actuating edge 69.

The handle part 41 facing away from the end of the actuating lug 43 is also preferably slightly widened with a trapezoidal cross-section educated ( Fig.1-3 . 5 . 11 ), so that the side walls 39a, 39b are no longer parallel to each other in this area.

Furthermore, in the area of the lever actuating section 42, a continuous lever mounting bore 48 is provided, in which a lever bearing pin 49 or the like, preferably having a collar, is arranged with a lever mounting pin axis 50 which is perpendicular to the lever side walls 39a, 39b. By means of the lever support pin 49, the actuating lever 38 is rotatably connected to the lid 4 of the lock case 2. For this purpose, two mutually parallel tabs 52 are integrally formed on a lid outer wall 51, which are aligned perpendicular to the cover 4 and parallel to the transverse walls 7,8 and each having a cylindrical, continuous lever mounting recess 53. In addition, the tabs 52 are arranged symmetrically to the transverse center plane 15. In the lever support recesses 53, the lever support recess axes 54 extend parallel to the cover 4 and the longitudinal walls 5,6, the lever support pin 49 is arranged. In this case, facing Lappeninnwandungen 55 expediently by the same amount as the lever side walls 39a, 39b spaced from each other, so that the actuating lever 38 is disposed between the lobes 52 and slidably against this. In addition, preferably a torsion spring or the like is provided (not shown), which presses the actuating lever 38 with its stop surface 67 against the lid outer side 51 and / or a cover-side outer edge of the longitudinal wall 5 ( Figure 7 ).

Furthermore, the cover 4 is recessed between the opposing lobes 52, so that a passage opening 60 (FIG. Figure 7 ) is formed, which is dimensioned such that the actuating lug 36 of the actuating lever 38 engages through and the actuating lever 38 can perform its pivotal movement unhindered.

According to a further embodiment of the invention ( Fig.12-18 ), a two-part operating lever 38a is provided. The operating lever 38 a consists of a handle lever 70 for gripping and actuating the door lock 1 from the vehicle interior side and from a lever lever 71 for actuating the door lock 1 from the outside by means of a suitable actuating mechanism, for example by a known push button (not shown).

In addition, the trigger lever 71 is arranged and dimensioned such that the driving and abutment surface 97 of the trigger lever 71 rests against the stepped bottom 87 of the driving and stop step shoulder 100 (not shown). And the actuating surface 66a of the trigger lever 71 rests on the rounded support projections 40 of the pawls 29,30. As a result, and preferably by a further, not shown torsion spring is also the lever lever 71st pressed with its Leückhebelanschlagfläche 67a against the lid outer side 51 and / or a cover-side outer edge of the longitudinal wall 5. In this case, the pressure surface 95 of the trigger lever 71 is expediently not arranged between the fork arms 75, but protrudes backwards therefrom, since the distance from the lever lever front side 90 to the lever lever rear side 91 in the region of the pressure surface 95 is greater than the distance between a Gabelarmvorderseite 102 to Gabelannrückseite 78th In addition, the fork arm front sides 102 are formed and arranged to be aligned in a direction perpendicular to the fork inner surfaces 76 of the printer lever front 90.

• In einer geöffneten Stellung des Türschlosses 1 befindet sich der Schließbolzen 18 außerhalb des Schlosskastens 2 zwischen den Auskehlungen 17 der beiden Drehfallen 9,10. Die Riegelnasen 16 durchreifen den Schlitz 19 und werden durch die Kraft der Drehfallendrehfedern 27 mit ihren Riegelnasenrückwandungen 63 gegen die als Anschlag dienenden und zur Bodenplatte 3 senkrechten Schlitzkanten 19a gedrückt. Des weiteren liegen die Sperrklinken 29,30 unter dem Druck der Klinkendrehfedern 14 mit ihren flachen Klinkenrastnasenflanken 25 an den langen, flacheren Flanken 21b der ersten Rastausnehmungen 21 an.

In the following, the operation and operation of the door lock 1 according to the invention is first explained in more detail with the one-piece operating lever 38:

• In an open position of the door lock 1, the locking pin 18 is outside the lock case 2 between the grooves 17 of the two rotary trays 9,10. The locking lugs 16 reach through the slot 19 and are pressed by the force of the rotary lobe torsion springs 27 with their locking lug rear walls 63 against the slot edges 19a serving as a stop and perpendicular to the base plate 3. Furthermore, the pawls 29,30 are under the pressure of the pawl torsion springs 14 with their flat latch ratchet edges 25 on the long, flatter edges 21b of the first recesses 21 at. The actuating lever 38 is in the open position of the door lock 1 according to the invention spring-loaded with its stop surface 67 on the lid outer side 51 and / or the cover-side outer edge of the longitudinal wall 5 (Fig. Figure 7 ) on and with its actuating surface 66 on the rounded support projections 40 of the pawls 29,30 on.

If the door is closed, the locking pin 18 pushes against a door closing direction (arrow 57) against Auskhlungswandugen 56 of the rotary trays 9,10 and the rotary traps 9,10 are against the pressure of the rotary latch springs 27 and partially the pawl springs 14 in the closing direction 58 in opposite directions around the hollow cylindrical Rotary latch bearing pin 12 is pivoted so that the locking lugs 16 are moved toward each other and partially enclose the locking pin 18, wherein the locking lugs 16 then with the locking pin 18 partially within the locking pin recess 61 of the lock case 2 ( Fig.2 ). By the rotational movement also get ever the first recesses 23 in the range of spring-loaded latch detent nose 36, which, as soon as the distance between the respective first recesses 23 of the two rotary latches 9,10 is large enough, enter the first locking recess 23 and there engage due to the spring pressure of the pawl torsion springs 14 (safety catch). In this position, the steep, short Rinkenrastnasenflanken 37 are on the short, undercut flanks 21a of the first rotary detent lugs 21, in particular form-fitting, so that the two rotary latches are locked 9,10 and not by the force of the rotary torsion springs 27 opposite to the closing direction of rotation 58th can be turned. In this case, the locking lugs 16 are arranged so far turned on each other that the locking pin 18 can no longer escape from the area between the grooves 17 and the door lock 1 is movable only by a certain amount in the door closing direction 57. The actuating lever 38 remains spring loaded in its previous position. Since the pawls 29,30 are spaced somewhat further from the rotary trays 9,10 than in the open position of the door lock 1, the actuating lever 38 is no longer with its actuating surface 66 on the support projections 40 on.

If the rotary latches 9,10 further rotated by the pressure of the locking pin 18 on the Auskehlungswandungen 56 in the closing direction 58, slide the flat Rinkenrastnasenflanken 25 along the flat, long edges 22b of the second Drehfallenrastnasen 21 along until the pawl latching lugs 36 in the second locking recesses 24th the rotary latches reach 9,10 and there latch due to the spring force of the pawl springs 14. The rotary traps 9,10 are then in the fully closed position ( Fig. 3 . 4 ), wherein the door lock bolt 18 is arranged in a form-fitting manner in the grooves 17 and is thus firmly gripped by the rotary latches 9, 10. In this position, the steep, short Rinkenrastnasenflanken 37 are on the short, undercut flanks 22a of the second Drehfallenrastnasen 22, in particular a form-fitting, so that the two rotary latches 9,10 are again locked and no longer by the force of Rotary torsion springs 27 opposite to the closing direction of rotation 58 can be rotated. As a result, the lock 1 is held in the closed position. The actuating lever 38 is in the closed position expediently again with its actuating surface 66 on the support projections 40.

To open the door lock 1 according to the invention from the pre-latched safety catch ( Fig.2 ) or from the closed position ( Figure 3 . 4 ), the actuating lever 38 is actuated by being pivoted, for example, against the force of the spring, not shown, in the lever rotation direction 64 about the lever support pin 49, so that the handle portion 41 in the direction of the rotary latches 9,10 and the lever actuating portion 42 of the rotary traps 9, 10 is moved away. This is done for example from the interior of a vehicle by pulling on the handle 41 of the one-piece operating lever 38 or from the outside in a conventional manner by pressing a push button, which is in operative connection with the actuating lever 38 and this pivoted (not shown). The support projections 40 on the adjacent actuating surfaces 66, or due to the rotation of the operating lever 38 via the actuating edge 69, positively entrained by the operating lugs 43 of the lever actuating portion 42 and thereby the pawls 29,30 far against the pressure of the pawl torsion springs 14 and, due the undercut execution of Drehfallenrastnasen 21,22 against aden pressure of the rotary latch springs 27 to the latch bearing pins 34 is rotated until the latch pawls 36 are completely pushed out of the first and second recesses 23,24. Then snap the catch 9,10 under the pressure of the rotary latch springs 27 in its open starting position ( Fig.1 ) until the nose back walls 63 abut the slot edges 19a of the slot 19. The locking pin 18 is pushed out of the lock box 1 by the Auskhlungswandungen 56. After releasing the actuating lever 38, this also conveniently snaps by the pressure of the spring, not shown, into its initial position ( Fig.1 . 4 ) back.

• Wird das Türschloss 1 vom Fahrzeuginneren aus betätigt, wird in analoger Weise, wie bereits oben beschrieben, an dem Handgriff 72 des Handgriffhebels 70 gezogen und dieser gegen die Kraft der Drehfeder 101 in Hebeldrehrichtung 64a (Fig.16) um den Hebellagerungsbolzen 49 verschwenkt. Dabei wird der Drückerhebel 71, dessen Mitnahmevorsprung 96 an dem Stufenboden 87 des Handgriffhebels 70 anliegt, von dem Handgriffhebel 70 mitgenommen und ebenfalls ohne Verzögerung in Hebeldrehrichtung 64 um den Hebellagerungsbolzen 49 verschwenkt. Dabei werden, wie oben bereits beschrieben, die Auflagevorsprünge 40 über die anliegenden Betätigungsflächen 66a des Drückerhebels, bzw. aufgrund der Drehung des Drückerhebels 71 über die Betätigungskante 69a, von den Betätigungsnasen 43a des Drückerhebelbetätigungsabschnitts 42a formschlüssig mitgenommen und dadurch die Sperrklinken 29,30 gegen den Druck der Klinkendrehfedern 14 und, aufgrund der hinterschnittenen Ausführung der Drehfallenrastnasen 21,22 gegen den Druck der Drehfallenfedern 27, um die Klinkenlagerungsbolzen 34 gedreht.

In the embodiment of the door lock 1 with the two-part operating lever 38a, the actuation of the pawls 29,30 is as follows:

• If the door lock 1 is operated from the vehicle interior, is pulled in an analogous manner, as already described above, on the handle 72 of the handle lever 70 and this against the force of the torsion spring 101 in the lever rotation direction 64a ( Figure 16 ) is pivoted about the lever support pin 49. Here, the trigger lever 71, the driving projection 96 rests against the stepped bottom 87 of the handle lever 70, taken from the handle lever 70 and also pivoted about the lever support pin 49 without delay in lever rotation direction 64. In this case, as already described above, the support projections 40 on the adjacent actuating surfaces 66a of the lever lever, or due to the rotation of the lever lever 71 via the actuating edge 69a, positively entrained by the operating lugs 43a of the Leückerhebelbetätigungsabschnitts 42a and thereby the pawls 29,30 against the Pressure of the pawl torsion springs 14 and, due to the undercut execution of the Drehfallenrastnasen 21,22 against the pressure of the rotary latch springs 27, the pawl bearing bolts 34 is rotated.

After releasing the handle lever 70 this snaps back by the pressure of the torsion spring 101 in its initial position. Also, the trigger lever is pivoted back by the torsion spring, not shown, against the lever rotation direction in its initial position until it strikes again with its driving and stop surface on the bottom of the stage.

The handle lever and the trigger lever are thus coupled to each other in operative connection, that the rotational movement of the handle lever in lever rotation direction 64 on the trigger lever, in particular without delay, is transferable. The rotational movement of the handle lever against the lever rotation direction 64 is not transferable to the trigger lever.

If the door lock 1 is actuated from the outside, presses an unillustrated actuator, such as a button, not shown, known per se, on the pressure surface of the trigger lever in the door closing direction 57 on it, so that the trigger lever is pivoted again in the lever rotation direction 64a about the lever support pin 49 and thereby actuating the pawls. Because the driving and stop surface of the stepped bottom of the handle lever 70 lifts, the handle lever 70 is not actuated by the push button and not taken from the trigger lever 71. The handle lever 70 is actuated by the torsion spring 101 in its non-actuated position (FIG. Figure 18 ) held. Only the trigger lever is therefore in operative connection with the push button.

After retraction of the actuating element of the push button, the trigger lever 71 pivots back to its original position due to the force of the pawl torsion springs 14 or the torsion spring, not shown, as already explained above.

Of course, it is also within the scope of the invention to provide two pawls 29,30 actuated actuating lever 38.

In order to minimize the forces acting on the locking pin 18 and the locking pin recess 61 in the lock case 2 and partially on the rotary latches 9,10 when closing and opening a tilted vehicle door, according to the invention an additional finding, centering, and guide means for Finding, centering and guiding the vehicle door with respect to the body provided during the opening and closing of the vehicle door. This finding, centering, and guide means comprises a finding, centering, and guide member 104 of positive shape, which is in firm connection with the vehicle body 109, in particular the locking pin 18, and that when closing and opening the vehicle door with a Gegenfindungs-, -zentrierungs- and -führungselement 105 cooperates with the corresponding negative mold, which is in firm connection with the vehicle door, in particular the lock case 2.

Of course, it is also within the scope of the invention to fasten the two elements 104, 105 inversely to the vehicle body 109 and to the vehicle door.

The finding, centering and guiding element 104 connected to the locking bolt 18 is a plate-shaped finding, centering and guiding wedge 106, which is arranged on an end face 110 of the locking bolt 18 opposite the fastening plate 107. The finding, Centering and guide wedge 106 in this case has a, preferably flat, the mounting plate 107 facing wedge back 111, a suitably parallel and opposite wedge front side 112 and a perpendicular thereto wedge peripheral wall 113. The wedge front side 112 and the wedge rear side 111 are preferably aligned perpendicular to the locking pin axis 108.

The wedge peripheral wall 113 has to form the wedge shape in a view in the direction of the locking bolt axis 108 a conical shape with two opposite and converging Keilgleitkanten 114a, 114b, which merge into each other in a rounded Keileckkante 115 and preferably an angle a from 15 to 30 °, preferably 18 to 24 ° with each other. Expediently, the finding, centering, and guide wedge 106 is arranged symmetrically with respect to a wedge midplane 116 aligned perpendicular to the wedge front side 112 and has a triangular shape in a view in the direction of the locking pin axis 108. The thickness of the finding, centering and guide wedge 106, that is to say the extent of the wedge peripheral wall 113 or of the wedge sliding edges 114a, 114b in the direction of the pin axis 108, is preferably 5 to 10 mm, preferably 4 to 7 mm.

The locking pin 18 and the finding, centering and guide wedge 106 are connected to each other in the vicinity of the Keileckkante 115, wherein the locking pin 18 is also arranged symmetrically to the wedge center plane 116. Preferably, the locking pin 18 is bolted to the finding, centering, and guide wedge 106. For this purpose, the locking bolt 18 has, for example, a central through hole 117 with respect to the locking bolt axis 108, and the finding, centering and guiding wedge 106 has a cylindrical screw receiving recess 118 extending from the wedge front side 112 to the wedge rear side 111 in the vicinity of the key edge 115. Figure 22 ). In addition, a through hole 119 is inserted in the mounting plate ( Figure 22 ), which is arranged in alignment with the through hole 117 of the locking bolt 18. In the Schraubenaufnahmeaussparung 118, the through hole 117 and the through hole 118, a screw 120 is inserted, which by means of a nut 121 biases the locking pin 18 with the mounting plate 107 and the finding, centering and guide wedge 106.

In order to prevent twisting of the finding, centering, and guide wedge 106, the finding, centering and guide wedge 106 is expediently additionally firmly connected, in particular screwed, to the fastening plate 107 at a second location (FIG. Fig.19,20) , For this purpose, the finding, Zentrierungs-, and guide wedge 106, for example, another from the wedge front 112 to the rear wedge 111 111 continuous, cylindrical Schraubenaufnahmeaussparung 122, which is provided in the region of the Keileckkante 115 opposite wedge side edge 123 of Keilumfangswandung 113. In addition, a connecting and spacing bolt 124 is provided with a central passage recess 125 which is positioned perpendicular to the locating, centering and guide wedge 106, parallel to the locking pin 18. In addition, a further through hole 126 in the mounting plate 107 is present.

In the second screw receiving recess 122, the through hole 125 of the connecting and spacer bolt 124 and the second through hole 126 of the sheet 107 is also a screw introduced by means of a nut (not shown) the connecting and spacing bolt 124 with the mounting plate 107 and the Findungs , Centering, and guide wedge 106 braced.

The distance between the two pins 18,124 from each other is dimensioned so large that the locking pin 18 is encompassed by the rotary trays 9,10.

According to a further embodiment of the invention ( Fig.21,22 ) is the finding, centering and guide wedge 106 fixedly connected via a web plate 127 with the mounting plate 107, wherein the web plate 127 is integrally formed on the wedge side edge 123 of the finding, centering and guide wedge 106 and preferably perpendicular to the plate-like finding , Centering, and guide wedge 106 and the mounting plate 107 extends and is also integrally formed thereon. Such a design is very simple, since the mounting plate 107 and the locating, centering and guiding wedge 106 are manufactured as one unit can be omitted and an additional assembly step and additional parts omitted.

For receiving, guiding, Finduhg and centering of finding, Zentrierung-, and guide wedge 106, the lid 4 of the lock box 2 instead of the bell-shaped locking pin recess 61 a V-shaped or funnel-shaped finding, centering, and -Führungsaussparung 128, the is formed symmetrically to the transverse center plane 15 of the door lock 1 and extends from a lid longitudinal edge 129 in the lid 4 and continuously from the lid outer wall 51 to a lid inner wall 131. The finding, centering and guiding recess 128 is bounded by a recess wall 132, which has two counter sliding surfaces 133a, 133b for the wedge sliding edges 114a, 114b, which merge into one another via a rounded wall corner edge 134.

In addition, additional guide projections 140 are preferably integrally formed on the lid longitudinal edge 129 on both sides of the finding, centering and guiding recess 128 in order to lengthen the counter-sliding surfaces 133a, 133b.

The course of the recess wall 132 seen in a view perpendicular to the lid outer wall 51 ( Fig. 25 ) corresponds to the course of the wedge peripheral wall 113 of the centering of the finding, centering, and guide wedge 106 in the view in the direction of the locking pin axis 108, wherein the finding, centering and guide recess 128 seen in the direction perpendicular to the lid outer wall 51 substantially is arranged in alignment with the locking bolt recess 61 provided in the longitudinal wall 6 and the bottom plate 3.

In addition, the recess wall 132 has an extension in this direction of preferably 10 to 20 mm, preferably 12 to 16 mm.

To further reduce weight and to provide good sliding properties, the entire cover 4 is suitably made of plastic and has stiffening ribs 135. The finding, centering and guide wedge 106 is preferably made of metal or plastic.

• In einer geöffneten Stellung des Türschlosses 1 befinden sich der Schließbolzen 18 und der Findungs-, Zentrierungs-, und Führungskeil 106 außerhalb des Schlosskastens 2 zwischen den Auskehlungen 17 der beiden Drehfallen 9,10. Wird die Tür geschlossen, so drückt der Schließbolzen 18 entgegen der Türschließrichtung (Pfeil 57) gegen Auskehlungswandugen 56 der Drehfallen 9,10 und verdreht diese in oben bereits beschriebener Weise, und wird dadurch in die Schließbolzenaussparung 61 des Schlosskasten 2 eingeführt. Gleichzeitig wird dabei der mit dem Schließbolzen 18 fest verbundene Findungs-, Zentrierungs-, und Führungskeil 106 mit der Keileckkante 115 voraus in die Findungs-, Zentrierungs-, und Führungsaussparung 128 eingeführt, wobei bei schief eingehängter Fahrzeugtür die Einführung nicht zentriert erfolgt, sondern eine der beiden Keilgleitkanten 114a,114b, üblicherweise die obere Keilgleitkante 114a, an einer der beiden Gegengleitflächen 133a,133b, üblicherweise der oberen Gegengleitfläche 133a, entlang gleitet. Dadurch werden die zur Zentrierung der Fahrzeugtür aufzubringenden Kräfte, also üblicherweise die durch die schief nach unten hängende Fahrzeugtür wirkenden Gewichtskräfte, von der oberen Gegengleitfläche 133a auf die obere Keilgleitkante 114a übertragen und nicht der Schließbolzen 18 und die Drehfallen 9,10 und die Schließbolzenaussparung 61 damit belastet.

The mode of operation of the finding, centering and guiding device according to the invention will now be explained in more detail below:

• In an open position of the door lock 1 are the locking pin 18 and the finding, Zentrierungs-, and guide wedge 106 outside of the lock case 2 between the grooves 17 of the two rotary trays 9,10. If the door is closed, the locking pin 18 pushes against the door closing direction (arrow 57) against Auskhlungswandugen 56 of the rotary trays 9,10 and rotated them in the manner already described above, and is thereby inserted into the locking pin recess 61 of the lock case 2. At the same time the finding, Zentrierungs-, and guide wedge 106 is firmly inserted with the Keileckkante 115 in the finding, Zentrierungs-, and guide recess 128 with the locking pin 18 firmly, with a hinged hinged vehicle door, the introduction is not centered, but one of the two wedge sliding edges 114a, 114b, usually the upper wedge sliding edge 114a, slides along one of the two counter sliding surfaces 133a, 133b, usually the upper counter sliding surface 133a. As a result, the forces to be applied for centering the vehicle door, that is to say the weight forces acting through the obliquely downward vehicle door, are transferred from the upper counter slide surface 133a to the upper wedge slide edge 114a and not the lock pin 18 and the rotary latches 9, 10 and the lock pin recess 61 therewith loaded.

Due to the conical shape of the Keilgleitkanten 114a, 114b and the Gegengleitflächen 133a, 133b and the associated wedging action, the vehicle door is thereby continuously more centered and optionally raised the farther the locating, centering and guide wedge 106 in the finding, centering, and guide recess 128 is inserted. In the centered end position, in which the rotary latches 9,10 are in their locked position and completely enclose the centered locking pin 18, also the finding, centering, and guide wedge 106 is fully inserted into the finding, centering, and guide recess 128 and is determined by the finding, Centering and guide recess 128 positively enclosed.

Similarly, when opening the vehicle door, the finding, centering, and guide wedge 106 is continuously led further out of the finding, centering, and guide recess 128, again with the upper wedge sliding edge 114a sliding along the upper mating sliding surface 133a, so again no additional weight forces of the vehicle door on the locking pin 18 and the locking pin recess 61 act.

In the vehicle door lock according to the invention is advantageous that the release forces during opening and closing of the door lock are significantly lower than when using only one pawl, so that the increasingly larger and heavier doors are easily and conveniently opened and closed by the use of two pawls can be.

Furthermore, a synergistic effect is achieved by the execution of the door lock according to the invention with two pawls, since the rotary traps can be designed completely symmetrical, which considerably simplifies the production and also the assembly, since there is no longer the risk that the two rotary traps interchanged installed become.

Another advantage is that the vehicle door lock according to the invention has only a small number of individual components. The operation of the two pawls is advantageously carried out directly via a single operating lever, which in turn is operated directly from the vehicle interior. As a result, on the one hand, the production cost is significantly reduced, on the other hand, not a multi-part lever system, for example, set with screws on each other and readjusted after repeated actuation during assembly.

Due to the undercut and positive execution of the pawl detents, as well as the corresponding indentations or undercuts the locking recesses of the rotary traps and thereby engaging effect a very good safety lock is guaranteed, as the pawl latches on a large Surface of the recesses rest and when opening additionally the rotary latch springs must be stretched slightly.

An advantage of using the two-part operating lever is that the handle lever is not pivoted with the operation of the door lock from the outside, with the construction of the two-part operating lever is surprisingly easy.

By means of the finding, centering and guiding device according to the invention, the forces normally acting on the locking bolt when opening and closing a vehicle door hinged are absorbed and thus the locking bolt and the rotary traps and the locking bolt recess are not loaded and not bent. The forces are already absorbed by the projecting guide protrusions before the bolt could contact the striker hole. As a result, the life of such a vehicle door lock is considerably increased. In addition, due to the relatively narrow V-shape of the locating and centering and guiding wedge and the locating, centering and guiding recess, the locating and guiding device has a relatively small clearance in a direction perpendicular to the transverse center plane of the door lock, so that the centering takes place with little play.

Of course, the use of the invention finding, centering and guiding device is not limited to a door lock with two pawls, but is suitable for any door lock with a locking pin and at least one surrounding this rotary latch.

Moreover, it is also within the scope of the invention, e.g. For very heavy vehicle doors provide a further finding, centering and guide recess in the bottom plate and a second locating, centering and guide wedge to better distribute the forces.
