The door lock shown has a flat lock base plate 1 on which is U-shaped and thus two free U-legs 2, 3 and a base leg 4 (Fig. 1).

The two U-legs 2, 3 can be of different lengths be and are oriented vertically in Fig. 1, the base leg 4 is oriented horizontally. On the outer flat sides of the longer U-leg 2, a lock case plate 5 is arranged.

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 the width of approximately the width of the U-leg 2 and its orientation corresponds. To the Side edges of the base wall 6 are to form a cuboid Lock case 12 two vertical side walls 7 and two horizontal side walls 8 tied.

The vertical side walls 7 and the upper horizontal side wall 8 lie on end faces 9 of the free U-leg 2 on, the lower horizontal side wall 8 is with her End face on the U-leg 2.

In the lock case 12 is approximately in the longitudinal center of one Side wall 7 forth an approximately semicircular or elliptical Recess 13 arranged to accommodate a Door locking bolt 14 creates. The recess 13 extends thus from the vertical side wall 7 to approximately to the center the lock base plate 1 and the lock case plate 5.

The top and bottom of the recess 13 are approximately in the Half of the horizontal extent of the recess 13 each hollow cylindrical axle bolt 15 between the lock base plate 1 and the lock case plate 5, which is the lock base plate 1 and reach through the lock case plate 5 and preferably fasten to each other.

The hollow cylindrical axle bolts 15 can be used for screws to be inserted with which the lock on a door or can be screwed onto a door frame.

Around the horizontal axis bolts 15 are adjacent to the base wall 6 of the lock case plate 5 a rotary latch 16 one above the other aligned and spaced slightly apart. Between the rotary latch 16 and the lock base plate 1 is ever a rotary latch spring 17 is arranged.

The rotary latches 16 are plate-shaped elements, for example Steel plates (Fig. 2). There are one on each catch 16 Bolt nose 19 formed with a groove 18. In open In the closed position, the lugs 19 are above the vertical side wall 7, in which the recess 13 is arranged, laterally beyond the side wall 7. The fillets 18 of the locking lugs 19 of the rotary latches 16 are arranged facing one another.

On the areas of the Stop surfaces 22 are arranged on the peripheral wall of the rotary latches 16.

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) of 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 vertical side walls 7, the springs 17 can but also be connected to these legs. The rotary latch springs 17 endeavor to open the rotary latches 16 Hold position (Fig. 7a, Fig. 8a, Fig. 9a), that is, the facing one another Push the tabs 19 apart.

Adjacent to the grooves 18 on the opposite side of the nose On the side of the grooves 18 there are two adjacent ones Locking recesses 25 in the peripheral wall of the rotary latches 16 arranged.

The locking recesses 25 are approximately V-shaped, but undercut formed so that the recess 25 a short, has undercut flank 25a and a long flank 25b (Fig. 7a). The reasons for the recesses 25 are rounded executed.

On and around the U-shaped lock base plate 1 is a substantially U-shaped unlocking lever 27 arranged (Fig. 1). Of the Release lever 27 has two free U-legs 28, 29 and a U base web 30 connecting them.

The base web 30 is essentially parallel to the U base web 4 the lock base plate 1 arranged. Essentially parallel to Free U-leg 2 of the lock base plate 1 extends Leg 28 or locking arm 26 of the lever 27 in the direction of Lock case and through a recess 31 (Fig. 3) in the Leg 4 facing horizontal side wall 8 in the Lock case 12 into it.

The free end of the leg or latch arm 28 extends up to the level of the two rotary traps (Fig. 8a to 9c).

In the direction of the rotary latches 16, a locking piece 33 is on the side molded onto the free end of the leg 28.

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. 10).

The longitudinal edge 36 of the locking piece 33 and the end edges 34, 35 have common corners 37a, 37b.

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. 10).

The corners 37a, 37b are rounded, the edges 34 and 36a and 35 and 36b each form an acute angle.

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.

The edge 35 is slight from the corner 37b to the leg 28 undercut so that the locking piece 35 to the corners 37a, b becomes somewhat wider in the region of the edge 35 (FIG. 10).

In the safety locked position of the lock, i.e. when the latches 38a, 38b in the respective first recesses in the direction 25 of the rotary latches 16, the corners 37a, b of the locking lugs 38a, b in a form-fitting manner from the locking recesses 25 includes. I.e. the short flanks 25a of the recesses 25 are located on the edges 36a, b and the long flanks 25b on the Front edges 34, 35 on.

In the fully closed position, i.e. if 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. I.e. a catch recess 25 lies with its edge 25b on the front edge 34, the other recess 25 is located with its edge 25a on the front edge 35.

The front edge 35 acts when the locking piece 33 widens advantageously in the correspondingly shaped or undercut Recess recesses 35 led out of the recess 25 the resistance of the torsion trap spring, which is stretched, must be overcome.

Between locking piece 33 and the U-base webs 4, 30 facing horizontal 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 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.

A spring 59 can be arranged around the pivot 57, which is so acts on the lever 27 that the locking piece 33 on the rotary latches 16 is pressed and contacted.

The U-leg 29 extends beyond the pivot 37. Its free end is designed as a balance weight 40 (Fig. 1).

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.

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.

The adjusting screw 45 is opposite to the rotary latches Screwed into the hole 43.

The adjusting 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.

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).

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.

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.

If the screw 45 is to be rotated, the spring 59 must first can be excavated from the cross recess 63.

Between the vertical 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.

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 bolt 15, so that the Locking lugs 19 towards each other and in the door closing direction (Arrow 55) seen behind the door locking bolt.

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, b, 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, b 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.

The lock is hereby held in the closed position.

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, b 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, b completely Get out of the recesses 25, the rotary latch snap 16 under the pressure of the rotary latch springs 17 in their starting position, back to the open position. The door locking bolt is through the walls of the grooves 18 from the Lock case pressed.

The vehicle door lock can be equipped with a child lock be able to open the lock from the inside to prevent (Fig. 3, 4, 6). This is the release lever 27 divided into two parts 27a, 27b, the first part 27a the U-leg 28 protruding into the lock and the U-base web 30 and the second part 27b the free U-leg 29 and the opening handle 42 acting thereon. Between these two parts 27a, 27b of the unlocking lever 27 exists in the area of the branch from the U base web 30 a gap 46 to the U-leg 29 and to the actuating handle 42, by the two parts made in one piece spatially separated are.

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.

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.

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 release lever 27 arranged and acts on it in one directly adjacent to the gap 46.

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.

The locking lever 48 latches in the securing and in the unlocked end position to prevent unwanted locking or unlocking to prevent.

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.

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 (Fig. 8a, 8b, 8c) or, for example, around the pivot 37 of the leg 28 may be arranged, in the latter If there is 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 (Fig. 9b).

The unlocking lever can be made in one piece. Hereby on the one hand, the manufacturing effort is significantly reduced, on the other hand, there is no need for a multi-part lever system during assembly adjusted to each other with adjusting screws and after repeated Press to be readjusted. The lock case and the Parts on which the lever system is articulated form through the U-shaped lock base plate a structural unit. The castle can be mounted on the usual support components without it must be installed directly on or in the door.

By arranging the balance weight on the to the state of Technology opposite lever side prevents the Balance weight in the event of impact or impact Persistence opens, on the contrary the lock becomes even secured.

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, this 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.

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.
