Definitions

  • the invention is directed to a lock of the type mentioned in the preamble of claim 1, e.g. is used in motor vehicle doors or flaps.
  • Such locks are equipped with rotary traps, which have both a pre-rest and a main branch, in which a pawl can come.
  • rotary traps which have both a pre-rest and a main branch, in which a pawl can come.
  • motorized closing aids are used which engage the catch and which move the catch to a final position in which the pawl engages the main catch. This final situation is referred to below as the "main lodge”.
  • a lock of the above type is known from WO 99/49155. Similar locks are also known from DE-A-10043574 and DE-A-19650826.
  • WO 99/49159 a lock is described in which a gear is arranged on a motor drive, which has two output paths. The first output travel can act as a closing aid on the catch and the second output travel as an opening aid on the pawl.
  • a transmission member is provided, via which in each case a driven path can be set effectively, while the other Output path is set inactive, depending on whether the drive is to be used as an opening or closing aid.
  • a lock with a motorized closing and opening aid is also known.
  • an opening aid in the first direction of rotation of the drive a pawl is first actuated via a rotary member arranged on the transmission axis. After release of the catch by the pawl of the second output path is then coupled via drivers to the rotational movement of the axis of rotation and set in operation. The opening movement of the rotary latch is then further supported via the second output path.
  • a closing aid in the second direction of rotation of the drive, a closing movement is transmitted to the rotary latch after a slamming of the door on the second output path while the latch is moved into its locking position on the rotary latch.
  • the object of the invention is to develop a lock of the type mentioned, which works reliably and avoids the disadvantages mentioned above.
  • This is inventively achieved by the measures mentioned in claim 1, which has the following special significance.
  • the peculiarity of the measures described is to provide output gears on a transmission, which are constantly coupled to the drive.
  • the lock according to the invention is inexpensive to manufacture and very reliable due to its simple structure.
  • the activation or deactivation of the output paths can take place via the direction of rotation of the drive. By doing so, the use of a Transfer member and a rear derailleur with additional drive or the use of coupling means for the connection of a driven path superfluous.
  • the pawl must be moved out of the main catch on the rotary latch.
  • the lifting of the pawl is effected by an actuating element, which lifts out the pawl from the main catch or pre-catch on the rotary latch by its radially enlarging in the direction of rotation actuating surface.
  • the rotary latch moves into the open position due to a restoring force acting on it.
  • the door lock includes a rotary latch 20, which is under a restoring force F1 of a spring 23.
  • This spring 23 is placed on a mandrel 28 of the rotary latch 20 and moves within a receiving channel 14 of the housing 11.
  • the rotary latch 20 shown is pivotally mounted on a journal 21 in the housing 11 and is normally attached to the door not shown in detail. Instead of a door, it could also be a flap, e.g. Tailgate of a motor vehicle act.
  • the rotary latch 20 has a slot-shaped receptacle 24 for a here bow-shaped closing member 13. When the closing member 13 is removed from the rotary latch 20, as shown for example in Fig.
  • the closure member 13 is normally attached to a post of the door. The arrangement of the closing part 13 can also be done on the door, the rotary latch 20 is then positioned with its housing 11 fixed to the post.
  • the catch 20 has at least two notches 25, 26, namely a pre-catch 25 and a main catch 26. In these notches 25, 26 engages a pawl 30 with a latching hook 34 when the catch 20 in its already mentioned Vorrastlage of FIG or is located in one of Fig. 1 apparent final Hauptrastlage.
  • a gap normally remains between the door and the door jamb.
  • a motorized closing aid is provided which engages the rotary latch 20 and the catch moves against the restoring force F1 in the Hauptrastlage, where then the latching hook 34 of the pawl 30, the main catch 26 of the rotary latch 20 engages behind.
  • This Haupttrastlage shown in Fig. 1 is effected by the pawl 30 by a spring force F2.
  • a spring 33 is arranged on the latch 30, which loads the pawl 30 about the pivot axis 31 in the direction of the rotary latch 20.
  • a load lever 50 is further shown, which is pivotable about a pivot axis 51 and held by a spring 52 which is supported on a stop 53 of the load lever 50, in a rest position shown in FIG.
  • This load lever 50 further has a recess 56, in which a bearing pin 41 engages, which shows the axis of rotation for a better shown in Fig. 2 actuator 40.
  • This Fig. 2 shows the catch 20 and the pawl 30 also in the main latching position. In this case, the representation of the load lever 50 was omitted in order to better illustrate the actuating element 40.
  • This actuator 40 has a radially increasing in the direction of rotation 42 actuating surface 44 and a locking surface portion 45, which, as will be described later, after the lifting of the pawl 30 is driven by a locking element 37 of the pawl 30.
  • This actuator 40 has in Fig. 2 is still no contact with the pawl 30th
  • the rotary latch 20 strives to move in the opening direction of rotation 22 due to its restoring force F1.
  • the catch 20 is prevented, as shown in FIGS. 1 and 2, by the pawl 30 therefrom.
  • a drive start signal to the drive part 15 are triggered, said drive member 15, the actuating element 40 in the direction of rotation 42 is set in motion.
  • the drive energy of the drive member 15 is transmitted, for example via a pinion 16 to a gear 43 which is operatively connected to the actuator 40.
  • the gear 43 and the actuator 40 move about the same axis of rotation 41.
  • the gear 43 and the actuator 40 are not only rotationally connected to each other, but in this case even formed in one piece.
  • This Medhublage the pawl 30 is shown in FIG. 5.
  • the actuating surface 44 of the actuator 40 has reached the greatest distance from the axis of rotation 41 and the pawl 30 is at a maximum distance h from the rotary latch 20.
  • the radius of the actuating surface 44 does not change. That is, the pawl 30 remains in this Sprinthublage.
  • the pawl 30 may be additionally equipped with a trigger leg 32 which engages through an opening 18 of the housing 11, with which the pawl 30 can be moved from the locking positions on the rotary latch 20.
  • the pawl 30 has a further arm 35 with an end-side pressure surface 36.
  • this signal switch 17 is released and the signal switch 17 can in this case, the Signal the release position of the latch 30.
  • Fig. 6 the end position of the actuating element 40 in the direction of rotation 42 is shown.
  • the actuating element 40 releases the actuating arm 38 of the pawl 30, so that the pawl 30 pivots in the direction of the rotary catch 20 due to its spring force F2.
  • the actuator 40 move in the reverse direction to the direction of rotation 42, which is not effected by the drive member 15, but can happen due to the load of the actuator 40, this reverse rotational movement is prevented by one end of the actuator arm 38 of the pawl 30 arranged blocking element 37 moves against the locking surface portion 45 of the actuating element 40 and thus blocks the actuating element 40 in the reverse direction of rotation.
  • This blocking can be further assisted by an eccentric disk 46 provided on the actuating element 40, which in this example is moved about the same axis of rotation 41 and is arranged between the gear 43 and the actuating surface 44.
  • This eccentric disc 46 also has a locking portion 47, which beats at the moment where the locking member 37 of the pawl 30 against the locking surface portion 45 of the actuating surface 44, at a corresponding portion of the arm 35 of the pawl 30, as is apparent from Fig. 6 ,
  • Fig. 6 the open position is shown.
  • the closing part 13 which moves into the slot 12 of the housing 11, displaces the rotary catch 20 by abutting one side of the receptacle 24 of the rotary latch 20 and moving the rotary latch 20 in the closing direction of rotation 29 by a corresponding thrust, the rotary latch 20 first reaches the pre-locking position, in which the latching hook 34 of the pawl 30 engages in the pre-catch 25 on the rotary latch 20.
  • FIG. 7 Upon further rotation in the closing direction of rotation 29 against the restoring force F1 of the rotary latch 20, the rotary latch 20 enters the main latching position, which is shown in FIGS. 1 and 2.
  • the load lever 50 serves as an opening aid, in which it prevents re-insertion of the pawl 30 into the rotary latch 20 after the lifting of the pawl 30 by the actuating element 40.
  • the rotary latch 20 in its movement in Opening direction 22 blocked by snow load or ice, although a signal to the drive element 15 is triggered, whereby the actuator 40 moves the pawl 30 out of the main latching position or the pre-latching position, the rotary latch 20 remains in the main latching position or the Vorrastlage.
  • the pawl 30 has already been swung out by actuation of the actuating element 40 and is prevented by the load lever 50 from falling back into the main catch of the rotary latch 20. If the blockage of the rotary latch 20 is released, for example, the ice in the lock 10 melts, the rotary latch 20 can automatically move in the opening direction of rotation 22 due to the restoring force F1. During this rotational movement, the rotary latch 20 comes with its shoulder 27 in contact with the load lever 50, said shoulder 27 presses against a peripheral portion 55 of the load lever 50. This is shown in FIG. 9. Since the spring force F1 of the rotary latch 20 is greater than the spring force F4 of the load lever 50 it is pivoted against the spring force F4 about its axis of rotation 51.
  • the recess 56 preferably has a pivoting movement 57 aligned longitudinal extent, so that the pivot pin, which is the axis of rotation 41 of the actuating element 40, in the rest position of the Load lever 50 is preferably located at one end or centrally in the recess 56 and abuts in the pivoted position of the load lever 50 at the other end of the recess 56.
  • the load lever 50 releasing the pawl 30 moves in the opposite direction of rotation to the opening direction of rotation 22 of the rotary latch 20.
  • Fig. 11 the open position of the door is then shown.
  • the locking element 13 is located outside the rotary latch 20.
  • the rotary latch 20 is in the rest position and the load lever 50 is held by the rotary latch 20 in its pivoted position.
  • the load lever 50 pivots back to its rest position only when closing, ie moving the catch in the closing direction 29, the shoulder 27 of the catch 20 releases from the load lever 50 and allows pivoting back of the load lever 50 in the rest position.
