Definitions

  • the invention is directed to a lock referred to in the preamble of claim 1.
  • the lock is normally located in the region of the door or the flap and has a catch.
  • the lock and the closing part can also be arranged in opposite directions on the door or on the door jamb.
  • the Vorrastlage the catch is secured by a stationary rotatably mounted pawl, which is spring-loaded towards the catch and incident in a catch provided for a pre-catch. It is also provided a reversible drivable engine with an associated control for switching on and off. The engine cooperates with both a motorized closing aid and a motorized opening aid for the door or flap, via a gear with at least one eccentric. About the Zuzieh Vietnamese the catch is transferred from the eccentric into a Haupttrastlage, which is also secured by the pawl. In the main position, the pawl falls into a provided on the catch main catch.
  • the invention has for its object to develop a reliable lock referred to in the preamble of claim 1 species, which is relatively space-saving training and allows even in case of failure of the electronics actuation. This is inventively achieved by the measures listed in claim 1, which have the following special significance.
  • the eccentric or eccentric acts only indirectly on the rotary latch or on the latch.
  • the respective eccentric works eccentrically rotatably mounted on the catch locking lever of the closing aid or a rotatably mounted on a stationary rotatably driver opening lever the opening aid.
  • Both the closing lever and the opening lever are held by a respective pulse spring in a defined center position. In this middle position, the eccentric interacts with the closing lever only in the pre-locking position and transfers the rotary latch to its main locking position when the eccentric is rotated in one direction. If the catch is in its main catch position or in its open position, then the closing lever is arranged outside the driving path of the eccentric and is not actuated.
  • the opening lever which is aligned in the main load position with its working end with the rotational path of the eccentric. Then, the eccentric despite the free movement of the opening lever exert a torque on the driver when the rotation of the eccentric takes place in the opposite direction. As a result, the pawl is taken and lifted out of the main catch position of the catch. The catch is then transferred from its own spring load to its open position. So that the catch has sufficient time for it, profiles and counter profiles between the opening lever and the eccentric provide. However, the opening lever is positioned both in the open position and in the pre-locking position of the driver so that upon rotation of the eccentric in one direction, the opening lever is pivoted away against the action of its pulse spring and exerts no actuation pressure on the driver.
  • the opening lever After passing the eccentric, the opening lever returns to its central position by means of its pulse spring. When rotated in the opposite direction of the opening lever is detected by the eccentric and pivots the driver and thus the pawl back.
  • a free distance between a shoulder on the driver and a counter-shoulder on the pawl is arranged both in the open position and in the pre-rest position.
  • two separate eccentrics should be used for the closing aid and opening aid, they can be very close to each other in the invention, which saves space in the castle. It is particularly space-saving, however, if one arranges the two eccentric axially aligned on a common transmission output of the engine.
  • a rotary latch 30 which has a profiled incision 34 for receiving a closing part 35.
  • the closure member 35 may be formed as a bolt or as a web of a bracket and is seated on the fixed door jamb.

  • the eccentric 11 carries out the rotation 13 in the clockwise direction of the drawings further and initially releases the butt end 14 of the closing lever 10.
  • the spring load 36 then rotates the rotary latch 30 slightly until its main catch 32 is supported on the pawl locking end 41. This is shown in Fig. 5a.
  • the catch is then in its by the auxiliary line 30.2 in Fig. 5a clarified "main catch position".
  • This main locking position 30.2 is also shown in Fig. 4a.
  • the closing part 35 is from its in Fig. 5a indicated by dash-dotted lines and illustrated by the contour line 35.1 Vorrastposition corresponding to that of Fig. 2a and 3a, the distance piece 19 reaches the solid line position 35, which is represented by a contour line 35.2 in FIG 5a is marked.
  • the flap provided with the lock is tightened against the action of the elastic door seals around the path 19 Service.
  • the electrical control suspends the engine when the eccentric 11 has reached, for example, the "12 o'clock position" shown in FIG. 5a, which preferably also existed in the starting position of FIG. 1a. In Fig. 5a, the flap is properly closed.
  • the lock is also provided with a motor opening aid to it, starting from the main latching position 30.2 of Fig. 5a to be able to open comfortably.
  • the opening aid is controlled by the same engine and in this case even by the same gearbox.
  • This is served by a second eccentric 21 apparent from FIG. 6b, which is arranged in a different plane from the previously described first eccentric 11, but in the present exemplary embodiment sits on the same output shaft 12.
  • the two eccentrics 11, 21 could sit on two different gear members of the engine, which are arranged at a radial distance from each other.
  • the opening aid begins when an authorized person turns on the engine via a switch or by remote control, but then in the already mentioned opposite direction 23 of Fig. 5a, ie in the counterclockwise direction, rotates.
  • both eccentrics 11, 21 sit on the same output shaft 12, both run in the opposite direction 23, ie counterclockwise.
  • the first eccentric 11 executes the already described with reference to FIG. 3b Leerlaufverschwenkung 10.1 of the closing lever 10 shown there fragmented, but then acts, as shown in FIG. 6b, with the following other lock parts of the opening aid together.
  • a driver 50 On a stationary axis 43, which is in the present case at the same time that of the pawl 40, sits a driver 50.
  • the driver 50 is in the same sense as the pawl 40, spring-loaded in the direction of the rotary latch 30, although he in a front of the rotary latch 30th lying level is arranged.
  • the pawl 40 is arranged in the same plane as the rotary latch 30.
  • the driver 50 cooperates via a recessed tab 54 with a projecting arm 46 of the pawl 40.
  • the driver 50 rests on a stop not shown in detail due to its spring load 52 and thereby assumes the by the auxiliary line 50.0 in Fig. 6b clarified rest position.
  • In rest position 50.0 which is still in Fig. 6b, there may be an air gap 17 between the flap 54 and the arm 46.
  • an opening lever 20 At the free end 51 of the driver sitting at a pivot point 22, an opening lever 20. Also, the opening lever 20 is under the action of a pulse spring not shown in detail, the effects of which are again illustrated by an arrow pair 26 in Fig. 6b.
  • the pulse spring 26 ensures that the opening lever 20 is held in a defined center position, which is illustrated by an auxiliary line 20.0 in Fig. 6b.
  • the second eccentric 21 In the course of the aforesaid reverse rotation 23, the second eccentric 21 abuts against the butt end 24 of the opening lever 20, which happens just in FIG. 6b.
  • the opening lever 20 and the driver 50 is pushed away, as can be seen in Fig. 8b.
  • a stationary stop 25 in the lock housing ensures that the opening lever 20 can pivot away from its central position 20.0 only to a certain extent in the opening phase and, above all during the further rotation 23, is not taken away by the eccentric 21.
  • the driver 50 is transferred by an angle 53 in an illustrated by the auxiliary line 50.1 working position of Fig. 8b. In this pivoting 53 takes a shoulder 55 on the driver lobe 54 via a counter-shoulder 45 on the pawl arm 46, the pawl 40 with.
  • the pawl 40 is thereby moved away from the rotary latch 30 against its spring load 42 and its locking end 41 lifted out of the main catch 32 of the rotary latch 30 of Fig. 6b. Then, the rotary latch 30 can swing out due to their spring load 36 in their apparent from Fig.
  • FIGS. 6a to 8a show what happens in the region of the closing lever 10 during the opening phase of the lock caused by the opening lever 20.
  • the decisive for the actual opening aid components namely the second eccentric 21, the opening lever 20 and the driver 50 omitted.
  • the second eccentric 21 has come to the position of Fig. 6b in the reverse rotation 23, of course, on the same output shaft 12 of the transmission seated first eccentric 11 transferred to the apparent from Fig. 6a position.
  • the first eccentric 11 is slidably past the butt end 14 of the closing lever 10, without being able to act on the pawl 40.
  • the pawl 40 remains in engagement with the main catch 32, whereby the main latching position 30.2 initially remains guaranteed. This changes only at the transition from Fig.
  • FIG. 7 a shows an intermediate position of the first eccentric 11 during this counter rotation 23, where the driver 50 shown in fragmentary form has just reached its working position 50.1 by means of the opening lever 20. At the other end, however, the closing lever 10 is just supported on its first eccentric 11, which is why in Fig. 7a the rotary latch 30 is still in its main locking position 30.2 in accordance with Fig. 5a.
  • the pawl 40 with its locking end 41 has already released the main catch 32 on the rotary latch, because the shoulder 55 of the driver on the counter shoulder 45, the pawl 40 has already pushed away.
  • Fig. 3b is also explained what happens at the lock parts of the opening aid when the output shaft 12 is rotated in the direction 13, which causes the closure operation of the flap on the lock members of Fig. 1a to 5a.
  • taking place clockwise rotation of the opening lever 20 is pivoted against the action of its pulse spring from its prescribed center position 20.0, which is also shown as an auxiliary line in Fig. 3b, in a marked by a further auxiliary line 10.1 angular position.
  • This is illustrated in Fig. 3b by the angle 27.
  • This has no effect on the engagement of the pawl 40 in the Rotary latch 30.
  • the pre-locking position 30.1 is present in FIG. 3b, this also applies in the main locking position when the two eccentrics 11, 21 are driven together by the motor in the direction of rotation 13, thus clockwise.
  • the lock according to the invention allows access to the vehicle compartment when the tailgate is closed, even if the engine and / or the power supply fail after reaching the pre-locking position 30.1.
  • a failure of the engine is shown in Fig. 9a.
  • the eccentric 11 has continued in this example by a small portion of the Vorrastlage shown in Fig. 3a and has thereby brought about by means of the dotted locking lever 10 'the dot-dash line indicated pivoting position 30' of the rotary latch.
  • the dot-dashed rotary latch 30 ' is in its illustrated by the auxiliary line 30.5 intermediate layer 30.5.
  • the eccentric 11 could also have continued to run in the sense of the likewise dash-dot clarified rotary arrow.
  • the rotary latch 30 is transferred at least to its overstroke position 30.3 of Fig. 4a or even to a in Fig. 10a by the auxiliary line 30.4 clarified "maximum end position".
  • This end position 30.4 is determined by the fact that the rotary latch 30, as shown in phantom in Fig. 10a, beats with its shoulder 57 at a stationary stop 47. Then, the pawl 40 can be lifted out of the main catch 32 by means of a not shown mechanical emergency operation. As a result, the rotary latch 30 is pivoted back by means of its spring load 36 in its open position 30.0, which is illustrated in Fig. 9a by a rotary arrow 29. In the open position 30.0 of FIG. 9a, the rotary latch 30 has released the closing part 35. The tailgate is open.
  • Fig. 9a the tailgate is manually pressed again.
  • the closing part 35 moves into the rotary latch 30 and, as indicated by the arrow 49 in FIG. 10a, pivots the rotary latch again in the direction of its overhanging position 30.3 or end position 30.4.
  • Fig. 10a is sufficient by the auxiliary line 30.6 clarified rotary latch position to get the lock lever 10 free.
  • the lever 10 has in fact been moved back so far in Fig. 10a with its pivot point 15 on the rotary latch 30, that its butt end 14 is outside of the illustrated by the rotary arrow 58 rotation of the eccentric 11.
  • the closing lever 10 which was initially located in its emergency position 10.2 illustrated in FIG. 10a, is automatically turned back into its central position 10.0 due to its impulse spring load 16.
