Although the same rotational position of the lock parts as in Fig. 11, but in an alternative application where, instead of the motor, return springs, the lock parts back to their ready position for closing the flap acc. Fig. 4b can lead back.

The lock shown in the figures is preferably used with a flap that belongs to a glove box. For this purpose, the movable flap 11 is shown schematically in FIG. 1 and the dormant compartment border 12 indicated. In the present case, the mobile one Flap 11 a frame with a here designed as a bolt with a round cross-section Locking part 10, while the compartment 12 sits a lock housing 19, from which a with the locking part 10 cooperating rotary latch 21 protrudes. It is understood that the lock parts 10, 19 also in a mirror image sense compared to the movable and resting element 11, 12 of the glove box could be arranged.

The most important of the lock parts provided in the lock housing 19 are shown in FIGS. 2 to 4b shown. In the lock housing 19, an axle shaft 13 is rotatably mounted, which is an assembly 20th forms from a plurality of non-rotatably connected components 21 to 23. The unit 20 can therefore be rotated as a whole and is therefore referred to below for short as "rotating unit". This rotary unit 20 first includes the fork-shaped rotary latch 21, in which when the flap is closed, according to the movement arrow illustrated in FIG. 4a 15, the closing part 10 moves into the fork opening. At an axial distance from it is in Inside the lock housing 19, a rotary latch 22 which has a pre-locking stage 24 and a End stop 25 for a pivotable locking pawl 16 has. The pawl 16 is in the sense of arrow 17, spring-loaded on the catch 22. Even the whole turntable 20 is spring-loaded in the swivel-up direction of the rotary latch 21, as in FIG Force arrow 27 is illustrated. The pivoting position of the rotary latch shown in Fig. 4a 21 is limited by a schematically indicated stop 26 in the housing which the spring load 27 normally keeps the rotary latch 21 pressed. This Swing-open position is in the open position of the flap.

In the lock housing 19 there is a transmission acted upon by an electric motor 40 30. The transmission 30 includes several transmission groups, one of which is special Gear group 36 is variable in position, in the present case by Tilt, as a comparison between Fig. 2 and Fig. 3 shows. The input link of the The transmission 30 is a worm 41 driven by the motor 40, which is in a worm wheel 31 intervenes. The worm wheel 31 is rotatably connected to a spur gear 32 and on the Axle shaft 13 freely rotatable. The spur gear 32 meshes with a gear 33 which rotates with a pinion 34 is. This assembly 36 of the gear parts 33, 34 has a shaft 14 which, in a first application of the lock, normally parallel to the axle shaft 13 runs. In this case, the pinion 34 meshes with a spur gear, which is also designed special output member 35 of the transmission 30. Then the transmission group 36 is in its effective engagement position, where the rotation from the motor 40 on the Output member 35 is transmitted.

As shown in FIG. 3, the transmission group 36 can be actuated by a multi-unit actuator 50 in a position 36 'tilted by the angle 18 according to FIG. 3, where the pinion 34 no longer engages in the toothing of the output member 35. The self locking of the Gebriebes 30 is canceled. The tilted position 36 'of this gear group can as "Separation position" are called.

The output member 35 is hollow, as best seen in Fig. 2b, and serves to receive the driver 23 of the turntable 20. The output slide 35 is included provided with an axial cam 37, the axial end face of which is illustrated in FIGS. 4a to 13 is highlighted by hatching. This cam 37 determines a radial one Control surface 47. In addition, the driven gear 35 has two recognizable from FIG. 4b Shoulders 38, 39, which two counter shoulders 28, 29 are assigned to the rotary latch 22. The two shoulders 38, 39 from the output member 35 and the two counter shoulders 28, 29 are oriented in opposite directions to each other, as can be seen from FIG. 4b. It is remarkable that between the shoulder and counter shoulder 28, 38 an angular space 48 consists. A corresponding free space 49 also exists between the other pair 39, 29 of the two shoulders and counter shoulders.

4a, 4b, the driven member 35 is in a standby position for Closing the flap, which is here in its full open position. In the The standby position of FIG. 4a is supported by the locking pawl 16 due to the mentioned Spring load 17 on the peripheral surface 42 of the rotary latch 22. The flap will now first moved manually in the direction of its closed position, the one located on it Lock bolt 10 is moved in the sense of the arrow 15 already mentioned and thereby on the Turnbolt 21 bumps and takes it away. It first finds a manual one Swiveling movement of the rotary latch 21 in the direction of arrow 58 of Fig. 4a instead, the Entire turning unit 20, including the driver 23, against the acting spring load 27 is pivoted. The counter shoulder 28 is increasingly moving away from her to Output member 35 belonging shoulder 38. The output member 35 remains at rest until the out Fig. 5 apparent position of the rotating unit 20 is reached.

5, the rotating unit 20 is in a so-called “pre-latching position”, where the pawl 16 due to their spring load 17 in the pre-locking stage 24 of the dash-dotted lines Catch 22 has occurred. In this case there is a "gap position" of the flap. 5 has the counter shoulder 28 off the shoulder 38 due to the manual movement 58 maximally moved away. This locked position is recognized by sensors that are now the motor Energize 40. Via the gear 30, the driven member 35 is now in the direction of swiveling 5 rotated further. The shoulder 38 of the driven gear 35 meets the Counter shoulder 28 of the driver 23 hits. As a result, the entire rotating unit becomes 20th pivoted, as can be seen in Fig. 6. The pre-locking stage 24 is removed Rotary latch 22 from the spring-loaded pawl 16. Because the locking bolt 10 in the Fork opening of the rotary latch 21 has already been retracted sufficiently, it will now be at the pivoting movement 58 carried by the rotary latch 21, which is why the Motor further closes the flap.

In Fig. 7, the motorized pivoting movement 58 via the output member 35 is ended. The Turning unit 20 with its rotary latch 21 is in a final locking position; the Pawl 16 has fallen into the final catch 25 of the rotary latch 22. That will be through Detected sensors that brake the engine. In addition, the Reverse direction of motor rotation; a reverse rotation begins, through which over the Gear 30, the driven gear 35 first in the swivel-up direction according to arrow 59 of FIG. 7 is turned back. This reverse rotation does not apply to the rotating unit 20; the Turnbuckle 21 and the locking bolt 10 gripped by it remain in full Swing position and hold the locking bolt 10 firmly. This is the full closed position the flap secured.

The latter is retained when the output member 35 rotates back in Swing-up sense 59 ended according to FIG. 8a. This can be recognized by sensors and be prompted. In this position, the shoulder 38 on the output member 35 has the Counter shoulder 28 of the driver 23 removed. In between is a big one, through which Angle 61 in FIG. 8a illustrates the free space. Also between those at the previous one Consideration of shoulders and counter shoulders 39, 29 which have not yet become active clearance indicated by the angle 62. The same rotational position is again of the output member 35 as in Fig. 4a, 4b. As with the location of the hatched lines Cam 37 can be seen. The position of the turntable 20 is in opposite directions; while in 4a, 4b is the fully swung open starting position, the rotary unit is located 20 in Fig. 8a in its fully swiveled final locking position. This is in Fig. 8a Output member 35 again in a "standby position", as in Fig. 4a, 4b, but for Open the flap in the sense of the pivot arrow 59 shown on the rotary latch 21. The manual opening of the flap is initially not possible, however, because the output member 35 is in engagement with the other links of the transmission 30 and between these links there is a self-locking. Above all, however, the movement in the pivoting direction is 59 excluded because the pawl 16, the assembly 20 via the rotary latch 22nd holds in its end stop position recognizable from FIG. 8a. In this application the The invention is therefore, as will be explained in more detail with reference to FIG. 9, a motor Opening movement provided.

An emergency situation can now occur where in the standby position of FIG. 8 or in a preceding or following intermediate position of the output member Power supply fails and motorized opening of the flap is impossible. The However, the invention enables a manual swiveling movement by setting it in effect of the special actuator 50 already mentioned in connection with FIG. 3, based on 8b is to be explained in more detail.

The actuator first includes a working lever 51 which can be seen in FIGS. 8a and 8b and which, like indicated by dashed lines, the tiltable end of the axis 14 of the indicated gear group 36 stores. In the normal case, according to FIG. 8a, the working lever 51 is provided by a support lever 52 recorded, whereby the already described in connection with FIG. 2 Engagement position 36 of this assembly is present. The actuator 50 is no longer over shown trigger triggered, which on a pull rope 53 one in its last section in Fig. 8a, 8b shown Bowden cable 54 belongs. The pull rope 53 engages the support lever 52, the then from its effective position 52 shown in FIG. 8a to its position shown in FIG. 8b ineffective position 52 'is transferred. The working lever 51 is under the effect a lifting spring indicated by the force arrow 57, which in the case of the in Fig. 8b Transferring the working lever to the pivoting position 51 'shown in FIG. 8b. Thereby reaches, as indicated by the end of the axis 14, the transmission group in its already 3, which is the separation position of the transmission 30 features. The gear 30 is decoupled, which is why the self-locking is canceled. The output member 35 can thereby also be seen without a motor in the sense of FIG. 8b Arrow 59 are moved in the opening direction. This happens in the present case automatically, by a return spring 44 recognizable from FIGS. 2, 2a, with its two Spring leg 43 holds two pins 45, 46 between them and for their radial alignment 2a provides. One pin 45 sits on the output member 35, while the other Pin 46 is fixed to the housing, that is to say inside the one indicated in FIGS. 2a and 2 Lock housing 19 sits. According to FIG. 8b, the pivoting movement of the Working lever in its pivoting position 51 'by a coupling rod 55 in Coordination with the support lever, which then acts in its ineffective position 52 '.

An elongated hole guide or the like ensures that this is coordinated resulting swivel movement paths. There is another coupling rod 56 between the pawl 16 and the working lever 51, where also a suitable longitudinal guide for a Coordination of movements ensures. Through this further coupling rod 56, according to Fig. 8b, by the working lever brought into the pivoting position 51 'also one coordinated pivotal movement of the pawl 16, which is from its effective Engagement position in the rotary latch 22 according to FIG. 8a in its ineffective release position 16 'of Fig. 8b is pivoted against its spring load 17. Then the catch 22 does not more blocked at their final stop level 25. The whole rotating unit 20 is free and can therefore in Arrow 59 can be moved in the swivel-up direction. This can be done by the effect the return spring 44 described above happen. But there is also the Rotary lock 21 of the rotating unit 20 under the effect of the already in connection with Fig. 4a explained spring force 27, which is effective in the same sense 59. This allows the The rotary latch 21 can be pivoted open again until it is the other one shown in FIG. 4a Ready position reached. During this swiveling movement 59, the locking bolt 10 released, and the flap reaches its full open position.

The above-described cancellation of the gear self-locking by the separating position 36 ^{2 of} the gear group is particularly important when the emergency; which was used to trigger the actuator 50, in the previous intermediate positions shown in FIG. 6 or 7. Here, namely, the automatic resetting of the rotating unit 20 in the swivel-up direction 59, which is due to spring force, would not be possible, because during this backward rotation the driver 23 with its counter shoulder 28 abuts or rests against the shoulder 38 belonging to the output member 35. This is not to be feared in the situation of FIG. 8a, which, as said, follows identically in FIG. 8b. As already mentioned above, the output member 35 with its shoulders 38, 39 is already in a position which corresponds to the pivoted-open position of FIGS. 4a, 4b; the above-mentioned free space 61 is large enough to return the rotary unit 20 to its initial position of FIG. 4a. Normally, however, in this exemplary embodiment of the invention, this is done by motor by the above-mentioned backward rotation of the output member 35 in the swivel-up direction 59, without the actuation 50 previously described having to be triggered.

A motor, which is no longer shown, is used, for example, to switch the motor 40 on accordingly electrical push button. During the movement 59 of the driven wheel 35 according to FIG. 9 bumps finally the shoulder 39 provided there in the area of the cam 37 onto the Counter shoulder of the driver 23. At the same time, the cam 37 with its control surface 47, as illustrated in FIG. 9, has driven against the pawl and already has it in its mentioned ineffective position 16 ', pivoted against their spring load 17. This Swiveling is possible without an effect on the actuator 50 described above, because there is an elongated hole guide in the coupling rod 56 mentioned. This The elongated hole guide allows the actuating movement to occur without any effects on the actuator 50 the pawl through the control surface 47. The turning unit 20 is no longer through the Pawl blocked.

10, the rotating unit 20 is moved by the shoulder 39 of the motor Output member 35 moves over the counter shoulder 29 of the driver 23. It stops the control surface 47 provided on the cam 37 still holds the pawl in its ineffective position 16 ', so that an undesirable incidence in the further motor Rotation 59 in the subsequent pre-locking stage 24 of the rotary latch 22 is excluded.

Finally, the rotary unit 20 becomes in its initial position shown in FIG. 11 achieved by motor rotation 59 of the output member 35. The rotary latch 21 is again brought into its fully swiveled-up position and releases the locking bolt, as in FIG. 11 is indicated by dash-dotted lines. As illustrated by the movement arrow 60, the locking bolts 10 seated on the flap are moved away, thereby bringing the flap back in reaches its full open position. On the way to the swing-open position of FIG. 11, the Overrunning stage 24 of the rotary latch 22 is overrun, but is not activated because the Pawl still from the transmission side control surface 47 in its inoperative position is held.

The passage of the pre-locking stage 24 is again recognized by sensors that are used in this Embodiment of the invention brakes the motor 40 and in again Drives in the opposite direction, that is, in the swiveling direction 58. The resulting ones Conditions are explained in FIG. 12 in an intermediate rotational position of the output member 35. While the rotating unit 20 by abutting its rotary latch 21 against the stop 26 holds due to the spring load 27, removes the previously effective Shoulder 39 from the driven gear 35 opposite the counter shoulder 29 from the driver 23 the driven wheel 35 is further rotated by a motor in the swivel-up direction 59, so it moves in FIG. 12 still effective control surface 47 below that still held in its inactive position 16 ' Pawl gone. Finally, there is the one shown in FIGS. 4a, 4b Ready position of the output member 35, where the control surface 47 of the Pawl 16 has moved away and thereby on the peripheral surface 42 of the catch 22nd supported. The pawl is activated and is under a preload Spring loading 17. In this standby position, however, it cannot yet enter the Latching steps 24 and 25 occur as long as the pivoting position of the turntable 20 is present.

FIG. 13 first shows an emergency actuation that is analogous to that explained with reference to FIG. 8b Relationships. While the driven gear can still be seen in FIG. 11 Rotary position, it is assumed that the power supply or the like fails and a non-motorized opening or closing 58, 59 is to take place. The Swinging up is no longer necessary in the situation of FIG. 11, but it is the emergency could also be in a previous turning position, e.g. Fig. 10 result. In in this case, the pawl is in its inactive position by the control surface 47 16 ', but the self-locking already mentioned several times would be present in the transmission 30, if not, by triggering the actuator 50 in Fig. 13, the transmission group in its Separation position 36 'would have been transferred. Because this is triggered according to FIG. 13 the pressure between the shoulder 39 and the counter shoulder 29 is released, and the restoring action of the return spring 54 described above can take effect. The output member 35 is automatically in its ready position by this spring 44 transferred according to Fig. 4a, 4b. As a result, the rotating unit 20 gets back into it Swing-open position, unless this should already exist, as in FIG. 13.

The actuation of the actuator 50 according to FIG. 13 is also useful when starting out 4a, 4b, an exclusively manual swiveling movement 58 should take place. The Rotary unit 20 can be pivoted manually by the angular amount 63 that can be seen in FIG. 4b 58, although the gear-side shoulder 38 on the drive-side shoulder 28 comes across. The free space 48 explained in FIG. 4b is namely smaller than the angular amount 63 for the rotary movement of the assembly 20 from the pivoted-open position of FIG. 4b into the dotted there made clear, corresponding to Fig. 7 full swivel position. It is also another mode of operation of the invention possible. This can consist in that the The aforementioned gear group 36 is normally always in its on the basis of FIGS. 3, 8b and 13 explained separation position 36 '. That affects the two at first Ready positions for opening according to FIG. 8a and for closing according to FIGS. 4a, 4b not, as has already been explained. Only if, starting from the standby position for 4a, 4b, a closing aid by the motor 40 is desired this gear group in its engagement position 36, so that the workflow according to FIGS. 5, 6, 7 takes place in the manner already described. Then, however, a simplified one occurs Control On. When FIG. 7 is reached, the motor 40 stops the swiveling movement 58 of the output member 35. Then the gear group 36 is replaced by a suitable one Transferring member transferred back into its separating position 36 'according to FIGS. 3, 8b and 13, where the self-locking in the transmission 30 is canceled. The spring forces 27 or the return spring 44 then automatically leads the output member 35 back into the Ready position of Fig. 8a, 8b back, without energizing the motor 40 in Aufschwenks sense 59 may be required. The standby position according to FIG. 8a Output member 35 is caused by spring force. Then the pawl 16 falls into the position shown in FIG. 8a visible final locking position and holds the rotating unit 20.

Then the position-variable gear group 36 can automatically move into it Separating position 36 'of Fig. 3 are transferred, but first the pawl in their engagement position 16 of Fig. 8a remains. In this respect there is a modification to the previously explained with reference to FIG. 8b. If now the turntable 20 back into its swiveled-out position according to FIG. 11 of the previous one Embodiment to take place, is a motorized pivoting movement in the sense of Arrow 59 not necessary. The pawl 16 is sufficient by a suitable control member to be transferred back to their ineffective position 16 'shown in FIG. 8b, where the catch 22 is released. The spring force 27 acting on the rotating unit 20 ensures a spring-related return movement of the rotating unit 20. The return spring 44 described above holds the output member 35 in its ready position, which can already be seen in FIG. 8, which is identical to that of Fig. 4a, which again is the desired standby position indicates to close. This alternative mode of operation therefore simplifies Control of the engine 40.

   a rotary spagnolet (21) in which, during closing (15) of the flap (11) a locking member (10) is inserted and rotates the rotary spagnolet (21) out of an open pivot position, characterizing the open position of the flap, via a split position of the flap into a closed pivot position determining the locked position of the flap,
   with a locking pawl (16) which engages a rotating latch (22) connected rotationally fixedly to the rotary spagnolet (21) when the locking pawl (16) is active,
   and when the rotary unit (20), comprising the rotary spagnolet (21) and the rotating latch (22) has been transferred out of its open pivot position, with the flap in the open position, either into a pre-locking position determining the split position of the flap or into a closed pivot position characterizing the locked position of the flap,
   characterized in that
   the rotary unit (20) has a rotationally fixed catch (23) with two counter shoulders (28, 29) oriented in opposite directions relative to one another,
   that the drive member (35) of a gear mechanism (30) driven by a motor (40) has two shoulders (38, 39) correlated with the two counter shoulders (28, 29),
   that the motor (40) serves at least as a closing aid, optionally also as an opening aid, wherein one of the two shoulders (38; 39) of the drive member (35) impacts respectively on the corresponding counter shoulder (28; 29) of the catch (23) and moves the rotary unit (20) in the closing pivot direction (58) or in the opening pivot direction (59) to the fully closed or open pivot position which defines the closed or open position of the flap,
   that, however, the drive member (35), in the closed or open position of the flap, is rotated back into a defined ready position for opening or closing the flap, wherein between its shoulders (38; 39), on the one hand, and the counter shoulders (28; 29) of the catch (23), on the other hand, a free space (48, 49; 61, 62) is present which allows a manual movement of the flap,
   that the gear mechanism (30) has a position changeable (18) gear group (36) which relative to the rest of the gear mechanism is adjustable between an engaged position and a separating position (36'),
   and that the position changeable gear group (36) is in its separating position (36') at least in the emergency situation and that the locking pawl (16) is inactive (16') when the closed position of the flap is present and the drive wheel (35) is in a ready position for opening the flap.
2. The lock according to claim 1, characterized in that in the closed and open position of the flap the rotary unit (20) has positions different relative to one another, but that the drive wheel (35) is always in the same ready position,
   and that, when the separating position (36') of the gear group (36) is present, a return spring (44) acting on the drive wheel (35) automatically transfers the drive wheel (35) into its ready position.
3. The lock according to claim 1 or 2, characterized in that the locking pawl (16) is spring loaded (17) in the engagement direction,
   and that the drive wheel (35) has a control surface (47) which pushes the locking pawl (16) away (16') from the rotating latch (22) during opening of the flap.
4. The lock according to one or several of claims 1 to 3, characterized in that the position changeable gear group (36) is normally in engaged position and only in the emergency situation is transferred into its separating position (36'),
   and that the return rotation of the drive member (35) into the ready position for opening or closing is realized by a corresponding return movement of the motor (40).
5. The lock according to one or several of claims 1 to 3, characterized in that the position changeable gear group (36) is normally in its separating position (36') and is transferred into its engaged position only during motor driven closing or opening of the flap
   and that the return rotation of the drive member (35) into the ready position for opening or closing is realized by the return springs (44).
