Abstract

The invention concerns a closure comprising a lock cylinder with a cylinder core (33) which can be actuated by a key (34) and can also be moved into a so-called safely secured position (74), with a handle (10) which sometimes acts on a lock transmission member (20), with a switching cam (42) used to actuate a microswitch (50, 50'), and finally with a central-locking member (60) of a central-locking system, which member can be moved into an inactive position (60') and cannot be actively reset again in the safely secured position (74). According to the invention, in order to eliminate the risk of defective operations, the switching cam (42) is provided on a spring-loaded control member (40) which, when the key is turned, can be moved out of a coupling plane (69) into an uncoupling plane (67) where it is uncoupled from the cylinder core (33) and springs back into a normal position as the result of spring force. For other switching functions, the switching cam (42) can carry out lifting movements as the key is turned further after uncoupling. At least part of the transmission member (20) is deflected out of the actuation direction of the handle (10) when the central-locking member (60) is in the inactive position. An abutment face on the control member (40) holds the transmission member (20) in its uncoupling plane in that it located in a second, raised plane. As a result, a previously actuated microswitch is overtravelled without functioning.

Description

The invention is directed to a closure in the preamble of Claim 1 specified type, especially as a rear lock in the trunk lid a motor vehicle is used. With this closure the cylinder core arranged in the locking cylinder can be properly Key from a zero position by a pulse spring is intended to twist in three working positions. After pulsing rotation in a first working position, which is called the "unlocked position" the lock can be opened by operating a handle because a transmission member of the closure is moved by the handle and acts on the castle. This applies to the second and third working positions not, the following as "secured position" on the one hand and "safe secured" Position "on the other hand. In these cases namely the handle hits the transmission member when it is actuated not and does not affect the lock. Inserting the key in the cylinder core and pulling it out is in the zero position possible into which the cylinder core is unlocked by its impulse spring or secured position by itself or in the safe position, in which the cylinder core after a corresponding Key turn remains.

This lock is also via a so-called "central locking device" actuated with all other in the same motor vehicle arranged closures cooperates. This central locking system includes one coaxial with the lock cylinder of each lock Central locking link, hereinafter referred to as "ZV link" shall be. The ZV link, like the cylinder core, can be rotated, but only between two positions. In the first position of the ZV limb the transmission link is moved by actuating the handle, that opens the lock. That is why this position should follow be named as "effective position". Against is in the other position the ZV link does not close the lock by actuating the handle open, which is why this position is called "ineffective position" below shall be. The twisting of the ZV link between its effective and ineffective position can be done in two ways, first by turning the key over the cylinder core.

The other way of turning the ZV link is via a central drive, the component of the central locking device provided in the motor vehicle is. Is namely a key of the cylinder core in one of those summarized in the central locking device other locks transferred from the unlocked to its secured position, this is done via the associated ZV link of the control of this central locking system reported, which then the ZV links via the central drive all other closures in the ineffective position. An actuation the ZV limbs from the ineffective position to their effective position is only possible, however, if not in the closure under consideration the safe position is present. By turning the cylinder core over a key in the other locks is the ZV link in the safe Position not in the effective position Position transferable. The safe position should be briefly below "Safe position" are called. In this safe position, the Lock neither from his handle nor via the central locking device by pressing the other locks again cancel. There is a super secured position of the ZV limb, the reminiscent of security against theft of a "safe", which is why this term used to identify the relevant position of the cylinder core becomes. When the lock is in the safe position, the actuation of the associated remains Handle ineffective and the associated lock cannot be opened. This is only possible if the associated cylinder core is keyed is returned from the safe position to the secured position. Then is by pressing the key on the other locks over the Central drive also the ZV member of the closure under consideration from a ineffective transferable to its effective position where an operation the handle opens the lock.

When this type of lock is finally turned by turning the key Cylinder core a shift cam can be moved, one to an electrical Device belonging to the vehicle, such as an anti-theft alarm system Microswitch actuated. This actuation of the microswitch takes place at least at the transition between the zero position and the secured position of the cylinder core, but advantageously also between the unlocked position and the zero position of the cylinder core, for which one is usually another Microswitch used.

The known closure mentioned in the preamble of claim 1 Art has the special feature that the locking cylinder is axially spring-loaded and at the same time serves as a "handle". The locking cylinder has an aftereffect Kind of a push button. There are of course other types of closures separate handling, but these closures are not as described above special structure according to the preamble of claim 1. The well-known closure acts after rotation of the cylinder core in the unlocked position, by pushing the locking cylinder over the ZV link to the transmission link used to open the lock. Here is the transmission member as one in an axial plane of the lock cylinder pivotable angle lever formed. Meets in effective position the ZV link when the locking cylinder is pressed, the transmission link, but not with the ineffective position. The safe position exists in the known closure in that the ZV member in its ineffective Position is blocked and therefore, as in the secured position of the cylinder core, when the locking cylinder is pressed acts on the transmission link, but on the other hand goes into nothing. The known closure of this type has numerous disadvantages.

First of all in the connection to the central drive of the known Lock the blockage of the ZV limb in the safe position of the associated one Locking cylinder must be observed. If with the other closures this central locking device by turning the key of the cylinder cores rotated and therefore the ZV links there can be moved as well the common central drive does not affect the blocked ZV link of the act in the safe position. That requires in the known closure special control means in the central locking device. In addition, there is an additional construction effort in the mechanics of the lock is necessary because the pulse spring in the safe position must be decoupled from the cylinder core. As mentioned at the beginning, is namely the key not only in the zero position, but also in the safe position can be pulled out of the cylinder core. Because of that the cylinder core must be in the safe position from its restoring effect Pulse spring can be separated. Another big disadvantage of the known Closure is that contradictory control commands arise, when the key quickly returns the cylinder core from its safe position is transferred to the unlocked position and again the secured one Position goes through. The switching cam that can be moved by the cylinder core therefore undesirably acts again on the microswitch mentioned and switches the anti-theft alarm system on again, even if the rotation continues in the unlocked position of the cylinder core of the switching cams Switch off the anti-theft alarm system via another microswitch should. This requires intelligent components in the control of the electronics. Additional components are therefore required which are space-consuming.

The invention has for its object a reliable, space-saving Develop closure of the type mentioned in the preamble of claim 1 that gets by with as few components as possible and one turn of the cylinder core between the zero position in the aforementioned three working positions and the ZV link between its effective and ineffective position allows, without tax problems with the from Cylinder core with moving switching cams result. This is according to the invention achieved by the measures listed in the characterizing part of claim 1, which have the following special meaning.

Because the control element is in the safe position of the cylinder core in a decoupling level located where it is uncoupled from the cylinder core, and the pulse spring acts only on the control member, additional locking members dispensable, the pulse spring from the cylinder core when in the safe position should decouple. There can also be no contradicting control commands get to the central locking device because, starting from the safe position, because of the control element lying in the decoupling level, the switching cam provided on the control element is at a free distance to the microswitch. The control element is indeed with its switch cam automatically moved back to a normal position by the pulse spring, which corresponds to the zero position of the cylinder core, but leaves the microswitch not activated. The cylinder core will have the proper key again from the safe position via the secured position to the zero position fed back, he needs the control element provided with the switching cam no longer to move back, this is already in its normal position aligned with it. In the zero position of the cylinder core a coupling with the control element occurs again automatically, because that Control member back into its due to the spring load acting on it Coupling level is moved back. When turning the cylinder core further the control element then moves back into the unlocked position his clutch level and can with his switch cam press another microswitch, which then clearly the electrical device reversed the vehicle and z. B. the anti-theft alarm system again ineffective.

The ZV link of the closure can also be in the safe position of the cylinder core from the central drive of the central locking device without further notice be shifted between its effective and ineffective position, because in this case there is free passage between the ZV link and the lying in the uncoupling level, but already in the normal position located control member is present. As desired, it will be in the safe position of the closure by the clearance ensures that this closure via the central locking device not into an unlocked again Position can be returned where opening the shutter over the associated handle would be possible. The central locking device too has a simple structure in the invention.

The closure comprises a handle 10 which can be seen in FIG a grip plate 13 which is useful for attacking the human hand in regions, the opening of a trough 12 recognizable from FIG. 1 in one Handle housing 11 closes. Protrudes on the back, through an outbreak, the handle with a working arm 14 on the back of the housing 11 in order to be able to cooperate with a transmission member 20, that in the first embodiment of FIGS. 1 to 6 from two levers 21, 22 is composed. The handle 10 is on one on the handle housing 11 attached shaft 15 mounted tiltable. The shaft 15 runs here essentially perpendicular to the cylinder axis 30 of one to be described in more detail Lock cylinder of this lock. By one not closer shown return spring, the handle 10 in its shown in Fig. 1 Starting position held. In this starting position, the aforementioned handle plate is located 13 in the trough opening on the front side of the handle housing, which cannot be seen in FIG. 1 because of the rear view of the closure is. 8 is the handle housing for clarity 11 omitted.

In addition, in this figure as in the other FIGS. 7 to 16b Closure shown schematically, in a simplified form. This simplification consists in Figs. 7 and 8 compared to the actual training of the closure in Fig. 1 to 6 already in that there the two levers 21, 22 of the aforementioned transmission member 20 not lying one above the other, but flat, shown side by side in the drawing plane, to better illustrate the mode of action. While the Fig. 8 shows a top view of some components of the closure, partly in the cutout, 7 is a partially sectioned front view of these components shown from Fig. 8, along the jumped section line VII-VII of Fig. 8. This makes the handle plate 13 invisible in Fig. 7 and therefore only indicated by dash-dotted lines. By grasping the handle plate with the human hand, as shown in Fig. 1, will tilt 1 and 7 around the housing shaft 15 in the direction of the arrows 16, the one on the working arm 14 acting against the aforementioned return spring Downward movement of the handle 14 in the sense of what can be seen in FIGS. 7 and 1 Arrow 17 generated. The lever 21 is normally in one aligned with the downward movement arrow 17, in Fig. 1 and also in the diagram of Fig. 8 dash-dotted plane 23, the following for short "alignment level" should be called. Then is the lever 21 in the drawn in Fig. 8 position.

As can be seen from FIGS. 1 and 8, the two levers 21, 22 are over a pivot bearing 24 is mounted together on a closure housing 31, which is assembled with the handle housing 11 described above. The pivot bearing 24 thus determines a pivot axis for the from two levers 21, 22 formed transmission member 20, the location 24 also is illustrated in Fig. 7. The aforementioned downward movement 17 leads the working arm 14 in Fig. 7 in the dash-dotted downward position 14 'and normally moves the lever 21 into its pivoted position 21' of Fig. 7. This is connected to it via a swivel 25 other levers 22 taken and into the upward pivoting position shown in FIG. 7 22 'transferred. So there is a by the arrow in Fig. 7 and 8 illustrate pivoting movement 26 of the transmission member 20, 7 in the drawing plane of each other stretched levers 21, 22. This pivot plane is the one described above Alignment level 23, which, if you look at the concrete realization of the closure of Fig. 1, as evidenced by the pivoting arrow there 26, in a radial plane to the cylinder axis already mentioned 30 runs. Evidence of the tilting arrow 16 is the direction of actuation the handle 10, however, essentially in a parallel plane arranged to the cylinder axis 30. The lever 22 engages as if the arrow 18 in Fig. 1 is illustrated, a linkage one not shown lock, which is normally the one provided with the closure Door holds in closed position. 7 and 8, this attack 18 is through a tie rod clarifies.

The closed position of the lock is when the handle 10 is not actuated in front. Then the transmission member 20 is in its recognizable from FIG. 1 Pivotal position, which in Fig. 7 and 8 by the solid lines the lever 21, 22 is illustrated. This initial position of the transmission link 20 is secured by a return spring 19, which in the present case is stretched between the lever 22 and the lock housing 31. The pivoted lever 22 is hereinafter referred to briefly as "lever" and the other lever 21 which can be actuated by the handle as a "swivel lever" be designated. These two levers 21, 22 are in Fig. 5 and 6 in Exploded view with its pin determining the swivel 25 clarifies. The two levers 21, 22 are otherwise by a torsion spring 27 held in the alignment plane 23 described above, d. H. in which 1 brought together in a contact position and in the simplified diagram of FIGS. 7 and 8 in the extended position to each other held. By actuating 16 the handle 10 is about the pivot 26 of the transmission member 20, the lock on the pull rod 18 in the open position transferred. Then a door or tailgate with the lock can be fitted open the vehicle. However, this is only possible if the locking cylinder already mentioned and to be described in more detail its zero position caused by a pulse spring over a previous so-called has reached "unlocked position" and not via the "secured position" Position "or even in the safe position already mentioned at the beginning located.

The complete lock cylinder comprises a cylindrical part 32 of the lock housing, which is to be called "cylinder housing" below. The cylinder housing 32 also determines the cylinder axis 30 mentioned. The numerous from FIG. 2 can be seen in or on the cylinder housing 32 Components arranged, to which in any case by a proper Keys 34 include rotatable cylinder core 33 and a control member 40. The cylinder core 33 has the usual spring-loaded tumblers 36, which can only be seen in the special embodiment of FIG. 13b and due to their spring load, without a key, normally protrude into blocking channels 37, likewise evident from FIG. 13b. In the simplest In this case, the blocking channels 37 are integrated directly into the cylinder housing 32, but in the present case 2 and 13b show, therefor an axially fixed in the cylinder housing 32, but rotatably mounted channel sleeve 38 is used. Next to the duct sleeve 38, a sliding ring 39 is also provided, which in the cylinder housing 32 is axially movable, but is non-rotatably. The components 38, 39, 40 are on the corresponding radially offset sections of the Cylinder core 33 pushed, to which then another as a torsion spring trained pulse-compression spring 46 comes. A lock washer 47 which engages in an annular groove at the inner end of the cylinder core 33 holds the components 33, 38, 39, 40, 46 together and ensures that by the impulse-compression spring 46, the control member 40 with a clutch receptacle 45 in the sense of force arrow 43 against a coupling projection 35 of the Cylinder core 33 is pressed and normally these two parts in Engagement holds. In the present case, the coupling projections 35 and the coupling seats 45 double, in a diametrical position to each other provided on components 33 and 40, respectively.

In Fig. 1 is the lock washer mounted at the inner end of the cylinder core 33 47 inside the cylinder housing 32 from the breech housing 31 recognizable. The cylindrical part of the control member 40 cannot be seen, but only two radially running, diametrically opposed to each other Lifting cams 41, 41 ', which represent one component of control means, which ensure an axial stroke of the control member 40. One lifting cam 41 is radially extended and carries a switching cam 42 there two microswitches 50, 50 'shown in the diagram of FIG. 10b. The two Microswitches 50, 50 'are located at the assembly points marked 52, 52' 4 in the peripheral region at the inner end of the cylinder housing 32. They are in the illustration omitted from Fig. 1 and in the axial zone next to that also there Dashed cam 42 to think. At the inside of the Cylinder housing 32 are located because of the double lifting cams 41 also double housing-fixed axial control curves 51, but of which in 1 and 4 only the one cam 51 shown and the other broken away is.

The above-described pulse-compression spring 46, which already mentioned in Fig. 2 by the arrow 43 axial force on the control member 40 in the sense of engagement of the clutch 35, 45 between the control member 40 and exercises the cylinder core 33, presses the lifting cam 41 against hers Control curve 51. The pulse-compression spring 46 is, as already mentioned was also a torsion spring, which the control member 40 with its switching cam 42 holds in a defined normal position according to FIG. 1. This normal position is also drawn out in the diagram of FIG. 10b to be described in more detail drawn. This is provided on the pulse pressure spring 46 Spring legs 48, 49, of which one 48 is on one flank 58 of one lifting cam 41 supports, while the other spring leg 49 is fixed to the housing and in the embodiment of FIG. 2 with the flank 59 of a non-rotatably mounted in the cylinder housing 32, already mentioned sliding ring 39 cooperates.

Take on a special function on the two lifting cams 41, 41 ' provided lateral stop surfaces 44, 44 'in connection with a at the inner end of the cylinder housing ZV link 60 rotatably mounted Central locking device, not shown, which in Fig. 1 in the installed state and in Fig. 3 can be seen as an individual part. The ZV link is with a hinge point 61 to the central drive of the central locking device connected and between the effective shown in Fig. 1 Position 60 and an ineffective position to be explained in more detail 60 'adjustable. The ZV link 60 has two end stops 64, 64 ' assigned to the two abovementioned stops 44, 44 'of the control element 40 and at an angular distance 62 that can be seen from FIG. 3 to one another are arranged, the angular distance between the effective and ineffective Correspond to the position of the ZV link. The ZV link 60 finally has a guide curve 63 with one on the pivot lever 21 of the transmission member 20 provided guide edge 53 cooperates. In concrete terms The embodiment of FIGS. 3 and 6 is the axial slope in the guide curve 63 provided while the cooperating leading edge 53 of the bell crank 22 can be substantially flat. The resulting resulting control is from the simplified scheme in Figs. 7 through 12b clarifies.

The simplification in the diagram of Fig. 7 to 12b is initially how has already been mentioned in that the lever shown in Figs. 7 to 9 21, 22 not in the contact position, as shown in Fig. 1, but in the extended position are. A further simplification is that in FIGS. 10b to 15b, the rotatable control member 40 is shown as a flat slide is that under the restoring effect of the schematically shown here Spring 46 stands. The pressure effect illustrated in FIG. 1 by arrow 43 the above-described pulse-compression spring 46 also plays a role in the diagram Role. So you can see the representation in the scheme as a flat development of the cylindrical control member 40 of Fig. 1 and 2 indicate. Finally is in the schematic drawings of Fig. 8 to 12b that the concrete Execution of the closure shown in Fig. 1 and 3 ZV link 60 as a movable slide shown in the plane of the drawing and its axially fixed Rotary bearing on the inner end of the cylinder housing 32 by a simple Slide guide 65 in the lock housing 31 illustrates from which the ZV link 60, as shown in FIG. 10b, with its for connecting the central drive serving joint 61 protrudes. In Fig. 10b are also still the microswitches 50, 50 'not recognizable in FIG. 1 on the previously described ones Assembly points 52, 52 'of the closure housing 31 are shown schematically, together with their to be controlled by the switching cam 42 of the control member 40 Switching elements 55, 55 '. The two microswitches 50, 50 'are in the electrical Anti-theft alarm circuit switched on.

In the scheme shown in Figs. 8 and 9, the axial slope is between the guide curve 63 belonging to the ZV link 60 on the one hand and the leading edge 53 belonging to the pivot lever 21 with respect to the specific one Embodiment of Figures 1 to 6 have been interchanged; in Fig. 8 the leading edge 53 of the lever 21 the whole slope, while the guiding curve 63 of the ZV link only shown in fragments there is illustrated as the tip of a finger, which also applies to the following 9 to 12b of the scheme applies. Despite their different shape, they should but those introduced in the specific embodiment of FIGS. 1 to 6 Terms can also be used in the diagram of FIGS. 7 to 12b.

10a shows a front view of the cylinder core 33 in its zero position, by an auxiliary line determined by the position of the key channel 28 70 is made clear. The position of the components in this zero position is 70 drawn in full in the diagram of Fig. 10b. About his impulse pressure spring 46, the control member 40 is normally already in its top mentioned normal position held, drawn in Fig. 10b drawn is. The switch cam provided on it is in this normal position 42 in a neutral position between the two microswitches 50, 50 '. The pulse-compression spring 46 ensures that the above-described is engaged Coupling 45, 35 also for a defined position of the cylinder core 33, which, as can be seen from FIG. 10b, is straight out of it 10a recognizable zero position 70 is held.

In Fig. 10b, the ZV link 60 is in its previously described effective Position that is non-positively fixed by locking elements 63, 56, 56 ' can be. These locking elements are in the concrete execution of 1 to 6 not shown. In Fig. 10b these locking elements are through an elastic grid elevation 66 indicated on the ZV link 60 and one the raster elevation 66 receiving the first latching depression in this case 56 illustrated in the closure housing 31.

10a are two working positions 71 on both sides of the zero position 70, 72 of the cylinder core 33, which is shown by rotation of the in the cylinder channel 28 stuck key in the sense of the two opposite to each other Arrows 75, 75 'can be achieved relative to the zero position 70. In the Rotation 75 of the cylinder core 33 to the first working position 71 from 10a is also the control member via the engaged clutch 35, 45 40 taken and comes from the drawn in Fig. 10b drawn Normal position 40 in the first working position indicated by dash-dotted lines 40 '. This also causes the switching cam 42 to move out of its normal position the first working position 42 ', also indicated by dash-dotted lines and actuates the switching element 55 of the microswitch 50, which then switches on the mentioned anti-theft alarm system. At the same time takes the control member in its first working position when it moves 40 'over the abutment surface 44 described above also the ZV link over its end stop 64 with, so that this from its effective position 60 into the ineffective one, which is also shown in broken lines in FIG. 10b Postion 60 'is transferred. This ineffective position 60 'of the ZV link is also fixed by locking elements, because the above-mentioned grid elevation 66 in a correspondingly offset latching recess 56 'of the closure housing 31 engages. Accordingly, there is an offset of the guide curve 63 into the one indicated by dash-dotted lines in FIG. 10b Position 63 '.

These relationships are also illustrated in the diagram in FIG. 8. There the position of the guide curve in its offset position 63 'is also the same indicated by dash-dotted lines. The guide curve travels in this offset position 63 'against the leading edge 53 of the pivot lever 21 and rotated this with respect to the described hinge 25, according to the rotating arrow 57, in the angular position 21 ", which is also indicated by dash-dotted lines in FIG. 8; the angle lever is from the alignment plane 23 described in one Angle plane 23 "transferred. The angled pivot lever 21" is now no longer in alignment with the working arm 14 of FIG. 8, which is why its downward movement described in connection with FIG. 7 in the sense of arrow 17 no longer hits the pivot lever 21 ". An actuation 16 of the handle 10 according to FIG. 1 is therefore ineffective. In the concrete 1, the pivot lever 21 arrives from its position there Alignment plane 23 also shown, already described, into the where the angled plane 23 "is drawn in analogously, where it is to the deflection lever 22 runs angled and no longer with the working arm 14 of the handle 10 is aligned. The bell crank 22 remains, despite actuation the handle 10, at rest. This turns out to be the first working position 71 of the cylinder core 33 from FIG. 10a as the "secured" described at the beginning Position "of the cylinder core 33.

If you let go of the key after reaching the secured position 71, so first the pulse-compression spring 46 also executes the control member its first working position 40 'again in the normal position drawn in solid lines 40 of Fig. 10b back. Because of the still engaged Coupling 45, 35 is also the cylinder core 33 indirectly, via the Control element 40, again in the normal position shown in extended form in FIG. 10b returned. The stop surface 44 on the control member is now moving 40 also return to their normal position from FIG. 10b, but the ZV link remains in its ineffective position 60 ', where it is caused by the engaged locking elements 56, 66 of Fig. 10b is held. This means that the pivot lever in its angled position 21 " remains and the handle 10 is idle to the transmission member 20 is located.

That only changes again when the cylinder core 33 has the key, 10a, in the direction of the opposite arrow 75 to the zero position 70 in a second working position 72 is transferred. About that too in this If the clutch 35, 45 is engaged, the control member is also off its zero position 70 from Fig. 10b in the dotted there second working position 40 "transferred. At the transition to this second working position 72 comes the control member with his switch cam in the 42 "in Fig. 10b designated second working position. This is the switching element 55 'of the second microswitch 50' operated, the anti-theft alarm system switches off again. The ZV link was in its previously described ineffective position 60 ', so was his other stop surface 44 ', as shown by dash-dotted lines in Fig. 10b, at the end stop 64' from ZV link. Therefore, the key rotation 75 'of Fig. 10a over 44 ', 64' also the ZV member from its previous ineffective Position 60 'again in the drawn effective position 60 returned. The leadership curve comes back into the stripped in Fig. 8 drawn effective position 63, whereby the previously angled Swivel lever 21 "via the torsion spring 27 back to its starting position 21 arrives in the alignment plane 23 of FIGS. 8 and 1. The castle is thus open again by operating the handle 10. This working position 72 thus proves to be the "unlocked position" mentioned at the beginning of the closure. Leave the key again after the turn 75 ' is going on, the pulse pressure spring 46 and the control member the clutch 45, 35 also the cylinder core 33 back to its zero position 70 returned.

11a, the cylinder core 33 is again shown in front view, but in a secured position 71 because of the above the limit position marked 73 from the larger rotary arrow 76, in which, as can be seen from the diagram which is illustrated analogously to FIG. 11b, the limbs of the closure are in a borderline situation. The control link 40 was transferred to its limit position 40 "' axial control means between the closure housing 31 and the control member 40 effective. In the specific exemplary embodiment according to FIGS. 1 to 6 the two lifting cams 41, 41 'run from the control member 40 onto the two associated control curves 51 from the cylinder housing 32 in FIG. 4. This are illustrated in the diagram according to FIGS. 10b to 15b by inclined surfaces 51, 41. 11a in the limit position of the cylinder core 33 11b, the lifting cam 41 extends as far along the housing side Control curve 51 moved up. That is in Fig. 11b by the axial Lift arrow 77 illustrates. Between the axially fixed position of the ZV link 60 and the axially movable control member 40 is sufficient Game so that this stroke movement 77 of the control member 40 from the ZV link 60 is not hindered.

The coupling projection has itself due to this lifting movement 77 of the control member 40 ″ 35 of the axially fixed cylinder core 33 from the coupling receptacle 45 of the axially moving control member almost uncoupled. If you turn 11a, the cylinder core 33 in the sense 12a to a third working position 74 continue with the key, so when the limit position is exceeded 73, a decoupling between the coupling projection 35 and the coupling receptacle 45 a. The control member moved up to the limit position 40 "' is now free and, as shown in FIG. 12b, becomes effective the pulse pressure spring 46 is returned to its normal position 40, however, the axial stroke 77 is retained for the following reason.

As already said and illustrated by the force arrow 43 from FIG. 2 was, in the concrete closure according to FIGS. 1 to 6, the pulse-compression spring 46 also one indicated by the force arrow 43 there Pressure effect, which is also shown in the diagram of Fig. 11b and 12b is. In FIG. 11b, the control element is raised up to the limit position 40 "' against the action of this force 43 in the sense of the lifting arrow 77 This force 43 remains uncoupled even in the normal position 40 achieved 12b, but the control is now supported 40 axially on the coupling projection 35 of the axially fixed but rotatable in the housing 31 stored end surface of the cylinder core 33. The control link 40 is now in Fig. 12b in one of the height of the coupling projection 35 determined decoupling level 67. This is compared to the preceding coupling plane 69, which in both Fig. 12b and in Fig. 10a is drawn to the axial distance 68 compared to the original Level 69 offset. That is why the control element is in the normal position 40 in Fig. 12b additionally labeled "Safe" to keep them from the normal position 40 to be distinguished in the coupling plane 69 from Fig. 10b. This The term "safe" is explained in more detail.

At the transition from the limit position 73 with that shown in FIG. 11b Position of the limbs in the third working position shown in FIG. 12a 74 of the cylinder core 32 are special conditions. Already in the Limit position 40 "'of Fig. 11b has the switching cam 42"' in one axial distance 68 to the switching element 55 of the microswitch 50 moves, which is why when the switching element is later returned to the normal position 40 "Safe" from FIG. 12b, the movement in the uncoupling plane 67 takes place. The switch cam thus achieves its normal position shown in FIG. 11b 42 in a corresponding axial distance 68, which is due to the height difference between the two levels 67, 69 is determined, which is also the case in FIG. 12b is labeled "Safe". The cam 42 moves again Microswitch 50 returns to its normal "safe" position, but at a clear distance 68 without actuation of the switching element 55 by the microswitch 50. The preceding the switch-on took place during the transition to the secured position 71 the anti-theft alarm system is retained and the microswitch 50 is not pressed again.

As can be seen from Fig. 12b, there is another peculiarity of the closure at the ZV link. There is initially related by the 10b transition described in the secured position 71 of Cylinder core 33 transfers the ZV link into its ineffective position 60 ' which, when turning 76 further, both in the limit position of FIG. 11b and even more so in the third working position of FIG. 12b becomes. Although now again, but in the uncoupling level 67, the normal position 40 "safe" of the control element is located - through the key rotation 76 of FIG. 12a is unaffected - the ZV link always still in its ineffective position 60 '. This is because that too the stop surface 44 'moves back from the control member in Fig. 12b has, but the associated end stop 64 'of the ineffective ZV link 60 'could not move. The ZV link remains ineffective Position 60 ', where its grid elevation 66 resiliently in this position characteristic engaging recess 56 'engages. The ZV link can on his Attack point 61 from the drive of the central locking device Pressing another key belonging to this system without further be transferred to its effective position 60. In Fig. 12b is the reversal path 78 of the ZV link from its ineffective position 60 'is drawn into its effective position 60, which is illustrated by dash-dotted lines. This reversal movement does not affect a switching movement of the two microswitches 50, 50 '. The control member remains at rest, namely in its normal position 40 "Safe" from Fig. 12b.

The third working position 74 of the cylinder core 33 thus proves to be the aforementioned super-secure position of the lock, wherever the present lock on the other locking cylinders of this system cannot be transferred to its unlocked position. It's located in Fig. 12b the "safe position" before, but with the special feature that here there is no blockade, but the extent of the ZV limb is released of the required reversal route 78 between the two positions 60, 60 'is generated.

The angular position can also be manipulated in the safe position Do not change 21 "of the swivel lever from level 23". It occurs even an additional safe security, as shown in FIG. 9 can be seen. Fig. 9 shows, but in solid lines, in Fig. 8 dash-dotted angle position 21 "of the pivot lever compared to the one that remains unchanged in its swivel plane Deflection lever 22. Drawn out, the ineffective position 63 ' the guide curve, which moves the swivel lever into the described plane 23 ". In safe position 74 of the cylinder core 33 of FIG. 12a and the associated FIG. 12b is, as has been described, the control member located in normal position 40 around the axial distance 68 has been lifted from the cylinder core 33. That is why one is on the control link 40 of Fig. 2 provided pushing surface 54 axially pushed out. This Bump surface 54 from control member 40 is illustrated in FIG. 9 as a finger and shown in this safe position. As can be seen, now comes too the abutment surface 54 on the angled pivot lever 21 "for contact and secures it in its angled plane 23 ". Now, as with the reversing path 78 of FIG. 12b has already been discussed, the ZV link pushed back into its effective position 60, which means its Guide curve 63 releases the angled pivot lever 21 " this does not reset the pivoting lever from the angle of deflection 23 "in its alignment plane 23 from FIG. 9; the abutting surface 54 holds the pivot lever 21 "in its angled plane 23". It stays still, despite possible adjustment 63, 63 'of those belonging to the ZV link Guideway in safe position the associated handle 10 this Closure ineffective.

This exists in the specific embodiment of the closure according to FIG. 2 Butt surface 54 from a substantially flat end surface of the one lifting cam 41. Presses at the axial stroke 77 explained with reference to FIG. 11b the lifting cam 41 with its abutting surface 54, which is indicated by dashed lines in FIG. 6 Butt edge 53 'away from the pivot lever 21 and holds it, by analogy 9, in the angled plane 23 "shown in FIG. 1.

13a shows the cylinder core 33 in its safe position 74 and in FIG. 13b therefore the associated control element in the decoupling plane 67 in its Normal position 40. The conditions are therefore the same as in Scheme of Fig. 12b. The difference is that in 13b also the mode of operation of the already in connection with FIG. 2 explained components 38, 39 is shown. 13b to 16b show one So-called overload protection on the locking cylinder 33. The sliding ring 39 is, for example by radial lugs 29, in corresponding longitudinal grooves 79 of the closure housing 31 is axially movable, but non-rotatably guided, what was mentioned above. As already mentioned, is the duct sleeve 38 although axially fixed but rotatable in the closure housing 31. The overload protection consists first of all in that the sliding ring 39 and the channel sleeve 38 to each other on their mutually facing end faces have complementary lifting profile 81, 82. This exists, as well can be seen from Fig. 2, from an approximately trapezoidal recess 82 in the channel sleeve 38 and a complementary elevation 81 in the sliding ring 39. As shown in FIG. 2, two are expediently to one another diametrical lifting profiles 81, 82 of this type are provided. As another component this overload protection, a compression spring 80 is provided which z. B. is supported on the mentioned radial lugs 29 of the sliding ring 39 and spring-loaded in the direction of arrow 83 of FIG. 14b. As long as not the proper key in key channel 28 of Fig. 13a 13b, grips the tumblers already mentioned 36 in the locking channel 37 of the channel sleeve 38 and thus ensure a non-rotatable connection between the cylinder core 33 and the channel sleeve 38.

If the cylinder core 33 is not replaced by the correct key, but rotated by a burglary tool in the direction of arrow 86, so the channel sleeve 38 is also rotated via the engaging tumblers 36 and therefore, when a certain limit load is exceeded, the lifting profile 81, 82 raised against the spring force 83 of the compression spring 80. This Situation is shown in Fig. 14b. Now the sliding ring 39 supports it Control member 40 with its end face opposite the lifting profile 81 89. As a result, the control member 40 remains unchanged even in the event of a break-in in its normal position 40, already apparent from FIG. 13b, in the decoupling plane 67 held, but not only over the coupling projection 35 from the cylinder core 33, but also from this end face 89 of the Slider rings 39. The safe position thus remains ensured even in the event of a break-in. As shown in FIG. 14 a, the cylinder core 33 can be removed from the break-in tool be rotated according to the rotation case 86 without the ineffectiveness the handling operation is eliminated; the castle remains still closed.

15b to 16b show further measures of the overload protection described above. The channel sleeve 38 is provided here with an opening 84, which is penetrated by a synchronization element embodied here as a roller 85 becomes. The closure housing 31 has a first recess here 87 for one end of the roller 85 and the peripheral surface of the cylinder core 33 a second recess 88 for the opposite end of the roller 85. In the safe position 74 of the cylinder core illustrated in FIG. 15a result from a violent rotation 86 using a burglary tool the ratios shown in cross-section in Fig. 16b at the location marked XVIb-XVIb in FIG. 15b. Is, as already was said in connection with FIG. 14b, the cylinder core 33 over the engaging tumblers are connected in a rotationally fixed manner to the channel sleeve 38, so these parts, as the rotation arrow 86 of FIG. 16b illustrates, shot together. The roller 85 leaves the recess on the housing side 87 and moves fully into the core-side recess 88.

16a shows the situation at the same point as FIG. 16b, if the relationships explained in connection with FIGS. 10b to 12b exist where the cylinder core 33 has a proper key is twisted. In this case, those in connection with Fig. 13b tumblers 36 on the circumference of the cylinder core which have already been described several times 33 sorted and is rotatable with respect to the channel sleeve 38. This ensures roll 85. It now moves into the housing-side recess 87, but is still reaching sufficiently for the breakthrough 84 a to the channel sleeve 38 rotatably relative to the closure housing 31 to secure. The roller 85 gives the other recess 88 in FIG. 16a free and therefore leaves the above-described rotation 76 of the cylinder core 33 compared to its channel sleeve 38.

17 to 22 is a second concrete embodiment of the invention Shutter shown that in many ways similar to that Structure and operation of the previous first embodiment 1 to 6, which is why the previous description applies. The same reference numerals are used to designate analog components as used in the first embodiment. It is enough just to address the differences.

The main difference compared to this second embodiment the first is that here the transmission link does not consist of two Lever, but consists of a single combination lever 90, the Appearance is best seen in Fig. 18. The associated housing 31 has a ball joint for the combination lever 90, for which z. B. 17 a ball head 91 and the combination lever 90 of FIG. 18 have a ball socket 92. The cohesion of this Components can be secured by a tension spring 93. There is a defined one Starting position of the combination lever 90, which in the extended in the schematic FIGS. 20, 21, 22 is illustrated and again an alignment level indicated by dash-dotted lines in these figures 23 determined. The combination lever 90 has one shown in FIG. 18 Shoulder 94, on which in the alignment plane 23 the one illustrated in FIG. 18 Working arm 14 when operating the handle in the direction of the arrow 17 hits. In this case, the one shown by arrow 26 comes again Swiveling movement of the combination lever 90 occurs. The combination lever 90 takes with it a rod 18 leading to the lock, which at one special attack point 95 provided on it is attached.

This attachment is carried out by, as shown in FIGS. 18 and 22, on Combination member 90 provided arcuate tab 95, the one Has slot 96. This slot 96 is one of a pin 97 Link 98 penetrates positively, when pivoting 29 of the combination lever 90 takes the rod 18 and thereby Lock opens. In Fig. 18, the link 98 is opposite the tab 95 shown in the uncoupled position. With this pivoting 26 plays an axle pin 101 a roller, which in a laterally open receptacle 99 engages in the housing shown in FIG. 17 and also in FIGS. 20 and 21 is illustrated. This receptacle 99 practically consists of a U-hook, whose hook opening forms the receptacle 99. In the initial case, 20, the axis pin 101 is in axial alignment with the ball joint 91, which is dash-dotted in Fig. 20 in coaxial Location to the axis pin 101 is drawn. Through the tension spring 93 Axle pin 101 pressed in the bottom of the hook-shaped receptacle 99 held. When pivoting over the actuated handle, the axle pin 101 on the combination lever 90 in the pivoted position indicated by dashed lines 101 'moves. Because of the tension spring 93 in FIG. 20, however, the axle pin after releasing the handle back to its original position 101 on the inside End of recording 99 returned.

Also with this closure, a ZV link 100 is provided, the appearance of which 19 and its mode of operation from the Scheme can be seen in Fig. 21. In this case, the leadership curve designed as a groove-like positive guide 103 for a guide pin 102, which, as shown in FIG. 18, is located on the combination lever 90, that is, essentially in parallel to the axis pin 101. This can also be seen from FIG. 21, where the ZV link 100 is in the extended position Lines drawn, located in its effective position. With the aforementioned Swiveling movement 26 of the combination lever 90 in the alignment plane 23, the guide pin 102 moves from the one in FIG Place the cut-out positive guide 103 radially into the dashed line there illustrated pivot position 102 ', which is also indicated in Fig. 20 is.

However, if the ZV link 100 in FIG. 21 in the sense of the arrow 104 in transferred its ineffective dash-dotted position 100 ', then the Guide pin in the position also shown in dash-dotted lines in Fig. 21 102 ". Now the guide pin 101 determines in the bottom of the receptacle 99 together with the ball joint 91 a vertical axis of rotation in FIG. 21 108, through which the combination lever 90 in the sense of the double arrow 107 transferred into its angled position 90 "indicated by dash-dotted lines becomes. Now the whole combination lever is 90 "in the in Fig. 21 illustrates the angle of deflection 23 ", where it goes from to the handle 10 belonging working arm 14 can no longer be operated as in FIG. 18 can. The combination lever is located in this angled plane 23 " 90 "with his shoulder 94 of Fig. 18 outside the path of movement 17. The combination lever 90 "can no longer be pivoted. The associated lock remains at rest.

This rotary adjustment 104 of the ZV link in FIGS. 21 and 19 can again either via the key through the cylinder core also shown in FIG. 2 33 or via the drive element of a central locking system, for which the ZV link 100 has a suitable point of attack 109. The ZV link 100 also has locking lugs 105, 106 which can be seen in FIG. 19, which it in certain rotational positions on the cylinder housing 32 of the breech housing 31 of Fig. 17 latch, as in the previous embodiment based on the latching elements 63 and 56, 56 'explained in FIG. 10b was explained. In all other respects, the situation is the same as in the first embodiment.

22 shows the meaning of the special connection described 98 on the tab 95 of the combination lever 90. Is namely the Combination lever in its angular position 90 "allows the elongated hole 96 in the backdrop 95 an undisturbed rotary movement 107 from the alignment plane 23 into the angled plane 23 ". The one leading to the lock Rod 18 remains at rest.

In this case too, the safe position is as shown in the diagram 12b has been explained, the control member 40 from the 22 drawn coupling plane 69 in the sense of the lifting arrow 77 via control curves on the housing from the dash-dotted line in FIG. 22 indicated coupling level 69 in the decoupling level also shown there 67 lifted up. In this decoupling plane 67 supports the control member at the end of the disengaged coupling projection 35 from the cylinder core 33 and can also be provided in this case Pulse compression spring 46 in the normal position indicated by dash-dotted lines in FIG. 22 40 "Safe" can be returned. The control element is now supported with its abutting surface 54 on the one in its angled position 90 " Combination lever, as indicated by "Safe" in Fig. 22. If the control member 40 is in the preceding clutch plane 69, where it is drawn in solid lines in FIG. 22, the abutment surface 54 is axial reset and therefore the combination lever 90 pulled back into his 22 rest position shown in FIG. Then the control lever 40 with the coupling projection 35 of the cylinder core 33 again in engagement. This corresponds to the initial situation explained in FIG. 10b.

Claims (15)

1. Closure for doors, bonnets, tailgates or the like, in particular of vehicles, such as motor vehicles,

   with a lock cylinder, the cylinder core (33) of which can be rotated by a proper key (34) out of a neutral position (70), determined by an impulse spring (46), into three working positions (71, 72, 74), namely a released position (72), a secured position (71) and a safe-secured position (74),

   with a handle (10), which, upon actuation in the released position (72) of the cylinder core (33), runs against a pivotably mounted (26) transmission element (20) and opens a lock associated with the transmission element (20), but in the secured position (71) and the safe-secured position (74) does not run against it and renders the lock unactuable,

   with a central locking element (60), which is rotatably mounted coaxially with the cylinder core (33) and is displaceable, both by rotation (75, 75', 76) of the cylinder core (33) by the key and by a central drive, acting (61) directly on the central locking element (60), of a central locking device, between a position (60) which is operative for the lock actuation and a position (60') which is inoperative in this regard, but in the safe-secured position (74) cannot be moved out of its inoperative position (60') into its operative position (60) by the central drive,

   and with a trip cam (42), which is carried along by the cylinder core (33) by rotation (75, 75', 76) of the key, and which, when the cylinder core (33) passes between the neutral position (70) and the secured position (71) and, where appropriate, released position (72), actuates a microswitch (50, 50') of an electrical device of the vehicle, such as a theft warning system,

   characterised

   in that a control element (40) carrying the trip cam (42) is displaceable by rotation (76) of the key, via control means (41, 41', 51), between two spaced planes (69, 67),

   namely on the one hand a coupling plane (69), in which the control element is coupled (35, 45) to the cylinder core (33) in the neutral position (70) and in the secured position (71) and released position (72),

   and on the other hand an uncoupling plane (67), into which the control element (40) comes when the cylinder core (33) passes into the safe-secured position (74), and is then uncoupled from the cylinder core (33),

   in that the impulse spring (46) is always connected to the control element (40), in order to cause the trip cam (42) to spring back into a normal position aligned with the neutral position (70) of the cylinder core (33), in both planes (69, 67), namely

   upon a small rotation (75, 75') of the key between the neutral position (70) and the secured position (71) or released position (72) in the coupling plane (69), with actuation of the microswitch (50, 50')

   but on the other hand, in the inoperative position (60') of the central locking element, pushes the rotatable part (21) of the transmission element (20) away, against the spring loading (27), into an angled plane (23'') offset from the handle and renders it non-pivotable (26),

   and in that, in the safe-secured position (74) of the cylinder core (33), the rotatable part (21) of the transmission element (20) is held in the angled plane (23'') by an abutting face (54) provided on the control element (40) even when the central locking element is moved back out of its inoperative position (60') into its operative position (60) by the central drive.
2. Closure according to Claim 1, characterised in that the control element (40) is movable (77) axially, in the direction of the cylinder axis, between its coupling and uncoupling plane (69, 67) and - in the safe-secured position (74) of the cylinder core (33) - is held in its uncoupling plane (67) against an axial spring force (43) by the uncoupled part (35).
