Abstract

The invention concerns a closure with a closure cylinder whose cylinder core (33) can be moved by a key into different operating positions. The object of the invention is for at least one microswitch (50) to be actuated by means of switching cams (42) only once, even if the switching cam (42) continues to be moved when the microswitch (50) has been actuated. During the return movement, this microswitch (50) should not be triggered by the switching cam (42) again, and so faulty switching is avoided. To that end, a control member (40) cooperates via a separable coupling (35, 45) with a control member (40) on which the switching cam (42) is located. The control member (40) is acted upon by a restoring spring (46) which endeavours to move the control member into an initial position and simultaneously subject it to a force (43) in the coupling sense by means of the cylinder core (33). By controlling the lift as it moves, the control member (40) is moved axially out of a coupling plane (69) into an uncoupling plane (67) in which it can return to its normal position (40) again under the effect of the restoring spring (46). This restoring movement in the uncoupling plane (67) occurs at a distance from the microswitch (50), such that the switching cam (42) does not actuate the microswitch (50) again.

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. The Connection between the lock and the handle is in this position set effective. This does not apply to the second and third working positions, the following as "secured position" on the one hand and "safe secured" Position "or" Safe Position "for short, on the other hand. In these cases, the handle is ineffective, which is why Actuation the lock remains at rest. Insert the key in the cylinder core and pulling out again is possible in the zero position, into which the cylinder core is unlocked by its pulse spring or secured position by itself or in the safe secured position Position in which the cylinder core after turning the key rests.

The rotation of the cylinder core from the lock to the different working positions is reported to a central locking device, the following for short "ZV facility" should be referred to. This ZV facility acts on further closures of the motor vehicle, the corresponding Controlled way. The provided with these other closures Locks are then activated in an analogous manner by the ZV facility or set ineffective. However, if the lock is in its safe position then it can be operated by key actuation of the cylinder core of the other closures via the ZV facility did not come back in an unlocked position is transferred, where an operation of the handle can open the associated lock.

A switch actuator is also moved when the cylinder core is turned, that at the transition between the zero position and the secured Position or the zero position and the unlocked position a microswitch actuated, each of the specific additional functions in the motor vehicle triggers e.g. B. causes the aforementioned control of the ZV facility or switches an electrical anti-theft alarm system on or off. If the cylinder core goes beyond the secured position into the safe position rotated further, the switch actuator moves beyond the microswitch further and is fixed in this position in the known closure. Therefore, as already mentioned, this remains in the safe position Lock belonging to the lock is blocked because the handle is ineffective. Will the cylinder core in the known closure from the safe position turned back to the zero position by the key to the zero position To be able to be pulled out again on this way back Drive through the secured position again and the switch actuator switches actuates the microswitch again. As a result, the microswitch the functions relevant to the secure position take effect again set, e.g. B. Turn on the theft alarm system, blocking the Locking and blocking the ZV facility. This can be done with the known Closure not only to unpleasant, but also to dangerous situations to lead.

A dangerous situation can arise with a crowd of vehicles Locks on the doors and on the tailgate reveal the central are controllable by a ZV facility. During the closures of the doors three working positions (zero position, secured and unlocked position) have, the closure of the tailgate is also in the already repeatedly mentioned safe position can be transferred, in which it is in the accepted Case should be. If you go through the closures on the doors Key actuation of a lock via the ZV facility in the unlocked Transferred position, the lock on the tailgate remains in the Safe position. Finally, the closure of the tailgate through the key to the zero position (but not to the unlocked Position), turned back and then the key removed, so run over the switch actuator on the rear lock is the microswitch, then the functions mentioned in the "secured position" again takes effect. This means that the ZV facility is made to to put the locks of all doors back into the "secured position". Then all doors of the vehicle are closed and any occupants in the Vehicle caught.

The further conceivable is relatively harmless, but still unpleasant Case that with an open door the rear lock from the safe position is moved back to the zero position. In this case, by Passing the microswitch by the switch actuator the anti-theft alarm system switched on and alarm triggered. This leads to unnecessary noise pollution.

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 allows three working positions without tax problems with the result from the switch actuator moving with the cylinder core. This is according to the invention by the measures listed in the characterizing part of claim 1 achieved, which have the following special meaning.

Because the control element is in the safe position of the cylinder core in a decoupling level located and thus automatically uncoupled from the cylinder core is, additional closure members are unnecessary, which is in the safe position the pulse spring should uncouple from the cylinder core. The pulse spring can always remain connected to the control element. Neither can contradicting control commands reach the ZV facility, because, starting from the safe position, because of the decoupling level lying control member, the switch actuator provided on the control member is at a clear distance from the microswitch and during its return movement ineffective passes the microswitch. The control link will with its switch actuator by the pulse spring in itself moves back to a normal position which corresponds to the zero position of the cylinder core, but leaves the microswitch inactive. Will the cylinder core with the proper key again from the safe position over the secured position returned to the zero position, so he needs it with the switch actuator provided control member no longer back move, this is already in its aligned with it Normal position. In the zero position of the cylinder core occurs automatically again a coupling with the control member because the control member through on the spring load acting on it moves back into its coupling plane becomes. Moved to the unlocked position as the cylinder core continues to rotate then the control element again in its clutch level and can operate another microswitch with its switch actuator, which then clearly reverses the electrical system of the vehicle and Z. B. sets the anti-theft alarm system ineffective again, and / or ZV facility controls.

A particularly simple construction of the closure according to the invention results itself when the axial movement of the control member between the different Levels to operate one or more microswitches, which can then take over further functions in the motor vehicle. So it is recommended to add a third microswitch in the circuit of the two turn on the aforementioned microswitch and turn it on immediately to be actuated by the control element. The control element moves out its coupling level into a decoupling level or another level, the third microswitch can interrupt the entire electrical circuit. This results in a particularly high level of security against burglary with one equipped with this lock. It also will the "safe position" or a "workshop position" with the key reached the lock set on the cylinder core.

As can be seen from Fig. 1 to 6, there is a lock cylinder in a cylindrical part 32 of the closure housing, which follows "Cylinder housing" should be named. The cylinder housing 32 determines also the cylinder axis 30 referred to in this description with the word "axial" is referred to. In or on the cylinder housing 32 are the numerous recognizable from Fig. 5 arranged components, to which in each Case of the cylinder core rotatable by a proper key 34 33 and a control member 40 belong. The cylinder core 33 has the usual spring-loaded tumblers 36, which are only in Fig. 11b with their ends are recognizable and due to their spring load, without a key, with their ends in blocking channels likewise evident from FIG. 11b 37 protrude. In the simplest case, the blocking channels 37 are directly in the cylinder housing 32 is integrated, but for reasons that will be mentioned later in the present case, as shown in FIGS. 5 and 11b, there is one in the cylinder housing 32 used axially fixed, but rotatably mounted channel sleeve 38. In addition to the channel sleeve 38, a sliding ring 39 is also provided, which is axially movable but non-rotatably mounted in the cylinder housing 32 is.

The components 38, 39, 40 are on radially offset sections of the Cylinder core 33 pushed, to which then another as a torsion spring trained pulse-compression spring 46 comes. The pulse pressure spring 46 also acts as a compression spring, for which it has a helical section owns. This helical section of the spring 46 engages around a cylinder extension 27 on the control member 40. The two legs 48, 49 of the spring 46 hold both a finger 26 of the control member 40 between them also a finger fixed to the housing 21. As a result, the cylinder core 33 held with its key channel 28 in a specific zero position 70, which is indicated in Fig. 3 by a vertical line. By introducing a proper, proper key 34 into a key channel 28 of the cylinder core 33, this can optionally in the further from Fig. 3 apparent working positions 72, 73, 74 are transferred, what else will be described in more detail.

The finger 21 fixed to the housing belongs to a further housing part 20, which is firmly connected to the cylinder housing 32 and its formation can be seen from Fig. 6. This housing part 20 has a bearing 22 for the pivot pin of a working member 18, which has a pull rod 17 or the like. Mechanically connected to a lock 19 indicated in FIG. 7 is, which is usually electrically operated. This mechanical In this exemplary embodiment, components 17, 18 should only be used in an emergency be effective.

A lock washer 47, which is in an annular groove at the inner end of the cylinder core 33 engages, holds the components 33, 38, 39, 40, 46 together and ensures that the control member 40 with the pulse-compression spring 46 a coupling receptacle 45 recognizable from FIG. 1 in the sense of the force arrow 43 pressed against a coupling projection 35 of the cylinder core 33 and usually keeps these two parts engaged. In the present Case, the coupling projections 35 and the coupling receptacles 45 are double, Provided in diametrical position on the components 33 and 40, respectively. These coupling parts 35, 45 serve the purpose shown in FIG. 3 Key rotations 75, 75 ', 76, 76' of the cylinder core 33 on the control member 40 to transfer.

In the specific exemplary embodiment, these coupling parts 35, 45 still have an additional function; because they have a special profile that it enables a stroke control of the control member 40, which is based on the 8c to 10c will be explained in more detail later. 8a to 13b are the ratios in a modified second Embodiment shown. 8a to 13b have the coupling parts 35, 45 a simple rectangular profile. The aforementioned lift control is in these figures as a stationary control surface 51 on the housing 31 on the one hand and a lifting surface 41 on the one shown here in a flat development Control member 40 realized on the other hand. This will be discussed in more detail.

In the embodiment of FIGS. 1 to 6, three microswitches are in the housing part 20 50, 50 ', 50 "integrated and thus in a defined manner opposite the control member 40 positioned. In the simplified schematic representation from Fig. 8a to 13b and also in the aforementioned alternative 8c To 10c, these microswitches 50, 50 ', 50 "are shown schematically in the closure housing 31 have been drawn. The associated switching elements are also there 55, 55 ', 55 "for each of these microswitches 50 to 50" separately drawn. In the specific exemplary embodiment, two of these microswitches, namely the first 50 and the second 50 'to a combination switch 53 summarized, switched by a common actuator 54 becomes. This actuator 54 is in the sense of the double arrow 56 of Fig. 6 pivotable. When swiveling in one direction becomes the first microswitch 50 and when pivoted in the opposite direction the other switch 50 'switched.

The control element 40 serves to actuate all three switches 50 to 50 ". For this purpose, a switching cam is shown in the schematic representations of FIGS. 8a to 13b 42 is provided on the control member 40, which is in different positions 42 ' to 42 "'can be transferred, which is explained in more detail. In concrete Exemplary embodiments are for the described pivoting movement 56 of the common actuator 54 from the combination switch 53 two 5 evident switching edges 61, 62 are provided, which function of such a switch cam. The switching element 55 "of the third Microswitch 50 "interacts directly with the control element 40, with the axial end surface 60 of a flange-like part. This Switching effectiveness of the control member end surface 60 applies to both the concrete Embodiment of Fig. 1 to 6 as well as for the schematically simplified Representations of Fig. 8a to 13b. The effective zone for the switching operation of the element 55 is a certain zone 63, namely here the radial inner zone of the control element 40. The ones that function as switching cams Switching edges 61, 62 are in the specific embodiment in Control element 40, as shown in FIG. 5, in a segment-like extension 44 Flange-like part of the control member 40 formed, in one opposite the aforementioned radial zone 63 offset zone, namely in one greater radial distance from axis 30.

7 shows the electrical circuit diagram for the closure according to the invention, of which only the top view of the cylinder core 33 and the lock 19 are shown. As can be seen, the three microswitches are 50 to 50 "in series in an electrical circuit 90, the from a power source 97, e.g. B. a car battery is powered. The two microswitches 50, 50 ', which are indicated by dash-dotted lines Combination switches 53 are combined, act, depending from the actuation of their switching elements 55, 55 ', alternately to one complex switching electronics 91, with which various functions can be controlled in the motor vehicle, such as. B. an anti-theft alarm system. In the present case, the electronic circuitry 91 is also electronic Part of the aforementioned ZV facility integrated, by the can be operated from a variety of ZV actuators 92. In Fig. 7 only one ZV actuator 92 is shown, but others are shown with the Switching electronics 91 connected analog ZV actuators 92 on each door provided the motor vehicle and act z. B. via a retractable and extendable Rod 93 on the respective, provided with these other doors Closures. These further closures are made by the ZV actuator 92 from the ZV facility in an analogous manner to that of the invention Lock controlled. The closure according to the invention, of which, as I said, only the cylinder core 33 is shown in FIG. 7, is located in the tailgate of the motor vehicle.

The handle 10 shown in FIG. 15 is thus also in the tailgate arranged of the motor vehicle. If the handle 10 is actuated, it closes they are the contacts of a switch 94, which is also in the electrical circuit 90 of FIG. 7 is integrated and onto an electric drive 95 of the associated tailgate lock acts. This drive 95 moves depending on the open or closed position of the contacts in the switch 94, a working member 96, which acts mechanically on the lock 19. On in this way the lock 19 is opened electrically.

On this lock 19 can also if the electronic control fails because e.g. B. the power source 97 that operates the circuit 90 failed, be acted on mechanically in an emergency. Serves to as has already been mentioned, the pivotable shown in FIGS. 1 and 6 Working member 18, which is articulated with the one indicated by dash-dotted lines in FIG. 7 Drawbar 17 is connected. This mechanical movement of the The lock is turned by rotating the control member 40 through one provided there Causes lifting cam 98, which is shown in FIGS. 5 and 2. By Rotation of the cylinder core 33 in the direction 76 'to one illustrated there End position 78, the lifting cam 98 abuts against the lower edge of the working member 18, which is illustrated by the pivot arrow 14 in FIG. 2 Work movement. There is still one on the flange part of the control element Stop 99 is provided, which in certain working positions of the control member 40 prevents manipulated pivoting movement 14 of the working member 18, which will be explained in more detail.

The mode of operation of the closure according to the invention should be based on schematic figures 8a to 13b are explained in more detail. There is, as already has been mentioned, the rotatable control member 40 schematically as one shown in the drawing plane longitudinally movable slide.

The above-described pulse-compression spring 46 exercises the already mentioned in Fig. 5 indicated by the arrow 43 axial force on the control member 40 in the sense of engagement of the clutch 35, 45 already mentioned, which between the control member 40 and the cylinder core 33 is located. This Force 43 presses - in the case of the rotary movement taking place here as a longitudinal displacement of the control member in the rotational position 40 'of Fig. 8b - one on the control member 40 provided lifting surface 41 against the control surface 51 from the housing 31. The pulse-compression spring 46 is, as already mentioned, also a torsion spring which the control member 40 with its switching cam 42 in a defined normal position according to FIG. 3. This is normal also drawn out in the diagram of FIG. 8b to be described in more detail below drawn. As already mentioned, this is ensured by the impulse pressure spring 46 provided spring legs 48, 49. Fig. 8a shows a front view the cylinder core 33 in its zero position by one of the position of the key channel 28 certain auxiliary line 70 clarified is. The position of the control element 40 in this zero position 70 is shown in the diagram 8b drawn undrawn and is intended to be "normal position" be designated. In this normal position it is on the control element 40 provided switching cams 42 in a neutral position between the two microswitches 50, 50 '.

8a, two working positions 71 are 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 8a also shows the control element via the engaged coupling 35, 45 40 taken and comes from the drawn in Fig. 8b 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 first microswitch 50, which then switches on the aforementioned anti-theft alarm system and reverses the ZV links 92 via the ZV device 91. Im already 7 is thus in the working position 42 ' the switch 55 closed.

Not only now, but also in advance is the third microswitch 50 "in the continuous closed position because, as already mentioned, the end face 60 of the control member 40 presses its switching element 55 ". By closing switch 50, a voltage pulse is applied across the circuit 90 given to the switching electronics 91. According to what is provided there In this case, the control program is the electrical connection switched off to drive 95 of the associated lock. That means, that closing of the handle 10, already mentioned Switch 94 remains ineffective. The actuation of the handle 10 of Fig. 15 is therefore ineffective; the associated lock 19 cannot be opened become. The associated working position 71 of the cylinder core 33 from FIG. 8a thus proves to be the "secured 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. 8b. Because of the still engaged Coupling 45, 35 is also the cylinder core 33 indirectly, via the control member 40, returned to the normal position shown in extended form in FIG. 8b.

That only changes again when the cylinder core 33 has the key, 8a, 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 clutch 35, 45 is still engaged, the control element becomes from its zero position 70 of FIG. 8b into the one highlighted 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. 8b designated second working position. This is the switching element 55 'of the second microswitch 50' actuated. If in the schematic 7, the switch 50 'closes, a voltage pulse arrives at one second input of the switching electronics 91, because in this case too third microswitch 50 "remains closed. This allows an anti-theft alarm system be turned off again and it becomes the ZV facility reversed. An actuating pulse is applied to the output of the switching electronics 91 given, which first reverses the various ZV actuators 92. Moreover a voltage is permanently applied to the electric drive 95 of the lock created. If the handle 10 is now operated and thus the associated one Switch 94 closed, the drive member 95 is moved by the drive 95 and the associated lock 19 opened in the tailgate of the vehicle. Both the tailgate and all doors can be operated open the respective handle. This working position 72 proves to be thus as the "unlocked position" of the closure mentioned at the beginning. If you let go of the key again after the rotation 75 ', then the key the pulse pressure spring 46 and the control member via the clutch 45, 35 also the cylinder core 33 is returned to its zero position 70.

9a, 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 illustrated analogously to FIG. 9b, the control element 40 is in a limit position 40 ″ already mentioned above axial control means between the closure housing 31 and the control member 40 effective. The lifting surface 41 from the control member has moved up along the housing-side control surface 51. The is illustrated in Fig. 9b by an axial stroke arrow 77. Through this Stroke 77 of the control member 40 "'has the coupling projection 35 of the rotatable but axially fixed cylinder core 33 from the Coupling receptacle 45 of the axially moving control member almost uncoupled. If one rotates the cylinder core via this limit position 73 of FIG. 9a 33 in the sense of the front view of FIG. 12a up to a third working position 74 with the key, so occurs when the limit position is exceeded 73, a decoupling between the coupling projection 35 and the Coupling pocket 45 a. The control link is now free and will, like 10b illustrates automatically by the action of the pulse pressure spring 46 returned to its normal position 40, but remains with it the axial stroke 77 of the control member obtained for the following reason.

As has already been said, the pulse pressure spring 46 also exercises a pressure effect illustrated by the force arrow 43, which also is drawn in the scheme of Fig. 9b and 10b. In Fig. 9b rises So the control element up to the limit position 40 "'against the effect of this Force 43 in the sense of the lifting arrow 77. After uncoupling, this remains Force 43 also in the normal position 40 of the control element of FIG. 10b effective, but now the control member 40 is supported axially at the end from the coupling projection 35 of the axially fixed cylinder core 33. The control member 40 is in Fig. 10b in one of the height of the Coupling projection 35 determined level 67, which is called the "decoupling level" should be designated. This is compared to the previous clutch level 69 offset by the axial distance 68. As can be seen from Fig. 10b, but the cylinder core 33 remains in this further working position 74, where you can remove the key. The tumblers 36 move in a further blocking channel 37 provided there and therefore block this working position 74. This working position is the "safe position" already mentioned several times, the short "safe position" should be designated. There are special ones here in several ways Conditions before.

First of all, the aforementioned ineffectiveness of the associated handle remains 10 received because the first microswitch 50 precedes it, but not the second microswitch 50 'has been actuated. Also the ZV facility has remained in her tax position. Due to the special training of ZV device in the present embodiment is an additional Secured closure. In decoupling level 67 that has Control element 40 released the switching element 55 "of the third microswitch 50". The switch 50 "is therefore in its open position according to the circuit diagram 7. The circuit 90 between the current source 97 and the switching electronics So 91 is interrupted. Actuation of the switch 94 by Actuating the handle 10 is basically ineffective. this is also valid in mechanical terms.

As can be seen in FIG. 10b, the stop already mentioned above has become 99 on the control element 40 in the decoupling plane 67 so far axially displaced, that it protrudes into the working path of the mechanical working member 18. Manipulations on working member 18 by intrusion tools are therefore basically ineffective. In contrast to that is in the recognizable in Fig. 8b Axial position of the control member 40 in the clutch plane 69 of the stop 99 removed from the work path of the working member 18. In this case actuation of the lock by turning the key 76 'up to in Fig. 3 shown lock actuation position 78 possible. Then the lock can can also be opened with the key.

The switching cam 42 "'in is already in the limit position 40"' of FIG. 9b an axial distance 68 to the switching element 55 of the microswitch 50 come, which is why in the later reset caused by the spring 46 of the control member in the normal position 40 "Safe" of Fig. 10b Movement of the switching cam in the uncoupling plane 67 takes place. In order to the switch cam attains its normal position shown in FIG. 9b 42 at an axial distance 68, which is determined by the height difference between the two levels 67, 69 is determined. The cam 42 moves back to its normal position "safe" at microswitch 50, but without Actuation of the switching element 55 from the microswitch 50. The preceding when switching to the secure position 71, the The anti-theft alarm system is therefore retained and the microswitch 50 becomes not operated again.

8c, 9c and 10c show alternative configurations to that described above Stroke control of the control member 40 between its two levels 69, 68, analogous to FIGS. 8b, 9b and 10b. In all other respects, the same are the same Ratios as in FIGS. 8b, 9b and 10b. It is enough, just address the differences; in all other respects the previous one applies Description.

In this alternative, the coupling parts 35, 45 have a special profile, namely, the one flank 25 of the coupling projection 35 is inclined trained, as well as the clutch receptacle 45 a correspondingly inclined Has inner surface 24. Furthermore, the closure housing 31 is a stationary one Stop 23 provided. These profile shapes also result from the 1 to 6. The inclined inner surface can be seen 24 of the receptacle 45 in Fig. 1, the inclined flank 25 on the coupling projection 35 in FIG. 5 and the stop 23 on the housing part 20 of FIG. 6.

When key-related rotation of the cylinder core 33 is engaged standing clutch 35, 45 moves the control member 40, as by the movement arrow 57 is illustrated in FIG. 8c. The control element bumps 40 with its edge 58 to the housing-side stop 23, which is why then the further movement 57 of the control member 40 is ended. When turning on of the cylinder core 33, the control member 40 slides with its inner surface 24 up on the inclined flank 35 of the coupling member. It comes in the limit position 40 '' 'of the control element shown in FIG. 9c to that already 9b described in connection with FIG. 9b, which exist remains when you move the cylinder core 33 up to the safe position described 74 continues to rotate. Then, as FIG. 10c shows, the control element is located 40 in the uncoupling plane 67. By the impact of the control element edge 58 at the housing stop 23, the angle of rotation is precisely defined, from which the stroke movement 77 of the control member from the clutch plane 69 begins in the decoupling level 67.

11a and 11b are the same relationships as in Fig. 10a and 10b before. The only difference is that in Fig. 11b also the mode of operation of the components already explained in connection with FIG. 5 38, 39 is explained. 11b to 14b show a so-called overload protection on the lock 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. The channel sleeve 38 is axially fixed but rotatable in the closure housing 31. The Sliding ring 39 and the channel sleeve 38 have on their facing each other End faces a mutually complementary lifting profile 81, 82. This consists, as can also be seen from FIG. 5, of an approximately trapezoidal shape Recess 82 in the channel sleeve 38 and a complementary elevation 81 in the sliding ring 39. Two are expediently diametrical to one another Lifting profiles 81, 82 of this type are provided. As a further part of this A compression spring could be provided for overload protection, but will in the present case the one already generated by the pulse pressure spring 46 Axial force 43 used, which is also shown in FIGS. 11b and 12b is. The spring 46 thus fulfills a third function.

As long as the proper key is not in the key channel 28 of FIG. 11a is inserted, as shown in FIG. 11b, 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. However, if the cylinder core 33 is not replaced by the proper key, but turned by a burglary tool in the direction of arrow 86, the channel sleeve 38 also becomes over the engaging tumblers 36 rotated and therefore, when a certain limit load is exceeded Lifting profile 81, 82 lifted against the spring force 43. This situation is shown in Fig. 12b. Now the sliding ring 39 supports the control member 40 with its end face 89 opposite the lifting profile 81.

The lifting profile 81, 82 can execute a longer stroke 65, than the aforementioned lifting movement 77 between the coupling plane 68 and corresponds to the decoupling level 67. By the one shown in Fig. 12b Axial stroke 65, the control member 40 reaches a third axial plane, which should be referred to as the "overload protection level". The safe position of the control member 40 thus remains ensured even in the event of a break-in. As FIG. 12a shows, the cylinder core 33 can be removed from the burglary tool be rotated according to the rotation arrow 86 without the ineffectiveness the handling operation is eliminated; the associated lock remains still closed.

13b to 14b 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. 14a 33 result from a violent rotation 86 by means of an intrusion tool the conditions shown in Fig. 14b in cross section at the point marked XIVb-XIVb in FIG. 13b. Is as has already been said in connection with FIG. 12b, the cylinder core 33 via the engaging tumblers in a rotationally fixed manner with the channel sleeve 38 connected, so these parts, like the rotation arrow 86 of Fig. 14b clarified, shot together. The roller 85 leaves the housing side Recess 87 and moves fully into the core-side recess 88.

14a shows the situation at the same point as FIG. 14b, if the relationships explained in connection with FIGS. 8b to 10b exist where the cylinder core 33 has a proper key is twisted. In this case, those in connection with Fig. 11b tumblers 36 on the circumference of the cylinder core which have already been described several times 33 sorted. The channel sleeve 38 is not rotatable because it is secured by the roller 85. The role now moves into the housing side Recess 87 from, but still engages sufficiently the opening 84 to the channel sleeve 38 rotatably in the closure housing 31 to secure. The roller 85 gives the other recess 88 in FIG. 14 a free and therefore leaves the above-described rotation 76 of the cylinder core 33 compared to its channel sleeve 38.

15, the handle 10 consists of a spring-loaded Handle flap 13, which is in a recessed grip 12 of a handle housing 11 is let in. This handle housing 11 is in a tailgate 100 integrated, in which the closure housing 31 is also located. The Handle flap 13 is in the handle housing 11 via a pivot axis 15 pivoted and can, if with one hand 59 a pressure in Arrow 64 is exercised, arrow 16 in the dash-dotted line Position 13 'are pivoted.

The handle flap 13 is, as shown in FIGS. 16 and 17, with a side Provide pin 80 which protrudes from the housing 11. On the outside of the housing 11, the switch 94 is attached, with its switching element 83 the pin 80 cooperates. It comes to the context with the circuit diagram of Fig. 7 explained switching movements and leads to the consequences already mentioned. The handle flap 13 together with the Inner surface of the housing 11 is covered by a rubber skin 101, which a watertight integration of the entire handle 10 in the trough 12 of the tailgate 100 guaranteed.

The grip flap 13 is pulled out by a latching device 102, 103 Starting position of Fig. 15 held. This locking device 102, 103 but also fulfills another, new function, based on what 18 becomes clear. The latching device initially comprises an elastic one Locking element 102, which here consists of a spring-loaded ball 104. This ball 104 is under the action of a compression spring 105, which is integrated with the ball 104 in a cup-shaped housing 106. The entire structural unit 104, 105, 106 is, as is particularly clear from FIG. 17 emerges, embedded in the side edge 107 of the handle flap 13, whereby the spring-loaded ball 104 against the side wall of the handle housing 11 is directed. There is a side step 108. Also in 18 is a dash-dot line of the already mentioned release position 13 'of the handle flap clarified and the arrow of the pivoting movement 14 indicated. The side step 108 serves as a counter-locking element 103 to the aforementioned elastic locking element 102.

It is remarkable that this counter-locking element 103 has an inclined surface, which extends at an angle to the pivoting movement 14. This tendency is shown in dash-dotted lines in FIG. 18, designated 112 and shall hereinafter be referred to as the "slope surface". This tendency ensures that the elastic member 102 in the starting position 13 of the Handle flap is more relieved than in the actuating position 13 '. Because the locking element 102 strives to the maximum relaxed position to get there, it will extend as far as possible along the inclined surface 112 search. This maximum relief is achieved when the spring-loaded Ball 104 on step edge 109 fully out of detent housing 106 is extended. The elastic latching element 102 thus ensures that the handle flap is held in its starting position 13 in FIG. 18. This creates the locking effect.

If the handle flap is moved into its actuating position 13 ', it presses the ball enters its dot-dash position 104 'of FIG. 18. The compression spring is in the compressed position 105 'of FIG. 18 brought. This creates an effect in the direction of arrow 110 of FIG. 18 Force on the pivoted handle flap 13 '. This creates on the slope surface 112 of the handle housing 11 a in the backward pivot sense force component 111 of the handle flap, which has a restoring torque exerts on the pivoted handle flap 13 '. This restoring moment strives to move the handle flap into its starting position 13 of FIG. 18 to transfer. The locking device 102 designed according to the invention, 103 is thus also a reset means for the handle flap 13.

This double function of the locking device 103, 104 allows space-saving Construction and saves the otherwise necessary components. In addition, the combination of reset means and locking element a crackling sound when actuating the handle flap between the Positions 13, 13 'arise. This sound announces the user successful reversal of switch 94 audible. This double function is independent of the closure of Fig. 1 to 14b, of its own inventive Importance.
