Description

The invention relates to a lock system for a closure element of a property, comprising a lock having an electric drive device, a manually operated control element and a closure element, which has a locking element which locks or unlocks cooperating with a lock element of the lock, wherein in a normal unlocking operation by manual Triggering an electrical unlocking operation of the lock system takes place.

A lock system of the type mentioned is for example from the DE 10 2014 112 122 A1 known. In addition, lock systems are known which have a lock, which has an electric drive device. The lock is associated, for example, a door, wherein it is installed in a frame of the door. The door has a door leaf, in which a closing element of the lock system is installed. The closure member has a locking member which cooperates with a lock member of the lock to lock or unlock the door. The known lock system has the problem that in case of failure of a component and / or power failure, an existing lock can not be canceled, which is very problematic, especially in an emergency situation.
The invention has for its object to improve the security of a lock system of the type mentioned, in particular to be able to unlock in an emergency situation.

This object is achieved in that in a Notentriegelungsbetrieb a mechanical unlocking of the lock system is carried out characterized in that by the manual operation of the control element thereby mechanically driven extraction of the locking element takes place from the lock element. In normal operation, a normal electrical release is made. This operation is defined as normal unlock operation. It is caused by a manual release, that is, the user of the lock system manually releases the Unlocking, for example, by entering a pin code in a keypad used a transponder, operated a handle or a lock cylinder actuated by means of a key and so on. This always turns on the electric drive device, which unlocks the lock system. If there is a lock and in particular an emergency occurs, which requires unlocking the lock system, the lock system according to the invention enables the emergency unlocking operation, which is not carried out electrically, but purely mechanically. If, for example, the power fails, so that the electric drive device can not be operated, then the mechanical unlocking operation ensures unlocking. Should a mechanical component of the drive device fail, then an unlocking, regardless of whether electrical current is present or not, also perform, namely the emergency unlocking operation according to the invention enables the unlocking in that a withdrawal of the locking element takes place from the lock element. The mechanical unlocking is thus not effected by the lock, but by the closing element. In the closure member, the locking member is mechanically displaced such that it is disengaged from the lock member, whereby the lock is released, and therefore the closure member can be opened. It is important that in the emergency unlocking operation by the manual operation of the operating element, the applied manual driving force is forwarded to cause the extraction of the locking element from the lock element. The closure element of the property is preferably a window, a door or the like. In particular, it may be provided that in the case of a door the lock is located in the door frame / window frame and that the closing element is installed in the door leaf. Alternatively, a reverse solution is possible, so an installation of the lock in the door and an installation of the closing element in the door frame / frame.

According to a development of the invention, it is provided that the operating element is manually displaceable in a plurality of positions, that in the manual displacement of the operating element in a first position of the normal unlocking operation takes place and that in the manual displacement of the operating element in a second position of the emergency unlocking takes place. Accordingly, both the normal unlocking operation and the emergency unlocking operation can be performed by means of only one operating element. For this purpose, the operating element is displaced to a first position by the user, which leads to the normal unlocking operation. Relocates the user of this control element in the second position, the emergency unlocking operation is performed.

A development of the invention provides that the operating element has a basic position from which it can only be displaced into the first position and that the operating element can be displaced from the first position into the basic position or into the second position. It follows that from the basic position, the second position is only reached when in the course of the relocation, the first position (possibly short term) is taken. For daily normal use, this means that the user always moves the control element from the basic position only in the first position for the normal unlocking. He will therefore move the control only a correspondingly short displacement path and then stop the shift, so the second position that leads to Notentriegelungsbetrieb, not cause. However, should the emergency unlocking operation be necessary, it will use the same control but operate a longer displacement path so that it will move from the home position to the first position and from there to the second position, with the result that it will pull out due to manual operation of the locking element takes place from the lock element and the lock system is unlocked.

A further development of the invention provides that the actuating travel of the operating element from the basic position to the first position is shorter, in particular approximately half as long, than the actuating travel from the first position to the second position. The user can thus bring about the electric unlocking operation in the normal unlatching case by a correspondingly short displacement, which is very convenient. If the exceptional case of an emergency release, so the operating element along a correspondingly large actuation path to relocate, further wherein the force for the mechanical extraction of the locking element must be applied from the lock element.

It is preferably provided that the manual release takes place by manually activating an electrically operating control element or by manually displacing the operating element into the first position. This has already been discussed above. The purely exemplary input of a pin code into a keypad, the use of a transponder and so on are examples of the manual activation of the electrically operating drive element. Alternatively, if a manual displacement of the operating element in the first position, so this does not require an electrically working assembly.

It is preferably provided that the operating element is a handle, in particular a door handle. This is displaced in the normal unlatching operation only along a short path (about one third of the total distance depressed). In case of an emergency unlock operation, the handle becomes fully depressed, it first enters the first position (one third of the total path) and from there to the second position (two-thirds of the total path).

Additionally or alternatively, a key-operated lock cylinder can be provided as the control element. By means of a key, the lock cylinder is manually operated to cause either the normal unlock operation or the emergency unlock operation. In the normal unlock mode, the key movement results in e.g. for switching an electrical switch that turns on the electric drive device. In the emergency unlock operation, the torque exerted on the key by the user is used to pull the locking member out of the lock member.

A preferred embodiment of the invention provides that the lock element is a pivoting latch and that the locking element is a locking pin, also called locking pin.

According to a development of the invention it is provided that the pivotal latch has a pivot axis which runs parallel to a longitudinal axis of the locking pin. The longitudinal axis indicates the axial longitudinal extension of the locking pin.

It is preferably provided that in the electrical unlocking operation the locking pin emerges radially from the pivoting latch by pivoting the pivoting latch. Accordingly, the pivotal latch is pivoted about its pivot axis by means of the electric drive device such that the locking pin can exit. This causes an unlocking.

In the mechanical unlocking operation is preferably provided that the locking pin axially exits the pivotal latch. While in the electric unlocking operation, a radial movement of the locking pin - caused by an opening of the closure element - is present, takes place in the mechanical unlocking, ie in the emergency unlocking, an axial locking pin displacement caused by the manual operation of the control. In particular, it is provided that this does not move during the axial extraction of the locking pin from the pivotal latch.

According to a preferred development of the invention, it is provided that, before pulling out the locking element, the lock element is displaced electrically in such a way that that the closing pressure of the locked lock system decreases, this electrical displacement is fed from an electric power storage. By the locking process loads on the locking element, a lateral closing pressure, which makes it difficult to pull out of the locking element of the lock element. In particular, when the lock system is used in a closing element of a property, in particular a door, a window or the like, the pressure exerted by compressed seals of these components increases the closing pressure. For the manual extraction of the locking element from the lock element, therefore, the closing pressure is reduced before pulling out, that the lock element is electrically displaced. This shift takes place in particular by pivoting the lock element designed as a pivoting latch. However, the pivoting does not take place until complete unlocking, but only by a relatively small pivot angle, which is sufficient, however, to reduce the closing pressure, so that the locking element can be pulled out of the lock element with little effort. The displacement of the lock element to reduce the closing pressure is carried out electrically by means of the electric drive device, but in the case of power failure for this purpose, no electrical energy is available. For this purpose, the electric power storage, for example, a capacitor bank, is provided which provides sufficient electrical energy for the electrical displacement of the lock element to reduce the closing pressure.

The invention further relates to a closure element of a property designed as a door, having a lock system, as has been described above in the various design variants.

Furthermore, the invention relates to a method for performing a normal unlocking and an emergency release in a lock system, as has been described above in various embodiments.

In the method, in particular, a lock system for the closure element of the property is provided, which is the electric drive device having lock, the manually operated control element and the closing element is provided, wherein the closing element has the locking element, which cooperates with the lock element of the lock or unlocking wherein in the normal unlocking operation by the manual release, an electrical unlocking operation of the lock system is performed and in the emergency unlocking operation, the mechanical unlocking operation of the lock system thereby is carried out that takes place by the manual operation of the operating element, a pulling out of the locking element of the lock element.

The FIG. 1 shows a trained as a door 1 closure element 2 of a property. The door 1 is, for example, a front door. The door 1 has a wing element 3, which is mounted in a frame 4 rotatably about a vertical axis 5. The door 1 is in the Figures 1 and 2 partially open, with the FIG. 1 an inside view and the FIG. 2 a Exterior view. The inside view is a view of the door 1 from the inside of the property and the outside view is a view of the door from outside the property.

According to FIG. 2 the frame 4 is equipped with several locks 6. The FIG. 1 shows that each of the locks 6 can cooperate with a closing element 7, wherein the closing elements 7 are located on the wing element 3. Each closing element 7 has a locking element 8, which is preferably designed as a locking pin 9. The locks 6 and the closing elements 7 are located in a rebate air zone 10 of the closure element 2, preferably on those vertical beams 11 and 12 of the wing element 3 and the frame 4, which lie opposite the vertical axis 5. In the embodiment of Figures 1 and 2 a total of four locks 6 and four closing elements 7 are provided in said area, of course, more or fewer locks 6 and closing elements 7 may be provided and also more spars of wing element 3 and frame 4 may be provided with locks 6 and closing elements 7, For example, horizontally extending elements and / or in the threshold of the door. It is also possible to additionally provide the band side of the door, that is to say the side which has the vertical axis 5, with at least one lock 6 and at least one closing element 7. For the sake of simplicity, only one lock 6 and one closing element 7 will be described below - unless there are special designs. If more locks 6 and closing elements 7 are provided, they are designed accordingly. Since a plurality of spaced-apart locks 6 and closing elements 7 can be used, in particular over at least part of the circumference of the closure element 2, the closure element 2 can be locked absolutely securely, with even corresponding contact pressure even unequal closing wing elements 3, for example because they warped are locked and used with at least partial elimination of the delay. Possible leaks are eliminated.

The FIG. 3 It has a lock housing 13, which has a bottom wall 14, a ceiling wall 15 and two longitudinal walls 16 and 17 and two end walls 18 and 19. The ceiling wall 15 is in the FIG. 3 shown transparent to throw a look into the interior of the lock housing 13 can. On the bottom wall 14 a plurality of studs 20 to 25 are attached and / or formed integrally with the bottom wall 14. On the stud bolts 20 to 25 are - as in FIG. 3 seen - components of the castle 6 rotatably or pivotally mounted. There are gears 26, 27, 28, 29, 30, 31 and 32nd provided, which together with a screw 33 form a transmission 34. The gears 26 and 27 are as a double gear, the gears 28 and 29 are as a double gear and the gears 30 and 31 are also formed as a double gear, that is, there are two gears axially fixed to each other, in particular integrally connected. The worm 33 is arranged non-rotatably on a drive shaft 35 of an electric motor 36 located in the interior of the lock housing 13. The worm 33 meshes with the gear 26. The gear 27 meshes with the gear 28. The gear 29 meshes with the gear 30, the gear 31 meshes with the gear 32. In the manner described above, a strong reduction, starting from The drive shaft 35 of the electric motor 36 to the gear 32. As well as the gears 28 and 29 can be seen, the gears 26 and 27 and 30 and 31 have large diameter differences in order to provide the largest possible reduction. The gears 27 and 31 are in the FIG. 3 however, not apparent since they are covered by the gears 26 and 30. The electric motor 36 together with the gear 34, a drive means 37, with which a locking member 38 is driven. The locking member 38 is formed as a rotary locking member 39. It is rotatably mounted about a locking member axis 40, wherein the locking member axis 40 is formed by the stud 24. The rotary locking member 39 is located in the interior of the lock housing 13. Further, a pivot latch 41 is pivotally mounted in said lock housing 13. The storage takes place by means of the stud bolt 25. The pivot latch 41 is shown transparent to recognize details of the construction can.

The rotary locking member 39 has a plurality of locking elements 42 which are offset in relation to each other over their circumference. In the embodiment of FIG. 3 three locking elements 42 are provided which are each offset by 120 ° to each other. Further, the rotary locking member 39 has a gear 43 which has a top 44 and a bottom 45. The underside 45 faces the bottom wall 14. On the top 44, the locking elements 42 are fixed, in particular integrally formed with the gear 43. The locking elements 42 are formed as extending in the direction of the locking member axis 40 projections 46, wherein the projections 46 in particular as round bolt-like projections 46 with flats 46 'are formed. As a result of the peripherally flattened round bolts 46 ", an asymmetry in the interaction with the pivot latch 41 results such that the time for unlocking the lock 6 is shorter, in particular significantly shorter, is considered the time for the lock. It can preferably be provided that the blocking elements 42 by means of radial extending spoke webs 47 connected to each other, in particular integrally connected, are. The spoke webs 47 are centrally connected to a hub 48, in particular integrally connected, wherein the locking member axis 40 extends centrally through the hub 48. In particular, it is provided that the gear 43, the locking elements 42, the spoke webs 47 and the hub 48 are integrally formed with each other.

According to FIG. 3 It can be seen that between each two adjacent blocking elements 42 over a peripheral region of the rotary locking member 39 extending clearance 49 is located. Furthermore, from the FIG. 3 can be seen that the gear 32 meshes with the gear 43, that is, that the electric motor 36 in operation via the gear 34, the rotary locking member 39 drives. The arrangement is designed such that a drive of the rotary locking member 39 takes place in only one direction of rotation, which is represented by an arrow 50. In the embodiment of FIG. 3 the rotation of the rotary locking member 39 is in the clockwise direction (when viewed from above on the top wall 15 of the lock housing 13). The electric motor 36 is therefore operated in only one direction of rotation to drive the rotary locking member 39 in only one direction of rotation.

The pivot latch 41 is disposed in the interior of the lock housing 13 and pivotally mounted about the stud bolt 25. According to the FIGS. 3 to 5 has the pivot latch 41 has a cam 51 which - as will be explained in more detail below - with the rotary locking member 39, in particular with the locking elements 42 of the rotary locking member 39, operating state dependent cooperates. The cam 51 is spaced from a bearing hole 52, in which the stud bolt 25 engages. Basically, the pivot latch 41 has a top 53, a bottom 54 and a circumferential end 55 on. The cam 51 has in the region of the end face 55 a control cam 56. As in particular the FIG. 5 shows, the cam 51 extends only over a portion of the thickness of the pivot latch 41, wherein the portion of the thickness remaining in the region of the cam 51 is formed as an open area 57 for partially receiving the gear 43 of the rotary locking member 39.

In the region of the front side 55, the pivot latch 41 has a receiving recess 58 for the locking element 8, in particular for the locking pin 9, on. Accordingly, the receiving recess 58 to the end face 55 of the pivot latch 41 is open and runs - in particular the FIG. 3 It can be seen - at least partially at an acute angle to the radial direction, wherein the radial direction is a radial, which passes through a pivot bearing 59, wherein the pivot bearing 59 is formed by the stud bolt 25 and the bearing hole 52. The radial direction is in the FIG. 3 by dashed line 60 indicated. In particular, it is provided that the receiving recess 58 has no fixed acute angle to the radial direction, but arcuate, in particular slightly arcuate, runs, as shown in FIG. 3 clearly shows.

The pivot latch 41 is resiliently urged in a preferred direction. The preferred direction is in FIG. 3 indicated by an arrow 61. As a result, the pivot latch 41 is acted upon in its Entriegelstellung. In this unlocking position, the input 55 located on the end face of the receiving recess 58 is aligned with an inlet slot 62 of the lock housing 13. The inlet slot 62 passes through the longitudinal wall 16 and the bottom wall 14 in each case a little way. Preferably, the inlet slot 62 extends parallel to the end wall 18. In particular, it is provided that the inlet slot 62 is funnel-shaped on the input side by corresponding oblique course 63, whereby a drogue for the locking element 8 is formed, which ensures automatic height compensation.

The height of the receiving recess 58 extends only over a region of the thickness of the pivot latch 41, so that the upper side 53 of the pivot latch 41 is designed to be closed and thereby has a high mechanical strength. For biasing the pivot latch 41 in its preferred direction is a spring 64 ( Figures 3 and 5 ), which turns around the stud bolt 25 and has two end arms 65, wherein the one end arm 65 is supported on the pivot latch 41 and the other end arm 65 on the lock housing 13 under prestress. To limit the pivot angle of the pivot latch 41, this has a stop surface 66 which can cooperate with a mating surface 67 of the lock housing 13 (see FIG. 4 ).

In order to ensure a simple assembly of the spring 64, it is preferably provided that the spring 64 on the not yet inserted into the lock housing 13 pivot latch 41 can be fixed, in particular clamped, is. If the pivot latch 41 is subsequently inserted into the lock housing 13, this is done in such a way that the corresponding end arm 65 of the spring 64 is introduced into a recess of the lock housing 13, the pivot latch 41 is rotated to generate a bias of the spring 64 and simultaneously pressed into the end position becomes.

In the interior of the lock housing 13 - a control device 69 is housed - mostly in a demarcated compartment 68 - which has a printed circuit board 70 with control electronics and electrical connections 71, the latter are accessible by means of an incision 72 of the lock housing 13 from the outside. The electrical connections 71 form a electrical interface 122. The circuit board 70 is electrically connected to the electric motor 36 and has two sensors 73 and 74 on. The two sensors 73 and 74 belong to the control device 69 and interact contactlessly with sensor control elements 75 and 76 of the rotary locking member 39 and the pivot latch 41 together. Preferably, the sensors 73 and 74 are designed as Hall sensors 77. The sensor drive elements 75 and 76 are designed as permanent magnets 78. The arrangement is such that each blocking element 42 is associated with a Sensoransteuerelement 75. For this purpose, each blocking element 42 has a recess 79, which is formed in particular as a blind hole. In the respective recess 79 is the associated Sensoransteuerelement 75. The Sensoransteuerelement 76 is associated with the pivot latch 41. The pivot latch 41 has a recess 80 in which the sensor drive element 76 is located. The FIG. 3 indicates that the sensor 73 can cooperate with the Sensoransteuerelementen 75, in such a way that with the sensor 73 always preferably that of the three Sensoransteuerelemente 75 temporarily cooperates, depending on the rotational position of the Drehsperrglieds 39 the sensor 73 closest , The sensor 74 is opposite to the sensor drive element 76, wherein the distance between these components changes depending on the pivot position of the pivot latch 41. From all of this, it will be understood that the sensor 73 is capable of sensing the rotational angular position of the rotary locking member 39 and thus the positions of the locking members 42 and that the sensor 74 is capable of detecting the pivotal position of the pivoting latch 41. The respective information of the sensors 73 and 74 is thus available to the control device 69.

The operation of the lock 6 will be explained below for a locking and unlocking operation. It is assumed that the shutter member 2 is in a position as shown in FIGS Figures 1 and 2 shows, that is, the wing member 3 is in an open state. If, for example, the door 1 is closed by a person who wants to leave the property, the person has an external knob 90 (FIG. Figures 1 and 2 ) and the wing element 3 pivots on the frame 4 about the vertical axis 5, the situation results in accordance FIG. 6 with respect to the lock 6. Below, only one of the locks 6 will be discussed, with corresponding situations occurring in the other locks 6 of the door 1. The FIGS. 6 to 9 each show on the left side schematically the position of the preferably designed as a locking pin 9 locking element 8 in the inlet slot 62 of the castle 6. On the right side of the show FIGS. 6 to 9 the respective left-side associated position of the rotary locking member 39 and the pivot latch 41st

According to FIG. 6 occurs when closing the door 1, the locking element 8 at least partially into the inlet slot 62 and the receiving recess 58 and thereby acts on a side wall of the receiving recess 58, with the result that upon further entry in accordance with FIG. 7 the pivot latch 41 is pivoted a little way. The mentioned closing of the closure element is detected by the displacement of the pivot latch 41 by the control device 69 in that the sensor 74 of the circuit board 70 detects the new position of the adjacent sensor control element 76 of the pivot latch 41. As a result, the control device 69 starts the electric motor 36, which via the gear 34, the rotary locking member 39 in the only one direction of rotation (in the exemplary embodiment in the clockwise direction) drives. The relevant locking element 42 occurs against the control cam 56 and thereby rotates the pivot latch 41. As a result, the locking element 9 is further retracted in this and in the inlet slot 62 due to the corresponding, in particular curved course of the receiving recess 58. In the further course of the locking operation, the rotary locking member 39 is in the position according to FIG. 8 rotated, this position corresponds to the locking position. In this position, the electric motor 36 turns off. Switching off takes place by means of the already mentioned control device 69 by sensing the position of the rotary locking member 39, since this position is detected by interaction of the sensor 73 on the printed circuit board 70 and the adjacent sensor element 75. The formation of the control cam 56 is made such that an optimal force-displacement ratio is present, which is therefore initially a lot of way with little force and later little way with a lot of force to almost infinite force. In FIG. 8 In the locking operation, the anti-rotation member 39 preferably has a uniform speed, and the rotational speed of the pivotal latch 41 is decreased due to the present eccentricity. This benefits the closing force curve, which is initially low and then rises sharply to the end position, that is, the contact pressure generated increases sharply. This has the consequence that the wing member 3 is strongly pressed against an existing seal on the frame 4. In the position according to FIG. 8 the contact pressure forces occurring are derived by the present dead center position in the pivot bearing 59 torque-free. If an unlocking operation is now to be carried out, then the operator, for example by key operation (also code entry on an input field), takes fingerprint actuation or correspondingly the drive device 37 back into operation. By the exemplified key operation, Fingerabdrucksensorbetätigung or according to the control device 69 is supplied to an electrical control signal 120, in particular via the electrical connections 71st fed. At the same time the control device 69 is due to the state of the sensor 73 and / or the sensor 74, the operating position of the lock 6 known, that is, it can in particular by correlating the applied signals, the electric motor 36 back into operation. This rotates in his previous direction of rotation, ie in the same direction as before, so that it comes to the disengagement of the locking element 42 of the pivoting latch 41. This is done by very short paths and therefore almost in real time (less than 0.5 s), that is, there are no waiting times. It is the unlocking according to FIG. 9 in front. Since the control device 69 senses the process by the previously mentioned sensors 73 and / or 74, the rotary locking member 9 is rotated further, in a position which is again the FIG. 6 equivalent. This position is detected by the sensors 73 and / or 74, whereby the electric motor 36 is turned off. By releasing the pivot latch 41 pivots back, supported by the spring 64, whereby a release of the locking element 8 takes place and the door 1 can be opened.

According to the Figures 1 and 2 In such a case, no transition of an electric cable from the frame 4 to the movable wing member 3 is required, since the electrically powered locks 6 are in the frame 4. Alternatively, it is also possible for the locks 6 to be located in the wing element 3 and the closure elements 7 in the frame 4. The mentioned cable transition to the wing element 3 is required in the arrangement of the locks 6 in the wing element 3 in order to supply the electric motors 36 of the locks 6 and to supply the control signal 120.

The FIG. 10 shows a closing element 7 and a control element 130. Preferably, the control element 130 further locking elements 7 are assigned to lock the closure element 2 of the property can safely. For the sake of simplicity, the FIG. 10 However, only the mentioned a closing element 7. The closing element 7 and the control element 130 is assigned a faceplate 131, on the back of a drive rod 132 extends. In the embodiment of Figures 1 and 2 are locks 6 on the frame 4 of the closure element 2 and closing elements 7 and the control element 130 on the wing element 3 of the closure element 2. Of course, a reverse arrangement is conceivable, as already explained. The operating element 130 is according to FIG. 10 designed as a pure control element 130, that is, it has no trap and no latch. Alternatively, it is also conceivable that - as in a normal door lock - additionally a case and a bolt can be provided.

According to FIG. 11 For example, the operating element 130 has a housing 133 in which a nut 134 is rotatably mounted. The nut 134 has a square opening 135, which can be formed with a square bar of a handle 136, which can be designed in particular as a door handle 137 ( FIG. 1 ), can be coupled. The nut 134 is coupled to a pivoting lever 138, whose free end 139 engages under a driving block 140 which is fastened to a carriage 141 mounted in the housing 133. By means of a spring 142, the nut 134 assumes a basic position, as shown in the FIG. 11 evident. The carriage 141 is connected to the drive rod 132 (this is - like the FIG. 11 shows - designed in several parts). The housing 133 has a receptacle 143 for a key-operated lock cylinder, not shown, which can cooperate with a sliding lever 144 to pivot a pivot member 159, which can also cooperate with the driving block 140. Consequently, the pivot lever 138 can be displaced on the one hand via the handle 136 and on the other hand via the lock cylinder (if present). In the housing 133, an electrical switch 145 is arranged, the release button 146 can interact with the driving block 140. The FIG. 14 illustrates the closing element 7. This has a closing element housing 147 in which a push bar 148 is mounted longitudinally displaceable, the ends of which are in communication with the multipart drive rod 132. Further, a pivot lever 149 is mounted in the closing element housing 147, which is designed as a double lever and with an end portion 150 adjacent to a pin 151 which is fixed to the handlebar 148. The other end portion 152 of the pivot lever 149 is adjacent to a driver 153 which is connected to the locking element 8 formed as a locking pin 8 of the closing element 7. The locking pin 9 is mounted longitudinally displaceable in a guide 154 and passes through the faceplate 131 in the region of an opening 155.

The result is the following function. It is assumed that a closure element 2, which is locked by means of the locks 6 and the closing elements 7. First, the normal unlock operation will be explained. This is done by manual triggering, in the exemplary embodiment such that an operator depresses the not shown, but explained handle of the operating element 130 to a first position. This first position is in the FIG. 12 indicated. Here, the nut 134 is slightly twisted, such that the pivot lever 138 moves the driving block 140 into the region of the release button 146, whereby the button 145 is electrically triggered. The button 145 is electrically, Electromagnetically, optically and / or mechanically with the drive means 37 and the lock 6 in combination (not shown), whereby an electrical release, so an electrical Entriegelungsbetrieb the respective lock 6 is performed, whereby the respective locking pin 9 is released and the door 1 is opened can be. Since the driving block 140 entrains the carriage 144 and thus the drive rod 132 during its displacement, this will displace to some extent, but not with the result that in the associated closing elements 7, a retraction of the locking pin 9 takes place. Overall, the manual displacement of the operating element 130 leads from the basic position to the first position, that is, to an electrical normal unlocking operation.

If, for example, in the event of a power failure, so that the electric drive device 37 of the respective lock 6 can no longer work-an emergency unlocking operation is carried out, a purely mechanical emergency unlocking operation becomes possible. This is done by manual operation of the control element 130 from the basic position to a second position, wherein by the manual operation of the control element 130 is a purely mechanically driven pulling out of the corresponding locking pin 9 of a lock element 156 of each lock 6, wherein the lock element 156 of the corresponding Swing latch 41 is formed. The FIG. 13 shows the displacement of the control element 30, so the handle 136, not shown, to the second position. Although the button 145 is actuated in this case, but this does not lead to an electrical unlocking, since the power has failed. Rather, by pivoting the nut 134 in the second position by means of the pivot lever 138 via the driving block 140 of the slide 141 so far shifted that - via the drive rod 132 of the handlebar 148 in the position according to FIG. 15 reaches, in which the bolt 151 has the pivot lever 149 pivoted so far that the end portion 152 completely retracts the locking pin 9 via the driver 153. The FIG. 15 shows that it is retracted to the level of the faceplate 131. As a result, it has been pulled out by the manual operation of the pivot latch 41 of the associated lock 6, so that a mechanical emergency unlocking operation is present. However, since - as already explained above - transverse forces by closing pressure (sealing pressure and so on) acts on the respective locking pin 9, - according to a preferred embodiment of the invention - before a purely mechanical unlocking - as described above - the following is executed. If there is a power failure, this is registered by the drive device 37, in particular the control device 69, the following process triggers. In the drive device 37, in particular the control device 69, there is an electrical power storage, for example, a capacitor bank. If the power failure sensed, the capacitor bank enters into function, that is, it is connected to the electric motor 36 so that this - contrary to the rotational direction present in normal operation - the rotary locking member 39 so far rotated so that the pivot latch 41 is no longer in the locked position according to FIG. 16 is held, but can swing back a little way so that the retracted by her locking pin 9 due to the oblique retraction path can move back a bit, as in FIG. 17 is shown. This has the consequence that the locking pressure acting on the lock system (eg caused by the seals and so on) is reduced such that the mechanical removal of the locking element 8, ie the locking pin 9, subsequently taking place in the emergency unlocking mode, thus out of the lock element 156 the pivot latch 41, is facilitated.

Preferably, the arrangement is such that the operator in Normalentriegelungsbetrieb the operating element 130, so the handle 136, to trigger the electrical release only slightly depress to reach the first position, in particular only one third of the total actuation path. If the operator wants to carry out the emergency unlocking operation, he moves the operating element 130, ie the handle 136, over the entire actuation path, ie from the basic position beyond the first position to the second position, wherein the actuation path between the first position and the second position preferably twice as long as from the basic position to the first position.

Was a purely mechanical Notentriegelungsbetrieb performed in the embodiment with electric power storage, the pivot latch 41 of each lock 6 is brought by the corresponding locking pin 9 in a Vorverriegelungsstellung at a renewed closing of the door. This corresponds approximately to the situation according to FIG. 7 , The Vorverriegelungsstellung causes the closure element 2, in particular the door 1, remains closed after pressing, so it is locked. If now the closure element 1 in turn opened by pulling out the locking pin 9, so are the pivoting traps 41 of the individual locks 6 in their respective Vorverriegelungsstellung, with the result that the locking pin 9 could not occur.

Thus, since the respective locking pin 9 could not enter due to the Vorverriegelungsstellung the associated pivot latch 41 of each lock 6 at a renewed closing of the closure element 2, is at the respective pivot latch 41, preferably in addition to the respective lock pin 9 a ramp 157, 158 present, as is known from the FIG. 18 evident. Even if the pivot latch 41 is in the pre-locking position, it is possible to bring about by closing the closure element 2, a shrinkage of the locking pin 9 due to the inlet slope 157 and the inlet slopes 157, 158, respectively. As soon as electricity is available again, ie can be transferred from the emergency unlocking operation in the normal unlocking operation, the closure element 2, in particular the door 1, fully automatically brought into contact pressure position by automatically at each lock 6 and each closing element 7 of the already explained electrical locking operation takes place. Now, the normal electrical unlocking operation is possible again.
