Definitions

  • the present application relates to a device for locking a door leaf relative to a door frame according to the preamble of claim 1. Furthermore, the present application relates to a door according to the preamble of claim 12.
  • the device comprises a housing and two locking units, by means of which the door leaf can be locked relative to the door frame.
  • the housing can be a dedicated housing in which the remaining parts of the device are arranged. It is also conceivable that the housing is formed by a vertical profile of a door into which the device is installed.
  • an upper locking unit is arranged at an upper end of the device and a lower locking unit is arranged at a lower end of the device.
  • the device further comprises a coupling unit by means of which the two locking units are kinematically coupled. This is expressed in the fact that a transfer of one of the locking units from a locking position to an unlocking position causes a similar transfer of the other locking unit.
  • the locking position of a respective locking unit is characterized in that the locking unit is set up to interact with a corresponding locking element and thereby lock the door leaf relative to the door frame.
  • the locking units each comprise at least one locking element, which can in particular be designed in the form of an elongated bolt.
  • the device comprises a lock cylinder which is suitable for interacting with a coded key.
  • the locking cylinder can be operated manually, whereby a functional element of the locking cylinder can be moved between a closed position and an open position.
  • the locking cylinder can in particular be a commercially available locking cylinder.
  • the device comprises a transmission unit by means of which the movement of the functional element can be transmitted directly or indirectly to at least one of the locking units.
  • the device is set up so that at least one of the locking units can be moved from its respective locking position into its respective unlocking position by actuating the locking cylinder. Since the locking units are coupled to one another by means of the coupling unit as described above, this transfer of one of the locking units has a similar effect Transferring the other locking unit. This can be done with a time delay or, preferably, synchronously.
  • a door that includes a door leaf with such a device has at least two closing elements that are designed to interact with the locking elements of the locking units of the device, typically to form a positive lock.
  • the locking elements can engage in corresponding recesses in the closing elements and produce the positive locking described.
  • the respective door leaf is locked relative to a door frame of the door, so that it cannot be opened in the intended manner.
  • the engagement of at least one closing element with a respective locking element can be carried out automatically using an electrical locking device.
  • the locking device has an electric motor, by means of which a locking element can be moved relative to the door leaf and thereby brought into engagement with a locking element of the device.
  • a device of the type described above is already known in the prior art.
  • the device comprises two locking units, each of which has a locking element.
  • These locking elements which are formed by elongated bolts, are oriented parallel to one another and can each be transferred between a retracted position and an extended position.
  • the locking units are kinematically coupled by means of a coupling unit in such a way that the locking units can be moved synchronously between a locking position and an unlocking position.
  • a functional element of the lock cylinder engages in a form-fitting manner with a transmission unit, which is part of the coupling unit.
  • a transmission unit which is part of the coupling unit.
  • the coupling unit has a reversing element which is formed by a crank disk that can be rotated about an axis of rotation.
  • automatic locking systems are known. These are set up to automatically lock or unlock a respective door leaf relative to the associated door frame. It is known here that a motor-driven closing element of an electric locking device is moved relative to the door leaf and, in the course of this movement, engages with a locking element of the respective device, which is arranged on the same for locking the door leaf. Conversely, the door leaf is automatically locked and unlocked in reverse. Here, the closing element is moved by a motor in such a way that the engagement with the locking element is canceled, so that the door leaf can now be moved as intended relative to the door frame.
  • Manually operated devices are disadvantageous in that they do not allow integration into a locking system that works automatically. It is therefore necessary to always lock or, conversely, unlock the respective door leaf manually. Doors whose door leaves can be locked automatically are nevertheless disadvantageous in that they cannot be easily unlocked in the event of a malfunction in the respective drive or, for example, a power failure. It is therefore necessary for unlocking that the closing element is moved by a motor relative to the locking element in order to thereby release the door leaf. In the presence of a drive malfunction or in the absence of electrical power, such movement is prevented, requiring manual intervention. For this it is typically necessary to manually access the respective drive, which is typically installed in the door frame of the respective door. This involves a lot of effort and is correspondingly disadvantageous.
  • the present application is therefore based on the task of simplifying the operation of an automatically lockable door.
  • the device is characterized in that the coupling unit comprises a coupling element and two reversing elements that interact with the coupling element.
  • One of the reversing elements is assigned to one of the locking units.
  • the reversing elements can engage in a form-fitting manner with a corresponding form-fitting partner of the respective locking unit.
  • the coupling unit is set up to transmit a movement of one of the locking units to the coupling element by means of the reversing element assigned to the respective locking unit and to transmit the resulting movement of the coupling element to the locking unit assigned to it by means of the other reversing element. In this transmission, the kinematic coupling of the two locking units using the coupling unit can be seen in the device according to the invention.
  • a movement of at least part of a locking unit in particular a movement of its locking element, can be transmitted to the coupling element by means of the reversing element assigned to the locking unit, wherein preferably a direction of movement of the respective part of the locking unit is transmitted in the opposite manner to the coupling element by means of the reversing element.
  • a part of the upper locking unit is moved downwards in the direction of the locking cylinder, whereby the coupling element is moved upwards in the opposite direction as a result of the effect of the reversing element.
  • the device is further characterized in that the transmission unit is set up to transmit the movement of the functional element to at least one of the reversing elements. This is done in such a way that the reversing element is translationally movable relative to the housing as a result of an actuation of the locking cylinder.
  • the movement of the functional element which results from the actuation of the locking cylinder, can be transmitted to the transmission unit and ultimately to the reversing element by means of the transmission unit.
  • This mechanism causes the respective reversal element as such to be translational is moved relative to the housing, with a similar movement of these two components taking place as a result of the interaction of the reversing element with the coupling element and with the respective locking unit.
  • the mechanism of reversal that the reversal element typically brings about does not take place, ie the parts that interact with the reversal element, namely both a part of the respective locking unit and the coupling element, follow the translational movement of the reversal element.
  • the reversing element assigned to the upper locking unit can be moved translationally in a direction towards the locking cylinder by means of the transmission unit as a result of an actuation of the locking cylinder.
  • at least part of the locking unit assigned to the reversing element, in particular its locking element is also moved translationally towards the lock cylinder.
  • This movement can be equivalent to a "retraction" of the locking element, whereby it can lose its positive engagement with a locking element.
  • the upper locking unit is then in its unlocking position.
  • the coupling element which is connected to the reversing element, is also moved translationally in the same way due to this connection, following the translational movement of the reversing element.
  • the movements of at least the respective part of the locking unit and the coupling element therefore take place in the same direction, ie without a reversal by the reversing element.
  • the movement of the coupling element can then in turn be transmitted to at least part of the locking unit, in particular its locking element, by means of the other reversing element, which is assigned to the lower locking unit, with a direction of movement of the coupling element being reversed to the lower locking unit by means of the second reversing element.
  • the device according to the invention has many advantages.
  • the device thus enables a combination of manual unlocking of a respective door leaf with an automated locking system for the respective door.
  • at least one closing element can be driven by a motor and can enter into positive engagement (locking) or cancel it (unlocking) with at least one locking element of one of the locking units.
  • the resulting ease of use for such a door is therefore guaranteed.
  • manual unlocking can now be carried out using the device according to the invention To carry it out, all that is required is a key that matches the locking cylinder.
  • the locking cylinder in the middle of the door in terms of height, so that it can be easily reached without a user of the door having to bend down towards a locking cylinder arranged at foot height or stretch towards a locking cylinder arranged at head height.
  • the locking units can be transferred from their respective locking position to their respective unlocking position as desired through the interaction of the transmission unit with the coupling unit.
  • the reversing elements are formed by gears, each of which is rotatably mounted on axes of rotation.
  • the reversing elements are suitable for meshing with respectively assigned parts of the coupling element and the respective locking unit and in this way transmitting movements of the respective parts relative to one another.
  • the reversing elements in this embodiment are particularly well suited to transferring a movement of a respective contact partner, for example a part of a respective locking unit, inversely to the other contact partner, in particular the coupling element. In this way, it is particularly easy to transfer a movement, for example of a locking element of a locking unit, which is directed in a first direction, in an opposite manner to the coupling element, which then moves in a direction opposite to the locking element.
  • At least one of the locking units can assume three different positions, namely a receiving position in addition to the locking position and the unlocking position.
  • This can be particularly useful for the upper locking unit, since it can interact particularly easily with a motor-driven locking element, which is part of an electrical locking device is arranged in an upper part of a respective door frame.
  • the locking element of the locking unit In the receiving position, the locking element of the locking unit is extended in such a way that it protrudes beyond an upper end of the housing of the device and beyond an upper end of the door leaf equipped with the device and is designed to be gripped by the closing element of a respective locking device, in particular in a form-fitting manner to become.
  • the closing element In the course of the automated closing of the door, the closing element is moved downwards by a motor and grips the extended locking element. As a result, the locking unit is transferred from its receiving position into its locking position, with preferably a part of the locking unit, in particular the locking element itself or a separate switching element, being pushed a little way into the housing by means of the locking element.
  • This movement can be used to transfer the other locking unit, which can in particular be the lower locking unit, from its unlocking position to its locking position. It is therefore particularly easy to transfer the movement of the respective part of the locking unit, which is driven as a result of the interaction with the closing element, to the lower locking unit in the manner described above by means of the coupling unit and to effect a similar movement of the associated locking element.
  • the respective part of the locking unit for example its locking element or a switching element, is pressed by the locking element in the direction of the locking cylinder.
  • This movement is translated by means of the reversing element into an opposite movement of the coupling element, which moves correspondingly upwards, that is towards an upper end of the housing.
  • This movement of the coupling element is in turn translated by means of the other reversing element into a downward movement of at least part of the lower locking unit, in particular of its locking element, directed away from the locking cylinder.
  • the locking element of the lower locking unit can in turn engage in a locking element, which is present, for example, in the form of a receptacle which is formed in a door frame assigned to the door leaf. Both locking elements then engage with a locking element, so that the locking units are in their locking positions.
  • the transmission unit can be designed such that the reversing element, which is assigned to the upper locking unit, is in Direction is moved towards the lock cylinder, whereby a similar translational movement of these two parts takes place as a result of the positive coupling of the reversing element both with the coupling element and with at least part of the locking unit. It makes sense that at least the locking element of the upper locking unit is moved translationally towards the locking cylinder, so that it loses its positive engagement with the locking element without the locking element having to move as such.
  • the downward movement of the coupling element is in turn translated into an opposite movement of at least part of the lower locking unit, in particular its locking element, by means of the second reversing element, which cooperates with the lower locking unit.
  • This allows the locking element of the lower locking unit to be moved upwards and therefore towards the locking cylinder.
  • the locking element loses its engagement with the associated locking element. Therefore, both locking units are now in their respective unlocking positions, so that the door leaf can be moved relative to the door frame as intended.
  • At least one of the locking units cooperates with a spring which is braced at one of its ends against the respective locking unit and at its other end against a stop.
  • the spring is preferably designed as a compression spring. Both locking units preferably each work together with a spring.
  • the spring is advantageously pretensioned, preferably in such a way that the spring exerts an upward force on at least a part of the respective associated locking unit.
  • one of the locking units in particular the upper locking unit, can be moved into a receiving position, it is particularly advantageous if this locking unit cooperates with a pre-tensioned spring, which strives to hold the locking unit in its receiving position or to transfer it there.
  • This has the advantage that when a respective locking device is operated as intended, the locking unit is automatically returned to its receiving position when the engagement with the locking element of the locking device no longer occurs.
  • the associated stop against which the spring is supported, can be moved translationally to the housing in a similar way to the at least one reversing element, which can be moved translationally relative to the housing by means of the transmission unit when the lock cylinder is activated.
  • the stop can "move” with the reversing element, so that the reversing element and the stop do not move relative to one another move.
  • the locking unit as a whole is moved with the reversing element, so that the translational movement of the reversing element does not change a tension state of the spring and in particular the spring does not make the movement of the reversing element and/or the locking unit more difficult.
  • both locking units each interact with a spring
  • a clamping force with which one of the springs is preloaded exceeds the clamping force with which the other spring is preloaded.
  • the tension force of one spring exceeds the tension force of the other spring by at least 50%, preferably at least 75%, more preferably at least 100%.
  • the spring can be biased with a lower tension force, which is assigned to the locking unit, the associated reversing element of which can be moved in translation by means of the transmission unit as a result of a movement of the functional element of the locking cylinder.
  • the other spring can in particular cooperate with a stop which is designed to be stationary relative to the housing, the spring being able to indirectly support a movement of the reversing element as a result of the actuation of the locking cylinder.
  • the stronger spring is assigned to the lower locking unit, the locking element of which is retracted as a result of the actuation of the locking cylinder and thereby loses its engagement with the locking element corresponding to it.
  • the spring is preferably biased in such a way that this movement is supported, that is to say the spring at least indirectly exerts an upward force on the locking element.
  • the force of the spring is in line with the movement desired as a result of the actuation of the locking cylinder and supports this movement accordingly. This reduces mechanical resistance for starting the mechanism of the device when the locking cylinder is actuated, which makes it particularly easy for the user of the device to manually operate the locking cylinder using a key.
  • At least one of the reversing elements is formed by a rotatably mounted gear.
  • the kinematic coupling of the respective locking unit with the coupling element can be produced particularly easily, and the desired reversal of the movement of a respective part of the locking unit compared to the movement of the coupling element can also be carried out particularly easily.
  • both the coupling element and the respective reversing element interact Locking unit each include a toothed strip that meshes with the reversing element.
  • the device comprises a stroke increase, by means of which a stroke of the coupling element can be transferred to at least one of the locking units in an increased amount.
  • a stroke increase is particularly advantageous in order to move at least one locking element of a respective locking unit by a greater distance than a movement of the coupling element in the course of a transfer of the locking unit between its locking position and its unlocking position.
  • a movement of a locking element of a locking unit (in particular the upper locking unit) by, for example, 1 cm can thus be achieved by means of the Coupling unit can be transferred to the other locking unit (in particular the lower locking unit), whereby, due to the effect of the stroke increase, a path along which the other locking element moves is, for example, 3 cm.
  • a transfer of the locking units into their respective locking position can create a locking of the door leaf relative to the respective door frame, which is particularly protected against forcible opening of the door.
  • increasing the stroke can provide greater security against the door being broken into or other unauthorized access.
  • the door leaf is formed by a sliding door leaf of a sliding door.
  • a door leaf is typically mounted in a floor guide at its lower end.
  • a locking element of a lower locking unit that does not extend far enough into a door leaf retracted or retracted, would collide with the floor guide when opening the door leaf, with the result that the door leaf cannot be opened completely.
  • the "retraction movement" of the locking element i.e. its movement towards the locking cylinder, is of such an amount that the locking element is retracted far enough to avoid a collision with the floor guide.
  • the locking element is retracted so far that a lower end of the locking element is at a height above the floor guide. Accordingly, the door leaf can be opened further since there is no collision between the locking element and the floor guide, which in turn means that a clear opening of the door leaf of the sliding door in its open position is larger than if the door leaf could not be opened completely. This difference is particularly important in retrofitting situations in which a certain amount of clear opening must be maintained in order to meet the requirements for escape routes or the like.
  • the reversing element can in particular have two coaxially arranged toothed disks which have different diameters.
  • the diameter of a first toothed disk, which meshes with a toothed strip of the coupling element is smaller than the diameter of a second toothed disk, which meshes with a toothed strip of the locking unit assigned to the reversing element.
  • the transmission ratio between the movement of the coupling element and the movement of the respective part of the locking unit can be adjusted particularly easily via the diameters of the two toothed disks relative to one another.
  • the transmission unit comprises a translation element which is pivotably mounted about a pivot axis and which can be transferred directly or indirectly between a first and a second pivot position by means of the functional element.
  • This configuration is particularly advantageous if the functional element of the locking cylinder is moved in a circular path when the locking cylinder is actuated, as is common with most locking cylinders.
  • the functional element can be moved along an arc of a circle in an angular range of at least 135°, preferably at least 150°, more preferably 180°. This movement of the functional element is at least indirect by means of the translation element translatable.
  • the translation element can cooperate with a transmission rod of the transmission unit, which is guided along a linear axis as a result of the pivoting of the translation element about the pivot axis.
  • the movement of the functional element can be translated into a linear movement of the transmission rod.
  • the translation of the movement of the functional element by means of the translation element can in particular contribute to the fact that a force that has to be applied manually using a key to transfer the locking cylinder between its closed position and its open position remains so low that the locking cylinder can be easily operated. This also reduces the risk of the respective key bending or, in the worst case, breaking off.
  • the transmission unit has a transmission element that interacts directly with the functional element.
  • the transmission element is designed to be displaced by the functional element during the actuation of the locking cylinder and thereby to be moved translationally relative to the housing.

  • a channel can be formed in the transmission element, in particular in the form of a milling, in which a pin connected to the translation element is guided in a form-fitting manner.

In other words, the door leaf is locked in this state. Accordingly, the locking element is in such a position for engagement with the closing element that it can be gripped by the closing element. In particular, it is provided that the locking element protrudes beyond an upper end of the door leaf facing the locking device.

  • the reversing elements 13 , 14 are connected to one another by means of the coupling element 12 .
  • the reversing elements 13 , 14 are each formed by gears which are rotatably mounted about axes of rotation 31 , 32 .
  • the reversing element 13 which is assigned to the upper locking unit 4 , is mounted on a transmission unit 8 , which is rod-shaped in the example shown.
  • the transmission unit 8 is movable in translation relative to the housing 3 and cooperates with a locking cylinder 7 , which can be operated manually using a key, not shown. Accordingly, the lock cylinder 7 has a recess into which a correspondingly coded key can be received in a form-fitting manner.
  • the transmission unit 8 in the example shown is moved translationally relative to the housing 3 in a vertically downward direction, whereby the reversing element 13 mounted on the transmission device 8 is also carried along.
  • the operation of the device 1 is as follows:
  • the door leaf 2 which is equipped with the device 1 , is not locked, ie it can be moved relative to a door frame as intended.
  • the corresponding condition of the device 1 is particularly good based on Figure 1 recognizable.
  • the upper locking unit 4 is in a receiving position in which its locking element 9 is extended, so that an upper end portion of the locking element 9 protrudes beyond an upper end of the housing 3 .
  • the lower locking unit 5 is in an unlocking position in which its locking element 10 is completely retracted into the housing 3 .
  • the upper locking unit 4 is suitable for interacting with a locking element of an electrical locking device, which grips the locking element 9 .
  • a closing element is not shown in the example shown.
  • this embodiment causes the coupling element 12 to be moved upwards in the opposite direction as the locking element 9 is retracted, that is to say it moves in the direction of the upper end of the housing 3 .
  • this movement of the coupling element 12 is transmitted to the lower locking unit 5 and in particular its locking element 10 .
  • a reversal of direction also takes place, so that the locking element 10 is moved in a downward direction, ie away from the locking cylinder 7 .
  • the locking element 10 can also be equipped with a toothed strip, so that it can mesh particularly easily with the reversing element 14 designed as a gear.
  • the locking element 10 of the lower locking unit 5 is extended so that it partially protrudes beyond a lower end of the housing 3 .
  • the lower locking element 10 is set up to engage with a corresponding locking element, which can be formed, for example, on or in the respective door frame.
  • Both locking units 4 , 5 are now in their locking position, in which they each interact with locking elements and thereby fix the door leaf 2 relative to the door frame.
  • the locking element of the electrical locking device is raised and the positive engagement with the locking element 9 of the upper locking unit 4 is thereby released.
  • the locking element 9 can track the movement of the closing element and the upper locking unit 4 can thereby be moved back into its receiving position. Due to the effect of the coupling unit 6, such a movement of the locking element 9 means a movement of the locking element 10 of the lower locking unit 5 in the same direction, so that said locking element 10 is retracted into the housing 3 .
  • the door leaf 2 is then unlocked again and can be moved relative to the door frame.
  • both said locking element 9 and said coupling element 12 are moved downwards in translation relative to the housing 3 .
  • the reversing element 14 which is assigned to the lower locking unit 5 , remains stationary relative to the housing 3 and is not influenced by the movement of the transmission unit 8 .
  • the coupling element 12 moves relative to the reversing element 14 . Due to the accompanying mechanics, this results in the locking element 10 of the lower locking unit 5 being moved in the opposite direction, ie upwards here.
  • the device 1 which is arranged here in a door leaf 2 , includes an upper locking unit 4 , which is equipped with a locking element 9 . Furthermore, the device 1 includes a lower locking unit 5 , which is equipped with a locking element 10 . Furthermore, a coupling unit 6 is present, which includes two reversing elements 13 , 14 and a coupling element 12 , the latter being designed in the form of an elongated push rod.
  • the individual assemblies of the device 1 are arranged within the housing 3 . Approximately in the middle of the device 1, it includes a locking cylinder 7 , which includes a functional element 11 .
  • the lock cylinder 7 cooperates with a transmission unit 8 , by means of which a movement of the functional element 11 can be transferred to the reversing element 13 , which is assigned to the upper locking unit 4 .
  • This is done in such a way that the reversing element 13 is movable in translation relative to the housing 3 as a result of the actuation of the locking cylinder 7 . In the example shown, this occurs in the sense of a downward movement of the reversing element 13 , that is, in the direction of the locking cylinder 7 .
  • the closing element 30 is lowered by means of an electric drive 29 , the locking element 9 of the upper locking unit 4 being gripped in a form-fitting manner. As in Figure 5 shown, this causes the locking element 9 to be “pressed” at least somewhat into the housing 3 of the device 1 . This results in a spring 16 connected to the upper latch unit 4 being compressed.
  • the spring 16 which is formed by a preloaded compression spring, is supported against a stop 18 . The spring 16 ensures that the locking element 10 is extended again should the closing element 30 be raised again. As a result of the downward movement of the closing element 30, the upper locking unit 4 is now in its locking position.
  • the "pressing in” of the locking element 9 leads to a reverse upward movement of the coupling element 12 , which is raised by the action of the reversing element 13 .
  • both the upper locking unit 4 and the coupling element 12 each work together with toothed strips 20 , 22 , which mesh with the reversing element 13 .
  • the upward movement of the coupling element 12 leads via the reversing element 14 , which is assigned to the lower locking unit 5 , correspondingly to a downward movement of the locking element 10 of the lower locking unit 5 .
  • the reversing element 14 is equipped with a stroke increaser 27 .
  • the reversing element 14 comprises two coaxial toothed disks, the diameter of a first toothed disk not visible in the figures, which meshes with a toothed strip 23 of the coupling element 12 , being smaller than the diameter of the second Toothed disc that meshes with a toothed strip 21 of the lower locking unit 5 .
  • the locking element 10 is extended beyond a lower end of the door leaf 2 and thereby engages with a stationary closing element 37 , which can be designed in particular in the form of a receptacle formed in a door frame of the door leaf 2 .
  • the two locking units 4 , 5 are now each in their locking position.
  • the locking cylinder 7 can now be used to manually unlock the door leaf 2 .
  • This is suitable for receiving a correspondingly coded key, with the functional element 11 being guided along a circular arc section in an angular range of approximately 180° as a result of an actuation of the locking cylinder 7 .
  • This movement of the functional element 11 results in the reversing element 13 , which cooperates with the upper locking unit 4 , being moved downwards in translation relative to the housing 3 .
  • a transmission unit 8 is responsible for this transmission of the movement of the functional element 11 to the reversing element 13 , which cooperates with both the locking cylinder 7 and the reversing element 13.
  • the transmission unit 8 includes a transmission element 26 , a translation element 25 , a transmission rod 36 and a carrier element 15 .
  • the translation element 25 is mounted on the housing 3 so that it can pivot about a pivot axis 24 and interacts with the transmission rod 36 in a form-fitting manner.
  • the transmission rod 36 is connected at its end facing away from the lock cylinder 7 to the carrier element 15 , which carries the reversing element 13 .
  • the transmission rod 36 and therefore the carrier element 15 can be moved linearly up and down relative to the housing 3 as a result of a pivoting movement of the translation element 25 .
  • the functional element 11 engages directly with the transmission element 26 , which is mounted in the housing 3 in a guided, movable manner.
  • the transmission element 26 has a milling in which a guide pin of the translation element 25 is mounted.
  • the transmission element 26 is raised against the action of a spring 34 , ie displaced in a direction facing away from the lock cylinder 7 .
  • the transmission element 26 is pushed back again by the action of the spring 34 , so that it is ultimately in its starting position, but the functional element 11 is rotated 180°.
  • the locking element 10 is drawn into the door leaf 2 and loses its positive engagement with the closing element 37 .
  • the locking element 9 loses its positive engagement with the closing element 30 assigned to it in the course of the downward movement of the reversing element 13 .
  • the locking units 4 , 5 are now each in their unlocked position, so that the door leaf 2 can be moved relative to the door frame.
  • a tensioning force of the spring 17 which cooperates with the lower locking unit 5 , is greater than a tensioning force of the spring 16 , which interacts with the upper locking unit 4 .
  • the tension force of the spring 17 can be twice as large, preferably three times as large, as the tension force of the spring 16 . This simplifies the operation of the lock cylinder 7 in the manner described.
  • the upper locking unit 4 includes a locking element 9 and a separate switching element 33 .
  • the electric locking device 28 which includes an electric drive 29 , further includes a locking element 30 , which can be lowered towards the locking element 9 by means of the drive 29 . This ensures that the locking element 9 is gripped in a form-fitting manner by the locking element 30 , but the locking element 9 as such is not moved towards the locking cylinder 7 of the device 1 . Nevertheless, as a result of the movement of the closing element 30 , the switching element 33 is actuated, which is "pressed” in the direction of the locking cylinder 7 .
  • the switching element 33 cooperates with a toothed strip 20 , which is connected to the Reversing element 13 , which is assigned to the upper locking unit 4 , meshes.
  • the reversing element 13 further meshes with the coupling element 12 of the coupling unit 6 via a toothed strip 22 , so that the downward movement of the switching element 33 causes a corresponding upward movement of the coupling element 12 .
  • the coupling element 12 is formed here by a pull rope. This movement is in turn transmitted in the manner described via the further reversing element 14 to the lower locking unit 5 , so that its locking element 10 is extended.
  • this movement is increased by a stroke enlargement 27 , for which a movable gear 35 , a fixed toothed bar 38 and a movable toothed bar 39 are used.
  • a stroke enlargement 27 for which a movable gear 35 , a fixed toothed bar 38 and a movable toothed bar 39 are used.
  • the movable gear 35 meshes with the fixed toothed bar 38 , which is fixed relative to the housing 3 .
  • the movement of the gear 35 has a direct effect on the locking element 10 of the lower locking unit 5 , which is kinematically coupled to the locking element 10 via the movable toothed bar 39 .
  • the movable gear 35 is arranged on a support element 40 , which moves along the fixed toothed bar 38 in accordance with the translational movement of the movable gear 35 .
  • the toothed bar 21 of the lower locking unit 5 is formed on this support element 40 , the toothed bar 21 meshing with the toothed bar 23 of the coupling unit 6 via the reversing element 14 , analogously to the description above.
  • the interaction of the reversing element 14 with the toothed bar 21 and the movable gear 35 with the movable toothed bar 39 leads, as desired, to the stroke increase, which here provides a ratio of 1:2.
  • both the upper locking unit 4 and the lower locking unit 5 are each transferred into their locking position, with the locking element 9 of the upper locking unit 4 with the locking element 30 and the locking element 10 of the lower locking unit 5 with it engage in a form-fitting manner with the further closing element 37 .
  • Figure 8 This is particularly clear from: Figure 8 .
  • the reversing element 13 is mounted on this support element 15 , so that a translational movement of the transmission rod 36 leads to a corresponding movement of the support element 15 and thus of the reversing element 13 .
  • the reversing element 13 is moved towards the locking cylinder 7 , with the locking element 9 of the upper locking unit 4 arranged on the support element 15 being “retracted”.
  • the locking element 9 loses its engagement with the closing element 30 , so that the upper locking unit 4 is now in its unlocking position.
  • the actuation of the locking cylinder 7 and the resulting movement of the functional element 11 are accordingly transmitted indirectly to the locking units 4 , 5 by means of the transmission unit 8 in such a way that they are transferred from their locking positions to their unlocking positions.
  • the coupling element 12 is also moved downwards in the manner described. Since the coupling element 12 is designed here as a rope and as such is flexible, the movement of the upper toothed bar 21 of the coupling element 12 is not transmitted to the lower toothed bar 22 . Instead, the coupling element 12 folds and thereby gives the lower toothed bar 22 a freedom of movement for downward movement, that is to say in a direction away from the lock cylinder 7 .
  • the door leaf 2 is displaced relative to the door frame in order to open the door.
  • the door Around the To guide movement of the door leaf, the door has a floor guide 41, which is based on Figure 10 results.
  • the floor guide is arranged at a lower end of the door directly on a door frame of the door. It protrudes a little way beyond a floor, which means that there is fundamentally a risk of collision with the locking element 10 of the lower locking unit 5 of the device 1 , which interacts with the door leaf 2 .
  • the device has a stroke increaser 27 , which has the technical effect that a stroke of the locking element 10 in the course of the transfer of the lower locking unit 4 from its locking position to its unlocking position is comparatively large.
  • the stroke increaser 27 can have a ratio of 1:3, so that a movement of the locking element 9 of the upper locking unit 4 is tripled in amount when transmitted to the locking element 10 of the lower locking unit 5 .
  • the effect of the stroke increase 27 causes the locking element 10 to move so far in the direction of it Figure 10 Not shown locking cylinder 7 of the device 1 is raised so that a lower end 42 of the locking unit 10 is located above the floor guide 41 when the locking unit 4 is present in its unlocking position, that is to say at a height level above the floor guide 41 . This condition is in Figure 10 illustrated.
  • a collision between the locking element 10 and the floor guide 41 is therefore avoided, which makes it possible to completely open the door leaf 2 and thereby completely release a clear width of the door. If the locking element 10 could only be raised to a lesser extent and then collided with the floor guide 41 , the door leaf 2 could not be fully opened, so that the clear width of the door would effectively be smaller. This is particularly disadvantageous in cases where, due to applicable regulations, there must be a certain clear width of an opened door.
