Description

[0001] The invention relates to a deadbolt lock according to the features of the preamble of claim 1.

[0002] DE 10 2016 108 706 A1 discloses a drive bolt lock with an upper drive bolt rod and a lower drive bolt rod, which can be operated both motor-driven and manually. This lock has two actuating devices: a motor-driven actuating device and a mechanical manual actuating device. To enable the interaction of these two different actuating devices, several coupling elements are provided. Overall, this lock has a relatively complex structure and functional sequence.

[0003] Document EP 3 543 436 B1 also discloses a shoot-bolt lock with an upper shoot-bolt bar and a lower shoot-bolt bar. This shoot-bolt lock can also be operated by an electric motor or manually. A central slide plate is provided to operate the lock components of this lock. To prevent jamming between the mechanical and motorized drive, the motor or motor gear is disengaged from the central slide plate in the rest position.

[0004] US 2018 / 0155962 A1 discloses a lock with a multi-point locking system. The lock is manually operated and has a motorized drive located outside the lock housing.

[0005] EP 3 543 437 A1 describes a manually and motor-operated espagnolette lock. Both the motor drive and the lock follower act on the slide plate to operate the lock. A slide plate operates both the bolt ejector and the retractor slides for the espagnolette bars.

[0006] The present invention is based on the object of providing a deadbolt lock that, while being structurally simple, can be operated both mechanically and by motor, yet offers a high degree of functional reliability. In particular, interference with the motor and manual mechanical drive should be prevented. Preferably, manual mechanical unlocking of the deadbolt lock should be possible at any time.

[0007] This object is achieved according to the invention by a deadbolt lock having the features of claim 1.

[0008] According to the invention, a shoot bolt lock for a passive leaf of a double-leaf door is proposed, comprising a lock housing, a faceplate, and an upper retraction slide for moving an upper shoot bolt rod and a lower retraction slide for moving a lower shoot bolt rod, wherein the upper retraction slide and the lower retraction slide are connected to one another via a two-armed reversing lever pivotally mounted in the lock housing, as well as a slide plate movable parallel to the faceplate and a lock nut with nut lever rotatably mounted in the lock housing in order to manually unlock the two shoot bolt rods, as well as a motor for unlocking the two shoot bolt rods in a motor-driven manner.It is important that the motorized unlocking and the manual unlocking are separated in such a way that with the motorized unlocking the motor acts directly on the slide plate via a motor gear in order to move it linearly along the faceplate and the slide plate cooperates with the bell crank to pivot it in order to unlock the two espagnolette bars, and that with the manual unlocking the nut lever acts directly on the lower retraction slide or the upper retraction slide in order to unlock the two espagnolette bars.

[0009] One advantage of separating the motorized drive from the mechanical drive is that each drive has its own line of action to unlock the espagnolette lock, thus preventing interference between the drives. In particular, the direct action of the follower lever on the lower retracting slide or the upper retracting slide ensures that when the espagnolette lock is manually unlocked, the connecting rods are retracted directly, without any intervening lock components hindering the unlocking process. Because the motor acts on a different component of the lock mechanism than the lock follower, namely the slide plate, different movement sequences can be easily implemented between motorized and manual unlocking.

[0010] Preferably, a locked position of the espagnolette lock is understood to mean a position in which the two espagnolette bars are excluded upwards and downwards from the lock housing in such a way that the upper espagnolette bar engages in a locking receptacle on the door frame and the lower espagnolette bar engages in a locking receptacle on the floor of the door.

[0011] In particular, the unlocked position of the espagnolette lock is understood to mean a position in which the two espagnolette bars are retracted into the lock housing in such a way that the espagnolette bars no longer interact with a locking receptacle, so that the passive leaf can be opened.

[0012] In particular, in the unlocked position of the espagnolette lock, the latch slide and / or bolt slide of the espagnolette lock ensure that locking elements of an active leaf lock are pushed back, so that in the unlocked position both leaves of the double-leaf door, i.e. both the passive leaf and the active leaf, can be opened.

[0013] In particular, a retractable slide is understood to be a component that can be moved linearly within the lock housing, preferably parallel to the faceplate, and which has a connection for a deadbolt. A retractable slide can predominantly be designed as a flat or plate-shaped component.

[0014] In particular, a slide plate is understood to be a predominantly flat or flat component that can be moved linearly within the lock housing, preferably parallel to the face plate. In particular, the slide plate connects several movable elements of the espagnolette lock. For this purpose, the slide plate can have one or more guides. Likewise, or alternatively, the slide plate can have one or more pins or rollers, each of which establishes a connection to a movable element of the lock mechanism.

[0015] In particular, a lock housing is understood to be a housing in which the components of the espagnolette lock are housed. The lock housing preferably has recesses in the area of ​​the face plate that allow the passage of locking elements, such as the lock bolt and / or latch. Furthermore, the lock housing can have recesses for espagnolette bars on its upper and lower narrow sides.

[0016] Preferably, the espagnolette lock has only a single lock housing. In particular, the motor and motor gear are located within the lock housing. This allows for a compact and space-saving lock design.

[0017] In particular, one embodiment can provide that, to unlock the nut levers, the lower retraction slide or the upper retraction slide is acted upon in the same direction, in particular an unlocking direction, in which the motor acts upon the slide plate for unlocking. This results in a simpler structure, since the number of deflection elements or deflection levers can be reduced.

[0018] In particular, it can be provided that the motor gear pushes the slide plate in the unlocking direction by means of a one-sided contact, wherein the one-sided contact is open in the unlocking direction. One-sided contact can be understood, for example, that the motor gear has a pin in the output that acts on a contact surface of the slide plate, or that the slide plate has a pin that is pushed by a contact surface of the motor gear. It is important that the contact is one-sided so that on the other side there is no obstruction to the movement of the slide plate, so that the slide plate can move away from the contact in the unlocking direction. This means that the slide plate can be moved further in any position of the motor or motor gear, for example by manual mechanical unlocking, without the motor or motor gear causing a jamming situation.

[0019] Preferably, it can be provided that the slide plate has a slide pin or a slide roller, wherein the slide pin or the slide roller runs on a control curve of the reversing lever in order to pivot the reversing lever. The movement of the reversing lever can be predetermined via the control curve of the reversing lever. In particular, the rotational speed of the reversing lever can be varied depending on the position of the reversing lever and / or the slide plate. This makes it possible to implement a different movement sequence between the motor drive and the manual drive. For example, it can be provided that when unlocking via the lock nut, the reversing lever runs ahead of the slide pin or the slide roller and thus comes out of operative engagement with the slide plate, in particular by the control curve of the reversing lever lifting off the slide pin or the slide roller.

[0020] This allows the espagnolette rods to be actuated more quickly during manual unlocking than during motorized unlocking. This allows for safe and quick opening of the door in an emergency with manual unlocking. It also ensures that the motorized drive cannot block the unlocking during manual unlocking. Neither the motorized gear nor the motor-driven slide plate can prevent the bell crank from moving. This increases the functional reliability of the espagnolette lock.

[0021] In one embodiment, the lower retraction slide or the upper retraction slide can be directly connected to the bell crank via an engagement point in order to pivot the bell crank, in particular to pivot the bell crank during manual unlocking. Advantageously, a direct connection of the retraction slides via the bell crank creates a positive guide for the two retraction slides relative to each other, so that when one of the retraction slides is driven, the other retraction slide is automatically actuated in the opposite direction to unlock the espagnolette lock.

[0022] In particular, it can be provided that the point of action of the lower feed slide acts on the same arm of the two-armed reversing lever as the slide pin or the slide roller of the slide plate, or that the point of action of the upper feed slide acts on the other arm of the two-armed reversing lever as the slide pin or the slide roller of the slide plate.

[0023] In one embodiment, it can be provided that, at least in a locking position, the effective lever between the pivot point of the reversing lever and the point of action of the upper or lower retraction slide is greater than the effective lever between the pivot point of the reversing lever and the slide pin or the slide roller of the slide plate. This allows the distance traveled by the reversing lever to be greater when the upper or lower retraction slide is acted upon than when the reversing lever is acted upon by the slide pin of the slide plate.

[0024] In particular, it can be provided that the control curve of the bell crank is designed in such a way that during motorised unlocking starting from the locked position, the rotation rate of the bell crank is lower, at least at the beginning of the motorised unlocking than towards the end of the motorised unlocking. This can ensure that at the beginning of the motorised unlocking, the espagnolette rods are moved in the unlocking direction, but at a very low speed. This means that the inactive leaf remains locked for a relatively long time during motorised unlocking. In particular, it remains locked until the active leaf is moved into the unlocked position via the bolt slides or the latch slides of the espagnolette lock, so that the active leaf can be opened as long as the inactive leaf is still locked.

[0025] In order to achieve a compact design of the espagnolette lock, it can be provided that the axis of rotation of the bell crank runs parallel to the axis of rotation of the lock nut and the control curve of the bell crank is arranged on a side surface of the bell crank facing away from the lock nut.

[0026] In order to reduce the forces required to actuate the espagnolette lock, it can be provided that the follower lever has a pin or a roller by means of which it interacts directly with the lower retraction slide or the upper retraction slide, in that the lower retraction slide or the upper retraction slide has a slide stop surface for the pin or the roller, such that the follower lever acts on, in particular pushes, the lower retraction slide or the upper retraction slide into an unlocking position via the pin or the roller during manual unlocking.

[0027] In order to reduce the influence between motorized and manual operation of the espagnolette lock, it can also be provided that the slide stop surface of the lower retracting slide or the upper retracting slide is disengaged from the pin or the roller of the nut lever during motorized unlocking, in particular that the slide stop surface lifts off the pin or the roller of the nut lever.

[0028] In particular, it can be provided that the slide stop surface of the lower retraction slide or the upper retraction slide is part of a stop curve on which the pin or the roller of the nut lever runs when the upper or lower retraction slide comes out of operative engagement with the pin or the roller of the nut lever during motorized unlocking.

[0029] In one embodiment, the motor can be designed as a linear motor, or the motor gear can be designed as a spindle drive to drive the slide plate parallel to the face plate. The motor can be designed, in particular, as an electric motor, for example, as an electric linear motor, or as a motor that drives a rotating shaft connected to a spindle drive to create a linear movement by means of a spindle and a spindle nut.

[0030] Preferably, the motor gear has a stop surface in the output shaft that engages a stop pin of the slide plate to motor-drive the slide plate into an unlocking position. This also allows the motor gear to be open on one side relative to the slide plate, so that the slide plate can disengage from the motor gear at any time in the unlocking direction and cannot be blocked by it.

[0031] For particularly good guidance of the slide plate, one embodiment can provide that the motor gear in the output has two stop surfaces, each of which is in contact with a stop pin of the slide plate in order to motor-drive the slide plate into an unlocking position.

[0032] In particular, it can be provided that the two stop pins of the slide plate are arranged on different sides of the motor output, in particular on different sides of the spindle drive in such a way that a spindle of the spindle drive runs between the two stop pins. In this way, the force of the spindle drive is evenly distributed between the two stop pins to the left and right of the spindle in such a way that no one-sided torque acts on the slide plate and it is moved linearly, i.e. parallel to the forend in the lock housing, without the motor being able to exert lateral pressure on the slide plate. This has the advantage that the frictional forces when the slide plate moves are also minimized and the risk of jamming is likewise minimized.

[0033] In particular, it can be provided that during manual unlocking, the slide plate disengages from the stop surface(s) of the motor output, in particular that the stop pin of the slide plate lifts off the stop surface of the motor output, or that the stop pins of the slide plate lift off the stop surfaces of the motor output. This allows the motor output to be decoupled from the slide plate during manual unlocking, so that no movement of the motor or motor output can be inhibited.

[0034] Preferably, the espagnolette lock can have a bolt ejector for actuating a lock bolt of an active leaf lock and / or a latch ejector for actuating a lock latch of an active leaf lock. The bolt ejector and / or latch ejector can be actuated via a bolt slide lever in the case of motorized unlocking and also in the case of unlocking by means of a lock follower.

[0035] In one embodiment, a two-armed bolt slide lever can be rotatably mounted concentrically to the lock follower. The first arm of the two-armed bolt slide lever interacts with the slide plate via a slotted guide, and the second arm of the two-armed bolt slide lever interacts with a bolt ejector to move the latter between an unlocked position, protruding from the lock housing, and a locked position, retracted into the lock housing. The bolt slide lever actuates the bolt ejector of the espagnolette lock to move a lock bolt of an active leaf lock from the locked position to the unlocked position.

[0036] In particular, the follower lever can be provided with a driver for the bolt slide lever, which, when the lock follower is rotated, engages the bolt slide lever to move it into an unlocking position. This ensures that, during manual unlocking using the lock follower, the bolt slide lever also actuates the bolt ejector to unlock an active leaf lock.

[0037] Preferably, the bolt slide lever can further be provided to drive a latch ejector via a latch reversing lever, moving the latch ejector between an unlocked position and a locked position. This also makes it possible to unlock the latch of an active sash lock. The bolt slide lever is actuated, in particular, during both motorized and manual unlocking, so that the bolt ejector and the latch ejector are reliably actuated in both cases.

[0038] In order to enable a compact construction, it can be provided in one embodiment that the nut lever is arranged in the lock housing between the lower retraction slide and the deflection lever in a plane parallel to the lock base and / or the lock cover of the lock housing.

[0039] To ensure trouble-free and convenient operation, a spring drive can be provided. The two drive rods are retracted into an unlocked position, either motor-driven or manually operated by the lock follower, while the spring drive is charged. The spring drive can assist in moving the espagnolette lock from the unlocked to the locked position or serve as the sole drive for locking the espagnolette lock.

[0040] In a preferred embodiment, it can be provided that the spring drive has two springs, wherein one of the springs acts on the slide plate and the second spring acts on the lower feed slide or the upper feed slide, in particular that the springs are designed as helical springs and / or compression springs.

[0041] The inventive concept also includes a locking device for a double-leaf door comprising a passive leaf and a moving leaf, wherein the passive leaf has a shoot bolt lock according to one of the preceding embodiments and the moving leaf has a panic lock with a bolt and / or a latch, and wherein the shoot bolt lock has a bolt ejector and / or a latch ejector in order to unlock the bolt and / or the latch of the panic lock in a motorized or manually driven manner.

[0042] The espagnolette lock according to the invention is intended for use with double-leaf doors. The active leaf, or active wing, can be unlocked when the inactive leaf, or passive wing, is opened. For this purpose, the espagnolette lock can be equipped with corresponding bolt slides and / or latch slides to unlock the locking elements of the active wing lock. This has the advantage that in the event of an emergency opening of the double-leaf door, only one leaf, namely the inactive leaf, needs to be operated to open both leaves of the double-leaf door. A further advantage is that the active leaf can be opened while the inactive leaf remains locked by means of the espagnolette lock and the espagnolette rods. This provides the advantage of convenient operation of the double-leaf door and, in an emergency, the possibility of rapid escape through the double-leaf door.

[0043] The espagnolette lock according to the invention can preferably also be used in emergency exits to enable rapid escape in the event of an emergency or panic. The espagnolette lock can be designed as a manual espagnolette lock that is operated manually. In another embodiment, the espagnolette lock can also be designed as a motor-driven espagnolette lock, i.e., the espagnolette bolts and / or bolt ejectors can be actuated by a motor. Combined manual and motor-driven operation of the espagnolette lock is also possible.

[0044] In particular, the espagnolette lock can be designed according to DIN EN 179 to enable use in fire and smoke protection doors. Alternatively and / or additionally, the espagnolette lock according to the invention can also be designed according to DIN EN 1125 to enable use in panic doors.

[0045] Further embodiments and examples of the espagnolette lock according to the invention are shown in the figures and described below. They show: Fig. 1: a locking device on a double-leaf door comprising a drive bolt lock according to the invention; Fig. 2: a schematic representation of the drive bolt lock in a locked position; Fig. 3: the drive bolt lock according to Figure 2 in a motor-unlocked position; Fig. 4: the cut-out slide plate with the bell crank of the deadbolt lock; Fig. 5: the connection of the bell crank to the lower retraction slide; Fig. 6: the connection of the bell crank to the upper retraction slide; Fig. 7: the deadbolt lock according to Figure 2in a manually unlocked position; Fig. 8: the connection of the nut lever to the lower retraction slide; Fig. 9: a schematic representation of the interaction between the bolt slide and the latch deflection lever; Fig. 10: the latch ejector with the latch deflection lever.

[0046] The figures illustrate exemplary embodiments of the espagnolette lock 2 according to the invention. These are not intended to be limiting. In the figures, components with equivalent functions are provided with the same reference symbols. A person skilled in the art can combine the various embodiments shown with one another, based on their technical skills, within the scope of protection defined by the claims, without departing from the spirit of the invention.

[0047] The Fig. 1shows a schematic representation of a locking device 1 on a double-leaf door 11. The double-leaf door 11 has a fixed leaf 14 and a moving leaf 15. The fixed leaf 14 is pivotally mounted on a door frame 12 of the double-leaf door 11 via hinges 131, 132. Likewise, the moving leaf 15 is pivotally mounted on the door frame 12 of the double-leaf door 11 via hinges 133, 134.

[0048] The active leaf 15 has a panic lock 16, which is operated via a door handle 17. The panic lock 16 is designed as a self-locking panic lock and has an automatically extending bolt and a latch. The inventive espagnolette lock 2 is accommodated in the passive leaf 14. The espagnolette lock 2 has an upper espagnolette bar 24 and a lower espagnolette bar 25. In the illustration of the Fig. 1the espagnolette lock 2 is locked, i.e., the two espagnolette rods 24 and 25 are extended and lock the inactive leaf 14 to the door frame 12 and the floor. The espagnolette lock 2 can be manually unlocked via a lock nut 23. Furthermore, the espagnolette lock 2 has a motor, by means of which the espagnolette lock 2 can be unlocked by motor. The connecting cable 18 of the motor is guided through the inactive leaf 14 and, by means of a flexible cable transition 19, over the door frame 12. The espagnolette lock 2 has a latch receiving space and a bolt receiving space, into which the locking elements of the panic lock 16, i.e., the latch and the bolt, can engage. The panic lock 16 can be unlocked via the latch slide or bolt slide by means of the espagnolette lock 2.When the espagnolette lock 2 is unlocked, the panic lock 16 is unlocked first, allowing the active leaf 15 to be opened, while the inactive leaf 14 is still locked via the espagnolette bars. Only when the espagnolette lock 2 is completely unlocked can the inactive leaf 14 be opened.

[0049] In the Fig. 2 The espagnolette lock 2 is shown schematically in the locked position. The espagnolette lock 2 has a lock housing 21, on the front of which a face plate 22 is arranged. Furthermore, the lock housing 21 has a lock base 211 and a lock cover, as well as side walls closing the side surfaces of the lock housing 21. The components of the espagnolette lock 2 are accommodated within the lock housing 21. For clarity, Fig. 2The lock cover has been removed or shown transparently. Opposite the lock cover (not shown) is the lock base 211. The lock base 211 holds components of the lock mechanism, for example the lock follower 23. The espagnolette lock 2 has an upper espagnolette rod 24 and a lower espagnolette rod 25. The espagnolette rods are each connected to the mechanism of the espagnolette lock 2 via retraction slides 241 and 251. The upper retraction slide 241 is connected to the upper espagnolette rod 24. The lower retraction slide 251 is connected to the lower espagnolette rod 25.

[0050] Furthermore, the espagnolette lock 2 comprises a bolt ejector 5 and a latch ejector 4. In the Fig. 2In the locked position shown, the espagnolette bars 24, 25 are extended upwards and downwards from the lock housing 21 to their maximum extent. The latch ejector, like the bolt ejector 5, is retracted into the lock housing 21. This creates a receiving space in front of the latch ejector 4 and the bolt ejector 5, into which a latch or a bolt of an active leaf lock can engage. This allows the espagnolette lock 2 to be locked not only via the espagnolette bars 24, 25, but also via the locking elements of an active leaf lock.

[0051] Furthermore, the espagnolette lock 2 comprises a motor drive comprising an electric drive motor 3 with a motor output 31, which is designed as a spindle drive. The motor output 31 comprises a spindle 32 and a spindle nut 33. The spindle nut has two stop surfaces 331 and 332, each of which interacts with a pin of a slide plate 27. The slide plate 27 is mounted in the lock housing 21 parallel to the forend 22 for linear displacement and can be actuated by the motor 3 or the spindle drive 31. In the locked position shown, the slide plate 27 is arranged in its lower position. The spindle nut 33 is also arranged in the lower position.

[0052] Furthermore, the espagnolette lock 2 comprises a spring drive 6 comprising two compression springs 61 and 62. The spring drive 6 is charged when the espagnolette lock is unlocked. When locked, the spring drive 6 acts to move the espagnolette lock 2 into the locked position.

[0053] Furthermore, the espagnolette lock 2 has a lock nut 23, via which the espagnolette lock 2 can be unlocked manually or mechanically. The lock nut 23 is connected in a rotationally fixed manner to a nut lever 231. The nut lever 231 has a driver 232 on its upper side for actuating or driving a bolt slide lever 28.

[0054] The bolt slide lever 28 is rotatably mounted concentrically to the lock nut 23 and has two interconnected bolt slide arms. The first bolt slide arm 281 is arranged above the lock nut 23 and the second bolt slide arm 282 is arranged below the lock nut 23. The upper bolt slide arm 281 interacts with the latch slide 4 via a latch deflection lever 41. The lower bolt slide arm 282 interacts with the bolt ejector 5. When the bolt slide lever 28 is rotated counterclockwise, both the bolt ejector 5 and the latch ejector 4 are actuated into the unlocked position, i.e. moved towards the face plate 22. This allows locking elements of an active sash lock (not shown) that engage in the lock housing 21 of the shoot bolt lock 2 to be displaced from the latter into an unlocked position.

[0055] The two feed slides 241, 251 are connected to each other via a reversing lever 26. As can be seen from Figure 5 As can be seen, the lower feed slide 251 is rotatably connected to the reversing lever 26 via the engagement point 254, which is designed as a pivot pin. The reversing lever 26 is designed as a two-armed reversing lever. The engagement point 254 is arranged on the first arm 261 of the reversing lever 26, and a guide pin 265 is provided on the second arm 262 of the reversing lever 26 in order to connect the reversing lever 26 to the first feed slide or the upper feed slide 241 ( Figure 6 ).

[0056] As well as from Figure 8 As can be seen, the nut lever 231 has a roller 233 at its end, which interacts with the lower retraction slide 251. When the lock nut 23 is rotated, the nut lever 231 is moved counterclockwise, whereby the roller 233 lifts the lower retraction slide 251 in order to retract the lower espagnolette rod 25.

[0057] In the Fig. 3 the deadbolt lock 2 is in accordance with Fig. 2 shown in a motor-driven unlocked position. To motor-driven unlock the espagnolette lock 2, the motor 3 is actuated so that the spindle nut 33, as shown in Fig. 3 shown, is moved upwards along the spindle 32 and thereby takes the slide plate 27 along with it. The movement takes place via the first stop surface 331 and second stop surface 332, which are each connected to the two stop pins 271, 272, which, for example, Fig. 4 are shown, are in contact and thus take the slide plate 27 with them as they move upwards along the spindle.

[0058] The locking slide lever 28 is guided with its first locking slide arm 281 or the upper locking slide arm 281 in the guide rail 273 of the slide plate 27. As a result of the movement of the slide plate 27 parallel to the face plate 22 upwards according to Figure 3, the bolt slide lever 28 is pivoted counterclockwise by the guide rail 273. Consequently, the lower or second bolt slide arm 282 pushes the bolt ejector 5 into the Figure 3 The unlocking position shown in FIG. 1 is shown in FIG. 2, in which the end of the bolt slide 5 projects beyond the face plate 22. The latch ejector 4 is also moved out of the lock housing 21 into the position shown in FIG. 1 via the reversing lever 41, which is connected to the first bolt slide arm 281. Figure 3 Move to the unlocking position shown.

[0059] In Fig. 4 The principle of unlocking the drive bolt rods when the slide plate 27 is motorized is shown. As shown in Fig. 4As can be seen, the slide plate 27 has a slide roller 274 which interacts with a control cam 263 of the reversing lever 26. The reversing lever 26 is rotatably mounted about the pivot point 264. The control cam 263 is arranged on the first arm 261 of the reversing lever 26. As a result of the movement of the slide plate 27 upwards along the arrow shown, the slide roller 274 pushes the first arm of the reversing lever 26 upwards, whereupon the lower retraction slide 251, which is connected to the first arm 261 via the engagement point 254, also moves upwards, so that the lower espagnolette rod 25 is inserted into the lock housing 21 of the espagnolette lock 2. At the same time, the second arm 262 of the reversing lever 26 moves downwards, taking with it the upper feed slide 241, which is connected to the reversing lever 26 or its second arm 262 via the guide pin 265. The connection of the lower feed slide 251 to the reversing lever 26 is described in detail in Figure 5 The connection of the upper feed slide 241 to the reversing lever 26 is shown in detail in the Figure 6 shown. During unlocking, the bell crank 26 is pivoted along the arrow shown around the pivot point 264.

[0060] When moving the deadbolt lock 2 from the locked position according to Figure 2 The spring drive 6 of the drive bolt lock 2 is loaded into an unlocked position. The spring drive 6 of the drive bolt lock 2 comprises two compression springs 61 and 62. The compression spring 61 acts on the slide plate 27. The compression spring 62 acts on the lower retraction slide 251. As can be seen by comparing the Figure 2 and 3 As can be seen, when the espagnolette lock is unlocked, the two springs 61 and 62 are compressed. In order to move the espagnolette lock 2 from the unlocked position according to Figure 3 back to the locked position according to Figure 2to guide, the spring drive 6 is released so that the espagnolette lock 2 is returned to its locked position while discharging the energy stored in the springs 61 and 62.

[0061] In addition to the Figure 3 The motorized unlocking position of the deadbolt lock 2 shown in Figure 7 the unlocking of the espagnolette lock 2 is shown in a manual manner by turning the lock nut 23. By turning the lock nut 23 counterclockwise, the nut lever 231 is also turned counterclockwise, whereby, as in Figure 8Shown enlarged, the roller 233 of the nut lever 231 carries the lower retraction slide 251 upwards. This occurs when the roller 233 is in contact with the slide stop surface 252 and, when the nut lever 231 is rotated, this is actuated upwards together with the retraction slide 251. In this case, the reversing lever 26 is pivoted, as previously with the motorized unlocking, and carries the upper retraction slide 241 downwards, which leads to the immediate retraction of the driving bolt rods 24 and 25.

[0062] When manually unlocking using the nut lever 231, it should be noted that the rotational speed of the reversing lever 26 is, at least initially, higher than with the motorized unlocking. Figure 4As can be seen from the dashed lines, the effective lever 91 between the point of application 254 and the pivot point 264 of the bell crank is greater than the effective lever 92 between the pin of the slide plate 274 and the pivot point 264 of the bell crank 26. This means that when the lock nut is rotated, i.e. during manual unlocking, the bell crank 26 disengages from the slide roller 274, in particular lifts off from it. This separates the unlocking of the espagnolette bars from the motor influence. This means that the manual unlocking cannot be influenced by the motor, so that it is always guaranteed that the espagnolette lock can be unlocked manually via the lock nut 23.

[0063] Furthermore, the nut lever 231 has a driver 232 to drive the locking slide lever 28. As in Figure 7As shown, due to the stop between the driver 232 and the bolt slide lever 28, the latter is also rotated counterclockwise when the lock nut 23 is actuated in order to move the latch ejector 4 and the bolt ejector 5 into the unlocked position. As a result of the rotation of the bolt slide lever 28, the slide plate 27 is also actuated upwards parallel to the face plate. This is shown in Figure 7 This is illustrated by the fact that the stop pins 271 and 272 are lifted from the stop surfaces 331 and 332 of the spindle drive 31, i.e., they are not operatively engaged. However, since the slide roller 274 follows the reversing lever, i.e., the reversing lever is not engaged with the slide plate, this displacement of the slide plate 27 has no disruptive influence on the mechanical or manual unlocking of the deadbolt lock.

[0064] In Figure 8It can be seen that the roller 233 of the nut lever 231 runs on a slide stop surface 252 of the lower feed slide 251.

[0065] When the motorized release of the espagnolette lock as in Fig. 3 As shown, the nut lever 231 remains stationary. The lower feed slide 251, however, is moved upwards by a motor. This lifts the slide stop surface 252 off the roller 233 of the nut lever. Starting from the position shown in Figure 7 The locking of the drive bolt lock 2 is again made possible in the same way by the support of the spring drive 6. In Figure 7 It can be seen that both springs 61 and 62 of the spring drive 6 are charged. With the support of these two springs 61, 62, the deadbolt lock 2 can be opened from the position shown in Figure 7 shown unlocking position back to the locked position according to Figure 2be spent.

[0066] In the Figure 9 For a better overview, the interaction between the bolt slide lever 28 and the latch ejector 4 is shown. According to the illustration in Figure 10 The latch ejector 4 is connected to the latch deflection lever 41 by means of a pin guided in a guide slot. The latch deflection lever 41 is designed as a two-armed pivot lever, the other arm of which is also guided via a pin in a slot of the first bolt slide arm 281. If for unlocking as in Figure 9 As indicated by the arrow, the bolt slide lever 28 is turned counterclockwise, the latch deflection lever 41 reverses the movement, which results in the latch ejector 4 being in the position shown in Figure 10 shown arrow direction out of the lock housing 21 of the espagnolette lock 2 in order to unlock a locking element, in particular a latch of an active wing lock.

[0067] It is advantageous that in the espagnolette lock 2, the motorized unlocking by means of motor 3 and slide plate 27 is separated from the mechanical unlocking by means of lock follower 23 and follower lever 231. The chain of effects for the motorized unlocking runs via the motor 3 or the motor gear 31 and the slide plate 27 to the relay lever 26. The chain of effects for the manual unlocking runs via the lock follower 23, the follower lever 231 to the lower retraction slide 251. By separating the operative engagement between the slide plate 27 and the relay lever 26 both for manual unlocking via lock follower 23 and by disengaging the operative engagement between the follower lever 231 and the lower retraction slide 251 for motorized unlocking, it is ensured that no disruptive interaction can arise between manual operation and motorized operation. This ensures that the espagnolette lock 2 can be unlocked at any time.Starting from any position, the espagnolette lock 2 can be unlocked both manually and by motor without causing any interference with the two drives.
