Description

The invention relates to a locking bar for a mortise lock. The locking bar is suitable for being arranged in a linear guide of a door leaf and being displaceable in a displacement direction. The locking bar includes a fastening section. The fastening section is used for fastening to a rod connection of the mortise lock. The locking bar also includes an end portion. The end section faces away from the fastening section. The invention also relates to a mortise lock with a locking bar according to the invention and a door leaf with a mortise lock according to the invention.

Generic locking bars are used according to the prior art in order to fix a door leaf in the vertical direction. Here, the locking bars engage in the floor and / or in a ceiling or in a door frame, the locking bars being in an extended position. The mortise lock is inserted into the door leaf and fastened there. The locking bars run in a guide inside the door leaf. Because the guide runs linearly upwards or downwards in the door leaf of the fully assembled door, the guides are very long. Only a small offset between a lock housing of the mortise lock and the locking bar can therefore lead to the locking bar jamming in the guide. The jamming prevents the locking bar from moving into the extended position or into a retracted position. This can endanger security, especially with fire protection doors.

It is therefore the object of the invention to provide a locking bar and a mortise lock in which a movement of the locking bar within the guide is better guaranteed.

The problem is solved by the features of the independent claim. The dependent claims have advantageous embodiments of Invention to the subject. Features and details that are described in connection with the locking bar according to the invention also apply to the mortise lock according to the invention. Features and details that are described in connection with the mortise lock according to the invention also apply to the door leaf according to the invention.

It is provided that the locking bar comprises at least one articulated connecting device. The connecting device is arranged between the fastening section and the end section. The end section can be deflected transversely to the direction of displacement by the connecting device.

Because the locking bar has a hinge-like connecting device between the fastening section and the end section, the fastening section can be fixable in the rod connection. The end section of the locking bar, however, remains flexible to a certain extent due to the connecting device and can be deflected transversely to the direction of displacement. If a lock housing of the mortise lock and the guide are provided with an undesired offset due to manufacturing tolerances, the connecting device compensates for the offset in such a way that the locking bar does not jam in the guide. This increases the security that the locking bar can move into a retracted position and into an extended position. The end section is pivotable in particular on the connecting device.

The locking bar is preferably designed to be unbent. The locking bar is used in particular to be moved in a straight guide of a door leaf. In a mounted door, the locking bar is used in particular to be moved vertically. The guide is preferably located inside the door leaf.

The locking bar can assume a retracted position. In the retracted position, the locking bar is out of engagement with one Door frame, a floor or a ceiling. The locking bar can assume an extended position. In the extended position, the latch bar engages a door frame, floor, or ceiling.

The locking bar can be moved from the retracted position to the extended position in the direction of displacement. The locking bar can be moved from the extended position to the retracted position against the direction of displacement.

The mortise lock is used to be inserted into a door leaf. The mortise lock preferably has a faceplate in order to be fastened to the door leaf.

The mortise lock has a lock housing.

The fastening section preferably forms one end of the locking bar. The end section preferably forms the opposite end of the locking rod.

The locking bar is designed in particular as an upper locking bar. In the assembled door, the locking bar is thus arranged above the lock case.

In particular, the fastening section comprises a length which enables the locking rod to overlap the rod connection to different degrees. This allows the length of the locking bar to be adjusted, measured from the bar connection. In particular, the locking rod can be received in the rod connection to different extents. The locking bar is in particular firmly connected to the bar connection. In particular, the locking bar is connected to the bar connection in a tension-proof and / or pressure-proof and / or non-rotatable manner.

According to the invention it is provided that the locking rod comprises a first locking rod part and a second locking rod part. The connecting device connects the first and the second locking rod part in an articulated manner.

The connecting device comprises an opening of the first locking rod part and a rod-shaped engagement element of the second locking rod part. The opening is open in or against the direction of displacement. The opening can be open to the lock housing or in the opposite direction. The engagement element of the second locking rod part engages in the opening in such a way that the first and second locking rod parts can be tilted relative to one another. The articulation-like effect of the connecting device is achieved through the tiltability. The first and second locking rod parts can be deflected relative to one another by means of the connecting device.

An elongated engaging element is understood as a rod-shaped engaging element. The engagement element forms, in particular, one end of the second locking element part. In particular, the opening forms one end of the first locking rod part.

The opening can comprise a wall.

The engagement element can comprise at least one side surface and a top surface. The wall corresponds to the side surface. In other words, the wall is adjacent to the side surface. The side surface can in particular be designed as a jacket surface. The wall can surround the lateral surface.

The engaging element can be made uniformly thick or narrowing.

It may be that the opening and / or the engagement element are cylindrical. Alternatively, the engagement element can be conical or frustoconical. The engagement element can comprise at least one cylindrical section. The engaging element may comprise a plurality of cylindrical or frustoconical sections.

A diameter of the engagement element is preferably smaller than the corresponding diameter of the opening, so that there is play between the There is engagement element and the wall of the opening. The tiltability can hereby be achieved. Corresponding here is understood to mean an arrangement at the same height as the locking bar.

The top surface of the engagement element is preferably not in contact with the wall of the opening. In particular, the side surface of the engagement element rests against the wall of the opening.

A deflection angle of the end section is defined as an angle between the locking bar, in particular the end section, in the deflected state and the locking bar, in particular the end section, in the non-deflected state.

It can be provided that the deflection angle of the end section is limited by the engagement element resting in the opening. The deflection of the end section is limited by the engagement of the engaging element on the wall. The deflection, in particular the deflection angle, of the end section is particularly preferably limited by a side surface, in particular the lateral surface, resting against the wall.

It is preferably provided that end points to which the end section can be maximally deflected by the connecting device lie on a circle. This makes it possible for the locking rod to be fastened in different orientations in the rod connection without the ability to compensate for an offset between the lock housing and the guide being impaired. It may be that the opening and / or the engaging element has a circular diameter in order to achieve that the end points lie on a circle. In particular, the wall and / or the side surface can have a circular diameter at a contact point at which the side surface is in contact with the wall.

It can be provided that the maximum deflection angle of the end section is between 0.5 ° and 7 °, preferably between 1 ° and 5 °, particularly preferably between 2 ° and 3 °.

It is preferably provided that the connecting device has a recess. The recess is limited in particular in and against the direction of displacement. Thus, the recess comprises walls in and against the direction of displacement as a delimitation of the recess. One of the locking rod parts comprises the recess, while the other of the locking rod parts engages in the recess. The wall of the opening can thus have the recess. The engagement element engages in the recess. Alternatively or additionally, the engagement element can have in the recess and the wall of the opening can engage in the recess.

The locking rod part engaging in the recess preferably rests against the delimitation of the recess in the direction of displacement. As a result, a pressure can be transmitted from the rod connection to the end section, so that the locking rod can be moved into the extended position. The locking rod part engaging in the recess can rest against the boundary against the direction of displacement. In this way, a pull can be transmitted from the rod connection to the end section, so that the locking rod can be moved into the retracted position. The engagement in the recess ensures that the locking bar is pressure and tensile resistant. Particularly preferably, at the same time, the locking rod part engaging in the recess rests against the delimitation of the recess both in the direction of displacement and against the direction of displacement.

The engagement element particularly preferably rests in the opening in the recess, so that the deflection of the end section is limited by the contact in the recess. The engagement element rests in the opening in the recess, so that the deflection of the first locking rod part relative to the second locking rod part is limited by the abutment in the recess. The engagement element preferably rests in the recess in such a way that the contact takes place in the direction of displacement and / or against the direction of displacement. Particularly preferably, the engagement element rests in the recess in such a way that the contact takes place in the direction of displacement and at the same time against the direction of displacement. The engaging element can comprise a plurality of contact points against which the engaging element rests in the recess. So can it Engaging element bear against the recess at a first contact point in the direction of displacement and bear against the direction of displacement at a second contact point.

The recess can be designed as a slot. The recess can be designed as a groove. The recess can be designed as a thread. The recess can be designed as an internal thread of the opening. The recess can be designed as an external thread of the engagement element.

It is preferably provided that the opening comprises an internal thread into which the engagement element engages with an external thread. The recess can thus be designed as the internal thread. The at least one contact point, preferably the multiple contact points, of the engagement element are located on the external thread.

Because there is play between the internal thread and the external thread, the end section can be deflected with respect to the fastening section. Because the external thread rests against the internal thread in and / or against the displacement direction in the deflected position of the end section, compressive and / or tensile strength can be achieved. Thus, at a contact point of the external thread, the external thread can rest against the internal thread in the displacement direction. At another contact point of the external thread, the external thread can rest against the internal thread against the direction of displacement. At the same time, the external thread preferably rests against the internal thread in and against the direction of displacement.

It is conceivable that the internal thread and the external thread can be separated by between one and eight revolutions, preferably by between two and six revolutions, particularly preferably between three and five revolutions. This achieves a particularly good balance between deflectability and compressive and tensile strength.

In particular, it is provided that the recess, in particular the internal thread, is that end of the locking rod part formed with the recess which is the locking rod part engaging in the recess is facing, forms. The opening can comprise several sections. The portion facing the engaging element may include the recess.

It is preferably provided that the fastening section comprises a thread. The fastening section comprises in particular an external thread. The fastening section can be fastened to the rod connection by means of the thread. Thus, the locking rod is preferably attached to the rod connection by a rotary movement. For this purpose, the rod connection can comprise an internal thread.

It may be that the connecting device comprises a pin arranged transversely to the direction of displacement and a passage. The passage corresponds in particular to the pin. Here, one of the locking rod parts comprises the pin and the other of the locking rod parts the passage. The pin engages in the passage. In particular, when the pin rests on the passage, the first and second locking rod parts can be rotated together. In particular, the pin rests on the passage transversely to the direction of displacement. This makes it possible to transmit a torque from the passage to the pin or from the pin to the passage.

The engagement element may include the pin. The opening can be formed with the passage. In particular, the passage leads through the wall of the opening.

The connecting device preferably comprises both the recess and the passage. The recess and the passage are preferably arranged at a distance from one another. With the recess, the connecting device comprises a first form-locking device, which ensures compressive and / or tensile strength. With the passage, the connecting device comprises a second form-locking device, by means of which a certain torsional strength is achieved.

The tensile and / or compressive forces are preferably transmitted via a thread, in particular via the external thread of the engagement element, which is shown in FIG the internal thread of the opening engages. Particularly preferably, there are no tensile and / or compressive forces on the pin. This brings increased security against tearing off the articulated connection. Tearing it off would make the door unsafe.

In particular, a play between the pin and the passage can be formed in such a way that only the contact of the engaging element on the wall of the opening limits the deflection and / or the deflection angle of the end section. Thus, in particular, the play between the pin and the passage is greater than between the recess and the engagement element. In particular, the play between the pin and the passage is greater than between the external thread and the internal thread. The deflection of the end section is thus limited by the recess and not by the pin resting against the passage. This ensures the circular position of the end points. It is thus conceivable that initially a slight rotation of the one locking rod part against the other locking rod part takes place before a torsional strength is achieved by the contact of the pin on the passage. For example, the rotation is less than 150 °, particularly preferably less than 90 °, particularly preferably less than 50 °, before the pin rests on the passage.

It can be provided that the pin is arranged deeper than the recess in the opening. In particular, the engagement element can have a smaller diameter at the level of the pin than at the level of the recess. The smaller diameter prevents the engagement element from resting on the wall at the level of the pin. The engagement element and the opening can have a greater play to one another at the level of the pin than at the level of the recess. Thus, the engagement of the engaging element in the recess limits the deflection of the end section.

The distance between the connecting device and the fastening section is preferably smaller than the distance between the connecting device and the end section. For example, the distance between the connecting device and the end section is more than twice, preferably more than four times, particularly preferably more than eight times the distance between the connecting device and the fastening section. This makes it possible to achieve a large deflection of the end section through a small deflection angle.

The object of the invention is also achieved by a mortise lock with a locking bar according to the invention. The locking bar can be designed as described.

The mortise lock preferably has an actuating device by means of which the locking bar can be moved from the extended to the retracted position. The actuating device can be designed as a nut, which with a handle, for. B. a panic bar or a door handle can be connected. The actuating device is preferably arranged in the lock housing.

The mortise lock can be an electrical actuator, e.g. B. comprise a motor, which moves the locking bar from the extended position to the retracted position. The electrical actuator is preferably arranged in the lock housing.

The mortise lock can be designed as a door lock for an active leaf door. In this case, the mortise lock can comprise at least one locking element, in particular a latch and / or a bolt, which can be extended into a strike plate. The at least one locking element is preferably mounted in the lock housing. The at least one locking element can preferably be withdrawn into the lock housing via the actuating device and / or the actuator.

The mortise lock can be designed as a door lock for a fixed leaf door. In this case, the mortise lock can comprise an actuator for a locking element, in particular for a latch and / or a bolt, in order to push the locking element out of the door lock. The actuator is preferably arranged in the lock housing. The actuator is preferably movable in the lock housing via the actuation device and / or the actuator.

The rod connection is preferably arranged at least partially in the lock housing. The rod connection is preferably mounted in or on the lock housing. For this purpose, the lock housing can comprise at least one opening in which the rod connection is guided. The locking bar is preferably moved by the actuating device and / or the actuator via the bar connection.

The mortise lock preferably comprises at least one tool opening in the lock housing and / or in the faceplate. The tool opening is used to attach the rod connector and the locking rod to one another. The tool opening is used to fasten the rod connection and the locking rod to one another when the lock housing is already arranged in the door leaf.

The rod connection can comprise a clamping device with which the locking rod is fixed in the rod connection. This enables the length of the locking bar to be precisely adjusted. In particular, the clamping device prevents the locking bar from becoming detached from the bar connection when the lock is in operation. The clamping device can in particular be provided in addition to the screw connection between the rod connection and the locking rod. The clamp connection is preferably arranged in the lock housing.

The clamping connection can be actuated through the tool opening. For example, the clamping device can comprise a screw. The screw can be turned through the tool opening. With the mortise lock that is already inserted in the door, the tool opening enables the locking bar to be fixed to the bar connection.

The invention is also achieved by a door leaf with a mortise lock according to the invention. The door leaf includes a pocket for receiving the lock housing. The door leaf includes a guide for guiding the locking bar according to the invention. The guide is preferably located inside the door leaf.

The invention will now be described in more detail using an exemplary embodiment. Show:

In Figure 1 a mortise lock 1 according to the invention is shown. The mortise lock 1 according to the invention comprises a lock housing 3 and a faceplate 4. The faceplate 4 is used to fasten the mortise lock 1 to a door leaf (not shown) of a door. Here, the mortise lock 1 is in a pocket of the door leaf.

The mortise lock 1 comprises an upper locking bar 10 and a lower locking bar 8. The locking bars 8, 10 are shown in FIG Figure 1 not shown in full length. The upper and lower locking rods 8, 10 serve to be moved in a vertical guide of the already assembled door leaf. The guide is located inside the door leaf. Here, the locking bars 8, 10 between a retracted position and a extended position. In the retracted position, the locking bars 8, 10 are out of engagement with a floor, a door frame and / or a ceiling. In the extended position, the locking bars 8, 10 are in engagement with the floor, the door frame and / or a ceiling. The movements of the upper and lower locking rods 8, 10 take place against each other.

The movement of the upper locking bar 10 from the retracted position to the extended position takes place in a displacement direction 100. The movement of the upper locking bar 10 from the extended position into the retracted position takes place against the displacement direction 100.

The mortise lock 1 comprises rod connections 2. The rod connections 2 are at least partially arranged in the lock housing 3. The rod connections are guided on the lock housing 3. The locking rods 8, 10 are fastened to the rod connections 2. The rod connections 2 are operatively connected to one another.

The rod connections 2 are in operative connection with a nut 5 as an actuating device. The nut 5 is with a handle, for. B. a panic bar or a door handle, connectable. The rod connections 2 are in operative connection with an electric motor 6 as an actuator. If the nut 5 and / or the actuator 6 is actuated, the rod connections 2 and thus the locking rods 8, 10 move. This allows the locking rods 8, 10 to be moved from the extended position to the respective retracted position.

The upper locking rod 10 comprises a spring 11. The spring 11 is tensioned in the retracted position of the upper locking rod 10. By means of the spring 11, the upper locking rod 10 and the lower locking rod 8, which is operatively connected to the upper locking rod 10, can be moved into the respective extended position.

The mortise lock 1 in Figure 1 is designed as a lock for a fixed leaf door. The mortise lock 1 therefore comprises an actuator 7 to release a bolt, not shown, which can engage in the mortise lock 1 To be able to push out the lock housing 3. The bolt belongs to an active leaf lock.

The pocket of the door leaf for the lock housing 3 and the guide of the door leaf for the locking bar 10 can be offset from one another due to error tolerances.

Figure 2 shows the upper locking bar 10 from Figure 1 in full length. The locking bar 10 comprises a fastening section 12. The fastening section 12 comprises an external thread (not shown) with which the fastening section can be screwed into an internal thread of the rod connection 2. The fastening section 12 is located at one end of the locking rod 10. The other end of the locking rod 10 is designated as the end section 13.

In order to avoid jamming of the locking bar 10 in the guide due to the error tolerances, the locking bar 10 comprises an articulated connecting device 20 (see Sect. Fig. 3 ). As in Figure 3 As shown, the connecting device 20 is located within the spring 11 and a spring support 14 via which the spring 11 is supported on the lock housing 3. By means of the joint-like connecting device 20, the end section 13 can be deflected transversely to the displacement direction 100. This avoids jamming of the locking bar 10 in the guide.

The locking bar 10 comprises a first locking bar part 15 and a second locking bar part 16, as in FIG Figure 3 shown. In addition, the locking bar 10 comprises a third locking bar part 17 (see FIG. Fig. 2 ), which is firmly and immovably connected to the first locking rod part 15. The third locking rod part 17 can thus be pressed with the first locking rod part 15. The third locking rod part 17 also forms a system for the spring 11. The first locking rod part 15 is located under the spring 11. The second locking rod part 16 is partially located under the spring support 14. The second locking rod part 16 includes the fastening section 12. Here, the external thread of the Fastening section 12 not shown.

The connecting device 20 connects the first and second locking rod parts 15, 16 to one another in an articulated manner.

Figure 4 shows the locking rod parts 15, 16 in a connected state. Figure 5 shows the locking rod parts 15, 16 in an exploded view. Here, the first locking rod part 15 is only partially shown. Fig. 6 shows the first locking rod part 15 in a slightly perspective top view in the displacement direction 100. Figure 7 shows a sectional illustration through the connecting device 20.

As in the Figures 4 to 6 As shown, the first locking rod part 15 comprises an opening 21. The second locking rod part 16 comprises an engaging element 22. The opening 21 is located at the end of the first locking rod part 15 which faces the second locking rod part 16. The opening 21 is open in the displacement direction 100. The engagement element 22 of the second locking rod part 16 forms the end of the second locking rod part 16 which faces the first locking rod part 15.

The engagement element 22 engages in the opening 21. Here there is play between a wall 28 of the opening 21 and the engagement element 22 such that the first locking rod part 15 and thus the end section 13 can be deflected relative to the second locking rod part 16. The first locking rod part 15 and the second locking rod part 16 can be tilted relative to one another.

The opening 21 and the engaging element 22 thus together form the connecting device 20. As a result of the engaging element 22 resting against the wall 28 of the opening 21, the maximum deflection of the end section 13 is limited.

The engagement element 22 comprises a first section 23 and a second section 24. The first and second sections 23, 24 are each cylindrical. The first section 23, which faces away from the opening 21, has a larger diameter than the second section 24.

Correspondingly, the opening 21 comprises a first section 29. The first section 29 of the opening 21 is at the same height in the direction of displacement 100 as the first section 23 of the engaging element 22. The opening 21 comprises a second section 30. The second section 30 of the opening 21 is at the same height in the direction of displacement 100 as the second section 24 of the engagement element 22.

The first section 23 of the engagement element 22 is designed as an external thread 23. The first section 29 of the opening 21 is designed as an internal thread 29. The internal thread 29 and the external thread 23 overlap, for example, in such a way that the internal thread 29 and the external thread 23 can be separated in approximately 3 to 5 revolutions of the first locking rod part 15.

The internal thread 29 serves as a recess. The internal thread 29 limits movement of the second locking rod part 16 relative to the first locking rod part 15 in the direction of displacement 100 and against the direction of displacement 100 because the external thread 23 engages in the internal thread 29. For this purpose, the internal thread 29 comprises flanks. The external thread 23 engages with the flanks of the external thread 23 in the internal thread 29.

There is play between the external thread 23 and the internal thread 29. This enables the end section 13 to be deflected. The maximum deflection of the end section 13 is limited by the contact between the external thread 23 and the internal thread 29.

Because the maximum deflection of the end section 13 depends on the rotationally symmetrical thread 23, 29, end points to which the end section 13 can be maximally deflected lie on a circle. The end section is thus equally deflectable in all directions transverse to the displacement direction 100.

By limiting the mobility of the locking rod parts 15, 16 by the flanks of the internal thread, the connecting device 20 is resistant to pressure and tension.

A deflection angle indicates the deflection of the end section 13 relative to the undeflected position 200 of the locking bar 10. The maximum deflection angle is 2-3 °.

The first section 29 of the opening 21 is located at the end of the opening 21 which faces the second locking rod section 16. The first section 29 is thus located at the “beginning” of the opening 21.

The second section 30 of the opening 21 and the second section 24 of the engaging element 22 have a significantly greater play to one another than the first section 29 of the opening 21 and the first section 23 of the engaging element 22. This enables the second sections 24, 30 that the first Sections 23, 29 limit the deflection of the end section 13. A top surface 30 of the engagement element 22 does not lie against the wall 28 of the opening 21. The top surface 30 remains at a distance from the wall 28 even with maximum deflection of the end section 13.

The second section 24 includes a hole 26 in which a pin 25 is attached. In particular, the pin 25 is pressed into the hole 26. The engagement element 22, in particular the second section 24, thus comprises the pin 25.

The pin 25 passes through opposite passages 27 of the first locking rod part 15, in particular of the second section 30. Of the passages 27 is in the Figures 4, 5 and 7th only one passage 27 is shown in each case. The passages 27 are opposite one another. As a result, the passages 27 enclose a central angle of 180 °.

The passages 27 have a larger diameter than the pin 25. The diameter of the passages 27 is selected in such a way that a contact of the pin 25 on the passage 27 does not limit the deflection of the end section 13. Rather, there is play between the internal thread 29 and the external thread 23 less, so that only the contact of the external thread 23 on the internal thread 29 limits the deflection of the locking bar 10.

The pin 25 and the passages 27 serve that the second locking rod part 16 can be rotated with the first locking rod part 15. In this way, screwing in or screwing out of the rod connection 2 is possible. Due to the play between the pin 25 and the passages 27, the first locking rod part 15 is initially rotated without taking the second locking rod part 16 with it. If the pin 25 comes to rest on the passages 27 transversely to the displacement direction 100, the second locking rod part 16 is rotated along with it.

The articulated connecting device 20 according to the invention thus makes it possible to create a connection between two locking rod parts 15, 16 in which one locking rod part 15 can be deflected relative to the other locking rod part 16. Nevertheless, the connection is pressure-resistant and tensile-proof and, to a certain extent, also torsion-proof.

The connecting device 20 is provided near the attachment portion 12. In this way, due to the length of the locking bar 10, a large deflection can be achieved. Thus, a distance between the connecting device 20, measured at the pin 25, to a tip of the end section 13 can be more than eight times the distance between the connecting device 20 and the fastening section 12.

The fastening section 12 is fixed to the rod connection 2 by a clamping device (not shown). The clamping device is located in the lock housing 3. For fixing purposes, the faceplate 4 and the lock housing 3 have a tool opening (not shown) through which a tool can be inserted. The tool can turn a screw of the clamping device. Thus, the fastening section 12 and the rod connection 2 are immovably fastened to one another.
