Description

The present invention relates to a switchable follower nut for a door lock, with a nut center part, on which driver elements are arranged rotatably about a nut axis, and on Nussmittenteil the driver elements associated Zuschalthebel are articulated, wherein the Zuschalthebel are engageable in an engaged position for engagement in the driver elements, in which of the driver elements on the Zuschalthebel a rotation transmission in the Nussemitenteil is possible, and wherein the Zuschalthebel can be brought into a release position in which a rotation transmission is interrupted by the driver elements on the Nussmittenteil.

From the WO 2005/042886 A1 is a generic switchable follower for a door lock known. The follower has a nut center part, on which driver elements are rotatably arranged about a nut axis. Furthermore, on the Nussemitenteil Zuschalthebel are arranged, which are switchable between an engaged position and a release position back and forth. Are the Zuschalthebel in the engaged position, a rotation of the driver elements, which can be introduced by a door handle, be transferred to the Nussemitenteil. Are the Zuschalthebel in the release position, so a rotation of the driver elements can not be transferred to the Nussemitenteil, so that the door handle is disabled. Regardless of the engagement position or the release position of the Zuschalthebel the rotational transmission between the driver part and the Nussemitenteil can be effected by a securing element which is designed as a cylinder screw. If the fuse element is screwed into the nut center part, regardless of the switching position of the Zuschalthebels a Transmission of the rotation of the driver element on the Nussemit part possible, and the fuse element is removed, so there is only a rotational transmission from the driver to the Nussemitenteil when the driver element associated Zuschalthebel is brought into the engaged position. Disadvantageously, the securing element only has to be completely removed from the switchable presser nut in order to achieve the effect of the associated activation lever. The Zuschalthebel can be controlled electromechanically, and through the use of the fuse element, regardless of the electromechanical switching position of the Zuschalthebels an operative connection between the driver and the Nussemitenteil be achieved regardless of which switching position the Zuschalthebef. However, the known design of the switchable follower does not allow easy switching of the nut mechanism, without not completely remove at least one fuse element to change the function of the switchable follower.

It is therefore an object of the present invention to provide a switchable follower for a door lock, which allows a simplified mechanical wiring of the nut function.

This object is achieved on the basis of a switchable follower according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous developments of the invention are specified in the dependent claims.

The invention includes the technical teaching that the Zuschalthebeln associated locking discs are provided which are rotatably received around the nut axis on the follower and which are rotatable in a first switching position in which the locking disc brings the associated Zuschalthebel in the engaged position and in a second position are rotatable, in which the locking disc brings the associated Zuschalthebel in the release position.

The invention is based on the idea to provide the wiring of the switchable follower via a locking disc, which remains permanently arranged on the switchable follower and only by a rotation between two rotational positions allows the mechanical wiring of the follower, in particular, the advantage is achieved no fuse element must be provided that must be removed from the switchable follower to change the switching state of the follower. The mechanical connection is made exclusively via the Zuschalthebel, which can be switched back and forth by the locking disc between the engaged position and the release position. The wiring of the Zuschalthebel through the locking disc only serves as additional wiring of the Zuschalthebel and the Zuschalthebel can be further connected by electromechanical switching means, unless the Zuschalthebel are not permanently held by the locking discs in the engaged position.

Advantageously, the locking discs are rotatably received on the driver elements, in particular, the locking discs can be arranged laterally adjacent to the driver discs. Due to the lateral arrangement of the locking discs, the switchable follower can continue to be designed as a compact structural unit, and the locking discs can remain permanently on the follower without having to be removed in order to change the switching position of the Zuschalthebel. The driver elements are rotatably arranged on Nussemitenteil and the locking discs are in turn rotatably received on the driver elements.

With further advantage, the locking discs have a Betätigungsanformung which can be brought into engagement with the Zuschalthebeln when the locking discs are rotated about the nut axis. The locking discs may be formed as stamped and bent metal components, and the locking discs may extend in a locking disc plane, so that the locking discs are arranged on the outside of the driver elements flat fitting. The Betätigungsanformungen may be formed as bent tabs, which extend angled out of the locking washer plane out to come into operative connection with the Zuschalthebeln. In this case, the Betätigungsanformungen in the form of the bent tabs can extend over the Zuschalthebel, and then brought into the pivoting range of Zuschalthebel when the locking discs are rotated. Is a Zuschalthebel in the engaged position, the Betätigungsanformung occurs with direct effect in contact with the Zuschalthebel. However, the Zuschalthebel is in the release position in which the Zuschalthebel from the arrangement of the follower extends out, and the locking disc is twisted with the Betätigungsanformung to the nut axis, the tab-like Betätigungsanformung comes into contact with the Zuschalthebel. The Zuschalthebel is pressed by the Betätigungsanformung in the direction of the engagement position, so that the switching position of the Zuschalthebels can be changed by simply rotating the locking disc to the nut axis. The Zuschalthebel are arranged on the Nussemit part, that the movement plane of the Zuschalthebel is located approximately in the plane of extension of the driver elements. Since the locking discs are advantageously formed as a flat stamped-bending metal components, and laterally adjacent to the driver elements, the Betätigungsanformung in the form of the bent tab over the Zuschalthebel can extend away. Consequently, it is achieved in a simple manner that the bent tab can be brought into engagement with or out of engagement with the Zuschalthebeln depending on the rotational position of the locking disc about the nut axis.

According to a further advantageous embodiment of the follower according to the invention, the Zuschalthebel can be biased by spring elements in the release position. The spring elements may be designed as spring clips, and the spring elements are arranged between the Zuschalthebeln and the articulated receiving the Zuschalthebel on Nussmittenteil so that the spring elements bias the Zuschalthebel in the release position. In this case, a portion of the spring elements so protrude from the rear of the range of movement of the Zuschalthebels that the Betätigungsanformung the locking disk then comes into contact with the spring element when the Zuschalthebel is released from the Betätigungsanformung the locking disc. If the Betätigungsanformung the locking disc by turning the locking disc about the nut axis out of engagement with the Zuschalthebel, the Betätigungsanformung engages with the spring element. The spring element is - similar to the Zuschalthebel - biased towards the nut axis, and the spring bias of the Zuschalthebels by the spring element in the release position is supported by the action of Betätigungsanformung on the spring element. As a result, the Betätigungsanformung causes either a holding arrangement of the Zuschalthebels in the engaged position, or the Betätigungsanformung enters depending on the rotational position of the locking disc on the driver with the spring element in connection, so that the spring element biases by applying the Betätigungsanformung the Zuschalthebel in the release position.

According to a further advantageous embodiment may be provided between the Nussmittenteil and the locking disc, a securing element which is arranged between Nussmittenteil and locking disc, that the rotational position of the locking disc by the securing element in the first position and / or in the second position can be locked. The first position of the locking disc can be assigned to the engagement position of the Zuschalthebels, and the second position of the locking disc can be assigned to the release position of the Zuschalthebels. Both in the first position and in the second position, the locking disc with the securing element can be rotationally connected to the Nussemitenteil so that the respective switching position of the locking disc can be changed only by re-connecting the fuse element. The fuse element remains permanently in its arrangement on the nut center part.

In the locking disc, a hole or preferably a recess may be introduced, in which the securing element can be introduced. The securing element can be designed as a screw element, as a threaded pin, as a spring-loaded cylinder pin or as another element which can be arranged holding on the nut center part or on the locking disc. Preferably, the securing element may be mounted holding the nut center part, for example, the securing element may be screwed in the shape of a profit pin in the Nussemitenteil. If the switching position of the locking disc to be changed, the securing element must be brought only temporarily out of engagement with the hole or the recess in the locking disc, and the locking disc can be rotated relative to the Nussemit part. If the securing element is designed as a threaded pin, it can for example be screwed deeper into a threaded bore in the nut center part, so as to be disengaged from the recess in the locking disc. Consequently, the lock washer can be rotated between the first position and the second position. Each of the positions of the locking disc is associated with a recess in the locking disc, and is the corresponding recess depending on the first or the second position of the locking disc brought into coincidence with the securing element, this can be brought back into engagement with the recess, for example, the Threaded pin to be unscrewed from the threaded hole in the nut center. In the same way, a screw designed as a securing element can be a piece with a screw head be unscrewed far out of the threaded hole in the Nussemitenteil so that the screw head is brought out of engagement with the recess on the locking disc.

Alternatively, the securing element may be designed as a spring-loaded cylinder pin, and if the recess is to be exchanged by turning the locking disk into which the cylinder pin engages, this need only be pressed with a tool in the direction of the nut center part in order to produce the engagement with the corresponding recess. If the spring-loaded cylinder pin is released, this snaps back into the starting position, and the cylinder pin comes into operative connection with the corresponding recess, and the locking disc is again arranged against rotation on the Nutemitenteil.

Advantageously, an adjusting ring can be arranged between the driver element and the locking disk, through which the locking disk is received on the driver element. In this case, the adjusting ring can be rotatably mounted on the driver element, wherein the locking disc, however, is rotationally received on the adjusting ring. The adjusting ring may comprise adjusting means by means of a rotational movement in the adjusting ring and thus in the locking disc can be introduced. The adjusting ring can be produced, for example, by machining production processes, in particular in order to create a slide bearing arrangement on a corresponding shoulder on the driver element. Thus, the adjusting ring is rotatably received on the shoulder of the driver element, and the locking disc may be formed as a stamped and bent metal component, in particular to produce the bent tab to form the Betätigungsanformung. The locking disc can be pressed onto the adjusting ring or arranged on this with other joining methods. With particular advantage, a positive connection can be provided between the adjusting ring and the locking disc, through which the locking disc can be arranged captively on the adjusting ring and through which the locking disc especially against rotation can be accommodated on the adjusting ring. The adjusting means provided on the adjusting ring can be formed, for example in the form of notches on the adjusting ring, in which a corresponding tool can engage to rotate the adjusting ring about the nut axis. Alternatively, the adjusting ring and the locking disc can be formed in one piece and of uniform material, in particular the locking disc can also be arranged directly on a corresponding shoulder on the driver element in order to avoid the use of the adjusting ring. The adjusting means can therefore be provided equally in the locking disc.

The present invention is further directed to a door lock with a switchable pusher as described above. In particular, the door lock may have a lock case into which the switchable handle nut can be received, wherein the lock case may have an opening with a diameter which is at least dimensioned such that at least the adjusting ring is operable through the opening and in particular through which the adjusting ring is rotatable by means of the adjusting means. In particular, the collar may have a paragraph that can be accurately inserted into the openings in the lock case. This can be done a bearing of the follower in the lock case. In particular, on both sides of the lock case, the openings may be provided so that each side of the lock case is associated with a driver element in which a door handle can be accommodated.

In the lock case can further be provided an actuation hole through which the securing element can be operated, in particular through which the securing element can be brought out of engagement with the recess in the locking disc. If the switching state of the follower is to be changed in the installed state in the lock case, the securing element can first be disengaged by the actuation hole be brought with the recess in the locking disc. Subsequently, by the adjusting means, a rotation of the adjusting ring with the locking disc to change the switching state of the follower. Subsequently, the securing element can be brought back into engagement with the recess in the locking disc to ensure the changed switching state of the follower.

In the Figures 1 and 2 are shown perspective views of an embodiment of a switchable follower 1 according to the present invention. The switchable pusher 1 is used for installation in a door lock, and the pusher 1 has a Nussemitenteil 10 which is rotatable about a nut axis 12 in the door lock. The side of the nut center part 10 driver elements 11 are arranged, and in a rotational transmission of a rotation of the driver elements 11, the nut center part 10 are also rotated about the nut axis 12. The driver elements 11 have a latch receptacle 22, in which the creations of a door handle or a door knob can be introduced. If the driver element 11 is rotated by rotation of the door handle or of the door knob about the nut axis 12, the nut center part 10 can likewise be rotated during a rotational transmission as a function of the switching state of the follower 1. In this case, an actuating arm 29, which is designed in one piece with the nut central part 10 and extends away from the nut axis 12, are actuated in order to activate the lock mechanism. Thus, for example, a case can be withdrawn into the lock case of the door lock or even a bolt can be moved by the activation of the lock mechanism.

The pusher 1 is designed as a switchable pusher 1 and has the driver elements 11 associated Zuschalthebel 13. The Zuschalthebel 13 are pivotally mounted on the Nussemitenteil 10, and can move about a lever axis 30 between an engaged position and a release position. The Zuschalthebel are engageable in the engagement position for engagement with the driver elements 11, and in the engaged position, a rotational movement of the driver 11 via the Zuschalthebel 13 in the Nussemitenteil 10 are made possible. If the Zuschalthebel 13 brought into a release position, the rotation transmission from the driver 11 is interrupted on the Nussemitenteil 10.

In the Figures 1 and 2 is in each case a Zuschalthebel 13 associated with both the front driver element and the rear driver element 11. The Zuschalthebel 13 shown on the front is in both views in an engaged position, so that a rotational movement of the front driver element 11 about the nut axis 12 on the Nussemitenteil 10 is transferable. The Zuschalthebel 13 shown on the rear side is in the release position, and a rotational movement of the driver element 11 shown behind can not on the Nut center part 10 are transmitted. Due to the release position of the Zuschalthebel 13 shown on the back, the driver geometry 28 can be seen, with the Zuschalthebel 13 can engage force-transmitting in the Mitnehmeretemente 11. As a result, split pusher door handles, which are inserted in the driver elements 11 shown on the front side, can activate the nut central part 10 and consequently the closing mechanism by an actuation. Door handles, which are accommodated in the carrier element 11 shown behind, are deactivated by the release position of the rear side Zuschalthebel 13, and actuation of the pusher elements, which are received in the rear driver elements 11 can not be transferred to the Nussemitenteil 10.

The Zuschalthebeln 13 are associated with locking discs 14 according to the present invention, which are also received around the nut axis 12 rotatably on the follower 1. Both on the front and on the rear side a locking disc 14 is shown adjacent to the respective driver element 11. The locking discs 14 are rotatable in a first position in which the locking disc 14 brings the associated Zuschalthebel 13 in the engaged position, and the locking discs 14 are rotatable to a second position in which the locking discs 14 bring the associated Zuschalthebel in the release position.

The locking disk 14 shown on the front is in the first position, so that the engagement position results for the front-side Zuschalthebel 13. The locking discs 14 have Betätigungsanformungen 15, and it can be seen that the front-side locking disc 14 with the associated Betätigungsanformung 15 acts on the front Zuschalthebel 13. By the action of the Betätigungsanformung 15 on the front Zuschalthebel 13 this is held in the engaged position, and the Betätigungsanformungen 15 are formed in the form of bent tabs extending over the back of the Zuschalthebel 13 extend. The locking discs 14 shown on the back are in the second position, so that the release position results for the Zuschalthebel 13 shown at the back. It can be seen that the Betätigungsanformung 15 of the rear locking disc 14 is not in operative connection with the Zuschalthebel 13.

The Zuschalthebeln 13 spring elements 27 are assigned, are biased by the Zuschalthebel 13 in the release position, especially when the locking plates 14 are located with the Betätigungsanformungen 15 in the second position, as shown by the rear lock plate 14 shown. In the second position of the locking discs 14, the Betätigungsanformungen 15 act on the spring elements 27, and push them in the direction of the nut axis 12. As a result, the Zuschalthebel 13 are transferred to the release position. As a result, when the operating protrusions 15 are in engagement with the engaging levers 13 according to the front side view, the spring elements 27 slightly protrude from the follower 1 according to the front side view. As a result, it is achieved that an unnecessary bias of the spring elements 27 can be omitted when the Zuschalthebel 13 are brought into the engaged position by the locking discs are rotated to the first position. Thereby, the rotation of the locking discs 13 between the first and the second position can be facilitated.

Between the nut central portion 10 and the locking disc 14, a Sicherungselemenf 16 is provided and is arranged so that the rotational position of the locking disc 14 by the securing element 16 in the first position and / or in the second position can be locked. The securing element 16 is shown by way of example as a screw element and is screwed into the nut center part 10. In the locking disc 14, a recess 17 is introduced, in which the securing element 16 engages. The lock washers 14 have two recesses 17, and each of the recess 17 is associated with a switching position of the locking disc 14. In the Figures 1 and 2 the securing elements 16 are respectively inserted into the recesses 17, which lock the locking disc 14 in the first position, which corresponds to the engagement position of the Zuschalthebels 13 shown on the front Would the fuse element 16 are introduced in the free recess 17, the locking disc 14 would be in the second Locked position corresponding to the release position of the Zuschalthebel 13.

The securing elements 16 are arranged on the nut center part 10 in such a way that disassembly of the securing element 16 for use from one side of the nut center part 10 on the other side of the nut center part 10 is prevented.

If the switching states of the locking discs 14 are to be changed, then the securing element 16 can be screwed a little way into the nut central part 10, and the locking disc 14 can be rotated, and indeed so far until the freely shown recess 17 comes into coincidence with the securing element 16 , Subsequently, the fuse element 16 can be unscrewed again. The locking discs 14 are secured against rotation on a collar 18, wherein the adjusting ring 18 is in turn rotatably mounted on the driver element 11. This results in an advantageously implemented rotatable arrangement of the locking discs 14 on the driver elements 11th

FIG. 3 shows a side view of the switchable follower 1 with a sectional plane AA, the in FIG. 4 is shown. The nut central part 10 forms the main body of the switchable presser foot 1, and in the cross-sectional view AA it can be seen that the driver elements 11 are rotatably received on the nut central part 10. Between the driver elements 11, a separating element 31 is shown, is prevented by the fact that the shaft of a door handle or a rotary knob too far into a pawl receptacle 22 of a driver element 11 inside is introduced, and the shaft can not engage in engagement with the pawl receptacle 22 of the opposing driver element 11.

The locking discs 14, which are formed as stamped and bent metal components, are also rotatably received on adjusting rings 18 about the nut axis 12. The collars 18 sit on a receiving collar 32 which is integrally formed on the respective driver elements 11. In the representation A-A can be seen that the locking discs 14 on the outside rest flat against the driver elements 11. Also shown are Zuschalthebel 13, wherein in the view A-A of the left Zuschalthebel 13 is in the engaged position and the right Zuschalthebel 13 in the release position.

Adjusting means 19 in the form of indentations are laterally shown on the adjusting ring 18, and the adjustment means 19 can be used to rotate the adjusting ring 18 and consequently the locking disk 14 about the nut axis 12 in order to alternately bring the recesses 17 into engagement with the securing element 16.

FIG. 5 shows a side view of a door lock 5 with a lock case 20, in which a switchable pusher 1 is inserted. The lock case 20 has an opening 21 which is dimensioned such that through the opening 21 of the adjusting ring 18 is operable from the outside. In particular, the adjusting means 19 can be reached on the adjusting ring 18 with a tool, so that the adjusting ring 18 and consequently the locking discs 14 can be rotated about the nut axis 12. The latch receptacle 22 serves to receive a door handle or a door knob, and on the underside a lock cylinder receptacle 24 is further shown, which is inserted in the lock case 20. The door lock 5 has a latch 26, which can be activated via the switchable follower 1, wherein furthermore a lock bolt 25 is shown, preferably via a Lock cylinder is activated, which can be received in the lock cylinder receptacle 24.

If the switching position of the switchable follower 1 is to be changed, the securing element 16 can first be brought out of engagement with the recess 17 through the actuating hole 23. Subsequently, an adjustment of the adjusting ring 18 by means of the adjusting means 19 can be effected through the opening 21. Subsequently, the securing element 16 can again be brought into engagement with a recess 17 through the actuating hole 23.

The actuation hole 23 is designed such that it has a smaller diameter than the outer diameter of the securing element 16, whereby the securing element 16 is captively caught in the housing of the door lock 5, if the securing element 16 should be released from the nut center part 10.

After setting the switchable follower 1, it is conceivable to close the actuation hole 23 with an object, this object either being removable again or the actuation hole 23 can be designed to be finally closable.

The invention is not limited in its execution to the above-mentioned preferred embodiment. Rather, a number of variants is conceivable, which makes use of the illustrated solution even with fundamentally different types of use. Any features and / or advantages resulting from the claims, the description or the drawings, including constructive details or spatial arrangements, can be essential to the invention, both individually and in the most diverse combinations. In particular, the switchable follower 1 may also be merely a switchable driver element 11 with an associated Zuschalthebel 13, and the door lock 5 may be formed only for receiving a door handle. Furthermore, the securing element 16 may alternatively be accommodated in the locking nut 14 or in the adjusting ring 18 for receiving in the nut center part 10. In particular, the adjusting ring 18 and the locking disc 14 may be integrally formed with each other, or the locking disc 14 is disposed directly rotatable on the driver element 11.
