A clutch carrier is provided, where the coupling carrier has an actuating extension (17), to which the closing element (21) is connected in the latch withdrawal position during a rotation of the lock cylinder in open direction.

Description

The invention relates to a lock, in particular mortise lock with a lockable by turning a closing member of a lock cylinder inserted into the lock and with a latch by a handle operation from a leading position in a release position retractable traps, with a first pusher half, permanently with the case is coupled with movement and with a second pusher half, which is only coupled in movement in the locked back latch position with the case, including a coupling transformer is provided, which occurs in the Vorschließbewegung from an operative position to a non-operative position.

The EP 0 204 944 describes a mortise lock in which by turning a closing member of a plugged into a profile opening of a lock box lock a bolt can be closed and then closed again. In the locked position, a trap can be withdrawn by the operation of a pusher. The lock has a two-part handle nut, so that the lock can be equipped with an internal handle and an external handle. The inner pusher is permanently coupled with the latch tail of the latch. For this purpose, an arm of the pusher nut permanently coupled to the inner half of the nut engages a latch tail in order to retract the latch against the restoring force of a latch spring. The pusher nut can also be coupled to the outer half of the nut, so that a latch retraction is also possible by operating the outer pusher.

The castle is a panic lock. When the latch is locked, the outside handle will not be able to retract the latch. The outer half of the nut is not motion coupled to the tail-tail. A related coupling element is brought out of operative position. Is at operated a pre-closed locking position of the inner handle, the bolt is withdrawn from a latch retraction. This is accompanied by a previous lifting a tumbler. In the closed position, the coupling element is brought into effect, so that a case operation can take place both from the inside and from the outside.

The DE 10 2005 039 287 B4 describes an anti-panic lock, in which the pre-locked bar can also be withdrawn by pressing a pusher nut. In order to operate this lock from the outside, an exchange function is provided with which the case can be withdrawn by key operation.

The DE 41 43 292 C2 describes a lock in which by means of a transfer pivot lever of the Vorschlussweg the bolt is increased. The transfer pivot lever sits in the rear area of the lock and connects two superimposed sliders together.

Based on the above-mentioned prior art, the present invention seeks to further develop the castle benefits of use.

The object is achieved by the invention specified in the claims.

First and foremost, it is proposed that the coupling transformer has an actuating extension projecting into the circular arc movement path of the closing element in the non-operative position. At this actuation extension, the closing member engages in the locking retraction position when the lock cylinder is rotated in the opening direction. During this rotation, the coupling transformer is moved to its operative position in which he couples the two halves nut together. The clutch operation corresponds to the movement ago a change operation in a lock according to the state of the technique. The actuating extension is preferably elastically evasive associated with the coupling slide formed as a coupling slider, that the actuating extension can dodge elastically in a lying in the path of movement of the actuating extension closing member at a caused by a rotation of the first pusher latch locking retraction and a concomitant displacement of the coupling slide. This measure is particularly advantageous if the lock according to the invention is designed as a panic lock, in which the bolt is closed by pressing the internal pusher along with the Fallenrückzug. If the lock cylinder is a knob cylinder or if a key is inserted in the lock cylinder, the lock member has an undefined rotational position. For the panic function to be properly exercised, the closing element must not interfere with neither the bolt nor the coupling slide in its movement. The elastic evasion of the actuating extension thus ensures that the coupling slide can take its final position when bolt retraction. If the closing member lies in the movement path of the actuating extension, the actuating extension deviates. The actuating extension is preferably acted upon by a spring element. This spring element may be a leg spring. The actuating extension is preferably located at a lower end of the coupling slide. The coupling with which the two nut halves can be coupled in the operative position of the coupling slide is formed by a coupling pawl. This coupling pawl can be hinged to a Nussarm and can be acted upon by a spring in a decoupled position. The coupling pawl forms a sliding flank, on which a coupling flank of the coupling slide can engage in order to bring the coupling pawl into its operative position. In this a coupling shoulder is supported on a coupling flank. The coupling slide can form a niche, which forms two, substantially V-shaped converging niche walls, each acting as control cams. About a first cam of the Coupling slides are brought in the conclusion of the bolt from its operative position. With the second control cam, the coupling slide can be displaced at the bolt back. To hold the coupling slide in its operative position, a catch is provided. This can be formed by a housing-fixed locking pin, which enters a latching niche of the coupling slide.

The invention also relates to a lock, in particular mortise lock with a lockable by turning a closing member of a lock cylinder inserted into the lock and back and with a retractable by pusher operation of a default position in a release position case, wherein the locked lock in the way of a panic function also can be withdrawn with a latch retracting arm which can be pivoted in the event of a pusher operation and acts on the bolt, and in which case the locking member acts on a projection of the bolt during bolt feed.

Such a lock is known from the aforementioned prior art.

To achieve the object mentioned above, it is provided that the projection is associated with a slide, which is displaced in the panic function of a lifting mechanism. The displacement takes place in the direction away from the lock cylinder. It is optimal if the projection is located after the displacement outside the circular arc movement path of the closing member. According to this embodiment, the actuation safety of a panic lock is increased. In the case of a panic lock, the latch dead-end occurs in the event of a panic without the lock cylinder being actuated. If, in a lock according to the prior art, the closing member of the lock cylinder in an unfavorable position, so the attack projection of the bolt can abut against the closing member. The retractability of the bolt can be blocked. But by the projection one Associated with slide, which is outside the circular arc movement path of the closing member in the panic function, a collision of the projection is prevented with the closing member. In a further development of the invention it is provided that the slider is displaced against the force of a spring from the lifting mechanism. The spring is tensioned when the inner handle of the lock is actuated. This actuation sets in motion the displacement of a lifting mechanism which, for example, engages under a projection of the slide in order to displace the slide relative to the latch. In the raised position of the slider, a locking pin enters into a latching niche to hold the slider in the safety position, in which the projection is outside the circular arc movement path of the closing member. The rest can be coupled with a trigger. This release causes the slider to remain in its safety position until the latch is fully closed. Only then the trigger is actuated and released the latch so that the spring can push the slider back to the starting position. The shutter preferably cooperates with the rear wall of the lock. This forms a stop surface against which the trigger occurs. The lifting mechanism may have a crank pin which lies at the end of a lifting arm. The lifting arm may be formed by a pivot lever which is rotatable about a housing-fixed axis. This lever is connected via a tension member with a second Nussarm. When the nut is turned, the lifting arm pivots. The second Nussarm may also have a drive cam, which may be formed by a drive pin. This attacks delayed movement after lifting the slider on the bolt retraction arm. The bolt retraction thus occurs only when the slide has been moved to its rest position. Along with the lifting of the slide and a guard is raised, which holds the latch in the pre-closed position. For this purpose, the guard may be coupled to the slider.

The invention relates to a lock, in particular mortise lock with a by turning a closing member of a lock cylinder inserted into the lock and retractable, a projection for attacking the closing member having latch, wherein to increase the latch closure pivotable about a housing pivot axis, attacking the bolt Feed lever is provided.

Such a lock is known from the aforementioned prior art.

To solve the above-mentioned problem, it is proposed that the feed lever is mounted in the lock so that, after a first Vorschlussbewegungsphase in which the closing member on the projection attacking the bolt has moved to a first section, imposed by the closing member performs a pivotal movement, and thereby acting on a projection of the bolt attacking the bolt displaced by a second section. In detail, the so-increased bolt precaution takes place in that with a key or with a knob or with an electric drive, the closing member of the lock cylinder is rotated. In a phase preceded by the first precompression phase, a tumbler is raised which holds the latch in the locked-back position. Subsequently, at the beginning of the first Vorschlussbewegungsphase, the closing member engages a first locking projection to vorzusperr the bolt to a first leg. This Vorschlussbewegungsphase is completed as soon as the closing member has overrun the first projection. Shortly before, simultaneously or shortly after, the closing member acts on a control shoulder of the feed lever articulated on the housing. An attack nose of the feed lever approaches while the bolt and lays down in front of a second projection, which can be arranged offset in the direction of movement of the bolt relative to the first projection. By sliding the closing member on the control shoulder of the feed lever pivoted. His nose acts on the second projection and drives the bolt into the fully vorgeschlossene position in which the tumbler can again assume their blocking position. For locking the lock the lock cylinder or the closing member is rotated in the opposite direction. It first engages the tumbler to dig it out and then on a flank to fully retract the latch. The projection may be formed by a slider which is displaced in the course of a panic function of a lifting mechanism such that the projection is outside the circular arc movement path of the closing member. This is advantageous in a panic lock, since then the closing member does not have the panic disturbing pivot position. The slider is preferably coupled for movement with the tumbler, so that concurrently with the lifting of the slider, the tumbler is lifted and the latch can be controlled back by a latch retracting arm, which is pivoted by operating the nut.

The lock shown in the figures has a lock case 1, the narrow side is provided with a forend 64. In the forend a first window is provided, in which a case 3 is mounted. The latch tail 8 of the case 3 is located within the lock case 1 and is acted upon by a latch spring 9 in trap position.

Below the case 3, a multi-part nut is mounted in the lock housing 1. The nut consists of a first nut half 4, which is assigned to an internal pusher can be and is rotatably connected to a Nussarmträger 6. Nussarmträger 6 and first half nut 4 are rotatable together about the pusher rotation axis. There is provided a second half nut 5 which is associated with an external handle. The second nut half 5 is not permanently coupled to the Nussarmträger motion. Like that FIGS. 6 to 8 can be seen, each of the two nut halves 4, 5 has a niche 69 and 68. The Nussarmträger 6 has an internal thread into which a pin 70 is screwed. The pin 70 can be selectively screwed into the lower or upper opening so that either the pin 70 is in the niche 68 or 69. With the pin 70 engaging in the recess 68 or 69, the corresponding nut half 4, 5 is motion-coupled to the nut arm carrier 6.

The two nut halves 4, 5 have a round opening with radial recesses, in each of which an insert 71, 72 can be inserted. The insert 71, 72 engages with radially projecting wings in the radial recesses and thus rotatably seated within the nut halves 4, 5. Each of the two inserts 71, 72 forms a square opening for insertion of a pusher mandrel.

The Nussarmträger 6 forms a first Nussarm 7, which carries at its end a clutch pawl axis 10 'to which a clutch pawl 10 is pivotally mounted. The coupling pawl 10 has a coupling shoulder 11, which lies in a non-operative position, in which the coupling pawl 10 is acted upon by the coupling spring 12, outside the movement path of a coupling flank 13 of the second half nut 5. In this non-operative position of the Nussarmträger 6 is not entrained in a rotation of the second half of the nut 5.

The coupling pawl 10 can be brought by pivoting about the coupling pawl axis 10 in a coupling position in which the coupling shoulder 11 is located in front of the coupling edge 13. In this coupling position is the Nussarmträger 6 with the second half nut 5 motion coupled. If the nut, and in particular the Nussarmträger 6, rotated by pressing the inner handle or by pressing the outer handle in the coupled position, the first Nussarm 7 engages a projection of the latch tail 8 to the case 3 against the restoring force of the latch spring. 9 to relocate to a withdrawn position.

In the lock housing 1, a coupling slide 14 is mounted. The coupling slide 14 is displaceable in the extension direction of the forend 64 in the lock and slides along the two long sides of the lock. The coupling slide 14 has a coupling flank 13 which can be brought against a control edge of the coupling pawl 10 to displace the coupling pawl 10 in the coupling position, wherein the clutch spring 12 is tensioned. In a Nichtwirkstellung the coupling edge 13 is spaced from the control edge of the clutch pawl 10, so that the clutch pawl 10 is held by the clutch spring 12 in the non-coupling position. The control edge of the coupling pawl 10 is located on the side facing away from the coupling shoulder 11 and extends approximately on a circular arc, so that the control cam during rotation of the nut on the coupling edge 13 can slide along and holds the clutch pawl 10 in the coupling position. For this purpose, the clutch pawl has an extended arm.

In the lock housing a locking pin 24 is resiliently mounted. For this purpose, the locking pin 24 is supported by a spring on the forend. The locking pin engages in a latching niche 23 of the coupling slide 14 to hold the coupling slide in the operative position.

At its lower end, the coupling slide 14 carries an actuating extension 17 (FIG. Fig. 12 ). The actuating extension 17 is mounted pivotably about a pivot axis 19 on the coupling slide 14. The actuating extension 17 is held by a leg spring 18 in a stop position and can be pivoted against the restoring force of the spring 18 about the pivot axis 19. The actuation extension 17 has two attack shoulders 17, 17 'converging at an acute angle. If the attack shoulder 17 'by a closing member 21 of a lock cylinder 20 which is inserted into a profile opening 22, applied, so the actuating extension 17 is supported on the stop, so that the coupling slide 14 by turning the closing member 21 from the non-operative position into the operative position is pushed, in which the coupling edge 13, the clutch pawl 10 moves into the coupling position and in which it is held by the latch 23, 24. The stop is formed by a stop pin 64 on which a stop shoulder 65 of the actuating extension 17 is supported. The actuating extension 17 has a pin 66. At the pin 66 and the stop pin 64, the two legs of the leg spring 18 are supported, which is mounted on the pivot axis 19 (see Fig. 12 ).

If the second attack shoulder 17 'is acted upon by the closing member 21, then it can dodge, so that this is an escape shoulder 17 ".

The escape shoulder 17 "can escape in particular if the closing member 21 lies in the path of movement of the actuating extension 17 when the coupling slider 14 is displaced upwards, then the escape shoulder 17" acts on the closing member 21 and deviates elastically. Such a situation is in the Fig. 22 indicated. This figure shows a state of movement achieved by turning the first half nut 4 at a locked bar 2. The displaced in the pre-closed locking position down clutch slide 14 is displaced upward in the course of the panic function. Located in the path of movement of the actuating extension 17, the closing member 21, the closing member 21 is acted upon by the escape shoulder 17 ", so that the actuating extension 17 against the restoring force of Leg spring 18 can escape, with the stop shoulder 65 spaced from the stop pin 64.

In a second window of the faceplate is a bolt 2, which can be transversely to the extension direction of the forend 64 back and closed. This is done with the aid of the closing member 21 of the lock cylinder 20. The bolt has a projection 26 on which the closing member 21 can engage. Rearward of the projection 26 is located on the latch 2 a tumbler 50 which is formed by a tumbler, which can be moved transversely to the latch displacement direction of the closing member 21 when the closing member 21 acts on a cam 54 of the tumbler 50. The tumbler 50 has a touring projection 51, which lies in the blocking position of the tumbler 50 in the rearward locking position in a tour recess 52 and which lies in a pre-closed locking position in a tour recess 53. The two tour recesses 52 and 53 are formed by a projection of the lock rear wall.

After lifting the tumbler 50, the closing member 21 occurs against the projection 26 which is formed by a slide 27 which is displaceable parallel to the tumbler 50 and the entrainment 50 entrains in a shift. The control cam 54 ends in the region of the projection 26, so that the tumbler 50 is excavated when the closing member reaches the projection 26. In the following movement phase ( Fig. 15 . 16 ), the bolt 2 is entrained by the rotational movement of the closing member 21 in the direction of prefix until the closing member 21 has overflowed the projection 26. In the subsequent movement phase of the closing member 21 (FIG. Fig. 17 ) The closing member runs against a feed lever 43. The feed lever forms a control shoulder 47, on which slides the closing member along, wherein the feed lever 43 pivots about its housing-fixed pivot axis 44. The pivot axis 44 of the feed lever 43 is located between the insertion opening 22 and the forend 64. The feed lever 43 is acted upon by a spring in the direction of the closing member 21. There is provided a Bewegungsendanschlag, which is formed by an engaging in an arcuate slot 46 pin 45.

If, in the second movement phase, the feed lever 43 is acted upon by the closing member, its engaging nose 48 arranged on the arm end engages a second projection 49 of the bolt 2. Also, this projection 49 is formed by the slider. However, it is in front of the first projection 26 vorverlagert in the direction of the locking bolt, so that a safe movement takeover by the feed lever 43 takes place when the closing member 21 has overrun the associated projection 26. In the second movement phase, the bolt 2 is moved by the feed lever 43 by a second partial amount to the end position ( Fig. 18 ), wherein on the control shoulder 47, the closure member engages in its rotation.

The follower has a second Nussarm 34, which is also associated with Nussarmträger 6. In a bearing eye 40 of the second Nussarmes 34 supports a pin 39 to which a tension member 36 is articulated. To a housing-fixed axis of rotation 35, a lever 28 is mounted, which is a lifting arm 28. The lifting arm 28 has a in its extension direction between the pivot axis 35 and arranged at the end of the lifting arm 28 lifting pin 29 longitudinal slot 38. In the longitudinal slot 38 engages a pin 37 of the tension member 36 a. If the nut and in particular the Nussarmträger 6 is pivoted by handle operation, so is shifted from the pivoting second Nussarm 34 via the tension member 36 of the lifting arm 28 upwards. The lifting pin 29 engages a lifting shoulder 27 'of the slider 27 and displaces the slider 27 transversely to the direction of displacement of the bolt against the restoring force of a spring 30, provided that the bolt 2 is in the fully pre-closed position. The Figures 9 and 10 It can be seen that the slider 27, the projection 26 and a projection 61 spaced from the edge forms. in the Area of the flank 61 is also a shoulder 74, on which an extension 75 of the tumbler 50 rests. If the slide 27 is pulled upward, the leg spring 30 is tensioned and the tumbler 50 is dragged along. In this case, the tumbler spring 73 is stretched.

The second Nussarm 34 carries a drive pin 41, the movement delayed with respect to the pivoting movement of the lifting arm 28 a latch retraction lever 25 is applied. The bolt retraction lever 25 is pivotally mounted about the pivot axis 35 about which also the lifting arm 28 is mounted. A longer arm of the latch retracting lever 25 engages a control pin 55 of the bolt 2, which is guided in a guide slot 56 of the lock floor. If the bolt retraction lever 25 is pivoted, the bolt 2 located in the locked-in locking position is displaced into the locked-back position. Previously, with the lifting pin 29, the slider 27 is lifted into a locking position, in which a latching pin 31 engages in a latching niche 32 of the slider 27. This is spring loaded. Along with the lifting of the slider 27, the tumbler 50 is lifted to a release position, so that the touring projection 51 steps out of the tour recess 53. Shortly before the latch 2 assumes its closed-back end position, a trigger 33 enters against the lock rear wall and displaces the latching pin 31 out of the latching recess 32 so that the spring 30 moves the slide 27 back into the starting position.

The follower is associated with a pusher spring 57, which is supported on a housing-fixed block 60. It is penetrated by a bearing pin 59, which is supported on a support shoulder 58 of both the outer and the inner half of the nut.

The fully precluded bolt can also be closed back by means of the closing member 21. For this purpose, the closing member 21 initially undercuts the cam 54 to lift the tumbler. Then that beats Closing member 21 on the flank 61 to retract the latch. The flank 61 is formed by the slider 27, which also forms a projection 63 which enters into a recess 62 when the slider 27 is lifted.

The operation of the castle is the following:

In a Nichtwirkstellung the coupling slide 14 ( Fig. 1 . 13 ), the latch 3 can be withdrawn only by operating the internal presser, since only the first half nut 4 is motion coupled to the Nussarmträger 6. The second half nut 5 is not motion coupled to the Nussarmträger 6. If a door equipped with the lock 1 is to be actuated from the outside, the lock cylinder 20 must first be rotated in the opening direction so that the closing member 21 comes against the engagement shoulder 17 'of the actuation extension 17 and displaces the coupling slide 14 upwards. In the upwardly displaced active position ( Fig. 14 ), the coupling slide 14 is held by the latch 23, 24. In this operative position, the coupling flank 13 acts on the coupling pawl 10 in the coupling position, so that the second half nut 5 is coupled in a motion-coupled manner to the nut arm carrier 6. Now, if the nut and Nussarmträger 6 is rotated, the Nussarm 7 attacks on the latch tail 8 to pull back the trap. The trap can now be retracted both by turning the inner nut half 4 and the outer nut half 5. The door equipped with the lock can thus be opened from both sides.

If the lock is to be locked, this is done by operating the lock cylinder 20 and turning the closing member 21 in the closing direction. The closing member 21 first lifts the tumbler 50 and then engages the projection 26 to precede the bolt 2 by a first displacement path ( Fig. 15 . 16 ). Along with this occurs a control pin 16 of the bolt 2 against a first control cam 15 ', which is formed by a V-shaped notch 15 of the coupling slide 14. The coupling slide 14 is thereby from the operative position brought into a non-operative position and shifted down. The clutch pawl 10 is out of action.

The first movement phase is followed by the second movement phase, in which the bolt 2 is advanced by the feed lever 43. After complete advancement of the bolt 2, the touring projection 51 engages in the Tourenausnehmung 53. After reaching the in the FIGS. 15 and 16 shown intermediate position leaves the closing member 21, the projection 26 and slides on the control shoulder 47 of the feed lever 43 along as it Fig. 17 shows. Along with it, the feed lever 43 is pivoted, so that its attack nose 48 can engage the projection 49 to the further rotation of the closing member 21, the bolt 2 in the in the Fig. 18 to shift shown bolt locking position.

There are two ways to relocate the bolt 2 from the vorgeschlossenen position. The first, also possible from the outside variant is that the closing member 21 is rotated in the opening direction. After lifting the tumbler 50 it comes against the flank 61 (see Fig. 24 ) and relocates the bolt 2 again in the back-closed position. In this case, the control pin 16 occurs against a second control cam 15 "of the V-shaped recess and displaces the coupling slide 14 in an initial position corresponding to a Nichtwirkstellung in which the closing member against the attack shoulder 17 'can occur.

The second variant of the latch yoke is the panic function. This is only possible from the inside and the first half of the nut 4. The rotation of the first nut half 4 leads to an upward movement of the lifting pin 29, which engages under the lifting shoulder 27 'of the slider 27 ( Fig. 20 ). Along with this, the slider 27 is raised until the catch 31 enters the latching niche 32. In this position, the projection 26, on which the closing member 21 engages in the Vorschlussbewegung, outside the circular arc trajectory of the Closing member 21. There is thus no movement-disturbing rotational position of the closing member 21, in which the projection 26 could occur at the locking latch against the closing member.

Once the latching pin 31 has entered the latching niche 32, the latch retraction lever 25 is acted upon and pivoted by the drive pin 41, such that its longer arm on the control pin 55 of the bolt 2 attacks ( Fig. 21 ). The bolt 2 is moved to the back-closed position, wherein in the final phase of the trigger 33 abuts the lock back and the locking pin 31 is released from the latching niche 32, so that the tensioned when lifting the slider 27 spring 30, the slider 27 can shift back again. In the Fig. 22 dash-dotted lines the circular arc movement path 77 of the closing member 21 is shown. With 21 ', a position of the closing member is shown, in which it rests against the attack nose 48 of the feed lever 42. The attack nose 48 acts as a stop, so that the closure member 21 'can not be rotated in the opening direction. If the locking element 2 is retracted in the closing element 21 ', then the closing element can be acted upon by the tumbler 50 or by a rear extension of the slide 27 forming the flank 61. The closing member 21 'is then slightly pivoted, which in the Fig. 23 is shown. If pivoting is not possible, the slide 27 or the tumbler 50 can move upwards against the restoring force of the spring 73 or 30.

Along with the return displacement of the bolt 2, the control pin 16 slides along the second control cam 15 "and displaces the coupling slider 14 upwards, but not into the operative position Dodge shoulder 17 "of the actuating extension 17 acted upon. However, since the actuating extension 17 but when his evasive shoulder 17 "can escape against the restoring force of the spring 18, the panic function is not blocked by this closing member position.

Of the Fig. 22 It can be seen that the lower edge of the slider 27 is in its upwardly displaced position above the circular arc path 77. However, the escape shoulder 17 "intersects the circular arc trajectory 77 during the upward displacement of the coupling slide 14. It slides on the closing element 21 engaging a collision position and deviates from the restoring force of the spring 18.

Is the closing member 21 in the in Fig. 23 With a solid line position shown, so in a position between the projection 26 and edge 61, this does not lead to a blockage of the panic function, since the projection 26 has been brought by the lifting of the slider 27 from the circular arc movement path 77.

Fig. 24 shows the key-operated latch retraction, wherein the closing member 21 engages the flank 61. A further rotation of the closing member 21 leads to the in Fig. 25 shown operating position in which the closing member 21 on the flank 61 attacking the bolt 2 moves further into its rückgeschlossene end position.
