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 In the locked position, a trap can be withdrawn by the operation of a pusher.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. If the inner handle is actuated when the locked position is locked, the latch is retracted by a latch retraction arm. 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The DE 10 2005 039 287 B4 describes an anti-panic lock, in which the pre-locked bar can also be withdrawn by pressing a pusher nut. In order to operate this lock from the outside, an exchange function is provided with which the case can be withdrawn by key operation.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 forth a change operation in a lock according to the prior art. 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 control cam, the coupling slide can be brought out of its operative position at the conclusion of the bolt. 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. However, by the projection is associated with a slider which is outside the arc 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 enlarged bolt lock 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 is 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.

25 a follow-up presentation to 24 with latch further closed by key operation 2 ,

The lock shown in the figures has a lock case 1 whose narrow side with a forend 64 is provided. In the forend a first window is provided, in which a trap 3 is stored. The trap tail 8th the trap 3 is located inside the lock box 1 and is from a falling spring 9 acted in Fallvorstellungstellung.

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

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

The nut arm carrier 6 forms a first nut arm 7 out, which at its end a clutch pawl axis 10 ' carries to the one clutch pawl 10 is pivotally mounted. The clutch pawl 10 has a coupling shoulder 11 in an out-of-position position in which the clutch pawl 10 from the clutch spring 12 is applied, outside the trajectory of a coupling edge 13 the second nut half 5 lies. In this position, the Nussarmträger 6 upon rotation of the second nut half 5 not dragged along.

The clutch pawl 10 can by pivoting about the clutch pawl axis 10 be brought into a coupling position in which the coupling shoulder 11 in front of the coupling flank 13 lies. In this coupling position is the Nussarmträger 6 with the second nut half 5 motion-coupled. Will the nut, and especially the Nussarmträger 6 , rotated by operating the inner handle or by pressing the outer handle in the coupled position, so engages the first Nussarm 7 at a projection of the tail-tail 8th to the trap 3 against the restoring force of the latch spring 9 to relocate to a withdrawn position.

In the lock housing 1 is a coupling slider 14 stored. The coupling slider 14 is in the extension direction of the forend 64 relocatable in the castle and glides along the two long sides of the castle. The coupling slider 14 has a coupling edge 13 , which against a control edge of the clutch pawl 10 can be brought to the clutch pawl 10 to shift to the coupling position, wherein the clutch spring 12 is tense. In a Nichtwirkstellung is the coupling edge 13 from the control edge of the clutch pawl 10 spaced so that the clutch pawl 10 from the clutch spring 12 held in the non-coupling position. The control edge of the clutch pawl 10 located on the coupling shoulder 11 On the opposite side and runs approximately on a circular arc, so that the cam when turning the nut on the coupling edge 13 can slide along and the clutch pawl 10 holds in the coupling position. For this purpose, the clutch pawl has an extended arm.

The lock housing is a detent pin 24 spring-mounted. For this purpose, the locking pin is supported 24 with a feather on the forend. The detent pin engages in a detention niche 23 the coupling slide 14 to hold the coupling slide in the operative position.

At its lower end carries the coupling slide 14 an actuating extension 17 ( 12 ). The actuating extension 17 is about a pivot axis 19 swiveling on the coupling slider 14 stored. The actuating extension 17 is from a thigh spring 18 held in a stop position and can against the restoring force of the spring 18 around the pivot axis 19 be pivoted. The actuating extension 17 has two attack shoulders converging at an acute angle 17 . 17 ' , Will the attack shoulder 17 ' from a closing member 21 a lock cylinder 20 in a profile opening 22 is plugged in, acted upon, so the actuating extension is supported 17 off at the stop, leaving the coupling slide 14 by turning the closing element 21 is pushed from the non-operative position into the operative position in which the coupling edge 13 the clutch pawl 10 moved into the coupling position and in the rest of the rest 23 . 24 is held. The stop is from a stop pin 64 formed, on which a stop shoulder 65 of the actuating extension 17 supported. The actuating extension 17 owns a pin 66 , At the tap 66 and at the stop pin 64 support the two legs of the leg spring 18 off, on the pivot axis 19 is stored (see 12 ).

Will be the second attack shoulder 17 ' from the closing member 21 so she can dodge, so this is an evasion shoulder 17 '' is.

The evasion shoulder 17 '' In particular, it is possible to avoid it when shifting the coupling slide upwards 14 the closing member 21 in the trajectory of the actuating extension 17 lies. Then the alternate shoulder impinges 17 '' the closing member 21 and evades elastic. Such a situation is in the 22 indicated. This figure shows a state of movement by turning the first nut half 4 at a locked latch 2 is reached. The in the vorgeschlossenen bolt position down shifted coupling slide 14 is shifted upwards in the course of the panic function. Located in the trajectory of the actuating extension 17 the closing member 21 so becomes the closing member 21 from the evasion shoulder 17 '' applied, so that the actuating extension 17 against the restoring force of the leg spring 18 can dodge, with the stop shoulder 65 from the stop pin 64 spaced.

There is a catch in a second window of the forend 2 , which is transverse to the extension direction of the forend 64 can be closed and closed. This is done with the help of the closing member 21 of lock cylinder 20 , The bolt has a projection 26 to which the closing member 21 can attack. Rearward of the projection 26 is on the bar 2 a tumbler 50 , which is formed by a tumbler, the transversely to the latch displacement direction from the closing member 21 can be moved when the closing member 21 a control curve 54 the tumbler 50 applied. The tumbler 50 owns a tour lead 51 which is in the blocking position of the tumbler 50 in the rearward latch position in a tour recess 52 lies and in a vorgeschlossenen latch position in a touring recess 53 lies. The two tour recesses 52 and 53 are formed by a projection of the lock rear wall.

After lifting the tumbler 50 occurs the closing member 21 against the lead 26 that of a slider 27 is formed, which is parallel to the tumbler 50 is displaceable and in a relocation the tumbler 50 drags. The control curve 54 ends in the area of the projection 26 so the tumbler 50 is dug when the closing member the projection 26 reached. In the following movement phase ( 15 . 16 ) becomes the bar 2 from the rotational movement of the closing member 21 entrained in the direction of conclusion until the closing member 21 the lead 26 overflowed. In the subsequent movement phase of the closing member 21 ( 17 ), the closing member runs against a feed lever 43 , The feed lever forms a control shoulder 47 from where the closing member slides along, wherein the feed lever 43 around its housing-fixed pivot axis 44 pivoted. 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 with a spring in the direction of the closing member 21 applied. There is provided a movement end stop, from one to an arched slot 46 engaging pin 45 is formed.

Is in the second movement phase of the feed lever 43 acted upon by the closing member, so engages the arranged at the end of the arm attack nose 48 at a second projection 49 of the bolt 2 at. Also this advantage 49 is formed by the slider. He is, however, opposite the first lead 26 vorverlagert in the final direction of the bolt, so that a safe movement of movement by the feed lever 43 takes place when the closing member 21 his assigned lead 26 overflowed. In the second movement phase, the bolt 2 from the feed lever 43 by a second partial amount to the end position ( 18 ), being at the tax shoulder 47 the closing member attacks during its rotation.

The handle has a second nut arm 34 , who is also the Nussarmträger 6 assigned. In a bearing eye 40 of the second nut arm 34 stores a cone 39 on which a tension member 36 is articulated. To a housing-fixed axis of rotation 35 is a lever 28 stored, which is a lifting arm 28 is. The lifting arm 28 has one in its extension direction between the pivot axis 35 and one at the end of the lift arm 28 arranged lifting pins 29 extending longitudinal slot 38 , In the longitudinal slot 38 grab a pin 37 of the tension member 36 one. Will the nut and especially the Nussarmträger 6 pivoted by handle operation, so is from the pivoting second Nussarm 34 over the tension member 36 the lifting arm 28 shifted upwards. The lifting pin 29 engages a lifting shoulder 27 ' of the slider 27 and shifts the slider 27 transverse to the direction of displacement of the bolt against the restoring force of a spring 30 if the bolt 2 in the fully closed position. The 9 and 10 it can be seen that the slider 27 the lead 26 and a flank spaced from the protrusion 61 formed. In the area of the flank 61 there is also a shoulder 74 on which an extension 75 the tumbler 50 rests. Will the slider 27 pulled up, so the leg spring 30 cocked and the tumbler 50 dragged. This is also the tumbler 73 curious; excited.

The second nut arm 34 carries a drive pin 41 , which is delayed in movement with respect to the pivoting movement of the lifting arm 28 a latch retracting lever 25 applied. The latch retracting lever 25 is about the pivot axis 35 to which also the lifting arm 28 is stored, pivotally mounted. A longer arm of the latch retracting lever 25 engages on a control pin 55 of the bolt 2 at that in a guide slot 56 led the castle floor. Will the latch retracting lever 25 pivoted, so is the lying in the vorschlußen latch position latch 2 moved to the locked position. Previously, with the lifting pin 29 the slider 27 lifted into a detent position in which a locking pin 31 in a detention niche 32 of the slider 27 intervenes. This is spring loaded. Along with lifting the slider 27 becomes the tumbler 50 lifted into a release position, so the touring protrusion 51 from the Tourenausnehmung 53 occurs. Just before the bar 2 takes his back-closed end position, a trigger occurs 33 against the rear wall of the castle and displaces the locking pin 31 from the break niche 32 so the spring 30 the slider 27 moved back to the starting position down.

The follower is a pusher spring 57 assigned to a housing-fixed little bucks 60 supported. It is from a storage pen 59 attacked, attached to a support shoulder 58 supporting both the outer and the inner half of the nut.

The fully locked bolt can also with the help of the closing member 21 be closed back. For this purpose, the closing member underflows 21 first the control curve 54 to dig out the tumbler. Subsequently, the closing member strikes 21 on the flank 61 to retract the latch. The flank 61 gets off the slider 27 trained, who also has a lead 63 which forms when lifting the slider 27 in a niche 62 entry.

The operation of the castle is the following:
In a non-operative position of the coupling slide 14 ( 1 . 13 ) can the trap 3 can only be withdrawn by pressing the inner handle, since only the first half of the nut 4 with the Nussarmträger 6 is motion coupled. The second nut half 5 is not with the Nussarmträger 6 motion-coupled. Should one with the lock 1 equipped door to be operated from the outside, so must first the lock cylinder 20 be rotated in the opening direction, so that the closing member 21 against the attack shoulder 17 of the actuating extension 17 occurs and the coupling slide 14 shifted upwards. In the upwardly displaced active position ( 14 ) becomes the coupling slide 14 from the rest 23 . 24 held. In this operative position acts on the coupling edge 13 the clutch pawl 10 in the coupling position, leaving the second nut half 5 with the Nussarmträger 6 motion coupled. Now the nut and the Nussarmträger 6 turned, the nut arm grabs 7 on the tail-tail 8th to pull the trap back. The trap can now both by turning the inner nut half 4 as well as the outer nut half 5 be withdrawn. The door equipped with the lock can thus be opened from both sides.

If the lock is to be locked, this is done by pressing the lock cylinder 20 and turning the closing member 21 in the closing direction. The closing element 21 first raises the tumbler 50 and then picks up the lead 26 to the latch 2 to complete a first relocation route ( 15 . 16 ). Along with it enters a control pin 16 of the bolt 2 against a first cam 15 ' that of a V-shaped incision 15 the coupling slide 14 is formed. The coupling slider 14 is brought out of the operative position in a non-operative position and shifted downwards. The clutch pawl 10 occurs out of action.

The first movement phase is followed by the second movement phase, in which the bolt 2 through the feed lever 43 is relocated. After complete advancement of the bolt 2 snaps the tour tab 51 in the Tourenausnehmung 53 , After reaching the in the 15 and 16 shown intermediate position leaves the closing member 21 the lead 26 and slides on the tax shoulder 47 of the feed lever 43 along, like that 17 shows. Along with this is the feed lever 43 pivoted so that its attack nose 48 at the lead 49 can attack to continue turning the closing member 21 the bolt 2 in the in the 18 to shift shown bolt locking position.

There are two options, the bolt 2 to relocate from the preconnected position. The first, also possible from the outside variant is that the closing member 21 is rotated in the opening direction. After removal of the tumbler 50 it kicks the flank 61 (please refer 24 ) and relocates the bars 2 back into the locked position. In this case, the control pin occurs 16 against a second cam 15 '' the V-shaped niche and shifts the coupling slide 14 in a starting 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 from the inside and over the first half of the nut 4 possible. Turning the first nut half 4 leads to an upward movement of the lifting pin 29 , the lifting shoulder 27 ' of the slider 27 engages ( 20 ). This is followed by the slider 27 raised until the rest 31 in the detention niche 32 entry. In this position lies the projection 26 , at which in the Vorschlussbewegung the closing member 21 attacks, outside the circular arc trajectory of the closing member 21 , There is thus no movement-disturbing rotational position of the closing member 21 into which the lead 26 could occur against the closing member at the bolt conclusion.

Once the locking pin 31 in the detention niche 32 has occurred, the latch retracting lever 25 from the drive pin 41 acted upon and pivoted, so that his longer arm on the control pin 55 of the bolt 2 attacks ( 21 ). The bolt 2 is shifted to the locked position, with the trigger in the final phase 33 abuts the lock back and the locking pin 31 from the break niche 32 freed, so that when lifting the slider 27 cocked spring 30 the slider 27 can relocate again. In the 22 is dot-dashed the circular arc trajectory 77 of the closing member 21 shown. With 21 ' a position of the closing member is shown in which it is on the attack nose 48 of the feed lever 42 is applied. The attack nose 48 acts as a stop, allowing the closing member 21 ' can not be rotated in the opening direction. Will be in the position 21 ' standing closing element of the bolt 2 retracted, so the closing member of the guard locking 50 or from a backward, the flank 61 forming extension of the slider 27 be charged. The closing element 21 ' is then slightly pivoted, resulting in the 23 is shown. If pivoting is not possible, then the slider 27 or the tumbler 50 upwards against the restoring force of the spring 73 respectively. 30 dodge.

Along with the relocation of the bolt 2 slides the control pin 16 at the second cam 15 '' along and shifts the coupling slide 14 to the top, but not to the active position. Should the closing member 21 in the trajectory of the actuating extension 17 lie, so it gets from the evasion shoulder 17 '' of the actuating extension 17 applied. As the actuating extension 17 but when his evasion shoulder 17 '' against the restoring force of the spring 18 can escape, the panic function is not blocked by this closing member position.

Of the 22 can be seen that the lower edge of the slider 27 in its upwardly displaced position above the circular arc trajectory 77 lies. The evasion shoulder 17 '' However, crosses in the upward displacement of the coupling slide 14 the circular arc trajectory 77 , It slides on the closing element occupying a collision position 21 and deviates from the restoring force of the spring 18 out.

Is the closing member 21 in the in 23 with a solid line position shown, so in a position between projection 26 and flank 61 So this does not lead to a blockage of the panic function because of the lead 26 by lifting the slider 27 from the circular arc trajectory 77 has been brought.

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