Description

The invention relates to a lock with a multi-part nut, which has a first Nusshälfte for inserting a first Pusher Halbdomes and a second Nusshälfte for inserting a second Pusher half-mandrel, wherein the two Nusshälften and a locking element to the withdrawal of the same retracting lever are pivotable about a common axis Optionally, one of the two nut halves is permanently rotationally coupled to the return lever, the return lever carrying a coupling pawl urged by a clutch pawl spring into a disengaged position and a pusher operable by a lock cylinder in a coupled position with the respective one another nut half can be brought, in which the retraction lever is rotationally coupled to the other half of the nut.

The EP 0 537 531 describes a bolt lock in which a pivot bolt by actuation of a nut, which is formed in several parts, can be withdrawn. The nut has two nut halves arranged coaxially one behind the other and a retraction lever arranged between the two nut halves. The retraction lever can be coupled to one of the two nut halves in order to transmit a torque, which is applied by a trigger handle via a trigger half-mandrel on the nut half, on the pull-back lever acting on the pivot bolt. The lock also has a slide which is mounted displaceably along a cuff in the lock housing. The slider can be displaced from the closing member of a lock cylinder. During its displacement, it acts on a coupling pawl, which couples a nut half with the return lever.

From the DE 195 42 026 C1 a lock with a two-part nut is known in which the nut can also be operated either from the inside or from the outside.

From the DE 198 42 279 A1 is known a drive rod lock, in which the Fallenbetätigbarkeit is umstellbar. This castle also has a multipiece nut.

The EP 1 437 464 A1 discloses a lock according to the preamble in which a latch is provided which locks the latch in its advanced position. This consists of a pivotally mounted in the lock housing lever which is pivoted via a pin-link control. The gate follower is assigned to the return lever and is operated as such together with one of the nut halves. These Design requires in addition to a variety of matched components high operating forces.

Based on the aforementioned prior art, the present invention seeks to provide a functional escape door lock.

The problem is solved by the combination of features specified in claim 1.

The claim 1 provides initially and essentially to the characterizing part of claim 1, that the slider forms a trap in its position of closure locking arm, wherein a Schieberverlagerungsarm acts on the slide before a Fallenrückzugsarm of the retraction lever acts on a tail of the trap to the Move blocking arm from a blocking position before the attack of the trap retracting arm on the tail-tail. The escape door lock equipped in this way can have an inside handle and an outside handle. The inner pusher is rotationally coupled to the other half of the nut with a first pusher half arbor with one half of the nut and the outside pusher with another pusher half arbor. One of the two nut halves, namely the nut half associated with the internal pusher, is permanently coupled to the return lever, so that the trap can always be closed from the inside. The closure also has a sliding latch, which can be closed by a lock cylinder back and forth. This lock cylinder is also able to relocate a slide arranged in the lock housing. The displacement preferably takes place along the faceplate and transversely to the direction of displacement of the latch or bolt. This slide cooperates with the coupling pawl to couple the other half of the nut to the return lever when the slide is displaced. The slider can also form a blocking arm that can block the trap in its closed position. The sliding displacement arm of the retraction lever then pre-controlled attacks on the slide to herausververlagern the blocking arm out of the range of motion of the nut. Only then does the retraction lever engage the latch tail to retract the latch.

In a further development, it is provided that the coupling of the other half of the nut with the return lever is achieved by turning the nut half, which is permanently coupled to the return lever. There are provided for this purpose in the castle measures that the slide is displaced even with such a nut operation. In a variant of the invention it is provided that the coupling pawl is displaceable exclusively by Schliesszylinderbetätigung in the coupling position. A handle operation is not enough. Furthermore, it can be provided that the pre-closed latch is controlled back into the lock housing by acting on its end face. In a variant of the invention provided that this positively controlled latch return displacement leads to a coupling of the other half of the nut with the retraction lever. It is envisaged that the retraction lever is mounted between the two nut halves. He can wear a journal on both broadsides or preferably only on one of its two broad sides. To this journal, a single clutch pawl can be pivotally mounted. This may have a parallel to the nut axis extending coupling bar. This coupling bar can rotate both halves of the nut with the retraction lever in the coupling position. According to this embodiment, a conversion of each permanently coupled to the retraction lever nut half in a simple manner possible. The permanent coupling can be achieved, for example, by means of a screw whose head lies in a coupling opening of the one half of the nut and which is screwed with its shaft into a threaded opening of the retraction lever. The screw then only needs to be loosened in order to be screwed back into the pull-back lever from the other side so that its screw head lies in the coupling recess of the other nut half.

It is further provided that the slide is a espagnolette slide and / or an auxiliary slide, with which the parts of a multi-part nut are coupled together so that a case of both an outside pusher and an internal pusher is retractable. The auxiliary slide can be held by a latch associated with the locking cam in one of its two Schubendstellungen detent.

The coupling pawl may have a control cam on which a control projection of the coupling slide engages. This control cam can run in the coupling position on a circular arc line around the nut axis, so that it can slide on the control projection when the nut is rotated.

The coupling pawl spring, which acts on the coupling pawl out of its coupling position, can be mounted on the lock housing. It is preferably formed by a torsion spring, which is mounted around a housing-fixed pin. In the slide, which can also be referred to as a coupling slide, it may be a drive rod slide or an auxiliary slide. This slide acting as a coupling slide can be acted upon by a slide displacement arm of the retraction lever. Such an act can be done, for example, to shift the slide by nut operation in the coupling position. In a further development of the invention it is provided that the espagnolette connection slide forms the coupling slide. This can carry a control pin which acts on the control cam of the clutch pawl. If the control pin is removed, the espagnolette slide loses its function as a coupling slide. In this case, the function of the Coupling slide a parallel to the espagnolette slide in the lock housing movable auxiliary slide. This also has a control pin. The auxiliary slide can shift exclusively by Schliesszylinderbetätigung the clutch pawl in the coupling position. In this variant, it is ensured that the outer handle can be activated only by willpower by Schliesszylinderbetätigung. A positively controlled latch conclusion does not lead to an activation of the external handle. Furthermore, measures may be provided to hold the auxiliary slide in its coupling position acting on the coupling position. It can be a rest. In this embodiment, the slider remains in its position effecting the coupling until it is displaced back by a bolt lock. In an alternative can be dispensed with the catch. The slide then falls either gravity-controlled or spring-force controlled after cancellation of the action by the lock cylinder back into a decoupled position. The coupling pawl may be disposed on a slide displacing arm of the retracting lever. The coupling bar can sit at the end of the coupling pawl. However, leverage technically more favorable, it is when the coupling element, ie in particular the coupling bar between the cams and the bearing pin of the clutch pawl is arranged. The coupling pawl has in particular an arched shape. Approximately in the middle of the bow sits the coupling beam. In this embodiment, the bearing pin can be assigned to the Fallenrückzugsarm, so that is arranged in the mounted position of the bearing pin above the coupling beam and the control cam.

The slider may be a driving rod connection slide and held by means of a latch in a release position. The slider can also be held in its blocking position by a latch.

Other possible embodiments of a castle, which according to the position in FIG. 1 are shown.

Essentially, the inventive lock 1 consists of a lock housing 2 and the Schlosseingerichte. The lock housing 2 is composed of a faceplate 3, a lock bottom 4, a receiving body 5 arranged thereon and a lock cover (not illustrated here).

The Schlosseingerichte consists essentially of a case 6, a multi-part nut 7, a driving rod connecting slide 8, a parallel to the case 6 arranged latch 9 and a drivable by a lock cylinder 10 rotational transmission member 92, 93rd

The face-plate 3 has a case passage opening and a latch passage opening. These are the case 6 and the latch 9 adapted. The faceplate 3 is fixed by screws 11 or other suitable connecting means, such as rivets on the lock bottom 4. The receiving body 5 is fixed by means of fixing pins 12, which emanate from the lock bottom 4 on this. The receiving body 5 is designed such that it the intermediate space between the lock bottom 4 and the lock cover, not shown fills. In the fixing pin 12, a threaded bore 13 is arranged. The lock cover can by means of fastening screws which engage in the threaded bore 13, are screwed onto the receiving body 5. The lock bottom 4 and the lock cover clamp the receiving body 5 between them.

The trap 6 forms a trap head 14 and a cylindrical latch tail 15. The latch tail 15 has a square body 16 at its rear free end. The rectangular, in particular square body 16 is fastened to the latch tail 15 by means of a fastening screw (not illustrated here). The body 16 is eccentrically in the direction of the present under the trap 6 multi-piece nut 7, extended. In this area, the body 16 forms an operating portion 17. At the operating portion 17, a Fallenrückzugsarm 38 of a retraction lever 23 of the multi-part nut 7 attack. On the body 16 engages a latch spring 18. The latch spring 18 is located between the square body 16 and the receiving body 45. The latch spring 18 is arranged centrally to the cylindrical latch tail 15. The cylindrical latch tail 15 is received by a shape-adapted receptacle 19 of the receiving body 5. The shape-adapted receptacle 19 is arranged in a web portion 20 of the receiving body 5. The side of the web portion 20, which faces the square body 16, forms a stop 21 for the case 6.

The case 6 is reversible as in principle from the prior art in order to be used for both right and left-closing doors. For this purpose, the case head 14 can be pulled out of the face opening to 180 °. be rotated and relocated again.

Below the previously described case 6 is the multipiece nut 7. This is in the FIGS. 5 to 11 shown in more detail. The multi-part nut 7 essentially consists of a first nut half 22, a retraction lever 23 arranged underneath and a second nut half 24 arranged below the retraction lever 23. The first nut half 22 and the second nut half 24 each have a square depression 25 (see FIG FIG. 7 ). It is also good to see that the recesses 25 are closed to the parting plane T of the two nut halves 22, 24 in each case by a bottom 26. In the bottom 26 a circular through hole 27 is arranged in each case. In the square recesses 25 each a Pusher half arbor of a door handle, not shown here can be inserted.

In essence, the multi-part pusher 7 has a circular outer contour. The two nut halves 22, 24 are configured essentially mirror-inverted to the common parting plane T. The two nut halves 22, 24 each form a large comb 28 and a small crest 29 off. The large comb 28 has a larger outer diameter than the small comb 29. In the large comb 28 an open-edged recess 30 is incorporated. As in FIG. 6 can be seen well, approximately the open-edged recess 30 is arranged centrally to the square recess 25. In the clockwise direction, starting from the open-edged recess 30 is a stop 31. Furthermore, the small comb 29 also forms a stop 32. How good in the Figures 5 and 7 can be seen, both nut halves 22, 24 form a diameter-reduced cylindrical portion 33 toward the parting plane T out. The cylindrical portion 33 of each nut half 22, 24 has half the height of the retracting lever 23. With the cylindrical portions 33 of the retraction lever 23 is received. On the broad side, which is averted from the parting plane T, the two nut halves 22, 24 each form a further cylindrical section 33 '. These serve to receive the multi-part nut 7 in the openings provided for this purpose 105 in the lock bottom 4 or in the lock cover (see FIG. 7 ).

The pull-back lever 23 has a receiving bore 34 adapted to the cylindrical sections 33. In essence, the retraction lever 23 forms the same basic contour as the two nut halves 22, 24. At the position where the recess 30 is arranged at the two nut halves 22, 24, there is a threaded through-bore 35 in the pull-back lever 23. A shaft screw 36 can be screwed into the threaded through-bore 35. In the screwed-in state, the head 37 of the shaft screw 36 projects into one of the two open-edged recesses 30 of the respective nut half 22, 24. By the shaft screw 36, one of the two nut halves 22, 24 is rotationally coupled to the retraction lever 23. In the embodiments, the retraction lever 23 is rotationally coupled to the first nut half 22. In the direction of rotation of the rear threaded through hole 35, a Fallenrückzugsarm 38 is arranged. Furthermore, the retraction lever 23 forms a slide displacement arm 39. On the upper broad side of the Schieberverlagerungsarms 39 a bearing pin 40 is arranged. Between the Fallenrückzugsarm 38 and the Schieberverlagerungsarm 39 of the retraction lever 39 forms a holding table 41, which also acts as a coupling niche. The two nut halves 22, 24 and the return lever 23 are pivotally mounted about a common axis. The bearing pin 40 receives a coupling pawl 42. The coupling pawl 42 has the shape of a circular arc section. As in coupled state in FIG. 6 can be seen, the outer contour of the coupling pawl 42 forms with the two nut halves 22, 24 a circular outer contour.

The coupling pawl 42 forms a coupling bar 43 parallel to the common axis of the coupling halves 22, 24. The coupling bar 43 is the shape of the holding table 41 adapted in shape. The holding table 4 is arranged so that it lies in the displacement path of the coupling bar 43. In the assembled state of the multi-part nut 7 is for example in the FIGS. 7 and 8th Good to see that the coupling bar 43 after pivoting the upper half nut 22 with the retracting lever 23 and the second half nut 24 can rotate with each other. The coupling pawl 42 forms a step portion 44. The circular arc surface of the stepped portion 44 and the outermost circular arc surface of the retraction lever each form a control cam 45, 46. As in the FIGS. 1 to 4 and FIG. 11 can be clearly seen, the clutch pawl 42 is acted upon in the uncoupled position by a leg torsion spring 47. The leg torsion spring 47 is arranged around a pin 48, which extends from the lock bottom 4. The pin 48 forms, as well as the fixing pin 12, a threaded bore 13. In this also a fixing screw can be screwed to fix the lock cover on the lock bottom 4.

In FIG. 11 It is good to see that the multipiece nut 7 is held in the neutral position by two pusher nut springs 49, 49 '. The pusher core springs 49, 49 'are arranged parallel to one another in the axial direction of the multi-part pusher nut 7. The pusher nut springs 49, 49 'each receive a plunger 50, 50'. By the two pusher springs 49, 49 'with the two plungers 50, 50', the two nut halves 22, 24 are cushioned separately from each other. The pusher core springs 49, 49 'and the plungers 50, 50' are each in a receiving shaft 51 in the receiving body 5 a. The two receiving wells 51 are spatially separated. The plungers 50, 50 'each form a collar 52, 52'. The receiving wells 51 are designed such that they respectively receive the pusher nut springs 49, 49 'and the collar 52, 52' of the ram 50, 50 '. The collars 52, 52 'in each case form a stop, which prevents too great an emergence from the receiving slots 51.

In order to couple the shaft screw 36 with the first nut half 22 or with the second nut half 24 and the return lever 23, a bore is provided in the lock bottom 4 and in the lock cover. This hole is slightly larger than the largest diameter of the shaft screw 36 configured. Through the hole you can, for example, with a suitable screwdriver unscrew the shaft screw 36 from the retraction lever 23 and, if necessary, screw it in again from the other side of the retraction lever 23. It is therefore not necessary to disassemble the lock 1 in order to exchange the coupling with the retraction lever 23 of the two nut halves 22, 24.

Arranged behind the faceplate 3 on the lock bottom 4, the espagnolette gate valve 8 runs. Parallel to the case 6, the bolt 9 runs in the FIGS. 12 to 16 the espagnolette slide 8 and the latch 9 are shown. The espagnolette 8 has on its underside in the direction of the lock bottom. 4 not shown here pin. These pins engage in slots of the lock bottom 4. As a result, the espagnolette 8 is slotted. The slot pin guide allows the espagnolette slide 8 only a displacement in the longitudinal direction of the faceplate 3. At the end of the espagnolette 8, which is disposed below the bolt 9, this forms a drive ridge 53 from. This concludes flush with the upper broad side of the bolt 9. The espagnolette 8 has a removable control pin 55 located on a web 54. These are arranged above the bolt 9. The espagnolette slide 8 forms a control slot 56 (see FIG. 13 ). The control slot 56 extends diagonally to the Stulperstreckungsrichtung the faceplate 3. At its two ends, the control slot 56 each have a niche 57, 57 'on. The niches 57,57 'extend in the direction of displacement of the espagnolette slide 8. At one end of the espagnolette 8 this forms a blocking arm 58 from. The blocking arm 58 has a bevel 59 at the bottom. At this slope 59 may optionally slide off the back of the case 6.

The web 54 extends obliquely in the direction of the bolt 9. On the surface which faces the latch 9, the web 54 forms an engagement surface 60 for the slide displacement arm 39. Between the removable control pin 55 and the drive ridge 53 of the drive rod connecting slide 8 forms a stop pin 61. The stop pin 61 forms above a smaller diameter portion 62.

Furthermore, as in FIG. 16 can be seen, the espagnolette 8 forms on the side facing away from the faceplate 3 two detent pockets 63 and 64. The bolt 9 extends transversely to the displacement direction of the espagnolette slide 8. This forms at its lower broad side, which is turned to the espagnolette 8 back, a pin 65 from. The pin 65 protrudes into the control slot 56. As in the Figures 12 and 15 can be seen well, forms the latch 9 on the side facing the stop pin 61, a corresponding niche 66 from. In FIG. 12 It can be seen that the stop pin 61 has been displaced into the niche 66. In the direction of displacement of the espagnolette 8, a pocket 67 is incorporated into the latch 9 centrally of the niche 66. The pocket 67 extends approximately to the middle of the bar 9. It is about 2 mm deep from the surface. Below the pocket 67 in bolt displacement direction extends a shaft 68th

The shaft 68 extends from the pocket 67 to the latch end surface 69. The pocket 67 and the shaft 68 overlap and form a common space in their cutting area. In the shaft 68 is an elongated button 70 a. The button 70 is the length and the Shape of the shaft 68 adapted. At the inserted end of the button 70 this forms at its end a diagonal slot 71. In this slot, a pin 72 of a release slide 73 protrudes.

The release slider 73 is adapted to the shape of the pocket 67, but this is designed somewhat shorter in shape. The latch 9 forms at its end at its upper broad side a pin 74. The pin 74 forms a smaller diameter portion 75. Furthermore, the latch 9 forms a recess 76 at its upper broad side. In the recess 76 is a locking slide 77 a. At its upper broad side of the locking slide 77 forms a locking cam 78. The side of the locking slide 77, which points to the locking end face 69 of the bolt 9, forms a central mandrel 79. The mandrel 79 receives a compression spring, not shown here in the drawings. The compression spring acts on the locking slide 77 in the direction of the pin 74.

The portion 75 of the pin 74 engages in a slot which extends in latch displacement direction and is located in the lock cover. This serves to guide the bolt. 9

As in the FIGS. 1 to 4 can be seen, the receiving body 5 is arranged below the pin 48, a latch 80 from. The latch 80 is the shape of the latching pockets 63, 64 form-matched. The latch 80 is received by the receiving body 5. This is spring-loaded by a compression spring, not shown here in the direction of the faceplate 3. The espagnolette 8 is held by the latch 80 in the respective position.

Parallel to the espagnolette 8, above the bolt 9, an auxiliary slide 81 is arranged. The auxiliary slide 81 partially overlaps the latch 9 in the closed-back state. The auxiliary slider 81 forms in the direction of longitudinal extension of the faceplate 3 in the direction of the multi-part nut 7 a guide web 82. In the guide web 82, a slot 83 is arranged. This extends in the direction of displacement of the espagnolette slide 8. In this slot 83, the portion 62 of the stop pin 61 projects into it. The guide bar 82 merges into a narrower actuating bar 84. This has at its end a square floor plan. In the area that overlies the latch 9, the auxiliary slide 81 forms a running in bolt displacement direction open-edged slot 85. The slot 85 has on its lower side a ramp be 86. The slot 85 is conformed to the shape of the pin 74 of the latch 9. Below the slot 85, an opening 87 is arranged. The opening 87 has a similar shape as the slot 85 with the run-on slope 86. Also, the opening 87 forms a run-on slope 88. In the parallel to the faceplate 3 extending Wall of the opening 87, this forms an upper detent niche 89 and a lower detent 90 from. The upper detent niche 89 and the lower detent niche 90 as well as the front slot-like region are adapted to the detent cam 78 of the detent slide 77. In extension of the guide web 82 in the direction of the lock cylinder 10, the auxiliary slide 81 forms an attack ridge 91.

To the lock cylinder 10, two superposed annular section-shaped rotation transmission members are arranged, which are each formed by a curved piece 92, 93. The bow pieces 92, 93 are good in the FIGS. 17 and 18 to see. The two curved pieces 92, 93 close approximately at an angle of 225 deg. one. The elbow 92 forms on its upper broad side two elongated pins 94. The elongated pins 94 are adapted to the shape of the sheet curve. As in FIG. 18 can be seen, the elbow 92 also forms on the bottom of two further elongated pin 95. The elongated pins 94, 95 are arranged in parallel one above the other and have the same angular distance from one another. In the FIGS. 17 and 18 towards the left side, the elbow 92 forms an arm 96. The arm 96 is designed such that it can engage in each rotational position optimally from below on the drive ridge 53 of the espagnolette 8 slide. The elbow 92 is responsible for the displacement of the espagnolette 8 in the direction of the multipiece nut 7.

The elbow 93 forms at its upper broad side a circumferential annular groove 97. The circumferential annular groove 97 is the shape of the elongated pin 95 form-matched. In parallel superimposition of the two curved pieces 92, 93 engage the elongated pin 95 in the circumferential annular groove 97 a. The circumferential annular groove 97 ensures that the two curved pieces 92, 93 can move independently of each other, thus each curved piece 92, 93 can assume a different angular position. As in FIG. 18 can be seen, the elbow 93 also forms on its underside elongated pin 98. The elongated pins 94 of the arcuate piece 92 and the elongated pins 98 of the arcuate piece 93 each engage in arcuate slots in the lock cover or in the lock bottom 4. The arcuate slot 99 in the lock bottom 4 is in the FIGS. 2 to 4 to see. The arcuate slot 99 is conformed to the shape of the elongate pins 98. The elbow 93 also forms an arm 100. The arm 100 is displaced parallel to the arm 96 of the elbow 92. The arm 100 protrudes tangentially from the elbow 93. The arm 100 also engages the drive ridge 53 of the espagnolette 8. However, the arm 100 engages the drive ridge 53 from above. The arm 100 is responsible for the displacement of the espagnolette 8 in the direction of the lock cylinder 10. The two curved pieces 92, 93 each form a stop shoulder 101 and one of the opposite counter-stop shoulder 102. The counter-attack shoulder 102 is near the two arms 96, 100. At the stop shoulder 101 and the counter stop shoulder 102, a closing member 103 can attack. The angle between the two stops 101, 102 is dimensioned so that even with the key removed, the two curved pieces 92, 93 can shift back to their original position of movement.

The closing member 103 is connected in a known manner with the lock cylinder 10. The lock cylinder 10 is received by a forend screw 104 in the lock housing 2 fixing.

• In Figur 1 ist das Schloss 1 mit einem vorgeschlossenen Riegel 9 dargestellt. Der Riegel 9 wird mit Hilfe eines passenden Schlüssels, der in den Schliesszylinder 10 eingesteckt wird, vorgeschlossen. Durch Drehen des passenden Schlüssels gegen den Uhrzeigersinn, greift dann das Schliessglied 103 gegen die Anschlagschulter 101 der beiden Bogenstücke 92, 93. Beide Bogenstücke 92, 93 oder zumindest das Bogenstück 93 werden gegen den Uhrzeigersinn verlagert. Der Arm 100 des Bogenstücks 93 greift von oben an dem Antriebssteg 53 an und verlagert dadurch den Treibstangenanschlussschieber 8 in Richtung des Schliesszylinders 10. Durch die Verlagerung des Treibstangenanschlussschiebers 8 verlagert sich der Riegel 9 gehäuseauswärts. Dieses wird durch eine Schlitz-Zapfensteuerung erreicht (Figuren 13,14 und 16). Zuerst befindet sich der Zapfen 65 des Riegels 9 in der Nische 57 des Steuerschlitzes 56. Nach einer gewissen Verlagerung des Treibstangenanschlussschiebers 8 in Richtung des Schliesszylinders 10 gelangt der Zapfen 65 aus der Nische 57 heraus und wird von dem Steuerschlitz 56 gehäuseauswärts verlagert. Nachdem der Riegel 9 komplett gehäuseauswärts verlagert worden ist, verlagert sich der Treibstangenabschlussschieber 8 noch ein Stückchen weiter in Richtung des Schliesszylinders 10, so dass der Zapfen 65 des Riegels 9 von der Nische 57' eingefangen wird. Durch die Verlagerung des Treibstangenanschlussschiebers 8 verlagert sich ebenfalls auch der darauf angeordnete Anschlagzapfen 61 in Richtung des Riegels 9. Der Anschlagzapfen 61 stösst bei der Verlagerung des Treibstangenanschlussschiebers 8 gegen den Freigabeschieber 73. Der Freigabeschieber 73 wird in Richtung des Schliesszylinders 10 verlagert. Durch Verlagerung des Freigabeschiebers 73 verlagert sich der Taster 70 derart, dass dieser aus der Riegelstirnfläche 69 herausragt. Der Taster 70 wird durch den Freigabeschieber 73 verlagert, weil die beiden über eine Schlitz-Zapfenführung miteinander verbunden sind. Der Zapfen 72 des Freigabeschiebers 73 greift in den Schlitz 71 des Tasters 70 hinein. Der Treibstangenanschlussschieber 8 wird durch die Rastklinke 80 in seiner Position fixiert. Die Rastklinke 80 greift in die Rasttasche 63 ein. Durch die Schliessbetätigung des Schliesszylinders 10 wird der Treibstangenanschlussschieber 8 derart beaufschlagt, dass die Rast zwischen der Rastklinke 80 und der jeweiligen Rasttasche 63, 64 aufgehoben wird. Mit der Verlagerung des Treibstangenanschlussschiebers 8 wird auch der Hilfsschieber 81 in Richtung des Schliesszylinders 10 verlagert. Beim Vorschliessen des Riegels 9 gleitet der Rastnocken 78 auf der Auflaufschräge 88 ab und verlagert somit den Hilfsschieber 81. Bei komplett vorgeschlossenem Riegel 9 liegt der Zapfen 74 in dem Schlitz 85 ein.

The operation of the lock 1 is described in more detail in the following text:

• In FIG. 1 the lock 1 is shown with a locked bolt 9. The bolt 9 is prefixed by means of a suitable key, which is inserted into the lock cylinder 10. By turning the appropriate key counterclockwise, then the closing member 103 engages against the stop shoulder 101 of the two curved pieces 92, 93. Both curved pieces 92, 93 or at least the curved piece 93 are displaced counterclockwise. The arm 100 of the elbow 93 engages from above on the drive ridge 53 and thereby displaces the espagnolette slide 8 in the direction of the lock cylinder 10. By the displacement of the espagnolette 8, the latch 9 displaces out of the housing. This is achieved by a slot-pin control ( Figures 13 . 14 and 16 ). First, the pin 65 of the bolt 9 is in the niche 57 of the control slot 56. After a certain displacement of the espagnolette 8 in the direction of the lock cylinder 10, the pin 65 passes out of the recess 57 and is displaced from the control slot 56 housing outward. After the latch 9 has been displaced completely outward of the housing, the drive rod closing slide 8 moves a little further in the direction of the lock cylinder 10, so that the pin 65 of the lock 9 is captured by the niche 57 '. The displacement of the espagnolette 8 also displaces the abutment pin 61 disposed thereon in the direction of the bolt 9. The abutment pin 61 abuts against the release slider 73 when the espagnolette gate 8 is displaced. The release slider 73 is displaced in the direction of the closing cylinder 10. By displacement of the release slide 73, the pushbutton 70 displaces in such a way that it protrudes from the locking face 69. The button 70 is displaced by the release slide 73, because the two are connected to each other via a slot-pin guide. The pin 72 of the release slide 73 engages in the slot 71 of the button 70 inside. The espagnolette 8 is fixed in position by the detent pawl 80. The detent pawl 80 engages in the latching pocket 63. By the closing operation of the lock cylinder 10 of the espagnolette slide 8 is acted upon such that the Rest between the latch 80 and the respective latching pocket 63, 64 is repealed. With the displacement of the espagnolette 8 also the auxiliary slide 81 is displaced in the direction of the lock cylinder 10. When Vorschliessen the bolt 9 of the locking cam 78 slides on the ramp 18 and thus displaces the auxiliary slide 81. When completely locked latch 9, the pin 74 is in the slot 85 a.

As in FIG. 1 can be seen, the clutch pawl 42 is in the uncoupled position. The clutch pawl 42 has been pivoted by the force of the leg torsion spring 47 counterclockwise. As a stop for the coupling pawl 42, the web 54 of the espagnolette gate valve 8. The coupling pawl 42 abuts with its coupling bar 43 against the web 54. The actuating web 84 of the auxiliary slide 81 is located with its front tip on the step portion 44 of the coupling pawl 42. The espagnolette 8 is displaced so far in the direction of the cylinder lock 10, so that the blocking arm 58 is in the displacement path of the case 6 itself. Due to the blocking arm 58, it is not possible for the trap 6 to shift towards the housing.

The slider displacement arm 39 of the retraction lever 23 bears against the inclined surface 60 of the web 54. The first nut half 22 is by means of the shaft screw 36 which has been screwed into the retraction lever 23, rotatably coupled thereto. In the first half of the nut 22 is an unillustrated half-dowel of a door inner handle, not shown. In the second nut half 24 is an unillustrated Türaussendrücker. If you start from FIG. 1 actuates the Türaussendrücker, only the second half nut 24 would rotate clockwise and drive with its stopper 31 against the lower plunger 50 'and this shift against the force of the follower key spring 49' in the direction of the lock cylinder 10. This is in FIG. 11 illustrated. But if now the inside door handle is actuated, which is inserted in the square recess 25 of the first half nut 22 and this is permanently coupled to the retraction lever 23, the Schieberverlagerungsarm 39 would be displaced against the inclined surface 60 of the web 54 of the espagnolette 8 and this in the direction of the trap 6 relocate. After a certain displacement path of the espagnolette 8, the latch retraction arm 38 also engages the actuating portion 17 of the square body 16. By further turning the first nut half 22 with the coupled retraction lever 23, the latch 6 moves inwardly against the force of the latch spring 18. However, this is only possible if the espagnolette 8 has displaced so far that the blocking arm 58 of the espagnolette 8 slides out has moved the displacement path of the case 6 addition. With the displacement of the espagnolette 8, the niche 57 'releases the pin 65 of the latch 9 and this is then displaced through the control slot 56 housing inward. After the bolt 9 has been displaced completely inwardly of the housing, the espagnolette gate 8 moves further towards the split nut 7. It displaces so far that the pin 65 is caught by the recess 57. By the return movement of the bolt 9 also displaces the locking cam 78 of the locking slide 77 in the upper detent niche 89. By the compression spring, not shown, the locking slide 77 is acted upon by the locking cam 78 in the direction of the detent niche 89. The locking slide 77 fixed by means of the locking cam 78, the auxiliary slide 81 in its lower position. The position of the auxiliary slider 81 is with the position of the auxiliary slider 81 in the FIG. 3 to compare. In the FIG. 1 is the espagnolette 8 seen as a coupling slide. The espagnolette 8 is considered as a coupling slide, because it moves with its control pin 55 against the cam 46 of the clutch pawl 42 and this pivoted about the bearing pin 40 in the clockwise direction such that the coupling bar 43, the two nut halves 22, 24 and the retracting lever 23 couples together. Now it is possible to open a door with a lock according to the invention both with the door inner handle and with the outer door handle and move the case 6 housing inward.

Furthermore, there is the possibility to move the latch 9 housing inwards by inserting a matching key in the lock cylinder 10 and the closing member 103 pivoted clockwise that this pushes against the counter-stop shoulder 102 and the two curved pieces 92, 93 displaced clockwise. Along with the displacement of the two curved pieces 92, 93, the driving rod connecting slide 8 is also displaced in the direction of the case 6. The bolt 9 behaves as described above. This also shifts towards the housing. However, the auxiliary slider 81 is displaced by the arm 96 in the direction of the case 6, so that the locking cam 78 of the locking slide 77 rests in the lower latching niche 90. The locking slide 77 fixes the auxiliary slider 81 by the spring load in this position.

Another way to move the bolt inward, provides a device provided in the passive leaf, which displaces the latch 9 and the case 6 housing inward by operating a lever. This device first presses the button 70 into the latch 9 until it is flush with the latch end face 69. By pressing the button 70, the release slider 73 moves in the direction of the case 6 and presses against the stop pin 61 of the espagnolette 8 and moves it far enough that the pin 65 of the bolt 9 is displaced out of the niche 57 '. By further relocating the bolt 9, the pin 65 controls against the control slot 56 and further displaces the espagnolette 8 in the direction of the latch 6. After the espagnolette 8 has been displaced so far that the locking arm 58 has emerged from the displacement path of the latch 6 can the device the trap 6 shift inward. The auxiliary slider 81 is not displaced in the direction of the case 6. This is possible because the two curved pieces 92, 93 can assume a different angular position to each other. The elbow 93 is pivoted by the espagnolette 8. This happens because the arm 100 abuts the drive ridge 53 from above. The elbow 92 can be taken as far from the elbow 93 until the elbow 92 abuts against the attack bar 91. The entrainment of the elbow 92 could only be caused by frictional engagement. The clutch pawl 42 is displaced by the espagnolette 8 with its control pin 55 in the coupled position. Thus, the door can be opened from the inside both from the outside.

If you want that after such an opening only the lock 1 can continue to be opened with the inner door handle, so you have to remove the control pin 55 at the espagnolette gate valve 8, which was previously considered as a coupling slide. Thus, the auxiliary slider 81 becomes the coupling slider. Unlike the FIG. 3 is seen in the FIG. 4a after the depressed latch 9, the clutch pawl 42 is in the decoupled state. In order to move the clutch pawl 42 in the coupled state, you need a matching key for the lock cylinder 10. To couple the two nut halves 22,24 with the retracting lever 23, you have to shift the appropriate key clockwise so that the closing member 103 against the counter-abutment shoulder 102 abuts and displace the offset elbow 92 into a congruent position with the elbow 93. Since the arm 96 of the elbow 92 rests against the engagement bar 91, the auxiliary slider 81 is displaced in the direction of the trap 6 along with the displacement of the arched piece 92. The auxiliary slide 81 then abuts with its actuating bar 84 against the stepped control cam 45 of the step portion 44 and displaces the coupling pawl 42 in the coupled position. In the variant that in FIG. 4a an intentional coupling of the two nut halves 22, 24 is provided. In the previously described FIGS. 1 to 3 the two nut halves 22, 24 are coupled with the second nut half 24 when closing the bolt 9, and when pushing back the bolt 9 and when operating the nut half 22 (which is permanently coupled to the retraction lever 23).

While at the in the FIG. 4a illustrated variant of the auxiliary slide 81 according to the locking cam 78 remains in its coupling position, when the auxiliary slide 81 is lifted before the elbow cylinder 92 actuated by closing, are in the in FIG. 4b variant shown no locking means provided. If the locking cylinder 81 is swung back into the coupling position after displacement of the auxiliary slide 81, the auxiliary slide 81 also moves out of the coupling position. This can be done either by the force of gravity or by the force of a spring, not shown. It is essential that at this in FIG. 4b illustrated embodiment, the Aussendrückerbetätigung is only possible if the lock cylinder 10 is operated simultaneously. If a door equipped in this way is to be actuated from the outside, this is only possible if a key is inserted into the lock cylinder 10 from the outside and this is turned in the opening direction. If the key is removed again, the trigger external actuation is deactivated.

The FIG. 19 shows the two bow pieces 92, 93 in their respective rotational end position. It can be seen that the stop flanks 101 and 102 occupy a minimum angle between them. This angle can be between 45 deg. and 90 deg. lie. It preferably corresponds to 60 °. It corresponds to the position of the closing element 103 in the key withdrawal position, depending on whether the closing element 103 is located on the left or right of the profile section of the closing cylinder 10.

The FIGS. 20 to 22 show further possible embodiments of a lock 1, which are shown in the pre-closed position. Identically designed or acting components are provided with the same reference numerals that have been previously used in the previous versions.

Below are the deviations of the in FIG. 20 illustrated embodiment of the embodiment in FIG. 1 explained. The espagnolette 8 has no more control pin and no longer serves as a coupling slide. In this embodiment, the coupling pawl 42 is also designed arcuate, but the coupling pawl 42 is pivotally mounted on Fallenrückzugsarm 38 of the retraction lever 23. In this embodiment, the coupling pawl 42 is no longer stepped. Approximately in the longitudinal direction of the center of the coupling pawl 42 is also a coupling bar 43 is formed as in the embodiments described above, which extends in the direction of the spacing of the lock bottom 4 and lock cover. The coupling bar 43 is also adapted to the holding table 41. Also, the coupling pawl 42 is acted upon by a leg torsion spring 47 such that the coupling pawl 42 is acted upon in the direction of the uncoupled position.

The mode of action of the execution in FIG. 20 is with the operation of the execution FIG. 4a to compare.

The execution, in the FIG. 21 is shown in relation to the embodiment in FIG. 20 explained in more detail. The lock has no locking slide. Furthermore, the slot 83, which is located in the guide web 82 of the auxiliary slide 81, designed to be shorter than in the embodiments described above. The length of the slot 83 is selected so that at a always located in the lock housing 2 latch 9 always the auxiliary slide 81, the coupling pawl 42 applied such that it couples the two nut halves 22, 24 with each other. When relocating the latch 9 into the lock housing 2, the drive rod connection slide 8 is always displaced in the direction of the latch 6. Along with the displacement of the espagnolette 8, the portion 62 of the stopper 61 disposed on the espagnolette 8 also shifts towards the case 6. The portion 62 abuts against the wall thereof during the displacement of the espagnolette 8 in the upper end portion of the slot 83 and thus displaces the auxiliary slider 81 also in this direction. The auxiliary slide 81 is displaced so far in the direction of the case 6, until it acts on the coupling pawl 42 such that the coupling bar 43 rests in the holding arms 41 of the two nut halves 22, 24 and couples these together. Due to the shorter configuration of the slot 83, the two nut halves 22, 24 are coupled with each other when the bolt 9 is retracted into the lock housing 2. The lock 1 can then be operated both with the inner and with the outer handle.

At the in FIG. 22 shown lock is different from the execution in FIG. 20 no locking slide 77 is provided. Furthermore, the auxiliary slider 84 forms an actuating web 84, which extends transversely to the longitudinal extension of the auxiliary slide 81. The actuating web 84 is rounded in the direction of the split nut 7. Due to the rounded configuration of the actuation web 84, during the displacement of the auxiliary slide 81 in the direction of the catch 6, it always lies approximately at the same area on the coupling pawl 42. In this embodiment, the actuating web 84 engages in the lower end region of the coupling pawl 42.

The mode of action of the execution in FIG. 22 is with the previously described operation of the embodiment in the FIG. 4b to compare.

In the in the FIGS. 21 to 22 illustrated embodiments, the coupling slide 81 engages the lever-mechanically most favorable portion of the coupling pawl 42 to relocate the latter. The slider engages the long lever arm to move the spaced apart with a shorter lever arm to the fulcrum coupling bar 43 in its associated holding tables, so that the two nut halves are drehgekuppelt each other.

The following features are considered to be particularly advantageous. The slider 8 is displaceable by turning the nut half 22, which is permanently coupled with the retraction lever 23, into its coupling position. The clutch pawl 42 is exclusively by Lock cylinder actuation in the coupling position displaced. The coupling pawl spring is mounted on the lock housing 2. The coupling pawl spring is a leg torsion spring 47, which is mounted around a housing-fixed pin. There is a slide displacement arm 39 is provided which is associated with the return lever 23 and engages the slider 8. The coupling slide is displaceable by the lockable by pressure on its end face 69 9 bars. The auxiliary slider 81 is held by a latch 77 in a coupling position corresponding displacement position. The coupling pawl 42 is mounted on the Fallenrückzugsarm 38 of the retracting lever 23. The slider 8 is guided transversely to the bolt displacement direction in the lock housing 2 and drives the bolt 9 via a slot-pin control. The rotational release of the closing member (103) is in a position of the two curved pieces 92, 93, in which the arms 96, 100 each occupy their initial movement position, about 45 °. up to 90 deg. , preferably about 60 °. The slider 8 is a coupling slider for rotatably coupling a nut half 24 to a retracting lever 23. The auxiliary slide 81 is latched by a bolt 9 associated locking cam 78 in one of its two Schubendstellungen detent. The oblique slot 56 is associated with the slider and the pin 65 engaging therein the latch 9. The release slider 73 cooperates with the button 70 via a slot-pin control. The button 70 is displaced by urging the slider 8 through the stop pin 61 in the forward position. The slide is a espagnolette slide 8. The espagnolette slide 8 is held by a detent pawl 80 in its locked position.
