Description

LOCK. IN PARTICULAR LOCKED LOCK FOR A DOOR FIELD OF THE INVENTION The present invention relates to a lock, and in particular to a recessed lock for an external door. The door has a latch bolt and an additional latch located displaceably, parallel to each other, in a housing, wherein the additional latch can be operated by means of a key and / or a rotary knob, and the latch bolt can be operated selectively by means of a latch with a follower, or by means of a key or by means of a rotary knob.

BACKGROUND OF THE INVENTION From the German patent publication DE 92 08 526 Ul a lock for an external door is known. This known lock has a latch bolt which can be retracted in the lock housing by means of a follower on which the bolt is held. An additional latch is located below the latch bolt, which can be opened from the lock housing by means of a profiled cylinder. In addition, the profile cylinder can be pulled into the latch bolt by means of a changer. Such a lock was developed for the German or European market. The American locks have the peculiarity that, as a rule, the latch with the latch and latch bolt are arranged in the lower part, and the additional bolt is located in the upper part in the lock housing. In addition, as a rule, the additional latch operates by means of a key on one side and a rotary knob on the other side. Such locks have properties which are comparable with the locks mentioned at the beginning. However, it is not possible to couple such connection bars with such locks, by means of which the supplementary lock boxes, or respectively, the supplementary latches are joined, through which the strength of the anti-buckling door could be increased.

OBJECTIVES AND SUMMARY OF THE INVENTION Therefore, an objective of the present invention is to provide a lock mentioned at the beginning that satisfies the requirements of the North American market and that can be used in the same way as the North American locks, and that can be taken position of as many components as possible, or that, respectively, only minor changes need to be made.

This objective is achieved in accordance with the present invention wherein the additional latch is connected by means of a two-armed articulated lever with a turning element operated by the key or the rotary knob, wherein an arm of the articulated lever engages pivotally with the turning element, and the other arm is pivotally coupled with the additional latch, and wherein the two arms are pivotally connected to each other with their free ends, wherein an arm is rotatably mounted and, if required, displaced between its ends in a fixed bearing in place in the housing. By means of this modality, in accordance with the present invention, a lock is made available for the North American market which is based on the characteristics of the European recessed lock. Therefore, it is possible to use a lock having a known lock housing, which is recognized, for example, from the German patent publication DE 92 08 526 Ul. This lock is only rotated, so that the latch bolt is in the lower part and the additional latch in the upper part. In order to obtain a correct direction of rotation to rotate the additional latch forward, that is, to extend it, with this tumbling lock, an inversion of the direction of rotation is generated by means of an articulated lever. The key, or respectively the rotary knob, drive the first articulated arm of the articulated lever, which is pivotably fastened to the rotating element and can be rotated about a fixed axis in place in the housing. In this way, an inversion of the direction of rotation is generated, which is transferred by the other end of this pivot arm to a second pivot arm, which acts on the additional bolt and extends outside the lock housing. With the lock according to the present invention, the additional latch extends so that the turning element is rotated either by the lock or by the rotary knob in the conventional direction, ie, where the upper half of the key, or respectively the rotary knob are rotated in the closed direction. Such a recessed lock can also be connected with a connecting rod. The advantages, features and additional details of the present invention are presented from the following description, wherein the various exemplary embodiments are described in detail, with reference to the drawings. The features depicted in the drawings as well as in the specification may be essential for the present invention both individually per se and in any arbitrary combination.

DESCRIPTION G ^ AT, T.A? OF THE PREFERRED MODALITIES Figure 1 shows a lock housing, identified in its entirety with the number 1 and with the cover removed. A latch bolt 2 and an additional bolt 3 inside the housing can be displaced in the direction of the double-ended arrow 4. In addition, a follower is placed, which can rotate in the direction of the double-ended arrow 6 in the lock housing 1. The follower 5 has an opening 7, in particular a square opening, for receiving a square pin from a bolt or a similar actuation element. A projection 8, radially extending from the follower 5 is located below a projection 9 of the arm 10 of the latch bolt, by means of which the bolt can be turned back. In addition, the follower 5 has a partial gear ring 11, which engages with a toothed rack 12, which is held in its rest position shown in Figure 1 by means of a reset spring, not shown, located in a spring housing 13. The toothed rack 12 can move in both directions from its rest position. For the. both, the follower 5 is rotated in the direction of the arrow 14, this causes compression of the reset spring on one side and, on the other hand, the projection 8 begins to bear against the projection 9 of the arm 10 of the latch bolt and it rotates the latter in a clockwise direction around a bearing 15. By this action, the actuating arm 16 moves and engages with the projection 17 of the tail 18 of a bolt of latch. This causes the latch bolt 2 to rotate back inside the bolt housing 1 in the direction of the arrow 19. The extension of the bolt bolt 2 after the bolt has been released and after the reset of the follower 5 by means of the replacement spring, not shown, is aided by a torsion spring 20 which is supported on one side of the bolt housing 1, and acts on the projection 17 with the other leg and pushes the bolt 2 out of the housing 1 of the bolt. bolt. In this case, the extension movement is approximately 10 mm. In addition, a turning element 21 is rotatably housed in the lock housing 1, wherein the turning element 21 is provided with a groove 22. A corresponding wedge of a rotating knob engages with this groove 22 on one side, for example, and on the other side a corresponding wedge of a cylinder, which can be operated by means of a key. In this case, the turning element 21 is designed in such a way that it can be installed in already existing recesses, inside which a cylinder profile can be inserted. A first arm 23 of an articulated lever 24 is fastened, pivotably around a bolt 25, in the turning element 21. In addition, the first arm 23 has an elongated hole 26, which is engaged by means of a pin 27 fixed in place on the housing. On the side opposite the latch 25, the first arm 23 is pivotably connected by means of a pivot bearing 28 or in a second arm 29, wherein the second arm 29 acts on the latch tail 31 of the additional latch 3 by means of a latch 30. A torsion spring 32 is housed around the bolt 30 and is supported by its leg 33 in a receptacle 34 of the additional bolt 3, although with its other leg 35 it extends around the pivot bearing 28. The torsion spring 32 is positioned such that the pivot bearing 28 is urged around the latch 30 in a clockwise direction. The lock according to a first exemplary embodiment shown in Figure 1 has the important advantage that, in the manner of the North American locks, it has a latch bolt 2 in the lower part and an additional bolt 3 in the upper part, in where the additional latch 3 can be moved forward outside the key housing by actuation of the turning element 21 by means of a key or by means of a rotary knob in a clockwise direction (in the position) represented). In this case, the extension is approximately 25 mm. The forward displacement of the additional bolt 3 by rotating the turning element 21 in a clockwise direction occurs so that the course of rotation of the turning element 21, the first arm 23 is taken together with the latch 25 is rotated in a counter clockwise direction around the pin 27, and furthermore it moves in the direction towards the elongated hole 26. This causes the second arm 29 to move essentially in the extension direction of the additional latch 3 (to the right). In addition, the latch or pivot bearing 28 performs an arc-shaped movement suggested by discontinuous line 36. On its oriented side away from the observer, the pivot bearing 28 has an axial projection which, in the position of the articulated lever 24 shown in Figure 1, extends behind a projection 37 fixed in place on the housing. In this way the displacement of the additional latch 3 is prevented outside the bolt housing 1, without the actuation of the rotary element 21. In the end position of the pivot bearing 28 with the extended additional latch 3, not shown in Fig. 1, the axial projection of the pivot bearing 28 is located behind a second projection 38 fixed in place on the housing, by means of from which it is carried out so that the extended additional latch 3 can not be pushed back into the lock housing 1, without rotating the rotary element 21. Figure 2 depicts a second exemplary embodiment 5 of the lock according to the present invention, wherein similar components are identified with the same reference numerals. In this exemplary embodiment, a connecting rod plate 39 is placed in the lock housing 1 and can be moved in the direction of the double-ended arrow 40. The bars 43 are connected at points 41 and 42 to this busbar plate 39. These connection bars 43 are located behind the cover rails 44 which, in the installed position of the lock 1, terminate and cover it on the visible side. In Figure 2, a rotary slider 45 is rotatably attached to the follower 5. If the follower 5 is activated, the rotary slider 45 is carried with it, which will be further explained later. The rotary slider 45 has a bolt 46, which makes contact with an elongated hole 47 in the plate 39 connection bar. The rotary slider 45 further has a curved elongated hole 48, by means of which the bearing 15 is deflected. Therefore, if the follower 5 moves in an anti-clockwise direction, for example, the projection 9 of the arm 10 of the latch bolt is carried along the projection 8 and moves around the bearing 15 in a clockwise direction, as a result of which the latch bolt 2 is pushed into the housing 1 of lock. In addition, the rotary slider 45 is pivoted by the rotary movement of the follower 4 and the bolt 46 is moved upwards, as a result of which the plate 39 of the connecting rod also moves upwards. In this way, the connecting bars 43 are pushed upwards. In Figure 3 an additional lock 49 is shown, where the cover has also been removed. The additional lock 49 is connected to the lock housing 1 of the built-in lock by means of the connecting bar 43. A latch bolt 50 is positioned, movable in the direction of the double-ended arrow 51, in the additional lock 49. In the shown representation, this latch bolt 50 is in its forward rotated position. The latch bolt 50 has a latch bolt tail 52 that includes a projection 53. Furthermore, it is possible to observe in FIG. 3 that the latch bolt retaining lever 55 is pivotably housed around a bearing bolt 54 and has a spring loaded in a clockwise direction by means of a retainer lever spring 56 included as a torsion spring. If the latch bolt 50 is in its fully extended position, that is, in the closed position, an edge 57 of the latch retainer extends around the projection 53. Although there may be a small space between the projection 53 and the edge 57 of the latch retainer, as shown in FIG. 3, the latch retainer edge 57 extends into the displacement view of the projection 53, so that the latch bolt 50 can not be easily inserted into the housing of the additional lock 49. Therefore, in its closed position, the latch bolt 50 is immobilized preventing unauthorized insertion. If a bolt reset lever 58, which is supported by an arm 59 against the free end of the connecting rod 43, and with its other arm 60 against an additional projection 61 of the tail 52 of the latch bolt, is rotated by means of the connecting bar 43, a projection 62 of the free arm 60 engages a crank 63 of the catch lever 55 of the latch bolt and is lifted sufficiently out of its closed position in which the edge 57 of the latch detent extends behind the projection 53, so that the latch retainer edge 57 moves out of the displacement track of the projection 53. In addition, the arm 60 bears against the projection 61, and in FIG. the course of the rotation of the bolt reset lever 58 pulls the latch bolt 50 into the additional bolt 49. The extension of the latch bolt 50 takes place by means of the bolt extension lever 64, which is housed in the bearing 65 and is urged in a counterclockwise direction around the bearing 65 by the spring 66 of bolt extension. With its free end, the lock extension lever 64 acts on the latch bolt 50 and attempts to move it out of the additional bolt 49. Now, if the follower 5 (Figure 2) moves in the closed position (rotated in a clockwise direction), the latch bolt 50 of the supplementary bolt 49 is rotated forward. Since the projection 8, by means of which the rotary slider 45 is carried with it, moves on a curved edge 67, the rotary slider 45, and therefore also the connecting rod plate 39, remain in the position flexed when the follower 5 is restored to its initial position, represented in figure 2, by means of the resetting spring. The latch bolt 50 in this manner remains extended. If the follower 5 moves in a counterclockwise direction by pushing the bolt down, the arm 10 of the latch bolt, on the one hand, and the rotary slider 45 on the other, move by means of the projection 8, as shown in Figure 2, and in this way the latch bolt 2 is rotated back, and the connecting rod plate 39 is pushed to its initial position ', as a result of which the arm 59 of the latch reset lever 58 is moved by means of the connecting bar 43 coupled so that the slider 68 acts on a projection 69 on the arm 59 and rotates it in a counter-clockwise direction. In the process, as described above, after releasing the latch bolt 50, the arm 60 pulls the latch bolt 50 back onto the projection 61 within the housing of the supplementary lock 49. In FIG. 4 a second exemplary embodiment of the additional lock 49 is shown. With this additional lock 49, the latch bolt 50 has automatically been pushed out of the lock housing when the door is closed. For this purpose, the latch bolt 50 is provided with a groove 70, which extends in its longitudinal direction and opens on one side. A retaining element 71 is located in this groove 70, which is pivotably housed around a clamping sleeve 72 in the slot 70 and thus in the latch bolt 50. This latching element 71 is provided with a projection 73 of retention as well as a projection 74 of activation. In the bolt position shown in FIG. 5, the retaining projection 73 extends behind the cover rail 44 and prevents further extension of the latch bolt 50 which is spring loaded. This spring force, as already mentioned above, is provided by the bolt extension spring 66 (Figure 4), which has been pushed into a guide pin and is supported on one side of the inner wall of the housing of the additional lock 49 and on the other side on the lock extension lever 64. This bolt extension lever 64 is pivotally accommodated in the bearing 65. The end of the bolt extension lever 64 opposite the bearing 65 acts on the end of the locating member 71 located opposite the activation projection 74 and urges it on. the extension direction under the force of the bolt extension spring 66. Since the retaining element 71 is connected by means of the holding sleeve 72 to the latch bolt 50, the latter is also driven in the extension direction. It can be seen in Figure 5 that, although the lock extension lever 64 acts on the retention element 71, the direction of the force of the lock extension lever 64 does not pass through the pivot bearing of the retention element. constituted by the clamping sleeve 71, so that the latch extension lever 64 exerts a pivot moment in the clockwise direction on the retaining element 71. The retention projection 73 as well as the activation projection 74 are rotated out of the slot 70 by means of this pivot moment. When the door is opened (not shown), the latch bolt 50 in this manner is in the bolt position shown in FIGS. 4 and 5, in which further extension is prevented because the latching projection 73 extends behind a cover rail 44.

In the course of closing or pushing the door to close it, the latch bolt 50 is inserted and the additional lock 49 on the closure plate attached to the door frame, not shown. If the door is in its closed position and the latch bolt 50 aligns with the latch opening in the latch plate on the side of the door frame, the latch bolt 50 fully inserted is pushed out of the supplementary lock 49 by means of the bolt extension lever 64. In the course of this extension movement, the closing element 71 is pivoted simultaneously in a clockwise direction around the holding sleeve 72. In the process, the activation projection 74 is brought into contact with the edge of the bolt opening of the closure plate facing towards it, as a result of which the retaining element 71 is pushed against the pivot moment thereby sufficiently far inside the slot 70, so that the retaining projection 73 can slide and pass the cover rail 44. In this way, the retention of the latch bolt 50 in the bolt position, according to FIG. 5, is prevented so that the latch bolt 50 can be extended to its closed position. In this closing position, the latch bolt 50 in the bolt position, according to FIG. 5, so that the latch bolt 50 can be extended to its closed position. In this closing position, the latch bolt 50 has extended approximately 10 mm to 15 mm out of the supplementary lock 49 compared to the latch position, according to Fig. 5. In Fig. 2 there is the suggestion that the bolt tail 31 can be provided with a retaining extension 75 on its underside, which projects downwards and lodges, displaceably in the direction of the double-ended arrow 4, in a receiving groove 76 fixed in the Place in the accommodation. The additional catch 3 is guided by this retention extension 75. Further, when the forward latch latch 3 (not shown) is rotated, the latch extension 75 is pushed out of the receiving slot in the extension direction far enough so that it extends behind the latch 78 of the latch. busbar plate 39, represented by line 77 of lines and points. With the additional latch 3 rotated forward, the connecting rod plate 39 is essentially fixed in place, thus in the position shown in Fig. 2. With its cut 79, the connecting rod plate 39 can only be move between the retention extension 75 (77) and a guide block 80, which is fixed in place in the housing. However, the connection bar plate 39 can not be displaced further back, that is, upwards. When the additional latch 3 has been extended by means of a key, the opening of the lock can not be carried out further by actuating the follower 5.

In figures 6 and 7 a rack extension 81 is shown which is coupled by means of a coupling 82 with a connecting bar 43, not shown. This coupling 82 is located in a first toothed rack 83 which ends in the housing 84 of the rack extension 81. The first toothed rack 83 drives two gear wheels 85 located on the bearings 86 fixed in place on the housing. A second toothed rack 87 is driven by means of these gear wheels 85, which now move in the opposite direction with respect to the first toothed rack 83. Therefore, steering reversal is provided by means of these gear wheels 85. The second toothed rack 87 transmits the movement to two pairs of gear wheels 88 located on bearings 89. The smallest of the gear wheels 90 of this pair of gear wheels 88 is driven by means of the second toothed rack 87. For this end, the toothed rack 87 is provided with a toothed rack element 91 which is constituted to be considerably narrower than the toothed rack 87, but having a greater thickness, which can be seen in figure 6. A third rack 92 Toothed, located laterally after the toothed rack element 91, is of a smaller thickness and engages with the larger gear wheel 93 of the pair of gear wheels 88. Together with the pair 88 of gear wheels, the toothed rack element 91 and the third toothed rack 92 constitute a transmission gear, so that the movement of movement on the connecting rod 43 generates an extension of the holding pin 94 of approximately 25 mm. This detent pin 94 is connected by means of a hook connection 95 to the third toothed rack 92, wherein the lower end of the detent pin 94 is loaded in the extension direction by means of a compression spring 96. In this way, it is possible to uncouple the retaining pin 94 from a further extension of the third toothed rack 92 upon completion of the extension, so that damage to the transmission gear, or respectively the rack extension 81, is generally avoided. The exemplary embodiment shown in Figure 8 shows a further variant of the recessed lock, according to the present invention, wherein the connecting rod plate 39 is provided with a crank 97. A guide pin 101 which projects from a latch extension 102 acts on this level 97, which is constituted by an obliquely extending section 98 and a section 99 extending in the direction of the double-ended arrow 40, as well as a perpendicular end section 100 with regarding this. If the additional latch 3 is driven by means of the rotary element 21, that is to say, by means of a key or the rotary knob, which has been described further above, the guide pin 101 moves on the crank 97. In the course of rotation, the additional latch 3 forwards, the guide pin 101 moves in the direction of the arrow 103. This leads to a movement of the guide pin 101 in the oblique section 98, as a result of which the plate 39 The connecting rod is moved downwards until the guide pin 101 is housed in the end section 100. In this way it is possible to operate the connection bar 43 when moving the additional latch 3 forward, driven by a key or the rotary knob. In addition, in the extended position of the additional latch 3, the "connecting rod plate 39 is blocked so that, as described in relation to FIG. 2, the latching extension 75 shown there extends behind the protrusion 78 of the latch. the plate 39 of the connecting rod In figure 9 a further variant of the lock according to the present invention is represented, wherein the forward movement of the additional latch 3 takes place by driving the follower 5 in the direction of the This lock is also referred to as a "quick lock." With this lock, the connecting rod plate 39 also has a crank 104, which has an oblique section 98, but has an end section 105 that extends in the direction of movement of the connecting rod plate 39. The guide pin 101 is guided in this crank 104. If the follower 5 is now rotated in a direction in the direction of clockwise, the bolt 46, which engages an elongated hole 47 in the connecting rod plate 39, moves downwardly by means of the rotary slider 45. This causes the guide pin 101 to move in the direction of extension of the additional latch 3 in the oblique section 98, which can also be moved downward, as a result of which the additional latch 3 moves forward. In the process, a toothed rack 108 of the latch tail 31 engages with a pinion 107, which in turn engages with a crown gear 106 of the rotary element 21. The rotating element 21 is rotated in this manner by passing the extension of the latch, as a result of which the The arm 23 of the articulated lever 24 is rotated in a counterclockwise direction around the chumsera 27, so that the pivot bearing travels along the curved path 36 described in FIG. 1 and from there the axial projection moves around the projection 37 fixed in place on the housing and placed behind the projection 38. The additional latch 3 is secured against retraction not authorized by this projection 38. However, this pin extension also causes the element to be rotated. 21 rotating, so that the The gear 106 of the crown engages with the toothed rack 108 of the tail 31 of the latch, and the latch 3 moves forward in this manner. However, with the additional latch 3 extended, the toothed rack 108, which becomes appropriately short, is out of engagement with the pinion 107. in each case. If an attempt is now made to move the connecting rod plate 39 upwards, ie in the opening direction, by rotating the follower 5 in a counterclockwise direction, this movement is blocked by the projection 38, fixed in place on the housing, whereby the axial projection of the pivot bearing 28 is brought into contact. Therefore, the latch can not be pushed back past the bolt, or respectively, the follower 5. Therefore, the release can only be done exclusively by means of a rotating element 21, that is, by means of a key or by means of a rotary knob. For this purpose, the rotary element 21 is provided with a ratchet wheel constituted by two discs equipped with saw teeth on the sides oriented towards each other. These saw teeth are placed so that they are permanently in coupling in one direction and, in the other direction of rotation, they are uncoupled starting at a defined torque. The closing of the additional latch 3 by means of the projection 38 fixed in place on the housing is canceled from so that the rotating element 21 is rotated counterclockwise in the direction to open. Since the pinion 107 is out of engagement with the toothed rack 108, the latter, and therefore the additional latch 3, is not carried with it. Even if the arm is rotated of the articulated lever 24, the released pivot bearing 28 opens and disengages from the arm 29. In FIG. 9, the arm 29 has not been removed for clarity. Since the pivot bearing 28 moves on the curved track 36, the axial projection is free of the projection 38 and moves behind the projection 37. The additional latch 3 remains extended, but is no longer secured. It is now possible to move the connecting rod plate 39 upwards by pushing the bolt downwards and by pulling back the additional bolt 3 by means of the crank 104. In the process, the toothed rack 108 again engages with the pinion 107 and drives it, and therefore also to the crown gear 106. Since the rotary element 21 is already in its end position assigned to the open position, the ratchet wheel is driven, so that damage to the rotating element 21 is not caused. In Figure 10 an exemplary embodiment of the lock according to the present invention is shown, wherein the latch bolt 2 has the structure corresponding to the latch bolt 50 shown in Figures 4 and 5. If a door is closed with such lock 1, the locking of the blocking element 109 is automatically canceled and the latch bolt 2 is moved forward by the force of the compression spring 110 acting on the tail 18 of the latch bolt. In the process, the actuating arm 16 of the latch bolt arm 10 is rotated counterclockwise around the bearing 15. The tail 18 of the latch bolt also has a projection 111 which acts on the latch bolt. a lever 112 of blogging, which can be rotated around a bolt 113 fixed in place on the housing. This locking lever 112 extends behind the free end 114 of the connecting rod plate 39 and blocks it against a downward movement, in which direction the connecting rod plate 39 is loaded by a compression spring 115. However, if the locking lever 112 is rotated in a clockwise direction around the bolt 113 past the projection 111, the coupling is canceled behind the free end and the plate 39 of the connecting rod can be removed. move down. With the fully automatic extension of the latch bolt 2, the latch bolts 50 coupled with the connecting rod 43 also extend. A simple latch bolt 50 of this type is shown, for example, in the additional lock 49 in FIG. 11, in which the latch bolt 50 is guided by means of a guide pin 116 in an elongated hole 117 of the cover 118 as well as in the handle 119 of a drive plate 120. This drive plate 120 engages with the connection bar 43. The lock according to the present invention has the essential advantage of having a multitude of conventional components, but can still be used in the North American market.
