Description

The invention relates to a self-locking lock. Such locks are already known.

From the DE 202005007311 U1 a lock according to the preamble is known in which the main catch engages with a pin in a slot-shaped control slot of a slider whose movement is controlled by the main trap. The engagement of the pin in the control slot causes a direct coupling of the main trap and the slider, which controls the secondary traps. If, as a result of a fault in the wing, the main lock catch moves forward or backward, the secondary lock traps do not or only partially engage in the associated bolt engagements and the wing is not fixed to the frame.

From the WO 03/095774 A1 a motor-operated lock is known in which the main lock latch is retractable via a drive rod slider. For this purpose, a pin attached to the latch tail engages in a control slot of a drive rod slide. The main latch and the latches can be moved via the motor drive. The main lock catch can also be brought into a locked position via the espagnolette. An extension of the control slot is provided and allows a prevailing in Fallenfunktionsstellung main lock trap. However, retraction of the main latch requires the action of an additional lever. Therefore, the design is a total of consuming.

From the DE 8909801 U1 is known an espagnolette in which, starting from a main lock box espagnolettes are guided along a faceplate to latch elements. The drive rod is displaced against the force of a spring when setting an open position, which is thereby tensioned. A trigger is provided, which fixes the drive rod in the tensioned position of the spring and is triggered when closing the wing by contact with the frame. In this known embodiment, the drive rods can also be operated presser operated. It is provided a lock nut, which acts by means of a link plate on a lever which cooperates with the drive rod and a drive rod slider.

The embodiment provides a 45 ° up-adjustment movement to move the drive rods downwards, in the direction of gravity. Accordingly lock all locking elements in the direction of gravity. As a result, the locking elements, especially when it comes to along the cuff rails displaceable locking elements is, shifted downwards. This also happens when the drive rods are displaced by the spring. As a result of a lowering of the entire wing, it comes firstly to the fact that the locking elements reach the engagement ends of the frame-side locking engagements and create it. The generated operating forces now act on the drive rod drive and the locking elements are loaded in an undesirable manner by the wing. The arrangement of the link plate is complex and requires a lot of space.

From the DE 19617082 A1 is known an espagnolette lock, wherein the lock nut cooperates via an external toothing with a lever. Due to the configuration, an automatic locking is not possible.

The invention is therefore based on the object to provide a lock according to the preamble of claim 1, which avoids the deficiencies in the cited prior art.

To solve a lock with the features of the main claim is proposed. Due to the configuration, a direction of rotation change is achieved by the reversing lever, which leads to an acting in the direction of gravity unlocking movement of the drive rods. The locking elements lock in their closed position against gravity upwards. If the forces caused by the spring are insufficient, the locking can be done manually via the pusher. The embodiment according to the invention provides that the guide contour is a boundary edge of a triangular opening of the slider whose hypotenuse forms the guide contour and whose catheters run along the direction of displacement of the case and transversely thereto. The trap can be moved unhindered and without displacement of the slider in the housing. Particularly space-saving is an embodiment in which the previously made embodiment also provides that the slide is spring-loaded in the direction of the nut and this is assigned via a circumferential cam. This eliminates the need for a space-consuming Nussarm and allows the installation of rosette screws near the nut.

A further development of the invention provides that the spring forces the drive rod or the espagnolette against the force of gravity. This also ensures the automatic operation of the lock.

Due to the fact that the nut has a toothing which cooperates with the lever over an angle range of 45 °, it is achieved that the pusher is inclined downwards by 45 ° Unlocking and after passing through a clearance by means of stop surfaces on the nut parts 90 ° upwards to lock is movable.

In order for the lever handle to be fixable in its horizontal normal position and the position at 90 ° vertical, the nut has two fixation interventions for a fixing spring offset by 90 °.

In order to prevent the resulting operating noise and damage to the lock components, it is provided that the spring is mounted in a spring housing, in which the drive rod slider engages with an angled tab and that in the spring housing an elastic stopper is mounted, against which the tab abuts in the locked position ,

A simpler right-left usability with high functionality is given if the trigger is formed by a transverse to the drive rod movement direction locking lever.

To save space, the locking lever is arranged in the main floor box, to the locking lever is assigned a blocking surface of the espagnolette.

In order to retract the case in handle operation, it is provided that the case is associated with a slide having an engagement opening for a pin attached to the case, which is associated at least in the leading position of the case a guide contour of the slide, which upon retraction of the slide retreat causes the trap.

In order to achieve a secure locking, it is provided that the espagnolette is assigned to the bolt via a Z-shaped link, in which engages the latch with a driving pin.

In particular, for the application of the lock as an outer door contributes that a Schließzylindermitnehmer cooperates with a slider which is displaceable along the direction of locking of the bolt and engages with a boom on a blocking surface of the two-piece shaped nut. So the pusher can be detected by a key operation.

In order to effect an extended anti-burglary protection, it is further provided that the locking slide forms two locking surfaces, wherein the locking surface of the locking edge of the nut and the locking surface is associated with a locking projection of the espagnolette. By this measure, the locking slide secures both the nut and the espagnolette and also relies on this.

A second embodiment of the locking device of the nut.

At the in Fig. 1 The lock shown is the main lock case 1, omitting the lock cover. In the housing 2, a drive rod slider 3 is slidably guided. On the fold side, a faceplate 4 delimits the housing 2. Behind the face plate 4, a drive rod 5 is guided so as to be longitudinally displaceable. In the region of the housing 2, the espagnolette 3 connects the drive rod 5 to a drive rod 6.

In the housing 2, a latch 7 and a latch 8 are also provided. Furthermore, a nut 9 is rotatably mounted in the housing 2 for operating the lock. This is rotatable by means of a pusher, which passes through the square recess with a square.

In a spring housing 10, a spring 11 is also mounted. In the spring housing 10 engages the drive rod slide 3 with a tab 12 a. The spring is supported in the representation at the lower stationary end of the recess 13, while the free end of the tab 12 is associated. In the recess 13 between the tab 12 and the spring housing 10 further includes an elastic stopper 14 is attached. Against this, the tab 12 strikes in the locked position, as will be explained below.

In the illustration after Fig. 1 the lock is press-operated in the open position, ie the pusher and thus the nut 9 is pivoted from a horizontal slightly 45 ° down. The nut 9 has a toothing 15 extending over a partial circumference of approximately 45 °, which meshes with a corresponding toothing of a reversing lever 16, which is rotatably mounted in the housing 2. The reversing lever 16 has a lever 17 which forms a claw 19 together with a cam 18. The lever 17 and the claw 19 are associated with a driver lug 20 which is fixed to the espagnolette 3 and raised perpendicular to the plane of the drawing this executed. The driver lug 20 is on the side facing the espagnolette 3 side substantially L-shaped, wherein at the intersection and each leg end point attachment lugs are assigned to the espagnolette 3. A lower - not visible in the drawing - leg is horizontal and is assigned to the lever 17 in the illustrated switching position. The handle operation has therefore related to the representation - a clockwise rotation of the nut 9 and an oppositely directed rotation of the reversing lever 16 result. The espagnolette 3 is thereby displaced downwards, the spring 11 clamped by means of the tab 12.

At the same time, the nut 9 moves with a cam 21 a slider 22 upwards. The slider 22 is spring-loaded in the direction of the nut 9 in the housing 2 and the spring housing 10 and the nut 9 associated with a fork-like end. The slider 22 acting on the spring is also mounted in the spring housing 10. The latch 7 is associated with the slider 22 at the latch tail 23, in which a pin 24 engages in an engagement opening 25. Upon the displacement of the slider 22 from the pusher-horizontal position to Fig. 3 slides the pin 24 from the leading position of the case 7 along the guide contour 26 of the slider 22 in the in Fig. 1 shown position, causing a retreat of the case. 7

Evidently the FIGS. 1 and 3 It can be seen that the guide contour 26 is a boundary edge of the triangular engagement opening 25 of the slider 22, the hypotenuse forms the guide contour 26 and the catheters 27, 28 along the direction of displacement of the case 7 and transverse thereto. The catheter 27 guides the pin 24 when the latch 7 is urged into the housing 2 without handle operation, for example when the blade is closed by frame contact.

This protrudes through a window 32 of the forend 4 and is pivotally mounted transversely to the espagnolette movement direction in a 90 ° angled housing bottom plate tab in front of the forend 4. A U-shaped spring 33 is mounted such that in each case a spring leg a provision of the trigger 31 in a center position Fig. 1 causes. The rear side of the trigger 31 forms a blocking surface 34, which is assigned in un-pivoted position of the trigger 31 a mounted on the cam projection 20 blocking surface 35. As a result, the espagnolette 3 is prevented in centrally oriented trigger 31 in an upward movement. The spring 11 remains taut.

The in Fig. 1 recognizable small distance of the locking surfaces 34, 35, which is necessary for the pivoting of the trigger 31 in the center position, is due to by the handle operation occurred displacement of the espagnolette 3 ago. If the pusher in its horizontal position, sets the blocking surface 35 as a result of the spring 11 taking place taking place on the blocking surface 34 ( Fig. 2 ).

The Fig. 2 also shows that the latch 7 in the horizontal position of the pusher in front of the forend 4, which is caused by the latch spring 36. The espagnolette 3 and thus also the drive rods 5 and 6 remain due to the interaction of the trigger 31 with the cam projection 20 in the open position. The nut 9 is fixed in position counterclockwise by a fixing spring 37 in the clockwise direction by the slider 22 with its fork on the cam of the nut 21. For this purpose, the fixing spring 37, which is mounted as an L-shaped leg spring in the spring housing 10, with a leg 38 on the peripheral surface of the nut 9 and engages in a recess 39 thereof a. The comparatively short leg 38 causes a stable fixation of the nut 9. Die Fig. 2 thus represents in the open position of the wing is a ready position of the castle.

If the wing is now closed, the trigger 31 reaches the frame or a frame part attached thereto and is deflected laterally ( Fig. 3 ). The deflection of the trigger 31 allows the blocking surfaces 34, 35 to slide past one another and the spring 11 displaces the driving rod slide 3 and the driving rods 5, 6 in their locking position against the force of gravity. The espagnolette 3 is associated with the bolt 8 via a Z-shaped link 40, in which the bolt 8 engages with a driving pin, so that the bolt 8 enters.

If it comes in the course of adverse circumstances, such as delay of the wing after a lapse of time or other events that the force of the spring 11 is insufficient to fully retract the locking elements in the bolt engagements, the pusher can be additionally placed in an upright vertical position, the in Fig. 4 is shown. The spring 11 is relaxed because the trigger 31 is activated. The pusher pivoting movement starting from Fig. 3 leads to a pivoting movement of the nut 9 in the counterclockwise direction. This causes after overcoming the clearance between the nut parts a pivoting movement of the reversing lever 16 in a clockwise direction, which causes the cam 18 engages under the catch lug 120 and this transported in the drawing upwards. The fact that the nut 9 cooperates with a reversing lever 16, there is a reversal of direction, which allows an upward and against gravity directed shutter movement. The claw 19 engages the underside of the driver lug 20 mounted horizontal leg.

At the end of the pivoting movement of the nut 9, the fixing spring 37 engages in a second recess 41 on the circumference of the nut 9. As a result, the nut 9 is also in this position, in the pusher stands vertically fixed. The recesses 39, 41 form fixing engagement and are offset by 90 ° to each other. Overall, the nut 9 acquires a Gesamtverschwenkbereich of 135 °, wherein nut 9 and lever 16 cooperate with each other through the teeth 15 over a pivoting range of 45 °.

For further operation of the lock, a lock cylinder 45 is providable, which is received in a cylinder bore 46. The cylinder has a driver 47 which can be assigned to a slide 48. The slider 48 allows a one-way operation of the lock cylinder 45, wherein the slider 48 in the Fig. 5 is shifted to the left. A guided in the same direction in the housing 2 locking slide 49 attacks as evidenced by Fig. 6 on the underside of the slider 48 and is displaced together with this after passing through a clearance 50. Mounted on the castle floor, the locking slide 49 extends to the nut 9 zoom. The nut 9 is shown in the Fig. 7 executed in two parts, wherein the square 51 is performed in a lower nut part 53 inner nut part 52. The lower and the inner Nussteil 52, 53 are limited to each other pivotally, which is achieved by radial projections 54 of the inner Nußils 52, which is associated with a clearance 55 on the lower Nußsteil 53. The clearance 55 is dimensioned such that upon actuation of the lock on the trigger 31, the pusher is not moved and the projection 54, the clearance 55 passes completely through to finally abut the projection 54. Will now be in Fig. 6 In a rear view locking slide 49 shown on the slider 48 to the nut 9 towards shifted, he engages behind a locking edge 56 on Nussteil 53. The Nussteil 53 is thereby locked in the opening direction, whereby the pusher from the upright position can be pivoted back without the lever to perform a movement.

In the Fig. 8 is another one in Fig. 6 shown blocking device shown. The locking slide 49 is also by the shooting cylinder 45 and the slider 48 in the in the Fig. 8 recognizable blocking position relocatable. The blocking surface 57 of the locking slide 49 thereby passes into the pivoting region of the locking edge 56 of the nut 9 and inhibits a rotation of the nut 9 and a pusher coupled thereto. Simultaneously, the locking slide 49 arrives with its locking surface 58 in the displacement region of the espagnolette 3, which forms a locking projection 59 to cooperate. At the same time, the locking slide 49 applies with its edge 60 to the espagnolette 3. The locking slide 49 locks as a result of this engagement, a downward movement of the espagnolette 3. This also results in a blocking effect on the lever 16, which in turn prevents the nut 9 from rotating. The escape of the locking slide 49 is difficult as a result of the support thereof in the main lock box 1 and the espagnolette 3.

As already described above, the above-described push-button self-locking lock is characterized in that the nut 9 interacts with a deflection lever 16 which is coupled to the drive rod 5, 6 or the drive rod slide 3.
