Definitions

  • the invention relates to a lock for a door or a window comprising a housing, at least one displaceable via a push rod locking element, a displaceable over a Fallen Wegzugshebel against the force of a spring latch and a lock cylinder and operable by a pusher nut, wherein the locking element and the Trap by rotation of the lock cylinder or alternatively by rotation of the nut are actuated.
  • EP 2706175 A An example of a multi-lock lock is for example in EP 2706175 A disclosed.
  • the locks are usually brought into the release position during unlocking first and only then is the case withdrawn via a change of the lock cylinder, which means a greater rotational movement of the lock cylinder and a torque peak at the end of the movement.
  • the EP 2706175 A solves this problem by the fact that the movement of locking elements and trap over a part of the moving distance is done together when the lock is actuated by the lock cylinder.
  • the lock mechanism is to be changed only slightly compared to existing locks, so that the structure is simple and therefore inexpensive to manufacture.
  • a lock according to the invention should also have the abovementioned construction of EP 2706175 A Further, by simplifying the structure and providing the additional possibility of unlocking via the nut.
  • the nut has a Nussarm, which is guided with a control projection in a link in the push rod, and that the Nussarm, optionally via an intermediate element, can be coupled to the Fallenretzugshebel, wherein the unlocking of a locking position in a release position by turning the nut by max. 45 ° from the initial position, the displacement of locking element and trap over a large part of the movement path takes place simultaneously.
  • the Nussarm coupled so at one point with the push rod and thus with the locking elements and at another point with the Fallenretzugshebel to move over this trap.
  • the backdrop in the push rod and the coupling with the latch retracting lever is designed so that the movement of locking element and latch over a large part of the rotational movement of the nut takes place simultaneously, resulting in no torque peaks at the end of the movement and for the entire unlocking only a very small rotation of the nut is required.
  • the operation of the lock via an electromechanical drive is also particularly efficient realized, since no complex lock mechanics must be moved.
  • the nut arm can be coupled directly to the case retracting lever via an active surface, and that a control extension is provided on the case retracting lever which protrudes into a recess in the push rod, wherein the control extension in the initial position with ejected latch and retracted locking element on a shoulder in the recess of the push rod is applied.
  • This embodiment is characterized by a very simple construction with only a few parts. When operated via the nut, the push rod and the latch retracting lever are simultaneously actuated.
  • the recess in the push rod has a further shoulder in the direction of movement of the push rod opposite the first shoulder, which cooperates in the movement of the push rod in the locking position with the control extension on Fallenretzugshebel and this in the locking position in its lowest End position moves.
  • This has the advantage that the latch retracting lever assumes a defined lower end position in the locking position, whereby it is particularly easy in this position to remove or install the case from the housing for a change of direction.
  • an exchange slide is provided as an intermediate element, which serves the coupling between an actuatable by the lock cylinder change segment and the Fallenretzugshebel upon movement of the lock cylinder from the locking position to the release position, wherein the shuttle has a control surface with a further control projection on the nut arm cooperates, whereby the shuttle and thus the latch retracting lever and the latch are actuated upon movement of the nut.
  • control projection on the nut arm for coupling with the push rod and the further control projection for coupling with the shuttle are arranged on opposite sides of the Nussarms.
  • the coupling to push rod and change lever can be implemented in a particularly simple and space-saving.
  • a normal to the direction of movement of the push rod movable in the direction of the push rod biased by a spring pressure piece is provided which cooperates with a locking shoulder or recess on the push rod and secures the push rod in the starting position. This makes it possible to secure the push rod in a starting position with withdrawn locking elements and extended latch with very few components.
  • the in the Fig. 1 shown embodiment of a lock according to the invention comprises a housing 1, in which a push rod 2 is arranged to be vertically displaceable.
  • a locking element 3 is displaceable normal to the direction of movement of the push rod 2, wherein the locking element 3 is guided by means of a control pin 27 in a corresponding link 26 in the push rod.
  • the push rod 2 in the lowest position, whereby the locking element 3 is fully ejected.
  • a case 6, which is biased by a spring 5 in the extension direction.
  • the trap can be withdrawn via a case retracting lever 4 against the force of the spring 5 in the housing 1.
  • a lock cylinder 7 and a nut 8 are provided for actuating the lock.
  • Other drives, such as an electromechanical drive can also be provided for lock actuation.
  • the nut 8 has a Nussarm 9, at the end of a control projection 10 is arranged, which engages in a corresponding link 11 in the push rod.
  • the latch retraction lever 4 has at its free end an active surface 12 which cooperates with the Nussarm 9 when it is rotated in the release direction.
  • the latch retraction lever 4 also has a control extension 13, which engages in a recess 14 in the push rod and, depending on the lock position, interacts with corresponding shoulders 15, 16 in the recess 14.
  • a control extension 13 of the latch retracting lever 4 engages in a recess 14 in the push rod and, depending on the lock position, interacts with corresponding shoulders 15, 16 in the recess 14.
  • the lock by turning the nut 8 in the release position brought as in the Fig. 2 is shown, the control projection 10 of the Nussarms 9 slides along the gate 11 in the push rod 2 and raises it, whereby the locking element 3 is displaced into the housing interior.
  • the nut arm 9 comes into contact with the active surface 12 of the latch retracting lever 4 and thus also pushes it upwards, as a result of which the latch 6 is also pulled into the housing 1 at the same time as the displacement of the locking element 3.
  • the nut 8 only needs to be extended by max. Be rotated 30 °.
  • a locking lug (not shown) of the lock cylinder acts on a locking segment 24, which engages with a corresponding control extension 25 in an associated link 28 in the push rod 2.
  • Fig. 3 is the castle from the Fig. 1 and 2 shown in initial position.
  • the push rod 2 is secured just below the upper position with retracted locking element 3 by a pressure piece 22 which is biased by a spring 21 in the direction of the push rod 2 and rests against a corresponding latching shoulder 23.
  • the nut 8 is rotated back by the nut spring 30 via the nut lever 29 in the neutral position, which is also made possible by a corresponding release in the slot 11 for the control projection 10 on the nut arm 9.
  • retracting lever 4 is located on the lower shoulder 15 in the recess 14 of the push rod 2 at.
  • the case 6 can be operated not only on the nut 8, but also on the lock cylinder 7, which displaces by means of the locking segment 24 in rotation in the opening direction, the push rod further up, whereby the Fallen Wegszugshebel 4 by cooperation of the shoulder 15 with the control extension 13th taken and the case 6 is pulled into the housing interior.
  • Fig. 4 shows an alternative embodiment of a lock according to the invention, which has an exchange slide 17 as an intermediate element between Nussarm 9 and Fallenretzugshebel 4.
  • the shuttle valve 17 is parallel to the direction of movement of the push rod 2 movable.
  • the lock is shown in locking position. Now, the lock is moved by rotation of the nut 8 in the release position (see Fig. 5 ), so the Nussarm 9 engages exactly as in the embodiment according to the Fig.
  • Fig. 6 is shown for a better view of the shuttle 17 in detail.
  • the Nussarm 9 engages with its further control projection 20 (see Fig. 7 ) on the control surface 19 and slides along this, when the shuttle 17 is raised. If the change slide is actuated via the lock cylinder 7, then the corresponding change segment engages on the free end 33 of the change slide 17 in order to displace it.
  • Fig. 7 shows the nut 8 with the nut arm 9 in a perspective view.
