Definitions

  • the invention relates to a locking device for a door or a window with a lock box and a latch bolt arranged displaceably therein, which can assume an open position, a closed position and a locking position, the latch bolt having a latch shaft and with a latch bolt from the closed position into the locking position transferring locking element is provided, wherein the locking device also has an additional latch, wherein a shifting of the latch bolt from the closed position into the locking position blocking element is provided in the lock box, the latch bolt has a locking element on which the blocking element engages and the blocking element off by means of the additional latch is led out the way of the locking element.
  • Such a facility is, for example, off US 5469723 known, which corresponds to the preamble of claim 1.
  • a mortise lock is also from the EP 0 431 369 A2 known.
  • its latch bolt only protrudes from the lock cuff with its frontal bevel in the door open position, but has the advantage over the latter that the latch bolt automatically moves deeper into the strike plate on the door frame side in the door closed position, which is already through this deep locking engagement, the door is more secure against being broken.
  • the latch bolt in its fully extended locking position in which its approach slope disappears completely in the strike plate, cannot be moved back into the door gap between the door lock and strike plate by unauthorized introduction of a sufficiently rigid object, such as a flexible sheet metal, screwdriver or a credit card. as is easily possible with simple latch locks.
  • the locking element locking the latch bolt in its partially extended intermediate position is designed as a pawl loosely mounted under spring action in a groove-shaped recess of the latch bolt, while the trigger protrudes over the latch bevel so that it is actuated when the door is closed and this releases the latch bolt for its full extension movement.
  • the front side accessible position of the trigger on the latch bolt has the disadvantage that it can easily be operated manually with the door open and thus adjusted, whereby the latch bolt can unintentionally move out prematurely into its fully extended position. If the door is carelessly slammed, this can lead to considerable damage.
  • the possibility of malfunction described above could mean that such a lock may not be used in fire protection doors.
  • the DE 44 07 244 C1 and the DE 197 01 761 C1 show locks with an auxiliary latch via which a slide plate is actuated that locks the bolt and / or the latch separately. A manipulation of the latch bolt is therefore not easily possible.
  • the object of the invention is to provide a locking device which is even more secure against manipulation.
  • the displacement of the latch bolt is blocked or prevented if it is not properly actuated.
  • the trigger accommodated in the latch bolt can still be actuated with the door open, this does not mean that the latch bolt is shifted from its closed position into the locking position.
  • the latch bolt is unlocked in its closed position, but cannot extend any further because it is blocked from moving in the outward direction.
  • the door can be closed without any problems, since the latch bolt can still be pushed in because it only protrudes over the cuff with its section having the latch bevel.
  • the locking element can be displaced in the displacement direction of the latch bolt. This locking element has the task of preventing the latch bolt from shifting if the door has not been properly closed. Since the locking element is located in the lock box, it is protected from manipulation.
  • the locking element is formed by a pin protruding transversely to the direction of displacement of the latch bolt and transversely to the direction of displacement of the blocking element.
  • This pin is either integrally formed on the latch bolt or bolted to it.
  • the pin is preferably located on the latch shaft so that its position within the lock box is always the same and independent of the box width and the backset.
  • the blocking element is slidably mounted in the lock box transversely to the direction of displacement of the latch bolt and in particular in the plane of the lock box or mortise lock. This makes it possible in a simple manner for the blocking element to be able to assume a position in which it lies without collision with the latch bolt or engages in its displacement path and can block it.
  • the blocking element has a recess which is open at the edge against the pushing-out direction of the latch bolt.
  • the pin is advantageously caught, so that in the blocking position of the blocking element, the locking element lies in the recess.
  • the latch bolt can still be pushed into the lock box, since the pin can leave the recess in the direction of insertion of the latch bolt, ie it can step out.
  • the additional latch In order to be able to easily transfer the movement of the additional latch, in particular its insertion movement, to the blocking element, the additional latch is coupled to a drive for the blocking element.
  • the direction of movement and / or the length of the path of the insertion of the additional latch can be adapted to the requirements of the blocking element.
  • the displacement movement of the additional latch is decoupled from the blocking element via the drive. This is e.g. required in the event that the additional latch is inadmissibly or unintentionally actuated manually when the door is not closed.
  • a preferred embodiment of the invention provides that the drive has a drive housing and a plunger mounted displaceably in the drive housing.
  • the additional latch acts on an end face of the ram, the ram being supported with its opposite face against the force of a first spring on the drive housing. The position of the additional latch is thus transmitted directly to the punch, whereas the position of the punch is transmitted to the drive housing as a function of the force. If the counterforce is greater than the force of the first spring, the drive housing remains in its current position and the first spring is compressed.
  • the drive housing is preferably mounted displaceably in the lock box.
  • the drive housing drives a pivot lever which engages the blocking element with a first pivot arm.
  • the swivel arm has the advantage that it can be used to set the lever forces required to move or swivel the blocking element as required.
  • the mounting of the swivel arm is relatively simple, since only one bearing pin is required.
  • a further development of the invention provides that the pivot lever is urged by a second spring into a rest position corresponding to the blocking position for the blocking element.
  • This second spring generates the counterforce for the first spring and serves to return the pivot lever and the blocking element to the initial or blocking position.
  • the spring force of the first spring on the plunger is greater than the spring force of the second spring on the pivot lever.
  • the spring force of the second spring is thus overcome by the drive so that the pivot lever and the blocking element are actuated.
  • the blocking element is retained when the latch bolt is in its closed position and has not been moved into its open position, then the first spring is compressed as soon as the plunger is displaced.
  • the free end of the first pivot arm runs in a link of the blocking element.
  • the backdrop is advantageously realized by a pin-and-groove connection.
  • a preferred connection of the drive housing and pivot lever is achieved in that the pivot lever has a second pivot arm and the free end of the second pivot arm engages in a recess on the drive housing.
  • the recess on the drive housing works like a rack, whereas the free end of the second swivel arm acts as a tooth that engages in the rack.
  • the position of the additional latch with respect to the ram can be positioned in an adjustable manner. This takes place in that the additional latch can be pushed more or less far into the punch and the one in the desired position can be locked.
  • the Figure 1 shows a section of a locking device denoted overall by 10 with a lock box 12 in which a latch bolt 14 is displaceably guided.
  • a latch bolt 14 is displaceably guided.
  • an additional latch 16 encased in plastic and thereby noise-insulated can be seen, which in this embodiment is also arranged in the lock box 12. she but could also be accommodated in an additional box, the additional box being mechanically coupled to the lock box 12 via suitable connecting means.
  • the latch bolt 14 takes in the Figure 1 its locking position and is completely extended out of the lock box 12, which takes place via a latch spring 18 which is supported on the lock box 12 and engages a latch shaft 20 of the latch bolt 14 at the rear.
  • the additional latch 16 is connected to a drive 32, which will be described in detail later.
  • the Figure 2 shows the lock box 12 with the latch bolt 14 in the closed position, which only protrudes over a cuff 34 with its latch slope.
  • a locking element 36 in the form of a pin 40 which protrudes transversely (orthogonally) to the direction of displacement and which engages in an open-edged recess 42 at the end of the blocking element 22.
  • the recess 42 is open against the direction of displacement 38 and holds the pin 40 in a form-fitting manner.
  • the blocking element 22 also extends transversely to the displacement direction 38 and transversely to the locking element 36 and is mounted so as to be vertically displaceable in the direction of extent.
  • the blocking element 22 has a bent or curved elongated hole 44 which is part of a link 46 to which a pin 48 which engages in the elongated hole 44 and projects from the end of the first pivot arm 28 also belongs.
  • the end of the second pivot arm 30 engages in a recess 50 of the drive 32.
  • the drive 32 has a punch 52 and a drive housing 54 which receives the punch 52 and on which the recess 50 is provided.
  • the additional latch 16 is mounted in the punch 52 and the punch 52 is supported on the base of the drive housing 54 by means of a first spring 56, a helical spring.
  • a second spring 58 a leg spring, can be seen which is looped around the pin 26 and urges the pin 48 counter-clockwise. The spring force of the second spring 58 is smaller than the spring force of the first spring 56.
  • the latch bolt 14 When the latch bolt 14 snaps into the latch receptacle of the strike plate on the fixed frame when the door is closed, the latch bolt 14 moves from its open position to the closed position according to FIG Figure 3 into the locking position according to Figure 1 .
  • the additional latch 16 can remain depressed.
  • the additional latch 16 also moves out of the lock box 12 again, so that the blocking element 22 resumes its starting position, into which it is urged by the link 46, supported by the second spring 48.
  • the pin 40 is then located between the cuff 34 and the blocking element 22, which has a nose 60 at its end, which secures the position of the pin 40.
  • the latch bolt 14 cannot be pressed into the lock box 12 by means of a tool.
  • the Figure 4 shows the same situation and position of the components as the Figure 2 . If the additional trap 16, as in Figure 4 shown, for manipulation purposes, for example manually pressed into the lock box 12, then the punch 52 is moved. The drive housing 54 is, however, blocked by the blocking element 22 caught by the pin 40 and the pivot lever 24, so that the first spring 56 is compressed. As soon as the additional latch 16 is released, it is pushed out of the lock box 12 again via the first spring 56.
  • the Figure 6 finally shows a device with which the protrusion of the additional latch 16 over the cuff 34 can be adjusted.
  • the additional latch 16 has a latch shaft 62 which is mounted in the punch 52. On the latch shaft 62 there are several notches 64 next to one another in the manner of a toothed rack, in which the tip of a grub screw 66 engages, which is screwed into the punch 52. If the protrusion of the additional latch 16 is to be adjusted, the grub screw 66 is loosened, the position of the latch shaft 62 in the punch 52 is changed and the grub screw 66 is fixed in such a way that it engages in another notch 64.
