Definitions

  • Locking unit means in the context of the invention, in particular an additional locking of an espagnolette lock or a central lock of an espagnolette lock. Additional locks on the one hand and handle and key-operated central lock are connected in a conventional manner via connecting rods, so that in the course of locking not only the central lock arranged in the central lock, for example, but also arranged in the additional locking locking elements (in particular latch bolt) are excluded.
  • the invention thus relates to a self-locking locking unit or a self-locking lock, which is also referred to in practice as an automatic lock. Characteristic of such an automatic lock is the fact that the locking elements, for. B. the latch bolt of the additional lock, automatically enters the locking position when the door is closed.
  • the invention relates to an embodiment with magnetic release, that is, it is provided a release magnet, which is preferably arranged in or on the (frame-side) locking bar.
  • a release magnet which is preferably arranged in or on the (frame-side) locking bar.
  • Such a locking unit is z. B. from the DE 10 2008 011 551 A1 known.
  • the locking element is designed as a latch bolt, wherein the latch bolt is forcibly coupled to the lock chain via an intermediate lever.
  • Such an embodiment with magnetic release has proven excellent in practice, but it is capable of further development. - This is where the invention starts.
  • a conventional latch is provided which is slidably supported between an extended position and a retracted position.
  • the latch of the secondary lock and the locking element of the secondary lock are each associated with a frame-side recess, which engages in which located in the locking position locking element of the secondary lock or in the extended position located latch of the secondary lock in the closed position of the castle.
  • the locking element can, for. B.
  • the latch is a conventional latch which is spring loaded and occupies an extended position when unloaded. The latch thus runs when closing the door with its inclined surface against the frame and is thereby pressed in the direction of its retracted position.
  • the latch of the secondary lock is coupled via a pivot lever with a transmission element such that upon actuation of the pusher the main lock and an associated movement of the drive rod, the latch is brought against the force of the spring element in the retracted position. When the trigger is released, the latch automatically returns to the extended position by means of the force of the spring element.
  • the position of the wing in the vicinity of the secondary lock should be fixed so that the swivel hook in the course of the triggered by the swinging of the wing self-actuated lock freely and without friction can enter the associated opening of the frame-side strike plate.
  • a partial retraction of the latch is sufficient to ensure the desired defined position of the wing.
  • the latch is thus decoupled from the automatic locking effecting automatism and can get into the extended position and fix the wing in the desired position, even before the automatic locking of the locking element takes place or is triggered.
  • the EP 2 543 802 A2 a lock with a latch and a locking element and with at least one securing element which is adjustable by means of a securing element and a frame-side triggering element acting magnetic attraction or repulsive force between a securing position and a Enttechnischswolf.
  • the locking element is held by this securing element in the unlocked position.
  • the locking element is to be held by the located in the retracted position latch in the unlocked position.
  • the triggering of the automatic locking should be controlled by a double fuse, namely once by that in the unlocked position located locking element is held by the securing element located in the securing position in the unlocked position and once by the fact that the locking element located in the unlocking position is held by the located in the retracted position latch in the unlocked position.
  • a double fuse namely once by that in the unlocked position located locking element is held by the securing element located in the securing position in the unlocked position and once by the fact that the locking element located in the unlocking position is held by the located in the retracted position latch in the unlocked position.
  • a locking device for a door or a window which has a main lock box and at least one secondary or additional lock case
  • the secondary lock case has a freelytechnischschannabaren in unlocking latch and at least one latch bolt is displaced by a latch spring beyond the case position into a locking position.
  • the latch bolt forms a locking device for the drive rod, which is urged spring or gravity loaded in a locking position.
  • the self-release is done mechanically by special locking and release elements in or on the latch bolt.
  • the invention is the technical problem of providing a locking unit for a locking system of a door, in particular for a drive rod lock with multiple locking, which ensures a reliable and reliable self-locking by magnetic release at the same time increased burglary protection.
  • the invention teaches in a generic locking unit of the type described above, in addition to the sliding latch bolt a (pivotable about an axis) pivot hook latch is mounted in the lock housing, in its pivoted-out locking position, the locking bar or the striking plate or an element engages behind or in the closing strip and (for-) coupled with the lock chain so that he with the lock chain from a pivoted unlocking position, (ie lock chain in neutral unlocking) in a swung-out locking position (ie lock chain in lowered locking position) can be transferred and vice versa, wherein the pivot bolt is (only or only then) in the closed position reaching door in the (fully) swung out locking position when / when the latch bolt reaches a partially extended limit position or passes over, in which the latch bolt by a limit measure (of eg. 13 mm) which is greater than the unlocking dimension (eg 10 mm) in the unlocked position and which is also smaller than the locking dimension (eg about 20 mm) which the latch bolt
  • the invention is initially based on the recognition that a simple and at the same time manipulation-safe self-locking by magnetic release, taking into account a provided in the locking unit locking element is appropriate, which either blocks or releases the independently movable lock chain in the lock case.
  • complicated mechanical release mechanisms which in the prior art z. B. are integrated in a latch bolt or by Separate release lever can be realized omitted.
  • the magnetic self-release is characterized by high security against manipulation, since a manipulation with purely mechanical means is not possible.
  • a pivotable swivel hook bolt is provided in addition to the sliding latch bolt, not in combination with a simple latch, but in combination with another locking element, namely a latch bolt, so that Combination of the two locking elements ensures a particularly high level of security.
  • the two locking elements namely latch bolt on the one hand and swing hook latch on the other hand, go to magnetic release of the locking element in their locking positions.
  • these locking operations are not realized simultaneously, but with a time delay, because the pivot hook latch is only extended when the latch bolt is already immersed by a certain amount in the locking bar, so that the latch bolt not only a lock, but also a pre-centering of the door takes place and thus dipping the pivot hook latch reliably in the region of the closing strip and can engage behind the locking bar or an element arranged therein or in it.
  • the pre-centering does not take place with a simple spring-loaded latch, but with a latch bolt not only a defined fully extended (non-return) locking position, but also a defined, partially extended (not pressed-back) unlocked position can take.
  • the latch bolt is not completely positive or positively coupled coupled to the lock chain, so that a certain kinematics of the latch bolt is also possible regardless of the movement or position of the lock chain.
  • a coupling between the lock chain and the latch bolt is preferred only implemented such that the latch bolt by movement of the lock chain (in particular by lifting the lock chain) from the (fully extended) locking position or from the (partially extended unlocking position) in the fully retracted open position is retractable.
  • the z. B. is connected to a drive rod, withdraw and open the lock.
  • a coupling between the lock chain on the one hand and the latch bolt on the other hand is realized such that the latch bolt is held on the lock chain and the latch lever in the partially extended unlocking position.
  • no support is provided by the lock chain, ie the extension into the locking position does not take place by the displacement of the lock chain, but solely on the force of a latch spring, because the latch bolt is spring-loaded in the closing direction .
  • the coupling of the latch bolt with the lock chain is therefore particularly limited to a coupling in the unlocking or opening direction, ie in the course of lifting the lock chain.
  • the lock chain after release by the locking element (as a result of a magnetic release) held by the latch bolt, d. H. blocked against lowering until the spring-loaded latch bolt reaches the partially extended limit position.
  • Such blocking of the lock chain up to partially extended limit position of the latch bolt can be realized by suitable structural design of the lock chain on the one hand and the latch bolt on the other hand, so that the latch bolt blocks the lock chain immediately.
  • the operative connection between the latch bolt and lock chain in the course of a blockage via an additional element, for. B. realized an additional control lever, via which the lock chain is in operative connection with the latch bolt. If the lock chain z. B. released after a magnetic release by the blocking element, it is not immediately a complete lowering of the lock chain, but the lock chain is held by the control lever until the spring-loaded latch bolt reaches the limit position.
  • the latch bolt with the lock chain is thus on two elements or two levers in operative connection, namely on the one hand the latch lever, in particular in the course of unlocking and consequently in the course of raising the lock chain significance and on the other hand via the control lever, which in particular in the course of sinking the lock chain after an automatic triggering importance.
  • the control lever can also be equipped as a pivoting lever, the z. B. is pivotally mounted about a horizontal axis.
  • This control lever itself is not spring loaded. It may also be appropriate that the latch lever itself is not directly spring loaded. However, it is preferably provided that on the one hand the latch bolt is directly spring-loaded, for example by a leg spring or a comparable spring element which acts in the extension direction on the latch bolt.
  • the lock chain can be directly spring loaded, namely for gravity support, d. H. The lock chain is not only about gravity, but in addition to the force of another spring, z. B. a leg spring, pressed into the locking position and thus in the lowered position.
  • the control lever preferably has a (end) control cam acting as it were between latch bolt on the one hand and lock chain on the other hand. So this control cam on the one hand by the latch bolt, z. B. an actuating surface or an actuating edge of the latch bolt are actuated and on the other hand, this control cam can then act on the lock chain and thereby lift.
  • the lock chain itself may have a corresponding control contour, on which the control lever, z. B. whose control cam works. The control contour is designed so that the described blocking function of the lock chain is guaranteed until the spring-loaded latch bolt reaches the partially extended limit position.
  • the burglary and tamper resistance of the locking unit is increased by that on the one hand a latch bolt and on the other hand, a pivot bolt are provided, wherein the latch bolt not only takes on a case function, but is itself designed as a locking element.
  • the latch bolt is self-locking, z. B. with at least one additional securing element which secures the latch bolt in the extended locking position against a pushing back.
  • the latch bolt is double-backed or two-stage non-return, not only in the (fully) extended locking position, but also (already) in or from the partially extended limit position, from which then also extends the pivot hook latch. It can be z. B.

  • the latch bolt is also (already) then non-return secured when the latch bolt has moved out to the limit position (or beyond).
  • an additional safety lever or locking lever can be provided.
  • this backup can be realized in the limit position but with the help of the control lever already described in cooperation with the lock chain.
  • the locking system is characterized in this case by special manipulation and burglary security, because the latch bolt is back-secured even if the latch bolt does not reach the fully extended locking position, but (only) in the partially extended limit position or beyond.
  • the swing hook latch is (also) provided with a backup, z. B. via a (further) securing element, which z. B. may be formed as a safety lever.

  • These gear elements may be provided with corresponding teeth, so that the reduction gear is preferably designed as a gear transmission. In principle, however, other constructions and in particular transmission designs are possible.
  • a locking unit in particular an additional locking mechanism for an espagnolette lock, ensures a reliable and reliable self-locking based on a magnetic release.
  • the locking unit is characterized by an increased level of manipulation and burglary security, since (at least) two locking elements, namely on the one hand a latch bolt and the other a pivot hook latch are provided.
  • the reliability in the course of self-locking is optimized in particular by omitting a complete positive coupling between the latch bolt on the one hand and the lock chain on the other hand and thus a synchronous movement of this component.

If you compare the functional position in Fig. 4 (Limit position) with the functional position in Fig. 2a , it can be seen that the latch bolt 3 in the unlocked position after Fig. 2a is not backed up, since the latch bolt 3 can raise the lock chain on the edge 30 and the control lever 27 due to their contour. In contrast, the control lever 27 in the functional position Fig. 4 blocked in an attempt to push the latch bolt 3 back over the lock chain, so that a reliable backup of the latch bolt 3 already in or from this limit position after Fig. 4 is realized.
