Definitions

  • a locking element may be provided which can be actuated to automatically lock the locking unit in such a way that the latch bolt is automatically moved into the extended locking position.
  • the lock chain is held in the (neutral) unlocked position by a locking element, with the latch bolt being held in place by the lock chain.
  • a locking element whose (neutral) unlocking position is maintained in the partially extended unlocking position, wherein the locking element for automatic locking of the locking unit can be actuated (e.g. by a release magnet) in such a way that the locking element releases the lock chain (into the lowered locking position), so that the latch bolt is automatically moved into the extended locking position.
  • a locking unit refers in particular to an auxiliary lock of a rod lock or also to a central lock of a rod lock.
  • Auxiliary locks on the one hand and the lever-operated and key-operated central lock on the other are connected to each other via rods in a manner known per se, so that during locking, not only the central bolt, for example, arranged in the central lock, but also the locking elements (in particular, latch bolts) arranged in the auxiliary locks are typically disengaged.
  • the invention therefore 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, e.g., the latch bolt of the auxiliary lock, automatically move into the locked position when the door is closed.
  • the invention preferably relates to an embodiment with magnetic release, i.e., a release magnet is provided, which is preferably arranged in or on the (frame-side) strike plate.
  • a release magnet is provided, which is preferably arranged in or on the (frame-side) strike plate.
  • Such a locking unit is, for example, made from the DE 10 2008 011 551 A1 This is known.
  • the locking element is designed as a latch bolt, wherein the latch bolt is positively coupled to the lock chain via an intermediate lever.
  • Such an embodiment with magnetic release has proven highly successful in practice, but it is capable of further development. – This is where the invention comes in.
  • the secondary lock contains a locking element that is adjustable between a locked position and an unlocked position and automatically adjusts to the locked position when the lock or door is moved into the closed position.
  • a conventional latch is provided, which is slidably mounted between an extended position and a retracted position.
  • the latch of the secondary lock and the locking element of the secondary lock each have a frame-side recess into which the locking element of the secondary lock in the locked position, or the latch of the secondary lock in the extended position, engages when the lock is closed.
  • the locking element can, for example, be designed as a swing hook bolt.
  • the latch is a conventional, spring-loaded latch that assumes an extended position when unloaded. Consequently, when the door is closed, the latch runs with its slanted surface against the frame. and is thereby pressed towards its retracted position.
  • the latch of the secondary lock is coupled to a transmission element via a pivot lever such that when the handle of the main lock is actuated and the connecting rod is moved, the latch is moved into the retracted position against the force of the spring element. When the handle is released, the latch automatically returns to the extended position by the force of the spring element.
  • the position of the leaf in the area of the secondary lock is fixed so that the swing bolt, during the self-actuated locking mechanism triggered by the closing of the leaf, can move freely and without friction into the corresponding opening of the frame-side strike plate. Even partial retraction of the latch is sufficient to ensure the desired, defined position of the leaf.
  • the latch is therefore mounted in a way that decouples it from the automatic locking mechanism and can move into the extended position and fix the sash in the desired position even before the automatic locking of the locking element occurs or is triggered.
  • the EP 2 543 802 A2 A lock comprising a latch and a locking element, and at least one safety element that is adjustable between a locked and unlocked position by means of a magnetic attraction or repulsion force acting on the safety element and a frame-side release element.
  • the locking element is held in the unlocked position by this safety element.
  • the locking element is to be held in the unlocked position by the mechanism that is in the retracted position.
  • the latch must be held in the unlocked position.
  • the automatic locking mechanism is controlled by a dual locking system: first, the locking element in the unlocked position is held in the unlocked position by the locking element in the secured position; and second, the locking element in the unlocked position is held in the unlocked position by the latch in the retracted position.
  • the lock Starting from the open position of the door or similar, the lock employs a two-stage sequence control to trigger the automatic locking mechanism. This is intended to increase the reliability and security of the locking system and effectively prevent incorrect operation.
  • This lock primarily designed as a central lock within a multi-point locking system, uses a conventional spring-loaded latch.
  • EP 2 862 996 A2 A locking device for a door or window is known, comprising a main lock case and at least one secondary or auxiliary lock case, wherein the secondary lock case has a bolt that can be freely retracted in the unlocked position and at least one latch bolt can be moved beyond the latch position into a locked position by a latch spring.
  • the latch bolt forms a locking device for the drive rod, which is forced into a locked position by spring or gravity.
  • the self-release is achieved mechanically by special locking and release elements in or on the latch bolt.
  • EP 3 112 564 A1 discloses a locking unit according to the preamble of claim 1.
  • the invention is based on the technical problem of providing a locking unit for a door locking system, in particular for a To create a multi-point locking system with a drive rod mechanism that ensures reliable and functionally secure self-locking, e.g., through magnetic release, while simultaneously providing increased burglary protection.
  • the invention teaches, in a generic locking unit of the type described above, that in addition to the sliding latch bolt, a pivoting hook bolt (about an axis) is mounted in the lock housing, which in its pivoted locking position engages the locking strip or the strike plate or an element in or on the locking strip.
  • a pivoting hook bolt (about an axis) is mounted in the lock housing, which in its pivoted locking position engages the locking strip or the strike plate or an element in or on the locking strip.
  • the swing hook bolt is (forcedly) coupled to the lock chain in such a way that it can be moved with the lock chain from a swung-in unlocking position (i.e. lock chain in neutral unlocking position) to a swung-out locking position (i.e. lock chain in lowered locking position) and vice versa.
  • the invention is based on the initial understanding that a simple and tamper-proof self-locking mechanism, e.g., using magnetic [mechanisms], is possible. Triggering is advantageous when a locking element is integrated into the locking unit, either blocking or releasing the self-moving lock chain within the lock case. This eliminates the need for complex mechanical release mechanisms, such as those integrated into a latch bolt or implemented via separate release levers in prior art designs.
  • the magnetic self-release offers a high level of tamper resistance, as manipulation by purely mechanical means is impossible. Building upon these considerations, tamper resistance and burglary protection are further enhanced by incorporating a pivoting hook bolt in addition to the sliding latch bolt.
  • This pivoting hook bolt is not combined with a simple latch bolt, but rather with another locking element—a latch bolt—ensuring a particularly high level of security through the combination of these two locking elements.
  • these locking processes are not realized simultaneously, but with a time delay, because the swing hook bolt is only extended once the latch bolt has already been inserted into the strike plate to a certain extent. This ensures that the latch bolt not only locks the door but also pre-centers it, allowing the swing hook bolt to reliably engage the strike plate and connect behind it or any element attached to or within it.
  • this pre-centering is not achieved with a simple spring-loaded latch bolt, but with a latch bolt that can assume not only a defined fully extended (anti-return) locking position, but also a defined partially extended (non-anti-return) unlocking position.
  • this is demonstrated in the Within the framework of the invention, this is achieved in particular by the fact that the latch bolt is not fully positively engaged or forcibly coupled to the lock chain, so that a certain degree of kinematics of the latch bolt is possible even independently of the movement or position of the lock chain.
  • a coupling between the lock chain and the latch bolt is preferably implemented only such that the latch bolt can be retracted from the (fully extended) locked position or from the (partially extended unlocked position) to the fully retracted open position by moving the lock chain (in particular by lifting the lock chain).
  • a coupling between the lock chain on the one hand and the latch bolt on the other hand is preferably implemented such that the latch bolt is held in the partially extended unlocked position by the lock chain and the latch lever.
  • the coupling of the latch bolt with the lock chain is therefore particularly preferably limited to a coupling in the unlocking or opening direction, i.e., during the lifting of the lock chain.
  • the lock chain is held by the latch bolt after release by the locking element (e.g. as a result of a magnetic release), i.e. blocked against lowering, until the spring-loaded latch bolt reaches the partially extended limit position.
  • the locking element e.g. as a result of a magnetic release
  • Such a blocking of the lock chain, extending to the partially extended limit position of the latch bolt, can be achieved through a suitable design of both the lock chain and the latch bolt, so that the latch bolt directly blocks the lock chain.
  • the operative connection between the latch bolt and the lock chain during blocking is achieved via an additional element, e.g., an additional control lever, through which the lock chain is operatively connected to the latch bolt. If the lock chain is released, e.g., after a magnetic release by the locking element, it does not immediately lower completely, but is held by the control lever until the spring-loaded latch bolt reaches its limit position.
  • the latch bolt is thus operatively connected to the lock chain via two elements or two levers, namely on the one hand the latch lever, which is particularly important in the course of unlocking and consequently in the course of raising the lock chain, and on the other hand via the control lever, which is particularly important in the course of lowering the lock chain after an automatic release.
  • the control lever can also be equipped as a pivoting lever, which is, for example, mounted to pivot about a horizontal axis.
  • This control lever itself is not spring-loaded.
  • the latch lever itself not to be directly spring-loaded.
  • the latch bolt is directly spring-loaded, for example by a torsion spring or a comparable spring element that acts on the latch bolt in the extension direction.
  • the lock chain can be directly spring-loaded for gravity assistance; that is, the lock chain is not only forced into the locked position and consequently into the lowered position by gravity, but also by the force of an additional spring, e.g., a torsion spring.
  • the control lever preferably has an (end-side) control cam that acts between the latch bolt on one side and the lock chain on the other.
  • This control cam can be actuated by the latch bolt, for example, by an actuating surface or edge of the latch bolt, and can then act on the lock chain, lifting it.
  • the lock chain itself can have a corresponding control contour upon which the control lever, for example, its control cam, acts. The control contour is designed such that the The described blocking function of the lock chain is ensured until the spring-loaded latch bolt reaches the partially extended limit position.
  • the burglary and manipulation resistance of the locking unit is increased by providing a latch bolt on the one hand and a swing bolt on the other, wherein the latch bolt does not merely perform a latch function, but is itself designed as a locking element.
  • the latch bolt is doubly or two-stage secured against being pushed back, not only in the (fully) extended locking position, but also (already) in or from the partially extended limit position, from which point the swing hook bolt also extends.
  • an additional locking element can be provided for the push-back protection in the fully extended locking position, which prevents the latch bolt from being pushed back in this locking position.
  • the latch bolt is also (already) pushed back when the latch bolt has been extended to the limit position (or beyond).
  • An additional locking lever can be provided for this purpose.
  • this push-back protection in the limit position can be implemented using the control lever already described in conjunction with the lock chain.
  • a two-stage anti-return mechanism is implemented for both the locked and limit positions, preferably by the interaction of the latch bolt with the lock chain, e.g., with the interposition of one or more locking elements.
  • the locking system is characterized by special tamper-evident features and Burglar resistance is ensured because the latch bolt is secured against being pushed back even if it does not reach the fully extended locking position, but (only) the partially extended limit position or beyond.
  • the swing hook bolt is (also) equipped with a push-back safety device, e.g., via a (further) locking element, which can be designed, for example, as a locking lever.
  • a push-back safety device e.g., via a (further) locking element, which can be designed, for example, as a locking lever.
  • the additional pivoting hook bolt which, for example, pivots from the unlocked position to the locked position and vice versa during the movement of the lock chain, so that the pivoting hook bolt is preferably positively coupled to the lock chain in both directions of action.
  • the lock chain has an actuating section, e.g., an actuating arm or actuating projection, which is coupled to the pivoting hook bolt itself or to an (additional) actuating lever for the pivoting hook bolt.
  • This actuating lever can itself be designed as a pivotable or rotatable lever.
  • the lock chain is coupled to the pivoting hook bolt via a transmission, preferably a reduction gear, so that pivoting of the pivoting hook bolt, e.g., by a pivot angle of 90°, is enabled via a relatively small stroke of the lock chain.

  • a locking unit in particular an auxiliary locking mechanism for a bolt lock, which ensures reliable and functionally secure self-locking, preferably based on a magnetic release.
  • the locking unit is characterized by an increased degree of tamper and burglary resistance, since (at least) two locking elements are provided: a latch bolt and a swing bolt.
  • the functional reliability of the self-locking mechanism is optimized, in particular, by eliminating the need for a fully forced coupling between the latch bolt and the lock chain, and thus the synchronous movement of these components.
  • the kinematics of the self-locking mechanism are predetermined with regard to the timing sequence, so that the swing bolt only fully extends once the latch bolt has extended sufficiently and pre-centered the door.
  • the invention also relates to a rod lock with at least one central lock and at least one additional locking mechanism, wherein, in particular, such an additional locking mechanism is designed in the manner described. Consequently, not only is the locking unit itself protected, but also a rod lock with such a locking unit. Furthermore, a locking assembly is also protected, which consists, on the one hand, of a locking unit (or a rod lock with several locking units) and, on the other hand, of a locking bar associated with the locking unit, wherein the release magnet is arranged in or on this locking bar.
