Definitions

  • the invention relates to a high-security lock comprising a locking mechanism having a locking element, a spring loading and a holding device, wherein the locking element between a "locked” position and an “unlocked” position is movable and the spring action acts in such a way on the locking mechanism, in that the locking element is moved from the "unlocked” position to the "locked” position and wherein the retaining device is functionally independent of the spring loading for maintaining the positioning of the locking element in the "locked” position, the retaining device having a permanent magnet , which holds the locking mechanism in the position in which the locking element is in the "locked” position, and wherein the holding device comprises a locking latch, which is designed to block the locking element in the "locked” position, and wherein the permanent magnet is arranged on the locking latch.
  • Locks whose mechanics are independent of the spring loading to maintain the positioning of the locking element in the "locked” position and in which a permanent magnet holds the locking mechanism in the position in which the locking element is in the "locked” position are basically known in the art.
  • this describes US 5,755,126 a lock for a freight container in which the locking element is held in the "locked” position by both a spring and a permanent magnet.
  • EP 1 669 524 A1 a lock is described in which a locking latch is pivoted by the repulsion of two magnets in a receptacle on the locking element, that this can not be moved back.
  • High-security lock Locks and in particular door locks for high-security applications are characterized by high strength values as well as high functional reliability and low manipulability. Typical applications of such high security locks lie, for example, in high-security areas, on the catchment area, etc.
  • a typical high-security lock for example, from the DE 38 75 642 T2 known.
  • the known high-security locks tensile, compressive, spiral or torsion springs, which act on the locking element, which is for example a bolt, in such a way that it is pressed by the spring elements in the "locked” position to a Locking the high security lock to ensure.
  • the "locked” position is thus to be understood as meaning a position of the locking element in which it locks a door.
  • the high security lock is usually embedded in a door leaf, wherein the locking element for locking the door, that protrudes in its "locked” position, on the door leaf side cuff and in a tzargen worne recess, which is surrounded for example by a strike plate projects.
  • a high-security lock and in particular an electromagnetically operable high-security lock that this can be operated both in the working current and in the quiescent current principle.
  • the door With the working current principle, the door is unlocked during activation and can therefore be opened upon contact. In contrast, the door is always locked in the quiescent current principle, as long as the power is turned on. If the power is interrupted when a contact is made or due to a power failure, the door is unlocked and can thus be opened.
  • a permanent energization of an actuator which usually represents a Hubmagnetspule necessary for controlling the locking state thus depending on the locking state for certain periods.
  • a high-security lock which operates in the working current principle, must be energized, for example, for unlocking. Accordingly, a permanent current supply is required for locking and maintaining the locking state in high-security locks in quiescent current execution.
  • the energization causes a total warming, which both the castle as well as the door leaf warmed up. In individual cases, this heat development can even go so far that, in particular in the case of wooden doors, ignition-critical temperatures can be achieved. This risk also contradicts the high-security idea of a high-security lock.
  • the functional integrity of the known high-security locks thus depends entirely on the functionality of the spring elements and a usually electromagnetic trip unit.
  • the electromagnetic trip unit is ultimately the component which triggers an unlocking or locking the high-security lock by energizing. Typically, this is a solenoid with a coil.
  • the invention is therefore based on the object to provide a high-security lock, which has a particularly high reliability.
  • This relates in particular to ensuring the functional integrity of the locking element, regardless of whether the spring element, by which the locking element is acted upon, is functional. But this also applies to a particularly high security against manipulation and a reduced heat development of the high-security lock.
  • the core idea of the invention is to provide a high-security lock with at least one redundancy function.
  • redundancy function in the context of the invention is the additional presence of functionally same acting means or devices to understand, so that proper functioning of the high security lock even in case of failure of an element, such as the breakage of a spring element, by the redundant means or redundant existing Device is guaranteed.
  • a locking operation of a generic high-security lock usually comprises at least the steps a) actuating an electromagnetic trip unit, b) moving a locking element from an "unlocked” position to a “locked” position and c) stabilizing the locking element in the "locked” position.
  • An inventive high security lock is thus intended for locking / locking objects and in particular doors.
  • the high-security lock for example, embedded in a door leaf, which is surrounded by a door frame. Door frame side, a recess is provided, in which a locking element, such as a bolt which protrudes from the door leaf side high security lock in the "locked” position, can protrude.
  • the redundancy function increases the locking security of a high-security lock insofar as failing components are buffered by parallel components or mechanisms in their functioning. This may, for example, be an additional stabilization of the locking element in the "locked” position.
  • the use of a magnet and more particularly of a permanent magnet has proven to be particularly suitable, since this in addition to the high functional reliability has a comparatively small footprint and thus the cramped space conditions in high security locks particularly well. It is inventively provided that the magnet and in particular the permanent magnet is arranged in the high security lock, that it then interacts to stabilize the locking element in the "locked” position with a magnetic material when the locking element in the "locked” position is.
  • the magnet and in particular the permanent magnet does not act directly on the locking element itself or is arranged on the locking element itself, but acts, for example, on parts of the locking element positioning locking mechanism or is arranged on this.
  • a gravity-dependent stabilization of the locking element in the "locked” position is also provided according to the invention.
  • a stabilization of the locking element which uses the force of gravity as a driving force to bring the locking element in the "locked” position and / or keep.
  • This includes, for example, the use of a pivoting bolt, which is arranged in its center of gravity on the high security lock, that it pivots itself in a position, as far as no counteracting spring forces or by other means acting on the locking element forces the free pivoting movement of the pivot bolt oppose, in the pivot bolt stabilizes the locking element in the "locked” position.
  • the pivot lever can act directly or indirectly to the locking element.
  • a positioning mechanism of the locking element in such a way that the locking mechanism is in functional connection with the locking element and the locking mechanism or parts of the locking mechanism, the locking element gravity-dependent in the "locked" - Stabilize position.
  • the method for locking a high-security lock may include switching to a holding function and in particular an electromagnetically controllable holding function for locking the bolt.
  • the holding function is preferably designed as an electromagnetically controllable holding function.
  • the hold function is a function that detects the positioning of the lock member in the "unlocked” position and / or in the "locked” position, disengaged from the trip unit.
  • the normally electromagnetically controllable tripping unit of the high security lock is thus relieved by the holding function and in particular by the electromagnetically controllable holding function after a triggered by the trip unit method of the locking element, for example, from the "unlocked" position in the "locked” position or vice versa.
  • This relief may include switching the holding function to the trip unit when the latch member has moved the latch to the "locked” position and / or the "unlocked” position. But it is also possible that the electromagnetic trip unit is used exclusively for a method of the locking element between the "unlocked” position and the "locked” position and the determination of the locking element is achieved solely by the holding function. In order to coordinate this process sequence, control means may also be present which control the switching processes of the holding function and the tripping unit with respect to one another.
  • the redundancy function can also include a coupling of a fully mechanically actuated locking mechanism. It is thus possible according to the invention, regardless of the electromagnetic trip unit to unlock the high security lock via a locking mechanism and / or to lock. This can be done for example via a pawl or via a key-operated mechanism.
  • a locking mechanism provided in the operating mechanism of the high-security lock, which can optionally be engaged for locking and / or unlocking the high security lock.
  • the locking mechanism is accordingly designed so that an operation of the high-security lock is normally possible via the electromagnetic trip unit.
  • the fully mechanized actuated locking mechanism which thus allows parallel to the electromagnetic trip unit unlocking or locking the high security lock, be connected by a Einkupplungsvorgang.
  • This function thus allows independent from the electromagnetic trip unit locking and / or unlocking the high security lock.
  • the training of this fully mechanically actuated locking mechanism as mechanical locking function has been found to be particularly preferred.
  • the engagement of the fully mechanically actuated locking mechanism is thus preferably designed so that the position of the fully mechanically actuated locking mechanism of the function of the electromagnetic trip unit is functionally superior.
  • a triggered by the fully mechanized actuated locking mechanism locking the high-security lock accordingly ensures the positioning of the locking element in the "locked" position, regardless of the positioning or activation / deactivation of the electromagnetic trip unit.
  • a high security lock comprising a holding device, which is functionally independent of the spring action to maintain the positioning of the locking element in the "locked” position.
  • a holding device is thus provided, which ensures a determination of the positioning of the locking element in the "locked” position even if the spring loading the locking element by spring break or the like can no longer hold the Verriegeglungselement in the "locked” position.
  • the holding device is thus to ensure the positioning of the locking element redundant to spring loading of the locking element. This is particularly advantageous in the high-security sector, where the guarantee of the closure state of a high-security lock is of particular importance.
  • a holding device according to the invention with a magnet and in particular with a permanent magnet which holds the locking mechanism in the position in which the locking element is in the "locked” position, is particularly safe.
  • the use of a permanent magnet has the advantage that it allows a reversible detection of the locking mechanism regardless of a power supply or spring loading. The locking element is thus simultaneously kept independent of the spring action in the "locked” position and can also, after overcoming the caused by the magnet holding force, are moved to the "unlocked” position.
  • a permanent magnet is advantageous in this context, since the space requirements of a permanent magnet are comparatively low, so that the holding device according to the invention can be relatively easily integrated into the confined spatial conditions of a high-security lock.
  • the holding device comprises a locking catch which is designed to block the locking element in the "locked” position, wherein the permanent magnet is arranged on the locking catch.
  • the locking latch is part of the locking mechanism and can be moved at least between a position blocking the locking element in the "locked” position and a position releasing the locking element in the "locked” position. If the locking catch locks the locking element in the "locked” position, then the locking element can not be moved to the "unlocked” position.
  • By an arrangement of the permanent magnet on the locking latch advantageously no additional component is required, which carries the permanent magnet.
  • the magnetic material is arranged so that the arranged on the locking latch permanent magnet in the position in which it locks the latch in the "locked" position, can interact with the magnetic material.
  • An interaction between the permanent magnet and the magnetic material can be achieved for example by a direct abutment of the permanent magnet to the magnetic material.
  • the two components can also be so far apart from each other for the interaction that, although there is no longer direct contact, the permanent magnet can still interact with the magnetic material. Accordingly, for example, non-magnetic spacers or even air or an air gap between the two components may be provided in the interactive state.
  • a lock housing comprising the magnetic material is provided for holding the locking mechanism in the position in the locking element is in the "locked" position is formed by an interaction with the permanent magnet.
  • the magnetic material is preferably a metal having magnetic properties, which is arranged, for example, on the lock housing or is formed by the lock housing itself. The latter embodiment has the advantage that no additional component for the provision of the magnetic material must be present.
  • the magnetic material is further preferably arranged in the lock housing interior, so that the holding device is completely surrounded by the lock housing and thus is particularly well protected against external influences.
  • the holding device and in particular the locking latch comprises a two-armed pivoting lever, one arm of which is a locking lever operatively connected to the locking element in such a way that the locking element can be locked by the locking lever in the "locked” position, and the other arm of which is a holding lever formed to maintain the positioning of the locking member in the "locked” position regardless of the spring loading.
  • the above embodiment is also suitable according to the invention for combination with a permanent magnet.
  • the permanent magnet is for this purpose connected to the retaining lever of the locking latch, which abuts in the "locked" position of the locking element against a housing-side stop area with the magnetic material in such a way that the permanent magnet interacts with the magnetic material. A defect of the spring action thus does not lead to an unwanted unlocking of the high security lock.
  • the pivot lever is additionally held in the locking member locking position by the permanent magnet interacting with the magnetic material. This embodiment is thus particularly safe in terms of maintaining the positioning of the locking element in the "locked" position.
  • the two-armed pivoting lever is preferably formed so that the locking lever and the retaining lever are arranged substantially orthogonal to each other and the retaining lever in the position in which it holds the locking mechanism in the position in which the locking element is in the "locked" position, runs parallel to a security lock outwardly bounding and an exit recess for the locking element opposite rear wall.
  • the housing rear wall can be used as a flat stop area for the retaining lever, so that no additional components for forming the stop area are necessary.
  • the mutually perpendicular arrangement of the holding lever and the locking lever requires a particularly favorable power dissipation of forwarded to the locking element and the locking mechanism forces. Even with the application of drastic manipulation attempts, the functional integrity of the high-security lock is ensured particularly reliably in this embodiment.
  • a permanent magnet may lead to remanence, i. a persistent magnetization of the magnetic material caused by the permanent magnet.
  • a non-magnetic material and in particular an air gap between the permanent magnet and the permanent magnet interacting material for holding the locking mechanism in the position in which the locking element is in the "locked" position is arranged.
  • a preferred embodiment of the invention is characterized in that it comprises a holding device and in particular an electromagnetically controlled holding device, which is designed in such a way that it can be switched into a "lock" position in which it determines the position of the Locking mechanism locked.
  • the cross-redundancy idea of the invention relates in this aspect of the invention, the discharge of the locking mechanism.
  • This usually has an electromagnetic trip unit comprising, for example, a coil and a movable in relation to the coil lifting magnet.
  • the electromagnetically controlled holding device relieves the locking mechanism and in particular the electromagnetic trip unit while maintaining the positioning of the locking element.
  • it is possible in this way that the locking mechanism in the "locked” position or the "unlocked” position is locked even with a defective locking mechanism and in particular a defective electromagnetic trip unit.
  • an electromagnetic trip unit it is possible to design this unit smaller than high-security locks known from the prior art.
  • the associated with the operation of the electromagnetic trip unit heat generation can thus be effectively reduced, so that in particular the use of wooden doors can be effectively prevented from reaching inflammation critical temperatures.
  • the electromagnetically controlled holding device can be designed so that it acts directly on the locking element. Alternatively, it is also possible to provide an indirect effect, in particular via the locking mechanism on the locking element.
  • a holding device comprising preferably an electromagnetically controllable locking armature, which is switchable between the "lock” position and a “release” position in which the locking mechanism is released, has proven to be particularly advantageous.
  • the Sperranker may for example be a lever which locks the locking mechanism in the "lock” position and thereby locks the locking element in a predetermined position.
  • the locking mechanism also has the use of an electromagnetic trip unit with a coil and a solenoid on which a locking means is arranged, which is formed in such a way that the locking armature is to lock the locking mechanism with the locking means in engagement, as particularly favorable proved.
  • the holding device thus acts directly on the part of the locking mechanism, via which a remote-controlled release of the high-security lock is possible.
  • a latching means is provided, which may be according to the invention, for example, latching lugs, projections, etc., act whose common feature is the possibility to allow engagement of the locking armature to lock the locking mechanism.

  • the control unit thus enables activation of the holding device to be used only when the locking mechanism has been moved by the release unit into the position to be blocked by the holding device.
  • This embodiment combines several advantages. On the one hand, it is ensured that the holding device is triggered exclusively to block the locking mechanism. In this way, the heat development caused by the electromagnetic holding device can be further reduced. On the other hand, it is also ensured that the functional sequence of the triggering device or the locking mechanism is synchronized with the operating state of the holding device.
  • such a control of the high-security lock is to be understood that the holding device is activated only if a blocking by the holding device is possible or desired, so for example after the locking element by the electromagnetic trip unit from the "locked" position in the "unlocked” position or vice versa.
  • the high-security lock is designed in the closed-circuit principle, wherein the holding device is designed in such a way that it locks in its "locked” position the bolt in the "locked” position.
  • This blocking can be achieved by a direct action of the holding device on the locking element or by acting on the holding device on the locking mechanism.

  • Characterized the locking latch 6 is pivoted in the direction of arrow C, which ultimately the latch 2 is pivoted in the direction of arrow D for unlocking the high-security lock 1 in the lock housing 7. If the energization and thus the activation of the electromagnetic trip unit 12 is stopped, the bolt again pivots out of the lock housing 7 in the direction of arrow D 'and locks a door equipped with a high-security lock 1.
  • the locking latch 6 is correspondingly arranged on the high-security lock 1 in such a way that it pivots into the position in which the bolt 2 is in the "locked” position, ie the locking latch 6 tends to pivot in the direction of the arrow C '.
  • the permanent magnet 4 ultimately stabilizes the latch 2 in its "locked” position. This is especially true in the FIGS. 2a and 2b clear.
  • the locking latch 6 moves to lock the high security lock 1 in the direction of arrow C 'and strikes the flat and the inner surface of the fortress 20 opposite rear wall of the lock housing 7.
  • the permanent magnet 4 is designed to interact with the magnetic material 5, so that the locking latch 6 is pulled toward the rear wall of the lock housing 7 or in the direction of the arrow C '.

  • the locking arm 14 By pivoting the locking arm 14 in the direction of arrow E of the locking arm pivots to this locking means 17 and engages behind the locking means (the rear engagement is with the dashed circle in Fig. 4f highlighted), so that the solenoid 16 is no longer in the direction of arrow A 'according to FIG. 4b can be moved.
  • the barrier arm 14 is then in his "lock” position.
  • the solenoid 16 of the electromagnetic trip unit 17 is thus mechanically blocked by the locking arm 14.
  • a permanent maintenance of the positioning of the lifting magnet 16 by a continuous current of the electromagnetic trip unit 12 is thus no longer necessary to maintain the unlocked state of the locking mechanism.
  • the electromagnetically controlled holding device 13 thus relieves the electromagnetic trip unit 12.

  • the movements of the locking mechanism are essentially comparable to the high security lock 1 and are in the FIGS. 5a and 5b illustrated in more detail.
  • the essential difference of the high-security lock 1 'to the high-security lock 1 is that the solenoid 16' spring-loaded (spring 25) and energization of the electromagnetic trip unit 12 'in the direction of arrow A' linear displacement of the solenoid, so the locking mechanism out triggers.
  • FIG. 5a is the trip unit 12 'thus activated or energized and according to FIG. 5b deactivated or de-energized.
  • FIGS. 5c to 5f is the locking means 17 thus also for locking the locking mechanism in the locked state of the high security lock 1 'formed.
  • the holding device 15 engages to lock the lifting magnet 16 'below the locking means 17, as indicated by the dashed circle in Fig. 5e is highlighted.
  • FIGS. 6a and 6b relate to the high-security lock 1, which is executed in the working current principle.
  • the thrust element 18 is designed for linear guidance along the forepan 20 opposite rear wall of the lock housing 7.
  • the thrust element 18 has two opposite legs 27 and 28, which are connected via a connecting element, which runs essentially parallel to the rear wall of the lock housing 7.
  • the first leg 27 of the thrust element 18 has a contact region against which an actuatable by the cylinder lock 24 Verschubstoff 26 can strike.
  • the Verschubstoff 26 is pivotable in the direction of arrow F against the first leg 27, wherein a pivoting of the pushing means 26 causes a linear movement in the direction of arrow G of the thrust element 18.
  • the second leg 28 of the thrust element 18 limits on the one hand the extent of movement of the lifting magnet 16 of the trip unit 12 in the direction of arrow A.
  • the second leg 28 in the manner designed such that a shift in the direction of arrow G of the thrust element 18, the lifting magnet 16 regardless of energization or Brockbestromung the electromagnetic trip unit 12 causes in the direction of arrow A '.
  • a locking of the high security lock 1 is thus independent of the functional integrity of the electromagnetic trip unit 12 and the spring elements 3a and 3b and can be triggered fully mechanically. If the high-security lock is fully mechanically locked via the coupling 18, it is not possible to release it via the release unit 12. In this way, therefore, a lock of the high-security lock 1 in emergency situations in which, for example, a power failure occurs, possible.
