Definitions

  • the invention relates to a locking or locking device for a wing system, in particular door system, ie a device which is adapted to hold at least one wing of the wing system in at least one predetermined opening position as a locking position and thus to prevent movement and in unlocking this at least one Release wings so that it can be moved again.
  • the lock locks when energized and unlocked in the absence of energization.
  • escape route doors which in an emergency, ie in the absence of electrical power supply, release an escape route and thus have to cancel a lock of the respective door leaf.
  • the lock unlocks when energized and locked in the absence of energization.
  • security doors which must be kept securely closed in an emergency. Such locks must therefore be supplied with electrical energy for a considerable period of time in order to lock or unlock the respective wing. This leads to an enormous expenditure of energy and thus to high energy costs.
  • the object of the invention is to provide a rempligelverriegelungs- or -feststellvorraum, which at least reduces the disadvantages of the prior art.
  • a device is set up to lock or determine a wing of a wing system in a predetermined opening position, ie to prevent it from moving.
  • the device has a locking element and an element to be locked.
  • the locking element is set in the locking position as one of two working positions to lock the locking member or to prevent a movement in the unlocked position as the other of the two working positions. In unlocking position, however, the locking element releases the element to be locked with respect to its movement.
  • One of these two elements is operatively connected to the wing so that it is moved along with a movement of the wing of this. This one element may for example be attached to the wing.
  • an operative connection for example with a slider is possible, which is an example of part of a slide linkage, with which a trained as a door swing wing of a swing door system is operatively connected as wing system in a known manner.
  • the locking element is provided with a bistable electromagnet.
  • the electromagnet has an element which is in permanent magnetic interaction with an armature such that the armature is held in a respective one of the two working positions, that is, for example in the locking position, by this one element with a predetermined holding force (magnetic).
  • this element can be used as a permanent magnet be formed, wherein the armature is formed of magnetizable material.
  • the armature is designed as a permanent magnet and said element is formed of magnetizable material. In both cases, no current is required to hold the armature in unlocked or locked position.
  • the electromagnet also has a return mechanism which is adapted to apply to the armature a restoring force in the direction of the other of the two working positions, that is, for example, the unlocked position. The return mechanism thus acts counter to the effective direction of the magnetic retaining mechanism '. This has enormous advantages in terms of the energy requirement of the lock according to the invention.
  • the electromagnet has a coil arrangement.
  • the coil arrangement can be supplied with current in accordance with a first switching mode, ie it reduces or even completely eliminates the holding force such that the restoring force is greater than a resulting residual holding force of the one element with respect to the armature.
  • the electromagnet can no longer hold the armature against the force of the return mechanism, and the return mechanism moves the armature automatically from the respective one of the two working positions to the other working position and thus switches the device between the working positions.
  • the current supply causes the armature to be moved away from the associated working position counter to the effect of the respectively opposing magnetic counter-element.
  • the locking or locking element is adapted to be used in a fixed position in such a door system stationary. This makes it possible to integrate the lock in any door system having a rail.
  • the coil assembly according to a logically second, opposite switching mode is energized such that it exerts on the armature a force sufficient to move this against the restoring force in the respective of the two working positions (back).
  • the current supply causes the armature to be moved in the direction of the magnetic counter element.
  • the return mechanism is realized or at least supported by this energization.
  • the armature between the aforementioned two working positions along a predetermined path of movement is further preferably translationally movable. This simplifies the structure of the lock to the effect that no additional force or movement deflections are necessary to bring the armature in locked or unlocked position. This allows the use, for example, single-leaf, manually operated sliding sash systems such as sliding window systems, folding door systems, partitions and the like.
  • the other, ie to be locked or (self) locking element is preferably arranged to be inserted into the same or another rail in or along and thus guided by this. This is on the one hand a safe operation of the lock possible.
  • these elements of the latch apart from the mutual locking engagement, do not have to meet any other criteria regarding their travel or stability. The path of movement of the element to be locked or locked is thus defined and ensured by the associated profile rail. If the profile rail runs straight, the element to be locked or locked is translationally movable.
  • the lock may further comprise a holding part to which the aforementioned stationary insertable element is fixedly mounted. Further includes they are a clamping part, wherein the clamping part and holding part receive the stationary insertable element between them and form two halves of a housing of the stationary insertable element. This provides mechanical protection and possibly protection against contamination of this element. In addition, it can be freed from stability tasks and optimized for the locking function.
  • the lock preferably has clamping means, by means of which the stationary insertable element is clamped in the rail via the clamping or holding part.
  • the deadlock has the advantage of being able to fix the stationary element at any position in the rail without having to edit the rail. This allows in particular a very simple retrofitting and adjustability of existing systems with regard to the installation position of the lock in the rail and thus the opening position of the or the associated wings, in which the lock locks the wing or the.
  • the clamping means advantageously comprise at least one screw which is supported on a first inner surface of the profile rail. It is also screwed to the clamping or holding part such that the clamping or holding part is pressed during rotation of the screw in a Verklemm-direction of rotation against a second inner surface of the rail, that the stationary element is clamped in the rail. D. h the clamping action is effected by the screw presses with one end against the first inner surface of the profile part and the thus screwed clamping or holding part is pressed against a corresponding second inner surface of the rail and thereby clamped.
  • the lock according to the invention is preferably further configured to release the element to be locked when the lock on a Force acting against the retaining means of the locking element, which is greater than a predetermined maximum holding force of the locking element.
  • the lock allows the violent unlocking of the relevant wing and thus has an overload protection that helps prevent damage to the wing system or the lock itself.
  • the latch according to the invention preferably further comprises a self-sufficient power supply, which is electrically coupled to the locking element.
  • a self-sufficient power supply which is electrically coupled to the locking element.
  • the power supply is preferably also set up to be used fixedly in one, preferably the same, rail.
  • the entire lock can be used as a compact unit in a single rail.
  • Only the coupling with a locking control, for example in the form of an emergency opening switch still has to be made. Ie. during assembly, there is only a single part, namely the rail, drilled for the mounting holes if necessary Need to become.
  • the rail must not be edited, namely, if it is glued, for example, on a support body as a door frame.
  • the power supply is fixed to the stationary insertable element.
  • the power supply itself must be designed only to be used in the rail, but not necessarily locked in this self. This is done via the stationary insertable part.
  • the power supply may be formed, for example, as a simple battery pack, which is glued to the stationary element, for example.
  • the locking element preferably has a plunger which extends away from the armature and the electromagnet substantially along the path of movement and, in the locked position, brings at least one locking part of the locking element into a position in which the at least one locking part engages with a corresponding locking part of the locking element Element is in lock engageable or stands. Ie. not the anchor but an operatively connected locking member causes the lock. This makes it possible to optimize the armature or plunger with respect to the locking part and the magnetic interaction with the coil assembly and the magnet out. Stability criteria with respect to the locking engagement with the element to be locked are not or hardly observed.
  • the plunger preferably comprises two rod sections.
  • One of the two bar sections is operatively connected to the armature such that its movement is transferred to that one bar section. It is also guided on or in the other rod portion relative to this movable. Ie. the movement or current position of the anchor does not in all circumstances cause the locking effect to occur. It is possible, despite the locking position of the armature to effect a (forced) unlocking.
  • the rod section remote from the armature runs pointedly at its end facing away from the armature.
  • the latch further includes a return member configured to urge the rod-removed portion toward the tapered end.
  • Each rod section preferably has a stop in each case. Between the thus two relatively movable stops is used as a restoring element biased a compression spring. This is a particularly easy way to realize the overload function.
  • the locking element advantageously further has a limit to the movement of the rod sections relative to one another. This serves for operational safety, since the rod sections can only move in a predefined manner which does not impair operation.
  • the at least one locking part of the locking element can be formed by means of a pivoting arm.
  • the pivot arm is pivoted due to the tapered end of the armature remote rod portion upon movement of this rod portion in the direction of pivot arm in the locking position. It has at its end remote from its pivot axis on a locking portion which is in locking position with the corresponding locking portion of the locked element in locking engagement.
  • This is a particularly simple and powerful very effective solution for overload-protected locking.
  • the swivel arm facing, thus acting as a starting slope surface said rod portion causes an adaptable to the particular application force transmission between the magnetic holding force of the magnet with respect to the armature and the locking member.
  • the aforementioned profile rail may be formed as a slide rail of a slide linkage. It can also be designed as a support, (floor) guide and / or support rail of the relevant wing or wing system or include these. Ie. Despite the locking forces to be applied, the lock can be made so compact or with such small dimensions that it can be used in almost any rail.
  • the electromagnet can have a plurality of mutually independent coils or windings, depending on how the interlocking device according to the invention is to be operated. Ie. the coils or windings can be arranged and formed in accordance with the desired mode of operation of the latch.
  • This allows, for example, a redundant and thus fail-safe operation of the electromagnet and thus the device of the invention as a whole by one or more Coil / n or winding / s is or are available as a replacement for one / several other coil (s) or winding (s).
  • different locking or unlocking forces can be generated or adjusted on the electromagnet, which increases the possible uses of the device.
  • the device is thus universally applicable; Less trained, standardized electromagnets are possible in training, which helps reduce costs. In addition, it is thereby possible to achieve a mode of operation, for example including Vorlastüberwindung.
  • Suitable, provided with such a locking wing systems are in particular all sliding sash systems such as sliding door, Schiebeful-, partition walls and further revolving door systems with movable drum walls and swing door systems preferably with Gleitgestnaturee.
  • the lock can also be used on a door without slide linkage by the lock is fastened with a holder as a rail on the aforementioned support body such as a door frame, wall or the like.
