Abstract:
Die Erfindung betrifft einen Türverschluss, insbesondere einer Schachttür eines Aufzuges, mit einem Gehäuse (2) und mit einem Riegel, der bezüglich einer Tür in eine Verriegelungsstellung und in eine Freigabestellung überführbar und der in dem Gehäuse (2) gelagert ist, wobei ein mit dem Riegel (3) zusammenwirkender Koppelungsmechanismus (4, 7) vorgesehen ist, der durch eine externe Einrichtung unter Überführung des Riegels (3) aus seiner Verriegelungsstellung in seine Freigabestellung betätigbar ist. Um unbefugten Personen einen Zugang zu dem Aufzugsschacht zu erschweren und bestehende gesetzliche Bestimmungen zu erfüllen, wird vorgeschlagen, eine mittelbar oder unmittelbar auf den Riegel (3) wirkende Sperreinrichtung (10) zur Sperrung des Riegels (3) in seiner Verriegelungsstellung vorzusehen. Ferner kann eine Steuerung (17) zur Ansteuerung der Sperreinrichtung (10) vorgesehen sein, wobei bei Normalbetrieb des Aufzuges die Sperreinrichtung (10) bei Empfang eines Signals eines zugeordneten Sensors (18) oder einer Kontrolleinrichtung in Entsperrstellung überführt wird, und wobei das Signal abgegeben wird, wenn eine Aufzugskabine (19) eines zugeordneten Aufzuges zumindest annähernd in bestimmungsgemäßer Position hinter der dem Türverschluss zugeordneten Schachttür angeordnet ist.
Abstract:
Die Erfindung betrifft ein selbstverriegelndes, elektromechanisches Panikschloss für eine Tür, mit einer federbelasteten, doppelschenkeligen Falle (4), einem in Längsrichtung eines Schlossgehäuses (1) verschiebbarem Glied (8), das mit einem Riegel (3) zusammenwirkt, sowie einem federbelasteten Steuerelement (5), welches das Glied (8) bei in das Schlossgehäuse (1) eingezogenem Riegel (3) in einer arretierten Stellung festsetzt, und einer Nuss (9), die einen das Glied (8) betätigenden Mitnehmer (21) aufweist, und dass zur Betätigung des Gliedes (8) zwei unabhängige Schließzylinder (18, 19) vorhanden sind, oder die Betätigung des Gliedes (8) elektrisch steuerbar ist, und dass die Stellungen einzelner sicherheitsrelevanter Bauteile über Sensoren (20, 30, 31, 32) erfasst werden und zu Steuerzwecken an eine Steuereinheit weitergeleitet werden.
Abstract:
A control method and apparatus for a door-locking mechanism which includes an electrically-released latch (21), to lock the door closed. A processing unit (10) sources first and second data streams each of a repeating string of binary data, the two strings being of the same bit length and bit rate, the processing unit also having two sensing inputs. A normally-open first switch is associated with the latch and connects the first data stream to the first sensing input other than when the latch is released, and a normally-open second switch is associated with the door and serves to connect the second data stream to the second sensing input so long as the door remains closed. A normally-closed third switch is also associated with the door and serves to link together the first and second sensing inputs when the door is not closed. The processing unit outputs a signal indicative of an error condition should the data stream which appears at either sensing input not be the expected stream.
Abstract:
The invention relates to an electrically unblockable release device (26) for doors, which is suitable for integrating into door frames of single doors or into the fixed leaf of double doors. Said release device (26) comprises a blocking lever (33) which acts on a catch (35) and is blocked or released by an armature (1) of an electromagnet. The release device (26) functions according to the closed-circuit current principle and the coil (2) of the electromagnet is embodied in such a way that the housing (15) thereof simultaneously forms an abutment for the U-shaped armature (1), in such a way that the armature (1) is guided beneath the coil (2).
Abstract:
Apparatus and methods for processing assets in a lockable container are disclosed. A decoupler receives information from the container or the asset in the container. The container may be associated with a security status, and the item may be associated with a processing status. The decoupler may move the container along a processing path in a sequence based on the security status of the container and/or the processing status of the asset. The decoupler may also lock or unlock the container while moving the container along the processing path. At least a portion of the processing path may be exposed to a magnetic field, which may lock or unlock the container and/o activate or deactivate a security tag associated with the container or the item. The decoupler may also write or read information to or from an RFID tag associated with the container and/or the asset. This information may be used in conjunction with benefit denial, audit, loss prevention, transaction management, and other similar systems.
Abstract:
The invention relates to a control method comprising the following steps: the user acts manually on a mechanical connection means for displacing auxiliary bolts towards a door-locking position; said action is detected by a sensor; and an electric motor is provided with a power supply for displacing blocking means into a position wherein they maintain the auxiliary bolts in the door-locking position thereof and for displacing the main bolt into a door-locking position. The invention also relates to a lock for carrying out said method.
Abstract:
A handle support mechanism is designed for attachment to a door lock, preferably the exterior of a mortise lock, that has two handles (50, 52) driven back to an initial position with a common return spring (62) after either handle (50, 52) is used. The support mechanism prevents the unused handle from drooping or rotating when the common return spring (62) is compressed as the opposite handle is turned. The support mechanism includes first and second friction discs (12, 14) trapped between the exterior of the mortise lock and the legs (16, 18) of a U-shaped spring bracket (10). The spring bracket (10) applies an inward spring pressure to prevent a friction disc (14, 16) and its corresponding handle (50, 52) from turning when the other handle is in use. The handle support mechanism improves visual appearance and is particularly suitable for retrofit installations, lever handle designs and mortise locks with independent switch sensors on the two handles that notify a monitoring system as to which handle was turned to open a monitored door.
Abstract:
The device comprises: a support structure (2) in which is defined an aperture (3) for the introduction in a predetermined direction of a door catch (4) connected to a door; a retainer member (10) movably mounted in the said structure (2) and having a seat (10) for receiving and retaining the door catch (4); a conditioning mechanism (11-13, 18, 25, 33) cooperating with the retainer member (10) and operable to assumea first condition in which it allows engagement of the door catch (4) with the retainer member (10) to retain the door in a closure position, and release of this coupling to allow opening of this door by application of a force on it; anda second condition in which the retainer member (10) is maintained in a locked position in which it is able to retain the door in a locked closure position; and a motorised control device (14-17) associated with the conditioning mechanism and electrically operable to cause passage of this mechanism from the first to the second condition and vice versa.
