Abstract

The arrangement has a locking bolt (4a) that can be moved linearly by an electric motor (2). A threaded sleeve (5) with an external thread mounted on the opposite end of the driven shaft from the motor interacts with an internally threaded nut (4) linearly movable in a housing (1) enclosing the motor and nut and connected to the locking bolt via an opening in the housing. Coil springs (3,3a) are arranged between the housing and nut to enclose the bolt within the housing and between the nut and motor to enclose the drive shaft.

Description

Die Erfindung betrifft eine elektromotorische Blockiervorrichtung, insbesondere für verschließbare Anlage, wobei ein Sperrbolzen vorgesehen ist, der durch einen Elektromotor linear bewegbar ist.The invention relates to an electromotive locking device, in particular for lockable system, wherein a locking pin is provided by an electric motor is linearly movable.

In elektronischen Schloß-Schlüssel-Systemen finden beispielsweise elektromagnetische Blockiereinrichtungen Verwendung. Sie dienen dazu die Drehung des Zylinderkernes innerhalb des Schließzylinders zu blockieren. Hierzu ist der Elektromagnet im Zylindergehäuse angeordnet und dessen Anker (Sperrbolzen) wird durch den Magneten in eine Ausnehmung in den Zylinder bewegt, so daß der Zylinderkern nicht mehr gedreht werden kann.
Die Aktivierung des Magneten erfolgt bei diesen Systemen durch elektronisch codierte Schlüssel, deren Codierung von einem im Schließzylinder angeordneten Lesekopf gelesen wird. Bei passender Codierung erfolgt die Freigabe (DE 92 17 524.4 U1).For example, electromagnetic locking devices are used in electronic lock and key systems. They serve to block the rotation of the cylinder core within the lock cylinder. For this purpose, the electromagnet is arranged in the cylinder housing and its armature (locking pin) is moved into a recess in the cylinder by the magnet, so that the cylinder core can no longer be rotated.
In these systems, the magnet is activated by electronically coded keys, the coding of which is read by a reading head arranged in the locking cylinder. Appropriate coding is used for release (DE 92 17 524.4 U1).

Eine andere elektromotorische Blockierung ist aus der DE 197 06 822 A1.Another electromotive blocking is from DE 197 06 822 A1.

Bei anderen - aus der Praxis bekannten - verschließbaren Anlagen können z.B. den Schlüsselkanal abdeckende Scheiben blockiert werden, so daß kein Zugang zum Schlüsselkanal möglich ist.
Hierzu können ebenfalls Elektromagneten mit einen als Sperrbolzen ausgebildeten Anker eingesetzt werden.In other lockable systems known from practice, disks covering the key channel can be blocked, for example, so that no access to the key channel is possible.
Electromagnets with an armature designed as a locking bolt can also be used for this purpose.

Schließlich sind auch Verriegelungs- bzw. Verschlußeinrichtungen bekannt, die Elektromotoren als Antriebsmittel verwenden, wobei zur Verstellung der für die Schließung oder Sperrung zuständigen Bauteile eine Gewindekopplung zwischen Motor und Verstelleinrichtung vorgesehen ist (DE 197 27 422 C1, DE 37 16 507 A1, DE 90 01 993 U1 und DE 37 16 021 A1). Finally, locking and closing devices are also known Use electric motors as drive means, being used to adjust the closure or blocking responsible components a threaded coupling between the motor and Adjustment device is provided (DE 197 27 422 C1, DE 37 16 507 A1, DE 90 01 993 U1 and DE 37 16 021 A1).

Die ständige Verkleinerung elektrisch/elektronischer Einrichtungen und die dabei weiter bestehende Notwendigkeit zur Aufnahme relativ großer Kräfte erfordert aber auch andere Lösungen.The constant downsizing of electrical / electronic equipment and further the existing need to absorb relatively large forces also requires others Solutions.

Aufgabe der Erfindung ist es, eine Blockiereinrichtung zu schaffen, die in der Lage ist relativ große Kräfte aufzunehmen, wobei es sich hier im wesentlichen um auf den Sperrbolzen wirkende Querkräfte handelt, und die dennoch nur wenig Bauraum benötigt.

  • daß auf dem vom Motor abgewandten Ende der Abtriebswelle des Motors eine ein Außengewinde aufweisende Gewindehülse fest angeordnet ist,
  • daß die Gewindehülse mit einer sie umgebenden, ein Innengewinde aufweisenden, Mutter zusammenwirkt, die linear beweglich in dem die Mutter und den Motor umgebenden Gehäuse geführt ist,
  • daß die Mutter direkt mit dem durch eine Öffnung in dem Gehäuse nach außen schiebbaren Sperrbolzen verbunden ist und
  • daß einerseits zwischen dem Gehäuse und der Mutter, den Sperrbolzen innerhalb des Gehäuses umgebend, eine Druckfeder und andererseits zwischen der Mutter und dem Motor, die Abtriebswelle umgebend, eine weitere Druckfeder angeordnet ist.
The object of the invention is to provide a blocking device which is capable of absorbing relatively large forces, which are essentially transverse forces acting on the locking bolt, and which nevertheless requires only little installation space.
  • that a threaded sleeve with an external thread is fixedly arranged on the end of the output shaft of the motor facing away from the motor,
  • that the threaded sleeve interacts with a nut surrounding it, which has an internal thread and is guided in a linearly movable manner in the housing surrounding the nut and the motor,
  • that the nut is connected directly to the locking bolt which can be pushed outwards through an opening in the housing and
  • that on the one hand between the housing and the nut surrounding the locking bolt within the housing, a compression spring and on the other hand between the nut and the motor, surrounding the output shaft, a further compression spring is arranged.

Eine Ausgestaltung der Erfindung ergibt sich aus dem Anspruch 2.An embodiment of the invention results from claim 2.

Die Erfindung soll nachfolgend an den Zeichnungen erläutert werden. Dabei zeigt:

  • Fig.1 einen Schnitt durch eine elektromotorische Blockiereinrichtung im entriegelten also nicht blockierenden Zustand und
  • Fig.2 den verriegelten Zustand.
    • The invention will be explained below on the drawings. It shows:
  • 1 shows a section through an electromotive blocking device in the unlocked, ie non-blocking state, and
  • Fig.2 the locked state.

    • In einem Gehäuse 1 ist ein Elektromotor 2 angeordnet. Einzuleiten des Motor oder der Anschlüsse sind hier nicht dargestellt. Der Motor weist eine Abtriebswelle auf. Auf dem vom Motor abgekehrten Ende der Abtriebswelle ist eine Gewindehülse 5 fest angeordnet. Diese Gewindehülse weist ein Außengewinde auf. Dieses Außengewinde kämmt mit dem Innengewinde einer Mutter 4, die in dem Gehäuse linear verschiebbar geführt ist. Dreht sich die Abtriebswelle des Motors, so führt die Drehung der Gewindehülse 5 zu einer linearen Verschiebung der Mutter und damit des mit dieser verbundenen Sperrbolzens 4a. Je nach Drehrichtung wird der Sperrbolzen in das Gehäuse (durch eine Öffnung) zurückgezogen (entriegelte Stellung) oder linear vorgeschoben, so daß er dann die verriegelte Stellung einnimmt. Das Gegenstück zu Sperrbolzen, also das Teil, in das der Sperrbolzen eingreift ist hier - aus Gründen der Übersicht - nicht dargestellt.An electric motor 2 is arranged in a housing 1. Initiate the engine or the Connections are not shown here. The engine has an output shaft. On the from End of the output shaft remote from the motor, a threaded sleeve 5 is fixed. This Threaded sleeve has an external thread. This external thread meshes with the Internal thread of a nut 4, which is guided in a linearly displaceable manner in the housing. Turns the output shaft of the motor, the rotation of the threaded sleeve 5 leads to a linear Displacement of the nut and thus the locking bolt 4a connected to it. Depending on The locking pin is pulled back into the housing (through an opening) (unlocked position) or advanced linearly so that he then the locked position occupies. The counterpart to locking bolts, i.e. the part in which the locking bolt engages is not shown here for reasons of clarity.

    An der Mutter 4 ist ein Permanentmagnet befestigt, der durch einen Schlitz aus dem Gehäuse herausragt.On the nut 4, a permanent magnet is attached through a slot from the Housing protrudes.

    Dieser Permanentmagnet 6 wirkt mit einem nicht dargestellten Reedkontakt zusammen, so daß berührungsfrei die Position der Mutter und damit des Sperrbolzens nach außen übertragbar ist:This permanent magnet 6 interacts with a reed contact, not shown, so that contact-free the position of the nut and thus the locking bolt to the outside is transferable:
