Abstract

Die vorliegende Erfindung betrifft eine Feststellvorrichtung für eine vorzugsweise mit einem Türschließer versehene Tür, Insbesondere eine für Brandachutzzwecke ausgebildete Tür bzw. Türkonstruktion, mit einem Elektromagneten (1) und einem mit dem Elektromagneten (1) zusammenwirkenden Anker (2), wobei der Elektromagnet (1) und der mit dem Elektromagneten (1) zusammenwirkende Anker (2) in der Lage sind, die geöffnete Tür - vorzugsweise gegen die Schließkraft des Türschließers - in einer Offenstellung zu halten. Um eine sichere Offenhaltung der Tür zu ermöglichen und insbesondere das Absenken des Türblattes bzw. Türflügels zu vermeiden weist die mit dem Anker (2) zusammenwirkende Oberfläche des Elektromagneten (1) wenigstens einen Vorsprung (3) und/oder wenigstens eine Vertiefung (9, 11) auf und weist die mit dem Elektromagneten (1) zusammenwirkende Oberfläche des Ankers (2) wenigstens eine Vertiefung (4) und/oder wenigstens einen Vorsprung (10, 12) auf, wobei der Vorsprung (3) und/oder die Vertiefung (9, 11) der Oberfläche des Elektromagneten (1) sowie die Vertiefung (4) und/oder der Vorsprung (10, 12) der Oberfläche des Ankers (2) derart aufeinander abgestimmt ausgebildet sind, dass der Vorsprung (3) der Oberfläche des Elektromagneten (1) bzw. der Vorsprung (10, 12) der Oberfläche des Ankers (2) im Wesentlichen formschlüssig in bzw. von der Vertiefung (9, 11) der Oberfläche des Elektromagneten (1) bzw. In bzw. von der Vertiefung (4) der Oberfläche des Ankers (2) aufnehmbar ist.

The present invention relates to a locking device for a preferably provided with a door closer door, in particular designed for fire safety purposes door or door construction, with an electromagnet (1) and with the electromagnet (1) cooperating armature (2), wherein the electromagnet (1 ) and cooperating with the electromagnet (1) anchor (2) are able to keep the open door - preferably against the closing force of the door closer - in an open position. In order to allow a secure opening of the door and in particular to avoid the lowering of the door leaf or door leaf, the surface of the electromagnet (1) cooperating with the armature (2) has at least one projection (3) and / or at least one recess (9, 11 ) and the cooperating with the electromagnet (1) surface of the armature (2) at least one recess (4) and / or at least one projection (10, 12), wherein the projection (3) and / or the recess (9 , 11) of the surface of the electromagnet (1) and the depression (4) and / or the projection (10, 12) of the surface of the armature (2) are designed to be matched to one another such that the projection (3) of the surface of the electromagnet ( 1) or the projection (10, 12) of the surface of the armature (2) substantially in a form-fitting manner in or from the recess (9, 11) of the surface of the electromagnet (1) or in or of the recess (4) the surface of the armature (2) is receivable.
