Abstract

Lift shaft door has at least two door leafs (2, 3). Holding plates (4, 5) with square shoulders (4.1, 5.1) provided on the rear side of the door leafs contain exchangeable profiles (6, 7) determining the further course in the rear region of the lift shaft door of a gap (8) produced in the front region of the lift shaft door between the door leafs. Preferred Features: The profiles have walls (6.1, 7.1) angled toward the rear side of the lift shaft door and crossing an axis of symmetry (9) of the lift shaft door. The walls determine the further course of the gap and form a fire obstacle.

Description

Die Erfindung betrifft eine Aufzug-Schachttüre, wobei die Aufzug-Schachttüre mindestens zwei Türflügel aufweist.The invention relates to an elevator landing door, the Elevator landing door has at least two door leaves.

Die Schachttüren von Aufzügen sind oft mit Brandschikanen ausgestattet. Hierbei sind beispielsweise an den Schliesskanten der Türflügel rechteckige Absätze vorgesehen, die im geschlossenen Zustand der Aufzug-Schachttüre ineinandergreifen, so dass der Türspalt im Querschnitt einen stufenförmigen Verlauf aufweist. Auf diese Weise soll verhindert werden, dass ein auf einem Stockwerk entstandener Brand über den Aufzugsschacht auf andere Stockwerke übergreifen kann. Bei derartigen Aufzug-Schachttüren verläuft der Türspalt bei gleichen Türflügeln vom Stockwerk aus gesehen zwangsläufig unsymmetrisch, was visuell als störend und unschön empfunden werden kann.The shaft doors of elevators are often fire bombarded fitted. Here are, for example, on the closing edges the door wing provided rectangular paragraphs, which in interlock the closed state of the elevator landing door, so that the door gap has a step-shaped cross section Has history. This is supposed to prevent be that a fire started on one floor can spread the elevator shaft to other floors. With such elevator landing doors, the door gap runs along same door leaves seen from the floor inevitably asymmetrical, which is visually bothersome and unsightly can be.

Mit der Europäischen Patentschrift 0 479 239 ist eine Aufzugsschachttür bekannt geworden, bei der eine schachtseitig angeordnete, mit wärmeisolierendem Material gefüllte Grundeinheit und ein stockwerkseitig angeordnetes Isolationspanel mit wärmeisolierendem Futter schichtartig aneinanderliegen. Die Grundeinheiten der beiden Türflügel sind wie eingangs beschrieben an ihren Kanten stufenförmig ausgebildet und greifen im geschlossenen Zustand ineinander, wobei sie eine Brandschikane bilden. Die Kanten der stockwerkseitig angeordneten Isolationspanele der beiden Türflügel bilden einen derart plazierten Türspalt, dass die Brandschikane von dem einen Türflügel überdeckt wird.European Patent 0 479 239 is one Elevator shaft door became known in which one shaft side arranged, filled with heat insulating material Basic unit and an insulation panel arranged on the floor lay together in layers with heat-insulating lining. The basic units of the two door leaves are like described at the beginning of step-shaped at their edges and interlock when closed, whereby they form a fire chicane. The edges of the floor side arranged insulation panels of the two door leaves form a door gap so placed that the fire chicane from which a door wing is covered.

Der Erfindung liegt die Aufgabe zugrunde eine Schachttür für Aufzüge gemäss Oberbegriff vorzuschlagen, bei der anstelle einer einmal festgelegten, bestimmten Brandschikane - wie aus vorstehend genannten Stand der Technik ersichtlich - variable Brandschikanen bzw. Türkantengestaltungen möglich sind, und die die einschlägigen Vorschriften für die Sicherheit bei Bränden erfüllen kann.The invention has for its object a shaft door for Propose lifts according to the generic term, instead of a once determined, certain fire chicane - how can be seen from the aforementioned prior art - variable fire baffles or door edge designs possible and which are the relevant regulations for the Fire safety can meet.

Diese Aufgabe wird durch die im Patentanspruch 1 angegebene Erfindung gelöst. Hierbei sind an den Rückseiten der Türflügel Haltebleche mit rechtwinkligen Absätzen vorgesehen, in welche auswechselbare Profile eingesetzt sind. Durch die Profile wird der weitere Verlauf eines im vorderen Bereich der Aufzug-Schachttüre gegebenen Türspaltes in deren hinteren Bereich bestimmt.This object is achieved by the specified in claim 1 Invention solved. Here are on the back of the Door leaf retaining plates provided with right-angled heels, in which interchangeable profiles are used. By the profiles will be the further course of one in the front Area of the elevator shaft door given the door gap in their rear area determined.

In einer besonderen Ausführungsform weisen die Profile schräg zur Rückseite der Aufzug-Schachttüre verlaufende, eine Symmetrieachse der Aufzug-Schachttüre kreuzende Wände auf, durch die der weitere verlauf des Türspaltes bestimmt und eine Brandschikane gebildet wird.In a special embodiment, the profiles diagonally to the back of the elevator landing door walls crossing an axis of symmetry of the elevator landing door which determines the further course of the door gap and a fire chicane is formed.

Die mit der Erfindung erzielten Vorteile liegen insbesondere darin, dass für ein und denselben Schachttürtyp durch Auswechseln der Profile verschiedene Brandschikanen realisiert werden können. Wie durch Feuertests erwiesen, bleibt mit der vorgeschlagenen Konstruktion der messbare Türspalt unter der vorgeschriebenen maximalen Breite von 6 mm. Weitere Vorteile liegen darin, dass unabhängig von der Form der Brandschikane der vom Stockwerk aus sichtbare Türspalt zwischen den Türflügeln genau in der Symmetrieachse der Aufzug-Schachttüre verläuft, und dass die, die Brandschikane bildenden Profile, falls erforderlich, als Trägerprofile für Dichtungen dienen können. The advantages achieved with the invention are in particular in that for one and the same type of landing door Exchanging the profiles realized different fire baffles can be. As proven by fire tests, remains with the proposed construction of the measurable door gap below the prescribed maximum width of 6 mm. Other advantages are that regardless of the shape the fire chicane the door gap visible from the floor between the door leaves exactly in the symmetry axis of the Elevator shaft door runs, and that, the fire chicane forming profiles, if necessary, as support profiles for Seals can serve.
