Description

Die Erfindung betrifft einen Türrahmen mit einer Kammer zur Aufnahme einer Steuereinheit einer Aufzugsanlage.The invention relates to a door frame with a chamber for accommodating a control unit of an elevator installation.

Aufzugsanlagen umfassen eine Aufzugskabine, die üblicherweise vertikal entlang eines Aufzugsschachtes verfahrbar ist. Die Aufzugskabine kann demnach so verfahren werden, dass sie an einzelnen Schachttüren anordenbar ist, so dass ein Zugang von der Aufzugskabine zu dem der einzelnen Schachttür zugehörigen Stockwerk realisiert ist. Die Aufzugsanlage umfasst darüber hinaus eine Steuereinheit, die im Wesentlichen zur Steuerung der Aufzugsanlage, insbesondere zur Verfahrbarkeit der Aufzugskabine erforderlich ist. Darüber hinaus kann eine solche Steuereinheit für einen Service der Aufzugsanlage und die Diagnostik notwendige Schnittstellen und Eingabemodule enthalten. Zweckmässig ist diese Steuereinheit so anzuordnen, dass ein Service der Aufzugsanlage bzw. der Steuereinheit einfach durchführbar ist. Folglich ist es von Vorteil, die Steuereinheit in einem Türrahmen einer solchen Schachttür anzuordnen. Ein solcher Türrahmen ist üblicherweise durch einen Türsturz und eines jeweils seitlich der Türöffnung ausgebildeten Türpfostens gebildet. Zur Aufnahme der Steuereinheit kann einer dieser zwei Türpfosten in seinem Inneren eine Kammer ausbilden, welche durch Seitenwände des Türpfostens begrenzt sind.Elevator installations include an elevator car, which can usually be moved vertically along an elevator shaft. Accordingly, the elevator car can be moved in such a way that it can be arranged on individual shaft doors, so that access from the elevator car to the floor associated with the individual shaft door is realized. The elevator installation also includes a control unit, which is essentially required for controlling the elevator installation, in particular for the mobility of the elevator car. In addition, such a control unit can contain the interfaces and input modules required for servicing the elevator installation and for diagnostics. This control unit is expediently arranged in such a way that the elevator installation or the control unit can be serviced easily. Consequently, it is advantageous to arrange the control unit in a door frame of such a shaft door. Such a door frame is usually formed by a door lintel and a door post formed on the side of the door opening. To accommodate the control unit, one of these two door jambs can form a chamber in its interior, which is delimited by side walls of the door jamb.

EP1518815 zeigt einen solchen mit einer Kammer ausgebildeten Türpfosten. Vom Stockwerk aus ist das Innere der Kammer und damit die Steuereinheit mittels einer zu öffnenden Klappe erreichbar. Eine weitere Öffnung des Türpfostens ist derart angeordnet, dass aus dem Inneren des Aufzugsschachtes eine Wartung an der Steuereinheit durchführbar ist. Zur Wartung der Steuereinheit ist es daher notwendig, dass der Servicetechniker vor dieser Öffnung ist. Dies ist dadurch erreichbar, dass das Dach der Aufzugskabine unmittelbar unterhalb dieser Öffnung platziert ist, so dass der Servicetechniker vom Dach der Aufzugskabine diese Wartung vornehmen kann. EP1518815 shows such a chambered door jamb. The interior of the chamber and thus the control unit can be reached from the floor by means of a flap that can be opened. A further opening of the door post is arranged in such a way that maintenance can be carried out on the control unit from inside the elevator shaft. To maintain the control unit, it is therefore necessary for the service technician to be in front of this opening. This can be achieved by placing the roof of the elevator car immediately below this opening, so that the service technician can carry out this maintenance from the roof of the elevator car.

EP0680921 offenbart einen Türrahmen gemäß dem Oberbegriff von Anspruch 1. EP0680921 discloses a door frame according to the preamble of claim 1.

Nachteilig ist demnach, dass die Aufzugskabine derart im Aufzugsschacht angeordnet sein muss, dass das Dach der Aufzugskabine als Arbeitsplattform zur Wartung der Steuereinheit dienen kann.Accordingly, it is disadvantageous that the elevator car must be arranged in the elevator shaft in such a way that the roof of the elevator car can serve as a working platform for maintaining the control unit.

Daher ist es Aufgabe der Erfindung, einen Türrahmen zu schaffen, welcher eine verbesserte Zugänglichkeit einer im Türrahmen anordenbaren Steuereinheit ermöglicht.It is therefore the object of the invention to create a door frame which enables improved accessibility of a control unit which can be arranged in the door frame.

Die Aufgabe wird gelöst durch einen Türrahmen einer einen Aufzugsschacht aufweisenden Aufzugsanlage, wobei der Türrahmen eine Kammer zur Aufnahme einer Steuereinheit ausbildet, der Türrahmen aufweisend ein erstes die Kammer begrenzendes Türrahmenelement mit einem geradlinig verlaufenden Seitenabschluss, ein zweites die Kammer begrenzendes Türrahmenelement mit einem Seitenabschluss parallel des Seitenabschlusses des ersten Türrahmenelementes, und wobei das erste Türrahmenelement mittels eines sich entlang der Seitenabschlüsse erstreckenden Befestigungselementes am zweiten Türrahmenelement fixierbar und das Befestigungselement entlang der Seitenabschlüsse verschiebbar am ersten und am zweiten Türrahmenelement angeordnet ist, und das Befestigungselement ein Werkzeugelement zum Verschieben des Befestigungselementes aus einer Verriegeltenstellung in eine Freigabestellung aufweist, wobei das erste Türrahmenelement in der Verriegeltenstellung am zweiten Türrahmenelement fixiert und in der Freigabestellung vom zweiten Türrahmenelement entnehmbar ist.The object is achieved by a door frame of an elevator system having an elevator shaft, the door frame forming a chamber for accommodating a control unit, the door frame having a first door frame element delimiting the chamber with a side end running in a straight line, a second door frame element delimiting the chamber with a side end parallel to the Side closure of the first door frame element, and wherein the first door frame element can be fixed to the second door frame element by means of a fastening element extending along the side closures and the fastening element is arranged on the first and second door frame element so that it can be displaced along the side closures, and the fastening element is a tool element for displacing the fastening element from a locked position into a release position, wherein the first door frame element is fixed to the second door frame element in the locked position and can be removed from the second door frame element in the release position.

Der Erfindung liegt die Erkenntnis zugrunde, dass eine Zugänglichkeit des Mechanismus zur Fixierung der die Kammer begrenzenden Türrahmenelemente ausschlaggebend ist, um eine schnelle und einfache Wartung der Steuereinheit zu ermöglichen. Demnach ist eine Anordnung der Aufzugskabine an dem mit dem vorzugweise schachttürseitigen Türrahmen versehenen Stockwerk, so dass ein Innenraum der Aufzugskabine von diesem Stockwerk aus begehbar ist, eine Möglichkeit, die Wartung wesentlich zu vereinfachen.The invention is based on the finding that accessibility of the mechanism for fixing the door frame elements delimiting the chamber is crucial in order to enable quick and easy maintenance of the control unit. Accordingly, arranging the elevator car on the floor preferably provided with the door frame on the shaft door side, so that an interior space of the elevator car can be accessed from this floor, is a possibility of significantly simplifying maintenance.

Vorraussetzung dafür ist einerseits, dass das für die Wartung zu entfernende erste Türrahmenelement entfernt werden kann, wenn der Innenraum der Aufzugskabine begehbar am Stockwerk angeordnet ist. Andererseits ist es notwendig, dass dieses zu entfernende erste Türrahmenelement bzw. die durch die Entfernung des ersten Türrahmenelementes entstehende Öffnung des Türrahmens genügend gross für die Wartung der Steuereinheit ausgebildet ist.A prerequisite for this is, on the one hand, that the first door frame element to be removed for maintenance can be removed when the interior of the elevator car is arranged on the floor so that it can be walked on. On the other hand, it is necessary for this first door frame element to be removed or the opening in the door frame resulting from the removal of the first door frame element to be sufficiently large for maintenance of the control unit.

Demnach sind zwei Türrahmenelemente durch ein Befestigungselement miteinander verbindbar. Das bedeutet, dass das erste Türrahmenelement am zweiten Türrahmenelement durch das Befestigungselement in seiner Verriegeltenstellung fixiert ist. Das Befestigungselement kann mittels des Werkzeuges entlang beider Seitenabschlüsse verschoben werden, so dass die Verriegelung freigebbar ist. Zweckmässigerweise kann das Befestigungselement so angeordnet sein, dass das Werkzeug in einen Zwischenraum in die Flucht zwischen dem schachttürseitigen Türrahmen und der Aufzugskabine, insbesondere einem Türrahmen der Aufzugskabine einzuschieben ist, um das Befestigungselement zum Lösen des Türrahmenelementes zu entriegeln. Durch diese freigegebene Verriegelung, d.h. die Freigabestellung des Befestiungselementes, können beide Türrahmenelemente zueinander bewegt werden. Das heißt, dass das erste Türrahmenelement so entfernt werden kann, dass die Kammer innerhalb des Türrahmens zugänglich ist.Accordingly, two door frame elements can be connected to one another by a fastening element. This means that the first door frame element on the second door frame element is fixed by the fastener in its locked position. The fastener can be moved along both side ends by means of the tool so that the lock can be released. The fastening element can expediently be arranged in such a way that the tool can be inserted into an intermediate space in the alignment between the shaft door-side door frame and the elevator car, in particular a door frame of the elevator car, in order to unlock the fastening element to release the door frame element. Due to this released locking, ie the release position of the fastening element, both door frame elements can be moved towards one another. That is, the first door frame member can be removed so that the chamber within the door frame is accessible.

Bei einer Weiterbildung des Türrahmens weist das erste Türrahmenelement einen zweiten geradlinig verlaufenden Seitenabschluss auf, und wobei der Türrahmen ein zweites Befestigungselement zur Fixierung des ersten Türrahmenelementes am zweiten oder einem weiteren Türrahmenelement aufweist, und wobei das zweite Türrahmenelement einen zweiten Seitenabschluss bzw. das weitere Türrahmenelement einen Seitenabschluss aufweist und das zweite Befestigungselement ein Werkzeugelement zum Verschieben des zweiten Befestigungselementes aus einer Verriegeltenstellung in eine Freigabestellung aufweist, wobei das erste Türrahmenelement in der Verriegeltenstellung am zweiten bzw. weiteren Türrahmenelement fixiert und in der Freigabestellung vom zweiten bzw. weiteren Türrahmenelement entnehmbar ist.In a further development of the door frame, the first door frame element has a second rectilinear side closure, and the door frame has a second fastening element for fixing the first door frame element to the second or a further door frame element, and the second door frame element has a second side closure or the further door frame element has one side closure and the second fastening element has a tool element for moving the second fastening element from a locked position into a release position, the first door frame element being fixed to the second or further door frame element in the locked position and being removable from the second or further door frame element in the released position.

Das heisst, dass das entfernbare erste Türrahmenelement mittels des zweiten Befestigungselementes an dem zweiten Seitenabschluss des ersten Türrahmenelementes am zweiten Türrahmenelement oder dem weiteren Türrahmenelement des die Kammer ausbildenden Türpfostens fixierbar sein kann. Die technischen Merkmale des ersten bzw. des zweiten/weiteren Türrahmenelementes wäre demnach analog der vorab beschriebenen technischen Merkmale zur Befestigung des ersten am zweiten Türrahmenelement. Derart ist ermöglicht, dass das erste Türrahmenelement entnehmbar ist, wenn das erste und das zweite Befestigungselement in ihrer Freigabestellung angeordnet sind.This means that the removable first door frame element can be fixed by means of the second fastening element on the second side end of the first door frame element on the second door frame element or the further door frame element of the door jamb forming the chamber. The technical features of the first or the second/additional door frame element would therefore be analogous to the technical features described above for fastening the first to the second door frame element. This makes it possible for the first door frame element to be removable when the first and second fastening elements are arranged in their release position.

Bei einer Weiterbildung des Türrahmens weisen das erste Türrahmenelement einen zweiten geradlinig verlaufenden Seitenabschluss, und der Türrahmen ein entlang dieses zweiten dem ersten Türrahmenelement zugeordneten Seitenabschlusses verlaufendes Scharnier zur Fixierung des ersten Türrahmenelementes am zweiten oder einem weiteren Türrahmenelement auf und das Scharnier derart ausgebildet ist, dass das erste Türrahmenelement am Scharnier schwenkbar ist. Folglich ist ermöglicht, dass das erste Türrahmenelement die im Türrahmen angeordnete Kammer freigeben kann, wenn das (erste) Befestigungselement in seiner Freigabestellung angeordnet ist, indem das erste Türrahmenelement um die Achse des Scharnieres in eine Öffnungsposition geschwenkt werden kann.In a further development of the door frame, the first door frame element has a second side end running in a straight line, and the door frame has a side end running along this second side end associated with the first door frame element Hinge for fixing the first door frame element on the second or a further door frame element and the hinge is designed such that the first door frame element is pivotable on the hinge. Consequently, it is possible for the first door frame element to be able to release the chamber arranged in the door frame when the (first) fastening element is arranged in its release position, in that the first door frame element can be pivoted about the axis of the hinge into an open position.

Bei einer Weiterbildung des Türrahmens ist das Werkzeugelement durch eine Erhebung oder eine Vertiefung oder einen Durchbruch, insbesondere durch einen Stift oder durch ein Loch, gebildet. Mittels eines als Erhebung, beispielhaft als Stift, ausgebildeten Werkzeugelementes, welches Werkzeugelement über die Ebene des Türrahmenelementes aus dem Türpfosten nach aussen ragt, ist ermöglicht, dass ein parallel des die Kammer begrenzenden Türrahmenelementes geführtes Werkzeug zum Überführen des Befestigungselementes aus seiner Verriegeltenstellung in seine Freigabestellung genutzt werden kann und vice versa. Derart können Befestigungselemente betätigt werden, die zwischen Schacht- und Kabinentürpfosten angeordnet sind. Mittels einer Vertiefung oder eines Durchbruches, insbesondere eines Loches, kann das Werkzeug zwischen die nebeneinander angeordneten Seitenabschlüsse des ersten und des zweiten Türrahmenelementes geführt und in die Vertiefung bzw. das Loch gesteckt werden um das Befestigungselement aus seiner Verriegeltenstellung in seine Freigabestellung zu überführen oder vice versa.In a further development of the door frame, the tool element is formed by an elevation or a depression or an opening, in particular by a pin or a hole. By means of a tool element designed as an elevation, for example as a pin, which tool element protrudes outwards from the door post above the level of the door frame element, it is possible for a tool guided parallel to the door frame element delimiting the chamber to be used to transfer the fastening element from its locked position to its release position can be and vice versa. In this way fastening elements can be actuated which are arranged between shaft and car door jambs. By means of a recess or an opening, in particular a hole, the tool can be guided between the side closures of the first and second door frame element arranged next to one another and inserted into the recess or the hole in order to move the fastening element from its locked position to its release position or vice versa .

Bei einer Weiterbildung des Türrahmens weist das erste Türrahmenelement mindestens ein sich entlang des (ersten) Seitenabschlusses erstreckendes Andockelement und das Befestigungselement jeweils einen dem mindestens einen Andockelement zuordenbaren Finger auf, wobei das/die Andockelement(e) und/oder der/die Finger derart abgewinkelt bzw. ausgebildet sind, dass das mindestens eine Andockelement den dem Andockelement zuordenbaren Finger in seiner Verriegeltenstellung des Befestigungselementes zur Vermeidung des Lösens des ersten Türrahmenelementes vom Befestigungselement formschlüssig hintergreift und durch Verschieben des Befestigungselementes in seine Entriegeltenstellung die Formschlüssigkeit aufhebbar ist, und somit das erste Türrahmenelement vom Befestigungselement lösbar ist. Vorteilhaft ist, dass in einer ersten Stellung, der Verriegelungsstellung, ein erster Finger das Andockelement derart hintergreift, dass das erste Türrahmenelement formstabil mit dem Befestigungselement verbunden ist.In a further development of the door frame, the first door frame element has at least one docking element extending along the (first) side end, and the fastening element each has a finger that can be assigned to the at least one docking element, with the docking element(s) and/or the finger(s) being angled in this way or are designed such that the at least one docking element engages behind the finger that can be assigned to the docking element in its locked position of the fastening element in a form-fitting manner in order to prevent the first door frame element from being released from the fastening element and that the form-fitting connection can be canceled by moving the fastening element into its unlocked position, and thus the first door frame element from Fastener is detachable. It is advantageous that in a first position, the locking position, a first finger engages behind the docking element in such a way that the first door frame element is connected to the fastening element in a dimensionally stable manner.

Durch Verschieben des Befestigungselementes vorzugsweise entlang der Hauptausrichtung des Türrahmenelementes kann das Befestigungselement in seiner entriegelten Stellung verschoben werden, so dass das erste Türrahmenelement vom Befestigungselement lösbar ist. Entsprechend kann das erste Türrahmenelement von der Kammer vorzugsweise manuell entnommen bzw. entfernt werden.By displacing the fastening element, preferably along the main orientation of the door frame element, the fastening element can be shifted into its unlocked position, so that the first door frame element can be detached from the fastening element. Correspondingly, the first door frame element can preferably be removed or removed from the chamber manually.

Bei einer Weiterbildung des Türrahmens weist bzw. weisen das zweite Türrahmenelement entlang seines Seitenabschlusses und/oder das Befestigungselement eine Abkantung bzw. Abkantungen zur formschlüssigen Verbindung des zweiten Türrahmenelementes mit dem Befestigungselement auf. Vorteilhaft ist, dass demnach das Befestigungselement verschiebbar am zweiten Türrahmenelement angeordnet ist, aber dennoch vorzugsweise nicht entfernbar ist. Entsprechend kann das Befestigungselement aus seiner verriegelten Stellung in seine entriegelte Stellung oder vice versa verschoben werden, ohne verlustig zu gehen.In a further development of the door frame, the second door frame element has or have a bevel or bevels along its side end and/or the fastening element for the form-fitting connection of the second door frame element to the fastening element. It is advantageous that the fastening element is arranged in a displaceable manner on the second door frame element, but is nevertheless preferably non-removable. Accordingly, the fastener can be shifted from its locked position to its unlocked position or vice versa without being lost.

Bei einer Weiterbildung des Türrahmens sind die durch das Befestigungselement verbindbaren Seitenabschlüsse des ersten bzw. des zweiten Türrahmenelementes dem Aufzugsschacht zugewandt und der Stift ragt in den Aufzugsschacht. Derart ist ermöglicht, dass das Befestigungselement weitgehend vor dem Aufzugspassagier verborgen also dem Stockwerk bzw. dem Innenraum der Kabine abgewandt angeordnet ist und der Stift des Befestigungselementes lediglich mittels des Werkzeugs bedienbar ist. Demnach ist eine Öffenbarkeit dieser im Türrahmen angeordneten Kammer nicht offensichtlich und somit kann eine solche unbeabsichtige Öffnung des Türrahmens verhindert werden. Trotz dieses Vorteils ist aber ermöglicht, dass die Kammer des Türrahmens durch Verschieben des Befestigungselementes öffenbar ist.In a further development of the door frame, the side closures of the first and second door frame element, which can be connected by the fastening element, face the elevator shaft and the pin protrudes into the elevator shaft. In this way it is possible for the fastening element to be largely hidden from the elevator passenger, that is to say it is arranged facing away from the floor or the interior of the car and the pin of the fastening element can only be operated using the tool. Accordingly, an openability of this chamber arranged in the door frame is not obvious and thus such an unintentional opening of the door frame can be prevented. Despite this advantage, however, it is possible for the chamber of the door frame to be opened by moving the fastening element.

Bei einer Weiterbildung weist der Türrahmen einen Türpfosten auf, welcher Türpfosten zur Anordnung seitlich der durch den Türrahmen umschlossenen Türöffnung vorgesehen ist und der Türpfosten die Türrahmenelemente umfasst. Folglich ist ermöglicht, dass die in der Kammer platzierbare Steuereinheit so in ihrer vertikalen Höhe anordenbar ist, dass die Wartung für den Servicetechniker auf einfache Weise erfolgen kann, das heisst beispielsweise ohne notwendigerweise die Wartung von einer Leiter aus durchführen zu müssen.In a further development, the door frame has a door post, which door post is provided for arrangement to the side of the door opening enclosed by the door frame and the door post encompasses the door frame elements. Consequently, it is possible for the control unit that can be placed in the chamber to be arranged in its vertical height in such a way that maintenance can be carried out easily for the service technician, ie for example without necessarily having to carry out maintenance from a ladder.

Bei einer Weiterbildung des Türrahmens sind die dem ersten Türrahmenelement zugordnete Seitenabschluss und die dem zweiten Türrahmenelement zugeordnete Seitenabschluss vertikal ausgerichtet. Durch eine entsprechend vertikale Ausrichtung des Befestigungselementes ist der Türrahmen entlang einer hohen vertikal ausgerichteten Länge öffenbar. Entsprechend kann die Öffnung des Türrahmens zur Wartung der Steuereinheit gross ausgebildet sein, was die Wartung der Steuereinheit vereinfacht.In a development of the door frame, the side closure assigned to the first door frame element and the side closure assigned to the second door frame element are aligned vertically. The door frame can be opened along a long vertically aligned length by a corresponding vertical alignment of the fastening element. Accordingly, the opening of the door frame for maintenance of the control unit can be made large, which simplifies the maintenance of the control unit.

Bei einer Weiterbildung des Türrahmens ist das erste Türrahmenelement durch ein Eckelement des Türrahmens gebildet. Das bedeutet, dass das erste Türrahmenelement vorzugsweise eine parallel seines Seitenabschlusses ausgerichtete Abwinklung, vorzugsweise gebildet durch einen Winkel von 70° bis 110°, vorzugsweise 90°, zur Ausbildung des Eckelementes aufweist. Eine solche Abwinklung bewirkt eine erhöhte Stabilität des derart gebildeten Türrahmenelementes, so dass das erste Türrahmenelement keine zusätzlichen Verstärkungen bzw. Verstärkungselemente aufweisen muss.In a development of the door frame, the first door frame element is formed by a corner element of the door frame. This means that the first door frame element preferably has a bend aligned parallel to its side closure, preferably formed by an angle of 70° to 110°, preferably 90°, for forming the corner element. Such an angling brings about increased stability of the door frame element formed in this way, so that the first door frame element does not have to have any additional reinforcements or reinforcing elements.

Der Aufzugsschacht 4 weist mehrere üblicherweise vertikal übereinander angeordnete Schachttüröffnungen auf, wobei die Schachttüröffnungen einen Zugang des Innenraumes des Aufzugsschachtes zu Stockwerkböden 30a, 30b, 30c, 30d ermöglichen. Die Schachttüröffnungen sind in einer Gebäudewand 24 ausgebildet.The elevator shaft 4 has a plurality of shaft door openings which are usually arranged vertically one above the other, the shaft door openings providing access to the interior of the elevator shaft to floors 30a, 30b, 30c, 30d. The landing door openings are formed in a building wall 24 .

An jeder dieser Schachttüröffnungen ist eine dem Stockwerkboden 30a, 30b, 30c, 30d zuordenbare Schachttür 18a, 18b, 18c, 18d angeordnet. Die Aufzugskabine 6 weist eine Kabinentür 16 auf. Diese Kabinentür 16 bzw. die Aufzugskabine 6 ist durch Verfahren der Aufzugskabine 6 im Aufzugsschacht 4 an einer der Schachttüren 18a, 18b, 18c, 18d anordenbar.A shaft door 18a, 18b, 18c, 18d that can be assigned to the floor 30a, 30b, 30c, 30d is arranged at each of these shaft door openings. The elevator car 6 has a car door 16 . This car door 16 or the elevator car 6 can be arranged on one of the shaft doors 18a, 18b, 18c, 18d by moving the elevator car 6 in the elevator shaft 4.

Figur 2 zeigt eine an einem dieser Stockwerksböden 30 angeordnete Schachttür 18. Die Schachttür 18 umfasst im Wesentlichen einen Türrahmen 22 und mindestens ein Türblatt 20.1, 20.2, wobei die Türöffnung mittels des mindestens einen Türblattes 20.1, 20.2 verschliess- bzw. öffenbar ist. Die Türöffnung ist in einer Gebäudewand 24 ausgebildet, wobei diese Gebäudewand 24 üblicherweise den Aufzugsschacht 4 einseitig begrenzt. Der Türrahmen 22 umfasst zwei Türpfosten 22.1, 22.2 und einen Türsturz 22.3. Ein erster der beiden Türpfosten 22.1 ist einseitig der Türöffnung angeordnet, der zweite der Türpfosten 22.2 ist andernseitig der Türöffnung angeordnet. Der Türsturz 22.3 ist oberhalb der Türöffnung angeordnet. figure 2 shows a shaft door 18 arranged on one of these floors 30. The shaft door 18 essentially comprises a door frame 22 and at least one door leaf 20.1, 20.2, the door opening being able to be closed or opened by means of the at least one door leaf 20.1, 20.2. The door opening is formed in a building wall 24, this building wall 24 usually delimiting the elevator shaft 4 on one side. The door frame 22 includes two door jambs 22.1, 22.2 and a lintel 22.3. A first of the two door posts 22.1 is arranged on one side of the door opening, the second of the door posts 22.2 is arranged on the other side of the door opening. The lintel 22.3 is arranged above the door opening.

Einer der beiden Türpfosten 22.1, 22.2 oder der Türsturz 22.3 weist eine Kammer auf. Beispielhaft in Figur 2 ist gezeigt, dass die Kammer innerhalb einem der Türpfosten 22.1 angeordnet ist. Der Türpfosten 22.1 weist die Kammer begrenzende Wände 26.1, 26.3 auf.One of the two door jambs 22.1, 22.2 or the lintel 22.3 has a chamber. Exemplary in figure 2 the chamber is shown to be located within one of the jambs 22.1. The door post 22.1 has walls 26.1, 26.3 delimiting the chamber.

Figur 3 zeigt den in Figur 2 dargestellten die Kammer 26 aufweisenden Türpfosten 22.1 im Querschnitt, wobei die Aufzugskabine 6 an der Schachttür 18, zu welcher der Türpfosten 22.1 zugeordnet ist, angeordnet ist. Innerhalb der Kammer 26 ist eine Steuerungseinheit 60 angeordnet. Der Türpfosten 22.1 weist ein erstes und ein zweites die Kammer 26 begrenzendes Türrahmenelement 28.0, 28.1 auf, wobei das gemäss Figur 3 dargestellte zweite Türrahmenelement 28.1 durch mehrere Türrahmenelemente gebildet sein kann. Das erste Türrahmenelement 28.0 und das zweite Türrahmenelement 28.1 sind unmittelbar aneinander mittels eines ersten Befestigungselementes 32 fixierbar. Das erste Türrahmenelement 28.0 ist derart entfernbar, dass die Kammer 26 bzw. die in der Kammer 26 anordenbare bzw. angeordnete Steuereinheit 60 für einen Servicetechniker vom Stockwerk zugänglich ist. figure 3 shows the in figure 2 door post 22.1, which has the chamber 26, is shown in cross section, with the elevator car 6 being arranged on the shaft door 18, to which the door post 22.1 is assigned. A control unit 60 is arranged within the chamber 26 . The door post 22.1 has a first and a second door frame element 28.0, 28.1 delimiting the chamber 26, with the according to FIG figure 3 illustrated second door frame element 28.1 can be formed by several door frame elements. The first door frame element 28.0 and the second door frame element 28.1 can be fixed directly to one another by means of a first fastening element 32. The first door frame element 28.0 can be removed in such a way that the chamber 26 or the control unit 60 that can be arranged or arranged in the chamber 26 can be removed by a service technician floor is accessible.

Vorzugsweise ist das entfernbare erste Türrahmenelement 28.0 als Eckelement ausgebildet. Die in Figur 3 dargestellte zur Ausbildung des Eckelementes führende Abwinklung 29 weist einen rechten Winkel auf. Gegebenenfalls kann der Winkel der Abwinklung 29 verschieden von 90° ausgebildet sein, um einen anderen Querschnitt des Türpfostens 22.1 entsprechend kundenspezifischer Anforderungen zu ermöglichen.The removable first door frame element 28.0 is preferably designed as a corner element. In the figure 3 The bend 29 shown leading to the formation of the corner element has a right angle. If necessary, the angle of the bend 29 can be designed to be different from 90° in order to allow a different cross section of the door post 22.1 according to customer-specific requirements.

Das erste Türrahmenelement 28.0 weist einen als Seitenkante ausgebildeten Seitenabschluss 54 auf und das zweite Türrahmenelement 28.1 weist ebenso einen als Seitenkante ausgebildeten Seitenabschluss 56 auf. Die Seitenkanten 54, 56 sind vorzugsweise parallel verlaufend und zueinander gering beabstandet, wenn das erste Türrahmenelement 28.0 durch das erste Befestigungselement 32 am zweiten Türrahmenelement 28.1 fixiert ist. Beispielhaft dargestellt ist in Figur 3 ebenso ein Türpfosten 40 der zur Aufzugskabine 6 gehörigen Kabinentür 16, wobei diese Aufzugskabine 6 an dem Stockwerk 18 angeordnet ist.The first door frame element 28.0 has a side closure 54 designed as a side edge and the second door frame element 28.1 also has a side closure 56 designed as a side edge. The side edges 54, 56 preferably run parallel and are slightly spaced apart from one another when the first door frame element 28.0 is fixed to the second door frame element 28.1 by the first fastening element 32. An example is shown in figure 3 likewise a door post 40 of the car door 16 belonging to the elevator car 6 , this elevator car 6 being arranged on the floor 18 .

In unmittelbarer Umgebung des ersten Befestigungselementes 32 trennen das erste und das zweite Türrahmenelement 28.0, 28.1 die Kammer 26 vom Innenraum des Aufzugsschachtes 4. Das erste Befestigungselement 32 umfasst ein als Stift 34 ausgebildetes Werkzeugelement. Beispielhaft ragt der Stift 34 in Richtung des Innenraumes des Aufzugsschachtes 4, so dass er bei der Anordnung der Aufzugskabine 6 am Stockwerk 18 nicht unmittelbar für Aufzugspassagiere zugänglich ist, da der Stift 34 zwischen den einseitig neben der Türöffnung angeordneten Türpfosten 22.1, 40 der Aufzugskabine 6 und der Schachttür 18 angeordnet ist. Mittels eines linealartigen Werkzeugs 50, welches in den Spalt zwischen die Türpfosten 22.1 der Kabinentür 16 und der Schachttür 18 geschoben werden kann, kann der Stift 34 des Befestigungselementes 32 derart parallel der Kanten 54, 56 des ersten und des zweiten Türrahmenelementes 28.0, 28.1 verschoben werden, dass das erste Türrahmenelement 28.0 vom zweiten Türrahmenelement 28.1 entfernbar ist. Gegebenenfalls ist durch dieses Verschieben des Befestigungselementes 32, das Befestigungselement 32 sowohl in seiner Verriegelten- als auch in seiner Freigabestellung nicht vom zweiten Türrahmenelement 28.1 lösbar, wie dies an späterer Stelle dieser Beschreibung näher erläutert wird. Das vorzugsweise stabförmig ausgebildete Befestigungselement 32 erstreckt sich in seiner Verriegeltenstellung entlang der Ausrichtung dieser Seitenkante 54.In the immediate vicinity of the first fastening element 32, the first and the second door frame element 28.0, 28.1 separate the chamber 26 from the interior of the elevator shaft 4. The first fastening element 32 comprises a tool element designed as a pin 34. For example, the pin 34 protrudes in the direction of the interior of the elevator shaft 4, so that it is not directly accessible to elevator passengers when the elevator car 6 is arranged on floor 18, since the pin 34 is located between the door posts 22.1, 40 of the elevator car 6 and the shaft door 18 is arranged. By means of a ruler-like tool 50, which can be pushed into the gap between the door post 22.1 of the car door 16 and the shaft door 18, the pin 34 of the fastening element 32 can be shifted parallel to the edges 54, 56 of the first and second door frame elements 28.0, 28.1 that the first door frame element 28.0 can be removed from the second door frame element 28.1. This shifting of the fastening element 32 may mean that the fastening element 32 cannot be detached from the second door frame element 28.1 either in its locked position or in its release position, as will be explained in more detail later in this description. The preferably rod-shaped fastening element 32 extends in its locked position along the alignment of this side edge 54.

Das erste Türrahmenelement 28.0 weist einen zweiten als Seitenkante ausgebildeten Seitenabschluss 54' auf. Das erste Türrahmenelement 28.0 kann darüber hinaus mittels eines zweiten Befestigungselementes 32' am zweiten Türrahmenelement 28.1 oder an einem weiteren nicht dargestellten Türrahmenelement des Türpfostens 22.1 befestigt sein. Das an das erste Türrahmenelement 28.0 angrenzende zweite bzw. weitere Türrahmenelement 28.1 weist eine Seitenkante 56' auf, die unmittelbar parallel der dem ersten Türrahmenelement 28.0 zugeordneten zweiten Seitenkante 54' angeordnet ist, wenn das zweite Befestigungselement 32' in seiner Verriegeltenstellung ist.The first door frame element 28.0 has a second side closure 54' designed as a side edge. The first door frame element 28.0 can also be fastened to the second door frame element 28.1 or to another door frame element (not shown) of the door post 22.1 by means of a second fastening element 32'. The second or further door frame element 28.1 adjoining the first door frame element 28.0 has a side edge 56' which is arranged directly parallel to the second side edge 54' associated with the first door frame element 28.0 when the second fastening element 32' is in its locked position.

Anstelle einer Verbindung des ersten Türrahmenelementes 28.0 mit dem zweiten bzw. weiteren Türrahmenelementes 28.1 mittels des zweiten Befestigungselementes 54' kann das erste Türrahmenelement 28.0 mit dem zweiten bzw. weiteren Türrahmenelement 28.1 mittels eines Scharnieres verbunden sein, so dass das erste Türrahmenelement 28.0 bei vorhandener Freigabestellung des ersten Befestigungselementes 32 in eine Öffnungsstellung geschwenkt werden kann. In dieser Öffnungsstellung des ersten Türrahmenelementes 28.0 ist die Kammer 26 bzw. die Steuereinheit 60 für einen Servicetechniker zugänglich. Vorzugsweise ist das Scharnier parallel der Seitenkanten 54, 56 ausgebildet.Instead of connecting the first door frame element 28.0 to the second or further door frame element 28.1 by means of the second fastening element 54', the first door frame element 28.0 can be connected to the second or further door frame element 28.1 by means of a hinge, so that the first door frame element 28.0 can be locked when the release position of the first fastening element 32 can be pivoted into an open position. In this open position of the first door frame element 28.0, the chamber 26 or the control unit 60 is accessible to a service technician. The hinge is preferably formed parallel to the side edges 54,56.

Ist das erste Befestigungselement 32 derart ausgebildet, dass es den Stift 34 umfasst und als Eckelement durch Ausbildung der Abwinklung 29 ausgebildet ist, ist es vorteilhaft, dass das zweite Befestigungselement ein von einem Stift 34 abweichendes Werkzeugelement einzusetzen, da Aufzugspassagiere unmittelbaren Zugang bzw. unmittelbare Sicht zu diesem bzw. auf diesen Stift hätten und derart das zweite Befestigungselement 32' manuell leicht aus seiner Verriegeltenstellung in seine Freigabestellung zu überführen. Statt des Stiftes 34 kann das Werkzeugelement demach als ein in dem Wandabschnitt 33, 33' ausgebildetes Loch 45' ausgebildet sein, welches durch einen Stab 50' oder ähnliches den Zweck erfüllendes Werkzeug bedienbar ist. Mittels des Stabes 50' ist das zweite Befestigungselement 32' aus seiner Verriegeltenstellung in seine Freigabestellung überführbar, wie dies bei dem ersten Befestigungselement 32 durch Betätigung des Stiftes 34 mittels des Werkzeuges 50 durchführbar ist.If the first fastening element 32 is designed in such a way that it encompasses the pin 34 and is designed as a corner element by forming the angled portion 29, it is advantageous for the second fastening element to use a tool element that differs from a pin 34, since elevator passengers have direct access or direct vision to this or onto this pin and in this way easily transfer the second fastening element 32' manually from its locked position to its release position. Instead of the pin 34, the tool element can thus be designed as a hole 45' formed in the wall section 33, 33', which can be operated by a rod 50' or similar tool fulfilling the purpose. The second fastening element 32' can be transferred from its locked position into its release position by means of the rod 50', as can be carried out in the case of the first fastening element 32 by actuating the pin 34 using the tool 50.
