Figur 1 zeigt einen schematischen Längsschnitt durch einen Schachtraum 11, der durch im wesentlichen parallel zueinander angeordnete Schachtwände 12a, 12b, sowie einen. Schachtboden 18 und eine Schachtdecke 13 begrenzt ist. In dem Schachtraum 11 ist eine Kabine 10 des Aufzuges angeordnet, die dem Personentransport dient. Der sich über mehrere Stockwerke erstreckende Schachtraum 11 weist in der Zeichnung nicht dargestellte in den jeweiligen Stockwerken angeordnete Schachtraumtüren auf, die von der Kabine 10 angefahren werden können.Figure 1 shows a schematic longitudinal section through a shaft room 11, the one arranged essentially parallel to one another Shaft walls 12a, 12b, and one. Pit floor 18 and one Manhole cover 13 is limited. In the shaft room 11 there is a cabin 10 of the elevator arranged, which serves to transport people. The Chimney 11 extending over several floors points in the drawing, not shown, arranged in the respective floors Chess room doors that are approached by the cabin 10 can.

Der Aufzug weist zum Verfahren der Kabine eine Antriebseinheit 19 auf, die im oberen Bereich des Schachtraumes 11, im sogenannten Schachtkopf, angeordnet ist. Die Antriebseinheit 19 weist einen Antriebsmotor 21 auf, dessen Antriebswelle eine Seilscheibe 20 antreibt. Zur Lagerung der Antriebseinheit 19 sind zwei parallel zueinander angeordnete Träger 22 vorgesehen, deren Endbereiche an gegenüberliegenden Schachtwänden festgelegt sind.The elevator has a drive unit 19 for moving the cabin on, in the upper area of the shaft room 11, in the so-called Shaft head, is arranged. The drive unit 19 has a drive motor 21, whose drive shaft drives a pulley 20. To mount the drive unit 19, two are arranged parallel to each other Carrier 22 is provided, the end regions of which lie on opposite sides Shaft walls are defined.

Die Kabine 10 wird von einem Satz von Tragseilen 14 getragen, von dem lediglich ein Tragseil 14 in der Zeichnung schematisch dargestellt ist. Das Tragseil 14 weist ein erstes Ende auf, das im Bereich der Schachtwand 12b an einem im oberen Schachtbereich angeordneten Anker 29 festgelegt ist. Ausgehend von dem Anker 29 verläuft das Tragseil 14 über am Boden 10a der Kabine 10 vorgesehene Umlenkrollen 30a, 30b, zu der von dem Antriebsmotor 21 angetriebenen Seilscheibe 20. Nach Umschlingung der Seilscheibe 20 verläuft das Tragseil 14 zu einer Gegengewichts-Umlenkrolle 16, die an dem Gegengewicht 15 festgelegt ist. Nach Umschlingung der Gegengewichts-Umlenkrolle 16 verläuft das Tragseil 14 wieder zu einem in der Zeichnung nicht dargestellten im oberen Schachtbereich angeordneten Anker.The cabin 10 is supported by a set of suspension ropes 14 from which only a suspension cable 14 is shown schematically in the drawing is. The support cable 14 has a first end, which in the area of the Shaft wall 12b arranged on one in the upper shaft area Anchor 29 is set. Starting from the anchor 29 that runs Support rope 14 via deflection rollers provided on the floor 10a of the cabin 10 30a, 30b, to the sheave driven by the drive motor 21 20. After wrapping the rope pulley 20 that runs Support cable 14 to a counterweight pulley 16, which is attached to the counterweight 15 is set. After wrapping the counterweight pulley 16, the suspension cable 14 runs again to one in the drawing Anchors, not shown, arranged in the upper shaft area.

Wie aus Figur 2 ersichtlich ist, wird die Kabine 10 an zwei in Längsrichtung des Schachtraumes 11 verlaufenden Führungsschienen 28 geführt. Auch das Gegengewicht 15 ist an nicht näher dargestellten Führungsschienen geführt. Aus dieser Ansicht ist auch besonders gut ersichtlich, daß die Achse 23 des Antriebsmotors 21 im wesentlichen senkrecht zur Schachtwand 12a angeordnet ist. Die Seilscheibe 20 ist demgegenüber parallel zu der Schachtwand 12a positioniert.As can be seen from Figure 2, the cabin 10 at two in the longitudinal direction of the shaft space 11 extending guide rails 28 guided. The counterweight 15 is also not shown Guided rails. From this view it is also particularly good it can be seen that the axis 23 of the drive motor 21 essentially is arranged perpendicular to the shaft wall 12a. The pulley 20 is in contrast, positioned parallel to the shaft wall 12a.

Nachdem die Antriebseinheit 19 in einem oberen Bereich des Schachtraumes 11 angeordnet ist, der nicht von der Kabine 10 überfahren wird, können die Abmessungen der Kabine 10 derart gewählt werden, daß im wesentlichen der ganze Querschnitt des Schachtraumes 11 ausgenützt wird. Weiterhin ergibt sich eine gute Ausnutzung der Schachthöhe ohne zusätzliche Sicherheitsabstände dadurch, daß die Kabine 10 ein Dach 10b aufweist, in dem eine mittels einer Klappe 27 verschließbare Dachöffnung 24 vorgesehen ist. Um mißbräuchliches Öffnen zu vermeiden, ist der Klappe 27 eine Entriegelungseinrichtung 32 zugeordnet, die vor unberechtigtem Zugriff gesichert ist. Damit wird vermieden, daß Fahrgäste die Klappe 27 öffnen und während der Fahrt aus der Kabine 10 aussteigen. Beispielsweise kann die Entriegelungseinrichtung 32 mit einer im Schaltkasten des Aufzuges angeordneten Schalteinrichtung gekoppelt sein, die nur für den Monteur 25 zugänglich ist.After the drive unit 19 in an upper area of the shaft room 11 is arranged, which is not run over by the cabin 10 the dimensions of the cabin 10 can be chosen such that essentially the entire cross section of the shaft space 11 is exploited. Furthermore, there is good utilization of the Shaft height without additional safety clearances in that the Cabin 10 has a roof 10b, in which one by means of a flap 27 closable roof opening 24 is provided. Abusive To avoid opening, the flap 27 is an unlocking device 32 assigned, which is secured against unauthorized access. In order to is avoided that passengers open the flap 27 and during the Get out of the cabin 10. For example, the unlocking device 32 with one arranged in the control box of the elevator Switching device can be coupled that only for the fitter 25 is accessible.
