Der Rahmen weist unterhalb der Decke des oberen Stockwerkes eine aus Querbalken bestehende Bühne für Elektromotor, Aufzugswinde und Schaltanlage auf. Die Aufzugskabine gleitet auf Laufrollen an den Innenseiten von Winkeleisen des Rahmens. Die Aufzugsseile werden über zwei Umlenkrollen, die sich auf der Höhe der Bühne befinden einer Seiltrommel zugeführt und gegenläufig auf- bzw. abgewickelt.From the utility model DE-GM 88 07 219 is one Elevator became known with a from the bottom of the lower floor to the ceiling of the upper floor reaching frame as a guide element of an elevator car. The frame points below the ceiling of the upper floor a cross-beam stage for the electric motor, Elevator winch and switchgear. The elevator car slides on rollers on the inside of angle iron of the frame. The elevator ropes are over two Deflection pulleys that are at the level of the stage fed to a rope drum and opened or closed in opposite directions settled.

Ein Nachteil der bekannten Einrichtung liegt darin, dass sich die Anordnung der Antriebseinheit und die Seilführung nicht für eine Aufzugsanlage mit einem Gegengewicht eignet. Weiter nachteilig ist, das die unterhalb der Decke angeordnete Antriebseinheit mit Motor und Aufzugswinde sowie Schaltanlage für Unterhaltsarbeiten nur mit Mühe erreichbar sind.A disadvantage of the known device is that the arrangement of the drive unit and the cable guide not suitable for an elevator system with a counterweight. Another disadvantage is that the below the ceiling arranged drive unit with motor and elevator winch and switchgear for maintenance work with difficulty are reachable.

The invention, as characterized in claim 1 solves the problem to avoid the disadvantages of the known device and to create an elevator system with a drive unit, which can be arranged in a space-saving manner in the elevator shaft and is easily accessible.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass die Aufzugsanlage keinen Maschinenraum benötigt, wodurch die üblicherweise notwendigen und kostspieligen Dachaufbauten oder Kellerräume für den Maschinenraum entfallen. Weiter vorteilhaft ist, dass minimale Schachtabmessungen insbesondere im Überfahrbereich möglich sind. Ein weiterer entscheidender Vorteil ist, dass die Aufzugsanlage unabhängig von der Bausubstanz und von der Tragkraft der Schachtdecke ist, weil die erfindungsgemässe Aufzugsanlage lediglich einen selbsttragenden Aufzugsschacht benötigt.The advantages achieved by the invention are in essential to see that the elevator system none Engine room needed, which is the usual necessary and expensive roof structures or Basement rooms for the machine room are eliminated. Further It is advantageous that minimal shaft dimensions are possible in particular in the drive-over area.
