Antriebseinheit 13 mit einer Treibscheibe 14, über die mindestens ein Seil 19 geführt ist, das als Trag- und - Treibseil für die Aufzugskabine 2 bzw. das Gegengewicht 9 dient. Das Seil 19 ist kabinenseitig über eine erste Umlenkrolle 15 und eine zweite Umlenkrolle IS sowie gegengewichtsseitig über eine dritte Umlenkrolle 17 und eine vierte Umlenkrolle 18 geführt.Drive unit 13 with a traction sheave 14, over which at least one rope 19 is guided, which serves as a carrying and driving rope for the elevator car 2 or the counterweight 9. The cable 19 is guided on the cabin side via a first deflection roller 15 and a second deflection roller IS and on the counterweight side via a third deflection roller 17 and a fourth deflection roller 18.
Die Antriebseinheit 13 ist parallel zur ersten Seitenwand 1.2 und die Treibscheibe 14 ist quer zur ersten Seitenwand 1.2 angeordnet. Damit der Raum zwischen der ersten Seitenwand 1.2 und der Aufzugskabine 2 für Führungssschienen und Ahtriebseinheit optimal genutzt und klein gehalten werden kann, muss die Antriebseinheit.13 lang und schlank gebaut sein. Die Breite derThe drive unit 13 is parallel to the first side wall 1.2 and the traction sheave 14 is arranged transversely to the first side wall 1.2. In order that the space between the first side wall 1.2 and the elevator car 2 for guide rails and drive unit can be optimally used and kept small, the drive unit 13 must be long and slim.

Moreover ^ keep the elevator users during travel more in the front part of the elevator car. 2
Fig. 2 zeigt die erfindungsgemässe Aufzugsdisposition gemäss Fig. 1 aus der Richtung A gesehen. Die Antriebseinheit 13 ist auf einem Querträger 20 angeordnet, der von den Führungsschienen 4,5,10,11 getragen wird. Am Querträger sind auch ein erster Seilfi-xpunkt 21 und ein zweiter Seilfixpunkt 22 angeordnet. Das Seil 19 verläuft vom ersten Seilfixpunkt 21 über die 2. Umlenkrolle 16, weiter zur ersten Umlenkrolle 15, weiter über dieFIG. 2 shows the elevator disposition according to the invention according to FIG. 1 seen from direction A. The drive unit 13 is arranged on a cross member 20 which is supported by the guide rails 4,5,10,11. A first rope fixing point 21 and a second rope fixing point 22 are also arranged on the cross member. The rope 19 runs from the first fixed rope point 21 via the second deflection roller 16, further to the first deflection roller 15, further via the
Treibscheibe 14 und von dieser über die dritte Umlenkrplle 17 und anschliessend über die vierte Umlenkrolle 18 zum zweiten Seilfixpunkt 21. Der Seilverlauf schneidet den Kabinengrundriss nicht. Mit dem gezeigten Seilverlauf wird zwischen der Antriebseinheit 13 und der Aufzugskabine 2 eine Untersetzung von 2:1 erreicht. Für eine Bewegung der Aufzugskabine 2 bzw. des Gegengewichtes 9 von beispielsweise einem Meter muss die Antriebseinheit 13 mittels der Treibscheibe 14 zwei Meter Seil 19 bewegen. Anstelle der ersten Umlenkrolle 15 und der zweitenTraction sheave 14 and from this via the third deflection pulley 17 and then via the fourth deflection pulley 18 to the second fixed rope point 21. The course of the rope does not intersect the layout of the cabin. With the rope course shown, a reduction ratio of 2: 1 is achieved between the drive unit 13 and the elevator car 2. For a movement of the elevator car 2 or the counterweight 9 of, for example, one meter, the drive unit 13 must move two meters of rope 19 by means of the traction sheave 14. Instead of the first deflection roller 15 and the second
Umlenkrolle 16 kann nur eine seitlich der Aufzugskabine angeordnete Umlenkrolle vorgesehen sein. Anstelle der dritten Umlenkrolle 17 und der vierten Umlenkrolle 18 kann nur eine Umlenkrolle vorgesehen sein.Deflection roller 16 can only be provided a deflection roller arranged to the side of the elevator car. Instead of the third deflection roller 17 and the fourth deflection roller 18, only one deflection roller can be provided.
Mit den seitlich der Aufzugskabine 2 am Tragrahmen 3 angeordneten Umlenkrollen 15,16 kann wie in Fig. 2 gezeigt die Aufzugskabine 2 teilweise an der Antriebseinheit 13 vorbeifahren. Obwohl die Antriebseinheit 13 wesentlich tiefer als die Oberkante der Aufzugskabine 2 liegt, kann das oberste Stockwerk 8 bedient werden. Die Figuren 3 und 4 zeigen prinzipiell dieselbe Auf ugsdisposition wie die Figuren 1 und 2 mit dem Unterschied, dass der Seilverlauf kabinenseitig mit einer ersten Fixrolle 23 und gegengewichtsseitig mit einer zweiten Fixrolle 24 ergänzt worden ist. Die erste Fixrolle 23 ist im Seilverlauf zwischen der ersten Umlenkrolle 15 und der zweiten Umlenkrolle 16 am Querträger 20 angeordnet. Die zweite Fixrolle 24 ist im Seilverlauf zwischen der dritten Umlenkrolle 17 und der vierten Umlenkrolle 18 am Querträger 20 angeordnet. Mit dem gezeigten Seilverlauf wird zwischen der Antriebseinheit 13 und der Aufzugskabine 2 eine Untersetzung von 4:1 erreicht. Für eine Bewegung der Aufzugskabine 2 bzw. des Gegengewichtes 9 von beispielsweise einem Meter muss die Antriebseinheit 13 mittels der Treibscheibe 14 vier Meter Seil 19 bewegen. Ein 4:1 Seilverlauf wird für grössere Kabinenlasten verwendet.With the deflection rollers 15, 16 arranged on the side of the elevator car 2 on the support frame 3, the elevator car 2 can partially pass the drive unit 13 as shown in FIG. 2. Although the drive unit 13 is located much lower than the upper edge of the elevator car 2, the top floor 8 can be operated. FIGS. 3 and 4 show in principle the same opening arrangement as FIGS. 1 and 2, with the difference that the cable run has been supplemented with a first fixing roller 23 on the cabin side and with a second fixing roller 24 on the counterweight side. The first fixed roller 23 is arranged in the course of the cable between the first deflection roller 15 and the second deflection roller 16 on the cross member 20. The second fixed roller 24 is arranged on the cross member 20 in the course of the cable between the third deflection roller 17 and the fourth deflection roller 18. With the course of the cable shown, a reduction ratio of 4: 1 is achieved between the drive unit 13 and the elevator car 2. For a movement of the elevator car 2 or the counterweight 9 of, for example, one meter, the drive unit 13 must move four meters of rope 19 by means of the traction sheave 14. A 4: 1 rope course is used for larger cabin loads.

Diagonale der Grundfläche des Gegengewichtes 9. Damit wird der aussermittigen Führung des Gegengewichtes 9 Rechnung getragen. Die Führungselemente des Gegengewichtes 9 werden dadurch weniger belastet . Diagonal of the base of the counterweight 9. This takes account of the eccentric guidance of the counterweight 9. The guide elements of the counterweight 9 are thus less stressed.
