Embodiment Construction

[0023]figure 1 An elevator installation 1 is shown with at least one elevator car frame 2 , which can be traveled in a travel space 3 provided for the travel of the elevator car frame 2 . For example, the travel space 3 can be arranged in an elevator shaft of a building.

[0024] The elevator car support 2 is suspended on the traction mechanism 6 through the sheaves 4,5. Alternatively, the elevator car support 2 can also be suspended from the traction mechanism 6 via a single centrally arranged sheave. The traction means 6 is also guided around the drive pulley 7 of the drive mechanical unit 8 . The drive mechanical unit 8 is arranged in the elevator shaft. Depending on the momentary direction of rotation of the drive pulley 7 , the elevator car frame 2 travels upwards or downwards through the travel space 3 .

[0025] A first elevator cage 10 and a second elevator cage 11 are arranged adjustably on the elevator cage support 2 . Here, the first elevator car 10 is arranged ...

Abstract

The invention relates to an elevator installation (1) with an elevator car frame (2), which can be moved in a travel space (3) provided for the travel of the elevator car frame (2). Furthermore, a first elevator car (10) and a second elevator car (11) are provided, which are arranged adjustable on the elevator car support (2) and have a drive arranged on the elevator car support (2) unit (14). Furthermore, an adjusting device (40) is provided, which has a first traction means (22) and a second traction means (23), which are guided in opposite directions around a drive wheel (15) drivable by a drive unit (14). Here, the distance ( 47 ) between the first elevator cage ( 10 ) and the second elevator cage ( 11 ) can be adjusted by reversing the movement of the elevator cages ( 10 , 11 ). Adaptation to different floor spacings is thereby achieved.

Description

technical field [0001] The invention relates to an elevator installation having at least one elevator car frame, which can accommodate at least two elevator cars. The invention relates in particular to the field of elevator installations designed as so-called double-deck elevator installations. Background technique [0002] JP2007-331871A discloses a double deck elevator. The disclosed elevator includes a car frame in which two cars are stacked vertically. The two cages are supported here in each case on a frame with sheaves. Furthermore, a drive unit is arranged on the car frame, around which the hoisting ropes are guided. The hoisting ropes are guided on the one hand around the sheaves of the frame for one elevator car and on the other hand around the sheaves of the frame of the other elevator car. The elevator car suspended in this way can be raised or lowered relative to the car frame by actuating the hoisting ropes by means of the drive unit. This enables the two e...
