Embodiment Construction

[0032] Figures 1A-1C A first embodiment of the present invention is shown in . exist Figures 1A-1C The exemplary embodiment shown in is a conventional elevator installation 10 comprising an elevator car 11 , which is surrounded, carried and moved by a support mechanism 13 from below. The supporting mechanism 13 is arranged such that its two free ends are fixed in the elevator shaft 14 or on the elevator shaft 14 . Let F represent a fixed point. Starting from a first fastening point F, the support means 13 extends downwards along the elevator shaft 14 . The carrier 13 then wraps around the elevator car 11 from below, which has rollers 11.2. The support means 13 extends upwards on the other side of the elevator car 11 and surrounds a drive wheel 16 which is driven, for example, by an electric motor 15 . Starting from the drive wheel 16 , the carrier runs downward again, wraps around the counterweight roller 12 .

Abstract

The invention relates to an elevator installation (10) having a support mechanism (13) and a driven drive pulley (16) for driving an elevator car (11). The carrying mechanism (13) at least partially wraps around the driving wheel (16), and the carrying mechanism (13) includes a safety section (17), when the elevator car (11) or the counterweight (12) exceeds the upper position (X ) when approaching the shaft upper end (14.1), the setting of the safety section (17) should make the safety section (17) interact with the driving wheel (16). The structural shape of the safety section (17) is such that slippage occurs through the interaction between the drive wheel (16) and the carrying mechanism (13).

Description

technical field [0001] The invention relates to an elevator installation with a support means for driving an elevator car and to a support means. The invention also relates to a method for providing scalding protection in an elevator installation. Background technique [0002] The elevator installation has a support means for supporting and moving the elevator car. For this purpose, the carrier generally runs around a drive wheel driven by the drive. In most cases at least one counterweight is provided and once the drive unit moves the drive wheels, the elevator car and the counterweight move in opposite directions relative to each other. The traction between the drive wheel and the support means is designed in such a way that the drive wheel can convert the rotation into a movement of the support means without slipping, even when the elevator car is loaded. [0003] The elevator car of present elevator installations is lighter than conventional installations. The risk a...
