Problems solved by technology

[0003] In this and also in other devices of the same type, especially when the drive of the armrest is not positively locked but frictionally locked, there is the problem that the drive element is pressed onto the armrest sufficiently tightly so that when the armrest is driven No or as little slippage as possible between the element and the handrail
[0004] A further problem in such devices is the device-induced noise generation that occurs both in form-fitting and in force-fitting drive systems

Embodiment Construction

[0020] The device according to the invention is a drive unit which can be arranged at any desired point on a people conveyor, for example a horizontal and / or straight moving walk or an escalator. It can be seen that with the device according to the invention the handrail 1 can also be driven in the upper region of the guardrail 2 so that no additional space is required below the return section of the handrail which runs in the lower region of the guardrail. It goes without saying, however, that the device according to the invention can also be rotated by 180° for driving the return section of the return.

[0021] In the embodiment shown, the armrest 1 has a substantially C-shaped cross section, wherein a web 3 is arranged in the inner central region of the armrest 1 . The lug 3 can theoretically have toothing for engaging the drive element 4 in a form-fitting manner, but in the present invention is preferably continuous and is therefore only driven by the drive element 4 in a ...

Abstract

A device for driving a handrail (1) of a people conveyor, said device comprising a recirculating drive element (4) driven by a motor (11). A support roller (7) is arranged on the side of the drive element (4) opposite the handrail (1), and the drive element (4) is supported on the support roller (7) via a belt (9).

Description

technical field [0001] The invention relates to a device for driving a handrail of a people conveyor, said device comprising a recirculating drive element driven by a motor. Background technique [0002] Such a device is known, for example, from DE 112006004175T5. [0003] In this and also in other devices of the same type, especially when the drive of the armrest is not positively locked but frictionally locked, there is the problem that the drive element is pressed onto the armrest sufficiently tightly so that No or as little slippage as possible between the element and the handrail. [0004] A further problem with devices of this type is the device-induced noise generation that occurs both in form-fitting and non-positive-fitting drive systems. Contents of the invention [0005] The object of the present invention is to eliminate these problems as much as possible. [0006] This object is achieved in a device of the type mentioned at the outset in that a support roll...
