Problems solved by technology

[0003] The disadvantage of this known device is that the drive on the inside of the armrest is achieved by means of a drive belt
As soon as the belt tension relaxes, the drive of the handrail is no longer guaranteed due to the lack of friction on the idler pulley
In addition, due to the large wrap angle on the wheels, a large bending alternation of the armrest is required, and this will have an adverse effect on the life of the armrest

Embodiment Construction

[0025] figure 1 An escalator 1 is shown having a guardrail 1.1 with a handrail 2 on each side, wherein the guardrail 1.1 is supported by a guardrail seat. A ladder belt 1.3 with steps 1.4 for conveying personnel is connected with guardrail seats 1.2 on both sides. The handrail driving device 2.1 drives the handrail 2, wherein the friction wheel 3 drives the outer side 2.2 of the handrail 2 or the side of the handrail through friction fit. The inboard or sliding side roller 8 of the handrail 2 presses the handrail 2 against the friction wheel 3 . A drive wheel 4 arranged on the stepped sprocket 5 drives the friction wheel 3 in a friction fit or form fit manner. The step sprocket 5 moves the step chain 5.1 on which the steps 1.4 are arranged.

[0026] figure 1 5 to 5 show the frictional drive of the friction wheel 3 , wherein a frictional engagement exists between the drive wheel 4 and the friction wheel 3 .

Abstract

On this escalator (1) which has on each side a balustrade (1.1) with handrail (2) the balustrade (1.1) is held by a balustrade base (1.2). A step-band (1.3) which has steps (1.4) and transports persons abuts at the side against the balustrade base (1.2). A handrail-drive (2.1) drives the handrail (2) , a friction-wheel (3) driving the handrail (2) on the outside (2.2). On the inside (2.3) of the handrail (2), rollers (8) press the handrail (2) against the friction-wheel (3). A friction-wheel (4) arranged on a step chain-wheel (5) drives the friction-wheel (3) by frictional or mechanical engagement.

Description

technical field [0001] The invention relates to an escalator or moving walkway consisting of a truss, a step belt with steps or a plate belt with plates for transporting people and / or goods and a guardrail with handrails supported on each side by means of guardrail seats, Wherein the handrail driving device drives the handrail. Background technique [0002] An escalator is disclosed in EP0530946B1 in which the outer side of the handrail is guided on an unloaded wheel and the inner side of the handrail is guided on two driven wheels. The drive wheels are connected by a drive belt which presses the inside of the handrail against the unloaded wheels and drives the handrail. The driven wheels are driven by a step chain drive with a belt. [0003] A disadvantage of this known device is that the drive on the inside of the armrest is effected by means of a drive belt. As soon as the belt tension relaxes, the drive of the handrail is no longer guaranteed due to the lack of fricti...
