Abstract
A curvature-adjustable handrail length compensation device for an escalator or a moving walkway is provided. The device comprises a frame, handrail support mounted along a length of the frame, and springs mounted to the frame to elastically support the handrail support. Each handrail support includes a supporting rod movably mounted through the frame, a first supporting roller mounted to an end of the supporting rod to support the handrail, and a stopper formed at the other end of the supporting rod. The spring is provided between the frame and the first supporting roller, and biases the first supporting roller away from the frame.

A curvature-adjustable handrail length compensation device, comprising:
- a frame;
- a plurality of handrail supports mounted along a length of the frame, each handrail support comprising at least one roller;
- and
- a plurality of springs between a corresponding roller and the frame to elastically support each of the plurality of handrail supports so that each of the handrail supports move independently up and down.
A curvature-adjustable handrail length compensation device, comprising:
- a handrail support mountable along a length of a frame;
- the handrail support comprising a movable supporting rod;
- a first supporting roller mounted to one end of the supporting rod and a stopper formed at the other end of the supporting rod;
- a spring disposed between the first supporting roller and the stopper to elastically support the first supporting roller;
- a second supporting roller disposed relative to the first supporting roller so that a handrail is movable therebetween;
- and
- wherein the first supporting roller and the second supporting roller are mounted to the same supporting rod.
A passenger conveyor handrail assembly, comprising:
- a handrail;
- a frame;
- a plurality of handrail supports mounted along a length of the frame, each handrail support comprising at least one roller that directly contacts the handrail and provides support to the handrail;
- and
- a spring associated with each handrail support to elastically support the associated handrail support so that each of the handrail supports is moveable relative to the frame independently of the other handrail supports.
