Abstract
Handrail having laterally bent edges which engage around laterally projecting ribs of a guide element such that the ends of the bent edges are situated at a clear distance from one another and each at a distance from a guide base of the guide element where the clear distance corresponds to a total gap size plus a width of the guide base and is chosen in consideration of the width of the guide base and the shrinkage and warpage phenomena occurring during operation to not exceed 8 mm, while a clear width of the bent edges is chosen to be greater than the width of the guide element at the ends of the laterally projecting ribs such that, considering tolerances of the width of the guide element at the ends of the ribs and the shrinkage and warpage phenomena occurring during operation of the handrail, not exceed 8 mm.
