Abstract
The invention encompasses a handrail for escalators or moving walkways that includes a grip piece of a thermoplastic elastomer including soft segments and hard segments and optionally a sliding layer arranged on the underside of the grip piece relative to the mounting orientation of the handrail. A ratio of the proportions of the soft segments to the hard segments is selected from a range with a lower limit of 1:1 and an upper limit of 9:1, or, in a variation, from a range with a lower limit of 1.5:1 and an upper limit of 6:1, or, in another variation, from a range with a lower limit of 2.5:1 and an upper limit of 4:1.
Claims45
A handrail for escalators or moving walkways, said handrail comprising:
- a grip piece comprising a thermoplastic elastomer having macromolecules;
- said thermoplastic elastomer comprising soft segments and hard segments in the macromolecules;
- a ratio of proportions of the soft segments to the hard segments comprising a ratio selected from a range having a lower limit of equal to or greater than 1:1 and an upper limit of equal to or less than 9:1.
A handrail according to 1, wherein:
- at least one tensile carrier is embedded in the grip piece.
A handrail for escalators or moving walkways, said handrail comprising:
- a grip piece comprising a thermoplastic elastomer;
- said thermoplastic elastomer comprising soft segments and hard segments;
- a ratio of proportions of the soft segments to the hard segments comprising a ratio selected from a range having a lower limit of equal to or greater than 1:1 and an upper limit of equal to or less than 9:1;
- the thermoplastic elastomer being a thermoplastic polyurethane block copolymer at least comprising monomer units A and B, e.g., a diblock copolymer ([AB]n), a triblock copolymer (An-Bm-An), a segment copolymer ([Aa-Bb]n), a star block copolymer ([An-Bm]XX where x>2).
