Abstract
An elevator belt for an elevator installation includes a belt body in which a tensile carrier arrangement with several tensile carriers for transmission of a tension force in a longitudinal direction of the elevator belt is arranged. A profile body which spaces these tensile carriers from one another is arranged between adjacent tensile carriers of the tensile carrier arrangement.
Claims19
An elevator belt for an elevator installation, comprising:
- a belt body in which a plurality of tensile carriers formed as strands or cables for transmission of a tension force in a longitudinal direction of the elevator belt is arranged;
- and
- wherein a plurality of discrete profile bodies is embedded in the belt body and extends in the longitudinal direction of the elevator belt, each of said profile bodies is arranged between adjacent tensile carriers and spaces said adjacent tensile carriers from one another, said belt body, said tensile carriers, and said profile bodies are formed from different materials from each other and at least two of said profile bodies having different cross-sectional shapes from each other.
An elevator belt for an elevator installation, comprising:
- a belt body in which a plurality of tensile carriers formed as strands or cables for transmission of a tension force in a longitudinal direction of the elevator belt is arranged in a common plane;
- and
- wherein a plurality of discrete profile bodies is embedded in the belt body and extends in the longitudinal direction of the elevator belt, each of said profile bodies is arranged between adjacent ones of said tensile carriers and spaces said adjacent tensile carriers from one another, said belt body, said tensile carriers, and said profile bodies are formed from different materials from each other, said profile bodies having circular cross-sectional shapes with at least two of said profile bodies having different diameters from each other.
An elevator belt for an elevator installation, comprising:
- a belt body in which a plurality of tensile carriers formed as strands or cables for transmission of a tension force in a longitudinal direction of the elevator belt is arranged in a common plane;
- and
- wherein a plurality of discrete profile bodies is embedded in the belt body and extends in the longitudinal direction of the elevator belt, each of said profile bodies is arranged between adjacent ones of said tensile carriers and spaces said adjacent tensile carriers from one another, said belt body, said tensile carriers, and said profile bodies are formed from different materials from each other, said belt body having on a rear side, which is opposite a traction side for engagement with a drive wheel, a back layer formed from a thermoplastic synthetic material, and said tensile carriers and said profile bodies bear against said back layer
- wherein one of a) at least two of said profile bodies have a circular cross-sectional shape, the shapes being of different diameters from each other, and b) at least two of said profile bodies have different cross-sectional shapes from each other.
