  • Patent number: 11827492
    Abstract: Provided is a moving handrail that can lengthen its lifetime. The moving handrail includes: a handrail main body portion; a fabric arranged on a guide surface of the handrail main body portion and extending in a handrail longitudinal direction; and a resin sheet arranged on the fabric so that the fabric is sandwiched between the handrail main body portion and the resin sheet, wherein a surface of the fabric facing a handrail guide has arranged thereon an end portion of the fabric in the handrail longitudinal direction, and wherein the end portion of the fabric in the handrail longitudinal direction is covered with the resin sheet.
    Type: Grant
    Filed: March 4, 2020
    Date of Patent: November 28, 2023
    Assignee: MITSUBISHI ELECTRIC CORPORATION

  • Patent number: 11207814
    Abstract: A method of manufacturing an escalator handrail which has a composite material including a metallic steel wire and a thermoplastic resin, said metallic steel wire having a center elemental wire and a plurality of strands placed so as to surround the center elemental wire, including: a preheating step of heating the metallic steel wire; a composite-material forming step of integrating the metallic steel wire heated in the preheating step with the thermoplastic resin in a molten state to thereby form the composite material; and a cooling step of cooling the composite material formed in the composite-material forming step.

  • Patent number: 10399265
    Abstract: A method of manufacturing an escalator handrail of the invention is characterized by including: a metallic steel-wire producing step of placing a center elemental wire and a plurality of strands so that the plurality of strands surrounds the center elemental wire, and applying tension to them so that each distance between the center elemental wire and each of the strands becomes the same, to thereby produce the metallic steel wire; a preheating step of heating the metallic steel wire to a temperature equal to or more than that of a thermoplastic resin in a molten state; a composite-material forming step of integrating the metallic steel wire heated with the thermoplastic resin in a molten state, and extruding them through a die finished into a cross-section shape of the escalator handrail to thereby form the composite material; and a cooling step of forcibly cooling the composite material.

  • Patent number: 9290360
    Abstract: The endless escalator handrail is made up of a thermoplastic resin member having a first and a second curved portions and a joint section; a flat woven fabric bonded to an inner surface of the thermoplastic resin member; a first patch cloth having a base portion and a divergent portion, for being placed on the first curved portion side in the joint section; and a second patch cloth having a base portion and a divergent portion, for being placed on the second curved portion side in the joint section. The divergent potion of the first patch cloth is bonded onto the flat woven fabric at an inward side of the first curved portion, and the divergent potion of the second patch cloth is bonded onto the flat woven fabric at an inward side of the second curved portion.
