Definitions

  • the present invention relates to an escalator for transporting passengers according to the preamble of claim 1.
  • the JP-A-57-141378 discloses a handrail driving mechanism of a man conveyer that the total width of the man conveyer is decreased to improve the maintainability by forming a part of the conveyer main frame by a support frame of the handrail driving mechanism, and by arranging a coupling mechanism between a driving roller and a motor in the same space facing moving step tread.
  • the JP-A- 57-141379 discloses a man conveyer that the total width of the man conveyer is decreased to reduce the installation space by separating the man conveyer main frame at a portion of the handrail driving mechanism, and by welding and integrating a support frame of the handrail driving mechanism to and with the separated portion to form a part of the main frame.
  • the JP-A- 51-139082 discloses an escalator that the inner side surface of the balustrade is formed in a convex shape projecting toward the step tread so that a passenger's foot may be kept apart from the skirt guard.
  • balustrade has a vertical side wall and at the upper end of said side wall the handrail guiding member is fixed. At the lower end portions of the balustrades are mounted inner decks. The horizontal distance between the both vertical balustrades is smaller than the horizontal distance between the handrails.
  • balustrades each of which is vertically arranged under an endlessly continuous handrail, to support the handrail are arranged in parallel to each other so that the distance between the both balustrades in the vertical direction becomes constant, or are arranged so that the distance between the both balustrades in the lower side of the balustrade is shorter than the distance between the both balustrades at positions near the upper-line tracks of the handrails. Therefore, for example, a passenger carrying baggage with him sometimes leans against the balustrade due to braking caused by the baggage.
  • the JP-A-9-323 884 discloses a passenger escalator comprising a row of endlessly connected steps, two balustrades upstanding along both sides of the step row and endless handrails supported and guided on upstanding support rails.
  • the balustrades have a box-like structure and comprise a vertical outer side wall, a tilted inner side wall and a horizontal upper wall on which the supporting rails are fixed.
  • the horizontal distance between the both handrails is larger than or substantially equal to the horizontal distance between the lower end portions of the inner side walls of the both balustrades.
  • the width of the steps is substantially equal to the horizontal distance of the lower end portions of said inner side walls.
  • the lower end portion of the side wall is connected with an outside scirt guard and protruding toward the space corresponding to the moving footstep width.
  • a lighting system is sprovided on the slant surfact of said tilted lower portion of the sidewall for illuminating the end top of the foot steps.
  • An object of the invention is to provide a passenger escalator which can extend the width of the space between the balustrades.
  • Another object of the invention is to provide a passenger escalator which can widen the width of step tread, and thereby the width of the space between the balustrades can be extended.
  • the passenger escalator comprises the features of claim 1.
  • said safe passenger escalator in which the balustrades are arranged in the outer side of the machine room, and a hand rail support portion is provided on the side surface of the upper end portion of the balustrade which is arranged so as to, for example, tilt or curve toward the step side from the upper portion of the machine room or so as to vertically stand, and an upper-line track of the handrail is arranged in the top end portion of the support portion.
  • the handrail transport roller is arranged in the outer side and the driving unit of the transfer roller is arranged in the step side.
  • the step tread portion and the riser portion of the step can be extended in the width direction, and the balustrades can be arranged in a state of tilting toward the step side in the upper portion (a state of broadening downward), and accordingly, the space in the lower portion of the passenger's riding space is increased compared to that in the conventional passenger escalator. Therefore, even when a passenger carries baggage with him, the passenger does not lose his balance by being blocked by the baggage. Further, a little child can not mischievously enter the outer deck portion. Thus, a safe passenger escalator can be provided.
  • a return track of the handrail of which the upper-line track is formed along the upper surface of the balustrade In a portion further below the upper-line track of the step and the return track of the step, there is arranged a return track of the handrail of which the upper-line track is formed along the upper surface of the balustrade.
  • the step can be extend in the width direction by that amount, and the balustrades can be arranged in a state of tilting toward the step side in the upper portion (a state of broadening downward), and accordingly, the space in the lower portion of the passenger's riding space is increased compared to that in the conventional passenger escalator. Therefore, for example, when a passenger carries baggage with him, the passenger does not lose his balance by being blocked by the baggage. Further, a little child can not mischievously enter the outer deck portion. Thus, a safe passenger escalator can be provided.
