Definitions

  • the present invention relates to high-speed-incline escalators in which the steps move faster in the escalator intermediate inclined section than in the upper and lower horizontal sections.
  • JP-A-2002326780 is related to an escalator as described in the preamble of claim 1.
  • an escalator with a high-speed inclined section which can reduce escalator riding time by moving the steps in the intermediate inclined section at a relatively higher speed than the movement speed of the steps in the upper and lower horizontal sections where the passengers get on and off (see Patent document 1).
  • a conventional escalator with a high-speed inclined section as described in Patent document 1 has a configuration in which the steps run on an approximately arcuate track in the reversing section with foldable links (folding links) for connecting the steps being extended, wherein there has been a problem in that because the trajectory along which the driving rollers should travel does not match the shape of the reversing-section track, enormous travel resistance or the like arises between the driving rollers and the track, whereby smooth reversing operation of the steps cannot be achieved.
  • the invention has been made to resolve such a problem, and aims to provide an escalator with a high-speed inclined section in which a smooth reversing movement can be achieved by passing the folding links through the reversing section while folding and extending them.
  • An escalator with a high-speed inclined section relevant to the invention includes: a plurality of steps, each step having a driving roller and a trailing roller, and being connected together in an endless fashion for circulation;
  • the link mechanism moves with the first link and the second link being folded, and when the step passes through the reversing sections, the link mechanism moves with the first link and the second link that have been folded gradually being extended.
  • Fig. 1 is an overall side view illustrating an escalator with a high-speed inclined section according to Embodiment 1 of the invention
  • Fig. 2 is an explanatory diagram illustrating the portion around a horizontal section and a reversing section at the upstairs end of the escalator.
  • Amain frame 1 is provided with a driving-roller track 2, a trailing-roller track 3, and an auxiliary-roller track 4. Steps 5 are connected together in an endless fashion, and circulated along the tracks 2 through 4.
  • Each of the steps 5 has a driving roller 11 that rolls along the driving-roller track 2, a driving-roller shaft 12 that supports the driving roller 11, a trailing roller 13 that rolls along the trailing-roller track 3, and a trailing-roller shaft 14 that supports the trailing roller 13; and is configured with a tread 6 for carrying a passenger and a riser 7 extending downwards from the underside of the tread 6.
  • the speed of the steps 5 varies by the distance between adjacent steps 5-in other words, the distance between the driving-roller shafts 12 (distance between the centers of the shafts)-being changed. More specifically, in an upper landing section A 1 where passengers get on or off, the distance between the centers of the adjacent driving-roller shafts 12 is decreased, and the steps 5 move at low speed.
  • the link mechanism 20 includes first through fifth links 21 through 25, and an auxiliary roller 15 that rolls along the auxiliary-roller track 4.
  • One end portion of the first link 21 is rotatably connected to the driving-roller shaft 12.
  • the other end portion of the first link 21 is rotatably connected to the middle portion of the fifth link 25 via a rotational shaft 28.
  • One end portion of a second link 22 is rotatably connected to the driving-roller shaft 12 of the adjacent step 5.
  • the other end portion of the second link 22 is rotatably connected to the middle portion of the fifth link 25 via the rotational shaft 28.
  • a third link 23 is rotatably connected to the middle portion of the first link 21.
  • a fourth link 24 is rotatably connected to the middle portion of the second link 22.
  • the other end portions of the third link 23 and the fourth link 24 are connected to one end portion of the fifth link 25 via a sliding shaft 29.
  • a guide groove for guiding the sliding of the sliding shaft 29 in the fifth link 25 is provided in the one end portion of the fifth link 25.
  • the rotatable auxiliary roller 15 is provided at the other end portion of the fifth link 25.
  • the first, second, third, and fourth links 21, 22, 23, and 24 form a so-called pantograph type quadruple link mechanism, in which the angle made by the first and the second links 21 and 22 can be increased or decreased with the fifth link 25 serving as the axis of symmetry.
  • the link mechanism operates like the framework of an umbrella when being opened out, and the distance between the driving-roller shafts 12 of the adjacent steps, which has been minimum at the upper landing section A 1 , gradually increases.
  • the distance between the driving-roller track 2 and the auxiliary-roller track 4 becomes minimum, and the distance between the driving-roller shafts 12 of the adjacent steps 5 becomes maximum. Therefore, the speed of the steps 5 reaches maximum, and the first and the second links 21 and 22 become approximately linear in this state.
  • the first link 21 and the second link 22 in the link mechanism 20 connecting the driving-roller shafts 12 of the adjacent steps are folded in the upstairs landing section A 1 where the steps move at low speed, and within the upstairs expanding section A 2 from the landing section up to the reversing section F, the first link 21 and the second link 22 in the link mechanism are gradually extended linear. Then the links move to the reversing section F.
  • the driving-roller track 2 of the upstairs reversing section F has no moving parts and is arcuate in shape, and if the first link 21 and the second link 22 move along the reversing section F in an extended state, because the movement trajectory of the driving roller 11 and the shape of the fixed arcuate driving-roller track 2 do not match in shape, enormous travel resistance or the like arises between the driving roller 11 and the driving-roller track 2, whereby smooth reversing operation of the steps 5 cannot be achieved.
  • the first link 21 and the second link 22 in the link mechanism 20 that connect the respective driving-roller shafts 12a and 12b are folded in the reversing section when the adjacent steps 5 move along the reversing section.
  • the link mechanism 20 and the driving-roller track 2 are established so that their positional relationship is one in which the centers of the driving-roller shafts 12a and 12b would pass outside of the driving-roller track 2 in the reversing section when the first link 21 and the second link 22 pass through the reversing section while being extended linear, by decreasing the distance between the center of the driving-roller shaft 12a and the center of the driving-roller shaft 12b, the center of the driving-roller shaft 12a and the center of the driving-roller shaft 12b that would be positioned outside of the circular arc can be displaced conversely toward the inside of the circular arc, and the center of the driving-roller shaft 12a and the center of the driving-roller shaft 12b can be kept within the track range of the circular driving-roller track 2 in the reversing section F.
  • the first link 21 and the second link 22 in the link mechanism 20 shouldbe folded or extended. This can be achieved also in the reversing section F by appropriately varying the distance between the auxiliary-roller track 4 and the arcuate driving-roller track 2 as well as in the upstairs curved section B or in the upstairs expanding section in the escalator with a high-speed inclined section when controlling the folding and extending of the first link 21 and the second link 22 in the link mechanism 20.
  • the movement trajectory of the driving roller and the shape of the driving-roller guide track can be matched, whereby the smooth reversing operation of the steps can be achieved.
  • Fig. 3 is an explanatory diagram illustrating the portion around a horizontal section A and a reversing section F at the upstairs end of an escalator with a high-speed inclined section according to Embodiment 2 of the invention. Redundant descriptions of components and their operations illustrated in Fig. 3 that are identical to those in Fig. 2 will be omitted by attaching identical numerals.
  • the link mechanism 20 is configured with the first through fifth links as illustrated in Fig. 2 .
  • the link mechanism 20 is configured only with a first link 21 and a second link 22 as illustrated in Fig. 3 . Operations and benefits are the same as in Embodiment 1.
  • Fig. 4 is an explanatory diagram illustrating the portion around a horizontal section A and a reversing section F at the upstairs end,of the escalator with a high-speed inclined section according to Embodiment 3 of the invention. Redundant descriptions of components and their operations illustrated in Fig. 4 that are identical to those in Fig. 2 will be omitted by attaching identical numerals.
  • a driving-roller track 2 of the upstairs reversing section F in Fig. 4 has no moving parts, and is arcuate in shape.
  • the distance between adjacent steps 5 is minimum in the horizontal section A forward path, and the distance between the adjacent steps 5 is maximum in the horizontal section A return path.
  • the steps 5 move along the reversing section F, the distance between the steps 5 is gradually increased from the horizontal section forward path toward the horizontal section return path.
  • the distance between the driving-roller track 2 and the auxiliary roller 4 is maximum in the horizontal section forward path with the first link 21 and the second link 22 in the link mechanism 20 being folded; the distance between the driving-roller track 2 and the auxiliary-roller track 4 is minimum in the horizontal section return path with the first link 21 and the second link 22 being linear; and the distance between the driving-roller track 2 and the auxiliary roller 4 is gradually decreased from the horizontal section forward path to the horizontal section return path in the reversing section F; whereby the folding and extending of the first link and the second link is controlled in the same way as in the upstairs curved section B or in the upstairs extending section in the escalator with a high-speed inclined section.
  • step reversing sections at the upstairs end and at the downstairs end smooth reversing operation of the steps can be achieved.
  • the escalator with a high-speed inclined section can be reduced, the escalator with a high-speed inclined section can be produced at low cost, and the construction cost can be reduced.
  • first link and the second link are extended or folded in the reversing section in the escalator with a high-speed inclined section according to the invention as above, even if the driving-roller guide track in the reversing section is simply arcuate in shape, smooth reversing operation of the steps can be achieved so that energy saving and ride quality are enhanced.
