Definitions

  • the present invention relates to a high-speed inclined portion escalator in which a traveling speed of steps in an intermediate inclined portion is faster than a traveling speed of the steps in an upper landing portion and a lower landing portion.
  • high-speed inclined portion escalators have been proposed in which it is possible for the amount of time spent riding the escalator to be shortened by operating at low speed in upper and lower landing portions where the passengers get on and off, operating to accelerate and decelerate in an upper curved portion and a lower curved portion, and operating at high speed in an intermediate inclined portion.
  • Ahigh-speed inclined portion escalator of this kind is disclosed in Japanese Patent Laid-Open No. SHO 51-116586 (Gazette), for example.
  • Figure 8 is a schematic side elevation showing an example of a conventional high-speed inclined portion escalator.
  • a plurality of steps 2 linked endlessly are disposed on a main frame 1.
  • the steps 2 are driven by a drive unit (a step driving means) 3, and are moved cyclically.
  • a pair of railings 4 are disposed upright on an upper portion of the main frame 1.
  • the railings 4 are disposed on both sides in a width direction of the steps 2.
  • Main tracks 5 forming a cyclic path for the steps 2, trailing tracks 6 for controlling an attitude of the steps 2, and auxiliary tracks 7 for changing a pitch between adjacent steps 2 are disposed on the main frame 1.
  • Moving handrail apparatuses 25 are disposed on the railings 4.
  • the moving handrail apparatuses 25 have endless moving handrails 26 that are moved cyclically.
  • the cyclic path for the steps 2 has: a forward section, a return section, an upper inversion portion, and a lower inversion portion.
  • the forward section of the cyclic path has: an upper landing portion (an upper horizontal portion) A, an upper curved portion B, an intermediate inclined portion (a constant inclination portion) C, a lower curved portion D, and a lower landing portion (a lower horizontal portion) E.
  • Figure 9 is a side elevation showing a vicinity of the upper landing portion in Figure 8 enlarged.
  • the steps 2 have: a tread 8 for carrying passengers; a riser 9 disposed upright on one edge in a depth direction of the tread 8; a step link roller shaft 10; a pair of step link rollers 11 that are rotatable around the step link roller shaft 10; a trailing roller shaft 12; and a pair of trailing rollers 13 that are rotatable around the trailing roller shaft 12.
  • the step link rollers 11 roll along the main tracks 5.
  • the trailing rollers 13 roll along the trailing tracks 6.
  • the step link roller shafts 10 of mutually-adjacent steps 2 are linked to each other by a pair of linking mechanisms (folding links) 14.
  • Each of the linking mechanisms 14 has first to fifth links 15 to 19.
  • a first end portion of the first link 15 is linked pivotably to the step link roller shaft 10.
  • a second end portion of the first link 15 is linked pivotably to an intermediate portion of the third link 17 by means of a shaft 20.
  • a first end portion of the second link 16 is linked pivotably to the step link roller shaft 10 of the adjacent step 2.
  • a second end portion of the second link 16 is linked pivotably by means of the shaft 20 to the intermediate portion of the third link 17.
  • a first end portion of the fourth link 18 is connected pivotably to an intermediate portion of the first link 15.
  • a first end portion of the fifth link 19 is connected pivotably to an intermediate portion of the second link 16.
  • Second end portions of the fourth and fifth links 18 and 19 are linked to a first end portion of the third link 17 by means of a sliding shaft 21.
  • a guiding groove 17a for guiding sliding of the sliding shaft 21 in the longitudinal direction of the third link 17 is disposed on the first end portion of the third link 17.
  • a rotatable auxiliary roller 22 is disposed on a second end portion of the third link 17. The auxiliary roller 22 is guided by the auxiliary tracks 7.
  • a pitch between the step link roller shafts 10, and thus a relative pitch between adjacent steps 2 is changed by the auxiliary rollers 22 being guided by the auxiliary tracks 7 to change the shape of the linking mechanisms 14 so as to fold and unfold.
  • tracks of the auxiliary tracks 7 are designed such that the relative pitch between adjacent steps 2 changes.
  • the speed of the steps 2 is changed by changing the pitch between the step link roller shafts 10 of adjacent steps 2.
  • the pitch between the step link roller shafts 10 is minimized and the steps 2 move at low speed.
  • the pitch between the step link roller shafts 10 is maximized and the steps 2 move at high speed.
  • the pitch between the step link roller shafts 10 changes and the steps 2 accelerate or decelerate.
  • the first, second, fourth, and fifth links 15, 16, 18, and 19 constitute a four-link "pantograph" linking mechanism, enabling an angle formed by the first and second links 15 and 16 to be enlarged and reduced with the third link 17 as an axis of symmetry.
  • the pitch between the step link roller shafts 10 linked by the first and second links 15 and 16 can be changed.
  • the pitch between the step link roller shafts 10 of adjacent steps 2 is minimized. From this state, when the distance between the main tracks 5 and the auxiliary tracks 7 is reduced, the linking mechanisms 14 operate in a similar manner to the operation of the frame of an umbrella as the umbrella is being opened out, increasing the pitch between the step link roller shafts 10 of the adjacent steps 2.
  • a traveling speed of the moving handrails 26 is constant over an entire region, such as being set so as to be equal to a traveling speed of the steps 2 in the intermediate inclined portion C, for example. Because of this, differences in amount of movement arise between the moving handrails 26 and the steps 2 when moving from the intermediate inclined portion C to the landing portions A and E, or vice versa, making the moving handrails 26 difficult to hold onto.
  • the present invention aims to solve the above problems and an object of the present invention is to provide a high-speed inclined portion escalator capable of suppressing a difference between a traveling speed of a moving handrail and a traveling speed of a step in order to make the moving handrail easy to hold onto even when the step changes speed.
