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.
  • FIG. 6 is a schematic side elevation showing steps of a conventional normal escalator.
  • steps 1 have: a tread 2 for carrying passengers; and a riser 3 disposed on an edge on a downstairs side of the tread 2.
  • Figure 7 is a cross section showing a portion VII of Figure 6 enlarged.
  • a plurality of tread cleats 2a extending in a direction of travel are disposed on a surface 2c of the tread 2.
  • a plurality of riser cleats 3a are disposed on a surface of the riser 3.
  • a plurality of pectinate protruding portions 2b are disposed on an edge portion (a demarcation comb) on an opposite side of the tread 2 from the riser 3 for insertion into the riser cleats 3a of an adjacent step.
  • the protruding portions 2b are formed continuously on end portions of the tread cleats 2a.
  • 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 of f , 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.
  • FIG 8 is a schematic side elevation showing steps of a conventional high-speed inclined portion escalator.
  • steps 4 have: a tread 5 for carrying passengers; and a riser 6 disposed on an edge on a downstairs side of the tread 5.
  • a pitch between adjacent step 4 or more precisely, a pitch between step link roller shafts (not shown) mounted to the steps 4 to support step link rollers disposed to bear the steps 4 is changed.
  • the pitch between the steps 4 is reduced in the upper and lower landing portions, and the pitch between the steps 4 is increased in the intermediate inclined portion.
  • a surface of the riser 6 forms an obtuse angle ⁇ relative to the tread of the step 4 adjacent on a lower side in the intermediate inclined portion. In other words, the riser 6 protrudes outward toward the step 4 adjacent on the downstairs side.
  • Figure 9 is a cross section showing a portion IX of Figure 8 enlarged.
  • a plurality of tread cleats 5a extending in the direction of travel are disposed on a surface of the tread 5.
  • a plurality of riser cleats 6a are disposed on a surface of the riser 6.
  • a plurality of pectinate protruding portions 5b are disposed on an edge portion on an opposite side of the tread 5 from the riser 6 for insertion into the riser cleats 6a of an adjacent step.
  • 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 enabling protruding portions on an edge portion of a tread to intermesh sufficiently with riser cleats even if a riser protrudes outward toward a step adjacent on a downstairs side.
  • a high-speed inclined portion escalator including: a cyclic path including an upper landing portion, a lower landing portion, and an intermediate inclined portion positioned between the upper landing portion and the lower landing portion; and a plurality of steps linked endlessly and moved cyclically along the cyclic path, the steps having a tread for carrying passengers is disposed, and a riser disposed on an edge of the tread, wherein a traveling speed of the steps in the intermediate inclined portion is set so as to be faster than a traveling speed of the steps in the upper landing portion and the lower landing portion, the riser protrudes outward toward an adjacent step on a downstairs side in the intermediate inclined portion so as to form an obtuse angle relative to the tread of the adjacent step, a plurality of riser cleats are disposed on a surface of the riser, a plurality of protruding portions inserted into the riser cleats are disposed on an edge portion of the tread, and
  • Figure 1 is a schematic side elevation showing a high-speed inclined portion escalator according to Embodiment 1 of the present invention.
  • a plurality of steps 12 linked endlessly are disposed on a main frame 11.
  • the steps 12 are driven by a drive unit (a step driving means) 13, and are moved cyclically.
  • a cyclic path for the steps 12 has: a forward section, a return section, an upper inversion portion, and a lower inversion portion.
  • the forward section of the cyclic path includes: 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.
  • the steps 12 have: a tread 14 for carrying passengers; and a straight riser 15 formed on one edge in a depth direction of the tread 14. Adjacent steps 12 are linked to each other by linking mechanisms 16. A pitch between the adjacent step 12 is changed by changing the shape of the linking mechanisms 16.
  • a speed of the steps 12 is changed by changing a pitch between step link roller shafts (not shown) disposed on adjacent steps 12. Specifically, the pitch between the step link roller shafts is minimized in the upper landing portion A and the lower landing portion E where the passengers get on and off, and the steps 12 move at low speed. The pitch between the step link roller shafts is maximized in the intermediate inclined portion C, and the steps 12 move at high speed. In addition, the pitch between the step link roller shafts changes in the upper curved portion B and the lower curved portion D, and the steps 12 accelerate or decelerate.
  • Figure 2 is a cross section showing part of Figure 1 enlarged.
  • a plurality of tread cleats 14b extending in a direction of travel are disposed on an upper surface the tread 2.
  • Aplurality of riser cleats 15a are disposed on a surface of the riser 15.
  • Apluralityof pectinate protruding portions 14c are disposed on an edge portion (a demarcation comb) on an opposite side of the tread 14 from the riser 15 for insertion into the riser cleats 15a of an adjacent step.
  • the protruding portions 14c are formed continuously on end portions of the tread cleats 14b.
  • a surface of the riser 15 forms an obtuse angle ⁇ relative to the tread 14a of the step 12 adjacent on the lower side in the intermediate inclined portion C.
  • the riser 15 protrudes outward toward the step 4 adjacent on the downstairs side in the intermediate inclined portion C.
  • End surfaces 14d of the protruding portions 14c (surfaces facing bottom surfaces 15b of the riser cleats 15a) form an acute angle ⁇ relative to the tread 14a.
  • the end surfaces 14d are parallel to an angle of inclination of the riser 15 and the bottom surfaces 15b, and are inserted completely inside the riser cleats 15a.
  • the entire end surface 14d is made to form an acute angle relative to the tread 14a, but as shown in Figure 3, for example, a portion 14e forming a right angle and a portion 14f forming an acute angle relative to the tread 14a may also be combined.
  • rounding may also be applied to a corner portion 14g between the tread 14a and the end surface 14d.
  • the entire end surface 14d may also be made into a gently curved surface.
  • the protruding portions 14c may be disposed so as to be integrated with a main body of the tread 14, or they may also be constructed using a different material from the main body.
