The outbound section of the circulation road has an upper landing section (upper horizontal section) 22a, an upper curved section 22b, an intermediate inclined section (fixed inclined section) 22c, a lower curved section, and a lower landing section (lower horizontal section). department).

The step 21 has: a step main body 25, a driving roller shaft 26 extending in the width direction of the step main body 25, a pair of driving rollers 27 freely rotatable around the driving roller shaft 26, and a follower extending in the width direction of the step main body 25. A roller shaft 28 and a pair of follower rollers 29 rotatably centered on the follower roller shaft 28 . The step main body 25 has a step 30 on which passengers are placed, and a riser 31 erected at one end portion of the lower step of the step 30 . The riser 31 has a shape protruding to the lower side at the middle inclined portion. The drive roller 27 rotates along the drive rail 22 . The follower roller 29 rotates along the follower guide rail 23 .

The driving roller shafts 26 of the mutually adjacent steps 21 are connected to each other by a pair of link mechanisms (zigzag links) 32 on both sides of the step main body 25 . Each link mechanism 32 has first to fifth links 33 to 37 .

One end portion of the first link 33 is rotatably coupled to the drive roller shaft 26 . The other end portion of the first link 33 is rotatably coupled to an intermediate portion of the third link 35 via a shaft 38 . One end portion of the second link 34 is rotatably coupled to the drive roller shaft 26 of the adjacent step 21 . The other end portion of the second link 34 is rotatably coupled to an intermediate portion of the third link 35 via a shaft 38 .

One end portion of the fourth link 36 is rotatably connected to the middle portion of the first link 33 . One end portion of the fifth link 37 is rotatably connected to the middle portion of the second link 34 . The other ends of the fourth and fifth links 36 and 37 are connected to one end of the third link 35 via the slide shaft 39 .

One end portion of the third link 35 is provided with a guide groove 35 a that guides the slide shaft 39 to slide in the longitudinal direction of the third link 35 . A freely rotatable auxiliary roller 40 is provided at the other end of the third link 35 . The auxiliary roller 40 is guided by the auxiliary guide rail 24 .

By guiding the auxiliary roller 40 by the auxiliary guide rail 24, the link mechanism 32 is flexed and deformed, and the distance between the driving roller shafts 26 of the adjacent steps 21, that is, the distance between the adjacent steps 21 is changed. In other words, the track of the auxiliary guide rail 24 is designed such that the intervals between adjacent steps 21 are changed.

Next, FIG. 2 is a front view showing the step 21 in FIG. 1 . Both end portions of the drive roller shaft 26 protrude from both end portions in the width direction of the step main body 25 . Drive rollers 27 are installed near both ends of the drive roller shaft 26 . The link mechanism 32 is connected to the drive roller shaft 26 between the step body 25 and the drive roller 27 . When the step 21 is viewed from the front, the follower roller 29 is arranged within the width range of the step main body 25 .

FIG. 3 is an explanatory view showing the position of the follower roller 29 with respect to the stepped main body 25 in FIG. 1 . When the pedal 30 is placed on the upper side in a horizontal state, and the step 21 is viewed from the side, the follower roller 29 is arranged in the overlapping region (the region indicated by the oblique lines in FIG. The lower end portion is in contact with the lower side of the straight line L1 parallel to the middle inclined portion 22c (opposite side to the step main body 25), and the lower side of the horizontal straight line L2 (opposite side to the step main body 25 ) in contact with the lower end portion of the riser 31. the area on the opposite side). In addition, the follower roller 29 is arrange|positioned in the area|region closer to the drive roller shaft 26 side than the straight line L3 which connects the upper end part and the lower end part of the riser 31. As shown in FIG.

Next, the operation will be described. The speed of the steps 21 is changed by changing the distance between the driving roller shafts 26 of the adjacent steps 21 . That is, in the upper landing portion 22a and the lower landing portion where passengers board and disembark, the interval between the driving roller shafts 26 of the adjacent steps 21 is minimized, and the steps 21 move at a low speed. In addition, in the intermediate inclined portion 22c, the distance between the driving roller shafts 26 of the adjacent steps 21 is maximized, and the steps 21 move at high speed. In addition, in the upper curved portion 22b and the lower curved portion, the distance between the driving roller shafts 26 is changed, and the step 21 is accelerated and decelerated.

The 1st, 2nd, 4th and 5th connecting rods 33, 34, 36, 37 constitute a so-called zoom-type 4-joint linkage mechanism, which can take the 3rd connecting rod 35 as the axis of symmetry, or increase or decrease The angle formed by the first and second links 33 and 34. Accordingly, the distance between the driving roller shafts 26 of the adjacent steps 21 connected to the first and second links 33 and 34 can be changed.

In the landing portion of FIG. 1 , the distance between the driving roller shafts 26 of adjacent steps 21 is minimized. If from this state, narrow the interval between driving guide rail 22 and auxiliary guide rail 24, then link mechanism 32 carries out the action identical with the action of the umbrella stand group when opening umbrella, makes the driving roller shaft 26 of adjacent step 21 The interval expands.

In the intermediate inclined portion 22c in FIG. 1, the distance between the driving rail 22 and the auxiliary rail 24 is the smallest, and the distance between the driving roller shafts 26 of the adjacent steps 21 is the largest. Therefore, in this region the velocity of the step 21 is at a maximum. In addition, in this state, the first and second links 33 and 34 are arranged approximately on a straight line.

In the high-speed escalator at the inclined portion as described above, since the follower roller 29 is arranged in an area where the area below the straight line L1 and the area below the line L2 overlap in FIG. A simple configuration such as not providing a notch portion can prevent the follow-up rail 23 from interfering with the riser 31 .

FIG. 4 is an explanatory view showing the positional relationship between the follower guide rail 23 and the riser 31 when the step 21 of FIG. 3 moves on the intermediate inclined portion of the circuit side section. That is, FIG. 4 shows a state where the step 21 in FIG. 3 is reversed. Therefore, in FIG. 4 , the follower roller 29 is arranged in an area above the straight line L1. Along with this, the follower guide rail 23 that guides the follower roller 29 is arranged above the step 21 with the same inclination as that of the middle inclined portion. Therefore, interference between the follower rail 23 and the riser 31 can be prevented even in the intermediate inclined portion of the circuit side section.

FIG. 5 is an explanatory view showing the positional relationship between the follower rail 23 and the riser 31 when the step 21 of FIG. 3 moves in the horizontal portion of the circuit side section. In this state, the follower roller 29 is arranged in an area above the straight line L2. Along with this, the following guide rail 23 guiding the follower roller 29 is horizontally arranged above the step 21 . Therefore, interference between the follower rail 23 and the riser 31 can be prevented even in the horizontal portion of the circuit side section.

Also, interference between the follower rail 23 and the riser 31 can be prevented in other parts of the circulation path. That is, interference between the follower rail 23 and the riser 31 can be prevented in the entire circulation path.

Furthermore, since the follower roller 29 is disposed within the width of the step main body 25 when the step 21 is viewed from the front, it is possible to prevent the overall width of the escalator from increasing.

Furthermore, when the step 21 is viewed from the side when the step 21 is viewed from the side with the pedal 30 in a horizontal state, the follower roller 29 is arranged on the driving roller shaft 26 side compared with the straight line L3 connecting the upper end and the lower end of the riser 31. Therefore, the distance between the driving roller shaft 26 and the follower roller shaft 28 becomes smaller, the radius of rotation when the step 21 reverses can be reduced, and the overall size can be reduced.
