That is, both sides of the steps (3) in the width direction are connected to each other by an inner chain (5) or an outer chain (6), and are connected to each other by a drive device (not shown).

The outer chain (5) is circulated through the conveyor path (2) via the outer chain (5) t6). Then, the drive wheel (
3b), the follower shaft (3C) is guided and rolls, and the conveyance path (
In 2), at least on the outgoing path (2a), the step (3) maintains a horizontal posture and moves in an inclined manner, and in the horizontal part (2d), it moves horizontally, and at least on the outgoing path (2a) and the horizontal part (2a) connected to the outgoing path (2a). Steps (3) adjacent to each other in 2d)
The cleats (3θ) (3f) engage and move.

Then, the step (3) has a reversing mechanism (
7) causes inversion operation.

At this time, the step (3) operates as described below.

That is, as shown in FIG. 1, R'1: Radius of the width center line of the inner chain (5) in the outward path (2a) and the horizontal part (2d) R'2: In the outward path (2a) and the horizontal part (2d) Radius R1 of the width center line of the outer chain (6): Conveying path (2) in the plane of the reversing part (2b); width center line and arc center R of the inner chain (5) corresponding to a circular arc

The inner chain (5) has a radius R'1
．． The outer chain (6) moves in a trajectory of radius R'2. Then, in the reversing part (2b), the conveyance path (2
) The inner edge of the arc leans toward the depth center line of the main frame (1), so the inner chain (5) moves along a trajectory with radius R1 smaller than radius R'1, and the outer chain (6) moves with radius R'1. '
2. Move locus 7 of R2 smaller than 2. By setting the ratio of the small chain wheel (7a) and the large chain wheel (7b) of the 1 reversing mechanism (7) as N: r2=R'1: R'2, the inner and outer chains (7a) (7
Is the moving speed ratio of b) R' 1 : R' 2 and the step (3) smoothly turns into a conical surface? The E=75 trajectory is reversed.

As a result, the main frame (1
)7 It is possible to obtain a one-circular escalator that can be downsized and easily installed in a small space.

Furthermore, the steps (3) are arranged at least on the outbound route (2a) and the outbound route (2a).
In the horizontal part (2d) connected to step 2a), the adjacent step (3
) between each other. The space hq shown in FIG. 8 forms a shadow and moves in mesh with the spacers 'J-) (3θX3f)'f. Then, by being pushed up by the following shaft (3C) or the guide rail (8) as shown in Fig. 8, the following shaft (3C) side of the step (3) rises and tilts, and the gap between the steps (3) expands to A or A+B. be done. Cleat (
(e
The G5 trajectory is reversed on the conical surface with the inner edge of the 21 arc approaching the center of the reversal part (2b).

Once this is done, the steps (3) provided can be easily reversed.

As explained above, the present invention has an internal chain on one side in the width direction of a step provided on a conveying path that is arc-shaped and inclined in a horizontal projection plane, and a chain on the other side in the width direction.
The conveyor path is connected by a sea bream chain and operated in circulation, and the inner chain is wrapped around the reversing part of the conveyor path, and the small chain wheel is wrapped around it, and the large chain wheel with the outer chain is wound around. is reversed by a trajectory along a conical surface. This allows the tube to be moved smoothly without having to turn the steps around, and the middle frame can be made smaller and can be easily installed in a small space. In addition, a guide rail 5 is provided between the horizontal part of the conveyance path and the inverted part to displace the following axis of the step in a direction away from the center line of the depth of the main frame. When moving from the horizontal part to the inverted part, the steps are displaced and tilted in a direction away from the edge of the follower shaft side or the center curve of the depth of the main frame!, thereby widening the distance between the steps by 2 and engaging the cleats with each other. Since the escalator is released, it is possible to realize a circular escalator that can be smoothly reversed in a small space even if the steps are provided with cleats on the risers.
