Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to a curved passenger conveyor having a conveyance path which is shaped at least as part of a ring in a horizontal projection plane.

A curved passenger conveyor has an annular main frame in a horizontal projection plane, an outgoing path is formed on the top side of the main frame, a reversing part is formed at the end of the main frame, and a return path is formed near the bottom of the main frame. A conveyance path is configured.

Further, there is provided a step board having a fan-shaped plane and disposed continuously on the conveyance path with a large number of fan-shaped linear edges facing each other. These footboards are connected to each other by an outer chain on the outside of the ring of the conveyor path, and an inner chain on the inside thereof, and the outer and inner chains are driven by a drive device provided on the main frame, so that they are circulated through the conveyance path. Since the total length of the outer chain is longer than the total length of the inner chain, the moving treadle performs a reversal action at the reversal portion of the conveyance path along a conical surface having an apex near the center of the conveyance path ring. As a result, the treadle reversing mechanism becomes complicated, requires highly precise machining, and is expensive.

The present invention aims to solve the above-mentioned drawbacks and to provide a curved passenger conveyor that is simply constructed and can smoothly reverse the treadle.

An embodiment of the present invention will be described above with reference to FIGS. 1 to 8.

b) is not provided, the wave-shaped refraction of the inner shaft (7) is extended, and the inner steel +11 is reversed through a reversal path of the same length as the outer shaft (8) through the reversal mechanism (a). ) is flipped along the cylindrical surface. Therefore, the reversing mechanism (one of which constitutes a reversing path formed on the cylindrical surface) can be easily manufactured, and the tread plate (6) can be smoothly reversed. Also, the reversing operation of the tread plate (6) can be easily manufactured. sometimes tread (6)
For the engaging part (6C) of the engaging element (6b) provided in
Since the shaft (7) engaged with this retaining portion (6C) is relatively displaced, the footboard (6) passes through an inversion path consisting of a cylindrical surface. Further, after passing through the reversing section (5C), the second type roller 02 is introduced into the second inner rail (14b) by the introduction section (14c), bending the inner steel On, and when entering the reversing section (5C) into the trench, the second type roller 02 02 moves to a reversing operation via the introduction part (14c) and extends the waveform bending of the inner steel (11).Since the tread plate (6), outer and inner steel (8) 01, etc. are provided in this way, the drive device ( 17) When energized, the outer and inner steel!8
Through the drive of 1 Ql, the treadle (6) can be smoothly circulated by a simple device. Furthermore, in this embodiment, since the treadle (6) is provided with the Zyd roller (1119), the movement resistance of the treadle (6) is reduced, and the power of the drive device (1η) can be saved.

Note that even if the treads (6) in FIGS. 1 to 8 consist of steps that form a step between adjacent steps, that is, in the case of a curved escalator provided with steps, the first
It is clear that the same effect as the embodiment shown in FIG. 8 can be obtained.

As explained above, the present invention connects both sides of the tread in the width direction, which are arranged in a conveying path that forms at least a part of a ring in a horizontal projection plane, by an outer silver chain and an inner chain, and conveys an inner steel. It is bent into a waveform on the outbound and return routes to absorb the total distance difference between the outside and inside of the conveyance path ring.
In the reversing part, the wave-shaped refraction of the inner steel is extended to reverse the reversal path of the same length as the outer steel, so that the axis of the tread plate reverses the path along the cylindrical surface. As a result, the treadle can be reversed using a simple reversing mechanism, and a curved passenger conveyor that is inexpensive and can smoothly circulate the treadle can be realized.
