Problems solved by technology

[0004] In the above-mentioned prior art, the pivotal support structure of the pedal rear wheel must be designed into a special shape, and if this technology is applied to the middle part of the frame length direction, since the pedal rear wheels on the going side and the return side are in the There is a problem that it is impossible to secure a beam installation space between the outbound side and the return side because it is repeated in the up and down direction
For this reason, there is a problem that the height dimension of the frame must be enlarged when setting the beam

Embodiment Construction

[0065] Hereinafter, a first embodiment of the passenger conveyor of the present invention will be described with reference to the escalator shown in FIGS. 1 and 2 .

[0066] The escalator 1 is mainly composed of a frame 4 spanning between an upper floor 2 and a lower floor 3 , a plurality of steps 5 circulating in the frame 4 , and along the steps 5 on both sides in the width direction of the frame 4 . A pair of left and right railings 6 erected in the walking direction and a moving handrail 7 that moves synchronously with the moving speed of the steps 5 under the guidance of the peripheral edge of the railings 6 constitute.

[0067] The frame 4 includes: an upper machine room area 4A in which an upper machine room 10 for setting a driving device 8 and a drive sprocket 9 etc. is formed at both end portions in the length direction; In the lower machine room area 4B of the lower machine room 12 of the illustrated step cleaning device, etc., an intermediate area 4C is formed betw...

Abstract

The invention provides a passenger transport device which can reduce high size of a middle part of a frame without designing a pedal structure including a wheel into specific structure. In middle parts (4C, 4D, 4E, 4c) along length direction of the frame (4), a down part of a beam (14) opposite to pedals (5b, 29b) in return path side forms concave parts (21, 22, 23), and one part of the pedal in backhaul side steps through the concave part. Stepped trace of the pedal in return path side closes to stepped trace of the pedal in go path according with the structure, thus, high size of the middlepart of the frame can be reduced without designing a pedal structure including a wheel into specific structure.

Description

technical field [0001] The present invention relates to an escalator in which a plurality of steps for conveying passengers can form a height difference in an inclined area and an electric channel such as an electric channel without a height difference between adjacent steps, especially relates to a passenger conveying device that can properly Passenger conveying equipment installed in stairs and passageways. Background technique [0002] In general, when passenger conveying equipment is installed in stairs, passages, etc., it is preferable to reduce the height dimension of the frame as much as possible in order to minimize the amount of excavation of steps, passages, etc. For this reason, for example, Japanese Patent Application Laid-Open No. 2001-10775 of Patent Document 1 discloses a passenger conveyor that changes the travel position of the rear wheels pivotally supported by the pedals on the outbound side and the return side, The rear wheels traveling on the outbound s...
