Problems solved by technology

[0006] However, the former of the above-mentioned prior art does not consider the situation when the width dimension needs to be further reduced, so in fact it is difficult to further reduce the dimension in the width direction.
[0007] Moreover, in the latter of the above-mentioned prior art, at the entrance and exit portion of the passenger conveyor, since the interval of the moving handrail is narrower than that of the railings that have been widened, the interval difference will correspondingly form a drastic ups and downs. Poor, so there is a problem that the back of the guide part that guides the moving armrest will collide with the carry-on luggage, causing the passenger to fall

Embodiment Construction

[0021] based on the following Figure 1 to Figure 6 The escalator shown is a description of a passenger conveyor as one of the embodiments of the present invention. In general, the escalator 1 is constructed on the basis of a main frame 4 installed across the upper floor 2 and the lower floor 3 of a building. Such as image 3 As shown, the main frame 4 is composed of a pair of left and right side frames 5A, 5B and the bottom plate 6 and beams 7 connecting the left and right side frames 5A, 5B, etc., and the side frames 5A, 5B are formed along the length of the escalator The upper string material 8A and the lower string material 8B extending in the same direction and the longitudinal member 9 connecting the upper string material 8A and the lower string material 8B are formed.

[0022] The upper horizontal part 10 used as the upper machine room is formed on the upper layer 2 side of the main frame 4 adopting the above structure, and the lower horizontal part 11 used as the low...

Abstract

A passenger conveyor that can be sufficiently reduced in the width dimension of a main frame of course and allows passengers to ride no with sufficient room despite the reduction in the width dimension of the main; eliminating the possibility of the baggage or the like hitting the railings when passengers get. To this end the passenger conveyor is so constructed that the teeth of main sprocket and a drive sprocket coaxial therewith having a treadboard chain entrained therearound overlaps a side frame; as seen in their vertical projective figures the side frame constituting the main frame; and that the inner surface spacing between the right and left railings is greater than that of the moving handrails and in the longitudinal terminal ends of the railings the inner surface spacing made greater gradually approaches the spacing of the moving handrails.

Description

technical field [0001] The invention relates to a passenger conveying device for an escalator, an electric passage, etc., in particular to a passenger conveying device suitable for being arranged in a narrow place. Background technique [0002] In order to reduce the width dimension of the passenger conveyor, a conventional method that has been disclosed is to adopt a structure in which a motor is arranged around a drive shaft driving a step to directly drive the drive shaft (for example, Japanese Patent Laid-Open No. Sho 56-108683 ), or It adopts a structure in which a step driving chain is directly driven between the going channels of the steps (for example, Japanese Patent Application Laid-Open No. 55-40185). [0003] In addition, for example, Japanese Patent Application Laid-Open No. 2001-139273 discloses a technology in which the distance between the left and right railings is set to be greater than that of the left and right moving handrails in order to avoid collision...
