Example Embodiment

[0015] Below, will refer to Figure 1 to Figure 5 The escalator shown is used to describe an embodiment of the passenger transport device of the present invention.

[0016] The escalator 1 of the present invention is constructed as follows. That is, as Figure 4 As shown, a main frame 4 is installed between the upper ground 2 and the lower ground 3 that are vertically separated from each other. In the main frame 4, a plurality of steps 5 that move in the longitudinal direction of the main frame are guided. The front wheels 6 are supported in both sides in the width direction of the upper step side of the step 5, and the rear wheels 7 are supported in both sides in the width direction of the lower step side, and the interval between the rear wheels is longer than the interval between the front wheels 6. small. Such as figure 1 As shown, the front wheel 6 and the rear wheel 7 are rotatably supported on the step 5 through the axles 8 and 9 respectively, and the two axles 8 and 9 pro...

Abstract

A passenger conveying apparatus capable of reducing a step turning space, thereby reducing an installation space, and also enabling a step turning operation between the forward and rearward movements of the step to be performed smoothly, the passenger conveying The device comprises: a plurality of cyclically moving steps (5), wherein in the forward movement the pedals face upwards and in the return movement the pedals face downwards; 5) Circularly connected to each other; and a drive sprocket (13) and a drive sprocket (14) that circulate the step chain (12) around the turning portion between the forward path and the return path , wherein the step (5) is connected with the step chain (12) through the crank mechanism (8, 24, 25).

Description

technical field [0001] The present invention relates to passenger conveyances such as escalators, moving walkways, and more particularly to such passenger conveyances in which steps or treads pass through a diversion between a forward path and a return path Move and cycle through a 180-degree turn so that the treadplate goes up in the forward path and down in the return path. Background technique [0002] In a conventional passenger conveyance device such as an escalator, such as disclosed in Japanese Patent Application Laid-Open No. 1-55195, the step treads are movable and circulated, with the treads facing upwards at the forward path side, and the step treads at the return portion Turn 180 degrees so that the pedal faces down on the return path side. [0003] In the escalator having the above structure, the turning space of the steps is not taken into consideration, and therefore, the turning space of the steps is unnecessarily large. Thus, the turning space of the steps...
