The moving handrail guiding device is fixed at one end of the curved portion 3 and pulled by a tension such as a spring at the other end so as to contact the bottom of the groove of the guard rail 6 of the curved portion 3 There is. A clip guide 5 made of resin excellent in slidability is fitted to the opening side end portion of the guard rail 6, and the moving handrail 1 circulates in sliding contact with the clip guide 5.

  FIG. 4 shows an exploded view of the moving handrail guiding device in the first embodiment of the present invention, and FIG. 5 shows a cross sectional view of the moving handrail guiding device along the line V-V shown in FIG. 3 in the first embodiment of the present invention. . The chain of the moving handrail guiding apparatus according to the first embodiment of the present invention includes a first chain piece 7 having a roller shaft 10 for holding a roller 9 and a second chain piece having a roller shaft 10 for holding a roller 9 as well. 8 are alternately fitted to form a plurality of first chain pieces 7 and second chain pieces 8 as one set. The traveling handrail 1 can smoothly circulate in the curved portion 3 by traveling on the roller 9.

  Each chain piece supports a plurality of rollers aligned side by side. Further, each of the chain pieces is provided with a link shaft and a link shaft hole. The first chain piece 7 and the second chain piece 8 are fitted together by inserting the respective link shafts 11 into the other link shaft holes 12. A projecting shape is provided at the tip of the link shaft 11 with respect to the outer diameter direction so that the link shaft 11 does not easily come off after the link shaft 11 and the link shaft hole 12 are fitted. It protrudes from the shaft hole 12.

  The first chain piece 7 includes a piece body 7a and roller shafts 10 extending in the left and right direction from both left and right sides of the piece body 7a. The second chain piece 8 includes a piece body 8a and roller shafts 10 extending in the left and right direction from both left and right sides of the piece body 8a.

  The roller shafts 10 extend from the piece main body in the left-right direction (a direction perpendicular to the traveling direction of the movable handrail 1, ie, in the direction of the balustrade with respect to the pair of left and right balustrades 2). The projection length of the roller shaft 10 from the piece main body is different in the left-right direction. For example, when referring to the paper surface of FIG. 4, the protrusion length on the right side of the paper surface of the roller shaft 10 of the first chain piece 7 is longer than the protrusion length on the left side of the paper surface of the roller shaft 10 of the first chain piece 7 Conversely, the projection length of the second chain piece 8 on the right side of the drawing is shorter than the projection length of the roller shaft 10 of the second chain piece 8 on the left of the drawing.

That is, in the arrangement mode of the rollers 9 of the moving handrail guiding device in the first embodiment of the present invention, the left and right biases are alternately switched with respect to the circulation direction of the moving handrail 1. More specifically, in the first embodiment, one roller 9 is disposed on the left and right sides of the piece main body, and two rollers 9 are disposed on the left and right sides. The second mode in which two rollers 9 are disposed and one roller 9 is disposed on the other is arranged alternately in the traveling direction of the moving handrail 1.

  Regarding the comparison of the end face position of the outermost roller on the same side in the left-right direction, the end face position 9a of the roller supported by the first chain piece 7 and the movement of the moving handrail 1 relative to the first chain piece 7 The end surface position 9b of the roller supported by the second chain piece 8 adjacent in the direction is shifted in the left-right direction.

  The roller 9 is press-fitted to the roller shaft 10, and when stacking the rollers 9, a washer 13 is inserted between the roller 9 and the roller 9 in order to prevent grease leakage due to contact between the rollers 9. .

  According to the first embodiment configured as described above, the following excellent advantages are obtained. In the moving handrail guiding device in the first embodiment, since the pin and the link plate are integrated, assembly of the chain is achieved by connecting each link shaft 11 of the first chain piece 7 and the second chain piece 8 to the other link shaft Since the process is completed by inserting and fitting in the hole 12, the assembly can be facilitated.

  Further, in the conventional moving handrail guiding device, depending on the position of the link plate provided on both sides of the roller, the pin may be slightly inclined within the allowable range, in which case the roller is slightly inclined and one of the moving handrails is inclined. There is also a problem in that wear of the canvas on the inner surface of the moving handrail is promoted because the end faces are in strong contact. In addition, the surface pressure of the roller against the moving handrail tends to be maximum at the end face of the roller, and the trajectories of the roller end face at the same position of the chain adjacent to the front and back with respect to the circulating direction of the moving handrail are colinear. There is also a problem that the peak position of the surface pressure of the inner surface of the moving handrail against the canvas by the roller end face is also overlapped, which accelerates the abrasion of the canvas.

  On the other hand, in the first embodiment, the trajectory of the inner surface of the moving handrail 1 on the end face of the roller 9 with respect to the canvas is not on the same straight line but on different straight lines for the first chain piece 7 and the second chain piece 8. Can be distributed as The surface pressure of the roller 9 on the moving handrail 1 tends to be maximum at the end surface of the roller 9, and the locus of the inner surface of the moving handrail 1 on the end surface of the roller 9 to the canvas (peak position of the surface pressure on the canvas of the moving handrail 1) is The peak position of the surface pressure against the canvas on the inner surface of the moving handrail 1 by the end face of the roller 9 is also dispersed by the chain piece 7 and the second chain piece 8 of the first chain piece 7 and the second chain piece 8 It is possible to

  Furthermore, since the inclination of the roller shaft 10 can be regulated at the stage of component manufacture, the wear of the canvas on the inner surface of the moving handrail 1 is prevented by the roller 9 being inclined and one end face strongly contacting the moving handrail 1 Thus, the useful life of the moving handrail 1 can be extended.
