Description

  The present invention relates to a handrail guide adjusting device.

  Conventionally, escalators have been installed in commercial facilities. The escalator is provided with a handrail guide for guiding an endless moving handrail. Further, a driving roller for driving the moving handrail is provided near the end of the handrail guide. Depending on the relationship between the positions of the handrail guide and the moving handrail, the inner side surface of the moving handrail may come into contact with one side in the width direction of the handrail guide.

  If the escalator is used as it is, the handrail guide is scraped in the width direction by sliding between the inner side surface of the moving handrail and one side of the handrail guide. When the handrail guide is shaved in the width direction, a portion of the endless moving handrail corresponding to the shaved handrail guide is displaced in the width direction as compared with other portions. As a result, the operation state of the escalator may deteriorate due to the contact between the side surface of the driving roller that drives the moving handrail and the inner side surface of the moving handrail.

  As a technique related to the present invention, for example, Patent Document 1 has a crank shape as a whole, and has one end side facing down, and the back side in the width direction of the handrail guide (inside the escalator, viewed from the operator). An escalator jig is disclosed that moves the handrail guide to the front side in the width direction by engaging with the part on the rear side) and applying an external force toward the front side of the part extending upward on the other end side. ing.
