Description

  The present invention relates to passenger conveyors such as escalators and moving walkways, and more particularly to the configuration of support members for moving handrails (handrails).

  In general, a handrail guide that supports a moving handrail of a passenger conveyor is composed of a pair of left and right members in the width direction, and these upper surfaces are pressed by brackets, and the brackets are fixed to a guide frame by bolts. However, in the method of fixing the handrail guide as described above, it is necessary to fix the guide rail to the guide frame using a large number of bolts in the longitudinal direction of the moving handrail, and the mounting work is difficult. Further, as a result of the outer peripheral surface of the handrail guide being worn as it slides with the moving handrail, the handrail guide may need to be replaced, but the replacement work at that time is not easy. In addition, if the handrail guide wears, the moving handrail comes into contact with the metal bolts and brackets and damages the canvas on the inner peripheral surface of the moving handrail, adversely affects the driving state of the moving handrail, and accelerates the replacement time of the moving handrail. There is also a possibility.

  Therefore, conventionally, a concave portion is provided on a part of the outer peripheral side of the guide frame, and the handrail guide is formed of a pair of left and right guide pieces in the width direction, and the opposite sides of the guide pieces are extended to the inner peripheral side. As a structure for inserting these opposed portions into a common recess, it has been proposed that the handrail guide can be easily attached or replaced, and the safety and life of the moving handrail are improved (see, for example, Patent Document 1). ). The guide piece is made of resin.
