Description

  The present invention relates to passenger conveyors such as escalators and moving walkways, and more particularly to the structure of a guide device for the moving handrail.

  In general, passenger conveyors such as escalators and moving walkways are provided with handrails that have a transverse C-shaped cross section, are connected endlessly, and run around the balustrade in synchronization with the steps. As a means for guiding the movement of the handrail on the return side, conventionally, a roller for preventing the handrail from slackening, and an inner side of the handrail having a C-shaped cross section for preventing the meandering in the width direction. There has been disclosed one provided with a guide that is inserted into the housing (for example, see Patent Document 1).

JP 04-371485 (paragraph numbers 0011 to 0013, FIG. 2)

  In the conventional device described above, a guide is inserted inside the handrail, and the inner side surface of the handrail and the outer side surface of the guide slide to prevent meandering of the handrail. For this reason, it is necessary to fit a guide having a width dimension substantially the same as the width dimension inside the handrail to the inside of the handrail, and there is a problem that it takes a lot of labor and time for the installation work of the handrail.

  The present invention has been made from the actual situation in the above-described prior art, and an object thereof is to provide a passenger conveyor that can facilitate the installation work of the handrail.

  In order to achieve the above object, the present invention provides a frame body installed on a building structure, a step guided endlessly connected to the frame body, and the frame on both sides along the moving direction of the tread board. A balustrade erected on the body, a handrail driven by a handrail drive machine and running around the balustrade in synchronization with the steps, and a hand on the return side of the handrail for guiding the handrail The passenger conveyor provided with the rail return side guide means is characterized in that the hand rail return side guide means is in sliding contact with the bottom surface and the left and right side surfaces of the hand rail.

  In the present invention configured as described above, the guide that fits inside the handrail as in the prior art is provided by making the handrail return path guide means slidably contact with the bottom surface and the left and right side surfaces of the handrail. Therefore, it is possible to provide guidance while preventing the handrail from meandering when traveling on the return side. This eliminates the need for complicated work such as inserting the guide inside the handrail when the handrail is installed, so that the handrail can be installed easily.

  Further, according to the present invention, the handrail return-side guide means includes a roller slidably contacting the bottom surface of the handrail, and a disk-shaped guide attached to both sides of the roller and slidably contacting the left and right side surfaces of the handrail. It is characterized by becoming.

  In the present invention configured as described above, the bottom surface of the handrail traveling on the return path side is guided by rollers, and the left and right side surfaces are guided by disk-shaped guides attached to both sides of the roller. As described above, the handrail return-side guide means has an integrated structure such as a roller and guides attached to both sides of the roller, so that the installation work can be made easier and the production cost can be reduced. it can.

  ADVANTAGE OF THE INVENTION According to this invention, the installation operation | work of a handrail can be made easy and reduction of work labor and work time can be aimed at.

1 is an overall configuration diagram of a passenger conveyor to which the present invention is applied. It is a principal part enlarged view which follows II of FIG. 1 which shows one Example of this invention.

  Embodiments of a passenger conveyor according to the present invention will be described below with reference to the drawings.

  A passenger conveyor, for example, an escalator, as shown in FIG. 1, is a frame 1 installed in a building structure A or B, and boarding / alighting floors 2A and 2B provided at both longitudinal ends of the frame 1 The main sprocket 3A and the sub sprocket 3B arranged in the vicinity of the getting-on / off floors 2A, 2B, the step chain 4 and the step 5 that are connected endlessly between the getting-on / off floors 2A, 2B, and the step chain 4 are driven. Driven by a driving device 6, a balustrade 7 standing on the frame 1 on both sides along the moving direction (rotation direction) of the step and facing the left and right, and a handrail drive 8 provided inside the balustrade 7, A plurality of handrails 9 that run around the step 7 in synchronism with the step 5, and a handrail return side guide means 10 that is arranged along the frame 1 and that guides the handrail 9 on the return side of the handrail 9; It is provided.

  As shown in FIG. 2, the handrail return path guide means 10 is attached to the roller 10a slidably in contact with the bottom surface of the return path handrail 9K, and is attached to both sides of the roller 10a and slidably contacts the left and right side surfaces of the handrail 9K. It consists of disk-shaped guides 10b and 10c. The roller 10a is rotatably supported by the frame body 1 via the bracket 11.

  In this embodiment, the handrail 9 is driven by the handrail drive 8 and travels around the balustrade 7 in synchronization with the step 5. The handrail 9K traveling on the return path side is guided by the roller 10a on the bottom surface and guided by the disk-shaped guides 10b and 10c attached to both sides of the roller 10a without meandering. Run smoothly.

  According to the present embodiment, the installation work of the handrail can be facilitated, and the work labor and the work time can be reduced. Further, the handrail return-side guide means 10 is integrated with the roller 10a and the guides 10b and 10c attached to both sides of the roller 10a, thereby facilitating the installation work and reducing the manufacturing cost. Can be achieved.
