Description

  The present invention relates to a railing of a passenger conveyor that supports a moving handrail that is moved in synchronization with a step on, for example, an escalator or a moving sidewalk.

  Conventionally, for example, a passenger conveyor has been proposed in which a lower end portion of a balustrade panel that supports a moving handrail is covered with a deck cover in order to prevent a foreign object from falling into a truss or improve design. The gap between the balustrade panel and the deck cover is closed by packing along the deck cover. The packing is pressed against the balustrade panel in a state of being mounted on the deck cover (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 61-163282

  However, when the balustrade of a passenger conveyor is comprised by the several balustrade panels arranged in the longitudinal direction of the passenger conveyor, a level | step difference may arise in the boundary between each balustrade panel. In such a case, even if the side surface of the packing is pressed against the balustrade panel, it is difficult to bend the entire packing in accordance with the step, so a gap is generated between the packing and the balustrade panel at the step. . In addition, in order to close the gap at the stepped portion, for example, a method of bringing a plurality of divided gaskets into contact with each panel by cutting the packing at the stepped portion can be considered, but the designability is reduced or the number of parts is reduced. In addition to the increase, it takes time and labor to bring a plurality of packings into contact with each panel.

  The present invention has been made to solve the above-described problems, and can easily and more reliably close the gap between the deck cover and the balustrade body, and suppress the deterioration of the design. The purpose is to obtain a parapet for passenger conveyors.

  The balustrade of the passenger conveyor according to the present invention is arranged along the longitudinal direction of the passenger conveyor, and supports a moving balustrade body, a deck cover that covers a lower portion of the balustrade body, and between the side surface of the balustrade body and the deck cover. The packing has a packing that closes the gap, and the packing has a packing body that faces the side surface of the balustrade body, and a protruding piece that protrudes from the packing body to the balustrade body side and is thinner than the packing body. By being pressed against the side surface of the balustrade body, it is elastically deformed according to the shape of the side surface of the balustrade body.

  In the balustrade of the passenger conveyor according to the present invention, the thickness of the protruding piece is made thinner than the thickness of the packing body, and the protruding piece is pressed against the side surface of the balustrade body. The gap between the deck cover and the deck cover can be closed more reliably. Further, even when the packing is arranged at a position intersecting with the step generated on the side surface of the balustrade body, the gap can be closed by the common packing integrated, so that the operation of closing the gap is facilitated. In addition, it is possible to reduce the number of packing divisions, and to suppress a decrease in designability.
