Abstract

A balustrade device for a passenger conveyor, wherein a plurality of balustrade posts are erected at intervals apart in a direction of travel of steps. A plurality of outer decks abut against each other at positions of the balustrade posts. Recesses, through which the balustrade posts are passed respectively, are provided in the mutually adjacent end portions of the outer decks. Gaps are provided respectively between edges of the recesses and the balustrade posts. A plurality of cover members which close the gaps are provided on top of the outer decks. Each of the cover members is fixed to the balustrade post via a retainer which is fixed to an end surface of the balustrade post on a side of the step.

First claim

The invention claimed is:

1. A balustrade device for a passenger conveyor, comprising:
a plurality of balustrade posts which are erected at intervals apart in a direction of travel of steps; and
a plurality of outer decks which are arranged in line with the direction of travel of the steps and abut against each other at positions of the balustrade posts, wherein
recesses, through which the balustrade posts are passed respectively, are provided in mutually adjacent end portions of the outer decks;
gaps are provided respectively between edges of the recesses and the balustrade posts;
a plurality of cover members which close the gaps are provided on top of the outer decks; and
each of the cover members is fixed to the balustrade post via a retainer that is fixed to an end surface of the balustrade post on a side of the step.

2. The balustrade device for a passenger conveyor according to claim 1 , wherein a rise-up prevention groove which prevents rising up of the cover member due to the cover member being inserted therein is provided on the end surface of at least one of the balustrade posts on a side opposite to the step.

3. The balustrade device for a passenger conveyor according to claim 2 , wherein
the retainer is fixed to the balustrade post by a retainer fixing screw; and
a slot for a retainer fixing screw through which the retainer fixing screw is passed is provided in the retainer.

4. The balustrade device for a passenger conveyor according to claim 3 , wherein
the cover member includes a cover main body which is superposed on the outer deck and closes the gap, and a cover fixing section which projects downwards from an end portion of the cover main body on a side of the step; and
the cover fixing section is superposed on the retainer and is fixed to the retainer via a cover fastener.

5. The balustrade device for a passenger conveyor according to claim 1 , wherein
the retainer is fixed to the balustrade post by a retainer fixing screw; and
a slot for a retainer fixing screw through which the retainer fixing screw is passed is provided in the retainer.

6. The balustrade device for a passenger conveyor according to claim 5 , wherein
the cover member includes a cover main body which is superposed on the outer deck and closes the gap, and a cover fixing section which projects downwards from an end portion of the cover main body on a side of the step; and
the cover fixing section is superposed on the retainer and is fixed to the retainer via a cover fastener.
