席における手摺装置に関する。[Detailed description of the invention] Industrial application field The present invention is a method for extending the seats in a theater or gymnasium, etc., when it is desired to temporarily construct the seats, configuring the seats in a stair-like shape, and contracting the seats when not in use. The present invention relates to a handrail device for an extendable and retractable bleacher seat that can be stored in a corner of a room.

おいて公知である。Conventional technology and problems Conventionally, in theaters, gymnasiums, etc., when it is desired to temporarily install bleachers, the bleachers are extended to form a staircase-like structure, and when not in use, the bleachers are retracted and stored in a corner of the room. A handrail device for movable and extendable bleachers is known, for example, from Japanese Utility Model Application Publication No. 58-166745.

不揃いとなつて、体裁を著しく損うなどの欠陥を
有する。 However, according to the conventional structure, between the upper ends of the front and rear columns, which are erected at the front and rear end positions of the movable platform of each stage, respectively, in a forward tilted state and with the rear part deviated outward,
Since the front part is equipped with a handrail that is bent in an L-shape or a handrail that extends in a straight line, in the former case, there is not only a risk that objects may be caught while walking due to the presence of the L-shaped bent part. If the height of the handrail, which is set according to the average height of an adult, corresponds to the height of a child, there is a risk that the child's face or neck may get caught in the L-shaped bent part. Although this does not pose the above-mentioned dangers, when the bleachers are retracted, the rear column is largely deviated outward from the front column so that the handrail at the front position does not come into contact with the front column at the rear position, or The handrail position of the front stage must be shifted outward in sequence from that of the rear stage, and as a result, the rear column may be far away from the side edge of the movable platform, or the handrail position of the front stage position and the last stage position may be different. They have defects such as a large difference in outward direction, which requires a large amount of space when retracted, or the position of the handrails when extended is uneven, resulting in a significant loss of appearance.
