案ずみである。 By the way, the handrail device for the conventionally configured bleachers described above has a defect in that a space is created between the lower part of the handrail frame and the side end surface of the movable platform, allowing objects to fall.This defect has been improved. In order to do this, the applicant first attaches the lower ends of the front strut to the side end surfaces of the movable platform so that the front strut is tilted forward and the rear strut is tilted outward, and
between the upper ends of the front and rear struts, extending forward from the upper end of the rear strut parallel to the side edge of the movable platform;
An L-shaped handrail rod that is bent inward and whose tip is connected to the upper end of the front column is horizontally supported, and is further supported by the rear column and a long part extending forward of the handrail rod. A front surface formed by the front support and the short portion extending inwardly of the handrail lever, and a gap between the side surface and the side end surface of the movable platform are each covered by a cover plate. A special request was made for a handrail device for a stair-shaped bleachers that can be extended and retracted so that they can be folded up and closed.
No. 61-199967 (Unexamined Japanese Patent Publication No. 63-60372) and Patent Application No.
It was proposed in No. 61-199968 (Japanese Unexamined Patent Publication No. 63-60373).

寸法が高くなる。Problems to be solved by the invention By the way, according to the above-mentioned handrail device proposed by the applicant, the front columns of the handrail device provided on each movable bed platform overlap in the front and back direction, and the rear columns overlap each other in the side direction. Since the seats are retracted in a compressed manner by overlapping in the direction, in order to obtain the mechanical strength of the handrail frame, if a material with a large diameter is used, it is necessary to increase the outward inclination of the rear column. Alternatively, it is necessary to increase the height interval between the movable platforms, so in the former case, the width of the bleachers becomes wider, and in the latter case, the height increases in proportion to the number of stages of the movable platforms.

とするものである。Means for Solving the Problems In other words, in order to achieve the above object, the present application provides a structure on the side end surface of the movable platform so that the front column is inclined forward and the rear column is inclined outward. , their lower ends are respectively attached, and between the upper ends of the front and rear struts, there is a distal end extending forward from the upper end of the rear strut parallel to the side edge of the movable platform and bent inward. horizontally spans an L-shaped handrail rod connected to the upper end of the front column, and further includes the rear column;
a side surface formed by the long portion extending forward of the handrail rod, a front surface formed by the front support and a short portion extending inward of the handrail rod, and a side surface formed by the side surface and the movable platform. In a handrail device for a telescoping staircase-shaped bleacher seat configured to close the gap between the side end surface with a cover plate, the handrail frame is formed by bending a metal pipe to connect the front support and the short part of the handrail rod. by a first bent part, a short part and a long part of the handrail rod by a second bent part, a long part of the handrail rod and a rear column by a third bent part, and
It is characterized in that the rear strut is formed flat in the lateral direction.

く、各移動床台は前段のものから順次後段のもの
の下側に退入して、垂直棚状に収縮される。Function: When each movable platform is moved backward and retracted during use, the front columns overlap in the front and rear directions, and the rear columns overlap in the side direction, so the handrail devices may interfere with each other. Instead, each movable platform is retracted from the previous one to the bottom of the next one, and is contracted into a vertical shelf shape.

ける惧れがない。 In the present application, since the rear strut is formed to be flat in the lateral direction, in the contracted state,
The overlapping width of the rear struts in the handrail device in the lateral direction is reduced, thereby reducing the outward inclination of the rear struts and the height spacing between the movable platforms, and
Since the handrail frame is formed by bending and molding a metal pipe, its corners are rounded and there is no risk of catching pedestrians or objects.

1a, 1b, 1c, 1d, and 1e are horizontally long flat movable platforms that are sequentially arranged in a step-like manner in the front-rear direction, and like the conventional ones, these have a length in the left-right direction and a width in the front-rear direction. Truck legs 2a, 2b, 2c, 2d, 2e are all the same and have different heights in sequence.
It is supported above so that it can be expanded into a step-like shape as shown in FIG. 1, or contracted into a vertical shelf-like shape as shown in FIG. These trolley legs 2a to 2
e is an L-shaped leg stand 4 that is long in the front-rear direction and has a plurality of small wheels 3, and a supporting leg 5 that stands upward from one end of this leg stand 4. are arranged so that the one in the front stage intervenes in the inside of the one in the rear stage one after another, and supports the movable bed platforms 1a to 1e. They are designed to move forward in sequence starting from the previous stage, or to be retracted below the respective rear stages. In this way, each movable platform 1 expands and contracts in a stepwise manner.
Chairs 7 are attached to a to 1e via attachment bases 6 so that they can be raised and lowered, and when each movable floor platform 1a to 1e is extended, they are held upright by appropriate means so that the audience can sit. 1a to 1e
When it moves backward, it falls forward and becomes flat, so that it can penetrate into the lower side of the rear movable bed together with the movable bed.
