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).

きく後退させる必要がある。Problems to be Solved by the Invention By the way, according to the handrail device proposed by the applicant mentioned above, the lower end of the front support is attached to the side end surface of the movable bed so that the front support is tilted forward. In order to prevent gaps between the front and rear handrail devices when the bleachers are moved forward and extended,
It is necessary that the rear part of the front handrail device and the front part of the rear handrail device overlap in the lateral direction, and for this purpose, the mounting position of the rear support that constitutes the handrail device needs to be moved back significantly.
従つてこのように構成するときは、各移動床台

る。Means for Solving the Problem Therefore, the present application is configured so that the above-mentioned handrail device can be attached without increasing the front and rear width dimensions of the movable bed. The lower ends of the front strut are attached so as to be inclined forward and the rear struts are inclined outward, and between the upper ends of the front and rear struts, a An L-shaped handrail rod extending parallel to the side edge of the movable platform and bent inward, the tip of which is connected to the upper end of the front column, is horizontally mounted, and further connected to 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 telescoping staged bleachers with a handrail device configured to close the gaps between the sides and the side end surfaces with cover plates, the support bracket for attaching the lower end of the rear column is attached to the riser part of the movable platform. It is characterized by being attached to the rear side.
作 用
しかして、使用に際し、各移動床台を後退移動
して収縮した場合、前支柱同志は、その前後方向
で重なり合い、また後支柱同志は側面方向で重な

るので、観覧席全体の重量を著しく軽減する。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. Furthermore, since the rear column is attached to the support metal fittings, the rear portion of the movable platform located between the left and right support metal fittings can be omitted, thereby significantly reducing the weight of the entire audience seat.

Reference numerals 1a, 1b, 1c, 1d, and 1e are movable floor platforms in which riser portions 3 are raised at the rear ends of oblong flat plate-shaped floor portions 2 that are sequentially arranged in a step-like manner in the front-rear direction, and these are different from conventional ones. Similarly, the lengths in the left and right directions and the widths in the front and rear directions are all the same, and they are supported on truck legs 4a, 4b, 4c, 4d, and 4e of successively different heights, and are arranged in stages as shown in FIG. It can be expanded into a shape or contracted into a vertical shelf shape as shown in FIG. These trolley legs 4a to 4e
is L-shaped, consisting of a leg stand 6 that is long in the front and rear direction and each has a plurality of small wheels 5, and a support leg 7 that stands upward from one end of this leg stand 6. They are disposed so as to intervene sequentially from the front stage to the rear stage, and support movable floor platforms 1a to 1e, and each stage's movable platform 1a to 1e is integrated with each of the trolley legs 4a to 4e. In this way, the objects in the previous stage are advanced forward one after another, and the objects in each subsequent stage are retracted to the lower side. In this way, each movable platform 1a expands and contracts in a stepwise manner.
Chairs 9 are attached to the mounting bases 8 to 1e.
is attached so that it can be raised and lowered, and each movable floor platform 1
When the movable platforms a to 1e are extended, they are held upright by appropriate means so that the audience can take their seats, and when each movable platform 1a to 1e moves backward, they fall forward and become flat, becoming integrated with the movable platform. It is designed to be able to invade the bottom of the rear movable platform.

This support metal fitting 15 is attached to the rear side of the riser 3, and includes a vertically long fastening plate 16 that is fixed to the rear surface of the side end 3a of the riser 3 in an overlapping manner, and a horizontally extending rearward side from the upper edge of the fastening plate 16. The horizontal arm plate 18 extends rearward from the lower edge of the fastening plate 16 and has an overlapping piece 17 extending forward and overlapping with the upper surface of the side end 3a. An inclined plate 19 that is inclined so that the interval gradually decreases, and these fastening plates 16,
It is composed of a horizontal arm plate 18 and a vertical plate 20 that closes the outer surface of the inclined plate 19. Reference numeral 21 denotes edge fittings that cover the side surfaces of the movable floor platforms 1a to 1e, and a holding portion 22 having a U-shaped cross section in which the side surfaces of the riser portions 3 fit is provided at the rear, and the support fittings 15 are fastened. A plate 16 is fixed to the back surface of the holding part 22 and mounted on the movable floor tables 1a to 1e. Therefore, the lower end of the rear support 12 is attached to the outer surface of the vertical plate 20 of the support fitting 15 attached to the rear sides of the movable floor platforms 1a to 1e so as to project rearward.
