Abstract

PURPOSE:To facilitate the shift and installation of a panel by installing and introducing groove and an introducing rod for accommodating a panel on the front stage, on the side panel in each stage and allowing the side panel to be superposed in accomodation and to be adjusted to an equal level in pulling- out. CONSTITUTION:A bracket 33 having an introducing groove 14 and an introducing rod 15 for accomodating a front stage panel is installed on the side panels 12A, 12B, 12C,... which are divided in each stage which constitutes a staircase- shaped spectator seat and slide on a rail. When the side panel 12 is accomodated, it can be accomodated in a superposed state by pushing in the panel. Further, when the panel is pulled out, the panel is adjusted to an equal level form. After the panel 12 is pulled out, a shiftable floor is laid on the panel, and the row of spectator seats are formed. Accordingly, the istallation of the spectator seat can be carried out efficiently.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding type side panel for a telescopic staircase seat which is a moving seat used for effective use of space such as a multipurpose hall.

[0002]

2. Description of the Related Art As shown in FIG. 18, a side panel of a conventional telescopic staircase has movable carriages 2A, 2B each having a supporting leg 5 having a stepwise difference in width and height.
2C, 2D (footrest 4 with traveling wheels 4a) and a multi-tiered row of spectators 1 composed of a deck 3 supported by a support beam 6 mounted above a supporting leg 5 on each of the movable carriages 2A, 2B, 2C, 2D.
A, 1B, 1C, 1D (chairs not shown in the figure) are arranged from the front in the order of low height and narrow frontage width, and when used, they are sequentially moved forward from the lowest row of bleachers. As a result, it extends in a staircase overall, and when not in use, it moves backward from the lowest front row of spectator seats 1A to the highest fixed row of spectator seats, thereby retreating to the lower deck 3 of each rear row. In the retractable staircase-shaped bleachers provided so as to be shortened to a vertical shelf shape as a whole, the last row of the lower deck 3 of the bleacher rows 1A, 1B, 1C, and 1D above each row is moved. At the left and right ends nearer to the outside of the trolley 2D, extend further rearward from the penetrating member 7 at the rear of the deck, and sequentially shift outwardly from the front stage to the rear stage for side panel mounting Fixing the support cake 8 to the penetrating material 7, By fixing the support grates 8 of the respective stages to the outside of the rearward extending portion from the penetrating member 7 through the mounting frames, respectively, the spaces are vertically separated from each other without interfering with the inner surface of each of the rear stages. When the bleachers rows 1A, 1B, 1C, 1D of the respective tiers are extended in a stepwise manner, the lower left and right parts of the deck 3 of each tier of the bleachers 1B, 1C, 1D are closed. Some have a side plate 9.
In the figure, reference numeral 10 indicates a bracket. (Actual public 63-2
