Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an improvement in a handrail device for an extendable and movable staircase-like bleachers installed in a room with a wide floor surface such as a gymnasium.

Conventional technology and its problems Conventionally, in telescoping and movable tiered bleachers that are installed to enable multi-purpose use of indoor spaces with wide floors such as gymnasiums, in order to ensure the safety of spectators, each tier has been A structure in which handrail devices are provided at both ends of a movable bed is known, for example, from Japanese Patent Application Laid-Open No. 60-238576.

However, in the conventionally known device described above, the lower ends of the front and rear columns are attached to the respective side ends of the movable platform of each stage, so that the rear column is tilted forward, and the rear column is moved more than the front column. It is erected in a state that is offset outward from the edge of the floor platform, and the front and rear supports are provided at the upper ends of the front and rear columns of each tier. Since a side wall panel is attached to the wall, there are disadvantages as described below.

In other words, the relationship between the front and rear columns installed on each movable floorboard is vertical when viewed from the front, and the front columns are shifted inward and the rear columns are shifted outward, and the side wall panels are placed between the front and rear columns. Therefore, in order to prevent the side wall panels in the adjacent front and rear stages from interfering with each other, as shown in the above-mentioned known example, the lower edge of each side wall panel should be aligned with the side wall panel two stages before. It must be installed so that it is higher than the upper edge and so that adjacent comrades are alternately offset to the inside and outside of the support. A space will be created between the handrails, which will not only seriously spoil the appearance, but also cause a sense of uneasiness for users going up and down the bleachers. There is a risk that objects may fall from the handrail device and cause injury to people walking below.

OBJECTS, EMBODIMENTS AND OPERATIONS OF THE INVENTION Therefore, the present invention aims to improve the deficiencies of the above-mentioned conventional products, and one embodiment thereof will be described below with reference to the drawings. (1) a. (1)b.

(1)c, (1)d, and (1)e are horizontally long flat movable floor stands that are sequentially arranged in a step-like manner in the front-rear direction. Bogie legs (2
)a, (2)b, (2)c, (2)d, (2)
e, so that it can be extended into a step-like shape as shown in FIG. 1, or shortened into a vertical shelf-like shape as shown in FIG. These bogie ammunition bodies (2) a to (2) e each have a plurality of small wheels (3) and are long in the front-rear direction (4).
) and a support leg (5) that stands upward from one end of this leg base (4), forming an L-shape, so that the leg bases (4) are staggered sequentially from the previous stage. The movable bed stands (1)a to (1)b are arranged to support the movable bed stands (1)a to (1)b, and each stage of the movable bed stands (1)a to (1)b is connected to each cart (2)a to (2)e. They are arranged so that they can advance from the previous stage to the next front, or be retracted to the bottom of each subsequent stage. In this way, a chair (7) is attached to each of the movable platforms (1)a to (1)e, which can be expanded and contracted in a stepwise manner, through the base (6) so that the chair (7) can be raised and lowered. When each movable platform (1)a to (1)e is extended, it is held upright by appropriate means so that the audience can sit on it, and when each movable platform (1)a to (1)e moves backward, It is designed to collapse forward into a flat state so that it can penetrate into the lower side of the rear movable bed together with the movable bed.

The sides of the telescopic and movable stepped bleachers constructed in this way become walking paths, and therefore each movable platform (1) a to (1)
) e is provided with a handrail frame (8) at the side end thereof.

This handrail frame (8) is constructed in the same way for each stage, so
What is provided on the frontmost movable platform (1)a will be described in detail.

This handrail frame (8) consists of front and rear supports (11), (12), and a handrail rod (13), and is located at the front position of the side end surface of the movable platform (1) a, with the lower part facing slightly inward. Slanted front strut (
11) so that its sloped part (11)' slopes forward.
The lower ends of the rear struts (12) are fixed at the rear so that the rear struts (12) are tilted outward from the vertical position, and between the upper ends of the front and rear struts (11) and (12), Handrail (
13) by fixing it to a crossing rack. Handrail (
13) is bent in an abbreviated shape, and the rear strut (12)
A straight line part (13) a extends forward from the upper end parallel to the edge of the moving platform (1) a, and a right-angled part extends from the front end of this straight part (13) a to the upper end of the front support (11). Bend line part (1
3) Consists of b.

The side wall panel (14), which forms an outwardly sloping surface formed by the rear support (12) of the handrail frame (8) configured in this way and the straight part (13) a of the handrail rod (13), It is installed between the pillars (11) and (12). The side wall plate (14) can be attached directly on the rear column (12) side using an angled attachment member (15), and on the front column (11) side, it can be attached to the front column (11) and the handrail. A plate-shaped support member (16) corresponding to a substantially triangular space when viewed from the front is formed by the front edge of the side wall panel (14), which forms a surface formed by the bent line portion (13)b of the rod (13).
) is attached indirectly.

An angled bottom plate (17) is then installed between the lower edge of said side wall panel (14) and the moving platform so as to close the gap between them.

In this way, the handrail frame (8) to which the side wall panel (14) is attached is similarly provided on each of the other movable floor stands (1)b to (1)e.

In addition, in order to close the gap between the lower edge of the side wall panel (14) and the movable floor, the bottom plate (17) is inserted between them.
6.7 shows the case where the
The side wall panel (14) is extended downward to form an extension (1
The lower edge of 8) is fixed to the end surface of the movable platform side with a set screw (19), etc. In this case, the lower edge of the mounting member (
15) is used with its orientation reversed.

Therefore, when each movable platform (1) a to (1) e is moved backward and shortened, the front struts (11) overlap in the front-rear direction, and the rear struts (12) overlap in the lateral direction. Since they overlap, the straight part (13)a of the handrail rod (13) and the rear post (1
2) and a side wall panel (
14) 2. In each adjacent movable bed, the movable bed stands are moved sequentially from the previous one to the bottom of the latter one without interfering with each other, and as shown in FIG. 2, are shortened into a vertical shelf shape, and The handrail frame (8) comes to fit under each subsequent stage.

In addition, in the above embodiment, the handrail frame (8) is connected to the front and rear supports (1
1) and (12) are made to have the same apparent height, and the handrail rod (13) is suspended horizontally, but the rear support (12) is made higher and the handrail rod (13) is tilted downward. In addition, when installing the side wall panel (14), the lower surface of the straight part (13) a of the handrail rod (13) and the rear support (1
After providing a slit along the front surface of each panel 2) and inserting the upper and rear edges of the side wall panel (14) into the slit,
It may be attached by means of a support member (16).

Effects of the Invention As described above, according to the present invention, since no space is created between the side wall panel and the side end surface of the movable bed, the appearance in the extended state is very good. Therefore, it is possible to provide a handrail device for a spectator seat that is highly safe.
