改良に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an improvement in a handrail device for telescoping and movable stair-shaped bleachers installed in a room with a wide floor such as a gymnasium.

従来の技術とその問題点 従来、体育館等の広い床面を有する室内を多目

た構成のものは、例えば特開昭60−238576号公報
において公知である。Conventional technology and its problems Conventionally, in telescoping and movable staircase-like bleachers installed to enable multi-purpose use of large indoor spaces 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 Laid-Open No. 60-238576.

ところが、上記した従来公知のものは、各段の

設け、さらに、各段の前後支柱間に側壁パネルを
張設して成るので、以下に述べるような不都合を
有する。 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 by supporting the front and rear at the upper ends of the front and rear columns of each tier, handrail rods are provided respectively, and furthermore, a handrail is provided between the front and rear columns of each tier. Since a side wall panel is attached to the wall, there are disadvantages as described below.

即ち各移動床台に立設した前後支柱の関係は、

利用者に不安感を与えると共に、手摺装置の下方
は、人間の歩行する場所となるので、手摺装置か
ら、物が落下して、その下方を歩行する者に傷害
を与えるという危険性を有する。 In other words, the relationship between the front and rear supports installed on each movable platform is as follows:
When viewed from the front, it is in a vertical state, with the front struts shifted inward and the rear struts shifted outward, and side wall panels will be stretched between the front and rear struts, so the side walls of the adjacent front and rear stages will be In order to configure the panels so that they do not interfere with each other, as shown in the above-mentioned known example, the lower edges of each panel should be at a higher position than the upper edge of the two previous side wall panels, and the adjacent It is necessary to install the side wall panels in the front and rear tiers so that they are offset alternately to the inside and outside of the support, and as a result, a space is created between the lower edge of the side wall panels in each tier and the floor of the movable platform. Not only does this seriously spoil the appearance, it also gives a sense of unease to users going up and down the bleachers, and since the area below the handrail is a place where people walk, objects may fall from the handrail and the area below it. There is a risk of injury to people walking on the road.

つている。OBJECTIVES, 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.
b, 1c, 1d, and 1e are horizontally long flat movable floor stands arranged in a stepwise manner in the front-rear direction, and like the conventional ones, these have the same length in the left-right direction and width in the front-rear direction. It is supported on cart legs 2a, 2b, 2c, 2d, and 2e of successively different heights, and extends in a step-like manner as shown in Fig. 1.
As shown in FIG. 2, it can be shortened into a vertical shelf shape. These trolley legs 2a to 2e are
It is L-shaped and consists of a leg stand 4 that is long in the front and back direction and has a plurality of small wheels 3 each, and a support leg 5 that stands upward from one end of this leg stand 4. The movable platforms 1a to 1b are arranged in a staggered manner to support the movable platforms 1a to 1b, and the movable platforms 1e to 1b of each stage are integrated with the respective trolley legs 2a to 2e to support the movable platforms 1a to 1b of the previous stage. It is designed to move forward one by one from one object to the next, or to retreat to the bottom of each subsequent object. In this way, a chair 7 is attached to each of the movable platforms 1a to 1e, which can be expanded and contracted in a stepwise manner, via an attachment base 6 so as to be able to rise and fall, and when each of the movable platforms 1a to 1e is extended, The spectators can be seated by being held upright by the means, and when each movable platform 1a to 1e moves backward, it falls forward and becomes a flat state, and is integrated with the movable platform under the rear movable platform. It has become possible for it to penetrate.

ら成る。 This handrail frame 8 is made up of front and rear supports 11, 12 and a handrail rod 13, and the front support 11, whose lower part is slightly inclined inward, is placed at the front position of the side end face of the movable platform 1a so as to be inclined forward. The lower end of the inclined part 11' is fixed, and the lower end of the rear column 12 is fixed at the rear so that it is inclined outward from the vertical position, and a handrail is installed between the upper ends of the front and rear columns 11 and 12. It is constructed by crossing the rods 13. The handrail rod 13 has a substantially L-shaped bent shape, and includes a straight section 13a extending forward from the upper end of the rear column 12 parallel to the side edge of the movable platform 1a, and a straight section 13a extending forward from the front end of the straight section 13a to the front column 11. It consists of a right-angled curved line portion 13b reaching the upper end.

い。 The peripheral side surface of the handrail rod 8 configured in this way, that is, the rectangular surface formed by the rear strut 12 and the straight part 13a of the handrail rod 13, and the front bent curved portion 13b of the front strut 11 and the handrail rod 13. A side wall panel 14 having an L-shaped cross section and consisting of two orthogonal triangular faces formed by the above is attached between the front and rear supports 11 and 12. That is, the rear support 12 of the side wall panel 14,
Surface 14a corresponding to the straight part 13a of the handrail rod 13
is formed into a quadrilateral shape, and has a front support 11 and a handrail rod 1.
The side wall panel 14 may be attached directly to the front and rear supports 11, 12, or may be attached via an angle-shaped attachment member 15. Furthermore, slits may be provided in the rear surface of the front column 11, the lower surface of the handrail rod 13, and the front surface of the rear column 12, respectively.
The front edge, upper edge, and rear edge of the side wall panel 14 may be inserted into the slits, respectively.

次いで、前記側壁パネル１４の下縁と移動床台

ングル状の底板１６が取り付けられる。 An angled bottom plate 16 is then attached between the lower edge of the side wall panel 14 and the movable platform so as to close the gap between them.

このようにして、側壁パネル１４を取り付けた
手摺杆８を、他の各移動床台１ａ乃至１ｅにも同
様に備える。 In this way, the handrail rod 8 to which the side wall panel 14 is attached is similarly provided to each of the other movable floor stands 1a to 1e.

用される。 In addition, although the above example illustrates the case where the bottom plate 16 is attached between the lower edge of the side wall panel 14 and the movable floor base so as to close the gap between them, FIGS. extend downward,
A case is shown in which the lower edge of the extension part 17 is fixed to the end surface on the side of the movable platform with a set screw 18 or the like, and in this case, the mounting member 15 is used with its direction reversed.

しかして、各移動床台１ａ乃至１ｅを後退移動

順次後段のものの下側に退入して、第２図で示す
ように、垂直棚状に短縮すると共に、手摺枠８が
各々の後段のものの下側に納まるようにする。 Therefore, when each movable platform 1a to 1e is moved backward and shortened, the front columns 11 overlap each other in the front and rear directions, and the rear columns 12 overlap in the lateral direction, so that the front columns 11 and the handrail rods 13 overlap. bending line part 1
3b and the side wall panel 14 arranged on the surface formed by the rear support 12 and the straight part 13a of the handrail rod 13, the side wall panel 14 arranged on the surface formed by the rear strut 12 and the straight part 13a of the handrail rod 13 can be arranged on the front side without interfering with each other in each adjacent movable platform. As shown in FIG. 2, the handrail frame 8 is recessed into the lower side of each subsequent item and shortened into a vertical shelf shape, so that the handrail frame 8 is housed under each subsequent item.

なお、上記実施例では、手摺枠８が、前後支柱
１１，１２の見かけ上の高さを等しくし、手摺杆
１３を水平に横架しているが、後支柱１２を高く
