【産業上の利用分野】[Industrial applications]

本考案は体育館や各種ホ−ル等の建物内の観覧席やステ−ジなどに利用される 椅子収納型床装置に関する。 The present invention relates to a chair storage type floor device used for spectators and stages in buildings such as gymnasiums and various halls.

【０００２】[0002]

【従来の技術】[Prior art]

近年では体育館や各種ホ−ル等の建物の多目的利用の為に、複数の床台を平時 は該建物の床或いはステ−ジとして平坦にして置いて、必要時にはジャッキやリ フト等の押上げ機構により各床台を個々に適当高さずつ押上げて相互に雛段状（ 階段状）の観覧席或いは舞台となせる昇降式床装置が設置利用されるようになっ て来た。 In recent years, for the purpose of multipurpose use of buildings such as gymnasiums and various halls, multiple floor pedestals are laid flat on the floor or stage of the building in normal times, and jacks and lifts are pushed up when necessary. With the use of a mechanism, a lifting floor device has been installed and used, which can push each floor up by an appropriate height individually to form a staircase-like bleaching table or stage.

【０００３】 しかも、こうした昇降式床装置では、観客が腰掛けて楽に観覧できるように各 床台上に椅子を設置したものが多くなって来ている。なお、その椅子は各床台上 に設置したままであると、各床台を平坦にして各種競技や演技等を行なう床面と したり、雛段状のまま各種の演台としたり、或いは立見席として利用するのに、 該椅子が邪魔となる。この為に、本出願人は先に実開平２−９１８５１号公報及 び実開平２−９１８５２号公報に示す椅子収納型床装置を提唱している。Moreover, in such lifting type floor devices, more and more chairs are installed on each floor so that a spectator can sit down and view the floor easily. If the chair is left installed on each floor, each floor may be flattened to serve as a floor surface for various competitions, performances, etc. The chair becomes an obstacle when used as a seat. For this reason, the applicant has previously proposed a chair storage type floor device disclosed in Japanese Utility Model Laid-Open No. 2-91851 and Japanese Utility Model Laid-Open No. 2-91852.

【０００４】 これは、座と背凭れ及び肘掛けが展開状態（座及び肘掛けが略水平状態で背凭 れが後傾状態）から着座者の離席に伴い付勢手段或いは自重により略垂直に自動 復帰する自動折り畳み式椅子を、各床台内に起立したままジャッキやリフト等の 昇降手段により垂直に昇降可能に収納設置すると共に、その各床台の上面床板の 一部に起倒可能に配して前記椅子の昇降による床台上方への迫り出し及び該床台 内への収納を可能とする幅狭な開閉床板部を設けた構成である。This is because the seat, backrest, and armrest are in an expanded state (the seat and armrest are in a substantially horizontal state and the backrest is in a rearward tilted state), and are automatically moved substantially vertically by the biasing means or the self-weight when the seated person leaves the seat. The automatic folding chair that returns to the floor is stored and installed so that it can be vertically moved up and down by elevating means such as jacks and lifts while standing upright in each floor base, and it can be placed up and down on a part of the top floor plate of each floor base. In addition, a narrow opening / closing floor plate portion is provided so that the chair can be lifted up and down to be pushed up above the floor base and stored in the floor base.

【０００５】 また、椅子を床台上方に迫り出した状態で落ち込み防止を図るロック機構を備 えていると共に、椅子と一緒に昇降し前記開閉床板部を押し上げ開放して所定位 置に起立保持したり逆に倒して閉じたりする手摺兼用のガイド及び該ガイドと開 閉床板部の連係用のホルダーを備えている構成である。In addition, a lock mechanism is provided to prevent the chair from falling when it is pushed out above the floor, and the chair is moved up and down to push up and open the open / close floor plate portion to hold it upright at a predetermined position. On the other hand, it is provided with a guide that also serves as a handrail that can be turned upside down and closed, and a holder for linking the guide and the open / close floor plate portion.

【０００６】 こうした構成の椅子収納型床装置であれば、床台に対して自動折り畳み式椅子 が全体的に垂直偏平状態に起立したままジャッキやリフト等の昇降手段により昇 降して出し入れされるので、床台の上面床板はこの一部の幅狭な部分のみを起倒 可能な開閉床板部とすれば良く、しかも、この幅狭な開閉床板部が椅子の昇降に 伴い手摺兼用のガイドと連係用のホルダーを介して自動的に開閉されるので、そ の開閉床板部の開閉操作が簡略化でき、床台に対する椅子の出し入れ作業が非常 に簡便且つ能率的に行ない得る。In the chair-storing floor device having such a configuration, the automatic folding chair is lifted up and down by a lifting means such as a jack or a lift while standing in a vertically flat state as a whole with respect to the floor base. Therefore, the upper floor plate of the floor base may be an opening / closing floor plate part that can be raised and lowered only in this narrow part, and this narrow opening / closing floor plate part also functions as a handrail as the chair is raised and lowered. Since it is automatically opened and closed via the holder for linkage, the opening and closing operation of the opening and closing floor plate portion can be simplified, and the work of taking in and out the chair with respect to the floor base can be performed very easily and efficiently.

【０００７】[0007]

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、前述の如く従来の椅子収納型床装置では、椅子の床台上方へ迫 り出しや該床台内への収納を楽にすべく、座と背凭れ及び肘掛けが常に付勢手段 或いは自重により略垂直に自動復帰する自動折り畳み式椅子を用いていることか ら、床台上に迫り出された椅子に対し観覧者等が着席する際、その椅子の座を略 水平に転倒させることはもちろんのこと、背凭れを後傾状態に、肘掛けを略水平 状態に展開操作する必要があって、その展開操作が面倒であった。特に、手荷物 等で手が塞がっている人は該椅子の展開操作が困難でスムーズに着席できない不 便があった。 However, as described above, in the conventional chair storage floor device, the seat, backrest, and armrests are always biased by the biasing means or by their own weight in order to make it easy to push the chair above the floor base and store it in the floor base. Since an automatic folding chair that automatically returns to a substantially vertical position is used, when a viewer, etc. sits down on a chair that is pushed out on the floor, it is of course not necessary for the chair to fall over in a substantially horizontal position. Therefore, the backrest needs to be tilted backward, and the armrest needs to be deployed in a substantially horizontal state, which is troublesome to deploy. In particular, a person whose hand is blocked by baggage or the like has a difficulty in smoothly operating the chair because it is difficult to deploy the chair.

【０００８】 本考案は上記事情に鑑みなされ、その目的とするところは、椅子が上昇して床 台上に迫り出されると、該椅子の背凭れが後傾状態に、肘掛けが略水平状態に自 動的に展開保持されて、観覧者等が座を押し倒すのみでスムーズに着席でき、当 該椅子を下降して床台内に収納する際には、座と共に背凭れ及び肘掛けが略垂直 に自動復帰して折り畳み状態となって、該椅子の床台内への収納が手間なく行い 得る簡便な椅子収納型床装置を提供することを目的とする。The present invention has been made in view of the above circumstances, and an object of the present invention is that when a chair is lifted and pushed out onto a floor base, the backrest of the chair is tilted backward and the armrests are substantially horizontal. It is automatically unfolded and held so that the viewer can sit down smoothly by pushing down the seat.When the chair is lowered and stored on the floor, the seat and backrest and armrests are placed almost vertically. It is an object of the present invention to provide a simple chair storage type floor device which can be automatically restored to a folded state to store the chair in the floor stand without trouble.

【０００９】[0009]

【課題を解決するための手段】 本考案の椅子収納型床装置は、前記目的を達成するために、座と背凭れ及び肘 掛けが着座者の離席に伴い展開状態から付勢手段或いは自重により略垂直に自動 復帰する自動折り畳み式椅子を、床台内に起立したまま昇降可能に収納設置する と共に、その床台の上面床板の一部に起倒可能に配して前記椅子の昇降による床 台上方への迫り出し及び該床台内への収納を可能とする幅狭な開閉床板部を設け 、且つその開閉床板部の裏面にフックを設け、この開閉床板部を起立開放しなが ら前記椅子を床台上方に迫り出すと、該開閉床板部裏面のフックに係合し、当該 椅子の背凭れを後傾状態に、肘掛けを略水平状態に、展開保持するリンク機構を 設けた構成である。Means for Solving the Problems In order to achieve the above object, a chair storage type floor device of the present invention has a seat, a backrest, and an armrest that are urged by an urging means or a self-weight from a deployed state when a seated person leaves the seat. The self-folding chair that automatically returns to the vertical position is stored and installed in the floor stand so that it can be raised and lowered while standing upright. Provide a narrow open / close floor plate that allows it to be pushed above the floor base and stored in the floor base, and a hook is provided on the back of the open / close floor plate to open and close the open / close floor plate. When the chair is pushed out above the floor base, a link mechanism is provided which engages with a hook on the back surface of the opening / closing floor plate, tilts the backrest of the chair backward, and extends and holds the armrest in a substantially horizontal state. It is a composition.

【作用】[Action]

前記構成により、本考案の椅子収納型床装置では、椅子をジャッキやリフト等 の適宜の昇降手段により上昇して床台上面の床板一部の開閉床板部を起立開放し ながら該床台上に迫り出すと、その開閉床板部の裏面のフックにリンク機構が係 合して、当該椅子の背凭れを後傾状態に、肘掛けを略水平状態に自動的に展開保 持するようになる。これで観覧者等が座を押し倒すだけの簡単な操作でスムーズ に着席できるようになる。その着座者が離席すると、座は付勢手段により跳ね上 がるように略垂直状態に自動復帰するが、背凭れと肘掛けは前記リンク機構によ り展開保持されたままで、再び観覧者等が着席する場合もスムーズである。 With the above configuration, in the chair storage floor device of the present invention, the chair is lifted by an appropriate lifting means such as a jack or a lift to open and close the floor plate part of the floor plate on the upper surface of the floor base while standing on the floor base. When approaching, the link mechanism engages with the hook on the back side of the opening / closing floor plate, and the backrest of the chair is automatically tilted backward, and the armrest is automatically held in a substantially horizontal position. With this, the viewer can easily sit down with a simple operation of pushing down the seat. When the seated person leaves the seat, the seat automatically returns to a substantially vertical state so as to bounce up by the urging means, but the backrest and armrest are unfolded and held by the link mechanism, and the viewer etc. again. It is also smooth when seated.

【００１１】 また、椅子を下降して床台内に収納するときは、観覧者を退去させて、座が略 垂直状態に自動復帰しているのを確認し、この状態で椅子をジャッキやリフト等 の適宜の昇降手段により下降させる。この下降により前記リンク機構が開閉床板 部の裏面のフックから離脱し、これにより背凭れ及び肘掛けが自重或いは付勢手 段により略垂直に自動復帰して、椅子が全体的に垂直偏平な折り畳み状態となり 、そのまま床台内に下降して手間なく収納されるようになる。Further, when the chair is lowered and stored in the floor stand, the spectator is withdrawn, and it is confirmed that the seat automatically returns to the substantially vertical state. In this state, the chair is jacked or lifted. It is lowered by appropriate lifting means such as. Due to this lowering, the link mechanism is disengaged from the hook on the back side of the opening / closing floor plate section, whereby the backrest and armrest automatically return substantially vertically due to their own weight or biasing means, and the chair is in a generally flat and folded state. Then, it will be lowered into the floor as it is and stored without any hassle.

以下、本考案の椅子収納型床装置の一実施例を図面により説明する。図１（ａ ）（ｂ）は椅子収納型床装置の床台１に対する椅子２の昇降時の折り畳み・展開 状態を示す一部断面した側面図、図２（ａ）（ｂ）（ｃ）は同装置の床台１とこ れに収納した椅子２の昇降に伴う出し入れ状態を示す一部断面した側面図、図３ は同装置を背面側から見た概略的斜視図である。 Hereinafter, an embodiment of the chair storage floor device of the present invention will be described with reference to the drawings. 1 (a) and 1 (b) are partially sectional side views showing a folded / unfolded state of a chair 2 with respect to a floor base 1 of a chair storage type floor device, and FIGS. 2 (a), 2 (b) and 2 (c) are FIG. 3 is a partially sectional side view showing a state in which the floor base 1 of the apparatus and a chair 2 housed therein are moved in and out as the chair 2 moves up and down, and FIG. 3 is a schematic perspective view of the apparatus viewed from the rear side.

【００１３】 まず、前記床台１は、体育館やホ−ル等の建物内の床（或いはステ−ジ）部に 多数列設され、各々ジャッキやリフト等の押上げ機構により雛段状に押し上げた り平坦状に下げたりできる昇降式床台であって、図２及び図３に示す如く、複数 本の角鋼管等のビ−ム３を用いて枠組みした左右方向に長い長方体状のもので、 この内部空間の後側略３分の１の部分が椅子収納部Ａとされ、そこに椅子２が収 納設置されている。またその床台１の上面には床板４が敷設されている。この床 板４は前記椅子収納部Ａの上面部分を覆う幅狭な開閉床板部４ａを有し、その開 閉床板部４ａのみが前記椅子２の出し入れを許容すべくヒンジ（図示せず）を介 し前側に起立開閉可能とされ、それ以外の床板部は固定的に設けられている。First, the floor pedestals 1 are arranged in a number of rows on a floor (or stage) in a building such as a gymnasium or a hall, and each floor pedestal 1 is pushed up in a stepwise manner by a pushing mechanism such as a jack or a lift. It is an elevating type floor stand that can be lowered even more flatly, and has a rectangular parallelepiped shape that is long in the left-right direction framed by beams 3 such as square steel pipes as shown in FIGS. 2 and 3. The rearward approximately one-third portion of this internal space is the chair storage A, and the chair 2 is stored and installed therein. A floor plate 4 is laid on the upper surface of the floor base 1. The floor plate 4 has a narrow opening / closing floor plate portion 4a that covers the upper surface of the chair storage portion A, and only the opening / closing floor plate portion 4a has a hinge (not shown) to allow the chair 2 to be taken in and out. It can be opened and closed on the front side through the floor, and the other floor plates are fixedly installed.

【００１４】 こうした床台１内の椅子収納部Ａに椅子２が起立したまま垂直に昇降可能に収 納設置されている。この椅子２は、図１乃至図３に示す如く、複数の座席部を持 つ連結椅子で、後述する取付けベ−ス７に立設した両端の脚２ａ上に貫材（連結 パイプ）２ｂを横架し、この貫材２ｂから複数の支柱２ｃを相互に等間隔を存し て立設し、これら支柱２ｃの各相互間にそれぞれ座２ｄと背凭れ２ｅを設けると 共に、各支柱２ｃの上端部に肘掛け２ｆを設けたものである。The chair 2 is stored and installed in the chair storage portion A in the floor base 1 so that the chair 2 can be vertically moved up and down. As shown in FIGS. 1 to 3, this chair 2 is a connecting chair having a plurality of seats, and a penetrating member (connecting pipe) 2b is provided on legs 2a at both ends which are erected on a mounting base 7 described later.

The chair 2 is held in its standing state without falling down, and when the chair 2 descends, the chair 2 is rotated so as to fall backward so as to follow it, and is automatically closed.

【００２０】 なお、前記ロック機構１１及びこのロック解除手段や前記手摺兼用のガイド１ ５並びにホルダー１６の詳細な説明は、前述の実開平２−９１８５１号及び実開 平２−９１８５２号の明細書中に詳しく開示されているので省略する。A detailed description of the lock mechanism 11, the lock releasing means, the guide 15 also serving as the handrail, and the holder 16 is given in the specifications of the above-mentioned Japanese Utility Model Publication No. 2-91851 and Japanese Utility Model Publication No. 2-91852. Since it is disclosed in detail inside, it is omitted.

【００２１】 ここで、前記床台１上面の開閉床板部４ａの裏面両端寄り部には、図１及び図 ３に示す如く逆Ｌ字形のフック１８がそれぞれ設けられている。 一方、前記自動折り畳み式連結椅子２の各座席の背凭れ２ｅと肘掛け２ｆとを 連動するリンク機構６は、図１に示す如く、各支柱２ｃの上端後部に固定したピ ン６ａを支点に肘掛け２ｆと一体に回動する第１リンク６ｂと、この第１リンク ６ｂの後端にピン６ｃを介し上端を連結して背凭れ２ｅと一体に回動する第２リ ンク６ｄと、この第２リンク６ｄの下端にピン６ｆを介し後端を連結し且つ支柱 ２の下端寄り部のピン６ｇを支点に回動する第３リンク６ｈとを備えた構成であ る。しかも、その連結椅子２の両端側にそれぞれ配したリンク機構６は、前記第 ３リンク６ｈの前端側に固定されて更に前方に延出する一対ずつの係合アーム６ ｊを有し、これら一対ずつの係合アーム６ｊ先端に係脱ピン６ｋを有している。 これで前記開閉床板部４ａを前述の如く起立開放しながら連結椅子２を床台１上 方に迫り出すと、該開閉床板部４ａ裏面の両端寄りのフック１８に該係脱ピン６ ｋが下側から係合して、第３リンク６ｈを背凭れ２ｅと共に押し上げるように回 動させて、該背凭れ２ｅを後傾状態に、肘掛け２ｆを略水平状態に、展開保持す るようになっている。Here, as shown in FIGS. 1 and 3, inverted L-shaped hooks 18 are provided on the upper and lower floor plate portions 4a on the upper surface of the floor base 1 at positions near both ends of the rear surface. On the other hand, as shown in FIG. 1, the link mechanism 6 for interlocking the backrest 2e and the armrest 2f of each seat of the automatic folding connecting chair 2 has an armrest with a pin 6a fixed to the upper rear portion of each strut 2c as a fulcrum, as shown in FIG. 2f, a first link 6b that rotates integrally with the back 2f, a second link 6d that connects the upper end of the first link 6b to the rear end of the first link 6b via a pin 6c, and rotates integrally with the backrest 2e, and the second link 6d. The rear end of the link 6d is connected to the lower end of the link 6d via a pin 6f, and a third link 6h that rotates about a pin 6g near the lower end of the column 2 is used as a fulcrum. Moreover, the link mechanisms 6 arranged on both end sides of the connecting chair 2 respectively have a pair of engaging arms 6 j fixed to the front end side of the third link 6 h and extending further forward. Each engaging arm 6j has an engaging / disengaging pin 6k. As a result, when the connecting chair 2 is pushed out to the upper side of the floor base 1 while the opening / closing floor plate portion 4a is opened upright as described above, the engagement / disengagement pin 6k is lowered to the hooks 18 on both sides of the rear surface of the opening / closing floor plate portion 4a. From the side, the third link 6h is rotated so as to be pushed up together with the backrest 2e so that the backrest 2e is tilted backward and the armrest 2f is held substantially horizontally. There is.

【００２２】 而して、前述した構成の椅子収納型床装置では、椅子付き観覧席とする場合に は、まず各床台１をジャッキやリフト等の押上げ機構により雛段状に押し上げる 。その後、その各段の床台１内の連結椅子２を取付けベース７ごと適宜昇降手段 により上昇させる。これで、該連結椅子２と一緒に上昇する手摺兼用ガイド１５ と連係用ホルダー１６を介し床板４の幅狭な開閉床板部４ａが図２（ａ）の状態 から図２（ｂ）の状態に押し上げられ、更に図１（ａ）に示す垂直な起立状態に 押し上げられて開放保持させる。この状態で更に連結椅子２が上昇せしめられて 床台１上方に迫り出すようになる。In the chair-storing floor device having the above-described configuration, when the pedestal with a chair is used, first, each floor pedestal 1 is pushed up in a tiered manner by a pushing mechanism such as a jack or a lift. After that, the connecting chairs 2 in the floor pedestals 1 at the respective stages are lifted together with the mounting base 7 by the elevating means. With this, the narrow opening / closing floor plate portion 4a of the floor plate 4 is changed from the state of FIG. 2 (a) to the state of FIG. 2 (b) through the handrail-cum-guide 15 that rises together with the connecting chair 2 and the linking holder 16. It is pushed up and further pushed up to the vertical standing state shown in FIG. 1 (a) to hold it open. In this state, the connecting chair 2 is further raised so as to push out above the floor base 1.

【００２３】 この連結椅子２が所定高さ近くまで上昇して来ると、図１（ａ）に示す如く、 両端側のリンク機構６の係合アーム６ｊ先端の係脱ピン６ｋが前記開閉床板部４ ａ裏面の両端寄りのフック１８の真下に移動し、更に連結椅子２の最終上昇段階 で該係脱ピン６ｋがフック１８に係合して図１（ｂ）に示す如く第３リンク６ｈ を背凭れ２ｅと共に押し上げるように回動させる。これで各座席部の背凭れ２ｅ が後傾状態に、肘掛け２ｆが略水平状態に、展開保持される。When the connecting chair 2 rises to a height close to a predetermined height, as shown in FIG. 1A, the engagement / disengagement pins 6k at the ends of the engaging arms 6j of the link mechanisms 6 on both end sides cause the opening / closing floor plate portion. 4a It moves to the position just below the hooks 18 on both sides of the back surface, and at the final raising stage of the connecting chair 2, the engagement / disengagement pin 6k engages with the hooks 18 to move the third link 6h as shown in FIG. 1 (b). The backrest 2e is rotated so as to push it up. As a result, the backrest 2e of each seat is tilted backward and the armrest 2f is held substantially horizontally.

【００２４】 以上で椅子付き観覧席としてのセット作業が終了し、観客は各段の床台１上に 来て、連結椅子２の各座席部の背凭れ２ｅは後傾状態に、肘掛け２ｆは略水平状 態に展開保持されているので、座２ｄを前に押し倒すだけの簡単な操作でスムー ズに着席できて安楽に観覧できるようになる。その着座者が離席すると、座２ｄ は付勢手段により跳ね上がるように略垂直状態に自動復帰するが、背凭れ２ｅと 肘掛け２ｆは前記リンク機構６により展開保持されたままで、再び観覧者等が着 席する場合もスムーズである。With the above, the setting work as the bleachers with chairs is completed, the spectators come to the floors 1 of the respective steps, the backrests 2e of the seat portions of the connecting chairs 2 are tilted backward, and the armrests 2f are Since it is unfolded and held in a substantially horizontal state, it is possible to sit down smoothly and view it easily by simply pushing down the seat 2d. When the seated person leaves the seat, the seat 2d automatically returns to a substantially vertical state so as to bounce up by the biasing means, but the backrest 2e and the armrest 2f are unfolded and held by the link mechanism 6, and the viewer or the like again. It is smooth when you sit down.

【００２５】 また、連結椅子２を下降して床台１内に収納するときは、観覧者を退去させて 、座２ｄが略垂直状態に自動復帰しているのを作業員が確認すると共に、ロック 機構１１のロック解除操作を行なう。この状態で連結椅子２を取付けベ−ス７並 びに手摺兼用ガイド１５と一緒にジャッキやリフト等の適宜の昇降手段により下 降させる。In addition, when the connecting chair 2 is lowered and stored in the floor base 1, the worker retreats and the operator confirms that the seat 2d is automatically returned to the substantially vertical state. The lock release operation of the lock mechanism 11 is performed. In this state, the connecting chair 2 is lowered together with the mounting base 7 and the guide 15 also serving as a handrail by an appropriate lifting means such as a jack or a lift.

【００２６】 この連結椅子２の下降により前記両端側のリンク機構６の係脱ピン６ｋが前記 開閉床板部４ａ裏面の両端寄りのフック１８から下方に離脱して、第３リンク６ ｈを背凭れ２ｅと共に押し上げる力が無くなり、これで各座席部の背凭れ２ｅと 肘掛け２ｆとが自重により略垂直状態に自動復帰して、椅子２が全体的に垂直偏 平な折り畳み状態となり、そのまま床台１内に下降して手間なく収納されるよう になる。As the connecting chair 2 descends, the engagement / disengagement pins 6k of the link mechanisms 6 on the both ends are separated downward from the hooks 18 on the rear surface of the opening / closing floor plate portion 4a near both ends, and the third link 6h is supported. There is no force to push up together with 2e, so that the backrest 2e of each seat and the armrest 2f automatically return to a substantially vertical state due to their own weight, and the chair 2 becomes a vertically flat folded state as a whole, and the floor stand 1 remains as it is. It descends inside and can be stored easily.

【００２７】 これと同時に開閉床板部４ａがホルダ−１６を介し手摺兼用ガイド１５に連動 して後側に転倒して閉成するようになる。これで各床台１は椅子など一切上側に 突出するものがない平坦な床板４が得られて、雛段状のままの各種演台や或いは 立見席として利用できるようになる。At the same time, the opening / closing floor plate portion 4a interlocks with the handrail / combined guide 15 through the holder 16 and falls to the rear side to be closed. As a result, each floor stand 1 has a flat floor board 4 having no chair or the like protruding upwards, and can be used as various podiums in the form of a step or as a standing seat.

【００２８】 更にその状態から各床台１をジャッキやリフト等の押上げ機構により下降させ て全て同一高さとすることで、各種競技や演技等を行なう平坦な床面が構成でき るようになる。Further, from this state, each floor base 1 is lowered by a lifting mechanism such as a jack or a lift so that all the floors have the same height, so that a flat floor surface for various competitions and performances can be constructed. .
