Description

【０００１】
【発明の属する技術分野】
本発明は、固定屋根に形成した開口部を可動屋根の移動によって開閉する開閉屋根の開閉移動部構造に関する。
【０００２】
【従来の技術】
開閉屋根は、例えば特開平１０−２９９１５５号公報に開示されるように、固定屋根に形成した開口部を可動屋根が移動して開閉するようになっている。このとき、可動屋根は両端部に設けた車輪が、開口部の両側辺に設けたレールを転動することにより、円滑に移動できるようになっている。
【０００３】
ところで、従来用いられる可動屋根は、図７（ａ）に示すように上方に湾曲してアーチ構造となった可動屋根１や同図（ｂ）に示すように平坦なフラット構造となった可動屋根２がある。これら可動屋根１，２は図８に示すようなキールアーチや固定屋根３の構造梁等の可動屋根支持部材４で支持したり、図示省略したが観戦用スタンドの柱・梁により支持したりする場合がある。尚、上記固定屋根３はドーム屋根として構築され、図８では開閉屋根全体を楕円形状として示してあり、また、可動屋根１，２によって開閉される開口部５は開閉屋根の長軸方向に形成されている。
【０００４】
【発明が解決しようとする課題】
しかしながら従来の開閉屋根では、アーチ構造となった可動屋根１では、図７（ａ）に示したように自重により開き方向に変形力が作用し、両端部には外向きのスラスト力Ｆ1が発生するとともに、フラット構造の可動屋根２では、同図（ｂ）に示したように中央部が垂れ下がる方向の変形力が作用し、両端部には内向きの引張力Ｆ2 が発生する。このため、可動屋根１，２の両端部を支持する可動屋根支持部材４には、上記スラスト力Ｆ1や引張力Ｆ2等の水平力が作用することになる。また、環境温度の変化や風による吹き上げ力あるいは吹き下げ力によっても、同様の力が作用することになる。
【０００５】
つまり、アーチ構造の可動屋根１では可動屋根支持部材４にスラスト力Ｆ1 が作用すると、この可動屋根支持部材４は開口部５の幅を広げる方向に横移動し、この横移動によって可動屋根１は更に開き方向に大きく変形することになる。このように可動屋根１が更に開き変形されると、該可動屋根１を構成する構造部材の応力が大きく増加することになる。また、上記可動屋根支持部材４の横移動量は、図８に示したように複数の移動屋根１が移動する際に、複数枚が近接した部分Ｐではそれぞれのスラスト力Ｆ1 が集合されるため大きくなり、かつ単独枚が離隔した部分Ｑでは小さくなる。このため、固定屋根３や可動屋根１の軽量化の要求によって各部材の剛性を必要最小限度に抑えようとする際に、可動屋根１個々の変形量および構造部材の応力を正確に把握することは著しく困難になる。このような状況の中で固定屋根３および可動屋根１を軽量化した場合には、予期しない変形や過大応力が発生して可動屋根１の車輪が可動屋根支持部材４に設けた図外のレールから脱輪する等のおそれがある。
【０００６】
また、フラット構造の可動屋根２にあっても、両端部に発生する上記引張力Ｆ2によって可動屋根支持部材４が開口部５の幅を狭める方向に横移動されるため、上記アーチ構造の可動屋根１の場合と同様に該フラット構造の可動屋根２の変形量や部材応力の把握が著しく困難になってしまうという課題があった。
【０００７】
そこで、本発明はかかる従来の課題に鑑みて成されたもので、可動屋根支持部材の横移動変形を吸収して可動屋根の支持点移動を阻止するとともに、該可動屋根から可動屋根支持部材に及ぼす水平力を一定に保持することにより、可動屋根の変形および部材応力を一定値に保って、屋根部分の軽量化を達成した場合にも可動屋根の円滑な開閉作動を可能とする開閉屋根の開閉移動部構造を提供することを目的とする。
【０００８】
【課題を解決するための手段】
かかる目的を達成するために、本発明の請求項１に係る開閉屋根の開閉移動部構造は、固定屋根に形成された開口部の相対向する側辺間に可動屋根が移動自在に配置される開閉屋根において、上記可動屋根の支持部に、該可動屋根が上記開口部の上記側辺方向へ移動するのを阻止する水平方向規制部材と、該可動屋根の荷重を支持する鉛直方向規制部材とを設けるとともに、上記水平方向規制部材に、これの規制方向の相対変位を許容する変位許容隙間を設け、この変位許容隙間に、変形量に対して荷重変動が略一定の荷重一定領域のばね特性を備えたばね部材を、該ばね特性が前記荷重一定領域に設定された状態で介装したことを特徴とする。
【０００９】
この構成によれば、可動屋根は水平方向規制部材および鉛直方向規制部材によって位置規制されつつ開口部の相対向する側辺に沿って開閉移動するようになっており、可動屋根の支持部に開口部の側辺方向への水平力が作用して開口部の両側辺が横移動した場合に、この両側辺の横移動は変位許容隙間に介装したばね部材の変形によって吸収され、可動屋根の支持点が移動するのを阻止することができる。また、このばね部材は、荷重一定領域のばね特性を備え、ばね特性が前記荷重一定領域に設定された状態で変位許容隙間に介装されているので、可動屋根から固定屋根に及ぼす水平力を一定に保持し、水平方向規制部材および鉛直方向規制部材と固定屋根との相対位置が変化するのを防止できる。従って、屋根部分の軽量化を図るために可動屋根の変形および部材応力を当初の設計値通りに施工した場合にも、可動屋根は脱輪したり落下することなく円滑に開閉作動される。
【００１０】
【発明の実施の形態】
以下、本発明の実施形態を添付図面を参照して詳細に説明する。図１〜図６は本発明の開閉屋根の開閉移動部構造の一実施形態を示し、図１は開閉屋根の片側部分の断面図、図２は可動屋根の支持部の平面図、図３は該支持部の正面図、図４は図２中Ａ−Ａ線断面図、図５は図２中Ｂ−Ｂ線断面図、図６は皿ばねのばね特性図である。
【００１１】
本発明の開閉屋根の開閉移動部構造の基本構成は、固定屋根１６に形成された開口部１８の相対向する側辺間に跨って可動屋根１２，１４が移動自在に配置される開閉屋根１０において、上記可動屋根１２，１４の支持部２６に、該可動屋根１２，１４の上記開口部１８の上記側辺方向へ移動するのを阻止する水平方向規制部材３２と、該可動屋根１２，１４の荷重を支持する鉛直方向規制部材３４とを設けるとともに、上記水平方向規制部材３２に、これの規制方向の相対変位を許容する変位許容隙間δを設け、この変位許容隙間δに、変形量に対して荷重変動が略一定となる荷重一定領域Ｒのばね特性Ｓを備えたばね部材５２を介装し、このばね部材５２の荷重一定領域Ｒによって上記変位許容隙間δの相対変位部分を弾発支持する。
【００１２】
即ち、本実施形態の開閉移動部構造を備えた開閉屋根１０は、図１に示すように可動屋根１２，１４が上下２段に配置された場合を示し、各可動屋根１２，１４は同様の構造をもって固定屋根１６側に支持され、この固定屋根１６に形成した開口部１８を開閉するようになっている。固定屋根１６には開口部１８の両側に沿って鉛直壁２０が設けられ、この鉛直壁２０の内面には上下２段に棚板２２，２４が水平に設けられ、これら鉛直壁２０および棚板２２，２４の結合体が開口部１８の側辺となって配置される。それぞれの棚板２２，２４の上面には、上記可動屋根１２，１４がそれぞれ支持部２６を介して移動自在に支持される。
【００１３】
上記可動屋根１２，１４の各支持部２６は同様の構成となり、その１つを図２〜図５に示す。この支持部２６は図１に示したトラス構造として構成される屋根本体２８の端部を取り付ける支持部本体３０と、この支持部本体３０の側方に設けられる水平方向規制部材としての水平車輪３２と、支持部本体３０の下方に設けられる鉛直方向規制部材としての鉛直車輪３４とを備える。水平車輪３２および鉛直車輪３４はそれぞれ２個が１組となり、それぞれは車輪支持部材３６，３８に回転自在に取り付けられる。各車輪支持部材３６，３８の中央部は、上記支持部本体３０の側方および下方からそれぞれ突設されるブラケット４０，４２にピン４４，４６を介して回動自在に取り付けられている。
【００１４】
ここで、上記水平車輪３２を取り付けた上記ブラケット４０を、上記支持部本体３０にボルト４８を介して相対移動可能に取り付ける。即ち、ブラケット４０は、その中央部にボルト４８を摺動自在に挿通してこれの頭部４８ａに係止させるとともに、このブラケット４０と支持部本体３０との間に変位許容隙間δを設けてボルト４８のねじ部４８ｂを支持部本体３０にナット５０で止める。これによってブラケット４０は、水平車輪３２とともに上記変位許容隙間δの範囲内で支持部本体３０に対して相対移動が可能となっている。
【００１５】
上記変位許容隙間δには、ばね部材としての皿ばね５２が上記ボルト４８に挿通されて介装され、この皿ばね５２によってブラケット４０が支持部本体３０から離れる方向に押圧されて弾発支持される。本実施形態では上記皿ばね５２は４枚が使用され、これら皿ばね５２は隣接されるものどうしで表裏が交互に配置される。皿ばね５２は図６に示す非線形のばね特性Ｓを備え、変形量ｘに対して荷重Ｐ変動が略一定となる荷重一定領域Ｒが存在し、そして、上記変位許容隙間δに介装された状態で皿ばね５２は該荷重一定領域Ｒに設定される。
【００１６】
上記鉛直壁２０および上記棚板２２，２４には、水平車輪３２および鉛直車輪３４に対応する位置に第１レール５４および第２レール５６が開口部１８の両側辺に沿って連続して配置され、第１レール５４に水平車輪３２が当接して転動するとともに、第２レール５６に鉛直車輪３４が当接して転動する。そして、水平車輪３２が第１レール５４に当接することにより、可動屋根１２，１４の開口部１８両側方向（図１中左右方向）の移動を阻止するとともに、鉛直車輪３４は第２レール５６に当接して可動屋根１２，１４の荷重を支持する。
【００１７】
ところで、上記車輪支持部材３６には、鉛直壁２０に対向する側の中央部に鍔部５８を設ける一方、該鉛直壁２０には鍔部５８に係合する１対のＬ字状ストッパー６０を、車輪支持部材３６を両側から挟むように固定し、水平車輪３２が第１レール５４から離れる方向の移動を阻止してある。また、同様に車輪支持部材３８の棚板２２，２４側中央部に鍔部６２を設けるとともに、棚板２２，２４に該鍔部６２に係合する１対のＬ字状ストッパー６４を固定し、鉛直車輪３４が浮き上がるのを阻止してある。
【００１８】
以上の構成により本実施形態の開閉屋根の開閉移動部構造にあっては、可動屋根１２，１４が図外の駆動手段、例えばウインチに巻き取られるロープを接続するなどして移動することにより、開口部１８を開閉することができる。これら可動屋根１２，１４の移動時には、水平車輪３２が第１レール５４に当接して転動することにより、開口部１８両側方向の位置が規制されるとともに、鉛直車輪３４は可動屋根１２，１４の荷重を支持しつつ第２レール５６を転動する。
【００１９】
従って、可動屋根１２，１４の両端部にスラスト力や引張力等の水平力が作用した場合に、この水平力は水平車輪３２が第１レール５４を押圧する方向または引き離す方向に作用する。このとき、本実施形態では変位許容隙間δを設けて皿ばね５２を介装してあるので、上記第１レール５４を横移動させる水平力は皿ばね５２が変形しつつ変位許容隙間δが相対変位（δの間隔変化）することで吸収される。また、上記皿ばね５２のばね特性は荷重一定領域Ｒに設定されているため、可動屋根１２，１４から開口部１８の両側辺、つまり鉛直壁２０に作用する水平力を一定に保持することができる。従って、可動屋根１２，１４の変形および部材応力を当初の設計値に保って施工した場合にも、鉛直車輪３４が開口部１８の両側方向に位置変化することがないので、鉛直車輪３４は脱輪することなく第２レール５６を転動する状態を維持し、可動屋根１２，１４を円滑に移動する。
【００２０】
また、上記皿ばね５２を設けたことにより、地震による水平方向の振動を効果的に吸収することができる。このとき、図１に示すように上記皿ばね５２と並列関係をもってオイルダンパー等の粘性減衰部材７０を設置することにより、この粘性減衰部材７０によって地震振動を減衰できる。
【００２１】
ところで、本実施形態では可動屋根１２，１４を２段に構成したが、これに限ることなく可動屋根は１段または３段以上の複数段に構成したものにあって本発明を適用できることは勿論である。
【００２２】
また、上記皿ばね５２は４枚用いた場合を示したが、この枚数に限ることなく皿ばね５２の許容支持力に応じてその枚数を任意に決定することができる。このとき、ばね部材としては皿ばね５２に限ることなく、荷重一定領域Ｒを備える限りにおいていかなる種類のばね、例えばコイルスプリングや板ばねを用いることもできる。
【００２３】
更に、水平方向規制部材および鉛直方向規制部材として水平車輪３２および鉛直車輪３４を用いた場合を示したが、これら車輪に代えて摺動部材やベアリングを用いたころ部材等を用いても構成することができる。
【００２４】
【発明の効果】
以上、説明したように、本発明の開閉屋根の開閉移動部構造にあっては、水平方向規制部材に設けた変位許容隙間に荷重一定領域を備えたばね部材を介装したので、開口部の相対向する側辺に作用する水平力はばね部材の変形によって吸収され、可動屋根の支持点が移動するのを阻止することができる。また、このばね部材は荷重一定領域のばね特性を備え、このばね特性が前記荷重一定領域に設定された状態で変位許容隙間に介装されるので、可動屋根から固定屋根に及ぼす水平力を一定に保持し、水平方向規制部材および鉛直方向規制部材と固定屋根との相対位置が変化するのを防止できる。従って、可動屋根の変形及び部材応力を当初の設計通りに施工して屋根部分の軽量化を図った場合にも、可動屋根の脱輪や落下を防止して、円滑に開閉作動させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to an opening / closing moving part structure of an open / close roof that opens and closes an opening formed in a fixed roof by moving the movable roof.
[0002]
[Prior art]
For example, as disclosed in JP-A-10-299155, the open / close roof is opened and closed by moving the movable roof through an opening formed in the fixed roof. At this time, the movable roof is configured so that the wheels provided at both ends can move smoothly by rolling the rails provided on both sides of the opening.
[0003]
By the way, the movable roof used conventionally is the movable roof 1 curved upward and having an arch structure as shown in FIG. 7A, or the movable roof having a flat flat structure as shown in FIG. 7B. There are two. These movable roofs 1 and 2 are supported by a movable roof support member 4 such as a keel arch or a structural beam of the fixed roof 3 as shown in FIG. 8, or are supported by pillars and beams of a spectator stand although not shown. There is a case. The fixed roof 3 is constructed as a dome roof. In FIG. 8, the entire open / close roof is shown as an ellipse, and the opening 5 opened and closed by the movable roofs 1 and 2 is formed in the longitudinal direction of the open / close roof. Has been.
[0004]
[Problems to be solved by the invention]
However, in the conventional open / close roof, in the movable roof 1 having an arch structure, as shown in FIG. 7A, a deformation force acts in the opening direction by its own weight, and an outward thrust force F1 is generated at both ends. At the same time, in the movable roof 2 having a flat structure, as shown in FIG. 2B, a deformation force in the direction in which the central portion hangs down acts, and an inward tensile force F2 is generated at both ends. For this reason, horizontal forces such as the thrust force F1 and the tensile force F2 act on the movable roof support member 4 that supports both ends of the movable roofs 1 and 2. A similar force is also exerted by a change in environmental temperature and a blowing or blowing force caused by wind.
[0005]
That is, in the movable roof 1 having the arch structure, when the thrust force F1 is applied to the movable roof support member 4, the movable roof support member 4 is laterally moved in the direction in which the width of the opening 5 is increased. Furthermore, it will greatly deform in the opening direction. When the movable roof 1 is further opened and deformed as described above, the stress of the structural members constituting the movable roof 1 greatly increases. Further, the amount of lateral movement of the movable roof support member 4 is that, as shown in FIG. 8, when the plurality of movable roofs 1 are moved, the respective thrust forces F1 are gathered in the portion P where the plurality of roofs are close to each other. It becomes larger and becomes smaller in the portion Q where the single sheet is separated. For this reason, when it is going to suppress the rigidity of each member to the required minimum by the request | requirement of weight reduction of the fixed roof 3 or the movable roof 1, correctly grasping | ascertaining the deformation of each movable roof 1 and the stress of a structural member. Becomes extremely difficult. When the fixed roof 3 and the movable roof 1 are reduced in weight in such a situation, unexpected deformation and excessive stress occur, and the rails of the movable roof 1 provided on the movable roof support member 4 are not shown in the figure. There is a risk of escaping from the wheel.
[0006]
Even in the flat movable roof 2, the movable roof support member 4 is laterally moved in the direction of narrowing the width of the opening 5 by the tensile force F 2 generated at both ends. As in the case of No. 1, there is a problem that it becomes extremely difficult to grasp the deformation amount and member stress of the movable roof 2 having the flat structure.
[0007]
Therefore, the present invention has been made in view of such conventional problems, and absorbs the lateral movement deformation of the movable roof support member to prevent the support point movement of the movable roof, and from the movable roof to the movable roof support member. By maintaining the applied horizontal force constant, the movable roof can be smoothly opened and closed even when the weight of the roof is reduced by keeping the deformation and member stress of the movable roof constant. An object is to provide an open / close moving part structure.
[0008]
[Means for Solving the Problems]
In order to achieve such an object, in the opening / closing moving part structure of the opening / closing roof according to claim 1 of the present invention, the movable roof is movably disposed between the opposite sides of the opening formed in the fixed roof. In the openable and closable roof, a horizontal direction restricting member that prevents the movable roof from moving in the side direction of the opening, and a vertical direction restricting member that supports the load of the movable roof. The horizontal regulating member is provided with a displacement allowance gap that allows relative displacement in the restricting direction, and the displacement characteristic gap has a spring characteristic in a load constant region in which the load fluctuation is substantially constant with respect to the deformation amount. A spring member provided with a spring characteristic is interposed in a state where the spring characteristic is set in the constant load region .
[0009]
According to this configuration, the movable roof is configured to open and close along the opposite sides of the opening while being position-regulated by the horizontal direction regulating member and the vertical direction regulating member, and is opened to the support part of the movable roof. When the horizontal force in the lateral direction of the part acts and both sides of the opening move laterally, the lateral movement of both sides is absorbed by the deformation of the spring member interposed in the displacement allowance gap, and the movable roof The support point can be prevented from moving. In addition, this spring member has a spring characteristic of a constant load region, and is interposed in the displacement allowance gap in a state where the spring characteristic is set in the constant load region, so that a horizontal force exerted on the fixed roof from the movable roof is obtained. It can hold | maintain constant and it can prevent that the relative position of a horizontal direction control member and a vertical direction control member, and a fixed roof changes. Therefore, even when the deformation of the movable roof and the member stress are applied according to the original design values in order to reduce the weight of the roof portion, the movable roof can be smoothly opened and closed without being removed or dropped.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 to 6 show an embodiment of the opening and closing moving part structure of the opening and closing roof of the present invention, FIG. 1 is a sectional view of one side portion of the opening and closing roof, FIG. 2 is a plan view of a support part of the movable roof, and FIG. FIG. 4 is a cross-sectional view taken along the line AA in FIG. 2, FIG. 5 is a cross-sectional view taken along the line BB in FIG. 2, and FIG.
[0011]
The basic structure of the opening / closing moving part structure of the opening / closing roof of the present invention is the opening / closing roof 10 in which the movable roofs 12, 14 are movably disposed across the opposing sides of the opening 18 formed in the fixed roof 16. The horizontal direction regulating member 32 that prevents the support 26 of the movable roofs 12 and 14 from moving in the lateral direction of the opening 18 of the movable roofs 12 and 14, and the movable roofs 12 and 14. The horizontal direction regulating member 32 is provided with a displacement allowance gap δ that allows relative displacement in the restricting direction, and the displacement allowance gap δ has a deformation amount. On the other hand, a spring member 52 having a spring characteristic S of a constant load region R in which the load fluctuation is substantially constant is interposed, and the relative displacement portion of the displacement allowance gap δ is elastically supported by the constant load region R of the spring member 52. To do.
[0012]
That is, the open / close roof 10 provided with the open / close moving part structure of this embodiment shows a case where the movable roofs 12 and 14 are arranged in two upper and lower stages as shown in FIG. The structure is supported on the fixed roof 16 side, and the opening 18 formed in the fixed roof 16 is opened and closed. The fixed roof 16 is provided with vertical walls 20 along both sides of the opening 18, and shelf plates 22, 24 are horizontally provided on the inner surface of the vertical wall 20 in two upper and lower levels. A combined body of 22 and 24 is arranged on the side of the opening 18. The movable roofs 12 and 14 are movably supported on the upper surfaces of the respective shelf plates 22 and 24 via support portions 26, respectively.
[0013]
Each support part 26 of the said movable roof 12 and 14 becomes the same structure, The one is shown in FIGS. This support portion 26 is a support portion main body 30 to which the end portion of the roof main body 28 configured as the truss structure shown in FIG. 1 is attached, and a horizontal wheel 32 as a horizontal direction regulating member provided on the side of the support portion main body 30. And a vertical wheel 34 as a vertical direction regulating member provided below the support body 30. Two sets of the horizontal wheel 32 and the vertical wheel 34 form one set, and each is rotatably attached to the wheel support members 36 and 38. The central portions of the wheel support members 36 and 38 are rotatably attached to brackets 40 and 42 projecting from the side and bottom of the support portion main body 30 via pins 44 and 46, respectively.
[0014]
Here, the bracket 40 to which the horizontal wheel 32 is attached is attached to the support body 30 via a bolt 48 so as to be relatively movable. That is, the bracket 40 is slidably inserted into the central portion of the bracket 40 and locked to the head portion 48a thereof, and a displacement allowance gap δ is provided between the bracket 40 and the support portion main body 30. The threaded portion 48 b of the bolt 48 is fastened to the support portion main body 30 with a nut 50. As a result, the bracket 40 can move relative to the support portion main body 30 within the range of the allowable displacement gap δ together with the horizontal wheel 32.
[0015]
A disc spring 52 as a spring member is inserted through the bolt 48 in the displacement allowance gap δ, and the bracket 40 is pressed in a direction away from the support body 30 by the disc spring 52 to be elastically supported. The In the present embodiment, four disc springs 52 are used, and these disc springs 52 are alternately arranged on the front and back sides of adjacent ones. The disc spring 52 has a non-linear spring characteristic S shown in FIG. 6, has a constant load region R in which the load P fluctuation is substantially constant with respect to the deformation amount x, and is interposed in the displacement allowance gap δ. In this state, the disc spring 52 is set to the constant load region R.
[0016]
On the vertical wall 20 and the shelves 22 and 24, a first rail 54 and a second rail 56 are continuously arranged along the both sides of the opening 18 at positions corresponding to the horizontal wheels 32 and the vertical wheels 34. The horizontal wheel 32 contacts and rolls on the first rail 54, and the vertical wheel 34 contacts and rolls on the second rail 56. The horizontal wheel 32 abuts on the first rail 54, thereby preventing the movement of the movable roofs 12 and 14 in the directions on both sides of the opening 18 (left and right direction in FIG. 1), and the vertical wheel 34 on the second rail 56. It abuts and supports the load of the movable roofs 12 and 14.
[0017]
By the way, the wheel support member 36 is provided with a flange portion 58 at the center portion on the side facing the vertical wall 20, and the vertical wall 20 is provided with a pair of L-shaped stoppers 60 that engage with the flange portion 58. The wheel support member 36 is fixed so as to be sandwiched from both sides, and the horizontal wheel 32 is prevented from moving away from the first rail 54. Similarly, a hook 62 is provided at the center of the wheel support member 38 on the side of the shelves 22, 24, and a pair of L-shaped stoppers 64 that engage with the hook 62 are fixed to the shelves 22, 24. The vertical wheel 34 is prevented from floating.
[0018]
With the above-described configuration, in the opening / closing moving part structure of the opening / closing roof of the present embodiment, the movable roofs 12 and 14 move by connecting a driving means (not shown), for example, a rope wound around a winch, The opening 18 can be opened and closed. When the movable roofs 12 and 14 are moved, the horizontal wheels 32 abut against the first rail 54 and roll, so that the positions of both sides of the opening 18 are regulated and the vertical wheels 34 are moved to the movable roofs 12 and 14. The second rail 56 is rolled while supporting the load.
[0019]
Accordingly, when a horizontal force such as a thrust force or a tensile force is applied to both ends of the movable roofs 12 and 14, the horizontal force acts in a direction in which the horizontal wheel 32 presses or separates the first rail 54. At this time, in the present embodiment, the disc allowable spring δ is provided and the disc spring 52 is interposed. Therefore, the horizontal force for laterally moving the first rail 54 is deformed while the disc allowable spring δ is deformed. Absorbed by displacement (change in interval of δ). Further, since the spring characteristic of the disc spring 52 is set in the constant load region R, the horizontal force acting on both sides of the opening 18 from the movable roofs 12 and 14, that is, the vertical wall 20 can be kept constant. it can. Therefore, even when the construction is performed with the deformation of the movable roofs 12 and 14 and the member stress maintained at the original design values, the vertical wheels 34 are not displaced in both directions of the opening 18, so the vertical wheels 34 are removed. The state which rolls the 2nd rail 56, without rolling is maintained, and the movable roofs 12 and 14 are moved smoothly.
[0020]
Further, by providing the disc spring 52, it is possible to effectively absorb horizontal vibration caused by an earthquake. At this time, as shown in FIG. 1, by installing a viscous damping member 70 such as an oil damper in parallel with the disc spring 52, seismic vibration can be attenuated by the viscous damping member 70.
[0021]
By the way, although the movable roofs 12 and 14 are configured in two stages in the present embodiment, the present invention can be applied to a movable roof having one stage or a plurality of stages of three or more without being limited to this. It is.
[0022]
Further, although the case where four disc springs 52 are used is shown, the number of disc springs 52 can be arbitrarily determined according to the allowable support force of the disc spring 52 without being limited to this number. At this time, the spring member is not limited to the disc spring 52, and any type of spring, for example, a coil spring or a leaf spring, can be used as long as the constant load region R is provided.
[0023]
Furthermore, although the case where the horizontal wheel 32 and the vertical wheel 34 were used as a horizontal direction control member and a vertical direction control member was shown, it replaces with these wheels, and it comprises also using a roller member etc. which used the sliding member and the bearing. be able to.

【The invention's effect】
As described above, in the opening / closing moving part structure of the opening / closing roof according to the present invention, the spring member having the constant load region is interposed in the displacement permissible gap provided in the horizontal direction regulating member. The horizontal force acting on the opposite side is absorbed by the deformation of the spring member, and the support point of the movable roof can be prevented from moving. In addition, this spring member has a spring characteristic of a constant load region, and this spring characteristic is interposed in the displacement allowance gap in a state where the load constant region is set, so that the horizontal force exerted on the fixed roof from the movable roof is constant. It is possible to prevent the relative position between the horizontal direction regulating member and the vertical direction regulating member and the fixed roof from changing. Therefore, even when the deformation of the movable roof and the member stress are applied as originally designed to reduce the weight of the roof part, the movable roof can be prevented from being detached and dropped, and can be opened and closed smoothly. .
