【０００７】
【発明の実施の形態】
以下、図面に示す実施の形態により、本発明を詳細に説明する。
【０００８】
図１ないし図７に示す本発明の第１の実施の形態において、１は目地部２を介して設けられた左右の建物３、３間の天井目地部２を覆う本発明の天井用目地カバー装置で、この天井用目地カバー装置１は前記左右の建物３、３の一方の建物３の目地部側の天井部の躯体３ａにヒンジ部材４を介してほぼ水平状態から先端部が上方向に回動可能に取付けられた前記目地部２を覆う目地カバー５と、この目地カバー５を地震等によって、前記目地部２が狭くなるように揺れ動いた場合に、目地カバー５を損傷することなく遊端部を上方へ回動させる、少なくとも１個以上、本発明の実施の形態では２個の目地カバー作動機構６、６と、前記目地カバー５の遊端部を覆うように前記他方の建物３の目地部側の躯体３ａの端部に固定されたカバー板７とで構成されている。
【０００９】
前記目地カバー５はアルミ、アルミ合金、ステンレス、ステンレス合金等の金属板の端部を、図４に示すようにほぼ直角に折り曲げた浅皿状に形成されたものが使用され、一側壁５ａに所定間隔で取付けられたヒンジ部材４によって、一方の建物３の目地部側の天井部の躯体３ａに取付けられるようになっている。
【００１０】
前記目地カバー作動機構６は、前記目地カバー５を取付けるヒンジ部材４の上部の天井部の躯体３ａに後端部が枢支金具８で枢支され、先端部が上方へ傾斜状態で配置される支持アーム９と、一端部が一方の建物３の目地部側の天井部の躯体３ａにスライド移動可能に当接し、他端部が他方の建物３の目地部側の天井部の躯体３ａにスライド移動可能に当接する、該他端部寄りの部位に前記支持アーム９の先端部が枢支ピン１０によって枢支された作動アーム１１と、この作動アーム１１の一方の建物３寄りの部位に一端部が取付けられ、他端部が前記目地カバー５の遊端部寄りの部位に取付けられたワイヤー、ロープ、鎖等の目地カバー支持紐１２と、前記目地カバー５の先端部が水平より下方へ下がるのを阻止できるように、前記支持アーム９の所定量以上の回動を阻止する、一端が支持アーム９のほぼ中央部寄りの部位に取付けられ、他端が一方の建物３の目地部側の天井部の躯体３ａに取付けられたワイヤー、ロープ、鎖等の回動阻止部材１３とで構成されている。
【００１１】
上記構成の天井用目地カバー装置１は通常時には図１に示すように、目地カバー５が目地カバー作動機構６、６によってほぼ水平状態で目地部２を覆う。
【００１２】
地震等によって目地部２が狭くなるように左右の建物３、３が揺れ動いた場合には、支持アーム９の先端部の枢支ピン１０を支点として作動アーム１１が、図５および図６に示すように回動する。
この時、支持アーム９の先端部の枢支ピン１０は作動アーム１１の他端部寄りの部位に取付けられているため、作動アーム１１の他端部の回動移動寸法に対し一端部の回動移動寸法が大きくなり、目地部が狭くなり、目地カバー５が左右の建物３、３の躯体３ａ、３ａに押しつぶされる前に、目地カバー５の遊端部を作動アーム１１の回動と、目地カバー支持紐１２とによって回動させ、収納することができる。
【００１３】
目地部２が広くなるように左右の建物３、３が揺れ動いた場合には、図７に示すように目地カバー５および目地カバー作動機構６、６は、目地カバー５が目地部２を覆っていた通常時の状態で他方の建物３の躯体３ａが離れていくだけで、その揺れ動きを吸収できる。
なお、地震等によって左右の建物３、３の目地部２が狭くなったり、広くなったりするような揺れ動きが停止した場合には、自動的に元の状態に戻る。
【００１４】
