Abstract

PURPOSE: To protect a sleeper against an accident in which he is trapped under a collapsed roof by routinely using an air film mat inflated up to the height of an upper surface inside a frame and releasing the air from the air film mat at the emergency time of an earthquake. CONSTITUTION: This protection bed consists of the flame 1 of a bed, an air film mat 2 and an exhaust device 3, and is useful for a comfortable sleep with the help of the air film mat 2 inflated to the height of an upper surface 1U in the frame 1. In addition, when an emergency case occurs that an earthquake of high magnitude which collapses the upstairs or roofs of a house or topples furniture such as shelves, hits, the air film mat 2 is contracted by releasing the air from the mat 2, using an exhaust device 3, then a sleeper is lowered into the frame 1 of the bed durably structured, through the center of the upper surface 1U, and is accommodated inside the frame 1. On the other hand, the upstairs or roofs of a house collapsed by the earthquake or the toppled furniture are supported by the frame 1. Thus the sleeper accommodated inside the frame 1 is prevented from becoming trapped under the debris by the protection bad.

【0008】
また、上記排気装置を、所定地震動の揺動で空気膜マットに衝突してその一部を破壊する開口具で形成し、家屋の上階や屋根が倒壊したり、家具が転倒するような大きな地震の所定地震動が襲ってきたときには、開口具が衝突して空気膜マットの一部を破壊し、その破壊部から空気膜マット内の空気を放出するように形成したものである。
【0009】
【作用】
この発明に係る防災ベッドは、睡眠者の横たわる上面の中央部を開口し、かつ床面から睡眠者を収容できる所定高さまで堅牢に組枠したベッドのフレームと、その開口したフレーム上面の高さまで空気を入れて膨らませた空気膜マットと、その空気膜マット内の空気を所定地震動が生じたときに放出する排気装置を設けているので、ベッド上を保護ケージのような覆うものがないため圧迫感がなく、保護ケージを設けたベッドのようにその設置に広い室内スペースを必要とせず、更にフレーム内側の上面高さまで膨らませた空気膜マットが快適な睡眠に役立つため、平常時にはベッド本来の目的に優れた機能を有し、大きな地震の所定地震動が襲ってきた非常時には、排気装置で空気膜マット内の空気を放出し、睡眠者を開口したフレーム上面中央部を通してフレーム内へ降ろし、収容した睡眠者より高い所定高さに上面を設けて堅牢に組枠したベッドのフレームが地震で倒壊した家屋の上階や屋根、或は転倒した家具を支えるため、睡眠者の下敷きを防げる。
【0010】
空気膜マットに設けた空気放出用のノズルと、そのノズルを閉塞する弁体と、その弁体を所定地震動の揺動で開動させる開動具からなる排気装置を形成した防災ベッドにおいては、弁体の開動具の調整によって、その開道具が作動する地震動の大きさをセットすることができるため、家屋の丈夫さや家具の設置状況に対応して開動具が作動する地震動の大きさを自由に選択してセットすることができるとともに、定期的な作動点検をすることができる。
【0011】
所定地震動の揺動で空気膜マットに衝突し、その一部を破壊する開口具で排気装置を形成した防災ベッドは、排気装置を簡単な構造で安価に形成できるため普及しやすい非常時用の構造に適したものである。
【0012】
【実施例】
本発明の実施例を図面に基づいて説明する。
図面中、1はベッドのフレームで、マットレス8や布団9等を用いて睡眠者10が横たわる上面1Uはその中央部を開口した長方形状とし、かつその上面1Uの下部に睡眠者10を収容できるるとともに這って移動できる高さの所定高さが確保できるように床11に向けて脚1Lを延出するとともに斜材1S等を取付けて形鋼や鋼管材等で堅牢に組枠して形成する。
【0013】
その上面1Uの中央部を開口したフレーム1の内部には、フレーム1の上面1U高さまで給気口12から空気を入れて膨らませた空気膜マット2を設け、その空気膜マット2の上に柔らかいマットレス8等を敷き、布団9や枕等を用いて睡眠者10が横たわれるように形成する。
【0014】
その空気膜マット2は、ナイロンやビニールの合成樹脂膜材等で気密状の袋体に形成し、その袋体には、空気を内部に入れるとともに入れた空気の流出を止める弁を設けた給気口12を取付け、図3及至図6にその構造例を示したような排気装置3を設け、家屋の上階や屋根が倒壊したり、家具の戸棚等が転倒するような大きな地震の所定地震動が襲ってきたときには空気膜マット2内の空気を放出するように形成する。
【0015】
叙述のようにベッドのフレーム1、空気膜マット2及び排気装置3を設けた防災ベッドは、ベッド上を保護ケージのような覆うものがないため圧迫感がなく、保護ケージを設けたベッドのようにその設置にひろい室内スペースを必要とせず、フレーム1内側の上面1U高さまで膨らませた空気膜マット2が快適な睡眠に役立つため、平常時にはベッド本来の目的に優れた機能を有する。
【0016】
また、この防災ベッドは、家屋の上階や屋根が倒壊したり、戸棚等の家具が転倒するような大きな地震の所定地震動が襲ってきた非常時には、空気膜マット2内の空気を排気装置3で放出して空気膜マット2を収縮させ、睡眠者10を開口した上面1Uの中央部を通して堅牢に組枠したベッドのフレーム1内へ降ろして収容するとともに、地震で倒壊した家屋の上階や屋根、或は転倒した家具は堅牢に組枠したベッドのフレーム1が支えるので、フレーム1内に収容された睡眠者10の下敷きが防げ、睡眠者10は地震動が収まってから安全に脚1L,1L間の脱出口13から脱出又は救出することができる。
【0017】
なお、空気を入れて膨らませる空気膜マット2は、水を入れて膨らませる水膜マットで形成して平常時の睡眠を快適にしても良いが、その際には、非常時の地震動が襲ってきたときに放出される水の排水対策が必要である。
【0018】

【0021】
このバネ体17の開道具6Bを設けた排気装置3Bは、大きな地震が襲ってきたときには、吊り紐19Bで吊り下げた重錘20が揺動して弁体5Bとノズル4Bの両鍔からストッパー18を引き抜き、コイル状のバネ体17が伸張して弁体5Bをノズル4Bから押し出して空気膜マット2内の空気を放出する構造としているので、その開道具6Bの作動は吊り紐19Bの長さや重錘20の大きさ、或は重さの調整等によって行え、家屋の丈夫さや家具の設置状況に対応して開道具6Bが作動する地震動の大きさをより適切に選定することができるとともに、定期的な作動点検を空気マット2を破壊することなく行うことができる。
【0022】
図5に弁体5Cの閉塞状況を実線、開動状況を破線で示した排気装置3Cは、空気膜マット2に設けた空気放出用の円筒状のノズル4Cと、そのノズル4Cを閉塞する合成ゴム材等で形成した円板逆止弁状の弁体5Cと、その弁体5Cを先端部で押して開動するとともにその弁体5Cの端部に鈎状の先端部が係合してその弁体5Cの開動を保持するような形状の弁棒21を上方の例えばベッドフレーム1から張りだしたサポート等に係合した吊り紐19Cで吊り下げて設けた開道具6Cで形成し、大きな地震が襲ってきたときには、吊り紐19Cで吊り下げた弁棒21が揺動してノズル4Cを閉塞している弁体5Cを開動するとともにその開動を保持し、空気膜マット2内の空気を放出するように形成する。
【0023】
このように弁棒21の開道具6Cを設けた排気装置3Cは、その開道具6Cの作動を吊り紐19Cの長さや弁棒21の大きさの調整によって行えるため、家屋の丈夫さや家具の設置状況に対応して開道具6Cが作動する地震動の大きさをより適切に選定することができ、定期的な作動点検を空気マット2を破壊することなく行うことができる。
【0024】
また、前述の開動具6A,6B,6Cを設けた排気装置3A,3B,3Cでは、空気膜マット2に設けた空気放出用のノズル4A,4B,4Cを大きくしたり、取付け個数を増やせば睡眠者10を短時間にベッドフレーム1内へ降下させることができ、ノズル4A,4B,4Cを小さくしたり、その取付け個数を減らせばゆっくり降下させることができるので、利用者に適した降下速度を選定することができる。よって、マットレス8との組合わせを勘案して、若年者の利用には衝撃が少し大きくても素早く降下させ、老年者の利用には降下作動の開始時期を早くしてゆっくり降下させるようにより適切な降下速度を選択し、選定するように形成する。
