【０００９】
【実施例】
本発明の実施例について添付図面を参照して説明する。
図１には、トイレットブースに設置された本発明にかかる指挟み防止装置付の開き戸が示されている。トイレットブースは間仕切Ｐで画成され、ブース前面には隣接壁パネル４に接して内開きの扉１が軸吊りによって設置されている。図中符号６は間仕切Ｐの連結部材を示す。また図中符号１０は後述する指挟み防止装置本体を示している。本発明にかかる指挟み防止装置は、防止装置本体１０と扉１の表面への止着手段とを具備する。
【００１０】
図２乃至図５には、本発明にかかる指挟み防止装置の第１実施例が示されている。開き戸において扉１は、所定の板厚を有し、その上下縁（図２および図３では下縁のみ示される。）において隣接壁パネル４の壁側縁５に近接した一側方に寄せた位置で軸受３ａに嵌合する吊り軸３に軸吊り支持されている。隣接壁パネル４の壁側縁５には扉側に面して横断面略凹円弧状外形を有する壁側縁部材７が固着されている。壁側縁部材７は隣接壁パネル４の端部を被覆保護し、壁側縁５の外形を形成している。吊り軸３に軸支された扉１の隣接壁パネル４に近接する側端縁２には隣接壁パネル４に面して横断面略凸円弧状外形を有する側縁材８が固着されている。側縁材８の両側には側方突縁９が扉１の表面側に突出しており、側縁材８は側端縁２をその一方の表面側から他方の表面側にかけて被覆保護すると共に、側端縁２の外形を形成している。扉１の閉鎖状態では、隣接壁パネル４の壁側縁部材７と扉１の側縁材８とは極めて接近した位置に対向して配置される。
【００１１】
金属または硬質合成樹脂製の指挟み防止装置本体１０は、扉１の表面にその底縁１１を接して所定高さ立上がる一対の平行板部１２ａよりなる立上部１２と、立上部１２の頂縁から扉１の軸吊り側の扉１の側端縁２に近接した扉１の表面にその先端縁１３が接する位置まで連設される曲面部１４とから形成される。この曲面部１４は、吊り軸３の軸心と軸吊り側の扉１の側端縁２との距離を略半径とする円弧状に形成されている。また先端縁１３には、扉１の側端縁２に取付けられる側縁材８の扉１の表面側に突出する側方突縁９に嵌合する嵌合凹縁１５が形成される。一対の平行板部１２ａ間における曲面部１４には装置本体１０の長さ方向に所定間隔をおいて止着螺子１７を挿通するための挿通孔１６が予めまたは装置本体１０設置時に穿設される。装置本体１０は扉１の開き方向側に止着されるが、扉１の表面に装置本体１０を止着するには、軸吊り側の扉１の側端縁２に曲面部１４の先端縁１３を近接して配置し、側縁材８の側方突縁９に曲面部１４の先端縁１３における嵌合凹縁１５を嵌合すると共に、立上部１２の底縁１１を扉１の表面に当接する。そして挿通孔１６から止着螺子１７を順次挿通して扉１に締付けることにより装置本体１０の止着を完了する。立上部１２を一対の平行板部１２ａで形成すると共に、一対の平行板部１２ａ間における曲面部１４に止着螺子１７を挿通するための挿通孔１６が穿設されるので、止着螺子１７の締付けによって、指挟み防止装置は変形することなく、安定した状態で扉１の表面に止着することが出来る。
【００１２】
このように装置本体１０が止着されると、装置本体１０の曲面部１４は扉１の断面略凸円弧状をなす側端縁２に連続して、吊り軸３の軸心と軸吊り側の側端縁２との距離を略半径とし、吊り軸３を中心とする円弧面を形成する。そして扉１は吊り軸３を中心に回転することから、図４に示される扉１の開放状態から、図５に示される扉１の閉鎖状態に至るまで、隣接壁パネル４の壁側縁５と、扉１の側端縁２または装置本体１０の曲面部１４との隙間は指の挿入が不可能な極めて狭い状態に維持されることになり、トイレットブース外Ｇからこの隙間に不用意に指を差込むことが防止され、指を挟む事故を未然に防止することが出来る。この指挟み防止装置は、扉の製造時に予め設置しておくことも可能であるが、前記したように、扉の上下縁の位置側方に寄せて軸吊りされると共に軸吊り側の扉の側端縁に横断面略凸円弧状外形を有する側縁材が取付けられている開き戸はトイレットブース等の建具として従来多用されており、指を挟む事故を起しやすいかかる既設の建具に対して、後から本発明にかかる指挟み防止装置を設置することが可能である。なおトイレットブース内側に開く扉１についてはこの例で説明したとおりであるが、トイレットブース外側に開く扉の場合には、装置本体１０を扉におけるトイレットブース外側の表面に止着して使用することができる。また両開きの扉に採用する場合には、装置本体１０を扉の両表面に止着して使用することが可能である。
【００１３】
図６乃至図１０には、本発明にかかる指挟み防止装置の第２実施例が示されている。扉１、側端縁２、吊り軸３、軸受３ａ、隣接壁パネル４、壁側縁５、壁側縁部材７、側縁材８、側方突縁９等は第１実施例と同様な構造を有している。金属または硬質合成樹脂製の指挟み防止装置本体１０は、扉１の表面に沿う外向きのＬ字状縁１８を底縁１１に連設して立上がる薄板状の立上部１２と、立上部１２の頂縁から扉１の軸吊り側の扉１の側端縁２に近接した扉１の表面にその先端縁１３が接する位置まで連設される曲面部１４とから形成される。この曲面部１４は、吊り軸３の軸心と軸吊り側の扉１の側端縁２との距離を略半径とする円弧状に形成されている。また先端縁１３には、扉１の側端縁２に取付けられる側縁材８の扉１の表面側に突出する側方突縁９に嵌合する嵌合凹縁１５が形成される。Ｌ字状縁１８裏面には、図８で明らかなように、接着層１９が設けられる。接着層１９は両面感圧接着シートを貼着したり、現場で接着剤を塗布したりして設けられる。装置本体１０は扉１の開き方向側に止着されるが、扉１の表面に装置本体１０を止着するには、軸吊り側の扉１の側端縁２に曲面部１４の先端縁１３を近接して配置し、側縁材８の側方突縁９に曲面部１４の先端縁１３における嵌合凹縁１５を嵌合する。そして立上部１２の底縁１１に連設するＬ字状縁１８を扉１の表面に当接して、Ｌ字状縁１８裏面の接着層１９を扉１の表面に対して接着させることにより止着を完了する。薄板状の立上部１２の底縁１１にＬ字状縁１８を連設し、Ｌ字状縁１８裏面に接着層１９を施す止着手段を採用することによって、指挟み防止装置を安価に製造できると共に、その止着作業も簡単に行うことが出来る。またＬ字状縁１８を螺子止して装置本体１０を止着することも可能である。
【００１４】
このように装置本体１０が止着されると、第１実施例と同様に、装置本体１０の曲面部１４は扉１の断面略凸円弧状をなす側端縁２に連続して、吊り軸３の軸心と軸吊り側の側端縁２との距離を略半径とし、吊り軸３を中心とする円弧面を形成する。そして扉１は吊り軸３を中心に回転することから、図９に示される扉１の開放状態から、図１０に示される扉１の閉鎖状態に至るまで、隣接壁パネル４の壁側縁５と、扉１の側端縁２または装置本体１０の曲面部１４との隙間は指の挿入が不可能な極めて狭い状態に維持されることになり、トイレットブース外Ｇからこの隙間に不用意に指を差込むことが防止され、指を挟む事故を未然に防止することが出来る。この指挟み防止装置は、扉の製造時に予め設置しておくことも可能であるが、前記したように、扉の上下縁の位置側方に寄せて軸吊りされると共に軸吊り側の扉の側端縁に横断面略凸円弧状外形を有する側縁材が取付けられている開き戸はトイレットブース等の建具として従来多用されており、指を挟む事故を起しやすいこのような既設の建具に対して、後から指挟み防止装置を設置することができる特徴がある。なおトイレットブース内側に開く扉１についてはこの例で説明したとおりであるが、トイレットブース外側に開く扉の場合には、装置本体１０を扉におけるトイレットブース外側の表面に止着して使用することができる。また両開きの扉に採用する場合には、装置本体１０を扉の両表面に止着して使用することが可能である。
【００１５】
【発明の効果】
本発明は、次のような効果を奏する。
Ａ．扉に止着された装置本体の曲面部は、扉の断面略凸円弧状をなす側端縁に連続して、吊り軸の軸心と軸吊り側の側端縁との距離を略半径とし、吊り軸を中心とする円弧面を形成するから、扉を回転した場合に、扉の開放状態から閉鎖状態に至るまで、隣接壁パネルの壁側縁と扉の側端縁または装置本体の曲面部との隙間は、指の挿入が不可能な極めて狭い状態に維持されることになり、トイレットブース外からこの隙間に不用意に指を差込んで指を挟む事故を未然に防止することが出来る。また曲面部の先端縁には、側縁材の扉表面側に突出する側方突縁に嵌合する嵌合凹縁が形成されているので、扉の側端縁に取付けられる側縁材と指挟み防止装置との接続箇所は凹凸なく円滑に接続される。
Ｂ．指挟み防止装置は、扉の製造時に予め設置しておくことも可能であるが、従来から扉の上下縁の位置側方に寄せて軸吊りされると共に軸吊り側の扉の側端縁に横断面略凸円弧状外形を有する側縁材が取付けられている開き戸は多用されており、指を挟む事故を起しやすいこのような既設の建具に対して、後から指挟み防止装置を設置することが可能である。
Ｃ．指挟み防止装置は、開き方向の扉の表面に設置して使用され、両開きの扉の場合には扉の両表面に設置して使用することが出来る。
Ｄ．立上部を一対の平行板部で形成すると共に、一対の平行板部間における曲面部に止着螺子を挿通するための挿通孔が穿設される態様では、止着螺子の締付けによって指挟み防止装置は変形することなく、安定した状態で扉の表面に止着することが出来る。
Ｅ．薄板状の立上部の底縁にＬ字状縁を連設し、Ｌ字状縁上から止着螺子を締付けたり、Ｌ字状縁裏面に接着層を施す止着手段を採用することによって、指挟み防止装置を安価に製造することができると共に、その止着作業も簡単に行うことが出来る。

A. The curved surface of the device main body fixed to the door is continuous with the side edge that has a substantially convex arc shape in the cross section of the door, and the distance between the axis of the suspension shaft and the side edge on the shaft suspension side is approximately the radius. Since the circular arc surface is formed around the suspension shaft, when the door is rotated, the wall side edge of the adjacent wall panel and the side edge of the door or the curved surface of the device main body from the open state of the door to the closed state The gap with the part will be maintained in a very narrow state where fingers cannot be inserted, and accidents that may cause accidents such as inadvertently inserting a finger into the gap from outside the toilet booth may be prevented. I can do it. Moreover, since the fitting edge which fits into the side protrusion which protrudes in the door surface side of a side edge material is formed in the front-end edge of a curved surface part, the side edge material attached to the side edge of a door and The connection point with the finger pinching prevention device is smoothly connected without unevenness.
B. The finger pinching prevention device can be installed in advance at the time of manufacturing the door, but conventionally it is suspended from the side of the upper and lower edges of the door and pivoted to the side edge of the door on the shaft suspension side. The hinged door to which the side edge material having a substantially convex arcuate cross-section is attached is often used, and a finger pinching prevention device is installed later on such existing fittings that are likely to cause a finger pinching accident. Is possible.
C. The finger pinching prevention device is used by being installed on the surface of the door in the opening direction, and in the case of a double-opening door, it can be installed and used on both surfaces of the door.
D. In a mode in which the upright portion is formed by a pair of parallel plate portions and an insertion hole for inserting the fixing screw is formed in the curved surface portion between the pair of parallel plate portions, finger clamping is prevented by tightening the fixing screw. The device can be secured to the door surface in a stable state without deformation.
E. By adopting a fastening means in which an L-shaped edge is connected to the bottom edge of the thin plate-like upright portion, a fastening screw is tightened from above the L-shaped edge, or an adhesive layer is applied to the back surface of the L-shaped edge, The finger pinching prevention device can be manufactured at low cost, and the fastening operation can be easily performed.
