短い案内溝７は、戸開時係止溝２８の戸先側溝壁２８ａと連続するように戸先側から戸尻側に向かって斜め上向きに直線的に設けてある。接続溝３０は、戸開時係止溝２８と短い案内溝７の中間位置から戸開時係止溝２８の戸尻側溝壁２８ｂと連続し戸尻側に水平にのびる水平部３０ａと、水平部３０ａと連続する円弧部３０ｂを有している。長い案内溝６は、接続溝３０の円弧部３０ｂと連続して戸尻側に傾斜して斜め上向きに、短い案内溝７よりも長く設けてある。
戸１を開けた状態では、図１に示すように、戸１側の軸５ｂは戸開時係止溝２８に係止しており、指はさみ防止ストッパー２は、連結板４でケース２０と連結されることで水平よりやや上向きに傾いた状態に維持されている。 As shown in FIG. 1, the rotation limiting mechanism 3 includes a connecting plate 4 that connects the door 1 and the finger pinch prevention stopper 2, and shafts 5a and 5b that attach the connecting plate 4 to the finger pinch prevention stopper 2 and the door 1, respectively. A long guide groove 6 and a short guide groove 7 that guide the shaft 5b on the door 1 side, a door opening locking groove 28 in which the shaft 5b on the door 1 side locks when the door 1 is open, and a door opening locking groove 28 that guides the shaft 5b on the door 1 side. It has a connecting groove 30 that connects the time locking groove 28 to the long guide groove 6.
The long guide groove 6, the short guide groove 7, the door opening locking groove 28, and the connection groove 30 are provided on the facing wall 24 of the case 20, and the connecting plate 4 is connected to the rotation axis (shaft 21) of the finger pinch prevention stopper 2. ) connects the case 20 and the finger pinch prevention stopper 2.
The short guide groove 7 is provided diagonally upward and linearly from the door end side to the door end side so as to be continuous with the door end side groove wall 28a of the door opening locking groove 28. The connecting groove 30 has a horizontal portion 30a that extends horizontally from the intermediate position between the door opening locking groove 28 and the short guide groove 7 to the door bottom side gutter wall 28b of the door opening locking groove 28 and extending horizontally toward the door bottom side. It has a circular arc portion 30b that is continuous with the portion 30a. The long guide groove 6 is continuous with the circular arc portion 30b of the connection groove 30, and is inclined obliquely upward toward the door end side and is longer than the short guide groove 7.
When the door 1 is open, as shown in FIG. 1, the shaft 5b on the door 1 side is locked in the door opening locking groove 28, and the finger pinch prevention stopper 2 is connected to the case 20 by the connecting plate 4. By connecting them, they are kept tilted slightly upwards from the horizontal.

戸先側の縦枠１１の内周側面には、指はさみ防止装置１９と対向する位置に受け部品２５が取付けてある。受け部品２５は、戸１を閉めたときに指はさみ防止ストッパー２の先端部の円弧状のコーナー部２３が当接する上向きの傾斜面２６を有している。 A receiving part 25 is attached to the inner peripheral side surface of the vertical frame 11 on the door edge side at a position facing the finger pinch prevention device 19. The receiving part 25 has an upwardly inclined surface 26 against which the arcuate corner part 23 at the tip of the finger pinch prevention stopper 2 comes into contact when the door 1 is closed.

図７は、戸１を通常の速度で閉めたとき、すなわち、引手１８を持った状態で普通に戸１を閉めたときで、指はさみのおそれがないときの指はさみ防止装置１９の動きを示している。
戸１を通常の速度で閉めると、図７（ａ）に示すように、指はさみ防止ストッパー２先端部のコーナー部２３が受け部品２５の傾斜面２６に当たって上向きに押されることで、指はさみ防止ストッパー２が上向きに回転する。
指はさみ防止ストッパー２の回転に伴い、連結板４の戸１側の軸５ｂが連結板４により戸尻側に押されることで、図７（ｂ）に示すように、連結板４の戸１側の軸５ｂが戸開時係止溝２８の戸尻側溝壁２８ｂに沿って接続溝３０の水平部３０ａに進入する。
その後、図７（ｃ）に示すように、指はさみ防止ストッパー２がさらに回転するにつれて連結板４の戸１側の軸５ｂが接続溝３０の円弧部３０ｂから長い案内溝６へと進入することで、指はさみ防止ストッパー２が回転してケース２０内に収納されるので、戸１を閉め切ることができる。その後、戸１を開けると指はさみ防止ストッパー２は自重で倒れ、図１の状態に戻る。 FIG. 7 shows the movement of the finger pinch prevention device 19 when the door 1 is closed at a normal speed, that is, when the door 1 is closed normally while holding the handle 18, and there is no risk of finger pinch. It shows.
When the door 1 is closed at a normal speed, the corner portion 23 at the tip of the finger pinch prevention stopper 2 hits the inclined surface 26 of the receiving part 25 and is pushed upward, as shown in FIG. 7(a), thereby preventing finger pinch. Stopper 2 rotates upward.
As the finger pinch prevention stopper 2 rotates, the shaft 5b of the connecting plate 4 on the door 1 side is pushed toward the door end side by the connecting plate 4, so that the door 1 of the connecting plate 4 is pushed as shown in FIG. 7(b). The side shaft 5b enters the horizontal portion 30a of the connecting groove 30 along the door end side groove wall 28b of the locking groove 28 when the door is opened.
Thereafter, as the finger pinch prevention stopper 2 further rotates, the shaft 5b of the connecting plate 4 on the door 1 side enters the long guide groove 6 from the circular arc portion 30b of the connecting groove 30, as shown in FIG. 7(c). Then, the finger pinch prevention stopper 2 is rotated and stored in the case 20, so that the door 1 can be completely closed. Thereafter, when the door 1 is opened, the finger pinch prevention stopper 2 collapses under its own weight and returns to the state shown in FIG. 1.

このように本建具は、戸１を通常の速度で閉めたときは、連結板４の戸１側の軸５ｂが長い案内溝６に進入することで指はさみ防止ストッパー２の回転を許容するので、戸１が閉まるにつれて指はさみ防止ストッパー２が自然に回転してケース２０に収納され、ストッパーを解除する特別な操作が不要なので、使い勝手が良い。 In this way, when the door 1 is closed at a normal speed, the shaft 5b of the connecting plate 4 on the door 1 side enters the long guide groove 6, allowing the finger pinch prevention stopper 2 to rotate. As the door 1 closes, the finger pinch prevention stopper 2 naturally rotates and is housed in the case 20, and there is no need for a special operation to release the stopper, making it easy to use.

一方、戸１を通常の速度より勢いよく閉めたとき、例えば、何らかの原因で引手１８が戸先側に強く押され、その反動で戸１が勢いよく閉まったような場合には、図２に示すように、指はさみ防止ストッパー２の先端部が縦枠１１の受け部品２５に衝突するのに伴い、連結板４の戸１側の軸５ｂが戸開時係止溝２８の戸先側溝壁２８ａに沿って瞬間的に上方に移動して短い案内溝７に進入することで（図中の矢印２７参照）、指はさみ防止ストッパー２の回転が制限されて突出した状態に維持され、指はさみ防止ストッパー２により縦枠１１と戸１との間に間隔２９が形成されるので、指はさみが防がれる。 On the other hand, when the door 1 is closed more forcefully than the normal speed, for example, the handle 18 is pushed strongly toward the door end for some reason, and the door 1 closes forcefully as a result of the reaction. As shown, as the tip of the finger pinch prevention stopper 2 collides with the receiving part 25 of the vertical frame 11, the shaft 5b of the connecting plate 4 on the door 1 side hits the door end side groove wall of the locking groove 28 when the door is opened. By momentarily moving upward along 28a and entering the short guide groove 7 (see arrow 27 in the figure), the rotation of the finger pinch prevention stopper 2 is restricted and maintained in the protruding state, and the finger pinch prevention stopper 2 is kept in a protruding state. Since the preventive stopper 2 forms a gap 29 between the vertical frame 11 and the door 1, finger pinching is prevented.

このように本建具は、戸１を通常の速度で閉めたときには、指はさみ防止ストッパー２が自動的に回転してケース２０内に収納されるので、特別な操作を行うことなく戸１を閉め切ることができ、戸１を通常の速度より勢いよく閉めたときには、指はさみ防止ストッパー２の回転が制限されて指はさみを防止することができ、使い勝手の良さと安全性を両立できる。 In this way, when the door 1 is closed at a normal speed, the finger pinch prevention stopper 2 automatically rotates and is stored in the case 20, so the door 1 can be closed without any special operation. When the door 1 is closed more forcefully than the normal speed, the rotation of the finger pinch prevention stopper 2 is restricted to prevent finger pinch, thereby achieving both ease of use and safety.

以上に述べたように本建具は、戸１と指はさみ防止ストッパー２と回転制限機構３とを備え、指はさみ防止ストッパー２は、回転により戸１の戸先より出没自在であり、戸１を開けたときに戸１の戸先より突出するものであり、回転制限機構３は、戸１と指はさみ防止ストッパー２とをつなぐ連結板４と、連結板４を指はさみ防止ストッパー２と戸１にそれぞれ取り付ける軸５ａ，５ｂと、戸１側の軸５ｂを案内する長い案内溝６と短い案内溝７とを有し、戸１を通常の速度で閉めたときは戸１側の軸５ｂが長い案内溝６に進入することで指はさみ防止ストッパー２が回転して戸１内に没入するため、特別な操作を行うことなく戸１を閉め切ることができ、戸１を通常の速度より勢いよく閉めたときには戸１側の軸５ｂが短い案内溝７に進入することで指はさみ防止ストッパー２の回転を制限して突出した状態に維持するので、指はさみを防止することができる。
また本建具は、戸１に取付けたケース２０を有し、ケース２０に指はさみ防止ストッパー２が突没自在に軸支してあり、戸１側の軸５ｂは連結板４とケース２０との間に設けてあり、ケース２０の見付壁２４に長い案内溝６と短い案内溝７とが設けてあるので、指挟み防止ストッパー２をケース２０ごと戸１に取付ければよく、指挟み防止ストッパー２を戸１に容易に取付けできる。また、既存の戸１に後から指はさみ防止ストッパー２を取付けるのも容易である。
本建具は、ストッパーを解除するための操作部が不要であり、戸１の見付面に指はさみ防止装置１９の部品が露出しないので、意匠性も良い。 As described above, this fitting includes a door 1, a finger pinch prevention stopper 2, and a rotation restriction mechanism 3, and the finger pinch prevention stopper 2 can freely come out and go from the door end of the door 1 by rotation. The rotation limiting mechanism 3 protrudes from the tip of the door 1 when opened, and the rotation limiting mechanism 3 includes a connecting plate 4 that connects the door 1 and the finger pinch prevention stopper 2, and a connecting plate 4 that connects the finger pinch prevention stopper 2 and the door 1. It has a long guide groove 6 and a short guide groove 7 that guide the shaft 5b on the door 1 side, and when the door 1 is closed at a normal speed, the shaft 5b on the door 1 side is By entering the long guide groove 6, the finger pinch prevention stopper 2 rotates and enters the door 1, so the door 1 can be completely closed without any special operation, and the door 1 can be moved faster than the normal speed. When the door 1 is properly closed, the shaft 5b on the door 1 side enters the short guide groove 7 to restrict the rotation of the finger pinch prevention stopper 2 and maintain it in a protruding state, so that finger pinch can be prevented.
In addition, this fixture has a case 20 attached to the door 1, and a finger pinch prevention stopper 2 is pivotably supported on the case 20 so as to be freely projectable and retractable. Since a long guide groove 6 and a short guide groove 7 are provided in the facing wall 24 of the case 20, it is only necessary to attach the finger pinch prevention stopper 2 to the door 1 along with the case 20, and the finger pinch prevention stopper 2 can be attached to the door 1 together with the case 20. The stopper 2 can be easily attached to the door 1. Further, it is easy to attach the finger pinch prevention stopper 2 to the existing door 1 later.
This fixture does not require an operating part to release the stopper, and the parts of the finger pinch prevention device 19 are not exposed on the facing surface of the door 1, so the design is good.

本発明は以上に述べた実施形態に限定されない。指挟み防止ストッパーや連結板の形状や材質、長い案内溝と短い案内溝の形状等は、適宜変更することができる。戸の構造は問わない。指挟み防止ストッパーは、実施形態のように自重で倒れるものの他、バネの付勢力で倒れるものであってもよい。本発明は、浴室戸に限らず、引戸を備えるあらゆる建具に適用することができる。 The invention is not limited to the embodiments described above. The shape and material of the finger pinch prevention stopper and the connecting plate, the shapes of the long guide groove and the short guide groove, etc. can be changed as appropriate. The structure of the door does not matter. The finger pinch prevention stopper may fall down by its own weight as in the embodiment, or may fall down by the urging force of a spring.
