GATE OPENING/CLOSING MECHANISM
To provide an automatic gate opening/closing mechanism that does not invite an increase in a size but enables a gate to smoothly move at a time of automatic opening or closing.SOLUTION: A gate opening/closing mechanism includes a link part 3 capable of changing postures between a thrust posture (3T) of thrusting a lower end of a first arm 1 to outside of an outward facing surface A3 of a gate A, and a storage posture (3S) of positioning the lower end of the first arm 1 to immediately below or substantially immediately below a pivotal point R1 of the first arm 1 with respect to a bracket B, and a thrust posture sustaining part 6 that sustains the link part 3 in the thrust posture (3T). When the gate A is in a closed condition (A1), a second arm 2 is turned about a fixed axle RF1. Thus, the link part 3 is changed from the storage posture (3S) to the thrust posture (3T). After the link part 3 is changed from the storage posture (3S) to the thrust posture (3T), while the thrust posture (3T) is sustained by the thrust posture sustaining part 6, the gate A is changed from the closed condition (A1) to an open condition (A2).SELECTED DRAWING: Figure 4
【課題】サイズの大型化を招来することなく、自動開閉時にアオリが円滑に動作するアオリ自動開閉機構を提供する。【解決手段】第１アーム１の下端部をアオリＡの外向き面Ａ３よりも外側に持ち出す突っ張り姿勢（３Ｔ）と、第１アーム１の下端部をブラケットＢに対する第１アーム１の枢着点Ｒ１の真下または略真下に位置付ける収納姿勢（３Ｓ）との間で姿勢変更可能なリンク部３と、リンク部３を突っ張り姿勢（３Ｔ）に維持する突っ張り姿勢維持部６とを備え、アオリＡが閉状態（Ａ１）にある場合に第２アーム２を固定軸ＲＦ１周りに回動させることで、リンク部３を収納姿勢（３Ｓ）から突っ張り姿勢（３Ｔ）に切り替え、リンク部３が収納姿勢（３Ｓ）から突っ張り姿勢（３Ｔ）に切り替わった時点以降に突っ張り姿勢維持部６により突っ張り姿勢（３Ｔ）を維持したままアオリＡを閉状態（Ａ１）から開状態（Ａ２）に切り替えるようにした。【選択図】図４
