OPENING RESTRICTION DEVICE FOR SLIDING SCREEN ROTATABLY OPENING/CLOSING
PROBLEM TO BE SOLVED: To enhance safety of a sliding screen by restricting for certain sudden opening of the sliding screen from a closed position due to wind pressure, and preventing the sliding screen from being pulled toward an outdoor side when releasing the opening restriction.SOLUTION: An opening restriction device for a sliding screen includes a stopping arm 10, a switching structure 11, and a stopper pin 12. The switching structure 11 switches the stopper pin 12 from a first engaging position to a second engaging position. An engaging groove 13 includes an entrance groove 24, a stopper groove 25, a switching groove 26, and an exit groove 27. A pin receiving wall 28 is provided at a groove end of the stopper groove 25 on the switching groove 26 side. When a sliding screen 2 is operated to be opened from a closed position, a contacting part 32 of the stopper pin 12 is received by the pin receiving wall 28, and kept at an opening restriction position. The stopper pin 12 is switched to the second engaging position by the switching structure 11 at the opening restriction position, to enable the contacting part 32 to pass through the switching groove 26 and the exit groove 27, and then the stopping arm 10 and the stopper pin 12 are disengaged.SELECTED DRAWING: Figure 1
【課題】障子が風圧を受けて閉じ位置から急開放するのを確実に規制でき、さらに開放規制状態を解除する際に室外側へ引っ張られるのを解消して、障子の安全性を向上する。【解決手段】ストップアーム１０と、切換え構造１１と、ストッパーピン１２を備えている。切換え構造１１は、ストッパーピン１２を第１係合位置から第２係合位置に切換える。係合溝１３は入口溝２４と、ストッパー溝２５と、切換え溝２６と、出口溝２７を備えている。ストッパー溝２５の切換え溝２６側の溝端にピン受壁２８を設ける。障子２を閉じ位置から開放操作するとき、ストッパーピン１２の接当部３２をピン受壁２８で受止めて開放規制位置に位置保持する。開放規制位置においてストッパーピン１２を切換え構造１１で第２係合位置に切換えて、接当部３２が切換え溝２６および出口溝２７を通過できるようにし、ストップアーム１０とストッパーピン１２の係合状態を解除する。【選択図】図１
