LOCK RELEASE DEVICE OF FITTING AND ENGAGING-DISENGAGING DEVICE OF FITTING
To execute a lock release of a small opening member and handle operation for closing a sash by one-hand.SOLUTION: A sash guides opening-closing of the sash by inserting a regulation pin 43 into an opening-closing cam groove 45 formed in a small opening regulation arm 42 for opening up to predetermined opening from a closing position. The small opening regulation arm 42 is locked by locking the regulation pin 43 on the innermost part of a tail end groove part 45b of the opening-closing cam groove 45 in a small opening position of the sash. When downwardly operating an operation lever 50b provided on a depth surface in an opening groove, an operation member 48 projects via a release plate 50, and pushes and rotates a lower end part of the small opening regulation arm 42. The regulation pin 43 is disconnected from the innermost part of the opening-closing cam groove 45 by rotation of the small opening regulation arm 42, and releases a lock. An opening position of a handle 30 for operating the sash for opening-closing and the operation lever 50b exist in a proximal position, and can be operated by one-hand.SELECTED DRAWING: Figure 5
【課題】片手で小開口部材のロック解除と障子の閉鎖のためのハンドル操作とを行える。【解決手段】障子が閉鎖位置から所定開度まで開かせる小開口規制アーム４２に形成された開閉カム溝４５に規制ピン４３を挿入させて障子の開閉をガイドする。小開口規制アーム４２は障子の小開口位置で開閉カム溝４５の終端溝部４５ｂの最奥部に規制ピン４３が係止してロックする。見込み面に設けた操作レバー５０ｂを開口溝内で下方に操作すると、解除プレート５０を介して作動部材４８が突出して小開口規制アーム４２の下端部を押して回動させる。小開口規制アーム４２の回動で規制ピン４３が開閉カム溝４５の最奥部から外れてロックを解除する。障子を開閉作動するハンドル３０の開放位置と操作レバー５０ｂは近接する位置にあり、片手で操作できる。【選択図】図５
