The restricting convex portion 11 is held in a non-rotatable manner to enable reliable locking.

次に、図９に基づいて、突出し窓用開閉装置１の操作手順について具体的に詳述する。図９は突出し窓２に装着した状態の突出し窓用開閉装置１の水平断面図である。   Next, based on FIG. 9, the operation procedure of the protruding window opening and closing apparatus 1 will be described in detail. FIG. 9 is a horizontal sectional view of the protruding window opening / closing device 1 in a state where it is mounted on the protruding window 2.

まず、図９(A)に示されるように、突出し障子４の開窓状態では、突出しアーム６を室外側方向にスライドさせ、前記アーム本体８のストッパー係止部１２ｃを台座５に係止させ、突出しアーム６がスライド不能に保持されている。このストッパー１２により、突出し障子４は安全に開窓状態が保持されるようになっている。この開窓状態から、摘み部８ａに備えられた押釦１２ｂを押圧してストッパー係止部１２ｃの係止を解除した後、突出しアーム６を室内側方向にスライドさせる。この突出しアーム６のスライド操作により、突出し障子４の閉窓が開始される。   First, as shown in FIG. 9 (A), when the protruding shoji 4 is in the open state, the protruding arm 6 is slid in the outdoor direction, and the stopper locking portion 12c of the arm body 8 is locked to the base 5. The protruding arm 6 is held non-slidable. The stopper 12 allows the protruding shoji 4 to be kept in an open window state safely. From this open state, the push button 12b provided on the knob 8a is pressed to release the stopper locking portion 12c, and then the protruding arm 6 is slid in the indoor direction. By the sliding operation of the protruding arm 6, the closing window of the protruding shoji 4 is started.

その後、図９(B)に示されるように、突出し障子４が完全に閉窓されると同時に、障子連結板９の室内側端部が貫通孔７内に形成された段差部２０に衝合する。これにより、前記障子連結板９は、室内側方向へのスライド及び回動が制限されるようになる。なお、この状態では、障子連結板９の係合突部１６が係合孔１７ｃに係合するとともに、アーム本体８の側面に施錠位置規制用凸部１１が存在しているため、アーム本体８の回動は制限されている。   Thereafter, as shown in FIG. 9B, the protruding shoji 4 is completely closed, and at the same time, the indoor side end portion of the shoji connecting plate 9 collides with the stepped portion 20 formed in the through hole 7. To do. As a result, the sliding plate connecting plate 9 is restricted from sliding and turning in the indoor direction. In this state, the engaging projection 16 of the shoji coupling plate 9 is engaged with the engaging hole 17c, and the locking position restricting convex portion 11 is present on the side surface of the arm main body 8. The rotation is limited.

次に、図９(C)に示されるように、前述の障子連結板９の室内側端部が貫通孔７内に形成された段差部２０に衝合した状態から、更に前記バネ材１９の付勢力に抗してアーム本体８を室内側へ引込み、前記障子連結板９の係合突部１６を係合孔１７ｃから解除するとともに、アーム本体８に形成された凹状溝１０の形成範囲に前記施錠位置規制用凸部１１を位置決めした状態にする。   Next, as shown in FIG. 9C, from the state in which the indoor side end portion of the aforementioned shoji coupling plate 9 abuts on the stepped portion 20 formed in the through hole 7, the spring material 19 is further moved. The arm body 8 is retracted indoors against the urging force to release the engagement protrusion 16 of the shoji coupling plate 9 from the engagement hole 17c, and within the formation range of the concave groove 10 formed in the arm body 8. The locked position restricting convex portion 11 is positioned.

これによって、アーム本体８は、図９(D)に示されるように、前記ピン部材１８を回動中心として施錠位置空間２１側へ回動可能な状態となる。   As a result, as shown in FIG. 9D, the arm body 8 is in a state of being able to rotate toward the locking position space 21 with the pin member 18 as the center of rotation.

その後、図９(E)に示されるように、凹状溝１０が施錠位置規制用凸部１１を乗り越えた段階でバネ材１９の付勢力によって自動的に台座５側に引き込まれ、前記アーム本体８の先端が嵌合凹部５ｃに嵌合するとともに、該アーム本体８が前記施錠位置規制用凸部１１によって回動不能に保持された施錠状態となる。   Thereafter, as shown in FIG. 9 (E), when the concave groove 10 gets over the locking position restricting convex portion 11, it is automatically pulled to the base 5 side by the biasing force of the spring material 19, and the arm body 8 The arm body 8 is in a locked state in which the distal end of the arm body 8 is non-rotatably held by the locking position restricting convex portion 11.

上述のように、突出し障子４の開窓状態と施錠状態との間の切り換えが、突出しアーム６のスライド及び回動の一連の操作によって可能となり、突出し障子４の開閉操作が簡便になる。さらに、施錠状態を解除するには、前記アーム本体８を自動的に引込まれた方向と逆側に引き出し、回動させる動作が必要となるため、容易に解錠されず確実な施錠が確保され、更に防犯効果の向上も図れる。   As described above, switching between the opened state and the locked state of the protruding shoji 4 can be performed by a series of operations of sliding and rotating the protruding arm 6, and the opening and closing operation of the protruding shoji 4 is simplified. Further, in order to release the locked state, the arm main body 8 needs to be pulled out to the opposite side of the automatically retracted direction and rotated, so that it is not easily unlocked and secure locking is ensured. Furthermore, the crime prevention effect can be improved.
