係合状態、すなわちクレセント部5のピン522aをスライド溝部711に係合した状態で内障子2を開放(左方向にスライド)すると、図7(a),(b)に示すように、ピン522aはスライド溝部711の幅広部711aからスライド部711bに移動するとともに、制限アーム7自体が支持軸613を中心にして回動する。
スライド溝部711のスライド部711bの幅寸法はピン522aのピン頭部522bの寸法よりも幅狭に形成されているので、ピン頭部522bがスライド溝部711から抜けることがなく、制限アーム7を回動させながらスムーズにスライドすることができる。
When the inner sash 2 is released (slid to the left) in the engaged state, that is, the state in which the pin 522a of the crescent part 5 is engaged with the slide groove part 711, as shown in FIGS. Moves from the wide portion 711a of the slide groove portion 711 to the slide portion 711b, and the limit arm 7 itself rotates about the support shaft 613.
Since the width of the slide portion 711b of the slide groove 711 is formed to be narrower than the size of the pin head 522b of the pin 522a, the pin head 522b does not fall out of the slide groove 711 and the restricting arm 7 is turned. It can slide smoothly while moving.
内障子2をさらに開放すると、図8(a),(b)に示すように、やがてピン522aがスライド部711bの先端部711cに当接し、それ以上のスライドを規制して開放を制限することができる。
ピン522aがスライド部711bの先端部711cに当接するときに、内障子2を開放しようとする力により制限アーム7には、図中左方向に引っ張る力が働き、この引っ張り力は制限アーム7を回動自在に支持している支持軸613を介して固定部材61に伝達されることになるが、固定部材61は右縦框34に形成された長ネジ孔341fの左端部にネジ止め固定されているので、それ以上の左(内周)方向への移動が規制され、引っ張り力によって固定部材61さらにはクレセント受け部6が左右方向にずれることが抑制される。
また、支持軸613に働く引っ張り力は、ネジ止め固定部bを中心とした時計回りの回転モーメントとして固定部材61に作用するが、固定部材61には、ネジ止め固定部bよりも上方位置において外障子3の右縦框34の係止片342cに内周側から当接する見込み片部612c及び右縦框34の内周壁341aに内周側から当接する肩部611bを備えているので、固定部材61の回転を抑制し、回転によるゆがみを防止することができる。
When the inner sash 2 is further opened, as shown in FIGS. 8A and 8B, the pin 522a eventually comes into contact with the tip 711c of the slide portion 711b, and further opening is restricted by restricting further slide. Can be.
When the pin 522a comes into contact with the distal end portion 711c of the slide portion 711b, a force pulling the restriction arm 7 to the left in the drawing acts on the restriction arm 7 due to the force for opening the inner sash 2 and the pulling force acts on the restriction arm 7. The power is transmitted to the fixing member 61 via the rotatable support shaft 613. The fixing member 61 is fixed to the left end of the long screw hole 341f formed in the right vertical frame 34 by screwing. Therefore, further movement in the left (inner circumferential) direction is restricted, and the displacement of the fixing member 61 and the crescent receiving portion 6 in the left-right direction due to the pulling force is suppressed.
Further, the pulling force acting on the support shaft 613 acts on the fixing member 61 as a clockwise rotation moment about the screw fixing portion b, but the fixing member 61 has a higher position than the screw fixing portion b. The outer sliding door 3 is provided with a prospective piece 612c that abuts on the locking piece 342c of the right vertical frame 34 from the inner peripheral side and a shoulder 611b that abuts on the inner peripheral wall 341a of the right vertical frame 34 from the inner peripheral side. The rotation of the member 61 can be suppressed, and distortion due to the rotation can be prevented.
一方、本実施形態の開放制限ストッパーAによる引き違い窓の開放制限を行わないときには、図6(b),(d)に示すように、クレセント部5に設けたピン522aを突出させることなく非係合位置に配置する。これにより、制限アーム7に形成されたスライド溝部711の幅広部711aに対してピン522aのピン頭部522が挿入することなく、クレセント受5と制限アーム7は、クレセント受5に制限アーム7が係合しない非係合状態となる。
クレセント受5と制限アーム7とが非係合状態となることによって、内、外障子2,3の開閉にかかわらず、図5(a)に示すように、制限アーム7は支持軸613から略垂直に支持されて回転規制片612dに当接もしくは近接した状態を維持することとなり、内、外障子2,3はなんら制限を受けることなく開放することができる。
このように、本実施形態の開放制限ストッパーAにおいては、クレセント受5と制限アーム7とを係合状態として引違い窓の開放制限を行う状態と、クレセント受5と制限アーム7とを非係合状態として引違い窓の開放制限を行わない状態とを選択することができる。
On the other hand, when the opening restriction of the sliding window is not performed by the opening restriction stopper A of the present embodiment, as shown in FIGS. 6B and 6D, the pin 522a provided on the crescent portion 5 is not protruded without being protruded. Place at the engagement position. As a result, the crescent receiver 5 and the limiting arm 7 can be connected to the crescent receiver 5 without the pin head 522 of the pin 522a being inserted into the wide portion 711a of the slide groove 711 formed in the limiting arm 7. It becomes a non-engagement state where it does not engage.
When the crescent receiver 5 and the restriction arm 7 are disengaged from each other, the restriction arm 7 is substantially disengaged from the support shaft 613 as shown in FIG. It is supported vertically and maintains a state of contacting or approaching the rotation restricting piece 612d, and the inner and outer sashes 2, 3 can be opened without any restrictions.
As described above, in the opening restriction stopper A of the present embodiment, the crescent receiver 5 and the restriction arm 7 are engaged to limit the opening of the sliding window, and the crescent receiver 5 and the restriction arm 7 are not engaged. A state in which the opening of the sliding window is not restricted can be selected as the combined state.
以上のように、本実施形態の開放制限ストッパーは、内外障子の開放を制限する制限アームが支持されるクレセント受け部の固定部材は、外障子の召合框の室内側壁に形成された長ネジ孔の左(内周側)端部においてネジ止め固定されるので、障子の開放時にかかるクレセント受けを引っ張る力に対して、長ネジ孔の左(内周側)端部で受けて対抗することができるので、固定部材61が内周方向(図中左方向)にずれることを抑制することができる。特に、長ネジ孔を上下二段に設けることにより、その抑制力は強くなるとともに、固定部材61の傾斜を抑制することができる。
そして、固定部材は、長ネジ孔の左(内周側)端部におけるネジ止め固定位置よりも上方位置において、召合框の係止片に内周側から当接する見込み片部や召合框の内周壁に内周側から当接する肩部を備えているので、固定部材の制限アームが引っ張られることによって、長ネジ孔の左端部を中心にして生じる時計回りの回転力に対して、見込み片部や肩部の当接により対抗することができるので、固定部材の回動を抑制し、クレセント受けが斜めにずれることを防止することができる。
このとき、固定部材の見込み片部は見込み幅を備えており、召合框の内周面に対して面で当接するので、召合框に対して確実に当接することができ、固定部材にかかる回転力を確実に規制することができる。
As described above, the opening restriction stopper of the present embodiment is such that the fixing member of the crescent receiving portion where the restriction arm for restricting the opening of the inner and outer sashes is supported is a long screw formed on the indoor side wall of the sumo frame of the outer sash. The left (inner circumference) end of the hole is screwed and fixed. Therefore, the left (inner circumference) end of the long screw hole should be used to counter the pulling force applied to the crescent receiver when the shoji is opened. Therefore, the displacement of the fixing member 61 in the inner circumferential direction (left direction in the drawing) can be suppressed. In particular, by providing the long screw holes in the upper and lower two stages, the suppressing force is increased and the inclination of the fixing member 61 can be suppressed.
The fixing member is located at a position above the screw fixing position at the left (inner peripheral side) end of the long screw hole. Is provided with a shoulder that abuts from the inner peripheral side to the inner peripheral wall of the fixing member, so that the clockwise rotation force generated around the left end of the long screw hole due to the pulling of the limit arm of the fixing member is expected. Since it can be countered by the contact of the one part and the shoulder part, the rotation of the fixing member can be suppressed, and the crescent receiver can be prevented from being obliquely shifted.
At this time, the prospective piece portion of the fixing member has a prospective width and comes into contact with the inner peripheral surface of the summing frame by a surface, so that it can reliably contact the summing frame, and Such a rotational force can be reliably regulated.
また、開放制限ストッパー、特にクレセント受け部を外障子の右縦框に取り付けるための構成を、従来周知のクレセント受けを取り付けるための構成と基本的に同じくすることができるので、縦框に特別な加工を施すことなく引違いサッシに開放制限ストッパーを備えたクレセント錠を装着することができる。
そして、開放制限ストッパーの固定部材の取付けは、固定部材をガラス間口に設けた切欠部から外周方向に挿入するだけで行うことができ、障子を分解することなく開放制限ストッパーの取付作業を容易に行うことができる。
In addition, since the configuration for attaching the opening restriction stopper, particularly the crescent receiving portion to the right vertical frame of the sash, can be basically the same as the configuration for mounting the conventionally known crescent receiving portion, a special configuration for the vertical frame is provided. A crescent lock provided with an opening restriction stopper can be attached to the pulling sash without processing.
The fixing of the fixing member of the opening restriction stopper can be performed only by inserting the fixing member in the outer peripheral direction from the notch provided in the glass frontage, and the mounting operation of the opening restriction stopper can be easily performed without disassembling the shoji. It can be carried out.
さらに、固定部材に制限アームを枢支した支持軸の下方外周側位置に、回動自在に支持された制限アームの外周側への回転を規制する回転規制片を備えているので、開放制限ストッパーにより開放制限を行わない場合などに、制限アームが無駄に回転して右縦框34に接触して衝突音の発生や傷付きなどを防止することができる。 Further, since a rotation restricting piece for restricting the rotation of the rotatably supported limiting arm toward the outer peripheral side is provided at a position on the outer peripheral side below the support shaft pivotally supporting the restricting arm on the fixing member, the opening restriction stopper is provided. Thus, when the opening restriction is not performed, the restriction arm can be prevented from rotating in vain and coming into contact with the right vertical frame 34 to prevent the generation of a collision sound or damage.
なお、本実施形態の開放制限ストッパーにおいては、固定部材は上下二段の長ネジ孔及びネジ孔を介して固定されているが、いずれか一方を固定するだけでも制限アームのずれを防止することができ、また、召合框に当接する当接部としては、当接部もしくは肩部のいずれか一方を設けるだけも良い。 In addition, in the opening restriction stopper of the present embodiment, the fixing member is fixed via the long screw hole and the screw hole of the upper and lower two steps, but it is possible to prevent the restriction arm from being displaced by fixing either one of them. In addition, it is only necessary to provide only one of the contact portion and the shoulder portion as the contact portion that contacts the summit frame.
