When the trigger 8 abuts on the front face of the door and recedes into the strike box in closing the door, the movable box 14 projects toward the front face of the door from an opening of a receiving member to fill the clearance. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、扉と扉枠の間の隙間(チリ)を自動的に調整するストライクに関するものである。  The present invention relates to a strike that automatically adjusts a gap (chile) between a door and a door frame.

蝶番で開閉する扉に用いられる扉錠は、扉2のフロント面4からラッチボルト又はデッドボルト等の錠杆6を突出させ、扉枠3の受部材9に係合させて施錠する。仮施錠用のラッチボルトはレバーハンドル7によって出没させ、本施錠用のデットボルトはシリンダー5又はサムターンを手動で回転させることによって出没させる。  A door lock used for a door that is opened and closed with a hinge is locked by causing a lock rod 6 such as a latch bolt or a dead bolt to protrude from the front surface 4 of the door 2 and engage with a receiving member 9 of the door frame 3. The latch bolt for temporary locking is raised and lowered by the lever handle 7, and the dead bolt for locking is raised and lowered by manually rotating the cylinder 5 or the thumb turn.

最近では、デッドボルトとラッチボルトを兼ねた一つの錠杆6を電気的に操作する電気錠も広く普及している。電気錠の錠杆6は完全に閉扉している状態でなければ突出しないようにする必要がある。開扉状態で錠杆6が突出していると、閉扉することができないからである。そのため、電気錠には、閉扉信号を認識する信号認識手段が施されているのが一般的である。
特開平08−093286
Recently, an electric lock that electrically operates one lock rod 6 serving both as a dead bolt and a latch bolt has become widespread. The lock 6 of the electric lock needs to be prevented from protruding unless it is completely closed. This is because the door cannot be closed if the lock 6 protrudes in the open state. Therefore, the electric lock is generally provided with signal recognition means for recognizing the closing signal.
JP 08-093286

しかし、いくら完全に閉扉していても、チリが大きすぎる場合には信号認識手段が閉扉信号を認識することができない。  However, no matter how completely the door is closed, if the dust is too large, the signal recognition means cannot recognize the door closing signal.

本発明は上記事情に鑑みてなされたもので、ある程度のチリが生じていても、信号認識手段が閉扉信号を認識することができるようにすることを課題とする。  This invention is made | formed in view of the said situation, and makes it a subject to enable a signal recognition means to recognize a closing signal, even if a certain amount of dust has arisen.

上記課題を解決するため、扉2の扉枠3に取り付けられる受部材9において、扉2を閉める際に扉2のフロント面4に当たると、トロヨケ12の内部に案内されながら後退動するトリガー8と、斜め状に刳り貫かれた複数の長穴19を有するスライド板18と、トリガー8の出没運動をスライド板18の往復運動に変換するダルマ15、17と、スライド板19の長穴20に係合する複数の突起21を有する可動ボックス14と、可動ボックス14等を収納するトロヨケ12を設けることにより、トリガー8が後退動すると受部材9の開口部11から可動ボックス14が扉2のフロント面4に向かってせり出してくるようにしたことを特徴とする自動チリ調整ストライク1を発明した。  In order to solve the above-described problem, in the receiving member 9 attached to the door frame 3 of the door 2, when the door 2 is closed, when it hits the front surface 4 of the door 2, the trigger 8 moves backward while being guided inside the troyoke 12 In addition, the slide plate 18 having a plurality of elongated holes 19 pierced diagonally, the dullers 15 and 17 for converting the movement of the trigger 8 into the reciprocating motion of the slide plate 18, and the elongated holes 20 of the slide plate 19 are related. By providing the movable box 14 having a plurality of projections 21 to be combined and the trowel 12 that accommodates the movable box 14 and the like, the movable box 14 is moved from the opening 11 of the receiving member 9 to the front surface of the door 2 when the trigger 8 moves backward. The invention has invented an automatic chile adjustment strike 1 characterized by projecting toward 4.

扉2と扉枠3の間に隙間(チリ)が生じていても、トリガー8が押されることによって可動ボックス14が突出し、そのチリが埋まり、あるいはチリが極力小さくなる。その結果、可動ボックス14に埋設されたマグネット13が電気錠側に限りなく接近し、電気錠の閉扉信号認識手段が閉扉信号を確実に認識できるようになる。  Even if there is a gap (chilli) between the door 2 and the door frame 3, when the trigger 8 is pushed, the movable box 14 protrudes and the dust is buried or the dust becomes as small as possible. As a result, the magnet 13 embedded in the movable box 14 approaches the electric lock as much as possible, and the electric lock closing signal recognition means can reliably recognize the closing signal.

図2に示すように、本発明に係る自動チリ調整ストライク1は、一般住宅やオフィスの玄関扉のように蝶番等で開閉する扉2の扉枠3に取り付けられる。  As shown in FIG. 2, the automatic chile adjustment strike 1 according to the present invention is attached to a door frame 3 of a door 2 that opens and closes with a hinge or the like like an entrance door of a general house or office.

本発明に係る自動チリ調整ストライク1は、手動で施解錠操作を行う一般扉錠との組み合わせにおいて用いることもできるが、電気的に施解錠を行う電気錠との組み合わせにおいて用いるのがベストである。閉扉したときに扉2と扉枠3の間に生じる隙間(チリ)を埋め、あるいは極力小さくし、電気錠が閉扉信号を認識できるようにすることを最大の目的としているからである。  The automatic chile adjusting strike 1 according to the present invention can be used in combination with a general door lock that manually performs locking and unlocking operations, but is best used in combination with an electric lock that performs electrical locking and unlocking. . This is because the main purpose is to fill a gap (chile) generated between the door 2 and the door frame 3 when the door is closed or to make it as small as possible so that the electric lock can recognize the closing signal.

図1に示すように、本発明に係る自動チリ調整ストライク1を構成する受部材9には、トリガー8が貫通する穴10と、可動ボックス14が貫通するために大きく開口した開口部11が存在する。  As shown in FIG. 1, the receiving member 9 constituting the automatic chile adjustment strike 1 according to the present invention has a hole 10 through which the trigger 8 passes and an opening 11 that is wide open for the movable box 14 to pass through. To do.

図3から図6に示すように、受部材9の後方には、箱型のトロヨケ12が、扉枠3に埋設されるように取り付けられるが、この中には、トリガー8、ダルマA15、ダルマB17、可動ボックス14、スライド板19その他の部品が収納される。  As shown in FIGS. 3 to 6, a box-shaped troyoke 12 is attached to the rear of the receiving member 9 so as to be embedded in the door frame 3, and includes a trigger 8, a Dharma A 15, a Dharma. B17, movable box 14, slide plate 19 and other components are stored.

図3及び図4に示すように、扉2が完全に閉まり、扉2のフロント面4によってトリガー8が押されると、トリガー8と係合しているダルマAの突片16が下方に押されるため、ダルマA15が反時計回りに回転し、これと一体的にダルマB17が反時計回りに回転する。  As shown in FIGS. 3 and 4, when the door 2 is completely closed and the trigger 8 is pushed by the front surface 4 of the door 2, the protrusion 16 of Dharma A engaged with the trigger 8 is pushed downward. Therefore, Dharma A15 rotates counterclockwise, and Dharma B17 rotates counterclockwise integrally therewith.

ダルマA15、ダルマB17が反時計回りに回転すると、ダルマBの突片18がスライド板19の切欠b部23に当たり、これがダルマBの突片18に押されてスライド板19が右にスライドする。  When the dharma A15 and the dharma B17 rotate counterclockwise, the projecting piece 18 of the dharma B hits the notch b portion 23 of the slide plate 19, which is pushed by the projecting piece 18 of the dharma B, and the slide plate 19 slides to the right.

トリガー8は、図示しないバネによって突出する方向に付勢されていることから、開扉されて扉2のフロント面4がトリガー8から離れると、トリガー8はフロント面の穴10から突出し、これに伴い、ダルマA15、ダルマB17が時計回りに回転する。  Since the trigger 8 is urged in a protruding direction by a spring (not shown), when the door is opened and the front surface 4 of the door 2 is separated from the trigger 8, the trigger 8 protrudes from the hole 10 on the front surface. Along with this, Dharma A15 and Dharma B17 rotate clockwise.

ダルマA15、ダルマB17が時計回りに回転すると、ダルマBの突片18がスライド板19の切欠a部22に当たり、これがダルマBの突片18に押されてスライド板19が左にスライドする。  When Dharma A15 and Dharma B17 rotate clockwise, the protrusion 18 of Dharma B hits the notch a portion 22 of the slide plate 19, which is pushed by the protrusion 18 of Dharma B, and the slide plate 19 slides to the left.

図3から図6に示すように、スライド板19には、二つの長穴20が斜め状にくり貫かれており、この2つの長穴20には、図5及び図6に示すように、可動ボックス14の2つの突起21が係合している。  As shown in FIG. 3 to FIG. 6, the slide plate 19 has two long holes 20 obliquely cut therethrough. As shown in FIG. 5 and FIG. Two protrusions 21 of the movable box 14 are engaged.

スライド板19が右にスライドすると、長穴20と突起21の係合関係により、可動ボックス14が受部材9の開口部11から突出し、逆に、スライド板19が左にスライドすると、可動ボックス14が引っ込む。  When the slide plate 19 slides to the right, the movable box 14 protrudes from the opening 11 of the receiving member 9 due to the engagement relationship between the long hole 20 and the protrusion 21. Conversely, when the slide plate 19 slides to the left, the movable box 14 Retracts.

可動ボックス14が扉1のフロント面4に接触したときの摩擦を最小限にするために、図1に示すように、可動ボックス14の囲み壁の一部をなだらかな凸状にして、高さ約3mm程度の凸部24を設けた。その結果、可動ボックス14が扉2のフロント面4に密着することを防止できる。  In order to minimize friction when the movable box 14 comes into contact with the front surface 4 of the door 1, as shown in FIG. 1, a part of the surrounding wall of the movable box 14 has a gentle convex shape to increase the height. The convex part 24 of about 3 mm was provided. As a result, it is possible to prevent the movable box 14 from coming into close contact with the front surface 4 of the door 2.

自動チリ調整ストライク1において、トリガー8が押され、可動ボックス14が突出して扉2のフロント面4に接触すると、チリは0(ゼロ)になる。その時点で扉2も完全に閉扉していることが望ましい。
仮に、その時点で扉が完全に閉扉していない場合には、当然ながら完全に閉扉させなければならないが、トリガー8を押すと、尚更、可動ボックス14が受部材の開口部11からせり出してくるので、それ以上閉扉することができないということになってしまう。そのため、かかる状況下でも、完全に閉扉できるようにすることが望ましい。
そこで、図9に示すように、二つのダルマ15、17の間にコイルバネ25を仕掛けることによって、当該コイルバネ25の付勢力に抗しつつ、トリガー8と可動ボッス14を押し込むことができるようにした。
In the automatic dust adjustment strike 1, when the trigger 8 is pushed and the movable box 14 protrudes and contacts the front surface 4 of the door 2, the dust becomes 0 (zero). It is desirable that the door 2 is also completely closed at that time.
If the door is not completely closed at that time, of course, it must be completely closed. However, when the trigger 8 is pressed, the movable box 14 protrudes from the opening 11 of the receiving member. As a result, the door cannot be closed any further. Therefore, it is desirable that the door can be completely closed even under such a situation.
Therefore, as shown in FIG. 9, by placing a coil spring 25 between the two dharmas 15 and 17, the trigger 8 and the movable box 14 can be pushed in against the urging force of the coil spring 25. .
