Description

本発明は、扉錠の施錠片（例えばデッドボルト）が嵌入した場合に於いて、扉錠の施・解錠状態の信号を取得するためのスイッチ部材をトロヨケ内に備えたドア用錠受け金具に関し、例えば地震時に適合するドア用錠受け金具に関する。 The present invention relates to a door lock receiving bracket provided with a switch member in a troyoke for acquiring a signal of the lock / unlock state of the door lock when a locking piece (for example, a dead bolt) of the door lock is inserted. For example, the present invention relates to a lock bracket for a door that is adapted in the event of an earthquake.

特許文献1には、受け金具を構成するトロヨケ内にドアースイッチ作動装置を配設する事項が記載されている。受け金具は、普通一般にサッシ型ドア枠内に嵌め込まれるケース状のトロヨケと、該トロヨケの前端開口部に設けられるプレート状のストライクとから成るが、前記ドアースイッチ作動装置は、前端開口部からトロヨケ内に組み込まれる。例えば、可動接触片（可動板）を有するマイクロスイッチは、トロヨケの内壁面に適宜に固定され、前記可動板は閉扉時に錠前のデッド（ボルト）がストライクを介してトロヨケ内に嵌入すると、ボルトの先端面により押圧されて回転する。 Patent Document 1 describes a matter of disposing a door switch operating device in a trolley that constitutes a receiving metal fitting. The bracket is generally composed of a case-like troyoke fitted into a sash-type door frame and a plate-like strike provided at the front end opening of the troyoke. The door switch operating device is connected to the troyoke from the front end opening. Embedded in. For example, a micro switch having a movable contact piece (movable plate) is appropriately fixed to the inner wall surface of the troyoke, and when the dead plate (bolt) of the lock is inserted into the troyoke through a strike when the movable plate is closed, It is pressed by the tip surface and rotates.

可動板がボルトの押圧力により付勢バネのバネ力に抗してトロヨケの奥の後壁側へ回転すると、可動板に連動するカムを介してスイッチが切換えられる。このスイッチの切換信号用の配線は、トロヨケの側壁又は後壁に形成された貫通孔を介してトロヨケの外に導き出される。 When the movable plate rotates against the spring force of the biasing spring due to the pressing force of the bolt, the switch is switched via a cam linked to the movable plate. The switch switching signal wiring is led out of the troyoke through a through hole formed in the side wall or the rear wall of the troyoke.

また、特許文献2には、戸先が戸枠に衝突した際に、該閉扉信号を取得するためのスイッチのオン・オフ機構をトロヨケの内部に配設する事項が記載されている。しかし、この特許文献2のスイッチも特許文献1と同様に前端開口部からトロヨケ内に組み込むものである。 Patent Document 2 describes a matter in which an on / off mechanism for a switch for obtaining the door closing signal is disposed inside the troyoke when the door collides with the door frame. However, the switch of Patent Document 2 is also incorporated into the trolley from the front end opening as in Patent Document 1.

ところで、錠前の施錠信号を収得するためのマイクロスイッチは、特許文献1や特許文献２のようにケース状のトロヨケの前端開口から支持片、固着具等を介して取付けることから、その取付けや部品交換が非常に面倒であるという問題がある。 By the way, the microswitch for acquiring the lock signal of the lock is mounted from the front end opening of the case-shaped troyoke via a support piece, a fixing tool, etc. There is a problem that the exchange is very troublesome.

また、地震発生時、可動ストライクがトロヨケの後方空隙部へと後退動可能なドア用錠受け金具に於いて、トロヨケの内部にスイッチ機構を配設する場合、該スイッチ機構を構成するマイクロスイッチ、支持片、固着具等がトロヨケの内部を占有することにより、可動ストライクの後退動を妨げる障害部材にならないように取付け工夫をすることが望まれる。
実公昭４８−５６５５号公報特許公開２００５−９１７５号公報特開２００４−３６２７０号公報特開平１１−６２３３７号公報 In addition, in the case of a door lock bracket that allows a movable strike to move backward to the rear gap of the troyoke when an earthquake occurs, when a switch mechanism is disposed inside the troyoke, a micro switch that constitutes the switch mechanism, It is desired to devise the mounting so that the support piece, the fixing tool, etc. occupy the inside of the troyoke so that it does not become an obstacle member that prevents the movable strike from moving backward.

以下、図１ないし図８を参照にして第１実施例を説明する。 Hereinafter, the first embodiment will be described with reference to FIGS.

（１）本発明の基本的構成
本発明は、トロヨケ内にスイッチ部材を備えたドア用錠受け金具の構造に特徴がある。付言すると、本発明のドア用錠受け金具Ｘは、図２及び図３で示すように、切欠状の開口部１５ｃを有するトロヨケ２と、該トロヨケ２のケース部１５の後壁（底部）の外壁面に前記開口部１５ｃを塞ぐように添設状態に固定され、かつ、スイッチ部材１９を備えた取付けベース板１８とから成る点に特徴がある。 (1) Basic configuration of the present invention The present invention is characterized by the structure of a door lock receiving metal fitting provided with a switch member in a trolley. In addition, as shown in FIG. 2 and FIG. 3, the door lock bracket X of the present invention includes a troyoke 2 having a notch-shaped opening 15 c and a rear wall (bottom part) of the case part 15 of the troyoke 2. The mounting base plate 18 is fixed to the outer wall surface so as to close the opening 15c and includes the switch member 19.

（２）本発明の実施の環境部材
まず、図１を参照にして、本発明の実施の環境部材を説明する。１はサッシ型のドア枠、２はドア枠に嵌合状態に固定されるトロヨケ、３はトロヨケの奥の内壁面並びに上下の対向内壁等との間にそれぞれ空隙部３０，３１を設定して遊嵌合状態に嵌め込まれる枠状可動コア、４はこの可動コア３の前面に一体的に設けられ、かつ、トロヨケ２から常時突出する可動ストライク、一方、５はトロヨケ２の前面に一体的に設けられ、かつ、縦長状の開口部６を有するカバープレートである。 (2) Environmental Member for Implementing the Present Invention First, an environmental member for implementing the present invention will be described with reference to FIG. 1 is a sash-type door frame, 2 is a troyoke fixed to the door frame in a fitted state, 3 is a space 30 and 31 between the inner wall at the back of the troyoke and the upper and lower opposing inner walls, respectively. A frame-shaped movable core 4 to be fitted in the loosely fitted state is integrally provided on the front surface of the movable core 3 and is a movable strike that always protrudes from the troyoke 2, while 5 is integrally formed on the front surface of the troyoke 2. The cover plate is provided and has a vertically long opening 6.

カバープレート５は、開口部６を形成する縦方向の一辺（縦縁部）に切欠部６ａを有していることから、開口部６から常時突出する可動ストライク４は、地震発生時、可動コア３の後退動を介してカバープレート５と面一の状態になる位置まで後退可能である。なお、Ｄはドア枠１に対して開閉可能に設けられるドア、ａはドア側に設けた錠前の施錠片（ここではデッドボルト）である。 Since the cover plate 5 has a notch 6a on one side (vertical edge) in the vertical direction forming the opening 6, the movable strike 4 that always protrudes from the opening 6 has a movable core when an earthquake occurs. 3 can be moved back to the position where the cover plate 5 is flush with the cover plate 5. Note that D is a door that can be opened and closed with respect to the door frame 1, and a is a lock piece (here, a dead bolt) provided on the door side.

図１は、サッシ型ドア枠１にトロヨケ２に合わせたカバープレート５の開口部６から可動ストライク４が突出した状態で枠状可動コア３をトロヨケ２内に組込み込んでいる状態を示す。しかも、該可動コア３は、少なくとも上下一対の保持板８，８を介してトロヨケ２内にセットされている通常の使用状態を示す。また、トロヨケ２とカバープレート５は固着具を介してドア枠１に固定されている。 FIG. 1 shows a state in which the frame-shaped movable core 3 is incorporated in the troyoke 2 with the movable strike 4 protruding from the opening 6 of the cover plate 5 aligned with the troyoke 2 on the sash-type door frame 1. In addition, the movable core 3 exhibits a normal use state in which it is set in the trolley 2 via at least a pair of upper and lower holding plates 8 and 8. Moreover, the trowel 2 and the cover plate 5 are being fixed to the door frame 1 through the fixing tool.

図２を参照にして錠受け具Ｘの構成部材を順番に説明する。なお、角筒部状のドア枠１の詳細は割愛する。 The constituent members of the lock receiver X will be described in order with reference to FIG. The details of the rectangular tube-shaped door frame 1 are omitted.

（３）錠受け具の構成部材−トロヨケ２
次に、図２、図３等も参照にして、トロヨケ２について説明する。例えば図２、図３で示すように、トロヨケ２の形状は普通一般のそれと同様である。すなわち、トロヨケ２の部分を区分けすると、ドア枠１にスッポリトと入り込む正面開口のケース部１５と、このケース部１５の開口１６側の上下端部にそれぞれ一体形成された突片状の取付け片１７，１７とから成り、前記取付け片１７，１７には、ドア枠１のネジ孔と符合する不番の貫通孔が形成されている。 (3) Constituent member of lock holder-Troyoke 2
Next, Troyoke 2 will be described with reference to FIGS. For example, as shown in FIGS. 2 and 3, the shape of Troyoke 2 is generally the same as that of a general one. That is, when the portion of the trolley 2 is divided, a case portion 15 having a front opening that enters the door frame 1 and a projecting piece-like mounting piece 17 integrally formed on the upper and lower ends of the case portion 15 on the opening 16 side, respectively. , 17, and the mounting pieces 17, 17 are formed with unnumbered through holes that match the screw holes of the door frame 1.

しかして、前記ケース部１５の左右の側壁１５ａと直交する奥の後壁１５ｂの中央部から下部に至るまで、縦長の切欠状開口（後方開口）１５ｃが形成されている。この切欠状開口１５ｃの縦方向の長さ及び幅寸法は、取付けベース板１８に取付けられたスイッチ部材１９の構成・形状・位置をそれぞれ考慮して適宜に設定される。 Thus, a vertically long notch-shaped opening (rear opening) 15c is formed from the center to the lower part of the rear wall 15b that is perpendicular to the left and right side walls 15a of the case part 15. The length and width dimension of the notch-shaped opening 15c in the vertical direction are appropriately set in consideration of the configuration, shape, and position of the switch member 19 attached to the attachment base plate 18.

前述したように、本発明のドア用錠受け金具Ｘは、切欠状の開口部１５ｃを有するトロヨケ２と、スイッチ部材１９が前記後方開口１５ｃを介してトロヨケ２の内部空間に位置するようにトロヨケ２のケース部１５に添設状態に固定される取付けベース板１８から成る。 As described above, the door lock bracket X according to the present invention has the troyoke 2 having the notch-shaped opening 15c and the joystick so that the switch member 19 is located in the inner space of the troyoke 2 through the rear opening 15c. It consists of a mounting base plate 18 fixed to the two case portions 15 in an attached state.

すなわち、図３で示すように、トロヨケ２の奥の後壁１５ｂに切欠状の開口部１５ｃが形成され、一方、トロヨケ２とは別体の取付けベース板１８の一側面に予め錠前の施錠状態の信号を得るためのスイッチ部材１９が固定され、該スイッチ部材１９は、前記取付けベース板１８をトロヨケ２の奥の後壁１５ｂの外壁面に複数本の固着具１０を介して固定すると、切欠状の開口部１５ｃに位置付けられる（図１参照）。つまり、スイッチ部材１９は、トロヨケ２の奥の空間部分に配設される。 That is, as shown in FIG. 3, a notch-shaped opening 15 c is formed in the rear wall 15 b of the back of the troyoke 2, and on the other hand, a locked state in advance on the one side of the mounting base plate 18 separate from the troyoke 2 The switch member 19 for obtaining the signal is fixed, and when the mounting base plate 18 is fixed to the outer wall surface of the rear wall 15b in the back of the trolley 2 via a plurality of fixing tools 10, It is located in the shape-like opening part 15c (refer FIG. 1). In other words, the switch member 19 is disposed in the space portion behind the trolley 2.

ここで、図２のスイッチ部材１９の拡大図を参照にして、スイッチ部材１９の構成を簡単に説明する。１１は端面Ｚ型形状の内装支持片で、該内装支持片１１は取付けベース板１８の外側（逆側）から固着具１２を介して取り外し可能に固定されている。 Here, with reference to the enlarged view of the switch member 19 of FIG. 2, the structure of the switch member 19 is demonstrated easily. Reference numeral 11 denotes an end face Z-shaped interior support piece, and the interior support piece 11 is detachably fixed from the outside (reverse side) of the mounting base plate 18 via a fixing tool 12.

１３はマイクロスイッチ本体で、該マイクロスイッチ本体１３は、取付けベース板１８の一側面（内面）１８ａに固定された不番のバネ受け片と前記支持片１１との間にサンドイッチ状に設けられている。そして、マイクロスイッチ本体１３用の信号線（省略）は、トロヨケ２の下方の側壁に形成した貫通孔を介して外へと導かれる。１４は基端部が内装支持片１１に横設軸架された支軸に設けられ、かつ、自由端部１４ａが錠前の施錠片ａを受けることができるように傾斜する長板状の可動接触片（可動片）である。 Reference numeral 13 denotes a microswitch body. The microswitch body 13 is sandwiched between an unnumbered spring receiving piece fixed to one side surface (inner surface) 18 a of the mounting base plate 18 and the support piece 11. Yes. Then, the signal line (omitted) for the microswitch body 13 is guided to the outside through a through hole formed in the lower side wall of the trolley 2. 14 is a long plate-like movable contact whose base end portion is provided on a support shaft horizontally mounted on the interior support piece 11 and is inclined so that the free end portion 14a can receive the locking piece a before locking. It is a piece (movable piece).

しかして、前記可動片１４は、不番の付勢バネのバネ力に抗して後退動可能であることから、トロヨケ２の切欠状の開口部１５ｃは、可動片１４を受け入れることができる大きさに形成されている。 Since the movable piece 14 can be moved backward against the spring force of an unnumbered biasing spring, the notch-shaped opening 15c of the troyoke 2 is large enough to receive the movable piece 14. Is formed.

ところで、ケース部１５の左右の側壁１５ａの上下の部位には、左右一対の保持ピン逃し用切欠部２０，２０がそれぞれ計４個形成されている。矩形状切欠部２０の縁は、図１で示すように、それぞれ上下一対の可動コア用保持ピン（係合ピン）２１，２１と係合する。これらの切欠部２０の縁は、通常の使用状態では、一つの保持ピン２１の外周面と一部係合する。なお、特に図示しないが、特許文献に記載の実施例のように、トロヨケ２の左右の側壁に可動コア用保持ピン（係合ピン）２１，２１と係合する係合孔をそれぞれ対向形成し、一方、後述する可動コア３の方に前記矩形状切欠部２０を形成しても良い。 Incidentally, a total of four pairs of left and right holding pin relief notches 20 are formed on the upper and lower portions of the left and right side walls 15a of the case portion 15, respectively. As shown in FIG. 1, the edges of the rectangular cutout 20 engage with a pair of upper and lower movable core holding pins (engagement pins) 21 and 21, respectively. The edges of these notches 20 are partially engaged with the outer peripheral surface of one holding pin 21 in a normal use state. Although not particularly illustrated, the engagement holes for engaging the movable core holding pins (engagement pins) 21 and 21 are formed on the left and right side walls of the troyoke 2 so as to face each other as in the embodiment described in the patent document. On the other hand, the rectangular cutout 20 may be formed on the movable core 3 described later.

（４）可動コア３
次に可動コア３について説明する。可動コア３は、図１、図４で示すように、前方から後方へと開口２３を有する箱型形状に形成されている。すなわち、３ａ，３ａは上下の垂直正面壁、３ｂ，３ｂは上下の水平壁、３ｃ，３ｃは左右の対向側壁、３ｄは上の正面壁３ｂと対向する上の垂直後壁（背面）である。 (4) Movable core 3
Next, the movable core 3 will be described. As shown in FIGS. 1 and 4, the movable core 3 is formed in a box shape having an opening 23 from the front to the rear. That is, 3a and 3a are upper and lower vertical front walls, 3b and 3b are upper and lower horizontal walls, 3c and 3c are left and right opposing side walls, and 3d is an upper vertical rear wall (rear surface) facing the upper front wall 3b. .

なお、本実施例の可動コア３では、トロヨケ２の内部空間の下部側に前述したスイッチ部材１９が存在することから、下の正面壁３ｂと対向する下の垂直後壁（背面）は存在しない。したがって、地震時に可動コア３がトロヨケ２の後壁１５ｂ側に移動しても、可動コア３がスイッチ部材１９に衝突する恐れがない。 In the movable core 3 of the present embodiment, since the switch member 19 described above exists on the lower side of the inner space of the troyoke 2, there is no lower vertical rear wall (back surface) facing the lower front wall 3b. . Therefore, even if the movable core 3 moves to the rear wall 15b side of the trolley 2 during an earthquake, there is no possibility that the movable core 3 collides with the switch member 19.

ところで、上下の水平壁３ｂは、上下の保持板８に対して取付け板の機能を有する。したがって、これらの壁３ｂには、例えば符号を付さない固着具用のネジ孔がそれぞれ形成されている。また左右の側壁３ｃには、保持ピン用挿通孔２２がそれぞれ形成されている。その他可動コア３の細部的事項についての説明は割愛する。 By the way, the upper and lower horizontal walls 3 b have a function of a mounting plate with respect to the upper and lower holding plates 8. Accordingly, for example, screw holes for fixing tools without reference numerals are formed in these walls 3b. In addition, holding pin insertion holes 22 are formed in the left and right side walls 3c, respectively. Other detailed explanations of the movable core 3 are omitted.

（５）可動ストライク４
次に可動ストライク４について説明する。本実施例の可動ストライク４は、上下に固着具用の取付け孔５ａ，５ａを有するカバープレート５とは別個の部材である。図１，図２で示すように、可動ストライク４は、カバープレート５よりも短い反面、可動コア３により若干長い。 (5) Movable strike 4
Next, the movable strike 4 will be described. The movable strike 4 of the present embodiment is a separate member from the cover plate 5 having upper and lower attachment holes 5a and 5a for fixing tools. As shown in FIGS. 1 and 2, the movable strike 4 is shorter than the cover plate 5, but slightly longer than the movable core 3.

この可動ストライク４は、正面視逆コ字型形状或いはコ字型形状の前板４ａと、この前板４ａの上下幅広部分の端部をそれぞれ折り曲げて形成した上下端板４ｂ，４ｂと、前板４ａの縦方向の一辺を折り曲げて形成した側端板４ｃとを有し、前記上下幅広部分には、可動コア３の孔と符合する固着具２６用の孔２７がそれぞれ設けられていると共に、前記上下端板４ｂ，４ｂの一端と側端板４ｃの端部との間には、カバープレート５の縦縁の切欠部６ａに対向する小切欠部２８が設けられている。 The movable strike 4 includes a front plate 4a having a reverse U-shape or U-shape in front view, upper and lower end plates 4b and 4b formed by bending the end portions of the upper and lower wide portions of the front plate 4a, A side end plate 4c formed by bending one side of the plate 4a in the vertical direction, and a hole 27 for a fixing tool 26 that is aligned with the hole of the movable core 3 is provided in each of the upper and lower wide portions. A small notch 28 is provided between one end of the upper and lower end plates 4b, 4b and the end of the side end plate 4c so as to face the notch 6a at the vertical edge of the cover plate 5.

（６）上下の保持板８
一方、上下の保持板８は、図１で示すように、トロヨケ２の上下の内壁面と可動コア３の水平上下壁３ｂ，３ｂとの間に設定された上下の空隙部３１内にそれぞれ位置するように線対象状態に配設されている。保持板８は、上下一対で「一組」を構成し、それぞれ断面釣り針状に形成されている。そして、各保持板８の基端部８ａ，８ａは、可動コア３の水平上下壁３ｂに固定手段（例えばオネジ）９を介してそれぞれ固定され、かつ、フック状先端部８ｂは、トロヨケ２の上下の内壁面２ｂにそれぞれ当接する。したがって、特に符号を付さないが、保持板８及び可動コア３の上下壁３ｂの適宜箇所には、取り付け孔がそれぞれ形成されている。 (6) Upper and lower holding plates 8
On the other hand, as shown in FIG. 1, the upper and lower holding plates 8 are respectively positioned in the upper and lower gap portions 31 set between the upper and lower inner wall surfaces of the troyoke 2 and the horizontal upper and lower walls 3 b and 3 b of the movable core 3. As shown in FIG. The holding plate 8 constitutes “one set” in a pair of upper and lower sides, and is formed in a cross-section fishhook shape. The base end portions 8 a and 8 a of each holding plate 8 are fixed to the horizontal upper and lower walls 3 b of the movable core 3 via fixing means (for example, male screws) 9, and the hook-shaped distal end portion 8 b is It abuts on the upper and lower inner wall surfaces 2b, respectively. Therefore, although not indicated in particular, attachment holes are respectively formed at appropriate portions of the holding plate 8 and the upper and lower walls 3b of the movable core 3.

しかして、上下一組の保持板８の先端部８ｂは、少なくとも可動コア３の動きに対応して弾性変形可能（弾性変形機能）である。付言すると、保持板８は、例えば合成樹脂材で形成された「樹脂バネ」であり、望ましくは、地震発生後、外的な衝撃力がなくなった瞬間、材質自体の弾性復帰力により、直ちに元の保持状態を確保するための働き（弾性復帰変形機能）をする。 Thus, the front end portion 8b of the pair of upper and lower holding plates 8 is elastically deformable (elastic deformation function) corresponding to at least the movement of the movable core 3. In other words, the holding plate 8 is a “resin spring” formed of, for example, a synthetic resin material. Preferably, after the occurrence of the earthquake, the moment the external impact force disappears, the elastic plate is immediately restored by the elastic restoring force of the material itself. It works to ensure the holding state (elastic return deformation function).

（７）作用
背景技術の欄で説明したように、スイッチ部材１９の可動板１４は閉扉時に錠前のデッドボルトａが可動ストライク４を介してトロヨケ内に嵌入すると、デッドボルトの先端面により押圧されて回転する。つまり、可動板１４の自由端部１４ａはトロヨケ２の切欠状の開口１５ｃ付近（例えば仮想線の位置）までその付勢バネのバネ力に抗して回転後退する（図７を参照）。 (7) Operation As explained in the background art section, the movable plate 14 of the switch member 19 is pressed by the front end surface of the dead bolt when the lock dead bolt a is inserted into the trolley through the movable strike 4 when the door is closed. Rotate. That is, the free end portion 14a of the movable plate 14 is rotated and retracted against the spring force of the biasing spring to the vicinity of the notch-shaped opening 15c of the troyoke 2 (for example, the position of the phantom line) (see FIG. 7).

そこで、今仮に、地震が発生し、可動ストライク４（可動コア３）がトロヨケ２の後壁１５ｂ側へ後退動したと仮定する。このような場合、デッドボルトの先端面も当然トロヨケ２の後壁１５ｂ側に突っ込んでくることになるが、本実施例では、切欠状の開口部１５ｃは、付勢バネのバネ力に抗して後退する可動接触片を受け入れることができる大きさに形成されていることから、丁度、うまい具合に可動板１４の自由端部１４ａが切欠状の開口部１５ｃ内に収まる。また、可動ストライク４（可動コア３）がトロヨケ２の後壁１５ｂ側へ後退動する場合、スイッチ部材１９が可動ストライク４（可動コア３）に対する障害物にならない。 Thus, it is assumed that an earthquake has occurred and the movable strike 4 (movable core 3) has moved backward toward the rear wall 15b of the troyoke 2. In such a case, the front end surface of the dead bolt also naturally protrudes toward the rear wall 15b side of the troyoke 2. However, in this embodiment, the notched opening 15c resists the spring force of the biasing spring. Therefore, the free end portion 14a of the movable plate 14 fits in the notch-shaped opening 15c just as well. Further, when the movable strike 4 (movable core 3) moves backward toward the rear wall 15b of the trolley 2, the switch member 19 does not become an obstacle to the movable strike 4 (movable core 3).

取付けベース板１８に取付けたスイッチ部材１９は一例である。したがって、例えば磁気感応型スイッチ部材に置換しても良い。 The switch member 19 attached to the attachment base plate 18 is an example. Accordingly, for example, a magnetically sensitive switch member may be substituted.
