Description

本発明は、ラッチ錠における内外気圧差解消装置に関する。 The present invention relates to an internal / external air pressure difference elimination device for a latch lock.

特許文献１は、出願人が貴庁に提案したものである。この特許文献１に記載の発明の課題は内外気圧差解消装置の機能を確実に実現することであり、その解決手段は、「扉７に設けられると共に、錠箱８内に突出する作動片２３，３５を有する内外の操作部材９、１０と、前記扉の自由端部の錠箱内に設けられかつ前記内外の操作部材のいずれかの操作力によって作動する駆動部材５１と、前記錠箱内に設けられかつ前記駆動部材の駆動力によりラッチ部材１１の規制を解くラッチ規制部材４１と、前記駆動部材のさらなる駆動力により水平方向へ移動して扉枠側の当接部７０に圧接する圧接力が扉を開く方向に作用する反力と成る押圧部材６１とを備えたラッチ錠における内外気圧差解消装置に於いて、駆動部材５１は、駆動スライダー５２と、該駆動スライダーに追動或いは共働するようにかつ作動片２３，３５から所定間隔離間した位置に存在する支軸５５に軸支された共働レバー５３を含み、該駆動部材５１と前記押圧部材６１との間には、駆動力によりラッチ規制部材４１がラッチ部材１１の規制を解いた後に押圧部材６１を始動させる押圧部材用タイミングラグ手段５０を設けた内外気圧差解消装置」である。 Patent Document 1 is proposed by the applicant to your office. The subject of the invention described in Patent Document 1 is to reliably realize the function of the internal / external air pressure difference elimination device. The solution is “operating piece 23 provided in door 7 and protruding into lock box 8. , 35, inner and outer operation members 9, 10; a drive member 51 provided in a lock box at the free end of the door and operated by an operating force of either the inner or outer operation member; A latch regulating member 41 that releases the regulation of the latch member 11 by the driving force of the driving member, and a pressure contact that moves in the horizontal direction by the further driving force of the driving member and presses against the contact portion 70 on the door frame side In the internal / external air pressure difference canceling device in the latch lock provided with the pressing member 61 that acts as a reaction force acting in the direction in which the door opens, the driving member 51 is driven or shared by the driving slider 52 and the driving slider. To work Including a cooperating lever 53 that is pivotally supported by a support shaft 55 that is located at a predetermined distance from the operating pieces 23, 35, and between the driving member 51 and the pressing member 61 is latched by a driving force. An internal / external air pressure difference elimination device provided with a pressing member timing lag means 50 for starting the pressing member 61 after the member 41 releases the restriction of the latch member 11.

付言すると、上記内外気圧差解消装置は、ラッチ部材１１がラッチ規制部材４１からの係止が解かれ後に、内外の操作部材９、１０の作動片２３，３５のいずれかの押圧力により作動する二股状の共働レバー５３を介して押圧部材６１を前方に押し出すというものである。そのために、前記押圧部材用タイミングラグ手段５０は、例えば駆動部材５１を構成する矩形開口５２ｃを有するブロック状の駆動スライダー５２の下面と、前記二股状の共働レバー５３の水平方向の係合腕（第１係合腕）５３ｂの上辺との間に設定された「所要の間隙」である。 In addition, the internal / external air pressure difference canceling device is operated by the pressing force of the operating pieces 23 and 35 of the internal and external operating members 9 and 10 after the latch member 11 is released from the latch restricting member 41. The pressing member 61 is pushed forward through the bifurcated cooperative lever 53. For this purpose, the timing lug means 50 for the pressing member includes, for example, a lower surface of a block-like drive slider 52 having a rectangular opening 52c constituting the drive member 51, and a horizontal engagement arm of the bifurcated cooperating lever 53. (First engagement arm) “required gap” set between the upper side of 53b.

しかしながら、前記所要の間隙５０は、二股状の共働レバー５３を軸支する支軸５５にその中央部が巻装された駆動バネ（ねじりバネ）５４のバネ力に頼るものであることから、駆動バネ５４のバネ力に問題が生ずると、内外気圧差解消装置の機能を確実に実現することが困難であるという課題が生じた（符号は特許文献１のもの）。また特許文献１の公知発明は、後述する発明の課題に於いて、解決すべき幾つかの問題点があった。 However, the required gap 50 depends on the spring force of a drive spring (torsion spring) 54 having a central portion wound around a support shaft 55 that pivotally supports a bifurcated cooperating lever 53. When a problem occurs in the spring force of the drive spring 54, a problem arises that it is difficult to reliably realize the function of the internal / external air pressure difference canceling device (reference numeral 1). Further, the known invention of Patent Document 1 has several problems to be solved in the problems of the invention described later.

（１）環境部材
まず、図１を参照にして環境部材を説明する。なお、当業者にとって自明の、シリンダ錠、デッドボルトの出没機構、デッドボルト、サムターン装置等の図示及び説明は省略する。 (1) Environmental member First, an environmental member is demonstrated with reference to FIG. In addition, illustration and description of a cylinder lock, a dead bolt in / out mechanism, a dead bolt, a thumb turn device, etc., which are obvious to those skilled in the art, are omitted.

図１は扉枠側の部材と扉側の部材を示す環境説明図で、特に、扉の外壁面と、内外のプッシュ・プル方式のハンドルと、錠箱のフロントが見える斜視図である。この図に於いて、１は玄関扉用の扉枠で、この扉枠１の縦枠には錠受け２が縦方向に固定されている。錠受け２には、ラッチ受け穴４、スイング式押圧体用の切欠部分５がそれぞれ形成されている。また扉枠１の縦枠には、戸当り６、前記錠受け２を取付けるための不番の切欠状凹所がそれぞれ形成されている。本発明の本質的事項ではないが、実施形態如何によって、前記戸当り６には、戸当り６と扉７との隙間をシールするパッキン（ガスケット）が適宜に設けられている。 FIG. 1 is an environment explanatory view showing a door frame side member and a door side member. In particular, FIG. 1 is a perspective view showing the outer wall surface of the door, the inner and outer push-pull handles, and the front of the lock box. In this figure, 1 is a door frame for an entrance door, and a lock holder 2 is fixed to the vertical frame of the door frame 1 in the vertical direction. The lock receiver 2 is formed with a latch receiving hole 4 and a notch portion 5 for a swing type pressing body. The door frame 1 is formed with a door frame 6 and a numbered notch-like recess for attaching the lock receiver 2. Although not an essential matter of the present invention, depending on the embodiment, the door stop 6 is appropriately provided with a packing (gasket) for sealing a gap between the door stop 6 and the door 7.

したがって、扉７が室外の方向に開動する開閉体であれば、室内側が負圧となることで、扉７の開閉端部７ａの内側（図１では向こう側の内壁面）は、パッキンを介して又は介さないで戸当り６に押付けられる。 Therefore, if the door 7 is an opening / closing body that opens in the outdoor direction, the interior side of the door 7 has a negative pressure, so that the inside of the opening / closing end portion 7a of the door 7 (the inner wall surface on the far side in FIG. 1) passes through the packing. Pressed against the door stop 6 without or intervening.

一方、扉７の吊元と反対側の開閉端部７ａには、ラッチ錠Ｘの錠箱８が内装されている。ここで「ラッチ錠」とは、ラッチボルトや反転ラッチと称されるラッチ部材を有する錠前のことで、デッドボルトのみを有する本締り錠を除く。したがって、ラッチボルトのみを有する空錠、ラッチボルト又は反転ラッチのいずれかを有すると共に、デッドボルトを持つ錠前（例えば玄関錠）は、ここでのラッチ錠Ｘに含まれる。 On the other hand, a lock box 8 of a latch lock X is housed in the open / close end 7a on the side opposite to the hanging base of the door 7. Here, the “latch lock” is a lock having a latch member called a latch bolt or a reverse latch, and excludes a lock lock having only a dead bolt. Therefore, a lock having only a latch bolt, a latch bolt or a reverse latch and having a dead bolt (for example, a front door lock) is included in the latch lock X here.

図１で示すように、このラッチ錠Ｘの錠箱８の外壁面側（つまり扉７の室外側の面）には、プッシュ・プル方式の外側操作部材１０が縦或いは横方向に設けられている。一方、扉７の室内側にプッシュ・プル方式の内側操作部材９が縦或いは横方向に設けられている。 As shown in FIG. 1, on the outer wall surface side of the lock box 8 of the latch lock X (that is, the outer surface of the door 7), a push-pull type outer operation member 10 is provided in the vertical or horizontal direction. Yes. On the other hand, a push-pull type inner operation member 9 is provided on the indoor side of the door 7 in the vertical or horizontal direction.

１１は外側操作部材１０の操作力によってラッチ規制部材からの規制（ロック状態）が解かれるラッチ部材（本実施例では反転ラッチ）、そして、１２は後述する押圧部材である。なお、符号１３は錠受け２に直交する扉枠１の縦枠の前面に固定される縦長状補強片で、この補強片１３は縦枠に不番の切欠凹所を形成するので、それを補強するためのものである。補強片１３は発明の本質的事項ではない。 Reference numeral 11 denotes a latch member (inverted latch in this embodiment) in which restriction (locked state) from the latch restriction member is released by the operating force of the outer operation member 10, and reference numeral 12 denotes a pressing member described later. Reference numeral 13 denotes a vertically long reinforcing piece fixed to the front surface of the vertical frame of the door frame 1 orthogonal to the lock receiver 2, and this reinforcing piece 13 forms an unnotched notch in the vertical frame. It is for reinforcement. The reinforcing piece 13 is not an essential matter of the invention.

上記構成に於いて、扉７が室外の方向に開動する開閉体であれば、室内側が負圧となることで、扉７の開閉端部７ａの内側（図１では向こう側の内壁面）は、戸当り６に押付けられる。したがって、扉７を開け難いという問題点があり、それを解決するために「内外気圧差解消装置」が加味されている。 In the above configuration, if the door 7 is an opening / closing body that opens in the outdoor direction, the inner side of the opening / closing end portion 7a of the door 7 (the inner wall surface on the far side in FIG. 1) is caused by negative pressure on the indoor side. , Pressed against the door. Therefore, there is a problem that it is difficult to open the door 7, and “internal / external air pressure difference elimination device” is added to solve the problem.

次に、図２及び図３を参照にして、内外のハンドル装置の一例を説明する。これらの図に於いて、符号Ｙは室内のハンドル装置、一方、Ｚは室外のハンドル装置である。これらの図から明らかなように、内外の操作手段９、１０はプッシュ・プル方式のハンドルである。図３で示すように、プル側の外側操作部材１０は、扉を開く矢印Ａ方向へプルされる。また、プッシュ側の内側操作部材９も同様に扉を開く矢印Ａ方向へプッシュされる。 Next, an example of the inner and outer handle devices will be described with reference to FIGS. In these drawings, the symbol Y is an indoor handle device, while Z is an outdoor handle device. As is apparent from these drawings, the inner and outer operating means 9 and 10 are push-pull type handles. As shown in FIG. 3, the pull-side outer operation member 10 is pulled in the direction of arrow A that opens the door.

（２）本発明の主要部
本発明の内外気圧差解消装置は、前述したラッチ錠Ｘを前提とする。しかして、本発明の内外気圧差解消装置は、扉７に設けられると共に、錠箱８内に突出する内外の作動片３５、２３を有する内外の操作部材９、１０と、前記扉の開閉端部７ａの錠箱８内に設けられかつ前記操作部材の操作力によって作動する駆動部材５１と、前記錠箱内に設けられかつ前記駆動部材の駆動力によりラッチ部材１１の規制を解くラッチ規制部材４１と、前記駆動部材のさらなる駆動力により水平方向へ移動して扉枠側の当接部に圧接する圧接力が扉を開く方向に作用する反力と成る押圧部材６１とを備えたラッチ錠Ｘにおける内外気圧差解消装置に於いて、前記駆動部材５１は、前記作動片３５、２３の押圧力により作動する略矩形開口を有するスライダー５２と、該スライダーに共働するようにかつ前記作動片３５、２３から所定間隔離間した位置に存在する支軸５５に軸支された二股状の共働レバー５３とから成り、また前記押圧部材６１は、前記駆動部材５１を介してかつ付勢手段６７の付勢力に抗して前記錠箱８のフロント８ａ側にスライドするブロック状の摺動制御体（押圧本体）６２と、この摺動制御体の先端部にタイミングラグ用の間隙６３を有する枠状の連係手段６４を介して連結されていると共に、垂直軸６６を介して軸支されかつその先端部側に前記フロントから常に突出する係合先端部を有するスイング式押圧体６５とから成る。 (2) Main part of this invention The internal / external air pressure difference elimination apparatus of this invention presupposes the latch lock X mentioned above. Thus, the internal / external air pressure difference eliminating device of the present invention is provided on the door 7 and has internal and external operation members 9 and 10 having internal and external operating pieces 35 and 23 projecting into the lock box 8, and the open / close end of the door. A driving member 51 provided in the lock box 8 of the portion 7a and actuated by the operating force of the operating member; and a latch restricting member provided in the lock box and releasing the restriction of the latch member 11 by the driving force of the driving member 41, and a pressing member 61 that is a reaction force that acts in the direction to open the door by the pressing force that moves in the horizontal direction by the further driving force of the driving member and presses against the contact portion on the door frame side. In the internal / external air pressure difference canceling apparatus at X, the driving member 51 includes a slider 52 having a substantially rectangular opening that is operated by the pressing force of the operating pieces 35 and 23, and the operating piece so as to cooperate with the slider. 35, 23 The bifurcated cooperating lever 53 is pivotally supported by a support shaft 55 that is located at a predetermined distance from the support member 55, and the pressing member 61 is biased by the biasing means 67 via the drive member 51. A block-like sliding control body (pressing body) 62 that slides against the front 8a side of the lock box 8 and a frame-like linkage having a gap 63 for a timing lag at the tip of the sliding control body The swing-type pressing body 65 is connected via a means 64 and is supported by a vertical shaft 66 and has an engaging tip that always protrudes from the front side on the tip side.

前述したように、本発明が特許文献１と主に異なる点は、押圧部材６１が、摺動制御体６２と、この摺動制御体の先端部にタイミングラグ用の間隙６３を有する連係手段６４を介して連結されているスイング式押圧体６５とから成ることである（図１４参照）。したがって、ここで、本発明の主な作用について説明すると、ラッチ規制部材４１と係合する駆動部材５１のスライダー５２が作動片により始動して前記ラッチ規４１がラッチ部材１１の規制を解いた後に、前記駆動部材５１の二股状の共働レバー５３を介して前進する摺動制御体（押圧本体）６２の先端面とスイング式押圧体６５の後端面の角部分との間の間隙６３がなくなり、その状態を維持しながら前記摺動制御体（押圧本体）６２が前記スイング式押圧体６５を押し続けるので（図１６参照）、スイング式押圧体６５が水平状態に回転して扉枠１側の当接部７０に圧接する圧接力が扉を開く方向に作用する反力と成ることである（第１の特徴部分）。そして、本発明のラッチ錠Ｘは、左勝手か又は右勝手かのいずれかに使用可能であることである（第２の特徴部分）。さらに、略矩形開口を有するスライダー５２や摺動制御体（押圧本体）６２の構成も改良している（第３２の特徴部分）。 As described above, the present invention is mainly different from Patent Document 1 in that the pressing member 61 includes the sliding control body 62 and the linkage means 64 having the timing lag gap 63 at the tip of the sliding control body. It is that it consists of the swing type press body 65 connected via (refer FIG. 14). Therefore, here, the main function of the present invention will be described. After the slider 52 of the drive member 51 that engages with the latch restricting member 41 is started by the operating piece, the latch reference 41 releases the restriction of the latch member 11. The gap 63 between the front end surface of the sliding control body (pressing main body) 62 that moves forward via the bifurcated cooperating lever 53 of the driving member 51 and the corner portion of the rear end surface of the swing type pressing body 65 is eliminated. Since the sliding control body (pressing body) 62 continues to push the swing type pressing body 65 while maintaining this state (see FIG. 16), the swing type pressing body 65 rotates in a horizontal state and the door frame 1 side. That is, the pressing force that is pressed against the contact portion 70 becomes a reaction force that acts in the direction of opening the door (first characteristic portion). And the latch lock X of this invention is that it can be used for either left-hand or right-hand (2nd characteristic part). Furthermore, the configurations of the slider 52 and the sliding control body (pressing body) 62 having a substantially rectangular opening are also improved (a thirty-second characteristic portion).

（３）ラッチ部材１１、ラッチ規制部材４１
図４はラッチ部材１１及びラッチ規制部材４１の一例を示す。ここでは図４及び図１５を参照にして、ラッチ部材１１と、該ラッチ部材を仮施錠状態に規制（保持）するラッチ規制部材４１を説明する。なお、ラッチ部材１１としての反転ラッチ、反転ラッチ１１を仮施錠するラッチ規制部材（ロッキングピース）は、当業者によって自明事項であるから、ここでは細部的構成の説明は割愛する。反転ラッチ１１及びラッチ規制部材４１は、例えば特開平８−１００５５９号公報、特開平１１−１４８２５９号公報等と同様であり、特に異なる点は、ラッチ規制部材４１の一方が、その支軸（実施例では上下一対の支軸）４２、４２よりも錠箱８の後壁８ｂ方向へ所定量延在する係合腕４３を有し、該係合腕４３の先端部に設けた水平ローラ４３ａが、駆動部材５１を構成する矩形ブロック形状のスライダー５２の一側壁（垂直側壁の外面）５２ａの下端部に設けた突片状の係止部分５２ｂに摺接係合する点である。４５はラッチ部材１１用付勢バネ、４６はラッチ規制部材４１用付勢バネである。 (3) Latch member 11 and latch restricting member 41
FIG. 4 shows an example of the latch member 11 and the latch restricting member 41. Here, the latch member 11 and the latch restricting member 41 that restricts (holds) the latch member to the temporarily locked state will be described with reference to FIGS. 4 and 15. In addition, since the latch control member (locking piece) which temporarily locks the inversion latch as the latch member 11 and the inversion latch 11 is obvious to those skilled in the art, description of a detailed structure is omitted here. The inversion latch 11 and the latch restricting member 41 are the same as, for example, Japanese Patent Laid-Open Nos. 8-100159, 11-148259, and the like, except that one of the latch restricting members 41 has its support shaft (implemented). In the example, a pair of upper and lower support shafts) 42, 42 has an engagement arm 43 extending a predetermined amount in the direction of the rear wall 8 b of the lock box 8, and a horizontal roller 43 a provided at the tip of the engagement arm 43 includes This is a point of sliding engagement with a protruding piece-like locking portion 52b provided on the lower end portion of one side wall (outer surface of the vertical side wall) 52a of the rectangular block-shaped slider 52 constituting the driving member 51. 45 is an urging spring for the latch member 11, and 46 is an urging spring for the latch restricting member 41.

なお、図４の実施例では、ラッチ規制部材４１が互いに揺動するように組み合わせられた上下一組のロッキングピースであるが、例えば特開２００１−２２５５１０号公報の図４に記載されているように、係合腕４３を有する片方だけであっても良い。また、ラッチ規制部材４１の係脱機構は当業者が任意に設計変更することができる事項である点は指摘するまでもない。 In the embodiment of FIG. 4, the latch restricting member 41 is a pair of upper and lower locking pieces combined so as to swing with respect to each other. For example, as shown in FIG. 4 of Japanese Patent Laid-Open No. 2001-225510. In addition, only one side having the engaging arm 43 may be used. Further, it goes without saying that the engagement / disengagement mechanism of the latch restricting member 41 is a matter that can be arbitrarily changed by those skilled in the art.

（４）駆動部材５１
図５及び図６を参照にして駆動部材５１を説明する。駆動部材５１は、作動片２３、３５の押圧力により作動するスライダー５２（図５）と、該スライダーに共働するようにかつ前記作動片から所定間隔離間した位置に存在する支軸５５に軸支された共働レバー５３（図６）とから成る。なお、本発明では、スイング式押圧体の後端の角部分と摺動制御体の先端部の前面との間にタイミングラグができるように、例えば平面視略横倒れＵ字形状或いは略Ｖ字形状（内側に間隙を有する枠形状）の連係手段６４を前記スイング式押圧体と摺動制御体に設けたので、特許文献１の如く、必ずしも押圧部材用タイミングラグ手段を設定するために駆動バネ（ねじりバネ）を用いる必要性がない。したがって、例えば駆動部材５１のスライダー５２の上端部とクランク形状或いは二股形状の共働レバー５３の軸支された部分から上方向延在する第２係合腕５３ｂとの間に間隙を設けていない。 (4) Driving member 51
The drive member 51 will be described with reference to FIGS. The driving member 51 has a slider 52 (FIG. 5) that is operated by the pressing force of the operating pieces 23 and 35, and a support shaft 55 that cooperates with the slider and is located at a predetermined distance from the operating piece. It consists of a supported cooperating lever 53 (FIG. 6). In the present invention, for example, a substantially U-shaped or substantially V-shaped side-view in plan view is formed so that a timing lag is formed between the corner of the rear end of the swing type pressing body and the front surface of the front end of the sliding control body. Since the linking means 64 having a shape (a frame shape having a gap on the inside) is provided on the swing type pressing body and the sliding control body, as in Patent Document 1, a drive spring is not necessarily used to set the timing lug means for the pressing member. There is no need to use a (torsion spring). Therefore, for example, no gap is provided between the upper end portion of the slider 52 of the driving member 51 and the second engagement arm 53b extending upward from the shaft-supported portion of the crank-shaped or bifurcated cooperating lever 53. .

実施形態のスライダー５２は、特許文献１のスライダーと同様に矩形開口を有するブロックであるものの、該ブロックの垂直側壁５２ａから連続するやや弧状の上壁５２ｃには所定間隔を有して左右一対の突壁部分５２ｄ、５２ｄが形成され、該左右一対の突壁部分の間に共働レバー５３の水平方向の第１係合腕５３ａが規制された状態で係合している。なお、５２eは縦長開口、５２fは案内突起である。 Although the slider 52 of the embodiment is a block having a rectangular opening like the slider of Patent Document 1, a slightly arcuate upper wall 52c continuous from the vertical side wall 52a of the block has a predetermined interval and a pair of left and right. Projecting wall portions 52d and 52d are formed, and the horizontal first engaging arm 53a of the cooperating lever 53 is engaged between the pair of left and right projecting wall portions in a restricted state. In addition, 52e is a vertically long opening, and 52f is a guide protrusion.

また実施形態の共働レバー５３は、不番の軸筒部（中央部）を有し、該中央部から略水平方向に延びる第１係合腕５３ａは、前述したようにスライダー５２の弧状上壁５２ｃの中央部に係合支持され、一方、前記第１係合腕５３ａに対して略直角の角度を有して垂直方向に延びる第２係合腕５３ｂは、前述したように摺動制御体６２の切欠状の係合部分６２ｂに係合する。 Further, the cooperating lever 53 of the embodiment has an unnumbered shaft tube portion (center portion), and the first engagement arm 53a extending from the center portion in the substantially horizontal direction is on the arc shape of the slider 52 as described above. The second engagement arm 53b that is engaged and supported at the central portion of the wall 52c and that extends in the vertical direction at an angle substantially perpendicular to the first engagement arm 53a is sliding controlled as described above. It engages with a notch-like engagement portion 62b of the body 62.

（５）押圧部材６１の構成
次に、例えば右勝手仕様の図４、図７及び図８を参照にして押圧部材６１を構成する摺動制御体６２と、該摺動制御体６２に連係手段６４を介して接続するスイング式押圧体６５を説明する。実施形態の摺動制御体６２は、錠箱８の下部空間に配設したラッチ部材としての反転ラッチ１１の位置に対して、錠箱８内の上方空間に位置するように配設されている。周知のように、反転ラッチ１１は水平回転しながら進退動可能である。摺動制御体６２も反転ラッチ１１と同様に進退動可能であるものの、反転ラッチの如く水平回転はしない。一方、スイング式押圧体６５は、垂直軸６６を支点にして所定量水平回転可能である。 (5) Configuration of the pressing member 61 Next, for example, referring to FIGS. 4, 7 and 8 of the right-handed specification, the sliding control body 62 constituting the pressing member 61, and the linking means to the sliding control body 62 The swing-type pressing body 65 connected via 64 will be described. The sliding control body 62 of the embodiment is disposed so as to be positioned in the upper space in the lock box 8 with respect to the position of the reversal latch 11 as a latch member disposed in the lower space of the lock box 8. . As is well known, the inversion latch 11 can move forward and backward while rotating horizontally. Although the sliding control body 62 can move forward and backward similarly to the reversing latch 11, it does not rotate horizontally like the reversing latch. On the other hand, the swing-type pressing body 65 can be rotated horizontally by a predetermined amount with the vertical shaft 66 as a fulcrum.

例えば図７を基準にすると、摺動制御体６２の外観形状は、上面の略中央部及び下面の略中央部寄りの部位が段差状に形成されたブロック状の態様のものであり、前記上面の略中央部段差状の垂直面は、付勢手段６７の後端部を受けるバネ端支持部分６２ａである。このバネ端支持部分６２ａは、実施形態では小突起である。一方、下面の略中央部寄りの部位の段差状の垂直面は、共働レバー５３の垂直方向の第２係合腕５３ｂが係合する切欠状の係合部分６２ｂである。 For example, with reference to FIG. 7, the external appearance of the sliding control body 62 is a block-like aspect in which the portion near the center of the upper surface and the portion near the center of the lower surface is formed in a stepped shape. The substantially central stepped vertical surface is a spring end support portion 62 a that receives the rear end portion of the urging means 67. The spring end support portion 62a is a small protrusion in the embodiment. On the other hand, the step-like vertical surface near the center of the lower surface is a notch-like engagement portion 62 b with which the second engagement arm 53 b in the vertical direction of the cooperating lever 53 engages.

しかして、前記バネ端支持部分６２ａを基準するブロック状の先端部６２ｃの上面は上面視略長方形状であり、また先端部６２ｃの前面は側面視略四角形状であり、さらに、前記上面及び前面に直交する左右の側壁面は略長方形状である。 The upper surface of the block-shaped tip end portion 62c with respect to the spring end support portion 62a is substantially rectangular when viewed from above, and the front surface of the tip end portion 62c is substantially square when viewed from the side. The left and right side wall surfaces orthogonal to are substantially rectangular.

ここで、図１１を参照にして「扉の開き勝手」について簡単に説明する。図１１に於いて、図面の左側が右勝手（右吊元）である。これは扉の吊元に取付けた蝶番（丁番）が見える側に人が立って、右側に前記蝶番が見える場合を「右勝手（右吊元）」といい、扉７は矢印に示す方向に開く。したがって、扉枠１の左側に錠受け２が設けられている。一方、図１１に於いて、図面の右側が左勝手（左吊元）であり、扉枠１の左側に蝶番が見え、錠受け２は扉枠１の右側に錠受け２が設けられている。 Here, with reference to FIG. 11, “door opening ability” will be briefly described. In FIG. 11, the left side of the drawing is the right hand (right hanger). This is called “right hand (right hanging base)” when a person stands on the side where the hinge (hinge) attached to the hanging base of the door is visible and the hinge is visible on the right side, and the door 7 is in the direction indicated by the arrow. Open to. Therefore, the lock receiver 2 is provided on the left side of the door frame 1. On the other hand, in FIG. 11, the right side of the drawing is the left hand (left-handed), the hinge is visible on the left side of the door frame 1, and the lock receiver 2 is provided with the lock receiver 2 on the right side of the door frame 1. .

本発明の実施形態では、例えば図７で示すように、摺動制御体６２を右勝手又は左勝手のいずれにでも使用することができるように、前記先端部６２ｃの上面、前面及び左右の側壁面に連係手段６４用の合計３個の嵌合溝６８が、上面から下面に至らない略中央部まで垂直に形成されている。付言すると、３個の嵌合溝６８の中で、左右の側壁面側にそれぞれ位置する切欠状嵌合溝６８ａ、６８ｃは上面視左右対称の略Ｌ字形状であり、これら左右の切欠状嵌合溝６８ａ、６８ｃの間に位置する中央の切欠状嵌合溝６８ｂは上面視略Ｔ字形状である。 In the embodiment of the present invention, for example, as shown in FIG. 7, the top surface, the front surface, and the left and right sides of the tip portion 62c are used so that the sliding control body 62 can be used for either the right hand or the left hand. A total of three fitting grooves 68 for the linking means 64 are vertically formed on the wall surface from the upper surface to the substantially central portion that does not reach the lower surface. In addition, of the three fitting grooves 68, the notch-like fitting grooves 68a and 68c respectively positioned on the left and right side wall surfaces are substantially L-shaped symmetrically in a top view. A central notch-like fitting groove 68b located between the mating grooves 68a and 68c has a substantially T-shape when viewed from above.

一方、前記バネ端支持部分６２ａを基準するブロック状の後端部６２ｄの左右の側壁並びに略中央部の左右の側壁には、それぞれ錠箱８に案内される小突起状第１案内部分６２ｅが複数個設けられている。さらに、中央部段差状の垂直面は付勢手段６７の後端部を受けるバネ端支持部分６２ａであることから、ブロック状の後端部６２ｄの左右の側壁には、摺動制御体６２を安定した状態で案内することができるように錠箱に固定された案内軸に案内される案内長孔（水平長孔）６２ｆが形成されている。また、小突起状第１案内部分６２ｅは、ストッパー機能を有するので、安定した状態で進退動した摺動制御体６２を、所定の位置に停止させる。加えて、
ここで、連係手段６４について説明すると、連係手段６４は、略Ｕ字形状或いは略Ｖ字形状に形成され、かつ指状両端部に外方向に突出する係止部分を有する枠状連結突片６４ａと、スイング式押圧体６５の後端部に設けられた垂直方向の可動連結ピン（連結軸）６４ｂである。ところで、図９はラッチ錠を右勝手に使用する場合における平面視略横倒れ枠形状の連係手段（枠状連結突片６４ａ）の接続態様の概略説明図で、（ａ）は連係手段を摺動制御体の嵌合溝に嵌め込む前、（ｂ）は連係手段を摺動制御体の嵌合溝に嵌め込んだ場合である。一方、図１０はラッチ錠を左勝手に使用する場合における平面視略横倒れ枠形状の連係手段（枠状連結突片６４ａ）の接続態様の概略説明図で、（ａ）は連係手段を摺動制御体の嵌合溝に嵌め込む前、（ｂ）は連係手段を摺動制御体の嵌合溝に嵌め込んだ場合である。 On the other hand, on the left and right side walls of the block-shaped rear end portion 62d with reference to the spring end support portion 62a and the left and right side walls of the substantially central portion, there are small projection-like first guide portions 62e guided to the lock box 8, respectively. A plurality are provided. Further, since the vertical step-shaped vertical surface is the spring end support portion 62a that receives the rear end portion of the biasing means 67, the sliding control body 62 is provided on the left and right side walls of the block-shaped rear end portion 62d. A guide long hole (horizontal long hole) 62f guided by a guide shaft fixed to the lock box is formed so that the guide can be stably provided. Moreover, since the small protrusion-shaped first guide portion 62e has a stopper function, the sliding control body 62 that has advanced and retracted in a stable state is stopped at a predetermined position. in addition,
Here, the linking means 64 will be described. The linking means 64 is formed in a substantially U shape or a substantially V shape, and has a frame-like connecting protrusion 64a having locking portions protruding outward at both finger-like ends. And a vertical movable connecting pin (connecting shaft) 64b provided at the rear end of the swing type pressing body 65.

次に、スイング式押圧体６５を説明する。スイング式押圧体６５は、摺動制御体６２の進退動に共働して水平方向へ所定量回転することができるように垂直軸６６及び上下の軸受け部材６９、６９を介して錠箱８内のフロント８ａ付近に軸支されている。
このスイング式押圧体６５も前記摺動制御体６２と同様にブロック体に形成しても良いが、本実施形態では小片板体に形成している。 Next, the swing type pressing body 65 will be described. The swing-type pressing body 65 is provided in the lock box 8 via the vertical shaft 66 and the upper and lower bearing members 69 and 69 so as to be able to rotate by a predetermined amount in the horizontal direction in cooperation with the forward and backward movement of the sliding control body 62. Is supported near the front 8a.
The swing-type pressing body 65 may be formed as a block body similarly to the sliding control body 62, but in the present embodiment, it is formed as a small plate body.

スイング式押圧体６５の後端部６５ａの一側面側には垂直軸６６が設けられ、一方、後端部６５ａの他側面側には前述した可動連結ピン（連結軸）６４ｂが一体的に設けられている。そして、スイング式押圧体６５の後端部６５ａは、摺動制御体６２の先端部に連結軸６４ｂを介して連結され、該連結軸６４ｂが摺動制御体６２の連結突片６４ａの先端部６４ｃの内側に係合すると、図８で示すように連結突片６４ａと摺動制御体６２の連結部分の端面との間に所要の間隙６３が存在する。 A vertical shaft 66 is provided on one side surface of the rear end portion 65a of the swing type pressing body 65, while the movable connecting pin (connecting shaft) 64b described above is integrally provided on the other side surface side of the rear end portion 65a. It has been. The rear end portion 65 a of the swing-type pressing body 65 is connected to the distal end portion of the sliding control body 62 via a connecting shaft 64 b, and the connecting shaft 64 b is connected to the distal end portion of the connecting projection piece 64 a of the sliding control body 62. When engaged with the inner side of 64c, a required gap 63 exists between the connecting protrusion 64a and the end face of the connecting portion of the sliding control body 62 as shown in FIG.

なお、スイング式押圧体６５の形状はこれに限定されるものではなく、肉厚の幅広後端部（内端部）と、該幅広後端部に親指状に連設する肉薄の係合先端部とからなるものでも良いが、このようにスイング式押圧体６５の上面と下面の形状が異なる場合には、右勝手用のスイング式押圧体と左勝手用のスイング式押圧体を用意しておく必要がある。
ここで、図１４を参照にして、摺動制御体６２とスイング式押圧体６５の連係構造を説明する。スイング式押圧体６５は、錠箱８内に垂直軸６６を介して軸支されると、操作部材を操作しない常態では、後側の縁辺ａと、これに略直交する扉枠側の当接部７０と対向する側の縁辺ｂは、錠箱８の幅広側壁の内壁面に対して略均等角度（例えば４５度づつ）にそれぞれ交差している。 The shape of the swing-type pressing body 65 is not limited to this, and is a thick wide rear end (inner end) and a thin engagement tip that is connected to the wide rear end like a thumb. However, if the shape of the upper surface and the lower surface of the swing-type pressing body 65 is different, prepare a swing-type pressing body for the right hand and a swing-type pressing body for the left hand. It is necessary to keep.
Here, with reference to FIG. 14, the linkage structure of the sliding control body 62 and the swing type pressing body 65 will be described. When the swing-type pressing body 65 is pivotally supported in the lock box 8 via the vertical shaft 66, in a normal state in which the operation member is not operated, the rear edge a is brought into contact with the door frame side substantially orthogonal thereto. The edge b on the side facing the portion 70 intersects the inner wall surface of the wide side wall of the lock box 8 at substantially equal angles (for example, 45 degrees).

また前記後側の縁辺ａと交差する室外側の縁辺ｃは弧状乃至錠箱８の幅広側壁の内壁面に当接する曲線或は垂直線と成り、さらに、前記扉枠１側の当接部７０と対向する側の縁辺ｂと前記室外側の縁辺ｃは、先端部付近に至るにしたがって次第に幅が狭くなっている。そして、前述した指状の係合先端部６５ｂは、錠箱８のフロント８ａから常に食み出している。 An outdoor side edge c intersecting with the rear side edge a is a curved line or a vertical line that contacts the inner wall surface of the wide side wall of the arc box or the lock box 8, and further, the contact part 70 on the door frame 1 side. The width of the edge b on the opposite side and the edge c of the outdoor side are gradually narrower toward the vicinity of the tip. The finger-like engagement tip 65b described above always protrudes from the front 8a of the lock box 8.

なお、前述した上の軸受け部材６９は、スイング式押圧体６５用の軸受け機能の他、不番のバネ端支持部を有し、付勢手段６７の先端部を支持する機能も有する。 The above-described upper bearing member 69 has a bearing function for the swing-type pressing body 65, has an unnumbered spring end support portion, and also has a function of supporting the distal end portion of the urging means 67.

（６）扉枠側の当接部
図１及び図１４を参照にして扉枠１側の当接部７０を説明する。本実施例では、当接部７０は、図１で示すように、ラッチ受け穴４等を有する「いわゆる１枚のストライク板」の裏側（例えばトロヨケ）に配設されているが、もちろん、設計如何によっては、周知のストライク板等と、当接部７０を有する内外気圧差解消装置の受け具とは別体に成形されたものであっても良い。 (6) Contact part on the door frame side The contact part 70 on the door frame 1 side will be described with reference to FIGS. 1 and 14. In this embodiment, as shown in FIG. 1, the abutting portion 70 is disposed on the back side (for example, Troyoke) of “a single strike plate” having the latch receiving hole 4 and the like. Depending on the case, the well-known strike plate or the like and the receiving device of the internal / external air pressure difference elimination device having the contact portion 70 may be formed separately.

さて、この当接部７０は、基本的には、錠受け２内に固定された支持ブラケット７１と、これに軸支された垂直ローラ７２とから成る。支持ブラケット７１は、扉枠１に形成された切欠状の凹所７３に固設され、この凹所底面に対して、錠箱８のフロント８ａ（扉７の木口）に向かって延出するように構成される。 The abutting portion 70 basically includes a support bracket 71 fixed in the lock receiver 2 and a vertical roller 72 pivotally supported on the support bracket 71. The support bracket 71 is fixed to a notch-shaped recess 73 formed in the door frame 1, and extends toward the front 8 a (the mouth of the door 7) of the lock box 8 with respect to the bottom surface of the recess. Configured.

垂直ローラ７２はローラ垂直軸７４を介して支持ブラケット７１の先端に設けられている。前記支持ブラケット７１が固設される凹所４３は、受け部材２又は受け部材２とは別体の受け具の内部空間よりも深く、錠箱８のフロント８ａより離間した位置を底面とする形状に構成されるとともに、扉７の開放方向側が開口した形状とされ、建物の扉枠１としては、室外側に向かう段部のように形成される。 The vertical roller 72 is provided at the tip of the support bracket 71 via a roller vertical shaft 74. The recess 43 in which the support bracket 71 is fixed is shaped to have a bottom surface that is deeper than the inner space of the receiving member 2 or the receiving member separate from the receiving member 2 and away from the front 8 a of the lock box 8. In addition, the door 7 has a shape in which the opening direction side is open, and the door frame 1 of the building is formed like a stepped portion toward the outdoor side.

ところで、支持ブラケット７１に支持された垂直ローラ７２の位置は、例えば図４で示すように、フロント８ａ或いは摺動制御体６２の中心線「Ｏ」上ではなく、室内側、具体的には、スイング式押圧体６５の垂直軸６６側にやや偏芯する位置とされている。これに対して、前記スイング式押圧体６５の連結軸６４ｂは、前記中心線「Ｏ」よりも外側にやや偏芯する位置とされている。 Incidentally, the position of the vertical roller 72 supported by the support bracket 71 is not on the center line “O” of the front 8a or the sliding control body 62, as shown in FIG. The position is slightly eccentric to the vertical shaft 66 side of the swing type pressing body 65. On the other hand, the connecting shaft 64b of the swing-type pressing body 65 is at a position that is slightly eccentric to the outside of the center line “O”.

したがって、常態では、中心線「Ｏ」を挟んで、垂直ローラ７２とスイング式押圧体６５の前述した当接部と対向する側の縁辺ｂを有する垂直面側は所要間隔を有して対向している。 Therefore, in the normal state, the vertical surface side having the edge b on the side facing the abutting portion of the vertical roller 72 and the swing type pressing body 65 is opposed to the center line “O” with a required interval. ing.

（７）作用
図１６は、主要部の作用を示す各説明図である。前述したように、本実施形態では、レバーハンドル９、１１の軸部の作動突片（内端部）２３、３５がスライダー５２を上方向へ押圧する。 (7) Operation FIG. 16 is an explanatory diagram showing the operation of the main part. As described above, in this embodiment, the operating protrusions (inner end portions) 23 and 35 of the shaft portions of the lever handles 9 and 11 press the slider 52 upward.

したがって、例えば操作部材（９，１１）の握り部を、扉７の壁面に対して接離（図１の矢印Ａ）方向に押し、前記作動突片（内端部）２３、３５のいずれかが、錠箱８のフロント８ａ側に水平状態で位置変位（移動）すると、前記作動突片（内端部）共働レバー５３を介して摺動制御体６２の後端面を押圧する。 Therefore, for example, the grip portion of the operation member (9, 11) is pushed toward or away from the wall surface of the door 7 (arrow A in FIG. 1), and one of the operating protrusions (inner end portions) 23, 35 is pressed. However, when the position is displaced (moved) in a horizontal state toward the front 8 a side of the lock box 8, the rear end surface of the sliding control body 62 is pressed via the operating protrusion (inner end) cooperating lever 53.

そこで、例えば外側操作部材９の操作力により、作動突片（内端部）２３が可動すると、駆動部材５１を介して摺動制御体６２が、図１６で示すように、フロント８ａ側（矢印Ｂ方向）へ移動し続ける。スイング式押圧体６５は、その幅広後端部が中心線「Ｏ」よりも外側（室外）にやや偏芯する位置で摺動制御体６２の先端部の前面で押されることになるから、垂直軸６６を支点に、その係合突出先端部６５ｂが支持ブラケット７１の垂直ローラ７２に接近する方向へ水平回転し、かつ、該垂直ローラ７２にテコの原理（蹴り出し力）で圧接する。そして、該圧接力に基づく反力は全て扉自体を開く方向へ作用する。これにより、扉７の扉開閉端７ａと扉枠１との間に隙間が生じ、室内外の通気が行われて室内側の負圧がなくなり、室内が負圧となって開動に大きな力が必要となった扉７であっても、容易な開動が可能となる。 Therefore, for example, when the operating protrusion (inner end) 23 is moved by the operating force of the outer operating member 9, the sliding control body 62 is moved to the front 8a side (arrow) via the driving member 51 as shown in FIG. Continue to move in direction B). The swing-type pressing body 65 is pushed on the front surface of the front end portion of the sliding control body 62 at a position where the wide rear end portion is slightly eccentric to the outside (outdoor) from the center line “O”. With the shaft 66 as a fulcrum, the engagement protruding tip 65b rotates horizontally in a direction approaching the vertical roller 72 of the support bracket 71, and presses against the vertical roller 72 by the lever principle (kicking force). And all the reaction force based on this press-contact force acts in the direction which opens door itself. As a result, a gap is created between the door opening / closing end 7a of the door 7 and the door frame 1, the indoor and outdoor ventilation is performed, the negative pressure on the indoor side is eliminated, and the indoor becomes negative pressure, and a large force is exerted for opening. Even the door 7 that is required can be easily opened.
