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のハンドル装置は、扉１の開放端側に設けられるラッチ錠９と、扉内外の扉面に縦向き又は横向きにハンドルを取り付けるための座１２，１３と、この座のそれぞれに押し引き可能に保持されるハンドル１１ａ，１１と、ハンドルを押し引きの中間位置に保持するバネ１４，１４と、中間位置からのハンドルの押し操作ならびに引き操作によって、縦向きハンドルが取り付けられたときには縦向きハンドル用の操作部材２７を作動させ、横向きハンドルが取り付けられたときには横向きハンドル用の操作部材２８を作動させて、ラッチ錠９のラッチボルト１６の後退を許容させる作動機構１５，１５を設けている（符号は特許文献１に記載のもの）。   The handle device of Patent Document 1 includes a latch lock 9 provided on the open end side of the door 1, seats 12 and 13 for attaching the handle vertically or horizontally to the door surface inside and outside the door, and a push on each of the seats. Handles 11a, 11 that are held in a pullable manner, springs 14, 14 that hold the handle in an intermediate position of pushing and pulling, and when a vertical handle is attached by pushing and pulling the handle from the intermediate position, Operating mechanisms 15 and 15 are provided that operate the operating member 27 for the direction handle, operate the operating member 28 for the side handle when the side handle is attached, and allow the latch bolt 16 of the latch lock 9 to retract. (Reference numerals are those described in Patent Document 1).

この特許文献１のハンドル１１ａ，１１は、いわゆるプッシュ・プル式の操作部材であり、該操作部材の基端部には、錠箱内に突出する内外の作動片４５ａ、４５ｂが設けられている。これら内外の作動片４５ａ、４５ｂのいずれかが錠箱の上下方向（図３参照）又は左右方向（図１３参照）に移動すると、上下一対のラッチボルト規制部材（ロッキングピース）２２、２２がラッチボルト１６の規制を解く方向へ回転する。   The handles 11a and 11 of this Patent Document 1 are so-called push-pull type operation members, and inner and outer operation pieces 45a and 45b projecting into the lock box are provided at the base end of the operation members. . When any one of the inner and outer operating pieces 45a and 45b moves in the vertical direction (see FIG. 3) or the left and right direction (see FIG. 13) of the lock box, the pair of upper and lower latch bolt regulating members (locking pieces) 22 and 22 are latched. The bolt 16 rotates in the direction to release the restriction.

一方、特許文献２には、操作部材が、例えば操作軸を有するレバーハンドルであって、前記操作軸の回転によりラッチボルト（例えば棒状体のラッチボルト）が後退した後に、該操作軸のさらなる回転操作によって、「こじ開けラッチ８３」が扉枠側の当接部（反力部材）３９、１２１に扉をこじ開けるように圧接する事項（内外気圧差解消装置）が記載されている（符号は特許文献２に記載のもの）。   On the other hand, in Patent Document 2, the operation member is, for example, a lever handle having an operation shaft, and after the latch bolt (for example, a latch bolt of a rod-shaped body) is retracted by the rotation of the operation shaft, the operation shaft is further rotated. There is described a matter (internal and external pressure difference canceling device) in which the “peg opening latch 83” presses the door frame side contact portions (reaction force members) 39 and 121 so as to pry the door open. 2).

ところで、現在、内外気圧差解消装置を、特許文献１に記載のプッシュ・プル式の操作部材を備えたハンドル装置に合理的な構成（部品点数を少なくすること、各部材がスムースに作動すること等）を用いて適用することが求められている。なお、特許文献１、特許文献３乃至特許文献５には、反転ラッチ、反転ラッチを仮施錠するラッチ規制部材（ロッキングピース）が詳細に記載されている。これらの事項は、当業者によって自明事項である。   By the way, at present, the internal / external air pressure difference eliminating device has a rational configuration (to reduce the number of parts and each member operates smoothly) to the handle device having the push-pull type operation member described in Patent Document 1. Etc.). Note that Patent Document 1 and Patent Documents 3 to 5 describe inversion latches and latch restricting members (locking pieces) that temporarily lock the inversion latches. These matters are obvious to those skilled in the art.

（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９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 the restriction (locked state) from the latch restricting member is released by the operating force of the outer operation member 9, 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.

（３）各部材の具体的構成
まず、図４は本発明の第１実施形態の主要部を示す概略断面説明図である。また図６は、ラッチ規制部材４１及び駆動部材５１の駆動スライダー５２を示す分解斜視図。ここで、これらの図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、背景技術で説明したように、特許文献１、特許文献３乃至特許文献５には、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）４１が詳細に記載されており、これらの事項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、特許文献１、特許文献３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（実施例では上方支軸）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のアール部分４３ａを有する先端部が、駆動部材５１を構成する矩形ブロック形状の駆動スライダー５２の一側壁５２ａの上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) Specific Configuration of Each Member First, FIG. 4 is a schematic cross-sectional explanatory view showing the main part of the first embodiment of the present invention. FIG. 6 is an exploded perspective view showing the latch regulating member 41 and the drive slider 52 of the drive member 51. 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 these drawings. As described in the background art, Patent Document 1, Patent Document 3 to Patent Document 5 describe in detail a reverse latch as the latch member 11 and a latch restricting member (locking piece) 41 for temporarily locking the reverse latch 11. Since these are described and are obvious to those skilled in the art, a detailed description of the configuration is omitted here. The inversion latch 11 and the latch restricting member 41 are the same as in Patent Document 1, Patent Document 3, and the like, and are particularly different in that one of the latch restricting members 41 is more than the support shaft (upper support shaft in the embodiment) 42. The engagement arm 43 extends a predetermined amount in the direction of the rear wall 8 b of the lock box 8, and the distal end portion having the rounded portion 43 a of the engagement arm 43 constitutes a drive slider 51 having a rectangular block shape. It is a point which carries out sliding contact engagement with the protrusion-shaped locking part 52b provided in the upper end part of one side wall 52a. 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、例えば特許文献５（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, in FIG. 4 of Patent Document 5 (Japanese Patent Laid-Open No. 2001-225510). As described, only one side having the engagement 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.

次に図５は、図４における押圧部材用タイミングラグ手段５０を示す説明図である。また図７は、本実施例の駆動部材５１を示す分解斜視図である。これらの図を参照にして、押圧部材用タイミングラグ手段５０と駆動部材５１を説明する。本実施例の押圧部材用タイミングラグ手段５０は、駆動部材５１の駆動スライダー５２の下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延在する第１係合腕との間に設定された間隙である。   Next, FIG. 5 is an explanatory view showing the timing lug means 50 for the pressing member in FIG. FIG. 7 is an exploded perspective view showing the driving member 51 of this embodiment. The pressing member timing lag means 50 and the drive member 51 will be described with reference to these drawings. The timing lug means 50 for the pressing member of the present embodiment includes a lower end portion of a driving slider 52 of the driving member 51 and a first engagement arm extending from a shaft-supported portion of a crank-shaped or bifurcated cooperating lever 53. It is a gap set between

さて、本願発明の第１実施形態の駆動部材５１は、長孔を有するブロック形状に形成され、かつ、錠箱８の上下方向に移動する駆動スライダー５２と、該駆動スライダーに追動するように、かつ、該駆動スライダー５２から所定間隔離間した位置に存在する共働レバー用支軸５５に軸支された共働レバー５３と、押圧部材６１を初期位置へ戻す付勢手段６５とは別個であると共に、該付勢手段６５と共働して前記駆動スライダー５２を初期位置へと戻す駆動バネ５４とから成る。   The drive member 51 according to the first embodiment of the present invention is formed in a block shape having a long hole, and is driven so as to move in the vertical direction of the lock box 8 and the drive slider. In addition, the cooperating lever 53 that is pivotally supported by the cooperating lever support shaft 55 that is located at a predetermined distance from the drive slider 52 and the urging means 65 that returns the pressing member 61 to the initial position are separate. And a drive spring 54 that cooperates with the biasing means 65 to return the drive slider 52 to the initial position.

前述したように、図４は本発明の第１実施形態の主要部を示す説明図である。この図４に於いて、８は錠箱である。１１はラッチ部材の一例としての反転ラッチである。４１、４１は、例えば１組みのＬ型形状のロッキンクングピースで構成されたラッチ規制部材である。５２はラッチ規制部材の各支軸４２、或いはラッチ規制部材用復帰バネ４６、或いは又駆動レバー用支軸５５よりも錠箱の後壁側の内部空間に配設され、かつ、その長孔状の矩形開口５２ｃを形成する下方水内平面５２ｄに押圧係合する室外側作動突片２３並びに室内側作動突片３５（これらの位置は逆であっても良い）のいずれかの移動（本実施例では下降）によって位置変位するブロック状の駆動スライダーである。   As described above, FIG. 4 is an explanatory diagram showing the main part of the first embodiment of the present invention. In FIG. 4, 8 is a lock box. Reference numeral 11 denotes an inversion latch as an example of a latch member. Reference numerals 41 and 41 denote latch restricting members formed of, for example, a set of L-shaped locking pieces. 52 is disposed in the inner space on the rear wall side of the lock box with respect to the respective support shafts 42 of the latch restricting member, the return spring 46 for the latch restricting member, or the support shaft 55 for the drive lever, and has a long hole shape. Any one of the outdoor operation protrusion 23 and the indoor operation protrusion 35 that press-engage with the lower horizontal plane 52d forming the rectangular opening 52c (the positions may be reversed) (this embodiment) This is a block-shaped drive slider whose position is displaced by lowering in the example.

一方、５３は前述した一方のラッチ規制部材４１の支軸５５と押圧部材６１との間に固定的に設けられた横軸（支軸）５５に、その中央部に相当する部分が軸支され、かつ、少なくとも中央部（軸筒部）５３ａから延在する二本の係合腕５３ｂ、５３ｃが二股状に形成された共働レバーで、この実施例では、その第１係合腕５３ｂはラッチ部材１１の係止を解除した後に下降継続中の駆動スライダー５２の下端部のローラ５７が当る受け腕部分であり、これに対して第２係合腕５３ｃは押圧部材６１の押圧本体６２の後端部に切欠状に形成された傾斜状或いは垂直状の受け面６２ｄを押圧するカム腕部分である。該カム腕部分５３ｃは、いわば押圧部材６１の後端部の谷間の部分に入り込んでいる。   On the other hand, 53 is supported by a horizontal shaft (support shaft) 55 fixedly provided between the support shaft 55 and the pressing member 61 of one of the latch restricting members 41 described above, and a portion corresponding to the center portion thereof is supported by the shaft. In addition, in this embodiment, the first engagement arm 53b is a cooperating lever in which at least two engagement arms 53b and 53c extending from the central portion (shaft tube portion) 53a are formed in a bifurcated shape. This is a receiving arm portion with which the roller 57 at the lower end of the drive slider 52 continues to descend after the latch member 11 is released, and the second engaging arm 53c is against the pressing body 62 of the pressing member 61. The cam arm portion presses the inclined or vertical receiving surface 62d formed in a notch shape at the rear end. In other words, the cam arm portion 53 c enters the valley portion of the rear end portion of the pressing member 61.

さらに、５４は両端部が開く方向に作用する駆動バネで、例えばそのコイル状の中央部５４ａが共働レバー５３の軸筒部５３ａに巻装され、該中央部５４ａから延びる一端部５４ｃは前記共働レバー５３の第１係合腕５３ｂの一側面に設けたバネ端支持部５３ｄに支持されると共に、その他端部５４ｂは、駆動スライダー５２の下端部側（この実施例では、ローラ５７を支持する横軸５６）に圧接し、該駆動スライダー５２を前記共働レバー５３の第１係合腕５３ｂに対して所要量（ここでは間隙５０）浮かせる。もちろに、前記駆動バネ５４に代えて、例えば極性に対応して反発する一方の磁性体を共働レバー５３の第１係合腕５３ｂの先端部に設け、これに対して、駆動スライドのローラ５７を他方の磁性体に代えるとか、駆動スライドそのものを、反発機能を有する金属製にするとか、差圧機能を発揮させるために適宜に設計変更することもできる（均等範囲）。   Furthermore, 54 is a drive spring that acts in the direction in which both ends open, and for example, its coiled central part 54a is wound around the shaft cylinder part 53a of the cooperating lever 53, and one end part 54c extending from the central part 54a While being supported by a spring end support portion 53d provided on one side surface of the first engagement arm 53b of the cooperating lever 53, the other end portion 54b is on the lower end side of the drive slider 52 (in this embodiment, the roller 57 is The driving slider 52 is brought into pressure contact with the supporting horizontal shaft 56) and floats by a required amount (here, the gap 50) with respect to the first engaging arm 53 b of the cooperating lever 53. Of course, instead of the drive spring 54, for example, one magnetic body that repels in accordance with the polarity is provided at the tip of the first engagement arm 53b of the cooperating lever 53, and the drive slide 54 The roller 57 may be replaced with the other magnetic body, the drive slide itself may be made of metal having a repulsion function, or the design may be changed as appropriate in order to exhibit the differential pressure function (equal range).

次に図８は、駆動部材５１の共働レバー５３と駆動バネ５４、押圧部材６１を示す分解斜視図である。本実施例の押圧部材６１は、前記共働レバー５３の第２係合腕５３ｃに押される押圧本体６２と、該押圧本体６２の先端部に連係手段６４を介して連結されたスイング式押圧体６３とから成り、テコの原理を利用した前記スイング式押圧体６３を、扉枠１側の当接部７０に対して「蹴りだす様に」に作動させるので、扉を開け難いという問題点を解消することができる。   Next, FIG. 8 is an exploded perspective view showing the cooperative lever 53, the drive spring 54, and the pressing member 61 of the drive member 51. The pressing member 61 of the present embodiment includes a pressing main body 62 that is pressed by the second engaging arm 53c of the cooperating lever 53, and a swing type pressing body that is connected to the distal end portion of the pressing main body 62 via a linking means 64. 63, and the swing-type pressing body 63 using the lever principle is operated to “kick out” with respect to the contact portion 70 on the door frame 1 side, so that it is difficult to open the door. Can be resolved.

ここで、図８、図１１及び図１２を参照にして出力側の押圧部材６１の具体的構成を説明する。押圧部材６１を構成する押圧本体６２は、ラッチ部材１１と同一方向に進退するように錠箱８内の下方空間に配設されている。本実施例の押圧本体６２は、図８で示すように、全体として「ピストル形態」の印象を受けるブロック体であるが、その左右の垂直側面の中央部には、錠箱８側の被案内部分（例えば水平溝、水平切欠など）と係合する案内部分（例えば水平突起、複数の突起、突片等）６２ａが設けられている。これにより、押圧本体６２は安定した状態で進退動する。また、押圧本体６２は、その上壁は水平面となっているが、下壁は後壁に至る方向に適宜段差状に切欠され、その後端部に相当する切欠面には付勢手段６５の後端部を支持するバネ端支持突起６２ｂが設けられている。さらに、その前壁の中央部には連結突片６２ｃが設けられ、該連結突片６２ｃには、連係或いは連結手段６４を構成する連結軸６４ａが貫通する非真円の連結孔６４ｂが形成されている。   Here, a specific configuration of the pressing member 61 on the output side will be described with reference to FIGS. 8, 11, and 12. The pressing main body 62 constituting the pressing member 61 is disposed in the lower space in the lock box 8 so as to advance and retreat in the same direction as the latch member 11. As shown in FIG. 8, the pressing body 62 of the present embodiment is a block body that receives the impression of “pistol shape” as a whole, but at the center of the left and right vertical sides thereof, the guided body on the lock box 8 side is guided. A guide portion (for example, a horizontal protrusion, a plurality of protrusions, a protruding piece, or the like) 62a that engages with a portion (for example, a horizontal groove, a horizontal notch, or the like) is provided. Thereby, the press main body 62 moves forward and backward in a stable state. The pressing body 62 has a horizontal surface on the upper wall, but the lower wall is appropriately cut in a stepped direction in the direction to the rear wall, and the notch surface corresponding to the rear end portion has a rear surface of the urging means 65. A spring end support projection 62b that supports the end portion is provided. Further, a connecting protrusion 62c is provided at the center of the front wall, and a non-circular connecting hole 64b through which a connecting shaft 64a constituting the connecting or connecting means 64 passes is formed in the connecting protrusion 62c. ing.

次に、スイング式押圧体６３は、押圧本体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６７、６７を介して錠箱８内のフロント８ａ付近に軸支されている（図４参照）。   Next, the swing-type pressing body 63 is locked to the lock box 8 via the vertical shaft 66 and the upper and lower bearing members 67, 67 so as to be able to rotate a predetermined amount in the horizontal direction in cooperation with the forward and backward movement of the pressing body 62. It is pivotally supported near the front 8a (see FIG. 4).

このスイング式押圧体６３も前記押圧本体６２と同様にブロック体であるが、幅広後端部（内端部）は押圧本体６２の連結突片６２ｃを挟むことができる連結部分と成っていると共に、錠箱の扉の内壁面側の角部の上下壁には、垂直軸（本実施例では上下の垂直突起）６６、６６が設けられている。   The swing-type pressing body 63 is also a block body like the pressing main body 62, but the wide rear end portion (inner end portion) forms a connecting portion that can sandwich the connecting protrusion 62c of the pressing main body 62. Vertical shafts (upper and lower vertical protrusions in this embodiment) 66 and 66 are provided on the upper and lower walls at the corners on the inner wall surface side of the lock box door.

すなわち、本実施例では、前述したようにスイング式押圧体６３の幅広後端部６３ａは、押圧本体６２の先端部に連結軸６４ａを介して連結されることから、前記内端部に扉７を開放する室外側乃至押圧本体６２側を指向する所要幅の切欠凹所６８を形成し、この切欠凹所６８に押圧本体６２の連結突片６２ｃが嵌入した上で、前記内端部に形成した上下の連結孔６８と前記連結突片６２ｃの連結孔６４ｂに連結軸６４ａを差し込んで、両者６２、６３を一体的に連結している。連結突片６２ｃの連結孔６４ｂは非真円であることから、該非真円の連結孔６４ｂに連結軸６４ａに遊嵌合している。   That is, in the present embodiment, as described above, the wide rear end portion 63a of the swing type pressing body 63 is connected to the front end portion of the pressing body 62 via the connecting shaft 64a, so that the door 7 is connected to the inner end portion. A notch recess 68 having a required width directed to the outdoor side or the pressing main body 62 side is opened, and the connecting protrusion 62c of the pressing main body 62 is fitted into the notch recess 68 and then formed at the inner end portion. The connecting shaft 64a is inserted into the upper and lower connecting holes 68 and the connecting hole 64b of the connecting protrusion 62c to integrally connect the two 62 and 63 together. Since the connection hole 64b of the connection protrusion 62c is non-circular, it is loosely fitted to the connection shaft 64a in the non-circular connection hole 64b.

ここで、図１２の横断面を参照にすると、幅広後端部６３ａに所要幅の切欠凹所６８を形成することによって、該切欠凹所６８は、連結孔６９、６９を有する上下の水平支持面と、この水平支持面と交差する複数の垂直面を有し、前記垂直面は、一応、人差し指状の係合先端部６３ｂ側の垂直面と、垂直軸６６側の垂直面とに区分けすることができる。   Here, referring to the cross section of FIG. 12, by forming a notch recess 68 having a required width in the wide rear end portion 63a, the notch recess 68 has upper and lower horizontal supports having connecting holes 69, 69. And a plurality of vertical surfaces intersecting the horizontal support surface. The vertical surfaces are divided into a vertical surface on the index finger-like engagement tip 63b side and a vertical surface on the vertical shaft 66 side. be able to.

さらに、スイング式押圧体６３は、錠箱８内に垂直軸６６、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、角部を形成する後側の縁辺ａと、これに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。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垂直線と成り、さらに、前記扉枠側の当接部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、前述した人差し指状の先端部６３ｂは、錠箱８のフロント８ａから常に食み出している。なお、前述した下の軸受け部材６７、６７は、スイング式押圧体６３用の軸受け機能の他、連結突片６２ｃと対向する不番のバネ端支持部を有し、付勢手段６５の先端部を支持する機能も有する。   Further, when the swing-type pressing body 63 is pivotally supported in the lock box 8 via the vertical shafts 66 and 66, in a normal state where the operation member is not operated, the rear edge a that forms a corner portion, and The edge b on the side facing the abutting portion 70 on the orthogonal door frame side intersects the inner wall surface of the wide side wall of the lock box 8 at substantially equal angles (for example, 45 degrees). Further, an outdoor side edge c that intersects the rear side edge a is a vertical line that comes into contact with the inner wall surface of the wide side wall of the arc shape or the lock box 8, and further, on the side facing the contact part on the door frame side. The width of the edge b and the edge c of the outdoor side gradually becomes narrower as it reaches the vicinity of the tip. The index finger-shaped tip 63b described above always protrudes from the front 8a of the lock box 8. The lower bearing members 67, 67 described above have a bearing function for the swing-type pressing body 63, and an unnumbered spring end support portion that faces the connecting protrusion 62c. It also has a function of supporting

That is, FIG. 9 is an explanatory view in which either the inner or outer working piece (35, 23) has moved from the initial position and the latch restricting member 41 has rotated in a direction to release the restriction, and FIG. FIG. 11 is a diagram illustrating a state in which the driving slider 52 of the driving member 51 presses the cooperating lever 53 after unraveling. FIG. 11 shows the cooperating lever 53 rotating in the arrow direction (counterclockwise) to advance the pressing member 61. FIG. 12 is a schematic cross-sectional explanatory view of the main part (door frame side, door side) (the door side is the initial position), and FIG. 13 is an explanatory view showing the operation of the main part from a plan view using FIG. FIG. 14 and FIG. 14 are explanatory views in which the latch regulating member 41 and the driving slider 52 of the driving member 51, which are the main parts, return to their initial positions. As is apparent from these drawings, the internal / external air pressure difference canceling device of the present invention operates the internal / external operation of the drive slider 52 of the drive member 51 when any of the push / pull type internal / external operation members 9, 10 is operated. By either input of the inner and outer operating pieces 35 and 23 projecting into the lock box 8 of the members 9 and 10, the slide start is performed in the same direction as the operating pieces (35 and 23), whereby the latch lock of the latch member 11 is activated. After being unwound (after allowing the reversing latch to move), the synergistic lever 53 is caused to follow the driving slider 52 via the pressing member timing lag (delay) means 50, and the output is controlled by the driving member 51. The pressing member 61 on the side advances and presses against the pressing portion (reaction member) 70 on the door frame 1 side.

本実施例の当接部７０は、図１で示すように、少なくともラッチ受け穴４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。 (4) Contact portion 70 on the door frame side
Here, the contact portion 70 on the door frame side will be described with reference to FIGS. 1 and 12.
As shown in FIG. 1, the contact portion 70 of this embodiment is disposed on the back side (for example, Troyoke) of “a single strike plate” having at least the latch receiving hole 4. Depending on the case, the well-known strike plate or the like and the receiving device of the internal / external air pressure difference eliminating 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７３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。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７３は、錠受け２又は錠受け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 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 73. Configured as follows. The vertical roller 72 is provided at the tip of the support bracket 71 via a roller vertical shaft 74. The recess 73 to which the support bracket 71 is fixed is shaped to have a bottom surface that is deeper than the interior space of the lock receiver 2 or a separate holder from the lock receiver 2 and spaced 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、フロント８ａ或いは押圧本体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６３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６３の連結軸６４ａ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。   By the way, the position of the vertical roller 72 supported by the support bracket 71 is not on the front line 8a or the center line “O” of the pressing body 62, but on the indoor side, specifically, on the vertical shaft 66 side of the swing type pressing body 63. The position is slightly eccentric. On the other hand, the connecting shaft 64a of the swing-type pressing body 63 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、垂直ローラ用垂直軸７４とスイング式押圧体６３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。前述したように、開扉時、内外の操作手段９、１０のいずれかを操作すると、仮施錠機構を構成するラッチ規制板４１がラッチ部材の規制を解く方向へと回転し、その後瞬時に共働レバー５３が押圧本体６２の後端部側を押し付ける。この時スイング式押圧体６３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押圧本体６２の先端部で押されることになるから、上下の垂直軸６６、６６を支点に、その指先状の突出先端部６３ａ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。   Accordingly, in the normal state, the vertical surface side having the vertical axis 74 for the vertical roller and the edge b on the side facing the abutting portion of the swing type pressing body 63 with the center line “O” interposed therebetween has a required interval. Facing each other. As described above, when any one of the inner and outer operating means 9 and 10 is operated when the door is opened, the latch restricting plate 41 constituting the temporary locking mechanism rotates in a direction to release the restriction of the latch member, and then instantaneously co-rotates. The working lever 53 presses the rear end side of the pressing body 62. At this time, the swing-type pressing body 63 is pushed by the front end portion of the pressing 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 shafts 66 and 66 as fulcrums, the fingertip-shaped protruding tip 63a rotates horizontally in a direction approaching the vertical roller 72 of the support bracket 71, and presses against the vertical roller 72 on the principle of leverage. 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.

次に、図１５乃至図１９は、本発明の第２実施形態の各説明図である。この第２実施形態に用いた内外の操作手段もがプッシュ・プル方式のハンドルである。なお、この第２実施形態の説明に当って、第１実施形態と同一の部分には、同一又は同様の符号を付して重複する説明を割愛する。また、本発明のこのプッシュ・プル方式の内外のハンドル９、１０は、例えば一端部が台座に軸支された室外側のハンドルを扉の開く方向へ引く（プルする）際、又は／及び一端部が台座に軸支された室内側のハンドルを、扉の開く方向へ押す（プッシュする）際、それらの一端部の枢軸を支点に内外のハンドルが所定角度まで傾倒するハンドル揺動型のラッチ錠用ハンドル装置の構成部材であるが、もちろん、プッシュ・プル方式のハンドル装置は、平行リンク機構、同期機構等を用いたハンドル水平移動型であっても良い。   Next, FIGS. 15 to 19 are explanatory views of a second embodiment of the present invention. The internal and external operating means used in the second embodiment is also a push-pull type handle. In the description of the second embodiment, the same parts as those in the first embodiment are denoted by the same or similar reference numerals, and redundant descriptions are omitted. Further, the push / pull type inner and outer handles 9, 10 of the present invention have, for example, a case where an outdoor handle whose one end is pivotally supported by a pedestal is pulled (pulled) in the door opening direction and / or one end. A handle-swing type latch in which the handle on the inside and outside tilts to a specified angle with the pivot on one end as a fulcrum when pushing (pushing) the handle on the indoor side that is pivotally supported by the pedestal in the door opening direction Of course, the push-pull type handle device may be a handle horizontal movement type using a parallel link mechanism, a synchronization mechanism, or the like.

さて、図１９も、第１実施形態の図４と同様に室内外のハンドル装置を構成する操作部材側の内外の作動片３５、２３が同じ方向へ作動することを示す。   FIG. 19 also shows that the inner and outer operating pieces 35 and 23 on the operation member side that constitute the indoor / outdoor handle device operate in the same direction as in FIG. 4 of the first embodiment.

しかして、この第２実施形態が第１実施形態と主に異なる点は、第第１実施形態の押圧部材用タイミングラグ手段５０は、少なくとも駆動スライダー５２の下端部と共働レバー５３の軸支５５された部分から延在する第１係合腕５３ｂとの間に設定された間隙５０であるのに対して、この第２実施形態の押圧部材用タイミングラグ手段５０Ａは、一つの押圧部材６１Ａの後端部の傾斜状或いは垂直状の受け面６２ｄと駆動部材５１Ａを構成する共働レバー５３Ａを軸支された部分から垂直方向に延在する第２係合腕５３ｃとの間に設定された間隙５０Ａである点である。   Thus, the second embodiment is mainly different from the first embodiment in that the pressing member timing lag means 50 of the first embodiment is at least the lower end portion of the drive slider 52 and the shaft support of the cooperating lever 53. In contrast to the gap 50 set between the first engagement arm 53b extending from the 55 portion, the pressing member timing lag means 50A according to the second embodiment has one pressing member 61A. It is set between the inclined or vertical receiving surface 62d of the rear end portion and the second engagement arm 53c extending in the vertical direction from the portion where the cooperating lever 53A constituting the driving member 51A is pivotally supported. The gap is 50A.

付言すると、本発明の第２実施形態が本発明の第１実施形態と主に異なる事項は、（ａ）駆動部材５１Ａを構成する駆動スライダー５２Ａの形状が錠箱８Ａの後壁側に切欠を有するコ字形状或いはＬ字形状である点、（ｂ）錠箱８Ａの窓を介して該錠箱内に突出する内外の作動片３５，２３に対して所定間隔離間した位置に存在する支軸５５Ａが、前記作動片３５，２３よりも上方に配設されている点、（ｃ）共働レバー５３Ａの第１係合腕５３ｂがコ字形状の水平方向に折り曲げ形成された上方端板部分５２ｅの下面に係合する点、（ｄ）押圧本体６２を初期位置へ戻す付勢手段６５とは別個であると共に、該付勢手段と共働して前記駆動スライダー５２Ａを初期位置へと戻す駆動バネが存在しない点、（ｄ）共働レバー５３Ａの第１係合腕５３ｂと駆動スライダー５２Ａの上方端板部分５２ｅは、図１５の初期位置の状態に於いて、互いに接触状態である点、（ｅ）図１７で示すように、支軸５５Ａが駆動スライダー５２Ａの移動障害にならないように片持ち式で該共働レバー５３Ａの上端部側の中央部５３ａを軸支している点、（ｆ）共働レバー５３Ａの第２係合腕５３ｃの基端部寄りの部位にラッチ規制部材４１Ａの形成した小突起状の弧状係合部４３Ａと係合する不番の弧状押圧係止部が形成されている点等である。   In addition, the second embodiment of the present invention is mainly different from the first embodiment of the present invention in that (a) the shape of the drive slider 52A constituting the drive member 51A is notched on the rear wall side of the lock box 8A. A U-shaped or L-shaped point, and (b) a support shaft that is located at a predetermined distance from the inner and outer working pieces 35 and 23 protruding into the lock box through the window of the lock box 8A. 55A is disposed above the operating pieces 35 and 23, and (c) an upper end plate portion in which the first engaging arm 53b of the cooperating lever 53A is bent in a U-shaped horizontal direction. (D) Energizing means 65 for returning the pressing main body 62 to the initial position is different from that for engaging the lower surface of 52e, and cooperates with the urging means to return the drive slider 52A to the initial position. The point that there is no drive spring, (d) the first engagement of the cooperative lever 53A 53b and the upper end plate portion 52e of the drive slider 52A are in contact with each other in the initial position of FIG. 15, (e) as shown in FIG. 17, the support shaft 55A moves the drive slider 52A. The center portion 53a on the upper end portion side of the cooperating lever 53A is pivotally supported so as not to become an obstacle, and (f) near the base end portion of the second engaging arm 53c of the cooperating lever 53A. For example, an unnumbered arc-shaped pressing and engaging portion that engages with the small protrusion-shaped arc-shaped engaging portion 43A formed by the latch restricting member 41A is formed at the site.

この第２実施形態の前記（ｄ）の相違点に関して、共働レバー５３Ａは駆動スライダー５２Ａの下降移動に追動するものではなく、駆動スライダー５２Ａと共に同時に下降するものであるが、図１５の初期位置の状態に於いて、共働レバー５３Ａの長杆状の第２係合腕５３ｃの先端部と押圧部材６１の後端部の垂直端面との間にタイミングラグ５０Ａ（間隙）が設定されているから、差圧機構を発揮させることに関しては特に問題はない。   Regarding the difference (d) in the second embodiment, the cooperative lever 53A does not follow the downward movement of the drive slider 52A but descends simultaneously with the drive slider 52A. In the position state, a timing lag 50A (gap) is set between the front end portion of the elongated second engagement arm 53c of the cooperating lever 53A and the vertical end surface of the rear end portion of the pressing member 61. Therefore, there is no particular problem with regard to exerting the differential pressure mechanism.

もちろん、第１実施形態と実質的に同一になるように（共働レバー５３Ａが駆動スライダー５２Ａの下降移動に追動するように）、前記（ｄ）の係合関係について設計変更し、例えば図１５の初期位置の状態に於いて、共働レバー５３Ａの第１係合腕５３ｂと駆動スライダー５２Ａの上方端板部分５２ｅの間にタイミングラグ５０Ａ（間隙）を設定しても良い。その他、駆動スライダー５２Ａには錠箱に案内される図示しない複数個のガイドが設けられているが、ここでは細部的事項の図面や説明は割愛する。   Of course, the design of the engagement relationship of (d) is changed so that it is substantially the same as in the first embodiment (so that the cooperating lever 53A follows the downward movement of the drive slider 52A). In an initial position of 15, a timing lag 50A (gap) may be set between the first engagement arm 53b of the cooperating lever 53A and the upper end plate portion 52e of the drive slider 52A. In addition, the drive slider 52A is provided with a plurality of guides (not shown) that are guided by the lock box, but detailed drawings and explanations thereof are omitted here.

以上のように適宜設計変更しても、本発明の所期の目的・効果を達成することができる。
なお、本発明の各実施例に於いて、出力側の押圧部材６１、６１Ａの構成も新規事項であるが、該押圧部材６１、６１Ａの構成は発明の特定要件ではない。したがって、特許文献２に記載の「こじ開け型の押圧部材」も採用することができる。 Even if the design is appropriately changed as described above, the intended object and effect of the present invention can be achieved.
In addition, in each Example of this invention, although the structure of the output side pressing members 61 and 61A is also a new matter, the structure of these pressing members 61 and 61A is not a specific requirement of invention. Therefore, the “pick-up type pressing member” described in Patent Document 2 can also be employed.
