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はラッチ錠における内外気圧差解消装置に関するもので、例えば図７と共に、その段落００３７には、「こじ開けラッチ４４が進出され、こじ開けラッチ４４の傾斜面１０３が反力部材３９の角部１０９に摺接すると、こじ開けラッチ４４の傾斜面１０３が反力部材３９の角部１０９から扉７を開方向へこじる反力を受け、この反力が扉７を開放する方向（扉開動方向）の助勢力となる。つまり、ラッチボルト６５と同方向の移動動作から開動助勢力が分力として得られるようになる。このため、簡素かつ少ないスペースで、しかも、外部へ表出させることなく助勢力の発生機構が構成されている事項」が記載されている（符号は特許文献１のもの）。 Patent Document 1 relates to an internal / external air pressure difference eliminating device for a latch lock. For example, in FIG. 7 and paragraph 0037 thereof, in paragraph 0037, “a pry opening latch 44 is advanced, and an inclined surface 103 of the pry opening latch 44 is a corner portion of the reaction member 39. When slidably contacting 109, the inclined surface 103 of the pry opening latch 44 receives a reaction force that pricks the door 7 in the opening direction from the corner portion 109 of the reaction force member 39, and this reaction force opens the door 7 (door opening direction). In other words, the opening assist force can be obtained as a component force from the movement in the same direction as the latch bolt 65. Therefore, the assist force can be obtained in a simple and small space without being exposed to the outside. "Matters constituting power generation mechanism" are described (reference numerals are those of Patent Document 1).

また、特許文献２も、ラッチ錠における内外気圧差解消装置に関するものである。この特許文献２に記載の内外気圧差解消装置も、特許文献１と同様に「ラッチ形態の突出杆」がラッチボルト或いはデッドボルトと同一方向へ直進して、いわば「扉をこじ開けるようにして」、扉自体に開放方向の反力の一部（分力）を与えようとするものである。 Patent Document 2 also relates to an internal / external air pressure difference elimination device for a latch lock. Similarly to Patent Document 1, the internal / external air pressure difference eliminating device described in Patent Document 2 also moves straight in the same direction as the latch bolt or dead bolt, so to speak, “Let the door open”. A part of the reaction force in the opening direction (component force) is to be applied to the door itself.

ところで、特許文献３には、ラッチ錠を構成するラッチ部材の一例として「ラッチボルト」を用いたものが記載されている。このラッチ錠のラッチボルトは、操作部材の操作力により回転する駆動カム（リトラクタ）の駆動腕により、ラッチバネのバネ力に抗して錠箱内に後退可能である（周知乃至自明事項）。 By the way, in Patent Document 3, there is described one using a “latch bolt” as an example of a latch member constituting the latch lock. The latch bolt of the latch lock can be retracted into the lock box against the spring force of the latch spring by a drive arm of a drive cam (retractor) rotated by the operation force of the operation member (known or obvious matter).

また、特許文献４乃至特許文献６には、ラッチ錠を構成するラッチ部材の一例として「反転ラッチ」を用いたものが記載されている。これらの各特許文献には、基本的には「反転ラッチ」とプッシュ・プル式の操作部材の枢着基端部に設けられ、かつラッチ錠の錠箱に形成した窓を貫通する「作動突片」との間に、例えば該作動突片の位置変位によって回動する駆動カムと、該駆動カムと協働する連動機構を介して、又は連動機構を介さないで回転する単数又は複数のロッキングピースを介在させ、扉を開く際、前記プッシュ・プル式の操作部材を引く又は押すと、前記作動突片が水平方向又は垂直方向へ移動し、これにより前記駆動カムがラッチの仮施錠状態を解く方向へ所定量回転し、前記操作部材を把持した状態で扉を開くことができる（周知乃至自明事項）。 Patent Documents 4 to 6 describe one using a “reversed latch” as an example of a latch member constituting the latch lock. In each of these patent documents, an “operating protrusion” that basically is provided at the pivoted base end of an “inverted latch” and a push-pull type operating member and penetrates a window formed in the lock box of the latch lock. For example, a driving cam that is rotated by displacement of the position of the operating protrusion and a locking member or a plurality of locking members that rotate via an interlocking mechanism that cooperates with the driving cam or without an interlocking mechanism. When the push-pull type operating member is pulled or pushed when the piece is interposed and the door is opened, the operating protrusion moves in the horizontal direction or the vertical direction, so that the drive cam moves the temporary locking state of the latch. The door can be opened with a predetermined amount of rotation in the unwinding direction and holding the operation member (known or obvious matter).

（１）環境部材／本発明の前提要件
図１乃至図３を参照にして環境部材を説明する。なお、当業者にとって、デッドボルトの出没機構やラッチ部材に対する仮施錠用の係脱機構などの自明事項は省略し、本発明の主要部に絞って説明する。 (1) Environmental Member / Prerequisites of the Present Invention An environmental member will be described with reference to FIGS. For those skilled in the art, the obvious matters such as the dead bolt in / out mechanism and the engagement / disengagement mechanism for temporary locking with respect to the latch member are omitted, and only the main part of the present invention will be described.

まず、図１は戸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、上方から順番にデッド受け穴３、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を取付けるための切欠状の凹所がそれぞれ形成されている（後述）。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。 First, FIG. 1 is an environmental 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 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. In the lock receiver 2, a dead receiving hole 3, a latch receiving hole 4, and a notch portion 5 for a swing type pressing body are formed in this order from above. The vertical frame of the door frame 1 is formed with a notch-like recess for attaching the door stopper 6 and the lock receiver 2 (described later). 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、外側操作部材の一例としてのレバーハンドル９が設けられている。また、扉７の室外側に鍵孔が表れるシリンダ錠１０が設けられる。一方、扉７の室内側に内側操作部材の一例としてのレバーハンドル１１が設けられている。また、シリンダ錠１０の軸線上に位置するようにサムターン装置１２が設けられている。 As shown in FIG. 1, a lever handle 9 as an example of an outer operation member is provided 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). Further, a cylinder lock 10 in which a key hole appears on the outdoor side of the door 7 is provided. On the other hand, a lever handle 11 as an example of an inner operation member is provided on the indoor side of the door 7. A thumb turn device 12 is provided so as to be positioned on the axis of the cylinder lock 10.

そして、１３は例えば外側操作部材９の操作力によって後退動するラッチ部材（本実施例では、ラッチボルト）、１４は例えばシリンダ錠１０の鍵孔に差し込まれた合鍵の操作力によって後退動するデッドボルトである。なお、符号１５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１５は縦枠に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１５は発明の本質的事項ではない。 Reference numeral 13 denotes, for example, a latch member (in this embodiment, a latch bolt) that moves backward by the operating force of the outer operating member 9, and reference numeral 14 denotes a dead that moves backward by the operating force of the key combination inserted into the key hole of the cylinder lock 10, for example. It is a bolt. Reference numeral 15 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. This reinforcing piece 15 forms a notch recess in the vertical frame, so that it is reinforced. belongs to. The reinforcing piece 15 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.

（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。したがって、基本的には、操作手段の具体的態様、入力側の駆動手段（駆動カム）の具体的態様、錠前のラッチ機構の具体的態様を問わず、錠箱乃至扉側に、操作手段と、駆動カムと、摺動制御体と、単数又は複数の付勢手段と、テコの原理を応用したスイング式押圧体が設けられ、一方、扉枠側に前記スイング式押圧体の先端部（係合先端部）が圧接する当接部が存在すれば良い。 (2) Main part of this invention The internal / external air pressure difference elimination apparatus of this invention presupposes the latch lock X mentioned above. Therefore, basically, regardless of the specific mode of the operating means, the specific mode of the driving means (driving cam) on the input side, or the specific mode of the latch mechanism of the lock, the operating means , A drive cam, a sliding control body, one or a plurality of urging means, and a swing type pressing body applying the lever principle are provided, and on the other hand, the front end portion of the swing type pressing body (engagement) It is sufficient if there is an abutting portion where the joint tip portion is in pressure contact.

すなわち、例えば図２で示すように、本発明の内外気圧差解消装置は、ラッチ錠Ｘの錠箱８に、操作手段９、１１の操作力によって回転する駆動カム２１と、その後端部が該駆動カム２１の駆動腕２１ａと係合し、かつ該駆動腕２１ａの駆動力により錠箱８のフロント８ａ側へ付勢手段２３の付勢力に抗してスライドする摺動制御体２４と、この摺動制御体２４の先端部にその内端部が連結手段２５を介して連結されている共に、例えば角部に相当する中央部が前記錠箱８の扉の内壁面側の一側壁に垂直軸２６を介して軸支され、かつ、先端部側に前記フロント８ａ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２７を、それぞれ組み込み、開扉時、前記操作手段９、１１の操作力によって作動する前記駆動カム２１及び摺動制御体２４を介して前記スイング式押圧体２７が扉枠側の当接部２８に圧接すると、該圧接力は扉自体７を開く方向へ全て作用する。 That is, for example, as shown in FIG. 2, the internal / external air pressure difference elimination device of the present invention has a lock cam 8 of a latch lock X, a drive cam 21 that rotates by operating force of operating means 9, 11, and a rear end portion thereof. A sliding control body 24 that engages with the driving arm 21a of the driving cam 21 and slides against the urging force of the urging means 23 toward the front 8a side of the lock box 8 by the driving force of the driving arm 21a; The inner end portion of the sliding control body 24 is connected to the front end portion of the sliding control body 24 via the connecting means 25. For example, the central portion corresponding to the corner portion is perpendicular to the one side wall of the door of the lock box 8. Swing-type pressing bodies 27 that are pivotally supported via a shaft 26 and that have engaging tip portions that always protrude from the front 8a on the tip portion side are incorporated, respectively, and the operation means 9 and 11 are operated when the door is opened. The drive cam 21 and the sliding control body that are operated by force When 4 is the swing pressing member 27 via the pressure contact with the contact portion 28 of the door frame side, piezoelectric contact force acts all the direction of opening the door itself 7.

（３）各部材の具体的構成
例えば図２や図４を参照にして、発明の特定要件に関する各部材の具体的構成を説明する。まず、ラッチ部材１３の一例としてのラッチボルトの構成を説明する。ラッチ部材１３は、例えば外側操作部材９の握り部が水平状態の場合には、その後端部と錠箱８の後壁との間に存在するラッチバネ１７のバネ力により、係合先端部１３ａがフロント８ａから突出する。突出状態の係合先端部１３ａは、図２で示す手前側にラッチ受け穴４に係止される係止面を有し、該係止面の反対側（図２で示す向こう側）に摺接傾斜面を有する。 (3) Specific Configuration of Each Member The specific configuration of each member relating to the specific requirements of the invention will be described with reference to FIGS. 2 and 4, for example. First, a configuration of a latch bolt as an example of the latch member 13 will be described. For example, when the grip portion of the outer operation member 9 is in a horizontal state, the latch member 13 has the engagement tip portion 13a formed by the spring force of the latch spring 17 existing between the rear end portion and the rear wall of the lock box 8. Projects from the front 8a. The protruding engagement tip 13a has a locking surface that is locked to the latch receiving hole 4 on the front side shown in FIG. 2, and slides on the opposite side (the other side shown in FIG. 2) of the locking surface. It has a tangent surface.

また、係合先端部１３ａの後端面には棒状のラッチ杆１３ｂが一体的に設けられ、さらに、ラッチ杆１３ｂの後端部には所定長の係合後端部１３ｃが連設する。係合後端部１３ｃは、ラッチバネ１７を支持する端部に略垂直の受け面と、該受け面の下端から後方へ傾斜する逃がし用の下方傾斜面を有する左向台形形状の受け部１８を有する（公知事項）。 Further, a rod-shaped latch rod 13b is integrally provided on the rear end surface of the engagement tip portion 13a, and an engagement rear end portion 13c having a predetermined length is connected to the rear end portion of the latch rod 13b. The rear end 13c is a left trapezoidal receiving portion 18 having a receiving surface that is substantially perpendicular to the end that supports the latch spring 17 and a downward inclined surface that escapes backward from the lower end of the receiving surface. Have (known matter).

次に、駆動カム２１を説明する。駆動カム２１は、内外の操作部材の軸部を連結する角軸１９が貫通する不番の筒状部分と、この筒状部分から半径外方向に延在する長い駆動腕２１ａと、この駆動腕とは略反対方向に延在する短い駆動腕２１ｂとを有し、前記短い駆動腕２１ｂは、その先端面が緩やかな谷形状乃至弧状に切欠され、その後端部側の縁部で前述した台形形状の受け部１８を押し込んだ後に於いても、前記縁部が受け部１８の逃がし用の下方傾斜面の下方へと位置変位することができる（公知事項）。 Next, the drive cam 21 will be described. The drive cam 21 includes an unnumbered cylindrical portion through which the angular shaft 19 connecting the shaft portions of the inner and outer operation members passes, a long drive arm 21a extending radially outward from the cylindrical portion, and the drive arm. A short drive arm 21b extending in a direction substantially opposite to the trapezoidal shape. The short drive arm 21b has a tip surface cut into a gentle valley shape or arc shape, and the trapezoid described above at the edge on the rear end side. Even after the shaped receiving portion 18 is pushed in, the edge portion can be displaced to the lower side of the downward inclined surface for releasing the receiving portion 18 (known matter).

一方、前記長い駆動腕２１ａは、駆動カム２１が操作手段９、１１の操作力によって回転し、その結果、前述した係合先端部１３ａがラッチ受け穴４から外れる寸前乃至外れた瞬間（操作者はその瞬間扉を開けようとするが）、その指先状先端部分で摺動制御体２４の後端を付勢手段２３のバネ力に抗して押し出すことが可能である（図２の仮想線参照）。 On the other hand, in the long drive arm 21a, the drive cam 21 is rotated by the operation force of the operation means 9 and 11, and as a result, the moment immediately before the engagement tip 13a is released from the latch receiving hole 4 or the moment when it is released (operator 2), the rear end of the sliding control body 24 can be pushed out against the spring force of the urging means 23 at the tip of the fingertip (the phantom line in FIG. 2). reference).

次に、例えば図６や図７を参照にして、摺動制御体２４を説明する。摺動制御体２４は、ラッチ部材１３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。本実施例の摺動制御体２４は、図６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）２４ａが設けられている。これにより、摺動制御体２４は安定した状態で進退動する。また、摺動制御体２４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２３の後端部を支持するバネ端支持突起２４ｂ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２４ｃが設けられ、該連結突片２４ｃには、連結手段（連結軸）３１が貫通する非真円の連結孔３２が形成されている。 Next, the sliding control body 24 will be described with reference to FIGS. 6 and 7, for example. The sliding control body 24 is disposed in a lower space in the lock box 8 so as to advance and retreat in the same direction as the latch member 13. As shown in FIG. 6, the sliding control body 24 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, A guide portion (for example, a horizontal protrusion, a plurality of protrusions, a protruding piece, etc.) 24a that engages with a guided portion (for example, a horizontal groove, a horizontal notch, etc.) is provided. Thereby, the sliding control body 24 moves back and forth in a stable state. In addition, the sliding control body 24 has a horizontal surface on the upper wall, but the lower wall is appropriately cut out in a stepped direction in the direction reaching the rear wall, and the urging means 23 is provided on the notched surface corresponding to the rear end portion. A spring end support protrusion 24b is provided to support the rear end portion. Further, a connecting projection piece 24c is provided at the center of the front wall, and a non-circular connecting hole 32 through which the connecting means (connecting shaft) 31 passes is formed in the connecting projection piece 24c.

次に、スイング式押圧体２７を説明する。スイング式押圧体２７は、摺動制御体２４の進退動に追動あるいは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２６及び上下の軸受け部材３３、３３を介して錠箱８内のフロント８ａ付近に軸支されている。 Next, the swing type pressing body 27 will be described. The swing-type pressing body 27 is locked via the vertical shaft 26 and the upper and lower bearing members 33 and 33 so that it can be rotated by a predetermined amount in the horizontal direction following or cooperating with the forward and backward movement of the sliding control body 24. The box 8 is pivotally supported near the front 8a.

このスイング式押圧体２７も前記摺動制御体２４と同様にブロック体であるが、幅広後端部（内端部）２７ａは摺動制御体２４の連結突片２４ｃを挟むことができる連結部分２７ａ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）２６、２６を有している。 The swing-type pressing body 27 is also a block body like the sliding control body 24, but the wide rear end (inner end) 27a is a connecting portion that can sandwich the connecting protrusion 24c of the sliding control body 24. 27a, and vertical axes (up and down vertical protrusions in this embodiment) 26 and 26 are provided on the upper and lower walls of the corner 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２７の幅広後端部２７ａは、摺動制御体２４の先端部に連結軸３１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摺動制御体２４側を指向する所要幅の切欠凹所３５を形成し、この切欠凹所３５に摺動制御体２４の連結突片２４ｃが嵌入した上で、前記内端部に形成した上下の連結孔３６，３６と前記連結突片２４ｃの連結孔３２に連結軸３１を差し込んで、両者２４、２７を一体的に連結している。連結突片２４ｃの連結孔３２は非真円であることから、該非真円の連結孔３２に連結軸３１に遊嵌合している。 That is, in this embodiment, as described above, the wide rear end portion 27a of the swing-type pressing body 27 is connected to the front end portion of the sliding control body 24 via the connecting shaft 31, so that the inner end portion is connected to the inner end portion. A notch recess 35 having a required width directed to the outdoor side or the sliding control body 24 side that opens the door 7 is formed, and after the connecting projecting piece 24c of the sliding control body 24 is fitted into the notch recess 35, The connecting shaft 31 is inserted into the upper and lower connecting holes 36, 36 formed in the inner end portion and the connecting hole 32 of the connecting protrusion 24c, and the both 24, 27 are integrally connected. Since the connection hole 32 of the connection protrusion 24c is non-circular, the connection shaft 31 is loosely fitted into the non-circular connection hole 32.

ここで、図６の斜視図及び図７の横断面を参照にすると、幅広後端部２７ａに所要幅の切欠凹所３５を形成することによって、該切欠凹所３５は、連結孔３６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３８ａ、３８ｂを有し、前記垂直面３８ａ、３８ｂは、一応、人差し指状の先端部２７ｂ側の垂直面３８ａと、垂直軸３７側の垂直面３８ｂとに区分けすることができる。 Here, referring to the perspective view of FIG. 6 and the cross section of FIG. 7, the notch recess 35 having a required width is formed in the wide rear end portion 27 a, so that the notch recess 35 has a connecting hole 36. It has upper and lower horizontal support surfaces and a plurality of vertical surfaces 38a and 38b intersecting the horizontal support surfaces. The vertical surfaces 38a and 38b are, for the time being, a vertical surface 38a on the index finger-shaped tip 27b side and a vertical axis. It can be divided into a vertical surface 38b on the 37 side.

さらに、スイング式押圧体２７は、例えば図３で示すように、錠箱８内に垂直軸２６、２６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２７ｂは、錠箱８のフロント８ａから常に食み出している。 Further, as shown in FIG. 3, for example, when the swing-type pressing body 27 is pivotally supported in the lock box 8 via the vertical shafts 26 and 26, in a normal state in which the operation member is not operated, The side edge a and the side edge b opposite to the door frame side contact portion orthogonal to the side edge a intersect with the inner wall surface of the wide side wall of the lock box 8 at substantially equal angles (for example, 45 degrees each). doing. 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 portion 27 b described above always protrudes from the front 8 a of the lock box 8.

なお、前述した下の軸受け部材３３は、スイング式押圧体２７用の軸受け機能の他、連結突片２４ｃと対向する不番のバネ端支持部を有し、付勢手段２３の先端部を支持する機能も有する。 The lower bearing member 33 described above has a bearing function for the swing-type pressing body 27 and an unnumbered spring end support portion facing the connecting projection piece 24c, and supports the distal end portion of the biasing means 23. It also has a function to

（４）扉枠側の当接部
図８は、要部（扉枠側）の概略断面説明図、図９は正面視からの概略説明図、図１０は断面図である。これらの図を参照にして扉枠１側の当接部２８を説明する。本実施例では、当接部２８は、図１で示すように、デッド受け穴３及びラッチ受け穴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２８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 part on the door frame side FIG. 8 is a schematic cross-sectional explanatory view of a main part (door frame side), FIG. 9 is a schematic explanatory view from the front, and FIG. 10 is a cross-sectional view. The contact portion 28 on the door frame 1 side will be described with reference to these drawings. In this embodiment, as shown in FIG. 1, the abutting portion 28 is disposed on the back side (for example, Troyoke) of “a single strike plate” having the dead receiving hole 3 and the latch receiving hole 4. Of course, depending on the design, 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 28 may be formed separately.

さて、この当接部２８は、基本的には、錠受け２内に固定された支持ブラケット４１と、これに軸支された垂直ローラ４２とから成る。支持ブラケット４１は、扉枠１に形成された切欠状の凹所４３に固設され、この凹所４３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４２はローラ垂直軸４４を介して支持ブラケット４１の先端に設けられている。前記支持ブラケット４１が固設される凹所４３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 contact portion 28 basically includes a support bracket 41 fixed in the lock receiver 2 and a vertical roller 42 pivotally supported by the support bracket 41. The support bracket 41 is fixed to a notch-shaped recess 43 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 43. Configured as follows. The vertical roller 42 is provided at the tip of the support bracket 41 via a roller vertical shaft 44. The recess 43 to which the support bracket 41 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４１に支持された垂直ローラ４２の位置は、例えば図３で示すように、フロント８ａ或いは摺動制御体２４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２７の垂直軸２６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２７の連結軸３１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 42 supported by the support bracket 41 is not on the center line “O” of the front 8a or the sliding control body 24, for example, as shown in FIG. The position is slightly eccentric to the vertical shaft 26 side of the swing type pressing body 27. On the other hand, the connecting shaft 31 of the swing-type pressing body 27 is located at a position 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４２とスイング式押圧体２７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 42 and the swing type pressing body 27 is opposed to the center line “O” with a required interval. ing.

（５）主要部の作用
図１１乃至図１３は、主要部の作用を示す各説明図である。図２では、ダルマ２０及びデッドボルト１４を仮想線で概略的に示したが、前記デッドボルト１４は、周知のように、シリンダ錠１０が施錠状態の場合には、錠箱８のフロント８ａから突出する。また、操作部材の操作力により、ラッチボルト１３が前記フロント８ａから突出すると、図示しないラッチ規制手段（例えばラッチボルト１３をロックする仮施錠機構）により、該ラッチボルト１３は、その後退が阻止される。開扉時、普通一般に、操作手段を操作すると、前記仮施錠機構を構成するラッチ規制板やラッチ用のロックレバーが作動してラッチボルト１３の規制が解除される。 (5) Action of Main Part FIGS. 11 to 13 are explanatory diagrams showing the action of the main part. In FIG. 2, the dharma 20 and the dead bolt 14 are schematically shown by phantom lines. However, as is well known, the dead bolt 14 is removed from the front 8 a of the lock box 8 when the cylinder lock 10 is locked. Protruding. When the latch bolt 13 protrudes from the front 8a by the operating force of the operating member, the latch bolt 13 is prevented from retreating by a latch restricting means (not shown) (for example, a temporary locking mechanism that locks the latch bolt 13). The In general, when the operation means is operated when the door is opened, the latch restricting plate and the lock lever for latch that constitute the temporary locking mechanism are actuated to release the restriction of the latch bolt 13.

そこで、今仮に、図２で示す仮施錠状態から外側操作部材９を押し下げ、駆動カム２１が時計方向へ回転すると、図１１で示すように、駆動カム２１の短い駆動腕２１ｂの縁部がラッチボルト１３の後端部の係合部１８を押し付けるので、ラッチボルト１３は駆動カム２１の駆動力により、矢印で示すように錠箱８の後壁側へ後退する。そして、前記短い駆動腕２１ｂの縁部が前記係合部１８の下方に潜り込む寸前の所で、駆動カム２１の長い駆動腕２１ａの先端部分の前面が摺動制御体２４の後端面に当接する。 Therefore, if the outer operation member 9 is pushed down from the temporarily locked state shown in FIG. 2 and the drive cam 21 rotates in the clockwise direction, the edge of the short drive arm 21b of the drive cam 21 is latched as shown in FIG. Since the engaging portion 18 at the rear end of the bolt 13 is pressed, the latch bolt 13 is moved backward to the rear wall side of the lock box 8 as indicated by an arrow by the driving force of the driving cam 21. Then, the front surface of the distal end portion of the long drive arm 21 a of the drive cam 21 abuts against the rear end surface of the slide control body 24 at the point where the edge of the short drive arm 21 b is about to enter under the engaging portion 18. .

次いで、外側操作部材９の操作力により前記駆動カム２１がさらに時計方向に回転し続けると、図１２及び図１３で示すように、スイング式押圧体２７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２４の先端部で押されることになるから、上下の垂直軸２６、２６を支点に、その指先状の突出先端部２７ａが支持ブラケット４１の垂直ローラ４２に接近する方向へ水平回転し、かつ、該垂直ローラ４２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。 Next, when the driving cam 21 continues to rotate further clockwise by the operating force of the outer operating member 9, as shown in FIGS. 12 and 13, the swing-type pressing body 27 has a wide rear end at the center line “ Since it is pushed by the tip of the sliding control body 24 at a position slightly decentered to the outside (outdoor) of “O”, the fingertip-like protruding tip 27a is supported by the upper and lower vertical shafts 26, 26. Rotates horizontally in a direction approaching the vertical roller 42 of the support bracket 41, and presses against the vertical roller 42 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.

この欄では、本発明の他の実施形態を説明する（同一の構成部分には同一・同様の符号を付して重複する説明を割愛する）。第１実施形態に於いて、垂直軸２６はスイング式押圧体２７の角部に相当する中央部に設けられているが、角部に垂直軸２６を設けることや該垂直軸２６を可動軸にすること設計変更事項である。付言すると、垂直軸２６を角部からやや離れた位置に設け、或いは上下の軸受け部材３３、３３の各軸孔を長孔、楕円等に形状して垂直軸２６が多少位置変位するように、いわゆる権利範囲を回避するような設計変更をしたとしても、本発明の効果を得ることができる限り、これらの設計変更例は、本発明と実質的に同一である。 In this section, another embodiment of the present invention will be described (the same components are assigned the same / similar reference numerals and redundant descriptions are omitted). In the first embodiment, the vertical shaft 26 is provided at the central portion corresponding to the corner portion of the swing-type pressing body 27. However, the vertical shaft 26 is provided at the corner portion or the vertical shaft 26 is used as a movable shaft. What to do is a design change. In addition, the vertical shaft 26 is provided at a position slightly away from the corner portion, or the shaft holes of the upper and lower bearing members 33, 33 are formed into long holes, ellipses, etc., so that the vertical shaft 26 is slightly displaced. Even if a design change that avoids the so-called right range is made, these design change examples are substantially the same as the present invention as long as the effects of the present invention can be obtained.

また、第１の実施形態は、特許文献３と同様に、ラッチ錠を構成するラッチ部材１３の一例として「ラッチボルト」を用いたものである。これに対して、図１４は、ラッチ錠を構成するラッチ部材の一例として「反転ラッチ１３Ａ」を用いたものである（第２実施形態）。この反転ラッチ１３Ａと図示しない公知のプッシュ・プル式の操作部材とを組み合わせたラッチ錠Ｘ１の具体的構成は、特許文献４乃至特許文献６に見られるように、既に周知乃至自明事項なので、その詳細は割愛する。 The first embodiment uses a “latch bolt” as an example of the latch member 13 constituting the latch lock, as in Patent Document 3. On the other hand, FIG. 14 uses the “inverted latch 13A” as an example of a latch member constituting the latch lock (second embodiment). The specific configuration of the latch lock X1 combining this inversion latch 13A and a known push-pull type operation member (not shown) is already known or obvious as seen in Patent Documents 4 to 6, Details are omitted.

図１４に於いて、５１、５１は錠箱８Ａの側壁の上下に形成した窓、５２、５２はプッシュ・プル式の操作部材の枢着基端部に設けられ、かつ前記窓を貫通する上下の作動突片で、これらの上下の作動突片５２、５２は、駆動カム２１Ａの中心軸５３を基準にして点対象の上下の位置に存在し、水平方向に移動可能である。２１ａは摺動制御体２４の後端面を押し付ける駆動腕である。そして、５４は駆動カム２１Ａに連動するように組み合わせられた上下一対のロッキングピースである。 In FIG. 14, 51 and 51 are windows formed on the upper and lower sides of the side wall of the lock box 8A, and 52 and 52 are upper and lower windows provided at the pivot base end of the push-pull type operating member and penetrating the window. These upper and lower operating protrusions 52 and 52 are located at the upper and lower positions of the point target with respect to the central axis 53 of the drive cam 21A, and are movable in the horizontal direction. Reference numeral 21 a denotes a drive arm that presses the rear end face of the sliding control body 24. Reference numeral 54 denotes a pair of upper and lower locking pieces combined so as to be interlocked with the drive cam 21A.

この図１４の例示からも明らかなように、操作手段の具体的態様、入力側の駆動手段（駆動カム）の具体的態様、錠前のラッチ機構の具体的態様を問わず、錠箱乃至扉側に、レバー式、プッシュ・プル式等の操作手段（１９、１１）と、該操作手段の操作力によって所定方向へ回転する駆動カム（２１、２１Ａ）と、単数又は複数の付勢手段（２３）と、摺動制御体（２４）と、テコの原理を応用したスイング式押圧体（２７）が設けられ、一方、扉枠１側に前記スイング式押圧体の先端部（係合先端部）が圧接する当接部（２８）が存在すれば良い。なお、当接部（２８）の垂直ローラをスイング式押圧体の突出先端部に設け、一方、前記当接部を非回転式の受け面に設計変更する事項は、均等の範囲内である。 As is clear from the illustration of FIG. 14, the lock box or the door side regardless of the specific mode of the operating means, the specific mode of the input side drive means (drive cam), or the specific mode of the latch mechanism of the lock. In addition, operating means (19, 11) such as a lever type and push-pull type, a driving cam (21, 21A) rotating in a predetermined direction by an operating force of the operating means, and one or a plurality of urging means (23 ), A sliding control body (24), and a swing-type pressing body (27) applying the principle of leverage, on the other hand, the front end portion (engaging front end portion) of the swing-type pressing body on the door frame 1 side. It suffices if there is an abutting portion (28) that is in pressure contact. The matter that the vertical roller of the contact portion (28) is provided at the projecting tip of the swing type pressing body while the contact portion is designed to be a non-rotating receiving surface is within an equal range.

次に、図１５乃至図１７は第３実施形態を示す各説明図である。これらの図に於いて、第１実施形態と異なる点は摺動制御体２４Ａとスイング式押圧体２７Ａの組み合わせ構成である。第１実施形態では、摺動制御体２４の先端部に連結突片２４ｃが形成され、該連結突片２４ｃがスイング式押圧体２７の後端部に形成した切欠凹所３５に差し込まれた状態で連結手段３１を介して一体的に連結されているが、第３実施形態では、必ずしも「連結手段３１」を用いなくても良い旨を示している。 Next, FIGS. 15 to 17 are explanatory views showing a third embodiment. In these drawings, the difference from the first embodiment is the combined configuration of the sliding control body 24A and the swing type pressing body 27A. In the first embodiment, a connecting protrusion 24 c is formed at the tip of the sliding control body 24, and the connecting protrusion 24 c is inserted into a notch recess 35 formed at the rear end of the swing-type pressing body 27. However, the third embodiment shows that the “connecting means 31” is not necessarily used.

すなわち、第３実施形態では、摺動制御体２４Ａの先端部を「押圧先端部（係合先端部）２４ｃ」とし、一方、スイング式押圧体２７の後端部に形成した切欠凹所３５を「被係合部（押圧先端部に押される部位）」としている。なお、この第３実施形態では、望ましくは、スイング式押圧体２７Ａは垂直軸２６に巻装された復帰バネ２９により初期位置へ戻るように付勢されている。このように構成しても本発明の目的・効果を得ることができる。 That is, in the third embodiment, the front end portion of the sliding control body 24A is the “pressing front end portion (engaging front end portion) 24c”, while the notch recess 35 formed at the rear end portion of the swing type pressing body 27 is provided. The “engaged part (part pushed by the pressing tip)”. In the third embodiment, preferably, the swing type pressing body 27A is urged to return to the initial position by a return spring 29 wound around the vertical shaft 26. Even if comprised in this way, the objective and effect of this invention can be acquired.

次に、図１８は本発明の第４実施形態を示す説明図である。この第４実施形態が第１実施形態（図２、図４）と主に異なる点は、駆動カム２１Ｂと摺動制御体２４Ｂとの係合である。すなわち、２１Ｂは第１実施形態の長い駆動腕（係合腕）に相当するピニオン部分で、該ピニオン部分２１ａは、駆動カム２１Ｂの外周部の一部に設けられている。一方、２４ｄは摺動制御体２４Ｂの中央部乃至後端部の上面に突設され、前記ピニオン部分２１ａと係合（噛合）するラックである。 Next, FIG. 18 is explanatory drawing which shows 4th Embodiment of this invention. The fourth embodiment is mainly different from the first embodiment (FIGS. 2 and 4) in the engagement between the drive cam 21B and the slide control body 24B. That is, 21B is a pinion portion corresponding to the long drive arm (engagement arm) of the first embodiment, and the pinion portion 21a is provided at a part of the outer peripheral portion of the drive cam 21B. On the other hand, 24d is a rack that protrudes from the upper surface of the center part to the rear end part of the sliding control body 24B and engages (meshes) with the pinion part 21a.

この様に、駆動カム２１Ｂと摺動制御体２４Ｂとの係合を、ピニオンとラックに置換しても、第１実施形態と同一の目的を達成することができる。したがって、特に図示しないが、係合構造をクランクとレバーの組合せにしても、同様の目的を達成することができる。 As described above, even if the engagement between the drive cam 21B and the sliding control body 24B is replaced with the pinion and the rack, the same object as that of the first embodiment can be achieved. Therefore, although not shown in particular, the same object can be achieved even if the engagement structure is a combination of a crank and a lever.

次に、図１９は本発明の第５実施形態を示す説明図である。この第５実施形態が第１実施形態と主に異なる点は、図１４の第２実施形態と同様に、（ａ）ラッチ錠を構成するラッチ部材の一例として「反転ラッチ１３Ａ」を用いた点、（ｂ）例えば実公平３−６７７３号記載のラッチ錠と同様の構成を、本発明の主要部に加味した点である。 Next, FIG. 19 is explanatory drawing which shows 5th Embodiment of this invention. The fifth embodiment is mainly different from the first embodiment in that, similarly to the second embodiment of FIG. 14, (a) “inverted latch 13A” is used as an example of a latch member constituting the latch lock. (B) For example, the same structure as the latch lock described in Japanese Utility Model Publication No. 3-6773 is added to the main part of the present invention.

なお、実公平３−６７７３号に記載のラッチ錠の構成は、反転ラッチ用のロッキングピースの垂直部分が、互いに逆方向へ水平移動する作動板のいずれかに押されても、一対の前記ロッキングピースが同時に対称的に反転するものであるが、該仮施錠機構は周知事項であると共に、ラッチ部材１３Ａ用の仮施錠機構は本発明の限定要件ではないので、ここでは詳細な説明を割愛する。 Note that the structure of the latch lock described in Japanese Utility Model Publication No. 3-6773 is such that even if the vertical portion of the locking piece for the inversion latch is pushed by either of the operating plates that move horizontally in the opposite directions, Although the pieces are symmetrically reversed at the same time, the temporary locking mechanism is a well-known matter, and the temporary locking mechanism for the latch member 13A is not a limiting requirement of the present invention, so detailed description is omitted here. .

しかしながら、ラッチ部材１３Ａが反転ラッチの場合には、ラッチ錠は、望ましくは、プッシュ・プル式の操作部材を操作して前記反転ラッチ用のロッキングピース５４の仮施錠を解きながら、扉の引き離し機構（ラッチ錠用の内外気圧差解消装置）を作動させるので、念のために反転ラッチ用の仮施錠機構を簡単に説明する。 However, when the latch member 13A is an inversion latch, the latch lock is preferably a door pulling mechanism while operating the push-pull type operation member to unlock the locking piece 54 for the inversion latch. Since the (internal / external pressure difference eliminating device for latch lock) is operated, the temporary locking mechanism for the reverse latch will be briefly described just in case.

しかして、符号５１は錠箱８Ａの側壁の上部に形成した窓である。５２、５２はプッシュ・プル式の操作部材の枢着基端部に設けられ、かつ前記窓５１を貫通する上下の作動突片で、これらの上下の作動突片５２、５２は、仮施錠機構を構成する駆動カム２１Ａの中心軸５３を基準にして、駆動カム２１Ａの上方係合腕の方に存在し、プッシュ・プル式の操作部材の操作に対応して互いに異なる方向に移動可能である。また２１ａは摺動制御体２４の後端面を押し付ける駆動カム２１Ａの駆動腕である。５４は駆動カム２１Ａに連動する上下一対のロッキングピースである（図１４と同様）。 Thus, reference numeral 51 denotes a window formed in the upper part of the side wall of the lock box 8A. 52 and 52 are upper and lower operating protrusions provided at the pivot base end portion of the push-pull type operating member and penetrating the window 51. These upper and lower operating protrusions 52 and 52 are temporary locking mechanisms. Referring to the central axis 53 of the drive cam 21A that constitutes the drive cam 21A, the drive cam 21A is located on the upper engagement arm and can be moved in different directions corresponding to the operation of the push-pull type operation member. . Reference numeral 21a denotes a driving arm of a driving cam 21A that presses the rear end surface of the sliding control body 24. Reference numeral 54 denotes a pair of upper and lower locking pieces interlocking with the drive cam 21A (similar to FIG. 14).

図２０及び図２１は、本発明の第６実施形態を示す各説明図である。この第６実施形態が第１実施形態（図２、図４）と主に異なる点は、次の通りである。
（ａ）ラッチ錠用の内外気圧差解消装置、すなわち、開扉時における扉の引き離し機構は、ラッチ部材１３よりも上方に配設されている点。
（ｂ）内外気圧差解消装置を構成する摺動制御体２４Ｂは、バネ受け後端部２４ｅが、やや下方に突出状に延在し、駆動カム２１Ｂの駆動腕２１ａを受ける係合受け部の機能を有する点。
（ｃ）前記摺動制御体２４Ｂを所定方向に付勢する付勢手段２３Ｂが、摺動制御体２４Ｂのバネ受け後端部２４ｅと錠箱８Ｂの後壁８ｂの間に設けられている点。付言すると、付勢手段２３Ｂは、摺動制御体２４Ｂ及びスイング式押圧体２７Ｂを、錠箱８Ｂのフロント８ａから突出方向へと付勢している点。
（ｄ）初期位置に於いて、スイング式押圧体２７Ｂの係合先端部２７ｂの突出量が大きい点。
（ｅ）図２１と図１３の作用を比較すると明らかなように、逆パターン（スイング式押圧体２７Ｂが回転しながら後退する方式）である点。すなわち、開扉時、駆動カム２１Ｂの駆動腕２１ａが摺動制御体２４Ｂのバネ受け後端部２４ｅに当り、摺動制御体２４Ｂが駆動カム２１Ｂのさらなる回転により、付勢手段２３Ｂのバネ力に抗して錠箱８Ｂの後壁８ｂ側に後退すると、該摺動制御体２４Ｂはスイング式押圧体２７Ｂを引っ張ることになり、その結果、スイング式押圧体２７Ｂは垂直軸２６を支点にして矢印Ａ方向へと回転して、その係合先端部２７ｂが当接部２８に衝突する。 20 and 21 are explanatory views showing a sixth embodiment of the present invention. The sixth embodiment is mainly different from the first embodiment (FIGS. 2 and 4) as follows.
(A) The internal / external air pressure difference eliminating device for the latch lock, that is, the door pulling-off mechanism when the door is opened is disposed above the latch member 13.
(B) The sliding control body 24B that constitutes the internal / external air pressure difference elimination device has an engagement receiving portion that has a spring receiving rear end portion 24e that extends slightly downward and receives the driving arm 21a of the driving cam 21B. It has a function.
(C) The biasing means 23B for biasing the sliding control body 24B in a predetermined direction is provided between the spring receiving rear end 24e of the sliding control body 24B and the rear wall 8b of the lock box 8B. . In other words, the urging means 23B urges the sliding control body 24B and the swing type pressing body 27B in the protruding direction from the front 8a of the lock box 8B.
(D) At the initial position, the protrusion amount of the engaging tip portion 27b of the swing type pressing body 27B is large.
(E) The point is a reverse pattern (a method in which the swing-type pressing body 27B moves backward while rotating), as is apparent from a comparison of the actions of FIG. 21 and FIG. That is, when the door is opened, the drive arm 21a of the drive cam 21B hits the spring receiving rear end 24e of the slide control body 24B, and the slide control body 24B further rotates the drive cam 21B, thereby causing the spring force of the biasing means 23B. If the sliding control body 24B retracts to the rear wall 8b side against the lock box 8B, the swinging pressure body 27B pulls the swinging pressure body 27B. As a result, the swinging pressure body 27B uses the vertical shaft 26 as a fulcrum. Rotating in the direction of arrow A, the engagement tip portion 27 b collides with the contact portion 28.

最後に、図２２は本発明の第７実施形態を示す説明図である。この第７実施形態は、図１４の第２実施形態の付勢手段２３の付勢方向を逆にしたパターン（スイング式押圧体２７Ｃが回転しながら後退する方式）である。つまり、第６実施形態の逆パターンを図１４の第２実施形態に応用したものである。 Finally, FIG. 22 is an explanatory view showing a seventh embodiment of the present invention. The seventh embodiment is a pattern in which the urging direction of the urging means 23 of the second embodiment of FIG. 14 is reversed (a method in which the swing type pressing body 27C moves backward while rotating). That is, the reverse pattern of the sixth embodiment is applied to the second embodiment of FIG.

したがって、摺動制御体２４Ｃ用付勢手段２３Ｃは、第６実施形態と同様に摺動制御体２４Ｃのバネ受け後端部２４ｅと錠箱８Ｃの後壁８ｂの間に設けられている点、付勢手段２３Ｃは、摺動制御体２４Ｃ及びスイング式押圧体２７Ｃを、錠箱８Ｃのフロント８ａから突出方向へと付勢している点、及び内外気圧差解消装置の作用は第６実施形態と全く同じである（図１３の説明を援用する）。 Therefore, the urging means 23C for the sliding control body 24C is provided between the spring receiving rear end 24e of the sliding control body 24C and the rear wall 8b of the lock box 8C, as in the sixth embodiment. The biasing means 23C biases the sliding control body 24C and the swing-type pressing body 27C in the protruding direction from the front 8a of the lock box 8C, and the operation of the internal / external air pressure difference elimination device is the sixth embodiment. Is exactly the same (the description of FIG. 13 is used).

以上の様に構成しても、第１実施形態と同様に、スイング式押圧体の係合先端部の圧接力は、特許文献１等のような「直進方向に対する分力」とは成らず、略全て扉を開く方向に作用する反力と成るので、扉枠側の当接部に対するスイング式押圧体の圧接力を十分に発揮することができる。 Even when configured as described above, as in the first embodiment, the pressure contact force of the engagement tip of the swing-type pressing body does not become a “component force in the straight direction” as in Patent Document 1, etc. Since almost all of the reaction forces act in the direction of opening the door, the pressure contact force of the swing-type pressing body against the contact portion on the door frame side can be sufficiently exerted.
