Description

本発明は、扉枠と扉を連結アームで開閉自在に連結する隠し蝶番の構造に関するもので、詳しくは、連結アームがスライドするためのガイドレールを調整ブロックに容易に形成できる隠し蝶番の構造の技術に関する。   The present invention relates to a structure of a concealed hinge in which a door frame and a door are connected with a connecting arm so as to be opened and closed. Specifically, the structure of the concealed hinge that can easily form a guide rail for sliding the connecting arm on an adjustment block. Regarding technology.

従来、隠し蝶番として特許文献１の記載が知られている。特許文献１によれば図８に示すように、隠し蝶番４０は、扉枠４１と扉４２を開閉自在に連結する二組の連結アーム４３が一対の調整ブロック４７、４７に取付けられる。調整ブロック４７、４７は扉枠４１と扉４２にそれぞれ形成された収容部４１ａ、４２ａに一対のケーシング４４、４５を介して固定ネジ５０によって固定される。   Conventionally, the description of Patent Document 1 is known as a hidden hinge. According to Patent Document 1, as shown in FIG. 8, the hidden hinge 40 has two sets of connecting arms 43 that connect the door frame 41 and the door 42 so as to be freely opened and closed, and are attached to a pair of adjustment blocks 47 and 47. The adjustment blocks 47 and 47 are fixed to the accommodating portions 41a and 42a formed in the door frame 41 and the door 42 by a fixing screw 50 via a pair of casings 44 and 45, respectively.

前記各連結アーム４３は、左右で対をなす平面視概略「Ｃ」もしくは「く」の字状の同一構成のリンク部材で、上下方向に位置をずらして垂直回転軸４６で回転可能にヒンジ結合される。   Each of the connecting arms 43 is a link member having the same configuration having a substantially “C” or “<” shape in plan view, which is paired on the left and right sides, and is hinged so as to be able to rotate around the vertical rotation shaft 46 while shifting the position in the vertical direction. Is done.

前記連結アーム４３の一端は図示しないピン支持部で回転可能とするとともに、他端４８は図示しないスライド軸がその上下端部を調整ブロック４７に設けられる凹溝レール部４９内でスライド移動することにより扉４２を開閉することができる。   One end of the connecting arm 43 can be rotated by a pin support portion (not shown), and the other end 48 is slidably moved by a slide shaft (not shown) at the upper and lower end portions thereof in a concave groove rail portion 49 provided in the adjustment block 47. Thus, the door 42 can be opened and closed.

ここで、収容部４１ａ、４２ａの奥行きに制限がある場合には、凹溝レール部４９を水平面内で傾けることによって実質的に凹溝レール部４９の奥行き長さを短くする必要があった。
特開平０６−２８８１３９号公報 Here, when the depths of the accommodating portions 41a and 42a are limited, it is necessary to substantially shorten the depth length of the concave groove rail portion 49 by tilting the concave groove rail portion 49 in the horizontal plane.
Japanese Patent Laid-Open No. 06-288139

ところが、凹溝レール部４９を水平面内で傾けると、ダイカスト鋳造によって調整ブロック４７を形成する場合に、鋳込んだ後に可動型を引抜くことができないためダイカスト鋳造ができないという問題があった。   However, if the grooved rail portion 49 is tilted in a horizontal plane, there is a problem that when the adjustment block 47 is formed by die casting, the die cannot be cast because the movable die cannot be pulled out after casting.

そこで、本発明はかかる従来技術の問題に鑑みなされたものであって、水平面内で傾きを持つ凹溝レール部を調整ブロックに容易に形成できるダイカスト鋳造による隠し蝶番の構造を提供することを目的とする。   Therefore, the present invention has been made in view of the problems of the prior art, and an object of the present invention is to provide a structure of a hidden hinge by die casting that can easily form a concave groove rail portion having an inclination in a horizontal plane in an adjustment block. And

請求項１の発明は、扉枠と扉を開閉自在に連結する二組の連結アームが垂直回転軸を中心に回転可能に連結されて一対の調整ブロックに取付けられ、前記連結アームは一端がピン支持部で他端がスライド支持部であり、前記二組の連結アームのそれぞれのピン支持部とスライド支持部を一対として取付けられた前記各調整ブロックを一対の蝶番ケーシングに組込んで扉枠と扉に設けた収容部に取付けて成る隠し蝶番であって、前記スライド支持部は前記連結アームに備えるスライド軸とこのスライド軸の上下端部をスライド可能に支えるため前記調整ブロックに備える一対のガイドレールとから成り、このガイドレールは前記調整ブロックとは別体の直方体形状のガイド本体に凹溝レール部を抉って形成され、前記ガイド本体が前記調整ブロックの露出側表面に対して垂直に取付けられるとともに前記凹溝レール部が前記ガイド本体の長軸に対して水平面内で傾斜して形成されることを特徴としている。   According to the first aspect of the present invention, two sets of connecting arms for connecting the door frame and the door so as to be openable and closable are connected to a pair of adjustment blocks so as to be rotatable about a vertical rotation axis, and one end of the connecting arm is pinned. The other end of the support portion is a slide support portion, and each of the adjustment blocks attached as a pair of the pin support portion and the slide support portion of each of the two sets of connecting arms is incorporated into a pair of hinge casings and a door frame. A concealed hinge that is attached to a receiving portion provided on a door, wherein the slide support portion includes a slide shaft provided in the connecting arm and a pair of guides provided in the adjustment block for slidably supporting upper and lower ends of the slide shaft. The guide rail is formed of a rectangular parallelepiped guide body that is separate from the adjustment block, with the grooved rail portion interposed between the guide block and the adjustment block. The groove rail section with mounted perpendicular to the exposed surface of the click is being formed to be inclined in a horizontal plane relative to the longitudinal axis of the guide body.

請求項２の発明は、請求項１記載の隠し蝶番の構造であって、前記調整ブロックに孔部を形成するとともにこの孔部に挿入されるコ字状ブロックを前記ガイド本体に形成し、前記コ字状ブロックの両側面に前記孔部と係止する係止部を備えることを特徴としている。   The invention of claim 2 is the structure of the hidden hinge according to claim 1, wherein a hole is formed in the adjustment block and a U-shaped block inserted into the hole is formed in the guide body. The both sides of the U-shaped block are provided with locking portions that lock with the hole.

請求項１記載の発明によれば、扉枠と扉を開閉自在に連結する二組の連結アームの他端がスライド支持部であり、前記スライド支持部は前記連結アームに備えるスライド軸とこのスライド軸の上下端部をスライド可能に支えるため前記調整ブロックに備える一対のガイドレールとから成り、このガイドレールは前記調整ブロックとは別体の直方体形状のガイド本体に凹溝レール部を抉って形成される。   According to the first aspect of the present invention, the other ends of the two sets of connecting arms that connect the door frame and the door so as to be openable and closable are the slide support portions, and the slide support portions include the slide shaft provided in the connection arms and the slide. It consists of a pair of guide rails provided in the adjustment block to support the upper and lower ends of the shaft in a slidable manner, and this guide rail is formed by sandwiching a groove groove on a rectangular parallelepiped guide body separate from the adjustment block Is done.

このため、前記ガイド本体は前記調整ブロックの露出側表面に対して垂直に取付けることができるのでダイカスト鋳造が容易にできる。また、凹溝レール部自体は別体のガイド本体を抉って水平面内で傾きを持って形成できるので、前記扉枠と扉の収容部の奥行きに制限があっても凹溝レール部の必要長さを確保することができる。   For this reason, since the guide body can be mounted perpendicularly to the exposed side surface of the adjustment block, die casting can be easily performed. In addition, since the grooved rail part itself can be formed with a tilt in a horizontal plane by rolling a separate guide body, the required length of the grooved rail part is limited even if the depth of the door frame and the door accommodating part is limited. Can be secured.

請求項２記載の発明によれば、前記ガイド本体に形成されるコ字状ブロックを前記調整ブロックの孔部に挿入するだけで、前記コ字状ブロックの両側面に備える係止部が前記孔部の縁部に係止されるので、確実且つ容易に前記ガイド本体を前記調整ブロックに取付けることができる。   According to the second aspect of the present invention, simply by inserting the U-shaped block formed on the guide body into the hole portion of the adjustment block, the locking portions provided on both side surfaces of the U-shaped block are the holes. The guide body can be securely and easily attached to the adjustment block.

＜本発明の実施形態＞
以下に、本発明の実施形態を図１〜図７に基づいて説明する。 <Embodiment of the present invention>
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

＜隠し蝶番の構造の構成＞
図１（ａ）、（ｂ）に示すように、本発明の実施形態における隠し蝶番１の構造は、扉枠２と扉３を開閉自在に連結する断面「Ｃ」字状の二組の連結アーム４ａ、４ｂが垂直回転軸５に連結されて一対の扉枠２用の調整ブロック６ａと扉３用の調整ブロック６ｂに収納される。連結アーム４ａ、４ｂはそれぞれ一端Ｓにピン支持部としての回転軸７を備え、他端Ｔにスライド支持部Ｑを備える。 <Structure of hidden hinge structure>
As shown in FIGS. 1 (a) and 1 (b), the structure of the hidden hinge 1 in the embodiment of the present invention is a combination of two sets of “C” -shaped cross sections that connect the door frame 2 and the door 3 so as to be freely opened and closed. The arms 4 a and 4 b are connected to the vertical rotation shaft 5 and are accommodated in a pair of adjustment blocks 6 a for the door frame 2 and an adjustment block 6 b for the door 3. Each of the connecting arms 4a and 4b includes a rotation shaft 7 as a pin support portion at one end S and a slide support portion Q at the other end T.

いま、扉３が全開した状態で、調整ブロック６ａ、６ｂに向かって左右方向をＸ軸、上下（垂直）方向をＹ軸とし、Ｘ軸とＹ軸に垂直な軸をＺ軸（正面方向）とする。   Now, with the door 3 fully opened, the left and right directions are the X axis, the vertical (vertical) direction is the Y axis, and the axes perpendicular to the X and Y axes are the Z axis (front direction) toward the adjustment blocks 6a and 6b. And

スライド支持部Ｑは、連結アーム４ａ、４ｂに回転可能に取付けられるスライド軸８と、このスライド軸８の上下端部をスライド可能に支えるために調整ブロック６ａ、６ｂの上下端部に備える一対のスライドレール１３、１４とから成る
各調整ブロック６ａ、６ｂには、二組の連結アーム４ａ、４ｂのそれぞれの回転軸７とスライド軸８が一対で取付けられる。そして、一対の調整ブロック６ａ、６ｂは一対の蝶番ケーシング１ａ、１ｂにそれぞれ組込まれて、扉枠２と扉３に設ける収容部２ａ、３ａに取付けられる。 The slide support portion Q is a pair of slide shafts 8 that are rotatably attached to the connecting arms 4a and 4b, and a pair of adjustment blocks 6a and 6b that are provided at the upper and lower ends of the slide shaft 8 so as to be slidable. A pair of rotating shafts 7 and slide shafts 8 of the two sets of connecting arms 4a and 4b are attached to each of the adjustment blocks 6a and 6b including the slide rails 13 and 14, respectively. The pair of adjustment blocks 6 a and 6 b are assembled into the pair of hinge casings 1 a and 1 b, respectively, and attached to the housing portions 2 a and 3 a provided on the door frame 2 and the door 3.

ここで、蝶番ケーシング１ｂの調整ブロック６ｂはその底部から部分的に突出する構造である。しかしながら、蝶番ケーシング１ａ、１ｂが共用できるように蝶番ケーシング１ａと蝶番ケーシング１ｂはその底部３１が部分的に開放されている同形状の構造体である。このため、外部から収容部２ａ、３ａの内部面が直接見えないように、隠し蝶番１の裏側に構造上発生する隙間等は樹脂等で塞ぐことが好ましい。   Here, the adjustment block 6b of the hinge casing 1b has a structure partially protruding from the bottom. However, the hinge casing 1a and the hinge casing 1b are structures of the same shape in which the bottom 31 is partially opened so that the hinge casings 1a and 1b can be shared. For this reason, it is preferable to block the gap etc. which generate | occur | produces on the back side of the hidden hinge 1 with resin etc. so that the internal surface of accommodating part 2a, 3a cannot be directly seen from the outside.

扉枠２の蝶番ケーシング１ａの垂直方向の下端部に調整ブロック６ａの脱落防止用の板バネからなる爪部９が設けられる。そして、爪部９に対応する扉枠２の調整ブロック６ａの下端部に爪部９と係止する凸状の係止部１０を備える。   A claw portion 9 made of a leaf spring for preventing the adjustment block 6a from falling off is provided at the lower end portion of the hinge casing 1a of the door frame 2 in the vertical direction. And the convex-shaped latching | locking part 10 latched with the nail | claw part 9 is provided in the lower end part of the adjustment block 6a of the door frame 2 corresponding to the nail | claw part 9. FIG.

二組の連結アーム４ａ、４ｂのそれぞれの動作は、図１（ａ）から図２（ａ）、（ｂ）に示すように、扉３が開放された状態から半開きの状態を経て閉じた状態まで動作する間に、垂直回転軸５を中心にして一端Ｓが回転軸７にピン支持されて回転するとともに他端Ｔがスライド軸８でスライドレール１３、１４にスライド支持されて移動する。   As shown in FIGS. 1 (a) to 2 (a) and 2 (b), each of the two sets of connecting arms 4a and 4b is closed from a state where the door 3 is opened to a state where it is half-opened. 1, one end S is supported by the rotation shaft 7 with the vertical rotation shaft 5 as a center and is rotated while the other end T is slidably supported by the slide rails 13 and 14 on the slide shaft 8.

さらに、隠し蝶番１のより詳しい説明を組付け手順に沿って説明する。   Further, a more detailed description of the hidden hinge 1 will be described along the assembly procedure.

図３（ａ）、（ｂ）、図４（ａ）、（ｂ）に示すように、扉枠２用の調整ブロック６ａと扉３用の調整ブロック６ｂにＹ軸方向に貫通する開口部１２ａ、１２ｂが形成され、この開口部１２ａ、１２ｂの上部と下部に調整ブロック６ａ、６ｂとは別体で形成されたスライドレール１３、１４がそれぞれ装着される。
スライドレール１３、１４は直方体形状（幅Ｍ、高さＮ）で調整ブロック６ａ、６ｂに対して垂直でＺ軸方向に取付けられる。スライドレール１３、１４には断面矩形の凹溝レール部１３ａ、１４ａが幅Ｍ４、深さＮ１で形成され、凹溝レール部１３ａ、１４ａはスライドレール１３、１４の一端側にのみ開放されている。この凹溝レール部１３ａ、１４ａは直線状でスライドレール１３、１４のＺ軸に対してＸ軸方向に角度αで互いに対向するように傾斜する。この傾斜により前記扉枠２と扉３の収容部２ａ、３ａの奥行きに制限があっても凹溝レール部１３ａ、１４ａの必要長さを確保することができる。一般扉枠材の枠厚２４ｍｍに対しても対応することができる。 As shown in FIGS. 3 (a), 3 (b), 4 (a), and 4 (b), an opening 12a that penetrates the adjustment block 6a for the door frame 2 and the adjustment block 6b for the door 3 in the Y-axis direction. 12b, and slide rails 13 and 14 formed separately from the adjustment blocks 6a and 6b are mounted on the upper and lower portions of the openings 12a and 12b, respectively.
The slide rails 13 and 14 have a rectangular parallelepiped shape (width M and height N), and are attached to the adjustment blocks 6a and 6b in the Z-axis direction. The slide rails 13 and 14 are formed with concave groove rail portions 13a and 14a having a rectangular cross section with a width M4 and a depth N1, and the concave groove rail portions 13a and 14a are opened only on one end side of the slide rails 13 and 14, respectively. . The concave groove rail portions 13a and 14a are linear and inclined with respect to the Z axis of the slide rails 13 and 14 so as to face each other at an angle α in the X axis direction. Due to this inclination, the required lengths of the recessed groove rail portions 13a and 14a can be secured even if the depths of the accommodating portions 2a and 3a of the door frame 2 and the door 3 are limited. It can respond also to the frame thickness of 24 mm of a general door frame material.

スライドレール１３、１４の両幅端からそれぞれ幅Ｍ１と幅Ｍ３で囲まれた位置に凹溝レール部１３ａ、１４ａが形成される。スライドレール１３、１４が角度αを持っているので、Ｍ２＞Ｍ４の関係に形成される。   Concave groove rail portions 13a and 14a are formed at positions surrounded by widths M1 and M3 from both width ends of the slide rails 13 and 14, respectively. Since the slide rails 13 and 14 have an angle α, a relationship of M2> M4 is formed.

スライドレール１３、１４における凹溝レール部１３ａ、１４ａとは反対側の面１３ｂ、１４ｂに係止部１５が形成される。係止部１５は断面コ字状で面１３ｂ、１４ｂから突出する両側面１５ａ（側面１５ａの長さＴ、高さＳ、両側面間の幅Ｋ）には係止部としての三角柱形状の突起１５ｂが長さＴ１、側面１５ａからの突出幅Ｋ１、側面１５ａにおける取付位置までの高さＳ１で備える。   Locking portions 15 are formed on the surfaces 13b and 14b of the slide rails 13 and 14 opposite to the grooved rail portions 13a and 14a. The locking portion 15 is U-shaped in cross section and has a triangular prism-shaped projection as a locking portion on both side surfaces 15a (length T, height S, width K between both side surfaces 15a) protruding from the surfaces 13b and 14b. 15b includes a length T1, a protruding width K1 from the side surface 15a, and a height S1 up to the mounting position on the side surface 15a.

調整ブロック６ａ、６ｂの上部と下部には矩形状の孔部１６が長さＴ２、幅Ｋ２、孔部１６の厚さＳ１である。ここで、Ｋ＝Ｋ２、Ｔ＝Ｔ２、Ｓ１＝Ｓ２の関係である。   A rectangular hole 16 has a length T2, a width K2, and a thickness S1 of the hole 16 at the upper and lower portions of the adjustment blocks 6a and 6b. Here, the relationship is K = K2, T = T2, and S1 = S2.

このため、突起１５ｂを両側面１５ａの隙間を狭めて孔部１６に挿入したのち、両側面１５ａが弾力で元の位置にもどることにより突起１５ｂが孔部１６の縁部に係止する。これにより、スライドレール１３、１４は調整ブロック６ａ、６ｂに固定される。   For this reason, after the protrusion 15b is inserted into the hole 16 with the gap between the side surfaces 15a being narrowed, the protrusion 15b is locked to the edge of the hole 16 by returning the both side surfaces 15a to the original position. Thereby, the slide rails 13 and 14 are fixed to the adjustment blocks 6a and 6b.

調整ブロック６ａの上下には調整ブロック６ａを蝶番ケーシング１ａへ左右調整可能に取付けるための一対の長孔２０が、調整ブロック６ｂの上下には調整ブロック６ｂを蝶番ケーシング１ｂに対して正面方向に調整可能に取付けるためのネジ孔２１が設けられる。調整ブロック６ａの上下端部に凸状の係止部１０が形成される。   A pair of elongated holes 20 for attaching the adjustment block 6a to the hinge casing 1a so as to be adjustable left and right are provided above and below the adjustment block 6a, and the adjustment block 6b is adjusted in the front direction with respect to the hinge casing 1b above and below the adjustment block 6b. Screw holes 21 are provided for possible attachment. Convex locking portions 10 are formed at the upper and lower ends of the adjustment block 6a.

蝶番ケーシング１ａ、１ｂと調整ブロック６ａ、６ｂと連結アーム４ａ、４ｂはアルミダイカスト材。垂直回転軸５、スライド軸８はステンレス材、スライドレール１３、１４は樹脂成形材である。   The hinge casings 1a and 1b, the adjustment blocks 6a and 6b, and the connecting arms 4a and 4b are made of an aluminum die-cast material. The vertical rotation shaft 5 and the slide shaft 8 are made of stainless steel, and the slide rails 13 and 14 are made of resin molding.

図５に示すように、一組の連結アーム４ａは、一端Ｓに回転軸７を挿入するための軸孔７ａと、他端Ｔにスライド軸８（外径＝Ｍ５）を挿入するための軸孔８ａと、略中央部に垂直回転軸５を挿入するための軸孔５ａを備える。Ｍ４＝Ｍ５に形成される。   As shown in FIG. 5, the set of connecting arms 4a includes a shaft hole 7a for inserting the rotating shaft 7 at one end S and a shaft for inserting the slide shaft 8 (outer diameter = M5) at the other end T. A hole 8a and a shaft hole 5a for inserting the vertical rotation shaft 5 at a substantially central portion are provided. M4 = M5.

そして、連結アーム４ａが調整ブロック６ａに矢印で示すように収納されて、他端Ｔの軸孔８ａにスライド軸８が挿入される。このとき、連結アーム４ａの
アーム補強板１８は一対の孔１８ａを備え、連結アーム４ａの上端には一対の凸部１８ｂ備える。この孔１８ａと凸部１８ｂの係合によってアーム補強板１８は連結アーム４ａとの位置ずれを防止することができる。また、軸孔５ａに垂直回転軸５の固定用の止めネジ１９がネジ込まれる。 Then, the connecting arm 4a is housed in the adjustment block 6a as indicated by an arrow, and the slide shaft 8 is inserted into the shaft hole 8a at the other end T. At this time, the arm reinforcing plate 18 of the connecting arm 4a includes a pair of holes 18a, and the upper end of the connecting arm 4a includes a pair of convex portions 18b. Due to the engagement between the hole 18a and the convex portion 18b, the arm reinforcing plate 18 can be prevented from being displaced from the connecting arm 4a. Further, a set screw 19 for fixing the vertical rotating shaft 5 is screwed into the shaft hole 5a.

アーム補強板１８の目的は、連結アーム４ａがアルミダイカスト材のために脆く、且つ、軸孔５ａ、軸孔７ａ、軸孔８ａの縦方向の長さが長いため、扉の荷重により開閉動作中に各軸との接触による軋み音が発生するとともに、連結アーム４ａが欠けたり最悪折れたりする恐れがある。   The purpose of the arm reinforcing plate 18 is that the connecting arm 4a is brittle because of the aluminum die-cast material, and the longitudinal length of the shaft hole 5a, shaft hole 7a, and shaft hole 8a is long, so that the opening and closing operation is being performed due to the load of the door. In addition, a squeaking noise is generated due to contact with each shaft, and the connecting arm 4a may be chipped or broken.

このため、アーム補強板１８がステンレス材で形成され、アーム補強板１８に形成される各軸孔は軸孔５ａ、軸孔７ａ、軸孔８ａの孔径よりも若干小さくしておくことにより、扉荷重を直接的に受持つことができるので安全性を高めることができる。   For this reason, the arm reinforcing plate 18 is formed of stainless steel, and the shaft holes formed in the arm reinforcing plate 18 are slightly smaller than the diameters of the shaft hole 5a, the shaft hole 7a, and the shaft hole 8a. Safety can be improved because the load can be directly handled.

調整ブロック６ａには調整ブロック６ａを蝶番ケーシング１ａへの取付けるための一対の長孔２０が設けられる。   The adjustment block 6a is provided with a pair of long holes 20 for attaching the adjustment block 6a to the hinge casing 1a.

次に、図６を用いて、他の一組の連結アーム４ｂを調整ブロック６ｂに収納する説明をするが、図５に示す構成と同構成部分については、図面に同符号を付して重複した説明を省略する。なお、連結アーム４ａと連結アーム４ｂは同形状である。   Next, the other set of connecting arms 4b will be described in the adjustment block 6b with reference to FIG. 6, but the same components as those shown in FIG. The description that has been made will be omitted. The connecting arm 4a and the connecting arm 4b have the same shape.

図６に示すように、連結アーム４ｂは連結アーム４ａとは逆に上下反転して調整ブロック６ｂに矢印で示すように収納される。また、連結アーム４ｂの下端にアーム補強板１８が添えられる。調整ブロック６ｂには調整ブロック６ｂを蝶番ケーシング１ｂへの取付けるための一対のネジ孔２１が設けられる。   As shown in FIG. 6, the connecting arm 4b is inverted upside down from the connecting arm 4a and is stored in the adjustment block 6b as indicated by an arrow. In addition, an arm reinforcing plate 18 is attached to the lower end of the connecting arm 4b. The adjustment block 6b is provided with a pair of screw holes 21 for attaching the adjustment block 6b to the hinge casing 1b.

図７に示すように。連結アーム４ａ、４ｂのそれぞれの略中央部の軸孔５ａに垂直回転軸５が挿入され止めネジ１９に固定されてそれぞれの連結アーム４ａ、４ｂが回転自在に連結される。   As shown in FIG. The vertical rotating shaft 5 is inserted into the shaft hole 5a at the substantially central portion of each of the connecting arms 4a and 4b and fixed to the set screw 19 so that the connecting arms 4a and 4b are rotatably connected.

次に、調整ブロック６ｂが扉３側の蝶番ケーシング１ｂ内に固定され、蝶番ケーシング１ｂは孔２６を介してネジ等の固定具３０で扉３の収容部３ａ内に固定される。   Next, the adjustment block 6 b is fixed in the hinge casing 1 b on the door 3 side, and the hinge casing 1 b is fixed in the accommodating portion 3 a of the door 3 with a fixing tool 30 such as a screw through the hole 26.

調整ブロック６ｂの上下のネジ孔２１に左右調整ネジ２５が螺合され、左右調整ネジ２５の先端部は蝶番ケーシング１ｂと図示しないカシメ止めによって回転可能に固定される。このため、上下の左右調整ネジ２５のネジ込代を調整することで扉３の左右方向の位置調整ができる。   The left and right adjustment screws 25 are screwed into the upper and lower screw holes 21 of the adjustment block 6b, and the distal ends of the left and right adjustment screws 25 are rotatably fixed by a hinge casing 1b and a not-shown caulking. For this reason, the position adjustment of the left-right direction of the door 3 can be performed by adjusting the screwing allowance of the upper and lower left-right adjustment screws 25.

次に、図７の状態の隠し蝶番１を扉枠２に近接するが、このとき、図示しない扉枠２側に予め蝶番ケーシング１ａが単独に組付けられている。このため、蝶番ケーシング１ａに調整ブロック６ａが挿入されて爪部９に調整ブロック６ａの係止部１０が係止されて容易に仮固着される。仮付けしたのち、扉枠２の調整ブロック６ａを蝶番ケーシング１ａに本固定される。   Next, the hidden hinge 1 in the state shown in FIG. 7 is brought close to the door frame 2. At this time, the hinge casing 1 a is assembled in advance on the door frame 2 side (not shown). For this reason, the adjustment block 6a is inserted into the hinge casing 1a, and the locking portion 10 of the adjustment block 6a is locked to the claw portion 9 and is easily temporarily fixed. After the temporary attachment, the adjustment block 6a of the door frame 2 is permanently fixed to the hinge casing 1a.

＜隠し蝶番の構造の構成の作用＞
上記、扉枠２用の調整ブロック６ａと扉３用の調整ブロック６ｂはＹ軸方向に貫通する開口部１２ａ、１２ｂが形成され、この開口部１２ａ、１２ｂの上部と下部に調整ブロック６ａ、６ｂとは別体でスライドレール１３、１４がそれぞれ装着される。
このため、スライドレール１３、１４は調整ブロックの露出側表面に対して垂直に取付けることができるので可動型を確実に引抜くことができるのでダイカスト鋳造が容易にできる。また、凹溝レール部１３ａ、１４ａ自体はガイド本体を抉って水平面内で傾きαを持って形成するので、凹溝レール部の必要な長さを容易に確保することができる。 <Operation of the structure of the hidden hinge>
The above-described adjustment block 6a for the door frame 2 and the adjustment block 6b for the door 3 have openings 12a and 12b penetrating in the Y-axis direction, and the adjustment blocks 6a and 6b are formed above and below the openings 12a and 12b. The slide rails 13 and 14 are mounted separately from each other.
For this reason, since the slide rails 13 and 14 can be attached perpendicularly to the exposed side surface of the adjustment block, the movable mold can be reliably pulled out, so that die casting can be easily performed. Further, since the groove groove rail portions 13a and 14a themselves are formed with an inclination α in the horizontal plane across the guide body, the necessary length of the groove groove rail portion can be easily ensured.

突起１５ｂを矩形状の孔部１６に、両側面１５ａの隙間を狭めて孔部１６に挿入したのち、両側面１５ａが弾力で元の形状にもどり突起１５ｂが孔部１６の縁部に係止することで、スライドレール１３、１４は調整ブロック６ａ、６ｂに容易に且つ確実に固定することができる。   After the projection 15b is inserted into the rectangular hole 16 and the gap between the side surfaces 15a is narrowed and inserted into the hole 16, the side surfaces 15a return to their original shape due to elasticity, and the projection 15b is locked to the edge of the hole 16 By doing so, the slide rails 13 and 14 can be easily and reliably fixed to the adjustment blocks 6a and 6b.

以上、本発明の実施形態を図面に基づいて説明したが、上記の実施例はいずれも本発明の一例を示したものであり、本発明はこれらに限定されるべきでないということは言うまでもない。   As mentioned above, although embodiment of this invention was described based on drawing, all said Example shows an example of this invention, and it cannot be overemphasized that this invention should not be limited to these.

例えば、係止部１５を用いないで、スライドレール１３、１４を調整ブロック６ａ、６ｂに接着剤等で直接貼り付けても構わない。この場合は孔部１６は不要である。   For example, the slide rails 13 and 14 may be directly attached to the adjustment blocks 6a and 6b with an adhesive or the like without using the locking portion 15. In this case, the hole 16 is not necessary.
