隠し蝶番は、扉を閉じた状態では間仕切り空間のどちらからも蝶番が見えないので、扉の外観を損なわず、また開閉時の扉と枠体の縦枠との隙間が小さいので、子供等が該隙間で指を詰めるなどの事故を防止できるという利点がある。   Hidden hinges cannot be seen from either partition space when the door is closed, so the appearance of the door is not impaired, and the gap between the door and the vertical frame of the frame when opening and closing is small. There is an advantage that accidents such as clogging fingers in the gap can be prevented.

このような隠し蝶番は、一般に、一端を回動可能に軸支した一対のリンク材が交差配置されて他端が相互に他方のケーシング内へ入り込む基本構成を有している。（特許文献１および非特許文献１）。     Such a hidden hinge generally has a basic configuration in which a pair of link members pivotally supported at one end are arranged so that the other ends enter the other casing. (Patent Document 1 and Non-Patent Document 1).

例えば、非特許文献１に記載された隠し蝶番を図１０に示す。この隠し蝶番を用いた扉の閉状態および１８０°開状態を図１１（a）および(b)にそれぞれ示す。すなわち、扉６０および枠体の縦枠６１の各端面に埋め込み固定されたケーシング６２，６３にそれぞれ略く字形のリンク部材６４，６５が一端を回動可能に軸支されて他端が他方のケーシングへ入り込む交差態様で配設され、交差部分が回動可能に軸支されるとともに、他端に設けたガイドピン６６，６７が他方のケーシングに設けたスライド溝６８，６９にスライド自在に係合した係合した構造を有する   For example, a hidden hinge described in Non-Patent Document 1 is shown in FIG. FIGS. 11A and 11B show the door closed state and 180 ° open state using the hidden hinge, respectively. In other words, substantially rectangular link members 64 and 65 are pivotally supported so that one end can be pivoted in casings 62 and 63 embedded and fixed to the respective end surfaces of the door 60 and the vertical frame 61 of the frame body, and the other end is the other. It is arranged in an intersecting manner so as to enter the casing, and the intersecting portion is pivotally supported so that the guide pins 66 and 67 provided at the other end are slidably engaged with the slide grooves 68 and 69 provided in the other casing. With mated engaged structure

従来の隠し蝶番、特に建物の扉に取付けられる隠し蝶番は、扉の荷重を支持する必要があるため、図１１（a）および(b)に示すように５本のピン６６，６７，７０，７１，７２で扉の荷重を支持するように設計されている。そのため、ケーシングを収容する凹部の間口および奥行が大きくなり、従って扉６０の厚みおよび縦枠６１の厚みも大きくならざるをえなかった。
ところが、近時は、コストダウンの要請から、扉６０や縦枠６１の厚みを薄くすることが要請されている。そのためには、隠し蝶番をコンパクト化することが必要である。 Since the conventional hidden hinge, particularly the hidden hinge attached to the door of the building, needs to support the load of the door, as shown in FIGS. 11 (a) and 11 (b), five pins 66, 67, 70, 71 and 72 are designed to support the load of the door. Therefore, the frontage and depth of the recess for housing the casing are increased, and accordingly, the thickness of the door 60 and the thickness of the vertical frame 61 must be increased.
However, recently, it is required to reduce the thickness of the door 60 and the vertical frame 61 because of a request for cost reduction. To that end, it is necessary to make the hidden hinge compact.

一方、従来の枠体への扉の取付けには、１人の作業員が扉を保持し、他の作業員が扉を枠体に取付けるというように、作業には最低でも作業員が２人必要であった。そのため、作業性、施工性を向上させ、１人の作業員で簡単に扉を取付けることができるようにすることが求められている。   On the other hand, when attaching a door to a conventional frame, one worker holds the door and another worker attaches the door to the frame so that at least two workers are required for the work. It was necessary. Therefore, it is required to improve workability and workability so that a single worker can easily attach the door.

本発明の主たる課題は、コンパクト化が可能な隠し蝶番を提供することである。本発明の他の課題は、扉の取付けに際しての作業性、施工性が向上した隠し蝶番を提供することである。   The main subject of this invention is providing the hidden hinge which can be reduced in size.

A wood screw or the like is inserted to be fixed to the vertical frame 2 and the door 1 respectively. In the following description, “up and down” refers to the up and down direction in a use state incorporated in a door and a vertical frame.

図２に示すように、扉１側のケーシング3は、主としてケーシング本体３aと、位置調節部材３bとから構成される。ケーシング本体３aは金属板材を断面ハット形に形成し、かつ片側に板材を折り曲げて側壁３ｃが形成されている。ケーシング本体３aの底面には、位置調節用の複数の孔６，７，８が穿設されている。また、位置調節部材３ｂも、同様に金属板材を折り曲げて片側に側壁３ｄを形成すると共に、該側壁３ｄの先端中央部には、板金加工にて金属板材の一部を筒状に曲げてピン挿通孔９が形成されている。位置調節部材３ｂの底面には、位置調節用の複数の孔１０，１１，１２が穿設されている。さらに、位置調節部材３ｂの下部には、スライド溝１３が形成されたガイド部３eが板材を水平に折り曲げて形成されている。なお、３ｆはケーシング本体３aの側面部に嵌め付ける側壁である。   As shown in FIG. 2, the casing 3 on the door 1 side is mainly composed of a casing body 3a and a position adjusting member 3b. The casing body 3a is formed of a metal plate with a cross-sectional hat shape, and a side wall 3c is formed by bending the plate on one side. A plurality of holes 6, 7 and 8 for position adjustment are formed in the bottom surface of the casing body 3a. Similarly, the position adjusting member 3b also bends the metal plate material to form a side wall 3d on one side, and at the center of the tip of the side wall 3d, a part of the metal plate material is bent into a cylindrical shape by sheet metal processing. An insertion hole 9 is formed. A plurality of holes 10, 11, and 12 for position adjustment are formed in the bottom surface of the position adjustment member 3b. Further, a guide portion 3e in which a slide groove 13 is formed is formed at the lower portion of the position adjusting member 3b by bending a plate material horizontally. In addition, 3f is a side wall fitted in the side part of the casing main body 3a.

一方、縦枠２側のケーシング４は、扉１側のケーシング3と同様に、主としてケーシング本体４aと、位置調節部材４ｂとから構成される。ケーシング本体４aは、前面が開口した箱形で構成され、その上下に取付孔5を形成した鍔部１４が形成されている。ケーシング本体４aの底面には２つのねじ孔１５が穿設されている。また、位置調節部材４ｂは、金属板材を折り曲げて片側に側壁４ｄを形成すると共に、該側壁４ｄの先端両側部に、板金加工にて金属板材の一部を筒状に曲げてピン挿通孔１６，１６が形成されている。位置調節部材４ｂの底面には、水平方向に長い位置調節用の長孔１７が穿設されている（図１を参照）。さらに、位置調節部材４ｂの上部には、スライド溝１８が形成されたガイド部４eが水平に折り曲げ形成されている。   On the other hand, the casing 4 on the vertical frame 2 side is mainly composed of a casing body 4a and a position adjusting member 4b, similarly to the casing 3 on the door 1 side. The casing body 4a is formed in a box shape having an open front surface, and has a flange portion 14 formed with attachment holes 5 on the upper and lower sides thereof. Two screw holes 15 are formed in the bottom surface of the casing body 4a.

さらに、縦枠側ピン２７（軸棒）を下側ガイドアーム３１のピン挿通孔３５、縦枠２側の位置調節部材４ｂの下部ピン挿通孔１６、第２リンク材２０のピン挿通孔２４、縦枠２側の位置調節部材４ｂの上部ピン挿通孔１６の順に挿通させて、第２リンク材２０と縦枠２側の位置調節部材４ｂとを回動可能に連結する。挿通後、上部ピン挿通孔１６を外周面からプレスして縦枠側ピン２７に圧着させるのがよい。   Further, the vertical frame side pin 27 (shaft bar) is connected to the pin insertion hole 35 of the lower guide arm 31, the lower pin insertion hole 16 of the position adjustment member 4b on the vertical frame 2 side, the pin insertion hole 24 of the second link member 20, The second link member 20 and the position adjusting member 4b on the vertical frame 2 side are rotatably connected by being inserted in the order of the upper pin insertion holes 16 of the position adjusting member 4b on the vertical frame 2 side. After the insertion, the upper pin insertion hole 16 may be pressed from the outer peripheral surface and crimped to the vertical frame side pin 27.

以上の組立て課程において、上側ガイドアーム３０のガイドピン３６は、縦枠２側の位置調節部材４ｅの上部ガイド部４ｃに設けたスライド溝に上方から係合させる。一方、下側ガイドアーム３１のガイドピン３7は、扉１側の位置調節部材３ｂの下部ガイド部３ｅに設けたスライド溝に下方から係合させる。   In the above assembly process, the guide pin 36 of the upper guide arm 30 is engaged from above with a slide groove provided in the upper guide portion 4c of the position adjusting member 4e on the vertical frame 2 side. On the other hand, the guide pin 37 of the lower guide arm 31 is engaged with the slide groove provided in the lower guide portion 3e of the position adjusting member 3b on the door 1 side from below.

次に、扉１側の位置調節部材３ｂをケーシング本体３ａに取付ける。取付けは、後述する固定ねじ３８，３８および上下方向調節ねじ３９によって行われる。図４は位置調節部材３ｂをケーシング本体３ａに取付けた状態を示す断面図である。すなわち、図２および図４に示すように、固定ねじ３８，３８は位置調節部材３ｂに設けた長穴１０を挿通してケーシング本体３ａのねじ穴に螺合する。上下方向調節ねじ３９は、ワッシャ４０、偏心カム４１、ワッシャ４０を介して位置調節部材３ｂのねじ挿通孔１２およびケーシング本体３ａのねじ挿通孔８を挿通させ、ケーシング本体３ａの裏面側に配置された袋ナット４２に螺合する。このようにしてケーシング本体３ａに取付けた後、ケーシング本体３ａを扉１の端面に設けた凹部１００内に嵌めこみ、取付け孔５を挿通した取付けねじ（図示せず）で扉１に固定する。   Next, the position adjusting member 3b on the door 1 side is attached to the casing body 3a. The attachment is performed by fixing screws 38 and 38 and a vertical adjustment screw 39 which will be described later. FIG. 4 is a cross-sectional view showing a state in which the position adjusting member 3b is attached to the casing body 3a. That is, as shown in FIGS. 2 and 4, the fixing screws 38, 38 are inserted through the long holes 10 provided in the position adjusting member 3b and screwed into the screw holes of the casing body 3a. The vertical adjustment screw 39 is disposed through the washer 40, the eccentric cam 41, and the washer 40 through the screw insertion hole 12 of the position adjustment member 3b and the screw insertion hole 8 of the casing body 3a, and is disposed on the back side of the casing body 3a. Screw into the cap nut 42. After being attached to the casing body 3 a in this way, the casing body 3 a is fitted into a recess 100 provided on the end face of the door 1 and fixed to the door 1 with an attachment screw (not shown) inserted through the attachment hole 5.

一方、縦枠２の端面に設けた凹部１０１内には、あらかじめケーシング本体４ａがその取付け孔５を挿通した取付けねじ（図５に下部の取付けねじ４６を示す）によって固定されている。このとき、ケーシング本体４ａの内部下端面には、係合突起部４３が設けられている（図２参照）。また、ケーシング本体４ａの内部下端面と対向するように、位置調節部材４ｂの下端部には水平方向に折り曲げた折曲片４４が設けられており、この折曲片４４に長穴状の孔部４５が穿設されている(図３参照）。
孔部４５を長穴状にしているのは、本実施形態では、後述するように位置調節部材４ｂがケーシング本体４ａに対して前後位置調節機能を有しているので、当該前後位置調節に際して係合突起部４３が障害とならないようにするためである。 On the other hand, in the recess 101 provided on the end face of the vertical frame 2, the casing body 4 a is fixed in advance by a mounting screw (a lower mounting screw 46 is shown in FIG. 5) inserted through the mounting hole 5. At this time, an engaging projection 43 is provided on the inner bottom surface of the casing body 4a (see FIG. 2). In addition, a bent piece 44 bent in the horizontal direction is provided at the lower end portion of the position adjusting member 4b so as to face the inner lower end surface of the casing body 4a, and an elongated hole-like hole is formed in the bent piece 44. A portion 45 is drilled (see FIG. 3).
In the present embodiment, the hole 45 is formed in the shape of a long hole, as will be described later, since the position adjusting member 4b has a function of adjusting the front / rear position with respect to the casing body 4a. This is so that the joint protrusion 43 does not become an obstacle.

扉１を縦枠２の端面に取付けるには、図５および図６に示すように、扉１を持って縦枠側位置調節部材４ｂの下端部の端をケーシング本体４ａの下端面上に載置し、そのまま縦枠２の奥に押し込むと、折曲片４４の孔部４５に係合突起部４３が係合して、扉１を仮止めすることができる。これによって、従来、扉を持つ作業者と、扉を縦枠に固定する作業者とを必要としたのに対して、一人の作業者が扉を持ちながら、上記のように簡単に扉１を仮止めすることができるので、扉１を縦枠２の端面に取付ける作業性、施工性が大幅に向上する。
仮止め後、前後方向位置調節ねじ４６を長穴１７より挿通させ、ケーシング本体４ａの底面に設けたねじ孔１５に螺合させて扉１を縦枠２へ取付ける。
なお、前記係合突起部４３は、ケーシング本体４ａの上下端の内面に設けておくのが好ましい。これにより、ケーシング本体４ａを枠体２内に固定する際に、ケーシング本体４ａの上下を考慮することなく作業できるので、作業性、施工性が向上する。 To attach the door 1 to the end face of the vertical frame 2, as shown in FIGS. 5 and 6, hold the door 1 and place the end of the lower end of the vertical frame side position adjusting member 4b on the lower end face of the casing body 4a. If it is placed and pushed into the depth of the vertical frame 2 as it is, the engagement protrusion 43 is engaged with the hole 45 of the bent piece 44 and the door 1 can be temporarily fixed. As a result, a worker who has a door and a worker who fixes the door to the vertical frame are conventionally required, but a single worker can easily hold the door 1 as described above while holding the door. Since it can be temporarily fixed, the workability and workability of attaching the door 1 to the end face of the vertical frame 2 are greatly improved.
After the temporary fixing, the front / rear direction position adjusting screw 46 is inserted through the elongated hole 17 and screwed into the screw hole 15 provided in the bottom surface of the casing body 4a to attach the door 1 to the vertical frame 2.
The engaging protrusions 43 are preferably provided on the inner surfaces of the upper and lower ends of the casing body 4a. Thereby, when fixing the casing main body 4a in the frame 2, since work can be performed without considering the upper and lower sides of the casing main body 4a, workability and workability are improved.

扉１の取付け後、扉１の取付け位置を調節する。すなわち、縦枠２に対して扉１を上下方向、左右方向および前後方向に位置調節する。本実施形態では、扉１側の位置調節部材３ｂの底面に上下方向および左右方向の位置調節手段が設けられ、縦枠２側の位置調節部材４ｂの底面に前後方向の位置調節手段が設けられている。   After the door 1 is attached, the attachment position of the door 1 is adjusted. That is, the position of the door 1 is adjusted in the vertical direction, the horizontal direction, and the front-rear direction with respect to the vertical frame 2. In this embodiment, vertical and horizontal position adjusting means are provided on the bottom surface of the position adjusting member 3b on the door 1 side, and front and rear position adjusting means are provided on the bottom surface of the position adjusting member 4b on the vertical frame 2 side. ing.

以下、扉１の取付け位置調節手段および方法を説明する。
＜左右方向の位置調節＞
図４に示すように、扉１側のケーシング本体３ａの底面に設けた孔７の裏面側にはナット部材４７が固着されており、このナット部材４７に皿ねじ４８（左右方向調節ねじ）を螺合させる。ついで、前記したように位置調節部材３ｂをケーシング本体３ａ内に収容する。このとき、皿ねじ４８の上部に長穴１１が位置するように構成される。この長穴１１は皿ねじ４８に対してドライバー(図示せず)を挿入して操作でき、且つ皿ねじ４８が抜け出さない間隙を有する。従って、図７(a)、(b)に示すように、図示しないドライバーで皿ねじ４８を回してケーシング本体３ａの底面から皿ねじ４８を上げていくと、この皿ねじ４８に押されて位置調節部材３ｂが上がり、逆方向に回すと位置調節部材３ｂが下がる。これによって扉１を縦枠２に対して左右方向（矢印Ａで示す）に位置調節することができる。 Hereinafter, the attachment position adjusting means and method of the door 1 will be described.
<Left and right position adjustment>
As shown in FIG. 4, a nut member 47 is fixed to the back surface side of the hole 7 provided in the bottom surface of the casing body 3 a on the door 1 side, and a countersunk screw 48 (lateral adjustment screw) is attached to the nut member 47. Screw together. Next, as described above, the position adjusting member 3b is accommodated in the casing body 3a. At this time, the elongated hole 11 is configured to be positioned above the countersunk screw 48. The elongated hole 11 can be operated by inserting a screwdriver (not shown) into the countersunk screw 48, and has a gap in which the countersunk screw 48 does not come out. Therefore, as shown in FIGS. 7A and 7B, when the flat head screw 48 is turned by a screwdriver (not shown) and the flat head screw 48 is lifted from the bottom surface of the casing body 3a, the flat head screw 48 is pushed to the position. When the adjustment member 3b is raised and turned in the opposite direction, the position adjustment member 3b is lowered. Thereby, the position of the door 1 can be adjusted with respect to the vertical frame 2 in the left-right direction (indicated by the arrow A).

このとき、所望の位置で確実に位置調節部材３ｂをケーシング本体３ａに固定（ロック）する必要がある。そのための手段として、固定ねじ３８が皿ねじ４８の近くに設けられる。この固定ねじ３８は、位置調節部材３ｂの長穴１０を挿通して、ケーシング本体３ａに設けたねじ孔６に螺合している。そのため、左右方向の位置調節時には、あらかじめ固定ねじ３８をゆるめて、位置調節部材３ｂを固定しないフリーな状態にし、この状態で前記皿ねじ４８を回して左右方向の位置調節を行い、位置調節後、固定ねじ３８を締め付ける。これにより、位置調節部材３ｂは皿ねじ４８の頭部に当接して止まるので、所望の位置で確実に固定することができる。
長穴１０、１１を上下方向に長く形成しているのは、後述する上下位置調節に障害とならないようにするためである。 At this time, it is necessary to securely fix (lock) the position adjusting member 3b to the casing body 3a at a desired position. As a means for that, a fixing screw 38 is provided near the countersunk screw 48. The fixing screw 38 is inserted into the elongated hole 10 of the position adjusting member 3b and screwed into the screw hole 6 provided in the casing body 3a. Therefore, when adjusting the position in the left-right direction, the fixing screw 38 is loosened in advance so that the position adjusting member 3b is not fixed, and in this state, the countersunk screw 48 is rotated to adjust the position in the left-right direction. Then, the fixing screw 38 is tightened. Thereby, the position adjusting member 3b comes into contact with the head of the countersunk screw 48 and stops, so that it can be reliably fixed at a desired position.
The reason why the long holes 10 and 11 are long in the vertical direction is to prevent the vertical position adjustment described later from becoming an obstacle.

＜前後方向の位置調節＞
図１に示すように、位置調節部材４ｂの底面には、水平方向に長い長孔１７が穿設されており、この長穴１７を挿通した前後方向位置調節ねじ４６を、ケーシング本体４ａの底面に設けたねじ孔１５に螺合させている。そのため、調節ねじ４６をゆるめ、位置調節部材４ｂを水平方向に長孔１７に沿って所望の位置までスライドさせ、再び調節ねじ４６を締め付ければよい。このようにして、扉１の位置を図７に矢印Ｂで示す前後方向に調節することができる。 <Position adjustment in the front-rear direction>
As shown in FIG. 1, a long hole 17 that is long in the horizontal direction is formed in the bottom surface of the position adjusting member 4b, and a longitudinal position adjusting screw 46 inserted through the long hole 17 is connected to the bottom surface of the casing body 4a. Are screwed into the screw holes 15 provided in. Therefore, the adjustment screw 46 is loosened, the position adjustment member 4b is slid in the horizontal direction along the long hole 17 to a desired position, and the adjustment screw 46 is tightened again. In this way, the position of the door 1 can be adjusted in the front-rear direction indicated by the arrow B in FIG.

＜上下方向の位置調節＞
扉1の上下方向の位置調節手段は、図２および図４に示すように、上下方向調節ねじ３９、ワッシャ４０、偏心カム４１、ワッシャ４０、およびケーシング本体３ａの裏面側に配置された袋ナット４２から構成される。偏心カム４１には上記調節ねじ３９と螺合するねじ孔３９ａが形成されている。この偏心カム４１を位置調節部材３ｂのねじ挿通孔１２に挿入し、両側にワッシャ４０、４０を配置した状態で、調節ねじ３９をワッシャ４０、４０のねじ挿通孔に挿通させ、偏心カム４１のねじ孔３９ａに螺合させた後、さらにケーシング本体３ａのねじ挿通孔８に挿通させて、袋ナット４２と螺合させ、ワッシャ４０、偏心カム４１およびワッシャ４０を一体に圧着する。 <Position adjustment in the vertical direction>
As shown in FIGS. 2 and 4, the vertical position adjusting means for the door 1 includes a vertical adjustment screw 39, a washer 40, an eccentric cam 41, a washer 40, and a cap nut disposed on the back side of the casing body 3a. 42. The eccentric cam 41 is formed with a screw hole 39a to be screwed with the adjusting screw 39. The eccentric cam 41 is inserted into the screw insertion hole 12 of the position adjusting member 3b, and the adjusting screw 39 is inserted into the screw insertion holes of the washers 40, 40 in a state where the washers 40, 40 are arranged on both sides. After screwing into the screw hole 39a, it is further inserted into the screw insertion hole 8 of the casing body 3a and screwed into the cap nut 42, and the washer 40, the eccentric cam 41, and the washer 40 are crimped together.

位置調節部材３ｂのねじ挿通孔１２は、偏心カム４１の回動に従動して位置調節部材３ｂを上下動させる形状を有する。位置調節部材３ｂの上下方向の位置調節を行うには、調節ねじ３９を左右いずれかの方向に回動させると、これに伴って図８に示すように、偏心カム４１が回動し、図８(a)に示す低位置から、同図（ｂ）に示す中間位置を経て、図８(ｃ)に示す高位置までの任意の上下位置に位置調節部材３ｂを調節することができ、これによって立て枠2に対する扉１の位調節置を簡単に行うことができる。   The screw insertion hole 12 of the position adjusting member 3b has a shape that moves the position adjusting member 3b up and down following the rotation of the eccentric cam 41. To adjust the position of the position adjusting member 3b in the vertical direction, when the adjusting screw 39 is rotated in either the left or right direction, the eccentric cam 41 is rotated as shown in FIG. The position adjusting member 3b can be adjusted to any vertical position from the low position shown in FIG. 8 (a) to the high position shown in FIG. 8 (c) through the intermediate position shown in FIG. 8 (b). Thus, the position adjustment of the door 1 with respect to the standing frame 2 can be easily performed.

次に、本実施形態に係る隠し蝶番を用いた扉の開閉動作を図９(a)〜（e）に基づいて説明する。図９(a)は扉１を縦枠２に対して１８０°開いた状態を示している。この状態では、各ガイドアーム３０，３１の中央部のピン挿通孔３２，３３を挿通した中央ピン２５は扉１および縦枠２よりも外側に位置している。この状態から扉１を閉方向に回動させると、各ガイドアーム３０，３１のガイドピン３６，３７がそれぞれ係合するスライド溝１３，１８に沿ってスライドする。すなわち、扉1を開いた図９(a)の状態から同図の（ｂ）、（ｃ）、（ｄ）を経て、扉1を閉じた図９（e）の状態になる。図９（e）に示す閉じた状態では、図９(a)のときと違い、ガイドピン３６，３７はスライド溝１３，１８の反対側に位置している。   Next, the opening / closing operation | movement of the door using the hidden hinge which concerns on this embodiment is demonstrated based on Fig.9 (a)-(e). FIG. 9A shows a state in which the door 1 is opened 180 degrees with respect to the vertical frame 2. In this state, the center pin 25 inserted through the pin insertion holes 32 and 33 at the center of the guide arms 30 and 31 is positioned outside the door 1 and the vertical frame 2. When the door 1 is rotated in the closing direction from this state, the guide pins 36 and 37 of the guide arms 30 and 31 slide along the slide grooves 13 and 18 respectively engaged. That is, the state shown in FIG. 9A with the door 1 opened is changed to the state shown in FIG. 9E with the door 1 closed through (b), (c) and (d) in FIG. In the closed state shown in FIG. 9 (e), the guide pins 36 and 37 are located on the opposite side of the slide grooves 13 and 18, unlike the case of FIG. 9 (a).

図９(a)〜（e）に示すように、本発明では、扉１と縦枠２との隙間Ｃは、殆ど変化がなく、本実施形態では約５ｍｍ以下と小さく設定されているので、幼児等が誤って扉１と縦枠２との隙間Ｃに指を挟む危険性をなくすことができ、安全性が高まる。   As shown in FIGS. 9 (a) to 9 (e), in the present invention, the gap C between the door 1 and the vertical frame 2 is almost unchanged, and is set to be as small as about 5 mm or less in this embodiment. The risk of an infant or the like accidentally pinching a finger in the gap C between the door 1 and the vertical frame 2 can be eliminated, and safety is improved.

以上のように、本発明に係る隠し蝶番は、扉の外観を損なわず、また指を詰めるなどの事故を防止でき安全性が高いという利点を有すると共に、回動自在に連結されたケーシング３，4の上下にガイドアーム３０，３１を配設した、いわゆる３層構造とすることにより、コンパクト化が可能となり、そのため扉や縦枠の薄型化に対応することができるようになる。
また、上記のように３層構造とすることにより、扉１を任意な開き角度（例えば９０°、１８０°等）で開いた状態で、ケーシング３，4内にドライバーを差し込んで３方向の位置調節ができるようにしたので、隠し蝶番のコンパクト化により大きく寄与することができる。
さらに、ケーシング本体４ａの内部下端面に係合突起部４３を設け、ケーシング本体４ａへの位置調節部材４ｂの取付け時に、該係合突起部４３を位置調節部材４ｂの孔部４５に係合させて仮止めすることができるので、扉１の取付け作業が簡単に成り、扉の取付けに際しての作業性、施工性が向上する。 As described above, the concealed hinge according to the present invention has the advantage that it does not impair the appearance of the door, prevents accidents such as clogging fingers, and is highly safe, and has a casing 3 that is rotatably connected. By adopting a so-called three-layer structure in which guide arms 30 and 31 are arranged above and below 4, compactness can be achieved, so that it is possible to cope with thinning of doors and vertical frames.
Further, by adopting a three-layer structure as described above, a screwdriver is inserted into the casings 3 and 4 in a state where the door 1 is opened at an arbitrary opening angle (for example, 90 °, 180 °, etc.). Since it can be adjusted, it can greatly contribute to the compactness of the hidden hinge.
Furthermore, an engagement protrusion 43 is provided on the inner bottom surface of the casing body 4a, and when the position adjustment member 4b is attached to the casing body 4a, the engagement protrusion 43 is engaged with the hole 45 of the position adjustment member 4b. Therefore, the door 1 can be easily attached and the workability and workability of the door can be improved.

なお、本発明は上記の実施形態に限定されるものではなく、特許請求の範囲の記載の範囲内において種々の改良や変更が可能であることはいうまでもない。   In addition, this invention is not limited to said embodiment, It cannot be overemphasized that various improvement and a change are possible within the range of description of a claim.
