Description

本発明は、建物の開口部に障子がピポットヒンジ装置で回動自在に支持された建具に関する。   The present invention relates to a joinery in which a shoji is rotatably supported by a pivot hinge device at an opening of a building.

建具であるドアの扉を枠体に開閉自在に取り付ける構造として、扉の吊元側となる上下の隅部にピポットヒンジ機構を配置したものが知られている(例えば、特許文献1参照)。
特許文献1において、扉の下部に設けられるピポットヒンジ機構は、下枠の上面に固定される板状のベース部に、ピポット軸部を上方に向けて突設している。また、扉の下面には、円筒状の軸挿入部を設けている。
そして、扉を傾けた状態で、ピポット軸部に対する軸挿入部の位置合わせを行い、ピポット軸部を軸挿入部に挿入してピポットヒンジ機構を構成している。
As a structure for attaching a door of a door, which is a joiner, to a frame body so as to be freely opened and closed, a structure in which a pivot hinge mechanism is arranged at the upper and lower corners on the door suspension side is known (for example, see Patent Document 1).
In Patent Document 1, a pivot hinge mechanism provided at a lower portion of a door is provided with a pivot base portion protruding upward on a plate-like base portion fixed to the upper surface of a lower frame. A cylindrical shaft insertion portion is provided on the lower surface of the door.
Then, with the door tilted, the shaft insertion portion is aligned with the pivot shaft portion, and the pivot shaft mechanism is configured by inserting the pivot shaft portion into the shaft insertion portion.

特開2009−180052号公報JP 2009-180052 A

しかしながら、前記特許文献1に記載された従来のピポットヒンジ機構では、ピポット軸部と軸挿入部の位置合わせを行う際は扉を傾けることができても、軸挿入部が円筒状なので、軸挿入部にピポット軸部を挿入する際には扉を傾けることができない。このため、扉を吊り込む際の作業に制約が多く、施工性が低下するという不都合がある。このことは、ドアに限らず、障子を建物の開口部にピポットヒンジ装置で回動自在に支持する各種建具においても同様である。   However, in the conventional pivot pivot mechanism described in Patent Document 1, the shaft insertion portion is cylindrical even when the door can be tilted when positioning the pivot shaft portion and the shaft insertion portion. The door cannot be tilted when the pivot shaft part is inserted into the part. For this reason, there are many restrictions in the operation | work at the time of hanging a door, and there exists a problem that workability falls. This is the same not only for doors but also for various fittings that support a shoji in the opening of the building with a pivot hinge device.

本発明の目的は、障子の吊り込み作業時の施工性を高めることができる建具を提供することにある。   The objective of this invention is providing the fitting which can improve the workability at the time of the suspension work of a shoji.

本発明の建具は、開口部内に配置される障子と、前記障子を回動自在に支持するピポットヒンジ装置とを備えた建具であって、前記ピポットヒンジ装置は、前記障子の上面およびこの障子の上面に対向する開口部の上面間に配置される上部ヒンジ装置と、前記障子の下面およびこの障子の下面に対向する開口部の下面間に配置される下部ヒンジ装置とを備え、前記下部ヒンジ装置は、鉛直軸を有し、前記開口部の下面または障子の下面の一方に取り付けられた下部ベース部材と、前記鉛直軸が配置される軸孔を有し、前記開口部の下面または障子の下面の他方に取り付けられた下部受け部材とを備え、前記軸孔は、軸方向に沿って直径が変化するテーパー状の孔部を備え、前記下部受け部材の前記下部ベース部材に対向する対向面における前記軸孔の周囲には、上下方向において前記下部ベース部材に対向する面で当該下部ベース部材に接触する突起部が形成され、前記対向面は、前記下部ベース部材に対して離間して位置することを特徴とする。 The joinery of the present invention is a joinery including a shoji disposed in an opening and a pivot hinge device that rotatably supports the shoji, and the pivot hinge device includes an upper surface of the shoji and the shoji of the shoji. An upper hinge device disposed between upper surfaces of openings facing the upper surface; and a lower hinge device disposed between a lower surface of the shoji and a lower surface of the opening facing the lower surface of the shoji. Has a vertical axis and has a lower base member attached to one of the lower surface of the opening or the lower surface of the shoji, and a shaft hole in which the vertical shaft is disposed, and the lower surface of the opening or the lower surface of the shoji A lower receiving member attached to the other end of the lower receiving member, and the shaft hole includes a tapered hole portion whose diameter changes along the axial direction, and the lower receiving member has a surface facing the lower base member. Previous Around the shaft hole, the protrusion in contact with the lower base member is formed in a surface facing the lower base member in the vertical direction, the facing surface may be spaced apart with respect to said lower base member It is characterized by.

ここで、本発明の建具は、玄関ドア、勝手口ドア、浴室ドア、室内ドアなどの各種のドアや、鉛直軸を回転軸として開閉するスイング系の窓、折れ戸、折りたたみ窓などに適用できる。また、開口部は、壁に形成された開口に枠体を配置して構成してもよいし、壁の開口および床で直接構成してもよい。
また、前記軸孔は、下部ベース部材の鉛直軸が配置されるため、前記テーパー状(すり鉢状)の孔部の直径の最小値は、当然ながら前記鉛直軸の直径よりも大きくされている。また、テーパー状の孔部の傾斜面の角度(軸孔の軸方向に対する角度)は、障子の吊り込み時の障子の傾斜角度に応じて設定されている。
さらに、軸孔は、軸孔全体がテーパー状に形成されていてもよいし、軸孔の一部がテーパー状に形成されていてもよい。たとえば、軸孔としては、テーパー状の孔部と、この孔部に連続する円筒状のフラットな(軸孔の軸方向の平行な)孔部が形成されたものでもよい。
Here, the joinery of the present invention can be applied to various doors such as an entrance door, a doorway door, a bathroom door, and an indoor door, a swing-type window that opens and closes around a vertical axis, a folding door, and a folding window. . In addition, the opening may be configured by arranging a frame in an opening formed in the wall, or may be configured directly by the opening of the wall and the floor.
Further, since the shaft hole is arranged with the vertical axis of the lower base member, the minimum diameter of the tapered (mortar-shaped) hole is naturally larger than the diameter of the vertical shaft. Further, the angle of the inclined surface of the tapered hole (the angle with respect to the axial direction of the shaft hole) is set according to the inclination angle of the shoji when the shoji is suspended.
Furthermore, the shaft hole may be formed in a tapered shape as a whole, or a part of the shaft hole may be formed in a tapered shape. For example, as the shaft hole, a tapered hole portion and a cylindrical flat hole portion (parallel to the axial direction of the shaft hole) continuous to the hole portion may be formed.

以上の本発明によれば、障子の下部ヒンジ装置において、下部受け部材の軸孔に、テーパー状の孔部を設けたので、下部ベース部材の鉛直軸が前記孔部のテーパー面(傾斜面)に沿う角度まで障子を傾斜させることができる。このため、障子を傾けたままで、軸孔に鉛直軸を挿通できるので、障子を開口部に吊り込む作業の施工性を向上できる。   According to the present invention described above, in the lower hinge device for a shoji, since the tapered hole is provided in the shaft hole of the lower receiving member, the vertical axis of the lower base member is the tapered surface (inclined surface) of the hole. The shoji can be tilted to an angle along. For this reason, since the vertical shaft can be inserted into the shaft hole while the shoji is tilted, the workability of the operation of hanging the shoji into the opening can be improved.

また、本発明の建具における突起部としては、軸孔の開口外周に沿ってリング状に形成されたものでもよいし、複数の円弧部に分かれて形成されたものでもよい。
このような本発明によれば、下部ベース部材に対向する下部受け部材の面(対向面)において、軸孔の周囲に突起部が形成されているので、障子の吊り込み時に、この突起部を支点に障子を傾けることができ、障子を容易に傾けることができる。
さらに、障子を吊り込んだ後、下部受け部材と下部ベース部材との接触部分、つまりは障子と開口部下面の接触部分を前記突起部のみにできる。このため、障子と開口部下面の接触面積を小さくでき、障子を回動させる場合の摺動抵抗を小さくできる。このため、障子をスムーズに開閉することができる。
Moreover , as a projection part in the fitting of this invention, the thing formed in the ring shape along the opening outer periphery of a shaft hole may be sufficient, and it may be divided and formed in the some circular arc part.
According to the present invention , since the protrusion is formed around the shaft hole on the surface (opposing surface) of the lower receiving member facing the lower base member, this protrusion is The shoji can be tilted to the fulcrum, and the shoji can be easily tilted.
Furthermore, after the shoji is suspended, the contact portion between the lower receiving member and the lower base member, that is, the contact portion between the shoji and the lower surface of the opening can be formed only by the protrusion. For this reason, the contact area between the shoji and the lower surface of the opening can be reduced, and the sliding resistance when the shoji is rotated can be reduced. For this reason, the shoji can be opened and closed smoothly.

また、本発明の建具では、前記上部ヒンジ装置は、鉛直軸を有し、前記障子の上面またはこの障子の上面に対向する開口部の上面の一方に取り付けられた上部ベース部材と、前記鉛直軸が配置される軸孔を有し、前記障子の上面またはこの障子の上面に対向する開口部の上面の他方に取り付けられた上部受け部材とを備え、前記上部受け部材には、当該上部受け部材の側面から前記軸孔まで連続し、前記鉛直軸の直径よりも大きな幅寸法の軸案内溝が形成されていることが好ましい。
このような構成によれば、上部ヒンジ装置を、上部ベース部材と、上部受け部材とで構成している。ここで、上部ベース部材は、下部ベース部材と同様に、鉛直軸を有して開口部や障子に取り付けられる。従って、上部ベース部材と下部ベース部材とは、部品を兼用して利用することもでき、部品コストを低減できる。
また、上部受け部材は、その側面から軸孔まで連続する軸案内溝が形成されているので、前記上部ベース部材の鉛直軸を、上部受け部材の側面から軸孔まで移動させることができる。このため、障子の吊り込み時に、上部ベース部材および上部受け部材を、高さ方向にずらして吊り込む必要が無い。従って、障子を傾けて、下部受け部材の軸孔に、下部ベース部材の鉛直軸を挿入し、その後、障子を水平に戻しながら、前記上部受け部材の軸案内溝から軸孔まで、上部ベース部材の鉛直軸を移動することで、障子を枠体内に吊り込むことができる。従って、施工作業性を向上できる。
In the joinery of the present invention, the upper hinge device has a vertical axis, and is attached to one of the upper surface of the shoji or the upper surface of the opening facing the upper surface of the shoji, and the vertical shaft There has shaft holes are arranged, and a top or upper receiving member attached to the other of the upper surface of the opening facing the upper surface of the sliding door of the shoji, the upper receiving member, the upper receiving member It is preferable that a shaft guide groove that is continuous from the side surface to the shaft hole and has a width that is larger than the diameter of the vertical shaft is formed.
According to such a configuration, the upper hinge device includes the upper base member and the upper receiving member. Here, similarly to the lower base member, the upper base member has a vertical axis and is attached to the opening or the shoji. Therefore, the upper base member and the lower base member can also be used as parts, and the part cost can be reduced.
Further, since the upper receiving member is formed with a shaft guide groove continuous from the side surface to the shaft hole, the vertical axis of the upper base member can be moved from the side surface of the upper receiving member to the shaft hole. For this reason, when the shoji is suspended, it is not necessary to suspend the upper base member and the upper receiving member by shifting in the height direction. Accordingly, the shoji is tilted, the vertical shaft of the lower base member is inserted into the shaft hole of the lower receiving member, and then the upper base member is moved from the shaft guide groove to the shaft hole of the upper receiving member while returning the shoji to horizontal. The shoji can be hung in the frame by moving the vertical axis. Therefore, construction workability can be improved.

さらに、本発明の建具では、前記軸案内溝の前記軸孔側の端部の内面には、突起が形成されていることが好ましい。
このような構成によれば、軸案内溝の端部、つまり軸孔との接続部分に突起が形成されているので、軸孔に移動した鉛直軸が軸案内溝に戻ってしまうことを規制できる。このため、障子を吊り込む際に、下部ヒンジ装置の軸孔に鉛直軸を配置し、上部ヒンジ装置の鉛直軸を軸案内溝から前記突起を超えて軸孔に移動すれば、作業者が障子を常時保持する必要がなくなる。このため、固定具を用いて上部ヒンジ装置の鉛直軸を固定する際に、他の作業者が障子を保持している必要がないため、一人の作業者で障子の吊り込み作業を行うことができ、作業性を向上できる。
Furthermore, in the joinery of the present invention, it is preferable that a protrusion is formed on the inner surface of the end portion on the shaft hole side of the shaft guide groove.
According to such a configuration, since the protrusion is formed at the end of the shaft guide groove, that is, the connection portion with the shaft hole, it is possible to restrict the vertical shaft that has moved to the shaft hole from returning to the shaft guide groove. . For this reason, when the shoji is suspended, if the vertical shaft is arranged in the shaft hole of the lower hinge device and the vertical shaft of the upper hinge device is moved from the shaft guide groove to the shaft hole beyond the projection, the operator can Need not be held all the time. For this reason, when fixing the vertical axis of the upper hinge device using a fixing tool, it is not necessary for another worker to hold the shoji, so it is possible for one worker to hang the shoji. And workability can be improved.

また、本発明の建具では、前記軸案内溝は、前記上部受け部材の障子見付面に開口され、この開口から障子見込み方向に延長され、さらに前記障子の吊元側に折曲されて前記軸孔に連続していることが好ましい。
このような構成によれば、軸案内溝は、上部受け部材の障子見付面から障子見込み方向に延長された後、吊元側に折曲され、その先に配置された軸孔に連続している。そして、開口部に吊り込まれた障子は、自重によって開口部に対して戸先側に移動する方向の力が加わる。このため、軸孔に配置された鉛直軸は吊元側に向かう方向に力が加わる。このため、軸孔に配置された鉛直軸が、軸孔の戸先側に連続する軸案内溝側に移動することを防止できる。従って、固定具を用いて上部ヒンジ装置の鉛直軸を固定する際に、他の作業者が障子を保持している必要がないため、一人の作業者で障子の吊り込み作業を行うことができ、作業性を向上できる。
Further, in the fittings of the present invention, the shaft guide groove, said opened in the shoji find surface of the upper receiving member, extending from the opening in the sliding door prospective direction, is further bent Tsumoto side of the shoji the It is preferable that it is continuous with the shaft hole.
According to such a configuration, the shaft guide groove is extended from the shoji finding surface of the upper receiving member in the direction in which the shoji is expected, and then bent to the suspending side and continues to the shaft hole arranged at the tip. ing. And the force of the direction which moves to the door-end side with respect to an opening part is added to the shoji suspended in the opening part with dead weight. For this reason, a force is applied to the vertical shaft arranged in the shaft hole in a direction toward the suspension base side. For this reason, it can prevent that the vertical axis | shaft arrange | positioned at a shaft hole moves to the shaft guide groove side continuous to the door-end side of a shaft hole. Therefore, when fixing the vertical shaft of the upper hinge device using a fixture, it is not necessary for another operator to hold the shoji, so one operator can hang the shoji. , Workability can be improved.

また、本発明の建具では、前記軸案内溝は、前記上部受け部材の吊元側の障子見込面に開口され、この開口から障子の戸先側に延長され、さらに前記障子の見込み方向または前記障子の吊元側に折曲されて前記軸孔に連続していることが好ましい。
このような構成によれば、軸案内溝は、上部受け部材の吊元側の障子見込面から障子戸先側に延長される。さらに、障子の見込み方向に折曲されて軸孔に連続する平面略L字状の軸案内溝とされたり、障子の吊元側に折曲されて軸孔に連続する平面略J字状の軸案内溝とされる。そして、開口部に吊り込まれた障子は、自重によって開口部に対して戸先側に移動する方向の力が加わる。このため、軸孔に配置された鉛直軸は吊元側に向かう方向に力が加わる。よって、軸孔に配置された鉛直軸が、軸孔の見付面側や戸先側に連続する軸案内溝側に移動することを防止できる。従って、固定具を用いて上部ヒンジ装置の鉛直軸を固定する際に、他の作業者が障子を保持している必要がないため、一人の作業者で障子の吊り込み作業を行うことができ、作業性を向上できる。
Further, in the fittings of the present invention, the shaft guide groove, the upper receiving opened in the shoji expected surface of Tsumoto side member, extending from the opening on the door tip side of the sash, further prospective direction or the of the shoji It is preferable that it bends to the suspension side of the shoji and continues to the shaft hole.
According to such a configuration, the shaft guide groove is extended from the expected shoji surface on the suspension base side of the upper receiving member to the shoji door end side. Furthermore, it is made into a plane substantially L-shaped shaft guide groove that is bent in the expected direction of the shoji and continues to the shaft hole, or is substantially J-shaped in a plane that is bent to the suspension side of the shoji and continues to the shaft hole. It is a shaft guide groove. And the force of the direction which moves to the door-end side with respect to an opening part is added to the shoji suspended in the opening part with dead weight. For this reason, a force is applied to the vertical shaft arranged in the shaft hole in a direction toward the suspension base side. Therefore, it is possible to prevent the vertical shaft disposed in the shaft hole from moving to the shaft guide groove side that is continuous with the surface of the shaft hole and the door end side. Therefore, when fixing the vertical shaft of the upper hinge device using a fixture, it is not necessary for another operator to hold the shoji, so one operator can hang the shoji. , Workability can be improved.

孔部261の下端には、円筒状、つまり直径が一定のフラット部262が連続して形成されている。従って、孔部261の最も小さい直径と、フラット部262の直径とは同一径とされている。軸孔26は鉛直軸23が挿通されるため、前記フラット部262の直径は、当然ながら鉛直軸23の直径よりも大きい。
フラット部262の下端には、下部受け部材25の下面開口に向かって径が大きくなるテーパー状の第2孔部263が形成されている。
従って、軸孔26は、上面側から下面側に向かって連続する孔部261、フラット部262、第2孔部263によって構成されている。
The lower receiving member 25 is made of a resin plate-like member. As shown in FIG. 2 and FIG. 3 when the lower receiving member 25 is viewed from the lower surface side, a shaft hole 26 through which the vertical shaft 23 is inserted, and a screw hole 27. And are formed.
The shaft hole 26 is formed through the lower receiving member 25 vertically. As shown in FIG. 4, the shaft hole 26 includes a tapered (mortar-shaped) hole portion 261 whose diameter increases upward. The upper end of the hole portion 261 is opened on the upper surface of the lower receiving member 25, and the upper end of the hole portion 261 is the portion with the largest diameter.
A cylindrical portion, that is, a flat portion 262 having a constant diameter is continuously formed at the lower end of the hole portion 261. Therefore, the smallest diameter of the hole portion 261 and the diameter of the flat portion 262 are the same. Since the shaft hole 26 is inserted through the vertical shaft 23, the diameter of the flat portion 262 is naturally larger than the diameter of the vertical shaft 23.
At the lower end of the flat portion 262, a tapered second hole portion 263 whose diameter increases toward the lower surface opening of the lower receiving member 25 is formed.
Accordingly, the shaft hole 26 includes a hole portion 261, a flat portion 262, and a second hole portion 263 that are continuous from the upper surface side toward the lower surface side.

下部受け部材25の下面、つまり下部ベース部材21に対向する対向面251には、図3に示すように、突起部28が形成されている。突起部28は、軸孔26の下面開口(第2孔部263)の周囲にリング状に形成されている。
突起部28の下面281はフラットな平面とされ、突起部28の側面282はR形状に湾曲されている。また、突起部28の前記対向面251からの突出寸法Lは、図4(B)に示すように、突起部28の下面281が、下部ベース部材21の上面に接触している際に、対向面251が下部ベース部材21に接触しない状態に設定できればよい。このため、この突出寸法Lは、たとえば1.5mm程度に設定される。
前記孔部261のテーパー面の傾斜角度Aは、図4(A)に示すように、扉3を角度Bまで傾けることができるように設定すればよい。すなわち、扉3をドア枠2に吊り込む際に必要な傾斜角度Bに基づいて、前記傾斜角度Aを設定すればよい。
なお、本実施形態では、第2孔部263の軸方向の長さは、突起部28の突出寸法Lとほぼ同じである。従って、フラット部262も軸孔26において比較的下端に近い位置に形成されている。そして、下部受け部材25を下部ベース部材21に対して回動した際には、前記フラット部262が鉛直軸23にガイドされる。
As shown in FIG. 3, a protrusion 28 is formed on the lower surface of the lower receiving member 25, that is, the facing surface 251 facing the lower base member 21. The protrusion 28 is formed in a ring shape around the lower surface opening (second hole 263) of the shaft hole 26.
The lower surface 281 of the protrusion 28 is a flat plane, and the side surface 282 of the protrusion 28 is curved in an R shape. The protrusion dimension L of the protrusion 28 from the facing surface 251 is opposite when the lower surface 281 of the protrusion 28 is in contact with the upper surface of the lower base member 21 as shown in FIG. It suffices if the surface 251 can be set so as not to contact the lower base member 21. For this reason, this protrusion dimension L is set to about 1.5 mm, for example.
The inclination angle A of the tapered surface of the hole 261 may be set so that the door 3 can be inclined to the angle B as shown in FIG. That is, the inclination angle A may be set based on the inclination angle B required when the door 3 is suspended from the door frame 2.
In the present embodiment, the axial length of the second hole 263 is substantially the same as the protruding dimension L of the protrusion 28. Accordingly, the flat portion 262 is also formed at a position relatively close to the lower end in the shaft hole 26. When the lower receiving member 25 is rotated with respect to the lower base member 21, the flat portion 262 is guided by the vertical shaft 23.

[上部ヒンジ装置]
上部ヒンジ装置30は、図5に示すように、上枠4の下面に取り付けられた上部ベース部材31と、扉3の上面に取り付けられた上部受け部材35と、固定具39を備える。上枠4の下面は、障子である扉3の上面に対向する面であり、本発明の開口部の上面である。
上部ベース部材31は、金属板製のプレート32と、プレート32に固定された金属製の鉛直軸33で構成されている。プレート32には、ネジ孔34が形成されている。そして、上部ベース部材31は、図示しない皿ネジをネジ孔34から上枠4にねじ込むことで、上枠4に固定されている。
この上部ベース部材31は、下部ベース部材21と同一構成であり、下部ベース部材21、上部ベース部材31は同じ部品を兼用して利用できる。
[Upper hinge device]
As shown in FIG. 5, the upper hinge device 30 includes an upper base member 31 attached to the lower surface of the upper frame 4, an upper receiving member 35 attached to the upper surface of the door 3, and a fixture 39. The lower surface of the upper frame 4 is a surface facing the upper surface of the door 3 that is a shoji, and is the upper surface of the opening of the present invention.
The upper base member 31 includes a metal plate 32 and a metal vertical shaft 33 fixed to the plate 32. A screw hole 34 is formed in the plate 32. The upper base member 31 is fixed to the upper frame 4 by screwing a countersunk screw (not shown) into the upper frame 4 from the screw hole 34.
The upper base member 31 has the same configuration as that of the lower base member 21, and the lower base member 21 and the upper base member 31 can be used by sharing the same components.

上部受け部材35は、樹脂製の板状部材からなり、図5に示すように、鉛直軸33が挿通される軸孔36と、ネジ穴37と、軸案内溝38とが形成されている。この上部受け部材35は、扉3の上面の吊元側に形成された段部3Aに、図示しない皿ネジをネジ穴37から扉3にねじ込むことで扉3に固定されている。また、段部3Aには、前記軸孔36および軸案内溝38に連続する溝3Bが形成されている。   The upper receiving member 35 is made of a resin plate-like member, and as shown in FIG. 5, a shaft hole 36 through which the vertical shaft 33 is inserted, a screw hole 37, and a shaft guide groove 38 are formed. The upper receiving member 35 is fixed to the door 3 by screwing a countersunk screw (not shown) into the door 3 through a screw hole 37 into a step portion 3A formed on the hanging base side of the upper surface of the door 3. In addition, a groove 3B that is continuous with the shaft hole 36 and the shaft guide groove 38 is formed in the step portion 3A.

軸孔36および軸案内溝38は、図6にも示すように、連続して形成されている。すなわち、軸案内溝38は、上部受け部材35の扉3の屋内側の側面(扉見付面)351に開口され、この開口から扉見込み方向に延長され、さらに扉3の吊元側に折曲されている。そして、軸案内溝38は、前記軸孔36の戸先側に接続されている。
軸案内溝38の軸孔36側の端部、つまり軸案内溝38と軸孔36との接続部分の両内面には、突起381が形成されている。この対向配置された2つの突起381間の寸法は、鉛直軸33の直径よりも僅かに小さく設定されている。そして、鉛直軸33が、軸案内溝38から軸孔36に移動するように扉3を移動すると、扉3の自重により上部受け部材35が戸先側に移動しようとする。このため、鉛直軸33が突起381に大きな力で当接し、樹脂製である上部受け部材35のばね性によって突起381間の寸法が広がり、鉛直軸33を軸案内溝38から軸孔36に移動できるように設計されている。なお、鉛直軸33の先端(下端)は上部受け部材35の下面よりも突出し、前記溝3B内を案内される。
また、鉛直軸33が軸孔36に配置された後は、扉3の自重によって、鉛直軸33が軸孔36の吊元側に当接する方向に力が加わるため、通常は、鉛直軸33が軸案内溝38側に戻ることはない。また、扉3の自重が加わる方向と逆方向に力が加わった場合でも、前記突起381で鉛直軸33が係止されるため、鉛直軸33が軸孔36から軸案内溝38に移動することを防止できる。従って、この状態でも扉3は容易には脱落しない。
The shaft hole 36 and the shaft guide groove 38 are continuously formed as shown in FIG. That is, the shaft guide groove 38 is opened in the indoor side surface (door finding surface) 351 of the door 3 of the upper receiving member 35, extends from this opening in the door expected direction, and is further folded on the hanging side of the door 3. It is tuned. The shaft guide groove 38 is connected to the door end side of the shaft hole 36.
Projections 381 are formed on the end of the shaft guide groove 38 on the shaft hole 36 side, that is, on both inner surfaces of the connecting portion between the shaft guide groove 38 and the shaft hole 36. The dimension between the two protrusions 381 arranged to face each other is set to be slightly smaller than the diameter of the vertical shaft 33. When the door 3 is moved so that the vertical shaft 33 moves from the shaft guide groove 38 to the shaft hole 36, the upper receiving member 35 tends to move to the door end side due to its own weight. Therefore, the vertical shaft 33 comes into contact with the protrusion 381 with a large force, and the dimension between the protrusions 381 is widened by the spring property of the upper receiving member 35 made of resin, and the vertical shaft 33 is moved from the shaft guide groove 38 to the shaft hole 36. Designed to be able to. The tip (lower end) of the vertical shaft 33 protrudes from the lower surface of the upper receiving member 35 and is guided in the groove 3B.
In addition, after the vertical shaft 33 is disposed in the shaft hole 36, a force is applied in a direction in which the vertical shaft 33 abuts on the suspending side of the shaft hole 36 due to the weight of the door 3. There is no return to the shaft guide groove 38 side. Even when a force is applied in the direction opposite to the direction in which the weight of the door 3 is applied, the vertical shaft 33 is locked by the protrusion 381, and thus the vertical shaft 33 moves from the shaft hole 36 to the shaft guide groove 38. Can be prevented. Accordingly, even in this state, the door 3 does not easily fall off.

固定具39は、金属板材を折曲して形成されたものであり、上面に溝391が形成され、側面にネジ穴392が形成されている。そして、図7に示すように、ネジ393をネジ穴392から扉3にねじ込むことで、固定具39は扉3に固定される。この際、固定具39の上面は、上部受け部材35の上面に沿って配置され、溝391は軸孔36に配置された鉛直軸33を吊元側および戸先側から挟み込むように保持する。このため、鉛直軸33は、固定具39によって保持されて軸孔36から軸案内溝38に移動することがない。   The fixture 39 is formed by bending a metal plate material. A groove 391 is formed on the upper surface, and a screw hole 392 is formed on the side surface. Then, as shown in FIG. 7, the fixing tool 39 is fixed to the door 3 by screwing the screw 393 into the door 3 through the screw hole 392. At this time, the upper surface of the fixture 39 is disposed along the upper surface of the upper receiving member 35, and the groove 391 holds the vertical shaft 33 disposed in the shaft hole 36 so as to be sandwiched from the suspension base side and the door end side. For this reason, the vertical shaft 33 is held by the fixture 39 and does not move from the shaft hole 36 to the shaft guide groove 38.

ここで、扉3の段部3Aは、扉3の上面より上部受け部材35および固定具39の厚さ寸法分低く形成されているため、固定具39の上面と扉3の上面とがほぼ同じ高さレベルとなる。   Here, since the step 3A of the door 3 is formed lower than the upper surface of the door 3 by the thickness dimension of the upper receiving member 35 and the fixture 39, the upper surface of the fixture 39 and the upper surface of the door 3 are substantially the same. Become a height level.

[ドアの施工手順]
以上の本発明では、ドア枠2に対して、扉3を吊り込む場合、図8に示すように、作業者は、ドア枠2の室外側で扉3を斜めに傾けて吊り上げ、扉3下部の吊元側をドア枠2内に移動し、下部ベース部材21の鉛直軸23に、下部受け部材25の軸孔26を合わせる。そして、扉3を傾けたまま下方に移動して、鉛直軸23に軸孔26を挿入する。
次に、扉3を水平に起こしつつ、上部ベース部材31の鉛直軸33に、軸案内溝38の側面開口を合わせ、扉3の上部をドア枠2内に押し込む。すると、鉛直軸33は軸案内溝38から、突起381を超えて軸孔36に移動する。ここで、鉛直軸23、33は、同軸上に配置されているので、軸孔26、36も同軸上に配置され、扉3の上下両面は水平に配置される。
次に、作業者は、扉3を室外側に開いて、室内に移動する。扉3を開いた場合、扉3の自重によって上部受け部材35は戸先側に傾く方向に力が加わり、軸孔36内に配置された鉛直軸33は吊元側に移動する方向に力が加わる。この扉3の自重および突起381により、鉛直軸33が軸案内溝38側に戻ることがないため、仮に作業者が扉3を保持していない場合でも、扉3がドア枠2から外れることがない。扉3の室内側に移動した作業者は、扉3の室内側から固定具39を取り付ける。これにより、扉3は、下部ヒンジ装置20、上部ヒンジ装置30からなるピポットヒンジ装置によって、ドア枠2に対して回動自在(外開き自在)に取り付けられる。
[Door installation procedure]
In the present invention described above, when the door 3 is suspended from the door frame 2, as shown in FIG. 8, the operator lifts the door 3 by tilting the door 3 obliquely outside the door frame 2. Is moved into the door frame 2, and the shaft hole 26 of the lower receiving member 25 is aligned with the vertical shaft 23 of the lower base member 21. Then, the door 3 is moved downward while being tilted, and the shaft hole 26 is inserted into the vertical shaft 23.
Next, while raising the door 3 horizontally, the side opening of the shaft guide groove 38 is aligned with the vertical shaft 33 of the upper base member 31, and the upper portion of the door 3 is pushed into the door frame 2. Then, the vertical shaft 33 moves from the shaft guide groove 38 to the shaft hole 36 over the projection 381. Here, since the vertical shafts 23 and 33 are disposed coaxially, the shaft holes 26 and 36 are also disposed coaxially, and the upper and lower surfaces of the door 3 are disposed horizontally.
Next, the operator opens the door 3 to the outdoor side and moves into the room. When the door 3 is opened, a force is applied to the upper receiving member 35 in a direction in which the upper receiving member 35 is inclined toward the door tip side due to the weight of the door 3, and a force is applied to the vertical shaft 33 disposed in the shaft hole 36 in a direction to move toward the suspension base side. Join. Due to the weight of the door 3 and the protrusion 381, the vertical shaft 33 does not return to the shaft guide groove 38 side. Therefore, even when the operator does not hold the door 3, the door 3 may come off the door frame 2. Absent. The worker who has moved to the indoor side of the door 3 attaches the fixture 39 from the indoor side of the door 3. Thereby, the door 3 is attached to the door frame 2 so as to be rotatable (openable) by the pivot hinge device including the lower hinge device 20 and the upper hinge device 30.

[第1実施形態の効果]
以上のような本実施形態によれば、下部ヒンジ装置20において、下部ベース部材21の鉛直軸23が配置される下部受け部材25の軸孔26に、テーパー状の孔部261を設けたので、鉛直軸23を軸孔26に挿入した状態で、扉3を容易にかつ比較的大きな角度で傾けることができる。このため、扉3をドア枠2に吊り込む作業の施工性を向上できる。
さらに、本実施形態では、上部ヒンジ装置30において、軸孔36の戸先側に軸案内溝38を連続させ、かつ、突起381を形成して、鉛直軸33を係止できるようにしたので、扉3の吊り込み作業から固定具39の固定作業まで、一人の作業者で施工できる。
[Effect of the first embodiment]
According to the present embodiment as described above, in the lower hinge device 20, the tapered hole portion 261 is provided in the shaft hole 26 of the lower receiving member 25 in which the vertical shaft 23 of the lower base member 21 is disposed. With the vertical shaft 23 inserted into the shaft hole 26, the door 3 can be easily tilted at a relatively large angle. For this reason, the workability of the operation | work which hangs the door 3 in the door frame 2 can be improved.
Furthermore, in the present embodiment, in the upper hinge device 30, the shaft guide groove 38 is continued on the door end side of the shaft hole 36, and the projection 381 is formed so that the vertical shaft 33 can be locked. From the hanging work of the door 3 to the fixing work of the fixture 39, it can be constructed by one worker.

また、下部ヒンジ装置20は、下部ベース部材21および下部受け部材25の2つの部品で構成され、下部ベース部材21、下部受け部材25自体もシンプルな構造である。同様に、上部ヒンジ装置30も、上部ベース部材31、上部受け部材35、固定具39の3つの部品で構成され、各部品もシンプルな構造である。このように、下部ヒンジ装置20、上部ヒンジ装置30は、シンプルな構造なので、容易に製造、組立でき、コストも低減できる。その上、下部ベース部材21、上部ベース部材31は、同一部品で兼用できるため、コストもより低減できる。その上、構造がシンプルであるため、下部ヒンジ装置20、上部ヒンジ装置30部分のデザインもすっきりしたものにでき、意匠性も向上できる。   The lower hinge device 20 includes two parts, a lower base member 21 and a lower receiving member 25, and the lower base member 21 and the lower receiving member 25 themselves have a simple structure. Similarly, the upper hinge device 30 is also composed of three parts, an upper base member 31, an upper receiving member 35, and a fixture 39, and each part has a simple structure. Thus, since the lower hinge device 20 and the upper hinge device 30 have a simple structure, they can be easily manufactured and assembled, and the cost can be reduced. In addition, since the lower base member 21 and the upper base member 31 can be shared by the same component, the cost can be further reduced. In addition, since the structure is simple, the design of the lower hinge device 20 and the upper hinge device 30 can be made clean and the design can be improved.

さらに、下部ベース部材21、上部ベース部材31の鉛直軸23、33を受ける軸孔26、36を下部受け部材25、上部受け部材35に形成しているので、特許文献1のように、枠に軸が挿入される切欠を加工する必要がない。すなわち、下部ベース部材21、上部ベース部材31や下部受け部材25、上部受け部材35は、取付ネジでドア枠2や扉3に取り付けることができ、切欠加工などの必要がない。このため、切欠加工によるドア枠2や扉3の水密性低下や漏水などを防止できる。
さらに、固定具39は、扉3の室内面に取り付けられているので、扉3を閉めている場合に、屋外側から取り外されることがなく、防犯性も向上できる。
Further, shaft holes 26 and 36 for receiving the vertical shafts 23 and 33 of the lower base member 21 and the upper base member 31 are formed in the lower receiving member 25 and the upper receiving member 35. There is no need to machine the notch into which the shaft is inserted. That is, the lower base member 21, the upper base member 31, the lower receiving member 25, and the upper receiving member 35 can be attached to the door frame 2 or the door 3 with mounting screws, and there is no need for notching or the like. For this reason, the watertightness fall of the door frame 2 and the door 3 by a notch process, a water leak, etc. can be prevented.
Furthermore, since the fixture 39 is attached to the indoor surface of the door 3, when the door 3 is closed, it is not removed from the outdoor side, and crime prevention can be improved.

下部受け部材25の対向面(下面)251に突起部28を形成したので、扉3側の下部受け部材25と、ドア枠2側の下部ベース部材21との接触面積を、前記突起部28の下面281の面積のみに小さくできる。このため、扉3を回動させる場合の摺動抵抗を小さくでき、扉3をスムーズに開閉することができる。さらに、扉3の吊り込み時に、突起部28を支点に扉3を容易に傾けることができ、この点でも施工性を向上できる。   Since the protruding portion 28 is formed on the opposing surface (lower surface) 251 of the lower receiving member 25, the contact area between the lower receiving member 25 on the door 3 side and the lower base member 21 on the door frame 2 side is set to be equal to that of the protruding portion 28. Only the area of the lower surface 281 can be reduced. For this reason, the sliding resistance in the case of rotating the door 3 can be made small, and the door 3 can be opened and closed smoothly. Furthermore, when the door 3 is suspended, the door 3 can be easily tilted with the protrusion 28 as a fulcrum, and the workability can also be improved in this respect.

軸孔26は、孔部261、フラット部262、第2孔部263の順で形成し、孔部261の軸方向の長さ寸法(孔の深さ寸法)が最も大きく、フラット部262、第2孔部263の軸方向の長さは孔部261に比べて小さくされている。このため、扉3を回動した際に鉛直軸23にガイドされるフラット部262は、鉛直軸23の根元に近い位置に設けられ、扉3の回動に伴い鉛直軸23に力が加わっても、根元に近い部分に力が加わるため、その力を確実に支持できる。   The shaft hole 26 is formed in the order of the hole portion 261, the flat portion 262, and the second hole portion 263, and the axial length dimension (hole depth dimension) of the hole portion 261 is the largest. The length of the two holes 263 in the axial direction is smaller than that of the holes 261. Therefore, the flat portion 262 that is guided by the vertical shaft 23 when the door 3 is rotated is provided at a position near the base of the vertical shaft 23, and a force is applied to the vertical shaft 23 as the door 3 rotates. However, since a force is applied to the portion close to the root, the force can be reliably supported.

[第2実施形態]
次に、本発明の第2実施形態について説明する。
第2実施形態は、図9,10に示すように、上部ヒンジ装置30Aの構成、特に軸案内溝38Aの開口が吊元側に形成されている点が相違する。
すなわち、第2実施形態の上部ヒンジ装置30Aは、上部ベース部材31Aと、上部受け部材35Aと、固定具39Aとを備える。
上部受け部材35Aは、軸孔36Aと、軸案内溝38Aと、ネジ穴37とを備える。
軸案内溝38Aは、上部受け部材35Aの吊元側の端面に開口し、戸先側に向かって延長され、扉3の見込み方向に折曲され、さらに、吊元側に折曲されている。すなわち、軸案内溝38Aは、平面形状が略J字状に形成されている。このため、軸案内溝38Aは、軸孔36Aの戸先側に連続している。
また、扉3の段部3Aには、軸孔36A、軸案内溝38Aに合わせて、溝3Cが形成されている。
[Second Embodiment]
Next, a second embodiment of the present invention will be described.
As shown in FIGS. 9 and 10, the second embodiment is different from the configuration of the upper hinge device 30 </ b> A, particularly in that the opening of the shaft guide groove 38 </ b> A is formed on the hanging base side.
That is, the upper hinge device 30A of the second embodiment includes an upper base member 31A, an upper receiving member 35A, and a fixture 39A.
The upper receiving member 35A includes a shaft hole 36A, a shaft guide groove 38A, and a screw hole 37.
The shaft guide groove 38A opens on the end surface on the suspension base side of the upper receiving member 35A, extends toward the door end side, is bent in the prospective direction of the door 3, and is further bent on the suspension base side. . That is, the shaft guide groove 38A is formed in a substantially J shape in plan view. For this reason, the shaft guide groove 38A is continuous with the door end side of the shaft hole 36A.
Further, a groove 3C is formed in the step 3A of the door 3 so as to match the shaft hole 36A and the shaft guide groove 38A.

前記軸案内溝38Aの開口は、上部受け部材35Aの吊元側の端面の幅方向中央部に形成されている。このため、軸孔36Aは、上部受け部材35Aの見込み方向の中央よりもずれた位置に形成されている。
この軸案内溝38Aの軸孔36Aに連続する端部には、前記第1実施形態と同様に、鉛直軸33を係止する突起381が形成されている。なお、一方の突起381は、軸案内溝38Aの折曲部分で囲まれた薄板部352に形成されている。
The opening of the shaft guide groove 38A is formed at the center in the width direction of the end surface of the upper receiving member 35A on the suspension base side. For this reason, the shaft hole 36A is formed at a position shifted from the center in the prospective direction of the upper receiving member 35A.
A projection 381 for locking the vertical shaft 33 is formed at the end of the shaft guide groove 38A that is continuous with the shaft hole 36A, as in the first embodiment. One projection 381 is formed on a thin plate portion 352 surrounded by a bent portion of the shaft guide groove 38A.

上部ベース部材31Aは、第1実施形態の上部ベース部材31に対し、鉛直軸33の位置が軸孔36Aに合わせてずれている点以外は、同じ構成である。
固定具39Aは、固定具39と同様に、上面に溝391Aが形成されている。この固定具39Aは、図9に示すように、扉3の吊元側の端面(見込み面)に図示しないネジで固定される。そして、固定具39Aは、その溝391A内に、鉛直軸33を配置することで、鉛直軸33が軸案内溝38Aに戻らないように保持している。
The upper base member 31A has the same configuration with respect to the upper base member 31 of the first embodiment except that the position of the vertical shaft 33 is shifted in accordance with the shaft hole 36A.
Similarly to the fixture 39, the fixture 39A has a groove 391A formed on the upper surface. As shown in FIG. 9, the fixing tool 39 </ b> A is fixed to an end surface (expected surface) on the hanging side of the door 3 with a screw (not shown). The fixture 39A holds the vertical shaft 33 so as not to return to the shaft guide groove 38A by disposing the vertical shaft 33 in the groove 391A.

第2実施形態の下部ヒンジ装置は、図示を略すが、上部ヒンジ装置30Aの鉛直軸33および軸孔36Aに同軸となる位置に、鉛直軸23および軸孔26が形成されている以外は、第1実施形態と同じ構成である。   Although the illustration of the lower hinge device of the second embodiment is omitted, the second hinge device is the same as that of the upper hinge device 30A except that the vertical shaft 23 and the shaft hole 26 are formed at positions coaxial with the vertical shaft 33 and the shaft hole 36A. It is the same structure as 1 embodiment.

[ドアの施工手順]
第2実施形態でもドアの施工手順は第1実施形態とほぼ同一である。ただし、軸案内溝38Aが扉3の吊元側の面に開口しているため、軸案内溝38A内に鉛直軸33を移動する際に、扉3をドア枠2に対してほぼ直交する向きに配置する必要がある。
[Door installation procedure]
Also in the second embodiment, the door construction procedure is substantially the same as in the first embodiment. However, since the shaft guide groove 38A is opened on the surface of the door 3 on the hanging base side, when the vertical shaft 33 is moved into the shaft guide groove 38A, the door 3 is oriented substantially perpendicular to the door frame 2. Need to be placed in.

[第2実施形態の効果]
以上の第2実施形態によれば、第1実施形態と同様の効果を奏することができる。
また、軸案内溝38Aの開口や固定具39Aが扉3の吊元側の見込み面に形成、固定されているので、扉3を閉めた際に、固定具39Aが屋外や室内に露出しない。このため、固定具39Aが外部から取り外されることがないため、防犯性を向上でき、かつ、ドア1の意匠性も向上できる。
[Effects of Second Embodiment]
According to the second embodiment described above, the same effects as those of the first embodiment can be obtained.
Further, since the opening of the shaft guide groove 38A and the fixture 39A are formed and fixed on the prospective surface on the hanging side of the door 3, the fixture 39A is not exposed outdoors or indoors when the door 3 is closed. For this reason, since fixing tool 39A is not removed from the exterior, crime prevention can be improved and the designability of door 1 can also be improved.

さらに、軸案内溝38Aが平面略J字状に形成されているので、軸孔36Aに配置された鉛直軸33が軸案内溝38Aに戻り、さらに軸案内溝38Aの開口から外れる可能性が低く、固定具39Aで固定する前でも、扉3を確実に保持できる。
また、一方の突起381が薄板部352に形成されているので、鉛直軸33を軸案内溝38Aから軸孔36Aに押し込む際に、薄板部352が弾性変形し、そのばね性によって突起381間を広げたり、元に戻したりできる。このため、鉛直軸33を軸案内溝38Aから軸孔36Aにスムーズに移動できる。
Further, since the shaft guide groove 38A is formed in a substantially plane J shape, it is unlikely that the vertical shaft 33 disposed in the shaft hole 36A returns to the shaft guide groove 38A and further disengages from the opening of the shaft guide groove 38A. Even before fixing with the fixing tool 39A, the door 3 can be securely held.
Also, since one projection 381 is formed on the thin plate portion 352, when the vertical shaft 33 is pushed from the shaft guide groove 38A into the shaft hole 36A, the thin plate portion 352 is elastically deformed, and the spring property causes the gap between the projections 381. Can be expanded or restored. For this reason, the vertical shaft 33 can be smoothly moved from the shaft guide groove 38A to the shaft hole 36A.

[変形例]
なお、本発明は、前記実施形態に限定されるものではなく、本発明の目的が達成できる他の構成等を含み、以下に示すような変形等も本発明に含まれる。
たとえば、前記第2実施形態の軸案内溝38Aは、平面略J字状に形成していたが、図11に示すように、平面略L字状に形成してもよい。すなわち、図11に示す上部受け部材35Bの軸案内溝38Bは、上部受け部材35Bの吊元側の端面に開口し、戸先側に向かって延長され、扉3の見込み方向に折曲され、軸孔36Bの見付け面側に連続している。
[Modification]
In addition, this invention is not limited to the said embodiment, Including other structures etc. which can achieve the objective of this invention, the deformation | transformation etc. which are shown below are also contained in this invention.
For example, the shaft guide groove 38A of the second embodiment is formed in a substantially plane J shape, but may be formed in a substantially plane L shape as shown in FIG. That is, the shaft guide groove 38B of the upper receiving member 35B shown in FIG. 11 opens in the end surface on the hanging base side of the upper receiving member 35B, extends toward the door end side, and is bent in the prospective direction of the door 3. The shaft hole 36B is continuous with the finding surface side.

また、図11に示すように、軸案内溝38Bに沿ってスリット355を形成して、一方の突起381が形成される薄板部353を構成してもよい。この薄板部353のばね性により、鉛直軸33は、突起381を容易に超えて軸孔36Bに移動できる。このスリット355によるばねは、第1実施形態の上部受け部材35でも利用できる。   In addition, as shown in FIG. 11, a thin plate portion 353 on which one projection 381 is formed may be formed by forming a slit 355 along the shaft guide groove 38B. Due to the spring property of the thin plate portion 353, the vertical shaft 33 can easily move beyond the protrusion 381 to the shaft hole 36B. The spring by the slit 355 can also be used in the upper receiving member 35 of the first embodiment.

さらに、上部ヒンジ装置30の固定具は、扉3にネジで固定されるものに限らない。図12に示す固定具40のように、上部受け部材35に形成された溝41に挿入片42を挿入し、ネジを用いずに上部受け部材35に固定してもよい。
要するに、固定具は、上部受け部材の軸孔に配置された上部ベース部材の軸が、軸案内溝側に移動することを規制できるものであればよい。
Furthermore, the fixture of the upper hinge device 30 is not limited to that fixed to the door 3 with screws. Like the fixture 40 shown in FIG. 12, the insertion piece 42 may be inserted into the groove 41 formed in the upper receiving member 35 and fixed to the upper receiving member 35 without using a screw.
In short, the fixture may be any member that can restrict the movement of the shaft of the upper base member disposed in the shaft hole of the upper receiving member toward the shaft guide groove.

また、前記各実施形態では、扉3に段部3Aを形成して上部受け部材35を配置していたが、扉3に段部3Aを形成せずに、図13に示すように、扉3の上面に断面L形のエッジ材50を取り付け、このエッジ材50の上に上部受け部材35を固定してもよい。
エッジ材50の立ち上がり片51を、上部受け部材35の屋外側に配置することで上部受け部材35がドア1外部に露出することを防止できる。すなわち、立ち上がり片51を設けることで、ドア枠2の上枠4と立ち上がり片51との隙間の高さ寸法(室外チリ寸法)を小さくでき、意匠性および防犯性を向上できる。
また、上枠4として、断面L形の枠材を用い、室内側に立ち下がり片4Aを配置することで、室内側からも上部受け部材35を視認し難くでき、ドア1の室内面の意匠性も向上できる。
Moreover, in each said embodiment, although the step part 3A was formed in the door 3 and the upper receiving member 35 was arrange | positioned, as shown in FIG. An edge member 50 having an L-shaped cross section may be attached to the upper surface of the upper member, and the upper receiving member 35 may be fixed on the edge member 50.
By arranging the rising piece 51 of the edge member 50 on the outdoor side of the upper receiving member 35, it is possible to prevent the upper receiving member 35 from being exposed to the outside of the door 1. That is, by providing the rising piece 51, the height dimension (outdoor dust size) of the gap between the upper frame 4 of the door frame 2 and the rising piece 51 can be reduced, and the design and crime prevention can be improved.
Further, by using a frame material having an L-shaped cross section as the upper frame 4 and arranging the falling pieces 4A on the indoor side, it is difficult to visually recognize the upper receiving member 35 from the indoor side, and the design of the indoor surface of the door 1 Can also be improved.

軸孔36の形状は、前記実施形態に限定されない。
たとえば、図14に示す軸孔26Cのように、フラット部262が下部受け部材25の高さ方向のほぼ中央に形成され、孔部261および第2孔部263の軸方向の長さがほぼ一致するように形成してもよい。この場合も、図14(A)に示すように、各孔部261、第2孔部263をテーパー状に形成しているので、鉛直軸23に対して下部受け部材25を傾けることができる。そして、図14(B)に示すように、下部受け部材25を水平に戻した際に、扉3を回転すると、高さ方向の中央のフラット部262によって、下部受け部材25つまり扉3が案内される。
The shape of the shaft hole 36 is not limited to the above embodiment.
For example, a flat portion 262 is formed at substantially the center in the height direction of the lower receiving member 25 as in the shaft hole 26C shown in FIG. 14, and the axial lengths of the hole portion 261 and the second hole portion 263 are substantially the same. You may form so that it may do. Also in this case, as shown in FIG. 14A, each hole 261 and second hole 263 are formed in a tapered shape, so that the lower receiving member 25 can be inclined with respect to the vertical shaft 23. 14B, when the door 3 is rotated when the lower receiving member 25 is returned to the horizontal position, the lower receiving member 25, that is, the door 3 is guided by the flat portion 262 at the center in the height direction. Is done.

さらに、図15に示す軸孔26Dのように、下側から順に、孔部261、フラット部262、第2孔部263を形成してもよい。この場合も、図15(A)に示すように、各孔部261、第2孔部263をテーパー状に形成しているので、鉛直軸23に対して下部受け部材25を傾けることができる。そして、図15(B)に示すように、下部受け部材25を水平に戻した際に、扉3を回転すると、高さ方向の上部側のフラット部262によって、下部受け部材25つまり扉3が案内される。
また、軸孔としては、フラット部262を有さずに、軸孔全体がテーパー状に形成されていてもよい。
Furthermore, you may form the hole part 261, the flat part 262, and the 2nd hole part 263 sequentially from lower side like axial hole 26D shown in FIG. Also in this case, as shown in FIG. 15A, each hole 261 and second hole 263 are formed in a tapered shape, so that the lower receiving member 25 can be inclined with respect to the vertical shaft 23. As shown in FIG. 15B, when the lower receiving member 25 is returned to the horizontal position and the door 3 is rotated, the lower receiving member 25, that is, the door 3 is moved by the upper flat portion 262 in the height direction. Guided.
Further, as the shaft hole, the entire shaft hole may be formed in a tapered shape without having the flat portion 262.

さらに、下部ヒンジ装置20および上部ヒンジ装置30としては、ドア枠2側に下部ベース部材21、上部ベース部材31が取り付けられ、扉3側に下部受け部材25、上部受け部材35が取り付けられたものに限定されない。
すなわち、ドア枠2側に、下部受け部材25や上部受け部材35が取り付けられ、扉3側に下部ベース部材21や上部ベース部材31が取り付けられたものでもよい。
図16に示すように、下枠5に下部受け部材25が取り付けられ、扉3の下面に下部ベース部材21が取り付けられた場合も、下部受け部材25の軸孔26がテーパー状の孔部261を備えていることで、下部ベース部材21が固定された扉3を傾けて配置できる。
Further, as the lower hinge device 20 and the upper hinge device 30, a lower base member 21 and an upper base member 31 are attached to the door frame 2 side, and a lower receiving member 25 and an upper receiving member 35 are attached to the door 3 side. It is not limited to.
That is, the lower receiving member 25 and the upper receiving member 35 may be attached to the door frame 2 side, and the lower base member 21 and the upper base member 31 may be attached to the door 3 side.
As shown in FIG. 16, when the lower receiving member 25 is attached to the lower frame 5 and the lower base member 21 is attached to the lower surface of the door 3, the shaft hole 26 of the lower receiving member 25 is a tapered hole portion 261. The door 3 to which the lower base member 21 is fixed can be inclined and arranged.

また、前記各実施形態では、軸案内溝38、38A、38Bの端部に、鉛直軸33を係止するための突起381を形成していたが、この突起381は設けなくてもよい。
さらに、軸案内溝38、38A、38Bは、平面L字状やJ字状に形成されたものに限定されず、たとえば、直線状つまり平面I字状に形成されていてもよい。
これらの構成であっても、固定具で鉛直軸33を保持することで、鉛直軸33つまり扉3がドア枠2から外れることを防止できる。
Moreover, in each said embodiment, although the protrusion 381 for latching the vertical axis | shaft 33 was formed in the edge part of the shaft guide groove 38, 38A, 38B, this protrusion 381 does not need to be provided.
Furthermore, the shaft guide grooves 38, 38A, and 38B are not limited to those formed in a plane L shape or a J shape, and may be formed in a straight line shape, that is, a plane I shape, for example.
Even if it is these structures, it can prevent that the vertical axis | shaft 33, ie, the door 3, remove | deviates from the door frame 2 by hold | maintaining the vertical axis | shaft 33 with a fixing tool.

下部受け部材25は、対向面251にリング状の突起部28を形成していたが、リング状に連続せずに、複数の円弧状に分割された突起部を形成してもよい。
さらに、下部受け部材25は、突起部28を備えていなくてもよい。この場合、下部受け部材25は、対向面251全面で下部ベース部材21に接触するため、回動時の抵抗は増加するが、扉3の自重を広い面積で支持できる利点がある。
In the lower receiving member 25, the ring-shaped protrusions 28 are formed on the facing surface 251, but instead of being continuous in a ring shape, protrusions divided into a plurality of arcs may be formed.
Furthermore, the lower receiving member 25 does not have to include the protruding portion 28. In this case, since the lower receiving member 25 is in contact with the lower base member 21 over the entire opposing surface 251, resistance during rotation increases, but there is an advantage that the weight of the door 3 can be supported over a wide area.

前記実施形態では、上部受け部材35が取り付けられる段部3Aを、扉3上面において、室内側から室外側まで連続して形成していたが、室外側に立ち上がり部を残して段部を形成してもよい。この場合、上部受け部材35が扉3の室外側に露出せず、意匠性、防犯性をより向上できる。
本発明の建具は、玄関ドアに限らず、勝手口ドア、浴室ドア、室内ドアなど、ピポットヒンジ装置で扉3を支持するドアに広く利用できる。さらに、ドアに限らず、鉛直軸(縦軸)を回転軸とするスイング系の開き窓や、折戸、折りたたみ窓など、回転軸が鉛直方向の障子を有する各種建具に適用できる。
また、建物の開口部としては、前記実施形態のドア枠2のように障子を囲む枠体を設けて開口部とするものに限らず、枠体を設けずに壁の開口および床で囲まれる開口を直接開口部としてもよい。この場合、上部ヒンジ装置は、壁に形成された開口部の上面と障子上面との間に設けられ、下部ヒンジ装置は、開口部の下面となる床面と障子下面との間に設けられる。
In the embodiment, the step portion 3A to which the upper receiving member 35 is attached is continuously formed on the upper surface of the door 3 from the indoor side to the outdoor side. However, the step portion is formed on the outdoor side while leaving the rising portion. May be. In this case, the upper receiving member 35 is not exposed to the outdoor side of the door 3, and the design and crime prevention can be further improved.
