Description

本発明は、家具や建具等に設けられる扉体を開閉するための開き戸用蝶番に関するものである。   The present invention relates to hinges for hinged doors for opening and closing doors provided in furniture, joinery and the like.

開き戸用蝶番において、当該開き戸用蝶番のケース体及び第１取付プレートが、例えば家具の固定部材に位置決めして配設され、また、第２取付プレートが、例えば家具の扉体に位置決めして配設されるものであって、固定部材に対する扉体の前後方向の調整及び固定部材に対する扉体の左右方向の調整の両方を行えるようにしたものが従来からある（特許文献１）。
図５，６に示すように、特許文献１の扉開閉装置（開き戸用蝶番）１００は、ケース体１０１及び第１取付プレート１０２が固定部材Ｐに位置決めして配設され、また、第２取付プレート１０３が扉体Ｑに位置決めして配設され、第１取付プレート１０２と第２取付プレート１０３とが付設部材１０４を介して連設されているものである。
このような扉開閉装置１００において、前後方向の調整は、ケース体１０１の大長円１０１ｃ１に配設されるカム本体１０５ａと、その径大軸を第１取付プレート１０２の嵌合孔１０２ｄに嵌合させるとともに、その径小軸に垂下された下軸をカム本体１０５ａの偏心孔に圧入してなるカム操作部１０５ｂとからなるカム１０５を用いて行う。具体的には、カム操作部１０５ｂをドライバ等の操作具で適宜方向に回転させると、カム本体１０５ａが偏心して回転するために、取付プレート１０２は、ケース体１０１の基部１０１ａの底板上を前後方向（図６中の矢印方向）に移動するので、上記前後方向の調整が可能になる。また、左右方向の調整は、ケース体１０１のネジ孔１０１ｄに螺合し、その首下が取付プレート１０２の長溝１０２ｃの突条受け１０２ｃ１に係止される調整ボルト１０６を用いて行う。具体的には、ドライバ等の操作具で調整ボルト１０６を適宜方向に進退させると、調整ボルト１０６の進退に伴って取付プレート１０２は、連結部材１０７の位置を支点として図７中の矢印方向に揺動するので、上記左右方向の調整が可能になる。このとき、取付プレート１０２は、取付プレート１０４から荷重を受けるが、この荷重を連結部材１０７で支持する。かかる連結部材１０７は、当該連結部材１０７の鍔部の裏座面が、取付プレート１０２の湾曲部１０２ｇに合わせた円弧状形態をなすとともに、その表面がフラットな平面をなしており、取付プレート１０２の挿通孔１０２ｆから挿入してケース体１０１の挿通孔１０１ｅより突出した部位をカシメて取り付けられている。これら調整完了後は、固定ボルト１０８により、取付プレート１０２はケース体１０１に固定される。 In the hinge for hinged doors, the case body and the first mounting plate of the hinge for hinged door are positioned and arranged on a furniture fixing member, for example, and the second mounting plate is positioned and arranged on a door body of furniture, for example. Conventionally, there is one that can be adjusted both in the front-rear direction of the door body with respect to the fixing member and in the left-right direction of the door body with respect to the fixing member (Patent Document 1).
As shown in FIGS. 5 and 6, the door opening / closing device (the hinge for hinged door) 100 of Patent Document 1 is provided with the case body 101 and the first mounting plate 102 positioned on the fixing member P, and the second mounting The plate 103 is positioned and disposed on the door body Q, and the first mounting plate 102 and the second mounting plate 103 are connected via the attachment member 104.
In such a door opening and closing device 100, adjustment of the longitudinal direction, the cam body 105a disposed in the large oval 101c 1 of the case body 101, the large diameter shaft into the fitting hole 102d of the first mounting plate 102 The cam 105 is composed of a cam operating portion 105b formed by fitting and fitting the lower shaft suspended from the small-diameter shaft into the eccentric hole of the cam body 105a. Specifically, when the cam operation unit 105b is rotated in an appropriate direction with an operation tool such as a driver, the cam body 105a rotates eccentrically, so that the mounting plate 102 moves back and forth on the bottom plate of the base 101a of the case body 101. Since it moves in the direction (arrow direction in FIG. 6), the adjustment in the front-rear direction is possible. Further, the adjustment in the left-right direction is performed using an adjustment bolt 106 that is screwed into the screw hole 101 d of the case body 101 and whose neck is locked to the protrusion 102 c 1 of the long groove 102 c of the mounting plate 102. Specifically, when the adjustment bolt 106 is advanced and retracted in an appropriate direction with an operating tool such as a driver, the attachment plate 102 moves in the direction of the arrow in FIG. 7 with the position of the connecting member 107 as a fulcrum as the adjustment bolt 106 advances and retreats. Since it swings, the adjustment in the left-right direction is possible. At this time, the mounting plate 102 receives a load from the mounting plate 104, and this load is supported by the connecting member 107. The connecting member 107 has an arcuate shape in which the back surface of the flange portion of the connecting member 107 matches the curved portion 102g of the mounting plate 102, and the surface thereof forms a flat plane. A portion protruding from the insertion hole 101e of the case body 101 after being inserted from the insertion hole 102f is caulked and attached. After these adjustments are completed, the mounting plate 102 is fixed to the case body 101 by the fixing bolt 108.

しかしながら、上述した扉開閉装置においては、固定部材に対する扉体の前後方向の調整及び左右方向の調整の両方が可能で、固定ボルトが緩んで外れることがあっても取付プレートがケース体から抜け落ちないために、最悪の場合に扉体が落下する危険が回避されているが、この抜け落ち防止が、上述のように連結部材のカシメによって結果的に得られているものであることに加え、この対をなす連結部材に対するそれぞれのカシメ具合によってこれら連結部材に遊び（遊びは、取付プレートの所定範囲での左右方向の移動が可能なように設けられる。）の差が生じそのため取付プレートに対する正確な左右調整ができなくなり、その結果、固定部材に対する扉体の左右調整の建付けが正確にできなくなるという不具合が生ずる場合がある。また、この扉開閉装置における左右調整では、取付プレートの左右の揺動量がケース体の基部の底板面に接する当該取付プレートの湾曲部での揺動量に因っているために調整量を大きくすることが難しいという不具合がある。
特開２００８−１５７０２３（第７〜９頁、図５〜８） However, in the door opening and closing device described above, both the front-rear direction adjustment and the left-right direction adjustment of the door body with respect to the fixing member are possible, and the mounting plate does not fall out of the case body even if the fixing bolt loosens and comes off. For this reason, the danger of the door body falling in the worst case is avoided, but in addition to the fact that this prevention of falling out is obtained by caulking of the connecting member as described above, Due to the respective caulking conditions with respect to the connecting members, there is a difference in play (play is provided so that the mounting plate can be moved in the left-right direction within a predetermined range). Adjustment may not be possible, and as a result, there may be a problem that the right / left adjustment of the door to the fixed member cannot be accurately established. Further, in the left / right adjustment in the door opening / closing apparatus, the amount of swinging of the mounting plate is increased because the amount of swinging of the mounting plate is due to the swinging amount of the curved portion of the mounting plate in contact with the bottom plate surface of the base of the case body. There is a problem that it is difficult.
JP2008-157023 (7th to 9th pages, FIGS. 5 to 8)

解決しようとする問題点は、固定部材に対する扉体の前後方向の調整及び左右方向の調整の両方が可能で、固定ボルトが緩んで外れることがあっても取付プレートがケース体から抜け落ちることがない従来の利点を備えつつ、正確な左右方向の調整による建付けを可能とし、且つ、左右方向の調整に際しての調整量を大きくできる構造のものとする点である。   The problem to be solved is that both the front-rear and left-right adjustments of the door body with respect to the fixing member are possible, and the mounting plate does not fall out of the case body even if the fixing bolts loosen and come off While having the advantages of the prior art, it is possible to construct with accurate horizontal adjustment and to have a structure that can increase the adjustment amount in the horizontal adjustment.

本発明の請求項１に係る開き戸用蝶番は、固定部材側に配設されるケース体及び第１取付プレートと、扉体側に配設される第２取付プレートとを備え、前記第１取付プレートと第２取付プレートとが付設部材を介して連設される開き戸用蝶番において、前記ケース体を前記固定部材に固着させ、前記第１取付プレートを前記ケース体に対し前記固定部材に対する前記扉体の前後方向の調整が行えるように当該方向に移動可能に配設し、更に、前記ケース体に、前記扉体からの左右方向の荷重が前記第１取付プレートに付与されたときにこの荷重に応じて前記第１取付プレートを左右方向に揺動させてこの方向の調整を行えるように当該第１取付プレートの所定位置を支持する突起部を立設し、この突起部の両端から上方にそれぞれ延出して互いに対峙する向きに折曲され、且つ、この折曲部の隙間に挿通される前記第１取付プレートとの間に所要のクリアランスが形成されてなる略Ｌ字状ガイド部を設けてなるものであり、前記第１取付プレートの板状部で、当該第１取付プレートの前記ガイド部への挿通が完了したとき当該ガイド部と対峙するところに、当該ガイド部の幅長より所要の幅広で、且つ、適宜な溝深さの、当該ガイド部に臨んで開口してなる切欠溝部を形成し、前記第１取付プレートの前記ガイド部への挿通が完了した後に、当該第１取付プレートと当該ガイド部との間に所要のクリアランスを形成しつつ、前記第１取付プレートの前後方向への移動の制限として前記ガイド部が前記切欠溝部の側壁に係止されるように当該ガイド部を変形してなることを特徴とする。 The hinge for hinged doors according to claim 1 of the present invention includes a case body and a first mounting plate disposed on the fixed member side, and a second mounting plate disposed on the door body side, and the first mounting plate In the hinge for hinged doors, in which the first mounting plate is fixed to the fixing member, and the first mounting plate is fixed to the fixing member with respect to the fixing member. It is arranged to be movable in that direction so that it can be adjusted in the front-rear direction, and further, when a load in the left-right direction from the door body is applied to the first mounting plate, the load is applied to the case body. Accordingly, protrusions that support a predetermined position of the first mounting plate are erected so that the first mounting plate can be swung in the left-right direction and adjusted in this direction. Extend A substantially L-shaped guide portion is provided in which a required clearance is formed between the first mounting plate and the first mounting plate that is bent in a direction opposite to the bent portion and inserted into the gap between the bent portions. Yes, in the plate-like portion of the first mounting plate, when the insertion of the first mounting plate into the guide portion is completed, the width of the guide portion is larger than the width of the guide portion. In addition, a notch groove portion having an appropriate groove depth and opening toward the guide portion is formed, and after the insertion of the first attachment plate into the guide portion is completed, the first attachment plate and the guide The guide part is deformed so that the guide part is locked to the side wall of the notch groove part while restricting movement of the first mounting plate in the front-rear direction while forming a required clearance with the part. It is characterized by

これにより、固定部材に対する扉体の前後方向の調整及び左右方向の調整の両方が可能で、固定ボルトが緩んで外れることがあっても第１取付プレートがケース体から抜け落ちることがない従来の利点を備えつつ、正確な左右調整の建付けが可能となり、且つ、左右調整に際しての調整量を大きくできる。
ところで、本請求項に係る開き戸用蝶番の構造は、経験的に固定部材に対する扉体の左右方向の調整が必要となることが常であることに鑑み、上記所要のクリアランスが形成されていれば、左右方向の調整時に第１取付プレートがガイド部に当接するために第１取付プレートがケース体から抜け落ちることは回避されるという前提をなしているが、左右調整に際しての調整量はある程度制限される。
ここで、上記左右方向の調整や前後方向とは、枠体と扉体との隙間の調整であり、左右方向は、例えば図３の矢印Ａ １ 又はＡ ２ 方向で、前後方向は、例えば図３の矢印Ｂ １ 又はＢ ２ 方向である。
尚、ケース体及び第１取付プレートが扉体側に配設され、第２取付プレートが固定部材側に配設される開き戸用蝶番についても、同様な構成を採ることができることはもちろんである。
また、確実に第１取付プレートのケース体からの抜け落ちを回避できることに加え、上記切欠溝部の溝深さやカシメの程度によって所要のクリアランスを形成することができるので、これを左右方向の調整に際して見込まれる調整量に応じて設定することができる。
上記所要のクリアランスの最大値は、固定部材に対する扉体の左右方向の調整に対応する第１取付プレートの移動から経験的に見積もられる。 Thereby, both the front-rear direction adjustment and the left-right adjustment of the door body with respect to the fixing member are possible, and the first mounting plate does not fall out of the case body even if the fixing bolt loosens and comes off. In this way, it is possible to construct an accurate left / right adjustment and to increase the adjustment amount for the left / right adjustment.
By the way, the structure of the hinge for hinged doors according to the present claim is empirically required to adjust the door body in the left-right direction with respect to the fixing member, so that the required clearance is formed. Although it is assumed that the first mounting plate is prevented from falling out of the case body because the first mounting plate abuts against the guide portion during the left-right adjustment, the amount of adjustment during the left-right adjustment is limited to some extent. The
Here, the adjustment in the left-right direction and the front-rear direction are adjustments of the gap between the frame body and the door body. The left-right direction is, for example, the direction of arrow A 1 or A 2 in FIG. 3 arrow B 1 or B 2 direction.
Of course, the same structure can be adopted for the hinge for the hinged door in which the case body and the first mounting plate are disposed on the door body side, and the second mounting plate is disposed on the fixing member side.
In addition to reliably preventing the first mounting plate from falling out of the case body, the required clearance can be formed depending on the groove depth and the degree of caulking of the notch groove, which is expected when adjusting in the left-right direction. It can be set according to the adjustment amount.
The maximum value of the required clearance is empirically estimated from the movement of the first mounting plate corresponding to the adjustment of the door body in the left-right direction with respect to the fixing member.

本発明の開き戸用蝶番は、固定部材に対する扉体の前後方向の調整及び左右方向の調整の両方が可能で、固定ボルトが緩んで外れることがあっても取付プレートがケース体から抜け落ちることがない従来の利点を備えつつ、正確な左右方向の調整の建付けを可能とし、且つ、この方向の調整に際しての調整量を大きくできる利点がある。   The hinge for hinged doors of the present invention can be adjusted both in the front-rear direction and in the left-right direction of the door body with respect to the fixing member, and the mounting plate does not fall out of the case body even if the fixing bolt is loosened and removed. While having the advantages of the prior art, there is an advantage that an accurate adjustment in the left-right direction is possible, and an adjustment amount in the adjustment in this direction can be increased.

第１取付プレート３をケース体２のガイド部２ｂ１によって形成されたコ字状隙間に挿通させて（図４（Ｂ）の（ａ）参照）、例えば固定ボルト７のために設けられた当該ケース体２のネジ孔２ｅと当該第１取付プレート３の長円３ｅとが連通するようにケース体２に重ね合わせる。このとき、ケース体２の突起部２ｂによって第１取付プレート３の所定位置が均等に支持される態様をなす。したがって、従来の扉開閉装置と比べて正確な左右方向の調整の建付けが可能となる。そして、第１取付プレート３の切欠溝部３ｆにおける溝底３ｆ１とガイド部２ｂ１との間に所要のクリアランスを形成しつつ、ガイド部２ｂ１が切欠溝部３ｆの側壁に係止可能なように当該ガイド部２ｂ１をカシメる（図４（Ｂ）の（ｂ）参照）。この場合のクリアランスは、上述したように左右方向の調整に際して見込まれる調整量に応じて設定されるものであり、したがって、左右方向の調整に際しての調整量を大きくすることも可能となることに加え、第１取付プレート３のケース体２からの抜落ち防止ともなる。 Next, how to assemble the first mounting plate 3 to the case body 2 of the hinge 1 and how to adjust in the left-right direction and in the front-rear direction will be described.
The first mounting plate 3 is inserted through a U-shaped gap formed by the guide portion 2b 1 of the case body 2 (see (a) of FIG. 4B), and for example, for the fixing bolt 7 The case body 2 is superposed on the case body 2 so that the screw hole 2e of the case body 2 and the ellipse 3e of the first mounting plate 3 communicate with each other. At this time, a predetermined position of the first mounting plate 3 is evenly supported by the protrusion 2b of the case body 2. Therefore, it is possible to construct a correct adjustment in the left-right direction as compared with the conventional door opening and closing device. Then, while forming a predetermined clearance between the groove bottom 3f 1 and the guide portion 2b 1 of the first mounting plate 3 of the cutaway groove portion 3f, so that the guide portion 2b 1 is to be locked to the side walls of the cutout groove 3f The guide portion 2b 1 is crimped (see (b) of FIG. 4B). As described above, the clearance in this case is set according to the adjustment amount that is expected in the adjustment in the left-right direction, and therefore, the adjustment amount in the adjustment in the left-right direction can be increased. Also, the first mounting plate 3 can be prevented from falling off from the case body 2.

しかる後、左右方向の調整をする場合には、ドライバ等の操作具で調整ボルト７（十字溝が設けられている）を適宜な方向に進退させると、調整ボルト７の進退に伴って第１取付プレート３は、突起部２ｂを支点として図３中の矢印Ａ１又はＡ２方向に揺動する。この揺動によって固定部材に対する扉体の左右方向の調整が可能となる。
また、前後方向の調整をする場合には、ドライバ等の操作具でカム６の本体部６ａ（十字溝が設けられている）を適宜方向に回転させると、カム６の下軸６ｂに対し本体部６ａが偏心して回転するために、第１取付プレート３は、ケース体２の板状部２ａ上を図３中の矢印Ｂ１又はＢ２方向に移動する。この移動によって固定部材に対する扉体の前後方向の調整が可能となる。
尚、固定ボルト８は、左右方向及び前後方向の調整前に、第１取付プレート３の長円３ｅを挿通してケース体２のネジ孔２ｅに仮止め状態にして螺着されるようにしておくことが好ましく、調整が完了したらネジ込んで第１取付プレート３をケース体２に固定し、この後で、ケース体２の円筒状部３ｂを覆う態様で化粧カバー５を装着する。 Thereafter, when adjusting in the left-right direction, the adjustment bolt 7 (provided with a cross groove) is advanced and retracted in an appropriate direction with an operating tool such as a driver, and the first adjustment is made as the adjustment bolt 7 advances and retracts. mounting plate 3 is swung in the arrow a 1 or a 2 direction in FIG. 3 a protrusion 2b as a fulcrum. This swing enables adjustment of the door body in the left-right direction with respect to the fixed member.
When adjusting the front-rear direction, if the main body 6a (provided with a cross groove) of the cam 6 is rotated in an appropriate direction with an operation tool such as a driver, the main body is moved relative to the lower shaft 6b of the cam 6. for part 6a rotates eccentrically, the first mounting plate 3 moves on the plate-like portion 2a of the case body 2 in the arrow B 1 or B 2 direction in FIG. 3. By this movement, the door body can be adjusted in the front-rear direction with respect to the fixed member.
The fixing bolt 8 is inserted into the ellipse 3e of the first mounting plate 3 and temporarily screwed into the screw hole 2e of the case body 2 before adjustment in the left-right direction and the front-rear direction. Preferably, when the adjustment is completed, the first mounting plate 3 is screwed to fix the first mounting plate 3 to the case body 2, and thereafter, the decorative cover 5 is attached so as to cover the cylindrical portion 3 b of the case body 2.

本発明の開き戸用蝶番は、固定部材に対する扉体の前後方向の調整及び左右方向の調整の両方が可能で、固定ボルトが緩んで外れることがあっても取付プレートがケース体から抜け落ちることがない従来の利点を備えつつ、正確な左右方向の調整の建付けが可能で、この方向の調整量を大きくできるので、既存のものに比べ利用価値の高いものと言える。   The hinge for hinged doors of the present invention can be adjusted both in the front-rear direction and in the left-right direction of the door body with respect to the fixing member, and the mounting plate does not fall out of the case body even if the fixing bolt is loosened and removed. While providing the advantages of the conventional technology, it is possible to construct an accurate adjustment in the left-right direction, and the amount of adjustment in this direction can be increased.
