次に、上記の蝶番１について、更に詳しく説明する。
前記の通り、この蝶番１の夫々は、板状の第１取付部１０と、板状の第２取付部２０と、軸３とを備える。扉の上部に設けられる蝶番１も、下部に設けられる蝶番１も同じ構成のもの（同一のもの）である。
但し、上方の蝶番とその下方の蝶番とでは、取付けが上下逆さまになるので、各部の左右は、逆になる。ここでは、扉の上部に取り付けられる蝶番を基準として、蝶番の各部の名称を決定している。即ち、図８〜図１１において、扉の上部に取り付けられる蝶番を示している。 Next, the hinge 1 will be described in more detail.
As described above, each of the hinges 1 includes the plate-shaped first mounting portion 10, the plate-shaped second mounting portion 20, and the shaft 3. The hinge 1 provided at the upper part of the door and the hinge 1 provided at the lower part have the same configuration (the same thing).
However, since the upper hinge and the lower hinge are mounted upside down, the left and right sides of each part are reversed. Here, the name of each part of the hinge is determined based on the hinge attached to the upper part of the door. That is, FIGS. 8 to 11 show hinges attached to the upper part of the door.

図８〜図１１に示す通り、第１取付部１０は、第１取付板１１（この実施の形態において以下第１縦板１１と呼ぶ。）と、第１縦板１１の上部に設けられた第１横板１２とを備える。図８、図９及び図１２は、扉を閉ざした（伸ばした）状態のときに蝶番がとる形態を示し、図１０及び図１１は、扉を開けた（畳んだ）状態のときに蝶番がとる形態を示している。
第１縦板１１の裏面１１ｂは、左側の扉構成板１００の右側面ｆに対応するものである。蝶番１を開いた状態（図１０、図１１）において、第１横板１２の基部１２ａは、第２取付部２０側に向けて、水平に伸びる。
第２取付部２０は、第２取付板２１（この実施の形態において以下第２縦板２１と呼ぶ。）と、第２縦板２１の上部に設けられた第２横板２２とを備える。
第２縦板２１の裏面２１ｂは、右側の扉構成板２００の左側面ｅに対応するものである。扉を畳んだ（開いた）状態（図１０、図１１）において、第２横板２２の基部２２ａは、第１取付部１０側に向けて、水平に伸びる。 As shown in FIGS. 8 to 11, the first mounting portion 10 is provided on a first mounting plate 11 (hereinafter, referred to as a first vertical plate 11 in this embodiment) and an upper portion of the first vertical plate 11. And a first horizontal plate 12. FIGS. 8, 9 and 12 show a form in which the hinge is taken when the door is closed (extended), and FIGS. 10 and 11 show a form in which the hinge is taken when the door is opened (folded). This shows a form to be taken.
The back surface 11b of the first vertical plate 11 corresponds to the right side surface f of the left door component plate 100. In a state where the hinge 1 is opened (FIGS. 10 and 11), the base 12 a of the first horizontal plate 12 extends horizontally toward the second mounting portion 20.
The second mounting portion 20 includes a second mounting plate 21 (hereinafter, referred to as a second vertical plate 21 in this embodiment) and a second horizontal plate 22 provided above the second vertical plate 21.
The back surface 21b of the second vertical plate 21 corresponds to the left side surface e of the right door component plate 200. In a state where the door is folded (opened) (FIGS. 10 and 11), the base 22 a of the second horizontal plate 22 extends horizontally toward the first mounting portion 10.

各取付部１０，２０の、第１と第２の横板１２，２２同士については、一方が他方の上に配置され、両横板１２，２２は、上記軸３にて上下に貫かれている。当該軸３を中心とし第２取付部２０に対して第１取付部１０を回動することにより、第１及び第２の横板１２，２２双方の先端部１２ｂ，２２ｂが重なり第１及び第２の両縦板１１，２１の表面同士が対面し、左右の扉構成板１００，２００を伸ばした状態とすることができる。
図８〜図１１に示す状態において、第１横板１２が第２横板２２の上方に位置する（但し、図８〜図１１に示す状態において、第２横板２２を第１横板１２の上方に位置するよう構成するのを制限するものではない）。 With respect to the first and second horizontal plates 12 and 22 of each of the mounting portions 10 and 20, one is disposed on the other, and both horizontal plates 12 and 22 are vertically penetrated by the shaft 3. I have. By rotating the first mounting portion 10 with respect to the second mounting portion 20 about the shaft 3, the tip portions 12 b and 22 b of both the first and second horizontal plates 12 and 22 are overlapped, and the first and second horizontal plates 12 and 22 are overlapped. The surfaces of the two vertical plates 11 and 21 face each other, and the left and right door constituting plates 100 and 200 can be extended.
In the state shown in FIGS. 8 to 11, the first horizontal plate 12 is located above the second horizontal plate 22 (however, in the state shown in FIGS. 8 to 11, the second horizontal plate 22 is ).

上記の構成板１００，２００において、各受容部４，４の深さは、各縦板１０，２０の厚み（表面１１ａ，２１ａと裏面１１ｂ，２１ｂの間の幅）よりも大きく、また、図７に示す通り、各受容部４，４内の前後の幅ｔ１，ｔ２は、夫々、縦板１０，２０の前後の幅ｍ１，ｍ２よりも大きいか、これと等しい。
これにて、図４〜図７へ示す通り、蝶番１の、第１取付部１０が備える第１縦板１０は、左構成板１００の受容部４内に収容され、ネジやボルトなどの固定具で、左構成板１００の右側面ｆに固定される。同様に、第２取付部２０が備える第２縦板２０は、右構成板２００の受容部４内に収容され、ネジやボルトなどの固定具で、右構成板２００の左側面ｅに固定される。
この際に、上記の非被覆部６，６から、第１及び第２の横板１２，２２を外部ヘ露出させることができ、被覆部４，４が邪魔にならない。
図５及び図６に示すように、上記の非被覆部６，６を、両構成板の左右側面ｅ，ｆの最上部及び最下部に形成しておく。これにて、蝶番を両扉構成板１００，２００の側面の、最上部及び最下部に固定することができる。即ち、このような構成により、第１及び第２の両横板１２，２２を、両扉構成板１００，２００の上面と同じ位置かそれより上方、或いは両扉構成板１００，２００の下面と同じ位置かそれより下方に、配置することができ、これにて蝶番を更に目立たなくすることができ、扉の美観をより一層向上し得た。 In the constituent plates 100 and 200 described above, the depth of each of the receiving portions 4 and 4 is larger than the thickness of each of the vertical plates 10 and 20 (the width between the front surfaces 11a and 21a and the back surfaces 11b and 21b). As shown in FIG. 7, the front and rear widths t1 and t2 in each of the receiving portions 4 and 4 are larger than or equal to the front and rear widths m1 and m2 of the vertical plates 10 and 20, respectively.
Thus, as shown in FIGS. 4 to 7, the first vertical plate 10 of the hinge 1, which is provided in the first mounting portion 10, is accommodated in the receiving portion 4 of the left component plate 100, and fixed with screws or bolts. And is fixed to the right side surface f of the left component plate 100. Similarly, the second vertical plate 20 included in the second mounting portion 20 is housed in the receiving portion 4 of the right component plate 200 and fixed to the left side surface e of the right component plate 200 by a fixing tool such as a screw or a bolt. You.
At this time, the first and second horizontal plates 12 and 22 can be exposed to the outside from the uncovered portions 6 and 6, and the covered portions 4 and 4 do not interfere.
As shown in FIGS. 5 and 6, the above-mentioned uncovered portions 6 and 6 are formed on the uppermost and lowermost portions of the left and right side surfaces e and f of both constituent plates. Thus, the hinges can be fixed to the uppermost and lowermost portions of the side surfaces of the two-door component plates 100 and 200. In other words, with such a configuration, the first and second horizontal plates 12 and 22 are positioned at the same position as or above the upper surfaces of the two door component plates 100 and 200, or with the lower surfaces of the two door component plates 100 and 200. It could be placed at the same position or below, which could make the hinge less noticeable and could further enhance the aesthetics of the door.

図１２へ示す通り、この蝶番１には、扉をのばした状態（閉ざした状態）に固定する固定機構７が設けられている。
詳しくは、第１及び第２の横板１２，２２の両先端部の重なる面について、一方の面には凹み部７０が設けられ、他方の面には出没可能な突起７１と当該突起を露出する方向に押圧するバネ等の弾性体７２とが備えられている。第１及び第２の横板１２，２２双方の先端部１２ｂ，２２ｂを重ねた際、上記弾性体の付勢で凹み部に突起が押し込まれることにより、第１及び第２の両縦板１１，２１の表面同士が対面した状態に固定されるものである。 As shown in FIG. 12, the hinge 1 is provided with a fixing mechanism 7 for fixing the door in an extended state (closed state).
More specifically, a concave portion 70 is provided on one surface of the overlapping surfaces of the two distal end portions of the first and second horizontal plates 12 and 22, and the other surface is provided with a protrusion 71 that can appear and disappear, and the protrusion is exposed. And an elastic body 72 such as a spring that presses in the direction in which the spring is pressed. When the tip portions 12b and 22b of both the first and second horizontal plates 12 and 22 are overlapped, the projections are pushed into the recesses by the bias of the elastic body, so that the first and second vertical plates 11 and 22 are pressed. , 21 are fixed such that their surfaces face each other.

上記の通り、この固定機構７は、上記の凹み部７０（請求項４の凹部に対応する。）と、突起７１と、弾性体７２とを有する。この実施の形態では、突起７１は、球である。また、固定機構７は、第２横板２２に上下に伸びる雌ねじ７４が形成され、当該雌ねじ７４に螺合する雄ねじを外周に備えた別途の調整部材７３を有する。そして、当該調整部材７３に上記突起７１と弾性体７２とが収容されている。調整部材７３を回すことによって、雌ねじ７４に対して、調整部材７３は上下に位置を変えることができ、上記突起７１の凹み部７０内への押し込みの強さを調整することができる（請求項４の凸部は、この実施の形態において、上記の突起７１と、弾性体７２と、調整部材７３にて構成されている）。また、この雌ねじ７４には、外部に通じる副雌ねじ７５が連絡している。この副雌ねじ７５内には、当該副雌ねじ７５に螺合する雄ねじを外周に備えた固定部材７６が装着されている。この固定部材７６は、外部からレンチやドライバなどの固定手段（締め付け工具）を用いて回することによって、副雌ねじ７５内を、雌ねじ７４側に向けて移動させることができる。このような移動にて、雌ねじ７４内の調整部材７３に固定部材７６を押しつけることで、上記の調整部材７３の位置を固定することができ、長期の使用によっても、突起７１の押し込みが緩むのを抑制することができる。 As described above, the fixing mechanism 7 includes the recess 70 (corresponding to the recess of claim 4), the protrusion 71, and the elastic body 72. In this embodiment, the projection 71 is a sphere. Further, the fixing mechanism 7 has a separate adjusting member 73 in which a female screw 74 extending vertically is formed on the second horizontal plate 22, and having a male screw on the outer periphery that is screwed to the female screw 74. The projection 71 and the elastic body 72 are accommodated in the adjustment member 73. By turning the adjusting member 73, the adjusting member 73 can be moved up and down with respect to the female screw 74, and the strength of pushing the projection 71 into the recess 70 can be adjusted. In this embodiment, the projection 4 is composed of the projection 71, the elastic body 72, and the adjustment member 73). The female screw 74 is in communication with a sub female screw 75 communicating with the outside. In the sub female screw 75, a fixing member 76 having an external thread on the outer periphery to be screwed to the sub female screw 75 is mounted. The fixing member 76 can be moved toward the female screw 74 in the sub female screw 75 by turning the fixing member 76 from outside using a fixing means (a tightening tool) such as a wrench or a screwdriver. By pressing the fixing member 76 against the adjusting member 73 in the female screw 74 by such movement, the position of the adjusting member 73 can be fixed, and the pushing of the protrusion 71 is loosened even after long-term use. Can be suppressed.

また、第１及び第２の横板１２，２２に設けることで、扉構成板１００，２００の側面に配置される第１及び第２の縦板１１，１２から、このような固定機構７を排除可能とした。これにて、蝶番が開いたとき扉を閉じた（伸ばされた）状態とするために、第１取付部１０（の縦板１１）を左側の扉構成板１００の右側面に、第２取付部２０（の縦板２１）を右側の扉構成板２００の左側面に取り付けても、取付部１０，２０（の縦板）同士の対面が、当該固定機構７によって邪魔されない。 Further, by providing the first and second horizontal plates 12 and 22, such a fixing mechanism 7 can be formed from the first and second vertical plates 11 and 12 disposed on the side surfaces of the door component plates 100 and 200. It can be excluded. Thus, in order to make the door closed (extended) when the hinge is opened, the first mounting portion 10 (the vertical plate 11 thereof) is attached to the right side surface of the left door component plate 100 by the second mounting portion. Even when the (vertical plate 21) of the portion 20 is attached to the left side surface of the door configuration plate 200 on the right side, the facing of the attachment portions 10, 20 (the vertical plate) is not obstructed by the fixing mechanism 7.

ここで、上記図１乃至図１２へ示す実施の形態に採用した蝶番について、更に詳しく述べる。
上述の通り、第１及び第２の取付部１０，２０の夫々は、扉構成板１００，２００の側面に取り付けられる（第１及び第２の）縦板１１，２１と、縦板１１，２１の上端と下端の何れか一方にのみ設けられた（第１及び第２の）横板１２，２２とにて構成される。

As described above, the first and second mounting portions 10 and 20 are respectively attached to the side surfaces of the door component plates 100 and 200 (the first and second) vertical plates 11 and 21 and the vertical plates 11 and 21. And (first and second) horizontal plates 12 and 22 provided only on one of the upper end and the lower end of the horizontal direction.
The back surfaces of the individual vertical plates 11 and 21 are attached to the side surfaces of the door constituting plates 100 and 200.
Each of the horizontal plates 12 (22) has a tip extending horizontally from the surface of the vertical plate 11 (21) toward the vertical plate 21 (11) of the other mounting portion in a state where the door is extended (the door is closed). A portion 12b (22b) and a base portion 12a (22a) that is located on the front side or the rear side of the door with respect to the front end portion 12b (22b) and horizontally disposed. In the embodiment shown in FIGS. 1 to 12, when the door is extended, the bases 12a and 22a are located on the front side of the door with respect to the tips 12b and 22b.
The base 12 a of the (first) horizontal plate 12 is placed above or below the base 22 a of the (second) horizontal plate 22, and is fixed by the shaft 3. When the door is folded (when the door is opened), the tip of one horizontal plate is separated from the tip of the other horizontal plate by rotating about the shaft 3.

具体的には、上記の先端部１２ｂ，２２ｂの夫々は、平面視略矩形の板状体であり、基部１２ａ，２２ａの夫々は、平面視略円弧状の板状体である。扉を伸ばした状態（扉を閉じた状態）、即ち、横板１２，２２（の先端部１２ｂ，２２ｂ）を重ねた（閉じた）状態を基準として、横板１２，２２の先端部１２ｂ，２２ｂの夫々は、図８（Ｂ）へ示す通り、背面１３，２３と、左側面１４，２４と、右側面１５，２５と、上面１６，２６と、下面１７，２７とを備える（説明の便宜上、扉を伸ばした状態を基準として、横板１２，２２各部の名称を決定しているが、以下において、横板１２，２２の開閉の状態の変化によっても、これらの名称を用いるものとする）。
図１〜１２に示す実施の形態において、第１横板１２が第２横板２２の上に位置し、上記の固定機構７の凹み部２２は、第１横板１２の下面１７に形成され、雌ねじ７４は、第２横板２２に設けられている。雌ねじ７４は、第２横板２２の下面２７から上面２６にかけて形成されている。この雌ねじ７４に、前述の調整部材７３が収容されているのである。
また、第２横板２２の背面２３に、雌ねじ７４に連絡する副雌ねじ７５の開口部が形成されている。 Specifically, each of the above-mentioned tip portions 12b and 22b is a plate-like body having a substantially rectangular shape in plan view, and each of the base portions 12a and 22a is a plate-like body having a substantially arc shape in plan view. On the basis of the state where the door is extended (the state where the door is closed), that is, the state where the (ends 12b and 22b of) the horizontal plates 12 and 22 are overlapped (closed), the distal ends 12b and As shown in FIG. 8B, each of 22b includes back surfaces 13, 23, left side surfaces 14, 24, right side surfaces 15, 25, upper surfaces 16, 26, and lower surfaces 17, 27 (described in the description). For convenience, the names of the respective parts of the horizontal plates 12, 22 are determined based on the state in which the door is extended, but in the following, these names are also used depending on the change in the open / closed state of the horizontal plates 12, 22. Do).
In the embodiment shown in FIGS. 1 to 12, the first horizontal plate 12 is located on the second horizontal plate 22, and the recess 22 of the fixing mechanism 7 is formed on the lower surface 17 of the first horizontal plate 12. The female screw 74 is provided on the second horizontal plate 22. The female screw 74 is formed from the lower surface 27 to the upper surface 26 of the second horizontal plate 22. The adjusting member 73 is housed in the female screw 74.
Further, an opening of a sub female screw 75 communicating with the female screw 74 is formed on the back surface 23 of the second horizontal plate 22.

以下、蝶番１の他の実施の形態について説明する。
上記の実施の形態において、副雌ねじ７５の開口部を、第２横板２２の背面２３に形成した。即ち、扉を閉じた（扉を伸ばした）状態において、上記の実施の形態では、副雌ねじ７５は、図８に示す通り前後方向に伸び、その一端が第２横板２２の背面２３にて開口するものとした（扉を開いた状態即ち扉を畳んだ状態では、図１１に示す通り、副雌ねじ７５は左右方向に伸びる）。この他、図１３及び図１４に示す通り、副雌ねじ７５の開口部を、第２横板２２の上記左側面２４に形成するものとしても実施可能である。即ち、扉を伸ばした状態において、副雌ねじ７５が伸びる方向を、左右方向とし、当該副雌ねじ７５の一端が第２横板２２の上記左側面２４に開口するものとするのである（扉を開いた状態即ち扉を畳んだ状態では、副雌ねじ７５は前後方向に伸びる）。図１３（Ａ）及び図１４において、副雌ねじ７５とその固定部材７６とは、破線で、透視した状態に描いてある。また、図１３（Ｂ）及び図１４において、雌ねじ７４及び調整部材７３の一部も、破線で、透視した状態に描いてある。
尚、図１３（Ａ）は扉を開いた（扉を畳んだ）状態のときの蝶番１の平面図であり、図１３（Ｂ）はその背面図であり、図１４はその右側面図である。
図５に示す通り、第２横板２２の背面２３に、副雌ねじ７５の開口部を形成した場合、非被覆部６を十分に広く確保しておかないと、副雌ねじ５７内の固定部材７６を螺回する際、扉構成板の当該非被覆部６を画する縁６ａ付近が邪魔になって、螺回に用いるレンチなどの締め付け工具を差し込むのが困難になる。上記の通り、副雌ねじ７５の開口部を、第２横板２２の上記左側面２４に形成することによって、締め付け工具を差し込みの障害となるものがなくなるので、このような問題は回避できる。従って、非被覆部６を極力小さく形成して、蝶番１を目立たせないようにするのに効果的である。 Hereinafter, another embodiment of the hinge 1 will be described.
In the above embodiment, the opening of the sub female screw 75 is formed on the back surface 23 of the second horizontal plate 22. That is, in the state where the door is closed (the door is extended), in the above embodiment, the sub female screw 75 extends in the front-rear direction as shown in FIG. The sub female screw 75 extends in the left-right direction as shown in FIG. 11 when the door is opened, that is, when the door is folded. In addition, as shown in FIGS. 13 and 14, the opening of the sub female screw 75 may be formed in the left side surface 24 of the second horizontal plate 22. That is, in the state where the door is extended, the direction in which the sub female screw 75 extends is the left-right direction, and one end of the sub female screw 75 is opened to the left side surface 24 of the second horizontal plate 22 (open the door). When the door is folded, that is, when the door is folded, the sub female screw 75 extends in the front-rear direction). 13 (A) and FIG. 14, the auxiliary female screw 75 and its fixing member 76 are drawn in broken lines in a see-through state. In FIGS. 13B and 14, a part of the female screw 74 and the adjustment member 73 are also drawn by broken lines in a see-through state.
13A is a plan view of the hinge 1 when the door is opened (the door is folded), FIG. 13B is a rear view thereof, and FIG. 14 is a right side view thereof. is there.
As shown in FIG. 5, when the opening of the sub female screw 75 is formed on the rear surface 23 of the second horizontal plate 22, the fixing member 76 in the sub female screw 57 must be secured unless the uncovered portion 6 is sufficiently widened. When screwing, the vicinity of the edge 6a of the door constituting plate that defines the uncovered portion 6 becomes an obstacle, and it becomes difficult to insert a tightening tool such as a wrench used for screwing. As described above, since the opening of the sub female screw 75 is formed in the left side surface 24 of the second horizontal plate 22, there is no obstacle to the insertion of the fastening tool, so that such a problem can be avoided. Therefore, it is effective to form the uncovered portion 6 as small as possible and to make the hinge 1 inconspicuous.

この図１３及び図１４に示す実施の形態では、第２横板２２（の上記左側面２４）には、当たり部８が設けられている。この当たり部８について説明する。
図９（Ｂ）へ示す通り、第１横板１２を第２横板２２に対して円滑に開閉可能とするために、扉を伸ばした状態即ち、両横板１２，２２を畳んだ状態において、第１縦板１１と第２横板１２との間には、隙間ｚが設けられている。このため、扉を閉じて（扉を伸ばして）、隙間ｚがなくなると、左右の扉構成板１００，２００は、平面視において、一直線（角度１８０度）とならず、幾分扉の正面側に山なり（「く」の字）になる。そこで、上記隙間ｚと同じ幅、第２横板２２の上記左側面２４から突出する突起、即ち、上記の当たり部８を形成しておくのである。このような当たり部８の形成にて、扉を閉じた際、左右の扉構成板１００，２００を一直線に伸ばすことができる。
この図１３及び図１４に示す実施の形態において、当たり部８を、第２横板２２の上記左側面２４に設けるものとしたが、これとは逆に、当たり部８を、第１縦板１１（の右側面）に設けるものとしても実施可能である。この場合、当たり部８は、第２横板２２の上記左側面２４と当接して、扉を閉じた際、左右の扉構成板１００，２００を一直線とすることができる。
尚、図１３及び図１４へ示す実施の形態において、当たり部８、副雌ねじ７５の向き及びその開口部の位置以外の構成については、図１〜図１２に示す実施の形態と同様である。 In the embodiment shown in FIGS. 13 and 14, the second horizontal plate 22 (the left side surface 24) is provided with the contact portion 8. The contact portion 8 will be described.
As shown in FIG. 9B, in order to allow the first horizontal plate 12 to open and close smoothly with respect to the second horizontal plate 22, the door is extended, that is, in a state where both horizontal plates 12, 22 are folded. A gap z is provided between the first vertical plate 11 and the second horizontal plate 12. For this reason, when the door is closed (extended the door) and the gap z is eliminated, the left and right door component plates 100 and 200 do not become a straight line (at an angle of 180 degrees) in a plan view, and are slightly closer to the front side of the door. It becomes a mountain ("ku"). Therefore, a projection which has the same width as the gap z and protrudes from the left side surface 24 of the second horizontal plate 22, that is, the contact portion 8 is formed. With the formation of such a contact portion 8, when the door is closed, the left and right door constituting plates 100 and 200 can be straightened.
