このヒンジHの場合、ヒンジ本体1は、図2に示すように、一対のフック42、軸44、ヒンジピンストッパー491d及びばね部材45を除く主体の部分が亜鉛ダイカストその他の金属材料により一体に形成され、水平断面が略L字形で上下に長く形成されて、一方の部材に取り付けられる取付ベース4と、この取付ベース4が一方の部材に取り付けられた際に一方の部材において内側に向けられる取付ベース4の一方の側部から外側方向に(この場合、およそ60°)斜めに向けて延びるヒンジアーム46と、このヒンジアーム46の先端縁部の上部及び下部にそれぞれ、軸方向を上下に向けて所定の長さの円筒状に形成される上下のヒンジピン挿通部47(47U、47D)とを有し、上下の各ヒンジピン挿通部47間が後述するヒンジ羽根2のヒンジピン挿通部57を連通可能に溝形の間欠部48になっている。
また、このヒンジ本体1の場合、ヒンジアーム46が取付ベース4の一方の側部において縦に長い略長方形状の、全体としてフラットなプレートからなり、一方の部材側に向けられる斜めの側面に、一端を上のピン挿通部47Uの外周面の軸方向中間部所定の位置(この場合、軸方向中央の位置)に取って、他端を下のピン挿通部47Dの外周面の軸方向中間部所定の位置(この場合、軸方向中央の位置)に取って、略コ字形に溝491が形成される。この溝491は一部を除いて細幅で比較的深く形成され、上下の各ヒンジピン挿通部47の位置で外周面から内周面までが切り欠かれて開口される。また、この溝491のうち各ヒンジピン挿通部47の軸方向と直角に延びる両側の各溝491aの一部で各ヒンジピン挿通部47の軸方向と平行に延びる中間の溝491bの両端に近い各一部が少し幅広に形成されてこの幅広の部分に両側の幅細の各溝491aの延長上に沿って一対の突片491cが立ち上がり形成され、各突片491c間に両側の各幅細の各溝491aに連通する溝491aが併せて形成される。この略コ字形の溝491にはヒンジピンストッパー491dが取り付けられる。このヒンジピンストッパー491dは、後述するヒンジピン3にヒンジピン挿通部47内で係合しヒンジピン3を保持するためのもので、金属の線材、この場合、ステンレススチールの線材からなり、ヒンジ本体1の略コ字形の溝491(各一対の突片491c間の溝491aを含む)に嵌合可能に略コ字形に折り曲げられる。このようなヒンジピンストッパー491dが、ヒンジ本体1の略コ字形の溝491(各一対の突片491c間の溝491aを含む)に嵌め込まれ、各一対の突片491cがカシメられて固定され、このヒンジピンストッパー491dの両端側の一部が各ヒンジピン挿通部47の位置で各ヒンジピン挿通部47の内周面内に弦状に通される。
In the case of this hinge H, as shown in FIG. 2, the hinge body 1 is integrally formed of zinc die-cast or other metal material except for the pair of hooks 42, shaft 44, hinge pin stopper 491d and spring member 45. , a mounting base 4 having a substantially L-shaped horizontal cross section and elongated vertically and mounted on one member; and a mounting base directed inward in the one member when the mounting base 4 is mounted on the one member. A hinge arm 46 extending obliquely outwardly (in this case, about 60°) from one side of the hinge arm 4, and an upper and lower portion of the tip edge of the hinge arm 46, respectively, with the axial direction directed up and down. It has upper and lower hinge pin insertion portions 47 (47U, 47D) formed in a cylindrical shape of a predetermined length, and the hinge pin insertion portions 57 of the hinge blades 2 described later can be communicated between the upper and lower hinge pin insertion portions 47. A groove-shaped intermittent portion 48 is formed.
Further, in the case of this hinge body 1, the hinge arm 46 is formed of a vertically elongated substantially rectangular plate on one side of the mounting base 4 and is flat as a whole. One end is held at a predetermined position (in this case, the axial center position) in the axially intermediate portion of the outer peripheral surface of the upper pin insertion portion 47U, and the other end is placed in the axially intermediate portion of the outer peripheral surface of the lower pin insertion portion 47D. A substantially U-shaped groove 491 is formed at a predetermined position (in this case, the central position in the axial direction). The groove 491 is narrow and relatively deep except for a part thereof, and is opened by notching from the outer peripheral surface to the inner peripheral surface at the positions of the upper and lower hinge pin insertion portions 47 . Also, in the grooves 491, each groove 491a on both sides extending perpendicular to the axial direction of each hinge pin insertion portion 47 has a portion close to both ends of an intermediate groove 491b extending parallel to the axial direction of each hinge pin insertion portion 47. A pair of projecting pieces 491c are formed along the extension of the narrow grooves 491a on both sides of this wide portion. A groove 491a communicating with the groove 491a is also formed. A hinge pin stopper 491 d is attached to the substantially U-shaped groove 491 . The hinge pin stopper 491d engages the hinge pin 3 described later in the hinge pin insertion portion 47 to hold the hinge pin 3. It is bent into a substantially U-shape so as to be fitted into the letter-shaped grooves 491 (including the grooves 491a between each pair of projecting pieces 491c). Such a hinge pin stopper 491d is fitted into the substantially U-shaped groove 491 (including the groove 491a between each pair of protruding pieces 491c) of the hinge body 1, and each pair of protruding pieces 491c is crimped and fixed. A part of both ends of the hinge pin stopper 491d is passed through the inner peripheral surface of each hinge pin insertion portion 47 at the position of each hinge pin insertion portion 47 in a chord shape.

かかるヒンジ本体1において、取付ベース4、一対の軸受42、一対のフック43、ばね部材45は次のように構成される。 In the hinge body 1, the mounting base 4, the pair of bearings 42, the pair of hooks 43, and the spring member 45 are constructed as follows.

取付ベース4は、ヒンジアーム46と概ね同様に、縦に長い略長方形状の、全体としてフラットなプレートからなり、ヒンジアーム46側の面とは反対の面が一方の部材の取付プレートに当接可能な平面41になっている。一対の軸受42はそれぞれ、この取付ベース4の平面に一体に、この平面の全周縁部をフランジ411として残すように、取付ベース4の長辺方向中央で各長辺側の縁部41aよりも少し内側に入った位置に各長辺の縁部41aと平行に、所定の長さ、大きさを有する角形に、この場合、略長方形状に、全体としてフラットなプレート状に形成される。また、この場合、取付ベース4の平面41で一対の軸受42間の両端部にそれぞれ凸段状に、ここでは断面略長方形の凸状に、一対のフック43のための受け部412が併せて形成される。そして、各軸受42の突出端421側(つまり、取付ベース4とは反対側の端部側)の上下両側角部の近傍にそれぞれ、軸44を挿通可能な軸挿通部423が穿設される。なお、各軸受42の外側(言い換えれば、外向き)の平面で各軸挿通部423の全周縁部にテーパ状の溝425が併せて形成される。 Like the hinge arm 46, the mounting base 4 consists of a vertically elongated substantially rectangular plate that is flat as a whole. A possible plane 41 is formed. Each of the pair of bearings 42 is integral with the plane of the mounting base 4, and is located at the center of the mounting base 4 in the longitudinal direction so as to leave the entire peripheral edge of this plane as a flange 411, extending from the edges 41a on the long side of the mounting base 4. A rectangular shape having a predetermined length and size, in this case a substantially rectangular shape, is formed in a flat plate shape as a whole, parallel to each long side edge 41a at a slightly inward position. Further, in this case, on the flat surface 41 of the mounting base 4, at both end portions between the pair of bearings 42, there are also stepped receiving portions 412 for the pair of hooks 43. It is formed. A shaft insertion portion 423 through which the shaft 44 can be inserted is formed in the vicinity of both upper and lower corners of each bearing 42 on the protruding end 421 side (that is, on the side opposite to the mounting base 4). . A tapered groove 425 is also formed on the outer (in other words, outward) plane of each bearing 42 along the entire periphery of each shaft insertion portion 423 .

一対のフック43はそれぞれ、一対の軸受42の略長方形の平面の半面内に配置可能な大きさで、この略長方形の平面内で長辺方向中央位置を対称中心として対称的な形状になっている。図3に示すように、これらフック43の回動中心はそれぞれ、各軸受42の突出端421に対応する各フック43の一端の縁部431側で各軸受42の両側縁部422、424に対応する外側一方の側縁部432寄りに設けられて、ここに軸44を挿通可能に軸挿通部430が形成され、取付ベース4側に対応する各フック43の他端の縁部433は円の中心をフック43の回動中心よりもフック43の一端の縁部431に近くかつ内側他方の側縁部434寄りの位置におく円弧状に形成される。 Each of the pair of hooks 43 has a size that allows it to be arranged within the half plane of the substantially rectangular plane of the pair of bearings 42, and has a symmetrical shape within the substantially rectangular plane with the central position in the long side direction as the center of symmetry. there is As shown in FIG. 3 , the center of rotation of these hooks 43 corresponds to both side edges 422 and 424 of each bearing 42 on the edge 431 side of one end of each hook 43 corresponding to the projecting end 421 of each bearing 42 . A shaft insertion portion 430 is formed near one of the outer side edges 432 of the mounting base 4 so that the shaft 44 can be inserted therethrough. It is formed in an arc shape with its center located closer to the edge 431 at one end of the hook 43 and closer to the other inner side edge 434 than the center of rotation of the hook 43 .

また、これらのフック43はそれぞれ、外側一方の側縁部432が軸受42の各側縁部422、424と平行に断面直線状のフラットな面として形成され、一端の縁部431は複合形状で、外側一方の側縁部432側の一部が円の中心をフック43の回動中心におく断面円弧状のフラットな面に形成され、内側他方の側縁部434側の残部がフック43の回動中心を対称中心として外側一方の側縁部432と対称的に斜めにフラットな面として形成され、内側他方の側縁部434は外側一方の側縁部432と平行に又は平行よりも少し開く方向に、ここでは後者の少し開く方向に向けてフラットな面として形成される。
そして、各フック43の他端の縁部433には内側他方の側縁部434側の端部に取付ベース4の各受け部412に係合可能に凸状に、ここでは断面台形状にストッパー435が併せて形成され、取付ベース4の各受け部412と各フック43の各ストッパー435との係合により、各フック43の各軸受42から突出方向への過度の回動、すなわち各フック43の各軸受42からの飛び出しが規制される。
Each of these hooks 43 has an outer one side edge 432 formed as a flat surface with a linear cross section parallel to each side edge 422, 424 of the bearing 42, and one end edge 431 having a compound shape. , a portion on the side of one of the outer side edges 432 is formed into a flat surface having an arcuate cross-section with the center of the circle as the center of rotation of the hook 43 , and the remaining portion on the side of the other inner side edge 434 is formed on the hook 43 . It is formed as a flat surface obliquely symmetrically with one of the outer side edges 432 with the rotation center as the center of symmetry, and the other inner side edge 434 is parallel or slightly less than parallel to the one outer side edge 432 . It is formed as a flat surface in the direction of opening, here in the direction of slightly opening the latter.
At the edge 433 of the other end of each hook 43, the end on the other side edge 434 side of the hook 43 has a protruding stopper so as to be able to engage with each receiving portion 412 of the mounting base 4. Here, the stopper has a trapezoidal cross section. 435 are also formed together, and the engagement between each receiving portion 412 of the mounting base 4 and each stopper 435 of each hook 43 causes each hook 43 to rotate excessively from each bearing 42 in the projecting direction, that is, each hook 43 is regulated from jumping out of each bearing 42.

ばね部材45はコイルスプリングが採用される(以下、コイルスプリング45という。)。この場合、図2に示すように、各フック43の内側他方の側縁部434に円筒状の孔436が形成され、コイルスプリング45は両端を各フック43の孔436に保持されて各フック43間に介装される。また、この場合、各フック43の孔436は、図3に示すように、このヒンジ本体1が一方の部材の取付プレートの取付孔に取り付けられる際に一対の軸受42が各フック43とともに取付プレートの取付孔に通される前又は後で各フック43の各係止爪43Aが各軸受42の両側縁部422間、424間から突出されたときにコイルスプリング45を取付ベース4側に凸の円弧状に変形案内可能に、各フック43の内側他方の側縁部434の面に対して所定の角度を付けて形成され、かつこの孔436のフック43の他端の縁部433側の内周面の一部437が、一対の軸受42が各フック43とともに一方の部材の取付プレートの取付孔に通され各フック43の各係止爪43Aが各軸受42の両側縁部422間、424間に没入されたときにコイルスプリング45を取付プレート4とは反対側に凸の円弧状に変形案内可能に、孔436の奥側から開口側に向けて漸次拡径される所定の角度の傾斜を付けて形成される。 A coil spring is employed as the spring member 45 (hereinafter referred to as a coil spring 45). In this case, as shown in FIG. 2, a cylindrical hole 436 is formed in the other inner side edge 434 of each hook 43 , and both ends of the coil spring 45 are held in the holes 436 of each hook 43 . interposed in between. Also, in this case, the holes 436 of each hook 43, as shown in FIG. Before or after the hooks 43 are passed through the mounting holes, the coil springs 45 are projected toward the mounting base 4 when the locking claws 43A of the hooks 43 protrude from between the side edges 422 and 424 of the bearings 42. It is formed at a predetermined angle with respect to the surface of the other inner side edge portion 434 of each hook 43 so that it can be deformed and guided in an arc, and the hole 436 is formed on the side of the edge portion 433 of the other end of the hook 43 .

The coil springs 55 between the hooks 53 cause the locking claws 53A to protrude outward from between the left and right side edges 522 and 524 of the bearings 52 in a normal state.

そして、このヒンジ羽根2を他方の部材の取付プレートに取り付けるため、他方の部材の取付プレートに一対の軸受52が嵌装可能に取付孔が角形に、この場合、略長方形状の単純な形状に形成される。この場合、取付孔は長辺方向の寸法が各軸受52の外側(外向き)の面間の寸法と略同じかそれよりも僅かに大きく、短辺方向の寸法が各軸受52の両側縁部522、524の長辺方向の寸法と略同じかそれよりも僅かに大きく、全体として取付ベース5の平面の大きさより少し小さい開口として形成される。 In order to attach the hinge blade 2 to the mounting plate of the other member, the mounting hole is formed in a square shape, in this case, in a simple rectangular shape so that the pair of bearings 52 can be fitted in the mounting plate of the other member.

In this case, the pair of mounting holes B20 are formed in a rectangular shape (in this case, substantially rectangular) so that the pair of bearings 42 of the hinge body 1 can be fitted into the mounting plate B2. As shown in FIG. 10, the door D has hinge blades 2 attached to one side D1 on one side of the front. This side portion D1 corresponds to the mounting plate described above. Hereinafter, this side portion D1 will be referred to as a mounting plate D1. A pair of mounting holes D10 (only the upper mounting holes are shown in FIG. 10) are formed at predetermined positions on the upper and lower ends of the mounting plate D1. In this case, the pair of mounting holes D10 are formed in a rectangular shape (in this case, substantially rectangular) so that the hinge block 5A (pair of bearings 52) of the hinge blade 2 can be fitted into the mounting plate D1.

まず、図8に示すように、筐体Bの取付プレートB2の上下に、ヒンジ本体1を1つずつ取り付ける。なお、ヒンジ本体1は、使用前の通常の状態では、一対の軸受42の間で一対のフック43が各フック43間のコイルスプリング45(図2参照)により各軸受42の両側縁部422、424方向に押圧付勢されて、各フック43の外側一方の側縁部432から他端の縁部433の一部、すなわち、係止爪43Aが各軸受42の両側縁部422間、424間から外側に弾性的に突出され、取付ベース4の平面41で一対の軸受42間の両端部に凸段状に形成された各受け部412(図2参照)と各フック43の他端の縁部433の内側他方の側縁部434側の端部に形成された各ストッパー435との係合により、各フック43の各軸受42からの飛び出しが防止されている。
このヒンジ本体1を取付プレートB2の取付孔B20に取り付ける場合、ヒンジ本体1の取付ベース4の平面41に防水パッキン61を被着してから、ヒンジ本体1の各軸受42を縦向きにして取付プレートB2の取付孔B20の向きに合せ、各軸受42を各フック43とともに取付プレートB2の取付孔B20に差し込み、押し込む(ワンプッシュする)。
このようにすると、図9に示すように、ヒンジ本体1は各軸受42が、各軸受42の両側縁部422、424及び各外側(外向き)の平面が先端から中間へ、中間から基端へ取付プレートB2の取付孔B20の短辺方向及び長辺方向の各縁部を摺動しつつ、取付プレートB2の取付孔B20を通過する。この間、各軸受42の両側縁部422、424から外側に突出される各フック43の各係止爪43Aは取付プレートB2の取付孔B20の各短辺方向の縁部に接触して押圧され、各係止爪43Aが各フック43間のコイルスプリング45の付勢力に抗して(コイルスプリング45を圧縮しながら)各軸受42間に向けて回動し各軸受42の両側縁部422間内、424間内に没入されていく。そして(ヒンジ本体1が取付孔B20に押し込まれた瞬間)、各係止爪43Aが完全に各軸受42の両側縁部422間内、424間内に没入されて各軸受42が取付プレートB2の取付孔B20を完全に通過し、取付ベース1の平面41全周縁部のフランジ411が(防水パッキン61を介して)取付プレートB2の一方の面側で取付孔B20の全周縁部に当接するとともに、各軸受42内の各フック43は取付プレートB2の取付孔B20の通り抜けにより取付プレートB20の他方の面側で各フック43間のコイルスプリング45の付勢力(コイルスプリング45の弾性復帰)により各係止爪43Aが各軸受42間から各軸受42の両側縁部422、424方向に回動し各軸受42の両側縁部422間、424間から外側に突出されて、取付孔B20の各短辺方向の縁部に弾性係止される。ここで、このヒンジ本体1は、図3に示したように、各フック43の回動中心が各フック43の一端の縁部431側で外側一方の側縁部432寄りに設けられ、各フック43の他端の縁部433が円の中心を各フック43の回動中心よりも各フック43の一端の縁部431に近くかつ内側他方の側縁部434寄りの位置におく円弧状に形成されたことで、各フック43は、図9に示すように、各係止爪43Aの外側への回動とともに各係止爪43Aの円弧状の部分が取付孔B20の縁部に向けて迫り出して、取付孔B20の短辺方向の各縁部に食い込み、これにより、取付ベース4の平面41のフランジ411は(防水パッキン61を介して)取付プレートB2の一方の面側で取付孔B20の全周縁部に圧接されて、ヒンジ本体1が取付プレートB2に強固に取り付け固定される。このようにしてヒンジ本体1を筐体Bにワンタッチで確実に固定することができる。
First, as shown in FIG. 8, the hinge bodies 1 are attached to the top and bottom of the mounting plate B2 of the housing B one by one. In addition, in a normal state before use, the hinge body 1 is configured so that the pair of hooks 43 between the pair of bearings 42 are held by the coil springs 45 (see FIG. A portion of the outer one side edge 432 of each hook 43 to the other end edge 433, that is, the locking claw 43A is pushed in the 424 direction between the side edges 422 and 424 of each bearing 42. Each receiving portion 412 (see FIG. 2) elastically protruded outward from the mounting base 4 and formed in a convex step shape at both ends between the pair of bearings 42 on the plane 41 of the mounting base 4 and the edge of the other end of each hook 43 Each hook 43 is prevented from jumping out of each bearing 42 by engaging with each stopper 435 formed at the end of the portion 433 on the side of the inner side edge portion 434 .
When the hinge body 1 is attached to the mounting hole B20 of the mounting plate B2, the waterproof packing 61 is applied to the flat surface 41 of the mounting base 4 of the hinge body 1, and each bearing 42 of the hinge body 1 is vertically oriented. Matching the direction of the mounting hole B20 of the plate B2, each bearing 42 is inserted into the mounting hole B20 of the mounting plate B2 together with each hook 43 and pushed (one push).
In this way, as shown in FIG. 9, the hinge body 1 is such that each bearing 42 is so arranged that both side edges 422, 424 and each outer (outward) plane of each bearing 42 extend from distal to intermediate and intermediate to proximal. It passes through the mounting hole B20 of the mounting plate B2 while sliding on each edge in the short side direction and the long side direction of the mounting hole B20 of the mounting plate B2. During this time, the locking claws 43A of the hooks 43 projecting outward from the side edges 422 and 424 of the bearings 42 contact and are pressed against the short-side edges of the mounting holes B20 of the mounting plate B2, Each locking claw 43A rotates between the bearings 42 against the biasing force of the coil spring 45 between the hooks 43 (while compressing the coil spring 45), and rotates between the side edges 422 of each bearing 42. , 424 are immersed in the space. Then (at the moment when the hinge main body 1 is pushed into the mounting hole B20), the locking claws 43A are completely inserted between the side edges 422 and 424 of the bearings 42, and the bearings 42 are inserted into the mounting plate B2. It completely passes through the mounting hole B20, and the flange 411 on the entire periphery of the flat surface 41 of the mounting base 1 (via the waterproof packing 61) contacts the entire periphery of the mounting hole B20 on one side of the mounting plate B2 (via the waterproof packing 61). , each hook 43 in each bearing 42 is passed through the mounting hole B20 of the mounting plate B2, and the urging force of the coil spring 45 (elastic return of the coil spring 45) between the hooks 43 on the other side of the mounting plate B20 The locking claw 43A rotates from between the bearings 42 toward the side edges 422 and 424 of the bearings 42, protrudes outward from between the side edges 422 and 424 of the bearings 42, and engages the short sides of the mounting hole B20. It is elastically locked to the lateral edge. Here, as shown in FIG. 3, in this hinge body 1, the center of rotation of each hook 43 is provided near the edge 431 of one end of each hook 43 and near one side edge 432 of each hook. The edge 433 of the other end of 43 is formed in an arc shape with the center of the circle positioned closer to the edge 431 of one end of each hook 43 than the center of rotation of each hook 43 and closer to the other inner side edge 434 than the center of rotation of each hook 43. As a result, as shown in FIG. 9, each hook 43 rotates outwardly and the circular arc portion of each locking claw 43A presses toward the edge of the mounting hole B20. As a result, the flange 411 of the flat surface 41 of the mounting base 4 (through the waterproof packing 61) engages with the mounting hole B20 on one side of the mounting plate B2. The hinge main body 1 is firmly attached and fixed to the mounting plate B2. In this way, the hinge body 1 can be reliably fixed to the housing B with one touch.

次に、図10に示すように、扉Dの取付プレートD1の上下に、ヒンジ羽根2を1つずつ取り付ける。なお、ヒンジ羽根2は、使用前の通常の状態では、一対の軸受52の間で一対のフック53が各フック53間のコイルスプリング55(図5参照)により各軸受52の両側縁部522、524方向に押圧付勢されて、各フック53の外側一方の側縁部532から他端の縁部533の一部、すなわち、係止爪53Aが各軸受52の両側縁部522間、524間から外側に弾性的に突出され、一対の軸受52の突出端521側で一対のフック53の一端の周囲に当たる部分として、各軸受52間に表れる凸形状の内面で孔570の両側が取付ベース5の平面51と平行に形成された各受け部512(図5参照)と各フック53の一端の周面に各フック53の各係止爪53Aが各軸受52の両側縁部522間、524間から突出された状態で各軸受52間の各受け部512に係合可能に凸段状に形成されたストッパー535(図5参照)との係合により、各フック53の各軸受52から突出方向への過度の回動、すなわち各フック53の各軸受52からの飛び出しが規制されている。
このヒンジ羽根2を取付プレートD1の取付孔D10に取り付ける場合、ヒンジ羽根2の取付ベース5の平面51に防水パッキン62を被着してから、ヒンジ羽根2のヒンジブロック5Aを一対の軸受52を横向きにすることで取付プレートD1の取付孔D10に合せ、ヒンジブロック5Aを各フック53とともに取付プレートD1の取付孔D10に差し込み、押し込む(ワンプッシュする)。
このようにすると、図11に示すように、ヒンジ羽根2はヒンジブロック5Aが、各軸受52の両側縁部522、524及び各外側(外向き)の平面が先端から中間へ、中間から基端へ取付プレートD1の取付孔D10の短辺方向及び長辺方向の各縁部を摺動しつつ、取付プレートD1の取付孔D10を通過する。この間、各軸受52の両側縁部522間、524間から外側に突出される各フック53の各係止爪53Aは取付プレートD1の取付孔D10の各短辺方向の縁部に接触して押圧され、各係止爪53Aが各フック53間のコイルスプリング55(図5参照)の付勢力に抗して(コイルスプリング55を圧縮しながら)各軸受52間に向けて回動し各軸受52の両側縁部522間内、524間内に没入されていく。そして(ヒンジ羽根2が取付孔D10に押し込まれた瞬間)、各係止爪5Aが完全に各軸受52の両側縁部522間内、524間内に没入されて各軸受52が取付プレートD1の取付孔D10を完全に通過し、取付ベース5は平面51全周縁部のフランジ511が(防水パッキン62を介して)取付プレートD1の一方の面側で取付孔D10の全周縁部に当接するとともに、各軸受52内の各フック53は取付プレートD1の取付孔D10の通り抜けにより取付プレートD1の他方の面側で各フック53間のコイルスプリング55(図5参照)の付勢力(コイルスプリング55の弾性復帰)により各係止爪53Aが各軸受52間から各軸受52の両側縁部522、524方向に回動し各軸受52の両側縁部522間、524間から外側に突出されて、取付孔D10の各短辺方向の縁部に弾性係止される。ここで、このヒンジ羽根2は、図6に示したように、各フック53の回動中心が各フック53の一端の縁部531側に設けられ、各フック53の他端の縁部533は円の中心を各フック53の回動中心よりも各フック53の一端の縁部531に近くかつ内側他方の側縁部534寄りの位置におく円弧状に形成されることで、各フック53は、図11に示すように、各係止爪53Aの外側への回動とともに各係止爪53Aの円弧状の部分が取付孔D10の縁部に向けて迫り出して、取付孔D10の短辺方向の各縁部に食い込み、これにより、取付ベース5の平面51のフランジ511は(防水パッキン62を介して)取付プレートD1の一方の面側で取付孔D10の全周縁部に圧接されて、ヒンジ羽根2が取付プレートD1に強固に取り付け固定される。このようにしてヒンジ羽根2を扉Dにワンタッチで確実に固定することができる。また、このヒンジ羽根2にあっては、一対のフック53のヒンジ本体1の各フック43とは異なる形状により、各フック53、各軸受52を共にヒンジ本体1の各フック43、各軸受42よりも小型化することができ、扉の側部で角部に近い箇所にも簡易に取り付けることができる。
Next, as shown in FIG. 10, the hinge blades 2 are attached to the top and bottom of the mounting plate D1 of the door D one by one. In addition, in the normal state before use, the hinge blade 2 is configured so that the pair of hooks 53 between the pair of bearings 52 are held by the coil springs 55 (see FIG. A portion of the outer side edge 532 to the other edge 533 of each hook 53 , that is, the locking claw 53</b>A is pushed in the direction 524 between the side edges 522 and 524 of each bearing 52 . Both sides of the hole 570 on the convex inner surface appearing between the bearings 52 as a portion that elastically protrudes outward from the pair of bearings 52 and contacts the circumference of one end of the pair of hooks 53 on the protruding end 521 side of the pair of bearings 52 . Each receiving portion 512 (see FIG. 5) formed parallel to the plane 51 of the bearing 52 and each locking pawl 53A of each hook 53 on the peripheral surface of one end of each hook 53 is between both side edges 522 and 524 of each bearing 52. By engaging with a stopper 535 (see FIG. 5) that is formed in a convex step shape to be able to engage with each receiving portion 512 between each bearing 52 while protruding from each bearing 52, each hook 53 protrudes from each bearing 52 Excessive turning to the right, that is, projection of each hook 53 from each bearing 52 is restricted.
When the hinge blade 2 is attached to the mounting hole D10 of the mounting plate D1, the waterproof packing 62 is applied to the flat surface 51 of the mounting base 5 of the hinge blade 2, and then the hinge block 5A of the hinge blade 2 is attached to the pair of bearings 52. By turning it sideways, it is aligned with the mounting hole D10 of the mounting plate D1, and the hinge block 5A is inserted into the mounting hole D10 of the mounting plate D1 together with each hook 53 and pushed (one push).
In this way, as shown in FIG. 11, the hinge vanes 2 are arranged such that the hinge blocks 5A are aligned so that both side edges 522, 524 of each bearing 52 and each outer (outward) plane extend from distal to intermediate and intermediate to proximal. It passes through the mounting hole D10 of the mounting plate D1 while sliding along the edges in the short side direction and the long side direction of the mounting hole D10 of the mounting plate D1. During this time, the locking claws 53A of the hooks 53 protruding outward from between the side edges 522 and 524 of the bearings 52 contact and press against the short-side edges of the mounting holes D10 of the mounting plate D1. Then, each locking pawl 53A rotates toward between the bearings 52 against the biasing force of the coil spring 55 (see FIG. 5) between the hooks 53 (while compressing the coil spring 55). It is immersed in between the both side edges 522 and 524 of the. Then (at the moment when the hinge blade 2 is pushed into the mounting hole D10), the locking claws 5A are completely inserted between the side edges 522 and 524 of the bearings 52, and the bearings 52 are attached to the mounting plate D1. The mounting base 5 completely passes through the mounting hole D10, and the flange 511 on the entire periphery of the plane 51 of the mounting base 5 abuts the entire periphery of the mounting hole D10 on one side of the mounting plate D1 (via the waterproof packing 62). , each hook 53 in each bearing 52 passes through the mounting hole D10 of the mounting plate D1, the biasing force of the coil spring 55 (see FIG. 5) between the hooks 53 on the other side of the mounting plate D1 Each locking claw 53A rotates from between the bearings 52 in the direction of the side edges 522 and 524 of the bearings 52 due to the elastic return), and protrudes outward from between the side edges 522 and 524 of the bearings 52, and is attached. It is elastically locked to each short-side edge of the hole D10. Here, in this hinge blade 2, as shown in FIG. Each hook 53 is formed in an arc shape in which the center of the circle is positioned closer to the edge 531 at one end of each hook 53 than the center of rotation of each hook 53 and closer to the other inner side edge 534 . As shown in FIG. 11, as each locking claw 53A rotates outward, the arc-shaped portion of each locking claw 53A protrudes toward the edge of the mounting hole D10, and the short side of the mounting hole D10 is pushed out. By this, the flange 511 of the flat surface 51 of the mounting base 5 (via the waterproof packing 62) is pressed against the entire peripheral edge of the mounting hole D10 on one side of the mounting plate D1, The hinge blade 2 is firmly attached and fixed to the attachment plate D1. In this way, the hinge blade 2 can be reliably fixed to the door D with one touch. In addition, in this hinge blade 2, the hooks 53 of the pair of hooks 53 have a different shape from the hooks 43 of the hinge body 1, so that the hooks 53 and the bearings 52 are both attached to the hooks 43 and the bearings 42 of the hinge body 1. can also be made smaller, and can be easily attached to a portion near the corner on the side of the door.

そして、図12に示すように、筐体Bのヒンジ本体1と扉Dのヒンジ羽根2とをヒンジピン3を介して連結し、筐体Bに扉Dを取り付ける。
この場合、まず、ヒンジ本体1の上下の各ヒンジピン挿通部47にヒンジピン3をなす各ピン3A、3Bを挿入し、各ピン3A、3Bの先端側所定の位置の係止溝31(図7参照)と上下の各ヒンジピン挿通部47内のヒンジピンストッパー491dとを係合させて、各ピン3A、3Bを上下の各ヒンジピン挿通部47内に保持してヒンジピン3を待機させる。続いて、筐体B側のヒンジ本体1の上下のヒンジピン挿通部47間の間欠部48に扉D側のヒンジ羽根2のヒンジブロック5Aのヒンジピン挿通部57側の略半部を嵌め込み、相互のヒンジピン挿通部47、57を連通させる。そして、この状態からヒンジ本体1の上下の各ヒンジピン挿通部47内に保持され待機中の各ピン3A、3Bを押し込んで、各ピン3A、3Bの先端側所定の位置の係止溝31(図7参照)と上下の各ヒンジピン挿通部47内のヒンジピンストッパー491dとの係合を係止ガイド311(図7参照)により解除し、各ピン3A、3Bの外周面でヒンジピンストッパー491dを押し退けながら各ピン3A、3Bをヒンジ本体1の上下の各ヒンジピン挿通部47からヒンジ羽根2のヒンジピン挿通部57(の略半分)まで挿通させると、各ピン3A、3Bの外周面の中間部所定の位置の係止溝32(図7参照)に係止ガイド321(図7参照)の案内によりヒンジピンストッパー491dが係止され、各ピン3A、3Bが軸方向の動きを規制されて固定される。このようにしてヒンジ本体1とヒンジ羽根2がヒンジピン3により連結され、筐体Bに扉Dが回動可能に取り付けられる。
Then, as shown in FIG. 12, the hinge main body 1 of the housing B and the hinge blade 2 of the door D are connected via the hinge pin 3, and the door D is attached to the housing B. As shown in FIG.
In this case, first, the pins 3A and 3B forming the hinge pin 3 are inserted into the upper and lower hinge pin insertion portions 47 of the hinge body 1, and the locking grooves 31 (see FIG. 7) at predetermined positions on the distal end sides of the pins 3A and 3B are inserted. ) and the hinge pin stoppers 491d in the upper and lower hinge pin insertion portions 47 are engaged to hold the pins 3A and 3B in the upper and lower hinge pin insertion portions 47, and the hinge pin 3 is made to stand by. Subsequently, approximately half of the hinge block 5A of the hinge block 5A of the door D side is fitted into the intermittent portion 48 between the upper and lower hinge pin insertion portions 47 of the hinge main body 1 of the housing B side, and the mutual The hinge pin insertion portions 47 and 57 are communicated. Then, from this state, the pins 3A and 3B which are held in the upper and lower hinge pin insertion portions 47 of the hinge body 1 and are waiting are pushed in, and the locking grooves 31 (Fig. 7) and the hinge pin stoppers 491d in the upper and lower hinge pin insertion portions 47 are released by the locking guides 311 (see FIG. 7), and the hinge pin stoppers 491d are pushed aside by the outer peripheral surfaces of the pins 3A and 3B. When the pins 3A and 3B are inserted from the upper and lower hinge pin insertion portions 47 of the hinge main body 1 to (substantially half of) the hinge pin insertion portions 57 of the hinge blade 2, intermediate portions of the outer peripheral surfaces of the pins 3A and 3B are positioned at predetermined positions. The hinge pin stopper 491d is locked in the locking groove 32 (see FIG. 7) by the guidance of the locking guide 321 (see FIG. 7), and the pins 3A and 3B are fixed with their axial movement restricted. In this way, the hinge main body 1 and the hinge blade 2 are connected by the hinge pin 3, and the door D is attached to the housing B so as to be rotatable.

以上説明したように、このワンタッチ取付ヒンジHによれば、既述の構成により、筐体と扉など2部材の取付プレートにヒンジ本体1、ヒンジ羽根2の各軸受42、52を嵌装可能な取付孔を形成されて、ヒンジ本体1、ヒンジ羽根2がそれぞれ、各軸受42、52が各係止爪43A、53Aとともに取付プレートの取付孔に取付プレートの一方の面側から他方の面側に向けてワンプッシュで通され、一方の面側で取付ベース4、5のフランジ411、511が取付孔の縁部に圧接されるとともに、他方の面側で各フック43、53の各係止爪43A、53Aが取付孔の縁部に係止されて、各部材の取付プレートに取り付けられるので、筐体と扉など2部材にヒンジ部品(ヒンジ本体1、ヒンジ羽根2)を溶接や取付ねじを用いることなしにワンタッチで簡易に取り付けることができ、また、溶接や取付ねじを用いないことで、ヒンジHの取り付けに要する部品点数を大幅に削減し、コストの大幅な低減を図ることができる。 As described above, according to the one-touch mounting hinge H, the bearings 42 and 52 of the hinge main body 1 and the hinge blade 2 can be fitted to the two-member mounting plate such as the housing and the door due to the structure described above. Mounting holes are formed so that the hinge body 1 and the hinge blades 2, the bearings 42 and 52, together with the locking claws 43A and 53A, are inserted into the mounting holes of the mounting plate from one surface side to the other surface side of the mounting plate. The flanges 411 and 511 of the mounting bases 4 and 5 are pressed against the edges of the mounting holes on one side and the locking claws of the hooks 43 and 53 on the other side. 43A and 53A are locked to the edge of the mounting hole and attached to the mounting plate of each member. The number of parts required for mounting the hinge H can be greatly reduced by not using welding or mounting screws, and the cost can be greatly reduced.

また、このヒンジHはさらに次のような利点を有する。
(1)このヒンジ本体1では、一対のフック43はそれぞれ、一端の縁部431側で外側一方の側縁部432寄りに回動中心として軸挿通部430が設けられ、他端側の縁部433が円の中心を回動中心よりも一端の縁部431に近くかつ内側他方の側縁部434寄りの位置におく円弧状に形成されることで、このヒンジ本体1を取付プレートの取付孔に通しワンプッシュした後の各フック43を、各係止爪43Aの外側への回動とともにこの係止爪43Aの円弧状の部分が取付孔の縁部に向けて迫り出して、取付孔の縁部に食い付かせることができ、これにより、取付ベース4の平面41のフランジ411を取付プレートの取付孔の全周縁部に圧接させ、取付プレートを取付ベース4と一対のフック43との間で締め付けて、ヒンジ本体1を取付プレートに確実に固定することができる。
(2)このヒンジ本体1では、一対のフック43はそれぞれ、外側一方の側縁部432が各軸受42の各側縁部422、424と平行に形成され、一端の縁部431で、外側一方の側縁部432側の一部が円の中心を回動中心におく円弧状に形成され、内側他方の側縁部434側の残部が回動中心を対称中心として外側一方の側縁部432と対称的に斜めに形成され、内側他方の側縁部434が外側一方の側縁部432と平行に又は平行よりも少し開く方向に向けて形成されることで、各フック43を角形の一対の軸受42内に各係止爪43Aのみが各軸受42の両側縁部422間、424間から出没可能に配置することができる。

Further, this hinge H has the following advantages.
(1) In this hinge main body 1, each of the pair of hooks 43 is provided with a shaft insertion portion 430 as a rotation center on the edge portion 431 side of one end and near one side edge portion 432 of the outer side, and the edge portion on the other end side. 433 is formed in an arc shape with the center of the circle positioned closer to the edge 431 at one end and closer to the side edge 434 at the other inner side than the center of rotation, so that the hinge body 1 can be attached to the mounting hole of the mounting plate. After each hook 43 has been pushed through the hole, the arc-shaped portion of the locking claw 43A protrudes toward the edge of the mounting hole as the locking claw 43A rotates outward. The edge can be bitten, so that the flange 411 of the flat surface 41 of the mounting base 4 is pressed against the entire peripheral edge of the mounting hole of the mounting plate, and the mounting plate is between the mounting base 4 and the pair of hooks 43. can be tightened to securely fix the hinge body 1 to the mounting plate.
(2) In this hinge body 1, each of the pair of hooks 43 has an outer one side edge 432 formed in parallel with each of the side edges 422 and 424 of each bearing 42, and the one end edge 431 A part on the side edge 432 side of is formed in an arc shape with the center of the circle as the center of rotation, and the remaining part on the side of the other inner side edge 434 is symmetrical about the center of rotation. , and the other inner side edge 434 is formed parallel to the outer one side edge 432 or in a direction that opens a little more than parallel, so that each hook 43 is formed into a pair of squares. Only the locking claws 43A can be arranged in the bearings 42 so as to protrude from between the side edges 422 and 424 of the bearings 42, respectively.
In this case, receiving portions 412 are formed at both ends between the pair of bearings 42 on the flat surface 41 of the mounting base 4 , and at the edge 433 of the other end of each hook 43 on the other inner side edge 434 side. Each stopper 435 is formed, and the engagement between each receiving portion 412 of the mounting base 4 and each stopper 435 of each hook 43 restricts excessive rotation of each hook 43 in the projecting direction from each bearing 42. Therefore, it is possible to reliably prevent the hooks 43 from jumping out of the bearings 42, and the locking claws 43A of the hooks 43 can be reliably projected and retracted from between the side edges 422 and 424 of the bearings 42. .
Also, in this case, a cylindrical hole 436 is formed in the other inner side edge portion 434 of the pair of hooks 43 , and a coil spring 45 is employed as a spring member. Since the hooks 43 are held between the hooks 43, the hooks 43 can be reliably rotated in the directions of the side edges 422, 424 of the bearings 42 with a simple structure.
Furthermore, in this case, each hole 436 of the pair of hooks 43 is formed before or after the pair of bearings 42 are passed through the mounting holes of the mounting plate together with each hook 43, and each locking claw 43A of each hook 43 is inserted into each bearing. 42, the coil spring 45 can be deformed and guided in a convex circular arc shape toward the mounting base 4 side, relative to the other inner side edge portion 434 of each hook 43. A portion 437 of the inner peripheral surface of each hole 436 on the edge 433 side of the other end of each hook 43 is formed at a predetermined angle so that the pair of bearings 42 together with each hook 43 are inserted into the mounting hole of the mounting plate. When the locking claws 43A of the hooks 43 are inserted between the side edges 422 and 424 of the bearings 42 while the coil springs 45 are being passed through, the coil springs 45 are formed in an arcuate shape convex to the side opposite to the mounting base 4. Since the hole 436 is inclined at a predetermined angle so that the diameter is gradually increased from the inner side of the hole 436 toward the opening side, the elastic deformation of the coil spring 45 is improved. The locking claws 43A can be reliably and smoothly protruded and retracted from between the side edges 422 and 424 of each bearing 42 .
(3) In the hinge blade 2, each of the pair of hooks 53 is provided with a shaft insertion portion 530 on the side of the edge portion 531 at one end as the center of rotation, and the edge portion 533 on the other end side of the pair of hooks 53 has the center of the circle from the center of rotation. is formed in an arc shape near the edge 531 of one end and near the side edge 534 of the other inside, each hook 53 after the hinge blade 2 is passed through the mounting hole of the mounting plate and one push is performed. As each locking claw 53A rotates outward, the arc-shaped portion of the locking claw 53A protrudes toward the edge of the mounting hole and bites into the edge of the mounting hole. As a result, the flange 511 of the flat surface 51 of the mounting base 5 is brought into pressure contact with the entire periphery of the mounting hole of the mounting plate, the mounting plate is clamped between the mounting base 5 and the pair of hooks 53, and the hinge blade 2 is attached. It can be securely fixed to the mounting plate.
(4) In the hinge blade 2, each of the pair of hooks 53 has one outer side edge 532 formed in parallel with each side edge 522, 524 of each bearing 52, and one end edge 531 aligning with the center of the circle. It is formed in an arc shape centered on the center of rotation, and the other inner side edge portion 534 is formed symmetrically with the one outer side edge portion 532 in a direction that opens slightly from being parallel to the one outer side edge portion 532 . Thus, each hook 53 can be arranged in a pair of rectangular bearings 52 so that only each locking claw 53A can protrude from between both side edges 522 and 524 of each bearing 52 .
In this case, a receiving portion 512 is formed around one end of the pair of hooks 53 on the protruding end 521 side of the pair of bearings 52 , and a stopper 535 is formed on the peripheral surface of one end of each hook 53 . The engagement between the receiving portions 512 and the stoppers 535 of the hooks 53 restricts excessive rotation of the hooks 53 in the projecting direction from the bearings 52 . can be reliably prevented from popping out, and the locking claws 53A of the hooks 53 can be reliably projected and retracted from between the side edges 522 and 524 of the bearings 52. As shown in FIG.
Also, in this case, a cylindrical hole 536 is formed in the other inner side edge portion 534 of the pair of hooks 53 , and a coil spring 55 is employed as a spring member. Since the hooks 53 are held between the hooks 53, the hooks 53 can be reliably rotated in the directions of the side edges 522 and 524 of the bearings 52 with a simple structure.
Furthermore, in this case, each hole 536 of the pair of hooks 53 is arranged before or after the pair of bearings 52 are passed through the mounting holes of the mounting plate together with each hook 53, and each locking claw 53A of each hook 53 is inserted into each bearing. 52, the coil spring 55 can be deformed and guided in a convex circular arc shape toward the mounting base 5 side. A portion 537 of the inner peripheral surface of each hole 536 on the edge 531 side of one end of each hook 53 is formed at a predetermined angle so that the pair of bearings 52 and each hook 53 pass through the mounting hole of the mounting plate. When the locking claws 53A of the hooks 53 are inserted between the side edges 522 and 524 of the bearings 52, the coil springs 55 are formed in a convex arc on the side opposite to the mounting base 5. Since the hole 536 is inclined at a predetermined angle so that the diameter of the hole 536 is gradually increased from the inner side toward the opening side so that the deformation can be guided, the expansion and contraction deformation of the coil spring 55 is improved, and each hook of each hook 53 is inclined. The locking claws 53A can be reliably and smoothly projected and retracted from between the side edges 522 and 524 of the bearings 52 .

A coil spring 45 interposed between the hooks 43 causes the locking claw 43A to protrude outward from between the upper and lower side edges 422 and 424 of the bearings 42 in a normal state. In addition, the tip side of the inner surface portion 434 of each hook 43 and each receiving portion 412 of the hinge body mounting base 4 can be engaged with each other. Excessive rotation, that is, projection of each hook 43 from each bearing 42 is restricted.

そして、ヒンジ本体1を一方の部材のヒンジ本体側の取付部に取り付けるため、一方の部材のヒンジ本体側の取付部に一対の軸受42が嵌装可能に取付孔が角形に、この場合、略長方形状の単純な形状に形成される。この場合、取付孔は長辺方向の寸法が各軸受42の長辺方向の寸法と略同じかそれよりも僅かに大きく、短辺方向の寸法が各軸受42の外側(外向き)の面間の寸法と略同じかそれよりも僅かに大きく、全体としてヒンジ本体取付ベース4の平面の大きさより少し小さい開口として形成される。 In order to attach the hinge body 1 to the hinge body side attachment portion of the one member, the attachment hole is made rectangular so that the pair of bearings 42 can be fitted to the hinge body side attachment portion of the one member. It is formed in a simple rectangular shape. In this case, the mounting hole has a long side dimension that is approximately the same as or slightly larger than the long side dimension of each bearing 42 , and a short side dimension that is between the outer (outward) surfaces of each bearing 42 . , and is formed as an opening that is slightly smaller than the size of the plane of the hinge body mounting base 4 as a whole.

かくしてヒンジ本体1は、ヒンジ本体側の一対の軸受42が各係止爪43Aとともにヒンジ本体側の取付部の取付孔に当該取付部の一方の面側から他方の面側に向けてワンプッシュで通されて、一方の面側でヒンジ本体取付ベース4のフランジ411がヒンジ本体側の取付孔の縁部周囲に圧接されるとともに、他方の面側でヒンジ本体側の各フック43の各係止爪43Aがヒンジ本体側の取付孔の縁部又は縁部周囲に係止されて、ヒンジ本体側の取付部に取り付けられる。 Thus, in the hinge body 1, the pair of bearings 42 on the hinge body side together with the locking pawls 43A can be pushed into the mounting holes of the mounting portion on the hinge body side with one push from one side of the mounting portion toward the other side. As a result, the flange 411 of the hinge body mounting base 4 is pressed against the periphery of the mounting hole on the hinge body side on one side, and the hooks 43 on the hinge body side are engaged on the other side. The claw 43A is engaged with the edge of the attachment hole on the hinge body side or around the edge, and attached to the attachment portion on the hinge body side.

As shown in FIG. 18, the center of rotation of the hook 53 is provided on the edge 531 side of one end of the hook 53 corresponding to one end side of each bearing 52 on both sides opposed to (the inner surface of) each bearing 52 . A shaft insertion portion 530 is provided here so that the shaft 54 can be inserted therethrough. It is formed in an arc shape at a position closer to the edge 531 at one end of the hook 53 than the center of rotation and closer to the inner surface portion 534 opposite to the outer surface portion 532 .

また、このフック53は、図18に示すように、外面部532が一対の軸受52の各突出端521と略平行に形成される。一方の縁部531、つまり、外面部532の一端と内面部534の一端との間が断面略V字形の突状に形成されて外面部532に連続する一方の面が所定の円弧状の面に、内面部534に連続する他方の面は所定の角度を付けた傾斜面に形成される。なお、この内面部534に連続する他方の面は外面部532に連続する一方の面との間に所定の角度を付けられて、ヒンジ羽根側の一対の軸受52の底部に係合可能なストッパー535になって、このストッパー535と各軸受52の底部との衝接係合により、フック53の各軸受52間から突出方向への過度の回動、すなわちフック53の各軸受52からの飛び出し(図14参照)が規制されるようになっている。そして、内面部534が外面部532と対称的に外面部532と平行に又は平行よりも少し開く方向に向けて、この場合は、平行よりも少し開く方向に向けて形成される。なお、ここでフック53の外面部532、内面部534は四角形の平面に、左右の各側面部53Sは外面部532、内面部534の幅よりも幅狭の四角形の平面に、そして、既述のとおり、一方の縁部531が断面略V字形で、この場合、外面部532に連続する一方の面は所定の円弧状の面に、内面部534に連続する他方の面は所定の角度を付けた傾斜面(ストッパー535)に、他方の縁部533が外面部532、内面部534の幅よりも幅狭の四角形で断面円弧状の面になっている。 Also, as shown in FIG. 18, the hook 53 has an outer surface portion 532 that is substantially parallel to the projecting ends 521 of the pair of bearings 52 . One edge portion 531, that is, between one end of the outer surface portion 532 and one end of the inner surface portion 534 is formed in a protruded shape having a substantially V-shaped cross section, and one surface continuous with the outer surface portion 532 is a predetermined arcuate surface. In addition, the other surface continuous with the inner surface portion 534 is formed as an inclined surface with a predetermined angle. The other surface that is continuous with the inner surface portion 534 is formed at a predetermined angle with the one surface that is continuous with the outer surface portion 532, and is a stopper that can be engaged with the bottoms of the pair of bearings 52 on the hinge blade side. At 535, the contact engagement between the stopper 535 and the bottom of each bearing 52 causes the hook 53 to rotate excessively in the projecting direction from between the bearings 52, that is, the hook 53 protrudes from each bearing 52 ( 14) is regulated. Then, the inner surface portion 534 is formed symmetrically with the outer surface portion 532 in parallel with the outer surface portion 532 or in a direction that is slightly wider than parallel, in this case, in a direction that is slightly wider than parallel. Here, the outer surface portion 532 and the inner surface portion 534 of the hook 53 are square planes, the left and right side surface portions 53S are square planes narrower than the width of the outer surface portion 532 and the inner surface portion 534, and the above-described , one edge portion 531 has a substantially V-shaped cross section, in which case one surface continuous with the outer surface portion 532 forms a predetermined arcuate surface, and the other surface continuous with the inner surface portion 534 forms a predetermined angle. On the inclined surface (stopper 535) attached, the other edge 533 is a rectangular surface narrower than the width of the outer surface portion 532 and the inner surface portion 534 and has an arcuate cross section.

ばね部材55はコイルスプリングが採用される(以下、コイルスプリング55という。)。この場合、図18に示すように、フック53の内面部534に円筒状の孔536が形成され、コイルスプリング55は一端をフック53の孔536に保持され、他端をヒンジ羽根側の一対の軸受52間の底部に保持されて、フック53と各軸受52間の底部との間に介装される。また、この場合、各フック53の孔536は、このヒンジ羽根2が他方の部材のヒンジ羽根側の取付部の取付孔に取り付けられる際に一対の軸受52がフック53とともにヒンジ羽根側の取付部の取付孔に通される前又は後でフック53の各係止爪53Aが各軸受52の各突出端521間から突出されたときにコイルスプリング55をヒンジ羽根取付ベース5の他方のプレート512a側に凸の円弧状に変形案内可能に、フック53の内面部534の面に対して所定の角度を付けて形成され、、かつ孔536の各フック53の他端の縁部側又は一端の縁部側の内周面の一部が、一対の軸受52が各フック53とともにヒンジ本体側の取付部の取付孔に通される間で、各フック53の係止爪53Aが各軸受52の各突出端521間に没入されたときに、コイルスプリング55をヒンジ羽根取付ベース5の他方のプレート512aとは反対側に凸の円弧状に変形案内可能に、孔536の奥側から開口側に向けて漸次拡径される所定の角度の傾斜を付けて形成される。 A coil spring is employed as the spring member 55 (hereinafter referred to as a coil spring 55).

FIGS. 19 to 24 show examples of the use of the one-touch mounting hinge H2 in the case of mounting a door to a rack housing with the hinge H2.
In addition, as shown in FIGS. 19 and 21, the rack consists of a housing B and a door D. As shown in FIG. As shown in FIG. 19, the housing B is provided with a fixed frame B1 around the front opening, and the hinge body 1 is attached to one side plate B2 of the fixed frame B1. This side plate B2 corresponds to the mounting portion on the side of the hinge main body described above. Hereinafter, this side plate B2 will be referred to as a mounting portion B2 on the side of the hinge body. Mounting holes B20 (only the mounting hole B20 at the upper end is shown in FIG. 19) are formed at predetermined positions on both upper and lower ends of the mounting portion B2 on the side of the hinge body. In this case, these mounting holes B20 are formed in a rectangular shape (in this case, substantially rectangular) so that the pair of bearings 42 of the hinge body 1 can be fitted into the mounting portion B2 on the hinge body side. As shown in FIG. 21, the door D is composed of a square front plate and four side plates, and a hinge blade 2 is attached across the two surfaces at a corner portion D1 between the front plate d1 and the left side plate d2. be done. This corner portion D1 corresponds to the attachment portion on the side of the hinge blade described above. Hereinafter, this corner portion D1 is referred to as a hinge blade side mounting portion D1. Mounting holes D10 (only the mounting hole D10 at the upper end is shown in FIG. 21) are formed at predetermined positions on both upper and lower ends of the mounting portion D1 on the hinge blade side. In this case, these mounting holes D10 are rectangular (in this case, substantially rectangular) so that the pair of bearings 52 on the hinge blade side can be fitted to the front plate d1 (surface in the other direction) at the mounting portion D1 on the hinge blade side. Openings D101 (openings on the other side) are formed in the left side plate d2 (on the side in one direction), communicating with the openings D101 on the side of the front plate d1 and engaging with the grooves 56 of the block 5A of the hinge blade 2. An opening D102 having a rectangular shape (in this case, a substantially rectangular shape) having two locking edges D103 that can be combined and having a lower height than the opening D101 on the front plate d1 side by the amount of the locking edge D103 is formed. are formed as two continuous openings D101 and D102 across the two surfaces.

まず、図19に示すように、筐体Bのヒンジ本体側の取付部B2の上下に、ヒンジ本体1を1つずつ取り付ける。なお、ヒンジ本体1は、使用前の通常の状態では、一対の軸受42の間で一対のフック43が各フック43間のコイルスプリング45(図20参照)により各軸受42の一方の両側縁部422、他方の両側縁部424方向に押圧付勢されて、各フック43の外面部432から他端の縁部433にかけて、すなわち、係止爪43Aが各軸受42の一方の両側縁部422間、他方の両側縁部424間から外側に弾性的に突出される。なお、この状態は、各フック43の内面部434の先端側の一部とヒンジ本体取付ベース4の各受け部412との係合により各フック43の各軸受42からの飛び出しが防止されて(図20参照)、保持される。このヒンジ本体1をヒンジ本体側の取付部B2の取付孔B20に取り付ける場合、ヒンジ本体1のヒンジ本体取付ベース4の平面41に防水パッキン61を被着してから、ヒンジ本体1の各軸受42を縦向きにして取付プレートB2の取付孔B20の向きに合せ、各軸受42を各フック43とともに取付プレートB2の取付孔B20に差し込み、押し込む(ワンプッシュする)。
このようにすると、図19、図20に示すように、ヒンジ本体1は各軸受42が、各軸受42の一方の両側縁部422、他方の両側縁部424及び各外側(外向き)の平面が先端から中間へ、中間から基端へヒンジ本体側の取付部B2の取付孔B20の短辺方向及び長辺方向の各縁部を摺動しつつ、ヒンジ本体側の取付部B2の取付孔B20を通過する。この間、各軸受42の一方の両側縁部422、他方の両側縁部424から外側に突出される各フック43の各係止爪43Aは取付プレートB2の取付孔B20の各短辺方向の縁部に接触して押圧され、各係止爪43Aが各フック43間のコイルスプリング45の付勢力に抗して(コイルスプリング45を圧縮しながら)各軸受42間に向けて回動し各軸受42の一方の両側縁部422間内、他方の両側縁部424間内に没入されていく。そして(ヒンジ本体1が取付孔B20に押し込まれた瞬間)、各係止爪43Aが完全に各軸受42の各両側縁部422間内、424間内に没入されて各軸受42がヒンジ本体側の取付部B2の取付孔B20を完全に通過し、ヒンジ本体取付ベース4の平面41全周縁部のフランジ411が(防水パッキン61を介して)ヒンジ本体側の取付部B2の一方の面側で取付孔B20の全周縁部に当接するとともに、各軸受42内の各フック43はヒンジ本体側の取付部B2の取付孔B20の通り抜けによりヒンジ本体側の取付部B20の他方の面側で各フック43間のコイルスプリング45の付勢力(コイルスプリング45の弾性復帰)により各係止爪43Aが各軸受42間から各軸受42の両側縁部422、424方向に回動し各軸受42の各両側縁部422間、424間から外側に突出されて、取付孔B20の各短辺方向の縁部に弾性係止される。ここで、このヒンジ本体1は、図15に示したように、各フック43の回動中心が各フック43の一端の縁部431側に設けられ、各フック43の他端の縁部433が円の中心を各フック43の回動中心よりも各フック43の一端の縁部431に近くかつ内面部434寄りの位置におく円弧状に形成されたことで、各フック43は、図19に示すように、各係止爪43Aの外側への回動とともに各係止爪43Aの円弧状の部分が取付孔B20の縁部に向けて迫り出して、取付孔B20の短辺方向の各縁部に食い込み、これにより、取付ベース4の平面41のフランジ411は(防水パッキン61を介して)ヒンジ本体側の取付部B2の一方の面側で取付孔B20の全周縁部に圧接されて、ヒンジ本体1がヒンジ本体側の取付部B2に強固に取り付け固定される。このようにしてヒンジ本体1を筐体Bにワンタッチで確実に固定することができる。図24にこのヒンジ本体1を異なる厚さの2種類の取付プレートに適用した場合を示している。このヒンジ本体1のフック43特有の係止爪43Aの形状、特に他端の縁部433の円弧形状により、取付プレートの厚さが異なる場合でも、各係止爪43Aの円弧状の部分を取付孔B20の縁部に向けて迫り出して確実に食い込ませることができる。
First, as shown in FIG. 19, the hinge main bodies 1 are attached one by one above and below the attachment portion B2 on the hinge main body side of the housing B. As shown in FIG. In addition, in the normal state before use, the hinge body 1 is configured such that the pair of hooks 43 are held between the pair of bearings 42 by the coil springs 45 (see FIG. 20) between the hooks 43 on one side edge of each bearing 42 . 422 , is pressed and biased in the direction of the other side edge 424 of each hook 43 from the outer surface portion 432 to the other edge 433 of each hook 43 , that is, the locking claw 43A is between the one side edge 422 of each bearing 42 . , elastically protrudes outward from between the other side edges 424 . In this state, each hook 43 is prevented from jumping out of each bearing 42 by engagement between a portion of the tip side of the inner surface portion 434 of each hook 43 and each receiving portion 412 of the hinge body mounting base 4 ( 20) and is retained. When attaching the hinge body 1 to the attachment hole B20 of the attachment portion B2 on the hinge body side, the waterproof packing 61 is applied to the flat surface 41 of the hinge body attachment base 4 of the hinge body 1, and then each bearing 42 of the hinge body 1 is fitted. is aligned with the mounting hole B20 of the mounting plate B2, and each bearing 42 is inserted into the mounting hole B20 of the mounting plate B2 together with each hook 43 and pushed (one push).
In this way, as shown in FIGS. 19 and 20, the hinge body 1 is such that each bearing 42 is formed by one side edge 422 of each bearing 42, the other side edge 424 of each bearing 42, and each outer (outward) plane. While sliding from the tip to the middle and from the middle to the base end along each of the edges in the short side direction and the long side direction of the mounting hole B20 of the mounting portion B2 on the hinge body side, the mounting hole of the mounting portion B2 on the hinge body side Pass B20. During this time, the locking claws 43A of the hooks 43 projecting outward from one side edge 422 and the other side edge 424 of each bearing 42 are aligned with the short side edges of the mounting hole B20 of the mounting plate B2. , each locking claw 43A rotates toward between the bearings 42 against the biasing force of the coil spring 45 between the hooks 43 (while compressing the coil spring 45). It is immersed in between one side edge 422 and between the other side edge 424 . Then (at the moment when the hinge body 1 is pushed into the mounting hole B20), the locking claws 43A are completely retracted between the side edges 422 and 424 of the bearings 42, and the bearings 42 move toward the hinge body. completely through the mounting hole B20 of the mounting portion B2 of the hinge body mounting base 4, and the flange 411 of the entire periphery of the flat surface 41 of the hinge body mounting base 4 (via the waterproof packing 61) is on one side of the mounting portion B2 on the hinge body side The hooks 43 in the bearings 42 pass through the mounting holes B20 of the mounting portion B2 on the hinge body side so that the hooks 43 on the other side of the mounting portion B20 on the hinge body side contact each other. By the biasing force of the coil spring 45 between 43 (elastic return of the coil spring 45), each locking claw 43A rotates from between the bearings 42 in the direction of both side edges 422 and 424 of each bearing 42, and each side of each bearing 42 It protrudes outward from between the edges 422 and 424 and is elastically locked to the edges of the attachment hole B20 in the short side direction. Here, as shown in FIG. 15, in this hinge body 1, the center of rotation of each hook 43 is provided on the edge 431 side of one end of each hook 43, and the edge 433 of the other end of each hook 43 is Each hook 43 is formed in an arc shape in which the center of the circle is closer to the edge 431 at one end of each hook 43 than the center of rotation of each hook 43 and closer to the inner surface portion 434 than the center of rotation of each hook 43. As shown, as each locking claw 43A rotates outward, the arc-shaped portion of each locking claw 43A protrudes toward the edge of the mounting hole B20, and each edge of the mounting hole B20 in the short side direction is pushed out. As a result, the flange 411 of the flat surface 41 of the mounting base 4 (via the waterproof packing 61) is pressed against the entire periphery of the mounting hole B20 on one side of the mounting portion B2 on the hinge body side, The hinge body 1 is firmly attached and fixed to the attachment portion B2 on the hinge body side. In this way, the hinge body 1 can be reliably fixed to the housing B with one touch. FIG. 24 shows a case where this hinge body 1 is applied to two types of mounting plates having different thicknesses. Due to the shape of the locking claw 43A peculiar to the hook 43 of the hinge body 1, particularly the arc shape of the edge 433 at the other end, the arc-shaped portion of each locking claw 43A can be attached even if the thickness of the mounting plate is different. It can push out toward the edge part of hole B20, and can be made to bite reliably.

次に、図21に示すように、扉Dのヒンジ羽根側の取付部D1の上下に、ヒンジ羽根2を1つずつ取り付ける。なお、ヒンジ羽根2は、使用前の通常の状態では、一対の軸受52の間でフック53がフック53と一対の軸受52の底部との間のコイルスプリング55(図17参照)により各軸受52の各突出端521方向に押圧付勢されて、フック53の外面部532から他端の縁部533にかけて、すなわち、係止爪53Aが各軸受52の各突出端521間から外側に弾性的に突出される。なお、この状態は、フック53の内面部534側のストッパー535と一対の軸受52間の底部との係合により(図22参照)、フック53の各軸受52からの飛び出しが防止されて、保持される。
このヒンジ羽根2をヒンジ羽根側の取付部D1の取付孔D10に取り付ける場合、ヒンジ羽根2のブロック5Aを一対の軸受52を横向きにすることで取付プレートD1の取付孔D10の特に正面プレートd1側の開口D101に合せ、ブロック5Aをフック53とともにヒンジ羽根側の取付部D1の取付孔D10に正面プレートd1側の開口D101から差し込み、押し込む(ワンプッシュする)。
このようにすると、図21、図22に示すように、ヒンジ羽根2は、ブロック5Aの上下面の各溝56にヒンジ羽根側の取付部D1の取付穴D10の左側部プレートd2側の開口D102の各係止縁部D103が係合しながら、ブロック5Aの側面の各軸受52の各突出端521及び上下の各面が先端から中間へ、中間から基端へヒンジ羽根側の取付部D1の取付孔D10、すなわち正面プレートd1の開口D101の長辺方向及び短辺方向の各縁部を摺動しつつ、ヒンジ羽根側の取付部D1の取付孔D10(正面プレートd1の開口D101)を通過する。この間、各軸受52の各突出端521間から外側に突出されるフック53の係止爪53Aはヒンジ羽根側の取付部D1の取付孔D10(正面プレートd1の開口D101)の各長辺方向の縁部に接触して押圧され、係止爪53Aがフック53と一対の軸受52間の底部との間のコイルスプリング55の付勢力に抗して(コイルスプリング55を圧縮しながら)各軸受52間に向けて回動し各軸受52の各突出端521間に没入されていく。そして(ヒンジ羽根2が取付孔D10(正面プレートd1の開口D101)に押し込まれた瞬間)、ブロック5Aの各溝56とヒンジ羽根側の取付部D1の左側部プレートd2側の開口D102の各係止縁部D103が完全に係合し、係止爪5Aが完全に各軸受52の各突出端521間内に没入されて各軸受52がヒンジ羽根側の取付部D1の取付孔D10(正面プレートd1の開口D101)を完全に通過し、ヒンジ羽根取付ベース5は平面511、512全周縁部のフランジ513がヒンジ羽根側の取付部D1の一方の面側で取付孔D10の全周縁部に当接するとともに、各軸受52内のフック53はヒンジ羽根側の取付部D1の取付孔D10(正面プレートd1の開口D101)の通り抜けによりヒンジ羽根側の取付部D1の他方の面側でフック53と各軸受52間の底部との間のコイルスプリング55の付勢力(コイルスプリング55の弾性復帰)により係止爪53Aが各軸受52間から各軸受52の各突出端521方向に回動し各軸受52の各突出端521間から外側に突出されて、取付孔D10(正面プレートd1の開口D101)の長辺方向の縁部に弾性係止される。ここで、このヒンジ羽根2は、図18に示したように、フック53の回動中心がフック53の一端の縁部531側に設けられ、フック53の他端の縁部533は円の中心を各フック53の回動中心よりも各フック53の一端の縁部531に近くかつ内面部534寄りの位置におく円弧状に形成されることで、フック53は、図22に示すように、係止爪53Aの外側への回動とともに係止爪53Aの円弧状の部分が取付孔D10の縁部に向けて迫り出して、取付孔D10の長辺方向の縁部に食い込み、これにより、ヒンジ羽根取付ベース5の平面51のフランジ513はヒンジ側の取付部D1の一方の面側で取付孔D10の全周縁部に圧接されて、ヒンジ羽根2がヒンジ側の取付部D1に強固に取り付け固定される。このようにしてヒンジ羽根2を扉Dにワンタッチで確実に固定することができる。図24にこのヒンジ羽根2を異なる厚さの2種類の取付プレートに適用した場合を示している。このヒンジ羽根2のフック53特有の係止爪53Aの形状、特に他端の縁部533の円弧形状により、取付プレートの厚さが異なる場合でも、各係止爪53Aの円弧状の部分を取付孔D10の縁部に向けて迫り出して確実に食い込ませることができる。
なお、このヒンジ羽根2にあっては、フック53のヒンジ本体1の各フック43とは異なる形状により、フック53、各軸受52を共にヒンジ本体1の各フック43、各軸受42よりも小型化することができ、扉の側部で角部に近い箇所にも簡易に取り付けることができる。
Next, as shown in FIG. 21, the hinge blades 2 are attached to the top and bottom of the attachment portion D1 on the hinge blade side of the door D one by one. In addition, in the normal state before use, the hinge blade 2 is arranged such that the hooks 53 are held between the pair of bearings 52 by the coil springs 55 (see FIG. 17) between the hooks 53 and the bottoms of the pair of bearings 52 . 521 of the hook 53 from the outer surface portion 532 of the hook 53 to the edge portion 533 of the other end, that is, the locking pawl 53A elastically outward from between the protruding ends 521 of the bearings 52. Protruded. In this state, the engagement between the stopper 535 on the inner surface 534 side of the hook 53 and the bottom portion between the pair of bearings 52 (see FIG. 22) prevents the hook 53 from jumping out of the bearings 52 and holds it. be done.
When the hinge blade 2 is attached to the mounting hole D10 of the mounting portion D1 on the hinge blade side, the pair of bearings 52 of the block 5A of the hinge blade 2 are turned sideways so that the mounting hole D10 of the mounting plate D1 is mounted particularly on the side of the front plate d1. , insert the block 5A together with the hook 53 into the mounting hole D10 of the mounting portion D1 on the side of the hinge blade through the opening D101 on the side of the front plate d1 and push (one push).
As shown in FIGS. 21 and 22, the hinge vanes 2 are fitted in the grooves 56 on the upper and lower surfaces of the block 5A, and the openings D102 on the left side plate d2 of the attachment holes D10 in the attachment portion D1 on the hinge vane side. While each locking edge D103 is engaged, each protruding end 521 of each bearing 52 on the side surface of the block 5A and each upper and lower surface are moved from the tip to the middle and from the middle to the base end of the mounting portion D1 on the hinge blade side. While sliding along the mounting hole D10, that is, the edges in the long and short side directions of the opening D101 of the front plate d1, it passes through the mounting hole D10 (opening D101 of the front plate d1) of the mounting portion D1 on the hinge blade side. do. During this time, the locking claws 53A of the hooks 53 protruding outward from between the protruding ends 521 of the bearings 52 are aligned in the longitudinal direction of the mounting holes D10 (the openings D101 of the front plate d1) of the mounting portion D1 on the hinge blade side. Pressed in contact with the edge, the locking pawl 53A engages each bearing 52 against the biasing force of the coil spring 55 between the hook 53 and the bottom between the pair of bearings 52 (compressing the coil spring 55). It rotates toward the middle and sinks into between each projecting end 521 of each bearing 52 . Then (at the moment when the hinge blade 2 is pushed into the mounting hole D10 (opening D101 of the front plate d1)), each groove 56 of the block 5A engages with the opening D102 of the mounting portion D1 on the hinge blade side on the left side plate d2 side. The stop edge portion D103 is completely engaged, the locking pawl 5A is completely retracted between the projecting ends 521 of the bearings 52, and the bearings 52 are inserted into the mounting holes D10 (front plate) of the mounting portion D1 on the hinge blade side. d1), and the flanges 513 on the entire periphery of the planes 511 and 512 of the hinge blade mounting base 5 are in contact with the entire periphery of the mounting hole D10 on one side of the mounting portion D1 on the hinge blade side. At the same time, the hook 53 in each bearing 52 passes through the mounting hole D10 (opening D101 of the front plate d1) of the mounting portion D1 on the hinge blade side, and the hook 53 and the hook 53 on the other side of the mounting portion D1 on the hinge blade side are connected to each other. Due to the urging force of the coil spring 55 between the bottoms of the bearings 52 (elastic return of the coil spring 55), the locking claws 53A rotate from between the bearings 52 toward the projecting ends 521 of the bearings 52, and the bearings 52 , and is elastically locked to the longitudinal edge of the mounting hole D10 (opening D101 of the front plate d1). Here, as shown in FIG. 18, in this hinge blade 2, the rotation center of the hook 53 is provided on the edge 531 side of one end of the hook 53, and the edge 533 of the other end of the hook 53 is located at the center of the circle. is closer to the edge 531 at one end of each hook 53 than the center of rotation of each hook 53 and closer to the inner surface portion 534. As the locking claw 53A rotates outward, the arc-shaped portion of the locking claw 53A protrudes toward the edge of the mounting hole D10 and bites into the edge of the mounting hole D10 in the long side direction. The flange 513 of the flat surface 51 of the hinge blade mounting base 5 is pressed against the entire periphery of the mounting hole D10 on one side of the hinge-side mounting portion D1, so that the hinge blade 2 is firmly mounted to the hinge-side mounting portion D1. Fixed. In this way, the hinge blade 2 can be reliably fixed to the door D with one touch. FIG. 24 shows a case where this hinge blade 2 is applied to two types of mounting plates having different thicknesses. Due to the shape of the locking claw 53A peculiar to the hook 53 of the hinge blade 2, especially the arc shape of the edge 533 at the other end, the arc-shaped portion of each locking claw 53A can be attached even when the thickness of the mounting plate is different. It can push out toward the edge part of the hole D10, and can be made to bite reliably.
In this hinge blade 2, the hook 53 and each bearing 52 are both smaller than each hook 43 and each bearing 42 of the hinge body 1 because the hook 53 has a different shape from each hook 43 of the hinge body 1. It can be easily attached to the side of the door near the corner.

そして、図23に示すように、筐体Bのヒンジ本体1と扉Dのヒンジ羽根2とをヒンジピン3を介して連結し、筐体Bに扉Dを取り付ける。
この場合、まず、ヒンジ本体1のヒンジ本体取付ベース4の間欠部48にヒンジ羽根2のヒンジ羽根取付ベース5のブロック5Aが嵌め込まれ、ヒンジ本体取付ベース4の上下ヒンジピン挿通部47U、47Dとヒンジ羽根2のブロック5Aのヒンジピン挿通部57が合わせられ、ヒンジピン3がヒンジ本体1の上のヒンジピン挿通部47Uからヒンジ羽根2のヒンジピン挿通部57を通して、ヒンジ本体1の下のヒンジピン挿通部47Dに挿通されて、ヒンジ本体1とヒンジ羽根2がヒンジピン3により連結され、筐体Bに扉Dが回動可能に取り付けられる。
Then, as shown in FIG. 23, the hinge main body 1 of the housing B and the hinge blade 2 of the door D are connected via the hinge pin 3, and the door D is attached to the housing B. As shown in FIG.
In this case, first, the block 5A of the hinge blade mounting base 5 of the hinge blade 2 is fitted into the intermittent portion 48 of the hinge body mounting base 4 of the hinge body 1, and the upper and lower hinge pin insertion portions 47U, 47D of the hinge body mounting base 4 and the hinge are fitted. The hinge pin insertion portion 57 of the block 5A of the blade 2 is aligned, and the hinge pin 3 is inserted from the hinge pin insertion portion 47U above the hinge main body 1 through the hinge pin insertion portion 57 of the hinge blade 2 and into the hinge pin insertion portion 47D below the hinge main body 1. The hinge main body 1 and the hinge blade 2 are connected by the hinge pin 3, and the door D is attached to the housing B so as to be rotatable.

以上説明したように、このワンタッチ取付ヒンジH2によれば、ヒンジ羽根2は、ヒンジ羽根側の取付部D1に、ヒンジ羽根側の取付部Dの他方向の面に形成され、ヒンジ羽根側のブロック5Aを一対の軸受52とともに嵌装可能な他方向の面側の開口D101とヒンジ羽根側の取付部D1の一方向の面に他方向の面側の開口に連通して形成され、ヒンジ羽根2のブロック5Aの各溝56に係合可能な2つの係止縁部D103を有する一方向の面側の開口D102とからなるヒンジ羽根側の取付孔D10を形成されて、ヒンジ羽根2は、ヒンジ羽根側のブロック5A及び一対の軸受52がフック53とともにヒンジ羽根側の取付孔D10の他方向の面側の開口D101にヒンジ羽根側の取付部D1の一方の面側から他方の面側に向けてワンプッシュで通されて、一方の面側で、ヒンジ羽根取付ベース5のフランジ513がヒンジ羽根側の取付孔D10の縁部周囲に圧接されるとともに、他方の面側で、ヒンジ羽根側の2つの溝56とヒンジ羽根側の取付孔D10の一方向の面側の開口D102の各係止縁部D103が係合し、ヒンジ羽根側のフック53の係止爪53Aがヒンジ羽根側の取付孔D10の他方向の開口D101の縁部又は縁部周囲に係止されて、ヒンジ羽根側の取付部D1に取り付けられ、扉などの部材にヒンジ羽根2を溶接や取付ねじを用いることなしにワンタッチで簡易に取り付けることができ、また、溶接や取付ねじを用いないことで、ヒンジ羽根2の取り付けに要する部品点数を大幅に削減し、コストの大幅な低減を図ることができる。 As described above, according to the one-touch mounting hinge H2, the hinge blade 2 is formed on the mounting portion D1 on the hinge blade side, on the other side of the mounting portion D on the hinge blade side, and on the block on the hinge blade side. An opening D101 on the side of the other direction to which 5A can be fitted together with a pair of bearings 52 and an opening on the side of the other direction are formed on the one side of the mounting portion D1 on the side of the hinge blade so as to communicate with the opening on the side of the other direction. A mounting hole D10 on the side of the hinge blade is formed with an opening D102 on the face side in one direction having two locking edges D103 that can be engaged with each groove 56 of the block 5A of the hinge blade 2. A blade-side block 5A and a pair of bearings 52, together with a hook 53, are inserted into an opening D101 on the other side of the hinge-wing-side mounting hole D10 from one side of the hinge-wing-side mounting portion D1 toward the other side. With one push, the flange 513 of the hinge blade mounting base 5 is pressed against the periphery of the mounting hole D10 on the hinge blade side on one surface side, and the hinge blade side on the other surface side. The two grooves 56 and the locking edges D103 of the opening D102 on one side of the mounting hole D10 on the hinge blade side engage with each other, and the locking claw 53A of the hook 53 on the hinge blade side engages with the mounting hole D10 on the hinge blade side. It is locked to the edge of the opening D101 in the other direction of the hole D10 or around the edge, and is attached to the attachment portion D1 on the side of the hinge blade, and the hinge blade 2 is attached to a member such as a door without welding or using attachment screws. It can be easily attached with one touch, and by not using welding or attaching screws, the number of parts required for attaching the hinge blades 2 can be greatly reduced, and the cost can be greatly reduced.

また、このワンタッチ取付ヒンジH2によれば、ヒンジ本体1は、既述の構成により、ヒンジ本体側の取付部B2にヒンジ本体側の一対の軸受42を嵌装可能にヒンジ本体側の取付孔B20を形成されて、ヒンジ本体1は、ヒンジ本体側の一対の軸受42が各係止爪43Aとともにヒンジ本体側の取付部B2のヒンジ本体側の取付孔B20に当該取付部B2の一方の面側から他方の面側に向けてワンプッシュで通されて、一方の面側で、ヒンジ本体取付ベース4のフランジ411がヒンジ本体側の取付孔B2の縁部周囲に圧接されるとともに、他方の面側で、ヒンジ本体側の各フック43の各係止爪43Aがヒンジ本体側の取付孔B20の縁部又は縁部周囲に係止されて、ヒンジ本体側の取付部B2に取り付けられるので、筐体などの部材にヒンジ本体1を溶接や取付ねじを用いることなしにワンタッチで簡易に取り付けることができ、また、溶接や取付ねじを用いないことで、ヒンジ本体1の取り付けに要する部品点数を大幅に削減し、コストの大幅な低減を図ることができる。 Further, according to this one-touch mounting hinge H2, the hinge body 1 has mounting holes B20 on the hinge body side so that the pair of bearings 42 on the hinge body side can be fitted into the mounting portions B2 on the hinge body side. In the hinge body 1, the pair of bearings 42 on the hinge body side are inserted into the mounting holes B20 on the hinge body side of the mounting portion B2 on the hinge body side together with the locking claws 43A on one side of the mounting portion B2 on the hinge body side. The flange 411 of the hinge body mounting base 4 is pressed around the edge of the mounting hole B2 on the hinge body side on one side, and the other side On the other hand, each locking claw 43A of each hook 43 on the hinge body side is locked to the edge of or around the edge of the mounting hole B20 on the hinge body side, and attached to the mounting portion B2 on the hinge body side. The hinge body 1 can be easily attached to a member such as a body with one touch without using welding or mounting screws, and by not using welding or mounting screws, the number of parts required for mounting the hinge body 1 can be greatly reduced. can be reduced to 200,000, and the cost can be significantly reduced.

また、このヒンジH2はさらに次のような利点を有する。
(1)ヒンジ羽根2のフック53は、一端の縁部531側に回動中心として軸挿通部530が設けられ、他端側の縁部533が円の中心を回動中心よりも一端の縁部531に近くかつ内面部534寄りの位置におく円弧状に形成されることで、このヒンジ羽根2をヒンジ羽根側の取付部D1の取付孔D10に通しワンプッシュすると、係止爪53Aの外側への回動とともにこの係止爪53Aの円弧状の部分を取付孔D10の縁部に向けて迫り出して、取付孔D10の縁部に食い付かせることができ、これにより、ヒンジ羽根取付ベース5の平面51のフランジ511をヒンジ羽根側の取付部B2の取付孔B20の全周縁部の周辺に圧接させ、ヒンジ羽根側の取付部B2をヒンジ羽根取付ベース5とフック53との間で締め付けて、ヒンジ羽根2をヒンジ羽根側の取付部B2に確実に固定することができる。
(2)ヒンジ羽根2のフック53は、外面部532が各軸受52の各突出端521と平行に形成され、一端の縁部531が断面略V字形の突状に形成され、他端の縁部533が円弧状に形成され、内面部534が外面部532と対称的に外側一方の側縁部532と平行よりも少し開く方向に向けて形成されることで、フック53を角形の一対の軸受52内に各係止爪53Aのみが各軸受52の各突出端521間から出没可能に配置することができる。
この場合、フック53の内面部534の一端側を傾斜面とし、これが一対の軸受52の底部に係合されて、フック53の各軸受52から突出方向への過度の回動を規制されるので、フック53の各軸受52からの飛び出しを確実に防止することができる。
また、この場合、フック53の内面部534に筒状の孔536が形成され、ばね部材としてコイルスプリング55を採用され、コイルスプリング55が一端をフック53の孔536に保持され、他端をヒンジ羽根側の一対の軸受52間の底部に保持されて、フック53と各軸受52間との間に介装されるので、フック53を簡単な構造で各軸受52の各突出端521方向に確実に回動付勢することができる。
さらに、この場合、フック53の孔536は、一対の軸受52がフック53とともにヒンジ羽根側の取付部D1の取付孔D10に通される前又は後で、フック53の係止爪53Aが各軸受52の各突出端521間から突出されたときに、コイルスプリング55を取付ベース5側に凸の円弧状に変形案内可能に、各フック53の内面部534に対して所定の角度を付けて形成され、かつ各孔536の各フック53の一端の縁部531側又は他端の縁部533側の内周面の一部が、一対の軸受52がフック53とともにヒンジ羽根側の取付部D1の取付孔D10に通される間で、フック53の係止爪53Aが各軸受52の各突出端521間に没入されたときに、コイルスプリング55をヒンジ羽根取付ベース5とは反対側に凸の円弧状に変形案内可能に、孔536の奥側から開口側に向けて漸次拡径される所定の角度の傾斜を付けて形成されるので、コイルスプリング55の伸縮変形を良好にし、フック53の係止爪53Aを各軸受52の各突出端521間から確実かつ円滑に出没させることができる。
(3)ヒンジ本体1の一対のフック43はそれぞれ、一端の縁部431側に回動中心として軸挿通部430が設けられ、他端側の縁部433が円の中心を回動中心よりも一端の縁部431に近くかつ内面部434寄りの位置におく円弧状に形成されることで、このヒンジ本体1をヒンジ本体側の取付部B2の取付孔B20に通しワンプッシュすると、各係止爪43Aの外側への回動とともにこの係止爪43Aの円弧状の部分が取付孔B20の縁部に向けて迫り出して、取付孔B20の縁部に食い付かせることができ、これにより、ヒンジ本体取付ベース4の平面41のフランジ411をヒンジ本体側の取付部B2の取付孔B20の全周縁部に圧接させ、ヒンジ本体側の取付部B2をヒンジ本体取付ベース4と一対のフック43との間で締め付けて、ヒンジ本体1をヒンジ本体側の取付部B2に確実に固定することができる。
この場合、一対のフック43の内面部434に筒状の孔436が形成され、ばね部材としてコイルスプリング45を採用され、コイルスプリング45が両端を各フック43の各孔436に保持されて各フック43間に介装されるようにしたので、各フック43を簡単な構造で各軸受42の両側縁部422、424方向に確実に回動付勢することができる。
また、この場合、一対のフック43の各孔436は、一対の軸受42が各フック43とともにヒンジ本体側の取付部B2の取付孔B20に通される前又は後で、各フック43の各係止爪43Aが各軸受42の両側縁部422間、424間から突出されたときに、コイルスプリング45を取付ベース4側に凸の円弧状に変形案内可能に、各フック43の内面部434に対して所定の角度を付けて形成され、かつ各孔436の各フック43の一端の縁部431側又は他端の縁部433側の内周面の一部が、一対の軸受42が各フック43とともにヒンジ本体側の取付部B2の取付孔B20に通される間で、各フック43の係止爪43Aが各軸受42の両側縁部422間、424間に没入されるときに、コイルスプリング45をヒンジ本体取付ベース4とは反対側に凸の円弧状に変形案内可能に、孔436の奥側から開口側に向けて漸次拡径される所定の角度の傾斜を付けて形成されるので、コイルスプリング45の伸縮変形を良好にし、各フック43の各係止爪43Aを各軸受42の両側縁部422間、424間から確実かつ円滑に出没させることができる。
Further, this hinge H2 has the following advantages.
(1) The hook 53 of the hinge blade 2 is provided with the shaft insertion portion 530 on the side of the edge portion 531 at one end as the center of rotation, and the edge portion 533 on the other end side is positioned so that the center of the circle is closer to the edge of the one end than the center of rotation. By forming the hinge blade 2 in an arc shape near the portion 531 and near the inner surface portion 534, when the hinge blade 2 is passed through the mounting hole D10 of the mounting portion D1 on the hinge blade side and one push is performed, the outer side of the locking claw 53A is pushed. The arc-shaped portion of the locking claw 53A protrudes toward the edge of the mounting hole D10 as it rotates to the right, and can be made to bite into the edge of the mounting hole D10. The flange 511 of the flat surface 51 of 5 is pressed against the periphery of the mounting hole B20 of the mounting portion B2 on the hinge blade side, and the mounting portion B2 on the hinge blade side is tightened between the hinge blade mounting base 5 and the hook 53. Thus, the hinge blade 2 can be securely fixed to the mounting portion B2 on the hinge blade side.
(2) The hook 53 of the hinge blade 2 has an outer surface portion 532 formed parallel to each protruding end 521 of each bearing 52, an edge portion 531 at one end formed in a protruding shape having a substantially V-shaped cross section, and an edge portion at the other end. The portion 533 is formed in an arc shape, and the inner surface portion 534 is symmetrical with the outer surface portion 532 and is formed in a direction that is slightly more open than parallel to one of the outer side edge portions 532 , thereby forming the hook 53 into a pair of square hooks. Only the locking claws 53A can be arranged in the bearings 52 so as to protrude from between the projecting ends 521 of the bearings 52 .
In this case, one end side of the inner surface portion 534 of the hook 53 is formed as an inclined surface, and this is engaged with the bottom portions of the pair of bearings 52 to restrict excessive rotation of the hook 53 in the projecting direction from the bearings 52. , the hooks 53 can be reliably prevented from jumping out of the bearings 52 .
Further, in this case, a cylindrical hole 536 is formed in the inner surface portion 534 of the hook 53, and the coil spring 55 is employed as the spring member, one end of which is held in the hole 536 of the hook 53, and the other end of which is hinged.
