Description

本発明は、筐体に対する扉の建て付けを調整できる調整ヒンジに関する。 The present invention relates to an adjustment hinge capable of adjusting the installation of a door to a housing.

ヒンジは、筐体に取付けられる筐体側羽根と、扉に取付けられる扉側羽根と、筐体側羽根の端部の軸孔と扉側羽根の端部の軸孔に嵌挿される軸ピンとからなるものであるが、扉端面の回転軌跡が筐体側面と干渉しないように設計された適正位置に軸ピンが配置されていないときには、回転時に異音が発生したり、ヒンジ部品の片減り現象を招いたり、筐体と扉の間でシール部材を正しく圧縮できないことになる。 The hinge is composed of a housing-side blade attached to the housing, a door-side blade attached to the door, a shaft hole at the end of the housing-side blade, and a shaft pin inserted into the shaft hole at the end of the door-side blade. However, if the shaft pin is not placed at the proper position designed so that the rotation trajectory of the door end surface does not interfere with the side of the housing, abnormal noise may be generated during rotation or the hinge parts may be reduced. In other words, the seal member cannot be properly compressed between the housing and the door.

軸ピンが適正な姿勢位置に来ていない原因としては、筐体や扉の製作誤差や施工誤差、あるいは扉側や筐体側の固定用螺子孔の加工誤差などのヒンジ取付け当初からのものがある。また、扉の重量による回転モーメントがヒンジに集中する片持ち構造であるため、経年変化によりビス挿入孔にずれや変形が生じたことによる後発的なものがある。 The reason why the shaft pin is not in the proper posture position is from the beginning of the hinge installation, such as housing or door manufacturing error or construction error, or door or housing side fixing screw hole processing error. . In addition, since it has a cantilever structure in which the rotational moment due to the weight of the door is concentrated on the hinge, there is a later one due to the displacement or deformation of the screw insertion hole due to aging.

これらの原因で扉が前方に倒れ込んで筐体と扉の間に許容限度を超える隙間が生じたときには、前記軸ピンの姿勢位置を適正な状態に調整復帰させる必要がある。扉を外してヒンジを取付け直すという煩雑な方法によることなく、扉を筐体に取付けたまま調整作業を行なえるようにした調整ヒンジは、既に提案されている。 For these reasons, when the door falls forward and a gap exceeding the allowable limit is generated between the housing and the door, it is necessary to adjust and return the posture position of the shaft pin to an appropriate state. There has already been proposed an adjustment hinge that allows the adjustment work to be performed while the door is attached to the housing without using a complicated method of removing the door and reattaching the hinge.

従来の調整ヒンジとしては、固定枠体と扉体とのいずれか一方の部材に取付けるケース体と、このケース体に取付けられた一方の取付プレートと、この一方の取付プレートに上下方向の回動中心軸を介して開閉自在に軸支されて他方の部材に取付ける他方の取付プレートと、ケース体に前後方向に移動可能に設けられて一方の取付プレートを有する調整プレートと、前記ケース体に回動自在に設けられて前記調整プレートを前後方向に移動調整するカム体と、前記一方の取付プレートに形成した調整孔を介して、前記調整プレートに形成した螺子孔に進退自在に螺合された調整ボルトとで構成され、前記カム体の回動によって前記一方の取付プレートの取付け位置を前後方向に調整し、前記調整ボルトの回動によって、前記一方の取付プレートを左右方向に設定位置調整するものがある（特許文献１参照）。 As a conventional adjustment hinge, a case body attached to one member of a fixed frame body and a door body, one attachment plate attached to the case body, and vertical rotation on the one attachment plate The other mounting plate that is pivotally supported via the central shaft so as to be opened and closed and is attached to the other member, the adjustment plate that is provided on the case body so as to be movable in the front-rear direction, and has one mounting plate, A cam body that is movably provided and moves and adjusts the adjustment plate in the front-rear direction, and an adjustment hole formed in the one mounting plate, and is screwed into a screw hole formed in the adjustment plate so as to freely advance and retract. And adjusting the mounting position of the one mounting plate in the front-rear direction by rotating the cam body, and rotating the adjusting bolt to adjust the one mounting plate. Is used to adjust the set position in the lateral direction (see Patent Document 1).

しかしながら、この調整ヒンジでは、前記カム体の一端部に形成したカム操作体を直接回動操作して、カム軸のカム突部を偏心回動し、前記カム突部のカム面によって前記調整プレートのカム係合孔の開口縁部を押動するようにしたものであるから、前記カム体の回動操作に比較的大きな力を必要とし、軽快な調整作業が行なえない。 However, in this adjustment hinge, the cam operating body formed at one end of the cam body is directly rotated to eccentrically rotate the cam protrusion of the cam shaft, and the adjustment plate is adjusted by the cam surface of the cam protrusion. Since the opening edge of the cam engagement hole is pushed, a relatively large force is required for the rotating operation of the cam body, and a light adjustment operation cannot be performed.

また、前記一方の取付プレートは、前記調整ボルトの螺子軸部の進退動に連動して、前記調整プレートの軸受片に軸着された支軸を中心として回動するものであり、この回動軌跡の始端点と終端点の座標位置の差が調整範囲となるため、前記一方の取付プレートの左右方向への調整量はいまだ限定的なものにとどまっている。 Further, the one mounting plate rotates about a support shaft that is attached to the bearing piece of the adjustment plate in conjunction with the advancement and retraction of the screw shaft portion of the adjustment bolt. Since the difference between the coordinate position of the start point and the end point of the locus is the adjustment range, the adjustment amount of the one mounting plate in the left-right direction is still limited.

筐体側羽根に当接して配置され、ビス差入れ孔を形成してある前後方向調整板と、
扉側羽根に当接して配置され、筐体の前後方向に長い調整孔を形成してあるとともに、前面側に扉側羽根の従動カム斜面に当接する駆動カム斜面と、扉側羽根の前記ガイド用開口に嵌挿される突出部を形成してある左右方向調整板と、
前後方向調整板の前記ビス挿入孔から筐体側羽根の前記調整孔に挿通され、筐体側羽根を筐体側面に締付け固着する筐体側羽根用固定ビスと、
扉側羽根の前記ビス差入れ孔から左右方向調整板の前記調整孔に挿通され、扉側羽根を扉の端面に締付け固着する扉側羽根用固定ビスと、
筐体側羽根の螺子孔に螺合され、先端で前後方向調整板の側面を押圧する前後方向調整用螺子棒と、
扉側羽根の貫通孔から左右方向調整板の前記突出部の螺子孔に螺合され、先端が扉側羽根の内面壁を押圧する左右方向調整用螺子棒とからなる。 The adjustment hinge of the present invention is attached to the casing, the casing-side blades formed with a long adjustment hole in the front-rear direction of the casing,
A follower cam slope attached to the door and inclined with respect to the front-rear direction of the housing, a screw insertion hole, and a door-side blade formed with a long guide opening in the front-rear direction of the housing,
A vertical axial pin that is fitted in the shaft hole of the housing side blade and the shaft hole of the door side blade and connects the housing side blade and the door side blade so as to be relatively rotatable,
A front-rear direction adjustment plate arranged in contact with the casing-side blades and forming a screw insertion hole;

A housing-side blade fixing screw that is inserted from the screw insertion hole of the front-rear direction adjustment plate into the adjustment hole of the housing-side blade and fastens the housing-side blade to the side surface of the housing, and
A door-side blade fixing screw that is inserted from the screw insertion hole of the door-side blade into the adjustment hole of the left-right adjustment plate and fastens the door-side blade to the end surface of the door;
A screw rod for longitudinal adjustment that is screwed into the screw hole of the casing side blade and presses the side surface of the longitudinal adjustment plate at the tip;
It consists of a screw rod for left-right adjustment that is screwed into the screw hole of the protruding portion of the left-right adjustment plate from the through-hole of the door-side blade and the tip presses the inner wall of the door-side blade.

本発明によれば、筐体側羽根用固定ビスを適度に弛緩させた状態において、筐体側羽根の前記螺子孔に螺合した前後方向調整用螺子棒を回動操作すると、前後方向調整用螺子棒の先端が筐体側羽根用固定ビスで筐体側面に固着された前後方向調整板の側面を押圧し、この反作用として、前後方向調整板に対して筐体側羽根が筐体の前後方向に移動する。この調整作業後、筐体側羽根用固定ビスは再度締付けられる。
この筐体側羽根の筐体の前後方向への移動は、前後方向調整用螺子棒の回動操作による進退によってなされるものであるから、その移動範囲は前後方向調整用螺子棒の有効螺合長さに相当する。そのため、前記軸ピンの設定位置は筐体の前後方向に必要十分に広い範囲内で的確に調整されるのである。
このように筐体側羽根の移動は、前後方向調整用螺子棒の回動に伴うねじ運動によって行なわれるため、比較的小さな力で軽快に調整作業を行なうことができる。 According to the present invention, when the front and rear direction adjusting screw rod screwed into the screw hole of the housing side blade is rotated in a state where the housing side blade fixing screw is moderately relaxed, the front and rear direction adjusting screw rod is obtained. The tip of the blade presses the side surface of the front-rear direction adjusting plate fixed to the side surface of the case with the housing-side blade fixing screw. As a reaction, the case-side blade moves in the front-rear direction of the case with respect to the front-rear direction adjusting plate. . After this adjustment operation, the casing-side blade fixing screw is tightened again.
Since the movement of the casing-side blades in the front-rear direction is performed by advancing and retreating by the rotation operation of the front-rear direction adjusting screw rod, the moving range is the effective screwing length of the front-rear direction adjusting screw rod. It corresponds to. Therefore, the setting position of the shaft pin is accurately adjusted within a sufficiently wide range in the front-rear direction of the housing.
As described above, the movement of the casing-side blades is performed by the screw movement accompanying the rotation of the front-rear direction adjusting screw rod, so that the adjustment operation can be easily performed with a relatively small force.

また、扉側羽根用固定ビスを適度に弛緩させ、扉側羽根の前記貫通孔を通して左右方向調整用螺子棒を、先端が扉側羽根の内面壁を押圧した状態において回動操作すると、左右方向調整板の前記突出部の前記螺子孔と左右方向調整用螺子棒とのねじ運動がなされ、扉側羽根固定用ビスで扉端面に固着されている扉側羽根に対して、左右方向調整板の前記突出部が扉側羽根の前記ガイド用開口に沿って筐体の前後方向に移動し、このとき、左右方向調整板の前記駆動カム斜面と扉側羽根の前記従動カム斜面との間のカム作用によって、扉側羽根が筐体の左右方向に移動する。この調整作業後、扉側羽根用固定ビスは再度締付けられる。
この扉側羽根の筐体の左右方向への移動は、左右方向調整用螺子棒の回動操作で進退する左右方向調整板によってなされ、その移動範囲は前記駆動カム斜面のカム揚程に相当するものであるから、従来の回動軌跡の始端点と終端点の座標位置の差を利用した調整ヒンジと比較して、調整範囲が広くなる。すなわち、前記軸ピンの設定位置は筐体の左右方向に必要十分に広い範囲内で的確に調整されるのである。
また、左右方向調整板は左右方向調整用螺子棒のねじ運動によって駆進されるものであるから、カム体を直接に回動操作する従来の調整ヒンジと比較して、より小さな力で軽快に調整作業を行なうことができる。 Further, when the door-side blade fixing screw is loosened moderately and the left-right adjustment screw rod is rotated in a state where the tip presses the inner wall of the door-side blade through the through hole of the door-side blade, The screw hole of the protrusion of the adjustment plate and the screw rod for adjusting the left and right direction are screwed, and the door side blade fixed to the door end surface with the door side blade fixing screw The protrusion moves in the front-rear direction of the housing along the guide opening of the door-side blade, and at this time, a cam between the drive cam slope of the left-right adjustment plate and the driven cam slope of the door-side blade. By the action, the door-side blade moves in the left-right direction of the housing. After this adjustment operation, the door-side blade fixing screw is tightened again.
The movement of the door blades in the left-right direction is performed by a left-right adjustment plate that moves forward and backward by rotating the left-right adjustment screw rod, and the range of movement corresponds to the cam head of the drive cam slope. As a result, the adjustment range becomes wider compared to the conventional adjustment hinge that uses the difference between the coordinate positions of the start and end points of the turning trajectory. That is, the setting position of the shaft pin is accurately adjusted within a wide and necessary range in the left-right direction of the housing.
Also, since the left / right adjustment plate is driven by the screw movement of the left / right adjustment screw rod, it is lighter and lighter than conventional adjustment hinges that directly rotate the cam body. Adjustment work can be performed.

図示の実施例では、上位用調整ヒンジ３Ａと下位用調整ヒンジ３Ｂという２個のヒンジによって扉２が筐体１に取付けられている。上位用調整ヒンジ３Ａと下位用調整ヒンジ３Ｂの相違点は、図８と図１７を対比すれば明白なように、調整前の当初状態では、上位用調整ヒンジ３Ａの左右方向調整板４Ａは右側に最も移動した位置にあり、左右方向調整板４Ａの調整孔６Ａの左端内面が扉側羽根用固定ビス７に当接し、左右方向調整板４Ａの突出部５Ａが扉側羽根８のガイド用開口９の右端内面に当接しているのに対して、下位用調整ヒンジ３Ｂの左右方向調整板４Ｂは左側に最も移動した位置にあり、左右方向調整板４Ｂの調整孔６Ｂの右端内面が扉側羽根用固定ビス７に当接し、左右方向調整板４Ｂの突出部５Ｂが扉側羽根８のガイド用開口９の左端内面に当接していることである。 In the illustrated embodiment, the door 2 is attached to the housing 1 by two hinges, an upper adjustment hinge 3A and a lower adjustment hinge 3B. The difference between the upper adjustment hinge 3A and the lower adjustment hinge 3B is apparent from the comparison between FIG. 8 and FIG. 17. In the initial state before adjustment, the left-right adjustment plate 4A of the upper adjustment hinge 3A is on the right side. The left inner surface of the adjustment hole 6A of the left / right adjustment plate 4A is in contact with the door-side blade fixing screw 7, and the protruding portion 5A of the left / right adjustment plate 4A is a guide opening for the door-side blade 8. 9, the left-right adjustment plate 4B of the lower adjustment hinge 3B is in the most moved position on the left side, and the right-end inner surface of the adjustment hole 6B of the left-right adjustment plate 4B is on the door side. That is, the protrusion 5B of the left-right adjustment plate 4B is in contact with the inner surface of the left end of the guide opening 9 of the door-side blade 8 in contact with the blade fixing screw 7.

また、上位用調整ヒンジ３Ａと下位用調整ヒンジ３Ｂの相違点は、上位用調整ヒンジ３Ａの左右方向調整板４Ａの駆動カム斜面１０Ａのカム揚程が、下位用調整ヒンジ３Ｂの左右方向調整板４Ｂの駆動カム斜面１０Ｂのカム揚程よりも低く設定されていることである。これに対応して、図７と図１６を対比すれば明白なように、調整前の基底状態では、上位用調整ヒンジ３Ａの左右方向調整用螺子棒１２は、扉側羽根８の貫通孔１１の後端部の背後に位置しているのに対して、下位用調整ヒンジ３Ｂの左右方向調整用螺子棒１２は、扉側羽根８の貫通孔１１の前端部の背後に位置している。
このように当初の基底状態における左右方向調整板４Ａ，４Ｂの設定位置を上位用調整ヒンジ３Ａと下位用調整ヒンジ３Ｂとで変えたのは、一般的に経年変化による扉２と筐体１間の隙間の発生度合が、上位と下位とでは差異があるからである。 Further, the difference between the upper adjustment hinge 3A and the lower adjustment hinge 3B is that the cam head of the drive cam inclined surface 10A of the left and right adjustment plate 4A of the upper adjustment hinge 3A is different from the left and right adjustment plate 4B of the lower adjustment hinge 3B. It is set lower than the cam head of the drive cam slope 10B. Correspondingly, as is clear from a comparison between FIGS. 7 and 16, in the base state before adjustment, the left and right adjustment screw rod 12 of the upper adjustment hinge 3 A is formed in the through hole 11 of the door blade 8. The left and right adjustment screw rod 12 of the lower adjustment hinge 3 B is located behind the front end portion of the through-hole 11 of the door blade 8.
In this way, the setting positions of the left and right adjustment plates 4A and 4B in the initial base state are changed between the upper adjustment hinge 3A and the lower adjustment hinge 3B in general between the door 2 and the housing 1 due to secular change. This is because the degree of occurrence of the gap is different between the upper and lower levels.

上記の各相違点以外については、上位用調整ヒンジ３Ａと下位用調整ヒンジ３Ｂは同じであるから、各部材の参照番号にアルファベット「Ａ」、「Ｂ」の副字を使用しないで、両者の構成及び作用を以下に一括して説明する。
なお、筐体１の前後方向というのは、図８および図１７において紙面の水平線方向を意味し、筐体１の左右方向というのは、図８および図１７において紙面の鉛直線方向を意味している。 Except for the differences described above, the upper adjustment hinge 3A and the lower adjustment hinge 3B are the same. Therefore, without using the subscripts of the alphabets “A” and “B” for the reference numbers of the members, The configuration and operation will be described collectively below.
