Description

本発明は、ドア用ヒンジに関し、特に、ドアを所定角度位置に開いた状態に保持できるようにした機構を備えるドア用ヒンジに関する。 The present invention relates to a door hinge, and more particularly, to a door hinge provided with a mechanism capable of holding a door in an open state at a predetermined angular position.

ドアを開かれた所定位置に保持するため機構を備えたドア用ヒンジは種々開発されている（例えば、特許文献１） Various door hinges having a mechanism for holding the door in a predetermined position opened have been developed (for example, Patent Document 1).

実用新案登録２５５８８７５Utility model registration 2558875

そのようなドア用ヒンジは、製作する段階で、ドアを所定の開放角度（例えば９０°の位置）で保持できるように設定するものであるが、実際にドアの設定を行った場合に、当該ドアの開放保持角度を製作時の設定通りに正確にすることは難しい。従って、例えば、観音開きのドアの場合に、両方のドアの開放保持位置が相互に異なり、外観上、好ましくないことが生じる場合もある。また、ドア設定場所によっては、障害物等のために、ドア用ヒンジの製作時点において設定された開放保持角度にドアを保持することができない場合も生じ得る。
本発明は、このような点に鑑み、ドアを所定の開放角度で保持できるように製作されたドア用ヒンジにおいて、その開放角度を適宜調整できるようにすることを目的とする。 Such a door hinge is set so that the door can be held at a predetermined opening angle (for example, a position of 90 °) at the stage of manufacture, but when the door is actually set, It is difficult to make the door opening holding angle exactly as set at the time of manufacture. Therefore, for example, in the case of a double door, the open holding positions of both doors may be different from each other, which may be undesirable in appearance. Further, depending on the door setting location, the door may not be held at the open holding angle set at the time of manufacturing the door hinge due to an obstacle or the like.
In view of such a point, an object of the present invention is to make it possible to appropriately adjust the opening angle of a door hinge manufactured so that the door can be held at a predetermined opening angle.

The second cylinder 18 to which the second blade 16 is fixed, the shaft 20 arranged concentrically with the first and second cylinders 14, 18, and the shaft 18 to fix the shaft to the second cylinder 18. Fixing means 22 and a shaft angular position holding means 24 for holding the door opened at a predetermined opening angle position at the same angular position.

図４及び図５は、シャフト角度位置保持手段２４の横断面図であり、図４はドアが閉止位置にあるときの状態、図５はドアが図４の位置から９０°反時計方向に回動されたときの状態を示している。
ずなわち、図４において、シャフト２０を中心にして、半径方向外側にある断面が環状の部材３０は、図１に示すように、第１筒体１４と第２筒体１６との間に設定された中間筒体であり、該中間筒体３０に対し、第１筒体１４はスプライン結合されて固定されており、第２筒体１８はその軸線を中心に回動可能に取り付けられている。図４において、該中間筒体３０とシャフト２０との間にある断面円形の部材３４は、シャフト２０と平行に延び、同シャフトの直径方向で相互に反対側にある一対のローラであり、断面円弧状の部材３６は、中間筒体３０及びシャフト２０に対して円周方向で相対的に摺動可能とされ、（図示しない）バネにより時計方向に付勢されている一対のローラ保持体である。 4 and 5 are cross-sectional views of the shaft angular position holding means 24. FIG. 4 shows a state in which the door is in the closed position, and FIG. It shows the state when moved.
In other words, in FIG. 4, the member 30 having an annular cross section on the outer side in the radial direction with the shaft 20 as the center is formed between the first cylindrical body 14 and the second cylindrical body 16 as shown in FIG. 1. The first cylinder 14 is fixed to the intermediate cylinder 30 by spline coupling , and the second cylinder 18 is attached to the intermediate cylinder 30 so as to be rotatable about its axis. Yes. In FIG. 4, a member 34 having a circular cross section between the intermediate cylinder 30 and the shaft 20 is a pair of rollers that extend in parallel with the shaft 20 and are opposite to each other in the diametrical direction of the shaft. The arc-shaped member 36 is a pair of roller holders that are slidable in the circumferential direction relative to the intermediate cylinder 30 and the shaft 20 and are urged clockwise by a spring (not shown). is there.

シャフト２０の外周面２０−１には、直径方向で反対側にある大きな第１円弧状凹部３８、該第１円弧状凹部の時計方向側の近接した位置にあり相互に直径方向で反対側にある一対の小さな第２円弧状凹部４０、第１円弧状凹部３８の反時計方向側の近接した位置にあり相互に直径方向で反対側にある一対の小さな第３円弧状凹部４２とが形成されている。

A pair of small second arc-shaped recesses 40 and a pair of small third arc-shaped recesses 42 that are located close to each other on the counterclockwise side of the first arc-shaped recess 38 and are opposite to each other in the diameter direction are formed. ing.
In addition, a pair of roller accommodating recesses 44 and a roller guide recess 46 are formed on the inner peripheral surface 30-1 of the intermediate cylinder 30 at positions facing each other in the diameter direction.

図４のドア閉止状態から、ドアが同図で見て反時計方向に回動されると、第１円弧状凹部３８に係合しているローラ３４は、シャフト２０とともに反時計方向に回動され、図４の状態から約３０度回動した時点で中間筒体３０の内周面に形成されたローラ収納凹部４４内に嵌合され、第１円弧状凹部３８から半径方向外側に出て、シャフト２０が続けて反時計方向に回動するのを許容する。このとき、ローラ３４は、ローラ保持部材３６によって反時計方向に付勢され、図示の位置に保持されている。第１円弧状凹部３８が図４に示す最初の位置から、約９０°反時計方向に回動して図５に示す状態になると、同シャフト２０の外周面２０−１に形成されている第２円弧状凹部４０がローラ３４に係合し、当該シャフト２０の回転が止められる。
このようにして、シャフト２０は回動の最初の時点から約９０°の開放回動位置でローラ３４によって捉えられて同位置に固定保持されることになる。 When the door is rotated counterclockwise as viewed in FIG. 4 from the door closed state of FIG. 4, the roller 34 engaged with the first arcuate recess 38 rotates together with the shaft 20 in the counterclockwise direction. 4 and is fitted into a roller storage recess 44 formed on the inner peripheral surface of the intermediate cylinder 30 when it is rotated about 30 degrees from the state of FIG. The shaft 20 is allowed to continuously rotate counterclockwise. At this time, the roller 34 is urged counterclockwise by the roller holding member 36 and is held at the position shown in the drawing. When the first arcuate recess 38 is rotated about 90 ° counterclockwise from the initial position shown in FIG. 4 to reach the state shown in FIG. The two arcuate recesses 40 engage with the roller 34, and the rotation of the shaft 20 is stopped.
In this way, the shaft 20 is caught by the roller 34 at an open rotation position of about 90 ° from the initial point of rotation and is fixedly held at the same position.

That is, as shown in FIGS. 1 to 3, the fixing means 22 has an annular member 50 fixed in the second cylindrical body 18 so as to surround the shaft 20, and the annular member 50 is On the upper side (in FIG. 1 and FIG. 2), there are a first inclined surface 52 and a second inclined surface 54 provided at an interval of approximately 180 ° in the circumferential direction of the annular member. Further, the fixing means 22 has a cylindrical support member 56 fixed to the shaft 20 at the upper end of the second cylindrical body 18, and the support member 56 has the first and second inclined surfaces 52, 54. Screw holes 56-1 and 56-2 are formed at corresponding positions, and the angular position adjusting member 58 and the fixing member 60 are threadedly engaged with the screw holes. The second inclined surfaces 52 and 54 are engaged with each other. In FIG. 1, reference numeral 66 indicates a lid member that closes an end of the second cylinder 18.

シャフト２０に対する第２筒体１８の軸線の周りでの角度位置を調節するには、まず、角度位置調節部材５８をその軸線の周りで回転し、同軸線方向での位置を決め、該角度位置調節部材５８の先端にある球体６２に上記第１傾斜面５２が係合するように、当該第２筒体を回動し、同第２筒体の角度位置を決める。次に、固定部材６０をその軸線を中心に回転することにより、同固定部材の先端にある球体６４を上記第２傾斜面５４に押し付けることにより、該球体６４と球体６２との間で、当該環状部材を固定保持し、シャフト２０に対して第２筒体を固定する。 In order to adjust the angular position around the axis of the second cylinder 18 with respect to the shaft 20, first, the angular position adjusting member 58 is rotated around the axis to determine the position in the coaxial line direction. The second cylinder is rotated so that the first inclined surface 52 is engaged with the sphere 62 at the tip of the adjustment member 58, and the angular position of the second cylinder is determined. Next, by rotating the fixing member 60 around the axis thereof, the sphere 64 at the tip of the fixing member is pressed against the second inclined surface 54, so that the sphere 64 and the sphere 62 are The annular member is fixed and held, and the second cylinder is fixed to the shaft 20.
