PIVOT HINGE
PROBLEM TO BE SOLVED: To provide a pivot hinge in which the tip of a pivot shaft is inserted to a bearing part to support a door by a frame body so that it can be rotated by an upper pivot hinge and a lower pivot hinge and the door can be removed and hung by arranging the tip of the pivot shaft of at least one of the hinges retractably from a case, enabling the door hanging operation to be easily performed by one person.SOLUTION: A pivot shaft 6 in a pivot hinge provided in the present invention is characterized in that a tip thereof is inclined, attached movably so that it is protruded and retracted from a case 9, and energized in the protruding direction and the rotating direction and that a side face thereof has an operation rod 24 protruding from a cam groove of the case. The cam groove comprises a vertical groove and a locking part 35 for keeping the operation rod detachable when the tip of the pivot shaft is protruded up to a position abutting to the side face of a bearing part. In hanging a door to a frame body, the pivot shaft retracts when the tip thereof abuts to the side face of the bearing part and protrudes to make the tip inserted to a shaft hole of the bearing part when the operation rod 24 is removed from the locking part 35.SELECTED DRAWING: Figure 2
【課題】ピボット軸の先端を軸受部に挿入して扉を上部ピボットヒンジ及び下部ピボットヒンジで回動可能に枠体に支持し、少なくとも一方のヒンジのピボット軸の先端をケースから出没可能に設けて扉を取り外し、吊り込み可能に設けたピボットヒンジにおいて、扉を吊り込む際、一人で簡単に作業できるようにしたピボットヒンジを提供する。【解決手段】ピボット軸６は、先端が傾斜し、ケースから出没するように移動可能に取り付けられ、突出方向及び回動方向に付勢され、側面にはケース９のカム溝から突出する操作杆２４が有る。カム溝は、縦溝と、上記ピボット軸の先端が軸受部の側面に当接する位置まで突出したとき、操作杆を離脱可能に保持する係止部３５を有する。扉を枠体に吊り込む際、ピボット軸の先端が軸受部の側面に当たると、ピボット軸は後退し、係止部３５から操作杆２４が外れるとピボット軸は突出して先端が軸受部の軸孔に挿入される。【選択図】図２
