THREE-PIPE HINGE
PROBLEM TO BE SOLVED: To provide a three-pipe hinge so as not to generate an abnormal sound from between pipe parts by use, or so as not to abrade an end surface of the pipe part in an abnormal state by an unbalanced load, in the three-pipe hinge of combining the three pipe parts.SOLUTION: A three-pipe hinge comprises a frame side blade 1 having an upper pipe part 3 and a lower pipe part 4 and a door side blade 2 having a pipe part 5 incorporated between these upper-lower pipe parts. Caps 7 and 8 are fixed to an end surface of the upper pipe part and the lower pipe part of the frame side blade. A shaft 6 is inserted into-fixed to the pipe part 5 of the door side blade, and the tip of the shaft vertically exposed from the pipe part is vertically slidably and rotatably inserted into the upper pipe part and the lower pipe part. The lower end of the shaft 6 rotatably and slidably contacts with an inner surface of the cap 8, and a clearance is formed between a lower end surface of the upper pipe part 3 and an upper end surface of the pipe paret 5 and between an upper end surface of the lower pipe part 4 and a lower end surface of the pipe part 5.
【課題】３個の管部を組み合わせた三管丁番において、使用により管部間から異音を発生したり、偏荷重により管部の端面が異常な状態に磨耗しないようにした三管丁番を提供する。【解決手段】上管部３と下管部４を有する枠側羽根１と、これらの上下管部間に組み込まれる管部５を有する扉側羽根２を具備する。枠側羽根の上管部と下管部の端面にはキャップ７、８が固着されている。扉側羽根の管部５には軸６が挿入固定され、管部から上下に露出する軸の先端は上管部及び下管部に上下摺動かつ回動自在に挿入されている。軸６の下端がキャップ８の内面に回動可能に摺接するとともに上管部３の下端面と管部５の上端面間、及び下管部４の上端面と管部５の下端面間には間隙が形成されている。【選択図】図１
