Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an overhead door that may be opened/closed by moving a connected body of panels along a guide rail that has undergone interlayer deformation.SOLUTION: A connected body of panels 11 of an overhead door 10 has a plurality of panels 5 and an intermediate hinge 15a. An intermediate hinge 15a includes: a hinge shaft 46; a first shaft bearing 47 that rotatably supports the hinge shaft at both ends; a first shaft bearing member 48 disposed below the adjacent panels 5; a second shaft bearing 49 that rotatably supports a part of the shaft 46 between both ends; a second shaft bearing member 50 disposed above the adjacent panels 5; spaces 51, 52 formed above the shaft 46 between the shaft bearings 47, 49; and compression springs 53, 54 disposed on the shaft 46 in spaces 51, 52. When a pair of guide rails 2, 2 has undergone interlayer deformation, the adjacent panels 5 may be moved independently along a shaft direction of the shaft 46, resisting energizing force of the compression springs 53, 54.SELECTED DRAWING: Figure 7
【課題】層間変形した状態のガイドレールに沿ってパネル連接体の移動を可能とし、開閉できるオーバーヘッドドアを提供する。【解決手段】オーバーヘッドドア10のパネル連接体11は、複数のパネル5及び中間ヒンジ15aを有する。中間ヒンジ15aは、ヒンジ用軸46と、その両端部を旋回可能に支持する第一の軸受47を有し、隣接するパネル5の下方に配された第一の軸受部材48と、軸46の両端部間の一部を旋回可能に支持する第二の軸受49を有し、隣接するパネル5の上方に配された第二の軸受部材50と、両軸受47、49間の軸46上に形成された空間51、52と、空間51、52内の軸46に配された圧縮ばね53、54を有する。一対のガイドレール2、2が層間変形したときに、圧縮ばね53、54の付勢力に抗して、隣接するパネル5が互いに独立して軸46の軸方向に沿って移動可能となる。【選択図】図7 |
