This relates to a folding door whose outer periphery is fitted to the -L lower end of the pivot support part 2, and its purpose is to provide a folding door that opens and closes smoothly and does not generate noise when opening and closing. There is something to do.

以下本考案を実施例により詳述する。The present invention will be explained in detail below with reference to Examples.

複数枚のパネル１の側端には上下方向に亘って略コ字状

る。A substantially U-shaped end frame 6 is fitted vertically to the side edges of the plurality of panels 1, and embedded protrusions 7 in the shape of both brim teeth are embedded in the panels 1 and fixed. A pivot support portion 2 having a C-shaped cross section is provided on the outside of the end frame 6 over the entire length in the vertical direction.

１を回動自在に連結しである。Further, pivot shaft portions 4 having a C-shaped cross section are provided at both ends of the U-shaped hinge piece 3 over the entire length in the vertical direction, and the pivot shaft portions 4 are attached to the pivot support portions 2, respectively. A plurality of panels 1 are rotatably connected by loose fitting.

またボールベアリングのようなベアリング５の内レース

ースの外周を枢支受部２の上下端に嵌合しである。Further, a mounting screw 8 is inserted into the inner periphery of the inner race of the bearing 5 such as a ball bearing, and the mounting screw 8 is screwed onto the upper and lower ends of the pivot shaft 4 so that the bearing 5 can be removed from the outside. The outer periphery of the race is fitted to the upper and lower ends of the pivot support part 2.

本考案は叙述の如く各枢支軸部の上下端にベアリングを
夫々回転自在に取付けると共にベアリングの外周を枢支
受部の上下端に嵌合しているので、各パネルを回転させ

のであって、開閉が軽くできるものであり、しかも枢支
受部と枢支軸部との間にギャップがあってもベアリング
により枢支受部と枢支軸部とがこすれ合わず、開閉時に
音がしないものである。As described above, in this invention, bearings are rotatably attached to the upper and lower ends of each pivot shaft, and the outer periphery of the bearing is fitted to the upper and lower ends of the pivot support, so each panel can be opened and closed by rotating. The bearing rotates smoothly and can be opened and closed easily, and even if there is a gap between the pivot support and the pivot shaft, the bearing allows the pivot support and the pivot shaft to be rotated smoothly. They do not rub against each other and do not make noise when opening or closing.

従って枢支受部や枢支軸部を剛性のある金属でなくて合
成樹脂で形成することもできる。Therefore, the pivot support portion and the pivot shaft portion can be made of synthetic resin instead of rigid metal.
