Abstract: A single or opposite direction damper hinge has a casing rotatably enclosing a rotor. The rotor has a center cylindrical portion mounting a reduced outwardly projecting intermediate portion which in turn outwardly mounts a further reduced stop portion. The casing has a main inner cylindrical surface which is interrupted by an inwardly projecting reduced engagement portion. In one embodiment, all of the rotor center, intermediate and stop portions and the casing main inner surface are coaxial. The casing reduced engagement portion, however, has a larger radius than the outwardly projecting intermediate portion of the rotor and is eccentric to the rotor outer surfaces and the casing main inner cylindrical surface. In assembly for operation, the rotor is mounted coaxially in the casing with the exception of the casing engagement portion which, in this embodiment, has the larger radius and is eccentric to the rotor intermediate portion. The rotor intermediate portion radially faces the casing engagement portion with the surfaces progressively closing due to the casing engagement portion larger radius and eccentricity, and the rotor stop portion interfering with the casing engagement portion ultimately abutting through facing steps. Further, the rotor and casing, in a second form, may be somewhat reversed, that is, the rotor having a smaller radius and eccentricity on the mating surface and the casing having the concentric mating surface, the overall result being the same. Finally, if the hinge is operable in opposite clockwise or counterclockwise directions, both of the casing and rotor are formed symmetrically with diametrically opposite and closed positions, and operable the same in either direction.

Abstract translation: 单个或相反方向的阻尼器铰链具有可旋转地包围转子的壳体。 转子具有安装缩小的向外突出的中间部分的中心圆柱形部分，该中间部分又向外安装另外减少的止动部分。 壳体具有由向内突出的减小的接合部分中断的主内圆柱表面。 在一个实施例中，转子中心，中间和止挡部分以及壳体主内表面都是同轴的。 然而，壳体减小的接合部分具有比转子的向外突出的中间部分更大的半径，并且偏转到转子外表面和壳体主内圆柱表面。 在组装操作中，除了壳体接合部分之外，转子同轴地安装在壳体中，壳体接合部分在该实施例中具有较大的半径并且与转子中间部分偏心。 由于壳体接合部分的半径和偏心度较大，转子中间部分径向地面对壳体接合部分，表面逐渐闭合，并且转子停止部分与壳体接合部分干涉，最终与面对台阶相邻。 此外，第二形式的转子和壳体可能有些反转，即转子在配合表面上具有较小的半径和偏心度，并且壳体具有同心配合表面，总体结果相同。 最后，如果铰链在相反的顺时针方向或逆时针方向上可操作，壳体和转子两者都以对称的方式对称地形成为直径相对的和闭合的位置，并且可在任一方向上操作。
