摘要： An over-center hinge for cabinet doors with a door-related hinge part in the form of a recess-mounting cup in which one end of each of two links is journaled whose other ends are journaled on a jamb-related hinge part in the form of an elongated supporting arm. On the side of the inner link facing the outer link a cam is articulated with its free end facing the supportring arm and is urged by a spring inserted between the cam and the pivot eye of the inner link against a counter-surface formed by a section of the inner wall of the supporting arm such that its face forces the hinge resiliently into the closed position upon passing a dead point in the closing movement. The section of the wall of the supporting arm that forms the counter-surface is provided at least in the surface area cooperating with the cam with a smooth, wear-resistant and friction-reducing surface.
摘要翻译：一种用于橱柜门的中心铰链，门铰链部分为凹座安装杯的形式，其中两个连杆中的每一个的一端被轴颈支承，其另一端以表格形式挂在与侧板相关的铰链部分上的细长支撑臂。在面向外部连杆的内部连接件的一侧，凸轮铰接着其自由端面向支撑臂，并且被插入在内部连杆的凸轮和枢转眼睛之间的弹簧相对于由一个部分形成的对置表面的支撑臂的内壁，使得当关闭运动中的死点通过时，其表面迫使铰链弹性地进入关闭位置。形成对置面的支撑臂的壁部分至少设置在与凸轮配合的表面区域中，具有光滑，耐磨和减摩的表面。
