用于门扇或窗扇的驱动装置
摘要：
本发明涉及一种用于门扇、窗扇或类似物的驱动装置，其具有壳体、可移动地在壳体中引导的通过弹性单元加载的活塞和可转动地支承在壳体中的经由小齿轮齿条传动机构与活塞连接的从动轴。小齿轮齿条传动机构包括与从动轴连接的非圆的小齿轮，该小齿轮的齿部与活塞侧的对应齿部啮合。在此，小齿轮侧的齿部的有效杠杆臂长度在从0°直至预定的第一扇打开角度的初始的扇打开角度范围内从在扇打开角度为0°时相对较高的或最大的有效杠杆臂长度出发随着扇打开角度增大而减小，而小齿轮侧的齿部的有效杠杆臂长度从大于或等于预定的第一扇打开角度并且小于最大的扇打开角度的预定的第二扇打开角度开始随着扇打开角度增大而突然增大。
摘要（英）：

A drive for a wing of a door, a window or the like comprises a housing, a piston guided displaceably in the housing, acted upon by a spring unit, and a driven shaft rotatably mounted in the housing and connected to the piston via a pinion-rack and pinion gear. The pinion-rack and pinion gear comprises a non-circular pinion connected to the driven shaft, the toothing of which meshes with counter-toothing on the piston side. The effective lever arm length of the pinion-side toothing decreases in an initial wing opening angle range from 0 degree to a first predetermined wing opening angle starting from a relatively higher or maximum effective lever arm length at the wing opening angle of 0 degree with increasing wing opening angle, while from a second predetermined wing opening angle, the effective lever arm length of the pinion-side toothing is greater than or the same size as the first predetermined wing opening angle and is smaller than the maximum wing opening angle, and the second predetermined wing opening angle increases abruptly with increasing wing opening angle.
