    摘要： A window operator has a prime mover for opening and closing of a window, with the prime mover being drivingly connected to a drive output member through an intermediate gear structure. A clutch device in the drive structure senses the torque applied to the drive output member in a window closing operation and a switch operable by the clutch is effective to deenergize the prime mover when the torque applied to the output member reaches a predetermined value. The switch can be adjustably located relative to the clutch whereby the predetermined value at which the motor will be deenergized may be varied in order to obtain a desired tension on a member connected to the closed sash of the window, such as a chain connected to the sash of a skylight window.

    摘要翻译： 窗户操作者具有用于打开和关闭窗户的原动机，原动机通过中间齿轮结构驱动地连接到驱动输出构件。 驱动结构中的离合器装置在窗关闭操作中感测施加到驱动输出构件的扭矩，并且当施加到输出构件的扭矩达到预定值时，通过离合器可操作的开关有效地使原动机断电。 开关可以相对于离合器可调节地定位，从而可以改变电动机将被断电的预定值，以便在连接到窗户的闭合窗框的构件上获得期望的张力，诸如连接到 窗帘的天窗。
