摘要：A child safety device for a casement window includes a handle-driven gearreduction assembly having a sensor gear driven at a reduced speed relative to thehandle, a sensor arm driven by the sensor gear of the gear reduction assembly and a
slider movable between a stop position where rotation of the handle is prevented and aretracted position where rotation is allowed. A spring biases the slider towards the stopposition. The slider is held in the retracted position by a catch and is released by thesensor arm to prevent further opening of the window when the sensor gear reaches apredetermined location. The safety device resets when the window is closed and can beoverridden to allow full opening of the window by an adult. In the preferred design, thechild safety device is a cover that can replace the cover of an existing casement windowoperator.
