Abstract:
A multi-position window comprising:a stationary window frame; a sash window frame positioned within said stationary window frame and non-simultaneously pivotable therein about a vertical axis and a horizontal axis; a drive train positioned between said sash window frame and said stationary window frame, said drive train being moveable between at least a first position enabling said sash window frame to be pivoted about said horizontal axis, and a second position enabling said sash window frame to be pivoted about said vertical axis; and a mechanical actuator operatively connected to said drive train to move said drive train, said mechanical actuator having a housing secured to and concealed within said sash window frame, a pinion gear rotatably mounted in said housing, a rack attached to said drive train, said pinion gear moveably engaging the rack, and a worm gear rotatably mounted for rotational movement in said housing and moveably engaging said pinion gear, whereby the rotational movement of said worm gear causes said pinion gear to move said rack and said drive train; wherein the engagement of the worm gear with the pinion gear and the pinion gear with the rack prevents the sash window frame from inadvertently pivoting about the horizontal axis unless the worm gear is rotated by an operator of the multi-position window.
