发明名称 Method and apparatus for cleaning tilt-in, double-hung windows
摘要 A static support device and associated method used to position tilt-in windows into an orientation that is ergonomically efficient for washing. The static support device includes an adjustable elongated member that is held in a vertical orientation by a free standing stand. A cross member is pivotably coupled to the top of the elongated member, wherein the cross member can be locked into an orientation that is generally perpendicular to the vertically supported elongated member. As a result, the overall static support device can assume a free standing T-shaped configuration. The static support device is positioned adjacent to a tilt-in window, whereby the sashes of the window can be tilted to a point where the sash rests upon the cross member. The cross member is padded to prevent damage to the sash. Furthermore, the slip stop elements extend upward from the cross member that engage the frame of the sash. The engagement between the sash and the cross member prevent the static support from inadvertently moving away from the sash as the window is being washed.
