Abstract: A window frame display stand includes a corner body having a pair of mutually perpendicular legs, and a pair of spaced feet on one of the legs for supporting the body on a support surface such that the one leg is parallel to the support surface and the other leg is perpendicular to the support surface. The legs have adjacent interior surfaces that are contoured, preferably with slots or notches, to receive and support a window frame corner. The legs on the corner body preferably are mirror images of each other. The feet preferably are removably mounted on the one leg of the corner body, most preferably by interference press fit of the corner body leg into slots on the feet.
Abstract: A double hung window is provided with a keeper on the upper pane that also provides an elongate surface for receiving a downward force for moving the upper pane. The keeper has a tongue provided on an inner side of a central web of the u-shaped member that forms the combined keeper and surface. The force-applying surface is provided on a vertically upper surface of the same central web. The force-applying surface is curved along a slight radius such that it comfortably accommodates the fingers of a user to provide the downward force.
