System for removably attaching a center staybar to a window frame

Abstract

This invention provides a removable staybar that is securely attached to the window frame and removed easily, with minimal effort after installation of the window, so that the full perimeter of the window frame can be opened and unobstructed for passage of bulky items therethrough. The staybar includes two opposing ends each having a groove and surrounding ramped inner faces. These grooves each pass over a web on a respective attachment member that is fixedly mounted to a side of the window frame. Each web on an attachment member supports a corresponding pair of ramped faces. The ramped faces of each attachment member are oriented so that, when each end of the staybar is moved onto a respective attachment member, the engaging ramped faces cause the ends of the staybar to be forcibly driven toward the adjacent inner-facing sides of the window frame for a tight, abutting fit between the frame faces and respective staybar ends. The staybar is removably secured to the attachment members using a fastener (a screw) on each end that passes through the staybar and into the attachment member. This further drives the mating ramped faces over each other to force each staybar end against the adjacent frame face.
