Window sash pivot bar and method
View Patent ↗A pivot bar for a double hung window sash includes an elongated member having a knobbed end for engaging a window jamb or frame. The pivot bar has vertical and horizontal shields for completely covering the first and second apertures formed in the window sash. The pivot bar is “snap-fitted” into the first and second apertures which are formed with a conventional electric drill. The first aperture formed in the side of the sash is less than a complete circle in order for the drill bit to simultaneously form the second aperture in the bottom of the sash.
1. A method of installing a pivot bar having a vertical shield in a window sash that includes first and second sash stiles attached to opposing ends of a sash bottom, comprising:
forming a first opening in a side surface of the first sash stile at a bottom portion of the first sash stile, the first opening defining an incomplete circular opening in the side surface of the first sash stile, said incomplete circular opening being defined by a radius extending from a center point, wherein said center point is positioned above a bottom edge of the first sash stile;
forming a second opening, the second opening formed in a bottom portion of the sash bottom, the second opening being continuous with the incomplete circular opening of the first sash stile;
inserting the pivot bar into the incomplete circular opening of the first sash stile; and
closing the incomplete circular opening of the first sash stile with the vertical shield.
2. The method of claim 1 wherein the step of fondling a second opening comprises forming a rectangular opening in the sash bottom.
3. The method of claim 1 wherein the step of forming a first opening in the side surface of the first sash stile comprises drilling a hole in the side surface of the first sash stile.
4. The method of claim 1 wherein the pivot bar comprises a support attached to the shield.
5. The method of claim 1 further comprising securing the pivot bar to the sash bottom with a fastener.
6. The method of claim 1 whereby the steps of forming the first and second openings are performed by simultaneously drilling into the side surface of the first sash stile and the bottom portion of the sash bottom.
7. A method of installing a pivot bar having first and second longitudinal projections in a window sash that includes first and second sash stiles attached to opposing ends of a sash bottom, comprising:
forming an incomplete circular opening in a side surface of the first sash stile at a bottom portion of the first sash stile, said incomplete circular opening being defined by a radius extending from a center point, wherein the center point is positioned above a bottom edge of the first sash stile;
forming a rectangular opening in a bottom portion of the sash bottom, the incomplete circular opening being continuous with the rectangular opening; and
inserting the pivot bar into the incomplete circular and rectangular openings, and seating a portion of the sash bottom between the first and second longitudinal projections.
8. The method of claim 7 wherein the bottom portion of the first sash stile and the bottom portion of the sash bottom form an exterior corner of the window sash.
9. The method of claim 7 wherein the pivot bar includes a vertical shield which completely covers the incomplete circular opening.
10. A method of installing a pivot bar having first and second longitudinal projections and a vertical shield in a window sash that includes first and second sash stiles attached to opposite ends of a sash bottom, comprising:
forming a first opening in a side surface of the first sash stile at a bottom portion of the first stash stile, the first opening defining an incomplete circular opening in the side surface of the first sash stile, the incomplete circular opening being defined by a radius extending from a center point, wherein the center point is positioned above a bottom edge of the first sash stile;
forming a second, rectangular opening in a bottom portion of the sash bottom the second opening continuous with the incomplete circular opening;
inserting the pivot bar into the incomplete circular opening of the first sash stile and the rectangular opening such that a portion of the sash bottom is of the sash bottom inserted between the first and second longitudinal projections and
the incomplete circular opening of the first sash stile is closed by the vertical shield.
