Abstract: A tie bar and guide assembly for casement windows having a roll form tie bar that snaps on to the tie bar guide without extending through it. The tie bar has locating openings that engage tabs on the tie bar guide to locate and secure the guide prior to installation. The tabs are depressed and disengaged when fasteners are used to secure the tie bar assembly to the window frame. The tie bar can include rivet locking points located close to the top and bottom of the tie bar to provide better security and increased stability for preventing water and air infiltration. The rivet locking points can be adjustable to optimize the fit of the window sash within the frame. The snap-on design reduces the overall height of the tie bar assembly thereby enabling a closer fit of the sash within the frame and reducing the required width of the window frame needed to accommodate the locking mechanism.

Abstract: A casement window lock and tie bar assembly including a flexible guide pre-formed with an arcuate deflection. The guide receives a tie bar having a c-shaped cross-section. The arcuate deflection of the guide causes the guide to be frictionally held in an initial position on the longitudinal axis of tie bar. When fasteners are tightened to attach the guide to a window frame, the guide is flattened to enable the tie bar to freely slide on the guide.
