ABSTRACT:
A removable window bar for mounting inside a window structure, which window bar is characterized by a parallel top and bottom bar and crossbar, spaced by vertical bars. The bottom bar is removably seated in a pair of bar seats fastened in oppositely disposed relationship to the window facing. A pair of latch stays are also mounted in the window facing above and in spaced relationship with respect to the bar seats, respectively, and a rotatable latch is provided on each of the extending ends of the top bar, which latch is designed to removably engage the latch stay on each window facing and removably secure the removable window bar in position in the window. Rotational manipulation of each latch facilitates removal of the latch from the companion latch stay and lifting of the removably window bar from the bar seats, in order to remove the removable window bar from the window.
