ABSTRACT:
An improved lockable window gate including an outer frame element adapted to be secured within a window frame and a swingable gate element pivotally mounted upon the frame element and having a locked coplanar position. An improved locking mechanism provides for multiple locking locations therebetween, thus making the forcing of the gate more difficult. The overall dimensions of the frame element are adjustable to accommodate window openings of variable height and width by means of telescopic elements above and to one side of the gate element.
