ABSTRACT:
A removable window guard/hinge assembly consisting of a plurality of vertical bars secured to at least two substantially horizontal bars with attached hinges, designed for mounting inside a window frame structure on the interior of the window. One side of each hinge is attached to one end of each horizontal member of the window guard and the other side of each hinge is removably insertable into metal sleeves which are embedded in the vertical member of the window frame structure. The side of the window guard opposite the hinges is secured to the window frame by a suitable lock. This design prevents removal of the window guard while it is closed but allows easy removal when it is opened, by moving the window guard assembly horizontally so that the hinge members slide out of the sleeves which are embedded in the window frame structure. After removal of the window guard/hinge assembly from the window, the remaining holes in the window frame can be concealed with plugs.
