ABSTRACT:
An adjustable and pivotable window guard to be placed above a window inside a structure. The window guard provides an attractive appearance and excellent security. Hinge plates that have upwardly directed hinge tubes located thereon are secured on the inside wall proximal a window. A first window guard bracket having cooperating hinge bores is then placed on the hinge tubes so that it can pivot freely. The rectangular main central window guard is then placed over protruding members on the first window guard bracket and a second window guard bracket, also with similar protruding members, is inserted into the main central window guard on the opposite side from the first window guard bracket. Thus, all three of these elements are slidable horizontally in relationship to one another, which allows the user to adapt the device to variously sized windows. The second window guard bracket has a latch extending outwardly away from the main central window guard which fits into another latch receiving plate fixed to the wall on the opposite side of the window from the hinge plates. When novel locking pins are inserted into the first window guard bracket and the central window guard section in bores provided proximate the hinge plates, the assembly can not be pivoted open or forced because the locking pins butt up against the metal of the hinge plates. In alternative embodiments, multiple central sections may be placed in side by side relationship with one another to protect wider windows.
