ABSTRACT:
A security grille for disposition at a window, door or the like has at least a pair of vertically spaced tubular cross bars and a vertically extending tubular side member through which the grille may be fastened to a wall. Horizontal legs of a pair of angle members telescope into the ends of the cross bars while vertical legs of the angle members telescope into opposite ends of the side member. The construction enables horizontal expansion and contraction to accommodate to different installations, enables use of the side member with grilles having different cross bar spacings in the vertical direction and enables variation of the location of the attachment of the grille to the wall without displacement of the remainder of the grille. In the preferred form, the side member is fastened to the wall by latch mechanism having an enclosed cam which normally engages a pin on the side member but which can be actuated to release the pin and open the grille with a single movement of an actuator lever.
