A security bar for securely holding in a closed position a horizontally sliding door, such as a so-called patio door, for example, or a horizontally or vertically sliding window. The security bar of the invention consists of a massive metallic or plastic bar member, preferably square or rectangular in cross-section, pivotally supported at one end by means of a bracket from an inoperative position to an operative position wherein the free end of the bar member is supported by a clip with the longitudinal axis of the bar member substantially orthogonal to the rear edge of the frame of the sliding door or window and to a fixed structural surface such as the door or window jamb. Both ends of the bar member are formed with a curvilinear or cylindrical surface providing line engagement with the surfaces held apart by the bar member, such that any load resulting from an attempt to slide open the door or window is applied directly to the bar member in compression and not as a shear force applied through intermediary fastening members such as pivot pins or the like. When in an inoperative position, the bar member is held out of the way by a clip fastened to the same surface as the pivot support bracket.

A security bar for holding in a closed position a sliding panel provided with a frame dorsal surface adapted to be displaced substantially parallel to a jamb surface toward and away from said jamb surface during opening and closing of said panel, said safety bar comprising a bar member having each end formed with a curvilinear cylindrical face, and means at each end of said bar member for holding said bar member in an operative position preventing said frame dorsal surface of said sliding panel from being displaced towards said jamb surface with the longitudinal axis of said bar member substantially perpendicular to said frame dorsal surface and said jamb surface, wherein said means holding said bar member in said operative position comprises a pivotal support attached to one of said surfaces and a clip attached to the other of said surfaces, said pivotal support comprising a substantially U-shaped bracket member attached to said one of said surfaces and a pair of substantially parallel sidewalls one disposed on each side of said bar member at an end thereof, and a pivot pin member engaged through aligned apertures in said sidewalls and through said bar member proximate one of said curvilinear cylindrical end faces, and said clip comprises a generally U-shaped member having a mounting portion fastened to said other of said surfaces, said generally U-shaped member having a pair of opposite substantially parallel sidewalls each disposed on one side of said bar member and means in said clip sidewalls engageable with said bar member proximate the other of said curvilinear cylindrical end faces for supporting said bar member, wherein said apertures in said bracket member sidewalls, said pivot pin member and said supporting means in said clip are arranged to allow each curvilinear cylindrical end face of said bar member to provide line engagement with a planar surface corresponding to one of said surfaces and for opposing motion of one of said surfaces toward the other, and to cause said bar member to absorb in compression forces causing said motion, with said lines of engagement aligned substantially with said bar member longitudinal axis.
