ABSTRACT:
The locking bar assembly of the present invention is adapted to lock horizontally slidable, overlapping window doors, such as patio doors, in closed position. One end of a locking bar is pivoted to a bracket, or pivotal member, for movement in between a stored vertical position and a horizontal locking position. A clasping member, carried by the bracket, resiliently retains the locking bar either in the vertical position, or against upward pivoting from its horizontal position. The bracket is so constructed that it can be secured to the sash or to the handle flange of one door when the two doors can be opened, or to the door opening frame when only one door can be opened.
