Universal tap plate for mounting either heavy-weight or light-weight hinges

摘要

End portions (10) of a tap plate (A) are welded to a metal door frame (B) with welding projections (12). The tap plate (A) has a front face (18) which is recessed from a rabbet surface (22) of the door frame by a thickness (24) of a heavy-weight hinge leaf (26). Adjacent each of the tapped bores (30) for receiving a hinge leaf mounting bolt (32), a button (40) projects forward from the tap plate front face. The buttons project forward by a difference (54) between the thickness of the heavy-weight hinge leaf and a thickness (56) of a standard hinge leaf (58). Each of the buttons defines a necked-down portion (44) around its periphery. The projecting portion of the button is removed to mount a heavy-weight hinge leaf (FIG. 3). With the buttons still in place, a standard-weight hinge leaf is mounted to the tap plate with its front face flush with the rabbet surface of the door frame (FIG. 6).
