There is disclosed an anti-sag hinge (10) which includes a mounting flange assembly (12) pivotally coupled to a strap assembly (15). The strap assembly includes a strap (31) extending from a cylinder portion (32). The strap includes elongated mounting holes (69), an adjustment screw boss (70) having a passageway (71), and a moveable adjustment bracket (77) having an adjustment screw mounting flange (78) with a threaded screw hole (79) therein in which is threadably mounted an adjustment screw (80). The adjustment screw has a head (81), a bearing flange (82), a neck (83), and a threaded shaft (84). A removable spacer (86) has a U-shaped gripping portion (87) which is snap fitted onto a portion of the threaded shaft between the bearing flange and the adjustment bracket screw flange. The adjustment bracket includes four mounting holes (88) extending therethrough and generally in alignment with strap elongated mounting holes.
An anti-sag hinge comprising, a mounting flange assembly, and a strap assembly pivotally coupled to said mounting flange assembly, said strap assembly including a strap having at least one strap mounting hole, an adjustment bracket coupled to said strap for relative movement therebetween and having at least one bracket mounting hole alignable with said at least one strap mounting hole, and an adjuster coupled to said strap and said adjustment bracket, said adjuster being capable of varying the position of said adjustment bracket relative to said strap wherein said adjuster includes a first flange extending from said strap, a second flange extending from said adjustment bracket and having a threaded bolt mounting hole therein, and a threaded bolt coupled to said first flange for rotatable movement but preventing lateral movement of said threaded bolt along a longitudinal axis and threadably coupled to said second flange threaded bolt mounting hole, whereby threaded movement of the threaded bolt causes relative movement between the first and second flanges, and thereby relative movement between the adjustment bracket and the strap.
An anti-sag hinge comprising, a mounting flange assembly, and a strap assembly pivotally coupled to said mounting flange assembly, said strap assembly including a strap having door mounting holes therein and an adjustment flange, an adjustment bracket coupled to said strap for relative lateral movement therebetween, said adjustment bracket including a threaded adjustment mounting hole therein, and an adjuster having an elongated shaft threadably coupled to said strap adjustment flange to prevent longitudinal movement therebetween and including a threaded portion threadably received within said adjustment bracket threaded adjustment mounting hole, said adjuster being capable of varying the position of said adjustment bracket relative to said strap via rotational movement of said adjuster, and wherein said adjustment bracket includes door mounting holes aligned with said strap elongated door mounting holes.
An anti-sag hinge comprising, a mounting flange assembly, and a strap assembly pivotally coupled to said mounting flange assembly, said strap assembly including a strap having at least one strap door mounting hole, an adjustment bracket coupled to said strap for relative movement therebetween and having at least one bracket door mounting hole alignable with said at least one strap door mounting hole, and an adjuster coupled to said strap and said adjustment bracket, said adjuster being capable of varying the position of said adjustment bracket relative to said strap wherein said adjuster includes a first flange extending from said strap, a second flange extending from said adjustment bracket and having a threaded bolt mounting hole therein, a threaded bolt coupled to said first flange for rotatable movement, and a removable spacer mounted to said threaded bolt between said first flange and said second flange, said spacer being of a size which aligns said bracket door mounting hole with said strap assembly door mounting hole, whereby the spacer is utilized to maintain the alignment of the adjustment bracket with the strap during the mounting process and subsequently removed during the adjustment process of the anti-sag hinge.
