Lift-off type hinge

摘要

There is disclosed 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 cylindrical portion includes a coupling end (34) with a vertically extending octagonal channel (35) therethrough. The octagonal channel includes a vertically extending alignment ridge or tongue (36) and a centrally positioned, horizontally oriented, annular ridge (37). The hinge also includes an elongated cam follower (40) having a lower cam follower portion (41) with an octagonal exterior surface (43) terminating at a circumferential ledge or shoulder (44) positioned to abut and bear against the centrally positioned annular ridge of the coupling end. The lower cam follower portion also has a longitudinally extending groove (53) configured to receive the coupling end alignment tongue.

1. A hinge for use with a refrigerator door designed to rise relative to a surrounding door jamb when moved from a closed position to an open position, said hinge comprising,
a mounting flange assembly adapted to be mounted to the jamb of a refrigerator door, said mounting flange assembly having a cam and a rotating cam follower configured to mate with said cam and be moved longitudinally by relative rotational movement between said cam and said cam follower, said cam follower having an exterior surface and a longitudinally extending vertical, alignment groove extending inwardly from said exterior surface, and a strap assembly adapted to be mounted to a refrigerator door, said strap assembly being pivotally coupled to said mounting flange assembly and vertically movably relative to said mounting flange assembly through relative rotation between said cam of said mounting flange and said cam follower coupled to said strap assembly, said strap assembly including a strap having at least one strap mounting hole and a coupling end having a longitudinally extending vertical channel therein configured to receive at least a portion of said mounting flange cam follower, said vertical channel including a longitudinal, vertical alignment tongue extending into said channel and configured to be received within said longitudinally extending vertical alignment groove of said cam follower, whereby the proper alignment between the cam follower and the strap assembly may only occur when the vertical alignment tongue aligns with and is received within the vertical alignment groove.
