Patent ID: 7614119

Claim:
A hinge comprising: a rotating bracket having two sides; a top; a bottom; two transverse arms being formed respectively on and protruding radially out from the sides of the rotating bracket at the top, and each transverse arm having a distal end; and a connecting sleeve formed on and protruding longitudinally from the distal end of the transverse arm; a longitudinal shaft formed coaxially on and protruding longitudinally from the bottom of the rotating bracket and having a top; and a bottom; a flange being formed coaxially on and protruding radially out from the bottom of the rotating bracket and the top of the longitudinal shaft and having a bottom surface; and a rotation limit mounted around the longitudinal shaft and attached to the flange; two shaft assemblies connecting respectively to the connecting sleeves of the rotating bracket, and each shaft assembly comprising a shaft being mounted securely in a corresponding connecting sleeve; and a barrel being mounted rotatably on the shaft; a stationary bracket being mounted around the longitudinal shaft of the rotating bracket and having a top surface; a bottom surface; and a central hole being mounted rotatably around the longitudinal shaft of the rotating bracket; a spacer assembly being mounted rotatably around the longitudinal shaft of the rotating bracket and securely on the stationary bracket and having a retaining cap attached to the longitudinal shaft, mounted rotatably against the bottom surface of the stationary bracket and having a top surface rotatably abutting the bottom surface of the stationary bracket; and a limiting spacer mounted rotatably around the longitudinal shaft and securely on the stationary bracket and having a top surface; and two stops formed on and protruding up from the top surface; and a flat contact surface being formed between the rotation limit of the rotating bracket and the limiting spacer of the spacer assembly to provide a flat contact when the rotating bracket rotates relative to the spacer assembly.
