Patent ID: 7836552

Claim:
A hinge comprising: a pintle comprising a stem having a free end; a support board extending along a horizontal datum plane and comprising a planar support face and a first slot; and a sleeve comprising a first bracket, a second bracket, and a first mounting leg, wherein the first and second brackets are arranged opposite to and facing each other; wherein the sleeve is coupled to the support board by fitting the first mounting leg into the first slot, a stem receiving space is defined between the first bracket, the second bracket and the support face, and the free end of the stem is received into the stem receiving space; and wherein the pintle, support board, and sleeve are arranged such that the stem directly contacts the first and second brackets and the support face such that the stem is subject to constraint by the support face, and is further subject to a first resilient retention force applied by the first bracket in a first direction toward the support face and a second resilient retention force applied by the second bracket in a second direction toward the support face, wherein the first and second directions are different and symmetrical relative to the stem, so as to induce a predetermined rotational friction between the stem and the first and second brackets.
