Patent ID: 8459679

Claim:
A pivot mechanism, comprising: a base member configured to be coupled to a first element and having a bottom wall, a pair of opposed side walls, and a pair of opposed end walls that collectively define a cavity, at least one of the end walls having a first aperture; a generally cylindrical rotating member configured to be coupled to a second element and having a side wall and a pair of opposed end walls, the rotating member at least partially positioned within the cavity in the base member, and at least one of the end walls having a second aperture; an elongate pin extending through the first and second apertures of the base member and rotating member and defining a pivot axis, wherein the rotating member is capable of rotating relative to the base member about the pivot axis to provide relative movement between the first and second elements; at least one key coupled to the elongate pin; and at least one keyway positioned on each of the base member and rotating member, wherein the elongate pin is movable in a direction generally parallel to the pivot axis between a secured position in which the rotating member is prevented from rotating relative to the base member, and a release position in which the rotating member is permitted to rotate relative to the base member, wherein the key engages the keyways of both the base member and rotating member when the elongate pin is in the secured position.
