Patent ID: 6871384

Claim:
An assembly for rotatably mounting a display unit to a surface for movement between a first angular position adjacent the surface, a second angular position spaced from the surface and a range of third annular positions spaced from the second annular position, the display unit having a display backing panel for supporting the display unit, the assembly comprising: a first hinge bracket for being connected to the surface; a first hinge mount for being connected to the display backing panel for rotation therewith; a first pintle secured to the first hinge mount for rotation therewith, the first pintle being rotatably connected to the first hinge bracket; a first friction element secured to the first hinge bracket, the first friction element rotatably engaging the first pintle and imparting a first resistive friction to the first pintle when the first pintle is rotated; and a first detent mechanism secured to the first hinge bracket and rotatably engaging the first pintle, the first detent mechanism releasably securing the first pintle in the second annular position and imparting a second resistive friction to the first pintle when the first pintle is rotated through the range of third angular positions, whereby the display unit rotates in a controlled manner from the first angular position to the second angular position due to a gravitational force, wherein the first detent mechanism comprises: a generally cylindrical-shaped first rocker secured to the first pintle for rotation therewith, the first rocker including a first circumferential surface having a first pair of generally opposing offset flats and a second pair of opposing offset arcuate surfaces; and a generally U-shaped first detent spring secured to the first hinge bracket, the first detent spring having a first pair of lever arms engaging the first circumferential surface of the first rocker, the first pair of lever arms cooperating with the first pair of generally opposing offset flats to releasably secure the first pintle in the second angular position and further cooperating with the second pair of opposing offset arcuate surfaces to impart the second resistive friction to the first rocker when the first pintle is rotated through the range of third angular positions.
