In a hinge mechanism, a first hinge portion and a second hinge portion are urged toward predetermined angular relationships relative to one another. A force, directed outwardly from the first hinge portion, is applied by an axle pivotally connecting the first and second hinge portions and having a V-shaped tip against a V-shaped groove in the second hinge portion, urging the V-shaped tip and groove to engage. In addition to being urged toward predetermined angular relationships, the first and second hinge portions are kept in predetermined angular relationships until a torsional force is applied to one of the hinge portions to overcome forces keeping the V-shaped tip and groove in engagement.

A hinge mechanism comprising: a first hinge portion having a non-circular recess extending to a predetermined recess depth along a first axis substantially perpendicular to a side of the first hinge portion; a second hinge portion having a bore extending partially through the second hinge portion to a bottom at a predetermined bore depth and along a second axis substantially perpendicular to a side of the second hinge portion, the bottom of the bore having one or more substantially V-shaped grooves therein; an axle for pivotally connecting the first and second hinge portions comprising a flange portion having a first and a second side separated by a predetermined height in the direction of the first axis, the flange portion being disposed in, axially movable in, and non-rotatable relative to the non-circular recess, and an elongated portion having a predetermined length and a first and a second end, the second end of the elongated portion being disposed in, axially movable in, and rotatable relative to the bore, the elongated portion projecting, at the first end thereof, from the first side of the flange portion, the elongated portion being formed with a substantially V-shaped tip at the second end thereof, the substantially V-shaped tip being adapted to engage with the one or more substantially V-shaped grooves; and means for urging the substantially V-shaped tip of the elongated member against the bottom of the bore and toward engagement with the one or more substantially V-shaped grooves, wherein the first axis is aligned with the second axis to form a common axis, the first and second hinge portions being in a substantially abutting relationship along at least portions of the sides thereof, and the predetermined recess depth is at least as great as the predetermined height of the flange portion plus the predetermined length of the elongated portion, and the predetermined bore depth is less than the predetermined length of the elongated portion.
