Abstract:
1. A hinge assembly movable between an open position and a closed position, the hinge assembly comprising: a first hinge member including a first cylindrical body portion, a second hinge member including a second cylindrical body portion, a hinge pin assembly, the first and second cylindrical body portions overlying and housing the hinge pin assembly and having common longitudinal axes so that the first and second hinge members are rotatable to move the hinge assembly between the open and closed positions, the hinge pin assembly having upper and lower components, with the upper component mechanically tied to rotate with one of the hinge member body portions and the lower componont mechanically tied to rotate with the other of the hinge member body portions, each of the upper and lower components including an internal bores with a non circular cross section, and the axis of each internal bore being aligned with the axis of the other internal bore, a lock bar positioned within the internal bores of the hinge an assembly and having a size and cross section adapted to engage the internal bores of the hinge pin assembly, the lock bar being movable longitudinally between a first position and a second position, so that when the lock bar is in the first position it engages the internal bores of both hinge pin assembly components and the first and second hinge members are not rotatable relative to one another, and when the lock bar is in the second position it engages the internal bore of only one hinge pin assembly component and the first and second hinge members are rotatable relative to one another, and a magnetic latch cooperating between one of the first or second hinge members and the lock bar to hold the lock bar in one of the first or second positions.
