Abstract: An assembly includes panels forming a bin or cabinet, and a flipper door operably attached to the bin by a pair of opposing modules. Each module includes a body forming a groove forming a curvilinear track along its upper edge, and the door includes a follower operably engaging the track. Each module further includes a spring-biased lever pivoted to the body of the module at a mid-lever pivot. A first leg of the lever is pivoted to the door at a door pivot, and an oppositely extending second leg is connected to a spring-biased force-generating device. The arrangement is constructed to counterbalance a weight of the door in most intermediate positions.

Abstract: An operator work station defined by a wall having a support assembly for mounting a monitor within a housing within an opening in the wall, the support assembly enabling the monitor to have four degrees of freedom. The support assembly includes a counterbalanced horizontal bar slidably disposed in the opening parallel to the wall for enabling the monitor to be raised and lowered parallel to the wall. Bearings rigidly secured to the bar receive rods rigidly secured to a horizontal plate, the movement of which enables the monitor to be moved perpendicular to the wall. A shaped plate pivotally connected between the horizontal plate and the housing enables the monitor to rotate about a vertical axis. Such rotation is limited by posts rigidly secured to the bar which engage the sides of the shaped plate when the shaped plate is rotated with respect to the wall.
