Abstract

Apparatus for adjusting the tilt angle of a flat display panel, such as a plasma panel, includes a strut and a rotatable stop member engaging one end of the strut. The strut has one end pivotally attached to a vertically extending support member which supports the display panel housing by means of a hinge attached to the back wall of the housing. The other end of the strut extends through an elongated slot extending generally in the vertical direction in the back wall of the housing and engages the rotatable stop member mounted on the back wall opposite the slot. The stop member has a smooth surface and a frictional surface provided with a number of detents. A lever attached to a shaft portion of the rotatable stop member extending below the bottom wall of the housing facilitates rotation of the stop to a position in which the strut is in sliding engagement with the smooth surface, allowing free adjustment of the tilt angle of the panel. A bias spring is biased to return the stop to a locking position in which the detents of the frictional surface engage the strut to hold the panel in a fixed tilt angle position.
