ABSTRACT:
A support system for the mounting/suspension/elevation of a commercial projector is disclosed. The projector support grasps the projector to be mounted at one of its surfaces (typically, the bottom surface) through the use of two support arms. The support arms are affixed to the projector surface though mounting screws or other equivalent fastening mechanisms. The support arms each feature an adjustment slot which runs substantially the entire length of the arms. The presence of the two slotted arms allows for a countless array of scissoring arrangements for the support arms. This allows for interconnection with/mounting of the vast majority of commercial projectors (which invariably feature differing constellations of mounting holes). The projector support also employs a primary mount to facilitate swiveling/positioning of the projector so that the unit is effectually oriented for projection.
