Interlocking mounting package having separatable chassis for use in multiscreen projection displays

A stackable mechanical package for a digitally addressed projector (12N) includes a housing portion (22) having top and rear surfaces (44) that are shaped to form a contoured recess (46), and a pedestal portion (20) having bottom and front surfaces (60) that are sized to mate with the contoured recess when the package is in a shippable configuration. When a top side (50) of the pedestal portion is mated to a bottom side (32) of the housing portion, the stackable package is in a first operational configuration. Alternatively, when the stackable package is stacked below another similar stackable package (12F), the shippable configuration further forms a second operational configuration. The stackable package includes legs (24, 26) attached to and protruding from the pedestal portion to support the package apparatus in the first operational configuration or to fasten together the housing and pedestal portions when the package is in the shippable configuration. The fastening employs screws (64) that pass through mating sets of holes (62) in the legs and adjacent housing portions, which are then tightened with nuts (66). Multiple stackable packages may be arrayed vertically and/or horizontally for use in a multiscreen display system (10).
