Abstract
A mechanical package for an LCD projector includes approximately equally sized tower and enclosure portions. The tower portion is supported on forward protruding legs and contains optical and electronic modules that slide into its rear and are also accessible from the front of the enclosure portion. The enclosure portion supports on its front a removable projection screen and is mounted vertically offset on the tower portion. A triply folded optical axis provides a suitably long light pathway for projecting a large image on the projection screen without requiring the package to have an undue depth. To stack multiple packages vertically, side margins of the tower portion top surface include L-channels that receive the legs of a package stacked above. The enclosure portion further includes openings that receive the legs protruding from the tower portion stacked above. The legs are supported within the enclosure portion by sliding into U-brackets that are attached to the inner surfaces of the enclosure portion. Fasteners are passed through aligned holes in the legs and U-brackets to secure the vertically stacked packages. To stack multiple packages horizontally, the same fasteners that pass through aligned holes in the legs and U-brackets of the vertically stacked packages are also passed through the corresponding aligned holes in the legs and U-brackets of horizontally adjacent packages.
