Abstract
A mounting connection for a projection lens barrel in an image projection system is provided that includes a housing having an integral mounting portion for the projection lens barrel. The mounting portion has integral guide members formed thereon that cooperate with helical guide slots formed in an end of the projection lens barrel. A collet located between the projection lens barrel and the housing mounting portion is movable between a first position in which the collet frictionally engages the mounting portion to hold the projection lens barrel held stationary and a second position in which the collet is free of engagement with the mounting portion so that the projection lens barrel is free to be rotated to advance and retract to an adjusted position.
