摘要：A portable image projector is provided with a vertically elongated tower
configuration to substantially reduce its vertical footprint when it is placed on a
horizontal support surface for use. A stabilizing foot is positioned below the housing
portion of the projector and is horizontally pivotable between a retracted orientation in
which the foot is disposed within the vertical footprint of the projector housing, and an
extended orientation in which the foot projects outwardly beyond opposite sides of the
projector housing. The stabilizing foot is pivotally secured to the bottom ends of a
spaced pair of arcuate elevating leg members that extend upwardly through openings in
the bottom side of the housing. The leg members are vertically movable through the
housing openings between retracted and extended positions and are resiliently biased in
a downward direction relative to the housing. A latch mechanism releasably locks the
legs in a selected vertical orientation and may be operated to selectively permit
retraction or extension of the legs in a manner controllably adjusting the pivotal
elevation of the lens portion of the projector.
