ABSTRACT:
An adjustable tripod stand having independently adjustable legs comprises a longitudinal extensible upright portion of telescoping tubular members, a plurality of collar members slidably mounted on the upright portion which are longitudinally adjustable relative to one another and to the upright portion for selective positioning thereon, and a plurality of movable leg members operatively connected to upper and lower collar members for selective independent longitudinal positioning and radial extension relative to the upright portion and to one another. When an upper leg supporting collar and the corresponding lower collar are moved toward each other on the upright portion, the bottom of the leg connected thereto will be extended radially outward independently of the other legs, and when the upper leg supporting collar and the corresponding lower collar are moved away from each other, the bottom of the leg connected thereto will be drawn radially inward independently of the other legs. The independent positioning of the legs may be at different distances from the upright portion or in different planes relative to the other legs and thus allows the stand to be erected in limited or confined areas or on multi-level surfaces. The independent positioning of the legs also allows the longitudinal axis of the stand to be tilted to an off-vertical axis position for positioning the center of gravity of the supported vehicle within the supporting legs.
