  • Patent number: 8033229
    Abstract: An adjustable projector stand is provided for supporting a video or still image projector. The projector stand is adjustable in pitch and tilt for positioning and leveling images projected on a screen in a manner that compensates for uneven support structures, such as tilted tables and poorly placed screens. The device may be powered manually by the user or by battery through the use of a motor. The projector stand generally consists of a platform with two legs, each of which is formed by two pivotally joined rods. Each leg is in direct rotational communication with a threaded rod disposed within the platform. Each rod is in turn coupled to a means for rotation, which may consist of a manually rotated knob or a battery powered motor. The raising and lowering of one leg may be performed independent of the other in order to allow the projector stand to be leveled on an uneven surface.
