  • Patent number: 4148453
    Abstract: A stacking stand for adjustably supporting at least one visual image projection device relative to a screen. The stacking stand comprises a support member and a support frame for carrying the projection device. The support frame is pivotably mounted on the support member by a ball and socket pivot joint located near the center of mass of the projection device. The pivot joint allows rotation of the support frame about pitch, roll and yaw axes. In addition, fastening means are provided for locking the support frame relative to the support member in various adjusted positions along the pitch, roll and yaw axes. Thus, an image projected by the projection device onto the screen may be superimposed with a target area on the screen by a rotary adjustment of the projection device along the pitch, roll and yaw axes.
