Abstract:
An adjustable television stand comprising, in combination:a hollow base including a weighted bottom face, an upstanding side wall, and a top face, the top face having an annular slit formed therein thereby requiring a circular central portion of the top face to be supported via an L-shaped support mounted within an interior space of the base;an intermediate portion having a vertically oriented hollow cylindrical configuration slidably situated within the annular slit formed in the top face of the base, the intermediate portion having a horizontal circular divider mounted therein adjacent to an open top thereof;an upper support including a top plate having a planar square configuration with a stop formed along a front edge thereof and a rigid bracket mounted between side edges of the top plate for encompassing a television mounted on the top plate, the upper support including a post having a top end pivotally coupled about a horizontal axis to the top plate the post having a bottom end rotatably coupled about a vertical axis to a top face of the divider of the intermediate portion, and a hollow hemispherical portion mounted to a bottom surface of the top plate and slidably abutting an upper peripheral edge of the open top of the intermediate portion;a riser mechanism including a vertically oriented ball screw having a top end rotatably mounted to the divider of the intermediate portion and a bottom end in screwable engagement within a ball nut which is in turn rotatably coupled to the central portion of the base, the ball nut having a periphery with a plurality of teeth for engaging a gear of a first motor mounted within the base for selectively raising and lowering the intermediate portion and upper support;a rotator mechanism including a gear fixedly coupled in concentric relationship with a bottom of the post for engaging a gear of a second motor mounted on the divider of the intermediate portion for the purpose of selectively rotating the upper support about a vertical axis; anda tilt mechanism including a portion of a gear mounted to a bottom surface of the top plate of the upper support with a center thereof in alignment with the horizontal axis associated with the pivotal coupling between the post and the upper support, the tilt mechanism further including a third motor mounted on the post with a gear for engaging the portion of the gear thereby selectively tilting the upper support about a horizontal axis.
