Lift for television or other visual display screen

A visual-display screen lift comprising:

• a base;
• a lower support member attached to the base;
• an upper support member having an upper end portion and a lower portion telescopically engaged with the lower support member;
• a visual-display-screen support member pivotably connected to the upper end portion of the upper support member for pivotably supporting a visual display screen thereon, the visual-display-screen support member having a home position aligning the visual-display-screen support member at a selected angular orientation with respect to the upper support member;
• a drive mechanism operatively connected to the upper support member for raising and lowering the upper support member;
• a sensor configured to detect an angular position of the visual-display-screen support member, the sensor being operatively connected to the drive mechanism by a controller such that operation of the drive mechanism depends upon the angular position of the visual-display-screen support member;
• a detent operatively connected to the upper support member and the visual-display-screen support member, the detent resisting movement of the visual-display-screen support member from the home position when the visual-display-screen support member is in the home position;
• and
• an upper platform fixed upon the upper end portion of the upper support member, and wherein the visual-display-screen support member is supported by a bearing operatively connected to the upper platform, and the detent comprises a detent ball disposed within the upper platform, a spring disposed within the upper platform to drive the detent ball outwardly with respect to the upper platform, and a detent hole disposed on the visual-display-screen support member for engaging a portion of the detent ball upon the visual-display-screen support member being in the home position.
