First Claim
Patent Images
1. A motorized lift for an electronic display, comprising:
- a reversible electric motor operably coupled to a first shiftable column and a second shiftable column, the coupling to the first column being direct and the coupling to the second column being indirect whereby operation of the electric motor in a first rotational direction acts to simultaneously extend the first and second columns and operation of the electric motor in a second and opposite rotational direction acts to simultaneously retract the first and second columns.
