Enhanced Lift-Tilt Swivel Monitor Stand

      Disclosed is a design for a Lift-Tilt-Swivel (LTS) monitor
stand to improve on an existing type.  Resulting benefits are reduced
field failures, fewer components simpler packing easier handling and
adjustment by both user and plant.

      With a current LTS product there are occasional field instances
resulting of total gas strut failure if a strut seal fails in
collapse of the unit on the customer's desk.  This revised design
uses a gas strut and lead screw method which eliminates the
possibility of sudden collapse.

      The current design of an LTS is a swivel base with a boom arm
giving the lift and tilt features which are operated through
individual gas springs.  The desired position can be sustained by the
use of a brake lever.  The unit is operated by releasing the brake
lever and moving the monitor to the required position.  When the
height and tilt position is attained the brake lever is moved to the
"lock" position.  Height adjustment often requires two hands to
position it.  Due to possible natural gas loss and field mis-use the
current design has potential failure weakness's in lift/tilt/brake
design.

      The new design eliminates potential lift collapse due to
operating via a leadscrew.  Tilt collapse is also reduced due to
operating through a friction tilt pad.  Inclusion of the leadscrew
acts as permanent lock and avoids the brake failure possible on the
original design.  Lower BM content and material usage reduces costs.
The unit can also be shipped flat-packed increasing the pallet
factor.  Only one hand is needed to operate and position the monitor
height and the unit does not jack knife when lifted.

      Fig. 1 shows the whole LTS in side elevation; Fig. 2 show a
plan view of the boom only.  The LTS comprises a tilt boom 2 hinged
at 16 to two vertical lugs 1A extending from a swivel turntable 1
which rotates about axis C/L on peripheral friction ring 20 secured
to a base surface.

      The boom 2 is an encased box structure with a height adjustment
knob 11 at its free end and a concave support shoe 12 hinged at 19 to
bearing lugs on the boom 2 free end.  A tilt bowl 14 with a convex
underside that matches the tilt bowl 12 concavity sits in bowl 12
held by gravity weight of the monitor 22 whose...
