Dual Arc Actuated Retention Latch

      This disclosure features a simple, one piece, user friendly
plastic latch to retain computer feature cards during vibration and
shipping. The latch, when installed into the desk top computer
chassis, holds feature card engagement with the bus connector.  See
Figure B.

      The latch in the disengaged mode can be positioned in a "park"
or dock configuration which allows both hands to be free for removing
or installing feature cards.  See Figures C and D.  Downward force on
the handle portion controls the height and angle of arc radius
travelled by the latch tip, therefore, whether or not the tip will
"park" in the disengaged position.  The latch tip is guided and held
solidly against the cards by working through a rectangular hole in
the stamped chassis.

      The entire latch is self retained between the walls of the
chassis along with a retention tab protruding through a second slot
in the chassis.  This latch, which solved a shipping problem of
unconstrained cards, is intuitive and easy to use while installing or
removing cards.
