Abstract

Disclosed is a flexible plastic baffle, including a pivot shaft and latches operating in opposite directions molded as integral portions thereof, used for controlling airflow in a personal computer. The baffle, which extends partially over the system board and memory modules, can be unlatched and pivoted out of the way to replace a system board or to install memory.

Air Baffle with Integral Hinge Pin and Latches

      Disclosed is a flexible plastic baffle, including a pivot shaft
and latches operating in opposite directions molded as integral
portions thereof, used for controlling airflow in a personal
computer.  The baffle, which extends partially over the system board
and memory modules, can be unlatched and pivoted out of the way to
replace a system board or to install memory.

      As shown in the figure, a personal computer system includes a
frame 1, a system board 2, and a baffle system to control the flow of
cooling air, consisting of a stationary baffle 3 mounted to frame 1,
and a pivotally mounted baffle 4.  This baffle 4 includes a pivot
shaft 5 extending between a pair of support tabs 6, and a pair of
latches 7 and 8, formed as integral parts thereof during a
thermoplastic molding process.  (In the figure, portions of
stationary baffle 3, frame 1, and system board 2 are cut away to
reveal portions of shaft 5 and latches 7 and 8).

      Shaft 5 is pivotally mounted to a stationary part of the
system, allowing the rotation of baffle 4.  Latch 7 includes a tip 9,
which extends through an aperture 10 in frame 1 to be fastened under
an edge thereof, while latch 8 includes a tip 11, which extends
adjacent to system board 2 to be fastened under an edge thereof.
When baffle 4 is latched in place in this way, latches 7 and 8 are
deflected toward one another, establishing forces acting in opposite
directions on fram...
