Snap Lock Fan Holder

       Disclosed is a rotary-actuated snap-lock fan holder.  The
disclosed invention is unique in that it accommodates ease of
assembly/disassembly of an axial flow fan into an electronics chassis
while minimizing air recirculation around the snap features.

      Current technology for the mounting of axial flow fans usually
consists of some form of multiple threaded fasteners.  This
technology results in high assembly cost, high service cost, and high
part count.  The disclosed invention consists of a one-piece,
injection-molded plastic holder which allows the mounting of an axial
flow fan with a single, low-force movement.  The design also
facilitates easy removal/ replacement of the fan.

      To install the fan into the holder, the fan 5 is placed in the
holder 4, as shown in Fig. 1.  The fan is then rotated clockwise.
This deflects the spring clamps 2 upwards and deflects the spring
detents 1 downward. Rotation of the fan 5 is continued until the side
of the fan 5 contacts the locating rib 3 and the spring detent 1
snaps back to the original position.  The fan 5 can be removed from
the holder 4 by pulling the fan 5 away from the holder 4, free of
the spring detents 1, and rotating counter-clockwise.

      It can be seen in Fig. 2 that the fan 5 is located in
position between the spring detent 1 and the part of the locating rib
3 opposite the respective spring detent 1.  The fan is also clamped
by the spring clamps 2 to th...
