Abstract

Disclosed is a method of attaching a fan guard in front of a fan without the use of screws or other additional mounting hardware. Mounting screws could make contact with the cooling fan creating unwanted acoustic noise. In addition, this attachment method reduces initial installation time and number of parts required. To replace a defective fan, the fan guard must first be removed and this method reduces the service time.

Fan Guard Attachment

       Disclosed is a method of attaching a fan guard in front
of a fan without the use of screws or other additional mounting
hardware.  Mounting screws could make contact with the cooling fan
creating unwanted acoustic noise.  In addition, this attachment
method reduces initial installation time and number of parts
required.  To replace a defective fan, the fan guard must first be
removed and this method reduces the service time.

      Referring to the figure during the initial installation, the
cooling fan 17 is inserted halfway into the receiving pocket 2.  The
fan 1 is then plugged into the power supply (not shown).  The fan 1
is then fully inserted into its final location in the receiving
pocket 2, and the fan guard 3 is installed.  To install the fan guard
3, two opposite formed loops 4 are passed through the opening 5 in
the fan pocket 2 to occupy a position on the inside of the fan pocket
2.  The other two opposite formed loops 6 remain on the outside of
the opening 5 of the fan pocket 2.  The fan guard 3 is then rotated
in either direction until the two opposite formed loops 4 seat
themselves over the two circular extrusions 7 (see section B-B) and
the two opposite formed loops 6 seat themselves over the two circular
extrusions 8 (see section A-A).  The circular extrusions, 7 and 8,
position the fan guard 3, and because 7 is on the inside and 8 is
on the outside, it creates a spring force between the formed loops 4
and 6 for...
