Method and apparatus for mounting a fan guard

摘要

This invention is a quick attach fan guard for shroud type fans. A plurality of L-shaped slots are provided in the front and rear edges of the shroud with hooks with bends in the same are mounted on the fan guard so such bends lie a juxtaposed parallel plane to the interior of the shroud and the hooks engage the slots with such guard being rotated to lock the same to the shroud. At least one bolt is used to prevent undesirable counterrotation which might disconnect the guard from the shroud. Also malletable tabs are provided in a connector plate for the shroud to support the fan when used as a circulating fan. When the fan is used as an exhaust fan, a hook is mounted on the connecting plate for engaging an angle bracket on an adapter plate with a circular opening therein. Pivotable tabs mounted on the interior edges of the shroud engage the circular opening in the adapter plate. The same tabs are also used to stabilize two or more fans when they are stacked during storage and transport.
