Abstract: A quick release mount for mounting a fan to a static structure includes a handle for moving a movable member between a locking position and a non-locking position. The handle being operable to move the moving member into and out of an opening in the fan such that the fan can be removed from the quick release mount by moving the handle and moving member to the non-locking position. Some embodiments do not require any tools for removal of the fan and allows the mount to be locked at a predetermined angle relative to the static structure. The other embodiment only requires simple tools. Thus, once the fan is reattached, it need not be readjusted to return to its desired angled position.
