Claim of US Patent No. 9,907,211

1. An apparatus comprising:
a locking louver assembly, the locking louver assembly comprising:
at least one louver coupled to and disposed at one of an air inlet or an air outlet of an air-moving assembly, the air-moving
assembly being removable from a chassis within which the air-moving assembly resides when in an operational state, and the
at least one louver pivoting between an operational orientation and a quiesced orientation, dependent on presence or absence,
respectively, of airflow through the air-moving assembly; and

a locking mechanism, the locking mechanism comprising:
at least one keying element affixed to the at least one louver to pivot therewith, one keying element of the at least one
keying element being affixed to one louver of the at least one louver at a pivot axis thereof, and comprising an elongated
key extending transverse to the pivot axis, the elongated key being oriented in a first direction when the one louver is in
the operational orientation, and in a second direction when the one louver is in the quiesced orientation; and

at least one key-receiving element associated with the chassis and comprising at least one key opening, one key opening of
the at least one key opening receiving and accommodating movement of the elongated key therein between the first direction
and the second direction, wherein the one key opening of the at least one key opening comprises an inner wall region, and
wherein the air-moving assembly is prevented from being removed from the chassis by the elongated key oriented in the first
direction contacting the inner wall region of the one key opening.
