Ceiling vent diffuser

摘要

A device for altering the airflow pattern from a ceiling vent diffuser by obstructing openings in a region of the diffuser. The device comprises a flexible member that is secured to a diffuser vane by a hook member and two tabs. The hook member has two or more engagement regions which enable it to engage vanes on different manufacturer's diffusers. The first end of the hook member is either pivotally secured to the flexible member or is engaged in an adjustment mechanism thereon. The adjustment mechanism allows the second end of the hook to be situated in different positions relative to an interior edge of the flexible member so as to accommodate different diffusers. An extension detachably engages the flexible member to increase the size thereof to accommodate larger diffusers.

1. A device for altering the airflow pattern from a vent diffuser that includes one or more vanes, an interior surface, an exterior surface and one or more openings through which air flows from the interior surface of the diffuser to the exterior surface thereof said device comprising:
a flexible member having an inner surface and an outer surface; a locking mechanism provided on the inner surface of the flexible member and being adapted to detachably retain the flexible member on the vent diffuser such that the flexible member obstructs at least one opening in a region of the vent diffuser and thereby substantially prevents airflow from that obstructed region; and wherein the locking mechanism includes: a hook member having a first end adjacent the inner surface of the flexible member and a second end remote therefrom; and wherein the hook member extends outwardly from the inner surface and wherein the second end of the hook member extends toward the inner surface of the flexible member and includes a first engagement region and a second engagement region, and wherein the second end of the hook member is adapted to engage one of the vanes of the vent diffuser in one of the first engagement region and the second engagement region; and an adjustment mechanism provided on the inner surface of the flexible member; wherein the adjustment mechanism defines a channel therein which extends for a distance along the inner surface of the flexible member and the channel has a length and a width and wherein the first end of the hook member is engaged in the channel of the adjustment mechanism and is selectively movable along the length of the channel and across the inner surface of the flexible member between a first position and a second position; and, when the first end of the hook member is in the first position, the second end of the hook member is disposed in a first location set at a first distance relative to the inner surface of the flexible member; and when the first end of the hook member is in the second position, the second end of the hook member is disposed in a second location set at a second distance relative to the inner surface of the flexible member.
