US Patent 6929542 Air flow deflector

Air deflector for deflecting an air flow from an air register including a pair of mounting members adapted to be mounted on opposite sides of a venting member of the air register device and a laterally expandable guide member arranged between the mounting members. The guide member is expandable to different lengths to thereby enable the length between the mounting members to vary and allow the air deflector to be used for different sized air registers. The guide member is pivotally connected to the mounting members and pivotable into different angular positions relative to the mounting members to thereby enable the air flow to be deflected into different directions depending on the angular position of the guide member.
