Patent ID: 8641006

Claim:
An apparatus for supporting an airflow hood relative to an airflow register in a first surface and extending between the first surface and a lower surface, the apparatus comprising: a support device operably attached to the airflow hood and configured to support the airflow hood relative to the first surface proximate the register, the support device configured to engage the lower surface spaced away from the first surface; the support device having a top end and a bottom end, the top end coupled to the airflow hood and the bottom end engaging the lower surface, the support device including a biasing device to bias the airflow hood against the first surface, the biasing device comprising: a housing defining a top portion and a bottom portion, the top and bottom portions being axially movable relative to one another and the bottom portion of the housing having a top end and a bottom end; and a biasing structure having a top end coupled to the top portion of the housing and a bottom end coupled proximate the bottom end of the bottom portion of the housing, the biasing structure selectively providing an extension force to the support device for supporting the airflow hood; wherein the apparatus further comprises a frame coupled to the top end of the support device and configured to fit inside the airflow hood and be operably attached thereto, the frame comprising: a base member; an upright member attached at either end of the base member; and a cross member extending between upper regions of the upright member.
