Adjustable height fairing with translatable upper fairing member

摘要

A multi-piece nestable fairing (20) for mounting on the roof (22) of a vehicle (24) is disclosed. The fairing (20) has lower and upper fairing members (26,28). The lower fairing member (26) is mountable to the roof (22) of the vehicle (24). The upper fairing member (28) is selectively translatable relative to and affixable to the lower fairing member (26) between a lowered nested position and a raised operative position thereby altering the overall height of the fairing (20). The lower fairing member (26) preferably has a support (44) configured therein so that the upper fairing member (28) may rest upon the support (44) with the upper fairing member (28) being affixable to the lower fairing member (26) in the raised operative position. Preferably, the upper fairing member (28) has a set of spaced openings (62) which are selectively alignable with lower and upper sets of spaced apertures (48,50) in the lower fairing member (26) so that the upper fairing (28) may be affixed in either the lowered nested position or in the upper raised position.
