Abstract: A sliding and articulating roof rack adapted to be attached to a rack bar of a conventional roof rack that permits easy loading of an article holder attached thereto. A track attached to the rack bar has a sliding member therein permitting an arm to be moved co-axially along the track until extending out over the vehicle. The arm then pivots downward. The arm has an article holder attached thereto. By pivoting the arm downward, an article holder can be easily loaded with articles to be carried on the roof of a vehicle, such as skis or other items. In one embodiment of the present invention, an angularly fixed slide is slid co-axially with a track attached to a rack bar. A movable slide guide or track is then pivoted downward. A slide contained within the movable slide guide or track is then further extended further while in the downward pivoted position. This embodiment greatly facilitates the loading when vehicles are parked close to each other.
