Abstract: A telescoping roof basket assembly (10) for attachment to a roof (12) of a vehicle (14) is provided. The basket assembly (10) includes a pair of rails (18) fixedly coupled to the roof (12) of the vehicle (14). Each rail (18) defines a primary channel (22) and a secondary channel (24). Furthermore, each primary channel (22) has an extension bar (26) slidably positioned therein for telescopically fitting the extension bar (26) to the rail (18). The extension bars (26) are capable of extending rearwardly from the rails (18). Moreover, these extension bars (26) are pivotally coupled to a front end portion of a moveable basket member (30). This moveable basket member (30) has a rear end portion with a pair of tabs (44) extending therefrom. These tabs (44) are intended for insertion into the secondary channels (24) and securing the moveable basket member (30) to the rails (18). The telescoping roof basket assembly (10) is moveable between a roof mounted position and a back end mounted position.
