<p>An extremely strong yet lightweight and easy-to-assembly roof rack for motor vehicles is realized using extruded aluminum tubing to create side members and crossbars for joining the side members to one another across the width dimension of the vehicle roof. Each side member comprises a pair of elongated rails that are clamped together by a series of clamps that cooperate with attachment spines integrally formed with the rails. Attachment flanges forming a part of the extrusion on one rail on each side member facilitates attachment of the crossbar members thereto. Several ways of affixing the rack structure to the roof of the vehicle are also discussed.</p> |
