Abstract: A rack arrangement for supporting a load, for example above the roof of a vehicle body, comprises a pair of substantially parallel elongate guide members 3 each having a lower upwardly extending portion 3a and an upper load supporting portion 3b. A load carrier member 4 is rockably connected to the guide members and is manually slidable from a lowered position upwardly along the lower guide member portions 3a onto the supporting portions 3b to a load storage position. Means is provided for releasably retaining the carrier member in the load storage position, for example a cup-like recess 17 which locates the base of a handle 12 for the carrier member.
