A rack (1) for stacking and transporting flat components comprises a base (2), support columns (3) extending generally vertically from the base (2), and shelves (5) mounted in the support columns (3) for pivotal movement about horizontal axes and arranged closely one above the other. Each shelf (5) includes a support part (5), for receiving a flat component (15), disposed on one side of the pivot axis (7), and a counterweight (9) and a control arm (8) disposed on the other side of the pivot axis. In use, when a component (14) is placed on the support part (6) of a shelf (5), the latter is moved from an inclined receiving position into a horizontal supporting position, and during such movement the control arm of the shelf cooperates with the control arm of the shelf (5) immediately above to move the upper shelf from a vertical position in which the shelf is retracted between the support columns (3) to the inclined receiving position. To permit a smaller space between the shelves, the support parts (6), the control arms (8), and the counterweights (9) of the respective shelves (5) are arranged in different vertical planes, and to enable locking of the shelves (5) they are further provided with locking arms (10) arranged in a further verticle plane, the planes being spaced in the direction of the pivot axes (7) of the shelves (5).
