A cradle 10 (Fig. 2) for supporting tall unstable articles or dimensionally unstable ones, such as books, comprises a pair of base parts from which extend upstanding, and conveniently upright, members 11, 12 and forming sub-units 16, 17. Each base part has an integral extending base limb 19, 21 which operatively extends to, and rest upon, a surface portion 23 of the cooperating base part of the other sub-unit so that the limbs extending side by side form at least a portion of the cradle base. The lower tip 22 of each limb and upper surface portion 23 have engaging projections and recesses which enable the distance between upstanding members to be defined and prevent separation of sub-units by lateral forces of a supported article bearing on the upstanding members. The weight of the article maintains the interengagement of projections with recesses. The base may extend outwardly to increase lateral support (Fig. 3) and a cradle with more than two sub-units may be formed (Fig. 8) or a wider cradle with additional base parts intermediate the sub-units (Fig. 9). <IMAGE> |
