Abstract:
1. A pallet, comprising a base board and secondary boards movably coupled to corners of the base board, coupling axles being arranged between the base board and the secondary boards so that the secondary boards define an article bearing surface, the coupling axles each comprising a base and an extension section extending from the base, the extension section forming a plurality of flexible engagement keys close to an end thereof adjacent to the base, the base board forming receiving sections respectively corresponding to the bases and track channels respectively corresponding to the extension sections, the track channels each forming therein a plurality of groups of retention slots corresponding to the flexible engagement keys, the bases of the coupling axles being respectively received in the receiving sections of the base board in such a way that the extension sections of the coupling axles are movable in the track channels to allow the engagement keys to be selectively receivable in and retained by the retention slots of one of the groups so as to retain the coupling axles in the base boards, the extension sections having free ends respectively fixed in the secondary boards to movably couple the secondary boards to the base board, wherein each of the coupling axles is of an axisymmetric configuration with the flexible engagement keys being distributed along a circumference of the axle in an equally-spaced manner, each of the engagement keys having a triangular configuration comprising a slope edge facing a predetermined direction in which the extension section is movable and a straight edge facing a direction opposite to the predetermined direction to an axis of the extension section for effecting enhanced positioning of the extension section in said opposite direction.
