A multi-level rotational shelf structure including top and bottom suspension tubes fastened to the surface of a wall with a plurality of shelves between the suspension tubes. Each shelf is supported on a bushing assembly which enables each shelf to pivot about an axis between the top and bottom suspension tubes independently of the other shelves. An upright tube extends between adjacent shelves acting as a spacer and a mount for the bushing assemblies.

[ What is claimed is:] [1.] A multi-level rotational shelf structure configured to be fastened to a wall surface, and comprising two suspension tubes with a plurality of shelf assemblies fitted between the two suspension tubes, each shelf assembly having a shelf and a lock end component with bushings which fit onto and clasp the shelf, and an upright tube fastened onto the lock end component between adjacent shelves, wherein:a) each shelf engages a recess in a fastening piece and is clamped by a bolt threaded into the fastening piece, at a bottom of the shelf, the fastening piece is connected to a support bar located at the bottom of the shelf, and extending from the support bar is a brace having an end securely fitted with a pivot joint of the lock end component; andb) the lock end component includes a pivot joint threaded rod, including a washer that clasps onto the bushing, one side of the bushing is fixed on the lock end component passes through the pivot joint and is secured in position by a nut screwed onto the end of the threaded rod, an end of the bushing is inserted into one of the suspension tubes and the upright tube, whereby in a middle section, a circular flange structure protrudes allowing ends of the bushings to be slipped into the pivot joint, and wherein the flange circumference equals that of the bushings, so as to form a smooth pivoting tubular structure.
