ABSTRACT:
A rack for a removable shelf comprises a pair of profiled vertical joints with generally U-shaped cross-sections, cross-member braces for linking together the pair of profiled vertical joints to form a unit, and interlinkable longitudinal beams also for connecting together the pair of profiled vertical joints. Two longitudinal rows of slanted apertures are provided along the length of each one of the pair of profiled vertical joints for fitting together the pair of profiled vertical joints with the interlinkable longitudinal beams. The apertures are arranged in pairs equidistant from each other and converge symmetrically together downwards. Each of the apertures has a contour which takes the approximate shape of an irregular pentagon. Angular sections are provided at each end of the interlinkable longitudinal beams for fitting these beams with the pair of profiled vertical joints. A free wing is included as a part of each of the angular sections for jutting out in a plane parallel to the length of each of the pair of profiled vertical joints. A tongue is provided in the free wing for fitting into at least one of the apertures. A safety bolt is formed as a mainly S-shaped shank for interlocking the tongue into at least one of the apertures. The safety bolt has one end branch arranged to extend through the free wing in which the tongue is provided and has the other end branch arranged to extend through at least one of the apertures.
