The shelf consists of links (01), having horizontal openings for the insertion of laths (02 and 04), shown on Fig. 1 and 2, the horizontal laths (03) are during assembly inserted under the angle alpha and after the vertical laths (02 and 04) are inserted, the horizontal laths (03) are put into horizontal position, which wedges the tooth of link (01) to the grooves of horizontal laths (03), as shown on details "A-B", Fig. 4. Since dimension X is larger than dimension X-02, Fig. 3, during insertion of horizontal lath (03) into horizontal position a prestress is generated, helping to improve the rigidity of the whole shelf. An even larger rigidity is achieved by champs (05) mounted into the vertical openings of each link (01) and finishing link (01) with clamp (06), Fig. 5 and 6. The shelf can be extended in vertical and horizontal direction if required, it is easily assembled and disassembled and since the link (01) is of plastics and the horizontal and vertical laths are wooden the shelf is very cheap.
