Holder for box-shaped articles of different sizes

A holder or rack (1) for storing and displaying a plurality of flat box-shaped articles (7, 8), in a substantially vertical and mutual parallel arrangement, said holder or rack comprising at least an upper rigid beam and at least one lower rigid beam, said upper rigid beam and said at least one lower rigid beams extending mutual parallel in a lateral direction spaced from each other in a vertical direction by at least one rigid spacer member, the upper rigid beam having a downward extending flange portion providing an upper abutment stop for the articles and the at least one lower rigid beam having an upward extending flange portion providing a lower abutment stop for the articles, each of said beams having on a front side thereof, a substantially horizontal and laterally extending projection defining a vertical gap between the projection on the upper rigid beam and the projection on the at least one lower rigid beam, at least the horizontal projection on the at least one lower rigid beam having a substantially smooth and planar horizontal top surface defining a support ledge for a lower corner of a vertically oriented flat box-shaped article and at least the horizontal projection on the upper rigid beam having an underside provided with a laterally extending groove configured to receive and retain an elongated rubber-elastic member having, in cross section, a wedge-shaped lip portion projecting substantially vertical downwards from the underside of said upper horizontal projection when inserted and retained in said groove so as to form a grip or barb retaining an upper corner of a vertically oriented flat box-shaped article pushed into the gap defined between the horizontal projections on the upper rigid beam and the at least one lower rigid beam, wherein said at least one rigid spacer member is provided with means for adjusting the vertical distance between the horizontal projections on the upper rigid beam and the at least one lower rigid beam so as to adapt the gap between said upper and lower projections to a particular vertical size corresponding to a vertical size of the plurality of flat box-shaped articles to be stored in said holder or rack.
