Abstract: A connection member for connecting boards includes a tubular body having two flanges extending radially outward from an outer surface thereof and the two flanges are located at a distance from two ends of the tubular body. The two ends of the connection member are inserted into holes defined in the boards so as to connect the boards in the longitudinal direction. The connection member may include two parallel tubular bodies so as to connect the boards in the transversal direction.

Abstract: A display rack includes a plurality of boards and each board includes a plurality of holes defined in a top surface and a bottom surface thereof. A plurality of connection members each have two ends which are inserted into the holes in the bottom surface of one board and the holes in the top surface of another board so as to connect the boards in the longitudinal direction. The connection member may include two parallel tubular bodies so as to connect the boards in the transversal direction.

Abstract: A board for a display rack includes a top surface and a bottom surface, and at least one elongate groove is defined in the top surface and the bottom surface, respectively. The elongate groove is defined by ribs with trapezoid-shaped cross section so as to reinforce the structural strength of the board. A plurality of holes are defined in corners of the board so as to be connected with connection members which assemble the boards to be the display rack.
