  • Patent number: 4711046
    Abstract: A multi-panel display comprises a plurality of rectangular panels formed of a foam core laminate interconnected at adjacent side edges by flexible plastic strip hinges formed of resilient sheet material and fastened in slots in the adjacent side edges of the panels. The outer edges of the panels include longitudinal slots that extend around the outer periphery of the panel display. The front and back surfaces of the panel display are covered by a loop fastener fabric, with the ends of the fabric on the front and back surfaces extending over the outer edges of the panel display and tucking into the slots around the periphery of the panel display so as to conceal the ends of the fabric. Separate panel display sections can be interconnected by stiff splines that fit in the slots in opposing edges of display sections placed edge-to-edge on top of each other. Panel display sections can be interconnected horizontally by hook fabric strips inserted in the outer side edges of the panel displays.

  • Patent number: 4594829
    Abstract: A joint interlocking system includes T-shaped splines (30) each having arms (32), lips (34) and a center flange (36). The splines (30) are secured within slots (20) formed in the edges of panels (12) or similar articles/members to be interlocked together in various structural configurations. H-shaped connectors (40) each include a cross bracket (42), legs (44) and inwardly directed retaining lips (46). Beads (35) are formed on the ends of the spline lips (34), and project inward toward the associated spline center flange (36). Corresponding beads (48) are formed on the ends of the connector retaining lips (46) and project inwardly toward the associated cross bracket (42). The spline beads (35) can be captured in connector pockets (50) formed by the cross bracket (42), retaining lips (46) and connector beads (48) so as to interlock the splines (30) to the connectors (40).
