  • Patent number: 4730739
    Abstract: An open framework merchandise display system consists of triangular trusses joined by junction plates and junction flanges. Three rods protrude from one side of each junction plate and into the hollow longitudinal tubes of the truss. A post with a square cross section protrudes from the other side of the junction plate and fits between horizontal parallel plates of the junction flange.The flange plates have an octagonal system of pins and bolt holes, which fit against matching slots and holes in the posts, allowing the horizontal trusses to join the flange at 45 degree increments. A similar set of vertical plates is welded to the top and bottom of the flange, allowing vertical trusses to join the flange as well.The tubes of each truss are joined by "Z" shaped cross members, allowing display from the truss itself. The cross section of each truss is an isosceles triangle formed by inscribing same within a square, allowing shelves to be attached at 90 degree increments.
