  • Patent number: 5551178
    Abstract: A collapsible sign includes a flexible banner supported by a collapsible stand. The collapsible stand, of A-frame configuration, includes two pairs of legs at each end of a cross-member, the apex of each leg pair and cross-member end retained in a unique one-piece connector. Each connector has two leg cups and a cross-member cup attached to a base block by a living hinge. A latch and saddle releasably secure the cross-member cup to the base block in the erected position. A cammed key and keyway releasably lock the leg cups to one another in the erected position. There is a slight interference fit between the cups which assists securing them in the erected position. In breaking down the sign, each leg pivots toward its paired partner upon release of the key from the keyway and the cross-member likewise pivots toward the legs upon release of the latch resulting in all legs and the cross-member being generally parallel to one another in the collapsed position.
