Abstract A self-supporting foldable support structure comprises a vertical standard having a main panel and a pair of stiffener ribs extending longitudinally in planes generally normal to the plane of the vertical standard and in the nature of an easel. Structure is provided for causing the stiffener ribs to move to stiffening position in the nature of a platform for the display of articles in front of the vertical standard. Said structure comprises a front wall spaced from the vertical standard with a foldable wall extending from each end of the front wall and toward the vertical standard. Each foldable wall consists of hingedly connected wall portions, one of same being secured to a correlative stiffener rib and the other being hingedly connected to a correlative end of the front wall. The platform panel is hingedly connected to the front wall, and resilient means are connected between the platform panel and the vertical standard and are arranged to bias the platform panel to a position resting upon the tops of the foldable walls and tending to straighten the line of fold between the wall portions and thereby move the stiffener ribs to stiffening position.
In a self-supporting foldable support structure adapted to be vertically free standing: a. a vertical standard having a main panel and a pair of stiffener ribs extending longitudinally thereof in planes generally normal to the plane of said main panel; b. structure for causing said stiffener ribs to move to stiffening position and for providing a platform for the display of articles in front of said vertical standard comprising: i. a front wall spaced from said vertical standard; ii. a foldable wall extending from each end of said front wall toward said vertical standard; iii. said foldable wall comprising hingedly connected wall portions; A. one of said wall portions being secured to a correlative stiffener rib, and B. the other of said wall portions being hingedly connected to a correlative end of said front wall; iv. a platform panel hingedly connected to said front wall; v. resilient means connected between said platform panel and said vertical standard and biasing said platform panel to a position resting upon the tops of said foldable walls and tending to flatten the angle between said wall portions and to move said stiffener ribs to stiffening position.
