  • Patent number: 5058850
    Abstract: The easel is a flat, generally diamond-shaped member formed of non-scratching stiff, resilient material, such as plastic. The member has a line of weakness extending thereacross between its opposed oblique angle points. The member can therefore easily be bent along the line of weakness to adopt a two-sided pyramidal form having rearwardly inclined, load-supporting edges and bottom edges. Means are provided along the load-supporting edges for disengageably supporting and frictionally interlocking with a picture frame or flat sheet to be displayed in spaced, non-scratching arrangement above a flat support surface, such as a table top. In the case of a channel-type picture frame, the means may comprise opposed L-shaped slots extending inwardly from each load-supporting edge a short distance above the bottom edge. The L-shaped slots form a T-shaped member. The T-shaped member can frictionally interlock with the base channel of a picture frame, to suspend the frame in a rearwardly inclined display position.

  • Patent number: 4886231
    Abstract: A portable bookstand is formed from a sheet of rigid card with transverse hinge lines dividing the card into a number of panels to form a base panel, an upstanding front panel, a rearwardly inclined edge receiving panel, an upwardly inclined book face receiving panel and a rearward support structure. Hook and loop fasteners are provided toconnect the junction line between the inclined panels to the base panel and to adjustably position the support panel structure to provide different inclinations of the book receiving panel. The device can be folded flat by lifting the inclined panels away from the base panel to allow the support panel to fold in between.
