Sheet support apparatus suitable for mounting sheet material is disclosed. The apparatus is especially useful for displaying information contained on paper or cardboard, or in brochures, etc. The apparatus comprises an elongated, rigid frame including three generally planar and integrally connected wall members spaced to define a cavity therebetween for receiving an edge of sheet material. Anchoring means, such as a leaf spring, are provided which can be inserted and removed from the cavity; the leaf spring cooperates with a shoulder on one wall member to anchor the sheet in the cavity.

Sheet support apparatus, comprising: a. an elongated, rigid frame, said frame including first, second and third wall members, said wall members having generally planar inner and outer wall surfaces, and said wall members being integrally connected and spaced to define an elongated cavity therebetween for receiving an edge of a sheet to be supported, said first wall member being substantially perpendicular to said third wall member and said second wall member meeting said third wall member at an angle of between about 50°and about 80°; b. resilient anchoring means for anchoring a sheet edge within said cavity, said resilient anchoring means comprising a leaf spring having first and second terminal portions, said first terminal portion slanted towards said third wall member thereby making it easier to insert a sheet edge into its anchored position within said frame cavity than to withdraw it therefrom, said leaf spring also having one of its sides in substantially continuous contact with the inside surface of said second wall member and having another of its sides bent inwardly away from the inner surface of said third wall member; and, c. means for retaining said resilient anchoring means within said cavity, said means for retaining comprising an indented slot forming a shoulder located on the inner surface of said first wall member contiguous to where said first wall member joins said third wall member, said shoulder extending longitudinally along said first wall member, and said second terminal portion of said leaf spring designed to cooperate with said shoulder to retain the leaf spring within the frame cavity.
