  • Easel hinge
    Patent number: 4878266
    Abstract: An easel hinge made of a sheet of material having an outer portion with two leg sections joined by a hinge support section. A central portion of the sheet is disposed between the leg sections and interconnected with the hinge support section by bendable hinge elements. Two straddle elements are provided, with each straddle element being spaced from the hinge support section and interconnecting a corresponding leg section with the central portion of the sheet. The sheet includes mounting holes for securing the outer portion of the sheet to one panel of an easel, and the central portion of the sheet to the other panel of the easel, so that the straddle elements limit the angular movement of the easel panels relative to each other.
