  • Clip-frame type device for displaying a document
    Patent number: 4805325
    Abstract: The device is of the clip-frame type designed to display a document in the form of a text or picture. It comprises spring clips designed to hold the edge of the document against a rigid plane support by means of claws. Each clip is rivetted to the support and the claw on each clip is at the end of a curved branch incorporating a lever. The curvature and elasticity of this branch tend to hold the claw against the document or an optional piece of glass over it. When the lever is depressed the clip "opens" and the claw moves back to enable a document to be inserted or removed.
