| description | Elongated rigid leg members are pivotally connected to one another at their ends and provided with oppositely facing magnetic elements for clamping opposite sides of a sheet of paper or the like. Two center members may be hinged together at one end with an additional member pivoted to the other end of each of the two center members to permit folding about mutually perpendicular axes. The device is used primarily to clamp open large documents such as blueprints and the like that are normally stored in a rolled condition. The members are placed in opposing parallel relationship on either side of the document and extended along the document length so that the magnetic members will coact to clamp the document in a flat, open condition. |
