发明名称 Clipboard with dual clamping members
摘要 A clipboard comprising a pair of clamping members arranged substantially parallel one above the other and connected to each other via an intermediate connecting member having a spring loaded hinge connection at each of its elongated ends for securely clamping articles, such as paper sheets, between one of the two clamping members and a board. The lower clamping member is used to hold an existing bundle of paper sheets on the board while disengaging the upper clamping member to add extra paper sheets to said existing bundle of paper sheets. The clamping members are positioned substantially parallel to each other and the lower clamping member extends through a slot formed at the center of a back portion of the first clamping member.
