Abstract
The clamping clip construction of a clip board is improved by changing the clamping member to provide an offset flange formed with a shelf-like tray at the end, thereby to shorten the clip and enlarging the available space on the board, and shortening the distance to the pivot axis to increase the clamping force, and to provide an enlarged paper engaging surface to safeguard the papers on the board. Retention means are also provided which, together with the tray, form a snap-in detent so that elongated objects such as pens and pencils may be stored and retrieved directly on the clip construction of the clip board.
