ABSTRACT:
A clip board including a generally rectangular flat board for supportively receiving writing paper or the like thereatop and a pivotally movable paper clamp connected adjacent one end of the board and spaced above the board's writing surface. The paper clamp is pivotally interconnected to the board about a transverse axis parallel to the one end of the board by at least one downwardly extending retaining bracket which is inserted into a mating longitudinal slot in the board and pivotally held thusly by a transverse retainer pin. The retainer pin engages transversely through the lower end of the retaining bracket and extends in either direction beyond the width of the slot to engage against the bottom surface of the board adjacent the slot. A simple generally V-shaped spring acting in compression is positioned between the paper clamp and the board so as to pivotally bias the paper clamp against the board along the paper clamp's paper engaging edge which faces toward the central portion of the board. The paper clamp, in a broad sense, may also include a housing for containing a stack of alternately adhered memo sheets. This invention thus facilitates quick assembly and reduces or eliminates transverse bending or warping of the board during use.
