ABSTRACT:
The present disclosure relates to the combination of a clipboard, having a clip of plastic material secured to a board. The clip includes a U-shaped one-piece unitary member having first and second sides and a connecting portion interconnecting the two sides. A mounting wall extends laterally outwardly from the first side of the member and has first and second spaced spring retaining grooves. Wall means has rivets extending therethrough to secure the clip to the mounting surface. First and second spaced spring retaining lugs are formed on the second side of the unitary member on the inside surface thereof and a lifting member is formed on the outside surface of the second side of the unitary member to enable the user of the combination to lift the clip to either place paper underneath or to remove paper therefrom. A torsion spring, within the U-shape, has a tongue secured by the spring retaining lugs. The unitary member between the mounting wall and the first side has a thinner section than at other places in the cross section of the generally U-shape so as to permit flexing of the unitary member at this location or position during operation of the clip. The engaging surface of the unitary member in its molded condition and before being attached to the clipboard is located a greater distance from the connecting portion of the U-shape than the mounting wall so that when the clip is secured to the clipboard and the engaging surface and the mounting wall both lie on the same surface, a force is created tending to hold the engaging surface firmly against the mounting surface of the clipboard.
