ABSTRACT:
A cam action fastener for holding together two parts having holes formed therethrough by inserting the fastener through the holes from one side only of one of the parts. The fastener is formed from a single, elongate member having two outer portions equal in length and an intermediate portion having a length substantially shorter than the length of the two outer portions and connecting them together. The fastener is adaptable to be articulated into a doubled over shape having two unequal lengths of a single diameter for fitting through the holes of the two parts.
The fastener is pressed against the outermost part in a manner that causes the unequal lengths to diverge outwardly from each other by cam action rotation of the intermediate portion of the fastener to a point where the two outer portions are spaced a distance from each other equal to the length of the intermediate portion of the fastener.
The fastener is adaptable to be removed from the parts by pulling outwardly on one of the two outer portions which causes the intermediate portion to collapse, break the toggle lock, reverse the cam action rotation and form two unequal lengths having a single cross sectional shape to facilitate removal of the fastener from the openings of the two parts.
