Abstract
A cam holder system is described. A cam mechanism allows the holder to accept sheet material and be closed easily, while still maintaining strong holding power. The holder is formed by two or more separate pieces of extruded rigid material that slide together. End caps can be used to hold the pieces in alignment with each other so that they do not slide apart when the holder is opened. The cam is located near the middle of the assembly so that the user has leverage when opening and closing the holder. The holder can be squeezed in one direction to open the holder, and in the other direction to close the holder. A lever arm for closure is located above the cam, and a lever arm for opening is located below the cam. The receiving slot is located on-center so that the holder and the sheet material remain aligned with each other during use.
