Abstract
Abstract A device for organizing papers, files and the like for use in a business environment or other similar situations has a base on which one or more tilt plates are located. The tilt plates are capable of being oriented with respect to the base in a tilting mode and in a locked mode. In the tilting mode the tilt plates rotate about a bottom edge to tilt forward and backward. In the locked mode, the tilt plates are fixed in a set orientation with respect to the base. The tilt plates are easily shifted between the tilt mode and the locked mode by simply sliding them sideways a short distance on the base. Tabs on the bottom of the tilt plate maintain the tilt plate on the base and interact with a stop and lock member on the base to determine which of the modes the tilt plate is in.
