Binding system using binder pieces with concentric cylinders

摘要

A binding system for binding a set of media sheets, including first and second binder pieces, each including an end cap, a retainer, a cylinder and a connection mechanism. The retainer has an arc-shaped cross-section having an associated arc angle thereby providing an opening slot that extends along a length of the retainer. The retainer and the cylinder are connected to the end cap such that the cylinder is positioned within the retainer. The binder pieces are adapted to bind the set of sheets of media by inserting the set of media sheets into the first and second binder pieces such that the media sheets are wrapped around the cylinders and extend out of the opening slots in the retainers, and engaging the connection mechanisms to connect the first and second binder pieces together.

1. A binding system for binding a set of media sheets, comprising:
first and second binder pieces, each including:
an end cap;a retainer having an arc-shaped cross-section, the arc-shaped cross-section having an inner diameter and an associated arc angle of at least 200 degrees and less than 360 degrees thereby providing an opening slot that extends along a length of the retainer, wherein one end of the retainer is connected to the end cap;a cylinder having an outer diameter and a length, the outer diameter of the cylinder being less than the inner diameter of the arc-shaped cross-section of the retainer, wherein one end of the cylinder is connected to the end cap such that the cylinder is positioned within the retainer; anda connection mechanism positioned on an end of the retainer or the cylinder opposite to the end connected to the end cap; wherein the first and second binder pieces are adapted to bind the set of sheets of media by;
inserting a first edge of the set of media sheets into a gap between the retainer and the cylinder of the first binder piece such that the media sheets are wrapped around the cylinder with the media sheets extending out of the opening slot in the retainer;inserting a second edge of the set of media sheets into a gap between the retainer and the cylinder of the second binder piece such that the media sheets are wrapped around the cylinder with the media sheets extending out of the opening slot in the retainer, the second edge of the media sheets being opposite to the first edge of the media sheets; andengaging the connection mechanism on the first binder piece with the connection mechanism on the second binder piece to connect the first and second binder pieces together.
