  • Publication number: 20150052792
    Abstract: A notebook labeling system that includes a variety of mounts to detachably attach a label to a notebook. The label includes an indicia surface that forms a visible, external display of indicia along a longitudinal axis of a notebook binder. The indicia identify and categorize the notebook. The label includes a mounting surface that utilizes an adhesive, clasps, and an elastic cord to attach the label to the notebook. The adhesive adheres to a pair of covers on the notebook for mounting the label to the notebook. The clasp pivots to a clamped position to form a tight clamp on the pair of covers or the binder. The clamp secures the label to the notebook. The elastic cord wraps around the cover to mount the label to the notebook. The label is viewable from an upright position, a flat position, or when multiple notebooks are stacked.

  • Patent number: 8287205
    Abstract: A helical plastic coil is used for binding a collated book having a stack of pages with aligned holes along one edge of the book where a leading end of the filament is fed into a first hole at a first end of the book and the coil is rotated about its axis such that the leading end is threaded through the holes by entering each of the holes until the coil is threaded through all of the holes. The leading end of the coil is sheared by an anvil and blade so as to define a leading apex and a leading surface inclined rearwardly from the leading apex along the filament and across the filament. The leading apex is arranged such that, as the leading end enters each of the holes in turn, the leading apex is located on the leading end of the filament at a position thereon facing away from the trailing end of the coil and spaced from the end of the hole facing the first end of the book.

Only selected ones of these modules are combined together and packaged along with a plastic spine protectors, front and back covers, and posts. The spine protector and posts are selected from a plurality of different spine protectors and posts so that they correspond in width to the combined thickness of the individual modules. These can all be boxed in a rectangular-shaped box that is easily stacked in a book store. Thus, a professor who is only interested in teaching a course relating to three topics can have a course book prepared which only includes those three modules. Another professor who wants five different topics to be taught in his course can have a course book uniquely prepared with only those five modules.

  • Patent number: 4907905
    Abstract: A notebook adapted for replacement of leaves has a helical binding coil disposed along a coil axis; a first cover leaf defining apertures along a binding edge; a second cover leaf defining apertures along a binding edge adjacent the binding edge of the first cover leaf; multiple leaves having coinciding apertures along associated edges, the spacing between apertures of the first and second cover leaves and the multiple leaves corresponding generally to spacing between turns of the coil; and an elongated handle element associated with one end of the coil and extending transverse to the coil axis. The handle element is adapted for rotation about the coil axis to advance the binding coil along the axis for engaging and disengaging the coil in apertures of the leaves. The handle may be secured to a cover leaf with the binding coil engaged in the apertures.

  • Patent number: 4136981
    Abstract: A loose leaf binder having a supporting base or lower cover member and a top cover member interconnected by post assemblies receiving a plurality of paper sheets together with a bar mounted on the post assemblies for longitudinal movement thereon with the bar being retained in adjusted position by magnetic attraction between the bar and post assemblies. Each of the post assemblies are constructed of a rigid member and a flexible member which are telescopically arranged and constructed to enable angular orientation of the telescoping components of the post assemblies.
