Abstract
A loose-leaf binder stiffener, which has a body (20) with an integral U-shaped channel portion (28) that grips the upper edge of a binder for holding it in an open and flat position. The channel portion includes an upper leg (32) with a wedge shaped end (36) that is forced between the binders spine (22) and ring holding rigid strip (38). A C-shaped portion (56) of the body (20) holds and stores pens or pencils and a raised upright member (60) adds stiffness. Three embodiments of the upright member (60) include a card holder (62), a beam (68), and a second C-shaped member (56').
Claims20
A spined multi-ring loose-leaf binder stiffener for holding hinged covers of a binder open in a flat, rigid position, comprising:
- a stiffener body having a longitudinal length sufficient to interface with a binder spine and a portion of each cover,
- said body having a springable channel portion including a web, an upper leg and a lower leg, for resistably gripping an upper edge of the binder when forced thereupon, and
- said body further having a raised nonpliant upright member adjoining said channel web, for linear rigidity and structural integrity of the binder stiffener.
A spine stiffener including a body having a longitudinal length sufficient to interface with a portion of the covers hinged to a spine and to hold them open in a flat, rigid position, the stiffener body comprising:
- a springable channel portion including a web, an upper leg and a lower leg, for resistively gripping an upper edge of the covers when forced thereupon;
- a raised nonpliant upright member adjoining said channel web, for linear rigidity and structural integrity of the spine stiffener;
- and
- a receiving portion generally opposite the channel portion relative to the upright member, sized to springably receive writing utensils, permitting storage and accessibility thereof.
