Summary of the Invention
A clip-on identifier means is provided for a loose-leaf ledger book of the type having a front binder bar with a front cover pivotally attached to the binder bar. The identifier means includes a middle portion spanning a front side of the front binder bar with inner and outer edge portions engaging inner and outer edges, respectively, of the front binder bar. The outer edge portion of the identifier means includes an integral magnifying lens for magnifying an identifying label oriented for viewing at the outer edge of the front binder bar.
A retaining strip extends from the outer edge portion of the clip-on identifier means, and said retaining strip engages a back side of the front binder bar of the ledger book. The middle portion and inner edge portion comprise a transparent flexible sheet formed to closely engage the front side and inner edge of the front binder bar.
The outer edge portion of the identifier means, which includes the magnifying lens, includes an inner surface constructed for close engagement with the outer edge of the front binder bar. The identifier means may be installed upon the front binder bar of the ledger book by placing the retaining strip in engagement with the back side of the front binder, then inserting the inner edge portion of the identifier means through a space between the inner edge of the front binder bar and a hinge connecting the front binder bar to the front cover and snapping the inner edge portion over the inner edge of the front binder bar to lock the same in place thereon.

Detailed Description of the Preferred Embodiments
Referring now to the drawings, and particularly to FIG. 1, a loose-leaf ledger book, as used with the present invention, is shown and generally designated by the numeral 10.
Ledger book 10 includes a back binder bar 12 having a back cover 14 pivotally attached thereto by a back hinge 16. First and second loose leaf sheet receiving posts 18 and 20 extend upward from back binder bar 12 and are received in holes 22 and 24 of a front binder bar 26. A plurality of loose leaf pages 27 are located on the posts 18 and 20 between front and back binder bars 26 and 12. Front binder bar 26 includes first and second release buttons 28 and 30 for releasing first and second posts 18 and 20, respectively, from engagement with front binder bar 26.
A front cover 32 is pivotally attached to front binder bar 26 by a front hinge 34. As is best seen in FIG. 3, the front binder bar 26 includes flat top and bottom sides 36 and 38, respectively, and rounded inner and outer edges 40 and 42, respectively, joining the top and bottom sides 36 and 38. Although the cross-sectional view of the front binder bar 26 is shown in FIG. 3 as being of solid construction, the front binder bar 26 is typically of hollow construction and includes mechanisms (not shown) connected between release buttons 28 and 30 and posts 18 and 20.
As is best seen in FIG. 2, the front hinge 34 is spaced from inner edge 40 of top binder bar 26 so as to define a space 44 therebetween.
The ledger book 10 and the various components of the ledger book 10 described up to this point are all old in the art and may be found in a ledger book such as the Boorum & Pease Model No. 6215 1/2B previously mentioned.
The clip-on identifier means of the present invention is shown and generally designated in FIGS. 1-4 by the numeral 100. Clip-on identifier means 100 includes a transparent flat middle portion 102 extending across flat front side 36 of front binder bar 26. Extending from middle portion 102 are first and second transparent edge portions 104 and 106, respectively.
First edge portion 104 includes a round surface 110 for closely engaging rounded inner edge 40 of front binder bar 26.
Second edge portion 106 includes a magnifying lens means 112 for magnifying an identifying label 114, said identifying label 114 being oriented for viewing at said outer edge 42 of front binder bar 26. Magnifying lens means 112 is integrally formed with the remainder of clip-on identifier means 100.
Second edge portion 106 of identifier means 100 includes a rounded surface 116 which fits around and closely engages rounded outer edge 42 of front binder bar 26.
Located on inner surfaces 110 and 116 are first and second raised longitudinally extending ridges 118 and 122, respectively. Ridges 118 and 122 hold middle portion 102 and outer edge portion 106 of identifier means 100 slightly spaced from front binder bar 26 so that identifying label 114 may be received therebetween. Ridges 118 and 122 may be described as a means for receiving identifying label 114 so that the label is viewable through middle portion 102 and outer edge portion 106. As is shown in FIG. 1, identifying label 114 includes a first indicia, "GMC OIL & GAS CORP.", viewable through middle portion 102, and a second indicia "GMC OIL & GAS" viewable through magnifying lens 112 of outer edge portion 106.
The ridges 118 and 122 could be replaced by label receiving grooves (not shown) formed in the inner surfaces of middle portion 102 and outer edge portion 106.
It will be understood that the rounded inner surface 116 of outer edge portion 106 may be described as "closely engaging" outer edge 42, even though there may be a slight clearance therebetween for receiving label 114. By "closely engaging" it is meant that surface 116 fits closely around edge 42 even though surface 116 may not actually touch edge 42.
Extending from second edge portion 106 is a retaining strip 120 which provides a means for engaging flat backside 38 of front binder bar 26.
Identifying label 114 is shown in FIGS. 1 and 4. The identifying label is not shown in FIGS. 2 and 3, so that the other details of identifier means 100 may be more clearly shown.
The identifier means 100 may generally be described as being a clip-on identifier means which is detachably attached to front binder bar 26. The identifier means 100 is retained in place upon front binder bar 26 by the inner and outer edge portions 104 and 106, in the following manner.
Middle portion 102 and inner edge portion 104 comprise a relatively flexible transparent sheet of material formed in a shape to closely engage top side 36 and inner edge 40 of front binder bar 26.
The outer edge portion 106, which is integrally formed with the remainder of identifier means 100, includes the magnifying lens 112 and is therefore relatively thicker and less flexible than the other portions of identifier means 100.
The retaining strip 120 extending from outer edge portion 106 has a thickness about equal to that of middle portion 102.
The clip-on identifier means 100 is attached to front binder bar 26 in the following manner. The retaining strip 120 is placed in engagement with flat back side 38 of front binder bar 26, and is in effect sandwiched between the uppermost one of loose leaf sheets 27 and the flat back side 38 of front binder bar 26. The curved surface 116 of outer edge portion 106 is placed about the rounded outer edge 42 of front binder bar 26. The middle portion 102 is then laid across flat top side 36 and the inner edge portion 104 is inserted through space 44 between binder bar 26 and front hinge 34 and is snapped over inner edge 40 of binder bar 26 so that surface 110 of inner edge portion 104 engages rounded inner edge 40 of front binder bar 26.
The clip-on identifier means 100 may also be constructed with a retaining strip (not shown) extending from inner edge portion 104.
Due to the presence of integral magnifying lens 112 of outer edge portion 106, the identifying label 114 is magnified so as to enlarge the appearance thereof as illustrated in FIG. 4. In FIG. 4 the right hand portion of magnifying lens 112 has been cut away so as to show a side by side comparison of the unmagnified identifying label 114, as seen on the right-hand side of FIG. 4, as compared to the magnified image thereof as shown in the left-hand side of FIG. 4.
The clip-on identifier means 100 could of course, be attached to back binder bar 12 instead of front binder bar 26.
Thus, the ledger book with clip-on identifier means of the present invention is well adapted to attain the ends and advantages mentioned as well as those inherent therein. While presently preferred embodiments of the invention have been described for the purpose of this disclosure, numerous changes in the construction and arrangement of the parts can be made by those skilled in the art, which changes are encompassed within the spirit of this invention as defined by the appended claims.
