Description:
BACKGROUND OF THE INVENTION
It is common practice for typists and accountants to use a copyholder having a supporting member for holding a printed page and a line guide to assist them in following printed matter line by line. Three such copyholder devices are disclosed in U.S. Pat. Nos. 3,081,739; 3,089,464; and 3,153,400, all of which issued to I. J. Mendels. The disadvantage to all known copyholder devices, including those disclosed in the Mendels patents, is that they can only be used with a single sheet. Consequently in those situations where the sheets are in a ring binder, they must be individually removed and later replaced.
This invention overcomes the above described disadvantage by providing a line guide device that can be inserted into a ring binder without the necessity of opening the rings.
SUMMARY OF THE INVENTION
A line guide device comprising a flat sheet of flexible transparent material with fastening means on one of its side margins for quickly attaching the transparent sheet in a ring binder, and a line guide bar having a magnet member secured at one end that is magnetically attracted to a metallic strip attached to the other side margin of the transparent sheet to hold the line guide bar in a line guide position as it is shifted up and down the transparent sheet. A guide slot is formed along the one side margin of the transparent sheet to hold the outer end of the line guide bar in sliding engagement with the line guide bar in sliding engagement with the transparent sheet.
DESCRIPTION OF DRAWING
For a better understanding of this invention reference may be made to the accompanying drawing, in which:
FIG. 1 is a top plan view of my invention inserted into a ring binder;
FIG. 2 is an end view of my invention taken along the line 2--2 of FIG. 1;
FIG. 3 is a perspective view of the line guide bar and associated magnet member;
FIG. 4 is a partial perspective view of the flexible transparent sheet and associated metallic strip attached on its one side margin; and
FIG. 5 is a partial top plan view similar to FIG. 1, except the flexible transparent sheet has been flipped over to the other side of the ring binder.
DESCRIPTION OF PREFERRED EMBODIMENT
Referring to FIG. 1, there is shown a conventional ring binder 10 in the open book position. Ring binder 10 has three spaced rings 12 which can be opened to insert or remove loose leaf paper 14.
A line guide device 16 embodying the principles of my invention is shown inserted on the left side of ring binder 10. A flat sheet of flexible transparent material of a size at least as large as the loose leaf paper 14 overlays the printed page on the left side of binder 10, and a line guide bar 20 is disposed across the flexible transparent sheet 18 and can be slidably repositioned up or down the sheet to follow the printed matter on the page beneath the line guide bar 20.
An elongated metallic strip 22 is attached along one side margin of transparent sheet 18 in a generally perpendicular relation thereto. The means for mounting the metallic strip 22 comprises an integral upturned flange portion 24 which is folded lengthwise at its approximate midlength to present two folded sections 26, 28 in general parallel relation. The metallic strip 22 is inserted through one of the end openings 30, and a fastener means is provided to hold the metallic strip 22 between the folded sections. One suitable fastener means could be eyelets 32 inserted through the folded sections 26, 28 at their ends and disposed outwardly of right-angled cut-out 34 formed at the opposite ends of metallic strip 22. Another suitable fastener means would be to heat seal the folded sections 26, 28 together to envelope the metallic strip.
A magnetic member 36 is secured to one end of line guide bar 20 in a generally perpendicular relation for holding the line guide bar at different positions by its magnetic attraction to metallic strip 22. Magnetic member 32 comprises a casing 38 having a base portion 40 and a recess 42 formed in an upstanding leg portion 44. A magnet is mounted in recess 42 as by cement 46, and the base portion is fastened to one end of line guide bar 20 by means of rivets 48. The line guide bar and associated magnet member are not new per se and are disclosed in all of the above identified Mendels patents. What is new and novel is the cooperation between the line guide bar 20 and transparent sheet 18.
For clear reading of the printed matter it is essential that the transparent sheet 18 lie flat on the printed page 14. When the thickness of the pages on the left side of the ring binder 10 is less than the width of folded sections 26, 28, it will be appreciated that the flange portion 24 must be positioned upwardly, as depicted in FIGS. 1 and 2 to permit sheet 18 to lie flat on page 14. In this orientation, the line guide bar 18 lies between the printed page 14 and transparent sheet causing some resistance to proper repositioning of the line guide bar. This resistance is substantially reduced by providing a line guide means 50 along the inner marginal edge of the transparent sheet 18.
Line guide means 50 comprises an integral flange portion 52 bent inwardly toward transparent sheet 18 into a generally parallel relation thereto. The inner marginal portion of surface 54 and flange portion 52 present an elongated guide slot 58 into which the outer end 60 of line guide bar 20 is disposed.
To provide quick attachment onto the rings 12, a fastener means 62 is provided at the inner marginal side of transparent sheet 18. Fastener means 62 takes the form of a plurality of T-shaped slots 64 extending inwardly of the inner marginal edge and flange portion 50. In the embodiment shown, the T-shaped slots are spaced to accommodate either a three-ring or two-ring standard binder. It is noted that the length of line guide bar 20 is selected so that its outer end 60 extends into guide slot 58 but would not intersect any of the T-slots 62.
By virtue of the hooking engagement of T-shaped guide slots 62 with rings 12 and the retaining action of guide slot 58 on the outer end of line guide bar 20, it is possible to flip the line guide device 16 from the left side (FIG. 1) to the right side (FIG. 5) of ring binder 10 or vice versa. When the user is done with both pages, the T-shaped slots 62 permit the line guide device 16 to be quickly removed without the necessity of opening the rings 12.
Although a number of materials could be used to form transparent sheet 18, the preferred material is a non-glare vinyl because of its durability and flexibility. Non-glare vinyls have been found very satisfactory in forming the two integral flange portions 24 and 50.
While there has been shown and described a preferred embodiment of the present invention, it will be understood by those skilled in the art that various arrangements and modifications may be made therein without departing from the spirit and scope of the invention.
It is common practice for typists and accountants to use a copyholder having a supporting member for holding a printed page and a line guide to assist them in following printed matter line by line. Three such copyholder devices are disclosed in U.S. Pat. Nos. 3,081,739; 3,089,464; and 3,153,400, all of which issued to I. J. Mendels. The disadvantage to all known copyholder devices, including those disclosed in the Mendels patents, is that they can only be used with a single sheet. Consequently in those situations where the sheets are in a ring binder, they must be individually removed and later replaced.
This invention overcomes the above described disadvantage by providing a line guide device that can be inserted into a ring binder without the necessity of opening the rings.
SUMMARY OF THE INVENTION
A line guide device comprising a flat sheet of flexible transparent material with fastening means on one of its side margins for quickly attaching the transparent sheet in a ring binder, and a line guide bar having a magnet member secured at one end that is magnetically attracted to a metallic strip attached to the other side margin of the transparent sheet to hold the line guide bar in a line guide position as it is shifted up and down the transparent sheet. A guide slot is formed along the one side margin of the transparent sheet to hold the outer end of the line guide bar in sliding engagement with the line guide bar in sliding engagement with the transparent sheet.
DESCRIPTION OF DRAWING
For a better understanding of this invention reference may be made to the accompanying drawing, in which:
FIG. 1 is a top plan view of my invention inserted into a ring binder;
FIG. 2 is an end view of my invention taken along the line 2--2 of FIG. 1;
FIG. 3 is a perspective view of the line guide bar and associated magnet member;
FIG. 4 is a partial perspective view of the flexible transparent sheet and associated metallic strip attached on its one side margin; and
FIG. 5 is a partial top plan view similar to FIG. 1, except the flexible transparent sheet has been flipped over to the other side of the ring binder.
DESCRIPTION OF PREFERRED EMBODIMENT
Referring to FIG. 1, there is shown a conventional ring binder 10 in the open book position. Ring binder 10 has three spaced rings 12 which can be opened to insert or remove loose leaf paper 14.
A line guide device 16 embodying the principles of my invention is shown inserted on the left side of ring binder 10. A flat sheet of flexible transparent material of a size at least as large as the loose leaf paper 14 overlays the printed page on the left side of binder 10, and a line guide bar 20 is disposed across the flexible transparent sheet 18 and can be slidably repositioned up or down the sheet to follow the printed matter on the page beneath the line guide bar 20.
An elongated metallic strip 22 is attached along one side margin of transparent sheet 18 in a generally perpendicular relation thereto. The means for mounting the metallic strip 22 comprises an integral upturned flange portion 24 which is folded lengthwise at its approximate midlength to present two folded sections 26, 28 in general parallel relation. The metallic strip 22 is inserted through one of the end openings 30, and a fastener means is provided to hold the metallic strip 22 between the folded sections. One suitable fastener means could be eyelets 32 inserted through the folded sections 26, 28 at their ends and disposed outwardly of right-angled cut-out 34 formed at the opposite ends of metallic strip 22. Another suitable fastener means would be to heat seal the folded sections 26, 28 together to envelope the metallic strip.
A magnetic member 36 is secured to one end of line guide bar 20 in a generally perpendicular relation for holding the line guide bar at different positions by its magnetic attraction to metallic strip 22. Magnetic member 32 comprises a casing 38 having a base portion 40 and a recess 42 formed in an upstanding leg portion 44. A magnet is mounted in recess 42 as by cement 46, and the base portion is fastened to one end of line guide bar 20 by means of rivets 48. The line guide bar and associated magnet member are not new per se and are disclosed in all of the above identified Mendels patents. What is new and novel is the cooperation between the line guide bar 20 and transparent sheet 18.
For clear reading of the printed matter it is essential that the transparent sheet 18 lie flat on the printed page 14. When the thickness of the pages on the left side of the ring binder 10 is less than the width of folded sections 26, 28, it will be appreciated that the flange portion 24 must be positioned upwardly, as depicted in FIGS. 1 and 2 to permit sheet 18 to lie flat on page 14. In this orientation, the line guide bar 18 lies between the printed page 14 and transparent sheet causing some resistance to proper repositioning of the line guide bar. This resistance is substantially reduced by providing a line guide means 50 along the inner marginal edge of the transparent sheet 18.
Line guide means 50 comprises an integral flange portion 52 bent inwardly toward transparent sheet 18 into a generally parallel relation thereto. The inner marginal portion of surface 54 and flange portion 52 present an elongated guide slot 58 into which the outer end 60 of line guide bar 20 is disposed.
To provide quick attachment onto the rings 12, a fastener means 62 is provided at the inner marginal side of transparent sheet 18. Fastener means 62 takes the form of a plurality of T-shaped slots 64 extending inwardly of the inner marginal edge and flange portion 50. In the embodiment shown, the T-shaped slots are spaced to accommodate either a three-ring or two-ring standard binder. It is noted that the length of line guide bar 20 is selected so that its outer end 60 extends into guide slot 58 but would not intersect any of the T-slots 62.
By virtue of the hooking engagement of T-shaped guide slots 62 with rings 12 and the retaining action of guide slot 58 on the outer end of line guide bar 20, it is possible to flip the line guide device 16 from the left side (FIG. 1) to the right side (FIG. 5) of ring binder 10 or vice versa. When the user is done with both pages, the T-shaped slots 62 permit the line guide device 16 to be quickly removed without the necessity of opening the rings 12.
Although a number of materials could be used to form transparent sheet 18, the preferred material is a non-glare vinyl because of its durability and flexibility. Non-glare vinyls have been found very satisfactory in forming the two integral flange portions 24 and 50.
While there has been shown and described a preferred embodiment of the present invention, it will be understood by those skilled in the art that various arrangements and modifications may be made therein without departing from the spirit and scope of the invention.
