ONE-PIECE BOOK momma Filed July 1, 1966 co srwc/o A. 6141144105 IN V E N T O R United States Patent Oflice Quiapo,
1 Claim ABSTRACT OF THE DISCLOSURE A book holder consisting of a panel member having a prop attached to one side and book engaging and holding clips attached to the other side.
This invention relates to a book holder which consists of only one piece and, therefore, very light and conveniem to carry along with the book or books.
The primary purpose of this invention is to provide the student population as Well as professionals and others who read books and magazines, with a very low-priced but very effective book prop or holder which, by reason of its being made of only sheet, is very handy and convenient to use.
Another object of this invention is to lighten the burden of the students and pupils in their studies in that the use of the device will make them feel more convenient and therefore more receptive to better concentration when they study their lessons.
In the drawings:
FIG. 1 is a front view of the non-operative position.
FIG. 2 is a side view of the device in its folded or non-operative position.
FIG. 3 is a side view of the device in its operative position.
FIG. 4 is a front view of the device in its operative position.
FIG. 5 is a side view of the tip of the secondary prop.
This invention consists of a single rectangular sheet 1 (FIGS. 1 and 2), of plain pliable but tough and strong material, of such dimensions as to enable it to contain or hold uprightly an open book which is made to lean against it.
The lower sides of a trapezoid, hereinafter referred to as the primary prop 2, is cut out at the lower middle portion of said plain sheet 1 (FIG. 1), leaving the middle portion of its top side 3 untouched, and further leaving said top side 3 uncut but considerably reduced in thickness such that said primary prop 2 can be easily bent to either side of the plain sheet 1. A secondary prop 4 is cut out on primary prop 2, leaving the base 5 of said secondary prop 4 uncut but considerably reduced in its thickness such that said secondary prop can be easily bent to either side of the plain sheet 1.
A plurality of slots 6 (FIGS. 1 and 4) are made in a straight vertical row on plain sheet 1, said row being in line with the tip 7 or secondary prop 4. Each slot 6 device in its folded or 3,447,770 Patented June 3, 1969 is large enough to allow the tip 4 to enter said slot.
At the lower right corner of plain sheet 1 (FIGS. 1 and 4) is cutout a pair of rectangular portions 8 and 9 which have rounded corners, leaving the base 10 of portion 8 uncut but its thickness considerably reduced such that said portion 8 can be easily bent to either side of plain sheet 1. Portions 8 and 9 are joined together at their upper ends. The lower tip 11 of portion 9 is completely severed from plain sheet 1, but its upper end 12, which is joined to the upper end of portion 8 as previously stated is reduced considerably in its thickness such that said portion 9 can be easily bent to either side of plain sheet 1. It shall be noted in the drawing that portion 9 is located at the far right of plain sheet 1.
Another pair of portions 13 and 14, similar to the pair of portions 8 and 9, is likewise cut out at the lower left-hand corner of plain sheet 1. The pair of portions 13 and 14 is identical to the pair of portions 8 and 9, with the only significant difference that while portion 9 is at the far right, its counterpart portion 14 is at the far left.
The lower side 15 of slot 6 is made thin, the purpose of which is shown in the next succeeding paragraph.
The tip 7 of secondary prop 4 is provided with a hook-like projection 16 (FIG. 5) at the front side of said tip 7, the purpose of which is to allow said hook 16 to engage with the thin lower side 15 of slot 6, thus preventing said tip 7 from slipping down whenever the propped open book is picked up together with the device so as to transfer same to another place.
The device is set into its operative position by simply pushing the combination of the primary and the secondary props 2 and 4 towards the side opposite the side of the hook 16 of the tip 7 of the secondary prop 4, and then inserting the tip 7 into the desired slot 6.
To set the open book against the device, the identical pairs of portions 8 and 9 and portions 13 and 14 are pushed towards the front side of the device, and the identical or corresponding portions 9 and 14 are tilted upwards so as to bring them clear of the pages of the open book. When the open book has been set on portions 8 and 13 and consequently against plain sheet 1, said portions 9 and 14 are then released, and by reason of the resilient but tough and strong quality of the mate rial that should be used in the manufacture of the device, said portions 9 and 14 automatically press down firmly the leaves or pages of the open book.
Having thus described my invention in detail, I now claim:
1. In a book holder consisting of a single piece or sheet having the qualities of a material which is resilient but tough and strong, the lower sides of a trapezoid having been cut out at the lower middle portion of said sheet, leaving the middle portion of the topmost side of said trapezoid intact and the end parts of said topmost side being considerably reduced, said out out portion serving as a primary prop of the plain sheet, the upstanding sides and tip of a vertically positioned triangular portion being cut out on said trapezoidal portion up to and beyond the topmost side-of said trapezoidal por- 7 of the secondary prop tion, and the base of which said triangular portion only considerably reduced in thickness, said triangular portion serving as the secondary prop of the plain sheet, a plurality of slots having been punched in a vertical row at the middle of the plain sheet, into which any of said slots the tip of the vertically positioned triangular portion which serves as a secondary prop may be inserted, there being a hook-like projection at the topmost tip of said secondary prop, a pair of rectangular portions having been cut out at each of the two lower corners of the main or plain sheet leaving the base of one portion of each pair uncut but conisderably reduced in thickness, the upper ends of each pair being joined together, and with the joined end of each portion having the free end being considerably reduced in thickness.
