This application relates to four post book holder designs.
2. Prior Art
My patent searching consisted of looking at book holders at book stores. Further searches at WWW.freepatentonline.com reviled many four (4) post designs. There were book holders with page retainers that have to be moved in order to turn book pages. Page retainers in my design are easy to adjust. Once adjusted only slight adjustments are necessary during the reading of the held book. Page retainers do not have to be readjusted or moved to turn the read page of a held book.
Holder consist of a base with legs to adjust reading angle. A upper movable fence and a lower stationary fence are provided to hold books in place. Movable tab assemblies with page retainers are attached to these fences in slots provided. Tab assemblies are attached to the fence slots with coil springs and steel pins. This attachment allows the tab assemblies to be moved perpendicularly and/or side to side. This tab movement results is complete adjustability of the page retainers. Turning of the held book's read page is accomplished without any need to move or adjust the tab or page retainer assemblies.
FIG. 1—isometric top view of holder showing upper movable fence in a open position.
FIG. 2—isometric bottom view of holder showing upper movable fence in a open position.
FIG. 3—view of holder showing where section areas A-A, C-C, D-D are located.
FIG. 4—section view A-A showing how the tab assemblies are constructed and connected thru the slots in the top and bottom fences.
FIG. 5—C-C section of top fence/book cover retainer bar assembly.
FIG. 6—D-D section of bottom fence/book cover retainer bar assembly.
FIG. 7—Book in holder showing B-B section.
FIG. 8—B-B section of book cover/retainer bar view.
FIG. 9—isometric view of holder folded into storage mode.
The tabs are fastened to the fences as shown in
FIGS. 5,6 show the top fence 12 Sec C-C and bottom fence 14 Sec D-D. These two sections show the cover retainer bars 46, & 48. Book hard covers slip under these bar retainers when hard cover books are retained by the holder.
Beginning with holder in storage mode
With the open book positioned in the holder the page retainer assemblies 30,32,34,36 can be rotated back so that the retainers 38,40,42,44 are positioned over the book's pages.
Adjustments of the page tab assemblies 16,18,20,22 is done by moving them in the fence slots 50,52,54,56. This positions the page retainers 38,40,42,44. Tab assemblies 16,18,20,22 are spring loaded and single pinned to the fences thru the fence grooves 50,52,54,56 (
These adjustments will result with the pages of the book being held down in an acceptable reading position. Proper retainer 38,40,42,44 adjustments will result in a unobstructed view of the book's words. Page retainers 38,40,42,44 can be rotated, if required, to clear book words if the book top and bottom margins are narrow. In this position they will still retain the book pages. Room is left between the adjusted book pages and the holder base. This is to facilitate page turning.
Page turning without any further adjustments to the page tab assemblies 16,18,20,22 is accomplished by placing the tip of the right hand index finger at the top edge of the book's right page and lifting the page. The lifted page will slip out from under the top right page retainer 40. When the page is moved to the left side of the book holder the page will slip out from under the bottom right retainer 44. Since space was left between the open book retained pages and the holder base, the turned page can easily be tucked under the left top and bottom page retainers 38,42. The turning of pages in this holder is much like turning a hand held book page. Turning of pages is accomplished using one hand only. At no time during the turning of pages is any further adjustments required of the page tab assemblies 16,18,20,22. Some minor adjustments of the tab assemblies 16,18,20,22 may be necessary as the book is being read. This is due to the book's thickness and page springiness changing as the pages of the book are moved side to side.
The installment and holding operation of books without hard covers is accomplished the same way as explained above. Of course there are no hard covers to slip under the fences 12,14 cover retainer bars 46,48. The lack of hard covers will not effect the holding of these types of books since all books in this holder are held in place by the page tab assemblies 16,18,20,22 and the leading edge of the hard cover retainer bars 46,48.
