1. Field of Invention
This invention relates to bookstands, specifically to an improved product to hold and support books and other media for reading, writing and viewing.
2. Discussion of Prior Art
For many years, bookstands have been created to support the weight of books and hold them at an incline to reduce eyestrain, neck pain and muscular fatigue for the reader. Nearly all of these bookstands are made of wood, sheet metal or hard plastic and are intended for use on a tabletop. Hard materials cause them to be heavy, bulky, and expensive. They are uncomfortable and unstable in the viewer's lap, or on their stomach when lying down. Many of these bookstands are not portable.
The book support in U.S. Pat. No. 3,937,435 to Roberts, 1976 Feb. 10, has sharp edges and corners that could mar the book or a table finish, and would be unstable and uncomfortable when used in the viewer's lap. The book holder in U.S. Pat. No. 5,377,946 to Pannu, 1995 Jan. 3, may be used by the reader in bed, but it is large, and difficult to move. The reading stand in U.S. Pat. No. 5,720,465 to Peltzer, 1998 Feb. 24, is complex, difficult to use and expensive to produce.
The collapsible book stands in U.S. Pat. No. 4,116,413 to Andersen, 1978 Sep. 26, and U.S. Pat. No. 5,829,729 to Welch, 1998 Nov. 3, are hard edged and sharp. They are metal and are too heavy to be considered portable. The collapsible book stand in U.S. Pat. No. 5,413,305 to Leeb, 1995 May 9, is softer and may become compact and portable, but it only tilts the top up. It does not raise the entire book to more fully ease neck strain.
Accordingly, several objects and advantages of my air-supported book stand are:
Further objects and advantages are to hold large books open without obstruction of page turning. Because the surfaces upon which the book rests are able to conform to the shape of the book, larger books do not spring closed and do not flop open to other sections as they would if the resting surface were completely flat. In addition, the bottom edge of small paperbacks can be tucked into the shelf pocket enabling the book holder to keep a small book open to a page without hands even outdoors in a breeze. Still further objects and advantages will become apparent from a consideration of the ensuing description and drawings.

In accordance with the present invention an air-supported book stand in the preferred mode comprises an inclined member, attached to a vertical member, attached to a base, attached to a shelf against the lower front of said inclined member, each composed of walls of airtight sheet material, and containing air by way of a plugged air inlet.
A typical embodiment of my air-supported book stand is illustrated in
Accordingly, the air-supported book stand alleviates fatigue from the weight of the book, and also the weight of the reader's own hands and arms, which hold up the book. Unlike other products, my invention is soft and comfortable for lap use. Arms may rest in the lap, on the open pages of the book, or in the open void in the middle of the book stand, and if needed, thumbs may be used to hold the pages open. Furthermore, the air pillow aspect of my invention has the additional advantages that
An alternative embodiment is shown in

Another alternative embodiment flattens the inclined and base surfaces through the use of harder material on these surfaces as in
Although the description above contains many specificities, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently referred embodiments of this invention. For example, the air-supported book stand may be of different angles, shapes or dimensions, or may enclose different volumes of air or a number of separate volumes; use other shapes instead of circles in the base, use firm materials in combination with flexible materials; and use simple welds instead of internal spans (known as “I-beams” in the inflatables industry) and spans instead of simple welds.
Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
Vertical member 94 supports inclined member 92. Inclined member 92 and shelf 98 together support the book. Base 96 keeps the lower portions of shelf 98 and inclined member 92 at a fixed distance from the lower portion of vertical member 94 so that the stand remains erect at a predetermined angle. Circle welds 62-76 are to restrict the air contained in base 96 that would otherwise produce tabletop instability. Air inlet and plug 84, and airtight seams 42-60, serve to contain the air volume. The interruptions in the welds on folds 20-24 allow the stand to be filled from a single air inlet. Shelf 98 lifts larger hardbound books (
When deflated, my book stand is in very thin and will fold for compact storage or portability in a book bag. When deflation is not possible or desirable, a user may simply put an arm through the middle of the stand and keep both hands free for carrying other items.
Portable electronic devices can be held between shelf 98 and inclined member 92 thus lifting the display to a comfortable viewing height (
When seated without a table, tablet computer users are greatly aided in reading, writing and stylus control of applications when my air-supported stand is used in lap. The user is more upright, reducing parallax, eyestrain, neck, back, and arm fatigue, and the user can be more engaged in the meeting.
Electronic book readers will use my stand much the same as do printed book readers since they both involve mostly static viewing with the occasional page advance or page turn.
