A BOOK

Abstract: A book (10) comprising a plurality of pages in a stack (11) and a sleeve (12) surrounding a portion of each of said pages, said pages being slidable relative to said sleeve (12) and each other, and said book further comprising means for preventing said pages from being slidably removable from said sleeve (12).

Description: A BOOK This invention relates to a book, especially a type of book which might be used for a children's quiz. Books of the prior art are usually bound by gluing or otherwise fastening pages on one side so that the pages spread open opposite each other in pairs. A prior art children's quiz book comprises a number of pages which are fastened together by a rivet. Questions and answers printed on the pages are exposed and obscured by rotating the pages around the rivet. According to the present invention, there is provided a book comprising a plurality of pages in a stack and a sleeve surrounding a portion of each of said pages, said pages being slidable relative to said sleeve and each other, and said book further comprising means for preventing said pages from being slidably removable from said sleeve. Specific embodiments of the invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1 shows a sleeve bound book of the present invention; Figure 2 shows the detachable nature of the sleeve of the book of the present invention; Figure 3 shows a further embodiment of the book of the present invention; Figure 4 shows a book according to the present invention with through holes in the sleeve; Figure 5 shows a further embodiment of the present invention comprising three stacks of pages; and Figure 6 shows an alternative way of fastening the pages to the sleeve (only one page is illustrated). Referring now to Figure 1, a book 10 comprises a plurality of pages 11 in a stack. The pages 1 1 are bound together by a sleeve 12. The pages 1 1 are held in the sleeve 12 such that each page 1 1 of the plurality of pages may slide relative to each other page 1 1 and to the sleeve 12 but may not slide out of the sleeve 12. The sleeve 12 surrounds a portion of each page 1 1. In the preferred embodiment, the pages 1 1 are prevented from sliding out of the sleeve 12 by protrusions 13 at each corner of each page 1 1. In this way, the dimension of the pages 1 1 at the outer edges is greater than the inner dimension of the sleeve 12 and the dimension of the portion of the pages 11 surrounded by the sleeve 12 is less than that of the inner dimension of the sleeve 12. As will be appreciated, if sleeve 12 is wide enough such that the plurality of pages 1 1 are prevented from rotating in the sleeve 12, then only one protrusion will be required each side of the portions of the pages surrounded by the sleeve 12. If pages 1 1 are printed in an area designated approximately by box 14 as indicated in Figure 2, the print area 14 may be exposed to or obscured from view when the page is slid with respect to the sleeve 12 or the other pages. In this way, the book of the present invention may be used as a quiz book. For example, a question can be printed on a page on one side of the portion surrounded by the sleeve 12 and the answer printed on that page on the other side of the portion. Then, the question can be exposed to view whilst the answer is obscured, the answer being revealed when the page is slid with respect to the sleeve 12 and/or the other pages. Alternatively the sets of questions and answers can be printed on opposite sides of the pages. This allows the book to be used as a quiz book. Ideally the pages have an aspect ratio of at least 2 to 1, sliding through the sleeve 12 in the direction of the longest side of the page. In this way, the amount of information which is fully obscurable and revealable is maximised. Similarly, ideally the sleeve 12 is at least a third as wide as the width of the pages 1 1. As is also shown in Figure 2, the sleeve 12 is detachable from the pages 1 1 and in this way, different pages 11 may be filled into the sleeve. As is shown in Figure 3, the plurality of pages may be arranged in two (or more) adjacent stacks 15. In this way, the number of obscurable print areas 14 is doubled. Of course, each of the pages 1 1 may have printing on both sides. By providing through holes 16 in the sleeve or through holes 17 in the pages 1 1, further combinations and permutations of obscurable and revealable areas are possible. The holes 16, 17 could also be transparent areas. As shown in Figure 5, several stacks 15 of pages may each be individually held in a sleeve 12 and those sleeves 12 may form part of the same body. A different embodiment for securing the pages in the sleeve 12 is shown in Figure 6 in which the pages 11 do not have any protrusions (only one page is illustrated). In this embodiment, the sleeve 12 has an elongated member 18 fixedly attached to it. The elongated member 18 is held by sleeve 12 in a position perpendicular to the plurality of pages 1 1. The member 18 passes through the inside of sleeve 12 from one side of the sleeve to the other. The plurality of pages 11 each have an elongated cut out slot 19 through which the member 18 passes. The pages 1 1 can slide from a position in which one end of the slot 19 abuts with the member 18, to a position where the other end of the slot 19 abuts the member 18. In this way, the pages 1 1 may slide relative to the sleeve 12 but are not slidably removable from the sleeve 12. Other embodiments are possible. For example, in the embodiment illustrated in Figure 6, if the sleeve 12, or a part of the sleeve 12 is arranged to pass through the cut out slot 19, the elongated member 18 can be dispensed with.

Claims: CLAIMS 1. A book comprising a plurality of pages in a stack and a sleeve surrounding a portion of each of said pages, said pages being slidable relative to said sleeve and each other, and said book further comprising means for preventing said pages from being slidably removable from said sleeve. 2. The book according to claim 1, wherein at least one page of said plurality of pages, when in an extended position, has an area of printing exposed, said area of printing being obscured by said sleeve or another page of said plurality of pages when said at least one page of said plurality of pages is in a retracted position. 3. The book according to claim 1 or claim 2, wherein said book is a quiz book, questions being printed on most pages on one side and corresponding answers to said questions being printed on the other side of the same page. 4.
