Description: Cover device for subsequent mounting on books The present invention relates to a cover device for subsequent mounting on a book, in particular a paperback, and of the type described in the introductory part of claim 1. Books without stiff cover, that is paperbacks, normally can not be placed standing up, that is supported on a narrow side egde on a surface or a book shelf without a suitable side support, for instance book end or neighbour book. If a suitable separate side support is not used a such paperback normally will "collapse", if a neighbour book is taken out from the shelf, and therewith the book may be damaged permanently; and it is difficult to replace the neighbour book. In particular this concerns larger paperbacks, for instance telephone books or similar large "soft" books or booklets. The described problem may of course be solved by a kind of binding, where the book js provided with a cover with a back and a stiff front and back side member. This could be be optained by means of a traditional bookbinding, or by means of a loose bind or cover, which may be mounted by the user, and which possibly could be reused for new or other books; but it would however be a rather expensive solution. The purpose of the invention is to provide a cover device of the type described in the in¬ troductory part, and by means of which a good support of paperbacks, in particular of the telephone book type, may be obtained in a simple and cheap manner. The method according to the invention is distinctive in that said first cover part at a side is provided with fastening means adapted to secure said first cover part to a cover side member of the book, that the connecting part preferably is provided with folding lines or folding recesses, which stretch parallel with said narrow side of the book, and that said second cover part is provided with connecting means being adapted to connect said second cover part to said second cover side member of the book, said cover device being manufactured from material, which is capable of taking up or transmitting shearing forces. In a simple and cheap manner a cover device is hereby obtained, which at subsequent mounting may provide a good support of a paperback, for instance a telephone book, and of which paperback said second cover part, when it is not secured to said second cover side member of the book (front page), also - as a further advantage - may be used as put in book mark. In a preferred embodiment the cover device according to the invention is such provided, that said first cover part is adapted to be secured to an outer side of the rearmost cover side member of the book, and that last-mentioned cover part is adapted to be connected temporarily to an outer side of the front cover side member of the book. Preferably a cover device according to the invention is furthermore adapted to be adapted to stretch along a section of said narrow side of the book and to be mounted, so that a lowermost edge of said first cover part preferably flushes with a lowermost edge of the rearmost cover side member of the book. The cover device according to the invention may advantageously be such provided, that said second cover part is provided with decreasing height in the direction away from the connecting part. And preferably the cover device is further such provided, that said second cover part mainly is triangular, that is provided with sides, which in the direction away from the connecting part stretch towards preferably at the centre of the connecting part and in a distance therefrom placed connecting means. To make a correct placement easier of the parts of the connecting means being adapted to be secured permanently to said second cover side member of the book - for the mounting of the cover device - is temporarily secured to said second cover part. Hereby it becomes - by mounting of the cover device - extra easy to place this correctly dependent on the thickness of the book in question. In a particular simple manner the cover device according to the invention is such provided, that the connecting means for connecting said second cover part to the said second cover side member of the book consist of tape- or button-shaped velcro locks, of which the respective basis parts preferably are self-adhesive. The invention furthermore relates to a method for manufacturing a cover device according to the invention, which method is distinctive in, that the cover device is manufactured from a length of laminate consisting of a impregnated backing paper and a plastic sheet member, which on the side facing the backing paper with mutual distance is provided with longitudinal zones of an adhesive coating, said zones stretch along opposite edges of the plastic sheet member, that said first cover part is punched out from one of said longitudinal edge zones, that the connecting means at said second cover part are punched out from the other edge zone, that said folding lines of the con¬ necting part are provided inside said first edge zone at the side of the plastic sheet member opposite the backing paper, and that the connecting part and the second cover part are provided from the middle part of the plastic sheet member, which is not provided with adhesive coating. The invention is described in the following with reference to the drawing, in which: Figs. 1A and IB show a telephone book and an embodiment for a cover device, respec- tively, according to the invention, Figs. 2 - 4 show, how the cover device shown in Fig. IB is mounted on and is adjusted to the telephone book shown in Fig. 1A. Fig. 6 shows, how a cover device according to the invention may be used as a support, by way of example, for a telephone book, Figs. 5 and 7 show, how a cover device according to the invention may be used as put in book mark, by way of example, for a telephone book, Fig. 8 shows an other emdiment for a cover device according to the invention, while Fig. 9 shows a preferred embodiment for a cover device manufactured in accordance to the method according to the invention. The book shown in Fig. 1A is an ordinary paperback telephone book 2 of A4-format, that is a rather large and relative "soft" book, which not without a side support can be placed in vertical opright position on a short side edge 4 of the telephone book 2. The cover device 6 shown in Fig. IB is manufactured from thin plate material, for instance a suitable plastic sheet, and consists of a rectangular rearmost cover part 8, a connecting part 10 and a front cover part 12. The cover part 8 is on an internal side 14 provided with an adhesive coating 16, which temporarily is covered of a suiteable impregnated backing paper 18, which as indicated is adapted to be pulled of, before the cover part 8 - as shown in Fig. 2 - is mounted on a rearmost cover side member of the telephone book 2, so that the cover part 8 flushes with the short side edge 4 and with the side edge of a narrow side 20 of the telephone book 2 - opposite the back thereof. The connecting part 10 is - as most clearly shown in Fig. 2 - provided with folding lines or folding recesses 22 adapted to stretch parallel with said side edge of the narrow side 20, so that the "used width" of the connecting part 10 easily may be adjusted in accordance to the thickness of for instance the telephone book 2 (Figs. 3 - 4). The front cover part 12 is in a distance from the connecting part 10 provided with a tape-shaped velcro lock (american zipper) 24, the one part 26 of which (Fig. 2) in advance is secured permanently to the cover part 12, and the second part 28 of which (Fig. 7) - in order to make easier the mounting of the cover device 6 - is temporarily secured to said in advance mounted second part of the velcro lock 24 (Fig. IB). This means, that the cover device 6 - as a whole - is easy to mount sufficiently thight around the lower, external corner of the closed telephone book 2, which thereafter as shown in Fig. 6 - now without tendency to tumble over - may be placed in vertical opright position supported on the short side edge 4. When the telephone book 2 is used for its purpose, the cover device 6 may be used as a put in book mark (Figs. 5 and 7). In a preferred embodiment a cover device 30 - as shown in Fig. 8 - is manufactured from relatively stiff flexible plastic sheet material, which furthermore may be trans¬ parent. A cover part 32 is - as earlier described - provided with a self-adhesive coating with a temporary backing paper 34. Also a connecting part 36 is - as earlier described - provided with folding lines or recesses 36; on the other hand a front cover part 40 is now shaped triangular and provided with a circular velcro lock 42 at the tip end of the cover part 40. Alternatively the cover part 8 may be adapted to be secured to the book by means of any suitable adhesive means or fastening means, for instance staples. Preferably the cover part 8 is adapted to be secured external on the rearmost cover side member of the telephone book 2; but of course the cover part 8 may also be adapted to be secured internal on the rearmost cover side member of the book. The same applies for the cover part 12, which may be adapted to be secured temporarily either to the internal side or to the external side of the front cover side member of the telephone book 2. The temporary fastening of the cover part 12 - which in the shown embodiments are made by velcro locks 24 or 42 - may possibly be provided as another form of relock system, for instance a snap fastener or a magnetic catch. The cover device described and defined may - within the scope of the invention - have any suitably embodiment and may be manufactured from any suitable material, when only the main aspect of the invention is considered, namely that it is possible to connect for instance rearmost cover side member and front cover side member of a paperback by means of a cover device adapted to taking up or to transmit the shearing forces, which might occur between the respective cover side members of the book. The cover device according to the invention is preferably manufactured by the stated preferred method, that is - as shown in Fig. 9 - from a length of laminate 44 consisting of an impregnated backing paper 46 and a plastic sheet member 48, which on the side facing the backing paper 46 with mutual distance is provided with longitudinal zones 50 of an adhesive coating 52. With reference to Fig. 8 the cover device consists of a flexible plastic sheet member 48 and comprises a cover part 32, which by the method according to the invention is connected with adhesive coating 52, as this only temporarily fixes to the impregnated backing paper 46, a connecting part 36 being provided with folding lines or folding recesses 38, which are made by means of less high cuttingrollers of a roller punch currently punching out the whole cover device. This cover device furthermore compri¬ ses a front cover part 40 being connected with a carrying part 54 for a velcro lock member 56, said carrying part 54 is adapted to be bend around and to be glued onto the internal side of the tip part of the front cover part 40. A separate circular carrying part 58 for a velcro lock member 60 which is also provided with an adhesive coating, is pun¬ ched out at the same as the plastic sheet member 48. The separate carrying part 58 is adapted to be secured to the front cover page of a book, and it is mounted in a simple manner by securing temporarily its velcro lock member 60 to the velcro lock member 56 of the cover part 40, so that the carrying part 58 automa¬ tically is secured in a correct position, when the cover part 40 and the connecting part 36, respectively, are folded thightly around the open side egde of a certain book, for in¬ stance a telephone book. It will be within the scope of the invention, that the outmost tip end of front cover part 12, 40 on internal side is provided with an adhesive coating of the type, which perma¬ nently or at least several times allowing the front cover part 12, 40 to be secured to the front cover side member of the book. And a such adhesive coating may be applyed on internal side of the front cover part 40 in accordance to the stated method, as one of said edge zones of the adhesive coating just may consist of a such adhesive coating, which may replace the said velcro lock members 56 and 60 with belonging carrying parts 54 and 58, that is that the cover device may be manufactured from a similar more narrow length-shaped laminate, where each of the longitudinal edge zones 50 are provided with different types of adhesive coating.
