Description
TITLE
FOLDED SHEET
BACKGROUND
This invention relates to folded sheet material, regardless of whether it is in a folded or unfolded condition.
It is known to fold maps with a first set of vertical concertina folds (which term means that the folds are alternately towards and away from the front of the sheet) and, once the map is so folded, to impose a second set of folds (not concertina) that are horizontal. It is further known for such a map to have a stiffening portion which extends over the whole of one corner segment produced by the folds and beyond this for a similar area outside the map so that when the map has been folded completely the outside stiffened portion can be folded over the map so that the map is wholly contained between the two parts of the stiffened portlon that sre hinged together.
THE INVENTION
For the purposes of the ensuing description and claims, "sheet material" is hereby defined as sheet material whlch ha~ folds in it, regardless of whether lt is ln a folded up condition or not unless the context otherwise requires, and further is a material that takes folds at which it can be easily unfolded (without the folds disappearing) and refolded. It may be paper, or a paper-like material such as plastics sheet on which books are commonly printed, or may be very thin card or any other suitable flexible material. It is conceivable that the sheet material may be stiff exccpt at the folds, e.g. very thin cards interconnected by paper or cloth, but thls i9 deprecated aq not allowing full realisation of the advantages of the invention.
27~14-2 The invention is a sheet of material which has folds in it, regardless of whether it is in a folded up condi~ion or not unless the context otherwise requires, and that takes folds at which lt can be easily unfolded, without the folds disappearing, and refolded, the sheet having a first set of concertina folds and, so as to be transverse to these when the sheet is folded with these folds, a second set of concertina folds, characterised by the sheet being provided with two diagonally opposite, defined, stiff portions at segments thereof, which segments are at or near diagonally opposite corners of the sheet and defined by fold/s and/or edge/s thereof.
Thls enables the sheet of material to be unfolded in a slngle movement ln whlch one hand grasps one of the stiff portions and the other hand pulls the other stiff portion away from the flr~t one.
Although one or both ~ets of folds may be non-parallel, e.~, convergent, and/or one or both of the stlff portions may, when the sheet 1~ properly folded, not be outer portions, ln a preferred embodiment the sheet i8 rectangular, the sets of folds beln~ mutually perpendlcular and parallel to the respective edges of the sheet, and the stlff portlons belng such as to be at the out~lde of the sheet when lt ha~ been folded by the first set of fold~ and then al~o by the second set of fold~ and belng at least as large as the re~pectlve corner secJments of the sheet.
In this case, and partlcularly lf the flr~t set consi~ts of an odd number of folds and the second set con~i~t~ of an even number of folds, one hand can grasp the back ~tlff portion, whlle ~-;
the other hand can grasp the front stiff portion and pull it first downwards and then sideways turning it over, so as to open the sheet with what in practice amounts to a single movement, assuming the sheet to be flexible at and near the folds. By ~xperiment, the most suitable folding for this action has been found to comprise five folds in the first set and two 1 2a ,', -~'i ".
.., ,,. _,, " ~", --` 1 320233 folds in the second set. Furthermore, if the stiff portions are slightly larger than the respective corner segments of the sheet it is easier to grasp the stiff portions. Also it is relatively simple to reverse the action and fold up the sheet again with a single movement. If this facility is then combined with the stiff portions being provided with holding means adapted to hold the portions together to keep the sheet folded, a particularly convenient embodiment is provided, one which can be rapidly unfolded and rapidly refolded and kept in position without undue fiddling. The holding means may comprise oppositely magnetised parts of the respective stiff portions or (though this has not been found so effective) may comprise hooked material and looped material at the respective stiff portions.
The invention is particularly suited to printad sheet material intended to be carried around in the pocket (e.g. for the uses indicated below) for which purpose the folds may divide the material into segments of about 4 to 8 cm. width by about 6 to 12 cm. length.
It is preferred thst the whole package should be roughly the size of a credit card, i.e. with the folds dividing the material rectangularly into segments of about 5 to 5~ cm. width by about 8 to 8~ cm. length.
In a preferred embodiment, the material (apart from the stif portions) is paper or paper-like material (e.g. of plastics) and the stiff portions are of semi-rigid material, principally of plastics (e.g. apart from magnetisable material for the purpose mentioned above), attached to the remainder of the material.
An embodiment which has particular uses in awkward s1tuations is produced if at least one of the said diagonally opposlte stifF portions (usually the front one) is sufficiently massive to allow single-handed holding and openlng of the shaet. In this case, the back stiff portion is held ln one hand with the massive front portion resting lightly on the remainder of the folded material and ~hen this is jerked so that the massive front portion flies away from the gra~ped back portion, thu~ automatically enabllng the sheet to be held and opened, both with one hand.
DESCRIPTION OP THE D~AWINGS
Reference will now be made by way of example to the accompanylng drawlngs in which.-Figures 1, 2, 3 and 4 show successive stages of openlng, l.e. unfoldlng, ~in that order) of an embodlment of the invention and show ln rever~e order (as indlcated by the arrows) successive ~tages ln closlng, l.e. foldlng up, the embodiment; and Flgures l, 4 and 5 show alternative features ofembodlment~ of the lnventlon.
Re~errlny to the drawlngs, and partlcularly Figure 4, a ~heet of paper 10, whlch 18 a sheet of materlal a~ hereln~efore deflned, ha~ a ~lr~t ~ot of concertlna folds 12 and, 80 a6 to be tran~ver~e to these when the sheet 1~ folded wlth these folds into tho po~ltlon ~hown ln Plgure 3, a second set of concertina folds 14, the sheet belng provlded with two stlff portlons 16, 18 havlng deflned edges and being located diagonally opposite to each other at ~egments 20,22 of the ~heet 10, which ~egment~ are at or near dlagonally oppo~lte corner~ 24,26 of the ~heet and are deflned by folds 12,14 and edge~ 28,30 of the sheet 10.
The sheet 10 15 rectangular when flattened, a~ wlll be - 2791~-2 easily inferred from Figure 4, the sets of folds 12, 14 being mutually perpendicular, and parallel to the respective edges 28,30 of the sheet 10, and the stiff portions 16,18 are such as to be at the outside of the 4a A~
sheet 10 when it has been folded by the first set of folds 12 (as seen in Fig.3) and then also by the second set of folds 14 (as seen in Fig.l), and the stiff portions 16,18 are at least as large as the respective corner segments 20,22 of the sheet 10.
It will be seen from Fig.4, that the first set consists of an odd number of folds 12, in fact five of them, and the second set consists of an even number of folds 14, in fact two of them.
For ease of grasping and to protect the sheet 10 and its folds 12,14, as explained above, the stiff portions 16,18 are in fact slightly larger than the respective corner segments 20,22 of the sheet 10, perhaps 2mm. on each side if the segments are of credit card size, as discussed below (and above).
The stiff portions 16,18 are preferably (for the reasons indicated above) provided with holding means adapted to hold the portions 16,18 together to keep the sheet 10 folded, in the position shown in Fig.l.
A particulsrly convenient form of the holding means comprises a known magnetic arrangement indicated schematically in Fig.l, in which small ad~scent areas 32 of each stiff portion 16,18 are magnetised with alternate poles on the inside of each stiff portlon 16,18, which portions are psired such that oppositely magnetised parts of the portlons 16,18 face each other through the folded paper sheet 10.
Thls is a known device and holds the portions 16,18 closely together by magnetic force bridging the eighteen thicknesses of sheet 10 thus clamped between portions 16 snd 18. An alternative ernbodiment is shown in Fig.4, in which the holding means comprise strips 34,36 of hooked material and looped material (e.g. that known under the trade name VELCR0) at the respective stiff portions 16,18, though this ls found ---` 1 320233 in practice to be less convenient than the magnetic feature as it }Pquires a much wider margin of excess size of portions 16,18 over the size of segments 20,22 and much t~inner paper sheet 10.
The embodiment is primarily directed to use as a pocket-held device and, as such, its preferred size is with all of the segments shown in Fig.4, into which sheet 10 is divided by folds 12 and 14,being about 4 to 8 cm. in width and about 6 to 12 cm. in length. The most convenient size is approximately that of a standard credit card, in which case the sheet 10 of material is divided rectangularly into segments of about 5 to 5~ cm. width by about 8 to 8~ cm. length.
Preferably, the stiff portions 16,18 are of plastics material such as is commonly used for credit cards. This enables portion 16 to be grasped in the left hand and portion 18 thrown outwards and downwards, to the right as seen in the drawings, so that sheet 10 opens automatically, going through the positions shown successively in Figs,2, 3 and 4. The portion 18 can then be grasped with the right hand and pulled slightly away from portion 16 to hold the sheet stretched and any text thereon easily readable. To close the sheet 10, portions 16 and 18 are grasped in the left and right hands respectively with the palms facing the viewer of Fig.4 and the portion 18 is then brought with the rlght hand in a movement indicated by arrow 38 towards the left and turning over portion 18 until it and sheet 10 reach the position shown in Fig.3. The movement is then continued upwards, over and back as indicated by arrow 40 and successively into the positions shown in Flg.2 and Fig.l.
In an alternative embodiment, a border segment 42 is normally kept folded, e.g. to secrete text, and the "corner segment" referred to above --` 1 320233 is the one marked 22 in Fig.5. This is then defined by edge 28 and two folds 14 and 44. Fold 44 is not part of the concertina folds 14 as it is in the same direction as the adjacent fold 14 shown in Fig.5.
By making the whole sheet fold up into a size similar to that of credit cards, it can be placed in a standard credit card wallet. The sheet can comprise one or more maps, can be a phrase sheet, a calorie sheet, a wine sheet (including both data and a map). The sheet may contain business information or lists of E-coded food additives. Important uses of sheets embodying the invention are:-1. Travelling: e.g. maps, phrases, dictionaries, business/executive information.

The sheet can comprise one or more maps, can be a phrase sheet, a calorie sheet, a wine sheet (including both data and a map). The sheet may contain business information or lists of E-coded food additives. Important uses of sheets embodying the invention are:-1. Travelling: e.g. maps, phrases, dictionaries, business/executive information.
2. Check-out/shopping: dining, wine, cheese, diet (?alorie , salt, cholesterol, -content).
3. Leisure: photography (e.g. instructions), watching (e.g. birds, trees, aeroplanes).
4. Emergency: first-ald, codes.
It is also conceivable that embodiments of the invention, perhaps when the folds are not parallel to each other or are not mutually perpendlcular, may constltute magicians' tricks.
