TT.'rT~NTr~T. PROBLEMS
5 When r.r,nC~ llPring the present standpoint of techniques as clPcrrlh~-l above, it will be seen that a tprhnirAl problem resides in ~;w-~LLu-:Ling a picture or text display unit which can be easily A - ' 1l e~ and easily dismantled, with the aid of solely two sheet-like panels and which in an erected or 10 ;~Rqpmhl ~-1 state can be readily given difierent degrees of stability in accordance with the ~ nc of the picture-carrying panels in relation to a structure supporting surface, and with which when dismantled, the panels can be readily rolled to a cylinder form without destroying or 15 ' _ ' n~ the panels .
It will also be seen that a t~rhn~cAl problem resides in rPAli7;n~ the qign1firAnre of allowing the panels to be rolled into a cylinder form in a manner such that any 20 P~LIIIall~lL def-,L-I,aLions caused when rolling-up the panels will be compensated for when two or more sheet-like panels are brought into mutual coaction in an Aqsomhl P~l or fitted state by virtue of bending the panels perF~n~1 nlll Ar to the perma-nent deformation when a~_ ' lln~ the panels to form said ,~ LL U~:LUL~,.
It will also be seen that a tPrhn1rAl problem resides in rP~ n~ the significance of needing to fasten to two mutually ~IrpOc~ ng edge parts of one picture-carrying panel 30 f irst parts of two-part coupling devices, and of f astening to the mutually opposing two edge parts of the second panel second parts oi two-part coupling devices, and by r~Al~7tns that the distance between the first coupling parts on the first panel will differ from the distance between the second 35 co--rl ln~ parts on the second panel.
It will also be seen that a tPrhn1r~1 problem is one of WO 9~/332S3 r~ Jq~
rP~ n~ the signlficance that are associated with and the advc~ yt:s that are afforded by the possibility simple and known, readily hPnrl~hl P two-part rollrl i ng devices .
5 Another tP(-hni--~l problem is one of rP~1;7~n~ the advantages that are afforded by configuring respective coupling devices that one r~llrl in~ part will define a gap, and such that the gaps of the two first coupling parts associated with the first panel will face towards one another, and therewith also 10 to realize the necessity the second coupling parts rlPf;n~n~
a gap such that the gaps of the two second coupling parts associated with the second panel will face away from each other .
15 It will also be seen that another tPr hnlr~l problem is one of realizing the significance of and the advantages afforded by ~hnn.~ing distance differences between the first rrlllrl in~
parts associated with the first picture-carrying panel and the second coupling parts associated with the second picture-20 carrying panel which are greater than 10% and normallysmaller than 60%, and also in realizing that in normal cases, the difference in distance shall lie between 5 and 30%.
It will also be seen that a te(~hn~mnl problem resides in 25 rP~l ;7~n~ the advantages that are afforded by producing respective panels from plastlc sheet material that has a square or L~ yular surface extension, and by forming the first and/or the second part of respective two-part coupling devices from strip material which is fastened to the rear 30 side of said panel with the aid of fastener means.
Another ter~hnlr;~l problem in this regard is one of rPAl~7~ng the q~gnlf1r.~n~!P of using a fastener means which has the form of Velcro~ tape, magnetic strip or double-sided adhesive 35 tape, or alternatively to use an elastic and springy rCl~ellt:L
means in the construction of a picture or text display unit of the aforesaid kind which can be readily ;lqqpmhl Pcl and W0 9~133253 2 1 8q7 79 readily dismantled.
It will be seen that another ~rhn; r~l problem resides in the R~nlfir;lnr~ of giving the first and the second parts of the 5 coupling device the form of a b~nfl~hlP or flexible plastic strip whose hf~nrl~h i 1 ~ ty is greater than the hpnrl~h~ 1 1 ty or f lexibility of the picture-carrying panel, therewith to enable the plastic strip to be bent to a small radius of curvature without being deformed plastically to a greater 10 extent than the material of said panel.
It will also be seen that a tPrhni r~l problem resides in rP~117~n~ those advantages that are afforded when, in the a,,L. ' le~l state of said two sheet-like panels, the outwardly lS facing picture or text displaying surface of a first panel is slightly concave in one plane, normally a horizontal plane, while the outwardly facing picture or text display surf ace of the other panel is convex and has bottom edge surf aces which extend between said edge parts of the two 20 panels such as to support the ~LLuuLuL~ on a flat underlying supportive surf ace.
It will also be seen that a tPrhn~r~l problem resides in realizing the UUll~ U~I~ S of and the advantages afforded by 25 making the one panel more rigid or stiffer than the other panel, so as to be able to change the external shape of an i~ccPmhl Pd display unit.
A further tPrhn~r~l problem is one of realizing the advantag-30 es that are afforded when a display unit of the aforesaid kind is comprised of more than two picture-carrying panels.
Another ~Prhn~r~l problem is one of realizing the advantages that are afforded when the parts of said rollrl ~ ng device can 35 be orientated in a direction which deviates from a parallel orientation .

W0 95/33253 F~
2 1 8~779 Another tPrhn~r~l problem resldes in seeing the benefits of forming the two parts of respective coupling devices from mutually coactable strips, Velcro~lD tapes, pPrr-nPntly magnetized strips, double-sided adhesive tape or like means 5 attached in a known manner to respective picture-carrying panels .
It will also be seen that a tPrhn~l problem resides in providing a uu~ Luu~lon in which a first panel will present lO a flat, or at least a generally flat display 3urface while using the characteristic features of the construction described in the aful, I loned Swedish patent application.
It will also be seen that a tPrhn1r~1 problem resides in the 15 ability to provide simple coupling means which despite the ~U~ y cl,l ' L:j being located at a given distance from one edge surface 2re able to provide this poq~h~1lty.
Another terhnlr~l problem is one of rP~ in~ the signifi-20 cance of using adhesive tape as said cn-~~rl 1ns devices, and also to realize the significance of adapting the point of ~1, ' t of said adhesive tape so that solely the display surface of the first panel will be flat or have an adapted ~.:Ul VCll.Ul'd.
Another ~erhn~r~l problem resides in rP~ll71n~ that the second coupling parts of respective two-part coupling devices may have the form of two pivotally connected magnetic strips of which one is fixed to the edge surface of the first panel 30 and one is adapted for coaction with a magnetic strip fixed ad~acent to the edge surface of the second panel.
It will also be seen that a tPrhnlr~l problem is one of re~1171ng the fll -lnn~n~ rules that are required for a 35 coupling device to provide a flat display surface on solely the f irst panel .

SOLUTION
With the intention of solving one or more of the aforesaid 25 te~ hnl~l problems, the present invention takes as its starting point an easily ~q~ fl and easily dismantled picture or text display unit which is comprised of at least two sheet-like panels whose outer defining surfaces may be quadratic or rectangular in shape with the exception of the 30 upper edge surfaces and/or side surfacesr when ~udged to be suitable .
,~rrr~r~l~ns~ to the invention, first parts of two-part coupling devices are each fastened ad~acent a respective edge of two 35 mutually opposing edge parts of a first panel, and the second parts of said two-part coupling devices are each f astened ad; acent a respective edge of two mutually opposing edge .. _ . ... _ _ . . . , . .. .. , . . . _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ WO 9S1332S3 r ~ Jq(~ ~
parts of the second panel, wherein the horizontal distance between the courl inS parts associated with the first panel differs from the horizontal distance between the second coupling parts of respective coupling devices associated with the second panel.
According to proposed ' '~ I i that fall within the scope of the inventive concept, each of the first rm-~nl ~n~ parts defines a gap, with the gaps defined by the two coupling parts associated with the first panel facing towards one another .
Each of the second rollrl;n~ parts also defines a gap, with the gaps defined by said two second coupling parts associated with the second panel facing away from each other.
According to the present invention, it is n~ C~ I y for the difference in the between the first coupling parts and the second rol-rl1n~ parts to be greater than 10% and preferably less than 60%, normally between 15 and 30%.
~rcrr~1n~ to one embodiment of the invention, respective picture or teYt-carrying panels have the form of plastic sheets and the first and/or second parts of respective 25 coupling devices have the form of a strip attached to said panels with the aid of a fastener means.
In this regard, the fastener means may have the form of Velcrd5 tape, magnetized strip, double-sided adhesive tape or 30 the like, and the fastener means will preferably be slightly elastic and springy.
According to another P~ho,ll It of the invention, the first and the second coupling parts may have the form of a flPY~hl~

The stif fness of one picture-carrying panel may conveniently be greater than the stiffness of the other panel.
According to the invention, the display unit is structured so that when two picture-carrying panels are brought together and f astened to one another by means of said two-part coupling devices, the outwardly facing surface of one panel 10 will have a slightly concave ~;ulvatule in a defined plane, such as a horizontal plane, and the outwardly facing surface of the other panel will have a convex ~ulvelLul~: with bottom edge surfaces that extend between said edge parts of the two panels so as to support against an underlying supportive 15 surface.
The invention also relates to the sheet-like panels in a dismantled state of the picture or text display unit, with said one or said second parts of respective coupling devices 20 being bc~n~l~hle to a cylinrlr~r~ shape, wherein the height or length of the cylinder thus formed corresponds to the width of respective panels.
The invention also enables the cross-sectlonal shape of the 25 unit to be changed by usilig three or more different or similar picture-carrying panels and/or by rhiln3~ n~ the orlentation of the coupling parts of respective r.nllrl i n3 devices .
30 In accordance with the invention, there extends between the first coupling parts associated with the ~irst panel and the second ro--rl 1 n3 parts associated with the second panel a fastener device by means of which the first panel can be given a flat or generally flat display surface.
According to ~l~L~l~:d . '~'~ ~:, that lie within the scope of the inventive concept, said fastener device has the form ~0 95/33253 P~ 5'C ~qC ~
2 1 8q77q of an adhesive tape whose one edge part is f astened to the second panel and whose other edge part is f astened to a magnetic strip on the first panel.
5 In additlon, the edge surface of the second panel is adapted to rest supportingly against the f irst panel adi acent an edge-related magnetic strip.
According to one preferred pmho~ , said device is 10 comprised of said second rol-rl ing part in the form of two pivotally connected magnetic strips, of which one is fastened to the first panel adjacent its edge surface, and one is adapted for coaction with a magnetic strip fastened ad~acent the edge surface of the second panel.
The length and the ~h~rknPqR of said two magnetic strips are chosen in relation to the ~hirknPRR and stiffness of respec-tive panels, such that one panel will obtain a flat display surf ace .
The two magnetic strips will preferably be identical with regard to cross-section and length.
ADVANTAGES
The adv~l.~c.y~s primarily afforded by and characteristic of an inventive picture or text display unit reside in the ease in which a few, two or more, sheet-like panels can be ARRPmhl P~l to form the unit while being held together by 30 coupling devices, and which can be ~ust as easily dismantled.
The panels may be made from a material which will enable the panels to be readily bent or f lexed in the absence of any plastic deformations that may have a deleterious effect on the external shape of the as~ ' 1P~1 units, since when 35 A ' 1~l the panels are intended to curve in a direction perpPn~llrl-lA~ to any such deformation.

2~89779 Further zidv~-lL~Iy~s that are afforded by an inventive picture or text display unit reside in the provision of conditions which enable a flat, or generally flat, display surface to be obtained on the first panel with the aid of an especially 5 configured devLce coacting between the coupling parts of a two-part coupling device, even when the panels are made from a readily h~n~lAhl~ or flf:~lr;hl~ material.

;n~ OF 7~MRl~nTM~NTS NOW
Figure 1 is a perspective view of a picture or text display unit 1 in an a~ state, said unit comprising two sheet-like panels, i.e. a first panel 10 and a second panel 20.
35 The first panel 10 has an outwardly facing surface lOa on which a desired picture or text can be mounted.
.. , .. _ _ _ . . _ _ _ _ _ _ _ _ _ _ _ _ _ ~fo 95l33253 P
~ 218977~
The second panel has an outwardly facing surface 20a onto which a picture or text can be mounted, similar to the surface lOa.
5 The first panel 10 has an inwardly facing surface lOb, and the second panel 20 has an inwardly facing surface 20b.
The first panel 10 has a rectangular surface extension of width "b", coL ~ n~ to 70 cm, and a height "h" corre-qron(l1n~ to 2 m.
The second panel 20 has a width "bl" corr~cp~n~1 n~ to 85 cmand a height "h" corrl~cr~n~lin~ to 2 m, and has also a rectangular surface extension or shape.
Both panels 10, 20 are produced from one and the same material have mutually the same stiffness and ~h1~ n~cc.
The f irst and the 8econd panels are held together by a f irst 20 coupling device 2 which extends along the edge parts lOd and 20d of respective panels, and a second coupling device 3 which extends along respective edge parts lOe and 20e of said panels .
25 Since the ~.o.lrl in~ devices 2 and 3 are mutually identical, and are h~n~f~ Al ly identical, only the rollrl ~n~ device 3 will be described in detail, with reference to Figure 3.
As will be seen from the drawing, one part 31 of a two-part 30 ~ r' ing device 3 is fastened to the rear side lOb of two mutually opposing edge parts lOd and lOe of the first panel 10. Second parts 32 of the two-part coupling device 3 are fastened to the rear side 20b on two mutually opposing edge parts 20d and 20e of the second panel 20.
The distance b' between the two col~rl~n~ parts 31, 31' associated with the first panel 10 differs from the distance ., . _ .. . . . .
~0 95/33253 1 ~
~7~977~
bl' between the two second coupling parts 32, 32' assoclated with the second panel 20.
In the ill~ LaL~d case, this difference in distance is greater than 10% and less than 60%, normally between 15 ana 30% .
In the case oi the 1 illustrated in Figure 1 and 2, the difference in distance is about 2096.
The distance "c" between the coupling device and the edge 10e' of the first panel 10 is, in practice, between 5 and 30%
of the width "b" of the panel 10.
15 In the illustrated case, the edge 20e' of the second panel 20 terminates just short of the edge lOe', although it may pro~ect beyond said edge 10e' to some extent, which is deter-mined f rom case to case .
20 One part of the two-part coupling device has, in the illus-trated case, the ~orm of a strip which forms a gap 31a, with the gaps for the two parts 31, 31' associated with the first panel 10 ( the l-aL~ panel ) facing towards each other.
25 The second coupling part 32 also has the form of a strip which forms a gap 32a, with the gaps for the two second r~ ~n~T parts 32, 32' associated with the second panel 20 ( the broader panel ) facing away from each other .
30 Respective panels 10 are comprised of plastic sheet and the first and/or the second part of respective coupling devices are comprised of a strip 31b, 32b, which is fastened to the panels with the aid of respective fastener means 31c and 32c.
35 When the panel has a height extension of 2 . 0 m and a width of 0. 7 m and when the width of the rear panel is 2096 greater than the width of the front panel (0.8 m), the panel will ~ 2 189779 conveniently have a thlr~n~cc of from 0.2-1.0 mm.
The panel will preferably have an elastic modulus where E =
2, 000-5, 000 MPa.
By way of comparison, it can be mentioned that PVC has an E-modulus = 3, 200 MPa and a PVC-panel has a thickness of 0 . 5 mm, the panel will have properties that will enable it to be bent or flexed in the manner decreed by the invention.
10 Greater thl rknf~cc-~c and/or higher elasticity moduli may be pref erable .
A "print" on ele:~Llu~L(lLlc paper can be baked in with a hot-laminate-polyester + polyethylene having a thl rknl~cc of 0 . 25 15 mm on the front and the rear sides to form such a panel. ~he base material may then have a thlrkn~cc slightly greater than 0.5 mm and a, ' ln~d E ~ C desired (somewhat stiffer than PVC ) .
20 The fastener means and/or one or both coupling parts of the two-part rnllrl lng device may consist in a double-sided adhesive tape, a VelcroD tape, a p~r~ Lly magnetized strip or some like device.
25 It is particularly preferred that the fastener means is comprised of an elastically resilient material.
According to one preferred ~fll- ~ in this regard, there i9 conveniently used in some applications an adhesive tape 30 which is provided with a double-adhesive plastic foam as the fastening means for one or the other of said coupling parts of respective rs -rl 1 nrJ devices.
~ he first parts and the second parts of the two-part coupling 35 device are comprised of b~n~l~hl ~ strips 31b, 32b, such as plastic strips, wherein the plastic strips have a b~nfl~hl 11 ty or fl~xlhlllty which exceeds the flf~xlhll;ty of the first W0 95133~53 r~ q~
2 1~779 panel 10 or the second panel 20.
In view of the desire to provide dlsplay units that can be easlly assembled and easily dismantled and the re~auirement 5 of using display panels whose stif fness enables the panels to be rolled-up into appropriate tubular shapes, the inven-tion proposes a number of different ~1 c1nn1nsJ p~cc;h;11-ties for readily rhRn~1 ng the cross-sectional shape of the unit, in Rl-rnrrls~n(-e with Figure 2.
A first pocs~h11 ;ty is to give the first and the second display panels lC, 20 the same degree of rigidity, E-modulus, and the same th1 ~kn~cR therewith obtaining a cross-sectional shape essentially corresponding to that shown in Figure 2, 15 particularly when the coupling devices 2, 3 are fitted at the locations shown in Figure 2.
Another FoqR1h; 1 ;ty is to make the first panel 10 more rigid, or stiffer, than the second panel 20.
The change in conf iguration af f orded hereby is shown in Figure 6A to Figure 6C.
A third pnc~;h1lity is for the second panel 20 to be more 25 rigid, or stiffer, than the first panel 10.
By altering the distance between the ~ol~rl ;n~ devices 2, 3, with regard to the second panel 20, for instance, different cross-sectional shapes are obtained, as illustrated in Figure 30 7A to Figure 7C, and a chan~e in cross-sectional shape can also be achieved by positioning the ro~lr1; n~ devices 2 and 3 at ~1ff~rPnt distances from the edge parts lOe' and lOe'.
This is shown in more detail in Figure 8A to Figure 8D.
There is nothing to prevent the coupling device 2 irom being located at a first distance and the coupling device 3 being ~09~/33253 r~lla~7~
,~ ~ 1 8~779 located at a dlfferent distance, l . e. a second distance, from the edge part of a respectlve panel, wherewlth the coupllng devlce 2 may be located closer to or further away from the edge part lOd' than the spaclng of the r~llpl inr devlce 3 ln 5 relatlon to the edge part lOe ', or vlce versa.
As wlll be seen partlcularly from Flgure l, when the dlsplay unlt l is ' 1~, the outwardly faclng surface lOa of the flrst dlsplay panel lO will be slightly concave in a horlzon-lO tal plane, whlle the outwardly faclng surface 20a of thesecond panel 20 wlll be convex with the lower edge surfaces lO', 20' of the panel extending in a flat state between the edge parts lOd', lOe' and rest agalnst a flat supportive surf ace 6 .
In the illustrated case, the outer llmltatlon llnes of the dlsplay panels lO and 20 deflne a Lt:.:Lcllyular surface.
These limitatlon llnes, or ~lefin1n3 llnes, may, of course, 20 have any deslred form, however.
However, the llmltatlon llnes that face towards the support-lve surface 6 shall be conflgured to enable the panels 10 and 20 to be ~U~OL L~:d agalnst the supportlve surface so as to 25 form a stable unit, unless otherwise deslred.
Figure 4 shows the p~ h~ 1~ ty of rolllng-up a dlsmantled dlsplay panel lO and storlng the panel ln lts rolled-up state. In thls case, the base materlal of the panel lO and 30 the coupllng devlces 31, 31 ' applied thereto wlll all be bent to a cyllndrlcal form.
Corr~p~n~l~n~3y, the display panel 20 can be rolled-up to f orm a sllmmer cylinder, and the two cyllnders can then be 35 lnserted one into the other ln a speclally rl~ n~ r~r~ 1 ng or transport tube 7, shown in Flgure 5.

Figure 6 is intended to illustrate and describe more clearly those changes, or deLu~ c-Llons, in the cross-sectional shape of the unit that are achieved when the stiffness of the front panel lû and the stiffness of the rear panel 20 vary, with 5 the rear panel 20 having a width which is 20~6 larger than the width of the front panel 10 and the attachment points of the coupling devices 2, 3 being centered f rom the outer edges at a distance CorrpqFnn~l~n~ to 20% of the width of the front panel .
In the Figure 6A ~ t, the front panel 10 is twice as rigid as the rear panel 20, while in the Figure 6B em. bodi-ment, the front panel 10 and the rear panel 20 have the same stiffness, while in the case of the pmholl1 L shown in 15 Figure 6C, the stiffness, or rigidity, of the front panel 10 is half that of the rear panel 20.
Figure 7 is intended to illustrate the deformation or change in cross-sectional shape, of the unit when the ratio of the 20 distances from the parts of the rl~url in~ devices (the width) on the front panel 10 and the rear panel 20 vary, but when the front panel 10 and the rear panel 20 have mutually the same stiffness and are fastened at the same distance from the edge part.
For instance, Figure 7A illustrates an omhorll L in which the wldth of the rear panel 20 is 10% greater than the width of the front panel, while 7B shows an ~ 1 in which the width of the rear panel 20 is 20% greater than the front 30 panel 10, and Figure 7C shows an embodiment in which the width of the rear panel 20 is 30% greater than the width of the front panel 10.
Figure 8 is intended to describe the changes in shape that 35 derive from the position of the points of attachment of the coupling parts o said coupling device, and also to show the n1f1r~nr.P o_this position with regard to the deformation wo g5133253 r~ . o~
achieved when the two front and rear panels 10, 20 have mutually the same stlffness.
In this regard, Figure 8A illustrates the cross-sectional 5 shape that i8 achieved when the coupling parts are positioned at the uut L ends, although this may result in a somewhat flimsy and less robust construction.
Figure 8B shows the coupling parts attached at a slight 10 distance from the edge ( 596 of the width), at which point the stiffening tension forces begin to take effect in the display panels .
In the case of the Figure 8C illustration, the att~l' -t lS points are placed inwardly from the edge at a distance uuLL~ rl;ns to 20% of the width, such as to produce an arch, which is considered suitable in a number of applica-tions . Figure 8D shows the a L I ~ L points located inwardly of the edge at a distance UULL~ Jl- tl~ n~ to 3096 of the width, 20 although in this case the resultant arch is too large for practical purposes.
Figure 9 is intended to show the pnCR; h1 l; ty of fastening a permanently magnetized strip to the rear side of the front 25 panel edge, with the aid of an adhesive material or magnetic strip .
This enables similar units to be added one to the other.
Figure 9 illustrates two display units con~ LLU~,L~d in 30 accordance with the inventive concept, these units supporting or carrying a single further display panel 30 which lacks "back" stiffening means.
It is also shown that the coupling parts of the co~r l; n~
35 device 2, 3 can be mutually uul-vc~Ly~llL, to provide varying stability in the vertical direction.

Figure 10 is a pt L~;Llve view of the construction shown in Figure 9, using p~ - n.-~.Lly magnetized strips as col~rl 1n~
devices 2, 3 and a similar, edge-related strip 100.
5 Figure 11 is a perspective view of one '-'1 t of an inventive display unit which comprises three mutually identical panels 10, 20 and 30. Figure 12 shows a ciisplay unit having four mutually identical panels 10, 20, 30 and 40, while Figure 13 shows a unit .~ ,LLu~,Llon comprising four panels 10, 20, 30 and 40 with pairs of panels having mutually different ~111 q1nnq.
Figure 14 is a ~:L~eL;LlVe view of a display unit comprising five panels 10, 20, 30, 40 and 50.
It will be seen that as a result of the variation afforded by the different panel configurations and different panel stiffnesses, and also as a result of the various locations at which the coupling devices 2, 3 can be attached, every 20 pnqq1 hl ~ combination given in the present do, t is poq~ hl ~ within the scope of the inventive concept.
Figure 15 is a sectioned side view of first edge parts of two mutually coacting panels, a first panel 10 and a second panel 20, when these panels are Joined to form a unit.
Figure 15 also illustrates how the display surface of the first panel 10 can be made flat, and shows the first coupling part 31 of a two-part coupling device 3 located adJ acent the edge surf ace .
The second part 32 of the two-part coupling device 3 has the form of adhesive tape 32a, whose one edge part 32a' is fastened to the second panel 20 at a distance from the edge surface 201, and whose other edge part 32a" is fastened to 35 a magnetic strip 31a' which is fastened adhesively to the first panel 10, adjacent its edge surface 101.

The edge surface 201 of the second panel 20 is therewith intended to rest against the rear side of the first panel 10, against the magnetic strip 31a ' .
Figures 16 and 17 illustrate an alternative ' ~11 L in which said device i8 formed by virtue of the first cQllrl ln~
part 31 having the form of two pivotally connected magnetic strips 310, 311, of which a first magnetic strip 310 i8 fastened to the first panel ad~acent its edge surface 101, and the second strip 311 is adapted for coaction with a magnetic strip 33a' fastened on the edge surface 201 of the second panel 20.
Figure 17 is intended to show the position that occurs when the first panel 10 coacts with the second panel 20 with the aid of a two-part collr1 ;nS device according to Figure 16, said panels 10, 20 having essentially the same stiffness or rigidity .
The length and the thl rknPcc of the two magnetic strips shall be chosen in relation to the thl~ nPcc and the stlffnPCR of respective panels, so that the first panel 10 will obtain a flat display surface 10 ' .
The magnetic strips 310, 311 and the magnetic strip 33a' have mutually the same cross-section and length and have a polarization such that said strips (311 and 33a' ) will be able to coact with one another in a manner to obtain a precisely located position, as shown in the Figure.
An adhesive tape 312 is provided to hold the magnetic strips 310 and 311 Luut:LIleL and to form a hinge 313 therebetween.
It will be understood that the width of the tape 312 can be adapted so that the edge surface 101 of the first panel 10 will lie in plane with the general extension of the panel 10.
The tape 312 is thus fastened in a manner which will enable WO95l33253 l~lla~
2 I rd 977q ~
it to straighten or lncline the edge surface of the first panel 10.
It will be seen from Figure 17 that the magnetic strip 33a' of the second panel 20 is distanced from the edge 201 such that the tape 312 will counteract any torque that is generat-ed and provide a straight front surface 10 ' .
It will be noted that the magnetic strip 33a' is fastened to the second panel 20 at a distance "a" from the edge surface 201. (See Figure 16. ) The ' -'; 1 shown in Figure 17 has also been supplemented with a further holding device 315 in the form of a magnetic strip. This magnetic strip 315 is able to coact with holding means in the form of a magnetic strip 310 positioned along the edge surface 101 of the first panel 10, and .l ,L~-~L~I,,lTng holding means in the form of a r-S!n~ r strip 310 ' positioned along the ed~e surface 101' of an adjacent panel 10", therewith positioning the two panels in one and the same plane or permitting the panels to be angled in relation to one another.
Figure 18 is a perspective view of one end section of the '~o~ t shown in Figure 17. The reference numeral 315 identifies a magnetic strip which can be rolled-up ana which when in a rolled-up state functions to couple together two separate display units, each having an edge-related magnetic strip, wherein the parts or panels ( 10, 10", 20, 20 ' ) of the unit may also be capable of being rolled-up.
It will be understood in tbis regard that the adhesive tape 312 may not be too thick, since a thick tape is not only stif f and needs to be highly resilient in order to return from a rolled state to a flat state, but also weakens the magnetic attr~ction forces.

5 It will be understood that the invention is not restricted to the illustrated and described exemplifying embodiments thereof, and that 'lflrAtlons can be made wlthin the scope of the inventive concept as deflned in the following Claims.
Another fF~hnll-~l problem is one of rf~ in~ that in order to obtain a simple unit construction, the f irst panel, i . e.
the flat panel, should be provided with an edge-orientated strip, such as a magnetic strip, prior to assembly, and that 5 durlng assembly, the edge part of the second panel should be allowed to support against said magnetic strip and then serve as a support for attachment means and said edge as the second panel is bent.
10 Another te~-hn i ~ problem is one of realizing the signif i -cance of using coupling devices which stand in precise relationship with one another, such as separate magnetized strips having only one single relevant, specific position of mutual attraction.
Another terhn~ l problem is one of providing a rollrl in~
device which is so elastic as to afford requisite compression when rolling-up a panel of lower elasticlty, and corre-sponding P~rAnell~n when unrolling said panel, and vice versa, 20 without the coupling device loosening from the panel.
SOLUTION
With the intention of solving one or more of the aforesaid 25 te~ hnl~l problems, the present invention takes as its starting point an easily ~q~ fl and easily dismantled picture or text display unit which is comprised of at least two sheet-like panels whose outer defining surfaces may be quadratic or rectangular in shape with the exception of the 30 upper edge surfaces and/or side surfacesr when ~udged to be suitable .
,~rrr~r~l~ns~ to the invention, first parts of two-part coupling devices are each fastened ad~acent a respective edge of two 35 mutually opposing edge parts of a first panel, and the second parts of said two-part coupling devices are each f astened ad; acent a respective edge of two mutually opposing edge .. _ . ... _ _ . . . , . .. .. , . . . _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ WO 9S1332S3 r ~ Jq(~ ~
parts of the second panel, wherein the horizontal distance between the courl inS parts associated with the first panel differs from the horizontal distance between the second coupling parts of respective coupling devices associated with the second panel.
According to proposed ' '~ I i that fall within the scope of the inventive concept, each of the first rm-~nl ~n~ parts defines a gap, with the gaps defined by the two coupling parts associated with the first panel facing towards one another .
Each of the second rollrl;n~ parts also defines a gap, with the gaps defined by said two second coupling parts associated with the second panel facing away from each other.
According to the present invention, it is n~ C~ I y for the difference in the between the first coupling parts and the second rol-rl1n~ parts to be greater than 10% and preferably less than 60%, normally between 15 and 30%.
~rcrr~1n~ to one embodiment of the invention, respective picture or teYt-carrying panels have the form of plastic sheets and the first and/or second parts of respective 25 coupling devices have the form of a strip attached to said panels with the aid of a fastener means.
In this regard, the fastener means may have the form of Velcrd5 tape, magnetized strip, double-sided adhesive tape or 30 the like, and the fastener means will preferably be slightly elastic and springy.
According to another P~ho,ll It of the invention, the first and the second coupling parts may have the form of a flPY~hl~

The stif fness of one picture-carrying panel may conveniently be greater than the stiffness of the other panel.
According to the invention, the display unit is structured so that when two picture-carrying panels are brought together and f astened to one another by means of said two-part coupling devices, the outwardly facing surface of one panel 10 will have a slightly concave ~;ulvatule in a defined plane, such as a horizontal plane, and the outwardly facing surface of the other panel will have a convex ~ulvelLul~: with bottom edge surfaces that extend between said edge parts of the two panels so as to support against an underlying supportive 15 surface.
The invention also relates to the sheet-like panels in a dismantled state of the picture or text display unit, with said one or said second parts of respective coupling devices 20 being bc~n~l~hle to a cylinrlr~r~ shape, wherein the height or length of the cylinder thus formed corresponds to the width of respective panels.

2~89779 Further zidv~-lL~Iy~s that are afforded by an inventive picture or text display unit reside in the provision of conditions which enable a flat, or generally flat, display surface to be obtained on the first panel with the aid of an especially 5 configured devLce coacting between the coupling parts of a two-part coupling device, even when the panels are made from a readily h~n~lAhl~ or flf:~lr;hl~ material.

;n~ OF 7~MRl~nTM~NTS NOW
Figure 1 is a perspective view of a picture or text display unit 1 in an a~ state, said unit comprising two sheet-like panels, i.e. a first panel 10 and a second panel 20.
35 The first panel 10 has an outwardly facing surface lOa on which a desired picture or text can be mounted.
.. , .. _ _ _ . . _ _ _ _ _ _ _ _ _ _ _ _ _ ~fo 95l33253 P
~ 218977~
The second panel has an outwardly facing surface 20a onto which a picture or text can be mounted, similar to the surface lOa.
5 The first panel 10 has an inwardly facing surface lOb, and the second panel 20 has an inwardly facing surface 20b.
The first panel 10 has a rectangular surface extension of width "b", coL ~ n~ to 70 cm, and a height "h" corre-qron(l1n~ to 2 m.
The second panel 20 has a width "bl" corr~cp~n~1 n~ to 85 cmand a height "h" corrl~cr~n~lin~ to 2 m, and has also a rectangular surface extension or shape.
Both panels 10, 20 are produced from one and the same material have mutually the same stiffness and ~h1~ n~cc.
The f irst and the 8econd panels are held together by a f irst 20 coupling device 2 which extends along the edge parts lOd and 20d of respective panels, and a second coupling device 3 which extends along respective edge parts lOe and 20e of said panels .
25 Since the ~.o.lrl in~ devices 2 and 3 are mutually identical, and are h~n~f~ Al ly identical, only the rollrl ~n~ device 3 will be described in detail, with reference to Figure 3.
As will be seen from the drawing, one part 31 of a two-part 30 ~ r' ing device 3 is fastened to the rear side lOb of two mutually opposing edge parts lOd and lOe of the first panel 10. Second parts 32 of the two-part coupling device 3 are fastened to the rear side 20b on two mutually opposing edge parts 20d and 20e of the second panel 20.
The distance b' between the two col~rl~n~ parts 31, 31' associated with the first panel 10 differs from the distance ., . _ .. . . . .
~0 95/33253 1 ~
~7~977~
bl' between the two second coupling parts 32, 32' assoclated with the second panel 20.
In the ill~ LaL~d case, this difference in distance is greater than 10% and less than 60%, normally between 15 ana 30% .
In the case oi the 1 illustrated in Figure 1 and 2, the difference in distance is about 2096.
The distance "c" between the coupling device and the edge 10e' of the first panel 10 is, in practice, between 5 and 30%
of the width "b" of the panel 10.
15 In the illustrated case, the edge 20e' of the second panel 20 terminates just short of the edge lOe', although it may pro~ect beyond said edge 10e' to some extent, which is deter-mined f rom case to case .
20 One part of the two-part coupling device has, in the illus-trated case, the ~orm of a strip which forms a gap 31a, with the gaps for the two parts 31, 31' associated with the first panel 10 ( the l-aL~ panel ) facing towards each other.
25 The second coupling part 32 also has the form of a strip which forms a gap 32a, with the gaps for the two second r~ ~n~T parts 32, 32' associated with the second panel 20 ( the broader panel ) facing away from each other .
30 Respective panels 10 are comprised of plastic sheet and the first and/or the second part of respective coupling devices are comprised of a strip 31b, 32b, which is fastened to the panels with the aid of respective fastener means 31c and 32c.
35 When the panel has a height extension of 2 . 0 m and a width of 0. 7 m and when the width of the rear panel is 2096 greater than the width of the front panel (0.8 m), the panel will ~ 2 189779 conveniently have a thlr~n~cc of from 0.2-1.0 mm.
The panel will preferably have an elastic modulus where E =
2, 000-5, 000 MPa.
By way of comparison, it can be mentioned that PVC has an E-modulus = 3, 200 MPa and a PVC-panel has a thickness of 0 . 5 mm, the panel will have properties that will enable it to be bent or flexed in the manner decreed by the invention.
10 Greater thl rknf~cc-~c and/or higher elasticity moduli may be pref erable .
A "print" on ele:~Llu~L(lLlc paper can be baked in with a hot-laminate-polyester + polyethylene having a thl rknl~cc of 0 . 25 15 mm on the front and the rear sides to form such a panel. ~he base material may then have a thlrkn~cc slightly greater than 0.5 mm and a, ' ln~d E ~ C desired (somewhat stiffer than PVC ) .
20 The fastener means and/or one or both coupling parts of the two-part rnllrl lng device may consist in a double-sided adhesive tape, a VelcroD tape, a p~r~ Lly magnetized strip or some like device.
25 It is particularly preferred that the fastener means is comprised of an elastically resilient material.
According to one preferred ~fll- ~ in this regard, there i9 conveniently used in some applications an adhesive tape 30 which is provided with a double-adhesive plastic foam as the fastening means for one or the other of said coupling parts of respective rs -rl 1 nrJ devices.
~ he first parts and the second parts of the two-part coupling 35 device are comprised of b~n~l~hl ~ strips 31b, 32b, such as plastic strips, wherein the plastic strips have a b~nfl~hl 11 ty or fl~xlhlllty which exceeds the flf~xlhll;ty of the first W0 95133~53 r~ q~
2 1~779 panel 10 or the second panel 20.
In view of the desire to provide dlsplay units that can be easlly assembled and easily dismantled and the re~auirement 5 of using display panels whose stif fness enables the panels to be rolled-up into appropriate tubular shapes, the inven-tion proposes a number of different ~1 c1nn1nsJ p~cc;h;11-ties for readily rhRn~1 ng the cross-sectional shape of the unit, in Rl-rnrrls~n(-e with Figure 2.
A first pocs~h11 ;ty is to give the first and the second display panels lC, 20 the same degree of rigidity, E-modulus, and the same th1 ~kn~cR therewith obtaining a cross-sectional shape essentially corresponding to that shown in Figure 2, 15 particularly when the coupling devices 2, 3 are fitted at the locations shown in Figure 2.
Another FoqR1h; 1 ;ty is to make the first panel 10 more rigid, or stiffer, than the second panel 20.
The change in conf iguration af f orded hereby is shown in Figure 6A to Figure 6C.
A third pnc~;h1lity is for the second panel 20 to be more 25 rigid, or stiffer, than the first panel 10.
By altering the distance between the ~ol~rl ;n~ devices 2, 3, with regard to the second panel 20, for instance, different cross-sectional shapes are obtained, as illustrated in Figure 30 7A to Figure 7C, and a chan~e in cross-sectional shape can also be achieved by positioning the ro~lr1; n~ devices 2 and 3 at ~1ff~rPnt distances from the edge parts lOe' and lOe'.
This is shown in more detail in Figure 8A to Figure 8D.
There is nothing to prevent the coupling device 2 irom being located at a first distance and the coupling device 3 being ~09~/33253 r~lla~7~
,~ ~ 1 8~779 located at a dlfferent distance, l . e. a second distance, from the edge part of a respectlve panel, wherewlth the coupllng devlce 2 may be located closer to or further away from the edge part lOd' than the spaclng of the r~llpl inr devlce 3 ln 5 relatlon to the edge part lOe ', or vlce versa.
As wlll be seen partlcularly from Flgure l, when the dlsplay unlt l is ' 1~, the outwardly faclng surface lOa of the flrst dlsplay panel lO will be slightly concave in a horlzon-lO tal plane, whlle the outwardly faclng surface 20a of thesecond panel 20 wlll be convex with the lower edge surfaces lO', 20' of the panel extending in a flat state between the edge parts lOd', lOe' and rest agalnst a flat supportive surf ace 6 .
In the illustrated case, the outer llmltatlon llnes of the dlsplay panels lO and 20 deflne a Lt:.:Lcllyular surface.
These limitatlon llnes, or ~lefin1n3 llnes, may, of course, 20 have any deslred form, however.
However, the llmltatlon llnes that face towards the support-lve surface 6 shall be conflgured to enable the panels 10 and 20 to be ~U~OL L~:d agalnst the supportlve surface so as to 25 form a stable unit, unless otherwise deslred.
Figure 4 shows the p~ h~ 1~ ty of rolllng-up a dlsmantled dlsplay panel lO and storlng the panel ln lts rolled-up state. In thls case, the base materlal of the panel lO and 30 the coupllng devlces 31, 31 ' applied thereto wlll all be bent to a cyllndrlcal form.
Corr~p~n~l~n~3y, the display panel 20 can be rolled-up to f orm a sllmmer cylinder, and the two cyllnders can then be 35 lnserted one into the other ln a speclally rl~ n~ r~r~ 1 ng or transport tube 7, shown in Flgure 5.

Figure 6 is intended to illustrate and describe more clearly those changes, or deLu~ c-Llons, in the cross-sectional shape of the unit that are achieved when the stiffness of the front panel lû and the stiffness of the rear panel 20 vary, with 5 the rear panel 20 having a width which is 20~6 larger than the width of the front panel 10 and the attachment points of the coupling devices 2, 3 being centered f rom the outer edges at a distance CorrpqFnn~l~n~ to 20% of the width of the front panel .
In the Figure 6A ~ t, the front panel 10 is twice as rigid as the rear panel 20, while in the Figure 6B em. bodi-ment, the front panel 10 and the rear panel 20 have the same stiffness, while in the case of the pmholl1 L shown in 15 Figure 6C, the stiffness, or rigidity, of the front panel 10 is half that of the rear panel 20.
Figure 7 is intended to illustrate the deformation or change in cross-sectional shape, of the unit when the ratio of the 20 distances from the parts of the rl~url in~ devices (the width) on the front panel 10 and the rear panel 20 vary, but when the front panel 10 and the rear panel 20 have mutually the same stiffness and are fastened at the same distance from the edge part.
For instance, Figure 7A illustrates an omhorll L in which the wldth of the rear panel 20 is 10% greater than the width of the front panel, while 7B shows an ~ 1 in which the width of the rear panel 20 is 20% greater than the front 30 panel 10, and Figure 7C shows an embodiment in which the width of the rear panel 20 is 30% greater than the width of the front panel 10.
Figure 8 is intended to describe the changes in shape that 35 derive from the position of the points of attachment of the coupling parts o said coupling device, and also to show the n1f1r~nr.P o_this position with regard to the deformation wo g5133253 r~ . o~
achieved when the two front and rear panels 10, 20 have mutually the same stlffness.
In this regard, Figure 8A illustrates the cross-sectional 5 shape that i8 achieved when the coupling parts are positioned at the uut L ends, although this may result in a somewhat flimsy and less robust construction.
Figure 8B shows the coupling parts attached at a slight 10 distance from the edge ( 596 of the width), at which point the stiffening tension forces begin to take effect in the display panels .
In the case of the Figure 8C illustration, the att~l' -t lS points are placed inwardly from the edge at a distance uuLL~ rl;ns to 20% of the width, such as to produce an arch, which is considered suitable in a number of applica-tions . Figure 8D shows the a L I ~ L points located inwardly of the edge at a distance UULL~ Jl- tl~ n~ to 3096 of the width, 20 although in this case the resultant arch is too large for practical purposes.
Figure 9 is intended to show the pnCR; h1 l; ty of fastening a permanently magnetized strip to the rear side of the front 25 panel edge, with the aid of an adhesive material or magnetic strip .
This enables similar units to be added one to the other.
Figure 9 illustrates two display units con~ LLU~,L~d in 30 accordance with the inventive concept, these units supporting or carrying a single further display panel 30 which lacks "back" stiffening means.
It is also shown that the coupling parts of the co~r l; n~
35 device 2, 3 can be mutually uul-vc~Ly~llL, to provide varying stability in the vertical direction.

Figure 10 is a pt L~;Llve view of the construction shown in Figure 9, using p~ - n.-~.Lly magnetized strips as col~rl 1n~
devices 2, 3 and a similar, edge-related strip 100.
5 Figure 11 is a perspective view of one '-'1 t of an inventive display unit which comprises three mutually identical panels 10, 20 and 30. Figure 12 shows a ciisplay unit having four mutually identical panels 10, 20, 30 and 40, while Figure 13 shows a unit .~ ,LLu~,Llon comprising four panels 10, 20, 30 and 40 with pairs of panels having mutually different ~111 q1nnq.
Figure 14 is a ~:L~eL;LlVe view of a display unit comprising five panels 10, 20, 30, 40 and 50.
It will be seen that as a result of the variation afforded by the different panel configurations and different panel stiffnesses, and also as a result of the various locations at which the coupling devices 2, 3 can be attached, every 20 pnqq1 hl ~ combination given in the present do, t is poq~ hl ~ within the scope of the inventive concept.
Figure 15 is a sectioned side view of first edge parts of two mutually coacting panels, a first panel 10 and a second panel 20, when these panels are Joined to form a unit.
Figure 15 also illustrates how the display surface of the first panel 10 can be made flat, and shows the first coupling part 31 of a two-part coupling device 3 located adJ acent the edge surf ace .
The second part 32 of the two-part coupling device 3 has the form of adhesive tape 32a, whose one edge part 32a' is fastened to the second panel 20 at a distance from the edge surface 201, and whose other edge part 32a" is fastened to 35 a magnetic strip 31a' which is fastened adhesively to the first panel 10, adjacent its edge surface 101.

The edge surface 201 of the second panel 20 is therewith intended to rest against the rear side of the first panel 10, against the magnetic strip 31a ' .
Figures 16 and 17 illustrate an alternative ' ~11 L in which said device i8 formed by virtue of the first cQllrl ln~
part 31 having the form of two pivotally connected magnetic strips 310, 311, of which a first magnetic strip 310 i8 fastened to the first panel ad~acent its edge surface 101, and the second strip 311 is adapted for coaction with a magnetic strip 33a' fastened on the edge surface 201 of the second panel 20.
Figure 17 is intended to show the position that occurs when the first panel 10 coacts with the second panel 20 with the aid of a two-part collr1 ;nS device according to Figure 16, said panels 10, 20 having essentially the same stiffness or rigidity .
The length and the thl rknPcc of the two magnetic strips shall be chosen in relation to the thl~ nPcc and the stlffnPCR of respective panels, so that the first panel 10 will obtain a flat display surface 10 ' .
The magnetic strips 310, 311 and the magnetic strip 33a' have mutually the same cross-section and length and have a polarization such that said strips (311 and 33a' ) will be able to coact with one another in a manner to obtain a precisely located position, as shown in the Figure.
An adhesive tape 312 is provided to hold the magnetic strips 310 and 311 Luut:LIleL and to form a hinge 313 therebetween.
It will be understood that the width of the tape 312 can be adapted so that the edge surface 101 of the first panel 10 will lie in plane with the general extension of the panel 10.
The tape 312 is thus fastened in a manner which will enable WO95l33253 l~lla~
2 I rd 977q ~
it to straighten or lncline the edge surface of the first panel 10.
It will be seen from Figure 17 that the magnetic strip 33a' of the second panel 20 is distanced from the edge 201 such that the tape 312 will counteract any torque that is generat-ed and provide a straight front surface 10 ' .
It will be noted that the magnetic strip 33a' is fastened to the second panel 20 at a distance "a" from the edge surface 201. (See Figure 16. ) The ' -'; 1 shown in Figure 17 has also been supplemented with a further holding device 315 in the form of a magnetic strip. This magnetic strip 315 is able to coact with holding means in the form of a magnetic strip 310 positioned along the edge surface 101 of the first panel 10, and .l ,L~-~L~I,,lTng holding means in the form of a r-S!n~ r strip 310 ' positioned along the ed~e surface 101' of an adjacent panel 10", therewith positioning the two panels in one and the same plane or permitting the panels to be angled in relation to one another.
Figure 18 is a perspective view of one end section of the '~o~ t shown in Figure 17. The reference numeral 315 identifies a magnetic strip which can be rolled-up ana which when in a rolled-up state functions to couple together two separate display units, each having an edge-related magnetic strip, wherein the parts or panels ( 10, 10", 20, 20 ' ) of the unit may also be capable of being rolled-up.
It will be understood in tbis regard that the adhesive tape 312 may not be too thick, since a thick tape is not only stif f and needs to be highly resilient in order to return from a rolled state to a flat state, but also weakens the magnetic attr~ction forces.
