Description
W O 97/12352 PCTA~L96/00325 Title: Presentation assembly and material web roll int~n~
_or such presentation Ac~mhly.
The present inv~n~;on relates to a presentation assembly comprising a housing and a material web which is capable o~
being written on and which is wound into a roll, the roll being accnmm~Ated in the housing so as to be rotatable about the longitll~;nAl axis thereof, the housing being provided with a dispensing slot through which the material web cApAhle of being written on is dispensed _rom the housing when the roll is being unwound.
Such an assembly is ~ rl osed in the Boyd application WO 94/2S294. In this application, the roll is ~ormed by a web o~ plastic film having an electrostatic ch~ge. The presentation asse~mbly described by Boyd is in itsel~
particularly convenient, h~Allce it provides the possibility o~ _orming presentation sheets o_ di~ferent sizes cnming ~rom lS a plastic ~ilm web roll, which sheets, as a result o~ the electrostatic ch~se o~ the plastic ~ilm web roll, can readily be stuck to a sur~ace elsewhere, such as ~or instance a wall, a window or a door.
The St~n~nuse patent US-A-5,010,671 discloses a writing pad with electrostatically charged sheets. C~mrA~ed with the Boyd proposal, such a pad-like construction is di~~icult to handle, because the user should handle a relatively large pad.
Moroever, in each case, an entire sheet o_ material is used, even i~ only one single piece o~ information is taken down.
This is a waste o~ material. Also, it has appeared that i~
such pads are stored _or a longer period, the electrostatic charge leaks away and the adhesive properties decrease considerably. secause the material is statically charged, this attracts dust and b~C~m~s dirty during storage.
Inspite of the m~ny advantages that Boyd~s proposal has over Ston~h~usels proposal, there are nevertheless signi~icant drAwh~cks inherent in Boyd's proposal which are also inherent in Stonehouse's proposal. Tt is in particular these drAw~A~ks W O 97/123S2 PCT~NL96/00325 that have stood in the way o~ commercial success of the known devices.
The invention particularly resides in the recognition of this problem.
Strangely enough, both the Boyd publication and the Stonehouse publication only mention a film on which the writing is erasable. Both Boyd and Ston~h~use have halted bet~cen ~w~ ~pi~L ~ ons, ViZ . on the one hand the use o_ a film which is thrown away after use, and on the other the use o~ a ~ilm which can be reused each time, owing to the er~c~h;l;ty thereof. Apparently, in this line of business, the prejudice exists that the user wants an erasable film.
The present inventor has had the insight that most users pre~er a wrlting sur~ace which, as far as the writing properties and the surface structure are concerned, r~m~ n~.C
one of paper as much as possible. Secret tests among potential users have conf;rm~ this insight.
Hence, the presentation assembly according to the invention is characterized in that the material web is provided with at least one relatively rough main sur~ace, so that the writing thereon c~nnot be erased, and with means whereby a part of the material web capable of being written on can be stuck ~lat to a base.
To the user, it is much more agreeable if the material web is of non-erasable design. After the material web has been cut loose, securement o~ the material web part to another sur~ace involves far less chance of the written text being wiped out and o~ stain formation on the user's clothes and hands. Moreover, the material web can easily be rolled up or un_olded and stored without causing the text to be lost. In addition, because o~ the relatively rough sur~ace, the material web is mat. Hence, light f~ll; ng on the material web is not at the expense of the legibility and the material web sur~ace is also suitable ~or projection o~, for instance, ov~h~l sheets and slides. In this connection, one may for instance think of the projection of diagrams to be ~illed in, surveys, graphs and the like. Moreover, the relatively rough , W O 97/12352 PCT~NL96/00325 or matted surface permits the material web to be written on with more types of markers and to be preprinted more properly.
Further, the relatively rough sur~ace results in a better adhesion to all sorts of surfaces, owing to the greater unevenness. An additional advantage to the producer of the ~ material web is that in the case of a non-erasable material web, the user will take a new material web part much sooner, which is favorable for commercial reasons. Compared with the known ~lip-over with a pad o~ paper sheets, the presentation assembly according to the invention o~ers the enormous advantage that it can be o~ a particularly compact design, because the material web is disposed as a roll. Obviously, this aspect was known per se ~rom Boyd; however, the writing sur~ace thereof did not have the desired structure, as a consequence o~ which Boyd's presentation assembly has never become a success. With the proposal according to the present invention, a highly compact presentation assembly is provided which o~ers a writing surface o~ excellent properties.
In accordance with a further elaboration of the invention, the markable material web is ~ormed by a paper web, and the means where~y a paper web part can be stuck ~lat to a base are ~ormed by a reusable adhesive provided on at least one main sur~ace of the paper web.
A presentation assembly of such design o~ers the advantage that the roll can be o~ a relatively cheap design while the quality of the writing surface is very good. After all, by most users, paper is considered the most desirable sur~ace. In order to keep the rolled-up paper ~lat a~ter unw; n~; ng the roll, and to enable securement thereo~ to all kinds oE surfaces, the reusable adhesive is provided.
Pre~erably, the reusable adhesive is provided on the longitll~;n~l edges o~ the paper web. The reusable adhesive can ~or instance be the glue that is also used ~or the yellow Post-itT2~ notes by 3M, known ~rom practice.
In accordance with an alternative ~urther elaboration o~
the invention, the material web is manu~actured ~rom a plastic ~ilm web, and the means whereby a plastic ~ilm web part can be W O 97/12352 PCT~NL~G/'~ ?2 stuck flat to a base are ~ormed by an electrostatic charge applied to the plastic film web.
The advantage of such an electrostatically charged plastic ~ilm is that it a & eres particularly easily to all kinds o~ surfaces and that the t~n~ncy o~ the ~ilm to curl up is m;nim~ed. Owing to the relatively rough sur~ace o~ the ~ilm, the advantages described in detail hereinabove are obt~;n~. As a particular advantage o~ the plastic ~ilm, it can ~urther be mentioned that the relatively rough sur~ace yields a writing sur~ace which optimally r~;n~c the user thereo~ o~ paper.
In accordance with a ~urther elaboration o~ the invention, the sur~ace on the other side o~ the relatively rough sur~ace of the material web can be relatively smooth, so that the writing thereon is ;n~ erasable. In the particular case where a user does temporarily need a writing sur~ace ~rom which the writing is erasable, the roll can readily be reversed, so that the smooth, erasable sur~ace ~aces the user In accordance with a ~urther elaboration o~ the invention, it is also possible that both sur~aces o~ the plastic ~ilm web are provided with a relatively rough sur~ace, so that on both sur~aces, the writing thereon is not erasable.
I~ the material web is a plastic ~ilm web, in order to ~urther strengthen the user's associations with paper, it is particularly ~avorable i~ the plastic ~ilm web is nontransparent. For this purpose, the plastic ~ilm web can ~or instance be o~ a white or colored design.
However, ~or some applications, it is ~avorable i~ the plastic ~ilm web is transparent One may ~or instance think o~
uses where a particular ~igure underlying the transparent material web is to be traced.
Another drawback o~ the Boyd proposal is ~ormed by the construction o~ the blade guide which also constitutes a pressure strip. A~ter a sheet has been cut ~rom the material web, the material web should in each case be ~ed through nn~ne~th the pressure strip again, which is laborious and causes a great loss of time.
W O 97/12352 PCTANL9~ 3~
In order to overcome this drawback, in accordance with a ~urther elaboration o~ the invention, the presentation assembly is characterized in that at an end upstream of the dispensing slot, viewed in a material web dispensing direction, the housing comprises a cutting blade holder guide to which a cutting blade holder is slidably connected, the cutting blade holder ext~n~;ng over the dispensing slot, and that at an end downstream o~ the dispensing slot, viewed in the material web dispensing direction, the housing comprises a cutting blade intended ~or cutting o~ a sheet ~rom the material web. Because the guide o~ the blade is located at the upstream end o~ the dispensing slot and there is no pressure strip, the material web, a~ter a sheet has been cut o~, can readily be ~urther unrolled and stuck to the base by means o~
the electrostatic charge or the reusable adhesive.
In order to have the cutting operation proceed without any problems, in accordance with a ~urther elaboration of the invention, the presentation assembly is characterized by a hardened strip located at the downstream end o~ the dispensing slot, viewed in the material web dispensing direction, and at a shortest possible distance there~rom, the hardened strip serving as cutting sur~ace ~or the cutting blade. Because the cutting operation can take place at a shortest possible distance ~rom the dispensing slot, the chance o~ the material web tucking up as a consequence o~ the cutting operation is m;n;m; ~ed. In fact, owing to this construction, the dispensing slot has the action of a pressure strip. In order to ~nh~nce this action still further, in accordance with a ~urther elaboration o~ the invention, the presentation assembly is characterized in that the dispensing slot comprises material web flattening means, such as a brush or a ~lexible ~lap.
Apart from the fact that the pressure strip action of the dispensing slot is ~nh~nced thereby, the housing is moreover less accessible to dust, as a result o~ which, in the case where the material web is an electrostatic plastic ~ilm web, the electrostatic charge o~ the plastic ~ilm web is better maint~; n~ and the user is provided with a cleaner writing sur~ace.
To m;n;m;~e shi~ting of the material web roll in the housing during cutting, which shifting can affect the cutting operation in a negative sense, the housing comprises, at two end ~aces thereo~, frustro-conical, rotatably bearing-mounted roll holders, at least one of which is resiliently slidable in the direction of the longit~; n~ 1 axis o~ the roll, allowing the roll to be clamped between the two roll holders with pre-c~ ession. Owing to this mAnn~ of bearing-mounting the roll in the housing, a stable positioning o~ the material web roll is obt~; n~ ~
The housing preferably c~ ises w; n~; ng means which are engageable rrom the outside o~ the housing and whereby the roll can be wound and unwound. Such w; n~; ng means can for instance be constructed as a crank or a t~-~n; ng ]mob. By means of the w;n~;n~ means, a partly unwound material web can be wound on the roll again and thus be safely stored in the housing.

In order to overcome this drawback, in accordance with a ~urther elaboration o~ the invention, the presentation assembly is characterized in that at an end upstream of the dispensing slot, viewed in a material web dispensing direction, the housing comprises a cutting blade holder guide to which a cutting blade holder is slidably connected, the cutting blade holder ext~n~;ng over the dispensing slot, and that at an end downstream o~ the dispensing slot, viewed in the material web dispensing direction, the housing comprises a cutting blade intended ~or cutting o~ a sheet ~rom the material web.

Owing to this mAnn~ of bearing-mounting the roll in the housing, a stable positioning o~ the material web roll is obt~; n~ ~
The housing preferably c~ ises w; n~; ng means which are engageable rrom the outside o~ the housing and whereby the roll can be wound and unwound. Such w; n~; ng means can for instance be constructed as a crank or a t~-~n; ng ]mob. By means of the w;n~;n~ means, a partly unwound material web can be wound on the roll again and thus be safely stored in the housing.
2~ The housing of the presentation assembly according to the invention can comprise ~asteners ~or att~rhmrnt to a board or plate-shaped part.
In order to effect that the two surfaces of the material web can easily be written on without the material web roll having to be l~llvved ~rom the housing, the att~rhm~nt can be of such design that the housing can be provided on the plate-shaped part in two positions, with the dispensing slot always being located on the same side o~ the plate-shaped part, so that the ma~erial web in a ~irst position can be written on on one sur~ace thereo~, and in a second position can be written on on the other sur~ace thereor.
In accordance with a Iurther elaboration o~ the invention, an exemplary embodiment o~ the presentation assembly according to the invention which is particularly simple to transport is charac~erized by a stretrh; ng screen, which in a irst condition is rolled up and rorms a compact unit together with the housing, and which in a second W O 97/12352 PCT~L96/00325 condition is unrolled and stretched taut, so that it can serve as a base for an unwound material web part to be written on.
An alternative embodiment of a presentation assembly which is easy to transport is characterized by a plate-shaped part which in a ~irst condition is collapsed and forms a compact unit together with the housing, and which in a second condition is unfolded so that it can serve as base for an unwound material web part to be written on.
In order to further facilitate transportation, in accordance with a further elaboration of the invention, it is particularly favorable if the presentation assembly comprises a collapsible supporting frame which in a collapsed condition ~orms a compact unit with the housing.
It is understood that the presence of a handgrip even further contributes to a simpler transportation of the collapsed unit.
The housing of the presentation assembly can for instance be manufactured in an injection-molding process or by means of extrusion. In the latter case, a part o~ a desired length is sawn from an extrusion section and provided with two end stops which also serve as roll bearing. In this m~nn~, a number of presentation assemblies of different lengths can be manufactured in an economical m~nn~
The invention also relates to a material web rol evidently intended for a presentation assembly as described hereinabove, at least one surface of the material web being relatively rough, so that the writing thereon is not erasable, and the material web is provided with means whereby a material web part capable o~ being written on can be stuck ~lat to a base.
Hereina~ter, the invention will be ~urther explained with reference to an exemplary embodiment shown in the accompanying drawings, wherein:
Fig. 1 shows the different parts o~ the presentation assembly according to the invention;
W O 97/12352 PCTANL96~'Cr32 Fig. 2 shows the plate-shaped part according to Fig. 1, rolled up into a cont~;n~ ~or cont~; n; ng the other parts o~
the presentation assembly;

Fig. 5 shows a ~ront view o~ an alternative embodiment o~
the presentation assembly according to the invention; and Fig. 6 shows a rear view o~ the exemplary em.bodiment shown in Fig. 5.
The presentation assembly shown in Fig. 1 consists o~ a plate-shaped part 1, built up o~ a number o~ l~m; n~tions which are coupled together and are slightly displaceable relative to each other. A presentation assembly 2 is present which is shown in more detail in Fig. 3, in cross section. By 3, a supporting ~rame is indicated consisting o~ two legs connected by pivotable connecting arms 4. The legs consist o~ leg parts 5 and 6, and the leg part 5 can be received within the leg part 6.
As Fiss. 2 and 3 ~mon~trate~ a detach~hle handgrip 15 is present, which also serves to ~asten cont~;n~ 12 to a board 21. By 7, an attachment receiving member is indicated. In this m~nn~, a complete, optionally mobile presentation assembly is provided.
On the other hand, a~ter use, it is possible to detach these parts ~rom the supporting ~rame 3 again and to collapse the supporting ~rame 3 by both moving the legs together and telescopins them. Thus, a whole is obt~;ne~ which is su~iciently compact ~or being accommodated, together with the presentation sheet assembly 2, in the plate-shaped part 1, rolled up into a tube. This is shown in Fig. 2. The handgrip 15 is att~h~ to the receiving members 22 o~ plate-shaped part 1.
In Fig. 3, the presentation sheet assembly 2 is shown.
This assemb;y consists o~ a housing, indicated by 12, wherein a roll 10 oI plastic ~ilm material 11 is accommodated whose W O 97/12352 PCT~NL96/00325 film is electrostatically charged. The housing can be opened in a simple m~nn~, allowing the roll 10 to be reversed or changed while the presentation assembly is in the operative position, after which it is directly ready for use again, without super_luous operations. It is understood that for '' this, it is also possible to choose a paper web, wound into a roll, which web has been provided with means whereby a paper web part can be stuck ~lat to a base. Reusable adhesive as is for instance used for Post-it~ would be suitable for this. The housing 12 comprises a dispensing slot 13. There is also provided a cutting blade 14, which is operative adjacent the dispensing slot 13. The cutting blade 14 can be moved forward and bac~ward for the purpose of cutting off part 11 from the plastic film web. In Fig. 3 it is clearly visible that the guide 23 of the cutting blade holder 24 of the cutting blade 14 is located at the upstream end of the dispensing slot 13 and that the cutting blade 14 is located at the downstream end of the dispensing slot 13. The cutting blade holder 24 extends transversely over the dispensing slot 13 In the exemplary embodiment shown, the blade 14 operates on a hardened cutting strip 25 against which the blade 14 is pressed during cutting However, in accor~nce with an alternative elaboration of the invention, it is very well possible that instead of the cutting strip 25, a groove is provided wherein the blade 14 operates. With such a construction, the risk o~ the film or paper 11 tuc~ing up during cutting is m;n;mized When an electrostatically charged plastic film is used for the material web, this film pre_erably has a thickness ranging bet~een 30 and 60 ~m, and more in particular a thlc~ess c~ abcu~ 35 ~m, an~ ls ~referably ~ whlte fl~m.. It has appeared that with the construction here shown, the electrostatic charge of the film material is maint~;n~. This electrostatic charge is important for enabling a sheet of film 11, a_ter the sheet 11 in question has been written on, to be _ixed on a wall or the like without necessitating separate adhesive means. Obviously, the electrostatic charge is also W O 97/12352 PCT~L9C~'~D-important ~or keeping the ~ilm web, rolled up during a longer time, in a ~lat position when it is being written on.
Fig. 4 illustrates a ~urther embodiment o~ the invention.
The presentation assembly is mounted on a leg consisting o~
telescoping leg parts 8,9. Such a leg can ~or intance be secured to a wall by means o~, ~or instance, suction cups or the like, and sheet material can be unrolled there~rom laterally in accordance with the invention.
Figs. 5 and 6 show an alternative embodiment o~ the presentation assembly according to the invention, wherein the collapsible plate part 1 has been replaced by a stretching screen 26. In a Eirst condition, the stret~-hi ng screen 26 is rolled up and ~orms a c~m~ct unit together with the housing, and in a second condition it is unrolled and stretched taut, so that it can serve as a base ~or an unwound part o~ plastic ~ilm web or paper web to be written on. For the purpose o~
stretching taut, the screen 26 is tightened by a spring not shown, and can be unrolled to di~erent OE tents by means o~
the toggle link assembly 27 shown in Fig. 6 A presentation assembly o~ such design is o~ a light construction and easy to transport.
The plastic ~ilm web can ~or instance be a ~ilm o~
polypropylene, polyester or vinyl. It is understood that these materials are mentioned as an example only and that other film materials or mixtures o~ di~ferent types o~ ~ilm material can also be suitable. As indicated hereinabove, a paper web may also serve as material to be written on.
It is essential that ~or the presentation assembly according to the invention, the material web has at least one relatively rough surrace, so that the writing thereon is not erasable, and ~or the sake or the compactness o~ the presentation assembly, the material is disposed as a roll and comprises means whereby the material, inclined to roll up, can be stuck ~lat to a base, while the material web r~m; n~ the user o~ paper as much as possibie Although the invention has hereinabove been described with re~erence to a pre~erred embodiment, it should be CA 02232062 l998-03-l3 W O 97/12352 PCT~NL96/00325 understood that numerous modi~ications can be made thereto without departing ~rom the scope o~ the present application.
In order to effect that the two surfaces of the material web can easily be written on without the material web roll having to be l~llvved ~rom the housing, the att~rhm~nt can be of such design that the housing can be provided on the plate-shaped part in two positions, with the dispensing slot always being located on the same side o~ the plate-shaped part, so that the ma~erial web in a ~irst position can be written on on one sur~ace thereo~, and in a second position can be written on on the other sur~ace thereor.
In accordance with a Iurther elaboration o~ the invention, an exemplary embodiment o~ the presentation assembly according to the invention which is particularly simple to transport is charac~erized by a stretrh; ng screen, which in a irst condition is rolled up and rorms a compact unit together with the housing, and which in a second W O 97/12352 PCT~L96/00325 condition is unrolled and stretched taut, so that it can serve as a base for an unwound material web part to be written on.
An alternative embodiment of a presentation assembly which is easy to transport is characterized by a plate-shaped part which in a ~irst condition is collapsed and forms a compact unit together with the housing, and which in a second condition is unfolded so that it can serve as base for an unwound material web part to be written on.
In order to further facilitate transportation, in accordance with a further elaboration of the invention, it is particularly favorable if the presentation assembly comprises a collapsible supporting frame which in a collapsed condition ~orms a compact unit with the housing.
It is understood that the presence of a handgrip even further contributes to a simpler transportation of the collapsed unit.
The housing of the presentation assembly can for instance be manufactured in an injection-molding process or by means of extrusion. In the latter case, a part o~ a desired length is sawn from an extrusion section and provided with two end stops which also serve as roll bearing. In this m~nn~, a number of presentation assemblies of different lengths can be manufactured in an economical m~nn~
The invention also relates to a material web rol evidently intended for a presentation assembly as described hereinabove, at least one surface of the material web being relatively rough, so that the writing thereon is not erasable, and the material web is provided with means whereby a material web part capable o~ being written on can be stuck ~lat to a base.
Hereina~ter, the invention will be ~urther explained with reference to an exemplary embodiment shown in the accompanying drawings, wherein:
Fig. 1 shows the different parts o~ the presentation assembly according to the invention;
W O 97/12352 PCTANL96~'Cr32 Fig. 2 shows the plate-shaped part according to Fig. 1, rolled up into a cont~;n~ ~or cont~; n; ng the other parts o~
the presentation assembly;
Fig. 3 shows the presentation assembly according to the invention in cross section;
Fig. 4 shows a ~urther em.bodiment o~ the presentation assembly according to the invention;
Fig. 5 shows a ~ront view o~ an alternative embodiment o~
the presentation assembly according to the invention; and Fig. 6 shows a rear view o~ the exemplary em.bodiment shown in Fig. 5.
The presentation assembly shown in Fig. 1 consists o~ a plate-shaped part 1, built up o~ a number o~ l~m; n~tions which are coupled together and are slightly displaceable relative to each other. A presentation assembly 2 is present which is shown in more detail in Fig. 3, in cross section. By 3, a supporting ~rame is indicated consisting o~ two legs connected by pivotable connecting arms 4. The legs consist o~ leg parts 5 and 6, and the leg part 5 can be received within the leg part 6.
As Fiss. 2 and 3 ~mon~trate~ a detach~hle handgrip 15 is present, which also serves to ~asten cont~;n~ 12 to a board 21. By 7, an attachment receiving member is indicated. In this m~nn~, a complete, optionally mobile presentation assembly is provided.
On the other hand, a~ter use, it is possible to detach these parts ~rom the supporting ~rame 3 again and to collapse the supporting ~rame 3 by both moving the legs together and telescopins them. Thus, a whole is obt~;ne~ which is su~iciently compact ~or being accommodated, together with the presentation sheet assembly 2, in the plate-shaped part 1, rolled up into a tube. This is shown in Fig. 2. The handgrip 15 is att~h~ to the receiving members 22 o~ plate-shaped part 1.
In Fig. 3, the presentation sheet assembly 2 is shown.
This assemb;y consists o~ a housing, indicated by 12, wherein a roll 10 oI plastic ~ilm material 11 is accommodated whose W O 97/12352 PCT~NL96/00325 film is electrostatically charged. The housing can be opened in a simple m~nn~, allowing the roll 10 to be reversed or changed while the presentation assembly is in the operative position, after which it is directly ready for use again, without super_luous operations. It is understood that for '' this, it is also possible to choose a paper web, wound into a roll, which web has been provided with means whereby a paper web part can be stuck ~lat to a base. Reusable adhesive as is for instance used for Post-it~ would be suitable for this. The housing 12 comprises a dispensing slot 13. There is also provided a cutting blade 14, which is operative adjacent the dispensing slot 13. The cutting blade 14 can be moved forward and bac~ward for the purpose of cutting off part 11 from the plastic film web. In Fig. 3 it is clearly visible that the guide 23 of the cutting blade holder 24 of the cutting blade 14 is located at the upstream end of the dispensing slot 13 and that the cutting blade 14 is located at the downstream end of the dispensing slot 13. The cutting blade holder 24 extends transversely over the dispensing slot 13 In the exemplary embodiment shown, the blade 14 operates on a hardened cutting strip 25 against which the blade 14 is pressed during cutting However, in accor~nce with an alternative elaboration of the invention, it is very well possible that instead of the cutting strip 25, a groove is provided wherein the blade 14 operates. With such a construction, the risk o~ the film or paper 11 tuc~ing up during cutting is m;n;mized When an electrostatically charged plastic film is used for the material web, this film pre_erably has a thickness ranging bet~een 30 and 60 ~m, and more in particular a thlc~ess c~ abcu~ 35 ~m, an~ ls ~referably ~ whlte fl~m.. It has appeared that with the construction here shown, the electrostatic charge of the film material is maint~;n~. This electrostatic charge is important for enabling a sheet of film 11, a_ter the sheet 11 in question has been written on, to be _ixed on a wall or the like without necessitating separate adhesive means. Obviously, the electrostatic charge is also W O 97/12352 PCT~L9C~'~D-important ~or keeping the ~ilm web, rolled up during a longer time, in a ~lat position when it is being written on.
Fig. 4 illustrates a ~urther embodiment o~ the invention.
The presentation assembly is mounted on a leg consisting o~
telescoping leg parts 8,9. Such a leg can ~or intance be secured to a wall by means o~, ~or instance, suction cups or the like, and sheet material can be unrolled there~rom laterally in accordance with the invention.
Figs. 5 and 6 show an alternative embodiment o~ the presentation assembly according to the invention, wherein the collapsible plate part 1 has been replaced by a stretching screen 26. In a Eirst condition, the stret~-hi ng screen 26 is rolled up and ~orms a c~m~ct unit together with the housing, and in a second condition it is unrolled and stretched taut, so that it can serve as a base ~or an unwound part o~ plastic ~ilm web or paper web to be written on. For the purpose o~
stretching taut, the screen 26 is tightened by a spring not shown, and can be unrolled to di~erent OE tents by means o~
the toggle link assembly 27 shown in Fig. 6 A presentation assembly o~ such design is o~ a light construction and easy to transport.
The plastic ~ilm web can ~or instance be a ~ilm o~
polypropylene, polyester or vinyl. It is understood that these materials are mentioned as an example only and that other film materials or mixtures o~ di~ferent types o~ ~ilm material can also be suitable. As indicated hereinabove, a paper web may also serve as material to be written on.
It is essential that ~or the presentation assembly according to the invention, the material web has at least one relatively rough surrace, so that the writing thereon is not erasable, and ~or the sake or the compactness o~ the presentation assembly, the material is disposed as a roll and comprises means whereby the material, inclined to roll up, can be stuck ~lat to a base, while the material web r~m; n~ the user o~ paper as much as possibie Although the invention has hereinabove been described with re~erence to a pre~erred embodiment, it should be CA 02232062 l998-03-l3 W O 97/12352 PCT~NL96/00325 understood that numerous modi~ications can be made thereto without departing ~rom the scope o~ the present application.
