Definitions

  • the present invention relates to a presentation assembly comprising a housing and a material web which is capable of being written on and which is wound into a roll, the roll being accommodated in the housing so as to be rotatable about the longitudinal axis thereof, the housing being provided with a dispensing slot through which the material web capable of being written on is dispensed from the housing when the roll is being unwound.
  • the roll is formed by a web of plastic film having an electrostatic charge.
  • the presentation assembly described by Boyd is in itself particularly convenient, because it provides the possibility of forming presentation sheets of different sizes coming from a plastic film web roll, which sheets, as a result of the electrostatic charge of the plastic film web roll, can readily be stuck to a surface elsewhere, such as for instance a wall, a window or a door.
  • the Stonehouse patent US-A-5,010,671 discloses a writing pad with electrostatically charged sheets. Compared with the Boyd proposal, such a pad-like construction is difficult to handle, because the user should handle a relatively large pad. Moroever, in each case, an entire sheet of material is used, even if only one single piece of information is taken down. This is a waste of material. Also, it has appeared that if such pads are stored for a longer period, the electrostatic charge leaks away and the adhesive properties decrease considerably. Because the material is statically charged, this attracts dust and becomes dirty during storage.
  • the invention particularly resides in the recognition of this problem.
  • the present inventor has had the insight that most users prefer a writing surface which, as far as the writing properties and the surface structure are concerned, reminds one of paper as much as possible. Secret tests among potential users have confirmed this insight.
  • the presentation assembly according to the invention is characterized in that the material web is provided with at least one relatively rough main surface, so that the writing thereon cannot be erased, and with means whereby a part of the material web capable of being written on can be stuck flat to a base.
  • the material web is of non-erasable design. After the material web has been cut loose, securement of the material web part to another surface involves far less chance of the written text being wiped out and of stain formation on the user's clothes and hands. Moreover, the material web can easily be rolled up or unfolded and stored without causing the text to be lost. In addition, because of the relatively rough surface, the material web is mat. Hence, light falling on the material web is not at the expense of the legibility and the material web surface is also suitable for projection of, for instance, overhead sheets and slides. In this connection, one may for instance think of the projection of diagrams to be filled in, surveys, graphs and the like.
  • the relatively rough 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 surface 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.
  • the presentation assembly according to the invention offers the enormous advantage that it can be of a particularly compact design, because the material web is disposed as a roll.
  • the markable material web is formed by a paper web
  • the means whereby a paper web part can be stuck flat to a base are formed by a reusable adhesive provided on at least one main surface of the paper web.
  • a presentation assembly of such design offers the advantage that the roll can be of a relatively cheap design while the quality of the writing surface is very good.
  • paper is considered the most desirable surface.
  • the reusable adhesive is provided.
  • the reusable adhesive is provided on the longitudinal edges of the paper web.
  • the reusable adhesive can for instance be the glue that is also used for the yellow Post-itTM notes by 3M, known from practice.
  • the material web is manufactured from a plastic film web, and the means whereby a plastic film web part can be stuck flat to a base are formed by an electrostatic charge applied to the plastic film web.
  • the surface on the other side of the relatively rough surface of the material web can be relatively smooth, so that the writing thereon is indeed erasable.
  • the roll can readily be reversed, so that the smooth, erasable surface faces the user.
  • both surfaces of the plastic film web are provided with a relatively rough surface, so that on both surfaces, the writing thereon is not erasable.
  • the material web is a plastic film web
  • the plastic film web in order to further strengthen the user's associations with paper, it is particularly favorable if the plastic film web is nontransparent.
  • the plastic film web can for instance be of a white or colored design.
  • plastic film web is transparent.
  • 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 extending over the dispensing slot, and that at an end downstream of the dispensing slot, viewed in the material web dispensing direction, the housing comprises a cutting blade intended for cutting off a sheet from the material web. Because the guide of the blade is located at the upstream end of the dispensing slot and there is no pressure strip, the material web, after a sheet has been cut off, can readily be further unrolled and stuck to the base by means of the electrostatic charge or the reusable adhesive.
  • the presentation assembly is characterized by a hardened strip located at the downstream end of the dispensing slot, viewed in the material web dispensing direction, and at a shortest possible distance therefrom, the hardened strip serving as cutting surface for the cutting blade. Because the cutting operation can take place at a shortest possible distance from the dispensing slot, the chance of the material web tucking up as a consequence of the cutting operation is minimized. In fact, owing to this construction, the dispensing slot has the action of a pressure strip.
  • the presentation assembly is characterized in that the dispensing slot comprises material web flattening means, such as a brush or a flexible flap.
  • material web flattening means such as a brush or a flexible flap.
  • the housing comprises, at two end faces thereof, frustro-conical, rotatably bearing-mounted roll holders, at least one of which is resiliently slidable in the direction of the longitudinal axis of the roll, allowing the roll to be clamped between the two roll holders with pre-compression. Owing to this manner of bearing-mounting the roll in the housing, a stable positioning of the material web roll is obtained.
  • the housing preferably comprises winding means which are engageable from the outside of the housing and whereby the roll can be wound and unwound.
  • winding means can for instance be constructed as a crank or a turning knob.
  • the housing of the presentation assembly according to the invention can comprise fasteners for attachment to a board or plate-shaped part.
  • the attachment 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 of the plate-shaped part, so that the material web in a first position can be written on on one surface thereof, and in a second position can be written on on the other surface thereof.
  • an exemplary embodiment of the presentation assembly according to the invention which is particularly simple to transport is characterized by a stretching screen, which in a first condition is rolled up and forms a compact unit together with the housing, and which in a second 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 first 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.
  • the presentation assembly comprises a collapsible supporting frame which in a collapsed condition forms a compact unit with the housing.
  • 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 of a desired length is sawn from an extrusion section and provided with two end stops which also serve as roll bearing. In this manner, a number of presentation assemblies of different lengths can be manufactured in an economical manner.
  • 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 of being written on can be stuck flat to a base.
  • the presentation assembly shown in Fig. 1 consists of a plate-shaped part 1, built up of a number of laminations 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.
  • a supporting frame is indicated consisting of two legs connected by pivotable connecting arms 4.
  • the legs consist of leg parts 5 and 6, and the leg part 5 can be received within the leg part 6.
  • a detachable handgrip 15 is present, which also serves to fasten container 12 to a board 21.
  • an attachment receiving member is indicated. In this manner, a complete, optionally mobile presentation assembly is provided.
  • the presentation sheet assembly 2 is shown.
  • This assembly consists of a housing, indicated by 12, wherein a roll 10 of plastic film material 11 is accommodated whose film is electrostatically charged.
  • the housing can be opened in a simple manner, 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 superfluous 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 flat 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.
  • a cutting blade 14 which is operative adjacent the dispensing slot 13.
  • the cutting blade 14 can be moved forward and backward for the purpose of cutting off part 11 from the plastic film web.
  • 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.
  • the blade 14 operates on a hardened cutting strip 25 against which the blade 14 is pressed during cutting.
  • a groove is provided wherein the blade 14 operates. With such a construction, the risk of the film or paper 11 tucking up during cutting is minimized.
  • this film When an electrostatically charged plastic film is used for the material web, this film preferably has a thickness ranging between 30 and 60 ⁇ m, and more in particular a thickness of about 35 ⁇ m, and is preferably a white film. It has appeared that with the construction here shown, the electrostatic charge of the film material is maintained. This electrostatic charge is important for enabling a sheet of film 11, after the sheet 11 in question has been written on, to be fixed on a wall or the like without necessitating separate adhesive means. Obviously, the electrostatic charge is also important for keeping the film web, rolled up during a longer time, in a flat position when it is being written on.
  • Fig. 4 illustrates a further embodiment of the invention.
  • the presentation assembly is mounted on a leg consisting of telescoping leg parts 8,9.
  • a leg can for intance be secured to a wall by means of, for instance, suction cups or the like, and sheet material can be unrolled therefrom laterally in accordance with the invention.
  • Figs. 5 and 6 show an alternative embodiment of the presentation assembly according to the invention, wherein the collapsible plate part 1 has been replaced by a stretching screen 26.
  • the stretching screen 26 In a first condition, the stretching screen 26 is rolled up and forms a compact unit together with the housing, and in a second condition it is unrolled and stretched taut, so that it can serve as a base for an unwound part of plastic film web or paper web to be written on.
  • the screen 26 is tightened by a spring not shown, and can be unrolled to different extents by means of the toggle link assembly 27 shown in Fig. 6.
  • a presentation assembly of such design is of a light construction and easy to transport.
  • the plastic film web can for instance be a film of polypropylene, polyester or vinyl. It is understood that these materials are mentioned as an example only and that other film materials or mixtures of different types of film material can also be suitable. As indicated hereinabove, a paper web may also serve as material to be written on.
  • the material web has at least one relatively rough surface, so that the writing thereon is not erasable, and for the sake of the compactness of the presentation assembly, the material is disposed as a roll and comprises means whereby the material, inclined to roll up, can be stuck flat to a base, while the material web reminds the user of paper as much as possible.
