Description

1 - The subject of the invention is improvements to or

  relating to sheet material suspension devices.

  The present invention relates to devices for

  pension of material in sheets, for example printed paper in the form of a poster.

  According to the invention, there is provided a device for

  board of material in sheets, comprising several sheets

  interconnected to form a laminated structure

  te, and a first and a second band attracting magnetic-

  mutually attached to the inner surfaces of the first and second, respectively, of the various sheets, the first sheet having an elongated middle region capable of articulating to allow the portion of the first sheet to which the first band is attached, to be removed from the

  part of the second sheet bearing the second strip for in-

  troduce the sheet material between the first and the second band. Thus, it is possible to provide a device for suspending a sheet of material which is easy to manufacture and low production cost. The flat laminated structure can be easily formed by adhesively bonding the sheets together and bands which attract magnetically. The arrangement of the medial hinge region simplifies the use of the device since it is simply necessary to articulate the first band and the portion of the first sheet to which it is attached to separate it from the board.

  second band, for example, by a take-off movement of

  then a free edge of the first band When the device

  is attached to a support surface, in particular with the sur-

  outer face of the second sheet adhered to the

  surface, the arrangement of the joint and the movement of

  their effect on the fixing of the

  positive to the support surface Thus, one can achieve a solid fixation that withstands the repeated use of the suspension device of sheet material, with relatively few

  risk that the device will become detached from the support surface.

  Preferably, the first sheet is formed of a

  Such a material is particularly suitable for

  to ensure the hinge area and allows a considerable number of joints before there is wear

or deterioration.

  Preferably, a third sheet, for example of polystyrene-high impact resistance, is disposed between and

  related to the inner surface parts of the first and second

  x sheets not attached to the first and second strips This

  ensures a stratified structure that is particularly

  ple and to have good stability in use.

  Preferably, the outer surface of the second strip is covered by and attached to a polyester membrane whose outer surface is covered with an adhesive layer to secure the device to a support surface. The adhesive layer

  is preferably protected by a removable sheet, for example

  silicone paper makes it easy to assemble

  the device on a support surface, by means of a

  simple structure that is not expensive to manufacture.

  The polyester membrane and the adhesive layer are preferably transparent, to allow the printing or other decoration to be seen on the outer surface of the second sheet, for example, when the device is mounted on a

glass pane.

  Preferably, the first and second strips are

  magnetic tapes These tapes are relatively thin

  and flexible and can be easily attached to the structure

  layer to allow the sheet material to be held together by magnetic attraction. However, it would also be possible for one of the strips to be magnetic

  permanence and that the other is ferro-magnetic.

  Thus, it is possible to provide a device that is

  simple and inexpensive and which has a long life.

  store displays or the like, and promotional material in the form of posters or the like, can be updated at regular intervals. Both the first and second sheets can be made

  vinyl laminate which allows the simple device to be cleaned

  In this way, the device can be used in environments where hygiene is important, for example in

hospitals.

  The device has the shape of a rectangle, the area of

  device can have any desired shape.

  The invention will be further described, by way of example, with reference to the drawings.

  first and second printed vinyl laminate sheets (2 and 3) and a high strength polystyrene sheet (4)

  The adhesive layers (5 and 6) on the surfaces

  of the leaves (2 and 3) bind together the sheets (2 to 4) and also fix the antagonistic magnetic tapes

  (7 and 8) to leaves (2 and 3), respectively.

  3 - The adhesive layer (11) and the polyester membrane (9) are both transparent and allow to see what is printed on the outer surface of the sheet (3) to

through the glass.

  In general, the suspension system is arranged with the hinge zone (13) horizontal, as shown in Figures 2 and 3 of the drawings In order to fix a poster (14), the magnetic tape (7) and the part of the sheet (2) to which it is attached, are hinged upwards to the position shown in Figure 2 The upper edge of the poster (14) is then introduced between the strips (7 and 8) and the strip (7) is disengaged so that the magnetic attraction between the strips (7 and 8) causes the return of the strip (7) to the position shown in Figure 3 The edge of the poster (10) is thus taken between the strips (7 and 8), as a result of the attraction

  which is strong enough to allow

  dre a poster (14) without the need for other support.

  Subsequently, if desired, the poster can be removed by lifting the strip (7) to disengage the upper edge

of the poster.

  The poster can be arranged so that what is printed is visible through the glass pane, as well as or instead of the side of the glass on which the suspension system

  the poster suspension system is not limited to such uses and can be attached to any suitable surface which may be vertical, horizontal or sloping. The suspension system may, for example, be used to suspend

  letters, notes, notebooks and others.

  Although the variant described with reference to the drawings comprises an extensible suspension system large enough to suspend a poster, the suspension system can be made to any suitable shape or size. In addition, the suspension system can be colored as well as place to wear

  impressions, so as to have an aesthetic appeal.
