Definitions

  • the present invention concerns a device for the formation and replacement of messages in advertising or informative display panels with multiple message by means of rotary prisms.
  • the aforementioned panels are well known and used. They consist of a plurality of prisms positioned side by side and each rotating about its own longitudinal axis. At each rotation, controlled for the desired angular length and at preset time intervals, a different face of each prism is shown in a way that the whole of the displayed faces show each time a message which can have informative or advertising purposes. Therefore each face of each prism practically carries a fraction of message which, combined with the others, forms the complete message.
  • the first solution involves very heavy maintenance charges, because of the need of mechanically removing the image formed by the panel.
  • the second solution providing the prearrangement of the message on aluminium or plastic strips corresponding to the prism faces, also results in quite high costs for the message replacement; because it is very difficult and time-consuming to detach the strips from the means that mechanically fasten them to the prisms, and then apply the new strips, maintaining the panel in place in a position where usually access is limited.
  • the means for mechanical fastening or coupling are cumbersome and can interfere with the section of message shown.
  • the object of the present invention is a device of the aforementioned type, which allows a quick and easy replacement of the messages on panels in place, eliminating all inconveniences of the known systems and reducing the costs not only for maintenance but for production as well.
  • a device for the formation and replacement of messages in advertising or informative display panels with multiple message, of the type wherein several prisms positioned side by side and controllably rotating about their own axis carry, on each face, a portion of a message formed in its entirety by all the message portions placed on the faces of the prisms having the same orientation, characterized in that each face carrying a portion of message in each prism is provided with one or more holding magnets, and by the fact that said portion of message is prearranged on a foil made of ferromagnetic material to be removably fastened onto the prism face thanks to said holding magnets.
  • prisms for multiple-message panels characterized in that they comprise a device of the above described type, as well as multiple-message displaying panels comprising the aforementioned prisms.
  • a prism 10 which may be triangular, square or provided with more sides, is controllably rotated, in a known way, about its own longitudinal axis 11, each time for an angular length depending on the number of its faces and at preset angular intervals, together with other equal prisms forming the panel.
  • magnetic elements preferably as two magnetic strips 13 and 14 applied, e.g. sticked, onto the longitudinal edges of the prism face.
  • FIG. 3 shows a further embodiment of the device according to the invention.
  • the holding magnets consist of elements 21, 24 to be housed within suitable seats provided along the longitudinal edges of the prism 22.
  • the elements 21 are at least two and are positioned transversally on to the relevant face of the prism.
  • the elements 21 are fixed by housing their ends into the corresponding seats 23 provided on said longitudinal edges of the prism 22. Preferably the elements 21 are spaced along the whole corresponding face of the prism.
  • Figure 3 also shows a second variant, similar to the above described one, according to which the holding magnets 24 are positioned longitudinally along the edges of the prism 22 and are housed into relevant seats 25 provided on said longitudinal edges.
  • the prism is consisting of an extended element having a plurality of projections provided in correspondence with the longitudinal edges of the prism so as to form seats 23 or 25 to house magnets 21 or 24, respectively.
  • the above described strips 13, 14 or the magnetic elements 21, 24 securely but removably hold a foil 15 made of ferromagnetic material, for instance sheet steel, that preferably covers the whole face of the prism and carries, at least on its outward surface 16, a portion of a message, whose other portions are reported on equal foils applied to the other prisms of the panel.
  • a foil 15 made of ferromagnetic material, for instance sheet steel, that preferably covers the whole face of the prism and carries, at least on its outward surface 16, a portion of a message, whose other portions are reported on equal foils applied to the other prisms of the panel.
  • the foils 15 can be provided with one or more pivots 17 (fig. 2) which are housable into holes 18 of the prism face.
  • the pivots 17 will have to be such as not to project on the visible side, for instance they will be mounted axially movable with respect to the foil 15, so that their head 19 each time is substantially coplanar to the visible face.
  • the replacement of the message is performed by simply removing manually the foils from their position on the faces of the prisms and by upturning said foils or replacing them with other foils carrying other portions of message, which are held in position without any element on sight and with strength sufficient for the use for which they are designed.
  • the used foils can be used again, or better, because of their low cost, be thrown away.
