Definitions

  • the present invention relates to a number indicator.
  • the present invention relates to a number indicator, with manually controlled magnetic movement, for price lists.
  • the prices must be displayed not only on the distribution pumps, but also at the entrance of the filling station as an indication to drivers passing the station.
  • the indicator displaying the prices of fuel at the filling station must be well in sight and of easy access to the salesman who must punctually up-date the selling-prices.
  • the indicators which form the sales prices of the fuel must consequently satisfy various requisites. As they are exposed to the open-air, they must have a good, long-lasting resistance to the action of atmospheric and polluting agents, they must be of such dimensions as to be visible from a distance, they must have a limited cost and, as already mentioned, they must be easily adjustable owing to the variations in the prices of fuels.
  • the Applicant has now invented a number indicator which can be used in the preparation of price-lists which can satisfy some or all of the above requisites. It can, in fact, be made by using a traditional polymeric material and can be easily controlled, from zero to nine, as it is equipped with a manually controlled magnetic operation.
  • a number indicator comprising:
  • the magnetic means comprise a metal chip made of ferromagnetic material attached to the associated plate.
  • the seven cavities may be elliptical and the over centre means may comprise a stop-spring centrally welded to each metal chip and, at the ends, to the apices of each elliptical cavity.
  • the flat sheet which may be serigraphed with black ink and the flat support may be joined to each other to form an article with an essentially rectangular surface of such dimensions as to be visible at a distance.
  • the shorter side of this rectangular structure may be between 10 and 18 cm whereas the longer side may vary from 18 to 30 cm.
  • the transparent sheet can be made of glass or transparent polymeric material, for example polymethylmethacrylate. Suitably, it has a thickness of a few millimetres, for example 1-3 mm, and may be serigraphed with the known techniques.
  • the flat support is made of polymeric material and is dyed with light colours, for example white or yellow, so that the figures can be clearly read through the non-serigraphed parts of the sheet.
  • the support made of polymeric material such as polyethylene, polypropylene, polymethylmethacrylate, etc. has a thickness of 5-15 mm.
  • the cavities in the sheet can be obtained by milling a pre-extruded sheet or shaping, by injection moulding, a sheet already equipped with said cavities.
  • the stop-springs are lodged in the cavities of the supporting sheet, which, when not in use, have a length which is greater than the length of the major axis of the elliptical cavity and less than its semiperimeter.
  • a ferromagnetic metal chip is welded to each spring, which can be moved manually with a permanent magnet. As the stop-spring is lodged in the cavity and is fixed at the ends of this, the movement of the metal chip can occur only with orthogonal motions towards the longer axis of the elliptic cavity.
  • a black thin plate is firmly attached to each metal chip, shaped so as to reproduce the form of the corresponding digital character (or numeral part) on the serigraphed sheet.
  • Each thin plate is attached to the metal chip in such a way that it is in line with each character of the digital number.
  • the metal chip moves, by effect of the magnet, it also pulls the black thin plate which, when the movement has stopped, can cover or reveal the character of the digital number, thus forming any figure from zero to nine. It is evident that for the thin plate to be perfectly superimposed on the digital character there must be precise correspondence between the digital number displayed on the transparent sheet and the elliptic cavities on the flat support.
  • Night visibility of the figure displayed on the indicator of the present invention can be ensured by a light source positioned behind the flat support.
  • a light source positioned behind the flat support.
  • (A) represents the transparent sheet serigraphed with black ink to allow the transparent reading of the number eight according to the digital figures (A1)-(A7).
  • (B) represents the flat support with the cavities (B1)-(B7) reproduced on the surface. Stop-springs (C) are lodged in the cavities, fixed to the ends (C1)-(C7) at the apices (b) of the cavities themselves.
  • the ferromagnetic metal chips (D) are welded to the springs, onto which the black thin plates (E1) and (E2) so shaped as to reproduce the corresponding digital characters (or numeral part) (A1)-(A7), are in turn fixed.
  • the functioning of the back-lighted ciper-indicator for price-lists of the present invention is evident from the drawings of the enclosed figures and the above description.
  • the serigraphed transparent sheet (A) is joined to the flat support containing the stop-springs, the ferromagnetic chips and the black thin plates assembled as shown in Figures 3 and 4.
  • the sheet can be glued to the flat support or fixed with shelf-threading screws.
