Definitions

  • the present invention relates to a strip display comprising a strip carrying a series of visual information and stretched between two rolls on which it is wound and driven synchronously, and a display device comprising several strip displays, in particular for the automatic display of oil prices.
  • Displays are known carrying only a single visual information carried by a removable fixed plate in a housing in which are arranged lighting means. With such a display, the change of information must be carried out manually.
  • strip displays comprising a strip wound on two rollers driven by a double clutch device cooperating either with one or with the other of the rollers.
  • Such a display requires the presence of moving parts and therefore a large footprint and cost.
  • the tension of the strip is not ensured regardless of the position of the strip.
  • the strip carries indications each corresponding to visual information carried by the strip are intended for controlling the position of the strip.
  • the strip carries as many marks as there are indications and intended, by comparison of the indication corresponding to the image to be displayed with the indication corresponding to the displayed image and by counting marks, for positioning the strip.
  • the invention also relates to a display device characterized in that it comprises a series of strip displays according to the invention, arranged in a common housing.
  • Figure 1 shows a strip display comprising a frame consisting of a first and second side plates 2 connected together by two rear plates 3a for fixing the display on a support or in a housing (not shown) and a front plate 3b (partially shown).
  • the first roller 5 is arranged in the vicinity of the upper end of the chassis, the shaft 4 projecting outwards from the second side plate.
  • the second roller 9 is arranged in the vicinity of the lower end of the chassis, the two shafts 4, 8 being parallel.
  • the strip is stretched in the vicinity of the front edges of the side plates 2 by means of two positioning rollers 13 loosely mounted on shafts 14 fixed on the chassis above the first roller and at the below the second roll respectively.
  • lighting means are arranged inside the chassis 1 behind the strip 12, the strip sections carrying the information being transparent, translucent or fluorescent for the purpose of night-time operation.
  • the strip carries marks 15, the counting of which by one of the detection means 16, intended to be connected to a data processing circuit (not shown) and carried by an angled rim of the plate 3b, during the movement of the strip, allows the positioning of the strip for particular visual information to be displayed.
  • the strip also carries indications 17 intended for monitoring the state of the strip and for its positioning and detected by the other detection means 16.
  • these detection means 16 can be constituted by infrared cells arranged above the first roll, the marks and indications being located on the strip above each visual information.
  • a drive mechanism 18 for the rollers comprises an electric motor 19 fixed inside the chassis on the second side plate 2.
  • the axis of rotation of the motor is parallel to the shafts of the rollers 5 and 9 and projects outwards from this side plate.
  • a drive toothed wheel 20 is wedged on the part of the projecting shaft and cooperates with a toothed belt 21.
  • This toothed belt also cooperates with a first toothed pulley 22 wedged on the shaft 4 of the first roller, a second pulley toothed 23 mounted madly on the shaft 8 of the second roller and two idler rollers 24 rotatably mounted on this side plate and located on either side of the first toothed pulley so as to maintain sufficient grip of the belt on this pulley.
  • the second pulley 23 is connected to the shaft 8 by means of a spiral spring 25 housed in a housing 26 formed in the pulley.
  • the spiral spring 25 is fixed by one of its ends to the peripheral wall 27 of the housing 26 and by its other end in a notch 28 of the shaft 8.
  • This spiral spring 25 is intended to compensate for the tension of the strip 12 as a function of the variation in the diameters of the rollers driven synchronously, resulting from the winding of the strip.
  • FIG. 4 represents a curve of variation of the length of strip to be compensated (or of the resistance opposed by the spiral spring which is there proportional) as a function of the position of the strip or of the difference in the winding diameters of the two rollers, these rollers having the same diameter when empty.
  • the curve describes a parabola and goes through a minimum when displaying the middle of the strip, the two rollers then having the same winding diameter.
  • the length of strip to be compensated increases on either side of this midpoint due to the variation of the difference between the diameters of the rollers as shown in Figure 4 below the position of the strip shown as d 'example by numbers from zero to nine symbolizing visual information regularly spaced on the tape.
  • the spiral spring has a minimum reserve tension at the midpoint.
  • the number of revolutions of the roller 5 progressively goes from 2, 8 (information 0) to 3.2 (information 9); at the same time, that of the roll 9 passes from 3, 2 to 2, 8, the compensation between the two rollers being ensured by the action of the spiral spring which also maintains a substantially constant tension of the strip 12.
  • FIG. 5 represents a block diagram of a device for controlling a strip display according to the invention which can be adjusted from coding wheels 30 intended to be placed at a distance from the display.
  • the encoder wheels 30 are connected to a reading and validation circuit 31 itself connected to a conventional data processing circuit 32, for example a programmable controller.
  • the detection means 16 for example infrared cells, which detect, during their passage, the marks 15 or studs and the indications 17 of the position of the strip, are also connected to the circuit 32 of the data processing.
  • the marks and indications are located above each item of information so that they are located opposite the detection means when the corresponding image is displayed.
  • An output of the circuit 32 is connected to the electric motor 19 via an adaptation interface (not shown).
  • the reading and validation circuit When the reading and validation circuit is commanded, it sends to the data processing circuit the value X of the coding wheels corresponding to the information to be displayed.
  • the circuit 32 then receives detection means, the value Y corresponding to the information displayed and given by the indications 17, for example in BCD code.
  • the circuit 32 performs the comparison of the two values and controls the motor to advance the strip of X-Y information, by counting the marks by means of the detection means, or to make it move back according to the sign of X-Y.
  • the circuit 32 can then carry out a second verification comparison.
  • displays of reduced cost and low bulk it is possible to produce a display panel comprising a series of displays and control the display remotely.
  • a particular application of these displays is the display of petroleum prices, the order of which can be carried out in parallel with that of the display of the price at the pump.
