Definitions

  • This invention relates to signs of the kind which incorporate a plurality of display items, for example in the form of information, instruction, pictures or other matter, and in which a selected item can be brought to a display position to permit it to be viewed; the invention relates more particularly to such signs in which the display items are carried by a web of a suitable flexible material, the ends of which are carried by respective supporting rollers, these signs being commonly known in the art as roller blind signs and will hereinafter be referred to as such.
  • An object of the invention is to provide a form of roller blind sign incorporating a simple drive system for the supporting rollers, but which provides an effective solution to this latter problem.
  • a roller blind sign incorporates means mechanically coupling the supporting rollers to each other for enabling them to be rotated in unison by a common reversible drive means for bringing a selected one of the display items in the display position, and a movable jockey roller over which the part of the web between the supporting rollers passes, which jockey roller is biased in a direction which maintains the web under tension as it is transferred from one supporting roller to the other.
  • an appropriately biased jockey roller ensures that the web is held under a suitable degree of tension throughout the whole of its transference from one supporting roller to the other, thereby compensating for changes in the length of the part of the web between the rollers due to the differences in the effective diameters of these rollers as the web is transferred.
  • Biasing of the jockey roller is preferably effected by spring means, although for some applications of the invention, depending upon the orientation of the sign, it may be provided by gravity.
  • the supporting rollers are preferably of substantially the same diameter, and the coupling between them is such as to cause these rollers to be rotated at identical angular velocities.
  • the drive means may, for example, be connected or connectable to drive one roller, with that roller coupled to the other by means of interengaging pinions.
  • the coupling may be provided by pinions fixed to shafts drivingly supporting the rollers, and either engaging each other directly or through one or more intermediate pinions.
  • the rollers may be coupled by a chain and sprockets, or by a timing belt and associated pulleys.
  • the drive means may be applied to an intermediate rotatable member similarly coupled to both supporting rollers.
  • the drive means may comprise a manually operable handle or hand-wheel, fitted or capable of being fitted to an extension of the shaft of at least one of the rollers, or to the shaft of a said intermediate rotatable member where provided.
  • the drive means comprises a reversible electric motor coupled to the shaft of at least one of the supporting rollers, or to the intermediate rotatable member where provided, through a reduction gear system.
  • a reversible electric motor coupled to the shaft of at least one of the supporting rollers, or to the intermediate rotatable member where provided, through a reduction gear system.
  • Means may then be provided generating position indicator signals indicative of the position of the web, and display means at the remote control position for indicating which of the display items is in the display position.
  • each display item may have associated with it on the web, or means movable therewith, a position indicator corresponding to that item, the sign incorporating a detector located adjacent the path of the position indicators on movement of the web and arranged to generate a position indicator signal appropriate to a respective display item when that item approaches or reaches the display position.
  • Means responsive to said position indicator signals may also be provided for automatically arresting the web with a selected display item in the display position.
  • the sign illustrated comprises a web 1 of any suitable flexible material such as a fabric or a plastic, the ends of which are firmly fixed to two similarly dimensioned supporting rollers 2, 3 respectively, the web having, disposed along its length, a plurality of different indicia required to be individually displayed at a display position represented by the broken line D ( Figure 1).
  • the rollers 2, 3 are mechanically coupled by intermeshing identical pinions 4, 5 attached to shafts 12, 13 drivingly supporting the rollers 2, 3.
  • the web 1 In order to display the signs, the web 1, after it leaves the supporting roller 2, passes over a first idler roller 6 mounted at a suitable distance above the roller 2, depending upon the height of the matter required to be displayed, the web then passing over a further idler roller 7 before reaching the other supporting roller 3.
  • the web instead of extending directly between the two idler rollers 6, 7, the web is passed under a jockey roller 8 which is free to move vertically and take up the slack existing between the jockey rollers 6, 7 either by the action of gravity or preferably by means of a pair of springs as shown at 9.
  • the drive means may comprise a handle or hand-wheel, fitted to the shaft extension as indicated, for example at H, to enable the display matter to be changed manually. In other circumstances; when for example the sign is disposed at some height from the ground, it is convenient to use an electric notor as the drive means.
  • the motor In such a case it is convenient to fit the motor with a reduction gear to ensure that the sign does not change too quickly as this might make it difficult to stop the web 1 accurately at a desired position. It is obvious that means must be provided for driving the supporting rollers 2, 3 in either direction and for this purpose the electric motor employed is preferably one which is easily reversed without complicated switching, such as for example what is generally referred to as a capacitor motor where it is only necessary to make connection to either of two windings to reverse the direction of rotation, but obviously any type of motor with appropriate switching may be employed.
  • springs are employed, as at 9, they should be of sufficient strength to provide the required tension for the web over its whole range of movement, for example by making them as long as practicable and using a low rating spring, as with a long web the change in length of its central part may be appreciable, and the use of too highly rated springs will necessitate the use of additional power to move the web.
  • the sign may be enclosed in an outer casing represented by the broken line S with the display position D provided by an opening in the casing, preferably covered with a transparent panel, for example of glass (not shown) through which the matter displayed can be viewed.
  • a transparent panel for example of glass (not shown) through which the matter displayed can be viewed.
  • the second sign which is illustrated in Figures 3 and 4, is somewhat similar to that described with reference to Figures 1 and 2, in that it comprises a flexible web 1 carrying individual items for display and having its ends fixed to respective supporting rollers 2, 3.
  • the idler rollers 6, 7 are spaced wider apart, and two further idler rollers 16, 17 are disposed slightly below them just forwardly of the rear roller 7 as shown in Figure 4.
  • the jockey roller 8 in this case is located at the rear of the sign, the web 1 passing beneath it between the two idler rollers ? and 17; the spring-biased jockey roller 8 is biased downwards as before by springs 9, and thereby compensates for changes in the effective length of the web 1 as it is transferred from one supporting roller to the other, and thus maintaining the web under tension throughout as in the previous embodiment.
  • the web 1 may be provided with what are generally referred to as locating means, each individual sign having its own locating means as, for example at 18 ( Figures 3 and 4).
  • locating means each individual sign having its own locating means as, for example at 18 ( Figures 3 and 4).
  • detectors of many different kinds for example proximity switches or similar electro-magnetic devices as well as opto-electronic devices.
  • the locating means on the web 1 may be of any convenient form necessary to actuate the particular type of detector employed. For example when an opto-electronic system is used each individual sign would have its own individual mark.
  • the signal generated by the detector (shown for example at 19) would be used to control the motor 14 driving the web 1 and cause it to stop when the selected signal matched an appropriate signal from control equipment, shown at 20, located at the remote point.
  • This arrangement is mentioned as a known method of location which may be applied to any sign not in any way forming part of the present invention but indicates how existing practice may be associated with it.
  • the sign may be front illuminated but alternatively rear illumination may be used in which case the belt may be made of transluscent material with a light source located behind it which conveniently comprise fluorescent lamps, as at L in Figure 4, the number employed being determined by the light rating of the lamps and the physical size of the sign.
  • a light source located behind it which conveniently comprise fluorescent lamps, as at L in Figure 4, the number employed being determined by the light rating of the lamps and the physical size of the sign.
  • the web 1 can, for example, carry ten individual display items respectively showing figures from 0 to 9 one such item in the form of the Figure 7 being shown at the display position D in Figure 3.
  • two or more signs made as identical physical units are conveniently assembled together as a composite unit within a common casing. It will be seen that by assembling three such units, for example, any price between one penny and nine pounds ninety nine pence could be displayed. However the matter displayed can take any other required form.
  • control equipment 20 When the sign is controlled by an electric motor from a remote position but with the sign visible at the control point it may be found convenient to provide the control equipment 20 with either two push buttons which cause the motor to be energised as long as they are in the closed position, one marked “Raise” and the other marked “Lower” or alternatively with a single press button for the motor together with a two position switch similarly marked.
  • the variation in the length of that part of the web between the supporting rollers may be greater than can be accommodated by movement of a single jockey roller within the confines of the casing of the sign, and in such a case one or more additional suitably-biased jockey rollers may be employed, the web being looped round each jockey roller in turn.
