Definitions

  • the present invention relates to display signs, in particular to illuminated display signs.
  • a disadvantage of such a construction is the need for the provision of a substantial frame to mount the display plate.
  • the frame When such displays are fixed to a pole, as is frequently the practice, for example, in the motor trade, the frame must be particularly rigid and capable of withstanding severl weather conditions.
  • the present invention is predicated upon the realisation that the profiled sheet material disclosed in GB-A-1,530,371 is visually appealing and can be employed as the display plate instead of merely acting as a means for supporting such a display plate.
  • an illuminated sign comprises a display plate in the form of a profiled sheet which is curved to form a rigid structural element and has at least one cut-out, transparent or translucent portion shaped in accordance with the desired legend or logo to be displayed.
  • the display plate is rigid in itself, it no longer requires a rigid frame to support it, thereby enabling a display box to be made of light construction while providing a dramatic visual effect.
  • the profiled sheet material is anodised aluminium, having a highly reflective anod- isation coating.
  • the sheet is made of aluminium or metal, it is preferred to form the sign by cutting away the material in accordance with the desired legend or logo to be displayed.
  • a particularly attractive display is obtained when the lettering or logo is coloured only on the parts parallel to the general plane of the profiled sheet while the upstanding portions of the lettering are left uncoloured and translucent.
  • a halo effect is obtained around each individual letter.
  • the sheet may be alternatively made of a plastics material.
  • the profiling and the legend or logo may be formed by vacuum moulding a sheet of acryJic material. It is desirable to paint the acrylic material so that the background should be opaque when internally lit while the legend remains translucent. Such a construction may be similar to that of the aluminium construction previously described.
  • the framework may be relatively simply constructed for the purpose of supporting the internal light sources and may be formed with double channelled extrusions at its upper and lower edges into which the profiled sheets may be slotted and secured.
  • a box sign is shown mounted on a pole 10 by means of nuts and bolts 12.
  • the box sign includes a frame comprising uprights 14 and two horizontal sides 16 in the form of H cross-section extrusions.
  • the frame in itself does not have any substantial structural rigidity and serves merely to support two fluorescent tubes 18 and to mount the front and rear display plates 20 which assure the structural rigidity of the assembled box sign.
  • Each of the front and rear display plates 20 is formed of a profiled sheet of anodised aluminium, the profiling being such that the material is formed with parallel corrugations 22 which may be of triangular or preferably trapezium shaped section. After profiling, the sheet is rolled at its bottom edge 24 and its upper edge 26. The combination of profiling and curving by rolling is to enable the sheet to withstand distortion in any plane.
  • the front and back display plates are assembled onto the frame by slotting the upper and lower edges of the sheets into the channels defined by the H cross-section extrusions and securing the panels to the extrusions by any convenient fasteners such as rivets or screws.
  • two end plates 30 are provided one at each end of the frame and these are secured, for example by means of self- tapping screws, onto the uprights 14 of the frame.
  • cut outs are formed in the aluminium sheet 20 such as the oval cut out 32 shown in the drawing. Light from the fluorescent tubes 18 escapes through the cut outs to display the logo or legend by night.
  • an acrylic moulding may be inserted through the cut-out portion.
  • the acrylic moulding has sides protruding through the cut-out and a front face of the same shape as the cut out painted in a colour, such as blue or red, contrasting with the anodised aluminium.
  • a colour such as blue or red
  • the lettering or the logo may stand out sharply against the background of the aluminium sheet.
  • the illumination of the logo or the lettering of the legend by the internal lights results in light escaping from the sides of the moulding to form a halo effect enhanced by the anodised aluminium and surrounding the backlit lettering in the contrasting colour. It is believed that this provides a particularly striking and attractive appearance.
  • the plastics moulding may be conveniently be used as a means for supporting the cut-out centre of the letter.
  • the moulding would not be annular but the centre of the 0 would remain and the cut-out circle from the aluminium sheet would be adhered to the central portion of the letter to give the appearance of a continuous sheet with an annulus cut-out.
