Definitions

  • This invention relates to display apparatus.
  • the invention provides display apparatus comprising a frame around a rigid backing surface, the frame having a channel-shaped cross-section which is shaped to grip the outer margin of a semi-rigid sheet sufficiently to prevent the sheet from being distorted and hence removed from the frame.
  • a double bend is put in the outer margin of the sheet to provide the sufficient grip and preferably the channel-shaped cross-section of the frame is shaped to provide three bearing points with which to put the double bend in the outer margin of the sheet.
  • the semi-rigid sheet may itself contain the display or it may simply be a transparent sheet for sandwiching an ordinary paper display against the rigid backing surface.
  • the frame comprises a plurality of assemblable frame members and means is provided for releasably assembling together the frame members, which means is inaccessible after assembly of the frame, and there is preferably also provided means for gaining access to the means for releasably assembling together the frame members to enable disassembly of the frame.
  • Such means may be a special key and may require sacrificing the display sheet itself.
  • a tongue 14 on the fourth side 10d engages a latch 15 which is pivotally mounted by a pivot 16 to the third side 10c.
  • the latch 15 is biased towards its engaged position by a spring 17.
  • the engagement mechanism is housed within the confines of the frame members so that, once engaged, the frame cannot be released without the use of a special tool.
  • the special tool is, for example, a key which has to be inserted through the display (which is therefore sacrificed) to disengage the latch 15.
  • the frame member is of a basically channel-shaped cross-section, conveniently extruded aluminium, with an interior 20 defined between front and back wal ls, 21 and 22 respectively, and an end wall 23.
  • the frame member here is attached to a rigid panel 24.
  • the frame member may, however, be attached directly to some other rigid backing surface, eg a wall.
  • a semi-rigid sheet 25 is supported against the panel 24, with its margin gripped within the interior 20 of the frame member.
  • the sheet 25 is semi-rigid in the sense that the sheet is relatively easy to flex in one plane, but very much harder to flex in two different planes at one.
  • Examples of semi-rigid sheets are conventional laminated or encapsulated signs which are used eg in advertisements in Underground stations.
  • the margin of the sheet 25 is gripped by a three point bearing.
  • the front wall 21 of the frame section has a turned over lip 26.
  • the point of contact between this lip 26 and the sheet 25 forms the first bearing point 27.
  • the back wall 22 of the frame section has a ridge 28, and the point of contact between this ridge 28 and the sheet 25 forms the second bearing point 29.
  • the third bearing point 30 is the point where the outer edge of the sheet 25 contacts the interior face of the outer wall 21 of the frame section. It will be seen that the three point bearing from the frame section puts a double bend in the margin of the sheet.
  • Figure 4 there is seen a modified form of the frame section profile of Figure 3.
  • the interior surface of the end wall 23 ⁇ is radiused and the ridge 28 ⁇ on the interior of the back wall 22 ⁇ is somewhat smaller.
  • the first and second bearing points 27 ⁇ and 29 ⁇ are as in Figure 3, but the third bearing point 30 ⁇ is formed by the point of contact of the outer edge of the sheet 25 with the interior radiused surface of the end wall 23 ⁇ .
  • FIGs 6 to 9 various alternative examples of frame section profile.
  • the lip 40 is provided as a separate item which is attached, eg with dowel pins, to the main frame section.
  • an additional channel opening 41 is also seen in the frame section profile of Figure 6 .
  • This provides useful space behind the display. The space can be used to house back-lighting for the display, for example. More sophisticated devices such as a removal alarm or selective lighting with touch control can also be incorporated in this space.
  • the frame section seen in Figure 7 is extrusion-rolled and those of Figures 8 and 9 are rolled sections.
