Definitions

  • the present invention relates to a disc captively mounted between two outer elements for rotation therebetween.
  • Discs mounted for rotation between two outer elements are well known.
  • one or more windows can be provided in at least one of the outer elements so that printed matter appropriately positioned on the disc can be selectively read. Rotation of the disc will then permit additional data to be read.
  • EP-A-0593820 one or both of the two outer elements are embossed so as to form a spindle about which a disc provided with a hole in the center thereof can rotate.
  • the two elements are glued together at the embossment with the disc sandwiched between the two elements.
  • a rotatable disc from a single flat cardboard blank.
  • the blank has three sections adapted for folding about two parallel fold lines.
  • a first end section forms the disc section and has at its central portion a frangibly releasable circular portion for providing the spindle of the finished item.
  • the remaining two sections form the outer elements and are folded about the disc section so as to sandwich the disc section therebetween.
  • the three sections are glued together by the application of glue to one side of the blank at the middle of the two outer elements and in a ring on the middle section of the blank.
  • the fold portions must be cut away from the folded item and a circular cut must be provided in the middle section, the cut being larger than and concentric with the cut-out spindle, and yet smaller than the ring of glue.
  • a first aspect of the present invention is a disc captively mounted between two elements for rotation therebetween, wherein the disc is attached at a peripheral portion thereof to one of the elements by a frangible connection, the breaking of which allows the disc to rotate.
  • the disc is fully circular so that the disc may be rotated through a full 360°C and the disc and two elements are formed from a single cardboard blank.
  • the two elements may be rectangular and linked together about the corners of the rectangles.
  • One or both of the elements may form an outer surface of a larger item.
  • One or both of the two elements may be provided with windows for selectively reading information printed on the disc.
  • the windows may be wholly or partially cut-out from the elements. Partially cut-out windows may be frangibly releasable and removed from the elements by the end user.
  • Part of the periphery of the disc may extend outwardly from the extremity of one or both of the elements, for example for allowing a user to grip the disc for rotation thereof.
  • the two elements form an envelope for the disc.
  • the two elements may be joined together by gluing, embossing, stapling, stamping or taping them together.
  • the elements could be formed from a single folded sheet of cardboard or plastic.
  • An intermediate spacing piece may be fitted between the two elements to facilitate smooth rotation of the disc between the elements.
  • windows can be formed on any part of the outer elements, including over the central area of the disc. Therefore a window of any desired shape can be provided. The window can overly the central portion of the disc. A plurality of second windows can also be provided.
  • Such windows can be elliptical and can be a single elliptical window together with a plurality of additional windows arranged around the periphery of the disk, the elliptical window being suitable for illustrating accurately the stars in the sky at night, for example;
  • the visible stars on a selected date and time can be depicted at the elliptical window by rotation of the disc relative to the outer elements, so as to select the correct date and time in the appropriate one of the plurality of second windows.
  • a method for the production of a disc in accordance with the first aspect of the present invention comprising providing a blank having first, second and third portions foldably connected together, the first and second portions forming outer walls and the third portion forming a disc and a spacer portion frangibly connected to the disc, folding said third portion to overlie said second portion, folding said first portion to overlie said third portion, and attaching said first portion to said spacer portion.
  • a blank for manufacturing a disc in accordance with the first aspect of the present invention is provided.
  • Figure 1 shows a disc 10 captively held within an envelope formed from two outer elements 12,14.
  • a first element 12 has cut-out windows 16 provided therein.
  • the disc 10 can be rotated in the direction shown by the arrows 18. Since the disc 10 is wholly circular, the disc 10 may rotate through a full 360° within the envelope.
  • a preferred method of manufacturing a device of the present invention, and in particular for commercial production of such discs, is to use a blank formed from a single sheet of card.
  • Figures 2 to 6 illustrate such a blank and the various stages during the method of manufacture.
  • the blank comprises a sheet having two fold lines 34,36 provided thereon defining three portions 40,42,44.
  • a first portion 40 defines a back element 14
  • a second portion 42 defines a front element 12
  • a third portion 44 comprises the disc 10 and spacer portions 24.
  • the third portion 44 is foldably connected to the second portion 42 along fold line 34 and the second portion 42 is foldably connected to the first portion 40 along fold line 36.
  • the third portion 44 comprises two spacing portions 24, the disc 10 being frangibly connected to the spacing portions 24 and the spacing portions 24 being foldably connected by fold line 34 to the second portion 42.
  • the front element 12, formed from second portion 42, has various cut-outs provided therein. There are three forms of cut-outs in this second portion 42.
  • the first type of cut-out is an array of windows 16.
  • the second type of cut-out is an oval shaped window 26 and is particularly suitable for a rotating disc for displaying, for example, the sky at night.
  • the cut-outs may be die-cut from the blank before assembly of the disc, as has been done with the array of windows 16. However the windows may be merely partially cut out for frangible release by the end user, such as has been done with the oval shaped window 26.
  • a finger hole 38 is provided in order to facilitate the removal of the oval shaped window 26, . This can be pressed from the blank prior to assembly.
  • the third type of cut-out is a pair of ports 28 through which the rim of the disc 10 extends in the assembled product.
  • the two ports 28 form arcuate cut outs 30 such as those provided at the edge of the envelope for facilitating gripping of the rotating disc 10 for rotation thereof within the envelope.
  • the ports 28 are optional since in alternative embodiments the rim of the disc 10 may extend beyond at least one edge of the outer elements.
  • the ports 28 are positioned centrally across the fold lines 34, 36.
  • the first portion 40 of the blank 22 has a similar size and shape to the second portion 42, both being substantially square and the fold lines 34,36 are arranged parallel to one another. Windows may be provided for viewing data printed on the reverse side of the disc 10.
  • the steps required to manufacture a disc using the blank 22 involve folding the third portion 44 up and over the second portion 42 so as to overlie the second portion 42 and then folding the first portion 40 up and over the combined second and third portions 42 so as to overlie the third portion 44 thereby captivating the rotating disc 12 between the second portion 42 and the first portion 40.
  • Two connecting points 32 identified on the first portion 40 are arranged to meet the spacing portions 24 upon folding the first portion 40 over the second and third portions 42,44.
  • the surfaces of either or both of the connecting points 32 and the spacing portions 24 are provided with an adhesive so that the spacing portions 24 and the connecting points 32 can be pressed together to link them and the elements together to form a first two of four connections between the elements.
  • the hinges formed by the fold line 36 between the first and second portions 40,42 provide third and fourth connections between the two elements 12, 14, separated by the port 28 positioned across the fold line 36. A minimum of three connections between the two elements 12, 14 could be provided, dependent upon their relative positions around the disc 10.
  • the frangible connection In order to enable the disc to rotate within the envelope thus formed, it is necessary to fracture the frangible connection between the spacing portions 24 and the rotating disc 10, which should be a simple matter of applying a rotation force to the portions of the rims of the disc 10 which extend through the ports 28.
  • the frangible connection could be broken by the folding machine.
  • the frangible connection may be in the form of nicks which may be released to some extent during these folding and gluing steps.
  • the blank 22 can be formed and folded one at a time for producing a low volume of rotating discs, it should be appreciated that in an automated process producing large volumes of these discs, a die cutting machine may operate to process, one after another, entire print sheets, so as to generate arrays of blanks simultaneously. These arrays of blanks may then be fed in continuous manner as a stream of individual blanks to a folding and gluing machine.
  • outer elements need not be square, or even rectangular.
  • one or both could be triangular with up to three portions of the rim of the rotatable disc extending beyond the extremities of the triangular outer element.
