Definitions

  • the present invention relates to compressor bars for use securing documents within document files of the type that include a pair of prongs that engage holes in the margin of documents to keep the documents within the file.
  • prongs may be incorporated into rings or arches for easier reading of the document within the file (so-closed ring binders or arch lever files).
  • compressor bars are placed above the documents in the file, pressed down on the documents and fastened to the prongs.
  • a general type of compressor bar is known that comprises:
  • the flexing means is part of an arm that is secured to the base by two side-by-side lugs that are inserted into a slot in the base such that the lugs are positioned adjacent to the edge of the slot.
  • the lugs each have a finger that is bent to overlap the edge of the base next to the slot and thereby prevent the arm from being pulled out from the base.
  • Such an arrangement also provides a pivot about which the arm can move so that the flexing means can in turn move between the first and second positions mentioned above.
  • the disadvantage of such an arrangement is that the fingers of the lugs can easily be bent in which case the arm becomes detached from the base. Also, the bending of the fingers is awkward because they are relatively small and inaccessible.
  • a compressor bar of the type specified above in which the said arm is pivotally attached to the base to pivot about an axis extending in the same general direction as the said longitudinal direction between the openings in the base.
  • the arm that includes the flexing means is preferable pivotally attached to one of the rods to move between the first and second positions.
  • the flexing means comprises a bore through which the rod passes.
  • the flexing means preferably includes a cam surface that, when pressed into the space between the rods, urges them apart and so flexes them.
  • the flexing means my also include a further surface that maintains the rods in a stable arrangement in which they are in their flexed state.
  • lever arch mechanism of a document file having prongs 10 that form a closed loop with arched sections 12.
  • the arched sections can be separated from the prongs 10 by movement of lever 14 to allow documents to be removed from the prongs and/or new document to be inserted on the prongs.
  • Figure 1 also shows the compressor bar 16 of the present invention.
  • the compressor bar includes a base 17 having two openings 18 through which the prongs of the file pass. Also visible in Figure 1 are rods 20' and 20'' extending most of the length of the base 17 (as will be described in further detail below) and in particular are located on either side of each of openings 18.
  • An arm 22 is also provided that moves the rods 20' and 20'' between a position in which they clamp the prongs 10 between them and a second position (shown in Figure 1) in which they do not clamp the prongs and therefore the bar 16 is freely movable on the prongs.
  • Documents 24 are installed within the file.
  • the margins of the documents have two holes punched in them and they are held in the file by the prongs 10.
  • the compressor bar 16 grips the prong and so compresses the documents within the file. The mechanism of the compressor bar will be described in further detail below.
  • the compressor bar having a base 17, which will generally made of pressed steel.
  • the base has a flat bottom rim 26 that engages the document (see Figure 1).
  • Within the base are a pair a spaced-apart rods 20' and 20'' (see Figure 2b in particular) that extend between and across the openings 18.
  • the rods are held centrally by two collars 28 and the ends of the rods are supported on ledges 30.
  • Two sets of lands 32 are provided adjacent to the openings 18 that engage respectively the sides of the rods 20' and 20''.
  • the collars 28, the ledges 30 and the lands 32 can all be pressed out from the same sheet material as is used to form the base 17.
  • Arm 22 has a bore 23 in a boss 25 (see in particular Figure 6) that is integrally formed with crosspiece 27.
  • the arm is in the form of a rocker and the boss 25 has an end-face 29 and a bevel face 31.
  • the two rods 20' and 20'' are parallel to each other, and, in the windows 18, the spacing is greater than the diameter of the prongs 10 of the document file.
  • the compression bar can easily be moved up and down the prongs and removed altogether from the prongs.
  • the boss 25 is positioned within a central opening 36 in the base 17 and one of the rods 20' passes through the bore 23 in the boss 25, thereby allowing the arm to pivot about that rod.
  • the arm pivots about the bore 23 and the rod 20' on which it is engaged.
  • This pivoting motion presses the bevelled face 31 of the boss against the other rod 20'', causing the centres of the rods to be moved outwardly away from each other until eventually the rods are sufficiently far apart that the edge 43 passes over the rod 20'' and the end face 29 is brought into contact with the rod 20''.
  • the tension in the rods 20' and 20'' keeps the rod 20'' in engagement with end face 29 and such an arrangement in stable.
  • the separation between the rods 20' and 20'' in the openings 18 when the arm 22 is in the position shown in Figures 3a and 3b is less than the diameter to the prongs 10 of the file.
  • the rods 20' and 20'' will therefore grip the prongs and prevent the compressor bar (and any underlying documents) from moving.
  • the base also includes a spacer 62 (see Figure 6) that prevents the separation between the rods falling below a minimum when they are in their unflexed state.
  • spacer 62 prevents the rods from falling out and also maintains sufficient spacing in the region of the openings 18 to allow the prongs of the file 10 to move freely through the openings 18 without being obstructed by the rods.
  • the base 17 and the arm 22 can each separately be made from pressed metal sheets although the arm 22 may be cast metal, although is preferably it is made of moulded plastic.
  • the rods 20' and 20'' are of standard resilient steel.
  • FIGS 7 to 10 Alternative versions of the arm are shown in Figures 7 to 10, which use the same reference numerals as in Figures 5 and 6 to show corresponding features.
  • the arms of Figures 7 to 10 work in exactly the same manner as the arm of Figures 5 and 6 and differ only in their detailed shapes ad the fact that they are made from pressed metal, as opposed to the arm of figures 5 and 6, which is made from plastics material.
  • the advantage of the bar of the present invention is that it is more robust than the prior art arrangement and the pivot about which the rocker arm pivots is stronger and so the arm cannot easily become detached from the base. Also, the assembly of the bar of the present invention is easier than in the prior art arrangement.
