Definitions

  • the present invention relates to a device for retaining a stack of papers in a file, for example a lever arch mechanism for a lever arch file.
  • Lever arch files are well known for retaining a stack of papers in a file. They generally include a base, two rings secured to, and extending upwardly from, the base for engaging holes in the margin of the stack of paper. Each ring is composed of a first section for holding the papers when the file is closed and a second, arched section and a mechanism for holding the first and second sections in a closed position to form a closed loop, and an open position in which the first and second sections are separated to allow papers to be added to, or removed from, the rings. In the first position, papers on top of a stack of papers held in a file can be slid over the rings to allow papers further down the stack to be easily consulted.
  • the present invention is based on the realisation that the greatest damage to the papers occurs when the rings are closed, e.g. when the file is closed and is dropped, and the extra robustness provided when there are four rings is not in practice required when the rings are open. This allows many of the disadvantages of the four ring device to be eliminated or at least reduced while still maintaining its most significant advantage.
  • a device for retaining a stack of papers that have holes in their margins in a file which device comprises:
  • the device is a so-called "lever arch file” in which the arched section of each ring is pivotally mounted and the mechanism includes means, for example, a lever, for urging the arched section into the closed position and a spring that urges the arched second section into the open position when the lever is released.
  • the pins may be straight or curved.
  • the pins that form part of the rings and the additional pins are preferably all identically shaped.
  • the additional pins are preferably provided between the rings.
  • the present invention holds the papers on three or more pins and so it is harder for a sheet of paper to be torn out of the file by accident, e.g. on dropping the file, when the papers are engaged on all the pins and so provides the additional robustness of the known four-ring device described above.
  • the present invention avoids the complexity of the opening and closing mechanism of the known four-ring device; for example in the arrangement of the present invention that is equivalent to the known four-ring device has two rings and two additional pins.
  • the mechanism to open and close the rings only has to operate on two rings since the additional pins do not have corresponding arched sections whereas the mechanism of the known four-ring device has to operate on four rings.
  • the mechanism is simpler, lighter and cheaper in the present invention than in the corresponding known four-ring arrangement in which every pin forms a closed loop with a corresponding arched section.
  • the device for retaining a stack of papers in a file.
  • the device includes a base 10 made from pressed steel and including 'holes 12 that accommodate rivets (not shown) for securing the device to a file.
  • Two rings 14 extend from the base 10, each ring being composed of a pin 16 and an arched section 18. Additional pins 20 are secured to the base 10 between the rings 14.
  • the pins 16 and 18 pass through holes 19 in the base 10 (see Figure 4) and are welded in place on the base 10.
  • the arched sections 18 of the two rings 14 are joined together by a central section 30, which is pivotally held on the base by two bent over tabs 31, which are pressed out from the base 10. Such an arrangement allows the arched sections 18 and the connecting part 30 to pivot about a horizontal axis extending between the two tabs 31.
  • the connecting section 30 includes a crank section 32.
  • a leaf spring 34 is secured at one end (34') in a slot 36 in the base; the other end 34" engages underneath the crank section 32 and tends to urge the crank section 32 upwardly, causing the arched sections 18 to pivot about the horizontal axis extending between the two tabs 31 to open the rings.
  • a generally upright wall 40 is also pressed out from the base 10.
  • a lever 42 is secured to the wall 40 by means of a rivet 44 that passes through a hole 46 in the wall 40 and a hole 48 in the lever 42.
  • the arrangement is such that the rivet 44 allows the lever 42 to pivot about the wall 40.
  • the lever 42 carries a roller 50 that is secured to it by a further rivet 52 whose end is secured in a hole 54 in the lever 42.
  • the roller engages the top of the crank section 32 to control the opening and clothing of the arched section 18 of the ring 14, as will be described later.
  • the tops of the pins 16 have a male profile 60 that mate with a corresponding female profile at the end 62 of the arched sections 18 (see Figure 4); this allows a positive engagement between the pin 16 and the arched section 18 of each ring 14 and assists the alignment between the pin 16 and the arched section 18 of each ring so that paper cannot snag on the join between them.
  • the lever 42 can be moved about rivet 44 between a horizontal position (shown in Figure 1) and an upwardly extending position shown in Figure 2.
  • the roller 50 presses the crank section 32 down against the action of the spring 34 to keep the arched sections 18 of each ring in the locked position abutting against the corresponding pins 16 to form the closed rings shown in Figure 1.
  • the roller 50 no longer presses down on the crank section 32 and this allows the crank section 32 to be moved upwardly by spring 34 into the open position shown in Figure 2.
  • the crank section 32 can be moved by the roller 50 against the action of the spring 34 into the closed position shown in Figure 1.
  • a stack of papers 22 (shown In Figure 3) having holes (not shown) in their margins can be threaded onto the pins 16 and the additional pins 20 when the rings are in their "open” position (shown in Figure 2).
  • the lever 42 can be depressed to the position shown in Figure 1 to hold the stack of papers captive on the rings 14.
  • the upper pages of the stack may be slid over the pins 16, 20 and retained on the arched sections 18 so that papers lower down the stack can be exposed for easy reading.
  • a document compressor bar 24 may also be threaded onto the pins 16 and 20 and includes openings 29, 31 through which the pins 16, 20 can pass.
  • the bar includes rods 26 that grip the pins 16 when a button 28 is depressed and release the pins 16 when the button is raised. The bar thus holds the papers in place and prevents them sliding up and down the pins 16 and 20 when the button 28 is depressed (i.e. when the rods grip the pins 16) but the bar allows the papers to slide freely on the pins when the button is raised and the rods release their grip on the pins 16.
  • the bar 24 differs from a conventional compressor bar in having the additional holes 29 to accommodate the additional pins 18; the pins 16 pass through the holes 31.
