Definitions

  • This invention relates to a paper-retaining mechanism and, in particular, such a mechanism which is securable to a substrate to form a paper-retaining device, such as a box file or document holder, and a paper-retaining device incorporating such a mechanism.
  • a conventional paper-retaining mechanism is fixedly secured to a substrate (e.g. a box file cover or document holder cover) for releasably retaining sheets of hole-punched paper or similar material.
  • a one-armed lever is pivotable to pivot a pair of arches relative to a pair of fixed posts to allow pieces of hole-punched paper to be retrieved from or inserted into the file mechanism, and for closing the posts and arches to form a pair of closed rings to retain the paper therein.
  • the pair of arches are joined with each other by an intervening crank on which a roller attached to the lever travels during pivotal movement of the lever, to selectively effect opening or closing of the pair of rings.
  • the lever is pivoted downwardly to close the ring pairs formed by the posts and arches and is pivoted upwardly to allow a spring leaf to pivot to thereby open the rings.
  • a problem associated with such a conventional lever-arch type file mechanism is that when the lever is pivoted to an upper position to open the rings, the lever is in contact with or is at least very close to an underside of one of the arches, such that paper can only be inserted into or retrieved from the posts, but cannot be inserted into or retrieved from the arches.
  • a paper-retaining mechanism including a generally planar base, at least two post members secured to said base, at least two arch members joined with each other for simultaneous movement, wherein said arch members are movable relative to said post members between a closed position in which said arch members are in contact with said post members to form two closed rings and an open position in which said arch members are out of contact with said post members wherein said rings are open, a lever with an operating end, said lever being pivotable between a first position to move said arch members to said closed position and a second position to move said arch members to said open position, and spring means biasing said arch members to said open position; characterized in that said operating end of said lever is between said rings when said lever is in said first position and in said second position.
  • a A paper-retaining device including a substrate and a paper-retaining mechanism engaged with said substrate, said paper-retaining mechanism including a generally planar base, at least two post members secured to said base, at least two arch members joined with each other for simultaneous movement, wherein said arch members are movable relative to said post members between a closed position in which said arch members are in contact with said post members to form two closed rings and an open position in which said arch members are out of contact with said post members wherein said rings are open, a lever with an operating end, said lever being pivotable between a first position to move said arch members to said closed position and a second position to move said arch members to said open position, and spring means biasing said arch members to said open position; characterized in that said operating end of said lever is between said rings when said lever is in said first position and in said second position.
  • Figs. 1 to 5 show various views of a lever-arch type file mechanism according to an embodiment of the present invention, and generally designated as 10.
  • the mechanism 10 includes a generally planar base 12 and a support plate 14 extending upwardly away from the base 12.
  • the support plate 14 is fixedly joined with the base 12.
  • the support plate 14 may be stamped out from a same sheet of metal from which the base 12 is formed.
  • Two posts 16 are fixedly secured to the base 12.
  • a pair of arch members 18 are integrally formed and joined with each other via an intermediate portion 20, so that the arch members 18 and the intermediate portion 20 are movable simultaneously with one another.
  • the arch members 18 are engaged with the base 12 by claws 22, so that the arches 18 are pivotable relative to the posts 16 and the base 12 between a first position (called the “closed position") in which free ends 18a of the arch members 18 and free ends 16a of the posts 16 are in contact and mate with each other to form two closed rings (wherein the paper-retaining mechanism 10 is said to be in a "ring-closed configuration") and a second position (called the "open position") in which the free ends 18a of the arches 18 and the free ends 16a of the posts 16 are out of contact with each other, so that the rings are open (wherein the paper-retaining mechanism 10 is said to be in a "ring-open configuration").
  • a spring plate 24 is engaged with the base 12 so that it acts on the intermediate portion 20 from below, to bias the arch members 18 to the open position.
  • the lever-arch type file mechanism 10 includes a lever 26 with a first body portion 26a and a second body portion 26b which are joined with each other, e.g. by formed integrally with each other.
  • Various views of the lever 26 are shown in Figs. 6 to 10 .
  • An angle ⁇ (see Fig. 6 ) between the first body portion 26a and the second body portion 26b of the lever 26 is over 90°, such as between 110° to 150°, and preferably 130°.
  • the first body portion 26a has an operating free end 28 which is manually operable to move the lever 26 to move the lever-arch type file mechanism 10 between the open configuration and the closed configuration, in a manner to be discussed below.
  • the lever 26 is engaged via a rivet 30 to the support plate 14 whereby the lever 26 is pivotable relative to the support plate 14 about an axis P-P which is parallel to the base 12.
  • the rivet 30 is engaged via a hole 38 through the second body portion 26b of the lever 26.
  • a roller 32 is engaged with the second body portion 26b of the lever 26 via a rivet 34 which allows the roller 32 to be freely rotatable relative to the second body portion 26b of the lever 26.
  • the roller 32 acts on a cranked portion 20a of the intermediate portion 20 to keep the free ends 18a of the arch members 18 in contact with the free ends 16a of the posts 16, and thus to keep the lever-arch type file mechanism 10 in the ring-closed configuration, against the biasing action of the spring plate 24.
  • the first body portion 26a of the lever 26 is on the right side (in the sense of Fig. 1 ) of an axis T-T perpendicular to the base 12, and is inclined relative to the axis T-T by an angle ⁇ of 20° to 50°; and preferably 30°.
  • the lever 26 is pivoted relative to the support plate 14 about the axis P-P in the direction indicated by the arrow C (see Fig. 1 ) to the position as shown in Figs. 13 and 14 , in which the first body portion 26a of the lever 26 is on the other side (i.e. left side in the sense of Fig. 1 ) of the axis T-T, and is inclined relative to the axis T-T by the same angle ⁇ of 20° to 50°, and preferably 30°.
  • the lever-arch type file mechanism 10 may be fixedly or detachably secured, e.g. by rivets or screws, to a substrate (e.g. a box file folder) made of metal, metal alloy, cardboard or the like, to form a paper-retaining device.
  • a substrate e.g. a box file folder
