Definitions

  • This invention relates to a lever-arch type file mechanism, in particular such a mechanism adapted to be affixed to a substrate, e.g. a cardboard, to form a device for retaining pieces of hole-punched paper.
  • a substrate e.g. a cardboard
  • a one-armed lever is provided for selectively pivoting a pair of arches relative to a pair of fixed posts to open a pair of rings formed by the arches and posts, to allow pieces of hole-punched paper to be retrieved from or inserted into the file mechanism, and to close 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 shaped part on which a roller attached to the lever travels during pivotal movement of the lever, to effect opening or closing of the ring pairs.
  • a resilient spring leaf is provided under the intervening part joining the arches for biasing the intervening part.
  • the resilient spring leaf Upon pivotal movement of the lever, the resilient spring leaf is allowed to pivot upwardly to pivot the pair of arches relative to the pair of posts to open the ring pairs.
  • a lever-arch type file mechanism including a base; at least two rings secured to and extending upwardly from the base for engaging holes in at least a piece of paper, each said ring including a post member fixed to said base and an arch member movable relative to said base and said post member; a lever operable to pivot said arch members about an axis and relative to said post members between a closed configuration in which said rings are closed and an open configuration in which said rings are open; and an intervening part joining said arch members; characterized in including a resilient wire abutting said intervening part, and wherein, during pivotal movement of said arch members relative to said post members, said resilient wire is pivotable about an axis substantially parallel to said pivotal axis of said arch members.
  • a paper-retaining device including a lever-arch type file mechanism fixedly engaged with a substrate, said device including a base; at least two rings secured to and extending upwardly from the base for engaging holes in at least a piece of paper, each said ring including a post member fixed to said base and an arch member movable relative to said base and said post member; a lever operable to pivot said arch members about an axis and relative to said post members between a closed configuration in which said rings are closed and an open configuration in which said rings are open; and an intervening part joining said arch members; characterized in including a resilient wire abutting said intervening part, and wherein, during pivotal movement of said arch members relative to said post members, said resilient wire is pivotable about an axis substantially parallel to said pivotal axis of said arch members.
  • a lever-arch file type mechanism is shown in Figs. 1A to 1E , and generally designated as 100.
  • the mechanism 100 includes a base 102 formed of a metal sheet.
  • Four holes 104 are provided on the base 102 through each of which a securing element, e.g. a rivet (not shown) may be received for fixedly engaging the mechanism 100 to a substrate, e.g. a writing board or a cardboard file cover, to form a device for retaining pieces of hole-punched paper, e.g. a lever-arch file type.
  • a substrate e.g. a writing board or a cardboard file cover
  • the mechanism 100 includes pivotable component 110 with two arches 112 joined by a bent intervening part 114.
  • the pivotable component 110 is engaged by two clamps 116 on the base 102 for pivotal movement about the base 102 about an axis T-T, which is parallel to a major side 118 of the base 102.
  • T-T axis
  • the base 102 has a central generally upstanding plate 120, which is integral with the base 102, and may be stamped out of the same metal sheet with which the base 102 is made. Adjacent an upper end of the plate 120 is provided with a hole 122 for pivotally engaging with a lever 124 via a rivet 126.
  • the lever 124 carries, via a pin 128, a roller 130 for free rotation. When assembled, the roller 130 rides on and along a central portion of the intervening part 114 of the pivotable component 110.
  • a resilient wire 132 which may be made integrally of a metal, a metal alloy, or a plastics material, is bent symmetrically about a longitudinal axis S-S (see Fig. 10C ). As can be seen more clearly in Figs. 10A to 10D , the wire 132 has a head portion 134 with two adjoining portions 136 which are non-parallel to each other. Each of the portions 136 is joined with a respective end portion 138 via a respective stepped portion 140.
  • the two end portions 138 lie on a same straight line W-W and are parallel to the head portion 134. It can be seen that there are eight turning points A1, A2, A3, A4, A5, A6, A7 and A8 along the length of the wire 132. Of these turning points, A1, A2, A7 and A8 are each of 90°, and A3, A4, A5 and A6 are less than 90°. It is possible to form the resilient wire 132 such that the turning points A1, A2, A7 and A8 are less than 90° and the turning points A3, A4, A5 and A6 are each of 90°, in which case the two adjoining portions 136 are parallel with each other.
  • the wire 132 is engaged with the base 102 by having the two end portions 138 inserted into a slot 142 of the base 102, so that the wire 132 is pivotable relative to the base 102 about the axis W-W passing through the end portions 138.
  • the axis W-W is parallel to the axis T-T about which the pivotable component 110 is pivotable about the base 102.
  • Figs. 11A to 13 show various views of a lever-arch file type mechanism according to a second embodiment of the present invention, generally designated as 200.
  • the structure of the lever-arch file type mechanism 200 is similar to that of the lever-arch file type mechanism 100, with the main difference being the shape of a resilient wire 232.
  • the resilient wire 232 has a head portion 234 with an adjoining portion 236 on each side, in which the two adjoining portions 236 are non-parallel with each other.
  • Each of the two adjoining portions 236 is joined with a respective end portion 238 via an intermediate portion 240.
  • the end portions 238 lie on a same line M-M, which also acts as the pivotal axis when the wire 232 is installed in the mechanism 200. It can be seen that there are eight turning points along the wire 232, namely B1, B2, B3, B4, B5, B6, B7 and B8.
  • B1 and B8 are of 90°
  • B4 and B5 are less than 90°
  • B2, B3, B6 and B7 are U-turns, i.e. of 180°.
  • the resilient wire 232 may be formed such that the turning points B1 and B8 are less than 90° and the turning points B4 and B5 are each of 90°, in which case the two adjoining portions 236 are parallel with each other.
  • Figs. 15A to 17 show various views of a lever-arch file type mechanism according to a third embodiment of the present invention, generally designated as 300.
  • the structure of the lever-arch file type mechanism 300 is similar to that of the lever-arch file type mechanisms 100, 200, with the main difference being the shape of the resilient wire 332.
  • the resilient wire 332 has a head portion 334 with an adjoining portion 336 on each side, in which the two adjoining portions 336 are parallel with each other.
  • Each of the two adjoining portions 336 is joined with a respective end portion 338.
  • the head portion 334 is parallel with the end portions 338, which lie along a same line P-P, which also acts the pivoting line when the wire 332 is installed in the file mechanism 300.
  • P-P which also acts the pivoting line when the wire 332 is installed in the file mechanism 300.
  • the resilient wire 332 may also be formed such that the turning points C1, C2, C3 and C4 are all less than 90°, in which case the adjoining portions 336 are non-parallel with each other.
