Description
- 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.
- In a conventional lever-arch type file mechanism, 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.
- In such a conventional file mechanism, a resilient spring leaf is provided under the intervening part joining the arches for biasing the intervening part. 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. Various proposals to reduce the material for, and thus production cost of, lever-arch type file mechanisms have been made.
- It is an object of the present invention to provide a lever-arch type file mechanism and a paper-retaining device in which the material and production cost are reduced, or at least to provide a useful alternative to the trade and public.

Fig. 18D is a top perspective view of the resilient wire shown inFig. 18A . - A lever-arch file type mechanism according to a first embodiment of the present invention is shown in
Figs. 1A to 1E , and generally designated as 100. As shown more clearly inFigs. 2 to 4 , themechanism 100 includes a base 102 formed of a metal sheet. Fourholes 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 themechanism 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. - Two
upstanding posts 106 are fixedly engaged, each via ahole 108, with thebase 102. Themechanism 100 includespivotable component 110 with twoarches 112 joined by abent intervening part 114. Thepivotable component 110 is engaged by twoclamps 116 on thebase 102 for pivotal movement about the base 102 about an axis T-T, which is parallel to amajor side 118 of thebase 102. In the configuration shown inFigs. 3 and4 , theposts 106 and thearches 112 of thepivotable component 110 mate with each other to form a pair of closed rings. - The
base 102 has a central generallyupstanding plate 120, which is integral with thebase 102, and may be stamped out of the same metal sheet with which thebase 102 is made. Adjacent an upper end of theplate 120 is provided with ahole 122 for pivotally engaging with alever 124 via arivet 126. Thelever 124 carries, via apin 128, aroller 130 for free rotation. When assembled, theroller 130 rides on and along a central portion of the interveningpart 114 of thepivotable 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 (seeFig. 10C ). As can be seen more clearly inFigs. 10A to 10D , thewire 132 has ahead portion 134 with two adjoiningportions 136 which are non-parallel to each other. Each of theportions 136 is joined with arespective end portion 138 via a respective steppedportion 140. - The two
end portions 138 lie on a same straight line W-W and are parallel to thehead 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 thewire 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 theresilient 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 adjoiningportions 136 are parallel with each other. - Returning to
Figs. 2 to 4 , thewire 132 is engaged with the base 102 by having the twoend portions 138 inserted into aslot 142 of thebase 102, so that thewire 132 is pivotable relative to the base 102 about the axis W-W passing through theend portions 138. When thewire 132 is thus assembled with thebase 102, the axis W-W is parallel to the axis T-T about which thepivotable component 110 is pivotable about thebase 102. - When the
lever 124 is pivoted upwardly from the position as shown inFigs. 5A to 5D to that as shown inFigs. 6A to 9D , theroller 130 is pivoted away and upwardly from its lowest position shown inFigs. 5A to 5D , whereupon theresilient wire 132 pivots upwardly about the axis W-W, to act on the interveningpart 114 from below, so as to cause thepivotable component 110 to pivot away from theposts 106, to open the pair of rings. In particular, the adjoiningportions 136 abut the interveningpart 114 from below and, by reason of their resilience, bias thearches 112 away from theposts 106. -
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-archfile type mechanism 200 is similar to that of the lever-archfile type mechanism 100, with the main difference being the shape of aresilient wire 232. - As shown more clearly in
Figs. 14A to 14D , theresilient wire 232 has ahead portion 234 with an adjoiningportion 236 on each side, in which the two adjoiningportions 236 are non-parallel with each other. Each of the two adjoiningportions 236 is joined with arespective end portion 238 via anintermediate portion 240. Theend portions 238 lie on a same line M-M, which also acts as the pivotal axis when thewire 232 is installed in themechanism 200. It can be seen that there are eight turning points along thewire 232, namely B1, B2, B3, B4, B5, B6, B7 and B8. Of these turning points, B1 and B8 are of 90°, B4 and B5 are less than 90°, and B2, B3, B6 and B7 are U-turns, i.e. of 180°. Alternatively, theresilient 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 adjoiningportions 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-archfile type mechanism 300 is similar to that of the lever-archfile type mechanisms resilient wire 332. - As shown more clearly in
Figs. 18A to 18D , theresilient wire 332 has ahead portion 334 with an adjoiningportion 336 on each side, in which the two adjoiningportions 336 are parallel with each other. Each of the two adjoiningportions 336 is joined with arespective end portion 338. Thehead portion 334 is parallel with theend portions 338, which lie along a same line P-P, which also acts the pivoting line when thewire 332 is installed in thefile mechanism 300. It can be seen that there are four generally perpendicular (90°) turning points, namely C1, C2, C3, C4, along thewire 332. Theresilient 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 adjoiningportions 336 are non-parallel with each other. - It should be understood that the above only illustrates examples whereby the present invention may be carried out, and that various modifications and/or alterations may be made thereto without departing from the spirit of the invention.
- It should also be understood that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may be provided in combination in a single embodiment. Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any appropriate sub-combinations.
