Abstract
A lever-arch type file mechanism (100, 300, 400, 500) is disclosed as including a base (102), two rings secured to and extending upwardly from the base for engaging holes in pieces of paper, each ring including a post (106, 306) fixed to the base and an arch (128, 328) movable relative to the base and the post; and a lever (108, 308) operable to move the arches relative to the posts between a closed configuration in which the rings are closed and an open configuration in which the rings are open; the arches being joined by an intervening part (126, 336, 436, 536) including a support piece (130, 330, 430, 530) engaged with a body part (136, 336, 456, 550).
Description
- This invention relates to a device for retaining a stack of hole-punched paper in a file and, in particular such a device comprising a lever-arch type file mechanism.
- In most existing lever-arch type file mechanisms, a one-armed lever is provided for pivoting a pair of arch elements relative to a pair of fixed posts to allow pieces of hole-punched paper to be retrieved from or inserted into the file mechanisms, and for closing the posts and arch elements to form a pair of closed rings to retain the paper therein. The pair of arch elements are integrally formed with, and joined with, each other by a bent portion on which a roller attached to the lever travels during pivotal movement of the lever, to effect opening or closing of the ring pairs.
- When the ring pairs are open, the upper free end of the lever is very close to, and sometimes abuts, one of the arch elements. Thus, when the ring pairs are open, paper can only be retrieved from or inserted into the pair of fixed posts, but no paper can be retrieved from or inserted into the pair of pivotable arch elements.
- One possible way of overcoming this problem is to so shape the bent portion that the arch elements will fully pivot upon pivotal movement of the lever by a smaller angle of rotation. This means that there will be an abrupt downward bend along the part of the bent portion along which the roller travels. Conventional arch elements and the intervening bent portion are formed integrally of a metal. It is found in practice that it is difficult to form the required abrupt bend in this metal part.
- It is thus an object of the present invention to provide a lever-arch type file mechanism and a lever-arch type file in which the aforesaid shortcomings are mitigated, or at least to provide a useful alternative to the public.
- According to a first aspect of the present invention, there is provided 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; and a lever operable to move said arch members 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; wherein said arch members are joined by an intervening part; characterized in that said intervening part includes at least a first part and a second part engaged with each other.
- According to a second aspect of the present invention, there is provided a lever-arch type file including a lever-arch type file mechanism fixedly engaged with a substrate, wherein said lever-arch type file mechanism includes 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; and a lever operable to move said arch members 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; wherein said arch members are joined by an intervening part; characterized in that said intervening part includes at least a first part and a second part engaged with each other.

Figs. 1A to 1E , and generally designated as 100. As shown more clearly inFigs. 2 to 4 , themechanism 100 includes a generallyflat base 102 with anupstanding wall 104 extending from and generally perpendicular to thebase 102. Thewall 104 is integrally formed with thebase 102, e.g. be stamped and bent out from a same metal sheet. Twoposts 106 are fixedly engaged with, and are thus not movable relative to, thebase 102. - A hand-operated
lever 108 has a free operatingfirst end 110 and asecond end 112 which is engaged via arivet 114 to thewall 104 for allowing pivotal movement of thelever 108 relative to thewall 104 about therivet 114. Thelever 108 carries, via apin 116, aroller 118, the function of which will be discussed below. - A
resilient spring leaf 120 has afirst side 122 which is engaged with thebase 102, and an oppositesecond side 124 which acts on an under side of an interveningportion 126 between and joining twoarch portions 128. Asupport piece 130, which may be made of a plastics material, such as polyoxy methylene, is fixedly engaged with abody part 136 of the interveningportion 126 at its mid-point. Alternatively, thesupport piece 130 may be made of the same metal material with which thebody part 136 is made. - When assembled, and as shown in
Figs. 2 to 4 , theroller 118 rides on and can travel along an upper edge of thesupport piece 130. As shown also inFigs. 5 to 7 , thesupport piece 130 is fixedly engaged with thebody part 136 of the interveningportion 126. In the configuration shown inFigs. 2 to 7 , theposts 106 andarch portions 128 mate with each other to form two closed rings, e.g. for retaining pieces of hole-punched paper (not shown). In this closed configuration, thelever 108 is at its lower position, and theroller 118 is at a stable position on ahigher edge portion 132 of anupper edge 160 of thesupport piece 130. - Upon upward pivotal movement of the
lever 108 to the position shown inFigs. 8A to 12 , theroller 118 is pivoted away from its lower position to its upper position. As the interveningportion 126 is held in place by twoclaws 134, thespring leaf 120 urges and pivots the interveningportion 126, causing thearch portions 128 to pivot away from theposts 106 to the position shown inFig. 8B , in which the ring pairs are open, thus allowing pieces of hole-punched paper to be inserted into or retrieved from theposts 106 and/or thearch portions 128. In this configuration, theroller 118 rests in a second stable position which is at the lowest point of alower edge portion 140 of thesupport piece 130. - As shown in
Figs. 13A and 13B , thesupport piece 130 is fixedly engaged with aflat portion 138 mid-point of thebody part 136 which is integrally formed with thearch portions 128. As shown more clearly inFig. 14A , the upper edge of thesupport piece 130 includes thehigher edge portion 132 and an adjoininglower edge portion 140, in which the slope of the part of thelower edge portion 140 adjoining thehigher edge portion 132 is steeper than that of thehigher edge portion 132. It is also so arranged that the horizontal distance travelled by theroller 118 between the first and second stable positions is within 8.5mm, and the vertical distance between the highest point of thehigher edge portion 132 and the lowest point of thelower edge portion 140 is more than 4.5mm. - It is found in practice that, by way of such an arrangement, the
arch portions 128 can be fully pivoted away from theposts 106 to open the ring pairs, whereas thelever 108 is not positioned too close to thearch portions 128, as can be seen more clearly inFigs. 8A and9 . Such an arrangement allows pieces of hole-punched paper to be inserted into or retrieved from thearch portions 128 and theposts 106, thus enhancing convenience of use of themechanism 100. - The lever-arch
type file mechanism 100 may be fixedly engaged, e.g. by rivets, to a substrate, e.g. a cardboard cover, to form a lever-arch type file. - A lever-arch type file mechanism according to a second embodiment of the present invention is shown in
Figs. 15A to 20 , and generally designated as 300. A major difference between thismechanism 300 and themechanism 100 discussed above is that, in themechanism 300, alever 308 is pivoted from its upper position as shown inFig. 15A downwardly (i.e. in the direction indicated by the arrow A shown inFig. 15A ) to a lower position as shown inFig. 18A , to pivotarch portions 328 away fromposts 306 to open the ring pairs, as shown inFigs. 18A to 20 . - In the lever-arch
type file mechanism 300, the twoarch portions 328 are integrally formed with abent body part 336 at or adjacent the mid point of which aplastics support piece 330, which may be made of polyoxy methylene, is fixedly engaged. Alternatively, thesupport piece 330 may be made of the same metal with which thebody part 336 is made. In thismechanism 300, the orientation of thesupport piece 330 is opposite to that of thesupport piece 130 in themechanism 100. - A lever-arch type file mechanism according to a third embodiment of the present invention is shown in
Figs. 21 to 25 , and generally designated as 400. A major significant feature in themechanism 400 is that asupport piece 430 is snap-fitted with abody 450 of an interveningpart 436. - As shown more clearly in
Figs. 26A to 27D , thebody 450 of the interveningpart 436 has twoelongate end portions 452 and an off-setflat portion 454. Theportion 454 has tworectangular holes 456, each for receiving arespective hook 458 of thesupport piece 430, as shown inFigs. 28A to 28E . Thepiece 430 may be made of a plastics material, e.g. polyoxy methylene, or a metal. Thehooks 458 are inherently resilient, and may be received through and snap-fitted with theholes 456 for fixedly engaging thesupport piece 430 with thebody 450 of the interveningpart 436, as shown inFigs. 26A and 26B . The remaining part of the interveningpart 436, such as thebody 450, theend portions 452 and theflat portion 454 may also be made of a plastics material, or of a metal. - A lever-arch type file mechanism according to a fourth embodiment of the present invention is shown in
Figs. 29 to 33 , and generally designated as 500. Thismechanism 500 is structurally similar to themechanism 400 discussed above. A major different feature in themechanism 500 is that asupport piece 530 is fixedly engaged with aflat portion 552 of abody 550 of an interveningpart 536 by a pair ofrivets 540. Again, thesupport piece 530 and thebody 550 may each be made of a metal or a plastics material. - 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.
