This invention is related with articles for the preservation of documents, of the type of portfolios and ringed portfolios or fastening portfolios or similar, in which a device or element for subjection maintains in their place and protect the documents in its interior.
Articles for preservation of groups of loose leaves or files, such as briefcases and portfolios are thoroughly well-known for public in general, and they are made in a wide variety of forms and materials such as paper (see U.S. Pat. No. 4,934,584 (Wyant, 1990), and U.S. Pat. No. 3,516,599 (Buttery, 1970)), plastic (we mention U.S. Pat. No. 5,876,143 (Ong, 1999), U.S. Pat. No. 5,059,052 (Casper, 1991), U.S. Pat. No. 5,752,721 (Balbas, 1998) and U.S. Pat. No. 5,417,509 (Schwartz, 1995)), the employment of vinyl is illustrated in U.S. Pat. No. 5,873,513 (Ong, 1999) and U.S. Pat. No. 4,629,349 (Pitts, 1986); articles made of polyethylene, polypropylene and PVC are illustrated in the U.S. Pat. No. 5,275,438 (Struhl, 1994), U.S. Pat. No. 5,445,417 (Bromer, 1995) and U.S. Pat. No. 5,266,140 (Kohno, 1993).
Most frequently used articles are constituted by a front cover and a back cover and, in the case of the so called “portfolios” a dorsal ribbon or “loin” between both covers, with which forms a “hinge” in order to open and close them and so permitting the insertion or retirement of the documents.
Conventionally front and back covers are made of plane wide panels with lightly larger dimension to those of the standard paper sizes used in the offices and home, for example letter, legal, A4, etc.; the dorsal ribbon usually is narrower by much and it is in function of the thickness associated with the amount of leaves that is destined to the article; in the case of the folders destined to conserve groups of relatively few leaves in their interior, normally this ribbon or loin does not exist.
In the articles of the prior art, diverse alternatives in order to provide security in the integrity of the documents have been proposed. These range from the employment of mechanical elements of subjection such as hoops, rings, fastenings and staples, where the material to hold should be perforated in corresponding places to positions predetermined by the own device from subjection, or, pressure fastenings, paper clips or other prehensile elements, preset preferably to the back panel of the folder, briefcases or portfolio.
In a different way of the first, pressure fastenings significantly reduce damage to the material to preserve, although they use to leave marks in the points of contact with this.
Another solution has been the incorporation of additional panels subject to the interior surfaces of one or both panels of the folder, the briefcase or portfolio, forming supports either in form of “lapel” or “pocket,” where the material is introduced to preserving.
The pockets, especially, could reach diverse heights in connection with the panel to which they are fixed, as described in the U.S. Pat. No. 5,059,052 (Casper, 1991), U.S. Pat. No. 5,752,721 (Balbas, 1998), U.S. Pat. No. 6,193,147 (Schluger, 2001) and U.S. Pat. No. 6,296,112 (Pettey, 2001).
The British patent GB-A-229997-1 (Penche, 1996), shows a development that allows to safeguard the documents that are placed in the interior of the stationery article of the type of a folder, being characterized by forming inferior bags by folding over and towards the interior of the folder, of individual projections from one or both panels of the folder, these folded projections are joined to the inner faces by their short sides. Note that in this article, both pockets formed in the inferior part of the folder are described only, and that this folder is a result of the opening of a mail envelope that is the matter of the invention. It is clear that once the article is transformed into a folder with inner inferior pockets, the edges and specially the upper corners of the documents contained inside, are exposed to deterioration by the inadvertent folding of the documents or by the inadvertent insertion of objects between both panels of the folder; the documents, also are exposed to fall out the interior of the folder when this one is turned upside down, because there is nothing that retains the documents in the interior.
In a simpler version of the concept of “lapels”, these are simple continuations of one or more ends of the panels that form the body of the folder, briefcase or portfolio, as illustrated in the U.S. Pat. No. 6,244,627 (Wolf, 2001) and U.S. Pat. No. 6,286,752 (Heyer, 2001).
It is important to notice that in all the cases referred above, the inferior edge and at least one of the two adjacent corners of the preserved document, are protected of the mistreatment by the “lapel” or “pocket” itself; however, the upper edge and the adjacent corners normally are free and they are subject to mistreatments by just opening and closing the panels of the folder, briefcase or portfolio, if it is not taken care to arrange by hand the leaves or the file upon closing the panels.
A pair of alternatives that attract attention for trying to overcome the problem, are represented by the inventions described in the U.S. Pat. Nos. 4,629,349 and 6,286,752. The first, offers a portfolio of rings with pockets joined with the internal surfaces of the panels, each pocket has a lapel that assures the documents preserved by means of a pressure fastening; the material (flexible and transparent) that conforms the pocket as such, is joined to the internal surfaces of the portfolio by means of thermo-sealing. In the second patent, U.S. Pat. No. 6,286,752, “tongues” are offered in order to support the material to preserving, being these, simple projections of the shortest sides (upper and inferior) of one of the panels of the folder, that upon bending toward the interior of such folder, allow to restrict in a certain grade, the movement of the material in its interior.
In order to overcome the difficulties found in the prior art, it is an object of this invention to offer an stationery article for the preservation of documents, of the type of portfolios, portfolios of rings or fastening portfolios or similar articles, that assure the integrity of the documents in its interior against mechanical mistreatment produced by the action of the covers or panels of the article itself.
It is another object of this invention that the assurance of the physical integrity of the documents is achieved in an economical and effective way for the addition of a device or element disposed for such objective, to a stationery article as briefcases or portfolios of rings or fastening portfolios, by using any of the well-known techniques in the art.
It is still another object of this invention, providing a stationery article in which mentioned device or fastening element does not interfere the view of the cover of the preserved documents, by being transparent or translucent.
It is still another object of this invention to provide a stationery article for the preservation of documents, in which the device or fastening element of the documents could bend without impede the use of the article as a briefcase or conventional portfolio, it is to say, it does not obstruct upon inserting the documentation in the article.
This invention will be understood better, from the detailed description that follows and from the accompanying drawings, which however, should not be taken as limits of the invention but as illustrative for its better understanding.
Next the stationery article (1) for the preservation of documents (5) is described, including the device or fastening element (6) that is the subject matter of this invention.
In a conventional portfolio of the prior art, such as that shown in the
It should be noticed that the upper end of the document normally has free movement toward front and back, as indicated by the double-headed arrow, with regard to the panel (2) or (3) in whose lapel (4) is been inserted; this movement is used to be restricted by the sole employment of means of mechanical subjection applied directly to the document, this is, additions like staples, paperclips or fastenings, that maintain the group of pages in a certain extension, however they do not protect in any way the edges and corners of the documents (5) at the top.
When, as shown in the
In order to avoid that upper edges of the documents (5), as well as the corners of the same, bend toward the front because the free movement that they provide, there is been provided, in the preferred embodiment of this invention, a device or fastening element like that shown in the
The form of the element (6), in the preferred embodiment of the invention, is essentially trapezoidal having the larger base of measure equals or lightly lesser to the interior measure of the panel (2) or (3) taken along the upper edge, opposite to the localization of the lapel or pocket (4) of support, and it is anchored to said upper edge of the interior surface of the panel (2) or (3) having the lapel or pocket of the prior art in its lowest part; the anchored is carried out by means of any well-known technique in the art, as weld by ultraviolet radiation, ultrasound, bond, thermo-sealed, sewn, etc., in function of the type of material that conforms the body of the panels of the article for the preservation of documents (5), either a portfolio, portfolio of rings, of fastening portfolio or similar, as long as the type of material selected for the fastening element (6) that is the subject matter of this invention, looking after that both materials are compatible in order to assuring a fixation of the fastening element (6) to the article under question.
The minor base of the trapeze goes toward the center of the panel (2) or (3), and it has the adjacent corners rounded with the purpose of avoiding any rip or scratch to the material that will be preserved in the folder or portfolio.
The union area between the fastening element (6) matter of the invention and the interior surface of the panel of the portfolio is located both, in the most external part of the surface of the fastening element (6) and that of the panel (2) or (3), being limited approximately for the A-A line as shown in
Considering again the
Upon release the fastening element (6), this recovers its normal position, and due to its relative rigidity and to the location of the area of union with the interior surface of the panel (2) or (3) of the portfolio, said element (6) exercises a pressure against the document toward the internal surface of the panel (2) or (3) of the portfolio, trapping so the upper edge of said document (5) in the form that is illustrated in the
As it have been mentioned above, if the material selected in order to elaborate the device or fastening element (6) matter of this invention is transparent, then said element (6) will not interfere with the possibility of viewing the content from the front page of the document (5) preserved, although this possibility is not restrictive of the invention every time the dimensions of the element are substantially lesser with regard to the area that is able to being covered by the material of the inferior support (lapel or pocket) (4).
Finally, it is clear that application of the fastening element (6) matter of this invention could be made, in the way it has been described, in one or both interior surfaces of the panels (2) or (3) that constitute the body of the article of office (1) for the preservation of documents, either this is a portfolio, with rings or hoops, of fastenings or similar, by virtue of that the mentioned fastening element does not interfere with the normal operation of any of the articles to which it could be added.
