CN2281270Y - Multifunctional material-saving file for varied length documents - Google Patents

Abstract

The utility model provides a multifunctional material-saving file for varied length documents, which is composed of two metal sheets formed by punching, a spiral metal spring wire and a metal rivet. The utility model is characterized in that one metal sheet is somewhat longer, and the other metal sheet is somewhat shorter. The multifunctional material-saving file for varied length documents can be used for clamping paper, bills, etc., can save metal material, and has new use functions. Particularly when various books or binding documents are read, the file can prevent turned pages from automatically upwarping and turning.

Description

How material-saving presss from both sides with the length document

How the utility model material-saving relates to a kind of improved document folder with length document folder, be mainly used in the purposes that clamps various bills, paper except that having existing document folder, and can save raw material, particularly still can be used for clamping its upper and lower surface is not plane-parallel article.

The document folder system of all size of selling on the market is by two sheet metals (shape and size are identical) of drawing now, and a helical metal spring wire and a metal rivet assemble.The helical metal spring wire is contained between the handle both sides otic placode of two sheet metals, and its two arm opens after becoming 60 ° of angles approximately, withstands the handle end of two sheet metals respectively.The handle rear portion that compresses two sheet metals with finger is opened two sheet metal front portions, puts into the finger that paper, bill unclamp the pressing handle rear portion again, and two sheet metal front portions can clamp paper, the bill of putting into.Because the shape and size of two sheet metals of existing this document folder are identical, are plane-parallel article so can only be used to clamp upper and lower surfaces such as various paper, bill, its purposes is subjected to bigger restriction.

The purpose of this utility model provides a kind of improved document folder, is used to clamp the purposes of various paper, bill etc. except that keeping existing document folder, still can save raw material.Particularly can be used for clamping upper and lower surface is not plane-parallel article, for example, when reading the documentation that various books and periodicals and binding bind into book form, can press from both sides with the utility model document easily and prevent automatic perk of the page that opens and upset.

The purpose of this utility model be achieved in that the utility model material-saving how with length document folder still by the two sheet metals (thick 0.3mm ± stainless sheet steel of drawing, or flat cold-rolled sheet baking vanish or plating), a helical metal spring wire and a metal rivet assemble.But its substantive distinguishing features is: identical different with the shape and the size of two sheet metals of existing document folder, two sheet metals of the utility model document folder are designed to shape shown in the drawings.Its advantage is: except that still can be used for clamping upper and lower surfaces such as various bills, paper is the plane-parallel article, and still comparable existing document folder is saved raw material, reduces cost, and increases new function of use.When the example structure that will describe in detail below adopting, the equipment of producing existing document folder still can continue to use, and only need add and make a kind of mould, need not increase other production equipments and technological process.Now described in detail in conjunction with the accompanying drawings.

Fig. 1 and Fig. 2 are top view and the side views that the utility model material-saving is used the concrete structure of length document folder more.

With reference to Fig. 1 (top view) and Fig. 2 (side view), the utility model material-saving uses two sheet metals of length document folder by drawing more, a slice is grown (1) and another sheet is lacked (2), it is stepped that its front portion all becomes, respectively there is a herringbone reinforcement (3) at the middle part, and handle (4) rear portion respectively dashes a circular hole (5), and the handle both sides have all respectively and the rectangular otic placode of handle (6), the otic placode afterbody all dashes an aperture, for the usefulness of dress metal rivet (7).Between the otic placode of above-mentioned two sheet metals, adorn a helical metal spring wire (8).Open after these spring wire two arms (9) become 60 ° of angles approximately, its end is in the arc-shaped, withstands the circular distal (flange) of two sheet metal handles respectively, makes the leading edge driving fit of two sheet metals.Pass the little punching and the helical metal spring wire of two sheet metal handle both sides otic placodes with a metal rivet (7), make it riveted.For making this utility model material-saving how with the unlikely paper that scratches of the sheet metal of length document folder, should strike out profile (10) to the leading edge corner of two sheet metals with slyness, and rectangular shape.How this material-saving presss from both sides except that still can be used for clamping bill, the paper, because a sheet metal is shorter, so can save metal material with the length document.In addition, when reading the documentation that books and periodicals or binding bind into book form, how make its short sheet metal clamp the page of spine one side of documentation top that books and periodicals or binding bind into book form or bottom down with this material-saving with length document folder, one end of its long sheet metal can be pushed down the page of opposite side, can protect the not perk and the upset automatically of page of opening.

Claims (2)

1, a kind of two sheet metals by drawing, how the material-saving that a metal rivet (7) and a helical metal spring wire (8) are formed presss from both sides with the length document, helical metal spring wire (8) places between the otic placode (6) of handle (4) both sides of two sheet metals, helical metal spring wire two arms (9) open and its terminal circular distal (flange) of withstanding two sheet metals respectively in the arc-shaped after becoming 60 ° of angles approximately, metal rivet (7) is passed the last little punching of two sheet metal handle both sides otic placodes (6) and helical metal spring wire (8) makes it riveted, it is characterized in that a sheet metal is grown (1) and another sheet metal is lacked (2).

2, how the material-saving by claim 1 regulation presss from both sides with the twoport document, it is characterized in that all slick and sly shape profiles (10) of tool of two each corner of sheet metal leading edge.
