CN2263582Y - Material saving multipurpose single breach folder - Google Patents

Abstract

The utility model provides a material saving multipurpose single breach folder, which is composed of two punch forming metal sheets, a spiral metal spring wire and a metal rivet. The utility model is characterized in that the front edge of one metal sheet forms a linear shape, and the front edge of the other metal sheet is punched with a square notch. Besides clamping paper, bills, etc., the material saving multipurpose single breach folder can also save metal material, and have new use functions. Particularly when various books or binding files and documents are read, the folder can be used for preventing turned pages from upwarping or turning automatically.

Description

How material-saving presss from both sides with the single port document

How the utility model material-saving relates to a kind of improved document folder with single port 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, and its leading edge is all linear) 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, and its leading edge is all linear, is plane-parallel article so can only be used to clamp upper and lower surfaces such as various paper, bill, and 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 single port 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: with the shape of two sheet metals of existing document folder and size is identical and its leading edge to be all linearity different, two sheet metals of the utility model document folder are designed to difformity shown in the drawings respectively.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 (mould that comprises punched metal sheet) 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 single port 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 single port document folder by drawing more, it is stepped that its front portion all becomes, respectively there is a herringbone reinforcement (1) at the middle part, handle (2) rear portion respectively dashes a circular hole (3), the handle both sides have all respectively and the rectangular otic placode of handle (4), and the otic placode afterbody all dashes an aperture, for the usefulness of dress metal rivet (5).The shape and size of two sheet metals are basic identical, and difference is that edge is a linear before the sheet metal, and there is a square breach (6) at the leading edge middle part of another sheet metal in then.Between the otic placode of above-mentioned two sheet metals, adorn a helical metal spring wire (7).Open after these spring wire two arms (8) 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 (5), make it riveted.For making this utility model material-saving how with the unlikely paper that scratches of the sheet metal of single port document folder, should strike out profile (9) 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 with the single port document, because sheet metal leading edge middle part dashes a square breach is arranged, so can save metal material.In addition, when reading the documentation that books and periodicals or binding bind into book form, how make the sheet metal that there is a square breach at its leading edge middle part and the top of the documentation of binding into book form facing to the books and periodicals that open or binding or the spine of bottom down with this material-saving with single port document folder, compressing upper and lower handle with finger opens two sheet metal front portions, make outstanding spine enter down the square breach of sheet metal front portion downwards, unclamp finger and can clamp the page of spine both sides, can protect the not perk and the upset automatically of page of opening.Perhaps make its down page of spine one side of the top of the square breach at the sheet metal leading edge middle part documentation of binding into book form facing to the books and periodicals that open or binding or bottom, make one section page of clamping the spine homonymy of two sheet metals, another section of two sheet metals then can be pushed down the page of spine opposite side, also 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 (5) and a helical metal spring wire (7) are formed presss from both sides with the single port document, helical metal spring wire (7) places between the otic placode (4) of handle (2) both sides of two sheet metals, helical metal spring wire two arms (8) 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 (5) is passed the last little punching of two sheet metal handle both sides otic placodes (4) and helical metal spring wire (7) makes it riveted, the leading edge that it is characterized in that a sheet metal is a linear, and another sheet metal leading edge middle part dashes a square breach (6).

2, how the material-saving by claim 1 regulation presss from both sides with the single port document, it is characterized in that all slick and sly shape profiles (9) of tool of two each corner of sheet metal leading edge.
