Therefore the present invention in view of the above problems, be not limited to above-mentioned file with ring-type bookbinding folder, same in file with various bookbinding folders, a kind of artificial operation that do not apply is provided, open and close that cover part and bookbinding press from both sides engage or its releasing is not carried out, disposable good file is a main purpose.

File of the present invention is to have: the switching cover part at a pair of folder face folder end, be located at the bark pocket back between these cardinal extremities that open and close cover part and be located at the bark pocket back and even the file of the bookbinding folder of the quilt bookbinding bodies such as bound document of the inner face side of switching cover part, it is characterized in that, its the 1st formation, on the closed position that at least one side's the relative bark pocket of switching cover part back is closed, opening and closing cover part formation grooving from pressing from both sides corresponding zone to not pressing from both sides corresponding zone with bookbinding with bookbinding, on the position that surrounds by the above-mentioned grooving that opens and closes cover part, form the fastener that closes with above-mentioned bookbinding mounting board simultaneously, on the outside left of the grooving that opens and closes cover part, set with bookbinding and clip the butt zone that connects and limit the engaging that engages the unit that constitutes by above-mentioned fastener and bookbinding folder.At this, as the closed position that opens and closes cover part, two sides' switching cover part is in the position on opposite mutually at the cardinal extremity warpage, perhaps has only a side switching cover part to be in this position.

If this formation, when accident has carried out closing the action that opens and closes bark pocket, the grooving outside be fastener around, connect because of the butt zone that opens and closes cover part is clipped with bookbinding, can prevent automatically with fastener with bind mounting board and close and become blocked state.Therefore, in that fastener and bookbinding mounting board are closed, must operate wittingly, or conversely fastener can not be disengaged if do not operate wittingly just with the fastening state of binding folder.

Apply this operating physical force of having a mind to relative effectively to fastener, as clamping close device preferably by only pushing from the outside that opens and closes cover part near fastener or its, the formation that this fastener just closes with the bookbinding mounting board.By this formation, because if do not push near the fastener that opens and closes the position of closing with the bookbinding mounting board in the cover part or its by artificial operation, therefore just can not make fastener and bookbinding mounting board close, can eliminate by mistake inconvenience effectively the file clamping.And, if after fastener and bookbinding mounting board were closed, because if do not apply artificial operating physical force on the rightabout that engages direction with this, this engaging just can not removed, and can eliminate the inconvenience of by mistake file being opened simultaneously.

In the simple formation as this fastener, can enumerate by what above-mentioned grooving surrounded and end tongue piece for tongue-shaped card.Close with the bookbinding mounting board for making this card end tongue piece, this card is ended tongue piece push to good to the thickness direction that opens and closes cover part.For ending position beyond the tongue piece by pushing the card that opens and closes cover part, difficult to produce the aspect that engages that card ends tongue piece and bookbinding folder, preference card ends tongue piece and only engage the regional butt of other parts that bookbinding is pressed from both sides and butt with the part of bookbinding folder.Specifically, make width dimensions that card ends tongue piece end tongue piece and should be suitable to the size of the finger tripe of the thickness direction pressing operation of switching cover part is relative with will blocking.

As ending the bookbinding folder that tongue piece engages with this card, enumerated possess the substrate of being located at bark pocket back inner face side, on this substrate both side ends and the inner face of the switching cover part at the folder face folder end of above-mentioned closed position in the face of the so-called tubular type bookbinding folder of set a pair of stitching plate in position and the bookbinding pipe that runs through bound document etc. that between this stitching plate, is provided with, it is good making card end that tongue piece engages with stitching plate subtend face each other at closed position.At this moment, card ends the width dimensions of the fastener branch that engage with stitching plate on the tongue piece, and is preferably little than the stitching plate longitudinally size along the longitudinally at bark pocket back.

In addition, end during bookbinding that tongue piece engages presss from both sides as preferred and card, enumerate be located at the bark pocket back or wherein a side open and close the bookbinding important document of a plurality of ring-types that can open and close of the inner face side of cover part, at this moment, closed position make that card ends that tongue piece and ring-type bind important document interior good to constituting of engaging of face side.At this moment, blocking the width dimensions that ends the fastener branch that engages with the bookbinding important document on the tongue piece, the maximum open width dimensions when caing be compared to the bookbinding of binding in the important document most is little.

The 2nd basic comprising of file of the present invention, it is characterized in that, opening and closing on the cover part, on the closed position of the relative bark pocket of the switching cover part back apolipsis that makes at least one side, form the fastener that is provided with and card claw stop that optionally with bookbinding mounting board close outstanding to the portion's inner face side that opens and closes bark pocket; Pass through strain in the base end part formation of fastener simultaneously, make this card claw stop be positioned at the exterior side faced with the switching cover part of bookbinding folder and at the non-clamped position that does not engage with the bookbinding folder, until the hinge folding part of moving with the interior clamped position that engage to the face side of bookbinding folder at above-mentioned card claw stop; By side direction fastener externally applied forces from the outside, move for making this fastener slide to the retreating position that the card claw stop is kept out of the way to anti-bookbinding folder one side from above-mentioned non-clamped position, make this elongation of hinge folding part or contractive action by strain, and by side direction fastener externally applied forces from the outside, for making the card claw stop rotate to the interior implantation site of slipping into to the face side that do not have to the bookbinding folder from above-mentioned retreating position, should cut with scissors the folding part as the rotational action device by strain, by elongation or the contractive action and the rotational action of this hinge folding part, constitute the clamping close device that fastener and bookbinding mounting board are closed.

Under the situation of this formation, owing to make card claw stop and bookbinding mounting board close, minimumly must carry out the operation in following 3 stages, at first the effect by external force makes the elongation of hinge folding part or shrinks, and fastener is slided from non-clamped position move to retreating position; Then the effect by external force is rotated the hinge folding part, fastener is turned to from retreating position do not have the implantation site; The hinge folding part is shunk or elongation, make fastener never move to clamped position in the implantation site, do not press from both sides the inconvenience of carrying out snap lock or the opposite state that unlocks by unexpected external force naturally with bookbinding so can not produce fastener.Therefore, same with the file of the 1st basic comprising, can constitute and will operate the good file of usability that the fastener that opens and closes cover part is closed with the bookbinding mounting board and realize closure earlier wittingly.

Even in the file that constitutes like this, for making above-mentioned effect effective, as clamping close device preferably by only pushing fastener from opening and closing the cover part outside, the formation that above-mentioned card claw stop side and bookbinding mounting board close.

And this moment is smooth and easy for the action of fastener, can open and close around the fastener of cover part, forms an open side that is provided with card claw stop and the closed slit that cuts with scissors folding part one side.Have again, in this slit, fastener is connected with the switching cover part, and mooring can make the allocation position opening and closing on the cover part of fastener stablize in the auxiliary brace of non-clamped position as if being formed on position in addition, hinge folding part.Therefore, do not apply the operating physical force of the degree of the power that surpasses the auxiliary brace that is used for the mooring fastener, just can not make the fastener action, can more effectively prevent fastener and the locking unintentionally of bookbinding folder or situation about unlocking.Also having, is to improve in this case the easiness and the accuracy of fastener operation, preferably forms on fastener from the exterior side that the opens and closes cover part recess to the inner face side depression, and the slit by this recess forms the card claw stop on by open leading section.

Have again, same with the file of the 1st basic comprising even in the file that constitutes like this as the bookbinding folder that is fit to, can enumerate tubular type bookbinding folder or ring-type bookbinding folder.

The 3rd basic comprising of the file that the present invention is correlated with is characterized in that, is opening and closing on the cover part, on the closed position of closing at the relative bark pocket of the switching cover part back that makes at least one side, forms with bookbinding and presss from both sides the fastener that optionally engages; Form by making this fastener simultaneously to hinge folding part that the thickness direction strain that opens and closes cover part is rotated at the base end side of fastener; For the elastic force that fastener is rested on bookbinding folder and the hinge folding part exterior side that opens and closes the cover part opposite is set at, littler than relative fastener by the power that the bookbinding folder can act on from opening and closing cover part inner face side butt, constitute side from the outside and be added to external force on the fastener when surpassing the elastic force of hinge folding part, make the clamping close device that this fastener and bookbinding mounting board close.

According to this formation, when having closed the switching cover part with big external force, the hinge folding part is if bear the power that switching cover part contact bookbinding folder bears, because fastener is kept out of the way to the outside of switching cover part, open and close cover part contact bookbinding and press from both sides and flick, fastener can not engage with the bookbinding folder.Therefore, same with the file of the 1st and the 2nd basic comprising, can accident will not open and close cover part with the locking of bookbinding folder, can constitute the good file of usability.

In this case, the operation that will have a mind to formerly just can make the fastener that opens and closes cover part close and realize closing and close with the bookbinding mounting board, clamping close device is preferably by only pushing from the outside that opens and closes cover part near fastener or its, the formation that this fastener just closes with the bookbinding mounting board.

And, around the fastener that opens and closes cover part,, can make the action of fastener smooth and easy because of forming the open slit that is provided with the closed hinge of fastener one side folding part one side.In this case, for example constitute the hinge folding part of tongue-shaped fastener and this fastener base end side by the formation of slit, do not have a mind to form hinge folding part, the notion that zone with hinge function that forms or position also comprise the described hinge of this basic comprising folding part even be not when forming other constitutive requirements.Have, even for other basic comprising, same situation also can be set up again.And, slit is interior to make the position of fastener beyond the hinge folding part be connected with the switching cover part if form, and the fastener in above-mentioned closed position presss from both sides the auxiliary brace of mooring on the position that does not engage with bookbinding, then can improve the stability of fastener equally with the 2nd basic comprising.

Especially, as forming on the fastener to opening and closing the outstanding projection of cover part inner face side, this projection constitutes with the exterior side butt of bookbinding folder, can hinder unexpected that fastener and bookbinding press from both sides by jut and engaging.And, under the situation that the hinge folding part forms at the base end side that more is in the switching cover part than fastener, because the card claw stop that engages with the inner face side of bookbinding folder is set on the projected front ends, can be so that fastener and bookbinding be pressed from both sides positively locked.Even as preferred bookbinding folder in this basic comprising, it also is self-evident enumerating tubular type bookbinding folder and annular binding clip.

Have again, have only earlier push fastener or its from the outside that opens and closes cover part near, and fastener with the 4th basic comprising that the bookbinding folder just can engage is, on the bookbinding folder, be arranged on the closed position upper edge and open and close the outstanding jut of cover part inner face, open and close and then form the slit that optionally engages and constitute fastener with the jut of bookbinding folder on the cover part, this structure also can reach the purpose same with the file of above-mentioned each basic comprising.

In addition, the operation that as nobody is, opening and closing cover part and bookbinding press from both sides engage or remove with regard to the clamping close device that can not carry out has in the 5th basic comprising of the present invention of useful structure, enumerated the file of following formation: make position that the part of bookbinding folder is exposed or near the slit it in opening and closing to be formed on the cover part to extend on the closed position, and as fastener, in this slit, be guided along the outside or inner face is pressed mobilely by external force, and optionally be located at the slide block that opens and closes the above-mentioned fastener of formation on the cover part with the bookbinding mounting board closes.
