Abstract

A binder has a pair of first binding members and a pair of second binding members corresponding to the first binding members. When each of the fist binding members and corresponding each of the second binding members are relatively turned, tip portions of these first and second binding members are closed or opened, realizing a state where papers are bound or a state where papers are released from binding. The binder has opening means for applying a force in a direction where the tip portions of the first and second binding members are opened, and has an operation lever for relatively turning the first and second binding members against the opening means, and for retaining the tip portions at a closed position. The binder is characterized in that connection portions are provided in the tip portions The connection portions are connected to each other through temporary elastic deformation of at least either of the first binding members and the second binding members, and inhibit the opening operation of the tip portions by strengthening the connection by means of force applied by the opening means.

Description

Binder and file

Technical field

The present invention relates in office etc., can use well, possess action bars binder and file.

Background technology

For example, as this binder, as shown in figure 15, known have in such a way a binder that constitutes, promptly on base e, possess paired the 1st binding part a, a and with these the 1st binding parts a, a corresponding paired the 2nd binding part b, b, by the action that relatively rotates of corresponding the 1st binding part a and the 2nd binding part b respectively, utilize between leading section a1, the b1 to be closed or to open, realize bookbinding state or bookbinding disarm state for the paper class.In this binder A, possess: device for opening c, its direction of opening between leading section a1, the b1 of the 1st, the 2nd binding part a, b applies power; With action bars d, it overcomes this device for opening c, and makes the 1st, the 2nd binding part a, b relatively rotate action, thereby is maintained in its closed position between leading section a1, the b1 with them.

This binder, operate downwards by the action bars d between leading section a1, the b1 that will close the 1st, the 2nd binding part a, b, two binding part a, b overcome the power that is applied by device for opening c, thereby the direction between the a1 of closed front end portion, b1 relatively rotates action.Then, leading section a1, the b1 of the 1st, the 2nd binding part a, b dock each other, thereby close between them, under the confining force that is obtained by action bars d, have kept the bookbinding state by the paper class of the 1st, the 2nd binding part a, b realization.

On the other hand, when action bars d is operated upward, thereby when removing the confining force that is maintained in its closed position between leading section a1, the b1 with the 1st, the 2nd binding part a, b, on two binding part a, b, apply power on the direction of opening between leading section a1, the b1 by device for opening c, therefore two binding part a, b move relatively to the direction of opening leading section a1, b1, thereby carry out the transition to the bookbinding disarm state.

1st, leading section a1, the b1 of the 2nd binding part a, b shown in Figure 16 (a), have along the chimeric sleekly concaveconvex structure of switch direction and dock each other, and these binding parts a, b become the arch bridge shape in off position down.

; when dropping or other reason of binder A; make unexpected external force act on the 1st; the 2nd binding part a; when b is last; following situation is arranged; promptly because two binding part a; the leading section a1 of b; b1 just rotates sleekly and is docking together with concavo-convex along closing direction each other; even if therefore action bars d is positioned at the closed position; shown in this figure (b); thereby also easily to opening the direction strain at leading section a1; the gap temporarily appears between the b1; after the concavo-convex in addition disengagement; shown in this figure (c), under the state of dislocation, can not fully close again.Therefore, except the paper class is clipped between leading section a1, the b1, or outside the undesirable condition that comes off from binder A of paper class, also following undesirable condition can take place, promptly, even if want operating operation bar d, under the state of dislocation, cause obstacle for the binding part a of engagement, the opening operation of b, even if or can opening operation action bars d, binding part a, b plastic deformation when dislocation, thus diminish normal closing function.

Particularly, though 1st, the 2nd binding part a, b become the arch bridge shape in off position down, but in fact becoming bookbinding zone, is the standing portion of the 2nd binding part b that generally perpendicularly erects from base e, when the T of top portion only is reading, be used to zone that the paper class is passed through when adding reducing.And, the part of having only the T of this top portion, the particularly distance from the base end part a2 of binding part a to leading section a1 are bigger than needs, when external force acts on leading section a1, b1 side, be easy to produce strain, thereby exist above-mentioned undesirable condition to be inclined to more significantly.

In addition, when this binder A being installed in cover body B goes up and during configuration file folder F, as shown in figure 17, the shape of the T of top portion produces wasted space between gauge seal skin B1 and underseal skin B2, cause taking in the reduction of efficient, the increase of the unnecessary appearance and size of file F.

Summary of the invention

The present invention, being conceived to such problem is developed into, its main purpose is, be provided under the state that the 1st, the 2nd binding part is maintained in its closed position by action bars, even if unexpected external force acts on around the leading section, also can prevent clamping, coming off of paper class, and can guarantee the binder and the file of new structure of the normal closing function of action bars.

The present invention in order to reach this purpose, has used following device.

That is, binder of the present invention, it is following binder, promptly possesses the 1st paired binding part and 2nd binding part paired accordingly with these the 1st binding parts; And be constituted as by the action that relatively rotates of corresponding the 1st binding part and the 2nd binding part respectively and will close between the leading section or open, realize bookbinding state or bookbinding disarm state thus with respect to the paper class; And possess the device for opening that the direction of opening applies power between the leading section of the 1st, the 2nd binding part, and overcome this device for opening and make the 1st, the 2nd binding part relatively rotate action and the action bars that is maintained in its closed position between the leading section with them.And it is characterized in that, between above-mentioned leading section, be provided with the holding section, this holding section engages via the temporary transient strain of at least any one party of the 1st binding part or the 2nd binding part, and utilize the power that applies by above-mentioned device for opening to deepen this engaging, thereby forbid the opening action between the leading section.

When the direction operating operation bar between the leading section of closing the 1st, the 2nd binding part, two binding parts overcome the power that applied by device for opening and direction between closed front end portion relatively rotates action.Then, be located at the holding section between the leading section, via the temporary transient strain of the binding part of at least any one party and engage, under the confining force that obtains by action bars, can obtain the bookbinding state of the paper class of being undertaken by the 1st, the 2nd binding part.The holding section is the parts that utilize the power that applied by device for opening to deepen to engage, as long as temporarily strain is not applied on the binding part, engaging just can not removed.Therefore, even if owing to falling or other reason of binder, make unexpected external force act on the 1st, the 2nd binding part, and thus, 1st, between the leading section of the 2nd binding part to the direction strain of opening, also can prevent this deformed movement effectively, and the situation of closing again after the displacement etc.

On the other hand, when the operating operation bar, thus the confining force that is maintained in its closed position between the leading section of releasing with the 1st, the 2nd binding part, and then, during additional artificial temporary transient strain, the engaging of holding section is removed between the leading section of two binding parts.Owing to applied the power on the direction of opening between the leading section by device for opening on two binding parts, therefore two binding parts relatively rotate action to the direction of opening leading section, thereby can obtain binding disarm state.

According to the present invention, even if owing to falling or other reason, make unexpected external force be applied on the 1st, the 2nd binding part, also can forbid between the leading section of two binding parts to opening the direction strain, thus can eliminate effectively the clamping of paper class occur, come off, the situation of the malfunction of action bars etc.Thereby, with respect to fall, the neglectful collision of article etc., very solid, can improve reliability, durability effectively as binder.

The holding section is preferably by the 1st binding part to each other or the parts that engage to the mode of the mutually close temporary transient strain of direction to each other of the 2nd binding part.

Thus, to the strain of mutually close direction, can apply at an easy rate by the operation that pinches with finger tip etc.Thereby, can remove the bookbinding state of realizing by the 1st, the 2nd binding part simply with a hand.

Perhaps, the holding section is preferably by the 1st binding part to each other or the parts that engage to the mode of the temporary transient strain of direction that is separated from each other to each other of the 2nd binding part.Thus, to the strain of the direction that is separated from each other,, can apply at an easy rate by the operation of drawing back with two hands.Thereby, even if on the 1st, the 2nd binding part, applied higher rigidity, also can remove the bookbinding state simply with two hands.

As the concrete embodiment of holding section, can enumerate being made as by the inside crook on any one party that is located at the 1st binding part or the 2nd binding part and being located at the structure that the outside crook on the opposing party engages.

Like this, just can realize following holding section reliably by simple processing, it engages more sleekly in closing motion and deepens to engage with respect to the power of opening direction.

In addition, in order further to improve action effect of the present invention, preferably, the 1st binding part and the 2nd binding part, be base end part is installed on the base and makes the parts of its setting, on at least any one party of erectting the 1st distolateral binding part or the 2nd binding part, be provided with the top portion of extending in advance with base almost parallel ground in off position down.

Because the setting at least one side of the 1st binding part or the 2nd binding part is distolateral, be provided with the top portion of extending with base almost parallel ground, therefore compare with the binder that top portion is the arch bridge shape, even if actual bookbinding amount is identical, the distance from the base end part to the leading section is also less.Therefore, binding part becomes the parts that are difficult to strain, can further prevent situation about opening easily between the leading section effectively.

When above-mentioned binder being installed on the cover body and during the configuration file folder, in this document folder available action effect basically with above-mentioned binder is narrated identical.

Particularly, if be provided with the top portion of extending with base almost parallel ground, compare with the binder of arch bridge shape, the wasted space that produces between gauge seal skin and underseal skin is less, can avoid effectively taking in efficient reduction, cause the situation of increase of the unnecessary appearance and size of file.

The specific embodiment

(the 1st embodiment)

In Fig. 1, showed the major part approximate three-dimensional map of the file 2 that possesses binder 1, in Fig. 2～Fig. 5, showed the amplification front elevation of binder 1, enlarged left view, amplification plan view amplifies right view.File 2 possesses: cover body 3, and it has gauge seal skin 31 and the underseal skin 32 that links to each other via back of the body strip of paper used for sealing 33 in the centre; With binder 1, it is installed on the inner face of underseal skin 32.

Binder 1, on base 10, possesses the 1st paired binding

part

11,11, with 2nd binding

part

12,12 paired accordingly with these the 1st binding

parts

11,11, the action that relatively rotates by corresponding the 1st binding part 11 and the 2nd binding part 12 respectively, shown in Fig. 2 waits, become the structure that is closed or opens between leading section 11a, the 12a.In addition, this binder 1 possesses: device for opening 4, its direction of opening between leading section 11a, the 12a of the 1st, the 2nd binding

part

11,12 apply power (with reference to Fig. 4 etc.); With action bars 5, it overcomes this device for opening 4, and makes the 1st, the 2nd binding

part

11,12 relatively rotate action, thereby is maintained in its closed position between leading section 11a, the 12a with them.

If specifically describe, be exactly the 1st binding part 11 and the 2nd binding part 12, be the parts that become the closed loop of arch bridge shape in off position down.The 1st binding part 11 shown in Fig. 2 waits, constitutes to the crooked lentamente bending area 11y of the 2nd binding part 12 sides by the setting zone 11x that generally perpendicularly erects from base 10 with from this front of erectting regional 11x.In addition, the 2nd binding part 12, by in off position down, be erected to the setting zone 12x of the position higher slightly and constitute to the bending area 12y of above-mentioned the 1st binding part lateral bending song from this front of erectting regional 12x than above-mentioned setting zone 11x from base 10.By the closed position that leading

section

11a, 12a obtain, be positioned at from the T of top portion of arch bridge position to the 12 side displacements of the 2nd binding part.

Shown in Fig. 1 and Fig. 4 etc., link together by linking part 13 between base end part 11b, the 11b of the 1st paired binding

part

11,11, the rotation axial region 13a that constitutes the both end sides of this linking part 13 is installed in rotation on the bearing 10a that is located on the base 10.On the other hand, the 2nd paired binding

part

12,12 is fixedly mounted on base end part 12b on the base 10 respectively.And the 1st binding part 11 is that fulcrum ground rotates to rotate axial region 13a, thereby closes or open between leading section 11a, the 12a with the 1st binding part 11 and the 2nd binding part 12, realizes bookbinding state or bookbinding disarm state for the paper class.

Device for opening 4, shown in Fig. 4 waits, be following parts, promptly the part of the linking part 13 by making above-mentioned the 1st binding part 11 bends to crank-like, and from the position of rotating axial region 13a displacement, be provided with this and rotate the parallel bent axle 41 of axial region 13a, the while to be being fixed on cardinal extremity edge 42a side on the base 10, and makes front-end edge 42b side be provided with flat spring 42 from the mode that below and above-mentioned bent axle 41 bullets connect.And, constitute in such a way, promptly utilize the effect of flat spring 42, apply elastic force, this elastic force will be positioned at the closed position with and near the base end part 11b of the 1st binding part 11, push to opening direction via linking part 13.

Action bars 5 shown in Fig. 3 waits, by cursor 51, is erect and operative end 53 formations of the word of the falling L shape that is provided with to the continuous integratedly transfer part 52 of the direction of quadrature roughly with in the front of this transfer part 52 from this cursor 51.And, cardinal extremity with cursor 51, via the arm back shaft 51a parallel with the switch direction of the 1st, the 2nd binding

part

11,12, be installed in rotation on the support portion 10b that is erected to be located on the base 10, on the cross section of cursor 51 and transfer part 52, roller 54 is installed via roller back shaft 54a with base 10 almost parallels.On open position, like that, operative end 53 is positioned at the position of takeofing to oblique shown in dashed lines among Fig. 2 and Fig. 3, and roller 54 rollably contacts with position from the central displacement of the bent axle 41 of above-mentioned linking part 13.When from this push end 53, position, cursor 51 rotates along arm back shaft 51a, and roller 54 one sides are rolled on linking part 13, and one side moves to the central portion of linking part 13 gradually, and overcomes flat spring 42 and linking part 13 is pressed downwards.During this period, put aside elastic force on flat spring 42, the 1st binding part 11 one sides are rotated, leading section 11a one is close towards the leading section 12a of the 2nd binding part 12, close between final leading section 11a, the 12a.Promptly, the position that roller 54 dots from Fig. 3, a little by after descending most point, move solid line position among this figure that rises slightly, even if remove operating physical force, because therefore the bent axle 41 that is positioned at cursor 51 and linking part 13 state of quadrature roughly passes through elbow section action to operative end 53, the state that linking part 13 maintenances are pressed, binding

part

11,12 keeps closed conditions.Bearing by flat spring 42 of linking part 13 by exerting oneself.

When operation that action bars 5 is takeoff, roller 54 is on the linking part 13 that is pressed against on the flat spring 42, to moving with above-mentioned opposite direction, and after roller 54 has passed through to descend point most, the 1st binding part 11 one side is rotated in the opposite direction, leading section 11a should one side away from the leading section 12a of the 2nd binding part 12.But, in this embodiment, because therefore the existence of holding section 6 described later can only just not open between leading section 11a, the 12a.In Fig. 3,,, be provided with the stop mechanism that figure does not show, thereby action bars 5 is stopped on the position of takeofing of regulation at action bars 5 and base 10 or near it between portion when action bars 5 during from the status transition represented with solid line to the state that dots.

In such binder 1, present embodiment, between above-mentioned leading

section

11a, 12a, be provided with holding section 6, this holding section 6 engages via the temporary transient strain of the 1st binding part the 11, the 2nd binding part 12, and utilize the power that applies by above-mentioned device for opening 4 to deepen this engaging, thereby forbid the opening action between leading section 11a, the 12a.

This holding section 6, shown in Fig. 5 and Fig. 6 (a)～(c), by forming the outside crook 61 of the shape of the Outboard Sections excision of the leading section 11a of the 1st binding part 11 and forming inside crook 62 formations with the shape of the inside part excision of the leading section 12a of the 2nd binding part 12.Outwards crook 61 and inwardly crook 62, shown in Fig. 6 (b), (c) etc., near having chevron snap portions 61a, 62a on the position of front end, on its base end side position adjacent, have paddy shape snap portions 61b, 62b, between dig part 61ax, 62ax under forming.The paddy shape snap portions 62b (61b) of the chevron snap portions 61a (62a) of one side's crook 61 (62) and the opposing party's crook 62 (61), be in concavo-convex chimeric relation, chevron snap portions 61a, 62a each other, paddy shape snap portions 61b, 62b go up each other, pays identical shape.

When leading section 11a, the 12a of two

binding parts

11,12 from this figure (c) as this figure (b) near the time, the 1st binding

part

11,11 is each other to the mutual close temporary transient strain of direction, the 2nd binding

part

12,12 is each other to the temporary transient strain of the direction that is separated from each other, and engaging is simultaneously deepened in chevron snap portions 61a, the mutual friction of 62a one side phase simultaneously.Then, when chevron snap portions 61a (62a) falls into paddy shape snap portions 62b (61b), shown in this figure (a), form holding section 6, via this holding section 6, the 1 binding parts 11 and the 2nd binding part 12, on apparent, become the filament that constitutes 1 continuous closed loop.At this moment, the 1st binding part the 11, the 2nd binding part 12 returns to the preceding state of distortion from elastic deformation.

In addition, present embodiment is not to keep closed condition between leading section 11a, the 12a of the 1st binding part 11 and the 2nd binding part 12 by the shutoff device of pushing to closing direction, but by device for opening 4 that direction pushes keeps to opening.Its reason is: do not need excessive operating physical force and just can successfully carry out switching manipulation with lighter power, simultaneously when making the 1st binding part 11 and the 2nd binding part 12 be in closed condition, can not move tempestuously and produce noise, perhaps cause scaring, and then, owing to need not prepare parts in addition, therefore can also cut down the part number as device for opening.

On the gauge seal skin 31 of cover body 3, as shown in Figure 1, when closing, be provided with slit 31a on the corresponding position of formed arch bridge with above-mentioned the 1st, the 2nd binding

part

11,12, the T of top portion of arch bridge can be inserted in this slit 31a.In addition, be provided with the projection 31a1 that is fastened in the insertion position on interior week of arm on the opening edge of above-mentioned slit 31a.Be used for cover body 3 is maintained closing state.

As previously discussed, the binder 1 of present embodiment and the file 2 that it has been installed, when the direction of action bars 5 between the leading section 11a, the 12a that close the 1st, the 2nd binding

part

11,12 operated, two

binding parts

11,12 overcome the power that is applied by device for opening 4, and the direction between the 11a of closed front end portion, 12a relatively rotates action.Then, temporary transient strain via two

binding parts

11,12, be located at holding section 6 engagings between leading section 11a, the 12a, under the confining force of realizing by action bars 5, as representing with solid line among Fig. 1～Fig. 4, can obtain the bookbinding state of the paper class of being undertaken by the 1st, the 2nd binding

part

11,12.

Holding section 6, be the power of using the direction represented with arrow in Fig. 6 (a) by device for opening 4 to apply, deepen the parts of the engaging of chevron holding section 61a (62a) and paddy shape holding section 62b (61b), as long as the strain action that temporarily will not scheme to represent with arrow in (b) is applied on the 1st binding part 11 or the 2nd binding part 12, just can not engagement release.This is that following part 61ax, the 62ax of digging of the contact root of chevron holding section 61a, the 62a shown in Fig. 6 (a), (c) etc. has intermeshing relation each other because when will be when the axis of binding

part

11,12 is opened them.Therefore, even if owing to falling or other reason of binder 1, make unexpected external force act on the 1st, the 2nd binding

part

11,12, and thus, 1st, between leading section 11a, the 12a of the 2nd binding

part

11,12 to the direction strain of opening, also can prevent its deformed movement and dislocation effectively and the situation of closing again etc.For example, be that convenient file 2 is under situation about falling from the T of top portion side under the state that the gauge seal skin 31 and the underseal skin 32 of cover body 3 are opened, the T of top portion is subjected to reaction force from ground, perhaps inertia weight mainly acts on the 2nd binding part 12 from the paper class of bookbinding, and the outside external force that closed loop will be opened acts on the 1st binding part 11 and the 2nd binding part 12, owing to holding section 6 is the structures that engage with respect to the power of opening direction, so can keep closing state between leading section 11a, the 12a.Perhaps, even if at file 2 under the situation such as vertically fall of back of the body strip of paper used for sealing 33, inertia weight mainly acts on the 2nd binding part 12 from the paper class of bookbinding, particularly with respect to the 1st binding part 11 and the external force of vertical dislocation of the strip of paper used for sealing 33 of will supporting or opposing acts on the 2nd binding part 12, because on any one of 2 groups of closed loops that constitute by the 1st binding part 11 and the 2nd binding part 12, holding section 6 deeper engages because of this action, so can keep closing state between leading section 11a, the 12a.

On the other hand, as shown in Figure 7, when operating operation bar 5 as arrow among the figure, thereby remove the confining force that is maintained in its closed position between leading section 11a, the 12a with the 1st, the 2nd binding

part

11,12, in addition, as shown in Figure 8, when adding temporary transient strain artificially shown in arrow among the figure on the 1st binding

part

11,11, the engaging of holding section 6 is removed according to the order of Fig. 6 (a) → (b) → (c).Owing on two

binding parts

11,12, applied the power of the direction of between leading

section

11a, 12a, opening by device for opening 4, so two

binding parts

11,12, as shown in Figure 9, relatively rotate action to the direction of opening between leading section 11a, the 12a, thereby can obtain binding disarm state.

Like this, according to present embodiment, even if owing to falling or other reason, make unexpected external force be applied on the 1st, the 2nd binding

part

11,12, holding section 6 also can forbid between leading section 11a, the 12a of two binding

parts

11,12 to the situation of opening the direction strain, thereby can eliminate the clamping of paper class effectively, comes off, the generation of the malfunction of action bars 5 etc.Thereby, with respect to fall, the neglectful collision of article etc., very solid, can improve reliability, durability effectively as binder 1.

In addition, holding section 6 shown in Fig. 6 (b), is the parts that engage to the mode of the mutually close temporary transient strain of direction each other by the 1st binding

part

11,11, to the strain of mutually close direction, can apply at an easy rate by the operation that pinches with finger tip etc.Thereby, just can remove the bookbinding state that obtains by the 1st, the 2nd binding

part

11,12 simply with a hand.

Certainly, holding section 6, also be the parts that engage to the mode of the temporary transient strain of direction that is separated from each other each other by the 2nd binding

part

12,12, therefore to the strain of the direction that is separated from each other, by draw back the operation of the 2nd binding

part

12,12 with two hands, can apply at an easy rate.Thereby, even if on the 1st, the 2nd binding

part

11,12, applied under the situation of higher rigidity, also can remove the bookbinding state simply with two hands.

As concrete structure, holding section 6, be by the outside crook 61 that is located on the 1st binding part 11, the structure that engages with the inside crook 62 that is located on the 2nd engaging part 12, therefore just can realize holding section 6 reliably with simply processing to wait, it can carry out slick and sly snap action, deepen with respect to the power of opening direction to engage simultaneously when closing.

Configuration file pressed from both sides 2 o'clock this binder 1 being installed on the cover body 3, in this document folder 2 available action effect basically with above-mentioned binder 1 is narrated identical.

In addition, the holding section 6 of illustrated embodiment, though adopted following structure, outside crook 61 promptly is set on the leading section 11a of the 1st binding part 11, inside crook 62 is set on the leading section 12a of the 2nd binding part 12, by the 1st binding

part

11,11 each other to mutual close direction, other the 2nd binding

part

12,12 distinguish the mode of temporary transient strain each other to the direction that is separated from each other, the 1st binding part 11 and the 2nd binding part 12 are via

crook

61,62 and engage, but also can inside crook be set, outside crook be set in the leading section 12a of the 2nd binding part 12 side in the leading section 11a of the 1st binding part 11 side.

In addition, the holding section, so long as engage via temporary transient strain, and utilize the parts of deepening this engaging by the opening action applied force of device for opening 4, the direction of strain is not limited only to above-mentioned.

For example, holding section 6 α shown in Figure 10, constitute in such a way, upwards crook 61 α promptly are set on the leading section 11a of the 1st binding part 11, downward crook 62 α are set on the leading section 12a of the 2nd binding part 12, and slipping into the temporary transient strain of following mode of the leading section 12a of the 2nd binding part 12 with the leading section 11a of the 1st binding part 11, the 1st binding part 11 and the 2nd binding part 12 engage via crook 61 α, 62 α thus.

Such structure, even if for example file 2 falls from the T of top portion side, the outside external force that closed loop will be opened acts on the 1st binding part 11 and the 2nd binding part 12, owing to holding section 6 α are the structures that engage with respect to the power of opening direction, so can keep closing state between leading section 11a, the 12a.Particularly, if fall from the T of top portion side, come from the reaction force on ground, the paper class of bookbinding works as compression stress, thereby there be the situation of the 2nd binding part 12 to the direction plastic deformation of buckling, but snap-in structure according to illustrated above-below direction, because the 2nd binding part 12 slips into the situation of the below of the 1st binding part 11 and is under an embargo, therefore can suppress this plastic deformation effectively.In addition, even if plastic deformation also can be avoided situation about opening between the

binding part

11,12, thereby prevent the at random of paper class.Thereby, can realize file 2, it is with respect to acting on outside external force on the 1st binding part 11 and the 2nd binding part 12, that closed loop will be opened, and is more solid.

In addition, the binder of Figure 10, though have above-mentioned effect, but with respect to the 1st binding part 11 and the 2nd binding part 12 along back of the body strip of paper used for sealing 33 vertically and the external force of dislocation then is not very solid, but if Figure 11 such holding section 6 β, just can realize following file 2, it can be more solid with respect to acting on external force on the 1st binding part 11 and the 2nd binding part 12, that closed loop will be opened, and can overcome the external force that misplaces along the vertical of back of the body strip of paper used for sealing 33.

This holding section 6 β, be following parts, outside crook 61 β 1 and crook 61 β 2 that make progress promptly are set on the leading section 11a of the 1st binding part 11, inside crook 62 β 1 and downward crook 62 β 2 are set on the leading section 12a of the 2nd binding part 12, cause the 1st binding part 11 by while or priority, 11 each other to mutual close direction, other the 2nd binding

part

12,12 each other to the direction that is separated from each other, the action of temporary transient strain respectively, with the 1st binding part 11 relatively to the action of the temporary transient strain of direction of the below of slipping into the 2nd binding part 12, outside thus crook 61 β 1 and inside crook 62 β 1, upwards crook 61 β 2 and downward crook 62 β 2 hang over together, the 1st binding

part

11 and 12 engagings of the 2nd binding part.In this case, can realize that also the following of crook 61

β

1,62 β 2 digs part 61 β 1x, 62 β 2x each other, crook 61

β

2,62 β 2 following digs the state that part 61 β 2x, 62 β 2x mesh each other.

According to such structure, with respect to acting on external force on the 1st binding part 11 and the 2nd binding part 12, that closed loop will be opened, can not open between leading section 11a, the 12a yet, and can forbid the action that the 2nd binding part 12 slips into the below of the 1st binding part 11 because of compression stress, can also overcome along the external force of vertical dislocation of back of the body strip of paper used for sealing 33.Thereby even if from the T of top portion side file 2 is fallen, perhaps the file 2 that vertically makes along back of the body strip of paper used for sealing 33 falls, and also can keep the function of file 2 more reliably, prevents that the paper class from coming off.
