The specific embodiment

Below, with reference to description of drawings embodiment of the present invention.

First embodiment

Fig. 1 shows the approximate three-dimensional map of the file open mode of first embodiment, and Fig. 2 shows the approximate three-dimensional map of the stitching plate parts being with the state that takes off from bookbinding.In these figure, file 10 is made of bark pocket body 11 and the bookbinding folder 12 that is installed on this bark pocket body 11.Bark pocket body 11 by folder face 13, via clip back 14 with at the bottom of the folder that this folder face 13 is connected 15 and from the inside side of clip back 14, promptly this clip back 14 and the interface at the folder end 15 divide the installation portion 16 of the sheet that beginning forms with the state invagination that forms two layers of thickness to the inside to form.As shown in Figure 2, on two zones of the above-below direction of installation portion 16, be formed into right inboard aperture 17,17 respectively, and paired apertura lateralis 18,18, utilizing these inboard aperture 17 and apertura lateralis 18, bookbinding folder 12 is able to respect to bark pocket body 11 disassembled and assembled freelies.

Above-mentioned bookbinding folder 12, by the bookbinding of the bookbinding hole P1 that can be inserted into file P with 20 be combined in this bookbinding and form with the stitching plate parts 21 on 20.Bookbinding is made of the paper tape that is roughly flat band shape on the whole with 20.Specifically, as Fig. 4 and shown in Figure 6, be arranged to paper yarn or the mutual almost parallel of spill 20A ground are disposed the marble paper rope shape that is formed by connecting.The radical of paper yarn or spill 20A, there is not specific restriction, in the present embodiment, adopted by interconnecting four paper tapes that form and constituted, on width, possessed the bookbinding band of thinner wall section 20B of the thickness attenuation relatively of the coupling position that three its shape of cross sections of place are arranged, thus, bookbinding is with 20 can be that deformed part carries out bending (with reference to figure 6) with thinner wall section 20B.

Be with 20 for above-mentioned bookbinding, the length that is set to spill 20A is about 210mm, diameter be about 1mm strong about, and will form to bind and be controlled in the size about 5mm with 20 o'clock width.But these sizes or size are not to set in order to limit the present invention, can change as required yet.As everyone knows, spill 20A is owing to be to cut out to such an extent that very thin spill becomes band and forms, so one intensity is just very strong.Therefore, their being connected many and intensity when forming banded marble paper rope shape just further strengthens, can stand continuous repeatedly uses such as bending, it is very big and can not produce the bookbinding band of change in size basically to have formed so-called hardness simultaneously.By the way, common press strip file generally is that waste treatment of just carrying out file after general about 3000 times etc. is operated in the dismounting of the stitching plate parts when carrying out the additions and deletions of file.Like this, suppose to carry out every day 5 dismounting operations, remove in 1 year when working day after holiday of office being about 240 days, in 1 year, will carry out 1200 times dismounting operation, carry out 2400 times dismounting operation in 2 years.When the bookbinding folder that uses the present embodiment carries out the dismounting operation, even 2400 times dismounting operation also still remains on the level that does not harm use, so can not cause making shorten the service life of file because of the hypofunction of binding band.In addition, bookbinding is with 20, as shown in Figure 3, the zone, intermediate portion is positioned at the upper face side of installation portion 16, and be held from above-mentioned inboard aperture 17,17 walk around the folder ends 15 1 side, the both end sides zone of having passed apertura lateralis 18,18 again is from the outstanding to the inside state in the surface of installation portion 16.

Above-mentioned stitching plate parts 21 for example, with made of paper or be that moulding material constitutes with synthetic resin etc., to shown in Figure 7, are set to the lengthy motion picture shape as Fig. 4 on the whole.In more detail, stitching plate parts 21 possess longitudinally along above-mentioned installation portion 16, are the substrate 25 of the above-below direction configuration of bark pocket body 11, the pair of

sidewalls

26,26 of short dimensional directions both sides that is arranged on this substrate 25 and the groove 27 that is formed by aforesaid substrate 25 and sidewall 26,26.In addition, stitching plate parts 21 are being set as under the situation made of paper, for example, as specially permit in No. 2951933 bulletin disclosed like that, can and be shaped into shape by the moisture additive of interpolation in the mixture of paper fiber and starch and obtain.Stitching plate parts by such method for making obtains have very hard constancy, can guarantee not to be inferior to the durability of above-mentioned bookbinding tape lifetime.

Aforesaid substrate 25 has formed the

square insertion path

28,28 that can pass with 20 both end sides for the bookbinding of coming out from these substrate 25 projections.Insertion path 28 in the present embodiment forms by being roughly square hole, but also can form notch to the inside by width one distolateral sidewall 26 parts from substrate 25.Like this, need not just bookbinding can be positioned in the notch with 20 sides from stitching plate parts 21 with bookbinding with 20 side direction upper face side insertions below substrate 25.Here, become bookbinding in each zone of inserting

path

28,28 and approaching the groove 27 between longitudinally end 25A, the 25A of these substrates 25 that insert

paths

28,28 most with 20 holding tank 27A, 27A.Here, with the width of groove 27 and holding tank 27A, be set to identical or bigger slightly with the width of binding than it with 20, thus, bookbinding with 20 states that are embedded in the holding tank 27A under, can not produce excessive binding force with 20 width inward at both ends side from this bookbinding.

In the groove bottom 27B of the holding tank 27 that forms above-mentioned bookbinding band, base portion side at sidewall 26,26 forms the slit 32,32 that extends along above-mentioned longitudinally, by this slit 32, be with 20 to embed holding tank 27A or remove when embedding will binding, can make groove width dimensions, be that size between the sidewall 26,26 enlarges, perhaps make sidewall 26,26 be returned to the home position.In addition, in holding tank 27A, as shown in Figure 7, groove bottom 27B be formed pars intermedia for the highest, about roughly the symmetry mild curved surface.That is, be formed from above-mentioned insertion path 28 central portions and uprise gradually, reduce gradually to substrate end 25A from central portion simultaneously to groove bottom 27B.In addition, form the sidewall 26 of above-mentioned holding tank 27A, its top forms pars intermedia with the curvature with groove bottom 27B same degree higherly, simultaneously as Fig. 5 and shown in Figure 6, is formed with the projecting strip part 34,34 as baffle element respectively on the opposite face on the top of sidewall 26,26.Gap size between these projecting strip parts 34,34, be set as littler than bookbinding with 20 wide size, a side in the path of above-mentioned insertion simultaneously 28 and a side opposite with it be formed broad, and, the pars intermedia zone becomes minimum, sees and roughly is similar to arciform shape thereby be configured to the plane.Therefore, the gap size between the projecting strip part 34,34, be set to the corresponding upper area in the pars intermedia of above-mentioned groove bottom 27B zone for the narrowest.At this, by the only about half of zone in the close above-mentioned insertion path 28 of above-mentioned groove bottom 27B, baffle element 34, constitute bookbinding with 20 the promotion portion that holds, by half remaining zone, form the bookbinding that is embedded among the holding tank 27A and remove promotion portion with 20 embedding.In addition, pars intermedia on groove bottom 27B forms a plurality of projections 37, by this projection 37, can guarantee that the bookbinding band 20A that avoids being contained among the holding tank 27A slides along surface direction.

Below, the effect of above-mentioned bookbinding folder 12 is described.

When bookbinding paper P, as shown in Figure 2, stitching plate parts 21 are bound relatively be with 20 to separate, make then from the outstanding to the inside bookbinding of installation portion 16 and be with 20 to erect.At this moment, though bookbinding is with 20 for made of paper, because use many spill 20A to constitute the samely, so can bring into play the strong state of so-called hardness with the gift rope.Therefore, the state after making bookbinding with 20 front zone during with finger tip, can making it keep this to erect towards the direction that erects.

Secondly, bookbinding is inserted the bookbinding hole P1 of file P with each front end of 20, insert simultaneously in the insertion path 28,28 on the stitching plate parts 21, stitching plate parts 21 are put down to the surface of installation portion 16, mounting goes up (with reference to Fig. 7) to paper P.After this, for example, the finger tripe of forefinger is against from inserting the outstanding bookbinding in path 28 with on 20 the base portion,, will binds and be with 20 to fill in the holding tank 27A so that this bookbinding with the such mode of 20 lodging, slips over the finger tripe.At this moment, the finger tripe is absorbed among the holding tank 27A, owing to be provided with the effect of slit 32, the size in the gap of projecting strip part 34,34 becomes big a little.In addition, be set to broad and groove bottom 27B from inserting the structure that path 28 1 sides begin to rise gradually owing to insert gap size between the projecting strip part 34,34 of path 28 1 sides, both interact, even near the bookbinding of the very difficult lodging the insertion path is with 20, also can carry out very smoothly for the bookbinding of accepting groove 27A with 20 initial hold operation.At this moment, bookbinding is with 20, as shown in Figure 6, in thinner wall section 20B location bending distortion, the width two ends cross projecting strip part 34 get into this projecting strip part 34 below, fasten with the following side of this projecting strip part 34.And, when finger tip is slided to transverse direction, be continuously applied pressing force, after surpassing the central portion zone of holding tank 27A, gap size between the projecting strip part 34,34 becomes greatly gradually, so later hold operation and can carry out (with reference to Fig. 7 (B)～(D)) more easily.Hold fully under the state that is embedded among the holding tank 27A will binding with 20, this bookbinding fastens with projecting strip part 34 with 20 postures that become approximate horizontal, and restriction upward perk or extract, in addition, go up projection 37 restrictions the moving that forms by groove bottom 27B along longitudinally.

In addition, when once more stitching plate parts 21 being taken off, as long as each end side that will bind with 20 with finger tip pinches, pull-up comes just passable upward.At this moment, owing to be in the gap size that the end of removing the projecting

strip part

34,34 that embeds a side has broad, so the resistance of removing is suppressed lessly, and bookbinding is with 20 flexural deformations on the position of thinner wall section 20B, both interact, and just can extract from 34,34 of projecting strip parts at an easy rate.

Therefore,, utilize bookbinding just can be embedded among the holding tank 27A, push bookbinding and press from both sides with the bookbinding of the simple type of the slide mass of 20 holding positions so can provide not need to be designed for 20 flexural deformation etc. by the first such embodiment.And,,, on the other hand, when waste treatment, also can not will bind and be with 20 from bark pocket body 11, to take off and direct discarding so can carry out regeneration to paper because bookbinding is made of paper with 20.In addition, if stitching plate parts 21 also are made of paper, then can with bookbinding with 20 and any one of stitching plate parts 21 take off, and directly regenerate or burn.And then bookbinding is with 20, also can utilize the yarn rope of market sale, can also reduce the production cost of bookbinding folder or file.
