The folder body of 1-configuration file folder, the board of 2-main body, 3-as the rubber components of elastomeric element, the loam cake of 7-configuration file folder, F-file, P-paper class (magazine, books, CD-ROM, DVD etc.).

The specific embodiment

According to Fig. 1-Fig. 8 the embodiment that the present invention specializes later file is described below.Fig. 1 is the front view of the folder body 1 of configuration file folder, and Fig. 2 is the rearview of folder body 1.As shown in Figure 1, folder body 1 by ground paper make as the board 2 of main body and formed as the rubber components 3 of elastomeric element parts.

Board 2 is also bigger than the specification of A4, B5 paper class, is rectangle slightly.The middle body of board top 2e one side has three hole 2g that the interval is identical.These holes 2g has been cut into circle.

Banded rubber components 3 is made similar annular.As shown in Figure 2, rubber components 3 is fixed on the board 2 by 4 points (referring to fixing point P1-P4) of board 2 back side 2b.Specifically, rubber components 3 2b is overleaf lacked near the centre of direction (the Y direction among Fig. 2), the P1 of bearing, P2 in the right of board 2 2c one side (being the left side among Fig. 2) and left side 2d (being the right side among a Fig. 2) side utilize first metal parts 4 that slightly is the U font to come fastening.

Rubber components 3 is the side of the following 2f of 2b overleaf, and the P3 of bearing, the P4 of symmetry that clips the centre position of following 2f comes fastening with second metal parts 5 that is the U font slightly.Specifically, with the length of board 2 length directions (being directions X among Fig. 2) relatively, second metal parts 5 is fixed on From Left 2c and the right 2d about 3/8 position far away respectively.Its result shown in solid line among Fig. 2 and two point dotted line, is provided with fixing point P1-P4 on the 2b of the back side of board 2, the rubber components 3 in the position of these points with first metal parts 4 and second metal parts 5 fastening forms a trapezoidal shape.

And, among being fixed on rubber components 3 on the board 2 by first metal parts 4 and second metal parts 5, make from first metal parts 4 and strain takes place, from the positive 2a one side configuration of back side 2b one side direction to the sloping portion 3a (the two point dotted line Fig. 2) that second metal parts 5 extends.Its result, as shown in Figure 1, each rake 3a is configured to extend to following 2f respectively from the right 2c of board 2 and left side 2d, and passes the bight, bottom right and the bight, lower-left of board 2 sideling.

If be configured in the external force that the rake 3a of positive 2a one side is subjected to breaking away from board 2 positive 2a, will produce elastic force near positive 2a.Because shown in the two point dotted line of Fig. 1, if each angle as the paper class P of paper class is clipped between rake 3a and the board 2, paper class P will be tilted the 3a of portion and be fixed on the board 2.And, between rake 3a and board 2, such as the words of pressing from both sides tens of paper class P, even need the thickness of the object of arrangement to become big, but because elastic force to board 2 be given and be given as security to rubber components 3 can to paper class P etc., so paper class P etc. can be fixed, and can not split away off from board 2 theres.That is to say that strain takes place the thickness of the paper class that rubber components 3 can be put in order as required.

Because board 2 is bigger than paper class specification, so as shown in Figure 1, also also have not by what paper class P covered and write region R even folder is gone up paper class P, this writes the region R the inside can write literal etc. with pencil etc., has the function on title bar and account hurdle.

As shown in Figure 2, if the line part 3b that is arranged on the rubber components 3 between first metal parts 4 from top 2e one sideway swivel of board 2 and move to the side of positive 2a, just as Fig. 3 was represented, straight line portion 3b will be in the side of positive 2a.And line part 3b passes positive 2a at the length direction (being directions X among Fig. 3) of board 2.Therefore, the paper class P that is fixed the one angle by rake 3a also by straight line portion 3b support fixation, so just is in to prevent that more reliably it is from board 2 fallen states.

Like this, between board 2 and rubber components 3, clip the folder body 1 of paper class P etc., because its very thin thickness and very smooth, so can be a lot of folder body 1 flat top uses that pile up desk etc.In addition, because folder body 1 is bigger than the specification of paper class, so just can press from both sides into the files of all sizes such as other file that clip paper such as the A4 version, envelope, magazine, file together.

Below, will the moving also loam cake 7 of configuration file folder that uses with described folder body 1 association be described according to Fig. 4 and Fig. 5.Fig. 4 is the front view of loam cake 7, and Fig. 5 is the rearview of loam cake 7.

In Fig. 4 and Fig. 5, loam cake 7 is that ground paper is made, and is made up of board 8 and handle portion 9.Board 8 is made oblong-shaped slightly.And the length of the shorter direction of board 8 (the Y direction among Fig. 4) also will be lacked than the length (the Y direction among Fig. 1) of the shorter direction of the board 2 of folder body 1.

Handle portion 9 is made of one with board 8.Shown in the two point dotted line among Fig. 5, handle portion 9 is also overlaped three cut footing 9a when loam cake 7 is excised from ground paper, is close to trapezoidal shape thereby formed one.So handle portion 9 by two ground paper overlapping form be not easy breakage.Also have, as shown in Figure 4, the mid portion of handle 9 is formed with the hole 9b of ovalize slightly, and the size of this hole 9b is the degree that a plurality of fingers can pass through.

Be formed with notch 10 respectively at the right of board 8 8e and left side 8f.Notch 10 is by the 10a of fastening portion of circular arc and form skewed tapered portion 10b from the bottom of the 10a of fastening portion of this circular arc to top 8c and formed.

Also have,, be formed with embedding

mouth

12a, 12b and fastening hole 13a, the 13b of symmetrical circular arc in two places of board 8 following 8d one sides.The embedding mouth 12a on right side makes from the following 8d of board 8 and forms circular arc to oblique upper right side.In addition, the fastening hole 13a on right side is cut into roughly oval shape, to the right 8e lopsidedness.And on the other hand, the embedding mouth 12b in left side makes and forms circular-arc from the following 8d of board 8 to oblique upper left side.And the fastening hole 13b in left side is cut into roughly oval shape, to left side 8f lopsidedness.Interval D 1 between the otch of the following 8d of pair of right and left embedding

mouth

12a, 12b is configured in the positive 2a of folder body 1, and it is bigger than the interval D 2 (with reference to Fig. 1) between the following 2f of the 3a of pair of angled portion in the lower left corner of passing board 2 respectively sideling and the lower right corner.

In board 8, be provided with the 1st folding line 14 and second folding line 15.First folding line 14 is made near the central authorities of board 8 parallel than length direction (directions X among Fig. 4) with board 8.This folding line 14 designs to such an extent that be easy to fold into positive 8a one side from board 8.

Second folding line 15 is set to than first folding line 14 also close following 8d, and makes identical with the shape of first folding line 14.Therefore, board 8 is easy to fold into from first folding line 14 and second folding line 15 these two position the side of positive 8a.

As shown in Figure 6, loam cake 7 is fixed on the folder body 1 and can very freely loads and unloads, in more detail, at the positive 2a of the board 2 of fixing paper class P and be configured in two angles of inserting loam cake 7 following 8d one sides between the rake 3a of the rubber components 3 on the positive 2a.And the sloping portion 3a of rubber components 3 is inserted in respectively among embedding mouth 12a, the 12b of loam cake 7, and not tight with fastening hole 13a and 13b.So, as shown in Figure 6, apply elastic force for rubber components 3, loam cake 7 will be fixed on the main body 1 of file.

And the interval D 2 of the following 2f part of 1 to two rake 3a of interval D between the otch of embedding this

moment mouth

12a, 12b is also big.Therefore, when between the main body 1 of rake 3a that two angles of loam cake 7 is inserted rubber components 3 and file the time, the porch of embedding mouth 12a, the 12b of loam cake 7 just is equivalent to the rake 3a of the main body 1 of file, is directed to fastening

hole

13a, 13b so rake 3a just can waltz through embedding

mouth

12a, 12b very much.And, because embedding

mouth

12a, 12b form circular arc from the inboard to the outside, so rake 3a just can utilize the elastic force of rubber components 3 to be directed to fastening

hole

13a, 13b very naturally.Also have, fastening

hole

13a, 13b make tilting with the roughly the same angle of rake 3a, so just can not to the situation of the useless tension force of rake 3a under sloping portion 3a tightly very simply.

In addition, the embedding mouth 12a on right side makes to the shape of oblique upper right side formation circular arc, the embedding mouth 12b in left side and makes the shape that forms circular arc to oblique upper left side.So, when loam cake 7 from the rake 3a of rubber components 3 when the state of

tight fastening hole

13a, 13b rises upward, circular-

arc embedding mouth

12a, 12b will play the effect of tight sloping portion 3a, so loam cake 7 is not easy to detach the main body 1 of file.

Like this, the main body 1 of file and loam cake 7 have just constituted file F.Paper class P is clipped between folder body 1 and the loam cake 7, and the angle by supporting downside by the rake 3a of rubber components 3 just can keep stable status.At this moment, even loam cake 7 is arranged on the folder body, also can directly see the region R that writes of folder body 1 from the outside.And in state shown in Figure 6, board 8 positive 8a one sides the line part 3b of the rubber components 3 of board 2 back side 2b one side that is configured in folder body 1 is configured to loam cake 7 so just can firmly fix the paper class more.

When moving file F, finger is put between the hole 2g of main body 1 of the hole 9b of handle portion 9 of loam cake 7 and file and just can have moved.At this time, because reinforce handle portion 9, so even repeatedly with finger insertion hole 9b, handle portion 9 can be not damaged yet with footing 9a.In addition, any one that can also insert finger among the hole 2g of main body 1 of the hole 9b of loam cake 7 or file moved file.

When the represented state of Fig. 6, if the line part 3b of the rubber components 3 of the back side 2b that is configured in folder body 1 etc. is rotated from the top 2e direction of folder body 1, just as Fig. 7 is represented, just can be arranged to cross loam cake 7 positive 8a to straight line portion 3b and uses.The stable state that just can keep the paper class when using so better.In addition, while the paper class P that when helping paper class P etc. to come in and go out smoothly, can also read select.

In addition, the line part 3b that is configured in positive 8a one side is not tightened on the handle portion 9, perhaps the part of line part 3b is configured on the side of loam cake 7 back side 8b and can uses.Just shown in the two point dotted line among Fig. 7, a part of tilted configuration of the line part 3b of rubber components 3.Also have, as the solid line of Fig. 7 is represented, is not to allow straight line portion 3b cross the whole positive 8a of loam cake 7, but shown in the two point dotted line among Fig. 6, straight line portion 3b is not only tightly used on handle portion 9.

In addition, in affirmation or in referring to the paper class P that is clipped among the file F, as shown in Figure 8, in the position of first folding line 14 board 8 of loam cake 7 is translated into positive 8a one side, so just can see the paper class P between the board 2 that is clipped in loam cake 7 and folder body 1.

The board 8 of loam cake 7 is turned up towards the side of positive 8a at second folding line 15 place, then back side 2b one side of also will part up than first folding line 14 of board 8 translating into the board 2 of folder body 1, will be as Fig. 9 be represented, just can be referring to whole paper class P.And, catch the words of the folded part of the loam cake 7 among Fig. 9 and folder body 1 just can fix the end of paper class P with hand, thereby while the paper class P that can leaf through referring to every page file.At this moment, 3 pairs of loam cakes of rubber components 7 are given with to the approaching elastic force of folder body 1 time, by in second folding line, the 15 crooked bounces that produce the board 8 from second folding line 15 to following 8d one side.Rely on this bounce, paper class P just is fixed between loam cake 7 and the folder body 1, can play the effect of clip.Also have, rubber components 3 is stapled on the fixed part 10a of loam cake, thereby can not fall down from loam cake 7 and folder body 1.In addition, if the loam cake 7 turned up is put back into folder body 1 one sides, rubber components 3 will utilize the effect of the elastic force of shrinkage direction, leads back to original position (position shown in Fig. 6) by the tapered portion 10b of otch 10.
