Description

Technical Field

[0001] This invention relates to a folder capable of holding paper. Background Technology

[0002] Previously, various folders with storage compartments for storing documents were known (for example, see Patent Document 1).

[0003] In this type of folder, by equipping the storage section, which is composed of the folder body, with sheet-like dividers, the space within the storage section can be divided into multiple sections.

[0004] As a countermeasure to reduce the number of parts while providing multiple dividers within the storage section, the following solution was studied: multiple dividers are formed by bending a sheet at the bending point.

[0005] However, when the aforementioned multiple dividers are arranged within the storage section, the portion closer to the open end than the bent portion must be fixed relative to the main body of the folder by means of welding or the like. Therefore, when storing documents in the storage section of such a folder, the portion with multiple dividers fixed relative to the main body becomes an obstacle, making it impossible to accommodate the documents inside.

[0008] Patent Document 1: Japanese Utility Model Registration No. 3210499 Summary of the Invention

[0009] The problem that the invention aims to solve

[0010] The present invention was made with regard to the above-mentioned situation, and its object is to provide a folder having a structure that can at least properly fix one piece, which has multiple dividers formed by bending at the bend, relative to the other pieces.

[0011] Methods for solving problems

[0012] That is, the present invention has the following structure.

[0013] The invention described in technical solution 1 is a folder with a storage section that uses dividers to divide space. Multiple dividers are provided in the storage section by bending a sheet at a bend. A sheet-like fixing piece is provided near the bend in the sheet. The fixing piece is disposed to either the left or right side relative to the middle part in the left-right direction of the divider. The fixing piece is fixed relative to the other sheets.

[0014] According to the folder described in technical solution 1, in the invention described in technical solution 2, the fixing piece is cut and erected from the vicinity of the bent portion in the piece.

[0015] According to the folder described in technical solution 1 or 2, in the invention described in technical solution 3, the fixing piece is configured to be able to be cut and erected by forming a roughly U-shaped slit in the piece.

[0016] According to the folder described in technical solutions 1, 2 or 3, in the invention described in technical solution 4, the storage part can be folded in half, and the other pieces are covers.

[0017] According to the folder described in technical solutions 1, 2, 3 or 4, in the invention described in technical solution 5, the bent portion is located at the lower end of the separator, and the fixing piece is fixed to the lower part of the other pieces.

[0018] According to the folder described in technical solutions 1, 2, 3, 4 or 5, in the invention described in technical solution 6, the storage part is mainly composed of the other pieces and a front piece disposed on the front side of the other pieces.

[0019] According to the folder described in technical solutions 1, 2, 3, 4, 5 or 6, in the invention described in technical solution 7, the storage part is foldable, and the plurality of partitions each have a half portion located on one side of the folded storage part and a half portion located on the other side. The bending part is provided only between the half portions on each side of the plurality of partitions, and the half portions on the other side are configured to be movable relative to each other.

[0020] According to the folder described in technical solution 7, in the invention described in technical solution 8, the folder is configured to be able to open and close between an unfolded position where the storage part is not folded and a closed position where the storage part is folded.

[0021] The relative movement is a left-right movement that accompanies the change in posture between the unfolded posture and the closed posture.

[0022] Invention Effects

[0023] As described above, according to the present invention, a folder with the following structure can be provided: at least one piece that has been bent at the bend to form multiple dividers can be properly fixed relative to the other pieces. Attached Figure Description

[0049] The following is for reference Figures 1-15 One embodiment of the present invention will be described. Furthermore, in the figures, the welded portion (welded area) is labeled with reference numeral y. Additionally, the terms left and right, up and down in the specification are shown for ease of explanation.

[0050] In this embodiment, the present invention is applied to a folder having a storage section sp that can hold documents such as paper P and can be folded in half.

[0051] The folder has a storage section sp that is configured to include a base sheet 4 as a front panel and a cover 1 as a rear panel located behind the base sheet 4 and is foldable.

[0052] The folder is configured to open and close between an unfolded position (T) where the storage section sp is not folded and a closed position (F) where the storage section sp is folded. That is, the folder has a cover 1 with a front cover 11 and a rear cover 12, and is configured to rotate around the central part in the left-right direction between an unfolded position (T) where the front cover 11 and the rear cover 12 are approximately coplanar and a closed position (F) where the inner surfaces of the front cover 11 and the rear cover 12 are approximately parallel to each other.

[0053] The folder comprises: a cover 1 having a front cover 11 as the left half and a rear cover 12 as the right half; a front divider 3 and a rear divider 2, which are multiple front and rear dividers disposed on the front side of the cover 1; a base sheet 4 disposed on the front side of the front divider 3; a pocket piece 5 disposed on the front side of the left half of the base sheet 4, i.e., the left half 41 of the base sheet, and cooperating with the left half 41 of the base sheet to form a pocket capable of holding items; and a retaining piece 6 disposed to cover the front and rear of the right half of the base sheet 4, i.e., the right half 42 of the base sheet, and retaining the right half 42 of the base sheet so as to suppress vertical movement of the right half 42 of the base sheet while allowing relative movement in the left and right directions.

[0054] The folder is equipped with first and second guide mechanisms G1 and G2. The first and second guide mechanisms G1 and G2 are guide mechanisms that guide the front half of the substrate, i.e. the right half of the base film 42, in a way that allows it to move relative to the rear half of the rear substrate, i.e. the rear cover 12, in a predetermined direction.

[0055] <Cover 1>

[0056] Cover 1 is roughly rectangular in shape. Cover 1 is made of other sheets, namely, sheets that are thicker than the front divider 3, the back divider 2, the base sheet 4, the pocket sheet 5, and the retaining sheet 6.

[0057] The cover 1 includes: a front cover 11, which is a generally elongated rectangle on the left side in an unfolded position (T); a rear cover 12, which is a generally elongated rectangle on the right side in an unfolded position (T); and a spine 13, which is a hinge portion between the front cover 11 and the rear cover 12.

[0058] A recessed portion 11a is formed at the upper edge of the front cover 11, which can engage with the rubber strip B provided on the spine 13 in the closed position (F). In addition, a notch portion 11b is formed at the upper edge of the front cover 11, which is formed by cutting out the position corresponding to the rear finger catch tab 21a protruding at the upper end of the rear partition 2 and the front finger catch tab 31a protruding at the upper end of the front partition 3.

[0059] On the rear cover 12, the two ends of a rubber band B for maintaining a closed position (F) are mounted on the outer surface via a known mounting mechanism. At the upper end of the rear cover 12, a recess 12a is formed, similar to that of the front cover 11, into which the rubber band B can engage.

[0060] The ridge seal 13 forms a hinged section. The ridge seal 13 has a pair of left and right inner fold lines m1 extending in the vertical direction and a pair of left and right outer fold lines m2 disposed on the outer sides of each of the left and right inner fold lines m1 and extending in the vertical direction. The ridge seal 13 includes: a ridge seal body 13a disposed between the left and right inner fold lines m1; and side end auxiliary parts 13b disposed on both sides of the ridge seal body 13a and located between the inner fold lines m1 and the outer fold lines m2.

[0061] <Rear divider 2 (divider)>

[0062] The rear partition 2, serving as a separator, is disposed at the front of the cover 1. The rear partition 2 is generally a horizontally elongated rectangular sheet. The rear partition 2 includes: a left half 21 of the rear partition, which, in the unfolded position (T), is a generally longitudinally elongated rectangle located on the left side; a right half 22 of the rear partition, which, in the unfolded position (T), is a generally longitudinally elongated rectangle located on the right side; and a rear partition hinge portion 23, which is a hinge portion located between the left half 21 and the right half 22 of the rear partition.

[0063] At the upper end of the left half 21 of the rear partition, a rear finger-holding protrusion 21a is provided, shaped for easy pinching by the user's fingers. At the lower part of the left half 21 of the rear partition, a fixing piece C, fused to the inner surface of the front cover 11, is provided. Furthermore, the structure of the fixing piece C will be described in detail later.

[0064] The right half 22 of the rear partition has a rear recess 22a that recesses the lower half of the right end edge toward the rear partition hinge 23. The rear recess 22a is provided to avoid interference with the right-side welded piece 66 of the retaining piece 6 that is welded to the lower half of the right end edge of the sealing ridge 13, and the right-side joint (Japanese: マチ) 65 that is disposed adjacent to the right-side welded piece 66.

[0065] The rear partition hinge portion 23 has a central broken line n1 extending in the vertical direction and left and right broken lines n2 arranged at approximately equal intervals in the horizontal direction.

[0066] The right half 22 and the hinge portion 23 of the rear partition 2 are not directly or indirectly fixed to the other parts. In other words, the right half 22 and the hinge portion 23 of the rear partition are fixed to the cover 1 by welding via the left half 21 of the rear partition.

[0067] <Front partition 3 (partition)>

[0068] The front partition 3 is positioned in front of the rear partition 2. The front partition 3 is generally a horizontally elongated rectangular piece. The front partition 3 includes: a left half 31, which is a generally longitudinally elongated rectangle located on the left side in the unfolded posture (T); a right half 32, which is a generally longitudinally elongated rectangle located on the right side in the unfolded posture (T); and a front partition hinge portion 33, which is a hinge portion located between the left half 31 and the right half 32 of the front partition.

[0069] At the upper end of the left half 31 of the front partition, a front finger tab 31a is provided, shaped for easy pinching by the user's fingers. Furthermore, when viewed from the front in the unfolded position (T), the front finger tab 31a is positioned offset to the right relative to the rear finger tab 21a. At the lower part of the left half 31 of the front partition, a perforation D is formed along with the fixing piece C.

[0070] The right half of the front partition plate 32 has a front end recess 32a that recesses the lower half of the right end edge towards the front partition plate hinge portion 33. The front end recess 32a is provided to avoid interference with the right-side welded piece 66 of the retaining piece 6 that is welded to the lower half of the right end edge of the sealing ridge 13, and the right-side joint 65 that is disposed adjacent to the right-side welded piece 66.

[0071] The front partition hinge portion 33 has central and left and right broken lines r1 and r2 that extend in the vertical direction and are arranged at approximately equal intervals in the left and right directions.

[0072] The right half 32 and the hinge portion 33 of the front partition 3 are not directly or indirectly fixed to other parts. In other words, the right half 32 and the hinge portion 33 of the front partition are fixed to the cover 1 via the left half 21 of the rear partition, which is continuously connected to the left half 31 of the front partition via a bend a1.

[0073]

[0074] The folder in this embodiment has a storage section sp that is divided into a front partition 3 and a rear partition 2 as dividers.

[0075] The front partition 3 and the rear partition 2, which serve as separators, are configured such that by... Figure 10 The sheet A shown is bent at the bend a1, which is a continuous boundary section, and overlaps with each other. Furthermore, a fixed sheet C, cut and erected from near the bend a1 in sheet A, is fused to the inner surface of the front cover 11, which is another sheet.

[0076] The fixing piece C is disposed to the left of the middle part of the front partition piece 3 and the rear partition piece 2 in the left-right direction, that is, to the left half 21 of the rear partition piece and the left half 31 of the front partition piece.

[0077] In other words, the two separators, namely the front separator 3 and the rear separator 2, are installed in the storage section sp by bending a sheet A at the bending portion a1. Furthermore, the fixing piece C, which is cut and erected from near the bending portion a1 of a sheet A, is fixed relative to the inner surface of the lower part of the front cover 11, which is another sheet, by welding.

[0078] By forming a roughly U-shaped slit a2 for forming a fixing piece, which extends across both sides of the lower ends of the left half 31 of the front dividing piece and the left half 21 of the rear dividing piece that constitute a sheet A, the fixing piece C is configured to be cut and erected from the side of the left half 21 of the rear dividing piece.

[0079] The slit a2 has a transverse slit a21 extending in a straight line in the left-right direction and a longitudinal slit a22 extending from both ends of the transverse slit a21 in a direction approximately orthogonal to the transverse slit a21 (the direction of the rear partition 2). The transverse slit a21 is provided on the left half 31 of the front partition, and the longitudinal slit a22 is provided throughout the left half 31 of the front partition and the left half 21 of the rear partition.

[0080] The base end of the fixing piece C is disposed on the left half 21 of the rear partition. A fixing piece bend c1, located at approximately the same height as the bend a1, is provided on the fixing piece C near the top end. The fixing piece C is bent using the fixing piece bend c1, resulting in a top portion c2 extending upwards from a position near the top end of the fixing piece bend c1. The top portion c2 of the fixing piece C is fused to the inner surface of the front cover 1 via the fused piece 53 on the lower side of the pocket piece 5.

[0081] The multiple dividers, namely the front divider 3 and the rear divider 2, have a left half of the front divider 31 and a left half of the rear divider 21 located on one side of the folded storage section sp, i.e. the left side, and a right half of the front divider 32 and a right half of the rear divider 22 located on the other side, i.e. the right side.

[0082] Furthermore, in this embodiment, a bending portion a1 is provided only between the half portions on one side of the front partition 3 and the rear partition 2, that is, only between the left half portion 31 of the front partition and the left half portion 21 of the rear partition. The right half portion 32 of the front partition and the right half portion 22 of the rear partition, which are the half portions on the other side, are arranged in a manner that allows them to move relative to each other.

[0083] In other words, a sheet A is configured such that only the left half 31 of the front separator and the left half 21 of the rear separator are connected by a bend a1, while the right half 32 of the front separator and the right half 22 of the rear separator are separated.

[0084] In addition, relative movement is left-right movement that accompanies the change in posture between the unfolded posture (T) and the closed posture (F).

[0085] <Film 4>

[0086] The substrate 4 is fixed relative to the pocket piece 5, which is fixed to the front cover 11, by welding. That is, the left half 41 of the substrate is indirectly fixed relative to the front cover 11 via the pocket piece 5.

[0087] The height of the substrate 4 is set to the value at the midpoint of its upper end in the vertical direction among the cover 1, the rear partition 2, and the front partition 3. More specifically, the substrate 4 is set to approximately half the height of the cover 1, the rear partition 2, and the front partition 3.

[0088] The folder is configured such that the height of the base sheet 4, which serves as the front cover, is lower than the heights of the cover 1, the rear divider 2, and the front divider 3, which serve as the rear cover. Therefore, as... Figure 14 As shown in one example, in the unfolded position (T), in order to check the contents stored in the storage section sp, the upper half of each of the front partition 3 and the rear partition 2 located behind the base plate 4 can be moved to the front side by the user's operation.

[0089] The substrate 4 is disposed in front of the front partition 3. The substrate 4 includes: a left half 41 of the substrate, which is a generally horizontally elongated rectangle located on the left side in the unfolded position (T); a right half 42 of the substrate, which is a generally horizontally elongated rectangle located on the right side in the unfolded position (T); a substrate hinge portion 43, which is a hinge portion between the left half 41 of the substrate and the right half 42 of the substrate; and a pocket flap forming piece 44, which is integrally provided from the upper edge of the left half 41 of the substrate.

[0090] A left-side welded piece 45 extends from the left end of the left half of the substrate 41. The left-side welded piece 45 is welded to the inner surface of the left end of the pocket piece 5, which is fixed to the front cover 11 by welding (more specifically, the inner surface of the left-side seam 54). The lower end of the left half of the substrate 41 is arranged in a manner that is either joined to or close to the inner surface of the pocket piece 5, which is fixed to the front cover 11 by welding.

[0091] A slit E extending in the vertical direction is provided on the right half 42 of the substrate, near the substrate hinge portion 43. A tongue 67 is inserted into the slit E, protruding from the retaining piece 6. The slit E and the tongue 67 constitute a first guide mechanism G1, which serves as a guide mechanism. Furthermore, the slit E and the tongue 67 are positioned where they are covered from the front by the front retaining piece portion 61 of the retaining piece 6.

[0092] The substrate hinge portion 43 has a central broken line s1 extending in the vertical direction and left and right broken lines s2 arranged at approximately equal intervals in the horizontal direction.

[0093] A fold-back tab 44a protrudes from the top of the pocket flap forming piece 44. The fold-back tab 44a is inserted into the slit 51b formed in the pocket piece 5. When the fold-back tab 44a is inserted into the slit 51b, the pocket flap forming piece 44 remains in a closed position. The fold-back tab 44a is fused to the inner surface of the pocket flap forming piece 44 near its base end while it is folded back along the inner surface side of the pocket flap forming piece 44.

[0094] The right half 42 and the hinged portion 43 of the substrate 4 are not directly or indirectly fixed relative to the other pieces. In other words, the right half 42 and the hinged portion 43 of the substrate are fixed to the cover 1 by being welded to the left half 41 of the substrate of the pocket piece 5.

[0095] <Pocket Card 5>

[0096] The pocket piece 5 can cooperate with the left half of the base piece 41 and the pocket flap forming piece 44 protruding above the left half of the base piece 41 to form a pocket that can hold items.

[0097] The pocket flap 5 comprises: a pocket flap body 51, the pocket flap body 51 having a window 51a with a transparent film fs for visual inspection of the interior, and a slit 51b extending in the left-right direction on the window 51a for insertion of a folding protrusion 44a provided on the pocket flap forming piece 44; a lower side joint 52, the lower side joint 52 being continuously provided from the lower edge of the pocket flap body 51; and a lower side welded piece 53, the lower side welded piece 53 extending from the extended end of the lower side joint 52 and fixed to the front cover 11 by welding. The lower end; a left-side joiner 54, which is continuously provided from the left end edge of the pocket piece body 51; a left-side welded piece 55, which extends from the extended end of the left-side joiner 54 and is fixed to the left end of the front cover 11 by welding; a right-side joiner 56, which is continuously provided from the right end edge of the pocket piece body 51; and a right-side welded piece 57, which extends from the extended end of the right-side joiner 56 and is fixed to the right end of the left half of the base sheet 41 by welding.

[0098] <Keep the film 6>

[0099] The retaining plate 6, as the third plate, can hold the right half 42 of the substrate so that it can move relative to each other in the left and right directions.

[0100] The retaining piece 6 includes: a front retaining piece portion 61 disposed in front of the right half portion 42 of the substrate; a rear retaining piece portion 62 continuously disposed from the upper edge of the front retaining piece portion 61 via a bent portion 6a serving as a fold-back portion, and disposed behind the right half portion 42 of the substrate and in front of the right half portion 32 of the front separator; a lower side joint 63 continuously disposed from the lower end edge of the front retaining piece portion 61; and a lower side welded piece 64, which is continuously disposed from the lower side... The extension end of the splice 63 extends and is fixed to the lower end of the rear cover 12 by welding; the right splice 65 is continuously provided from the right end edge of the front retaining piece 61; the right fused piece 66 extends from the extension end of the right splice 65 and is fixed to the right end of the rear cover 12 by welding; and the tongue 67 is continuously provided from the left end edge of the front retaining piece 61 via the fold-back portion 67b and disposed on the rear side of the front retaining piece 61.

[0101] The front retaining plate 61 is provided with a retaining slit 61a that extends obliquely in the left and right direction.

[0102] With the tongue 67 folded back along the inner surface of the front retaining piece 61, its base end is fused to the inner surface, i.e., the back surface, of the front retaining piece 61. The tongue 67 is inserted into the slot E provided in the right half of the substrate 42, and the right half of the substrate 42 is held in a position that allows relative movement of the right half of the substrate 42 in the left-right direction relative to the retaining piece 6 while restricting movement in the up-down direction.

[0103] At the upper part of the protruding end of the tongue 67, a protrusion 67a is provided to prevent the tongue 67 from dislodging from the slit E by engaging with the opening edge of the slit E. The protrusion 67a of the tongue 67 can define the limit position of the relative movement of the right half of the substrate 42 in the right direction relative to the tongue 67 when the substrate is in a closed position (F).

[0104] <First Guiding Mechanism G1 and Second Guiding Mechanism G2 (Guiding Mechanisms)>

[0105] The first and second guiding mechanisms G1 and G2 can guide the relative left-right movement of the first half of the front panel, i.e. the right half of the substrate 42, relative to the first half of the rear panel, i.e. the rear cover 12, during the change in posture between the unfolded posture (T) of the storage part sp and the closed posture (F) of the storage part sp folded in half, while suppressing the vertical offset movement of the right half of the substrate 42.

[0106] Furthermore, the second half of the front and rear side panels, namely the front cover 11 and the left half of the base sheet 41, are fixed to each other via the pocket piece 5. In other words, the front cover 11 and the left half of the base sheet 41 are structured to be almost unable to move relative to each other in the left-right direction.

[0107] The first guiding mechanism G1 consists of a slit E and a tongue 67. The slit E is located in the right half of the substrate 4, which serves as the front side sheet. The tongue 67 is indirectly located in the right half of the rear side sheet, i.e., the rear cover 12, via a retaining piece 6, and is inserted into the slit E, which extends in the vertical direction and is formed in the right half of the substrate 42, and can move forward and backward in the horizontal direction.

[0108] The second guiding mechanism G2 has the following structure: it has a retaining piece 6, which is fixed to the right half of the cover 1, which is the rear cover 12, as the rear side sheet, by welding, and the upper edge je of the right half of the front side sheet, which is the right half of the base sheet 42, can engage with the bent portion 6a formed between the front retaining piece portion 61 and the rear retaining piece portion 62 of the retaining piece 6.

[0109] <Relative position of the hinge>

[0110] On the cover 1, between the front cover 11, located on one side of the folded storage section sp, and the rear cover 12, located on the other side, a ridge 13 serving as a hinge is provided, which has multiple fold lines, namely inner fold lines m1 and outer fold lines m2.

[0111] In the rear partition 2, between the left half of the rear partition 21 located on one side of the folded storage section sp and the right half of the rear partition 22 located on the other side, a rear partition hinge section 23 is provided, which has multiple bend lines, namely a central bend line n1 and left and right bend lines n2, serving as a hinge section.

[0112] Between the left half of the front partition 3, located on one side of the folded storage section sp, and the right half of the front partition 3, located on the other side, a hinged part 33 is provided, which has multiple bends, namely a central bend r1 and left and right bends r2.

[0113] In the substrate 4, between the left half of the substrate 41, located on one side of the folded storage part sp, and the right half of the substrate 42, located on the other side, a substrate hinge part 43 is provided, which has multiple bends, namely a central bend s1 and left and right bends s2, serving as a hinge part.

[0114] In this embodiment, in the unfolded position (T), the spine 13, the rear partition hinge 23, the front partition hinge 33, and the substrate hinge 43 are arranged sequentially from back to front. Furthermore, the spine 13, the rear partition hinge 23, the front partition hinge 33, and the substrate hinge 43 are positioned at a relatively offset location in the unfolded position (T).

[0115] More specifically, when viewed from the front in the unfolded posture (T), a rear partition hinge 23, which serves as a hinge, is disposed at a position offset to the left of the ridge 13, which serves as a hinge; a front partition hinge 33, which serves as a hinge, is disposed at a position offset to the left of the rear partition hinge 23; and a base plate hinge 43, which serves as a hinge, is disposed at a position offset to the left of the front partition hinge 33.

[0116] In other words, within the folder, a first hinge portion (rear partition hinge portion 23, front partition hinge portion 33, or base plate hinge portion 43) with multiple bends or folds is provided between one half of the front panel and the other half of the front panel, and a second hinge portion (ridge 13, rear partition hinge portion 23, or front partition hinge portion 33) with multiple bends or folds is provided between one half of the rear panel and the other half of the rear panel. Furthermore, the first hinge portion, which is located forward of the second hinge portion when viewed from the front in the unfolded posture (T), is positioned to the left of the second hinge portion, which is located rearward of the first hinge portion, when viewed from the front in the unfolded posture (T).

[0117] In addition, the separation dimensions between the left and right inner fold lines m1 in the ridge 13, the separation dimensions between the inner fold line m1 and the outer fold line m2, the separation dimensions between the central fold line n1 and the left and right fold lines n2 in the rear partition hinge 23, the separation dimensions between the central fold line r1 and the left and right fold lines r2 in the front partition hinge 33, and the separation dimensions between the central fold line s1 and the left and right fold lines s2 in the substrate hinge 43 are set to be different from each other.

[0118] As explained above, the folder of this embodiment includes a storage section sp that divides the space using a front partition 3 and a rear partition 2 as dividers. Furthermore, multiple front partitions 3 and rear partitions 2 are provided in the storage section sp by bending a sheet A at the bending portion a1.

[0119] Furthermore, a sheet-like fixing piece C is provided near the bend a1 in the front partition 3 and the rear partition 2. The fixing piece C is disposed to the left of the middle part in the left-right direction of the front partition 3 and the rear partition 2, that is, to the left half 21 of the rear partition and the left half 31 of the front partition, and the fixing piece C is fixed to the cover 1, which is another piece.

[0120] Therefore, if it is the folder of this embodiment, it becomes the following structure: a piece A, which is formed by bending at the bending part a1 to form multiple partitions, namely the front partition 3 and the rear partition 2, can be properly fixed relative to the cover 1.

[0121] Furthermore, since the fixing piece C, which is fixed to the cover 1, is positioned to the left, i.e. to the left half 21 of the rear divider and the left half 31 of the front divider, the freedom and flexibility of movement of the front divider 3 and the rear divider 2, either as a whole or in part, can be appropriately improved as a result of the opening and closing of the cover 1.

[0122] Since the fixing piece C, which is cut and erected from near the bend a1 in sheet A, is fixed relative to the cover 1 which is another sheet, the fixing piece C is properly positioned on sheet A.

[0123] In other words, since the fixing piece C, which is cut and erected from near the bend a1 in a sheet A, is fixed relative to the cover 1, the fixing piece C is less likely to become an obstacle to the document P stored in the storage section sp, and the document P can be properly stored inside.

[0124] By creating a roughly コ-shaped slit a2 on a piece A, piece C is fixed in a way that allows it to be cut and stood up.

[0125] Therefore, it is possible to easily form a fixed piece C from a piece A.

[0126] Because the folder is a foldable folder from the storage department, it can be made compact when moving or transporting items.

[0127] The bent part a1 is located at the lower end of the front partition 3 and the rear partition 2, and the fixing piece C is fixed to the lower part of the cover 1.

[0128] Therefore, the fixing piece C used to fix the front divider 3 and the rear divider 2 is positioned in a suitable location that does not obstruct the storage of the document P.

[0129] The storage section sp is mainly composed of a cover 1 and a base sheet 4, which is disposed on the front side of the cover 1 as a front panel.

[0130] Therefore, the storage part sp can be properly formed between the cover 1 and the substrate 4.

[0131] The storage section sp can be folded in half. The multiple dividers, namely the front divider 3 and the rear divider 2, each have a front divider left half 31 and a rear divider left half 21 that are half of the divider located on one side of the folded storage section sp, and a front divider right half 32 and a rear divider right half 22 that are half of the divider located on the other side. A bending portion a1 is provided only between the front divider left half 31 and the rear divider left half 21. The front divider right half 32 and the rear divider right half 22 are arranged in a way that allows them to move relative to each other.

[0132] Therefore, even when the storage section sp is folded in half, by moving the right half of the front divider 32 and the right half of the rear divider 22 relative to each other, it is possible to properly fold the entire folder in half.

[0133] It is configured to open and close between an unfolded position (T) where the storage part sp is not folded and a closed position (F) where the storage part sp is folded. The relative movement is a left-right movement that occurs as the posture changes between the unfolded position (T) and the closed position (F).

[0134] Therefore, the right half of the front divider 32 and the right half of the rear divider 22 can move relative to each other in the left and right direction along the direction of the user's natural left and right opening and closing operation of the folder.

[0135] Furthermore, the present invention is not limited to the embodiments detailed above.

[0136] Of course, the guiding mechanism can adopt various structures.

[0137] For example, the guiding organization can also be Figure 16 The structure shown.

[0138] Figure 16 The image shows a holder for binding a file folder. The holder holds the document P within the storage section sp. The holder has a storage section sp configured to include a front holder 7 (as a front panel) and a rear holder 8 (as a rear panel), and can be folded in half vertically at the center. The holder has a binding foot insertion hole 8a at the side end of the rear holder 8 and is supported by a file folder body equipped with binding feet (not shown).

[0139] The front retaining piece 7 has a lower half 71 located on one side (the lower side) of the folded storage section sp and an upper half 72 located on the other side (the upper side). The rear retaining piece 8 has a lower half 81 located on one side (the lower side) of the folded storage section sp and an upper half 82 located on the other side (the upper side).

[0140] The lower half of the front retaining plate 71 and the lower half of the rear retaining plate 81 are fixed to each other at the welded part y1 located on the right side. The upper half of the front retaining plate 72 and the upper half of the rear retaining plate 82 are configured to move relative to each other in a predetermined direction by means of the guide mechanism G3.

[0141] A guide mechanism G3 is provided between the upper half 72 of the front retaining plate and the upper half 82 of the rear retaining plate to guide the two plates in a manner that allows them to move relative to each other. The guide mechanism G3 includes: a track portion 72a, which is disposed on the side of the upper half 72 of the front retaining plate and extends in the vertical direction; and a track-holding (enclosing clamping) portion 82a, which is disposed on the upper half 82 of the rear retaining plate and holds the track portion 72a in a manner that allows it to move relative to each other in the vertical direction. Even with this structure, the desired purpose can be achieved.

[0142] The shape of the fixing piece can be various and is not limited to the shape shown in the above embodiments.

[0143] The fixing plate is not limited to a fixing plate that is set by cutting and erecting. For example, a fixing plate that is a component of another component can also be installed on the plate by welding or the like, thereby setting a fixing plate on the plate.

[0144] The fixed piece can be cut and erected only near the bend, and the specific location can be set in various ways.

[0145] The slit used to form the fixing piece is not limited to a roughly U-shaped form. The slit only needs to be shaped enough to cut the fixing piece upright, and the specific shape can be set in various ways.

[0146] A folder can also be a folder that cannot be folded in half.

[0147] Furthermore, the specific structure of each part is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
