[0017] An embodiment of the present invention will now be described with reference to Figures 1 to 13. In the figures, the welded portion (welded section) is designated by the symbol y.

[0018] In this embodiment, the present invention is applied to a file that is configured to be able to take an unfolded position (T) and a folded position (F) that is folded in half from the unfolded position (T).

[0019] The file comprises a cover A, first and second binding pieces C and D which are a pair of independent foldable binding pieces integrally formed on the edge of the cover A, clear pockets E which are multiple storage members bound by first and second binding feet G and H which are binding members formed on the first and second binding pieces C and D, and a holder J which is a storage body arranged on top of multiple stacked clear pockets E and bound together with the clear pockets E by the first and second binding feet G and H.

[0020] The file is configured so that the cover A, the clear pocket E, and the holder J can be folded in half as a unit so that the file can take a folded position (F).

[0021] <Cover A> The cover A has a front cover a1 and a back cover a2 connected via a spine a3, which is a hinge portion. The cover A is configured to be able to take an unfolded position (T) in which the front cover a1 and the back cover a2 are unfolded so that they are substantially flush with each other, and a folded position (F) in which the inner surfaces of the front cover a1 and the back cover a2 face each other via the pocket file and holder J.

[0022] The cover A has a substantially vertically elongated rectangular shape in the unfolded position (T). The cover A includes a front cover a1 having a substantially horizontally elongated rectangular shape that constitutes the upper half in the unfolded position (T), a back cover a2 having a substantially horizontally elongated rectangular shape that constitutes the lower half in the unfolded position (T), and a spine a3 that serves as a hinge portion provided between the back cover a2 and the front cover a1.

[0023] The front cover a1 is approximately the same size as the back cover a2. The right edge of the front cover a1 is provided with a recessed portion a11 that engages with a bundling rubber band B attached to the back cover a2 when the cover is in the folded position (F).

[0024] The back cover a2 is approximately the same size as the front cover a1. A rubber band B is attached to the back cover a2 to bind the front cover a1 and back cover a2 together when in the folded position (F). A recess a21 is provided on the right side edge of the back cover a2 to engage with the rubber band B when in the folded position (F).

[0025] The spine a3 as a whole constitutes the hinge portion. The spine a3 has a pair of upper and lower inner fold lines m1 extending in the left-right direction, and a pair of upper and lower outer fold lines m2 extending in the left-right direction and disposed on the outside of each of the pair of upper and lower inner fold lines m1. The spine a3 has a spine main body a31 disposed between the pair of upper and lower inner fold lines m1, and upper auxiliary portions a32 and lower auxiliary portions a33 disposed above and below the spine main body a31 and positioned between the inner fold lines m1 and the outer fold lines m2.

[0026] <Binding Pieces (First Binding Piece C, Second Binding Piece D)> The first binding piece C extends integrally from the left edge, which is the edge on the binding origin side, of the front cover a1. The first binding piece C extends from the part of the left edge of the front cover a1 in the unfolded position (T) excluding the lower part. In other words, the first binding piece C protrudes from a part of the left edge of the front cover a1.

[0027] The first binding piece C has a vertically long belt shape. The first binding piece C includes a first binding piece body c1 provided with a pair of upper and lower binding foot insertion holes c11 through which the first binding feet G are inserted, and a first bending portion c2 which is a bending portion that is provided on one side edge of the first binding piece body c1 and is a bendable portion that connects the first binding piece body c1 and the front cover a1.

[0028] The first binding piece C is configured so that the first binding piece main body c1 can be folded back toward the inner side of the front cover a1. The first binding piece main body c1 is connected to the front cover a1 via a first bent portion c2, and the portion other than the first bent portion c2 is not constrained by the front cover a1.

[0029] The first binding piece C is bent at the first bending portion c2, and the basic position is one in which the first binding piece main body c1 is folded back toward the inner surface of the front cover a1. The welded end gt of the first binding foot G supported by the first binding piece C is positioned between the first binding piece main body c1 and the inner surface of the front cover a1.

[0030] The first binding piece body c1 has a support surface c12 that faces the clear pocket E, which is the object to be bound, and can support the retained end portion e2 of the clear pocket E, and a proximate opposing surface c13 that faces the inner surface of the front cover a1 at a position close to the inner surface of the front cover a1.

[0031] The first bent portion c2 has folding lines c21 extending in the vertical direction and provided in pairs on the left and right.

[0032] The second binding piece D extends integrally from the left edge of the back cover a2, which is the edge on the binding origin side. The second binding piece D extends from the back cover a2 in the unfolded position (T) excluding the upper part of the left edge. In other words, the second binding piece D protrudes from a part of the left edge of the back cover a2.

[0033] The second binding piece D has a vertically long belt shape. The second binding piece D includes a second binding piece body d1 provided with a pair of upper and lower binding foot insertion holes d11 through which the second binding feet H are inserted, and a second bending portion d2 that is a bending portion that is provided on one side edge of the second binding piece body d1 and is a bendable portion that connects the second binding piece body d1 and the back cover a2.

[0034] The second binding piece D is configured so that the second binding piece main body d1 can be folded back to the inside side of the back cover a2. The second binding piece main body d1 is connected to the back cover a2 via the second bent portion d2, and the portion other than the second bent portion d2 is not constrained to the back cover a2.

[0035] The second binding piece D is bent at the second bending portion d2, and the second binding piece main body d1 is folded back toward the inner surface of the back cover a2, which is its basic position. The welded end ht of the second binding foot H supported by the second binding piece D is positioned between the second binding piece main body d1 and the inner surface of the back cover a2.

[0036] The second binding piece body d1 has a support surface d12 facing the clear pocket E, which is the object to be bound, and capable of supporting the retained end portion e2 of the clear pocket E, and a proximate opposing surface d13 facing the inner surface of the back cover a2 at a position close to the inner surface of the back cover a2.

[0037] The second bent portion d2 has folding lines d21 extending in the vertical direction and provided in pairs on the left and right.

[0038] The first binding piece C and the second binding piece D connected to the cover A are provided independently. That is, the first binding piece C and the second binding piece D are provided spaced apart from each other.

[0039] A document P can be temporarily held between the cover A and the first and second binding pieces C, D.

[0040] The first and second binding pieces C, D can assume an inclined position relative to the cover A when the holder J is turned over so as to be positioned on the outer surface side of the cover A in the unfolded position (T).

[0041] That is, in the unfolded position (T), when the user turns over the holder J so that part of it is located on the outer surface side of the cover sheet A, the holder main body JH, which is formed by overlapping the base sheet main body 11 and the cover sheet 2, is located on the outer surface side of the cover sheet A. At this time, the outer hinge portion 122 and the inner hinge portion 121 of the extension portion 12, which is connected to the base sheet main body 11 of the holder main body JH and supported by the first and second binding feet G and H, are each bent, and the vertically long strip-shaped portion between the outer hinge portion 122 and the inner hinge portion 121 of the extension portion 12 covers the upper sides of the first and second binding feet G and H, and the inner hinge portion 121 covers the outside of the first and second bent portions c2 and d2 adjacent to the cover sheet A.

[0042] In other words, when the holder main body JH moves toward the outer surface of the cover A, the extension portion 12 pulls up the first and second binding pieces C and D via the first and second binding feet G and H so that they assume an inclined position relative to the cover A.

[0043] <Binding foot (first binding foot G, second binding foot H)> The clear pocket E and the holder J are bound by first and second binding feet G and H, which are binding members supported by first and second binding pieces C and D. In this embodiment, the first and second binding feet G and H are each belt-shaped. The base ends of the first and second binding feet G and H are welded together to form a closed loop.

[0044] The welded end gt of the first binding foot G is disposed between the adjacent facing surface c13 of the first binding piece body c1 and the inner surface of the front cover a1. The welded end ht of the second binding foot H is disposed between the adjacent facing surface d13 of the second binding piece body d1 and the inner surface of the back cover a2.

[0045] <Clear Pocket E> The clear pocket E includes a pocket body e1 that can accommodate documents P through an opening e11 therein, and a retained end e2 that is provided along the left end, which is one end of the pocket body e1, and that has a first binding foot insertion hole e21 and a second binding foot insertion hole e22 through which the first and second binding feet G and H are inserted. In this embodiment, the opening e11 is provided in the pocket body e1 so as to be aligned with the retained end e2.

[0046] The clear pocket E is capable of changing its position in accordance with the change in position of the cover A. In other words, when the cover A is folded in half, the clear pocket E is configured to bend in the vertical center to follow the cover A and be foldable in half.

[0047] The held end e2 has a strip shape extending in the vertical direction. An upper half of the held end e2 is provided with a pair of upper and lower first binding foot insertion holes e21 through which the first binding feet G are inserted. A lower half of the held end e2 is provided with a pair of upper and lower second binding foot insertion holes e22 through which the second binding feet H are inserted.

[0048] The second binding foot insertion hole e22 is a long hole extending in the vertical direction, and is configured so that when the cover A is folded in half, the lower half of the clear pocket E can flexibly move in the vertical direction relative to the back cover a2.

[0049] <Holder J> The holder J, which is a storage body, is configured to easily hold and hold documents P. The holder J includes a base sheet 1 and a cover sheet 2. Between the base sheet 1 and the cover sheet 2, the holder J has a storage space sp formed therein in which documents P can be stored.

[0050] The holder J, together with a plurality of clear pockets E, is stacked on the inner surface of the cover A via first and second binding feet G and H supported by first and second binding pieces C and D. The holder J is positioned at the top (front) in the unfolded position (T).

[0051] In other words, the holder J is located at the top (front) in the unfolded position (T) and can function as a cover in the unfolded position (T) by covering and hiding the multiple clear pockets E from above (front).

[0052] The holder J comprises a base sheet 1, which is a first sheet body having a first bent portion N extending in the left-right direction at the middle of the vertical direction, and a cover sheet 2, which is a second sheet body superimposed in front of the base sheet 1 and having a second bent portion R extending in the left-right direction at the middle of the vertical direction corresponding to the first bent portion N.

[0053] The base sheet 1 includes a base sheet main body 11 having a vertically long rectangular shape in the unfolded position (T), and an extension part 12 extending from the left end of the base sheet main body 11 on the binding origin side.

[0054] The base sheet 1 has a first bent portion N in the vertical center in the unfolded posture (T). The first bent portion N includes a central fold line n1 that extends linearly in the left-right direction, and upper and lower fold lines n2 that are arranged above and below the central fold line n1 and also extend linearly in the left-right direction.

[0055] The first bent portion N is provided across the entire width between both left and right ends of the base sheet 1. In other words, the first bent portion N is provided in the vertical middle portion of each of the base sheet main body 11 and the extension portion 12. In the unfolded posture (T), the base sheet 1 has an upper half portion 1a above the first bent portion N and a lower half portion 1b below the first bent portion N.

[0056] As shown in Figure 8, the first bend portion N has an approximately flat posture in the unfolded posture (T) in which the central fold line n1 and the left and right fold lines n2 are positioned on approximately the same horizontal line, and is configured so that in the folded posture (F) in which the central fold line n1 is positioned outside the left and right fold lines n2, forming a valley fold shape, as shown in Figure 9.

[0057] The base sheet main body 11 cooperates with the cover sheet 2 to form the holder main body JH having a storage space sp capable of storing documents P. The base sheet main body 11 has a first bent portion N between an upper half portion 111 and a lower half portion 112.

[0058] A holding piece 113 is disposed at the upper left corner of the base sheet main body 11, capable of holding the upper left corner, which is the free end of the cover sheet 2. The holding piece 113 is a piece-like piece that extends integrally from the upper edge of the base sheet main body 11, is folded back toward the front side of the base sheet main body 11, and has its left end welded to the left end of the base sheet main body 11. The cover sheet 2 is connected to the right end and bottom end of the base sheet main body 11 either integrally or by welding.

[0059] The extension portion 12 includes an inner hinge portion 121 extending in the vertical direction along the left end portion of the base sheet main body 11, an outer hinge portion 122 positioned outside the inner hinge portion 121 and arranged approximately parallel to the inner hinge portion 121, a pair of upper and lower first binding foot insertion holes 13 which are binding foot insertion holes arranged outside the outer hinge portion 121 in the upper half, and a pair of upper and lower second binding foot insertion holes 14 which are binding foot insertion holes arranged outside the outer hinge portion in the lower half.

[0060] The extension portion 12 constitutes a holder body support portion that supports the holder body JH, which is mainly composed of the base sheet body 11 and the cover sheet 2.

[0061] An upper portion of the extension portion 12 is provided with a pair of upper and lower first binding foot insertion holes 13 through which the first binding feet G are inserted. An upper portion of the extension portion 12 is provided with a pair of upper and lower second binding foot insertion holes 14 through which the second binding feet H are inserted. The second binding foot insertion holes 14 are elongated holes extending in the vertical direction, and are configured so that when the cover A is folded in half, the lower half of the holder J can easily move in the vertical direction relative to the back cover a2.

[0062] The cover sheet 2 is set to be approximately the same size as the base sheet main body 11. The cover sheet 2 is capable of covering the base sheet main body 11 from the front side. The right end and bottom end of the cover sheet 2 are connected to the base sheet main body 11 either integrally or by welding.

[0063] The cover sheet 2 has an upper half 21 having a horizontally elongated rectangular shape, a lower half 22 having a horizontally elongated rectangular shape, a second bent portion R arranged between the upper half 21 and the lower half 22, and a cutout portion 23 for avoiding continuity between the right edge of the second bent portion R and the base sheet main body 11.

[0064] The second bent portion R is provided in the vertical center of the cover sheet 2 in the unfolded posture (T). The second bent portion R includes a plurality of fold lines, namely, a central fold line r1 that extends linearly in the left-right direction, and upper and lower fold lines r2 that are arranged above and below the central fold line r1 and also extend linearly in the left-right direction.

[0065] 9, the second bent portion R is configured to be bent in a direction away from the first bent portion N in the folded posture (F). More specifically, the second bent portion R is configured to be bent in a mountain-like shape in which the central fold line r1 is located more inward than the left and right fold lines r2 in the folded posture (F).

[0066] In this embodiment, the second bent portion R does not have a flat shape in the unfolded posture (T), but has a gentler mountain-fold shape than in the folded posture (F). That is, even in the unfolded posture (T), the second bent portion R maintains a mountain-fold shape in which the central fold line r1 is located more inward than the left and right fold lines r2.

[0067] In holder J, the base sheet 1 and cover sheet 2 can take a folded position (F) and an unfolded position (T) with first and second bends N and R as rotation centers. In other words, holder J is capable of changing its position in response to changes in the position of cover A. In other words, holder J is configured so that when cover A is folded in half, it can be bent at the first and second bends N and R located in the vertical center to follow cover A and be folded in half.

[0068] When the holder J assumes the folded position (F) in accordance with a change in the position of the cover A, the central fold line n1 of the first bent portion N and the central fold line r1 of the second bent portion R are spaced apart significantly, as shown in Figure 9. At this time, the upper and lower fold lines r2 of the second bent portion R can move in directions that bring them closer to each other.

[0069] For this reason, in the folded position (F), a relatively large bent portion space sk is secured between the first bent portion N and the second bent portion R of the holder J, in which the bent portion pe of the sandwiched document P is disposed. In other words, even in the folded position (F), the holder J can form a spacious bent portion space sk between the first and second bent portions N and R that can accommodate the bent portion pe of the document P, and therefore can suitably accommodate a relatively large number of documents P.

[0070] As described above, the file according to this embodiment includes a cover A and a clear pocket E serving as a storage member bound to the cover A by first and second binding feet G and H serving as binding members.

[0071] The edge of the cover A is integrally provided with first and second binding pieces C and D, which are foldable binding pieces, and a clear pocket E is bound by first and second binding feet G and H supported by the first and second binding pieces C and D.

[0072] Therefore, the file of this embodiment has a configuration in which the welded ends, which are part of the first and second binding feet G and H, are unlikely to be exposed from the outer surface side of the cover A.

[0073] The first and second binding pieces C and D are connected to the cover A via the first bending portion c2 and the second bending portion d2, and the portions other than the first and second bending portions c2 and d2 are not constrained to the cover A.

[0074] For this reason, the first and second binding pieces C and D are supported in a cantilever manner relative to the cover A via the first and second bending portions c2 and d2, and can therefore move flexibly in accordance with the movements of the clear pocket E and holder J.

[0075] The cover A and the clear pocket E are configured so as to be foldable in half as a unit.

[0076] This allows documents P to be stored comfortably in the clear pocket E, and by folding it in half, the entire file can be made compact and easy to carry around.

[0077] The cover A has a front cover a1 and a back cover a2 connected via a spine a3, which is a hinge portion. The cover A is configured to be able to take two positions: an unfolded position (T) in which the front cover a1 and the back cover a2 are unfolded so that they are substantially flush with each other, and a closed position in which the inner surfaces of the front cover a1 and the back cover a2 face each other via a clear pocket E. In the unfolded position (T), when the holder J is turned over so that it is positioned on the outer surface side of the cover A, the first and second binding pieces C and D are inclined relative to the cover A.

[0078] Therefore, by placing the first and second binding pieces C and D in an inclined position, the opening e11 of the clear pocket E can be easily and smoothly accessed.

[0079] The cover A has a front cover a1 and a back cover a2 connected via a spine a3, a first binding piece C is provided on the front cover a1, and a second binding piece D is provided on the back cover a2.

[0080] Therefore, the first binding piece C and the second binding piece D are configured to be spaced apart, so that the cover A, base sheet 1, and holder J can be conveniently folded in half at the middle in the vertical direction.

[0081] That is, the first binding piece C and the second binding piece D are spaced apart from each other, so that they are less likely to interfere with each other when the position is changed between the unfolded position (T) and the folded position (F).

[0082] The book is provided with first and second band-shaped binding feet G and H, and the first and second binding pieces C and D are provided with binding foot insertion holes c11 and d22 through which the first and second binding feet G and H are inserted. This allows the cover A to suitably support multiple clear pockets E and holders J.

[0083] The present invention is not limited to the above-described embodiment.

[0084] The binding member is not limited to the binding feet shown in the above-described embodiment, but may be of any configuration as long as it is capable of binding the storage member or storage body.

[0085] Furthermore, the storage member or storage body may be anything that can store documents, and is not limited to the clear pockets or holders shown in the above-described embodiments.

[0086] The binding strip is not limited to being provided in multiple pieces on the cover, but may be provided with a single piece on the cover, for example.

[0087] The binding foot is not limited to a belt-like shape, but may be, for example, a string-like shape.

[0088] Furthermore, the specific configuration of each part is not limited to the above embodiment, and various modifications are possible within the scope of the present invention. [Explanation of symbols]
