Description

Technical Field

[0001] This invention relates to folders capable of containing files. Background Technology

[0002] Previously, there were known transparent holders that used binding members to support the storage bag on the cover and were foldable (for example, see Patent Document 1).

[0003] Conventional transparent retainers are configured such that a portion of the binding component supported on the cover protrudes to the outer surface of the cover through a binding component insertion hole provided in the cover. Therefore, the binding component not only detracts from the appearance of the outer surface of the cover but also easily gets caught on furniture or surrounding items.

[0004] Furthermore, the above situation is not limited to transparent retainers, but also applies to the entire folder.

[0041] The following is for reference Figures 1-13 One embodiment of the present invention will be described. Furthermore, in the figures, the welded portion (welded area) is labeled with reference numeral y.

[0042] This embodiment applies the invention to a folder configured to be able to take an unfolded posture (T) and a folded posture (F) from the unfolded posture (T).

[0043] The folder comprises: a cover A; first and second binding sheets C and D, which are independent pairs of binding sheets integrally formed with the end edge of the cover A and capable of being folded back; a plurality of transparent pockets E serving as storage components, which are bound together by first and second binding feet G and H provided on the first and second binding sheets C and D; and a retainer J, which is a storage body disposed on the plurality of overlapping transparent pockets E and bound together with the transparent pockets E by the first and second binding feet G and H.

[0044] The folder is constructed such that the cover A, the transparent pocket E, and the retainer J can be folded together to allow for a folded posture (F).

[0045] <Cover A>

[0046] Cover A has a front cover a1 and a rear cover a2 connected by a spine a3, which serves as a hinge. Cover A is configured to be able to be unfolded in an unfolded position (T) in which the front cover a1 and the rear cover a2 can be unfolded in a substantially coplanar manner, and to be folded in a position (F) in which the inner surfaces of the front cover a1 and the rear cover a2 can face each other with a pocket file and a retainer J between them.

[0047] Cover A is generally longitudinally elongated rectangular in its unfolded position (T). Cover A includes: a front cover a1 that is generally transversely elongated rectangular in its upper half in the unfolded position (T), a rear cover a2 that is generally transversely elongated rectangular in its lower half in the unfolded position (T), and a spine a3 that serves as a hinge between the rear cover a2 and the front cover a1.

[0048] The front cover a1 is formed to be approximately the same size as the rear cover a2. A recess a11 is provided on the right end edge of the front cover a1, which engages with the rubber strap B for binding attached to the rear cover a2 when in the folded position (F).

[0049] The rear cover a2 is formed to be approximately the same size as the front cover a1. A rubber band B is installed on the rear cover a2 for binding the front cover a1 and the rear cover a2 when in the folded position (F). A recess a21 is provided on the right end edge of the rear cover a2 to engage with the rubber band B when in the folded position (F).

[0050] The spine back a3 constitutes the hinge portion as a whole. The spine back a3 is provided with a pair of upper and inner folding lines m1 extending in the left-right direction, and a pair of upper and outer folding lines m2 respectively disposed on the outer sides of the pair of upper and lower inner folding lines m1 and extending in the left-right direction. The spine back a3 comprises: a spine back main body a31, which is disposed between the pair of upper and lower inner folding lines m1; and an upper auxiliary portion a32 and a lower auxiliary portion a33, which are disposed above and below the spine back main body a31 and located between the inner folding lines m1 and the outer folding lines m2.

[0051] <binding sheet (first binding sheet C, second binding sheet D)>

[0052] The first binding sheet C integrally extends from the left end edge, which is the end edge on the binding start side (Japanese: 綴じ元側) of the front cover a1. The first binding sheet C extends from a portion of the front cover a1 in the unfolded posture (T) excluding the lower part of the left end edge. That is, the first binding sheet C protrudes from a part of the left end edge of the front cover a1.

[0053] The first binding sheet C is in the shape of a vertically long strip. The first binding sheet C comprises: a first binding sheet main body c1, which is provided with a pair of upper and lower binding leg insertion holes c11 for a first binding leg G to pass through; and a first bending portion c1 serving as a bending part, which is disposed on one side edge of the first binding sheet main body c1 and is a bendable part connecting the first binding sheet main body c1 and the front cover a1.

[0054] The first binding sheet C is configured to enable the first binding sheet main body c1 to be folded back toward the inner surface side of the front cover a1. The first binding sheet main body c1 is continuously provided relative to the front cover a1 via the first bending portion c2, and portions other than the first bending portion c2 are not constrained relative to the front cover a1.

[0055] The first binding sheet C is bent by the first bending portion c2, and takes the posture where the first binding sheet main body c1 is folded back toward the inner surface side of the front cover a1 as the basic posture. The welded end gt of the first binding leg G supported by the first binding sheet C is located between the first binding sheet main body c1 and the inner surface of the front cover a1.

[0056] The first binding sheet main body c1 comprises: a support surface c12, which faces the transparent pocket E as a bound body and can support the held end e2 of the transparent pocket E; and a close opposing surface c13, which opposes the inner surface of the front cover a1 at a position close to the inner surface side of the front cover a1.

[0057] The first bending portion c2 is provided with folding lines c21 extending in the vertical direction and arranged in pairs on the left and right.

[0058] The second binding piece D extends integrally from the left edge of the end edge that serves as the binding start side in the back cover a2. The second binding piece D extends from the portion of the back cover a2 in the unfolded position (T) except for the upper part of the left edge. That is, the second binding piece D protrudes from a portion of the left edge of the back cover a2.

[0059] The second binding sheet D is a longitudinal strip. The second binding sheet D includes: a second binding sheet body d1, which is provided with a pair of upper and lower binding foot insertion holes d11 for the second binding foot H to be inserted; and a second bending portion d2 as a bending portion, which is a bendable part provided on one side edge of the second binding sheet body d1 and connecting the second binding sheet body d1 with the back cover a2.

[0060] The second binding piece D is configured to fold the second binding piece body d1 back towards the inner surface of the rear cover a2. The second binding piece body d1 is continuously disposed relative to the rear cover a2 via a second bend d2, and the portion other than the second bend d2 is not constrained relative to the rear cover a2.

[0061] The second binding piece D is bent using the second bending portion d2, with the basic posture being that the second binding piece body d1 is folded back towards the inner surface of the rear cover a2. The welded end ht of the second binding leg H, supported by the second binding piece D, is located between the second binding piece body d1 and the inner surface of the rear cover a2.

[0062] The second binding sheet body d1 has: a support surface d12 facing the transparent pocket E, which is the binding body, and capable of supporting the held end e2 of the transparent pocket E; and a proximity 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.

[0063] The second bending portion d2 has a broken line d21 that extends in the vertical direction and is arranged in pairs in the left and right directions.

[0064] The first binding sheet C and the second binding sheet D, which are continuously arranged with the cover A, are arranged independently. That is, the first binding sheet C and the second binding sheet D are arranged separately from each other.

[0065] The document P can be temporarily held between the cover A and the first and second binding sheets C and D.

[0066] When the first and second binding pieces C and D are in the unfolded position (T), and are opened with the retainer J located on the outer surface of the cover A, they can be tilted relative to the cover A.

[0067] That is, in the unfolded position (T), when the user flips the cover open with a portion of the retainer J located on the outer surface of the cover A, the retainer body JH, which is formed by the overlapping of the substrate body 11 and the cover 2, is located on the outer surface of the cover A. At this time, the outer hinge portion 122 and the inner hinge portion 121 of the extension portion 12, which is continuously provided with the substrate body 11 of the retainer body JH and supported by the first and second binding feet G and H, are bent respectively. The longitudinal strip-shaped portion between the outer hinge portion 122 and the inner hinge portion 121 in the extension portion 12 covers the upper side of the first and second binding feet G and H, and the inner hinge portion 121 covers the outer side of the first and second bent portions c2 and d2 that are adjacent to the cover A.

[0068] In other words, by moving the retainer body JH toward the outer surface of the cover A, the extended mounting part 12 lifts the first and second binding pieces C and D in an inclined position relative to the cover A via the first and second binding feet G and H.

[0069] <Binding feet (first binding foot G, second binding foot H)>

[0070] The transparent pocket E and the retainer J are bound together by first and second binding feet G and H, which are binding members supported on the first and second binding pieces C and D. In this embodiment, the first and second binding feet G and H are each in the shape of a strip. The base ends of the first and second binding feet G and H are fused together to form a closed loop.

[0071] The welded end gt of the first binding foot G is disposed between the near-opposing surface c13 of the first binding sheet 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 near-opposing surface d13 of the second binding sheet body d1 and the inner surface of the rear cover a2.

[0072] <Transparent Pocket E>

[0073] The transparent pocket E includes: a pocket body e1, which can internally receive a document P through an opening e11; and a retaining end e2, which is provided along the left end of the pocket body e1 and is configured with a first binding leg insertion hole e21 and a second binding leg insertion hole e22 for insertion of first and second binding legs G and H. In this embodiment, the opening e11 is provided along the retaining end e2 in the pocket body e1.

[0074] The transparent pocket E can change its position in accordance with the position change of the cover A. In other words, the transparent pocket E is configured to bend and fold in half vertically at the center when the cover A is folded.

[0075] The held end e2 is a strip extending vertically. A pair of first binding foot insertion holes e21 are provided in the upper half of the held end e2 for the first binding foot G to be inserted. A pair of second binding foot insertion holes e22 are provided in the lower half of the held end e2 for the second binding foot H to be inserted.

[0076] The second binding foot insertion hole e22 is an elongated hole extending in the vertical direction, which enables the lower half of the transparent pocket E to move flexibly relative to the back cover a2 in the vertical direction when the cover A is folded in half.

[0077] <Retaining component J>

[0078] The retainer J, serving as a storage unit, is structured to easily clamp and hold the document P. The retainer J includes a base plate 1 and a cover plate 2. The retainer J forms a storage space sp between the base plate 1 and the cover plate 2, capable of accommodating the document P.

[0079] The retainer J, together with multiple transparent pockets E, is stacked on the inner surface of the cover A via first and second binding feet G and H, which are supported by first and second binding pieces C and D. Furthermore, the retainer J is positioned at the top (frontmost) in the unfolded position (T).

[0080] That is, the retainer J is located at the top (front) in the unfolded position (T) and can function as a cover replacement in the unfolded position (T) to cover multiple transparent pockets E from the top (front).

[0081] The retainer J comprises: a substrate 1, which is a first sheet having a first bent portion N extending in the left-right direction at the middle portion in the vertical direction; and a cover sheet 2, which is a second sheet overlapping the front side of the substrate 1 and having a second bent portion R extending in the left-right direction at the middle portion in the vertical direction corresponding to the first bent portion N.

[0082] The substrate 1 has a substrate body 11 that is longitudinally rectangular in unfolded position (T) and an extension part 12 that extends from the binding start side, i.e. the left end of the substrate body 11.

[0083] On substrate 1, a first bending portion N is provided at the center in the vertical direction in the unfolded posture (T). The first bending portion N has a central bending line n1 that extends in a straight line in the left-right direction, and vertical bending lines n2 that are disposed above and below the central bending line n1 and extend in a straight line in the left-right direction.

[0084] The first bending portion N is provided across the entire width between the left and right ends of the substrate 1. In other words, the first bending portion N is provided in the middle of each vertical direction in the substrate body 11 and the extension portion 12. In the substrate 1, the portion above the first bending portion N in the unfolded posture (T) is called the upper half 1a, and the portion below the first bending portion N is called the lower half 1b.

[0085] The first bend N is configured as follows: Figure 8 As shown, in the unfolded posture (T), the central broken line n1 and the left and right broken lines n2 are positioned on approximately the same horizontal line, forming a roughly flat posture. Figure 9 As shown, in the folded posture (F), the central fold line n1 is located on the outer side of the left and right fold lines n2, forming a valley fold.

[0086] The substrate body 11 and the cover plate 2 cooperate to form a retainer body JH with a storage space sp capable of accommodating a document P. The substrate body 11 has a first bent portion N between the upper half 111 and the lower half 112.

[0087] At the upper left corner of the substrate body 11, a retaining piece 113 is provided to hold the upper left corner portion, which serves as the free end of the cover piece 2. The retaining piece 113 is a sheet-like member integrally extended from the upper edge of the substrate body 11. After being folded back towards the front surface of the substrate body 11, its left end is fused to the left end of the substrate body 11. The cover piece 2 is continuously provided at the right and lower ends of the substrate body 11 by means of integral or fusion.

[0088] The extension section 12 includes: an inner hinge section 121, which is provided along the left end of the substrate body 11 and extends in the vertical direction; an outer hinge section 122, which is located outside the inner hinge section 121 and is arranged substantially parallel to the inner hinge section 121; a pair of upper and lower first binding foot insertion holes 13, which are binding foot insertion holes disposed in the upper half outside the outer hinge section 121; and a pair of upper and lower second binding foot insertion holes 14, which are binding foot insertion holes disposed in the lower half outside the outer hinge section.

[0089] Furthermore, the extension part 12 constitutes a retainer body support part that supports the retainer body JH, which is mainly composed of the substrate body 11 and the cover plate 2.

[0090] The upper part of the extension section 12 is provided with a pair of upper and lower first binding foot insertion holes 13 for the insertion of the first binding foot G. The lower part of the extension section 12 is provided with a pair of upper and lower second binding foot insertion holes 14 for the insertion of the second binding foot H. The second binding foot insertion holes 14 are elongated holes extending in the vertical direction, configured so that when the cover A is folded in half, the lower half of the retainer J can easily move relative to the rear cover a2 in the vertical direction.

[0091] The cover plate 2 is set to approximately the same size as the substrate body 11. The cover plate 2 can cover the substrate body 11 from the front. The right end and lower end of the cover plate 2 are integrally or welded to the substrate body 11.

[0092] The cover 2 includes: an upper half 21 in the shape of a horizontally elongated rectangle, a lower half 22 in the shape of a horizontally elongated rectangle, a second bend R disposed between the upper half 21 and the lower half 22, and a continuous notch 23 for preventing the right edge of the second bend R from being between the substrate body 11.

[0093] The second bending portion R is located at the center of the cover plate 2 in the vertical direction when it is in the unfolded posture (T). The second bending portion R has multiple fold lines, namely a central fold line r1 that extends in a straight line in the left-right direction and a vertical fold line r2 that is arranged above and below the central fold line r1 and extends in a straight line in the left-right direction.

[0094] like Figure 9 As shown, the second bend R is configured to bend away from the first bend N in the folding posture (F). More specifically, the second bend R is configured to have a mountain-shaped bend in the folding posture (F), with the central bend r1 located inside the left and right bends r2.

[0095] Furthermore, in this embodiment, the second bend R is not flat in the unfolded position (T), but rather has a gentler fold shape compared to the folded position (F). In other words, the second bend R also maintains a fold shape in the unfolded position (T) where the central fold line r1 is located inside the left and right fold lines r2.

[0096] The retainer J is configured such that the base sheet 1 and the cover sheet 2 can be folded (F) and unfolded (T) with the first and second bending portions N and R as rotation centers. That is, the retainer J can change its posture in accordance with the posture change of the cover A. In other words, the retainer J is configured such that when the cover A is folded in half, it can be folded in half at the first and second bending portions N and R located at the center in the vertical direction, following the cover A.

[0097] Furthermore, if component J remains in a folded position (F) while the orientation of cover A changes, such as Figure 9As shown, the central broken line n1 in the first bend N is significantly separated from the central broken line r1 in the second bend R. Furthermore, at this time, the upper and lower broken lines r2 in the second bend R can move towards each other.

[0098] Therefore, in the folding posture (F), a relatively large bending space sk can be ensured between the first bending portion N and the second bending portion R in the retainer J for accommodating the bent portion pe of the clamped document P. That is, in the folding posture (F), the retainer J can also form a flexible bending space sk between the first and second bending portions N and R that can accommodate the bent portion pe of the document P, thus appropriately accommodating a relatively large number of documents P.

[0099] As described above, the folder in this embodiment includes a cover A and a transparent pocket E, which is a storage member, and is bound to the cover A by first and second binding feet G and H, which are binding members.

[0100] Furthermore, the cover A is integrally provided with first and second binding pieces C and D that can be folded back as binding pieces, and the transparent pocket E is bound using first and second binding feet G and H supported by the first and second binding pieces C and D.

[0101] Therefore, if it is a folder of this embodiment, it has a structure in which the welded ends, which are part of the first and second binding feet G and H, are not easily exposed from the outer surface of the cover A.

[0102] The first and second binding pieces C and D are continuously arranged relative to the cover A via a first bending portion c2 and a second bending portion d2, and the portions other than the first and second bending portions c2 and d2 are not constrained relative to the cover A.

[0103] Therefore, the first and second binding pieces C and D are cantilevered on the cover A via the first and second bends c2 and d2, and thus can move flexibly in response to the movement of the transparent pocket E and the retainer J.

[0104] The cover A and the transparent pocket E are designed to be folded in one piece.

[0105] Therefore, the document P can be easily stored in the transparent pocket E, and the folder can be folded in half to make it compact enough for easy carrying.

[0106] Cover A has a front cover a1 and a rear cover a2 connected by a spine a3, which serves as a hinge. Cover A is configured to be able to be opened in an unfolded position (T) where the front cover a1 and the rear cover a2 are approximately coplanar, and to be closed in a position where the inner surfaces of the front cover a1 and the rear cover a2 face each other through a transparent pocket E. Furthermore, in the unfolded position (T), when opened with the retainer J positioned on the outer surface of cover A, the first and second binding pieces C and D are tilted relative to cover A.

[0107] Therefore, by tilting the first and second binding pieces C and D, the opening e11 of the transparent pocket E can be easily and smoothly accessed.

[0108] Cover A has a front cover a1 and a rear cover a2 connected by a spine a3, a first binding piece C is disposed on the front cover a1, and a second binding piece D is disposed on the rear cover a2.

[0109] Therefore, the first binding sheet C and the second binding sheet D are separated, which allows the cover A, the base sheet 1 and the retainer J to be properly folded in the middle in the vertical direction.

[0110] That is, since the first binding piece C and the second binding piece D are set separately from each other, they are less likely to interfere with each other due to changes in posture between unfolded posture (T) and folded posture (F).

[0111] It has first and second binding feet G and H in the shape of strips, and binding foot insertion holes c11 and d22 are provided on the first and second binding pieces C and D for the first and second binding feet G and H to be inserted. Therefore, multiple transparent pockets E and retaining members J can be properly supported on the cover A.

[0112] Furthermore, the present invention is not limited to the embodiments detailed above.

[0113] The binding component is not limited to the binding feet shown in the above embodiments; it can be any structure as long as it can bind the storage component or the storage body.

[0114] In addition, any storage component or storage body can be used to store documents, and is not limited to the transparent pockets and retainers shown in the above embodiments.

[0115] The binding sheet is not limited to having multiple binding sheets relative to the cover; for example, it can also have a single binding sheet relative to the cover.

[0116] Binding feet are not limited to strips; they can also be rope-like.

[0117] 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.
