[0046] Below, refer to Figures 1 to 12 An embodiment of the present invention will be described.

[0047] This embodiment is an embodiment in which the present invention is applied to a file folder capable of storing paper A.

[0048] The folder is configured to be able to change its posture so that it can be used as follows: Figure 1 As shown in FIG. 1 , the front cover 1 and the rear cover 2 can be opened in a substantially coplanar manner (M), as shown in FIG. Figure 3 As shown in FIG. 1 , the inner surfaces of the front cover 1 and the rear cover 2 can face each other in a closed position (T), and as shown in FIG. Figure 2 As shown, the outer surfaces of the front cover 1 and the rear cover 2 can face each other in the folding posture (R). In addition, the folding posture (R) is a posture in which either the front cover 1 or the rear cover 2 in the closed posture (T) is rotated 360° around the hinge H as the rotation center.

[0049] The file folder comprises: a front cover 1 and a back cover 2 as a second sheet connected via a hinge portion H; a first pocket sheet S1 as the first sheet, the first pocket sheet S1 being arranged on the inner surface side of the back cover 2 and being capable of cooperating with the back cover 2 to form a first pocket P1 as a pocket capable of accommodating paper A; a second pocket sheet S2, the second pocket sheet S2 being arranged on the inner surface side of the front cover 1 and being elongated in the left-right direction and being capable of cooperating with the front cover 1 to form a second pocket P2 as a pocket capable of accommodating paper A; a third pocket sheet S3, the third pocket sheet S3 being arranged on the inner surface side of the front cover 1 and being elongated in the up-down direction and being capable of cooperating with the front cover 1 to form a third pocket P3 as a pocket capable of accommodating paper A; a separation portion B, the separation portion B being arranged in a manner of connecting the first pocket sheet S1 and the second pocket sheet S2 and being always configured to be separated relative to the hinge portion H; and a rotatable binding tool G, the binding tool G being rotatably mounted on the end of the first pocket sheet S1.

[0050] The front cover 1 and the rear cover 2 are each in the shape of a longitudinally long rectangle. The edges of the four corners of the front cover 1 and the rear cover 2 are formed in a rounded manner. In the open posture (M), the front cover 1 is located on the left side and the rear cover 2 is located on the right side. The front cover 1 and the rear cover 2 are symmetrically centered on a hinge H extending in the vertical direction in the middle of the left-right direction. The front cover 1 and the rear cover 2 are integrally connected via the hinge H. Since the edges of the four corners of the front cover 1 and the rear cover 2 are formed in a rounded manner, wedge-shaped recessed areas are formed above and below the hinge H.

[0051] The hinge H is a member of a type called a resin hinge, and is provided between the inner edge of the front cover 1 and the inner edge of the rear cover 2. The hinge H extends in a straight line in the vertical direction. In this embodiment, auxiliary fold lines F are formed on the left and right sides of the hinge H, which are spaced apart by a predetermined interval and can expand the back width (Japanese: back width) in parallel with the hinge H.

[0052] Next, the first pocket sheet S1 which is the pocket sheet constituting the first pocket P1 provided on the rear cover 2 side will be described.

[0053] The first pocket sheet S1 is disposed at a position overlapping the back cover 2. The first pocket sheet S1 is connected to the back cover 2. The first pocket sheet S1 is connected to at least two sides of the back cover 2, so that the first pocket P1 capable of storing paper A is provided in the folder.

[0054] The first pocket sheet S1 is disposed on the inner surface side of the rear cover 2 , and the lower edge and the outer edge as one side edge are connected to the lower edge and the outer edge as one side edge of the rear cover 2 .

[0055] In this embodiment, since the first pocket piece S1 and the rear cover 2 are integrally formed of the same synthetic resin sheet, the lower edge of the first pocket piece S1 and the lower edge of the rear cover 2 are integrally and continuously provided via the fold line E. The outer edge of the first pocket piece S1 and the outer edge of the rear cover 2 are connected by welding.

[0056] The first pocket panel S1 includes a first pocket panel main body s11 having a substantially square shape, and an extended panel s12 having a vertically long rectangular shape extending from a part of the inner edge of the first pocket panel main body s11.

[0057] The first pocket sheet body s11 has a shaft hole ja formed near the upper end portion of the inner end edge, which is the other side end edge, for rotatably supporting the rotary binding tool G. A metal shaft member J is inserted into the shaft hole ja.

[0058] A shaft member insertion hole (not shown) into which the shaft member J is inserted is formed at the base end of the rotary binding tool G. The base end of the binding tool G is supported rotatably between the shaft member J and the first pocket sheet body s11.

[0059] The extension piece s12 is a protruding piece member supported in a cantilever manner relative to the first pocket piece body s11. The extension piece s12 is configured so that the base end portion can be bent. The extension piece s12 is a member whose base end portion is bent and can move in a manner overlapping the outer surface side of the first pocket piece body s11.

[0060] The extension piece s12 is pressed from the outside against the outer surface of the first pocket piece body s11 by the rotary binding tool G. That is, the paper A inserted between the extension piece s12 and the first pocket piece body s11 is clamped by the extension piece s12 pressed by the binding tool G and the first pocket piece body s11.

[0061] That is, the folder can not only accommodate paper A in the first pocket P1 arranged between the back cover 2 and the first pocket piece main body s11, but also can keep one or more papers A on the outer surface side of the first pocket piece main body s11 by utilizing the binding tool G arranged on the first pocket piece main body s11.

[0062] The area of ​​the first pocket sheet S1 is set smaller than that of the rear cover 2. More specifically, the height dimension of the first pocket sheet body s11 is set lower than that of the rear cover 2. The left-right dimension of the first pocket sheet body s11 is set shorter than that of the rear cover 2.

[0063] In this embodiment, the height of the first pocket sheet body s11 is set to a height at which the upper end of the B5 size paper (printing paper, etc.) stored in the first pocket P1 is exposed. That is, the height of the first pocket sheet body s11 is set to be shorter than the upper and lower dimensions of the B5 size paper.

[0064] The left-right dimensions of the first pocket sheet body s11 are as follows: Figure 4 As shown in the example of use, the length is set to a length such that the outer edge ae of the A4-size paper A held by the binding tool G can be located inside the outer edge of the rear cover 2 .

[0065] In this embodiment, the lateral width dimensions of the first pocket piece main body s11 and the rear cover 2 are set so that not only can the outer end edge ae of an A4-sized paper A held by the binding tool G be located closer to the inside than the outer end edge of the front cover 2, but also the outer end edge ae of the paper A held by the binding tool G is not too close to the inside to avoid getting fingers caught.

[0066] The file folder is formed with the first pocket sheet S1 and the back cover 2 having the above-described structure, and has a first pocket P1 capable of storing paper A. The first pocket P1 is open at the upper end and the inner end, and is closed at the lower end and the outer end.

[0067] The binding tool G is a member of a known structure called a “rotary binding tool” or a “sliding binding tool.” The binding tool G is made of a synthetic resin.

[0068] The binding tool G is rotatably mounted relative to the first pocket sheet body s11. The other pocket sheets, namely the second pocket sheet S2 and the third pocket sheet S3 disposed on the inner surface side of the front cover 1, are disposed at positions that do not interfere with the rotation end t1 of the binding tool G pivotally connected to the first pocket sheet body s11.

[0069] The binding tool G is a member having a roughly U-shaped cross-section and comprising a plate-like base g1 located on the back side of the first pocket sheet body s11, a plate-like pressing portion g2 located on the front side of the first pocket sheet body s11, and a connecting portion g3 connecting the base g1 and the pressing portion g2.

[0070] When the binding tool G is rotated relative to the first pocket piece body s11 so that the first pocket piece body s11 and the extension piece s12 are located between the base g1 and the pressing portion g2 of the binding tool G, the paper A arranged between the first pocket piece body s11 and the extension piece s12 is clamped by a certain clamping force.

[0071] Next, the second pocket sheet S2 constituting the second pocket P2 as a pocket provided on the front cover 1 side and the third pocket sheet S3 constituting the third pocket P3 as a pocket provided on the front cover 1 side will be described.

[0072] The second pocket piece S2 is in a horizontally long rectangular shape. The second pocket piece S2 is disposed on the inner surface side of the front cover 1 and the lower end edge and the outer end edge are connected to the lower end edge and the outer end edge of the front cover 1 by welding. The upper end side and the inner end side of the second pocket P2 formed by the second pocket piece S2 and the front cover 1 are open and the lower end side and the outer end side are closed.

[0073] The third pocket sheet S3 is in a vertically long rectangular shape. The third pocket sheet S3 is disposed on the inner surface side of the front cover 1 and only the upper portion of the outer edge is connected to the outer edge of the front cover 1 by welding. The lower portion of the third pocket sheet S3 is located between the front cover 1 and the second pocket sheet S2.

[0074] The third pocket P3 formed by the third pocket piece S3 and the front cover 1 is open at the upper end and the inner end, and closed at the outer end. The lower edge of the third pocket piece S3 is not joined to the front cover 1, but a portion where the lower edge of the second pocket P2 is joined to the lower edge of the front cover 1 is provided near the lower edge of the third pocket P3, so it is not substantially open.

[0075] Furthermore, in this embodiment, the L-shaped pocket PL capable of accommodating the paper A can be formed by the cooperation of both the second pocket sheet S2 and the third pocket sheet S3 and the front cover 1 .

[0076] That is, the L-shaped pocket PL comprises: a third pocket piece S3, which is arranged on the inner surface of the front cover 1 and is long in the vertical direction and whose outer edge is connected to the outer edge of the front cover 1; and a second pocket piece S2, which is separated from the third pocket piece S3 and arranged closer to the front side than the third pocket piece S3, that is, closer to the front side when viewed from the front in the open posture (M). In addition, the third pocket piece S3 and the second pocket piece S2 are arranged in a substantially L-shaped manner on the inner surface side of the front cover 1.

[0077] The L-shaped pocket PL can flexibly accommodate a relatively small paper C. For example, Figure 4 As shown, when storing paper C of a postcard size or a size smaller than the postcard size, the paper C can be properly stored and can be smoothly taken out when necessary by inserting the paper C between the second pocket piece S2 and the third pocket piece S3. Figure 4 In the figure, a sheet C indicated by a reference numeral C is smaller than the A4 size and the B5 size, and illustrates a color sheet (red sheet) made of synthetic resin for hiding characters used in learning.

[0078] In addition, if Figure 5 As shown, when accommodating A4-size or B5-size paper A, by inserting the paper A between the front cover 1 and the second pocket piece S2 and between the front cover 1 and the third pocket piece S3, the paper A can be properly accommodated and can be smoothly taken out when necessary.

[0079] Next, the separation portion B will be described.

[0080] The separation portion B is provided continuously with the first pocket piece S1 and the second pocket piece S2, and is disposed on the inner surface side of the front cover 1 and the rear cover 2, and can cooperate with each cover 1, 2 to form an intermediate pocket Pc as a pocket. The separation portion B is located at a position separated from the near front side of the hinge portion H when viewed from the front in the open posture (M), and is provided at a position separated from the hinge portion H in the folded posture (R). The separation portion B is formed as a portion connecting the inner end edge s1e of the first pocket piece S1 and the inner end edge s2e of the second pocket piece S2.

[0081] The separation portion B is shaped to protrude toward the front side in the open position (M). Figure 7 and Fig.10 As shown, the separation portion B is in a mountain-shaped protrusion toward the front side in the open posture (M). The separation portion B includes: a ridge portion b1, which is formed at a position substantially consistent with the hinge portion H in the open posture (M); a left side plate portion b2 in a rectangular plate shape, which is located on the left side of the ridge portion b1; and a right side plate portion b3 in a rectangular plate shape, which is located on the right side of the ridge portion b1.

[0082] The separation portion B is between the lower portion of the left edge of the first pocket piece S1 and the right edge of the second pocket piece S2. In other words, the left edge of the left side plate b2 is connected to the second pocket piece S2, and the right edge of the right side plate b3 is connected to the left edge of the first pocket piece S1.

[0083] The upper and lower ends of the separation portion B are open. That is, the separation portion B is supported in a cantilevered manner relative to the first and second pocket sheets S1 and S2, and can form a middle pocket Pc capable of accommodating paper sheets A in cooperation with the front cover 1 and the rear cover 2.

[0084] In this embodiment, the first pocket panel S1, the separation portion B, and the second pocket panel S2 are continuously provided integrally from the same sheet material.

[0085] In addition, if Fig.11 As shown in FIG. 1 , the front cover 1, the rear cover 2, the first pocket sheet S1, the separation portion B, and the second pocket sheet S2 are integrally formed of the same synthetic resin sheet. Fig.12 As shown, the third pocket sheet S3 is formed of a synthetic resin sheet separate from the sheet including the front cover 1 described above.

[0086] As described above, the file folder of this embodiment has a front cover 1 and a back cover 2 connected via a hinge portion H, and is constructed to be able to change postures so that the front cover 1 and the back cover 2 can be unfolded in a roughly coplanar manner (M), the front cover 1 and the back cover 2 can be in a closed posture (T) with the inner surfaces of the front cover 1 and the back cover 2 facing each other, and the front cover 1 and the back cover 2 can be in a folded posture (R) with the outer surfaces of the front cover 1 and the back cover 2 facing each other.

[0087] Furthermore, on the inner surfaces of the front cover 1 and the back cover 2, a first pocket sheet S1 and a second pocket sheet S2 are provided as pocket sheets that can cooperate with the front cover 1 and the back cover 2 to form a first pocket P1 and a second pocket P2 as pockets.

[0088] A separation portion B is provided, which is continuously provided with the first pocket piece S1 and the second pocket piece S2, and is located at a position separated from the near front side of the hinge portion H in the open posture (M), and is located at a position separated from the hinge portion (H) in the folded posture (R).

[0089] Therefore, it is possible to provide a file folder that can be in not only an open position (M) and a closed position (T) but also a folded position (R) in which the outer surfaces of the front cover 1 and the rear cover 2 face each other without any difficulty.

[0090] That is, since the first pocket piece S1 and the second pocket piece S2 are connected by the separation portion B, even if the front cover 1 and the rear cover 2 are rotated in the desired direction with the hinge portion H as the rotation center in order to adopt a folded posture (R), the rotation of the front cover 1 and the rear cover 2 will not be hindered by the separation portion B and can be moved to the predetermined position without force.

[0091] In other words, in the case of the file folder shown in this embodiment, the folded-back posture (R) can be adopted even when the pocket such as the one straddling the front cover 1 and the rear cover 2 is located on the inner surface side of the front cover 1 and the rear cover 2. Therefore, the user who uses the file folder can select the folded-back posture (R) as a change in the usage mode, and can obtain a comfortable feeling of use and excellent convenience.

[0092] A hinge portion H is provided between the front cover 1 and the rear cover 2 of substantially the same size. The other of the front cover 1 and the rear cover 2 is configured to be bent 360° around the hinge portion H.

[0093] Therefore, it is possible to provide a file folder having an excellent appearance in which the edges of the front cover 1 and the rear cover 2 are easily and neatly aligned in the opened posture (M) and the folded posture (R).

[0094] It comprises: a first pocket piece S1, which is arranged on the inner surface of the rear cover 2 and has its lower edge and outer edge connected to the lower edge and outer edge of the rear cover 2; a second pocket piece S2, which is arranged on the inner surface of the front cover 1 and has its lower edge and outer edge connected to the lower edge and outer edge of the front cover 1; and a separation portion B, which connects the inner edge s1e of the first pocket piece S1 with the inner edge s2e of the second pocket piece S2.

[0095] Therefore, the file folder can take the folded position (R) even though it has the pockets (the first pocket P1 , the middle pocket Pc, and the second pocket P2 ) spanning the front cover 1 and the back cover 2 .

[0096] The separation portion B has a shape that protrudes toward the front side in the open position (M).

[0097] Therefore, the protruding shape of the separation portion B can be used to appropriately separate the paper A placed on the outer surface of the second and third pocket pieces S2 and S3 on the front cover 1 side from the paper A placed on the outer surface of the first pocket piece S1 on the back cover 2 side.

[0098] It comprises: a third pocket piece S3, which is arranged on the inner surface of the front cover 1 and is long in the up and down direction and the outer end edge is connected to the outer end edge of the front cover; and a second pocket piece S2, which is separate from the third pocket piece S3 and is arranged closer to the front side than the third pocket piece S3, that is, closer to the front side when viewed from the front in the open posture (M), and the third pocket piece S3 and the second pocket piece S2 are arranged in a roughly L shape on the inner surface side of the front cover 1.

[0099] Therefore, the second pocket piece S2 and the third pocket piece S3 are arranged in an L-shape on the front cover 1 side, so that different sizes of paper (paper A, paper C, etc.) can be appropriately selected in consideration of ease of taking out and difficulty of falling.

[0100] The first pocket panel S1, the separation portion B, and the second pocket panel S2 are continuously provided integrally from the same sheet material.

[0101] Therefore, the manufacturing is easy and the connection strength is excellent.

[0102] In addition, the present invention is not limited to the embodiments described in detail above.

[0103] The paper to be stored or held in the folder is not limited to paper, but may be made of synthetic resin, wood, or metal. That is, any paper may be used as long as it is a sheet.

[0104] The binding tool is not limited to the rotary binding tool, and various binding tools can be applied.

[0105] For example, Fig.13 As shown in (a) of FIG. 1 , the file folder may be a binding tool D of a binding string type composed of a binding string d1 and a binding member d2 that can be engaged with and disengaged from the binding string d1 .

[0106] For example, Fig.13 As shown in (b) of FIG. 1 , the file folder may be a binding tool K composed of a base plate k1 and a pressing frame member k2 pivotally supported on the base plate k1 and biased toward the base plate k1 by a spring (not shown).

[0107] The position where the binding tool is provided is not limited to the vicinity of the inner edge of the first pocket panel as in the above-mentioned embodiment.

[0108] For example, Fig.14 As shown in (a) of FIG. 1 , the file folder may be provided with a binding tool G near the upper edge of the first pocket piece S1 as a pocket piece.

[0109] For example, Fig.14 As shown in (b) of the document, the file folder may be provided with a binding tool G near the outer edge of the first pocket piece S1 as a pocket piece.

[0110] Of course, various changes can be made to the specific forms of the front cover and the rear cover without departing from the gist of the present invention.

[0111] For example, Fig.15 As shown, the front cover 1 can also be provided with a connecting hole I for inserting the binding tool G provided on the rear cover 2 side in the closed posture (T). If such a structure is provided, in the closed posture (T), the increase in the thickness dimension of the entire folder caused by the presence of the binding tool G can be appropriately suppressed.

[0112] The binding tool can also use the upper end side as a rotating end and pivotally connect the lower end side relative to the first pocket piece.

[0113] The specific shape of the separation portion is not limited to the shape shown in the above embodiment, and can be set to various shapes.

[0114] For example, regarding the separation portion B, it can be Fig.16 As shown in (a) of FIG. 1 , a mountain-shaped member having a flat top formed flat on the top may also be formed as shown in FIG. Fig.16 As shown in (b) of FIG. 1 , a plurality of fold lines b5 are provided at regular intervals and can be formed into a smooth mountain-shaped member. Fig.16 As shown in (c), a member having a smooth mountain shape can be formed by utilizing the flexible deformation of the member without providing a folding line.

[0115] The pocket is not limited to the one formed by cooperation between the pocket sheet and the front cover and the rear cover, and the pocket may be formed without including the front cover and the rear cover.

[0116] The pocket may be provided with a mat.

[0117] The pocket piece capable of forming a pocket in cooperation with the cover may be provided on the inner surface of at least one of the front cover and the rear cover.

[0118] Separation portion is not limited to be continuously arranged integrally with the pocket piece. That is, separation portion can also be constituted with the pocket piece in a separate body, and is continuously arranged with the pocket piece by being joined when manufacturing.

[0119] The pocket piece may not be provided with a binding tool.

[0120] The specific shape of the first, second and third pocket pieces can be set to an appropriate shape. In other words, the first, second and third pocket pieces are not limited to rectangular shapes, and may have inclined edges or curved edges in a part.

[0121] The connection position of pocket piece and cover can be only one side, also can be two sides, also can be three sides.In addition, as long as the connection position can form a pocket between pocket piece and cover, various settings can be carried out.

[0122] The pocket is not limited to the one provided on the inner surface side of both the front cover and the rear cover, and any pocket may be provided on the inner surface of at least one of the front cover and the rear cover.

[0123] The pocket may be closed at only one end, or at three directions: one end and both ends.

[0124] The folder can also be provided with a backspin (Japanese: back sheet) between the front cover and the back cover. In this case, a hinge is formed between the backspin and the front cover, and between the backspin and the back cover.

[0125] The opening posture of the front cover and the back cover is not limited to the posture of being completely opened in the same plane. In other words, the opening posture means a state including a state in which a convex and concave shape is caused by folds of the components.

[0126] In the above-described embodiment, A4-size paper is shown as an example of the document stored in the pocket, but paper of a size different from A4 size (for example, A3 size, B5 size, etc.) may be used as a matter of course.
