[0010] Problems to be Solved by the Invention

[0011] A desirable object of the present invention is to provide a folder that can be used as a simple reading stand without occupying a large space in the depth direction when used as such.

[0012] Means for Solving the Problems

[0013] In this invention, a folder is constructed comprising: a base having a holding portion for holding paper; and a cover member mounted on the back side of the base and folded around the surface side of the base. By bending a portion of the cover member not mounted on the back side of the base and inserting a portion therein between the cover member and the base to abut against the back side of the base, the base can be supported in an upright position.

[0014] More specifically, the cover member has a rear cover mounted on the back side of the base and a front cover overlapping the surface side of the base, such that at least a portion of the rear cover is separated from the back side of the base and at least a portion of the front cover abuts against the back side of the base, thereby enabling the base to be supported in an upright position.

[0015] The front cover is provided with a hinge that forms a crease when the cover member is bent. When the base is supported in an upright position, a portion of the front cover bent through the hinge abuts against the back of the base, while the remaining portion serves as the contact surface.

[0016] If, when the base is supported in an upright position, a portion of the cover member that abuts against the back of the base has a restoring force that presses the base toward the surface side through elasticity, then that portion is tightly attached to the back of the base and is not easily pulled out, thus stably and continuously supporting the base.

[0017] The base is, for example, a resin plate capable of elastic deformation.

[0018] If, when the base is supported in an upright position, the portion of the cover member mounted on the back side of the base is positioned slightly above the midpoint of the base in the vertical direction in the upright position, and the tip of the portion of the cover member that abuts against the back side of the base is inserted slightly above the midpoint of the base in the vertical direction in the upright position, then the structure supporting the upright base is more stable.

[0045] One embodiment of the present invention will be described with reference to the accompanying drawings. Figures 1 to 8 The folder of this embodiment is shown. The folder of this embodiment can be used as a means of storing and holding one or more documents and other paper items for carrying and transporting. Furthermore, as... Figure 3 and Figure 8 As shown, it can also be used as a simple reading stand for reading paper items in an upright position.

[0046] The folder in this embodiment includes: a cover member 1, which is formed by connecting a front cover 11, a spine 12, and a rear cover 13; a base (substrate, substrate) 2, which is mounted on the inner surface of the rear cover 13 of the cover member 1; and retaining portions 3, 41, and 42, which are provided on the base 2 and used to retain paper. The cover member 1 also functions as a support for supporting the base 2 in an upright position.

[0047] The cover component 1 is, for example, a component in which the outer surface exposed when the cover component 1 is folded is a fabric 15, and the inner surface concealed on the inside is a thin sheet 16 made of a thermoplastic resin (PP (polypropylene) or other thermoplastic resin) that can be elastically deformed. The two are joined together by sewing, welding, or bonding, and a cardboard (a hard, thick paper, especially coarse cardboard made from yellow cardboard or waste paper) is inserted between them as a core material 19 for reinforcement. In this embodiment, the fabric 15 and the resin sheet 16 are sewn together. Figure 6 The stitches (threads) are shown in Figure 17.

[0048] Hinges 14 are provided between the front cover 11 and the spine 12, and between the spine 12 and the rear cover 13. Furthermore, hinges 14 are also provided at the middle of the front cover 11 and the middle of the rear cover 13. To form these hinges 14, stripes (or grid lines) formed by a heat-jointing stripe machine are attached to the resin sheet 16 on the inner surface of the cover member 1. The core material 19 is not a single sheet, but is broken at the hinges 14.

[0049] The base 2 is, for example, a sheet made of resin (PP, etc.) that can be elastically deformed. The thickness and rigidity of the base 2 are greater than those of the resin sheet 16 on the inner surface of the cover member 1, the pocket member 3 (described later), and the divider member 4. To protect the holding part and the paper held therein, a downwardly extending protective part 21 is formed at the lower corner of the side end of the base 2. The base 2 is attached to the cover member 1 by sewing, welding, or bonding, with its back facing the inner surface of the rear cover 13. In this embodiment, the base 2 is sewn to the cover member 1. Figures 6 to 8 As shown, the sewn part 18 corresponds to the hinge 14 in the middle part of the back cover 13.

[0050] The retaining parts 3, 41, and 42 are composed of a pocket member 3 and a separating member 4 installed on the base 2, and are capable of holding paper-like items between the base 2 and the pocket member 3. The pocket member 3 is made of, for example, a thin sheet of resin (PP, etc.). The pocket member 3 is disposed on the surface side of the base 2, opposite to the surface of the base 2. Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, pocket 3 is closed on one of its two outer sides (right and bottom) and open on the other two outer sides (left and top). Figure 4 As shown, the pocket member 3 has a connecting piece 32 extending to the right from its right end edge and a connecting piece 33 extending downward from its lower end edge. Furthermore, these connecting pieces 32 and 33 wrap around to the back side of the base 2 and are joined to the back side of the base 2 by stitching, welding, or bonding. In this embodiment, the connecting pieces 32 and 33 of the pocket member 3 are welded to the base 2.

[0051] The upper edge 34 of pocket 3 slopes downwards as it moves from the closed right side to the open left side. In addition, the left edge 35 of pocket 3 is recessed inwards to the right than the left edge of base 2.

[0052] Furthermore, a joint 31 is formed on the right side of the closed pocket 3. When a certain number of sheets of paper are inserted into the pocket 3 and held therein, the joint 31 expands, the gap between the base 2 and the pocket member 3 widens, and the internal volume of the pocket 3 increases. A notch 36 is cut into the lower part of the joint 31 in an upwardly recessed manner. Through this notch 36, the lower edge of the joint 31 is recessed upwards from the crease between the pocket member 3 and the connecting piece 33, i.e., the lower edge of the pocket 3 itself and the lower edge of the connecting piece 32. The notch 36 is used to release force in a way that prevents stress from concentrating locally in the pocket 3.

[0053] Dividers 41 and 42 are provided between the surface of the base 2 and the pocket 3. Dividers 41 and 42 are made of... Figure 5The shown divider member 4 is constructed. The divider member 4 is made of a thin sheet of resin (PP, etc.), which is folded along a crease to form two overlapping dividers 41 and 42. The crease of the divider member 4 forms the lower edge of each divider 41 and 42. A U-shaped slit is formed in the center near the crease, and after folding the divider member 4 along the crease, a downwardly protruding connecting piece 43 is formed. This connecting piece 43 is joined to the pocket member 3 by sewing, welding, or gluing. In this embodiment, the connecting piece 43 of the divider member 4 is welded to the pocket member 3.

[0054] An upwardly protruding tab 411 and 421 are formed on the upper edge of each of the two separators 41 and 42.

[0055] like Figure 1 and Figure 7 As shown, the folder of this embodiment can be folded and closed with its front cover 11 facing the rear cover 13, that is, with its front cover 1 wrapped around the surface of the base 2. In this state, the base 2, the pocket 3 serving as a holding part, the dividers 41, 42, and the paper held in the holding parts 3, 41, 42 are covered by the cover member 1. In addition, the cover member 1 can be kept closed by using the flaps 10 provided on the cover member 1. A magnet (or a metal plate attracted to a magnet) 101 is pre-embedded in the flap 10, and a metal plate (or magnet) 113 is pre-embedded in the front cover 11 at the part facing the flap 10, and the flap 10 is magnetically attracted to the front cover 11 through them.

[0056] like Figure 3 and Figure 8 As shown, the folder of this embodiment can also be used as a simple reading stand for reading while the base 2, which has holding parts 3, 41, and 42, is in an upright position and for reading while the paper held in the holding parts 3, 41, and 42 is upright. To use the folder of this embodiment as a reading stand, the cover member 1 of the folder is unfolded, and the rear cover 13 is bent via the hinge 14, so that a portion 131 separates from the back of the base 2. Since the other portion 132 of the rear cover 13 is sewn and glued by seams 17 and 18, it will not separate from the base 2.

[0057] Then, the spine 12 and the front cover 11 are bent via the hinge 14, and a portion 111 of the front cover 11 is inserted between the rear cover 13 and the base 2, abutting against the back of the base 2. The remaining portion 112 of the front cover 11 that does not abut against the back of the base 2 becomes the base, i.e., the ground.

[0058] When the base 2 is supported in an upright position, the sewn portion 18 of the rear cover 13, which is attached to the back side of the base 2, is positioned slightly above the center 6 in the vertical direction of the upright base 2. Furthermore, the tip of the portion 111 of the front cover 11 that abuts against the back side of the base 2 is inserted slightly above the center 6 in the vertical direction of the upright base 2. In this state, the elastic force and restoring force exerted by the cover member 1 (particularly the resin sheet 16 on the inner surface) to restore the base 2 from a bent state to a flat state, along with the restoring force 5 acting on the portion 111 of the front cover 11 that abuts against the back side of the base 2, presses the base 2 towards the surface.

[0059] Incidentally, a metal plate (or magnet) 133 is pre-embedded in the front cover 13 at the part facing the wing 10, through which the wing 10 is magnetically attracted to the rear cover 13.

[0060] In this embodiment, a folder is constructed comprising: a base 2 having holding portions 3, 41, and 42 for holding paper; and a cover member 1, which is mounted on the back side of the base 2 and folded around to the front side of the base 2. By bending the portions 111, 112, 12, and 131 of the cover member 1 that are not mounted on the back side of the base 2, and inserting a portion 111 between the cover member 1 and the base 2 to abut against the back side of the base 2, the base 2 can be supported in an upright position. According to this embodiment, it can be used as a simple reading stand, and at this time, only a portion 112 of the front cover 11 is used as the contact surface to support the base 2, rather than the entire width of the front cover 11, so that it does not occupy a large space along the depth direction on a table or the like.

[0061] The cover member 1 has a rear cover 13 mounted on the back side of the base 2 and a front cover 11 overlapping the surface side of the base 2, such that at least a portion 131 of the rear cover 13 is separated from the back side of the base 2 and at least a portion 111 of the front cover 11 abuts against the back side of the base 2, thereby enabling the base 2 to be supported in an upright position.

[0062] The front cover 11 is provided with a hinge 14 that forms a crease when the cover member 1 is bent. When the base 2 is supported in an upright position, a portion 111 of the front cover 11 bent through the hinge 14 abuts against the back of the base 2, and the remaining portion 112 serves as the contact surface.

[0063] When the base 2 is supported in an upright position, a portion 111 in the cover member 1 that abuts against the back of the base 2 is subjected to a restoring force 5 that presses the base 2 toward the surface side through elasticity. Therefore, this portion 111 is in close contact with the back of the base 2, and will not be easily pulled out or fall over, thus stably and continuously supporting the base 2.

[0064] Since the base 2 is a thin plate capable of elastic deformation, it is easier to insert or remove a portion 111 of the front cover 11 relative to the rear cover 13 and the base 2 when the base 2 is in an upright position. Furthermore, due to the properties of the PP board, it exhibits a rebound force relative to elastic deformation, adhering tightly to the inserted portion 111 of the front cover 11, making it more difficult to remove, and thus the upright base 2 is less likely to fall over.

[0065] When the base 2 is supported in an upright position, the portion 18 of the cover member 1 installed on the back side of the base 2 is positioned slightly above the middle 6 in the vertical direction of the base 2 in the upright position. The top end of the portion 111 of the cover member 1 that abuts against the back side of the base 2 is inserted slightly above the middle 6 in the vertical direction of the base 2 in the upright position. Therefore, the base 2 is less likely to rotate in a supine position due to the elastic restoring force of the cover member 1 (especially the front cover 11), and the structure supporting the upright base 2 is more stable.

[0066] Furthermore, in this embodiment, the folder is configured to be a type of folder that can display notices in a standing position. In this position, a pocket 3 is provided at the bottom part that closes one of the two outer sides (right side) and the bottom, and opens to the other of the two outer sides (left side) and the top.

[0067] More specifically, it includes: a base 2, which has holding parts 3, 41, and 42 for holding paper; and a support (cover member) 1, which can support the base 2 in an upright position. On the surface side of the base 2 exposed when the base 2 is in the upright position, there are pockets 3 as the holding parts 3, 41, and 42 that close one side (right side) and below of the upright base 2 and open to the other side (left side) and above.

[0068] According to this embodiment, a convenient reading holder that can be used for reading with paper items upright, and a folder that is easy to access and store paper items, can be provided. In addition, by leaving the other side (left side) of the pocket 3 open, even paper items that extend out of the pocket 3 can be kept in the pocket 3 for posting notices.

[0069] A gusset 31 is formed at one end of the two outer sides of the pocket 3 when the base portion 2 is in an upright posture, so that the pocket 3 can hold a certain number or more of paper sheets or the like.

[0070] The upper end edge 34 of the pocket when the base portion 2 is in the upright posture is inclined so as to gradually descend from one of the two outer sides toward the other (left side), thereby making it easier to take in and out paper sheets or the like relative to the pocket 3. In addition, by forming such a shape, the corner portion where the upper end edge 34 of the pocket member 3 intersects with the other side end edge 35 in the upright posture will not sag due to its own weight.

[0071] The other end edge (left end edge) 35 of the two outer sides of the pocket 3 when the base portion 2 is in the upright posture is retracted inward (to the right) relative to the end edge on the same side (left side) of (the base portion 2 of) the file, so that the other end edge 35 of the pocket 3 serving as the open end is protected by (the base portion 2 of) the file and is less likely to be damaged.

[0072] Since the partitions 41 and 42 are provided inside the pocket 3, that is, between the surface of the base portion 2 and the pocket 3, papers can be stored in a classified manner between the pocket 3 and the partition 41, between the plurality of partitions 41 and 42, or between the partition 42 and the base portion 2.

[0073] Since protruding pieces 411 and 421 protruding upward are formed at the upper end edges of the partitions 41 and 42 when the base portion 2 is in the upright posture, it is possible to place a finger on the protruding pieces 411 and 421 to flip the partitions 41 and 42, making it easy to take in and out the paper sheets or the like located in front of and behind the partitions 41 and 42.

[0074] In addition, the present invention is not limited to the embodiments described in detail above. For example, the holding portion to be provided on the base portion 2 is not limited to the pocket 3 and the partitions 41 and 42 as in the present embodiment, and may be members such as binding tools for various files or clips of a clipboard, as long as they can hold paper sheets or the like in a manner that they do not fall off from the base portion 2 (particularly, hold them on the surface side of the base portion 2).

[0075] In addition, a gusset may be formed at the lower end portion of the pocket 3 when the base portion 2 is in the upright posture.

[0076] Furthermore, the specific structure of each part can be variously modified within the scope not departing from the gist of the present invention.
