An object of the present invention is to provide a file that can be used as a simple lectern and does not occupy a large space along the depth direction at that time.

The present invention includes a base provided with a holding portion for holding paper leaves, and a cover member attached to the back surface side of the base and folded so as to wrap around to the front surface side of the base. By refracting the part that is not attached to the back surface side and inserting a part of it between the cover member and the base to bring it into contact with the back surface of the base, a file that can support the base in an upright posture was constructed. ..

More specifically, the front cover member has a back cover attached to the back surface side of the base and a front cover that overlaps the front surface side of the base, and at least a part of the back cover is from the back surface of the base. The base can be supported in an upright posture by separating it and bringing at least a part of the front cover into contact with the back surface of the base.

The front cover is provided with a hinge that serves as a crease when the cover member is refracted, and when the base is supported in an upright posture, a part of the front cover that is refracted via the hinge is used as a base. The rest of the surface is used as the ground contact surface.

When the base is supported in an upright posture, if a restoring force that elastically presses the base toward the front surface side acts on a part of the cover member that comes into contact with the back surface of the base, that part is the base. It adheres to the back surface and does not easily come off, and can continue to support the base in a stable manner.

The base is, for example, an elastically deformable resin plate.

When the base is supported in an upright posture, the portion of the cover member attached to the back surface side of the base is offset upward from the middle of the upright posture of the base in the vertical direction, and the cover member has a portion. If the tip of a part of the base that comes into contact with the back surface of the base is inserted above the middle of the base in the upright posture in the vertical direction, the structure that supports the upright base becomes more stable.

According to the present invention, it can be used as a simple lectern, and at that time, it is possible to realize a file that does not occupy a large space along the depth direction.

An embodiment of the present invention will be described with reference to the drawings. 1 to 8 show the files of this embodiment. The file of the present embodiment can be used as a means for storing, holding, carrying, and transporting one or more documents and other paper sheets. Further, as shown in FIGS. 3 and 8, it can also be used as a simple lectern for reading the paper leaves in an upright state.

The files of the present embodiment include a front cover member 1 in which the front cover 11, spine cover 12, and back cover 13 are connected to each other, and a base (base sheet, base plate) 2 attached to the inner surface of the back cover 13 of the front cover member 1. , The base 2 is provided with holding portions 3, 41, and 42 for holding paper sheets. The cover member 1 also functions as a support that supports the base 2 in an upright standing posture.

The cover member 1 is, for example, a thin sheet made of a resin (thermoplastic resin such as PP (polypropylene)) whose outer surface exposed in a folded state is made of cloth 15 and whose inner surface is concealed inside is elastically deformable. As the number 16, the two are joined by sewing, welding, adhering, etc., and a paperboard (hard and thick paper, particularly a chip ball made from yellow paperboard or used paper as a raw material) is inserted between the two as a core material 19. It is inserted and reinforced. In the present embodiment, the cloth fabric 15 and the resin sheet 16 are sewn together. FIG. 6 shows the seam (stitch) 17.

A hinge 14 is provided between the front cover 11 and the spine 12, and between the spine 12 and the back cover 13, respectively. Further, hinges 14 are also provided in the intermediate portion of the front cover 11 and the intermediate portion of the back cover 13. In order to form these hinges 14, the resin sheet 16 on the inner surface side of the cover member 1 is provided with streaks (or ruled lines) by a thermal hinge streaking machine. The core material 19 is not a single plate, but is divided at a hinge 14.

The base 2 is, for example, a plate material made of an elastically deformable resin (PP or the like). The thickness and rigidity of the base 2 are larger than those of the resin sheet 16 on the inner surface side of the cover member 1, the pocket member 3 and the partition member 4 described later. In order to protect the holding portion and the paper leaves held by the holding portion, a protective portion 21 projecting downward is formed at the lower corner of the side end portion of the base 2. The base 2 is attached to the front cover member 1 by sewing, welding, adhesion, or the like so that the back surface thereof faces the inner surface of the back cover 13. In the present embodiment, the base 2 and the cover member 1 are sewn together. As shown in FIGS. 6 to 8, the stitched portion 18 corresponds to the hinge 14 at the intermediate portion of the back cover 13.

The holding portions 3, 41, and 42 are composed of a pocket member 3 and a partition member 4 attached to the base 2, and are pockets capable of holding paper sheets between the base 2 and the pocket member 3. The pocket member 3 is made of, for example, a thin sheet made of resin (PP or the like). The pocket member 3 is arranged on the surface side of the base 2 and faces the surface of the base 2. As shown in FIGS. 2, 3, 7, and 8, the pocket 3 is closed on one of its outer sides, that is, the right side and the lower side, and the other side, that is, the left side and the upper side are open. As shown in FIG. 4, the pocket member 3 has a joint piece 32 projecting to the right from its right end edge and a joint piece 33 projecting downward from its lower end edge. Then, these joining pieces 32 and 33 wrap around to the back surface side of the base 2 and are joined to the back surface of the base 2 by sewing, welding, adhesion or the like. In the present embodiment, the joining pieces 32 and 33 of the pocket member 3 are welded to the base 2.

The upper end edge 34 of the pocket 3 is inclined so as to gradually descend from the closed right side toward the open left side. Further, the left end edge 35 of the pocket 3 is retracted inward, that is, to the right of the left end edge of the base 2.

In addition, a gusset 31 is formed on the right side of the closed pocket 3. When a certain number or more of paper sheets are inserted and held in the pocket 3, the gusset 31 expands, the distance between the base 2 and the pocket member 3 widens, and the internal volume of the pocket 3 expands. .. The lower part of the 襠 31 is cut out so as to be recessed upward. Due to this notch 36, the lower end edge of the gusset 31 is retracted above the crease between the pocket member 3 and the joint piece 33, that is, the lower end edge of the pocket 3 itself and the lower end edge of the joint piece 32. The notch 36 is for releasing a force so that stress is not concentrated locally on the pocket 3.

Partitions 41 and 42 are provided between the surface of the base 2 and the pocket 3. The partitions 41 and 42 are composed of the partition member 4 shown in FIG. The partition member 4 is made of, for example, a thin sheet made of resin (PP or the like), and is folded in half along a crease to form two partitions 41 and 42 that are overlapped with each other. The crease of the partition member 4 is the lower end edge of each of the partitions 41 and 42. A 凵 -shaped notch is made in the central portion in the vicinity of the crease, and a joint piece 43 that protrudes downward when the partition member 4 is folded along the crease is formed. The joining piece 43 is joined to the pocket member 3 by sewing, welding, adhesion, or the like. In the present embodiment, the joining piece 43 of the partition member 4 is welded to the pocket member 3.

Tabs 411 and 421 protruding upward are formed on the upper end edges of the two partitions 41 and 42, respectively.

As shown in FIGS. 1 and 7, the file of the present embodiment can be folded and closed so that the front cover 11 faces the back cover 13, that is, it wraps around the front surface side of the base 2. In this state, the paper leaves held by the base 2, the pocket 3 which is the holding portion, the partitions 41, 42, and the holding portions 3, 41, 42 are covered with the cover member 1. Further, the flap 10 provided on the cover member 1 can be used to keep the cover member 1 in a closed state. A magnet (or a metal plate adhering to the magnet) 101 is embedded in the flap 10 in advance, and a metal plate (or magnet) 113 is embedded in the flap 10 in advance at a position facing the flap 10 on the front cover 11. The flap 10 is magnetically attached to the front cover 11.

As shown in FIGS. 3 and 8, in the file of the present embodiment, the base 2 provided with the holding portions 3, 41 and 42 is in an upright standing posture, and the paper leaves held by the holding portions 3, 41 and 42. It can also be used as a simple lectern for reading while standing upright. In order to use the file of the present embodiment as a lectern, the front cover member 1 of the file is unfolded, the back cover 13 is refracted via the hinge 14, and a part 131 thereof is separated from the back surface of the base 2. Since the other portion 132 of the back cover 13 is sewn and bound by the seams 17 and 18, it does not separate from the base 2.

Then, the spine cover 12 and the front cover 11 are refracted via the hinge 14, and a part 111 of the front cover 11 is inserted between the back cover 13 and the base 2 to be brought into contact with the back surface of the base 2. The other portion 112 of the front cover 11 that does not abut on the back surface of the base 2 serves as a base, that is, a ground plane.

When the base 2 is supported in an upright standing posture, the stitched portion 18 attached to the back surface side of the base 2 on the back cover 13 is biased upward from the vertical middle 6 of the upright base 2. Further, the tip of the portion 111 in contact with the back surface of the base 2 on the front cover 11 is inserted above the middle 6 in the vertical direction of the base 2 in the upright posture. In this state, the cover member 1 (particularly, the resin sheet 16 on the inner surface) abuts on the back surface of the base 2 on the front cover 11 due to the elastic force and the restoring force for returning from the bent state to the flat state. A restoring force 5 that presses the base 2 toward the surface side acts on the portion 111.

Incidentally, a metal plate (or a magnet) 133 is embedded in advance in a portion of the front cover 13 facing the flap 10, and the flap 10 is magnetized on the back cover 13 through the metal plate (or magnet) 133.

In the present embodiment, the base 2 provided with the holding portions 3, 41, and 42 for holding the paper leaves, and the cover member 1 attached to the back surface side of the base 2 and folded so as to wrap around the front surface side of the base 2. The portions 111, 112, 12, 131 which are provided and are not attached to the back surface side of the base 2 in the cover member 1 are refracted, and a part 111 thereof is inserted between the cover member 1 and the base 2 to form the base 2. By contacting the back surface of the base 2, a file that can support the base 2 in an upright posture was constructed. According to this embodiment, it can be used as a simple lectern, and in that case, the base 2 can be supported by using only a part 112 as a ground plane instead of the full width of the front cover 11, so that the base 2 can be supported on a desk or the like. It does not occupy a large space along the depth direction.

The front cover member 1 has a back cover 13 attached to the back surface side of the base 2 and a front cover 11 overlapping the front surface side of the base 2, and at least a part 131 of the back cover 13 is attached to the base 2. The base 2 can be supported in an upright posture by separating it from the back surface and bringing at least a part 111 of the front cover 11 into contact with the back surface of the base 2.

The front cover 11 is provided with a hinge 14 that serves as a crease when the cover member 1 is bent, and when the base 2 is supported in an upright posture, the front cover 11 is bent via the hinge 14. A portion 111 of the above is brought into contact with the back surface of the base 2, and the remaining portion 112 is used as a ground plane.

When the base 2 is supported in an upright posture, a restoring force 5 that elastically presses the base 2 toward the front surface side acts on a portion 111 of the cover member 1 that abuts on the back surface of the base 2. The portion 111 is in close contact with the back surface of the base 2 and does not easily slip out and fall down, so that the base 2 can be stably supported.

Since the base 2 is a thin plate body that can be elastically deformed, an operation of inserting or removing a part 111 of the front cover 11 between the back cover 13 and the base 2 when the base 2 is in an upright posture. Becomes simpler. In addition, due to the characteristics of the PP plate, a repulsive force is generated against elastic deformation, and it comes into close contact with the part 111 to which the front cover 11 is inserted, which makes it more difficult to pull out, and eventually the base 2 in the standing posture is less likely to fall down. ..

When the base 2 is supported in an upright posture, the portion 18 attached to the back surface side of the base 2 in the cover member 1 is biased upward from the middle 6 in the vertical direction of the base 2 in the upright posture. Since the tip of the portion 111 of the cover member 1 that abuts on the back surface of the base 2 is inserted above the middle 6 in the vertical direction of the base 2 in an upright posture, the cover member 1 (particularly, the front cover). The elastic return force of 11) makes it difficult for the base 2 to rotate so as to fall on its back, and the structure supporting the upright base 2 becomes more stable.

In addition, in the present embodiment, it is a file in which paper leaves can be posted in a standing posture, and one of both outer sides (right side) and the lower side are obstructed in the lower part in that posture, and the other side of both outer sides (left side). ) And a file provided with a pocket 3 open upward.

More specifically, it includes a base 2 provided with holding portions 3, 41, 42 for holding paper leaves, and a support (cover member) 1 capable of supporting the base 2 in an upright posture. One (right side) and the lower side of both outer sides of the base 2 in the standing posture are closed as the holding portions 3, 41, 42 on the surface side of the base 2 that is exposed when the base 2 is in the standing posture. The other side (left side) on both outer sides and the pocket 3 which is open upward are provided.

According to the present embodiment, it can be used as a simple lectern for reading the paper leaves in an upright state, and it is possible to provide a highly convenient file in which the paper leaves can be easily taken in and out at that time. Further, since the other side (left side) of the pocket 3 is open, even a paper leaf having a size protruding from the pocket 3 can be held and posted in the pocket 3.

A gusset 31 is formed at one end of both outer sides of the pocket 3 when the base 2 is in an upright posture, and it is possible to hold a certain number or more of paper leaves in the pocket 3. Become.

Since the upper end edge 34 of the pocket when the base 2 is in an upright posture is inclined so as to gradually descend from one of the two outer sides toward the other (left), the paper is relative to the pocket 3. It makes it easier to put in and take out leaves. In addition, due to such a shape, in the standing posture, the corner portion where the upper end edge 34 of the pocket member 3 and the other end edge 35 intersect does not hang down due to its own weight.

The other end edge (left end edge) 35 on both outer sides of the pocket 3 when the base 2 is in an upright posture is inward from the end edge on the same side (left side) of the file (base 2). Since it is retracted to (right side), the other end edge 35 of the pocket 3 which is the open end is protected by the file (base 2), and it is less painful.

Since the partitions 41 and 42 are provided in the pocket 3, that is, between the surface of the base 2 and the pocket 3, the partition 41 and 42 are provided between the pocket 3 and the partition 41, or between a plurality of partitions 41 and 42. Paper leaves can be separated and stored between the partition 42 and the base 2.

Since tabs 411 and 421 protruding upward are formed on the upper end edges of the partitions 41 and 42 when the base 2 is in an upright posture, the tabs 411 and 421 are hung with fingers to repeat the partitions 41 and 42. This makes it easy to put in and take out the paper leaves before and after the partitions 41 and 42.

The present invention is not limited to the embodiment described in detail above. For example, the holding portion to be provided on the base 2 is not limited to the pocket 3 and the partitions 41 and 42 as in the present embodiment, and the paper leaves are not dropped from the base 2 (particularly on the surface side of the base 2). Anything that can be retained may be used, such as a binding tool or a clipboard clip in various files.

Further, a gusset may be formed at the lower end portion of the pocket 3 when the base 2 is in an upright posture.

In addition, the specific configuration of each part can be variously modified without departing from the spirit of the present invention.
