The present invention relates to a file (or binder) having a binder for binding paper sheets.

Files that can bind paper sheets such as paper documents, loose-leaf that is the inner paper of notebooks, resin clear book refills (so-called clear pockets and clear holders) are well known (for example, the following patent document ). This type of file generally consists of a front cover, a back cover and a back cover, and a binder for binding paper sheets.

When storing files, it is common to store them in a bookshelf or the like in an upright posture, that is, in a posture in which the front cover, back cover and back cover of the cover body are upright. At this time, the bound paper sheets hang down due to their own weight, and the lower edge of the paper sheets may protrude below the lower edge of the cover. If so, the lower edges of the paper sheets may come into contact with shelf boards or other objects during storage, loading, unloading, or carrying of files, and the paper sheets may be bent or rubbed and damaged.

If the size of the cover is much larger than the size of the paper sheets to be bound, even if the paper sheets sag under their own weight, they will not protrude from the cover. However, this is equivalent to enlarging the external size of the file, which occupies a large storage space during storage.

In addition, the front cover and the back cover can basically be freely rotated relative to each other. Therefore, there is a possibility that these may be opened unexpectedly when the file is put in, taken out or carried, and together with the bound paper sheets hanging down, there is a concern that handling of the file is hindered.

JP 2014-223782 A

An object of the present invention is to appropriately prevent paper sheets bound in a file from protruding from the cover and unintentionally opening the cover.

In the present invention, a front cover and a back cover that are relatively rotatable and openable, a binder that binds paper sheets between the front cover and the back cover that face each other when closed, and the front cover. provided along the lower edge of one of the back cover and the back cover and stands up toward the other to prevent the lower edge of the paper sheets bound by the binding tool from protruding from the lower edges of the front cover and the back cover and a guard supported by said one of said front cover and said back cover, and the other side of said guard standing from one to the other so as to straddle the lower edge and outer edge of the other closed cover. The file is constructed with bands that engage the edges to restrain the front and back covers from opening.

The guard includes a lower wall extending along the lower edge of one of the front cover and the back cover, and an outer wall extending along the outer edge of the one and connecting to the lower wall. If the lower wall and the outer wall are integrated so as to form a substantially L shape , the guard can be provided with necessary and sufficient strength and rigidity.

If at least a portion of the guard tilts upward when engaged with the band, sagging of bound sheets and unintentional opening of closed covers can be more effectively prevented.

The guard is formed, for example, by folding a piece protruding from one of the front cover and the back cover.

Further, a concave portion capable of engaging the band is formed in the edge of the other side of the guard that stands up from the one of the front cover and the back cover toward the other. is preferred.

According to the present invention, it is possible to appropriately prevent paper sheets bound in a file from hanging down due to their own weight and protruding from the cover, and from unintentionally opening the cover.

One embodiment of the present invention will be described with reference to the drawings. The file 1 of the present embodiment shown in FIGS. 1 to 11 is for binding paper sheets 4 to a cover body 2 in which a front cover 21, a back cover 22 and a back cover 23 are arranged side by side, similarly to known files. It is configured by attaching a binding tool 3 .

The cover body 2 is a thin plate made of hard resin such as polypropylene. Hinges 24 are interposed between the front cover 21 and the back cover 22 and between the back cover 22 and the back cover 23, respectively. The hinge 24 is, for example, a concave groove that extends in the cover height direction and makes the relevant portion thinner than other portions of the cover body 2 . The front cover 21 can rotate about the hinge 24 and the axis extending in the cover height direction with respect to the back cover 22 and the back cover 23 . In addition, the back cover 23 can rotate around the hinge 24 with respect to the back cover 22 and the front cover 21 around an axis extending in the cover height direction. As a result, the front cover 21 and the back cover 23 rotate relative to each other, and the cover body 2 can be opened and closed.

The binding device 3 has a plurality of binding rods 31, and by inserting the binding rods 31 into binding holes 41 penetrating the paper sheets 4 pre-punched in the paper sheets 4, a plurality of paper sheets are bound. 4, particularly a ring binding device in which an annular binding rod 31 opens and closes. The binding tool 3 is fixed to the back surface of the back cover 22 of the cover body 2, in other words, the inner surface facing the paper sheets 4 to be bound.

The specific structure of the binder 3 is not uniquely limited, and various known modes may be adopted as long as they can bind a plurality of paper sheets 4 . Depending on the mode of the binding device 3, it may be arranged on the inner side of the back cover 23, that is, on the edge of the side near the spine 22. FIG.

Thus, in the file 1 of this embodiment, the guard 25 and the band 26 are provided at the lower and outer corners of the back cover 23 , that is, the corners farther from the back cover 22 and binding device 3 .

The guard 25 allows the paper sheets 4 to hang down under its own weight when the file 1 in which the paper sheets 4 are bound is set up, that is, when the front cover 21, the back cover 22 and the back cover 23 of the cover body 2 are set upright. It functions to prevent the lower edge from protruding from the lower edges of the covers 21 and 23 and the outer edge of the paper sheet 4 from protruding from the outer edges of the covers 21 and 23. - 特許庁The guard 25 has a lower wall 251 extending in the cover width direction along the lower edge of the back cover 23 and an outer wall 252 extending in the cover height direction along the outer edge of the back cover 23, These lower wall 251 and outer wall 252 stand up toward the front cover 21 perpendicularly or substantially perpendicularly to the back cover 23 . The lower wall 251 and the outer wall 252 of the guard 25 are connected to each other at the lower and outer corners of the back cover 23 .

A guard 25 is formed integrally with the cover body 2 and the back cover 23. - 特許庁Specifically, as shown in FIG. 10, a piece 251 projecting downward from the lower edge of the back cover 23 and a piece 252 projecting outward from the outer edge of the back cover 23 are attached to the back cover. The cover 23 is continuously cut out. Then, the former piece that will be the lower wall 251 is bent upward with respect to the back cover 23, and the latter piece that will be the outer wall 252 is bent inward toward the back cover 22 with respect to the back cover 23. By doing so, a guard 25 standing from the back cover 23 is formed.

As shown in FIG. 10 , the outer edge 254 of the piece that forms the lower wall 251 extends outward beyond the outer edge of the back cover 23 . This outer end portion 254 serves as a joint allowance for connecting the lower wall 251 to the outer wall 252 . That is, both the pieces 251 and 252 are bent, the outer end 254 of the piece forming the lower wall 251 is overlapped with the inner surface or the outer surface of the piece forming the outer wall 252 , and the outer end 254 is attached to the piece 252 . The lower wall 251 and the outer wall 252 are connected by bonding, welding, or the like. In addition, the lower end portion of the piece forming the outer wall 252 may be extended downward from the lower edge of the back cover 23, and the lower end portion may be used as a joining margin for bonding or welding to the piece forming the lower wall 251. . The lower wall 251 and the outer wall 252 which are connected to each other form an integral guard 25 which is substantially L-shaped when viewed from the normal direction of the back surface of the back cover 23, in other words, the inner surface facing the sheets 4 to be bound. becomes.

As shown in FIGS. 7 and 8, the dimension D of the guard 25 (lower wall 251 and outer wall 252) erected from the back cover 23 toward the front cover 21 along the erecting direction is It is smaller than the width T and slightly more than half the back width T.

A concave portion 253 is formed at the edge of the lower wall 251 and the outer wall 252 of the guard 25 standing from the back cover 23 on the side facing the front cover 21 by notching a part thereof. The recessed portion 253 functions as an engaging portion for latching the band 26 .

The band 26 is a long elastic band such as a rubber band used to keep the cover body 2 closed so that the front cover 21 and the back cover 23 face each other. It is a string or strip.

One end of the band 26 is attached near the lower edge of the back cover 23, more specifically at a point slightly inwardly offset from the inner edge of the lower wall 251 of the guard 25. As shown in FIG. The other end of band 26 is also attached near the outer edge of back cover 23 , more specifically at a point slightly above the upper edge of outer wall 252 of guard 25 . In this embodiment, as shown in FIG. 9, mounting holes 231 are formed through the back cover 23 at the two locations on the back cover 23 . At the same time, on each end of the band 26, a retaining tool 261 made of metal or hard resin and extending in a direction crossing or perpendicular to the extending direction of the band 26 is fixed. Although the retainer 261 itself has high rigidity and is difficult to deform, the band 26 is easily deformed by bending. The rod-shaped retainer 261 and the end of the band 26 can be substantially aligned. Then, the ends of the retainer 261 and the band 26 are inserted into the mounting holes 231 from the surface side of the back cover 23, that is, from the outer surface side opposite to the back surface (inner surface) facing the paper sheet 4. By doing so, the band 26 is attached to the back cover 23 . The retaining member 261 abuts on the back surface of the back cover 23 around the attachment hole 231 to prevent the band 26 from detaching from the back cover 23 . As a result, both ends of the band 26 are supported by the back cover 23 .

When the band 26 is not used, such as when the cover body 2 of the file 1 is opened and closed, the band 26 is exposed on the surface side of the back cover 23 and near the lower edge and the outer edge of the back cover 23 as shown in FIG. It will be in a state of being stretched obliquely between However, the band 26 at this time is not subjected to tension and is not deformed under tension. The total length of the band 26 is slightly longer than the linear distance between the two mounting holes 231 at which both ends of the band 26 are mounted, and the band 26 is loose.

On the other hand, when using the band 26 to keep the cover body 2 closed, the intermediate portion of the band 26 exposed on the surface side of the back cover 23 is pulled, and the surface (outer surface) side of the front cover 21 That is, the band 26 is wrapped around the side opposite to the back surface (inner surface) facing the paper sheets 4 to be bound and facing the back surface of the back cover 23, and the front surface of the front cover 21 is pressed down by the intermediate portion of the band 26. Meanwhile, the band 26 is hooked to the lower wall 251 and the outer wall 252 of the guard 25 and engaged. As a result, as shown in FIGS. 4 to 7 or 8, the band 26 is obliquely stretched between the lower edge and the outer edge of the front cover 21 on the surface side of the front cover 21. The cover body 2 is prevented from opening so that the front cover 21 separates from the back cover 23.例文帳に追加

From one mounting hole 231 exposed on the surface of the back cover 23, it wraps around to the surface side of the front cover 21, and then returns to the surface side of the back cover 23 again to return to the other mounting hole exposed on the surface of the back cover 23. The path to 231 is longer than the total length of band 26 . Therefore, the band 26 engaged with the guard 25 is elastically deformed by the action of tension and is pulled and stretched beyond its original length, binding the front cover 21 and the back cover 23 so as not to open. At this time, the lower edge of the lower and outer corner of the front cover 21 abuts or is very close to the inner surface of the lower wall 251 of the guard 25, that is, the upward surface, and the corner of the front cover 21 The outer edge abuts or is in close proximity to the inner surface of outer wall 252 of guard 25 .

When the band 26 is used to keep the cover 2 closed, the band 26 may be hung over the inner edge of the lower wall 251 and the upper edge of the outer wall 252 of the guard 25, as shown in FIG. However, as shown in FIGS. 4-7, the band 26 may be hung over recesses 253 formed in the edge of the lower wall 251 and the edge of the outer wall 252 of the guard 25 . It is conceivable to use the former when the volume or the number of sheets 4 bound by the binder 3 is small, and the latter when the volume or the number of sheets 4 are large. The lateral width of the lower wall 251 of the guard 25 extending along the lower edge of the back cover 23 is limited to a certain range from the corner area of the back cover 23, that is, the lower and outer corners of the back cover 23. , the cover width of the front cover 21 and the back cover 23. The vertical width of the outer wall 252 of the guard 25 extending along the outer edge of the back cover 23 is also limited to a certain range from the corner area of the back cover 23, i.e. the lower and outer corner of the back cover 23. It is shorter than the cover height of the front cover 21 and the back cover 23. - 特許庁In the former case, the band 26 is hung on the front cover 21 and the guard 25 after closing the cover 2 of the file 1, and conversely, the band 26 is hung on the front cover 21 and the guard 25 to open the cover 2. To make the operation of removing the band 26 simple.

In the latter case, the band 26 extends from the outer surface of the lower wall 251 of the guard 25, i.e., the downward surface, to the outer wall 252 of the guard 25 via the recesses 253 on the edges of the lower wall 251 and the outer wall 252. is bridged so as to reach the outer surface, that is, the outer surface of the The band 26 exerts an elastic force to press the lower wall 251 and the outer wall 252 toward each other. Therefore, as shown in FIG. 5, the lower wall 251 of the guard 25 (particularly, the portion around the recess 253) is deformed such that it tilts upward U, and the outer wall 252 of the guard 25 (particularly, the portion around the recess 253) is deformed. A deformation such that the peripheral portion) is tilted inward I occurs. As a result, the inner surfaces of the lower wall 251 and the outer wall 252 of the guard 25 come into contact with and hold the lower edge and outer edge of the corner of the front cover 21, respectively, and the front cover 21 separates from the back cover 23. Thus, the cover body 2 is surely prevented from opening, and the paper sheets 4 bound between the front cover 21 and the back cover 23 are also suppressed from protruding due to hanging down.

In the process of distribution of the files 1 of this embodiment, etc., when packing and transporting a plurality of files 1, as shown in FIG. be able to. That is, with the cover body 2 of each file 1 closed and the band 26 not hung on the guard 25 but placed on the front side of the back cover 23, the front cover 21 of one file 1 and the front cover of the other file 1 are attached. 21 are superimposed. At this time, the lower and inner corners of the front cover 21 of one file 1 and the lower edge of the back cover 22 come into contact with the inner surfaces of the lower wall 251 and outer wall 252 of the guard 25 of the other file 1. Close or very close. At the same time, the lower and inner corners of the front cover 21 of the other file 1 and the lower edge of the back cover 22 abut against the inner surfaces of the lower wall 251 and the outer wall 252 of the guard 25 of the other file 1. or very close. Then, one file 1 is positioned with respect to the other file 1 .

In the present embodiment, a front cover 21 and a back cover 23 that can be relatively rotated to open and close, and a binding that binds the paper sheets 4 between the front cover 21 and the back cover 23 that face each other when closed. and a binding member 3, which is provided along the lower edge of the back cover 23 which is one of the front cover 21 and the back cover 23, stands up toward the front cover 21 which is the other, and is bound by the binding tool 3. A guard 25 that prevents the lower edge of the paper sheet 4 from protruding from the lower edges of the front cover 21 and the back cover 23, and a guard 25 that is supported by the back cover 23 and straddles the lower edge and the outer edge of the closed front cover 21. The file 1 is provided with a band 26 that engages with the guard 25 while hung on the front cover 21 to prevent the front cover 21 and the back cover 23 from opening.

According to this embodiment, even if the dimensions of the covers 21 and 23 of the file 1 are not unnecessarily increased, the bound paper sheets 4 are appropriately prevented from hanging down due to their own weight and protruding from the covers 21 and 23. Unexpected opening of 21 and 23 can be appropriately suppressed.

The guard 25 comprises a lower wall 251 extending along the lower edge of the back cover 23 and an outer wall 252 extending along the outer edge of the back cover 23 and connecting to the lower wall 251. , substantially L-shaped, the necessary and sufficient strength and rigidity can be imparted to the guard 25. - 特許庁

Since at least part of the guard 25 tilts upward U when the band 26 is engaged, the hanging of the bound paper sheets 4 and the unintentional opening of the closed covers 21, 23 are prevented. can be suppressed more effectively.

The guard 25 is formed integrally with the back cover 23 by folding the pieces 251 and 252 protruding from the back cover 23, thereby simplifying the structure.

In addition, a concave portion 253 with which the band 26 can be engaged is formed in the edge of the guard 25 standing on the front cover 21 from the back cover 23 toward the front cover 21 . By hooking the band 26 on the recess 253 when using the band 26, it is possible to effectively prevent the band 26 from coming off unexpectedly. In addition, as shown in FIGS. 6 and 7, the band 26 is accommodated within the recess 253 and does not protrude greatly from the edge of the guard 25, so when arranging a plurality of files 1 upright, there is a problem. The band 26 of the file 1 is prevented from interfering with the surface of the cover body 2 (the back cover 23 thereof) of the other file 1, and the band 26 does not interfere with putting in and taking out the file 1.例文帳に追加

The present invention is not limited to the embodiments detailed above. For example, in the above embodiment, the guard 25 has both the lower wall 251 and the outer wall 252 , but the guard 25 may have only the lower wall 251 excluding the outer wall 252 .

Further, it goes without saying that the guard 25 and band 26 may be provided on the front cover 21 instead of on the back cover 23 . In that case, the guard 25 stands up from the front cover 21 toward the back cover 23 . The band 26 is supported by the front cover 21 and engaged with the guard 25 while being hung on the back cover 23 so as to straddle the lower edge and the outer edge of the closed back cover 23. The opening of the cover 23 is suppressed.

In addition, the specific configuration of each part can be modified in various ways without departing from the scope of the present invention.
