Description

File folder

Technical Field

The present invention relates to a folder having an index element storage unit.

Background

A folder which has been formed into a front cover (japanese: watch) and a back cover (japanese: chart) by folding a piece has been widely used in the past. As one of such folders, a folder having a folder body including a front cover and a rear cover and an index element storage unit protruding from an outer edge of the folder body is considered (for example, see patent document 1). The index element housing unit described in patent document 1 is configured such that a base sheet and a top sheet are formed by folding a translucent sheet, and the top sheet is sandwiched between the base sheet and the folder body while the index element can be held in a closed position between the base sheet and the top sheet.

Here, the index element housing described in patent document 1 is configured such that the entire index element housing is disposed on the inner surface side of the back cover of the folder body and the entire top sheet is sandwiched between the back cover of the folder body and the base sheet, or is configured such that the outer edge portion of the folder body has a protruding portion and the entire top sheet is sandwiched between the protruding portion and the base sheet. Therefore, there is a disadvantage that the operation of opening and closing the index element housing section, i.e., the operation of releasing the closed posture and the operation of returning to the closed posture, which are performed to dispose a new index element between the base sheet and the top sheet, are complicated.

Detailed Description

< first embodiment >

As shown in fig. 1 to 5, a document holder 1A according to a first embodiment of the present invention includes a document holder main body 2 and an index element housing portion 3, the index element housing portion 3 protrudes from an outer edge 2a of the document holder main body 2 and can take a closed posture (C) in which an index element can be sandwiched between a base sheet 4 and a top sheet 5, and the closed posture (C) can be held by sandwiching only a tip end portion 5a of the top sheet 5 between the base sheet 4 and the document holder main body 2.

As shown in fig. 1 to 4, the folder body 2 is formed by folding a translucent sheet to form a front cover 6 and a back cover 7, and an outer edge 2a constituting a long side of the front cover 6 and the back cover 7 and an edge 2b constituting one short side adjacent to the outer edge 2a are opened, and an edge 2c constituting the other short side is welded to each other. In this embodiment, for example, the lower edges in fig. 1 to 3 are welded to each other at the short-side welded portion 2 d.

As shown in fig. 1 to 3 and 5, the index element housing portion 3 is formed by folding a translucent sheet so as to constitute the base sheet 4 whose base 41 is engaged with the outer surface side of the folder body 2 and the top sheet 5 provided continuously to the tip of the base sheet 4. That is, both the base sheet 4 and the top sheet 5 have light permeability.

As shown in fig. 1 to 3 and 5, the substrate 4 includes: a base sheet main body 40 projecting outward beyond the outer edge 2a of the cover, and a base portion 41 continuing to the base end of the base sheet main body 40 and welded to the outer surface 7a side of the back cover 7. The base sheet main body 40 is, for example, a rectangular member having a shape and a size corresponding to the floating mark M as an index element, and the base sheet main body 40 is provided with an attaching region 40A of the floating mark M. A thread 40b formed by embossing is provided on the base sheet body 40 at a position corresponding to the end of the sticking region 40A of the floating label M. The base portion 41 has a length dimension larger than that of the substrate main body 40, and notch portions 41a for dispersing stress are formed in the vicinity of both ends in the longitudinal direction. The base 41 is welded to the back cover 7 by a basic welding portion 41b substantially parallel to the outer edge 2a of the folder body 2 and an auxiliary welding portion 41c located outside the basic welding portion 41b, and the auxiliary welding portion 41c is provided close to one side of the index element housing 3, more specifically, the edge 2c side where the short side welding portion 2d is provided.

As shown in fig. 1 to 3 and 5, the top sheet 5 is continuous with the distal end of the base sheet main body 40 via a folding line 3a, and is folded at the folding line 3a, whereby the top sheet 5 is overlapped with the entire base sheet main body 40, and the distal end 5a of the top sheet 5 is overlapped with a part of the base portion 41 of the base sheet 4.

Fig. 6 is a diagram showing a state in which the index element housing section 3 is in an open posture (O) in which a floating tag M can be inserted between the base sheet 4 and the top sheet 5. The upper column of the figure is a perspective view showing the index element housing section 3 in an enlarged manner, and the lower column is a schematic sectional view taken along the line a-a in the perspective view. The schematic cross-sectional view exaggeratedly shows the thickness of the sheet constituting the folder body 2 and the index element housing part 3, respectively, for easy understanding. In the development posture (O), the sticking region 40A of the floating label M on the base sheet 4 is opened, and the floating label M can be stuck to the sticking region 40A. The floating label M can be sandwiched between the top sheet 5 and the base sheet main body 40 by folding back the top sheet 5 so as to overlap the base sheet main body 40 with the folded line 3a as a boundary in a state where the floating label M is attached to the attachment region 40A. By inserting and clamping the tip end portion 5a of the top sheet 5 between the base portion 41 of the base sheet 4 and the back cover 7 of the folder body 2 in this clamped state, the index element housing portion 3 is brought into the aforementioned closed posture (C), and the closed posture (C) can be maintained. Fig. 7 is a diagram showing a state in which the index element housing section 3 is held in the closed posture (C). The upper column of the figure is a perspective view showing the index element housing section 3 in an enlarged manner, and the lower column is a schematic sectional view taken along the line B-B in the perspective view. The diagrammatic cross-sectional view also shows the thickness of the sheet exaggerated for ease of understanding.

In the folder having such a configuration, the floating tag M held in the index element housing 3 is in a state of protruding outward from the outer edge 2a of the folder body 2, and therefore the visibility of the index is good. Further, since the closed posture (C) can be maintained by merely sandwiching the distal end portion 5a of the top sheet 5 between the base sheet 4 and the folder body 2, the opening and closing operation of the index element housing section 3 is simple and easy. That is, in this embodiment, by deforming mainly the upper side of the index element housing section 3 to be curved toward the back surface side by elastic deformation of the member, the distal end portion 5a of the top sheet 5 can be pulled out from between the base sheet 4 and the folder main body 2, and the top sheet 5 can be unfolded to the unfolded posture (O). This operation can be performed by deforming any part of the index element housing unit 3, but in this embodiment, it is preferable to operate the upper side in the drawing because the lower part of the index element housing unit 3 in the drawing is less likely to be deformed. That is, in the base sheet 4, the base portion 41 is engaged with the back cover 7 of the folder body 2 not only at the basic welding portion 41b but also at the auxiliary welding portion 41c located outside the basic welding portion 41b, and the auxiliary welding portion 41c is provided at the lower portion in the figure of the index element housing 3, and therefore, the lower portion of the index element housing 3 in the closed state is less likely to be bent rearward than the upper portion. In other words, if the folder 1A is opened and closed by holding the lower portion of the index element housing unit 3 in the figure during normal use of the folder 1A, unnecessary expansion of the index element housing unit 3 can be suppressed. The position of the auxiliary welding portion 41c is set according to the main use of the folder 1A, and in the present embodiment, is set to a position where the frequency of the right-handed search operation for the index element housing portion 3 while viewing the index content is high, specifically, a lower portion of the index element housing portion 3 in fig. 1 to 3. In the above description, the description has been given with the index element housing unit 3 positioned at the right side of the folder body 2 in fig. 1 to 3, but it goes without saying that the index element housing unit 3 may be used in a posture positioned above the folder body 2. In this case, since the auxiliary welding portion 41c is located at the right end portion of the index element housing portion 3, when the folder 1A is opened and closed while holding the index element housing portion 3 with the right hand, unnecessary expansion of the index element housing portion 3 can be more effectively suppressed.

In this embodiment, the base portion 41 of the base sheet 4 of the index element housing portion 3 is welded to the outer surface side of the folder body 2, and therefore, a document is not jammed. That is, in this embodiment, since the base portion 41 of the base sheet 4 is welded to the outer surface of the back cover 7 constituting the folder body 2, it is possible to prevent the document accommodated between the inner surface of the back cover 7 and the inner surface of the front cover 6 from being caught on the base sheet 4, and to smoothly take in and out the document. Further, since the base portion 41 of the base sheet 4 of the index element housing 3 is welded to the outer surface side of the folder body 2, the base sheet body 40 is protruded from the outer edge 2a of the folder body 2, and only the tip end portion 5a of the top sheet 5 is sandwiched between the base sheet 4 and the folder body 2, the entire index element housing 3 is positioned outside the housing space for documents or the like between the front cover 6 and the rear cover 7 constituting the folder body 2, and the housing space for documents or the like can be widely used. It is needless to say that the base portion 41 of the base sheet 4 may be welded to the outer surface of the front cover 6 constituting the folder body 2.

Further, since the sticking region 40A of the label M is provided in the base sheet 4 and a region for sticking a paper sheet having a self-holding force such as the label M is secured, the label M can be stuck to the sticking region 40A of the label M, and the index can be prevented from dropping off. That is, in this embodiment, since the float M having a self-holding force is used as the index element, the self-holding force of the float M can be utilized in addition to the sandwiching force between the base sheet 4 and the top sheet 5, and the index element can be more effectively prevented or suppressed from falling off. It is needless to say that the attachment region 40A of the float M may be provided on the top sheet 5.

Further, since the thread 40b formed by embossing is provided in the lower portion of the surface of the sticking region 40A of the floating label M to which the floating label M is stuck, the floating label M can be aligned, and the opening portion is narrowed by deformation of the sheet by embossing, so that the accommodated floating label M is less likely to fall. That is, in the present embodiment, the thread 40b formed by embossing is provided at both ends of the sticking region 40A of the floating mark M of the base sheet 4 made of a sheet, and the base sheet 4 is deformed so as to be slightly bent in the thickness direction by the influence of the thread 40b formed by embossing to close both ends of the index element housing section 3, but the base sheet 4 may be deformed so as to bulge toward the top sheet 5 side according to the manner of implanting the thread formed by embossing, and in this case, the force of sandwiching the index element between the base sheet 4 and the top sheet 5 can be increased.

< second embodiment >

Next, a folder 1B according to a second embodiment of the present invention will be described. In the following description, the same names and symbols are given to the same or corresponding portions as those in the first embodiment, and the description thereof will be omitted or simplified.

This folder 1B is different from the folder 1A of the first embodiment in the following points, and has the same configuration as the folder 1A of the first embodiment in other points. The following description deals with differences from the first embodiment.

As shown in fig. 8 to 11, the file 1B is provided with a retaining stopper 8 for inserting and holding the corner 6c of the front cover 6 on the inner surface 7B of the corner 7c of the back cover 7. The retaining stopper 8 is formed integrally with the back cover 7 with a proximal end portion thereof being folded back toward the inner surface 7b of the back cover 7 with the fold line 8a as a boundary, and a distal end edge 8b of the retaining stopper 8 is welded to the back cover 7 at a stopper welding portion 8 c.

The index element housing portion 3 has the same configuration as that of the first embodiment, and can maintain the closed posture (C) by sandwiching only the distal end portion 5a of the top sheet 5 between the base sheet 4 and the folder body 2. Fig. 12 is an explanatory diagram showing the development posture (O) of the index element housing section 3. The upper column of the figure is a perspective view showing the index element housing section 3 in an enlarged manner, and the lower column is a schematic sectional view taken along the line C-C in the perspective view. The schematic cross-sectional view exaggeratedly shows the thickness of the sheet for easy understanding. Fig. 13 is an explanatory diagram showing a closed posture (C) of the index element housing section 3. The upper column of the figure is a perspective view showing the index element housing section 3 in an enlarged manner, and the lower column is a schematic sectional view taken along the line D-D in the perspective view. The diagrammatic cross-sectional view also shows the thickness of the sheet exaggerated for ease of understanding.

In the file having such a configuration, the front cover 6 is inserted into the anti-separation stopper 8, and the file body 2 can be appropriately held in the closed posture, all of the operational effects of the first embodiment as described above are achieved. The retaining stopper 8 may be a separate member welded to the back cover 7, but if it is formed integrally, the man-hours required for manufacturing can be reduced.

< third embodiment >

Next, a folder 1C according to a third embodiment of the present invention will be described. In the following description, the same names and symbols are given to the same or corresponding portions as those in the first and second embodiments, and the description thereof will be omitted or simplified.

This folder 1C is similar in appearance to the folder 1B of the second embodiment, but is different in construction in the following respects.

That is, as shown in fig. 14 to 16, the folder 1C has the following structure: the document holder is different from the document holders according to the first and second embodiments described above in that the base portion 41 of the base sheet 4 is welded to the outer edge 2a of the document holder body 2, a part of the document holder body 2 is projected, and only the tip portion 5a of the top sheet 5 is sandwiched between the base sheet 4 and the projected portion 20 of the document holder body 2. In the third embodiment, as shown in fig. 14 to 17, the base portion 41 of the base sheet 4 is welded to a portion along the outer edge 2a of the back cover 7 constituting the folder body 2, and a protruding portion 71 is integrally formed at a portion of the back cover 7 corresponding to the base sheet 4, and the index element housing 3 is held in the closed posture (C) by the tip end portion 5a of the top sheet 5 being sandwiched between the protruding portion 71 of the back cover 7 and the base sheet 4. In the file folder 1C according to the third embodiment, as shown in fig. 14 to 16 and 18, the base sheet 4, the top sheet 5, and the retaining stopper 8 are integrally formed by punching the same sheet, and the base end 8x of the retaining stopper 8 is integrally continuous with the base sheet 4 via the base welded portion 41a along the outer edge 2a of the file folder main body 2. As in the file 1B of the second embodiment, the distal edge 8B of the retaining stopper 8 is welded to the inner surface 7B of the back cover 7 by a stopper welding portion 8 c.

As shown in fig. 14 to 17 and 19 to 20, the index element housing portion 3 has a floating label attachment region 5A on the top sheet 5, and a thread 5b formed by embossing is provided on the top sheet 5 at a portion corresponding to an end of the floating label attachment region 5A. That is, the index element housing 3 is configured to attach the floating mark M to the top sheet 5 in the open posture (O), and then to fold back the top sheet 5 so as to be overlapped with the base sheet 4, whereby the contents of the floating mark M can be visually recognized through the base sheet 4, and in the closed posture (C), only the tip end portion 5a of the top sheet 5 is inserted and held between the base sheet 4 and the protruding portion 20 of the back cover 7, whereby the closed posture (C) can be maintained. Fig. 19 is an explanatory diagram showing the development posture (O) of the index element housing unit 3. The upper column of the figure is a perspective view showing the index element housing section 3 in an enlarged manner, and the lower column is a schematic sectional view taken along the line E-E in the perspective view. The schematic cross-sectional view exaggeratedly shows the thickness of the sheet for easy understanding. Fig. 20 is an explanatory diagram showing a closed posture (C) of the index element housing section 3. The upper column of the figure is a perspective view showing the index element housing section 3 in an enlarged manner, and the lower column is a schematic sectional view taken along the line F-F in the perspective view. The diagrammatic cross-sectional view also shows the thickness of the sheet exaggerated for ease of understanding.

Even in the file having such a configuration, the front cover 6 is inserted into the anti-slip stopper 8, so that the file body 1C can be appropriately held in the closed posture, while the main operational effects of the first embodiment described above are exhibited.

The retaining stopper may be formed separately from the index element housing portion, or the retaining stopper itself may be omitted.

In the third embodiment, the case where the index element housing part is welded to the inner surface of the folder body, in other words, the inner surface of the back cover, has been described, but the index element housing part may be welded to the outer surface of the outer edge of the folder body, in other words, the outer surface of the back cover, for example. In this case, the protruding portion provided on the outer edge of the back cover is located on the front surface side of the base sheet, and therefore, it is preferable that the attachment region of the floating tag is provided not on the top sheet but on the base sheet. Further, the index element housing may be welded to the front cover of the folder body.

Furthermore, the present invention is not limited to the embodiments described above.

For example, in the above embodiments, the index element is a float, but the index element is not limited to a float, and may be a sheet of paper having other shapes such as a rectangular shape without self-holding force, a linear index element, or the like.

In the above embodiments, both the base sheet and the top sheet of the index element housing portion have transparency such that the contents of the floating tag housed in the index element housing portion can be read from the outside, but only one of the base sheet and the top sheet of the index element housing portion may have transparency. One or both of the base sheet and the top sheet of the index element storage unit may be a translucent sheet such as ground glass having a degree that the color of the index element, the shape of the symbol, or the like can be determined from the outside, or a sheet having meshes and/or holes formed in an opaque sheet material.

In the above embodiments, the front cover and the back cover of the folder body are formed by folding the translucent sheet, but the sheet constituting the folder body is not limited to the translucent sheet. It is needless to say that a folder body in which a sheet forming the front cover and a sheet forming the back cover are overlapped and adjacent two sides are engaged by welding or the like may be used.

The index element housing portion may be provided at a certain position on the outer edge of the folder body. Further, a plurality of folders having different positions of the index element storage unit may be used in combination.

In addition, various modifications are possible within a range not to impair the gist of the present invention.
