Description

Structure of folder

Technical Field

The invention relates to a structure of a cover which can be applied to folders and other stationery.

Background

As a folder for arranging various documents, it is known to provide a binder capable of binding sheets, a pocket capable of storing sheets, and the like. The cover of such a file is generally formed in a plate shape integrally with a cover back and a front cover and a back cover connected to both edges of the cover back. Further, the material of the jacket may be cardboard, polypropylene film attached to a cardboard core, or resin molded product.

In the cover of the above-mentioned folder, for the purpose of enhancing the degree of freedom of the design, it is conceivable that the back of the cover is separated from the front cover and the bottom cover. For example, a cover of a folder or the like may be configured by joining a predetermined portion of a back member having a back cover to a front cover or a back cover in a state of being superposed thereon.

However, a plurality of folders and the like are often housed in a rack in parallel, and there is a problem that the joining portion of the back member and the front cover or the bottom cover hooks the adjacent folders and the like when housing or taking out. That is, the back cover, the front cover, and the bottom cover are made to be separate from each other, which may cause a reduction in usability of the folder or the like.

Disclosure of Invention

In view of the above problems, an object of the present invention is to realize a structure capable of constituting a cover of a folder or other stationery by a back cover, a front cover and a back cover which are mutually separated while ensuring the convenience of use.

In order to solve the above problems, the present invention provides a cover comprising a back member including a cover back and a mounting portion connected to the cover back via a hinge, and a surface cover or a bottom cover which is separate from the back member, wherein the mounting portion is joined to one of the surface cover or the bottom cover in a state of being overlapped from inside on the other edge portion, and wherein a connecting portion is formed on one side substantially along the edge of the other edge portion, and the connecting portion is formed as an inclined outer surface which makes the outer surface of the one side and the outer surface of the other edge portion substantially continuous when the one side and the other side are joined.

That is, the wall thickness portion is provided so as to cover the edge end face of the other edge portion and to form an outer surface in which the outer surface of the one outer surface and the outer surface of the other edge portion are gently and substantially continuous when the one and the other are joined. With this configuration, when the cover is stored in or taken out from the rack or the like, the end face of the other edge portion arranged outside, that is, the joining portion of the back member to the front cover and the bottom cover does not catch an adjacent folder or the like, and the usability of the folder or other stationery having the cover is not impaired.

The cover as used herein is a concept including all covers provided on the outer side of folders, books, and other stationery items for protection, decoration, and presentation of contents. Therefore, the object of the structure of the jacket according to the present invention is to be referred to as a file, a binder, a clip, and various other stationery items.

Alternatively, the skin may be configured to include a back member including a back cover and a mounting portion connected to the back cover via a hinge, and a surface skin or a bottom skin that is separate from the back member, and to join the mounting portion to one of the edge portions of the surface skin or the bottom skin while overlapping the other edge portion from inside, wherein a connecting portion (or a wall thickness portion having a set thickness) is formed on one side substantially along the edge of the other edge portion, and the connecting portion is formed so as to have an outer surface that is continuous substantially coplanar with an outer surface of the other edge portion when the one side and the other side are joined.

When the contact portion contacting at least a part of the end face of the one edge portion is projected toward the inside of the other edge portion, the back member, the surface skin and the bottom skin can be positioned relative to each other when the back member, the surface skin and the bottom skin are joined.

If the back member is a resin integral molding, the degree of freedom in designing the shape thereof is increased. In particular, unlike a conventional one-sheet-shaped cover, it is possible to provide a recess that does not penetrate the back member, and such a recess may be provided as an operation portion for taking out a folder or the like from a document holder.

Further, with the above-described structure of the cover, it is possible to construct a cover including a cover back and a front cover or a back cover connected to the cover back via a hinge, and to create a file in which sheets of various documents and the like can be accommodated, sandwiched, or bound in the cover.

Detailed Description

An embodiment of the present invention is explained below with reference to the drawings. Shown in fig. 1 to 7 are folders utilizing the structure of a jacket according to the present invention. The cover 1 of the file folder comprises a cover back 111, a front cover 12 connected to the cover back 111 via a hinge 112, and a bottom cover 13 connected to the cover back 111 via a hinge 113.

In detail, the split leather back 111 and the hinges 112, 113 are present as a part of the back member 11 as shown in fig. 5, 6, and the like. That is, the back member 11 includes the back cover 111 and the mounting portions 114 and 115 connected to the back cover 111 via the hinges 112 and 113. The back member 11 shown in the drawing is formed by integrally molding the back cover 111 and the mounting portions 114 and 115, and may be formed as a resin integrally molded product, for example. The hinges 112 and 113 are formed by bending the leather-covered back 111 at the boundary between the attaching portions 114 and 115.

The mounting portion 114 is a portion that engages the split leather 12. The attachment portion 114 is, as shown in fig. 4, 6, and the like, substantially flat plate-like, and an edge of the edge portion 114a away from the back side of the jacket is formed in a curved shape bulging outward in a front view. Further, a contact portion 114b is provided at the upper end of the inward surface of the mounting portion 114, a contact portion 114c is provided at the lower end, and a contact portion 114d is provided at the side end (boundary portion with the hinge 112) on the back side of the split leather so as to protrude inward in the normal direction. The length of the contact portions 114b, 114c, 114d is preferably set to substantially correspond to the thickness of the edge portion 12a of the jacket 12. The mounting portion 115 is a portion to which the bottom jacket 13 is joined. The attachment portion 115 is also substantially flat, and the edge of the edge portion 115a away from the back side of the skin is formed in a curved shape bulging outward in front view. Further, a contact portion 115b is provided at the upper end of the inward surface of the mounting portion 115, a contact portion 115c is provided at the lower end, and a contact portion 115d is provided at the side end (boundary with the hinge 113) on the back side of the split leather so as to protrude inward in the normal direction. The protruding length of these contact portions 115b, 115c, 115d preferably corresponds approximately to the plate thickness of the edge portion 13a of the bottom jacket 13. In the illustrated example, the mounting portion 115 has a shape substantially symmetrical to the mounting portion 114.

On the other hand, the top sheet 12 and the bottom sheet 13 are both substantially rectangular flat plates as shown in fig. 5, 6, and the like. The top cover 12 and the bottom cover 13 may be formed as a resin molded product, for example. The vertical dimension of the dough cover 12 is set approximately in accordance with the dimension of the mounting portion 114. Further, a cutout portion 12b is formed by cutting a part of the upper end of the side edge portion 12a contacting the back side of the jacket, and a cutout portion 12c is formed by cutting a part of the lower end of the side edge portion 12 a. The dimension of the cutout portion 12b in the vertical direction substantially corresponds to the dimension of the contact portion 114b provided in the mounting portion 114 in the vertical direction, and the dimension of the cutout portion 12c in the vertical direction substantially corresponds to the dimension of the contact portion 114c provided in the mounting portion 114 in the vertical direction. Further, a thick portion 121 serving as a connecting portion is provided inside the edge portion 12a of the surface jacket 12. The thick portion 121 is formed in accordance with the shape of the edge portion 114a of the mounting portion 114 away from the back side of the jacket so as to be in contact with the side end of the back side of the jacket. Also with respect to the bottom sheet 13, the vertical dimension thereof is set substantially in accordance with the corresponding dimension of the mounting portion 115. Further, a cutout portion 13b is formed by cutting a part of the upper end of the side edge portion 13a contacting the back side of the jacket, and a cutout portion 13c is formed by cutting a part of the lower end of the side edge portion 13 a. The dimension of the cutout portion 13b in the vertical direction substantially corresponds to the dimension of the contact portion 115b provided in the mounting portion 115 in the vertical direction, and the dimension of the cutout portion 13c in the vertical direction substantially corresponds to the dimension of the contact portion 115c provided in the mounting portion 115 in the vertical direction. Further, a thick portion 131 as a connecting portion is provided inside the edge portion 13a of the bottom jacket 13. The thick wall portion 131 is formed in accordance with the shape of the edge portion 115a of the mounting portion 115 away from the back side of the jacket so as to contact the side end of the back side of the jacket. In the illustrated example, the bottom jacket 13 has a shape substantially symmetrical to the top jacket 12.

In this embodiment, the split cover 1 is configured by joining the edge portion 12a of the surface split cover 12 to the edge portion 114a of the attachment portion 114 from the inside and joining the edge portion 13a of the bottom split cover 13 to the edge portion 115a of the attachment portion 115 from the inside. When joining the surface split 12 and the attachment portion 114, the end face of the cutout portion 12b of the edge portion 12a of the surface split 12 is brought into contact with the contact portion 114b of the attachment portion 114, so that upward relative movement of the surface split 12 with respect to the attachment portion 114 can be inhibited, and the end face of the cutout portion 12c of the edge portion 12a of the surface split 12 is brought into contact with the contact portion 114c of the attachment portion 114, so that downward relative movement of the surface split 12 with respect to the attachment portion 114 can be inhibited. Further, the side end surface of the edge portion 12a of the surface skin 12 is brought into contact with the contact portion 114d of the mounting portion 114, and relative movement of the surface skin 12 to the mounting portion 114 in the width direction and the back side of the skin can be inhibited. Similarly, when the bottom split leather 13 and the mounting portion 115 are joined, the end face of the cutout portion 13b of the edge portion 13a of the bottom split leather 13 is brought into contact with the contact portion 115b of the mounting portion 115, so that upward relative movement of the bottom split leather 13 with respect to the mounting portion 115 can be inhibited, and the end face of the cutout portion 13c of the edge portion 13a of the bottom split leather 13 is brought into contact with the contact portion 115c of the mounting portion 115, so that downward relative movement of the bottom split leather 13 with respect to the mounting portion 115 can be inhibited. Further, the side end surface of the edge portion 13a of the bottom leather 13 is brought into contact with the contact portion 115d of the mounting portion 115, and relative movement of the bottom leather 13 to the mounting portion 115 in the width direction and the leather back side can be inhibited.

The thickness portion 121 is formed in advance so that the outer surface of the edge portion 114a of the attachment portion 114 and the outer surface of the surface skin 12, that is, the outer surface of the panel portion 12d on the side away from the attachment portion with respect to the edge portion 12a are substantially continuously inclined when the surface skin 12 and the attachment portion 114 are joined. More specifically, as shown in fig. 7, the thickness of the thick-walled portion 121 is set so that the outer surface of the edge portion 114a of the mounting portion 114 and the outer surface of the thick-walled portion 121 become substantially coplanar with each other in the vicinity of the boundary between the mounting portion 114 and the thick-walled portion 121. Further, the outer surface of the wall thickness portion 121 is inclined in a horizontal sectional view (with respect to the outer surface of the rim portion 114a of the mounting portion 114 and the outer surface of the panel portion 12 d), so that the outer surface of the rim portion 114a of the mounting portion 114 and the outer surface of the panel portion 12d are smoothly and substantially continuous. As described above, the thick portion 121 is formed substantially along the edge of the edge portion 114a of the main view mounting portion 114. With this configuration, the edge end face of the edge portion 114a of the mounting portion 114 existing on the outside is appropriately covered by the thick portion 121, and the outer surface of the thick portion 121 covers the gap between the outer surface of the edge portion 114a of the mounting portion 114 and the outer surface of the panel portion 12 d. Similarly, the thick wall portion 131 is formed in advance so that, when the bottom sheet 13 and the mounting portion 115 are joined, the outer surface of the edge portion 115a of the mounting portion 115 and the outer surface of the bottom sheet 13, that is, the outer surface of the panel portion 13d on the side away from the mounting portion than the edge portion 13a become a substantially continuous inclined outer surface. More specifically, as shown in fig. 7, the thickness of the thick portion 131 is set so that the outer surface of the edge portion 115a of the mounting portion 115 and the outer surface of the thick portion 131 become substantially coplanar with each other in the vicinity of the boundary between the mounting portion 115 and the thick portion 131. Further, the outer surface of the wall portion 131 is inclined in a horizontal sectional view (with respect to the outer surface of the flange portion 115a of the mounting portion 115 and the outer surface of the panel portion 13 d), so that the outer surface of the flange portion 115a of the mounting portion 115 and the outer surface of the panel portion 13d are smoothly and substantially continuous. As described above, the thick portion 131 is formed substantially along the edge of the edge portion 115a of the front view mounting portion 115. With this configuration, the edge end face of the edge portion 115a of the mounting portion 115 existing on the outside is appropriately covered by the thick portion 131, and the outer surface of the thick portion 131 covers the gap between the outer surface of the edge portion 115a of the mounting portion 115 and the outer surface of the panel portion 13 d. Incidentally, in the surface skin 12 of the illustrated example, the bottom skin 13 is formed so that the boundary line between the thick wall portions 121 and 131 and the panel portions 12d and 13d is exposed, and the aesthetic appearance is further improved when the thick wall portions 121 and 131 having inclined surfaces are bulged in the thickness direction.

As shown in fig. 4 and 6, a binding clip 2 for binding sheets is provided on the jacket 1 of the above type, and functions as a file. Instead of the binder 2, the cover 1 may be provided with a pocket for receiving sheets, a holder for holding sheets, or the like, and may function as a folder.

In the present embodiment, the back member 11 is provided with a recess 116 that does not penetrate the back member 11. Such a recess 116 is open on the back side of the jacket as shown in fig. 1-3. Thus, even when a folder or the like including the cover 1 of the present embodiment is stored in a rack, the folder can be easily taken out by inserting a finger of a person into the recess 116 from the back side of the cover and operating the folder. Further, since the recess 116 is also opened to the surface-clad sheet side or the bottom-clad sheet side, the operability when the user inserts his or her finger into the recess 116 to operate the finger is further improved.

Therefore, in the present embodiment, the back member 11 including the back cover 111 and the attaching portions 114 and 115 connected to the back cover 111 via the hinges 112 and 113, and the surface skin 12 and the bottom skin 13 which are separate from the back member 11 are provided, and in a state where the attaching portion 114 is overlapped with the edge portion 114a of the attaching portion 114 which is the other one from the inside, the attaching portion 114 is joined to the edge portions 12a and 13a of the surface skin 12 and the bottom skin 13 which are one of the surface skin 12 and the bottom skin 13, in the skin 1, the wall thickness portions 121 and 131 having a predetermined thickness are formed on the surface skin 12 and the bottom skin 13 substantially along the edge of the edge portion 114a of the attaching portion 114 so that the outer surfaces of the panel portions 12d and 13d of the surface skin 12 and the bottom skin 13 and the attaching portion 114 become an inclined outer surface substantially continuous with the edge portion 114a of the attaching portion 114, this allows the edge end surfaces of the edge portions 114a, 115a of the mounting portions 114, 115 disposed on the outer sides to be appropriately covered by the thick portions 121, 131, and the gaps between the outer surfaces of the edge portions 114a, 115a of the mounting portions 114, 115 and the outer surfaces of the panel portions 12d, 13d to be covered by the outer surfaces of the thick portions 121, 131. Thus, when the cover is stored in a rack or the like or when the cover is taken out from the rack or the like, the edge end faces of the edge portions 114a and 115a of the mounting portions 114 and 115 arranged on the outer sides do not catch an adjacent folder or the like, and the usability of the folder or other stationery having the cover 1 is not impaired.

The contact portions 114b, 114c, 114d, 115b, 115c, 115d, which are brought into contact with at least a part of the end faces of the edge portions 12d, 13d of the surface and bottom jackets 12, 13, are projected toward the inner sides of the mounting portions 114, 115, whereby the mounting portions 114, 115 can be positioned and joined to the surface and bottom jackets 12, 13, respectively, and the manufacturing process can be simplified.

Since the back member 11 is formed as a resin integral molding unlike a jacket of a conventional file or the like in a single plate shape, it is possible to perform processing such as forming a recess 116 not penetrating the back member 11.

Since the back member 11 is provided with the recess 116 that does not penetrate the back member 11, it is easy to insert a human finger into the recess 116 and perform an operation.

Further, if the cover 1 including the cover back 111 and the front cover 12 or the bottom cover 13 connected to the cover back 111 via the hinges 112 and 113 is constituted by the structure of the cover 1 as described above, and a folder capable of being sandwiched or bound by accommodating sheets of various documents or the like in the cover 1 is manufactured, it is possible to achieve both of good usability and freedom in design.

Furthermore, the present invention is not limited to the embodiments described in detail above. For example, the connecting portion is not limited to the thick portion as illustrated in the drawing, and may be a portion having a recess inside. The front view shape of the edge portion of the attachment portion is not limited to the curved shape bulging away from the back side of the skin as in the above-described embodiment, and may be a straight shape extending in the vertical direction. The arrangement of the recesses provided in the back member, the number and the size thereof, and the like are not limited to those illustrated in the drawings. In particular, it is possible to construct the skin according to the present invention by joining the edge portion of the attachment portion to the edge portion of the surface skin or the bottom skin so as to overlap the edge portion of the surface skin or the bottom skin from the inside.

Further, as a modification of the present invention, the structure of the split leather shown in fig. 8 may be configured. That is, this is a structure of the cover 1 comprising a back member 11 including a cover back 111 and attaching portions 114, 115 connected to the cover back 111 via hinges 112, 113, and a surface cover 12X and a bottom cover 13X which are separate from the back member 11, and joining the attaching portion 114 to edge portions 12Xa, 13Xa of the surface cover 12X and the bottom cover 13X which are one of the surface cover 12X and the bottom cover 13X in a state of being overlapped from the inside on an edge portion 114a of the attaching portion 114 which is the other, in which wall thickness portions 12X1, 13X1 are formed as connecting portions on the surface cover 12X and the bottom cover 13X substantially along an edge of the edge portion 114a of the attaching portion 114, and these wall thickness portions are set to such a thickness that outer surfaces of the surface cover 12X and the bottom cover 13X are positioned at the time of joining the surface cover 12X, the bottom cover 13X and the attaching portion 114, that are positioned at the edge portions 12Xa, 13Xa, The outer surfaces of the panel portions 12Xd and 13Xd of the mounting portion 13Xa on the side away from the mounting portion are continuous substantially coplanar with the outer surface of the edge portion 114a of the mounting portion 114. Even with this configuration, the edge end face of the edge portion 114a of the mounting portion 114 can be appropriately covered, and the same effects as those of the above embodiment can be obtained. Since the structure of the other parts can be used as it is in the above embodiment, the description thereof will be omitted here.

The specific configuration of the other parts is not limited to the above embodiment, and various modifications are possible within a range not departing from the spirit of the present invention.

The invention described in detail above can ensure the convenience of use, and can form file folder and other stationery folder with split back cover, face cover and bottom cover.
