Description

  The present invention relates to a substantially U-shaped file for binding and saving documents, booklets, and the like, and in particular, it is possible to easily extract only a specific file in a state where the file is densely stored on a shelf or the like. Concerning structure.

  The file for binding and saving documents and booklets is a combination of hard paper, hard resin board material, hard paper and soft vinyl cover to protect the documents and booklets bound inside. For example, a folded part is formed between the left and right face parts and the back part, the file itself can be folded and expanded in a substantially U shape, and the inner part of the back part is bound together. The binder and the booklet are detachably stored in the file through the binder.

  These files are generally stored in the same standard size, with the back part facing up and placed on a shelf, etc., arranged in a horizontal row, and the contents are stored by the back heading placed on the back part. There are many exhibitions by item.

  Therefore, when files are closely arranged in this way, the adjacent back cover parts are closely arranged in a horizontal row, and the file itself is hard. There are many cases where there is no gap even if it is inserted and gripped, which makes it difficult to remove.

  You can also insert your finger between the upper edge of the back cover and the shelf on the top of the file and tilt the file toward you, but the space between the shelf and the file is narrow or stored at a high position. Such a sampling operation is difficult to perform.

  In order to eliminate such a drawback of difficulty in taking out, the following Patent Document 1 discloses that a hole or notch for a clue is formed in the lower part or lower end of the back part.

In Patent Document 2 below, a back cover made of a synthetic resin molded product with a clue pocket projecting integrally on the front side is mounted on the back cover paper, and a clasp is provided on the left and right sides of the front cover. Are provided.
Japanese Utility Model Publication No. 58-86374 JP 2000-127666 A

  However, in the structure of Patent Document 1, if the booklet is fully packed in the file, the booklet is in contact with the hole or notch from the inside, and it is difficult to obtain a clue. Similarly, the structure in which the binder is integrally attached to the inner surface of the spine cover does not function as a clue, and there are various problems that are restricted by the binder mounting position.

  On the other hand, the structure of Patent Document 2 has a sufficient effect as a clue at the time of extraction. However, apart from the design appearance, there is a large protrusion called a pocket on the front of the back cover, which interferes with the front glass of the shelf and disturbs storage, and the back cover is molded separately Therefore, there is a problem that the manufacturing cost is high. In addition, the cost increases due to the attachment of the handle, and in the storage state, the left and right adjacent handles collide to reduce the storage density.

  The present invention has been made to solve such a problem, and the object of the present invention is to store the files arranged in a row in a row in a state where the files are stood on a shelf or the like with the back part facing forward. It is to provide a simple and inexpensive file having a structure in which a gap is formed between adjacent back cover parts and a file can be easily taken out by inserting a hand into the gap.

In order to achieve the above-mentioned object, the present invention forms a bent portion between the left and right cover parts 2, 2 and the back cover part 3, as shown also in the embodiment of the figure. In the file 1 in which the left and right front cover parts 2 and 2 can be folded and expanded in a substantially U shape with respect to the back cover part 3,
The pair of bent portions is formed by hinge grooves 4 and 5 that are formed in two lines in the vertical direction on the left and right sides of the back portion 3, and at least one of the hinge grooves is formed on the back portion 3 side. The hinge grooves 4 and 4 are formed in a curved shape toward the back portion 3 at the substantially middle portion in the vertical direction, and are formed as curved portions 4a and 4a.

Also, as shown in the embodiment of FIGS. 1 to 4, the pair of left and right hinge grooves 4, 5 of the left and right hinge grooves 4, 5, respectively, has a pair of left and right hinge grooves 4, 4 formed vertically. A pair of left and right hinge grooves 5, 5 formed on the side of the surface mounting parts 2, 2 are formed as curved parts 4 a, 4 a, which are formed in a curved shape toward the back part 3 side in a substantially middle direction. It is characterized in that it is formed in a curved shape in the opposite direction to form curved portions 5a, 5a.
In this case, the curvature of the curved shape of the curved portion 5a of the hinge groove 5 on the front mounting portion 2 side is larger than the curved shape of the curved portion 4a of the hinge groove 4 on the back mounted portion 3 side.

  Furthermore, as shown in the embodiment of FIGS. 5 and 6, a pair of hinge grooves 23, 23 formed on the back portion 22 side and a pair of hinge grooves 24 formed on the front portion 21, 21 side, 24 is formed in a substantially parallel curved shape toward the back covering portion 22 side at a substantially intermediate portion in the vertical direction to form curved portions 23a and 24a.

  In the file of the present invention, in the substantially U-folded state, the pair of hinge grooves 4, 4 formed on the back portion 3 side and the pair of hinge grooves 5, 5 formed on the front portion 2 side, At least an intermediate part between the left and right front cover parts 2, 2 is formed with a recess 2 a having a reduced diameter and inclined from the side of the back part 3 toward the back part 3, and at least an intermediate part of the back part 3 protrudes forward. 3a is formed.

  In addition, the formation position of the said curved part 4a, the curved part 5a, the said recessed part 2a, and the bulging part 3a can also be formed not only in the vertical center position of the file 1, but the upper part or the lower part.

  Furthermore, in the present invention, the semi-rigid board material constituting the file 1 has a foam material made of a hard foam rubber material or the like as the core A, and a hard resin skin material B is integrally formed on the inner and outer surfaces thereof. It is characterized by being laminated and bonded. The core A and the skin material B can be formed of a thermoplastic synthetic resin, for example, a polypropylene resin.

  Therefore, in the present invention, the file 1 is folded along the curved left and right hinge grooves 4 of the back cover 3, so that a substantially intermediate portion in the height direction of the back cover 3 is a front portion along the curve line. At the same time as the bulging portion 3a bulges to the side, the width is narrower than the upper and lower portions, and the concave portions 2a are formed on both sides of this portion so that the hand can be inserted. Even if it is arranged, the desired file 1 can be easily grasped and taken out from the row. Moreover, since the process is only a blank cut of a hard board material and a muscle pushing process by heat pressure, it can be manufactured easily and inexpensively.

  According to the second aspect of the present invention, when the file 1 is folded, the left and right outer cover parts 2 also have concave portions 2a in which the substantially middle part in the vertical direction is dented along the curved shape, and the hand can be inserted. Further, the recesses 2a of the left and right cover parts 2 are large along the depth direction, and the margin for inserting the hand is increased, which makes it easier to take out.

  Even in the invention of claim 3, since the inclined concave portion 21a continuous from the back portion 21 is formed on the surfaces of the left and right front portions 21, a clue for taking out can be obtained.

  In the invention of claim 5, the molding material itself of the file has moderate rigidity and elasticity, and constitutes a so-called PP hinge after the muscle pushing process, so that the folding part is rich and the hinge part accompanying repeated folding and unfolding. Is also prevented from being damaged.

  The best mode for carrying out the present invention will be described below in detail with reference to the accompanying drawings. 1 to 4 show a first embodiment of the present invention. FIG. 1 is a rear perspective view of a file in an unfolded state, and FIGS. 2A and 2B are a front view and a perspective view of the assembled state. 3 is an enlarged cross-sectional view showing the material structure of the file, and FIGS. 4A and 4B are a front view and a perspective view showing a state in which the file is arranged in a horizontal row on a shelf and a take-out state.

  In FIG. 1, a file 1 has a size corresponding to a paper standard such as a vertically long A plate or B plate series, and an appropriate R is attached to the four circumferences so that the left and right cover parts 2 and the back cover part 3 are continuous. In addition, a single hard board material is blank-cut, and then is pressed at a small distance along the vertical direction on the left and right sides of the back portion 3 by press-fitting by pressure heating such as high-frequency or ultrasonic welding. By forming a pair of hinge grooves 4, 5, the left and right cover parts 2 and the back cover part 3 are partitioned, and the left and right cover parts with respect to the back cover part 3 via the hinge grooves 4, 5. 2 can be folded and expanded in two steps in a substantially planar U shape. The material of the hard board material will be described later.

  Of the hinge grooves 4 and 5, the pair of hinge grooves 4 on the back cover 3 side has a curved portion that draws a gentle arc toward the back cover 3 at the longitudinal intermediate portion of the back cover 3. 4a is formed in mirror symmetry.

  Further, in the pair of hinge grooves 5 on the side of the cover part 2, a curved part 5a having a smaller curvature and a reverse direction is formed in a mirror symmetry at a substantially intermediate portion in the longitudinal direction of the cover part 2.

  After the above molding, as shown in FIG. 2 (a), the binder tool 6 indicated by a broken line is fixed to the inner surface of the backrest portion 3, and the rebound resilience at the hinge portion is prevented and the folded state is maintained. As shown in FIG. 4B by bending or the like, a three-dimensional model is formed into a substantially self-supporting U shape, and the file 1 is completed.

  In the completed state, along the arc surfaces of the curved portions 4a and 5a of the hinge groove 4.5, the bulging portion 3a that gently bulges outward is formed at the substantially central portion of the back portion 2, On the surface mounting part 2 side, the concave part 2a that converges toward the bending part side 5a is formed with both sides of the central part of the back covering part 3 being dented to the maximum, and this part can be used as a clue when pulling out.

  FIG. 3 shows a member configuration of the hard board material constituting the file 1 described above. In the figure, the total thickness d of the board material is about 3 mm, and the core A occupying most of the thickness direction is made of hard foam rubber. The skin material B is sandwiched between the inner and outer surfaces of the core A. Laminated and integrated. These material configurations provide rigidity as a whole, and impart moderate elasticity or flexibility such that the bulging portion 3a and the concave portion 2a can be formed as described above in a state where the file 1 is completed. In addition, the surface of the skin material B is appropriately formed with a grain pattern to make it non-glossy. As the material for the core A and the skin material B constituting the board material, a thermoplastic synthetic resin, for example, a polypropylene resin is suitable.

  When this board material is subjected to a line pushing process, concave groove-like hinge grooves 4 and 5 are formed on the front surface side, and hinge grooves 4 'and 5' made of linear groove grooves are formed on the back surface side. It becomes a hinge in a state where A is crushed. This hinge is a so-called PP hinge, and even if this part is bent frequently, it is not damaged and is a durable hinge.

  In FIG. 4A, the above files 1 are arranged in a horizontal row on the shelf board 10. In this state, the gap formed by the adjacent recesses 3a is doubled, and even if the gap H with the upper shelf board 10 is narrow, as shown in FIG. You will get enough clues to retrieve the desired file.

  5 and 6 show a second embodiment of the present invention, FIG. 5 is a rear perspective view of a file in a developed state, and FIG. 6 is a perspective view of the assembled state. In FIG. 5, the file 20 is formed by dividing the left and right cover parts 21 and the back part 22 by two left and right hinge grooves 23 and 24, as in the first embodiment. Curved portions 23a and 24a that draw gentle arcs substantially in parallel toward the back portion 22 side are formed at the longitudinal center portions of the hinge grooves 23 and 24, respectively.

  In addition, a bellows 25 protrudes from the center of the end portion of one of the cover parts 21, and a number of hinge grooves 26 are formed in the vertical direction on the back surface of the bellows 25. The periphery of the fastener 27 is fixed by means such as welding. Correspondingly, a surface fastener 28 that meshes with the surface fastener 27 is fixed to the side surface of the other cover portion 21 by means such as welding.

  In a state where the above file 20 is folded through the hinge grooves 23 and 24, the three-dimensional model is formed into a substantially U shape as shown in FIG. In this state, a bulging portion 22a that draws a gentle arc is formed in the center of the back portion 22, and a concave portion 21a is formed in the surface portion 21 at the center of the joint surface between the back portion 22 and the left and right surface portions 21. It is formed. The concave portion 21a does not have a large dent compared to the first embodiment, but there is a sufficient clearance for inserting and pulling out a hand as shown in the figure in a densely arranged state.

  Further, the bellows 25 can be freely bent through the hinge groove 26, and the surface fasteners 21 are opened by joining the surface fasteners 27 at the front ends thereof toward the surface fasteners 28 of the other surface cover member 21 as shown by arrows. This is intended to protect documents, booklets and the like bound in the file 20. Instead of the hook-and-loop fastener, a hook or the like can also be used.
