Description

  The present invention relates to a filing tool for binding a paper sheet by inserting a string-like linear body from both front and back sides into the binding hole of the paper sheet.

  Conventionally, as this type of filing tool, a ring-type filing tool having a metal or hard resin ring has been widely used.

  In such a ring-type filing tool, it is possible to remove, replace, and add a paper sheet of an arbitrary page. However, the hardness and bulkiness of the ring are obstacles such as writing or copying in a state where the paper sheet is bound. It is difficult to use, and the closing force of the ring is generally strong, handling requires a strong force, there is a risk of pinching fingers, and handling is also necessary. There were drawbacks.

  Therefore, as a filing tool that does not use a ring, a linear body having a base is placed inside the cover of the filing tool as a filing tool that binds paper sheets with a linear body planted on both sides of the back cover part inside both covers. A device mounted in an upright state is proposed in Patent Document 1 below.

  On the other hand, in the binding type filing tool using the flexible linear body described in Patent Document 1, any page can be edited in the same manner as the ring type filing tool, and the disadvantage that the ring is obstructed is also in operation. The risk of injury is also resolved.

Japanese Patent No. 2933899 JP 11-277940 A

  In order to perform the function of the filing tool, the flexible linear body needs to be formed of a material such as a synthetic resin having a smooth surface and elasticity. However, since the synthetic resin material is slightly plastic, if the linear body is bent by an inadvertent operation at the time of use, a bending wrinkle may occur and the operability may be hindered.

  The present invention has been conceived to solve such a problem, and further enhances the function of the filing tool, and even if it is bent, it functions by replacing parts without leaving damage to the filing tool. It aims to provide a filing tool that can recover.

The first embodiment of the present invention includes a pair of left and right insertion sheets 1 having a linear body 11 shown in the perspective view of FIG. 2B and a cover 2 shown in the perspective view of FIG. Composed,

  The cover 2 is a cover, which is selected according to the application, such as resin, leather, reinforced paper, etc., and is produced by sewing, bonding, welding, etc. suitable for the material. Formed on both sides of the bent portion 20 is a bag-shaped storage portion 21 opened to the bent portion 20 side, and corresponds to the binding hole 41 of the paper sheet 4 to be bound along the opened edge of the storage portion 21. The four insertion holes 22 are opened at the positions to be operated.

  Further, in the bent portion 20 of the cover, the protective sheet 3 shown in FIG. 3 (d) configured so as to be extended and inserted into the left and right storage portions 21 is provided on the left and right inner sides of the bent portion 20 of the cover. It is provided over.

  The upper and lower edges of the protective sheet 3 are fixed to the cover 2 so that only the portion sandwiched between the left and right storage portions 21 is indicated by the dotted line 33, and the extended portion 31 inserted into the left and right storage portions 21 has Four holes 31 are formed at positions corresponding to the four holes 22 opened in the storage portion 21, respectively.

  This protective sheet 3 is made of a thin and flexible material such as leather or a synthetic resin sheet in order to facilitate the insertion of the pair of left and right insertion sheets 1 having the linear body 11 into the left and right storage portions 21. Things are desirable.

  A pair of left and right insertion sheets 1 having a linear body 11 shown in the perspective view of FIG. 2B is inserted into the bag-like storage portion 21 of the cover 2 from the bent portion 20 side of the cover 2. As shown in the perspective view of FIG. 1, the linear bodies 11 of the insertion sheet 1 are protruded from the holes 22 of the cover 2.

  As shown in FIG. 1 and FIG. 2, the plurality of linear bodies 11 are the same or different from each other, but are arranged so as not to be shifted from each other, and there are linear bodies 11 on the right side / left side. The linear body 11 and the insertion hole 10 are arranged so that only the insertion hole 10 exists on the left side / right side opposite to the portion.

  The pair of insertion sheets 1 has a top surface 1b and a bottom surface 1c formed by bending a synthetic resin sheet, such as polypropylene (PP), having a smooth surface, flexibility, and elasticity, along a central folding line 1a. Thus, an insertion hole 10 is formed on the upper surface 1b of the insertion sheet 1 so as to pass through the linear body 11 adjacent to the folding line 1a, and the lower surface 1c is flat without an insertion hole.

  The insertion hole 10 of the insertion sheet 1 is a hole through which the linear body 11 holding the paper sheet 4 to be bound is inserted, and a position corresponding to the binding hole 41 of the paper sheet 4 to be bound shown in FIG. Have been opened.

  A linear body 11 shown in FIG. 3A is inserted into the hole 10 of the insertion sheet 1. The linear body 11 is formed of a smooth and elastic synthetic resin sheet such as polypropylene (PP) or poly-onishimethylene (POM), and is a linear body with both ends rounded to be easily inserted into the hole. The recesses 110 facing each other are formed by rounding out both sides at a certain length from the part.

  In order to plant this linear body 11 in the insertion sheet 1, a hole row made of holes 10, 101, 103 is formed in the upper surface 1 b of the insertion sheet 1. The diameters of the insertion holes 10 and 103 are slightly larger than the width of the linear body 11. As shown in an enlarged view in FIG. 3 (e), the diameter of the engagement hole 101 is slightly larger than the distance between the pair of depressions 110 formed in the linear body 11 and larger than the width of the linear body 11. A cut 102 is formed in a direction orthogonal to the folding line 1a.

  When planting the linear body 11 on the upper surface 1b of the insertion sheet 1, the folded insertion sheet 1 is expanded so that the rear end of the linear body 11 near the recess 110 is seen from the back side of the upper surface 1b. When the recess 110 is inserted into the notch 102 of the hole 101 and the recess 110 is fitted into the hole 101, the linear body 11 is rotated by 90 °, and the recess 110 of the linear body 11 is engaged with the hole 102.

  In this way, after the recess 110 of the linear body 11 is engaged with the engagement hole 101 of the insertion sheet 1, the tip of the linear body 11 is inserted into the hole 10 from the back side of the upper surface 1b, and the upper surface 1b Pull it out to the front side. Then, when the rear end portion of the linear body 11 is inserted into the insertion hole 103 from the upper surface 1b of the insertion sheet 1 and the insertion sheet 1 is folded in half, a cross-sectional view of FIG. As shown in the perspective view of d), the linear body 11 can be mounted so as to be knitted into the insertion sheet 1.

  Instead of the engagement hole 101 having the notch 102 described in the first embodiment, an elliptical hole 104 may be used. As shown in an enlarged view in FIG. 3 (f), the major axis direction of the ellipse is opened in a direction perpendicular to the folding line 1 a, and the minor axis is slightly larger than the distance between the pair of depressions 110 formed in the linear body 11. Is set to be larger than the width of the linear body 11, the linear body 11 is inserted, and when the hollow 110 of the linear body 11 is fitted into the major axis of the ellipse, the linear body 11 is rotated by 90 °. Thus, the depression 110 of the linear body 11 can be engaged with the minor axis of the ellipse.

  Next, the pair of left and right insertion sheets 1 in which the linear body 11 shown in the perspective view of FIG. 3D is implanted are inserted into the bag-shaped storage portion 21 from the bent portion 20 side of the cover 2 and each line is inserted. A procedure for assembling a filing tool in which the body 11 is protruded from each hole will be described.

  First, the extending portion 31 of the protective sheet 3 sewn on the bent portion 20 of the cover 2 serving as a cover is pulled out from the opening of the bag-shaped storage portion 21.

  Insert the insertion sheet 1 with the linear body 11 into the storage part 21 with the upper surface 1b side up, and insert each linear body 11 into the hole 32 formed in the extending part 31 of the protective sheet 3 and then protect it. The extending part 31 of the sheet 3 is inserted into the bag-shaped storage part 21.

  Further, the linear body 11 is inserted into the insertion hole 22 at a corresponding position opened in the bag-shaped storage portion 21, and the linear bodies 11 are respectively pulled out to the front surface of the cover 2. When the same assembly operation is performed in the bag-shaped storage portion 21 on the opposite side across the bent portion 20 and the mounting of the pair of left and right insertion sheets 1 is completed, as shown in the perspective view of FIG. The filing tool of one embodiment can be completed.

  When binding paper sheets to the filing tool, the cover 2 is opened as shown in the perspective views of FIGS. When binding a bundle of paper sheets together, out of the linear bodies 11 protruding along the bent portion 20 of the cover, the bundle of paper sheets is attached to the linear body 11 protruding from the right or left cover 2. Insert 4 binding holes. Then, the paper sheet can be bound by inserting the tip of the linear body 11 protruding upward from the paper sheet 4 into the hole 22 of the cover 2 on the opposite side so as not to be loosened.

  When the paper sheet is bound in two, as shown in FIG. 4, the paper sheet 4 divided into two is bound to the left and right linear bodies 11 protruding along the bent portion 20 of the cover. Each of the holes 41 is inserted. Then, the leading ends of both linear bodies 11 protruding upward from the left and right paper sheets 4 are inserted through the binding holes 41 of the opposite paper sheet 4 so as not to be loosened respectively. Thus, the paper sheets 4 can be bound as shown in the cross-sectional view of FIG.

  At this time, since each linear body 11 inserted into the hole 10 of the insertion sheet 1 enters between the two-fold insertion sheet 1 having good slipperiness, the linear body 11 can be smoothly inserted without resistance. it can.

  When the cover 2 in which the paper sheets 4 are bound in this manner is folded, the cover 2 can be folded as shown in the sectional view of FIG. 4D through the process of FIG.

  When the new linear body 11 is attached to the cover cover 2, as shown in the cross-sectional view of FIG. 3C and the perspective view of FIG. However, the cover 2 is folded and stored, and the linear body 11 is deformed over time as a result of use, and as shown in the perspective view of FIG. It changes into a shape.

  In this filing tool, the hole 10 of the insertion sheet 1, the hole 22 of the cover 2, the hole 32 of the protective sheet 3, and the binding hole 41 of the paper sheet 4 are configured to be shared by the linear body 11. Yes. Therefore, when deleting a paper sheet of an arbitrary page or adding a paper sheet to an arbitrary page, when the corresponding page is opened and all the linear bodies 11 are extracted, the paper is caused by the linear bodies 11 rising to the left and right. Since the leaf 4 is stably held, it is possible to easily add and delete paper sheets.

  In the first embodiment described above, the paper sheet 4 having four binding holes is illustrated, but the number of binding holes may be arbitrarily set according to the paper sheets to be bound.

  In the filing tool of the present invention, when the number of the linear bodies 11 is larger than necessary with respect to the number of holes of the paper sheets to be bound, the unnecessary linear bodies 11 are removed from the insertion sheet 1 or the unnecessary linear bodies are removed. If the body 11 is hidden under the insertion sheet 1 on the opposite side, it is easy to cope with a change in use.
