Description

  The present invention relates to a document binding tool for binding and organizing and storing documents and the like.

  Conventionally, a document binding tool called a file has been used for binding and organizing and storing documents and booklets. This document binding tool basically includes a cover that surrounds the document, It is comprised by the binding tool main body provided inside. In fixing the binding tool body to the cover, for example, as shown in Patent Document 1, a cover ("cover 11" in Patent Document 1) and a binding tool body ("Binding Tool" in Patent Document 1). 12 ") and a rivet is fixed to the through-holes drilled in both sides.

  However, as shown in Patent Document 1, when the binding tool body is fastened to the cover with a rivet, an extra component called a rivet is inevitably required, and a dedicated tool for caulking the rivet, or Since dedicated equipment is required, there is a problem that the manufacturing cost is increased. Further, when using a rivet, a troublesome work of caulking the rivet is required, so that production time and labor are inevitably excessive. Further, when the rivet is fastened, the head of the rivet appears on the surface of the cover, so that it may not look good and the layout of the cover surface may be limited in design. In addition, when a large force is applied to the binding tool body when attaching or detaching a document, the force is concentrated in a narrow area of the rivet head. Therefore, if the cover itself does not have sufficient strength, There is also a problem of being pulled out of the cover.

  On the other hand, as a method for fixing the binding tool main body to the cover, for example, as shown in Patent Document 2, the cover ("File 29" in Patent Document 2) is attached to the binding tool body ("Binding Tool 20" in Patent Document 2). ")" Is also used for ultrasonic welding.

  However, even in fixing by ultrasonic welding shown in Patent Document 2, it is an absolute requirement to provide dedicated equipment. In addition, when performing ultrasonic welding, there is a problem that the material of the cover and the binding tool main body is limited. That is, when performing ultrasonic welding, both the cover and the binding body need to be made of synthetic resin. For example, when the cover is made of paper for the purpose of reducing costs, The method cannot be adopted.

  Furthermore, there is also a method of fixing the binding tool body to the cover with an adhesive. However, if the adhesive is used, the adhesive will peel off if the document binding tool must be stored in a place where the temperature becomes high or low. There may be a problem that the main body of the binding device comes off from the main body.

  Next, embodiments of the present invention will be described with reference to the drawings. 1 is a developed view of a cover of a document binding tool, FIG. 3 is a perspective view of a binding tool body of the document binding tool, FIG. 4 is a perspective view of the document binding tool, and FIG. 5 is a cross-sectional view taken along line AA in FIG. . Here, the document binding tool according to the present invention is roughly constituted by a cover A, a tab portion 13 provided to extend on an edge of the cover A, and a binding body B attached to the cover A.

  As shown in the developed view of FIG. 1, the cover A is formed by cutting a relatively thin paperboard whose surface is coated with a polypropylene film into a rectangular shape. In order to be able to be folded, two folds 11 and 11 are provided in parallel in a straight line with the gusset portion 10 in between. A tab portion 13 is formed in an extended shape at one end edge in the longitudinal direction of the cover A (left end edge in FIG. 1) with a folding line 12 therebetween. In addition, a long hole 14 (insertion hole) having a width of several millimeters is formed on the tab portion 13 adjacent to the folding line 12 (on the folding line) so as to follow the folding line 12. A pair of through-holes 15 and 15 are opened at a position slightly outside the long hole 14 of the portion 13. In addition, an adhesive margin 16 is formed at the leading edge of the tab portion 13. The adhesive margin 16 is formed to have only a small width from the inner edge of the tab portion 13 toward the center portion of the tab portion 13. Therefore, when the tab portion 13 is bent at the folding line 12 and an adhesive is applied to the adhesive margin 16, a non-adhesive portion, in other words, a bag-like space portion is formed inside the cover A and inside the adhesive margin 16. become. In addition, the length of the longitudinal direction of the long hole 14 is set slightly longer than the length of the longitudinal direction of the binding tool main body B described later.

  The binding tool body B is integrally formed of an elastic plastic material such as polypropylene. As shown in FIG. 3, the rectangular seat plate 1 and the long side of the seat plate 1 are thin. A rectangular back plate portion 4 provided continuously with a portion 3 interposed therebetween, and a rectangular adherend plate 6 provided continuously with a thin portion 5 interposed on the other long side of the back plate portion 4. Yes. Thus, since the thin portions 3 and 5 are provided on both side edges of the back plate portion 4 provided between the seat plate 1 and the adherend plate 6, the adherend plate 6 can be refracted with respect to the seat plate 1. It has become. The upper surface of the seat plate 1 is provided with the binding shafts 2 and 2 protruding upward from the seat plate 1 at a predetermined interval. Engagement portions 2a and 2a are formed. Further, the adherence plate 6 is provided with engagement holes 7 and 7 for engaging and disengaging with the engagement portions 2a and 2a of the seat plate 1, and these engagement holes 7 and 7 are shown in FIG. As shown, the inner diameter increases as it goes upward. In addition, the width | variety of the backplate part 4 is set to the length substantially corresponded with the height of the binding axes 2 and 2 of the seat board 1. FIG. Therefore, when the adherend plate 6 is refracted with respect to the seat plate 1, the engagement holes 7 and 7 of the adherend plate 6 face the binding axes 2 and 2 of the seat plate 1, and the engagement holes 7 and 7 are formed. It can be engaged with and disengaged from the distal ends of the binding shafts 2 and 2. Further, a rib 8 is formed upright on the upper surface of the seat plate 1 in the vicinity of the thin portion 3 along the thin portion 3, and the back plate is opposed to the side surface of the rib 8. A rib 9 projects from the portion 4.

  Next, a procedure for fixing the binding device main body B shown in FIG. 3 to the cover A shown in FIG. 1 will be described. First, the tab portion 13 is bonded to the cover A. Specifically, after applying an adhesive to the glue margin 16 of the tab portion 13 extending from the cover A, the tab portion 13 is bent inward from the folding line 12 and the glue margin 16 is adhered to the inner surface of the cover A. At this time, the long hole 14 is located inside the side edge of the cover A. Further, since the margin 16 is limited to a predetermined width near the tip edge of the tab portion 13, a bag-like non-adhesive portion is formed between the tab portion 13 excluding the margin 16 and the cover A. Thus, the long hole 14 can be slightly expanded in the vertical direction. Therefore, while spreading the long hole 14, the seat plate 1 of the binding body B is inserted into the long hole 14, and the binding shafts 2, 2 of the seat plate 1 are inserted into the through holes 15, 15 opened in the tab portion 13. Then, the binding shafts 2 and 2 are protruded upward from the through holes 15 and 15. Thereby, as shown in FIG. 4, the binding body B is fixed to the cover A. When the binding tool body B is fixed to the cover A, the binding tool body B is restricted in movement by fitting the binding shafts 2 and 2 into the through holes 15 and 15, and the seat plate The one long side of 1 is exposed from the long hole 14 and is maintained in a stable state without being laterally displaced. As described above, according to the present invention, in order to fix the binding tool body B to the cover A, it is only necessary to insert the binding tool body B into the long hole 14 while expanding the long hole 14 of the cover A. There is no need to use a rivet or the like as in the prior art, and the mounting operation can be greatly simplified, and the manufacturing cost can be reduced. Further, since it is not necessary to use a technique called ultrasonic welding, for example, it is possible to form the cover A with paper and the binding tool body B with resin such as polypropylene.

  Incidentally, the document binding tool in the present embodiment is used as follows. That is, as shown in FIG. 4, in a state where the cover A is expanded and the adherend plate 6 of the binding tool body B is not closed, a document 20 having a punch hole previously formed is prepared, The punch hole of the document 20 is inserted into the binding axes 2 and 2 of the binding tool body B. Next, the back plate portion 4 is erected. When the back plate portion 4 is erected, the leading edge of the rib 9 of the back plate portion 4 comes into contact with the side surface of the rib 8 of the seat plate 1 so that the back plate portion 4 becomes the seat plate. It is designed to be at right angles to 1. In this state, when the adherend plate 6 is further refracted toward the seat plate 1, the engagement holes 7 of the adherend plate 6 are aligned with the upper ends of the binding shafts 2 and 2. Then, the engagement holes 7 and 7 of the adherend plate 6 are engaged with the engagement portions 2 a and 2 a of the binding shafts 2 and 2 of the seat plate 1 so as to push the adherend plate 6 toward the seat plate 1. In addition, the part with the largest outer diameter of the engaging parts 2a, 2a formed in the inverted conical shape is formed slightly larger than the part with the smallest inner diameter of the engaging holes 7, 7. Therefore, when the adherend plate 6 is pressed by hand, the maximum diameter portion of the inverted conical shape and the inner diameter of the engagement holes 7 and 7 are expanded by the elasticity of the plastic material, and the adherend plate 6 is extended to the upper ends of the binding shafts 2 and 2. Can be easily engaged. By doing so, as shown in FIG. 6, the document 20 is bound to the document binding tool. In this document binding tool, since the seat plate 1 of the binding device main body B is sandwiched between the tab portion 13 and the cover A and contacts the tab portion 13 and the cover A over a wide area, the external force applied to the seat plate 1 is dispersed. The For this reason, even if a relatively thin cover is used, external force concentrates on the rivet as in the case of riveting, and there is no risk that the cover will break and the binding body B will fall off. Holds.

  In the developed view shown in FIG. 1, an example is shown in which the long hole 14 of the cover A is formed so that its lateral width protrudes only from the folding line 12 toward the tab portion 13, but is not limited thereto. As shown in FIG. 8, both sides of the folding line 12, that is, the lateral width of the long hole 14 may be formed so as to protrude toward the cover A side. In this way, the lower surface of one long side of the seat plate 1 is positioned in the long hole 14. Therefore, when attaching / detaching the adherend plate 6 to / from the binding shafts 2 and 2, even if an external force that tilts the seat plate 1 in the width direction is applied, no external force is applied directly to the cover A, and the edge of the cover A Inconveniences such as bending or wrinkles can be prevented. Moreover, when inserting the binding tool main body B in the long hole 14 of the cover A, there also exists an advantage that the opening | mouth expands more.

  Next, a second embodiment of the present invention will be described with reference to FIGS. In the following embodiments, the same components as those in the above-described embodiment will be described with the same reference numerals. In the document binding device of this embodiment, the binding device main body B is fixed to the inner surface of the upper edge of one side of the cover A as shown in FIG. That is, the cover A of the document binding tool is, as shown in the developed view of FIG. 9, a tab portion 13 with a folding line 12 at an upper edge portion on one side of the cover A as a boundary. A long hole 14 (insertion hole) having a predetermined width is formed on the folding line 12. In addition, a pair of through holes 15 and 15 are formed at positions slightly outside the long hole 14 of the tab portion 13, and an adhesive margin 16 is formed at the tip edge of the tab portion 13.

  Then, as a procedure for fixing the binding tool body B to the cover A, first, after applying an adhesive to the glue margin 16, the tab portion 13 is folded inward from the folding line 12, and the glue margin 16 is secured to the inner surface of the cover A. Adhere to. At this time, since the adhesive margin 16 is provided only in a predetermined width, a bag-like non-adhesive portion to which no adhesive is applied is formed on the inner side of the cover A and the inner side of the tab portion 13. Next, while expanding the long hole 14 in the vertical direction, the seat plate 1 of the binding device main body B is inserted from the long hole 14 so that the seat plate 1 is positioned between the cover A and the tab portion 13 and the binding device main body B. Are protruded from through-holes 15 and 15 formed in the tab portion 13. Also in this case, when the binding tool main body B is fixed to the cover A, the movement of the binding shafts 2 and 2 is restricted by the through holes 15 and 15. A stable state is maintained without lateral displacement with one long side exposed from the long hole 14. In the document binding tool shown in this embodiment, as shown in FIG. 11, a vertically long document 20 in which punch holes are formed in advance on the upper side can be bound with one touch. In the document binding tool shown in this embodiment, the seat plate 1 comes into contact with the tab portion 13 and the cover A over a wide area, so that the external force is dispersed and hardly damaged.

  FIGS. 12 to 15 show a third embodiment of the present invention. The document binding device of this embodiment has a gusset portion 10 on the inner surface of the cover A as shown in FIG. Along the way. That is, as shown in FIG. 12, the cover A of this document binding tool forms a tab portion 13 with a folding line 12 at the edge on the right side in the longitudinal direction of the cover A, and the tab portion A cut 17 (insertion hole) is formed at the tip edge of 13. In addition, a pair of through holes 15 and 15 are formed at a position slightly inward from the notch 17 of the tab portion 13, and a paste margin 16 having a predetermined width is formed so as to surround the notch 17 and the through holes 15 and 15. . The width of the tab portion 13 in this embodiment is set to be approximately the same as the width of the half surface of the cover A, specifically, the surface of the cover A adjacent to the tab portion 13. Therefore, when the tab 13 is bent along the folding line 12, the side edge of the tab portion 13 is positioned along the gusset portion 10 of the cover A.

  Then, as a procedure for fixing the binding tool body B to the cover A, first, after applying an adhesive to the glue margin 16, the tab portion 13 is folded inward from the folding line 12, and the glue margin 16 is secured to the inner surface of the cover A. Adhere to. At this time, since the adhesive margin 16 is provided only in a predetermined width, a bag-like non-adhesive portion to which no adhesive is applied is formed on the inner side of the cover A and the inner side of the tab portion 13. Next, while expanding the notch 17 in the vertical direction, the seat plate 1 of the binding tool body B is inserted from the notch 17 so that the seat plate 1 is positioned between the cover A and the tab portion 13, and the binding tool body B Are protruded from through-holes 15 and 15 formed in the tab portion 13. Also in this case, when the binding tool body B is fixed to the cover A, the movement of the binding shaft body 2 is restricted by the through holes 15 and 15 and the seat plate 1 is moved. A stable state is maintained without lateral displacement. And in the document binding tool shown in this embodiment, as shown in FIG. 15, a vertically long document 20 in which punch holes are previously formed in the side portions can be bound with one touch. In the document binding tool shown in this embodiment, the seat plate 1 comes into contact with the tab portion 13 and the cover A over a wide area, so that the external force is dispersed and hardly damaged.

  In the embodiment, the example in which the adhesive is applied to the entire adhesive margin 16 of the tab portion 13 has been described. However, it is not always necessary to apply the adhesive to the entire adhesive margin. For example, the adhesive is partially applied to the adhesive margin 16. You may make it do. In short, when an adhesive is applied to the glue margin 16 and adhered to the inside of the cover A, a bag-like non-adhesive portion may be formed on the inside of the cover A and the inside of the tab portion 13. .
