FIG. 1 is a schematic perspective view of the binding tool according to the present embodiment. In this figure, the binding tool 10 includes a base 11 fixed to the inner surface side of a predetermined cover body and two sets of binding legs 12 provided on the base 11. The base 11 has a plate-like portion 13 having a substantially oval shape in plan view located on the inner surface of the cover body, and a pair located on the upper surface of the plate-like portion 13 so as to be connected to both ends of the plate-like portion 13 in the short width direction. The movable piece portions 14 and 15 are configured. Here, the movable piece portions 14 and 15 are formed such that the center positions of the inner ends 14A and 15A are notched in a concave shape, and the push button 16 positioned in the region formed by the notches is provided. By performing the pressing operation, as shown in FIG. 2, the inner ends 14 </ b> A and 15 </ b> A are rotatably provided upward. In addition, since the opening operation | movement of the binding leg 12 by the push button 16 is not the summary of this invention, detailed illustration description is abbreviate | omitted here.
[0010]
As shown in FIGS. 4 to 6, the binding foot 12 is an axial first binding foot forming body that stands up from two positions in the longitudinal direction (the direction orthogonal to the paper surface in FIG. 4) of one movable piece portion 14. 20 and a shaft-like second binding foot forming body 21 standing up from the other movable piece 15 corresponding to the first binding foot forming body 20. The first binding foot forming body 20 is provided with a length that ends at a position where the upper end side is slightly curved toward the second binding foot forming body 21. On the other hand, the second binding foot forming body 21 is connected to the base 23 having a length shorter than the length of the first binding foot forming body 20 and the distal end side, that is, the upper end side of the base 23, and is connected to the first binding foot forming body 21. It is comprised by the displacement part 24 curved so that it might face | match with the front-end | tip of the binding leg formation body 20 of this.
[0011]
As shown in FIG. 6, the upper end side of the base portion 23 is provided with connecting pieces 25 on both the left and right sides. A concave portion 26 is formed between the connecting pieces 25, and is slightly below the bottom surface of the concave portion 26. Thus, a hollow portion 27 (see FIGS. 4 and 5) is formed.
[0012]
On the other hand, a connecting piece 30 positioned in the recess 26 is formed on the lower end side of the displacement portion 24, and the pin 32 is connected to each connecting piece 25, 30 in a state where the connecting piece 30 is positioned in the recess 26. Accordingly, the displacement portion 24 is connected to the base portion 23 so as to be bendable. Further, on the base end (upper end in FIG. 5) side of the connecting piece 30 in the displacement portion 24, a hollow portion 35 that is continuous with the hollow portion 27 on the base portion 23 side described above is formed. And each end part side of the spring 36 supported by the outer periphery of the said pin 32 is arrange | positioned so that it may extend to each hollow part 27,35. Here, as shown in FIG. 4, the front end surfaces of the first binding foot forming body 20 and the displacement portion 24 are inclined surfaces 20A and 24A, respectively. The spring 36 is always kept in close contact with the urging force of the spring 36, so that a closed loop is always formed by the base 11 and the binding foot 12.
[0013]
In the above configuration, when binding the document P (see FIG. 3), as shown in FIG. 2, the push button 16 is pressed to form a binding space similar to that found in a normal binding tool. be able to. Then, when it is desired to easily bind without performing such an operation, the edge P1 of the document P may be abutted downward from above with respect to the displacement portion 24 as shown in FIG. As a result, the displacement portion 24 bends at the position on the distal end side of the base portion 23 against the urging force of the spring 36. Then, by inserting the first binding foot forming body 20 into the binding hole P2 formed in the document P, the displacement portion 24 returns to the closed loop forming position in the initial posture, and the binding can be completed.
[0014]
Therefore, according to such an embodiment, the document can be bound by an external force using the document abutting force without performing a special operation for opening the binding foot 12, which is very simple. In addition, an effect that binding can be performed quickly is obtained.
[0015]
In the above-described embodiment, the structure in which the displacement portion 24 is biased to the position where the closed loop is formed by the tension of both ends of the spring 36 is adopted. However, the present invention is not limited to this, and the entire base portion 23 is formed. It can replace with the structure etc. which are formed so that it may become a hollow cylinder shape, and a tension coil spring is interposed between the back surface side of the base 11, and the displacement part 24. In short, the present invention only needs to have a structure in which the displacement portion 24 can always return to the initial posture in which a closed loop is formed. Therefore, it is also possible to employ a single binding foot forming body 21 using elasticity that allows a bending operation while allowing a returning operation to the initial posture without using the spring 36.
[0016]
【The invention's effect】
As described above, according to the present invention, either one of the first and second binding foot forming bodies is provided so as to be able to bend, and is bent when an external force is applied in a posture in which the closed loop is formed. Since the binding space is formed, an external force is applied to the binding foot forming body that can be bent by abutting the edge of the document against the binding foot forming body, whereby the binding foot forming body is bent. Thus, a space can be formed between the butted ends of the other binding foot forming body. Therefore, by moving the document so that the binding foot forming body passes through the binding hole of the document, binding can be performed without performing any special operation for forming the binding space for the document.
[0017]
In addition, since the binding foot forming body that can be bent is provided by providing a displacement portion on the distal end side of the base portion, it is possible to perform a bending operation only by giving a joint function to the existing shape of the binding foot forming body. it can. In addition, since the displacement portion is set to be kept in the closed loop position using the urging means, by setting the urging force of the urging means appropriately, the unintended bending motion is avoided and the document is dropped. Can also be prevented.
[0018]
In addition, since the spring is disposed in a hollow portion provided in the connection region between the base and the displacement portion, the displacement portion is maintained in a closed loop position, so that the presence of the spring can be seen from the outside. And the appearance of the appearance can be kept good.
