This application is a 35 U.S.C. 371 National Phase Entry Application from PCT/JP2020/011848, filed Mar. 17, 2020, which claims priority to Japanese Patent Application No. JP 2019-073949 filed Apr. 9, 2019, the disclosures of which are incorporated herein in their entirety by reference, and priority is claimed to each of the foregoing.
The present invention relates to a staple and a connecting staple for holding and binding two portions (a first end-side portion and a second end-side portion) on both sides of a cord wound around a to-be-bound object.
In the related art, in the cultivation of fruit trees such as grapes, an induction binding machine is used so as to induce and grow branches of the fruit tree to a support post and the like (for example, refer to the induction binding machine disclosed in NPL 1).
When performing an induction operation with the induction binding machine, a cord such as a rubber tube is first wound around a to-be-bound object and a staple is struck so as to hold two portions (a first end-side portion of the cord and a second end-side portion on an opposite side to the first end-side portion) on both sides of the cord by the induction binding machine. Thereby, the cord is held and fixed by the staple, so that the to-be-bound object can be bound by the cord.
For the induction binding machine of the related art, for example, a staple 100 as shown in
However, as shown in
It is therefore an object of the present invention to provide a staple and a connecting staple capable of stabilizing a position of a cord and strongly holding a held cord.
The present invention has been made in view of the above situations, and may adopt following configurations, for example.
In the configuration of (1), the crown part is provided between the pair of leg parts, and the crown part is formed with the mountain portion bent inwardly. According to this configuration, when binding a cord with the staple, the two cords induced between the pair of leg parts can be separated in two directions. Since the two portions, i.e., the first end-side portion and the second end-side portion on both sides of the cord can be each held by the separate leg parts, the form at the time of the holding is likely to be stable, and the held cord can be strongly held.
In addition, in the configuration of (2), the leg parts and the crown part have the holding portions provided to face each other so as to sandwich the cord. According to this configuration, since the cord can be sandwiched and held by the holding portions, the held cord can be strongly held. For example, in the staple of the related art as shown in
In addition, in the configuration of (3), the tip ends of the leg parts are provided with the introduction portions that are expanded toward tip end directions. According to this configuration, when pulling the cord toward the inner side of the staple, the pulling can be facilitated using the introduction portions. In addition, in the staple of the related art as shown in
Further, in the configuration of (13), it is possible to obtain the connecting state having the plurality of staples connected to each other.
Embodiments of the present invention will be described with reference to the drawings.
A staple 10 according to the present embodiment is to hold and bind two portions (a first end-side portion 20a of a cord 20 and a second end-side portion 20b on an opposite side to the first end-side portion 20a) on both sides of a cord 20 wound around a to-be-bound object. The first end-side portion 20a is a portion closer to one end-side than a middle portion of the cord 20 wound around the to-be-bound object, and the second end-side portion 20b is a portion closer to the other end-side than the middle portion of the cord 20 wound around the to-be-bound object.
The staple 10 is used for an induction operation in the cultivation of fruit trees such as grapes, for example. Specifically, as shown in
When performing the induction operation, a plurality of to-be-bound objects (the branch 23, the support post 21, the wire 22 and the like) is first bundled and wound with the cord 20 such as a rubber tube, and the staple 10 is struck using the induction binding machine so as to hold the two portions (the first end-side portion 20a and the second end-side portion 20b) on both sides of the cord 20. Then, as shown in
As shown in
Note that, in the present embodiment, although not particularly shown, the ejection port of the induction binding machine may be provided with a guide part for dividing and guiding the two cords 20 to both sides of the staple 10. That is, the guide part is provided, so that the two portions (the first end-side portion 20a and the second end-side portion 20b) on both sides of the cord 20 can be divided and guided to both sides of a mountain portion 12b, which will be described later.
As shown in
The pair of leg parts 11 is provided on both sides of the staple 10 so as to continue from both ends of the crown part 12. Each of the pair of leg parts 11 has a second holding portion 11a continuing to the crown part 12 and an introduction portion 11b continuing to the second holding portion 11a. Therefore, the pair of leg parts 11 has a pair of second holding portions 11a and a pair of introduction portions 11b.
The leg part 11 has a tip end-bent portion 13 between (connection portion) the second holding portion 11a and the introduction portion 11b. The leg part 11 has a shape bent at an obtuse angle at the tip end-bent portion 13. For this reason, the leg part 11 has a substantially inverted ‘V’ shape, as seen from the front.
The second holding portion 11a is a portion formed linearly and is a portion for sandwiching the cord 20 by cooperating with the crown part 12.
In addition, the introduction portion 11b is a portion provided at a tip end of the leg part 11, and is a portion for facilitating pulling of the cord 20 toward an inner side of the staple 10. In a state before clinch, the pair of introduction portions 11b is expanded toward tip end directions. The introduction portions 11b expanded in this way are provided, so that an entry of the staple 10 for introducing the cord 20 is largely widened. As a result, the cord 20 can be easily inserted to the inner side of the staple 10. In addition, the tip ends of the leg parts 11 are faced outward, so that the cord 20 is difficult to be caught at burrs of the tip ends.
Note that, as shown in
Further, in the present embodiment, as shown with the dashed-dotted line in
The crown part 12 connects the pair of leg parts 11. The crown part 12 has a pair of first holding portions 12a each continuing to each of the pair of leg parts 11 and a mountain portion 12b provided between the pair of first holding portions 12a.
The first holding portion 12a is a portion formed linearly and is a portion for sandwiching the cord 20 by cooperating with the second holding portion 11a of the leg part 11. A length of the first holding portion 12a is substantially the same as a length of the second holding portion 11a of the leg part 11.
The first holding portion 12a of the crown part 12 and the second holding portion 11a of the leg part 11 have a shape bent at an acute angle at a leg-bent portion 14, and face each other so as to sandwich the cord 20. Specifically, the leg-bent portion 14 having a shape bent at an acute angle toward an outer side of the staple 10 is provided between (connection portion) the first holding portion 12a and the second holding portion 11a.
As shown in
Note that, the bending R (curvature radius) on the inner side of the leg-bent portion 14 is preferably formed smaller than a diameter of the cord 20. The bending R (curvature radius) on the inner side of the leg-bent portion 14 is made small, so that a gap is difficult to form between the second holding portion 11a of the leg part 11 and the first holding portion 12a of the crown part 12 at the time of clinching. As a result, it is possible to prevent the clinched cord 20 from sliding.
In addition, the mountain portion 12b bends the middle portion of the crown part 12 so as to protrude inwardly. In other words, the mountain portion 12b bends toward the end portion directions of the leg parts 11. The mountain portion 12b is provided, so that the crown part 12 has a substantially inverted ‘V’ shape, as seen from the front.
The mountain portion 12b is provided so as to separate the two portions (the first end-side portion 20a and the second end-side portion 20b) on both sides of the cord 20 wound around the to-be-bound object. Specifically, as shown in
The pocket P is provided between the second holding portion 11a and the first holding portion 12a facing each other. More specifically, the pocket P is provided in a region surrounded by the extension line (the dashed-dotted line in
Further, the mountain portion 12b is provided to the crown part 12, so that the cord 20 can be stably held even after binding. Specifically, as shown in
Specifically, as seen in the upper and lower direction shown in
Note that, the mountain portion 12b is preferably at a right angle or an obtuse angle, and more preferably in a range of 90° to 130°. The mountain portion 12b is at such angle, so that the staple 10 after binding is resistant to deformation and it is also easy to obtain the effect resulting from the tilting of the staple 10.
In addition, since the pockets P for holding the cord 20 are formed on both sides of the staple 10 and a pocket exit A is provided between the pockets P on both sides, even when the cord 20 is pulled toward both the left and right sides (arrow direction in
Note that, in a staple 100 of the related art as shown in
As described above, the staple 10 of the present embodiment has the crown part 12 between the pair of leg parts 11, and the crown part 12 is formed with the mountain portion 12b bent inwardly. According to this configuration, when binding the cord 20 with the staple 10, it is possible to divide and bind the two portions (the first end-side portion 20a and the second end-side portion 20b) on both sides of the cord 20 on both sides of the mountain portion 12b. In this way, since the two cords 20 can be separated from each other and an appropriate load can be applied to the cords 20 by each of the leg parts 11 of the staple 10, positions of the two cords 20 become stable and the held cords 20 can be strongly held.
In addition, in order to sandwich the cord 20, the second holding portion 11a of the leg part 11 and the first holding portion 12a of the crown part 12 are provided to face each other. According to this configuration, it is possible to sandwich and hold the cord 20 by the second holding portion 11a and the first holding portion 12a. When the cord 20 is sandwiched by the second holding portion 11a and the first holding portion 12a, a gap is difficult to form between the leg part 11 and the crown part 12 after clinch, so that the held cord 20 can be strongly held.
Further, the tip ends of the leg parts 11 are provided with the introduction portions 11b that are expanded toward the tip end directions. According to this configuration, when pulling the cord 20 toward the inner side of the staple 10, it is possible to facilitate the pulling by using the introduction portions 11b. In addition, in the staple 100 of the related art as shown in
Note that, the staple 10 of the above embodiment is formed using a wire rod having a section as shown in
In addition, as shown in
Of course, the staple 10 may also be formed using a wire rod having a circular section without providing the flat surface 15 or the unevenness shape 15a.
In addition, in the above embodiment, the second holding portion 11a and the first holding portion 12a have been described as linearly extending. However, the present invention is not limited thereto. For example, one or both of the second holding portion 11a and the first holding portion 12a may be formed in a curved shape.
Further, in the above embodiment, the case where the leg-bent portion 14 is at an acute angle has been described. However, the present invention is not limited thereto. For example, the leg-bent portion 14 may be at a right angle or an obtuse angle.
Further, in the above embodiment, the mountain portion 12b is formed by bending the middle portion of the crown part 12 so as to protrude inwardly. However, the shape of the mountain portion 12b described in the embodiment is just exemplary, and other shapes can also be adopted. For example, the mountain portion 12b may be formed by denting the middle of the crown part 12.
Further, the mountain portion 12b may be provided so that the middle portion of the crown part 12 is inwardly curved, instead of bending the middle portion of the crown part 12 so as to protrude inwardly. In this case, the curved mountain portion 12b is provided, so that the crown part 12 has a substantially inverted ‘U’ shape, as seen from the front.
