[0013] First, in the present disclosure, as shown in FIG. 1, the longitudinal direction of the passing tool 100 is defined as the first direction X, the direction perpendicular to the first direction X is defined as the second direction Y, and the direction perpendicular to the first direction X and the second direction Y is defined as the third direction Z for explanation. Here, the side where the passing tool 100 in the first direction X is first inserted into the bag-shaped strip passage portion 300 (see FIG. 6) is taken as the front side, designated as the front side X1, and the side where it is inserted last into the bag-shaped strip passage portion 300 is taken as the rear side, designated as the rear side X2.

[0014] Also, the second direction Y is the vertical direction here, with the upper side designated as the upper side Y1 and the lower side designated as the lower side Y2. Further, for the third direction Z, one side is described as the front side Z1 and the other side as the back side Z2. Note that the strip 200 (see FIG. 4) referred to in the present disclosure can be similarly applied to any strip-shaped or string-shaped object as long as the first direction X is longer than other directions.

[0015] As shown in Figures 1 and 2, the pass-through 100 comprises, in order from the front side X1 in the first direction X, a tip portion 1, a base portion 2, a locking portion 3, and a ring portion 4. Thus, the base portion 2 is connected to the rear side X2 of the tip portion 1. The locking portion 3 is connected to the base portion 2 on the side opposite to the tip portion 1, the rear side X2. The tip portion 1, the base portion 2, and the locking portion 3 are formed, for example, by integral molding. The tip portion 1, the base portion 2, and the locking portion 3 are formed, for example, by polyamide. The ring portion 4 is detachably locked to the side of the locking portion 3 opposite to the base portion 2, i.e., the rear side X2. Thus, the ring portion 4 is not formed integrally with the tip portion 1, the base portion 2, and the locking portion 3. The ring portion 4 is formed from, for example, ABS resin (acrylonitrile, butadiene, and styrene copolymer synthetic resin).

[0016] The rigidity of the tip portion 1 is higher than that of the base portion 2. The tip portion 1 is formed by a conical portion 12, for example, with its apex at the front side X1, and a cylindrical portion 11, for example, connected to the rear side X2 of the conical portion 12. The tip portion 1 has a central axis in the first direction X. Note that these shapes are just examples, and other cylindrical shapes other than cylindrical, and other conical shapes other than conical, can be formed similarly and the same effect can be obtained. However, from the viewpoint of usability and durability, cylindrical and conical shapes are considered appropriate.

[0017] The base portion 2 is formed in a plate shape having planes 20 parallel to the first direction X and the second direction Y on its front side Z1 and back side Z2, respectively, and is flexible in the third direction Z. That is, the base portion 2 is configured to bend and curve in the third direction Z on its front side Z1 and back side Z2. The locking portion 3 has a first through hole 31 that penetrates in the second direction Y. The ring portion 4 has a second through hole 41 that penetrates in the third direction Z, and a dividing portion 42 that divides the second through hole 41. The dividing portion 42 of the ring portion 4 allows the second through hole 41 of the ring portion 4 to be attached to and detached from the first through hole 31 of the locking portion 3.

[0018] Here, the lengths of each part of the through-device 100 are shown. These lengths are examples and are not limiting, but are shown to make it easier to understand the approximate size when using the through-device 100 of this disclosure in general. The length W1 of the tip portion 1 in the first direction is about 15 mm. The length T1 of the columnar portion 11 of the tip portion 1 in the second direction Y is about 4 mm, and the length H1 in the third direction Z is also about 4 mm. Here, since the columnar portion 11 of the tip portion 1 is formed as a cylinder, the lengths T1 and H1 are formed to be approximately the same length.

[0019] The length W2 of the base 2 in the first direction is approximately 80 mm, the length T2 in the second direction Y is approximately 4 mm, and the length H2 in the third direction Z is approximately 1 mm. The base 2 is formed in a plate shape with a flat surface 20, and since the length H2 in the third direction Z is very short compared to other parts, it can have sufficient flexibility in the third direction Z. In addition, since the flat surface 20 has a length T2 in the second direction Y, it is large enough for a person to grasp the threading tool 100 by hand and move it inside the bag. Furthermore, since the length T2 in the second direction Y is kept to a minimum for the operation of the threading tool 100, it is possible to easily pass it through the bag-shaped belt threading section 300, which will be described later, even if the size of the belt threading section 300 is small.

[0020] Furthermore, since the tip portion 1 and base portion 2 are formed to such sizes, and the rigidity of the tip portion 1 is greater than that of the base portion 2, when moving the pass-through tool 100 into the bag-shaped belt pass-through portion 300, the rigidity of the tip portion 1 allows the pass-through tool 100 to advance easily.

[0021] The length W3 of the locking portion 3 in the first direction is approximately 25 mm, the length T3 in the second direction Y is approximately 3 mm, and the length H3 in the third direction Z is approximately 3 mm. Since the length H3 of the locking portion 3 in the third direction Z is larger than the length H2 of the base portion 2 in the third direction Z, the first through hole 31 can be easily formed.

[0022] The length W4 of the ring portion 4 in the first direction is approximately 18 mm, the length T4 in the second direction Y is approximately 7 mm, and the length H4 in the third direction Z is approximately 2 mm. The ring portion 4 only needs to be large enough to form a second through-hole 41 that can penetrate the first through-hole 31. However, as will be explained later, the ring portion 4 remains inside the bag-shaped band-passing portion 300 together with the band 200, so if it is too large it will feel unnatural, and if it is too small it will reduce durability and operability, so it should be set appropriately.

[0023] Such a fastener 100 is for installing a belt 200 inside a bag-shaped belt fastener 300. The belt 200 installed using the fastener 100 will now be described. As shown in Figure 4, the belt 200 has a first hook portion 201 at one end (front side X1) in the longitudinal direction (first direction X) and a second hook portion 202 at the other end (rear side X2). The first hook portion 201 and the second hook portion 202 are formed by stitched portions 210 that are sewn to a part of both ends of the belt 200 in a loop shape.

[0024] In this example, the first hook portion 201 and the second hook portion 202 are formed by the sewing portion 210, but other configurations are also acceptable as long as they form a loop and allow the ring portion 4 to be hooked. Also, the configuration of the belt body 200, the first hook portion 201, and the second hook portion 202 is just one example, and other examples will be described later.

[0025] Next, a method for installing a belt 200 inside a bag-shaped belt insertion section 300 using the insertion tool 100 of Embodiment 1 configured as described above will be explained. First, as the first step, the first hook portion 201 of the belt 200 is hooked onto the second through-hole 41 via the divided portion 42 of the ring portion 4, as shown in Figure 5B. Therefore, at this stage, nothing is hooked onto the second hook portion 202 of the belt 200 (Figure 5C). Next, the ring portion 4 is inserted from the divided portion 42 into the first through-hole 31 of the locking portion 3 of the insertion tool 100, and the second through-hole 41 is locked and attached (Figure 6A).

[0026] In addition, the first step may involve first inserting the ring portion 4 into the first through-hole 31 of the locking portion 3 of the through-tool 100 from the dividing portion 42 and locking the second through-hole 41, and then hooking the ring portion 4 into the second through-hole 41 via the dividing portion 42 of the ring portion 4 on the first hook portion 201 of the belt 200.

[0027] Next, as the second step, as shown in Figure 6B, the tip 1 of the threading tool 100 is inserted into the belt threading section 300 through the opening 301 of the belt threading section 300. Next, as the third step, the threading tool 100 is moved into the belt threading section 300 and pulled out from the opening 301 of the belt threading section 300 until the first hook portion 201 of the belt 200 is exposed.

[0028] Here, the direction of penetration of the first through-hole 31 of the locking portion 3 is the second direction Y. Therefore, the ring portion 4, whose second through-hole 41 is locked to the first through-hole 31 of the locking portion 3, is highly likely to come out of the first through-hole 31 when a force is applied in the second direction Y. However, in the belt installation method described above, the direction of travel of the pass-through tool 100 is the first direction X, and a force in the second direction Y is almost never applied to the ring portion 4. Therefore, in the belt installation method, it is possible to prevent the ring portion 4 from coming out of the locking portion 3.

[0029] Furthermore, since the first hook portion 201 of the strap 200 is hooked into the second through hole 41 of the ring portion 4, the likelihood of the strap 200 coming off the ring portion 4 is greatly reduced. Moreover, the strap 200 moves in the direction of travel of the pass-through tool 100 with its plane parallel to and in the same direction as the plane 20 of the base portion 2 of the pass-through tool 100. This prevents the strap 200 from twisting within the strap pass-through portion 300. As a result, the strap 200 can move easily within the strap pass-through portion 300, and the strap 200 can be easily installed within the strap pass-through portion 300 without twisting.

[0030] Furthermore, when moving the threading tool 100 into the belt threading section 300, the rigidity of the tip 1 is greater than that of the base 2, making it easier to move within the belt threading section 300. Also, since the base 2 has a flat surface 20, it is easier to grasp the threading tool 100 within the belt threading section 300, facilitating the work. In addition, since the base 2 is flexible in the third direction Z, it is easier to move the base 2 of the threading tool 100 within the belt threading section 300 by bending it in the third direction Z.

[0031] Next, in the fourth step, the ring portion 4 is removed from the locking portion 3 of the pass-through tool 100 via the dividing portion 42 through the first through hole 31. Next, in the fifth step, the second hook portion 202 of the belt 200 is inserted through the dividing portion 42 of the ring portion 4 and into the second through hole 41 of the ring portion 4, forming the belt 200 into a ring shape via the ring portion 4. Then, the belt 200, which is formed into a ring shape by connecting the first hook portion 201 and the second hook portion 202 with the ring portion 4, is installed inside the belt pass-through portion 300 (Figures 8 and 9).

[0032] As described above, the ring portion 4 of the pass-through device 100 is eventually detached from the locking portion 3 of the pass-through device 100 and remains inside the belt pass-through portion 300 together with the belt 200. For this reason, the size and material of the ring portion 4 are appropriately selected and formed considering ease of attachment and durability against washing.

[0033] Here, another example of the band 200 will be described. For example, as shown in Figures 10A and 10B, it is possible to form the first hook portion 201 and the second hook portion 202 by pressing (for example, heat pressing) another fabric-like member 230 that is thinner than the band 200 to both ends of the band 200 to form a pressed portion 211 and a loop. In this case, since the first hook portion 201 and the second hook portion 202 are formed from the fabric-like member 230, the thickness of that portion is reduced compared to the case shown in Figure 4 above, and thus the ease of attachment is improved.

[0034] Another example is to tie a portion of each end of the belt 200 together to form a loop, thereby forming the first and second hooks. This is considered particularly effective when the belt 200 is in the shape of a string. Another example is to equip each end of the belt 200 with hooks or the like and fasten them together to form a loop, thereby forming the first and second hooks.

[0035] Another example is a band 200, as shown in Figure 11. This band 200 is stretchable in the longitudinal direction (first direction X), and has an upper pleated portion 221 formed in a continuous pleated shape in the longitudinal direction on the upper side Y1 in the short direction (second direction Y), and a lower pleated portion 222 formed in a continuous pleated shape in the longitudinal direction on the lower side Y2 in the short direction. On one side (back side Z2), the areas where the upper pleated portion 221 and lower pleated portion 222 are not formed are flat, and on the other side (front side Z1), there are multiple rectangular protrusions 223 spaced apart in the longitudinal direction in the areas where the upper pleated portion 221 and lower pleated portion 222 are not formed. Each protrusion 223 is stretchable in the thickness direction (third direction Z).

[0036] As shown in Figure 11, in the case of a belt 200 formed in this manner, for example, if the bag-shaped belt loop 300 is located around a person's waist, when a person wears it, the convex portion 223 is formed on the side that touches the person, thus reducing the tightness caused by the belt 200. Furthermore, the formation of the convex portion 223, the upper pleat portion 221, and the lower pleat portion 222 creates friction between the inside of the belt loop 300 and the convex portion 223, the upper pleat portion 221, and the lower pleat portion 222, preventing the belt 200 from turning inside out or bending inside the belt loop 300. In addition, because of the presence of the convex portion 223, the upper pleat portion 221, and the lower pleat portion 222, there is almost no discomfort caused by the ring portion 4.

[0037] In Figure 11, an example is shown in which the band has a convex portion 223, an upper pleat portion 221, and a lower pleat portion 222. However, it is not limited to this, and other configurations are also possible, such as when only the convex portion 223 is present, when the convex portion 223 and the upper pleat portion 221 are present, or when the convex portion 223 and the lower pleat portion 222 are present. However, especially when the width of the band 200 (second direction Y) is narrow, having all three—the convex portion 223, the upper pleat portion 221, and the lower pleat portion 222—can reliably prevent the band 200 from turning inside out or folding.

[0038] According to the passing device of Embodiment 1 configured as described above, The tip and, A base connected to the aforementioned tip, A pass-through device comprising a locking portion connected to the side of the base opposite to the tip portion, If the longitudinal direction of the aforementioned through-device is designated as the first direction, the direction perpendicular to the first direction as the second direction, and the direction perpendicular to both the first and second directions as the third direction, The base is formed in a plate shape having planes parallel to the first and second directions, and is flexible in the third direction. The locking portion is provided with a first through hole that penetrates in the second direction. Therefore, When the band is inserted into the pouch-shaped band loop, the possibility of it coming off the loop is reduced.

[0039] Furthermore, according to the through-device of Embodiment 1 configured as described above, The locking portion is equipped with a ring portion that can be detachably locked to the locking portion, The ring portion includes a second through-hole that penetrates in a third direction, and a dividing portion that divides the second through-hole. Therefore, When the band is inserted into the pouch-shaped band loop, the possibility of it coming off the loop can be further reduced.

[0040] Furthermore, according to the through-device of Embodiment 1 configured as described above, The rigidity of the tip portion is formed to be higher than that of the base portion. Therefore, The threading tool offers excellent operability.

[0041] Furthermore, according to the through-device of Embodiment 1 configured as described above, The aforementioned tip portion is It is formed by a conical portion having a central axis in the first direction and with its apex on the front side, and a columnar portion connected to the rear side of the conical portion. Therefore, The operability of the threading tool is even better.

[0042] Furthermore, according to the strip installation method of Embodiment 1 configured as described above, In a method for installing a belt in which the belt is installed inside a bag-shaped belt-passing section using the pass-through device described above, The strip has a first hook portion on one end in the first direction and a second hook portion on the other end, The first step involves inserting the ring portion into the first through-hole of the locking portion of the pass-through device from the dividing portion and locking the second through-hole, and attaching the first hook portion of the band to the second through-hole via the dividing portion of the ring portion, A second step involves inserting the tip of the aforementioned pass-through tool into the belt pass-through portion through the opening of the belt pass-through portion, A third step involves moving the pass-through tool into the belt pass-through section and pulling the pass-through tool out from the opening of the belt pass-through section until the first hook portion of the belt is exposed. A fourth step involves removing the ring portion from the first through-hole of the locking portion of the passing device via the dividing portion. The fifth step involves inserting the second hook portion of the strip into the divided portion of the ring portion, inserting it into the second through hole of the ring portion, and forming the strip into an annular shape via the ring portion. The belt can be securely installed using the fastener.
