Description

[Technical Field]

[0001] The present invention relates to a fastening device, primarily for attaching tags indicating price, quality, etc. to products such as clothing, fabrics, and textiles, or for holding a pair of products such as socks or gloves by sandwiching them between a backing and penetrating the backing and the product. [Background technology]

[0002] Several types of fastening members have been known in the past, including a pin-type fastening member that has a horizontal bar integrally attached to one end of the drawn fiber portion to prevent it from coming loose, and a paddle integrally attached to the other end to prevent it from coming loose, and a fastening member that has an insertion portion at one end of the fiber portion and a receiving portion at the other end into which the insertion portion is inserted and locked, forming a loop with the fiber portion.

[0003] Conventional fastening members are cut with scissors or a cutter and pulled out of the product to remove the tag from the product after purchase. This requires the tedious process of cutting the fastening member with scissors or a cutter. For fastening members that form a loop, structures have been developed that allow the locking portion of the loop to be freely locked and unlocked. However, unlocking the lock requires tedious work.

[0004] Therefore, in order to eliminate the above-mentioned troublesome work, the inventors of the present application have proposed a fastening member in which a breaking portion is formed between the fiber portion and the slip-out prevention component (see Patent Document 1). With this fastening member, the fiber portion separated from the slip-out prevention component by breaking the breaking portion can be shaped so that there are no parts that will obstruct the removal of the fastening member from the product. Therefore, the fastening member can be removed from the product without any troublesome work. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2023-91278 Summary of the Invention [Problem to be solved by the invention]

[0006] In the fastening member proposed in Patent Document 1, the tab used to break the breaking part protrudes from the end of the anti-slip component, which means that fibers that make up the product may get caught on the tab or get caught in the gap formed in the anti-slip component, which may result in damage to the product. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the fastening member of the present invention has a fiber portion that penetrates an object, a horizontal bar portion for preventing the fiber portion from coming off that is connected to one end of the fiber portion, and a pull-out prevention component that is arranged on the other end side of the fiber portion, and the other end side of the fiber portion has a bent portion that is bent at a predetermined angle with respect to the extension direction of the one end side and extends in the bent direction, and the pull-out prevention component is formed in a U-shape by connecting two portions that extend parallel to the extension direction of the bent portion, and one of the two portions is connected to the bent portion via a break portion, and The position of the tip of one of the two parts is set near the position of the tip of the bent part, and the other of the two parts has a gripping part, and by gripping the gripping part and pulling it in the extension direction of one end of the fiber part away from the horizontal bar part, the breaking part breaks and the fiber part and the anti-pullout component part separate, and the separated fiber part takes a shape that can be pulled out from the object through which it is passing.In this fastening member, the position of the tip of the other part is set at the same position as or set back from the position of the tip of the one part. [Effects of the Invention]

[0008] According to the present invention, the tip of the other of the two parts extending parallel to the extension direction of the bent part is set at the same position as or set back from the tip of the one of the parts. That is, the other part having the gripping part does not protrude forward relative to the tip of the one of the parts. This is advantageous in avoiding problems such as fibers or the like constituting the object getting caught in the gripping part or getting caught in the gap between the one of the parts.

[0010] Hereinafter, a fastening member of the present invention will be described based on an embodiment shown in the drawings.

[0011] 1 to 3 includes a fiber portion 2, a horizontal bar portion 5 connected to one end of the fiber portion 2 for preventing it from coming off, and a fall-off prevention component 8 arranged on the other end side of the fiber portion 2. The X arrow, Y arrow, and Z arrow in the figures indicate the length direction, width direction, and thickness direction of the fastening member 1, respectively, which are perpendicular to each other.

[0012] 1 to 3 show an assembly in which a number of fastening members 1 are connected to one runner bar 3. More specifically, the cross bar portion 5 of each fastening member 1 is connected to the runner bar 3 via a narrowed connecting portion 4. The runner bar 3 extends in the Z direction, and each fastening member 3 is arranged side by side at intervals in the Z direction. Each fastening member 1 and connecting portion 4 are integrally molded with the runner bar 3.

[0013] The fastening member 1 of this embodiment is made of nylon that has been stretched and toughened. The material from which the fastening member 1 is made is not limited to various resins that have been conventionally used, but may also be recycled resin (such as recycled polypropylene), biomass material, biodegradable material, etc.

[0014] When using the fastening member 1, the runner bar 3 is loaded into a known attachment tool, and the connecting portion 4 is cut with a cutter on the attachment tool. As a result, each fastening member 1 is used as a single unit separated from the runner bar 3. When the fastening member 1 is in use, the fiber portion 2 penetrates the target object, such as a tag T or a product (clothing, fabric, textile material, etc.). The target object through which the fiber portion 2 has penetrated is positioned between the horizontal bar portion 5 and the bending portion 6. As a result, the horizontal bar portion 5 and the anti-slip structural portion 8 prevent the fastening member 1 from coming off the target object.

[0015] The fiber portion 2 is rod-shaped, and one end thereof extends perpendicular to the cylindrical horizontal bar portion 5. In this embodiment, the fiber portion 2 is cylindrical. The length L1 of the horizontal bar portion 5 is, for example, 5 mm to 10 mm, and the outer diameter of the horizontal bar portion 5 is, for example, 0.6 mm to 1.0 mm.

[0016] The other end of the fiber portion 2 has a bent portion 6 that is bent at a predetermined angle a with respect to the extension direction (X direction) of the one end and extends in the bent direction. That is, the fiber portion 2 is bent at the predetermined angle a at a position midway in the longitudinal direction. In this embodiment, the predetermined angle a is set to 90°, and the fiber portion 2 is formed in an L shape. The predetermined angle a is set to a desired angle within the range of 90°±15°, for example. The dashed-dotted line extending in the X direction in the figure indicates the axis of one end of the fiber portion 2, and the dashed-dotted line extending in the Y direction in FIG. 1 indicates the axis of the bent portion 6.

[0017] In this embodiment, one end side of the fiber portion 2 extending in the X direction has a tapered portion 2b that gradually reduces in diameter toward the connecting base end 2a, and the connecting base end 2a, which is one end of the fiber portion 2, has the portion with the smallest diameter in the fiber portion 2. The connection portion between the connecting base end 2a and the horizontal bar portion 5 is formed in an arc shape (rounded), and the fiber portion 2 is connected to the horizontal bar portion 5 via the connecting base end 2a. The one end side of the fiber portion 2 extending in the X direction can also be a cylinder with a constant outer diameter.

[0018] The bent portion 6 is a rod-like body bent in an arc shape at a predetermined angle a. In this embodiment, the bent portion 6 is cylindrical with a constant outer diameter over its entire length in the longitudinal direction. The outer diameter of the bent portion 6 is, for example, 0.8 mm to 1.2 mm, which is larger than that of the horizontal bar portion 5.

[0019] The slip-out prevention component 8 is a U-shaped plate-like body formed by connecting two portions 8a and 8b (one portion 8a and the other portion 8b) that extend parallel to the extension direction (Y direction) of the bending portion 6. The length L2 of the slip-out prevention component 8 is, for example, 8 mm to 12 mm, and is longer than the length L1 of the horizontal bar portion 5 (length L2 > length L1). The widths W1 and W2 of the two portions 8a and 8b are, for example, 1 mm to 1.4 mm. In this embodiment, the widths W1 and W2 are the same. The width W1 may be smaller than the width W2, or the width W1 may be larger than the width W2.

[0020] A gap 9 with an open tip side is formed between one portion 8a and the other portion 8b. The size of this gap 9 (the distance in the X direction) is, for example, 0.2 mm to 0.8 mm.

[0021] One portion 8a is connected to the bent portion 6 via the breaking portion 7, and the position of the tip of the one portion 8a is set near the position of the tip of the bent portion 6 (substantially the same position with a difference of about ±0.1 mm). In this embodiment, the position of the tip of the other portion 8b is set at a position set back from the position of the tip of the one portion 8a, and is located approximately in the center of the one portion 8a in the longitudinal direction (Y direction).

[0022] The position of the tip of the other part 8b may be set at the same position as or set back from the position of the tip of the one part 8a. In other words, the tip of the other part 8b may not protrude forward from the tip of the one part 8a. The setback amount R of the tip of the other part 8b from the tip of the one part 8a is set to a desired value in the range of 0 mm to 6 mm.

[0023] The other part 8b has a gripping portion 10 that is flatter than its width W, and the gripping portion 10 is located at the tip of the other part 8b. The gripping portion 10 is large enough to be held securely between the thumb and index finger, and in this embodiment, as shown in FIG. 1, has a shape similar to a circle in plan view. There are no particular restrictions on the shape of the gripping portion 10 as long as it can be held with the fingers, but a shape without corners is preferable. Furthermore, as shown in FIGS. 2 and 3, both surfaces of the gripping portion 10 bulge out in a dome shape. The thickness t of the gripping portion 10 is large enough to be compact yet large enough to be held with the fingers. To make it easier to hold with your fingers, the thickness is set to, for example, 0.6 mm to 1.2 mm.

[0024] The breaking portion 7 extends continuously from the tip to the rear end of the bent portion 6. The breaking portion 7 is a film thinner than the bent portion 6 and the slip-out prevention structure 8, and its thickness is, for example, 0.1 mm to 3.0 mm, with approximately 0.15 mm being particularly preferable. The width G of the breaking portion 7, i.e., the distance G between the bent portion 6 and one portion 8a, is, for example, 0.2 mm to 0.6 mm. The length L3 of the breaking portion 7 is, for example, 3 mm to 6 mm.

[0025] The rear end of the breaking portion 7 is inclined backward (toward the X direction) from the bent portion 6 toward the slip-out prevention component 8, and the acute angle b formed by the extending direction of the bent portion 6 and the inclination of the rear end of the breaking portion 7 is 45° or less. This acute angle b is set to a desired value, for example, in the range of 30° to 45°.

[0026] A method for using the fastening member 1 will now be described.

[0027] As shown in Fig. 4, a tag T is attached to a product (such as clothing, fabric, or woven material) using a fastening member 1. The fiber portion 2 passes through an insertion hole Th of the tag T. The product is disposed between the horizontal bar portion 5 and the bent portion 6 together with the tag T, but is not shown in the figure. The product is also not shown in Figs. 5 and 6, which will be described later.

[0028] When attaching the tag T to a product using the fastening member 1, a known attachment tool is used. The trigger of the attachment tool is operated to insert a hollow needle, which has a slit formed in the axial direction through which the fiber portion 2 passes, into the object (product and tag T). Then, the connecting portion 4 is cut using a cutter provided in the attachment tool to separate the fastening member 1 into a single unit. Then, the horizontal bar portion 5 is pushed through the hollow needle and toward the opposite side using a piston provided in the attachment tool. This causes the fiber portion 2 to penetrate the object, resulting in the state illustrated in Figure 4.

[0029] The fastening member 1 is not limited to being used by attaching a tag T to a product. For example, in the case of a pair of products such as socks and gloves, the products are stacked and held in place by a backing paper bent into a U-shape. The backing paper displays the product's price and quality. The fiber portion 2 can then be passed through the product and backing paper to hold the product in place with the fastening member 1.

[0030] Next, a procedure for pulling out the fastening member 1 illustrated in FIG. 4 from the object will be described.

[0031] First, gripping portion 10 is pinched with fingers. Next, as illustrated in Figure 5, gripping portion 10 is pulled in the extension direction of one end of fiber portion 2, away from horizontal bar portion 5, thereby breaking breaking portion 7. Because there is a gap 9 between one portion 8a and the other portion 8b, the tensile force pulling gripping portion 10 is effectively transmitted to one portion 8a by the principle of leverage, effectively acting to pull one portion 8a away from bent portion 6. As a result, gap 9 in Figure 5 becomes larger as indicated by the arrow, and the distance between one portion 8a and bent portion 6 widens as indicated by the arrow, causing breaking portion 7 to break.

[0032] As shown in Figure 6, the breaking of the breaking portion 7 separates the fiber portion 2 (bending portion 6) and the pull-out prevention component 8. With the original shape of the fastening member 1, even if an attempt was made to pull out the fiber portion 2 from the object (goods) through which it had penetrated, the pull-out prevention component 8 would be an obstacle and prevent the fiber portion 2 from being pulled out. However, once the pull-out prevention component 8 has been separated, the fiber portion 2 becomes rod-shaped (L-shaped), and so it takes on a shape that allows it to be pulled out from the good through which it has penetrated.

[0033] That is, when the fiber portion 2 (bending portion 6) and the slip-out prevention component 8 are separated, the fiber portion 2 can be easily pulled out from the product and tag T through which it has penetrated. As illustrated in FIG. 7, the fiber portion 2 is pulled out from the insertion hole Th of the tag T.

[0034] With this fastening member 1, the breaking portion 7 can be easily broken by simply manually pulling the tab 10, without using a cutting tool such as scissors. As a result, the fiber portion 2 and the pull-out prevention component 8 are separated, allowing the fiber portion 2 to be smoothly pulled out from the object through which it has passed. As in this embodiment, by forming one end of the fiber portion 2 into a cylindrical tapered portion 2b that narrows in diameter toward the horizontal bar portion 5, it is advantageous for more smoothly pulling the fiber portion 2 out of the object, i.e., a commodity (such as clothing, fabric, or woven material).

[0035] The tip of the other portion 8b is set at the same position as or set back from the tip of the one portion 8a (the setback amount R is 0 mm or more). In other words, the other portion 8b having the tab 10 does not protrude forward from the tip of the one portion 8a. Therefore, compared to a specification in which the tab 10 protrudes forward from the tip of the one portion 8a, this is advantageous in avoiding problems such as fibers constituting the product getting caught on the tab 10 or getting caught in the gap 9 between the one portion 8a and the other portion 8b. Therefore, this is advantageous in avoiding damage to the product caused by the fastening member 1. In particular, this fastening member 1 is particularly useful because wool and other materials constituting the product are prone to getting caught on the tab 10 or getting caught in the gap 9.

[0036] In this embodiment, the angle b formed by the inclination of the rear end of breaking portion 7, which extends continuously from the front end to the rear end of bending portion 6, with the direction of extension of bending portion 6 is between 30° and 45°, which makes it easier to break breaking portion 7 smoothly. Furthermore, by positioning the starting point of the rear end of breaking portion 7 near the boundary between the bent portion and the straight portion of bending portion 6 (within a range of about ±0.1 mm from this boundary) as shown in FIG. 1, breaking portion 7 can be more reliably broken from this starting point when gripping portion 10 is pulled.

[0037] When both surfaces of the grip portion 10 are dome-shaped as in this embodiment, the grip portion 10 fits snugly with the fingers, making it easier to grip tightly. This is also advantageous in preventing the fingers from slipping when pulling the grip portion 10.

[0038] In the embodiment illustrated in Fig. 8, the breakable portions 7 are intermittently scattered from the tip to the rear end of the bent portion 6, and are thinner than the bent portion 6 and the slip-out prevention portion 8. By designing the fastening member 1 in this way, it becomes easier to separate the bent portion 6 and the slip-out prevention portion 8. Furthermore, simply by increasing or decreasing the number of scattered breakable portions 7, it becomes easier to adjust the tensile force required to separate the bent portion 6 and the slip-out prevention portion 8 to the desired magnitude.

[0039] 9, the position of the tip of the other part 8b is set to the same position as the position of the tip of the one part 8a (the setback amount R is 0 mm), and the gripping part 10 is positioned midway in the extension direction of the other part 8b. By configuring the fastening member 1 in this way, it is even more advantageous to avoid the problem of fibers and the like that make up the product getting caught in the gap 9 between the one part 8a and the other part 8b.

[0040] In the embodiment illustrated in FIG. 10, the fastening member 1 is designed to have a closing portion 9a that closes the openings at the tips of the two portions 8a and 8b. By designing the fastening member 1 in this manner, it is possible to substantially eliminate the problem of fibers and the like that constitute the product getting caught in the gap 9. The closing portion 9a is not limited to a structure in which it is connected to one portion 8a and the other portion 8b, but can also be a structure in which it is connected to either one of the portions 8a and the other portion 8b and abuts the other in an unconnected state. In the case where the closing portion 9a is a structure in which it is connected to one portion 8a and the other portion 8b, the connecting portion 9a connects the one portion 8a and the other portion 8b with a weak strength that breaks before the breaking portion 7 when the grip portion 10 is pulled.

[0041] The specifications described in each embodiment can be applied to each of the other embodiments. Therefore, for example, the fastening member 1 illustrated in Figures 1, 8, and 9 may be provided with a closing portion 9a. [Explanation of symbols]
