Description

Technical Field

[0001] This disclosure relates to a zipper tooth belt formed by weaving a spiral member with zipper teeth continuously formed in a monofilament spiral into a zipper belt. Background Technology

[0002] Japanese Patent Publication No. 57-25204 discloses a zipper with a zipper tooth tape having a structure in which spiral members are woven into the zipper tape. As described in that document... Figure 2 As shown, a spiral component (refer to reference numeral 8) is installed on the ground weave of the zipper tape using the up-and-down swinging upper warp yarns (refer to reference numerals 11 and 12). Two core ropes are inserted at intervals within the spiral component. Summary of the Invention

[0003] The problem that the invention aims to solve

[0004] A zipper belt is constructed by weaving in a spiral member, in which zipper teeth are continuously formed within a monofilament spiral. The spiral member is secured by fastening yarns relative to the weave of the zipper belt. Relatedly, to maintain the mechanical shape of the spiral member, a core cord is sometimes introduced into it. However, due to the introduction of the core cord, the space available for the fastening yarns is reduced. Consequently, if the tension applied to each fastening yarn is increased, the weft yarn is lifted upwards between the lower legs of the zipper teeth, potentially exposing the lower legs of the zipper teeth on the lower surface of the zipper belt (the side of the zipper belt opposite to the zipper teeth). As a non-limiting example, when the tension applied to each fastening yarn is increased in accordance with the introduction of a thicker core cord, the lower legs of the zipper teeth may be exposed, as described above.

[0005] As can be seen from the above non-limiting illustrative description, it is desirable to develop a new weaving method for a spiral member that can easily ensure the desired number of yarns even when a core cord is introduced.

[0006] [Methods used to solve problems]

[0007] A zipper belt according to the present disclosure includes: a spiral member, which is formed by continuously forming a plurality of zipper teeth in a monofilament spiral, each zipper tooth including an upper leg, a lower leg, an engaging head, and a reversing portion; at least two core cords passing through the spiral member; and a zipper belt having a ground weave composed of a plurality of ground warp yarns and at least one ground weft yarn. The zipper belt includes a belt body and a first side edge portion in which the spiral member is woven. The first side edge portion includes a plurality of ground warp yarns for supporting the lower legs of the plurality of zipper teeth and a plurality of fastening yarns for fastening the spiral member relative to the ground weave. The spiral member has a transverse width defined by a first imaginary line on the same side as the engaging heads of the plurality of zipper teeth and a second imaginary line on the same side as the reversing portions of the plurality of zipper teeth. The at least two core cords are arranged adjacent to each other within the transverse width of the spiral member, near the second imaginary line. The multiple fastening yarns include: M (M represents a natural number greater than 1) first fastening yarns, which are arranged within the transverse width of the helical member at a position closer to the first imaginary line than at least 2 core ropes; and N (N represents a natural number greater than 1) second fastening yarns, which are arranged between adjacent core ropes in at least 2 core ropes, where M is greater than N.

[0008] In several implementations, M is a natural number greater than 3, and N is a natural number less than 2.

[0009] It can be that M is any natural number among 3, 4, and 5, and N is 1.

[0010] In several embodiments, the multiple ground warp yarns include (i) three or more ground warp yarns disposed within the transverse width of the helical member at a position closer to the first imaginary line than the M first fastening yarns. Alternatively, the multiple ground warp yarns include (ii) two or fewer ground warp yarns disposed between adjacent first fastening yarns in the M first fastening yarns. Alternatively, the multiple ground warp yarns include (iii) two or fewer ground warp yarns disposed between the M first fastening yarns and the N second fastening yarns.

[0011] In several embodiments, the zipper chain strap also has a pressing mechanism that presses against the spiral member relative to the ground structure at the first side edge. The pressing mechanism may include at least one first core yarn and at least one additional weft yarn. At least one first core yarn may pass through the spiral member and be positioned closer to the first imaginary yarn than M first fastening yarns within the lateral width of the spiral member. At least one additional weft yarn may be supplied in a manner that interweaves with the at least one core yarn within the lateral width of the spiral member and crosses the upper leg on the upper side.

[0012] In several embodiments, at least one additional weft yarn forms a ground structure in the main body of the belt.

[0013] In several embodiments, the pressing structure further includes at least one second core yarn that extends through the helical member and is positioned closer to the first imaginary yarn than the M first fastening yarns within the transverse width of the helical member. It is possible that at least one ground weft yarn is interwoven with at least one second core yarn to abut against the upper surface of the lower leg.

[0024] Hereinafter, non-limiting embodiments and features of the present invention will be described with reference to the accompanying drawings. Repeated descriptions between embodiments are generally omitted. The description is primarily for the purpose of illustrating the invention, and simplifications are made for ease of drawing.

[0025] Reference Figure 1 and Figure 2The zipper tooth strip 1 includes a zipper strip 4, a spiral member 2 woven into the zipper strip 4, and two core cords C1 and C2 passing through the spiral member 2. In zippers not shown, the zipper tooth strips 1 are used in pairs and can be opened and closed by a zipper pull (not shown). The zipper tooth strip 1 extends in a long strip with a specified width in a specified direction (specifically, the warp direction). The zipper tooth strip 1 is flexible in both the width and length directions, that is, even when the spiral member 2 is woven into the zipper strip 4, a certain degree of flexibility of the zipper tooth strip 1 can be ensured.

[0026] The following description introduces a new weaving method for the spiral member 2, which ensures a desired number of fastening yarns even when the core cord is introduced. As an optional effect, it allows for an increase in the number of fastening yarns and reduces the tension applied to each fastening yarn. This prevents or inhibits the spiral member 2 from interfering with the lower surface of the zipper tooth tape 1 (and...). Figure 1 The opposite side of the upper surface shown is partially exposed (specifically, the lower leg 52 of the zipper tooth 5 described later is exposed).

[0027] The following is a more detailed explanation. The zipper tape 4 has many warp yarns 3 m and at least one ground weft yarn 6 m The zipper tape 4 is woven with a ground weave. Furthermore, the zipper tape 4 includes a first side edge portion 41 and a tape body portion 45; in other words, it is divided into a first side edge portion 41 and a tape body portion 45 in the weft direction. The tape body portion 45 contains ground warp yarns 3. m Hedi weft yarn 6 m The woven ground fabric typically consists of only a ground fabric, but is not limited to this. There are no restrictions on the type (plain weave, twill weave, etc.) and combination of weave structures in the main body 45. Furthermore, the main body 45 is typically wider than the first side edge 41.

[0028] The first side edge 41 includes multiple ground warp yarns 31-35 for each lower leg 52 of the multiple zipper teeth 5 to be placed, and multiple fastening yarns T1, T2, T3, T4 for fastening the spiral member 2 relative to the ground weave. The ground weft yarn 6... m The ground weave consists of multiple ground warp yarns 31-35 forming the first side edge portion 41. The spiral member 2 is fastened relative to the ground weave by fastening yarns T1, T2, T3, and T4. Furthermore, the zipper tape 4 can include a second side edge portion (not shown) on the side opposite to the first side edge portion 41 in the weft direction.

[0029] The spiral member 2 is a member in which a plurality of zipper teeth 5 are continuously formed in a helix of a monofilament, having a certain lateral width W2 and extending elongated in the warp direction. The plurality of zipper teeth 5 are arranged continuously in the warp direction. Each zipper tooth 5 includes an upper leg 51, a lower leg 52, an engaging head 53, and a reversing part 54. The lateral width W2 of the spiral member 2 is defined by a first imaginary line L1, for example tangent to each engaging head 53 on the same side as each engaging head 53 of the plurality of zipper teeth 5, and a second imaginary line L2, for example tangent to each reversing part 54 on the same side as each reversing part 54 of the plurality of zipper teeth 5. Typically, the spiral member 2 is woven into the first side edge 41 by feeding a monofilament with engaging heads 53 formed at predetermined intervals into a needle loom, but this method is not limited to this.

[0030] In each zipper tooth 5, the upper leg 51 and the lower leg 52 extend in the weft direction. The upper leg 51 and the lower leg 52 do not need to be parallel. The engaging head 53 extends vertically along the outer edge of the zipper tape 4 to connect the outer end of the upper leg 51 to the outer end of the lower leg 52. The reversing portion 54 extends curved vertically along the zipper tape 4 to connect the inner end of the upper leg 51 and the inner end of the lower leg 52 of adjacent zipper teeth 5. The engaging head 53 has a portion that is wider radially than other parts of the monofilament (e.g., the upper leg 51 and the lower leg 52), thereby enabling the engagement and disengagement of the spiral members serving as an engaging pair. Furthermore, the aforementioned outer and inner ends are defined relative to the in-plane direction of the zipper tape 4.

[0031] Two core cords C1 and C2 pass through the spiral member 2 (specifically, between the upper leg 51 and lower leg 52 of each zipper tooth 5 in a warp-up continuous manner) and extend in a long strip (e.g., straight) in the warp direction. The core cords C1 and C2 are soft threads with elasticity and / or bulkiness corresponding to the shape-restoring force of their constituent lines, inserted and held between the upper leg 51 and lower leg 52. The core cords C1 and C2 can be, for example, braided rope units, structures formed by sealing braided ropes inside a bag, but other structures are also possible. With the vertical spacing between the upper leg 51 and lower leg 52 narrowed using fastening yarns T1, T2, T3, and T4, the core cords C1 and C2 can be clamped and compressed between the upper leg 51 and lower leg 52, but are not necessarily limited to this.

[0032] In this embodiment, the two core cords C1 and C2 are arranged adjacently within the lateral width W2 of the spiral member 2, close to the second imaginary line L2. Furthermore, the first fastening yarns T1, T2, and T3 are arranged within the lateral width W2 of the spiral member 2 at positions closer to the first imaginary line L1 than the two core cords C1 and C2, and the second fastening yarn T4 is arranged between adjacent core cords C1 and C2. When the number of the first fastening yarns is set to M (M represents a natural number greater than or equal to 1) and the number of the second fastening yarns is set to N (N represents a natural number greater than or equal to 1), M is greater than N (i.e., M>N). Thus, a new weaving method can be provided for the spiral member where the desired number of fastening yarns can be easily ensured even when core cords are introduced. Specifically, instead of introducing a single, thicker core cord, multiple core cords (e.g., two) are introduced into the spiral member, and a relatively small number of fastening yarns are arranged between adjacent core cords. Although multiple core cords can be considered as a single, thicker core cord, the number of tightening yarns (e.g., +1, +2, etc.) can be increased by placing tightening yarns between the core cords. Increasing the number of tightening yarns helps reduce the tension applied to each tightening yarn, thus suppressing or preventing the lower leg 52 of the zipper tooth 5 from being exposed on the lower surface of the zipper tooth belt 1 (due to the tightening yarn pulling upwards against the ground weft yarn). Furthermore, the second tightening yarn T4 is arranged separately from the first tightening yarns T1, T2, and T3, promoting a sparser distribution of the tightening yarns. This sparse distribution of the tightening yarns helps reduce the degree to which the lower leg is exposed due to the tightening yarn pulling upwards against the ground weft yarn.

[0033] Although M and N are not limited to specific values, since the width of the first side edge 41 is limited and the line itself has an inherent width, it is preferable that M is a natural number of 3 or more and N is a natural number of 2 or less. More preferably, M is any natural number among 3, 4, and 5 and N is 1.

[0034] The floating and sinking cycles of the first fastening yarns T1, T2, and T3 are preferably complementary to those of the adjacent first fastening yarns. That is, fastening yarns T1 and T3 float and sink synchronously (although their weft interlacing positions are different, they are at the same warp position with the common ground weft yarn 6). m Interlacing. The weft yarn 6, which is not interlaced with the weft yarn 6 at the same warp position, floats and sinks in a complementary manner to the floating and sinking cycles of the fastening yarns T1 and T3. m Intertwined.

[0035] The floating and sinking period of the second fastening yarn T4 is the same as that of the fastening yarns T1 and T3, or the same as that of the fastening yarn T2. ​​Considering the first fastening yarns T1, T2, T3, and the second fastening yarn T4 as a group of fastening yarns, it can be said that the core cord C1 is positioned near the second imaginary line L2 between the fastening yarns T3 and T4 (ignoring the ground warp 35). Here, instead of one core cord, two core cords are used; therefore, the thickness and width of the core cord C1 are relatively smaller, and the second fastening yarn T4 is positioned closer to the first fastening yarns T1, T2, and T3. Therefore, it is more preferable that the floating and sinking period of the second fastening yarn T4 is the same as that of the fastening yarn T2.

[0036] In this embodiment, features that can be independently extracted from or synergistically combined with the aforementioned features include three or more fastening yarns, such as the first fastening yarns T1, T2, T3, and the second fastening yarn T4. Therefore, even with reduced tension applied to each fastening yarn, the spiral member 2 can be stably fixed relative to the ground weft of the zipper tape 4, promoting more stable fastening. Preferably, the ground weft yarn 6 is not loosened. m The first fastening yarns T1, T2, T3 and the second fastening yarn T4 are supplied by a relatively large upward lifting motion (see reference). Figure 2 For example, the ground weft yarn 6 m 6 weft yarns m The interlacing point with the fastening yarn T1 is also located near the lower surface of the lower leg 52. The same applies to the interlacing points with other fastening yarns. More simply, the ground weft yarn 6... m It will not be pulled up by the fastening yarn to a position above the plane PL51, which is located at the center of the upper and lower thicknesses of the lower leg 52. Therefore, it is possible to avoid or suppress the lower leg 52 from being pulled up on the lower surface 4z of the zipper tape 4 (see reference). Figure 2 Exposure. In addition, reducing the tension applied to each fastening yarn can also improve the softness of the first side edge 41.

[0037] As described above, the first side edge portion 41 includes multiple ground warp yarns 31-35. The multiple ground warp yarns 31-35 may include (i) three or more ground warp yarns 31-33 disposed within the transverse width W2 of the spiral member 2 at a position closer to the first imaginary line L1 than the M first fastening yarns T1, T2, T3; (ii) two or fewer ground warp yarns 34 disposed between adjacent first fastening yarns among the M first fastening yarns T1, T2, T3; and (iii) two or fewer ground warp yarns 35 disposed between the M first fastening yarns T1, T2, T3 and the N second fastening yarns T4, or any two or all of these.

[0038] In the case of three or more ground warp yarns 31 to 33 including (i), the M first fastening yarns T1, T2, and T3 are positioned further away from the first imaginary line L1, which can prevent accidental contact between the spiral member and the engaging object of the spiral member 2.

[0039] In the case of two or fewer ground warp yarns 34 including (ii), the upward lifting effect of the fastening yarn on the ground weft yarn can be mitigated. For example, fastening yarns T1 and T3 float synchronously (although they are different in the weft direction, but) at the same warp position with the common ground weft yarn 6. m The interlacing works by lifting it upwards. Between the fastening yarns T1 and T3, there is a fastening yarn T2 with a floating pattern that complements them, but the presence of the ground warp 34 further mitigates the effect of the upward lift.

[0040] In the case of two or fewer ground warp yarns 35 including (iii), the ground weft yarn 6 m The position between the M first fastening yarns T1, T2, T3 and the N second fastening yarns T4 is supported by the ground warp yarn 35 and can resist the upward pull caused by the fastening yarns.

[0041] It is not necessary to include all the ground warp yarns listed in (i) to (iii) above, but it may include any one or two of them.

[0042] Finally, the optional structure of the zipper tape 4 will be described. The zipper tape 4 can also have a pressing structure in which the spiral member 2 is pressed against the ground fabric at the first side edge 41. This pressing structure includes at least one first core yarn CY1 and at least one additional weft yarn 6. n The first core yarn CY1 passes through the spiral member 2 and is positioned within the transverse width W2 of the spiral member 2, closer to the first imaginary yarn L1 than the M first fastening yarns T1, T2, and T3. Additional weft yarns 6 are supplied in such a manner that they interweave with at least one core yarn CY1 within the transverse width W2 of the spiral member 2 and cross the upper leg 51 on the upper side. n Using the additional weft yarn 6 n Press the upper leg 51 of the spiral member 2 toward the ground tissue side, thereby promoting a more stable fixation of the spiral member 2.

[0043] In the example diagram, the additional weft yarn 6 n The weave is formed in the main body 45, but is not limited to this. Additional weft yarns 6 n The first side edge 41 can also be selectively introduced at a location or selectively at a region. For example... Figure 2 As shown, 6 additional weft yarns n In order to relative to the adjacent warp yarn in the latitudinal direction 3 m (For example, Figure 2 The 3 in the middle diagramm1 ~3 m8 The yarn floats and extends in the main body 45 while swinging in the weft direction, and extends upward in the first side edge 41, crossing the core ropes C1 and C2, intertwining with the first core yarn CY1 and changing direction (moving in the opposite direction in the weft direction), crossing the upper leg 51. Although not shown, the additional weft yarn 6 n Then, cross over the core ropes C1 and C2 and return to the formation process of the ground structure of the zipper belt 4.

[0044] The pressing structure may also include at least one second core yarn CY2, which extends through the helical member 2 and is positioned within the transverse width W2 of the helical member 2 closer to the first imaginary line L1 than the M first fastening yarns T1, T2, T3. Ground weft yarn 6 m In order for the second core wire CY2 to abut against the upper surface of the lower leg 52 and intertwine with at least one second core wire CY2 (see reference). Figure 2 By pressing the lower leg 52 of the spiral member 2 towards the ground weave side using the second core yarn CY2, a more stable fixation of the spiral member 2 can be achieved. Of course, the second core yarn CY2 and its corresponding ground weft yarn 6 can be omitted. m The intertwining of.

[0045] Reference Figures 3 to 6 The variations are explained. For example... Figure 3 As shown, three core ropes C1 to C3 can also be inserted into the spiral member 2, achieving the same effect as described above. It should be noted that as the thickness (or width) of each core rope decreases, the interval between the first fastening yarns T1 to T3 and the second fastening yarn T4 may also decrease. For example... Figure 4 As shown, a second fastening yarn T4 can also be introduced between adjacent core ropes C2 and C3, located further away from the first fastening yarns T1 to T3 among the three core ropes C1 to C3. For example... Figure 5 As shown, alternatively, a second fastening yarn T can be inserted between adjacent core ropes C1 and C2 among the three core ropes C1~C3. 41 And another second fastening yarn T is inserted between adjacent core ropes C2 and C3. 42 It should be noted that although the number of fastening yarns can be increased, the space available for the ground warp yarns in the first side edge 41 is reduced. For example... Figure 6 As shown, multiple second fastening yarns T can also be inserted between adjacent core ropes C1 and C2. 41 T 42 Second fastening yarn T 41 T 42 It should have a relative ground weft yarn of 6 m Complementary floating and sinking cycles. Given the second fastening yarn T 41 T 42Increasing the number of yarns (from 1 to 2) can also reduce the number of yarns in the first fastening yarn.

[0046] Figure 7 It is paired including based on Figure 1 and Figure 2 The image is a photograph taken of the central portion of the lower surface of the zipper chain in the closed state of the zipper teeth of the embodiment shown. Figure 8 This image is a photograph taken of the central portion of the lower surface of a zipper chain in its closed state, containing pairs of zipper teeth as in the comparative example. In the embodiment, two core cords are used, but in the comparative example, only one core cord is used. In the comparative example, there is one less fastening yarn, resulting in greater tension applied to each fastening yarn. As a result, as... Figure 8 As shown, on the lower surface of the zipper tooth belt 1, the lower legs 52 of each zipper tooth 5 of the spiral member 2 are exposed near the reversing portion 54. This is the ground weft yarn 6. m The result is that the fastening yarn is pulled upwards. In this embodiment, compared to the comparative example, a greater number of fastening yarns can be secured, bringing the opposing ends (sides) of the first side edge 41 closer together in a pair of zipper straps 4, thereby limiting the exposure of the lower leg 52 to the engaging head or its vicinity. In other comparative examples, which differ from the comparative example without increasing the tension of the individual fastening yarns, it is foreseeable that the fixation of the spiral member will be weaker.
