In addition, a kind of no zipper strip zipper is provided according to the present invention, and it is most important to be characterized in that, it is with above-mentioned construction No zipper strip tooth chain band is accommodated in the state in the storage space portion with the tooth chain of the zipper installation component with mounting portion It is installed on tooth chain band mounting portion, and pull head is installed on by the chain denture of the chain dentification in a manner of it can slide.

Moreover, providing a kind of band zipper article according to the present invention, the band zipper article is with no zipper strip zipper, this is without drawing Chain belt zipper has above-mentioned construction.

The effect of invention

No zipper strip tooth chain band (hereinafter, being also abbreviated as " tooth chain band " sometimes) provided by the invention has to be shaped by monofilament In the shape of a spiral or jagged continuous chain tooth and narrow chain tooth fixing component.Also, narrow chain tooth fixing component edge Zipper length direction be applied between the leg up and down of chain tooth, the chain tooth of sequential like is sewed in a series using sewing line and is being matched It sets in the narrow chain tooth fixing component between upper and lower leg.

Herein, zipper strip be in the outer surface of the upper leg of chain tooth or the outer surface of lower leg (with upper and lower leg The opposite face in face relative to each other) with the band structure of the fixed upper leg of state and lower leg that are contacted with upper leg or lower leg Part is the component different from the chain tooth fixing component being applied between upper and lower leg of the invention.That is, tooth chain band of the invention is upper The outside of leg or lower leg is not configured to the so-called zipper strip of fixed upper leg and lower leg, but be configured to with Past common tooth chain band it is different with neotectonics without zipper strip tooth chain band.

In addition, in the present invention, sewing line with the upper leg of each chain tooth and lower leg in a manner of contacting across each chain tooth Upper leg and lower leg, and between adjacent chain tooth on zipper length direction pierce through chain tooth fixing component, thus by continuous Chain tooth sewing be fixed on chain tooth fixing component.In which case it is preferable that chain tooth fixing component is not as previous core wire It is easy flexible component like that on zipper length direction, but has and is difficult to flexible difficult retractility on zipper length direction Construction.

Present invention as described above in do not use zipper strip tooth chain band in the case where, chain tooth sewing on being applied in In chain tooth fixing component (in particular, chain tooth fixing component of difficult retractility) between lower leg.Therefore, the composition as tooth chain band Component, even if can also stably keep the clipping room of chain tooth using chain tooth fixing component without using previous such zipper strip Away from.

Thus, zipper is constituted by the way that tooth chain band of the invention is installed on zipper installation component or with zipper article, It can be realized the lightweight of zipper, the reduction of cost, alternatively, zipper strip can also be used for the purpose different from previous effect (for example, decorative purpose etc.).

In addition, tooth chain band or zipper can be constituted without using zipper strip using the present invention, therefore for example can be by this The tooth chain band of invention is installed on zipper installation component be bent into bending etc. in stable conditionly.Also, in this case, no Can occur zipper strip present in previous zipper heave, be recessed or ripple shape pleat the problems such as, therefore can be improved band The aesthetics (exterior quality) of zipper article.

In addition, in the present invention, the lower leg of each chain tooth have and engageable head continuously along zipper width direction from nibbling The 1st extension that syncephalon portion extends, the stage portion configured deviously from the 1st upward leg side of extension and from the step Portion by than the 1st extension close to the upper leg in a manner of the 2nd extension that extends along zipper width direction.Also, for Each chain tooth, since lower leg has stage portion, to have the zipper that can store for the lower section for being formed in the 2nd extension to install structure Storage space portion of the tooth chain of part with mounting portion, lower surface of the storage space portion with the 1st extension from lower leg to the 2nd The height dimension of the lower surface of extension.

Tooth chain band of the invention is being accommodated in the tooth chain band mounting portion of zipper installation component (such as cloth) as a result, The state of spatial portion received is installed on tooth chain band mounting portion come when producing product, can utilize and prolong from the 1st of the lower leg of chain tooth The lower surface of extending portion to upper leg upper surface height dimension by tooth chain band it is whole be ensured to be a certain constant highly stablely Size.

At the same time, even if zipper installation component (cloth) has multi-thickness, the storage space of chain tooth can also be utilized Portion absorbs the thickness of zipper installation component, makes the height of the upper surface of the upper leg from the lower surface of zipper installation component to chain tooth Size is reduced to the height dimension of the upper surface from the lower surface of the 1st extension of the lower leg of chain tooth to upper leg (that is, tooth chain With whole height dimension) below.

Thus, the interval between upper flange and lower wing plate is being set as a kind of pull head of a certain prescribed level can slide When dynamic mode is installed on the chain denture by the chain dentification of tooth chain band of the invention, even if the thickness of such as zipper installation component It is relatively thin, also the height of tooth chain band entirety can be ensured to be constant using the upper leg of chain tooth and the 1st extension of lower leg Size, therefore pull head is not easy to shake in pull head sliding.

On the other hand, it even if the thickness of such as zipper installation component is thicker, can also be inhaled using the storage space portion of chain tooth The thickness for receiving the zipper installation component prevents the height dimension of tooth chain band entirety to be greater than described such prolong from the 1st of lower leg The lower surface of extending portion to upper leg upper surface constant height dimension.Thereby, it is possible to be effectively prevented slide pull head When chain tooth, zipper installation component crimped with the upper flange of pull head, lower wing plate, zipper installation component insertion pull head, therefore can be steady Surely ensure the brisk of pull head and smoothly slide.Also, the sewing line for sewing chain tooth is also not easy strongly to contact with pull head, because This also can solve the easily broken such problems of sewing line.

In such tooth chain band of the invention, from the lower surface of the 1st extension of the lower leg of chain tooth to the 2nd extension Lower surface height dimension be set to the upper surface from the lower surface of the 1st extension to upper leg height dimension 5% Above and 25% or less.Thereby, it is possible to tooth chain band of the invention is kept being installed in stable conditionly for appropriate posture with chain tooth The tooth chain band mounting portion of zipper installation component, also, when tooth chain band is installed on zipper installation component, the receipts of chain tooth can be utilized Spatial portion of receiving suitably absorbs the thickness of zipper installation component.Moreover, after forming zipper, the chain tooth of the posture of chain tooth in pull head It is not easy to tilt in path of navigation.

Also, in tooth chain band of the invention, the 2nd of upper leg and lower leg the is extended by the double-locked stitch of sewing line Portion sews in chain tooth fixing component.As a result, when carrying out sewing of the chain tooth relative to chain tooth fixing component, can efficiently by Chain tooth fixing component is fixed in the upper leg of chain tooth and the sewing of lower leg, therefore can be realized the raising of productivity.Also, pass through Upper leg and lower leg can be stably attached to chain tooth fixing component by the double-locked stitch of sewing line, moreover, even if for example Sewing line is also not susceptible in the case where sewing thread breakage to burst at the seams.

In particular, in this case, the looper thread of the sewing line of double-locked stitch is carried out with across the side of the upper leg of chain tooth Formula configuration.Also, the needlework of the sewing line pierce through chain tooth between adjacent chain tooth and fix across the 2nd extension of lower leg Component, and interlock with looper thread.As a result, in the tooth chain band mounting portion that tooth chain band of the invention is installed on to zipper installation component When, the needlework of zipper installation component covering protection sewing line can be utilized.The needlework of sewing line are not exposed to outer substantially as a result, Therefore portion compared with the looper thread of the sewing line across the upper leg of chain tooth, is less susceptible to be cut off, can more efficiently prevent from Sewing line bursts at the seams.

In addition, as chain tooth fixing component, being able to use the band structure including braiding tissue in tooth chain band of the invention Part, the band member including warp knitting fabrics, band member formed by non-woven fabrics covers. or plastic film structural component.Pass through utilization Such band member or film structural component form chain tooth fixing component, so as to draw chain tooth fixing component with simple construction Be difficult to stretch on chain length direction, thereby, it is possible to stably keep the clipping room of the chain tooth of tooth chain band away from.

Also, the cross section of such band member or film structural component has the size on thickness direction smaller and width direction On larger-size flat shape, therefore band member or film structural component can be made easily through in the leg up and down of chain tooth Between.Also, the leg up and down of chain tooth is being sewed when on band member or film structural component using such as sewing machine, can make to sew Eedle steadily pierces through band member or film structural component, can successfully carry out sewing operations.

In addition, for zipper provided by the invention and with zipper article, with the structure without zipper strip tooth chain band with The tooth chain of zipper installation component is installed on tooth chain band mounting portion with the state that mounting portion is accommodated in storage space portion.Also, it draws Head is installed on the chain denture by chain dentification in a manner of it can slide.

For being configured to such without zipper strip zipper and with zipper article, chain tooth sewing is fixed in such chain tooth On component, therefore, even if not using member of formation of the zipper strip as zipper, the clipping room of chain tooth can be also stably kept Away from.

That is, in the present invention, it can be steadily by the clipping room of chain tooth away from prescribed level be remained, it at the same time, can The zipper strip of the previous required member of formation as zipper is omitted, therefore can be realized the lightweight of zipper, cost cutting.

Moreover, in the case where constituting zipper with omitting zipper strip, it can be by tooth chain band to be for example bent into bending etc. Be installed on zipper installation component in stable conditionly.Also, zipper present in previous zipper in this case, will not occur Band heave, be recessed or ripple shape pleat the problems such as, therefore can be improved the aesthetics (exterior quality) with zipper article.

Moreover, the height gauge of upper surface of the lower surface from the 1st extension of the lower leg of chain tooth to upper leg can be utilized It is very little that tooth chain band entirety is ensured to be a certain constant size highly stablely, at the same time, even if zipper installation component (cloth Material) tooth chain band mounting portion there is multi-thickness, as long as the tooth chain has with mounting portion from the 1st extension of the lower leg of chain tooth Lower surface to the lower surface of the 2nd extension height dimension thickness below, it will be able to can using the storage space portion of chain tooth Thickness of the tooth chain with mounting portion is absorbed by ground.

Even if pull head is in cunning as a result, in the case where the tooth chain of such as zipper installation component is with the thinner thickness of mounting portion It is also not easy to shake when dynamic, also, even if also can in the case where thickness of the tooth chain of zipper installation component with mounting portion is thicker Steadily ensure the brisk of pull head and smoothly slides.

In this case, the height dimension of chain tooth 20 is the upper surface from the lower surface of the 1st extension 23a to upper leg Height dimension A, such as it is set as lower surface and the bottom wing of the central divider 33a for being formed in aftermentioned upper flange 33 than pull head 30 Interval between the upper surface of plate 34 is small.In addition, the height dimension A of the chain tooth 20 is preferably set to prevent left and right chain tooth 20 from existing The size shaken in the up-down direction in the chain tooth path of navigation of pull head 30, such as be set as under the central divider 33a 85% or more the size at the interval between surface and the upper surface of lower wing plate 34.

In addition, the storage space portion 25 of chain tooth 20 has under the lower surface to the 2nd extension 23c of the 1st extension 23a The height dimension C on surface, the height dimension in the storage space portion 25 is (that is, from the lower surface of the 1st extension 23a to the 2nd extension The height dimension of the lower surface of 23c) C be set as chain tooth 20 height dimension A 5% or more and 25% size below.

The height dimension C in storage space portion 25 is 5% or more of the height dimension A of chain tooth 20, if also, using specific value It indicates, the height dimension C in storage space portion 25 is 0.1mm or more, and the size so as to suitably ensure storage space portion 25 is (high Degree), when tooth chain band 1 being installed into cloth 5 as described later, cloth 5 is accommodated in storage space portion 25, can be utilized down The stage portion 23b of leg 23 absorbs the thickness of cloth 5.

Absorption mentioned here refers to, due to the height dimension C in storage space portion 25, the conjunction of the thickness of size B and cloth 5 Meter is no more than size A, or even more than, the size for being more than also very little.That is, referring to that the thickness of cloth 5 is removed and becomes In other words the case where using the height dimension A of chain tooth 20 as benchmark, refers to that the thickness of cloth 5 is not added in height dimension A simply On, and be included in the height dimension C in storage space portion 25, it is equipped with so that the thickness of cloth 5 will not be embodied directly in In the overall height dimension of the chain tooth 20 of cloth 5.In addition, in other words the state being accommodated in storage space portion 25 refers to, as The tooth chain of the cloth 5 of zipper installation component is with the edge of mounting portion 5a to separate in zipper width direction with stage portion 23b The state of the state installation of ground configuration.

As described, the thickness of cloth 5 is absorbed using the stage portion 23b of lower leg 23, thus, foring zipper 3 When, tooth chain band 1 is not easy to touch the aftermentioned upper flange 33 of pull head 30 and lower wing plate 34 simultaneously, therefore is able to suppress the cunning of pull head 30 Dynamic resistance becomes larger, and trippingly carries out the slide of pull head 30.Also, it is not susceptible to chain tooth 20 being sewn to chain tooth fixing component 14 On the 1st sewing line 13 and the 2nd sewing line 6 that tooth chain band 1 is sewn on cloth 5 the case where rubbing and be broken with pull head 30.Separately Outside, the aftermentioned needlework 13b of the 2nd extension 23c across lower leg 23 of the 1st sewing line 13 is covered by cloth 5, therefore the needlework 13b is without exposure to outside.

On the other hand, the height dimension C in storage space portion 25 be chain tooth 20 height dimension A 25% hereinafter, so as to Enough prevent the 2nd extension 23c of lower leg 23 too close to upper leg 22.Thereby, it is possible to reliably ensure the 2nd of lower leg 23 the Interval between extension 23c and upper leg 22 inhibits chain tooth fixing component 14 excessively to be flattened, prevents chain tooth fixing component 14 It is bent on both forward and reverse directions, is uneven.Also, prevent form zipper 3 at present leg 23 the 2nd extension 23c (or Cloth 5) and the aftermentioned lower wing plate 34 of pull head 30 between interval it is excessive.As a result, when engaging left and right chain denture 11, in pull head The posture of chain tooth 20 is not easy to tilt in 30 aftermentioned chain tooth path of navigation, therefore can prevent to engage bad situation.

In addition, in the present invention, for the 2nd extension of the height dimension A of chain tooth, the upper surface of upper leg and lower leg Size, the ratio of each sizes such as the height dimension C of height dimension B and storage space portion 25 between the lower surface of 23c, energy Enough consider that the size of tooth chain band, type, the thickness of zipper installation component that install tooth chain band etc. are arbitrarily decided, here, as The specific size of each size of the tooth chain band 1 of the present embodiment 1 is introduced in an example.

In the tooth chain band 1 of the present embodiment 1, the height dimension A of chain tooth 20 is set as 2.6mm, the width dimensions of chain tooth 20 (that is, size on one end slave 21 side of engageable head of chain tooth 20 to the left and right directions of the other end of 24 side of linking part) D setting For 4.9mm.In addition, the height dimension B between the lower surface of the 2nd extension 23c of the upper surface of upper leg 22 and lower leg 23 It is set as 2.1mm, the height dimension C in storage space portion 25 is set as 0.5mm.

In turn, in the present embodiment 1, in the width direction of chain tooth 20, prolong from the stage portion 23b of lower leg 23 with the 2nd The width dimensions E of ora terminalis of boundary portion between extending portion 23c to 24 side of linking part of chain tooth 20 is set as 2.8mm.In the situation Under, preferably width dimensions E is set as 20% or more and 70% size below of the width dimensions D of chain tooth 20.

Width dimensions E is 20% or more of the width dimensions D of chain tooth 20, so as to using after the 1st sewing line 13 It states double-locked stitch chain tooth 20 is steadily sewn in chain tooth fixing component 14.Also, width dimensions E is the broad-ruler of chain tooth 20 Very little D 70% hereinafter, the 1st extension 23a so as to reliably ensure lower leg 23 width dimensions, foring zipper Do not allow to be also easy to produce shaking of the chain tooth 20 relative to pull head 30 when 3.

Also, in the case where the present embodiment 1, as shown in Figures 2 and 4, in the state of after engaging left and right tooth chain band 1 Width dimensions, the i.e. institute of the ora terminalis of 24 side of linking part from the ora terminalis of 24 side of linking part of side chain tooth 20 to other side chain tooth 20 Meaning chain width dimensions F is set as 8.2mm.

To provide that the chain tooth fixing component 14 of the chain tooth 20 of the such the present embodiment 1 of spacing installation is used with braiding tissue Band member, it is preferable to use by more warp thread be plain weave group that one group of weft yarn is made by single layer by two single thread doublings The band member knitted.Such band member being made into as plain weave have on thickness direction size is smaller, in width direction Larger-size flat cross-sectional shape, and warp thread is worked out using weft yarn and there is stretching on zipper length direction What contracting was suppressed is not easy flexible construction.In addition, a side edge part of the band member is formed with ear, which is by by suitable Sequence hooks next weft yarn and links up wire loop reflexing end and formed.

In addition, as chain tooth fixing component 14, other than described be made into as the band member of plain weave, additionally it is possible to make With band member, band member formed by non-woven fabrics covers. or the conjunction having in warp knitting fabrics of each stringer configured with Chain knitted yarns At the film structural component etc. of resin.

Such chain tooth fixing component 14 is configured to zipper width direction (also referred to as bandwidth side in the non-loaded state To) on size be tape thickness direction on size 2 times or more size, more preferably, the zipper of chain tooth fixing component is wide 2.5 times or more and 3.5 times of sizes below of the size on tape thickness direction are dimensioned on degree direction.

Here, no load condition refers to, extracts chain tooth fixing component 14 out without to the chain tooth fixing component from chain tooth 20 14 apply the state for the artificial external force such as stretching, compressing.Chain tooth fixing component 14 has such size, is drawing to have Flexible construction is not easy on chain length direction.

In addition, as chain tooth fixing component 14, such as it is also contemplated that the upper leg 22 of chain tooth 20 and lower leg 23 it Between insertion be referred to as the core wire of so-called kernmantle (Japanese: ニ ッ ト U ー De), which is by the shape of threads boundling Obtained from being worked out around it under state.But for making the bundles of kernmantle of threads, threads edge like this Zipper length direction extends, and each yarn has fluctuating (curling) in zipper width direction and zipper thickness direction, therefore is easy to stretch Contracting, so being not suitable for use in chain tooth fixing component 14.

In addition, there is the chain tooth fixing component 14 of flat pattern using cross section, so as to hold in the present embodiment 1 Changing places makes chain tooth fixing component 14 between the leg up and down 22,23 of chain tooth 20, and is using sewing machine as described later When upper and lower leg 22,23 is sewn in chain tooth fixing component 14, also needle can be made steadily to pierce through chain tooth fixing component 14, sewing operations can be carried out successfully.

Then, the method for the tooth chain band 1 for manufacturing described the present embodiment 1 is illustrated.

Firstly, the chain tooth 20 of forming the present embodiment 1.Such as by the monofilament of the thermoplastic resins such as polyamide, polyester to roll up After helically wound mode shapes, chain tooth fixing component 14 is inserted into along chain tooth length direction (zipper length direction) and is shaped Between good upper leg 22 and lower leg 23.At this point, chain tooth fixing component 14 is with the one end of its width direction and chain tooth 20 The mode that linking part 24 contacts is inserted into chain tooth 20.

Then, in the state of being sandwiched in chain tooth fixing component 14 up and down between leg 22,23, by hot pressing etc. by lower leg The prescribed portion by 24 side of linking part in portion 23 is pressed towards upper leg 22, forms stage portion 23b in lower leg 23.This When, by pressing lower leg 23, chain tooth fixing component 14 is clamped into (holding) in upper leg 22 and the 2nd of lower leg 23 Between extension 23c.The chain tooth 20 of the present embodiment 1 is shaped as a result,.

Then, it for the chain tooth 20 obtained like this, is held in the chain tooth fixing component 14 contacted with linking part 24 In the state of between upper leg 22 and the 2nd extension 23c of lower leg 23, using the sewing machine of chain tooth sewing, the 1st seam is utilized 2nd extension 23c of upper leg 22 and lower leg 23 is individually fixed in chain tooth fixing component 14 by the double-locked stitch of line 13 processed Surface and the back side.The tooth chain band 1 of the present embodiment 1 of Fig. 3~as shown in Figure 5 is produced as a result,.

In this case, the looper thread 13a (Japanese: ル ー パ yarn) of the 1st sewing line 13 of double-locked stitch is carried out in chain tooth The surface side of fixing component 14 directly contacts with the upper leg 22 of chain tooth 20 and across leg 22 on this.Also, the 1st sewing line 13 Needlework 13b the back side of chain tooth fixing component 14 directly contacted with the 2nd extension 23c of the lower leg 23 of chain tooth 20 and across The 2nd extension 23c is crossed, and pierces through chain tooth fixing component 14 between chain tooth 20 adjacent to each other, and in chain tooth fixing component The looper thread 13a that 14 surface side passes through interlocks.

Stitch, and the 1st sewing unit formed by the double-locked stitch of the 1st sewing line 13 are formed between each chain tooth 20 as a result, Be formed as exposing in the surface side and back side of chain denture 11.In addition, the 2nd of the 1st extension 23a long of ratio of lower leg 23 the is prolonged The part of extending portion 23c is sewed to chain tooth fixing component 14, therefore can steadily carry out sewing process.

Chain tooth 20 is fixed on using the double-locked stitch of the 1st sewing line 13 like this and is not easy to stretch on zipper length direction Chain tooth fixing component 14, thus chain tooth fixing component 14 can as chain tooth fixing component keep chain tooth 20 shape, and The clipping room of chain tooth 20 is remained away from (in other words, the interval between engageable head 21) constant.

Also, the 1st sewing line 13 pierces through 14 ground of chain tooth fixing component and keeps chain tooth 20, therefore the 1st sewing line 13 is in chain tooth The perforation position of fixing component 14 is less likely to occur to misplace, and can securely fix the upper leg 22 of chain tooth 20, lower leg 23 It is supported on the specified position of chain tooth fixing component 14.Therefore, leg 22, lower leg 23 can be prevented relative to the fixed structure of chain tooth Part 14 is mobile.

Moreover, the intensity of stitching is good when the stitching form as the 1st sewing line 13 uses double-locked stitch, therefore preferably, In this way, being also less likely to occur the 1st sewing line 13 even if the 1st sewing line 13 is broken and bursting at the seams.Also, it will be made into using double-locked stitch Band member 14 and chain tooth 20 it is stitched together, so as to high production rate manufacture without zipper strip tooth chain band 1.

Also, it is known usually to sew chain tooth in the case where zipper strip in the double-locked stitch using sewing line, if sewing The needlework of line are cut off, and compared with the situation that the looper thread of sewing line is cut off, are easy the sewing unit (sewing in sewing chain tooth Line) it bursts at the seams.

In this regard, especially in the present embodiment 1, the needlework 13b of the 1st sewing line 13 of double-locked stitch is carried out with across lower leg The mode of the 2nd extension 23c in portion 23 sews chain tooth 20.That is, will be cut-off when sewing unit be easy to happen the needlework 13b to burst at the seams and match It sets in lower 23 side of leg, thus when the sewing of tooth chain band 1 of the present embodiment 1 is formd zipper 3 in cloth 5, needlework 13b's Exposure surface side is covered and be protected by cloth 5, therefore needlework 13b is not easy directly from external force, and needlework 13b is not easy It is cut off.

The 1st sewing unit that the double-locked stitch of the 1st sewing line 13 sewed as a result, by carry out chain tooth 20 is formed is more difficult to be opened Line, therefore it is able to extend the service life of tooth chain band 1 and zipper 3.

In addition, in the present invention, the stitching form of the 1st sewing line 13 can also use other than the double-locked stitch of flush joint etc. Mode.

The tooth chain band 1 of the present embodiment 1 produced like this is not to use as composition necessary to previous tooth chain band The mode of the zipper strip of component is formed, thus compared with previous tooth chain band light weight and manufacturing cost can be inhibited compared with It is low.

In turn, chain tooth 20 is sewed in the chain tooth fixing component for being not easy flexible construction on zipper length direction 14, therefore even if not using zipper strip, can also be stably kept using chain tooth fixing component 14 clipping room of chain tooth 20 away from.And It, will not be as the previous tooth chain band with zipper strip and even if the tooth chain band 1 of the present embodiment 1 bends to bending etc. It generates the heaving of zipper strip, be recessed or undulatory pleat.

In addition, as shown in FIG. 6 and 7, the tooth chain band 1 of the present embodiment 1 relative to the cloth 5 as zipper installation component into It has gone in the state of contraposition, has been stitched with sewing machine 40 using the flush joint of the 2nd sewing line 6 using tooth chain band sewing as shown in Figure 8 System is fixed on cloth 5.In this case, as cloth 5, the lower surface from the 1st extension 23a with chain tooth 20 to is used The cloth of the size thickness below of the height dimension C of the lower surface of 2 extension 23c.

In addition, when carrying out the sewing process of tooth chain band sewing sewing machine 40, due to the chain tooth 20 in the present embodiment 1 Lower leg 23 is equipped with stage portion 23b, thus when carrying out the position alignment of tooth chain band 1 relative to cloth 5, it can be by the stage portion 23b is used as the benchmark of positioning, and can be effectively prevented the cloth 5 crosses stage portion 23b and is exposed to lower leg 23 the 1st and prolong The side extending portion 23a (too close to 21 side of engageable head).

In addition, stage portion 23b is equipped in the lower leg 23 of chain tooth 20, so as to readily recognize the positive and negative of tooth chain band 1 Direction, therefore can prevent tooth chain band 1 with the direction opposite with both forward and reverse directions (that is, the court that upper leg 22 is contacted with cloth 5 To) sewing fault as cloth 5.The effect is especially being implemented the processing such as colored, printing to tooth chain band 1, is being total to cloth 5 Become important in the case where particular design with performance product.

In addition, in the present embodiment 1, chain tooth 20 and chain tooth fixing component 14 are in the zipper whole length direction all by the 2nd Sewing line 6 is sewed in cloth 5.2nd sewing line 6 across the upper leg 22 of chain tooth 20 and the 2nd extension 23c of lower leg 23, And chain tooth fixing component 14 and cloth 5 are pierced through between adjacent chain tooth 20, to sewing tooth chain band 1 in cloth 5.

In the present embodiment 1, the tooth chain band 1 carried out using the sewing of tooth chain band with sewing machine 40 is as follows to the sewing of cloth 5 It states and is performed such that as shown in figure 8, tooth chain band 1 to be accommodated in the recess portion of the lower plate 42 of sewing machine, by the cloth 5 of left and right phase each other The lower leg of the upper plate 41 Yu tooth chain band 1 that are formed in sewing machine is configured at mounting portion 5a (opposite side edge) to the tooth chain of configuration Gap between 23 the 2nd extension 23c.

In this case, the sewing of the flush joint of the 2nd sewing line 6 use tylostyle (Japanese: ボ ー Le Port イ Application ト needle) as Needle 43 carries out.The tylostyle be front end be spherical shape needle, the diameter of front end be preferably 0.2mm or more and 0.6mm or less.

Tylostyle is used like this, even if so that needle 43 collides with chain tooth 20 in sewing, tylostyle Position also relative misalignment and can pierce through chain tooth fixing component 14 and zipper installation component (cloth in the longitudinal direction along chain tooth 20 Material) 5, therefore damage and the losing of needle, the bending etc. that can be avoided chain tooth 20 makes to sew process smoothly and steadily It carries out.

Moreover, the stitching form of the 2nd sewing line 6 uses flush joint, it is not easy so as to obtain the stitch of the 2nd sewing line 6 It unlocks, the advantage that intensity is good, also, even if tylostyle and chain tooth 20 collide and the position of tylostyle when sewing (in other words, the position of needle-penetration chain tooth fixing component 14 and cloth 5) shifts, also can be smooth by tooth chain band 1 and cloth 5 And it steadily sutures.

In addition, when being sewed using such 2nd sewing line 6, the case where collision has occurred in tylostyle and chain tooth 20 Under, for the tooth chain band 1 of the present embodiment 1, chain tooth 20 is validly fixed on chain tooth fixing component 14 as described, therefore can Allow chain tooth 20 slightly to move to avoid tylostyle, and the spacing of the chain tooth 20 kept by chain tooth fixing component 14 can be prevented Unevenly.

In addition, in the present embodiment, (especially the 2nd sewing line 6 exists the 2nd sewing unit that the flush joint of the 2nd sewing line 6 is formed The part exposed in chain denture 11) it is configured to overlap onto the double-locked stitch formation of the 1st sewing line 13 in zipper width direction Within the scope of the formation of 1st sewing unit.Herein, the 2nd sewing unit is located within the scope of the formation of the 1st sewing unit and refers to, is formed on chain The 2nd sewing unit on the surface (upper surface of the upper leg 22 of chain tooth 20) of denture 11 is configured in the table for being formed on chain denture 11 The 1st sewing unit on face (upper surface of the upper leg 22 of chain tooth 20) in the range on bandwidth direction.

In addition, in chain denture 11 formed the 2nd sewing unit the 2nd sewing line 6 from the lower leg 23 of adjacent chain tooth 20 it Between by piercing through chain tooth fixing component 14, then, from passing through between the upper leg 22 of adjacent chain tooth 20 and pierce through cloth 5. In this case, a part of the 1st sewing line 13 also has the upper surface of the upper leg 22 positioned at the 2nd sewing line 6 and chain tooth 20 Part between top.

By implementing above such sewing process carried out by the sewing of tooth chain band with sewing machine 40, by chain tooth 20, chain tooth 2nd sewing unit of the part of fixing component 14 and cloth 5 to be clipped in as the 2nd sewing line 6 in chain denture 11 and it is exposed at cloth Mode between the part of the 2nd sewing line 6 on the surface of material 5 is sutured, is fixed.In this case, as described, the 2nd seam In the range of 2nd sewing unit of line 6 processed is formed as overlapping onto the 1st sewing unit of the 1st sewing line 13, to keep the 2nd sewing unit mixed It is not easy to be noted in the 1st sewing unit, therefore can be improved the aesthetics for being mounted with the article of tooth chain band 1.
