Background technology

Real opening put down in the 4-84313 communique (patent documentation 1) in Japan; Following training pants (training trousers) is disclosed: in order can under dress is raced with states such as footwear, spikes, to put on training pants and can to take off at once; Shank has been installed slide fastener in the left and right sides, thereby can be opened into sheet portion of predecessor and back body sheet portion.

About this patent documentation 1 disclosed training pants, more specifically explanation is shown in figure 19, in the left and right sides of training pants 60, in the scope of the bottom of bottom of s trouser leg side, the slide fastener 61 that can open and close is installed in the upper end from the waist side of this training pants 60.Therefore, the pull head 62 through making each slide fastener 60 slides and the chain denture that will be in engagement is separated, thereby can training pants 60 be opened into sheet portion of predecessor 63 and back body sheet portion 64 from the form of trousers.

In addition; The sheet portion of predecessor 63 of the state of opening like this and obtaining and back body sheet portion 64; Be bonded thereby the chain denture of mutual correspondence is engaged with each other, so can training pants 60 be returned to trousers form shown in Figure 19 through pull head 62 slips that make said slide fastener 61.

Training pants 60 with patent documentation 1 of such structure under the blocking of the slide fastener 61 of the left and right sides, can likewise be put on, take off with existing common training pants 60.In addition, this training pants 60 is opened sheet portion of predecessor 63 and back body sheet portion 64 through slide fastener 61, even under dress is raced with states such as footwear, also can easily take off.

But slide fastener just uses in the goods in various fields all the time, in addition, slide fastener self also according to the goods that will use improve, thereby have various functions.For example; Following slide fastener is disclosed in the special public clear 41-9266 communique of Japan (patent documentation 2): the upper end side of chain denture preceding sign indicating number is installed and pull head is slided and make pull head along the chain denture in the past the sign indicating number side break away from, can not rely on thus pull head slidably with about the chain denture in the past the sign indicating number side separate.

The slide fastener that this patent documentation 2 is put down in writing is commonly called the top-opening type slide fastener, even as existing common slide fastener, pull head is slided, and through with about zipper teeth chain pull to the direction that is separated from each other, also can the chain denture be separated and unziped.Therefore, the top-opening type slide fastener for example uses in the goods of that kind such as life vest of reply when urgent fast.

And, put down in writing in this patent documentation 2 with the top-opening type slide fastener in the relevant invention of preceding sign indicating number used.This patent documentation 2 is put down in writing preceding sign indicating number, shown in figure 20, have before the 1st on the zipper teeth chain 73 that is fixed on the left side yard portion 75 before the 2nd in yard portion 74 and the zipper teeth chain 73 that is fixed on the right side with relative mode each other.

Yard portion 74 has the through hole 76 that on band table back of the body direction, connects before the 1st, and constitutes by yard portion 75 before the 2nd and push and can strain.Yard portion 75 before the 2nd has the jut 77 and the protrusion 78 that are configured on the side wall surface relative with the other side's zipper strip, and constitutes and can push the 1st preceding yard portion 74 through protrusion 78.

Slide fastener 71 with so preceding sign indicating number; Through making pull head 72 to the engagement direction of chain denture (among the figure; Last direction) slides; Make that yard portion 74,75 gets into from the shoulder mouth of pull head 72 respectively before the 1st and the 2nd, so before the 1st before yard portion 74 and the 2nd yard portion 75 mutual butts and be urged pull head 72 about flange 72a on, thereby pull head 72 is stopped in the position of stipulating.

Then, through from the halted state of pull head shown in Figure 20 72 with pull head 72 to the powerful pull-up in top, yard portion 74,75 is urged and approaching each other before the 1st and the 2nd.At this moment, before the 1st yard portion 74 by the protrusion 78 of yard portion 75 before the 2nd from side wall surface thruster pressure and strain, thereby yard portion 74,75 can be through pulling out between the left and right sides flange 72a of pull head 72 and from the deutostoma of this pull head 72 before the 1st and the 2nd.

Thus, pull head 72 can be crossed the 1st and the 2nd preceding yard portion 74,75, and moves to the upper side of yard portion 74,75 before the 1st and the 2nd, and the chain denture in left side is pulled out from the chain tooth path of navigation of pull head 72.Therefore, through after with about zipper teeth chain 73 draw back to the direction that is separated from each other, the chain denture about can making is separated from upper side, thus can not rely on pull head 72 open slide fastener 70 slidably rapidly and easily.

On the other hand, disclose following technology in the japanese kokai publication hei 6-14806 communique (patent documentation 3): a kind of slide fastener that in automotive seat etc., uses can make pull head from the pull-off of slide fastener long-chain after the chain denture engagement about making.

In the slide fastener 81 that this patent documentation 3 is put down in writing, shown in figure 21, about distolateral being equipped with of chain denture before sign indicating number 82, at another distolateral back sign indicating number 83 that is equipped with.Sign indicating number 82 has before said: be fixed on the zipper strip in left side, have engaging recessed part the 1st before yard portion 84; With on the zipper strip that is fixed on the right side, have engaging protrusion the 2nd before yard portion 85.

In addition; Should be set at by preceding sign indicating number 82; Embed in the engaging recessed part of yard portion 84 before the 1st and before making the 1st and the 2nd during the mutual fastening of yard portion 84,85 in the engaging protrusion that makes yard portion 85 before the 2nd, gauge that preceding sign indicating number 82 is whole and width dimensions be be in engagement about identical gauge and the width dimensions of slide fastener coupling element.Thus, when making before the 1st and the 2nd 84,85 fastenings of yard portion, not shown pull head can be easily through preceding sign indicating number 82, so can make pull head from the pull-off of slide fastener long-chain.

And, in the slide fastener 81 of patent documentation 3, the band upper end 86 that disposes preceding sign indicating number 82 of zipper strip, the band portion of its left and right sides is excised, and forms the mountain shape with the outstanding mode of band portion of the central authorities of sign indicating number 82 before having.Band portion through making the central authorities with preceding sign indicating number 82 like this is outstanding; The slide fastener 81 of the state after the pull head pull-off (slide fastener long-chain) is when receiving lateral pull; Sign indicating number 82 before can making this lateral pull be difficult to act on is so can stably keep the blocking of yard portion 84,85 before the 1st and the 2nd.

Patent documentation 1: real the opening of Japan put down the 4-84313 communique

Patent documentation 3: japanese kokai publication hei 6-14806 communique

Left and right sides shank at the training pants 60 of patent documentation 1 record; As previously mentioned; Upper end from the waist side is equipped with slide fastener 61 in the scope of the bottom of bottom of s trouser leg side; Make pull head 62 slips of this slide fastener 61 and separate into 2 zipper teeth chains, thus, can training pants 60 be split up into sheet portion of predecessor 63 and back body sheet portion 64.

Particularly, in the training pants 60 of patent documentation 1,, the grafting-separate pieces of slide fastener 61 is configured in the bottom of bottom of s trouser leg side, preceding sign indicating number 82 is configured in the upper end of waist side for easy operating slide fastener 61.Therefore, when keeping the form of trousers in the chain denture engagement that makes slide fastener 61, the pull head 62 of slide fastener 61 is configured in the waist of the upper end that becomes the chain denture.

Generally speaking, the training pants clothes with retractility that use form more.In addition, when putting on training pants or it is taken off, the waist portions of training pants is stretched.Therefore; As the training pants 60 of patent documentation 1 when for the trousers form pull head 62 be disposed under the situation of waist; All can to waist apply the tension force of waistline direction when wearing off training pants 60 at every turn, applied big lateral pull repeatedly so dispose the upper end of the slide fastener 61 of pull head 62.

At this moment; Under the situation of the so-called free pull head of after use on this slide fastener 61 does not for example have, stating 62 that stops pawl; Because the leading section of slide fastener 61 receives lateral pull when wearing off training pants 60; So via about the chain denture effect has the stress that makes chain denture detaching direction (below) to pull head 62, cause the easy slip that becomes on the contrary mutually of this pull head 62 and user's wish.Therefore, existing in chain denture about the leading section of slide fastener 61 separates and can't keep this problem of trousers form.

In addition, receive lateral pull and under the situation of sliding, pull head 62 keeps sliding unreasonably with respect to the posture that the chain denture tilts sometimes at pull head 62 like this.At this moment, the powerful collision of the slide fastener coupling element of the deutostoma of pull head 62 and chain denture, meanwhile pull head 62 forces downwards mobile, so this slide fastener coupling element takes place sometimes by the deutostoma of pull head 62 this problem of pruning.

On the other hand; As slider for slide fastener; Except above-mentioned free pull head 62; Use the pull head of band auto-stop mechanism all the time: it possesses with respect to what chain tooth path of navigation can get into, withdraw from and stops pawl, pull head is stopped in the desirable position of chain denture and keeps.

Can consider, the pull head of this band auto-stop mechanism is used in the training pants 60 of patent documentation 1 and the pull head that prevents above-mentioned that kind is thus forced the situation of sliding downwards.But the lateral pull of leading section that when wearing off training pants 60, acts on slide fastener 61 is big, so only stopped the pawl fastening on the chain denture through as in the past, making, is difficult to stably keep the halted state of pull head.

Particularly, under the situation of the pull head that has used the band auto-stop mechanism, even the position of the upper end of sign indicating number before pull head being slided into dispose also can make the pull head stop in the desirable position of chain denture.But; When wearing off training pants under the state of the upper end position that for example sign indicating number is disposed before pull head not being moved to; Pull head is become to slide easily; So with the situation of above-mentioned free pull head 62 likewise, generation can't keep this problem of form of trousers.

And; Under the situation of the pull head that has used the band auto-stop mechanism; Stopping under the state that pawl is projected into chain tooth path of navigation, pull head slides to the detaching direction of chain denture unreasonably, so slide fastener coupling element can be pruned by the deutostoma of pull head; And slide fastener coupling element also can be stopped pawl and prune, and also exists the breakage of slide fastener coupling element to become big this problem.

In addition; In order lateral pull to be difficult to act on the leading section of slide fastener 61; Can consider that also that kind of for example said patent documentation 3 records is with the part excision of the left and right sides in the strap end portion of zipper strip and make this strap end portion form the mountain shape.

But, even the strap end portion of zipper strip is formed the mountain shape, when wearing off training pants 60, also can't make lateral pull not act on the leading section of slide fastener, run counter to user's wish this problem of arbitrarily sliding so can't eliminate pull head 62.And, under this situation, can new produce zipper strip self easily from this problem of cut-out fracture of band upper end, form concavo-convex and make exterior quality reduce this problem in the waist portions of training pants 60.

Under this situation, preferably, said sewing line also have from the said the 1st make portion an end form continuously the 2nd make portion, the said the 2nd makes portion with respect to said the 1st portion of making tilted configuration at a predetermined angle.

The effect of invention

In the slide fastener of the present invention, have at the preceding sign indicating number of a distolateral installation of the chain denture of a side zipper strip: be connected to pull head shoulder oral-lateral end the 1st before yard part; And be configured in before the 1st between yard part and chain denture and be connected to the 2nd preceding yard part of deutostoma side end of the guide post of pull head.In addition, before the 2nd yard part from flange sliding-contact edge portion to opposite side edges portion till the full-size of bandwidth direction set for, bigger than guide post in the chain tooth path of navigation of pull head and the interspersed width between the flange.And at least a portion of the 2nd preceding yard part constitutes, can be with the mode strain of shrinking at bandwidth direction.

At this, the shoulder oral-lateral end of so-called pull head is meant the end of at least 1 shoulder oral-lateral in guide post, upper flange, lower wing plate and the flange of pull head.The flange sliding-contact edge portion of yard part is before the so-called the 2nd; Yard part is when the shoulder mouth of pull head has entered in the chain tooth path of navigation before the 2nd; With the flange sliding-contact of pull head the 2nd before the side edge part (side surface part) of yard part; State after for example yard part has before the 2nd under the situation of such fixed part and extension, the side edge part of square side becomes the flange sliding-contact edge portion of yard part before the 2nd in the band of fixed part.

In addition; The opposite side edges portion of yard part is the end edge portion (side surface part) of yard part and zipper teeth chain opposite side the other side before the 2nd before the so-called the 2nd; Yard part has under the situation of fixed part and extension before the 2nd, and the side edge part of the band foreign side side of extension becomes the opposite side edges portion of yard part before the 2nd.And, the interspersed width between the guide post of so-called pull head and the flange, the shortest air line distance of distance under the situation about linking with straight line till being meant from the sidewall of guide post to the internal face of flange.

Because the preceding sign indicating number in the slide fastener of the present invention; Has yard part before the preceding yard part of the 1st on the zipper teeth chain that is configured in a side and the 2nd as stated; Thereby before pull head is slided into during the position of sign indicating number, can make that yard part is connected to the shoulder oral-lateral end of pull head and pull head is stopped before the 1st.

In addition, the 2nd preceding yard part is when pull head slides into the position that is connected to yard part before the 1st, in the shoulder mouth entering chain tooth path of navigation of this pull head.At this moment; Since before the 2nd yard part from flange sliding-contact edge portion to opposite side edges portion till the full-size of bandwidth direction; Bigger than guide post in the chain tooth path of navigation of pull head and the interspersed width between the flange; So the 2nd preceding yard part makes at least a portion pass through strain on one side and in the bandwidth direction contraction, one side is passed through between the guide post and flange of pull head.

And when yard part is connected to the shoulder oral-lateral end of pull head as stated before the 1st or be about to before the butt, the part of the strain of yard part is recovered elasticity through guide post before the 2nd, and yard part is connected to the deutostoma side end of the guide post of pull head before the 2nd.Thus, can support the pull head that stops with the 1st preceding yard part butt reliably by the 2nd preceding yard part, thereby can stably keep the halted state of pull head.

Like this in slide fastener of the present invention; Through utilizing the strain of yard part before the 2nd, have the bandwidth direction bigger than the guide post of pull head and the interspersed width between the flange size the 2nd before yard part can be connected to the deutostoma side end of guide post and keep the halted state of pull head.Therefore, slide fastener of the present invention, only the zipper teeth chain through the folk prescription of sign indicating number before disposing just can make the slip of pull head stop in the precalculated position and keep this pull head.

And; In the slide fastener of the present invention; Yard part is because of recovering the deutostoma side end that elasticity is connected to the guide post of pull head before the 2nd, so yard part is connected to moment of the deutostoma side end of guide post the 2nd before, can give variation, the little contact sound of generation to the operation feeling of pull head.

Thus, for the user of slide fastener, can feel that the 2nd preceding yard part is connected to the deutostoma side end of guide post, thereby the halted state of confirming pull head is kept by the 2nd preceding yard part.Consequently; Can make the user that pull head is slided into and be connected to the operation of the stop position of yard part before the 1st, not slide until being connected to the unfavorable condition that yard part produces before the 1st so can significantly reduce owing to the user makes pull head.

In the slide fastener of the present invention, the said the 2nd preceding yard part has: be fixed on the fixed part on the zipper strip; With extend and be connected to the extension of the deutostoma side end of guide post from fixed part to band foreign side, said extension has the hole portion that connects in band table back of the body direction.Thus; Yard part can constitute on strain ground before can making the 2nd; So before pull head being slided into be connected to the 1st during yard part, yard part before the 2nd is got in the chain tooth path of navigation from the shoulder mouth of pull head, and make between interspersed swimmingly guide post of extension strain and the flange on one side.And then the extension of yard part is through after between guide post and the flange before the 2nd, and extension recovers elasticity, thereby can make extension be connected to the deutostoma side end of guide post and stably keep the halted state of pull head.

In addition; In the said patent documentation 2, put down in writing as previously mentioned can strain preceding sign indicating number part, but the preceding sign indicating number part of this patent documentation 2; Through with another of relative configuration before sign indicating number part butt and make sign indicating number part before 2 be pressed to pull head about flange on, and pull head is stopped.Relative with it, make the deutostoma side end of guide post that yard part before the of the present invention the 2nd is connected to pull head stably keeping the halted state of pull head, this with preceding yard part of patent documentation 2 in structure and use different fully.

Under this situation, said extension of the present invention constitutes, and has: with the 1st side wall surface of the relative configuration of the 1st preceding yard part; The 2nd side wall surface that is bent to form continuously from the 1st side wall surface; With form continuously from the 2nd side wall surface and make from sliding-contact edge portion to said opposite side edges portion till the 3rd side wall surface that reduces gradually towards said chain denture of the size of bandwidth direction.

Thus; When yard part is in the shoulder mouth entering chain tooth path of navigation of pull head before the 2nd; The 3rd side wall surface elder generation of extension and the guide post sliding-contact of pull head; So the inclination along the 3rd side wall surface can promote the strain of extension on one side,, interts between guide post and flange yard part Yi Bian easily being got in the chain tooth path of navigation.

Afterwards; Before the 2nd yard part from flange sliding-contact edge portion to opposite side edges portion till the guide post of size the best part through pull head of bandwidth direction; The extension of yard part recovers elasticity before the 2nd; Thus, the 2nd side wall surface of extension the 2nd side wall surface of the 1st side wall surface (particularly, lean on) is connected to the deutostoma side end of guide post and can stably keeps the halted state of yard part before the 2nd.

On the other hand; From pull head by the 2nd before the state that keeps of yard part; The operation pull head makes it mainly under the situation that the direction (detaching direction) that the engagement of chain denture is disengaged is slided; Because the 2nd side wall surface of extension forms agley, thus can make of the crooked sliding-contact of the guide post of pull head along the 2nd side wall surface of extension, while and promote the strain of extension that the 2nd preceding yard part got between guide post and the flange.Thus, can remove the state that pull head is kept by the 2nd preceding yard part, and pull head is slided to detaching direction.

In the slide fastener of the present invention, the chain denture has local at least 1 the frangible portion that lowers of engagement force of the chain denture about making.One distolateral in the chain denture of the opposing party's zipper strip; At least 1 pull head sliding-contact part is to dispose with the relative mode of preceding sign indicating number; The gauge of this pull head sliding-contact part is set for, and it is big at interval and littler than the interval of the upper and lower wing plate of pull head to intert the groove of groove than the band that forms in the pull head.In addition, the width dimensions on the bandwidth direction of this pull head sliding-contact part is set at following size: before the flange and the 2nd of the pull head the when pull head that can intert is held before the 2nd yard part between yard part.

Because pull head sliding-contact part; Have the gauge of above-mentioned that kind and on the opposing party's zipper strip with the configuration relatively of preceding sign indicating number, therefore, by the 2nd before during the halted state of yard part maintenance pull head; Even the strap end portion of the preceding sign indicating number side of slide fastener receives lateral pull; Also owing in the chain tooth path of navigation of pull head, contain yard part and pull head sliding-contact part before the 1st and the 2nd, thus the chain denture end separating of yard side in the past can be suppressed, and keep the engagement of chain denture.

And, in this slide fastener, can be held in the state of preceding sign indicating number from engagement of chain denture and pull head, do not make pull head slidably, make the chain denture begin separation and open slide fastener easily and promptly from frangible portion.Particularly; Under this situation; Pull head sliding-contact part on the zipper teeth chain that is configured in the opposing party is interted before the flange and the 2nd of pull head between yard part and easily deviate from, so the zipper teeth chain about can making simply separates from the deutostoma of this pull head.

In addition, disposing on the opposing party's the zipper strip under the situation of pull head sliding-contact part, pull head sliding-contact part has the sliding contacting part more than 2 that is fixed on discretely on the zipper strip, thereby can more effectively improve the horizontal intensity of drawing of slide fastener.In addition, making the chain denture when frangible portion begins to separate, can more swimmingly pull head sliding-contact part be pulled out from the deutostoma of pull head.

And; In the slide fastener of the present invention; One side's zipper strip has and is configured in the 1st analog chain tooth between yard part before chain denture and the 2nd, the opposing party's zipper strip have with and the 2nd before relative mode disposes between yard part and the 1st analog chain tooth the 2nd analog chain tooth, the 2nd analog chain tooth constitutes; About said chain denture when frangible portion begins to separate, deviate from via deutostoma from the said chain tooth path of navigation of said pull head while can push the 1st analog chain tooth.

Owing to have the 1st and the 2nd such analog chain tooth; So; Even pull head be held in preceding when sign indicating number slide fastener receive lateral pull, also can prevent that pull head sliding-contact part from deviating from from the deutostoma of pull head through the 1st analog chain tooth, thus the end separating of sign indicating number side in the past of the chain denture about suppressing.In addition; Make the chain denture when frangible portion begins to separate; The 1st analog chain tooth is pressed; So can guarantee the gap that the 2nd analog chain tooth and pull head sliding-contact part can pass through at the deutostoma of pull head, can the 2nd analog chain tooth and pull head sliding-contact part be pulled out from the chain tooth path of navigation of pull head swimmingly.

And, article coated according to the slide fastener of the present invention of the slide fastener that is sewed with structure with above-mentioned that kind, can the pull head of slide fastener be stopped by the 1st preceding yard part of preceding sign indicating number, and stably keep this halted state by the 2nd preceding yard part of preceding sign indicating number.Thus, even the slide fastener upper end that is keeping pull head is applied lateral pull, also can suppress the detaching direction slip of pull head, thereby can stably keep the engagement of chain denture to the chain denture.

Therefore; Article coated at slide fastener is under the situation of training pants of that kind of for example said patent documentation 1 record; When wearing off training pants; Receive lateral pull even be configured in the leading section of slide fastener of the waist portions of this training pants, also can stably keep the halted state of pull head, thereby keep the form of trousers.

The extension 13b of yard part 13 forms with fixed part 13a and has identical gauge before the 2nd.In addition, at the middle body of this extension 13b, be provided with the 13d of hole portion that connects at fore-and-aft direction.Because extension 13b has the 13d of hole portion, thereby can make extension 13b strain and on bandwidth direction, shrink at least.

And the outer peripheral face of this extension 13b has the 1st side wall surface 13e, the 2nd side wall surface 13f and the 3rd side wall surface 13g at least.The 1st side wall surface 13e of extension 13b, with the 1st before yard part 12 relatively dispose, and dispose at grade with the front end face of fixed part 13a.

The 2nd side wall surface 13f of extension 13b disposes from the 1st side wall surface 13e continuously, and bloats the formation of smooth curved ground laterally.Owing on extension 13b, dispose the 2nd side wall surface 13f; Thereby it is of the back; Yard part 13 has been when the back oral-lateral of pull head 20 mobile and extension 13b chain tooth path of navigation 28 in has recovered elasticity before the 2nd, and the deutostoma side end 25a that can make the guide post 25 of pull head 20 is connected to the 2nd side wall surface 13f and keeps the halted state of pull head 20.

Have again; Because the 2nd side wall surface 13f forms agley; So; State for example being connected to the 2nd side wall surface 13f from the deutostoma side end 25a of the guide post 25 of pull head 20 makes pull head 20 when the detaching direction (rear) of chain denture 3 slides; Can be while guide post 25 sliding-contacts that make the 2nd side wall surface 13f and pull head 20 so that yard part 13 promotes the strain of extension 13b in the mode that bandwidth direction shrinks before the 2nd, thereby help that yard part 13 gets between the guide post 25 and flange 26 of pull heads 20 before the 2nd.

The 3rd side wall surface 13g of extension 13b; Form continuously from the 2nd side wall surface 13f; And be configured to; The size of yard part 13 on bandwidth direction before the 2nd (that is the size of the bandwidth direction till the side edge part from the sliding-contact edge 13c of portion of fixed part 13a to the extension 13b relative with the zipper teeth chain in left side 1) reduces towards the rear gradually.

Through dispose the 3rd side wall surface 13g at extension 13b; Said when yard part 13 is in the shoulder mouth of pull head 20 entering chain tooth path of navigation 28 the 2nd before like the back; Can make guide post 25 sliding-contacts of the 3rd side wall surface 13g and pull head 20 on one side; Yard part 13 gets in the chain tooth path of navigation 28 swimmingly before making on one side the 2nd, and can promote the strain of extension 13b and make that yard part 13 shrinks before the 2nd on bandwidth direction.

In this embodiment; Full-size before the 2nd on the bandwidth direction of yard part 13, promptly, the full-size on the bandwidth direction from the sliding-contact edge 13c of portion of fixed part 13a to zipper teeth chain extension 13b and the left side till the 1 relative opposite side edges portion (the left side side edge part of extension 13b) is set at, and is bigger than guide post 25 in the chain tooth path of navigation 28 of pull head 20 and the interspersed width between the flange 26.

At this, the guide post 25 and the interspersed width between the flange 26 of so-called pull head 20 are the intervals between guide post 25 and the flange 26, are meant distance air line distance the most in short-term link from the sidewall of guide post 25 to the situation of the internal face of flange 26 with straight line under especially.

In the zipper teeth chain 1 on right side, between preceding sign indicating number 11 and chain denture 3, dispose the 1st analog chain tooth 17.Particularly, in this embodiment, yard part 12 and when stopping before the 1st of sign indicating number 11 the before pull head 20 is connected to, the 1st analog chain tooth 17 are disposed at the position of the part of deutostoma that can shutoff pull head 20.In addition, the 1st analog chain tooth 17 has: be fixed in the main part 17a on the zipper strip 2; From the head 17b of main part 17a to the extension of band foreign side.

Under this situation, the head 17b of the 1st analog chain tooth 17 have can with the zipper teeth chain 1 that is configured in the left side on after the sliding contact surface of the 2nd analog chain tooth 18 sliding-contacts stated.In addition, this head 17b, through the excision of the part of its rear side is formed, and constitute not can with slide fastener coupling element 4 engagements of the front end of the chain denture 3 that is configured in the left side.

The pull head sliding-contact part 14 of zipper teeth chain 1 that is configured in the left side of this embodiment installing with preceding sign indicating number 11 relative modes, and has: the 1st sliding contacting part 15 that is configured in front side; With the 2nd sliding contacting part 16 that is configured in rear side.These the 1st and the 2nd sliding contacting parts 15,16 will on zipper strip 2, form with the synthetic resin injection moulding of slide fastener coupling element 4 identical materials, thereby form are fixed on the zipper strip 2 to be separated from each other independently.

In addition, the 1st and the 2nd sliding contacting part 15,16 forms with the mode that when face side is observed, has essentially rectangular respectively, and in addition, the 1st sliding contacting part 15 forms longlyer than the 2nd sliding contacting part 16 on the strip length direction.Under this situation; Gauge on the above-below direction of the 1st and the 2nd sliding contacting part 15,16 is set for; Than extend from the upper flange of pull head 20 23 flange 26 that is provided with extend from lower wing plate 24 band that forms between the flange 26 that is provided with intert groove groove at interval greatly, and littler than the interval between the inner surface of the upper and lower wing plate 23,24 of pull head 20.

Thus, the 1st and the 2nd sliding contacting part 15,16 is interspersed in the chain tooth path of navigation 28 of pull head 20 swimmingly.In addition; When the 1st and the 2nd sliding contacting part 15,16 is housed in the chain tooth path of navigation 28 of pull head 20; Even slide fastener 10 receives lateral pull; The the 1st and the 2nd sliding contacting part 15,16 also can not break away from from the interspersed groove of the band of pull head 20, but is connected to the flange 26 of this pull head 20, so can the 1st and the 2nd sliding contacting part 15,16 stably be remained in the chain tooth path of navigation 28.

In addition; In this embodiment; Width dimensions on the bandwidth direction of the 1st and the 2nd sliding contacting part 15,16 though be set at more than the size of regulation in order to improve with the constant intensity of zipper strip 2, is set forr a short time than the guide post 25 and the interspersed width between the flange 26 of pull head 20.

Particularly; Width dimensions on the bandwidth direction of the 1st and the 2nd sliding contacting part 15,16 is set following size for: be held under the situation (with reference to Fig. 4) of yard part 13 before the 2nd like the said pull head 20 in back, can interting formed gap between the flange 26 in before the 2nd left side of yard part 13 and pull head 20.Thus; For example the chain denture 3 about making is when frangible portion 6 begins to separate; Can make the gap of the 1st and the 2nd sliding contacting part 15,16, thereby easily the 1st and the 2nd sliding contacting part 15,16 pulled out from the deutostoma of pull head 20 through formation between the flange 26 in the left side of yard part 13 the 2nd before and pull head 20.

In the zipper teeth chain 1 in left side, between pull head sliding-contact part 14 (the 1st and the 2nd sliding contacting part 15,16) and chain denture 3, dispose the 2nd analog chain tooth 18.The 2nd analog chain tooth 18 has: be fixed in the main part 18a on the zipper strip 2; With the head 18b that extends to band foreign side from main part 18a, the header arrangement of the 2nd analog chain tooth 18 have can with the sliding contact surface of the 1st analog chain tooth 17 sliding-contacts on the zipper teeth chain that is configured in the right side 1.

In this embodiment; The the 1st and the 2nd analog chain tooth 17,18; About chain denture 3 be in engagement and pull head 20 and be held under the situation of preceding sign indicating number 11; Through making the head 17b of the 1st and the 2nd analog chain tooth 17,18,18b contacts with each other, and can prevent that pull head sliding-contact part 14 and the 2nd analog chain tooth 18 from deviating from from the deutostoma of pull head 20.

On the other hand; Under the situation that has begun to separate from frangible portion 6 like the chain denture 3 of back about said making; Owing to dispose the 1st and the 2nd analog chain tooth 17,18; The 2nd analog chain tooth 18 can be pushed the 1st analog chain tooth 17 and make its rotation, thereby the pull head sliding-contact part 14 on the zipper teeth chain 1 that is configured in the left side is pulled out (with reference to Fig. 6～Fig. 8) from the deutostoma of pull head 20.

Then; In the slide fastener 10 of this embodiment of the structure with above-mentioned that kind; About from about the state that separates of chain denture 3, make pull head 20 slide and the action of this pull head 20 when preceding sign indicating number 11 stops and keeping described to the engagement direction (top) of chain denture 3.

At first, pull head 20 is slided to the engagement direction of chain denture 3, the chain denture 3 about making gets into chain tooth path of navigation 28 from the shoulder mouth of pull head 20, thus alternately engagement successively of the slide fastener coupling element about making 4.

If pull head 20 is slided; Then about chain denture 3 after; The 2nd analog chain tooth 18 that is configured on the 1st analog chain tooth 17 and the zipper teeth chain 1 that is configured in the left side on the zipper teeth chain 1 on right side gets in the chain tooth path of navigation 28 from the shoulder mouth of pull head 20; Afterwards; Then the 1st and the 2nd analog chain tooth 17,18 is as shown in Figure 2, is configured in the 2nd sliding contacting part 16 on yard part 13 and the zipper teeth chain 1 that is configured in the left side before the 2nd on the zipper teeth chain 1 on right side and gets in the chain tooth path of navigation 28 from the shoulder mouth of pull head 20.

Then; If before the 2nd yard part 13 and the 2nd sliding contacting part 16 relatively in chain tooth path of navigation 28 towards the deutostoma side shifting; Then as shown in Figure 3; Before the 2nd the sliding-contact edge 13c of portion of yard part 13 be configured in flange 26 sliding-contacts on the right side of pull head 20, and be disposed at the 3rd side wall surface 13g of the extension 13b of yard part 13 before the 2nd and guide post 25 sliding-contacts of pull head 20.

At this moment; Full-size before the 2nd on the bandwidth direction of yard part 13; Though as previously mentioned; Set greatlyyer than guide post 25 in the chain tooth path of navigation 28 of pull head 20 and the interspersed width between the flange 26, width dimensions reduces but the extension 13b of the 2nd preceding yard part 13 carries out strain, thereby yard part 13 interts between guide post 25 and flange 26 before can making the 2nd.

Particularly; In this embodiment; Because the 3rd side wall surface 13g before the 2nd among the extension 13b of yard part 13 is so that the mode tilted configuration that the width dimensions of yard part 13 reduces towards the rear gradually before the 2nd; So through making guide post 25 sliding-contacts of the 3rd side wall surface 13g and pull head 20; Can promote the strain of extension 13b on one side,, can intert under the situation that is not hooked in guide post 25 between guide post 25 and flange 26 Yi Bian yard part 13 gets in the chain tooth path of navigation 28 swimmingly before making the 2nd.

On the other hand; About the 2nd sliding contacting part 16 in the zipper teeth chain 1 in left side; As previously mentioned; The gauge of the 2nd sliding contacting part 16 is set forr a short time than the interval between the inner surface of the upper and lower wing plate 23,24 of pull head 20, and its width dimensions is set forr a short time than the guide post 25 and the interspersed width between the flange 26 of pull head 20.Therefore, can after the 2nd analog chain tooth 18, the 2nd sliding contacting part 16 be got in the chain tooth path of navigation 28 swimmingly.

And; When through make pull head 20 further to the top slide make yard part 13 the 2nd before extension 13b on one side strain one side when the back oral-lateral of pull head 20 relatively moves; Then the 2nd preceding yard part 13 and the 2nd sliding contacting part 16, the 1 preceding yard parts 12 and the 1st sliding contacting part 15 get in the chain tooth path of navigation 28 from the shoulder mouth of pull head 20.

Then, as shown in Figure 4, the 12b of fastening portion on yard part 12 is connected to the right side flange 26 of pull head 20 before the 1st owing to be configured in, so the slip of pull head 20 is stopped.In addition; With the 1st before the 12b of fastening portion of yard part 12 when being connected to the right side flange 26 of pull head 20; Perhaps the 12b of fastening portion of yard part 12 is about to be connected to before the right side flange 26 of pull head 20 before the 1st; Size the best part before the 2nd on the bandwidth direction of yard part 13 compares with the deutostoma side end 25a of the guide post 25 of pull head 20 and to move to the rear, thereby the extension 13b of yard part 13 recovers elasticity before the 2nd.

Thus; Can make the deutostoma side end 25a of the guide post 25 of pull head 20 be connected to the 2nd side wall surface 13f of extension 13b; So can support the pull head 20 that stops because of the 1st preceding yard part 12 reliably through the 2nd preceding yard part 13, thereby stably keep the halted state of pull head 20.

Particularly; Under this situation; In the slide fastener 10 of this embodiment; Make yard part 13 before the 2nd be connected to the deutostoma side end 25a of the guide post 25 of pull head 20 owing to being accompanied by the elastic return of yard part 13 before the 2nd,, can bring variation to the operation feeling of pull head 20, can produce little contact sound so yard part 13 is connected to moment of the deutostoma side end 25a of guide post 25 before the 2nd.

Thus, for the user of slide fastener 10, can perceive the 2nd preceding yard part 13 and be connected to the deutostoma side end 25a of guide post 25, thereby the halted state that can confirm pull head 20 is held through the 2nd preceding yard part 13.Consequently, can make the user habitually make consciously pull head 20 slide into the 1st before the operation of stop position of yard part 12 butts.

In addition, as shown in Figure 4, in this embodiment, when yard part 13 kept before pull head 20 is by the 2nd, the 1st and the 2nd sliding contacting part 15,16 on the zipper teeth chain 1 on the left of being configured in became the state in the chain tooth path of navigation 28 that is accommodated in pull head 20.Particularly, the 2nd sliding contacting part 16 is under the state that yard part 13 leaves a little before with respect to the 2nd, before the 2nd between the flange 26 in the left side of yard part 13 and pull head 20.

And; The 1st analog chain tooth 17 fetch bits that are configured on the zipper teeth chain 1 on right side become; Under the 2nd analog chain tooth 18 on the head that makes the 1st analog chain tooth 17 and the zipper teeth chain 1 that is configured in the left side and slide fastener coupling element 4 state of contact (perhaps approaching state) adjacent, with a part of locking of the deutostoma of pull head 20 with the 2nd analog chain tooth 18.

Make pull head 20 stop and keeping like this at preceding yard 11; Since be connected to pull head 20 guide post 25 deutostoma side end 25a the 2nd before the size of bandwidth direction of yard part 13; Interspersed width than between guide post 25 and the flange 26 is big, so can stably keep the halted state of pull head 20.

In addition; Be held under the state of preceding sign indicating number 11 at pull head 20; Even the leading section that disposes preceding sign indicating number 11 to for example slide fastener 10 applies the lateral pull that pulls on zipper strip 2 detaching directions about the edge makes; In the chain tooth path of navigation 28 of pull head 20; Before sign indicating number 11 (the 1st and the 2nd before yard parts 12,13) still stably be held with pull head sliding-contact part 14 (the 1st and the 2nd sliding contacting part 15,16), and the 1st and the 2nd analog chain tooth 17,18 is held making under each other head 17b, the 18b state of contact.Therefore, the zipper teeth chain 1 about can preventing is deviate from pull head 20, prevent to be in engagement about chain denture 3 separate.

In addition; Applied at leading section under the situation of lateral pull slide fastener 10; Since about the stress of the direction that is separated from each other from pull head sliding-contact part 14 and preceding sign indicating number 11 of flange 26, so 20 effects make this pull head 20 to the detaching direction (rear) of chain denture 3 such power of sliding to pull head.But the pull head 20 of this embodiment is stably kept through the 2nd preceding yard part 13 as stated, slides to the detaching direction of chain denture 3 so can prevent pull head 20 effectively.

Then, about being held state (with reference to Fig. 4) in preceding sign indicating number 11 from pull head 20, describe the action of pull head 20 when the detaching direction of chain denture 3 is the rear slide.

Under this situation, climb 22 in drawing of the pull head 20 of preceding sign indicating number 11 pull head 20 rearward pulled through gripping to be held, with the 2nd preceding yard part 13 of the deutostoma side end 25a butt of the guide post 25 of pull head 20, relatively the shoulder oral-lateral towards pull head 20 moves.At this moment, the guide post 25 of pull head 20 is on one side the extension 13b that can push yard part 13 before the 2nd so that this extension 13b strain, makes the 2nd preceding yard part 13 intert between the flange 26 on the guide post 25 of pull head 20 and right side on one side.

Particularly, in this embodiment, the 2nd side wall surface 13f of extension 13b forms agley.Therefore; When the state that is connected to the 2nd side wall surface 13f of yard part 13 before the 2nd at the deutostoma side end 25a from guide post 25 slides pull head 20; Through utilizing the curved surface of the 2nd side wall surface 13f; Can be on one side promote the strain of extension 13b through the 2nd side wall surface 13f, make the 2nd on one side before yard part 13 get between guide posts 25 and the flange 26, so the big situation of mitigation resistance to sliding change can begin at the slide of pull head 20 time.

And; Get between guide post 25 and the flange 26 through yard part before making the 2nd like this 13; Can remove pull head 20 through the 2nd preceding yard part 13 maintained states; So pull head 20 is rearward slided swimmingly, and the operation through this pull head 20 is rearward slided, the chain denture 3 about can making is separated.

Then, about in the slide fastener 10 of this embodiment, from about chain denture 3 engagement and pull head 20 be held in the state of preceding sign indicating number 11, be the action of starting point when chain denture 3 is separated successively with the frangible portion 6 of being located at chain denture 3, describe.

Under this situation; Through the frangible portion 6 of being located at chain denture 3 is applied for example lateral pull iso-stress, the chain denture 3 about can making through this frangible portion 6 is separated, and then; Through with about zipper teeth chain 1 pull to the direction that is separated from each other; Of Fig. 5, before can keeping pull head 20 remained in sign indicating number 11 state unchangeably, the slide fastener coupling element 4 about making separates successively till the leading section and rearward end of chain denture 3.

Then; After slide fastener coupling element 4 engagement each other of the front end of the chain denture 3 about being disposed at is disengaged; Through the further zipper teeth chain 1 that pulls the left side, make that the 2nd analog chain tooth 18 on the zipper teeth chain 1 that is configured in the left side is pushed the 1st analog chain tooth 17 on the zipper teeth chain 1 that is configured in the right side.

At this moment; As shown in Figure 6; Because the 1st analog chain tooth 17 and the 2nd analog chain tooth 18 are not meshing with each other, so the 1st analog chain tooth 17 receives pressing force and main looking when observing to rotation counterclockwise, thus from the 2nd analog chain tooth 18; Deutostoma by the pull head 20 of the 1st analog chain tooth 17 shutoff is opened, Yi Bian and the 2nd analog chain tooth 18 easily pull out with 17 sliding-contacts of the 1st analog chain tooth on one side from the deutostoma of this pull head of opening 20.

And, after pull head 20 is deviate from, pull the zipper teeth chain 1 in left side at the 2nd analog chain tooth 18; Thus; The 1st sliding contacting part 15, after the 2nd analog chain tooth 18, with 1st analog chain tooth 17 contact on one side from the deutostoma of pull head 20 deviate from one side; After the 1st sliding contacting part 15, the 2nd sliding contacting part 16 contacts with the 1st analog chain tooth 17 on one side to deviate from from the deutostoma of pull head 20 on one side in addition.

Particularly; In this embodiment; Pull head sliding-contact part 14 is cut apart and is formed the 1st sliding contacting part 15 and the 2nd sliding contacting part 16; So can interting, before the flange 26 and the 2nd in the left side of pull head 20, between yard part 13, deviates from swimmingly the 1st and the 2nd sliding contacting part 15,16 from the deutostoma of pull head 20.Thus, the zipper teeth chain 1 about can drawing back and slide fastener 10 is opened fully.

Like this; Slide fastener 10 according to this embodiment; Owing to being held under the state of preceding sign indicating number 11 frangible portion 6 of being located at chain denture 3 is applied lateral pull at pull head 20; So, can be under the situation of slide pull head 20 not, the chain denture 3 about making begins to separate and open slide fastener 10 from this frangible portion 6 easily and promptly.

In addition, more than the slide fastener 10 of the embodiment of explanation constitutes, and is provided with frangible portion 6 in chain denture 3, and the chain denture 3 about can making begins to separate from this frangible portion 6.But the present invention as previously mentioned, is also included within the slide fastener that the chain denture is not provided with frangible portion.

Therefore, for example the variation shown in Fig. 9 is such, and under the situation of the slide fastener 10 ' that frangible portion is not set on the chain denture 3 ', the chain denture 3 about under the situation that does not have slide pull head 20 can not separated.Therefore; In this slide fastener 10 '; Can omit in the above-described embodiment for pull head sliding-contact part 14 is pulled out and the 1st and the 2nd analog chain tooth 17,18 that is provided with from pull head 20, and replace these the 1st and the 2nd analog chain teeth 17,18 and common slide fastener coupling element 4 is installed.

And in the present invention, the shape about the 1st and the 2nd preceding yard part 12,13 and/or pull head sliding-contact part 14 also is not limited to above-mentioned embodiment, can at random change as required.

Promptly; Yard part before the of the present invention the 1st; As long as can be connected at least 1 shoulder oral-lateral end in the guide post 25 of pull head 20, upper and lower wing plate 23,24 and the flange 26 slip of pull head 20 is stopped; The 12b of fastening portion of preceding yard part 12 that kind of the 1st in the above-mentioned embodiment then also can be set, also can adopt for example the 1st preceding yard part 12 ' of that kind shown in Figure 9.

About this 1st preceding yard part 12 ' shown in Figure 9; The size of the bandwidth direction of yard part 12 ' is set greatlyyer than guide post 25 in the chain tooth path of navigation 28 of pull head 20 and the interspersed width between the flange 26 before the 1st; The shoulder oral-lateral end of the guide post 25 through being connected to pull head 20 and the shoulder oral-lateral end of flange 26 can make the slip of pull head 20 stop.

In addition; As long as yard part is before the of the present invention the 2nd: the full-size of the bandwidth direction of the sliding-contact edge portion of yard part till the opposite side edges portion is set greatlyyer than guide post 25 the chain tooth path of navigation 28 of pull head 20 and the interspersed width the flange 26 before the 2nd; And can so that before the 2nd at least a portion of yard part to the mode strain that bandwidth direction shrinks, just can adopt that kind shown in Figure 9 for example the 2nd before the variety of way of that kind shown in (a)～(j) of mode or Figure 10 of yard part 13 '.

And, about making the means of yard part 13 strains before the 2nd, be not limited to above-mentioned that kind and before the 2nd, form the 13d of hole portion that connects band table back of the body direction on yard part 13.For example use elasticity excellent synthetic resin and/or elastomer as the material of yard part 13 before the 2nd, also can make the 2nd before yard part 13 can constitute on strain ground.

In addition; In the above-mentioned embodiment, the pull head sliding-contact part 14 on the zipper teeth chain 1 on the left of being configured in is made up of 2 sliding contacting parts 15,16 that are fixed in discretely on the zipper strip 2; But among the present invention; Also can constitute pull head sliding-contact part 14, perhaps, also can that kind as shown in Figure 9 be unitarily formed pull head sliding-contact part 14 ' by the sliding contacting part more than 3.

Then, article coated about the slide fastener of the slide fastener of the present invention 10 that is sewed with above-mentioned that kind for the situation of training pants 30, describe.In addition, make the article coated training pants that is not limited to of slide fastener of slide fastener 10 of the present invention, also can be applied to other extensive stocks.

At this, Figure 11 is the stereogram of this training pants of expression, and Figure 12 is with the partial enlarged drawing shown in the amplification of the frangible portion on the chain denture that is formed on slide fastener.Figure 13 is the enlarged drawing shown in the leading section of the slide fastener on the waist portions that is configured in this training pants is amplified, and to be explanation make the key diagram of the relation of the sewing line that forms in training pants and slide fastener with slide fastener to Figure 14.

Training pants 30 shown in Figure 11 uses the excellent material of retractility to process.This training pants 30, from about the end of waist side of two shanks 31 in the scope of the other end of bottom of s trouser leg side, be sewed with slide fastener 10, and constitute, through opening slide fastener 10, can training pants 30 be opened into sheet portion of predecessor and back body sheet portion.In addition, making on the chain denture 3 of the slide fastener on this training pants 30 10, the weak frangible portion 6 of engagement force is arranged near the knee.

And; In this training pants 30; The zipper strip 2 of each slide fastener 10 is made through sewing machine under the state of the end edge portion that coincides with training pants 30, so in the left and right sides that clips chain denture 3, be formed with slide fastener 10 is made the sewing line (stitch) 32 that on training pants 30, forms.Under this situation, be configured in the sewing line 32 of the left and right sides of chain denture 3, only make the 32a of portion and form through the parallel with chain denture 3 the 1st.

In existing slide fastener article coated (for example training pants), want to be formed at the sewing line of the left and right sides of chain denture under the situation of sewing zipper, parallel with chain denture 3 and spread all over slide fastener and integrally form.Before for example on slide fastener, disposing under sign indicating number and the situation of graftings-separate pieces, about sewing line, on the strip length direction of zipper strip from than preceding sign indicating number position on the front to than of the position formation of grafting-separate pieces by the rear.

Relative with it, in the training pants 30 of this embodiment, as Figure 13 and shown in Figure 14, the side (being the sewing line 32 on right side) in the sewing line 32 that the left and right sides and the chain denture 3 of chain denture 3 forms does not abreast spread all over slide fastener 10 and integrally forms.

Promptly; The front position 32b of preceding sign indicating number 11 sides in the sewing line 32 on right side (the 1st makes the 32a of portion); On the strip length direction; The position 33a of deutostoma side end 25a that is held the guide post 25 of this pull head 20 under the situation of preceding sign indicating number 11 with pull head 20 compares by rear side (disposing a side of graftings-separate pieces) setting, preferably, compares by rear side with the position 33b of the center line of the strip length direction of the 2nd analog chain tooth 18 and to set.

In other words; Under the situation of the training pants 30 of this embodiment; The sewing line 32 on right side; At least be held with pull head 20 and compare not on the front in the position 33a of the deutostoma side end 25a of the guide post 25 of this pull head 20 of 11 o'clock of preceding sign indicating number that side forms, the sewing line 32 on right side is compared on the strip length direction shorter with the sewing line 32 in left side.

Set owing to like this front position 32b of the sewing line 32 on right side is compared with the position 33a of the deutostoma side end 25a of guide post 25 to set and then compare by rear side with the position 33b of the center line of the 2nd analog chain tooth 18 by rear side; So; For example when the waist of training pants 30 is made the leading section of slide fastener 10 receive lateral pull by pulling, leave at the position of bearing lateral pull that can make slide fastener 10 rearward lateral deviation.

That is, under the situation of written or printed documents embodiment, the part that can make lateral pull be difficult to act on not form sewing line 32 (that is, comparing the part of side on the front) with the position 33a of the deutostoma side end 25a of the guide post 25 of pull head 20.

Consequently, in the part that disposes the sewing line 32 parallel with chain denture 3, about chain denture 3 mesh securely, so also can bear even receive lateral pull.On the other hand, at the leading section of the slide fastener that maintains pull head 20 10, owing to do not form sewing line 32, so can reduce the lateral pull that this leading section receives.

Thus and since can also reduce via about chain denture 3 act on the stress of pull head 20, be held in the state of preceding sign indicating number 11 so can stably keep pull head 20.Therefore, according to the training pants 30 of this embodiment,, can prevent effectively that also pull head 20 from sliding to the detaching direction of chain denture 3 even be held the powerful waist that pulls training pants 30 under the state of preceding sign indicating number 11 at pull head 20.

And, owing to dispose such cover body 34, so, be held from pull head 20 when the state of preceding sign indicating number 11 rearward slides pull head 20, can cover body 34 be used as the handle that the user grips slide fastener 10.Therefore, pull head 20 is rearward slided, can improve the operability of slide fastener 10.

As stated; The training pants 30 of this embodiment; Pull head 20 through making slide fastener 10 slides and chain denture 3 is separated, the zipper teeth chain 1 about can drawing back and training pants 30 is opened into sheet portion of predecessor and back body sheet portion from the form of trousers, in addition; Zipper teeth chain 1 through about chain denture 3 being engaged with each other link can make training pants 30 return to the form of trousers.

In addition, though for example when wearing off training pants 30 waist of training pants 30 pulled, also can make lateral pull be difficult to act on the leading section that does not form sewing line 32 on the right side of slide fastener 10.And, the slide fastener 10 of this embodiment, can through preceding sign indicating number 11 the 2nd before yard part 13 stably keep the halted state of pull head 20.Therefore,, also can not rely on staff ground and suppress pull head 20 and at random slide, can stably keep the engagement of chain denture 3 to the detaching direction of chain denture 3 even lateral pull acts on the leading section of slide fastener 10 when wearing off training pants 30.

Therefore; The training pants 30 of this embodiment; Even when wearing when taking off the powerful waist that pulls; Also can stably keep the form of trousers, and not have the situation that pull head 20 slides with respect to chain denture 3 unreasonably, so slide fastener coupling element 4 can not take place yet by the deutostoma of pull head 20 this unfavorable condition of pruning.

And; The training pants 30 of this embodiment; Because near the chain denture 3 the knee is provided with frangible portion 6, so through these frangible portion 6 parts are applied lateral pull, the chain denture 3 about just can making is separated and zipper teeth chain 1 about drawing back as previously mentioned.Thus, even under state with footwear etc. is for example raced in dress, compare with the situation of the zipper teeth chain about drawing back 1 with slide pull head 20, also can be simply and promptly slough training pants 30.

In addition, in this embodiment, the front position of the sewing line 32 on right side; Be held to compare by rear side with pull head 20 and set, preferably, compare by rear side with the position 33b of the center line of the 2nd analog chain tooth 18 and to set in the position 33a of the deutostoma side end 25a of the guide post 25 of this pull head 20 of 11 o'clock of preceding sign indicating number; But in the present invention; Replace the sewing line 32 on right side, also can be, with the front position of the sewing line 32 in left side, or the front position of sewing line 32 that accompanies the left and right sides of chain denture 3 in the centre compare by rear side with said position 33a and set; Preferably, compare by rear side with said position 33b and set.

Particularly; Through front position, be held to compare by rear side with pull head 20 and set, preferably in the position 33a of the deutostoma side end 25a of the guide post 25 of this pull head 20 of 11 o'clock of preceding sign indicating number with the sewing line 32 of the left and right sides; Compare by rear side with the position 33b of the center line of the 2nd analog chain tooth 18 and to set; Therefore, when the waist of training pants 30 is pulled, the size of the lateral pull of the leading section that acts on slide fastener 10 is further reduced; Consequently, can more stably keep the form of trousers.

Then, the training pants about other embodiments of being sewed with slide fastener of the present invention describes.

At this, Figure 15 is the enlarged drawing shown in the leading section of the slide fastener on the waist portions that is configured in training pants is amplified, and to be explanation make the key diagram of the relation of the sewing line that on training pants, forms and slide fastener with slide fastener to Figure 16.In addition, among Figure 15, the leading section of slide fastener being made the sewing line on the right side that on training pants, forms is blocked by cover body, but for the characteristic of the training pants that is easy to judge this embodiment, the sewing line of this part that is blocked is the with dashed lines diagram also.

In the training pants 40 of these other embodiments, slide fastener 10 is made the left and right sides that the sewing line 42 that on training pants 40, forms is configured in chain denture 3.In addition, the sewing line 42 that is configured in the right side of chain denture 3 has: the 1st make the 42a of portion with chain denture 3 disposes abreast; From the 1st make the 42a of portion front position 42b make the 42a of portion with respect to the 1st and the 2nd of configuration the make the 42c of portion obliquely at a predetermined angle.
