Slide fastener

Technical field

The present invention relates to can be not by the slide of pull head make slide fastener become the state of pulling open on open the slide fastener of (top open) formula.

Background technology

In the past, the slide that was known to not carry out pull head just can make pair of right and left engaged element be listed as slide fastener under engagement at the instantaneous slide fastener that becomes released state.

The slide fastener having as lower component is for example disclosed in the real public clear 55-7135 communique of Japan (patent documentation 1): pair of right and left zipper teeth chain, forms along the relative ora terminalis configuration engaged element row of zipper strip; Pull head, pair of right and left engaged element row run through in the engaged element path of navigation that is inserted in described pull head, and described pull head is by sliding and engaged element row are switched to engagement and released state along engaged element row; Separate inlay, it is made up of distolateral intubate and a socket that is arranged on this pair of right and left zipper teeth chain; On open part, it is distolateral that its pull head of coming of making to slide for closed zipper temporarily stops at another contrary with the rear end side that this separation inlay has been installed.

In the slide fastener of recording at this patent documentation 1, engaged element row are extended to more forward more distolateral and install than opening part on a side zipper teeth chain, and the upper only code of the slip engagement for making pull head is installed in the more front of the anterior clearing end of these engaged element row.Correspondingly, open part on than the opposing party's zipper teeth chain and locate more on the front, remove the core of engaged element row and zipper strip and be formed with and be configured to slim pull head and embed and depart from edge.

In the slide fastener of recording at this patent documentation 1, using carry out the such common using method of the switching of slide fastener during along with the slip of pull head, make pull head be installed on zipper teeth chain on open part and separate between inlay and slide.Can make slide fastener become engagement or released state by this sliding action.

In addition,, in the slide fastener of recording at patent documentation 1, can also promptly not make slide fastener become the state of pulling open by the slide of pull head.When promptly do not make slide fastener become released state by the sliding action of pull head, first make pull head forward end Slideslip and exceed out part, and making pull head and the upper only code butt being arranged on a side zipper teeth chain.

Make pull head slided into on only under the state of the position of code butt, the zipper teeth chain that a side of engaged element row is installed keeps pull head.But, form than the thin thickness of zipper strip owing to having removed the pull head that engaged element is listed as and core forms embedding disengaging edge, so it can and pull out through the interspersed path of band of the formation of the ora terminalis along flange in pull head.Therefore, make pull head slided into on only under the state of the position of code butt, the power that the direction front of pair of right and left zipper teeth chain being pulled away from each other to the left and right if apply is opened, can make pull head embed and depart from the engaged element path of navigation pull-out of edge from pull head.

If pull head embeds disengaging, edge pulls out from pull head, can make the engaged element leu of the slide fastener in engagement separate.In the time that engaged element is listed as engagement each other and all separates, can make intubate extract from separate the socket of inlay.Once intubate is extracted from the socket of separation inlay, and the zipper teeth chain of left and right just becomes the state separating completely each other, will be called in this wise the slide fastener of upper open type from the situation that only code side separates.

The effect of invention

In slide fastener of the present invention, the engagement side end being listed as at the engaged element of the second zipper teeth chain disposes holding member, on the first zipper teeth chain, disposes pull-out parts in the mode relative with holding member.In addition, holding member has the location division for pull head location being remained on to its engagement slip end.Therefore, in the time that the slide by pull head not becomes rapidly slide fastener to pull open state, can prevent that the end of engagement slip end side of first and second zipper teeth chain in the case of making left and right is to expanding direction rotation pull head towards separating slip end side shifting.

In addition, pull-out parts have the horizontal butt body that draws in the end of its engaged element row side, remain under the state of engagement slip end in the pull head portion of being positioned location, the horizontal butt body that draws being configured in these pull-out parts becomes the state that has stretched into ormal weight from the flange rear end of pull head to the depths of engaged element path of navigation.Thus, for example, for slide fastener, even effect have make holding member and pull-out parts away from, the horizontal pulling force of bandwidth direction, also because the horizontal flange that draws butt body to be connected to pull head is maintained in this pull head, thereby make this slide fastener can bear the horizontal pulling force of regulation.

On the other hand, the end of the engagement slip end side of first and second zipper teeth chain of left and right is being expanded, make to pull out parts with respect to holding member in the case of in the plane of zipper strip to expand direction relatively in rotary moving, can in the engaged element path of navigation of slide fastener, make horizontally to draw butt body rotation and remove engagement, and can horizontally draw the deutostoma pull-out of butt body from engaged element path of navigation by what rotated.Particularly, in this case preferably horizontal draw butt body to have in the time that pull-out parts are in rotary moving can be on one side and the dimension width flange sliding-contact rotation on one side of pull head, in strip length direction, thus, the horizontal butt body that draws easily can be pulled out from the deutostoma of pull head.

In addition, though pull head from engagement slip end to separate slip end side a little away from, the horizontal butt body that draws of the first zipper teeth chain also can stretch into towards the depths of engaged element path of navigation from the deutostoma of pull head.So, even in the case of making to pull out parts move to the direction rotation that the end of the engagement slip end side of first and second zipper teeth chain of left and right is expanded, also the horizontal butt body that draws cannot be pulled out from deutostoma, cannot make slide fastener become the state of pulling open.

In addition, described holding member has the pull head maintaining part of the halted state that maintains this pull head for keeping pull head, in this pull head maintaining part, is formed with location division.Thus, in the time that pull head moves to engagement slip end, can carry out by location division the location of pull head, and can more stably keep pull head by pull head maintaining part.Thus, in the time that the slide by pull head not becomes rapidly slide fastener to pull open state, can more positively prevent that pull head from moving.

In addition, holding member has the location protrusion as location division, the inner surface of the upper panel in this location protrusion and pull head or the inner surface butt of lower panel, even thereby make to pull out parts with respect to holding member to expand direction rotation and move in the situation that, also pull head stably can be located and remain on engagement slip end.

In addition, holding member also has the positioning convex portion as location division, the guide post butt of this positioning convex portion and slide fastener, or there is the Embedded Division as location division, this Embedded Division embeds for the pawl that stops being configured in pull head, even thereby make to pull out parts with respect to holding member to expand direction rotation and move in the situation that, also pull head stably can be located and remain on engagement slip end.

In addition, the at least one party of pull-out parts and holding member has the protuberance of expanding, this expands protuberance and is configured in to be positioned and remains between the guide post and deutostoma of pull head of engagement slip end, and outstanding towards the relative ora terminalis of relative zipper teeth chain from the relative ora terminalis of the first zipper teeth chain or the second zipper teeth chain, thereby can alleviate the operating physical force in the time making pull head carry out common closed action to separating slip end Slideslip.

In addition, pull-out parts have the rib of expanding, and/or, holding member has the rib of expanding, what pull-out parts had expands rib in the path of navigation of the pull head sliding to engagement slip end, and along the relative ora terminalis of the first zipper teeth chain and extend integratedly with the horizontal butt body that draws, what holding member had expand rib configures along the relative ora terminalis of the engagement slip end side of the second zipper teeth chain.Thus, making to pull out parts when expanding direction rotation and move, can reduce the distortion producing on the zipper strip of the first zipper teeth chain side.Thus, can be with the less angle that expands that separately measures regulation, thus can make slide fastener easily pull open.

In this case, pull-out parts have band rib, and this is formed on rib near the slide fastener zone face of of the pull head that remains on engagement side slip end of being positioned, and this band rib draws butt body and expands rib and connect to one with horizontal.Thus, in the time that the slide by pull head not becomes rapidly slide fastener to pull open state, can easily make to pull out parts and move to expanding direction rotation, thereby can make slide fastener pull open swimmingly.

In addition, holding member has the front stop for the pull head that moves to engagement side slip end is stopped, and one end of pull head maintaining part and the link of front stop.Thus, can form holding member, and can make pull head positively stop and remaining on engagement side slip end.

Especially, the expanding rib plays a role as the relative ora terminalis for strengthening the second zipper teeth chain in pull head maintaining part, making to pull out parts when expanding direction rotation and move, can be with the less angle that expands that separately measures regulation, and can make slide fastener easily pull open.

In addition, holding member has band rib, and this is formed on rib near the slide fastener zone face of of the pull head that remains on engagement side slip end of being positioned, and by this band rib, the other end of pull head maintaining part and front stop are joined into one.Thus, in the time that the slide by pull head not becomes rapidly slide fastener to pull open state, can easily make to pull out parts and move to expanding direction rotation, and can make slide fastener pull open swimmingly.

The interspersed path 50G of this band is the gap of taking out zipper strip 11 for the outside from engaged element path of navigation 50T to pull head 50, on this zipper strip 11, be provided with and run through first and second engaged element 12,13 row that are inserted in engaged element path of navigation 50T, and the interspersed path 50G of this band is in the time that pull head 50 slides and the part of zipper strip 11 sliding-contacts.

Be provided with to draw on the top (the OS direction shown in Fig. 4 and Fig. 5) of the upper panel 52 of pull head 50 and climb supporting mass 56, this draws climbs supporting mass 56 and climbs 59 draw and climb axial region 59A and run through insertion for drawing, and this is drawn and climbs 59 and support in the mode that can freely topple over.

It is to bend to the panel beating part that side-looking is コ shape that the drawing of pull head 50 shown in Fig. 4 and Fig. 5 climbed supporting mass 56, its with surround upper panel 52 from pull head 50 outstanding end 56B (with reference to Figure 14 of explanation) shape, by bearing portion 56P (with reference to the Figure 14 in rear explanation) the axle supporting of front (FS direction).Therefore, draw and climb supporting mass 56 and make rear (RS direction) can swing at above-below direction (OS-US direction) taking bearing portion 56P as fulcrum.

Draw the rear portion (part of RS direction) of climbing supporting mass 56 to be formed with to run through be inserted in the through hole being opened on upper panel 52 in and can be towards the engaged element path of navigation 50T advance and retreat of pull head 50 stop pawl 54.Under the state shown in Fig. 5, draw and climb supporting mass 56 and suppress mechanism by not shown leaf spring, helical spring etc., become and stop pawl 54 state that (US direction) suppresses by downwards.And the pawl 54 that stops having declined is embedded in the Embedded Division 94H being opened on holding member 90.In addition, in the state shown in this Fig. 5, pull head 50 is present on the position engaging with front stop 91, is embedded into and in Embedded Division 94H, pull head 50 is positioned to remain on engagement slip end by making to stop pawl 54.

As shown in Figure 3, the rear portion of guide post 50D (RS direction) is formed as sharp wedge shape.Thus, can pass through rearward (RS direction) slip of pull head 50, make to import to that the first engaged element 12 in engagement in engaged element path of navigation 50T is listed as and the second engaged element 13 is listed as direction (L-R direction) to the left and right and separates from deutostoma 50U, then discharge respectively from both sides' eyebrow mouth.

In addition, if making the front shown in pull head 50 towards Fig. 3 (FS direction) slides, the first engaged element 12 in released state and the second engaged element 13 can be imported from shoulder mouth 50S separately, thereby and by directed and converge and become first and second engaged element 12,13 row of engagement and discharge from deutostoma 50U along flange 50F.

Next, utilize Fig. 3～Fig. 5 to describe the function that is formed on the each several part on pull-out parts 80.The rib 82 that expands that is formed on relative ora terminalis side along the core 14 of the first zipper teeth chain 16 is to run through the part being inserted in engaged element path of navigation 50T under the state that pull head 50 is configured in to engagement slip end, is the part that near rigidity core 14 is improved.

Because formation expands rib 82, thereby near rigidity core 14 is improved, so, pull head 50 is being configured under the state of engagement slip end, the end of the engagement slip end side of first and second zipper teeth chain 16,17 about making in the plane of zipper strip 11 expands each other, and make to pull out parts 80 with respect to holding member 90 to expanding direction when relatively in rotary moving, can suppress the distortion of core 14.

Therefore, can obtain the angle that expands of regulation by less, first and second zipper teeth chain 16,17 separately amount each other, thereby can make the horizontal butt body 86 that draws easily from the deutostoma 50U pull-out of engaged element path of navigation 50T.So can make first and second zipper teeth chain 16,17 easily expand each other.

As shown in Figure 5, the thickness that expands the above-below direction (OS-US direction) of rib 82 is set to that to intert the gap of above-below direction (OS-US direction) of path 50G than band thin.Therefore, expand rib 82 and can intert path 50G and plugging via band with respect to overlooking the engaged element path of navigation 50T that is Y-shaped.

As shown in Figure 3, be to run through the part being inserted in engaged element path of navigation 50T under the state that pull head 50 is configured in to engagement slip end from the core 14 of the first zipper teeth chain 16 to the side-prominent protuberance 83 that expands of relative ora terminalis.Make pull head 50 from engagement slip end rearward (RS direction) slide time, expand protuberance 83 and compare and take the lead in contacting with guide post 50D with the first engaged element 12, thus the effect that performance makes the first zipper teeth chain 16 significantly expand to left (L direction).

Because making to expand protuberance 83, gives prominence to the core 14 from the first zipper teeth chain 16, so, in the time making slide fastener 50 rearward (RS direction) slides from engagement slip end, expand guide post 50D under not enough state at the first zipper teeth chain 16 and conflict with the first engaged element 12 and cause resistance to sliding increase and the unfavorable condition of operation sense deterioration thereby can reduce.

Being arranged on the horizontal end of drawing butt body 86 to be configured in the first engaged element 12 row sides of pull-out parts 80 on the relative ora terminalis in front (FS direction) in the first zipper teeth chain 16, that the first engaged element 12 is listed as, is to run through the part being inserted in engaged element path of navigation 50T under the state that pull head 50 is configured in to engagement slip end.

As shown in Figure 4, the thickness of the horizontal above-below direction (OS-US direction) that draws butt body 86 is set to thicker and thicker than expanding rib 82 than the gap of the above-below direction (OS-US direction) of the interspersed path 50G of band.Therefore, run through under the state of insertion along overlooking the engaged element path of navigation 50T that is Y-shaped at core 14, because the horizontal butt body 86 that draws is from inner side and flange 50F butt, so this horizontal butt body 86 that draws can not come off within the band of pull head 50 interts path 50G.Thus, can bear the horizontal pulling force (horizontal drag force) of the regulation in the time that direction (direction being mutually pulled away from) pulls to the left and right each other by first and second zipper teeth chain 16,17.

As shown in Figure 3, on the ora terminalis of horizontal flange 50F side of drawing butt body 86, when horizontal can be the horizontal butt range L w (with reference to the enlarged drawing of the Fig. 9 in rear explanation) that draws with the scope definition of the inwall butt of flange 50F while drawing butt body 86 mobile to left (L direction).In addition, the end of the rear of flange 50F (RS direction) is defined as to flange rear end 50R.And, pull head 50 is being configured under the state of engagement slip end, be the resistance to horizontal engaging size Ls that draws by the distance definition at the position from flange rear end 50R to horizontal forefront (FS direction) of drawing butt range L w.

By this resistance to horizontal engaging size Ls that draws is received in the size range of regulation, pull head 50 is being configured under the state of engagement slip end, can engage with the second engaged element 13 foremost by the horizontal butt body 86 that draws, or from inner side and flange 50F butt and bear the horizontal pulling force of regulation.

In addition, as utilized in the back, Fig. 8 and Fig. 9 describe, make left and right first and second zipper teeth chain 16,17 engagement slip end side each other in the plane of zipper strip 11 to expanding direction rotation, the horizontal butt body 86 that draws rotates in the engaged element path of navigation 50T of pull head 50, thereby can remove and the engaging of the second engaged element 13, and can draw the deutostoma 50U pull-out of butt body 86 from engaged element path of navigation 50T by horizontal.

In addition, about resistance to horizontal size range of drawing engaging size Ls, in the case of the installing space of first and second engaged element 12,13 is defined as P, preferably the resistance to horizontal engaging size Ls that draws is set in the scope of P/6≤Ls≤5P/6.Installing space P refers to the predetermined distance that is arranged on the engaged element on same zipper strip 11, and size that for example can be between the fore-and-aft direction of engaged element 12,13 (FS-RS direction) middle position and the same position of the engaged element 12,13 adjacent with this engaged element 12,13 is as installing space P.

In this case, when resistance to horizontal drawing in the situation that engaging size Ls is less than P/6, resistance to horizontal pulling force is low, probably causes slide fastener 10 arbitrarily to separate.On the other hand, when the resistance to horizontal engaging size Ls that draws exceedes in the situation of 5P/6, even if make the engagement slip end side of first and second zipper teeth chain 16,17 of the left and right in slide fastener 10 fronts (FS direction) each other to expanding direction rotation, also probably cause the horizontal butt body 86 that draws to be difficult to the deutostoma 50U pull-out from engaged element path of navigation 50T.

On the first zipper teeth chain 16, draw butt body 86 to be connected and to link all-in-one-piece connection reinforcement portion 85 be for expanding rib 82 and the horizontal butt body 86 that draws is arranged on the strengthening part on zipper strip 11 more firmly with expanding rib 82 horizontal.In addition, by form connection reinforcement portion 85 on the first zipper teeth chain 16, pull head 50 is being configured under the state of engagement slip end, making the end of engagement slip end side of first and second zipper teeth chain 16,17 of left and right each other when expanding direction rotation, can suppress the distortion of zipper strip 11, therefore, can obtain the angle that expands of regulation by separately amount less, first and second zipper teeth chain 16,17, thereby can make the horizontal butt body 86 that draws easily pull out from the deutostoma 50U of engaged element path of navigation 50T.

In addition, (connection reinforcement portion 85 has accordingly with the position of passing through with the hands-off mode of flange 50F and the flange 50F of pull head 50, the lower side at the position of passing through at flange 50F) than the interspersed thin part of path 50G of band, in addition, for the intensity and the rigidity that make this part improve, the thickness of the part (side, left and right (L-R direction) of pull head 50) that the flange 50F of pull head 50 can not pass through is above it increased, thereby make this part ratio expand rib 82 thick (with reference to Fig. 4 and Fig. 5).In addition, the thickness of part in connection reinforcement portion 85, that flange 50F does not pass through is set thinlyyer than the horizontal butt body 86 that draws.

Horizontal relative ora terminalis side of drawing butt body 86 be formed with towards rear (RS direction) extend into hook-shaped, for the end of engagement 87 of the engagement head engagement of relative the second engaged element 13.By forming end of engagement 87 on butt body 86 horizontal drawing, making first and second zipper teeth chain 16,17 of left and right each other when expanding direction rotation, thereby end of engagement 87 moves the rotation that promotes to expand direction along the surrounding of the engagement head of the second relative engaged element 13, therefore, can obtain the angle that expands of regulation, thereby can make the horizontal butt body 86 that draws easily pull out from the deutostoma 50U of engaged element path of navigation 50T by less, first and second zipper teeth chain 16,17 separately amount each other.

Next, utilize Fig. 3～Fig. 5 to describe the function that is formed on the each parts on holding member 90.The front stop 91 that is configured in the more front (FS direction) of the anterior clearing end that the second engaged element 13 on the second zipper teeth chain 17 is listed as is the positions by making pull head 50 engage slip end and stop with a part of butt of pull head 50.In the embodiment shown in fig. 3, because the outside dimension of the above-below direction of front stop 91 (OS-US direction) is set thicklyer than the inside dimension of the above-below direction of engaged element path of navigation 50T (OS-US direction), so become that front stop 91 can not enter in engaged element path of navigation 50T but the state that engaged.

In addition, can also with other structure replace as shown in Figure 3, front stop 91 is set than the thick embodiment of inside dimension of engaged element path of navigation 50T.For example, as shown at Figure 19 of rear explanation, can also be by front stop 491 being set to such an extent that enter in engaged element path of navigation 50T than the thin front stop 491 that makes of the inside dimension of engaged element path of navigation 50T, and by making leading section (the FS direction end) butt of the edge, rear end (RS direction end edge portion) of front stop 491 and the flange 50F of pull head 50, and can make pull head 50 stop in engagement slip end.

As shown in Figures 4 and 5, the pull head maintaining part 92 in front (FS direction) that is configured in anterior clearing end on the second zipper teeth chain 17, that the second engaged element 13 is listed as is along the opposite side edges of the second zipper teeth chain 17 and form, and the front end of this pull head maintaining part 92 and front stop 91 link.

This pull head maintaining part 92 is set to, the gap of the above-below direction (OS-US direction) of the interspersed path 50G of Thickness Ratio band of its above-below direction (OS-US direction) is thick, and thinner than the inside dimension of the above-below direction of engaged element path of navigation 50T (OS-US direction).Therefore,, in the time pull head maintaining part 92 being run through in the engaged element path of navigation 50T that is inserted in pull head 50, this pull head maintaining part 92 can remain on this pull head 50 on the second zipper teeth chain 17 and maintain the halted state of pull head 50.

In addition, pull head maintaining part 92 being run through under the state being inserted in engaged element path of navigation 50T, because the end, right side (R direction) of pull head maintaining part 92 is from inner side and flange 50F butt, so can not intert path 50G and come off from not being with.Thus, even the state having pulled out from pull head 50 at the first zipper teeth chain 16, also pull head 50 can be remained on to the second zipper teeth chain 17 sides.

Expanding protuberance 93 from the core 14 of the second zipper teeth chain 17 to side-prominent two of relative ora terminalis is to run through the part being inserted in engaged element path of navigation 50T under the state that pull head 50 is configured in to engagement slip end.Make pull head 50 from engagement slip end rearward (RS direction) slide time, expand protuberance 93 and compare and take the lead in contacting with guide post 50D with the second engaged element 13, thus the effect that performance makes the second zipper teeth chain 17 significantly expand to right-hand (R direction).

The connection front stop 91 of the second zipper teeth chain 17 is for front stop 91 and pull head maintaining part 92 are arranged on to the strengthening part on zipper strip 11 more firmly with the connection reinforcement portion 95 of the rearward end of pull head maintaining part 92.In addition, by form connection reinforcement portion 95 on the second zipper teeth chain 17, pull head 50 is being configured under the state of engagement slip end, making the end of engagement slip end side of first and second zipper teeth chain 16,17 of left and right each other when expanding direction rotation, can suppress the distortion of zipper strip 11.Therefore, can obtain the angle that expands of regulation, thereby can make the horizontal butt body 86 that draws easily pull out from the deutostoma 50U of engaged element path of navigation 50T by less, first and second zipper teeth chain 16,17 separately amount each other.

In addition, the lower side at the position that connection reinforcement portion 95 is passed through at flange 50F in the mode of not interfering with the flange 50F of pull head 50 has than band interts the thin part of path 50G, in addition, for the intensity of this part and rigidity are improved, increase (with reference to Fig. 4 and Fig. 5 compared with the part that the thickness of the part (side, left and right (L-R direction) of pull head 50) that the flange 50F of pull head 50 can not pass through is above it passed through above it with flange 50F.)。

Upper surface (face of OS direction) at the rear portion of pull head maintaining part 92 (RS direction) offers Embedded Division 94H.Pull head 50 being configured under the state of engagement slip end, be embedded in Embedded Division 94H by the pawl 54 that stops that making pull head 50 sides, pull head 50 location can be remained on to engagement slip end.For example, if the engagement slip end side of first and second zipper teeth chain 16,17 about making is each other to expanding direction rotation, along with this action expanding, pull head 50 wants rearward (RS direction) mobile.

Now, though pull head 50 rearward (RS direction) slightly move, from flange rear end 50R to horizontal distance foremost of drawing butt range L w, (the resistance to horizontal engaging size Ls that draws shown in Fig. 3) also can increase.If the resistance to horizontal engaging size Ls that draws is elongated, cannot make the horizontal deutostoma 50U pull-out of butt body 86 from engaged element path of navigation 50T of drawing.Therefore, in the embodiment shown in Fig. 1～Fig. 5, be embedded in Embedded Division 94H by the pawl 54 that stops that making pull head 50 sides, pull head 50 can be positioned to engagement slip end, thereby the resistance to horizontal engaging size Ls that draws can be received in the size range of regulation.

In addition, for pull head 50 is positioned at the structure of engagement slip end be not limited to shown in Fig. 1～Fig. 3 such, make to stop the structure that pawl 54 is embedded into Embedded Division 94H, can also use other structure.For example illustrated at rear use Figure 13 and Figure 14, can also form in such a way: from pull head maintaining part 92 along the vertical direction (OS-US direction) be formed for engaged element path of navigation 50T in upper panel 52 and/or the location protrusion 94B (location division) of lower panel 53 butts, thereby pull head 50 location is remained on to engagement slip end.

In addition, as illustrated at rear use Figure 20, side-prominent to the relative ora terminalis of first and second zipper teeth chain 16,617 with the positioning convex portion 94C (location division) of the guide post 50D butt in engaged element path of navigation 50T by making, also can make pull head 50 location remain on engagement slip end.In addition, location division be make pull head 50 move to location that engagement carries out pull head 50 when slip end with make pull head 50 can be not unexpectedly mobile parts rearward.

Because above-mentioned location division and pull head maintaining part 92 form, so in the time pulling out operation under the state that pull head 50 has been located, pull head 50 can stably be kept, and positively extracts from pull head 50 thereby can make to pull out parts 80.In addition, in order stably to keep pull head 50, pull head maintaining part 92 is preferably formed: be inserted in this pull head maintaining part 92 under the state of inside of pull head 50, the Length Ratio in strip length direction is long to the length of the end of the deutostoma 50U side of guide post 50D from the shoulder mouth 50S of pull head 50.

Next, utilize Fig. 6 and Fig. 7 to make on one side pull head 50 rearward (RS direction separates the direction of the slip end) state that makes engaged element row in engagement become released state on one side that slides describe.Fig. 6 be the state to be configured in engagement slip end from pull head 50 make pull head 50 rearward (RS direction) thus slide a little and make the vertical view cutaway drawing of the slide fastener that the state that expands a little of first and second zipper teeth chain 16,17 of left and right represents.Fig. 7 be to make from the state shown in Fig. 6 pull head further rearward (RS direction) thus the vertical view cutaway drawing of the slide fastener that the state that makes engaged element leu in engagement become released state of sliding represents.In addition also the description thereof will be omitted, the position identical with the position having illustrated in Fig. 1～Fig. 5 to be marked to identical Reference numeral.

Pull head 50 is being configured under the state of engagement slip end, if user grip draw climb 59 and rearward (RS direction) apply power, by suppress mechanism downwards (US direction) suppressed stop pawl 54 upward (OS direction) mobile.This structure is commonly referred to as the structure (with reference to Fig. 5) of the known pull head of Automatic pull head (Automatic Slider) or semi-automatic pull head (semi-Automatic Slider).If stop pawl 54 (OS direction) movement upward, stop pawl 54 and depart from from Embedded Division 94H, thereby pull head 50 become the state that can slide from the state that is positioned in engagement slip end.If user make to draw climb 59 rearward (RS direction) mobile, pull head 50 also rearward (RS direction) mobile.

As shown in Figure 6, if make rearward (RS direction) slip of pull head 50 from engagement slip end, the rearward end of the guide post 50D in pull head 50 takes the lead in and the inclined-plane butt that expands protuberance 93 of holding member 90, and the second zipper teeth chain 17 is expanded to right-hand (R direction).Then, sliding and tend to a shoulder mouthful 50S on one side at the right flank of guide post 50D on one side in the top that expands the relative ora terminalis side on protuberance 93, thus the second zipper teeth chain 17 is further expanded to right-hand (R direction).

If further make rearward (RS direction) slip of pull head 50, the rearward end of guide post 50D and the inclined-plane butt that expands protuberance 83 that pulls out parts 80, and the first zipper teeth chain 16 is expanded to left (L direction).Then, sliding and tend to a shoulder mouthful 50S on one side at the left surface of guide post 50D on one side in the top that expands the relative ora terminalis side on protuberance 83, thus the first zipper teeth chain 16 is further expanded to left (L direction).

If make pull head 50 rearward (RS direction) further slide, the inclined-plane of the engagement head of first and second engaged element 12,13 row of left and right successively with the rearward end butt of guide post 50D, thereby first and second zipper teeth chain 16,17 is in turn expanded each other.

If do not form and expand protuberance 83,93 at the relative ora terminalis of first and second zipper teeth chain 16,17, the expanding under inadequate state of first and second zipper teeth chain 16,17 of left and right, guide post 50D can with the side butt of the front of engaging head of first and second engaged element 12,13 (FS direction).So, cause the resistance to sliding of pull head 50 to increase, thereby operation sense worsened.

As described above, from deutostoma 50U, first and second engaged element 12,13 row in engagement are imported in engaged element path of navigation 50T, and utilizing guide post 50D that first and second engaged element 12,13 is listed as after direction (L-R direction) separation to the left and right, discharge respectively from both sides' shoulder mouth 50S.

Next, utilize Fig. 8～Figure 12, to pull head 50 is being configured in the mode that can not slide under the state of engagement slip end of slide fastener 10, thereby the engagement slip end side of first and second zipper teeth chain 16,17 of left and right is described each other to the action expanding in the situation that direction rotation separates slide fastener 10 rapidly.

Thereby the engagement slip end side that Fig. 8 is first and second zipper teeth chain 16,17 to make left and right from the state shown in Fig. 3 makes the horizontal vertical view cutaway drawing that draws the slide fastener 10 that butt body 86 represents from the state of the deutostoma 50U pull-out of pull head 50 to expanding direction rotation each other.Near the horizontal amplification of drawing butt body 86 shown in Fig. 8 is carried out the vertical view cutaway drawing to its explanation by Fig. 9.Figure 10 is that the X-X shown in Fig. 9 is to looking cutaway view.Figure 11 be to from the state shown in Fig. 8 and Fig. 9 further by the vertical view cutaway drawing of 16,17 points of slide fasteners that the state of opening represents 10 of first and second zipper teeth chain of left and right.Figure 12 is the top view that explanation is arranged on the separation inlay 39 of the separation slip end of slide fastener 10.In addition also the description thereof will be omitted, the position identical with the position having illustrated in Fig. 1～Fig. 5 to be marked to identical Reference numeral.

As shown in Figure 3, pull head 50 is being configured under the state of engagement slip end, even if be applied to the horizontal pulling force that pulls abreast first and second zipper teeth chain 16,17 on left and right directions, the horizontal butt body 86 that draws also can be maintained in pull head 50 from inner side and flange 50F butt, therefore can maintain first and second engaged element 12,13 row engagement each other.

And as shown in Fig. 8～Figure 10, pull head 50 is being configured under the state of engagement slip end, if the engagement slip end side of first and second zipper teeth chain 16,17 is expanded each other, and it is relatively in rotary moving to expanding direction with respect to holding member 90 to make to pull out parts 80, what form thinly than the gap of the interspersed path 50G of band expands rib 82 from being with interspersed path 50G to extract.Meanwhile, the horizontal butt body 86 that draws rotates on one side with the flange 50F sliding-contact of pull head 50 on one side, thereby this horizontal butt body 86 that draws pulls out from the deutostoma of engaged element path of navigation 50T.Now, because by horizontal engagement releasing of drawing the spinning movement of butt body 86 to make end of engagement 87 and the second engaged element 13, so can (RS direction) make the engaged element row in engagement become released state in turn towards rear afterwards.Do like this, slide fastener 10 promptly can be separated.

If the engagement releasing of whole first and second engaged element 12,13 row in slide fastener 10 and become released state, as shown in figure 12, separate the embedded body 30 of inlay 39 and be embedded into body 40 under by the state of axial region 32 axles supportings to the direction rotation that front (FS direction) is expanded.So the axial region 32 of embedded body 30 can depart from from being embedded into body 40, thereby first and second zipper teeth chain 16,17 about can making away from each other.

In addition, because become and embed the state that stops pawl 54 that has pull head 50 sides in the Embedded Division 94H of the second zipper teeth chain 17, even so apply power in the direction that the engagement slip end side of first and second zipper teeth chain 16,17 about making expands each other, also can prevent that pull head 50 is by (RS direction) moves with rearward.Thus, pull head 50 location can be remained on to engagement slip end.

In addition, as shown in Figure 9, if make the engagement slip end side of first and second zipper teeth chain 16,17 each other to expanding direction rotation, end of engagement 87 is mobile along surrounding's (side wall surface) of the engagement head of the second relative engaged element 13, thereby promotes horizontal rotation of drawing butt body 86.Thus, can be with less, first and second zipper teeth chain 16,17 angle that expands that separately measures regulation each other.

Next, utilize Figure 13 and Figure 14 to describing for other embodiment that pull head 50 location remained on to engagement slip end.Figure 13 is the vertical view cutaway drawing to form the slide fastener describing from the embodiment of the location protrusion 94B of inner and upper panel 52 and/or lower panel 53 butts in pull head maintaining part 92.Figure 14 be the X IV shown in Figure 13 to looking cutaway view, be the cutaway view that the state of the upper panel 52 in location protrusion 94B and path of navigation 50T and lower panel 53 butts is represented.In addition also the description thereof will be omitted, the position identical with the position having illustrated in Fig. 1～Fig. 5 to be marked to identical Reference numeral.

The first zipper teeth chain 16 in slide fastener 110 shown in Figure 13 and Figure 14 has and structure Fig. 1～parts illustrated in fig. 5 are identical.Front stop 91, pull head maintaining part 92 in the second zipper teeth chain 117, expand protuberance 93 and connection reinforcement portion 95 and have and structure Fig. 1～parts illustrated in fig. 5 are identical.In the embodiment shown in Figure 13 and Figure 14, replace the Embedded Division 94H shown in Fig. 1～Figure 11 and form in such a way: from pull head maintaining part 92 along the vertical direction (OS-US direction) be formed for engaged element path of navigation 50T in upper panel 52 and/or the location protrusion 94B of lower panel 53 butts, thereby pull head 50 location are remained on to engagement slip end.By such formation, also pull head 50 location can be remained on to engagement slip end, and the resistance to horizontal engaging size Ls that draws can be received in the size range of regulation.

By the resistance to horizontal engaging size Ls that draws is received in the size range of regulation, under the state that pull head 50 is configured in to engagement slip end, can bear the horizontal pulling force of regulation, and make left and right first and second zipper teeth chain 16,117 engagement slip end side each other in the plane of zipper strip 11 to expanding direction rotation, can draw the deutostoma 50U pull-out of butt body 86 from engaged element path of navigation 50T by horizontal, thereby slide fastener 110 is promptly separated.

In addition, utilize Figure 14 to illustrate and draw the swing fulcrum of climbing supporting mass 56.From the upper panel 52 of pull head 50 front portions (FS direction) be extruded with by draw climb that supporting mass 56 supports in the mode that can freely swing end 56B.Be formed with the bearing portion 56P of pivot point shape at the both ends, left and right (sidepiece of L-R direction) of playing end 56B.Draw climb supporting mass 56 taking bearing portion 56P as fulcrum with respect to rise an end 56B be supported in the mode that can freely swing, further, make to draw the pawl 54 (with reference to Fig. 5) that stops of climbing supporting mass 56 to be suppressed in the direction passing in and out in engaged element path of navigation 50T by the not shown mechanism of suppressing.
