Invention content

In above-mentioned patent 201520093267.X first it is common upper only and the second work(in patent 201610137272.5 Energy upper stop member is all provided with through-hole section on it, makes to form the elastic arm for capableing of dilatation on the inside of it by the through-hole section. Described first is common upper only very small with the volume of the second function upper stop member, it is possible thereby to it is intended that for manufacturing it Mold it is also very small, raised mold core of the processing for being molded the through-hole section is very difficult on the mold of such small size 's.It is therefore necessary to further improve the upper structure only.

In consideration of it, the present invention proposes a kind of slide fastener for having and easily taking off above only, including axially extending left zipper band, right slide fastener Band and the pull head that sprocket can be allowed to latch, are provided with upper left stop member, in the sprocket of right zipper strip in the sprocket head end of left zipper band Head end is provided with upper right stop member；Pull head includes the upper cover plate being oppositely arranged, lower cover and is connected between upper cover plate, lower cover simultaneously Positioned at drawing procephalic intermediate connecting pole, the both sides of the intermediate connecting pole be respectively provided with can allow sprocket by a left side enter channel Enter channel with the right side, the pull head rear portion have can allow sprocket by and be connected to the left side enter channel, it is right enter channel after go out Channel；It is characterized in that, the upper projecting portion that can prevent the pull head abjection is provided at the top of the upper right stop member, it is described The top end part of upper left stop member corresponds to stage casing region or the hypomere region arrangement of the upper right stop member, when the pull head is moved to institute When stating slide fastener head end position and riding up in the upper right stop member and abut against the upper projecting portion, the upper left stop member can be from institute Go out in channel to be detached from the pull head after stating pull head；The upper left stop member and the upper right stop member are plastic parts, when their left and right When spelling is close together, in the axial direction at least with one section can with it is described after go out channel formed interference fit combination wall body Section, the combination wall body section is rigid structure wall body section.

Wherein, the upper right stop member is the component of the maximum upward stroke for limiting pull head, and integral type may be used Structure can also use split structure.Further technical solution is also possible that the upper right stop member includes upper and lower point The the first upper right stop and the second upper right stop set, the second upper right stop are located at the lower section of the first upper right stop, institute It states upper projecting portion and the first upper right stop is integrally formed.

Wherein, the left side enter channel, it is right enter channel and the connection left side enter channel, it is right enter channel after to go out channel be shape Sprocket channel between upper cover plate, lower cover described in Cheng Yu, the sprocket channel are substantially in Y-type layout.The left zipper band and The sprocket of the right zipper strip enters channel by the left side and the right side enters channel and enters in the pull head and go out channel in the rear Inside converge lock together.Similarly the upper left stop member and upper right stop member are also to enter channel and the right side by the left side to enter channel and enter Go out in the pull head and in the rear in channel to converge spelling and be close together.

Wherein, the upper projecting portion is provided in the tectosome of the upper right stop member, can the relatively described upper right stop member Other regions have and bigger transverse width and extend outward so as to be stuck on the lateral wall of the pull head, and or Person can other regions of the relatively described upper right stop member have and bigger vertical height and upwardly extend so as to be stuck in It states on the upper cover plate of pull head.The upper projecting portion is for when preventing from pulling up the pull head, the pull head to cross the upper right Stop member and completely disengage the right zipper strip.

Wherein, the top end part of the upper left stop member corresponds to stage casing region or the hypomere region arrangement of the upper right stop member, Features described above defines the position relationship between the upper left stop member and the upper right stop member, and the top end part of the upper left stop member can It is arranged with the stage casing region of the correspondence upper right stop member or hypomere region, but not the epimere region cloth of the corresponding upper right stop member It sets.Such layout type so that when the pull head abuts against the upper projecting portion, the upper left stop member can be from the drawing Go out in channel to be detached from the pull head after head, so that the left zipper band can also be detached from the pull head.

Wherein, the upper left stop member and the upper right stop member are plastic parts, and the combination wall body section is rigid structure wall body Section.Features described above defines the design feature of the upper left stop member and the upper right stop member, the upper left stop member described first and described Upper right stop member is the component using plastic manufacturing, by the material characteristic of plastics to can micro flexible deformation ability； Secondly, the combination wall body section of the upper left stop member and the upper right stop member uses rigid structure, i.e., in the combination wall body section Elastic construction without elastic-like arm.The elastic construction can be general similar to first in patent 201520093267.X It is logical upper only and the both ends that side is formed within by through-hole section in the second function upper stop member in patent 201610137272.5 Fixed elastic arm；It can also be that one end is fixed, the other end is in the elastic arm of free state.In conclusion described group is combined harmoniously Body section not instead of by be arranged elastic construction, by the material physical characteristic of itself obtain can micro flexible deformation energy Power.

Wherein, when the upper left stop member and the upper right stop member or so spelling are close together, at least have in the axial direction Have one section can with it is described after go out between channel to be formed the combination wall body section of interference fit.In this way, by the combination wall body section With go out channel after the pull head interference fit clamping stagnation described in pull head, so that the pull head is located in the upper left stop member and described In upper right stop member, so as to make the sprocket of the left zipper band and right zipper strip keep lock state.When slightly firmly upward Pull the pull head make the pull head squeeze the combination wall body section bring it about micro elastic shrinkage deform to make it is described The combination wall body section can be passed through and be finally detached from the upper left stop member by going out channel after pull head.

According to above-mentioned technical proposal it can be found that compared with prior art, the beneficial technical effect of the present invention lies in：Due to The upper left stop member and the upper right stop member are plastic parts, and the combination wall body section is rigid structure wall body section.As long as rationally setting Set the upper left stop member and the upper right stop member combination wall body section and the pull head after go out fit dimension between channel i.e. It can to form interference fit between them.By the interference fit and the upper left stop member and the upper right stop member The clamping stagnation positioning of the pull head can be thus achieved in elastic deformability possessed by itself and the pull head stops with the upper left The disengaging of part.In this way, it is convenient to omit in order to improve the elastic deformability of the upper left stop member and the upper right stop member and specially In the through-hole section of setting, with patent 201520093267.X first it is common upper only and second in patent 201610137272.5 Function upper stop member is compared, and the structure of upper left stop member of the invention and the upper right stop member is simpler, significantly simplifies mold Structure.

Further technical solution be also possible that the combination wall body section on transverse width with it is described after go out channel and formed Interference fit.In specific setting, the transverse width of the combination wall body section can be than going out channel width 0.1mm to 0.2mm after described.

Detailed discussion first is done to first pull head 4 and the upper structure only below in conjunction with the accompanying drawings.

As shown in Fig. 3, Fig. 4 and Fig. 5, first pull head 4 includes the upper cover plate 41 being oppositely arranged, lower cover 42, setting It pulling-on piece 47 on the upper cover plate 41 and is connected between upper cover plate 41, lower cover 42 and in 4 front of the first pull head Between connecting pole 43, the both sides of the intermediate connecting pole 43, which are respectively provided with, can allow sprocket（11、11a）By a left side enter 45 He of channel The right side enters channel 44, and sprocket can be allowed by having at 4 rear portion of the first pull head（11、11a）By and be connected to the left side enter channel 45, The right side goes out channel 46 after entering channel 44.Wherein, the left side enters channel 45, the right side enters channel 44 and after go out channel 46 to form sprocket logical Road, the sprocket channel are substantially in Y-type layout.The sprocket of the left zipper band 1 and the right zipper strip 1a（11、11a）Pass through The left side enters channel 45 and the right side and enters channel 44 and enter in first pull head 4 and go out in channel 46 to converge lock one in the rear It rises.In this way, sprocket can be allowed to latch when 4 upward sliding of the first pull head, otherwise sprocket can be allowed to unbutton.Similarly below The upper left stop member 2 and upper right stop member 3 that will discuss are also to enter channel 45 by the left side and the right side enters described in channel 44 enters Go out in first pull head 4 and in the rear in channel 46 to converge left and right spelling and be close together.

11 head end of sprocket of the left zipper band 1 is provided with upper left stop member 2, in the sprocket 11a of the right zipper strip 1a Head end is provided with upper right stop member 3.The upper of the abjection of the first pull head 4 can be prevented by being provided at the top of the upper right stop member 3 Lug boss 312, the upper projecting portion 312 and the upper right stop member 3 are integrally formed.The upper projecting portion 312 is provided in described Tectosome in upper right stop member 3, can the upper right stop member 3 relatively other regions have bigger transverse width and to Outside extends so as to being stuck on the lateral wall of first pull head 4, or can the upper right stop member 3 relatively other Region has bigger vertical height and upwardly extends so as to be stuck on the upper cover plate 41 of first pull head 4.It is described Upper projecting portion 312 is for when preventing from pulling up first pull head 4, first pull head 4 to cross the upper right stop member 3 and complete Right zipper strip 1a described in total detachment.The top of the upper left stop member 2 corresponds to stage casing region or the hypomere region of the upper right stop member 3 Arrangement.Features described above defines the position relationship between the upper left stop member 2 and the upper right stop member 3, the upper left stop member 2 Top can correspond to stage casing region or the hypomere region arrangement of the upper right stop member 3, but not the corresponding upper right stop member 3 is upper Section region arrangement.Such layout type make when first pull head 4 be moved to 100 head end position of the slide fastener ride up to it is described When in upper right stop member 3 and abutting against the upper projecting portion 312, the upper left stop member 2 can go out after first pull head 4 First pull head 4 is detached from channel 46, so that the left zipper band 1 can also be detached from first pull head 4.

But the upper left stop member 2 can not be allowed de- with first pull head 4 without a hitch under any circumstance It leaves.So upper stop is needed to have the function of the first pull head 4 described in appropriate clamping stagnation.As shown in Figure 4 and Figure 5, the upper left Stop member 2 and the upper right stop member 3 are plastic parts, in the axial direction can with one section when their left and right, which are spelled, to be close together With it is described after go out between channel 46 to be formed the combination wall body section 5 of interference fit, the combination wall body section 5 is rigid structure wall body Section.Features described above defines the design feature of the upper left stop member 2 and the upper right stop member 3, the upper left stop member 2 described first and institute It is the component using plastic manufacturing to state upper right stop member 3, by the material characteristic of plastics to can micro flexible deformation energy Power；Secondly, the combination wall body section 5 of the upper left stop member 2 and the upper right stop member 3 uses rigid structure, i.e., combines harmoniously at described group The elastic construction of elastic-like arm is not provided in body section 5.The elastic construction can be similar patent 201520093267.X In the first common upper being formed in by through-hole section only and in the second function upper stop member in patent 201610137272.5 The fixed elastic arm in both ends on the inside of it；It can also be that one end is fixed, the other end is in the elastic arm of free state.To sum up institute It states, for the combination wall body section 5 not instead of by elastic construction, being obtained by the material physical characteristic of itself can micro elasticity The ability of deformation.As long as going out the cooperation ruler between channel 46 after the combination wall body section 5 and first pull head 4 is rationally arranged It is very little to be interference fitted so that being formed between them.By the interference fit and the upper left stop member 2 and the right side The clamping stagnation positioning of first pull head 4 and described can be thus achieved in micro elastic deformability possessed by upper stop member 3 itself Disengaging between first pull head 4 and the upper left stop member 2.In this way, it is convenient to omit in order to improve the upper left stop member 2 and the right side The elastic deformability of upper stop member 3 and the through-hole section being specially arranged, in patent 201520093267.X first it is common it is upper only It is compared with the second function upper stop member in patent 201610137272.5, upper left stop member 2 of the invention and the upper right stop member 3 Structure is simpler, significantly simplifies the structure of mold.

In the present embodiment, the combination wall body section 5 on transverse width with it is described after go out channel 46 formed be interference fitted. Specifically, the transverse width W1 of the combination wall body section 5 is 6.15mm, and the transverse width W2 that channel 46 is gone out after described is 6.0mm. Of course for make the combination wall body section 5 and it is described after go out to be formed between channel 46 and be interference fitted, can also use another real Apply mode.As shown in fig. 6, the combination wall body section 5a in vertical height with it is described after go out between channel 46 to form interference and match It closes.Specifically, the vertical height H1 of the combination wall body section 5a is 3.38mm, and the vertical height H2 that channel 46 is gone out after described is 3.25mm.Further, be provided on the upper side of the upper left stop member 2a can top pressure to first pull head 4 upper cover plate Small protrusion 21a on 41, be provided on the downside of the upper left stop member 2a can top pressure to first pull head 4 lower cover Small protrusion 22a on 42.In this way by the small protrusion（21a and 22a）Make the upper left stop member 2 and first pull head 4 Interference fit relation is formed between upper cover plate 41 and lower cover 42, and can be reduced the combination wall body section 5a and be drawn with described first Friction area between first 4 and frictional force, to enable first pull head 4 to be more easily detached from the upper left stop member 2a.

In order to realize that upper stop has the function of the first pull head 4 described in appropriate clamping stagnation, can also use another different In above-mentioned by the way of rigid structure.As shown in Figure 7 and Figure 8（In order to distinguish, the upper left stop member label in present embodiment For upper left stop member 2b）, a pair of upper cover plate for capableing of the first pull head 4 described in elastic top pressure respectively is provided on the upper left stop member 2b 41 and lower cover 42 on elastic arm（21b、22b）, on the elastic arm（21b、22b）It is provided with inclined surface（210b、220b）. In this way, by a pair of elastic arm（21b、22b）Equally can the first pull head 4 described in clamping stagnation, make the left zipper band 1 and the right side The sprocket of zipper strip 1a keeps lock state.When first pull head 4 rides up to simultaneously upward sliding on the upper left stop member 2b, institute A pair of elastic arm of top pressure can be distinguished by stating upper cover plate 41 and lower cover 42（21b、22b）The inclined surface（210b、 220b）To make the elastic arm（21b、22b）It mutually draws close so as to allow first pull head 4 to pass through the upper left stop member 2b is simultaneously detached from the upper left stop member 2b.

It, can be with as shown in Fig. 2, the upper right stop member 3 is the component of the maximum upward stroke for limiting the first pull head 4 Using split structure.In the present embodiment, the upper right stop member 3 includes the first upper right stop 31 split above and below and Two upper right stops 32, the second upper right stop 32 are located at the lower section of the first upper right stop 31, stop in first upper right Third upper right stop 33 is additionally provided between portion 31 and the second upper right stop 32.The upper projecting portion 312 and first upper right Stop 31 is integrally formed, is respectively arranged on the upper side of the first upper right stop 31 and downside and extends transversely through setting Groove 331.In this way, the upper right stop member 3 using separate structure can improve the torsion of its own.When first pull head 4 Installed by the groove 331 or when separating the upper right stop member, can be very easy to distort the upper right stop member adjust its Shape on axial direction so that first pull head 4 successfully can be slid into or be slipped away in the groove 331.

As shown in figure 12, the upper right stop member 3 ' can also use integral structure.In order to enhance the upper right stop member 3 ' With the binding force between the right zipper strip 1a ', the sprocket head end of the right zipper strip 1a ' is provided with positional punch 10a ', There is spacing, the upper right stop member 31a ' between the positional punch 10a ' and the inside edge 101a ' of the right zipper strip 1a ' Upper matrix 34 ' and the inside edge 101a ' of inner end 36 ' across the right zipper strip 1a ' of lower substrate 35 ' connect, And outboard end 37 ' is connected across the positional punch 10a '.In such manner, it is possible to increase the upper right stop member 3 ' and the right drawing Binding force between chain belt 1a ' makes the upper right stop member 3 ' that cannot above loose from the right zipper strip 1a ' easily.Separately Outside, the batting in order to prevent on the inside edge 101a ' of the right zipper strip 1a ' expose the upper right stop member 3 ' surface and shadow Appearance is rung, the upper right stop member 3 ' is molded by the thimble top pressure inside edge 101a ' pressures batting by institute again when manufacture State on right zipper strip 1a ', after forming the upper right stop member 3 ' above formed allow evacuation thimble centre hole 38 '.

As shown in figure 9, it is in protrusion respectively that the lower-left stop member 7 and the bottom right stop member 8, which are all in long rodlike and relative inner, Arc.The lower-left stop member 7 and the tail end of the relative inner of the bottom right stop member 8 are provided with positioning concaveconvex structure.Specifically institute The tail end for stating 7 inside of lower-left stop member is provided with locating slot 73, and the tail end of 8 inside of the bottom right stop member is provided with positioning convex platform 83. In this way, determining the depth that the lower-left stop member 7 is inserted on second pull head 6 by the positioning concaveconvex structure.Described The top of bottom right stop member 8 is provided with the lower convex portion 81 that second pull head 6 can be prevented to deviate from.When second pull head 6 moves When moving 100 end-position of the slide fastener and riding up in the bottom right stop member 8 and abut against the lower convex portion 81, the lower-left is stopped Part 7 and the bottom right stop member 8 are all contained in second pull head 6 and its tail end each extends over out the tail of second pull head 6 End, but the lower-left stop member 7 can smoothly extract out from second pull head 6, on the contrary the lower-left stop member 7 also can be smoothly It is inserted into second pull head 6.When first pull head 4 and second pull head 6 are moved to the tail of the slide fastener 100 simultaneously When end, the lower-left stop member 7 and the bottom right stop member 8 are all contained in first pull head 4 and second pull head 6, but institute Stating lower-left stop member 7 can smoothly extract out from first pull head 4 and second pull head 6, otherwise the lower-left stop member 7 It can be smoothly inserted into first pull head 4 and second pull head 6.

Last three kinds that the slide fastener 1 is discussed in detail again unbutton mode：

Enable to complete sprocket unbuttoning from top to bottom when 4 slide downward of the first pull head with hand traction pulling-on piece 47, allows There is the slide fastener 100 the first to unbutton mode.It is moved simultaneously with second pull head 6 when further allowing first pull head 4 To the slide fastener 100 tail end and allow the lower-left stop member 7 smoothly to be taken out with second pull head 6 from first pull head 4 After going out, the left zipper band 1 of entire slide fastener can completely disengage first pull head 4 and be unlocked completely in turn with second pull head 6 Slide fastener 100.

As shown in Figure 10, first pull head 4 is pulled up, first pull head 4 is made to slide into 2 He of upper left stop member In the upper right stop member 3 and allow the upper left stop member 2 and the upper right stop member 3 enter it is described after go out in channel 46.By institute It states combination wall body section 5 and goes out the first pull head 4 described in the interference fit clamping stagnation in channel 46 after first pull head 4, make described the One pull head 4 is located in the upper left stop member 2 and the upper right stop member 3, so as to make the left zipper band 1 and right zipper strip The sprocket of 1a（11、11a）Keep lock state.Described first is set to draw when slightly firmly continuing up drawing first pull head 4 First 4, which squeeze the combination wall body section 5, brings it about micro elastic shrinkage and deforms to go out channel after making first pull head 4 46 continue up and slide and abut against in the upper projecting portion 312 across the combination wall body section 5, and the upper left is stopped at this time Part 2 goes out in channel 46 to be detached from first pull head 4 after described, is drawn so that the left zipper band 1 is also detached from described first First 4.Then it pulls the left zipper band 1 outward respectively and right zipper strip 1a allows sprocket gradually to unbutton from top to bottom, allow the drawing Chain 100, which has second, unbuttons mode.The lower-left stop member 7 is allowed smoothly to extract out to make from second pull head 6 after The left zipper band 1 of entire slide fastener can completely disengage second pull head 6 and then unlock slide fastener 100 completely.

As shown in figure 11, the second pull head 6 described in pushing tow moves it up a small distance from the bottom up, then divides outward Not pullling the left zipper band 1 and right zipper strip 1a can drive second pull head 6 quickly to slide and unbutton from the bottom up Sprocket, second pull head 6 have easy characteristic.Using the easy characteristic of second pull head 6, sutured in the slide fastener 100 In practical application on to surplus the clothes such as left front of surplus down jackets, as long as second pull head 6 is allowed to slide and allow upwards It can be separated naturally between the lower-left stop member 7 and bottom right stop member 8 of slide fastener, it can be by wearer in walking after The active force that clothing lower part is strutted in journey continues that second pull head 6 is allowed to slide upwards, and the lower part of slide fastener is opened to allow clothing It takes portion and forms the skirt structure of jag and then convenient for heat dissipation or walking.When continuing that second pull head 6 is allowed up to be moved to institute When stating the top of slide fastener 100, second pull head 6 is prevented by first pull head 4 and cannot be detached from the upper left stop member 2, Although whole slide fastener is substantially opened but not completely disengages at this time, to easily facilitate heat dissipation and walking, clothes energy is allowed With being enough reliably retained in.Allow the slide fastener 100 that there is the third to unbutton mode.Thus it has also been discovered that, default pulling-on piece Second pull head 6 do not influence sprocket from the bottom up quickly unbutton.And from the appearance point of view, default pulling-on piece it is described Second pull head 6 makes slide fastener 100 seem more flexible, small and exquisite, changes the appearance of previous two-way separating zip burden.

It can be seen that the slide fastener 100 for facilitating double end to disengage of the present invention is skilful two-way separating zip structure and Yi Tuo zippers Combine wonderfully, not only make the slide fastener 100 be provided with above-mentioned three it is different unbutton mode, be also the slide fastener under Unbuttoning up proposes more easily mode, extends the applicability of the slide fastener 100.
