Example 1:
This example relates to slide fastener 101 and sliding part 115, and it is set to the replacement of tooth class slide fastener, can be included in clothes, clothes article, belt, clothes annex or other.
Slide fastener rail-slide fastener 101 comprises slide fastener rail 102 and zipper slide part 115 longitudinally.With reference to figure 4, slide fastener rail 102 of the present invention is except a series of gaps 180, and each has substantially along the constant cross section of its whole length.Slide fastener rail 102 forms the part of clothes part or is installed to the part of described clothes, and described clothes have the ability that is connected and separated by slide fastener 101 of the present invention.
For example, when slide fastener 101 of the present invention was included in the jacket with front located opening, slide fastener 101 can be included in two anters of jacket forward part, provided branch opening tag (jacket formula) slide fastener-see Fig. 4 A to allow jacket to untie with closure.
Positive and cloudy rail-slide fastener rail 102 comprises positive slide fastener rail 103 and cloudy slide fastener rail 104.Sun slide fastener rail 103 is mainly defined by its functional character (for positive profile 105), and it can combine and break away from combination with the cloudy profile 106 of cloudy slide fastener rail 104 in the sliding part.The cloudy profile 106 of cloudy at least slide fastener rail 104 is made by bullet flexibility (resiliently flexible) material.Suitable elastic materials for example plastic material is used to define the cloudy profile 106 of cloudy slide fastener rail 104.
Each outline portion 105,106 defines along the longitudinal edge 107 of the flange 108,109 of positive slide fastener rail 103 and cloudy slide fastener rail 104 respectively.Each flange the 108, the 109th is set, is combined in the clothes in order to allow positive slide fastener rail 103 and cloudy slide fastener rail 104.Flange the 108, the 109th is set, for by make, ultra-sonic welded, adhesives etc. be fixed on the part of clothes.
Sun slide fastener rail 103 and cloudy slide fastener rail 104 can be made of two independent parts, and they have contour feature 105,106 and flange 108,109.
Replacedly, positive slide fastener rail 103 and cloudy slide fastener rail 104 each can manufacture whole part.Slide fastener rail 103,104 can be by forming around each segmentation of band injection molding.
Because the cross section of positive slide fastener rail 103 and cloudy slide fastener rail 104 is preferably constant substantially along its whole vertical (along direction LL) length, so the extruding of slide fastener rail 103,104 is suitable methods of making them.
Two kinds of selections
After Yang Heyin slide fastener rail is extruded, below can forming at one of described sun and cloudy slide fastener rail or among both at the optional groove or the gap of the extensile formal description of slide fastener.It is that if slide fastener is designed to anti-substantially water or fluid barrier is provided, so preferably, positive and cloudy profile is continuous (not segmentation) along its length all, or the partly segmentation of positive profile, as long as positive profile is completely contained in the continuous fluid-tight cloudy profile just to become.
The shape of profile-in this example, cloudy profile 106 and positive profile 105 are cup and spherical.Yet, also can imagine the replaceable shape of such profile, and the profile of the best of having tested is the profile that example 2 is described.It is avette or oval-shaped profile almost.
Sliding part-can make positive profile 105 and the easy degree that cloudy profile 106 combines in order to increase is provided with sliding part 115, so that positive slide fastener rail 103 and cloudy slide fastener rail 104 combinations and disengaging combination.Sliding part 115 is for can be by user's hand or refer to the element held, allow the user along slide fastener rail 103,104 at longitudinal direction LL slip sliding part.Sliding part can have the pulling-on piece that is installed to sliding part, with easy in order to use.
Sliding part 115 and positive slide fastener rail 103 and 104 engagements of cloudy slide fastener rail.Such engagement is because outline portion 105,106 is captured in the result of inside of the gathering sill 116,117 of sliding part 115.Described gathering sill shape of cross section (horizontal direction of LL along the longitudinal direction) enough is enough to hold the respective profile part of positive slide fastener rail 103 and cloudy slide fastener rail 104 greatly, yet enough limited to prevent that the outline portion that so is captured in gathering sill 116 and 117 from separating with sliding part along horizontal direction TT.In this example, be used for that the gathering sill 116 of cloudy profile is basic to be circular the shape of slide fastener rail outline portion (or corresponding to) cross section, similarly, the gathering sill 117 that is used for positive profile also is almost circular cross section along its length.Each groove comprises opening 118,119, and opening 118,119 allows flange 108,109 therefrom to pass through respectively.Sliding part along slide fastener rail 102 along the longitudinal direction LL move positive slide fastener rail 103 and cloudy slide fastener rail 104 operated toward each other so that their combination and break away from combination.
At first end 120 of sliding part 115, positive slide fastener rail 103 and cloudy slide fastener rail 104 stretch out from sliding part 115 with the state that separates.Second end 121 at sliding part 115, sun slide fastener rail 103 and cloudy slide fastener rail 104 stretch out from sliding part 115 with the state of combination, for example as shown in Figure 5, translation takes place in 121 at first end 120 of gathering sill 116,117 and second end, because the combination of gathering sill 116,117, this causes outline portion 106,105 together.
Preferably, sliding part 115 is provided with the expander element, describes it in further detail with reference to following example 2.Still preferably, when groove when each end of sliding part 115 extends, the cross-sectional area expansion of cloudy gathering sill 116, with reference to curve detailed among the figure 4 270, it shows this increase of the cross-sectional area of cloudy gathering sill 116.When cloudy gathering sill 116 when the end to end of groove is advanced, the expansion of the cross-sectional area of cloudy gathering sill 116 and subsequently position and the geometry of dwindling to a certain extent corresponding to the expander element that is positioned at identical groove.This change of cross-sectional area is designed to can hold the expansion of cloudy profile 106 when cloudy profile 106 is expanded by cloudy gathering sill 116 and by expandable element.
The extensibility of the profile of optional segmentation-in order to strengthen longitudinal flexible and also to strengthen longitudinal direction LL, at least cloudy profile 106 is defined and made by a kind of material: described material has sufficiently high rigidity firmly catches positive profile 105 and stops removing of described positive profile 105 to allow it, also will have the series of grooves or the gap 180 that are spaced apart along its length.
Preferably, the described gap horizontal direction extension of LL along the longitudinal direction.Therefore, cloudy profile 106 does not have continuous and constant cross section (the horizontal direction of LL along the longitudinal direction), and this is because it is provided with a plurality of such gaps 180.Preferably, the entire portion of the element of described gap 180 by defining cloudy profile 106, separately each profile portion assigns to it is defined as discrete part.
Extensibility selects-is set at cloudy profile 106 under the situation of a series of and/or the discrete part arranged, and the extending longitudinally of cloudy rail 104 is no longer defined or is limited by the character of the material that defines cloudy profile 106.The character of the material of the material of flange 109 or holding flange for example limits the extensibility of cloudy rail 104 along direction LL so just.
Be arranged in extensilely during with 109 edge at discrete cloudy profile 106, for example made by the band of cutting sth. askew, neoprene, lycra or other material, the extending longitudinally of so cloudy rail 104 can be significant.When cloudy rail 104 stretched and be lax, the gap 180 that is arranged between the contiguous discrete cloudy profile element 106 can expansion and contraction.Except increasing the autgmentability by being arranged on the interelement gap of defining cloudy profile 106, the flexibility of cloudy rail 104 also obtains increasing.
Depend on the selection of carrying material and its extensibility along the span of slide fastener length.Use for great majority, the extensibility that preferably limits slide fastener (therefore band) is not more than 25%.For neoprene wet type clothes, the stretching, extension factor of slide fastener is 15% to 20% normally enough.
Preferably, those elements of cloudy profile 106 can be fully separately defined in gap 180, but replacedly, only separately define the part of each element of cloudy profile 106.Extending longitudinally may not be necessary or the situation of the feature of expectation under, the element that defines cloudy profile 106 still can be installed in for example base portion, described base portion they along the edge placement of flange 10.Be arranged on cloudy profile 106 in the gap along under the situation between those zones of ridge 181, the plane that still can realize bending flange 109.Yet for flexibility and extensibility, the element that defines cloudy profile 106 is for discrete each other.Gap 180 can be provided with along cloudy rail 104 at regular intervals, or can only be arranged on the flexibility of needs expectation and/or the position of extensibility.
Depend on application, preferably, cloudy at least profile is made (this is because it need have the suitable amount of the good material of bending resistance to guarantee that it can keep positive profile 105 engagements) by such discrete component.Yet positive profile 105 can be arranged to discrete section, as for example shown in Figure 4.Although positive profile 105 does not need to have the material with cloudy profile 106 identical rigidity, connect and stop it separately to set up brute force between sun and the cloudy profile, yet further strengthen the extensibility and the flexibilities of slide fastener rails 102 along the gap 180 that positive profile 105 is provided with along the horizontal direction of direction LL.Flange can similarly be installed and be arranged in to sun profile 105 or with 108 edge, flange or with 108 material thereby define the extensibility of positive rail 103 and definite feature of flexible nature.The flexibility of described rail is subjected to the influence of the size in gap 180, so the gap is big more, and the flexible radius of positive and cloudy rail is tight more.
Because cloudy rail 104 and/or positive rail 103 are injection molding, and gap 180 can be set.Replacedly, at cloudy rail 104 and/or positive rail 103 or outline portion the 105, the 106th, under the situation about being squeezed into, after extruding, can define gap 180.Laser cutting or machine cut can be for defining the only method in these gaps 180.Although groove is arranged in cloudy profile 106 and the positive profile 105, however the impossible watertightness that realizes slide fastener 101; The groove 180 by positive profile 105 is set in different interval rather than the gap 180 of cloudy profile 106, the improvement that can produce watertightness.Guarantee in gap 180 with different interval, only several gaps (register) aligned with each other at any one time of each sun and cloudy profile.When it is aligned with each other, clearly,, can between positive rail 103 and cloudy rail 104, set up without any waterproof sealing in such position.
Whole length has under the situation of continuous and constant cross section along it at positive profile 105, sets up waterproof sealing so between positive rail 103 and cloudy rail 104.Replacedly, vertical relative positioning at positive rail 103 and cloudy rail 104 is repeatably constant, be closed end (trousers type) slide fastener for example at (a) slide fastener, or (b) slide fastener comprises under the situation of the end stop 184 shown in Fig. 4,5 and 8 for example, and the gap 180 that each positive profile 105 and cloudy profile 106 can be set is to keep misalignment.This end stop 184 can be stopper or stopper, it be installed to last cloudy section 181 with stop sliding part leave cloudy rail " on " end.
The size example
Should be understood that the most of ratio of accompanying drawing, with the shape and the function of a plurality of parts that the slide fastener fastener that constitutes this example is shown for amplifying.The slide fastener fastener of this example can be made multiple formation, size and length to be fit to the final use of product.Yet in order to understand the relative size of described parts, it is long for the clothes designed standard slide fastener fastener of 100mm to 500mm to be based upon typical slide fastener, provides following size.Providing of these sizes is exemplary purely, and is not intended to limit the scope of the invention by any way.

Example 2:
This example class is similar to example 1; Just the shape of the male element shape that more resembles an arrow and female element more resembles a triangle.Slide fastener 201 comprises vertical slide fastener rail 202 and sliding part 215.With reference to Figure 11, slide fastener rail 202 of the present invention is except a series of gap 280A, and each has substantially along the constant cross section of its whole length.Slide fastener rail 202 forms the part of clothes part or is installed to the part of described clothes, and clothes have the ability that is connected and separated by slide fastener 201 of the present invention.For example, when slide fastener 201 of the present invention was combined in the jacket with front located opening, slide fastener 201 can be included in two anters of jacket forward part, untied and closure to allow jacket.
Positive and cloudy slide fastener rail-slide fastener rail 202 is made up of positive slide fastener rail 203 and cloudy slide fastener rail 204.
Sun slide fastener rail 203 is mainly defined by its functional part, and said functional part is positive profile 205, and it can combine with the cloudy profile 206 of cloudy slide fastener rail 204 and break away from combination.
Preferably, the cloudy profile 206 of cloudy at least slide fastener rail 204 is made by playing flexible material.Depend on application, appropriate plastic material or elastomeric material (or both combinations) can be used for defining the cloudy profile 206 of cloudy slide fastener rail 204.Appropriate plastic material can comprise polyethylene and polyvinyl chloride.Can use other plastics.The selection of plastics depend on its characteristic and be used for the adaptability of final use, around the tensile strength of flexibility with molded easiness, flexibility and extensibility and expectation.
Preferably, each outline portion 205,206 defines along the longitudinal edge 207 of the flange 208,209 of positive slide fastener rail 203 and cloudy slide fastener rail 204 respectively.Each flange the 208, the 209th is set, is included in the clothes in order to allow positive slide fastener rail 203 and cloudy slide fastener rail 204.Flange the 208, the 209th is set, for by the part of making, ultra-sonic welded, adhesives etc. are fixed to clothes.Sun slide fastener rail 203 and cloudy slide fastener rail 204 can be made of two independent parts, and they are molded component 205,206 and flange 208,209.Replacedly, positive slide fastener rail 203 and cloudy slide fastener rail 204 each can manufacture whole part.Slide fastener rail 203,204 forms or makes by injection molding by extruding, mixing extruding.Because the cross section of positive slide fastener rail 203 and cloudy slide fastener rail 204 is a basically identical along its whole vertically (along direction LL) length preferably, so the extruding of slide fastener rail 203,204 is suitable methods of making them.Groove or gap can be described below in this article, can form in one of described sun and cloudy slide fastener rail or both after the extruding.
The profile of the shape of profile-tested is shown in Figure 13 and 14.Sun profile 205 seems a bit picture arrow, but has circular nose.Its leading edge is that part is oval.Sun profile 202 has a pair of flange recessed at the rear portion.Cloudy profile 206 comprises groove 210, and groove 210 is LL along the longitudinal direction also, extends along the length of cloudy slide fastener rail 204.It is in order to allow positive profile 205 therefrom to pass through, so that positive profile 205 and 206 combinations of cloudy profile and disengaging combination that described groove is set.The inside of cloudy profile 206 is the shape with the shape complementarity of positive profile 205.Cloudy profile provide shape of cross section corresponding to but less times greater than continuous (or semi-continuous) chamber of the size of positive outline portion.
In the first long model of 50mm, have with the recessed characteristic of the pawl 211 of the flange 212 coefficient cloudy profiles 206 of positive profile 205 and to surpass 15 kilograms tensile strength (resistance that the length of relative slide fastener is drawn back with the right angle).The selection and the flexibility of appropriate designs by contour shape and the material that uses in zipper fabrication can change this tensile strength.In some cases, low tensile strength can be favourable (for safety), and in other cases, high-tensile can be expected.
Sliding part-can make positive profile 205 and the easy degree that cloudy profile 206 combines in order to increase the present invention includes sliding part 215, so that positive slide fastener rail 203 and cloudy slide fastener rail 204 combinations and disengaging combination.
Sliding part 215 (with reference to the accompanying drawings 22) has pulling-on piece 231, described pulling-on piece 231 radial types are connected to outer lug portion 230, and be designed to can be by user's hand or refer to the element held, and allows the user along slide fastener rail 203,204, the sliding part of LL slip along the longitudinal direction.Sliding part 215 and positive slide fastener rail 203 and 204 engagements of cloudy slide fastener rail.Such engagement is because outline portion 205,206 is captured in the result in the gathering sill 216,217 of sliding part 215.
Described gathering sill shape of cross section (horizontal direction of LL along the longitudinal direction) enough is enough to hold the respective profile part of positive slide fastener rail 203 and cloudy slide fastener rail 204 greatly, yet enough limited to prevent that the outline portion that is captured in gathering sill 216 and 217 from separating with sliding part along horizontal direction TT.The gathering sill 216 that is used for cloudy profile as shown in figure 15, its shape is corresponding to the shape of cloudy profile 206 shown in Figure 13.Similarly, be used for the shape of gathering sill 217 shapes of positive profile corresponding to positive profile 205 shown in Figure 14.
More greatly to allow cloudy profile expansion, this is described below the cross-sectional area that it should be noted that cloudy gathering sill around the expandable element 226 of torpedo shape.With reference to the curve 270 of figure 4 detailed descriptions, it shows cloudy gathering sill when each end of sliding part 115 extends equally, and how its cross-sectional area increases.In improved sliding part 226A shown in Figure 25, this also is tangible.
Figure 21 a shows positive gathering sill 216 and the cloudy gathering sill 217 and the extension member 226 of profile with viewgraph of cross-section.In this figure as seen, bridge 228 is connected to Center Island part 227 with extension member 226.Center Island part 227 is the material of sliding part 215 substantially, and it is between positive gathering sill 216 and cloudy gathering sill 217.In this view, can see that when leaving first end 220 of crotch region (not shown) to sliding part 215 and extend, positive gathering sill 216 and cloudy gathering sill 217 are bifurcated.
Sliding part along slide fastener rail 202 along the longitudinal direction LL move, positive slide fastener rail 203 and cloudy slide fastener rail 204 are operated toward each other, so that their combination and break away from combination.At first end 220 of sliding part 215, positive slide fastener rail 203 and cloudy slide fastener rail 204 extend from sliding part 215 with the state that separates, shown in Figure 20 and 30.
Directly continue to use in the gathering sill 216 of cloudy profile and extend beyond its zone 225, comprise the into expandable element 226 of a torpedo-shaped, begun to be used for the bifurcated of the gathering sill 216 of cloudy profile in zone 225.
Also can see such expansion with reference to Fig. 9 A.When cloudy profile 206 when gathering sill 216 advances, the expansion of the expansion of gathering sill 216 and described cloudy profile 206 shapes matches.Although whole length along gathering sill 216, the shape suitable at state and the cloudy profile of expansion fully has constant cross section also can be fit to, yet preferably, and keep fully being captured in the gathering sill 216 in order to ensure cloudy profile, described cross section still can change really at the length range of gathering sill 216.
For at cloudy profile with before positive profile combines, as long as putting into practice possible distance range, expandable element 226 keeps in touch with cloudy profile 206, can see that expandable element 226 extends partially into the path of the positive profile that is defined by gathering sill 217 at least.
Preferably, expandable element 226 comprises otch 238 near the end of second end 221, and it has the shape that allows positive profile 205 to pass through in its vicinity.Yet in case sun and cloudy profile do not need 226 pairs of cloudy profiles 206 of expandable element what influence is arranged in the not land 239 basic combinations of the guide rail 216,217 of bifurcated.
Should understand, although mainly the combination of positive profile and cloudy profile is described at this, the disengaging of sun profile and cloudy profile is in conjunction with operating in the opposite mode of having stated with this specification substantially of mode, promptly in the zone of gathering sill 216 and 217 bifurcateds, expander is expanded cloudy profile 206 and is left positive profile 205.
The disengaging combination-when slide fastener is closed, extend (in this situation from first end 220 of sliding part on the top of sun profile and cloudy profile, the slide fastener of jacket type is can be fully closed because the sub-fraction of positive profile and cloudy profile always separate-different with the aspectant sealing in slide fastener is locked plastic tape).Therefore, sliding part causes that along downward the moving of slide fastener positive profile and cloudy profile are by gathering sill and disengaging combination, no matter whether expandable element is arranged in cloudy gathering sill.Yet by an end suitable shaping of expandable element in the face of end 221, it is possible assisting to break away from the operation of combination and helping cloudy profile to open when separately the place moves apart male element at gathering sill when it.
By by Bao Qiao the expandable element that the is shaped side from guide rail being separated suitably, to fit in when entering the state that breaks away from combination around the described bridge portion be possible to the pawl of cloudy profile when it is lax, thereby described bridge portion enough approaches to pass through the groove 210 of cloudy profile.
Positive profile and cloudy profile break away from conjunction with the time, the edge foremost of sliding part is second end 221.Sliding part 215 total maintenance, contact with cloudy guide rail 204 with positive guide rail 203, and when slide fastener rail 202 during along the state of its whole substantially length in complete combination, described sliding part is arranged on the upper end of slide fastener rail 202.
Preferably, described sliding part is formed by the plastic material injection molding such as the low friction of PTFE (polytetrafluoroethylene (PTFE)) etc., move easily to allow sliding part, and expandable element inserts cloudy profile.
Another form of expandable element is shown in Figure 25 and 26.Be more sharp-pointed wedge shape, be designed to enter the groove and the inside of cloudy profile, and allow its expansion to be enough to bite positive profile.End stop can be arranged on the slide fastener rail, exceeds and the slide fastener rail 202 that slips away to stop sliding part 215 to slide.Sliding part 215 causes positive profile 205 and cloudy profile 206 to break away from combination to the advancing of the other end of slide fastener rail 202.
The profile of optional segmentation-in order to strengthen longitudinal flexible, and the extensibility that preferably also strengthens longitudinal direction LL, at least cloudy profile 206 is defined and made by such material: firmly catch positive profile 205 and stop removing of described positive profile 205 to allow it although it has sufficiently high rigidity, it also has series of grooves or the gap 280 that is spaced apart along its length.
Preferably, gap 280 is in the extension in a lateral direction of longitudinal direction LL.Therefore, cloudy profile 206 does not have continuous and constant cross section (at the horizontal direction of longitudinal direction LL), and this is because it is provided with a plurality of such gaps 280, but it is what repeat.Preferably, the entire portion of the element of gap 280 by defining cloudy profile 206, separately each profile is defined as discrete part with it.Be set at cloudy profile 206 under the situation of a series of and/or the discrete part arranged, the extending longitudinally of cloudy rail 204 is no longer defined or is limited by the character of the material that defines cloudy profile 206.Yet be the character of the material of the material of for example flange 209 or holding flange, limit the extensibility of cloudy rail 204 on direction LL.Be arranged at discrete cloudy profile 206 under the situation at edge of neoprene for example or lycra flange 209, the extending longitudinally of cloudy rail 204 is significant.When cloudy rail 204 stretched and be lax, the gap 280 that is arranged between the contiguous discrete cloudy profile element 206 can expansion and contraction.Except increasing the extensibility by being arranged on the interelement gap of defining cloudy profile 206, the flexibility of cloudy rail 204 also obtains increasing.Those elements of cloudy profile 206 can be preferably fully separately defined in gap 280, but in interchangeable scheme, also can only separately define the part of each element of cloudy profile 206.Extending longitudinally perhaps be not too important or the situation of feature of expectation under, the element that defines cloudy profile 206 still can be installed in for example base portion, they are along the edge placement of flange 209 at this.Be arranged on along under the situation between those zones of the cloudy profile 206 of ridge 281 plane that still can realize bending flange 209 in the gap.Yet for flexibility and extensibility, the element that defines cloudy profile 206 is discrete each other.
Gap 280 can be provided with along cloudy rail 4 at regular intervals, or can only be arranged on the flexibility of needs expectation and/or the position of extensibility.Although most important ground, cloudy profile is preferably such discrete component (this is can keep the suitable amount that meshes with positive profile 205 because it need have the good material of bending resistance to guarantee it), yet positive in addition profile 205 can be arranged to discrete section, shown in for example Figure 20 and 21.Although positive profile 205 does not need to have the material with cloudy profile 206 identical rigidity, with set up strong connection between positive profile and the cloudy profile stop its along on the horizontal direction of direction LL separately, yet further strengthen the extensibility and the flexibilities of slide fastener rails 202 along the gap 280 that positive profile 205 is provided with.Sun profile 205 can similarly be installed to and be arranged in the edge of flange 208, and the material of flange 208 is the material that defines definite feature of the extensibility of positive rail 203 and flexible nature.Very clear, the flexibility of described rail is subjected to the restriction of the size in gap 280, so the gap is big more, and positive rail and the flexible radius of cloudy rail are tight more.
The result that gap 280 can be used as cloudy rail 204 and/or positive rail 203 injection moldings is provided with.Replacedly, at cloudy rail 204 and/or positive rail 203 or outline portion the 205, the 206th, under the situation of extrusion modling, gap 280 can define after extruding.Laser cutting or machine cut can be for defining the only method in these gaps 280.Although be arranged on result in cloudy profile 206 and the positive profile 205, can not realize the watertightness of slide fastener 201 as groove; Yet the groove 280 of the positive rail 205 by the interval different with the gap 280 of cloudy profile 206 is set, the improvement that can produce watertightness.Gap 280 with different interval guarantees that only several gaps of each positive profile and cloudy profile are aligned with each other at any one time.When it is aligned with each other, very clear, in such position, can between positive rail 203 and cloudy rail 204, set up without any waterproof sealing.
Whole length has under the situation of continuous and constant cross section along it at positive profile 205, then can set up waterproof sealing between positive rail 203 and cloudy rail 204.Replacedly, for to continue repeatably, for example comprise under the situation of upper end retainer that the gap 280 that each positive profile 205 and cloudy profile 206 can be set is to keep misalignment at slide fastener at vertical relative positioning of positive rail 203 and cloudy rail 204.
Close the tail slide fastener: if the slide fastener fastener is designed to close the tail slide fastener, the slide fastener of trousers type (or slide fastener of belt type) for example, by making in the mode similar to the slide fastener of prior art, an end of two profiles part generally can be bonded together with suitable manner so.The other end (top) that end stop can be arranged on outline portion be captured in outline portion one of at least on sliding part.In most of the cases, this is cloudy profile.
Separating zipper (slide fastener of jacket type): be not bonded together in two profiles parts and separate fully allowing, under the situation as the slide fastener of jacket type, end stop can be arranged on each end of zipper profiles part so.Preferably, at least one end of outline portion has locking device, is used for the slide fastener rail is locked into together, to stop vertically moving that the sun rail slides and skids off then when slide fastener is closed in cloudy rail.
The end stop of any kind can be used for keeping sliding part on rail, and the two ends of slide fastener rail are aimed at.Can use traditional bottom retainer design.Novel end stop is described now.This end stop is designed to " locator ", and is designed to stop that positive rail and cloudy rail are opposite vertical moves.
The bottom retainer: because positive slide fastener rail 103 and cloudy slide fastener rail 104 are the type that the profile of unanimous on the whole or repetition is arranged along its length, therefore, except that the result of friction, to opposite vertical slip on direction LL, the slide fastener rail does not provide resistance.
Under slide fastener 101 is bonded to situation in the jacket for example,, need can be set separating completely of slide fastener rail with reference to Figure 28.Thereby one of for example positive rail 103 and cloudy rail 104 for good and all can not be locked in together in the end of rail (as the closed type slide fastener, for example the situation of trousers type slide fastener).
Yet people expect to have temporary transient tightening device, come the described rail of fastening stoping their relative motions in the vertical, thereby clothes can keep aiming at.
A mode that realizes this expectation is combined with slide fastener retainer 160 for the end at slide fastener rail 102, as shown in figure 29.Slide fastener retainer 160 comprises latch 168 and pin case 161, can be the type that is similar to those parts that on tooth-like slide fastener rail, have (use term " pin case " to show that these parts appear at the similar position of pin case to traditional tooth-like slide fastener fastener, but our pin case being carried out different functions and had different shapes).
Therefore, in case when being accommodated in groove or the recessed portion 165, the end 166 of positive slide fastener rail 103 is hunted down and stops its moving in a lateral direction at longitudinal direction LL.Groove or recessed portion 165 have such shape: it comprises the zone that the positive profile 105 with positive rail 103 matches and is included in its outside opening that the flange 108 of positive slide fastener rail can pass through described opening.Be set at pin case 161 under the situation of one of positive slide fastener rail 103 and cloudy slide fastener rail 104, cloudy slide fastener rail and positive slide fastener rail moving on the direction of one of longitudinal direction LL can be stoped.
Yet under without any situation about further strengthening, still might occur between positive slide fastener rail 103 and the cloudy slide fastener rail 104 along the relative motion on the opposite direction of axle LL.This direction will make within the groove 165 of end 166 self-marketing casees 161 of positive slide fastener rail 103 engagement separately.
In order to stop positive slide fastener rail 103 to move along this direction, positive slide fastener rail 103 is provided with latch 168, and it can utilize brake component 169 location of for example selling case 161.Latch 168 comprises a surface, described surface be used for when the end 166 of positive slide fastener rail 103 its longitudinal direction LL suitably or when on its whole degree, being positioned in the recessed portion 165 and surface of brake component 169 be meshing with each other.
Mode and latch 168 engagements that brake component 169 bounces back with the groove 165 that prevents terminal 166 self-marketing casees 161.Preferably, the mode that is arranged as with similar snap fit of latch 168 and brake component 169 plays a role.When positive slide fastener rail 103 advances when making its end 166 be engaged in the groove 165 by moving at direction LL with respect to cloudy slide fastener rail 104, brake component 169 also advances at direction LL, up to aliging with brake component 169, therefore is bited into the relation of interference.
In order to allow separating of latch 168 and brake component 169, but latch 168 comprises the end 171 of grasping, and it demonstrates the finger control latch 168 that allows the user, so that it separates with brake component 169.Therefore end 171 presents the finger of permission by the user makes the horizontal direction displacement of latch 168 at longitudinal direction LL, with the interference surface of slip brake part 169 and latch 168, allows positive slide fastener rail 103 to remove the engagement of self and groove 165 thus.
Stretch out or the gripping of the outstanding finger that is enough to make things convenient for the user or use at least the end 171 of latch 168, separates with brake component 169 to allow latch 168.Although under most preferred form and as shown here, pin case 161 is arranged on the end of cloudy slide fastener rail 104, yet replacedly, also can be arranged on the end of positive slide fastener rail 103, and latch 168 can be set to cloudy slide fastener rail.
The size and dimension of this end stop 160 allows hole 190 to place by pin case 161, encloses skiing ticket or other ticket or identification label.
In order to increase the easiness that positive profile 105 is combined with cloudy profile 106, the present invention can be in conjunction with sliding part 115, so that positive slide fastener rail 103 and cloudy slide fastener rail 104 combinations and disengaging combination.
Sliding part 115 is an element, and described element can or refer to holding by user's hand, and allows the user along slide fastener rail 103,104, and sliding part slides on longitudinal direction LL.Sliding part 115 all meshes with positive slide fastener rail 103 and cloudy slide fastener rail 104.Such engagement is because profile 105,106 is captured in the gathering sill 116,117 of sliding part 115.
Described gathering sill shape of cross section is enough big, is enough to hold the outline portion separately of positive slide fastener rail 103 and cloudy slide fastener rail 104, yet enough limited to prevent that the outline portion that is captured in gathering sill 116 and 117 from separating with sliding part at horizontal direction TT.The gathering sill 116 that is used for cloudy profile has the oval-shaped cross section of part substantially, and similarly, the gathering sill 117 that is used for positive profile also has along the cross section of its length essential part ellipse, thereby they are corresponding to the shape of two profiles part.
Each gathering sill 116 and 117 comprises opening 118,119, and described opening 118,119 allows flange 108,109 therefrom to pass through respectively.Sliding part moves on longitudinal direction LL along slide fastener rail 102, and positive slide fastener rail 103 and cloudy slide fastener rail 104 are operated toward each other, so that combination and disengaging combination.At first end 120 of sliding part 115, positive slide fastener rail 103 and cloudy slide fastener rail 104 extend from sliding part 115 with the state that separates.At second end 121 of sliding part 115, positive slide fastener rail 103 and cloudy slide fastener rail 104 extend from sliding part 115 with the state of combination, for example as shown in Figure 5.Translation takes place in 121 at first end 120 of gathering sill 116,117 and second end, because the combination of gathering sill 116,117, this causes outline portion 105,106 together.
Alternatively, be used for opening, from its centerline offset, to allow the outside of latch 168 by sliding part at the rail of the end 121 of sliding part.In order to prevent that latch 168 and sliding part from bumping against, also from its positive rail 105 offset or dish X, as shown in figure 29, and described latch preferably is installed to the band or the flange of positive profile to described latch, thereby when sliding part was inserted in the end of positive profile, it can walk around sliding part.
The gap that the end of sun rail 105 and latch are 168 is enough to allow sliding part 115 therefrom to pass through.
Partial aperture-, show change to the cloudy profile 206A of constant in addition cross section with reference to Figure 24.In the case, gapped or floating trough (relief slots) 280A not exclusively forms by cloudy profile.Groove 280A is set by cloudy profile, purpose is to weaken along perpendicular to flange or with the moment of flexure intensity of the direction on 209 plane, to increase the flexibility of cloudy slide fastener.In this way, cloudy profile no longer needs to comprise discrete element as shown in figure 23, and this is because cloudy profile dies down to allow the edge perpendicular to the plane of flange 209 and the easier bending in plane of longitudinal extension.Should be understood that in this structure, because cloudy profile is not an element separately, therefore the material of cloudy profile influences the extensibility of cloudy slide fastener rail.
Oval sun section-, show change to sun section 305 shapes with reference to Figure 31.In this form, described section is essentially oval-shaped substantially.Become circle by the end that makes sun section 205, might allow sun section and cloudy intersegmental bigger gap, increase extensibility and flexibility, make the leading edge of sun section 305 be trapped in risk minimization in the gap 380 of 306 of cloudy sections simultaneously.
Although preferably make sun section and cloudy section, also might sun section (particularly these oval sections 305) be made of metal and be crimped onto described being with by plastic material.
The sliding part that is used for the change of wedge profile is a wedge shape at the outline portion of male element at least, thereby has the narrow summit along its length, can enter under the situation of groove of cloudy profile, can omit expandable element.Figure 32 is the partial section that does not have the sliding part of expandable element, and its shows the outline portion of the short part enter sliding part, and the outline portion of combination that leaves the short length of sliding part.According to the way that the inventor uses, demonstrate cloudy profile the right, and positive profile is on the left side of sliding part at sliding part in these accompanying drawings.Rail by considering basic " Y " shape and in conjunction with the angle should notice that the relative size, shape of positive profile and " acutance " allow it to enter cloudy profile, even at its " closure " state.When entering groove, the shape of positive profile allows its wedge in conjunction with the border in the bigger chamber of rail to open cloudy profile, thereby two profiles part moves on basic crooked passage together, and the channel part of described basic bending is determined by the geometry of the rail in the sliding part.When sliding part when the jacket slide fastener of type shown in Figure 33 moves up, all this situations take place.When sliding part along described slide fastener move down and the bottom of positive profile when sliding part is removed, combination takes place to break away from.Construct as shown in figure 33 the bottom of sun profile, thereby easily positive profile insertion sliding part is rejoined described slide fastener.The top and the bottom of cloudy profile have end stop, are used for sliding part is remained on cloudy profile.The top of sun profile also can have end stop.
In most of the cases, it is round as a ball that the summit of positive profile becomes, but main body is the cardinal principle wedge-type shape, and this is because the inventor finds that this is to be used for the most effective shape of positive profile.
In most of the cases, it is advantageous having the monoblock type plastic flange of extending from the bottom of positive at least profile, this is the latch that provides sufficiently rigid substrate to be used for end stop because of this help, and provides sufficiently rigid part to help the bottom of fixing described positive profile when sliding part is inserted in the bottom of positive profile.

Industrial applicibility
The present invention relates to novel slide fastener fastener, be particularly suitable for the clothes manufacturing and be used for bag and footwear.
Advantage
The slide fastener fastener of the novelty of these examples can be designed to extensible, or anti-substantially water.These advantages come from the design of sliding part and the shape of positive profile and cloudy profile.Described sliding part has guider in sliding part, is suitable for guiding positive profile and the combination toward each other of cloudy profile, and allowing cloudy profile to be enclosed within on the positive profile and to catch positive profile, thereby two rails combine into closure state.
The shape of the optional expandable element in cloudy profile and/or the sliding part allows cloudy profile to be opened and slides on the positive profile, and the power that does not need too much power and do not need to apply closed cloudy profile.The elastic property of cloudy profile allows it to spring back to its inactive state, and that the back taken place is closed and keep positive profile to be captured in the inside around positive profile engaging.
The sun profile can be formed by different materials with cloudy profile, or has different characteristics.They can form by injection molding around the advanceable band that curls.The relative size of sun profile and cloudy profile and relative friction or static resistance are so that in case to engage the relative slip of two profiles part be thereby that difficult described rail maintenance is advisable in position.Perhaps, end stop can be used at least one end of the described rail of grappling to prevent the relative slip of described rail.
The continuous characteristic of the new slide fastener of describing in this specification can provide ratio such as the towing still less of tooth-like slide fastener.For the slide fastener that uses on sportsman's clothes, this feature possibility particular importance, the sportsman needs minimum towing, for example swimmer, slider and triathlete.
The slide fastener of prior art must enough softly not need significant power that described outline portion is pushed away together to allow outline portion to slide into suitable position, but this limits or reduced the oss-divided resistance of anti-described rail simultaneously.If the intensity of material increases, although so anti-oss-divided resistance increases, vertical hardness of slide fastener also will increase.Under zip-tie is combined in situation in the clothes, expects vertical hardness and unlike significantly changing the outward appearance of clothes, or make its purposes or comfortableness is more restricted or reduce so remarkable.
Change
Although two kinds of heteroid positive profiles and cloudy profile have been described, yet should understand, many differences and preferred complementary shape also can be used for described positive profile and cloudy profile, this depends on the degree of the either side that puts on the slide fastener fastener when power needed tensile strength when unziping fastener, and the elasticity of slide fastener fastener and outline portion thereof is to adapt to the bending or the deflection of horizontal slide fastener fastener main shaft.For example when the longitudinal axis with slide fastener draws with meeting at right angles or pushes away fabric, or the parts of slide fastener fastener by sliding part with in conjunction with or break away from combination.Design feature of sun profile and the geomery of cloudy profile, employed material (as employed plastic type etc.) and the mode that forms outline portion are by injection molding or extruding or some other methods, can change via different application, output or for the different designs of specific purpose to the slide fastener fastener.
By using different qualities or material to be used for positive profile and cloudy profile and different flanges being arranged or by outline portion being installed to different bands, one side of slide fastener can be suitable for being installed to hard fabric, coarse drill cloth for example, the opposite side of slide fastener can be installed to extensile fabric simultaneously, for example lycra or neoprene.
Although in main example, mentioned and used plastic material to be used for different outline portions, yet equally probablely be, outline portion can be formed by neoprene or similar substance etc., and can form in the elastic webbing molded about, described elastic webbing can preferably have the stretching, extension feature with the stretching, extension feature similarity of the fabric that it is installed.For example, if the slide fastener fastener is installed on the lycra clothes, so preferably, the band of slide fastener fastener of the present invention forms part and also can be formed by the lycra with stretching, extension feature identical or less with the stretching, extension feature of the fabric that it is installed.In some cases, can expect to use such band: it has than the extensibility of the fabric that it is installed extensibility greatly, this is because various positive profiles and cloudy profile or their molded in segments can be caused the sclerosis a little of whole slide fastener fastener to described band, can make them return to the range of extension identical with the fabric that they are installed.
Although mentioned polyethylene and polyvinyl chloride as the preferred plastic material that is used for sun and cloudy profile, can use various other plastic materials yet should understand, this depends on application, for example described parts can by nylon, poly-tetrem alkene (PDFE) (polytetraethylene), low density polyethylene (LDPE) (LDPE), high density polyethylene (HDPE) (HDPE) and various other industrial plastic form.
Although preferably by independent section is injection molded into the slide fastener that a collection of band is made extensile optional segmentation, yet possible is, the elastoplast or the elastomeric material that also might be used for positive profile and cloudy profile by use are crushed to extensile slide fastener by extruding or mixing.
Although as a rule, sliding part is made by hard plastics, yet also might use other material, and metal is especially made all parts or the part of sliding part.Sliding part of the present invention generally has than the more shallow entrance angle of traditional sliding part that is used in tooth-like slide fastener, and tooth must be engaged with each other together in traditional sliding part.
At last, should be understood that and to carry out various other variation or changes to the aforementioned techniques scheme, and do not depart from the scope of the present invention.
