Opfindelsen omhandler en lynlås med vævede bærebånd og i disse indvævede låseled af formstofmonofilament-tråde og af den i krav l's indledning angivne art, der er kendt fra beskrivelsen til tysk patent nr. 2 051 416, 5 hvor låseleddene er overgrebet eller undergrebet af en og samme bindekædetråd.The invention relates to a zipper with woven carrying straps and in these interwoven locking joints of plastic monofilament threads and of the kind set forth in the preamble of claim 1, which is known from the description of German Patent No. 2,051,416, wherein the locking joints are abrased or interrupted by one and the same. same binder chain thread.

Et problem med sådanne lynlåse er deres bøjningsstyrke, hvorved man forstår tværkraftsbrudstyrken ved udbøjning af lynlåsen ud fra dennes plan.~Som bekendt aftager 10 bøjningsstyrken mere eller mindre parabel formet med krumningsradien i området ved bøjningsvinklen, dvs., at jo mindre bøjningsvinklen er, desto mindre er bøjningsstyrken. Desuden skal delingsmålet være stabilt, da en forandring under vask eller rensning virker tilbage 15 på bøjningsstyrken og svækker denne.One problem with such zippers is their flexural strength, which is to understand the tensile strength of bending when deflecting the zipper from its plane. ~ As is well known, the bending strength decreases more or less parabularly shaped with the radius of curvature in the region of the bending angle, i.e., the smaller the bending angle, the more less is the bending strength. In addition, the splitting target must be stable as a change during washing or purification acts back on the bending strength and weakens it.

Opfindelsen har til formål at tilvejebringe en lynlås af den angivne art med en forbedret bøjningsstyrke og med en forbedring af delingsmål-stabiliteten.The invention has for its object to provide a zipper of the specified type with an improved bending strength and with an improvement of the split target stability.

Dette opnås ifølge opfindelsen ved en kombineret udform-20 ning af lynlåsen som angivet i krav l's kendetegnende del, hvor bøjningsstyrken forbedres ved en afstivende polstring imellem låseleddenes øverste grene, idet polstringen nedsætter den ved bestemte bøjningskræfter optrædende krumning og altså forhindrer, at der opstår 25 en for lille krumningsradius ved bøjningsstedet, og hvor desuden delingsmålet er stabiliseret.This is achieved according to the invention by a combined design of the zipper as claimed in the characterizing part of claim 1, wherein the bending strength is improved by a stiffening padding between the upper branches of the locking joints, the padding reducing the curvature occurring at certain bending forces and thus preventing a radius of curvature too small at the point of bending, and in addition the target of stabilization.

Opfindelsen forklares nærmere nedenfor i forbindelse med tegningen, hvor: fig. 1 viser et bindingsskema for en lynlås ifølge op-30 findelsen,The invention is further explained below in connection with the drawing, in which: FIG. 1 shows a zipper binding scheme according to the invention,

3 skudtråd 6. Låseledrækkerne 7 omfatter hver især i form af et formstofmonofilament-dobbeltskud indførte låseled 2 med set i retningen mod lynlåsplanet i det væsentlige over hinanden liggende grene 8 og 9, nemlig en underste 5 gren 8 og en øverste gren 9, samt låsehoveder 10 og bagud vendende forbindelsesdele 11. Låseleddene 2 overgribes af bindekædetråde 12 og er dermed forenet med bærebåndet 1. Dobbeltskuddene 4 og 5 af grundskudtrådene 6 er dels anbragt i området imellem låseleddene 2 og 10 dels anbragt under disse i særskilte grundkædetrådslom- mer 13 i et under låseleddene liggende bærebåndsområde.3 shooting wires 6. The locking lugs 7 each comprise locking lugs 2 inserted in the form of a plastic monofilament double-shot, in the direction towards the zipper plane, substantially opposite branches 8 and 9, namely a lower 5 branch 8 and a upper branch 9, as well as locking heads. 10 and rearwardly connecting portions 11. The locking joints 2 are gripped by the link chain wires 12 and are thus joined to the carrier belt 1. The double pads 4 and 5 of the base wires 6 are partly located in the region between the locking joints 2 and 10 and partly located below these in separate ground chain wires 13. under the locking joints.

Som vist på fig. 1 og 6 overgriber bindekædetrådene 12 to låseled 2 med undergribning af det derimellem anbragte grundskudtråds-dobbeltskud 5. Det ses også, 15 at bindekædetrådene 12 er forsat et trin i lynlåsens længderetning. For tydeligheds skyld er de forsatte kædetråde 12 vist med hver sin linieart. Et følgende låseled 2 undergribes imellem sin underste gren 8 og de derunder anbragte grundskudtråds-dobbeltskud 4. Der-20 efter indbindes bindekædetrådene 12 i det under låseled dene 2 beliggende bærebåndsområde. Endvidere fremgår det af fig. 1 og 6, at grundskudtråd-dobbeltskuddet 5 imellem låseleddene 2 er trukket op til eller over højden af den øverste låseledsgren 9 ved mindst én af 25 bindekædetrådene 12 som en grundskudtrådsafstivnings strop 14. Hvad der forstås derved ses også ved en sammenlignende betragtning af fig. 2-5, henholdsvis fig.As shown in FIG. 1 and 6, the tie chain threads 12 cross two locking joints 2 with the intersection of the base shot double-shot 5 disposed therebetween. It is also seen that the tie chain threads 12 are staggered one step in the longitudinal direction of the zipper. For the sake of clarity, the offset warp threads 12 are shown with their respective line types. A subsequent locking link 2 is interrupted between its lower branch 8 and the grounding double-shot threads placed below it. Thereafter, the binder chain threads 12 are tied into the carrier belt area located below the locking link 2. Furthermore, it can be seen from FIG. 1 and 6, that the base shot wire double shot 5 between the locking joints 2 is pulled up to or above the height of the upper locking joint 9 by at least one of the 25 tie chain wires 12 as a grounding wire stiffening strap 14. What is understood is also seen in a comparative view of FIG. 2-5, respectively.

7 - 10. Fig. 5 og 10 viser, at afstivningsstropperne 14 danner en slags polstring imellem de øverste grene 30 9 af to nabolåseled 2. Endvidere kan en eller flere grundkædetråde 3 imellem to nabolåseled 2 trækkes op til eller over højden af de øverste låseledsgrene som grundkædetrådsafstivningsstropper 15 som vist på fig.7 - 10. FIG. 5 and 10 show that the stiffening straps 14 form a kind of padding between the upper branches 30 9 of two neighboring joints 2. Furthermore, one or more ground chain threads 3 between two neighboring joints 2 can be pulled up to or above the height of the top locking joints as the basic chain threading straps 15 as shown. FIG.

6 og 7 - 10. I den på fig. 1-5 viste udførelsesform 35 er indbindingen af bindekædetrådene 12 udført således, at det under låseleddene 2 beliggende bærebåndsområde6 and 7 - 10. In the embodiment of FIG. 1-5, the binding of the link chain wires 12 is made such that the carrier area located below the locking links 2

4 undergriber to grundskudstråds-dobbeltskud 4 og 5, nemlig skuddet 5 i området imellem to nabolåseled 2 og skuddet 4 under låseleddene 2. Den på fig. 6-10 viste udførelsesform er ændret lidt i forhold hertil, idet 5 bindekædetrådene 12 ved indbindingen i det under låse leddene 2 beliggende bærebåndsområde undergriber det imellem to nabolåseled 2 beliggende grundskudtråds-dob-beltskud 5, derefter føres imellem den underste gren 8 af det næste låseled 2 og det derunder liggende grund-10 skudtråds-dobbeltskud 4 og til overgribning af de næste to låseled 2. Fig. 5 og 10 viser en foretrukken udførelsesform for opfindelsen, hvor grundskudtrådsafstivningsstropperne 14 og/eller grundkædetrådsafstivningsstropper-ne 15 i sammenlåst stand af låseleddene 2 udfylder rummet 15 imellem to øverste nabogrene 9 af låseleddene 2 og det indlåste låsehoved 10 som en polstring, så at låsefladerne ligger an imod hinanden som med en forspænding.4 interferes with two basic shot-wire double shoots 4 and 5, namely the shot 5 in the region between two neighboring joints 2 and the shot 4 below the locking joints 2. The one shown in FIG. 6-10 are slightly modified in relation thereto, by tying in the carrier belt area located below the locking joints 2, the binder chain threads 12 interferes with the base shoot thread double shoots located between two neighboring joints 2, then passes between the lower branch 8 of the next locking link 2 and the underlying base shot double-shot 4 and for gripping the next two locking links 2. FIG. Figures 5 and 10 show a preferred embodiment of the invention, in which the grounding thread stiffening straps 14 and / or the ground chain threading straps 15 in the locked position of the locking joints 2 fill the space 15 between two upper neighboring arms 9 of the locking joints 2 and the locked locking head 10 as locking head 10. against each other as with a bias.

Den på fig. 11 og 12 viste lynlås omfatter vævede bære-bånd 1 og i disse indvævede, under vævningen dannede 20 låseledrækker 7 af formstofmonofilamenttråde. For tyde lighedens skyld er grundskudtrådene 6 i bærebåndet 1 tegnet overdrevent tykke og i modsætning hertil grund-kædetrådene 3 i bærebåndet 1 tegnet overdrevent tynde som enkelte streger. På snitfiguren 12 er bindekædetrå-25 dene 12 vist med forskellige liniearter. Ligesom i den på fig. 1-10 viste udførelses form er bærebåndene 1 opbygget af kædetrådene 3 og 12 og ved siden af hinanden liggende dobbeltskud 4 og 5 af en kontinuert forløbende grundskudtråd 6. Låseledrækkerne 7 er hver især udformede 30 som et skruelinieformet formstofmonofilament-dobbeltskud med set i retning mod lynlåsens plan mere eller mindre over hinanden liggende grene 8 og 9 af de enkelte låseled 2 med låsehoveder 10 og bagud vendende forbindelsesdele 11. Grundskudtrådene 6 er ført som dobbeltskud 35 hen til låsehovederne 10 af låseleddene 2, hvilke låse-The FIG. 11 and 12, zippers comprise woven carriers 1 and in these interwoven, 20 interlocking fabrics 7 formed of monofilament yarns formed during the weaving. For the sake of similarity, the grounding strands 6 in the carrier 1 are drawn excessively thick and, in contrast, the basic warp threads 3 in the carrier 1, are drawn excessively thin as single lines. On the cut figure 12, the binder chain threads 12 are shown with different linear species. As in the FIG. 1 to 10, the straps 1 are formed by the warp threads 3 and 12, and adjacent double shoots 4 and 5 of a continuous extending base shoot thread 6. The locking lugs 7 are each shaped 30 as a helical plastic monofilament double shoot with a view towards the plane of the zipper more or less superposed on branches 8 and 9 of the individual locking joints 2 with locking heads 10 and rearwardly connecting parts 11. The basic pushing wires 6 are guided as double shoots 35 to the locking heads 10 of the locking joints 2 which

5 hoveder naturligvis ligger frit. Låseleddene 2 overgribes skiftevis af bindekædetrådene 12, som skiftevis undergriber dobbeltskuddene af grundskudtrådene 6 til forening af låseledrækkerne 7 med det tilhørende bærebånd 1.5 heads are of course free. The locking joints 2 are alternately gripped by the tie chain wires 12, which alternately interferes with the double shoots of the basic weft threads 6 for joining the locking lugs 7 with the associated carrying strap 1.

5 Anordningen er således, at hvert andet dobbeltskud 4 af grundskudtrådene 6 er anbragt under låseleddene 2 og de mellemliggende dobbeltskud 5 imellem låseleddene 2 i særskilte grundkædetrådslommer 13. Bærebåndene 1 har i området af låseleddene 2 et i lynlåsens længde-10 retning forløbende bærebåndsafsnit 16 af grundskudtråds- dobbeltskuddene 4 og 5 og grundkædetrådene 3. Af delingsmålsmæssige grunde er dobbeltskuddene 4 og 5 dels anbragt under låseleddene 2 og dels anbragt imellem disse. Bindekædetrådene 12, som danner forbindelsen af låseledde-15 ne 2 med bærebåndene 1, er ført skiftevis på en særskilt måde, der fremgår af fig. 12. Det ses, at der er anbragt over bærebåndets plan forløbende, to skudindføringer forsatte bindekædetråde 12, som i hver på hinanden følgende forbindelse skiftevis overgriber et låseledspar 20 2 og et følgende låseled 2 og undergriber det næste låseled 2, osv. Desuden er anordningen således, at hver bindekædetråd 12 undergriber grundskudtråds-dobbelt-skuddet 5 imellem det fælles overgribende låseledspar og det følgende låseled 2. Bindekædetrådene 12 under-25 griber desuden grundskudstråds-dobbeltskuddet 5 imellem det enkelte overgrebne og det følgende undergrebne låseled 2. På fig. 11 og 12 er der vist fire på den omtalte måde førte bindekædetråde 12, men der kan også anvendes flere eller færre bindekædetråde, og desuden kan man 30 også sammenfatte ens førte bindekædetråde i grupper.5 The device is such that every other double shot 4 of the base shoot threads 6 is placed under the locking joints 2 and the intermediate double shoots 5 between the locking joints 2 in separate ground warp pockets 13. The straps 1 have in the region of the locking joints 2 a carrier section extending in the longitudinal direction 10 of the lock. The base shoots double shoots 4 and 5 and the ground chain threads 3. For reasons of division, the double shoots 4 and 5 are placed partly under the locking joints 2 and partly between them. The tie chain wires 12 forming the connection of the locking joints 2 with the straps 1 are alternately guided in a separate manner as shown in FIG. 12. It is seen that, along the plane of the carrier, there are arranged two tapered insertions of connecting chain threads 12, which in each successive connection alternately engage a locking pair 20 2 and a subsequent locking link 2 and interrupting the next locking link 2, etc. In addition, the device is so that each binder chain thread 12 interferes with the base shot wire double shot 5 between the common overall locking link pair and the following locking link 2. The binder chain wires 12 also interrupt the base shot wire double shot 5 between the single abused and the subsequent interlocked locking link 2. 11 and 12, four binder chain threads 12 are shown in the aforementioned manner, but more or less binder chain threads can also be used, and in addition, one can also bind one's binder chain threads in groups.
