Description

Opfindelsen omhandler et lynlåsbånd af den i krav l's indledning angivne art'.The invention relates to a zipper strap of the type specified in the preamble of claim 1 '.

Fra tysk offentliggørelsesskrift nr. 2 219 907 kendes en 5 lynlås af denne art, hvor der for hver monofilamentsløj-fe kun er indført en enkelt grundskudtrådssløjfe i bærebåndet. De kædetrådsfagene dannende kædetråde overgriber kun et enkelt låseled og dermed en enkelt grundskudtrådssløjfe. Herved tilvejebringes der nok en forholds-10 vis fast forbindelse mellem låseledrækken og bærebåndet, ~ men alligevel er delingsstabiliteten ret dårlig, fordi bærebåndet er vævet forholdsvis løst med kun én grundskudtrådssløjfe per låseled. Dette forøger risikoen for oprivning af den af to lynlåsbånd sammensatte lynlås ved 15 dennes bøjningspåvirkninger i og ud af lynlåsplanet.German Offenlegungsschrift No. 2,219,907 discloses a zipper of this kind, in which only a single base weft loop is inserted in the carrier tape for each monofilament loop. The warp threads forming the warp threads span only a single locking joint and thus a single base weft loop. This probably provides a relatively fixed connection between the locking pull and the carrying strap, but still the division stability is rather poor because the carrying strap is woven relatively loosely with only one base weft thread loop per locking joint. This increases the risk of tearing the zipper composed of two zipper bands by its bending effects in and out of the zipper plane.

Fra engelsk patentskrift nr. 1 305 490 kendes et lynlåsbånd af samme art, hvor der er anbragt dobbeltskudtråde både under hver monofilamentsløjfe og midt imellem hver 20 af disse sløjfer, men således, at bærebåndspartiet i lå-seledrækkeområdet opdeles i to dele, beliggende henholdsvis under og over låseledrækken, som hermed kommer til at ligge mellem to "flanger" og bliver temmelig stiv.From British Patent Specification No. 1 305 490 a zipper strap of the same kind is known, in which double weft threads are arranged both below each monofilament loop and in the middle between each of these loops, but in such a way that the carrying strap portion in the locking strap area is divided into two parts, located below and over the locking pull, which hereby lies between two "flanges" and becomes rather stiff.

Opfindelsen har til formål at tilvejebringe et lynlåsbånd af den angivne art med en bindingsudformning, der stabiliserer delingsmålet, dvs. afstanden mellem to na-bolåseled, så denne forbliver konstant og uændret ved 30 almindelig brug, herunder rensning og vask, alt imens lynlåsen stadig er blød og fleksibel, som krævet af beklædningsindustrien.The object of the invention is to provide a zipper strap of the type indicated with a binding design which stabilizes the dividing target, i.e. the distance between two na-bol locks so that it remains constant and unchanged during normal use, including cleaning and washing, all the while the zipper is still soft and flexible, as required by the clothing industry.

Dette opnås ifølge opfindelsen ved en udformning af den 35This is achieved according to the invention by a design of the 35

Det stabiliserede delingsmål bidrager også til at forøge lynlåsens oprivningssikkerhed ved kraftpåvirkninger ud fra lynlåsplanet.The stabilized division target also helps to increase the tear-off safety of the zipper in the event of force effects from the zipper plane.

10 Opfindelsen beskrives nærmere nedenfor i forbindelse med tegningen, hvor: fig. 1 er en plan af lynlåsbåndet ifølge opfindelsen, 15 fig. 2 er en afbildning af lynlåsbåndet på fig. 1, set i pilretningen A, fig. 3 er et længdesnit igennem lynlåsbåndet på fig. 1 langs linien B-B, og 20 fig. 4-6 viser tre andre udførelsesformer for lynlåsbåndet på fig. 3.The invention is described in more detail below in connection with the drawing, in which: fig. 1 is a plan view of the zipper strap according to the invention, FIG. 2 is a view of the zipper strap of FIG. 1, seen in the direction of the arrow A, fig. 3 is a longitudinal section through the zipper band of FIG. 1 along the line B-B, and fig. 4-6 show three other embodiments of the zipper strap of fig. 3.

Den på fig. 1-6 viste udførelsesform for lynlåsbåndet 25 ifølge opfindelsen har et vævet bærebånd 1 og en deri indvævet, under væveoperationen dannet lynlåseledrække 2 af en formstofmonofilamenttråd. Af illustrationsmæssige grunde er bærebåndets grundskudtråd 3 vist stærkt fortykket og bærebåndets kædetråde 4, 5, 6 og 7 vist stærkt 30 fortyndede. Det ses, at bærebåndet 1 er opbygget af kædetrådene 4-7 og ved siden af hinanden liggende sløjfer 8 af en kontinuerlig grundskudtråd 3, og at låseledræk-ker 2 er udført som en skruelinieformet formstofmonofi-lamentsløjfe og med, set i retning mod lynlåsplanet, me-35The one in fig. 1-6, the zipper strap 25 according to the invention has a woven carrying strap 1 and a zipper liner 2 formed of a plastic monofilament thread formed therein during the weaving operation. For illustrative purposes, the base weft thread 3 of the carrier tape is shown to be greatly thickened and the warp threads 4, 5, 6 and 7 of the carrier tape are shown to be greatly thinned. It can be seen that the carrying strap 1 is built up of the warp threads 4-7 and adjacent loops 8 of a continuous base weft thread 3, and that locking guide racks 2 are designed as a helical plastic monofilament loop and with, seen in the direction of the zipper plane, me-35

3 re eller mindre over hinanden liggende grene 9 af de enkelte sløjfer 10, låséhoveder 11 og bagtil liggende forbindelsesbroer 12. Grundskudtråden 3 er ført som sløjferne 8 til låsehovederne 11, der naturligvis ligger 5 frit. Monofilamentsløjferne 10 er overgrebet af kædetrådene 4-7 til forbindelse af låseledrækken 2 med dennes tilhørende bærebånd 1. Anordningen er således, at hver anden sløjfe 8 af grundskudtråden 3 ligger under monofilament sløj ferne 10 i særskilte bærebåndskædetrådsfag 13.3 re or less superimposed branches 9 of the individual loops 10, locking heads 11 and rear connecting bridges 12. The weft wire 3 is guided as the loops 8 to the locking heads 11, which of course lie 5 freely. The monofilament loops 10 are gripped by the warp threads 4-7 for connecting the locking drawer 2 with its associated carrying strap 1. The arrangement is such that every other loop 8 of the base weft thread 3 lies below the monofilament loops 10 in separate carrying strap warp threads 13.

10 Af kædetrådene 4-7 i disse bærebåndskædetrådsfag 13 er i det mindste nogle ført ud fra bærebåndsplanet og over grenene 9 af låseleddene 10, som nærmere vist på fig. 3- 6. Det ses, at disse kædetråde 4-7 danner forbindelseskædetrådsfag 14 for monofilamentsløjferne 10, hvilke fag 15 14 ligger i en særskilt etage over bærebåndsplanet.Of the warp threads 4-7 in these carrier tape warp thread sections 13, at least some are led out from the carrier belt plane and over the branches 9 of the locking joints 10, as shown in more detail in fig. 3.

Det kan forstås uden videre, at grundskudtråden 3 kan forskydes tilstrækkeligt i forhold til låseledrækken 2 ved bøjningspåvirkninger i og ud fra lynlåsplanet i til-20 strækkelig grad til at undgå forstyrrende tvangskræfter, idet dog delingsstabiliteten er opnået ved, at der imellem hver monofilamentsløjfe 10 er en tilstrækkelig mængde af krydsende kædetråde 4-7, hvis antal, tykkelse og spænding kan regulere og fiksere delingsmålet uden ind-25 flydelse på blødheden og bøjeligheden.It can be readily understood that the weft thread 3 can be displaced sufficiently relative to the locking drawer 2 by bending influences in and out of the zipper plane to a sufficient degree to avoid disturbing coercive forces, yet the division stability is obtained by between each monofilament loop 10 a sufficient amount of intersecting warp threads 4-7, the number, thickness and tension of which can regulate and fix the division target without affecting the softness and flexibility.

Imellem sløjferne 8 af grundskudtråden 3, som ligger under monofilamentsløjferne 10, er der i udførelseseksemplet yderligere sløjfer 8a af grundskudtråden 3, belig-30 gende omtrent midt imellem to hosliggende sløjfer 10. I den på fig. 3 viste udførelsesform er anordningen således, at to på hinanden følgende sløjfer 8, 8a af grundskudtråden 3 forløber sammenhørende i et kædetrådsfag 13, medens hver monofilamentsløjfe 10 ligger i et kæde-35Between the loops 8 of the base weft thread 3, which lies below the monofilament loops 10, in the exemplary embodiment there are further loops 8a of the base weft thread 3, located approximately midway between two adjacent loops 10. In the embodiment shown in fig. 3, the arrangement is such that two successive loops 8, 8a of the base weft thread 3 run concurrently in a warp thread compartment 13, while each monofilament loop 10 lies in a warp-35

4 trådsfag 14, hvis kædetråde 4-7, forsat i lynlåsens længderetning, overgri'ber to på hinanden følgende mono-filamentsløjfer. Som vist på fig. 5 og 6 kan anordningen også være således, at nogle af bærebåndets kædetråde 15, 5 også i området ved monofilamentsløjferne 10, kun tilhører kædetrådsfaget 13.4 threads 14, whose warp threads 4-7, continued in the longitudinal direction of the zipper, overlap two successive mono-filament loops. As shown in FIG. 5 and 6, the device can also be such that some of the warp threads 15, 5 of the carrier tape, also in the area of the monofilament loops 10, only belong to the warp thread section 13.

Fig. 5 og 6 viser den foretrukne udførelsesform for lynlåsbåndet ifølge opfindelsen, der udviser særlig gunsti-10 ge bøjningsegenskaber af den færdige, i det hele bløde og bøjelige lynlås. I tilslutning til et kædetrådsfag 13 er kædetrådene 4-7 for en grundskudtrådssløjfe 8 ført ud fra bærebåndsplanet følgende efter hinanden i lynlåsens længderetning imellem to monofilamentsløjfer 10, deref-15 ter over og dækkende en eller flere monofilamentsløjfer 10 og mellem to monofilamentsløjfer 10 atter indført i bærebåndet 1, hvor de danner yderligere kædetrådsfag 13.FIG. 5 and 6 show the preferred embodiment of the zipper strap according to the invention, which exhibits particularly favorable bending properties of the finished, generally soft and flexible zipper. In connection with a warp thread section 13, the warp threads 4-7 of a base weft loop 8 are guided from the carrier band plane following one another in the longitudinal direction of the zipper between two monofilament loops 10, then over and covering one or more monofilament loops 10 and between two monofilament loops the conveyor belt 1, where they form additional warp threads 13.
