Description

Anordning ved stående fiskegarn. Device for standing fishing nets.

Ved de vanlige stående garn er kavlsnoren og bundsnoren like lange, slik at garnets endekanter danner omtrent rette vinkler med garnets lengderetning. Selv ved bruk av temmelig tunge hjørnesteiner festet til garnets nedre hjørner vil garnets nedre parti, særlig i sterk strøm og ved dype garn, bues fremover og oppover, idet hjørnesteinene trekkes mot hverandre, slik at bundsnoren ofte kan trekkes inn flere meter. Som følge av den stilling garnet derfor kan innta i sjøen, vil fisken lett kunne gå under garnet og unnslippe. In the case of the usual standing yarns, the winding cord and the bottom cord are of the same length, so that the end edges of the yarn form approximately right angles with the lengthwise direction of the yarn. Even when using fairly heavy cornerstones attached to the lower corners of the net, the lower part of the net, especially in strong currents and with deep nets, will curve forward and upwards, as the corner stones are pulled towards each other, so that the bottom line can often be pulled in several metres. As a result of the position the net can therefore take in the sea, the fish will easily be able to go under the net and escape.

Det er oppfinnelsens hensikt å bort-skaffe denne feil, og dette søkes oppnådd ved innkortning av bundsnoren i forhold til kavlsnoren, slik at garnets endekanter bringes til å skråne innover mot bundsnorens ender, hvortil hjørnesteinene er festet. En slik innkortet bundsnor vil holde seg strammere og minske strekket i kavlsnoren. Denne kan da gis litt slak, og strøm-men vil da gi garnet en meget gunstig stilling, idet garnets øvre parti vil bli buet fremover og litt nedover, mens den stram-me bundsnor vil hindre at garnets nedre parti bues vesentlig fremover. En fisk som kommer med strømmen iog stølter mot garnet vil alltid søke nedover, men på grunn av garnets skråstilling vil den van-skelig gå klar av dette. Et garn som er laget i overensstemmelse med oppfinnelsen vil derfor utvilsomt ha en betydelig forbedret fiskeevne. It is the purpose of the invention to eliminate this error, and this is achieved by shortening the bottom cord in relation to the coil cord, so that the end edges of the yarn are brought to slope inwards towards the ends of the bottom cord, to which the cornerstones are attached. Such a shortened bottom line will stay tighter and reduce the stretch in the furling line. This can then be given a little slack, and current will then give the yarn a very favorable position, as the upper part of the yarn will be bent forward and slightly downwards, while the tight bottom cord will prevent the lower part of the yarn from bending forward significantly. A fish that comes with the current and stumbles against the net will always search downwards, but due to the inclined position of the net, it will have difficulty clearing this. A net made in accordance with the invention will therefore undoubtedly have a significantly improved fishing ability.

Garnet fremstilles slik at dets endekanter ved innfelt garn, enten under fabri-kasjonen, ved beklipping eller på annen måte skråner innover fra kavlsnorens ender ned til bundsnorens ender og danner spisse vinkler med garnets overkant. Skrålinjene følger fortrinnsvis gangen i garnmaskene og danner således teoretisk vinkler på 45° med garnets overkant. The yarn is produced in such a way that its end edges in the case of embedded yarn, either during manufacture, by trimming or in some other way, slope inwards from the ends of the winding cord down to the ends of the bottom cord and form sharp angles with the upper edge of the yarn. The diagonal lines preferably follow the course of the yarn stitches and thus theoretically form angles of 45° with the upper edge of the yarn.

Oppfinnelsen vil bli nærmere forklart The invention will be explained in more detail

i forbindelse med tegningen, hvor: in connection with the drawing, where:

Fig. 1 viser skjematisk et uinnfelt og et innfelt garn fremstilt overensstemmende med oppfinnelsen. Fig. 2 viser skjematisk stillingen av et normalt garn i strømstille og i strømmende vann. Fig. 1 schematically shows an unset and a set yarn manufactured in accordance with the invention. Fig. 2 schematically shows the position of a normal net in still and flowing water.

Fig. 3 viser garnet i fig. 2 i snitt. Fig. 3 shows the yarn in fig. 2 on average.

Fig. 4 viser et garn ifølge oppfinnelsen, Fig. 4 shows a yarn according to the invention,

som vist i fig. 1. i strømmende vann. as shown in fig. 1. in flowing water.

I fig. 1 er vist et uinnfelt garn med dybde «D», overkant 1 og underkant 2. Garnets endekanter 3 følger gangen i garnmaskene 4, og endekantenes skrålinjer 3 danner da en vinkel «V» på 45° med garnets lengderetning. Ved innfelling av garnet kan skrålinjene 3 danne en noe steilere vinkel V. avhengig av innfellingsgraden. I samme figur er også garnet inntegnet i tykkere linjer og i innfelt tilstand, idet inn-fellingen i dette eksempel er valgt som 14 del, såvel på kavlsnoren 1' som på bundsnoren 2' og på endekantene 3', hvorved garndybden reduseres til «D'» = % D. In fig. 1 shows an unset yarn with depth "D", upper edge 1 and lower edge 2. The end edges 3 of the yarn follow the course of the yarn stitches 4, and the slant lines 3 of the end edges then form an angle "V" of 45° with the longitudinal direction of the yarn. When folding in the yarn, the inclined lines 3 can form a somewhat steeper angle V. depending on the degree of folding. In the same figure, the yarn is also drawn in thicker lines and in a set-in state, as the set-in in this example is chosen as 14 parts, both on the coil cord 1' and on the bottom cord 2' and on the end edges 3', whereby the yarn depth is reduced to "D '» = %D.

Fig. 2 viser i fullt opptrukne linjer et vanlig stående garn 5, hvis endekanter danner rette vinkler «R» med kavlsnoren 1, som er utspent med landfestesnor 8 og bøye 9 med festesnor 10 til ilesteinen. Garnets nedre hjørner er festet til hjørnestei-ner 7. Når dette garn utsettes for sterk strøm, og særlig hvis garnet er dypt, vil hjørnesteinene 7 bli trukket i retning mot hverandre og fremover i strømretningen til en stilling som vist ved 7'. Garnets endekanter skråner da innover til stilling 6' og danner spisse vinkler «S» med kavlsnoren. Bundsnoren bues fremover og oppover på grunn av strømmen, som vist ved stillingen 2-. Hele garnet inntar da den stilling som er vist i fig. 3, som er et snitt etter linjen I—I i fig. 2. Garnets midtparti 11 står her som en bue fremover og med bundsnoren 2<2> buet høyt oppover. Denne stilling blir vanligvis motarbeidet ved an-bringelse av belastning langs bundsnoren. Ved etterfølgende strømstille vil garnets midtparti stå tungt i vannet og henge ned som antydet ved den buete linje 23 i fig. 2. Fig. 2 shows in solid lines an ordinary standing net 5, the end edges of which form right angles "R" with the furling line 1, which is stretched out with a shore mooring line 8 and a buoy 9 with a mooring line 10 to the ilestone. The yarn's lower corners are attached to cornerstones 7. When this yarn is exposed to a strong current, and especially if the yarn is deep, the cornerstones 7 will be pulled towards each other and forward in the direction of the current to a position as shown at 7'. The end edges of the yarn then slope inwards to position 6' and form sharp angles "S" with the winding cord. The bottom line bends forwards and upwards due to the current, as shown at position 2-. The entire yarn then takes the position shown in fig. 3, which is a section along the line I—I in fig. 2. The middle part of the yarn 11 stands here like an arch forward and with the bottom cord 2<2> arched high up. This position is usually counteracted by applying a load along the bottom line. In the event of a subsequent blackout, the middle part of the yarn will stand heavily in the water and hang down as indicated by the curved line 23 in fig. 2.

For å motarbeide virkningen av strøm-men ved disse vanlige garn kan man på midtpartiet belaste bundsnoren med flere steiner, men dette har den svakhet at hele garnets innfelling vil gå ut, og særlig garnets midtparti vil stå stramt. In order to counteract the effect of current - but with these ordinary nets, you can load the bottom cord with several stones on the middle part, but this has the weakness that the whole netting of the net will come out, and especially the middle part of the net will be tight.

Ved stående garn av den konstruksjon som oppfinnelsen omhandler, med innover skrånende endekanter 3', hvorved bundsnoren er gjort kortere enn kavlsnoren, som vist i fig. 1, og med tilstrekkelig tunge hjørnesteiner festet til de nedre hjørner 14, 15, og med kavlsnoren utspent mellom landfeste og flytebøyen, festet henholdsvis til de øvre garnhjørner 12 og 13, vil garnet i strøm innta den stilling som er vist i fig. In the case of standing yarn of the construction to which the invention relates, with inwardly sloping end edges 3', whereby the bottom cord is made shorter than the coil cord, as shown in fig. 1, and with sufficiently heavy cornerstones attached to the lower corners 14, 15, and with the furling line stretched between the mooring and the buoy, attached respectively to the upper net corners 12 and 13, the net in current will assume the position shown in fig.

4. Bundsnoren holdes her praktisk talt stram, fordi hjørnesteinene ikke har noen tendens til å trekkes mot hverandre på grunn av endekantenes 3' skrå forbindelse 4. The bottom cord is kept practically taut here, because the cornerstones have no tendency to pull towards each other due to the 3' slanted connection of the end edges

med kavlsnorens ender 12, 13. Ved passende slakking av kavlsnoren vil garnet innta den gunstige stilling som er vist i snitt i fig. 4. with the winding cord's ends 12, 13. By suitably slackening the winding cord, the yarn will assume the favorable position shown in section in fig. 4.

Når man sammenlikner garnstilling-ene i fig. 3 og 4 ser man tydelig at en fisk som kommer med strømmen i pilens retning vil ha store sjanser til å komme under garnet i fig. 3, mens den derimot etter all sansynlighet vaser seg inn i garnets nedre del, når den forsøker å svømme nedover langs garnet i fig. 4. When comparing the yarn positions in fig. 3 and 4 you can clearly see that a fish coming with the current in the direction of the arrow will have a great chance of getting under the net in fig. 3, while, on the other hand, in all likelihood, it becomes embedded in the lower part of the yarn, when it tries to swim downwards along the yarn in fig. 4.
