Den foreliggende opfindelse angår en fiskefileteringskniv med et knivsblad og et håndtag, hvor knivsbladet har en spids fri ende, hvorfra knivsbladets bredde tiltager i retning mod håndtaget, idet knivsbladets ægkant regnet fra spidsen først forløber konvekst og 5 svagt bueformet for derefter at overgå i en tilnærmelsesvis retli-niet del, og knivsbladets rygkant regnet fra spidsen først forløber konvekst og svagt bueformet for derefter at overgå i en tilnærmelsesvis retliniet del, hvor de tilnærmelsesvis retliniede dele danner en vinkel med hinanden, der ligger mellem 0 og 10*.The present invention relates to a fish filleting knife with a knife blade and a handle, the knife blade having a tip free end, from which the width of the knife blade increases in the direction of the handle, the edge of the knife blade, calculated from the tip, first extending convex and slightly arcuate, then passing into an approximate the rectilinear portion, and the ridge edge of the knife blade, calculated from the tip, first extends convex and slightly arcuate, and then passes into an approximately rectilinear portion, the approximately rectilinear portions forming an angle with one another ranging from 0 to 10 *.

Ved de kendte fiskefi leteringsknive af denne art forløber den tilnærmelsesvis retliniede del af knivsbladets rygkant stort set i forlængelse af håndtagets rygside. Den tilnærmelsesvis retliniede del af knivsbladets ægkant forløber på en sådan måde, at der kun 15 findes et meget lille frit mellemrum mellem en tænkt forlængelse af denne retliniede del og håndtagets fingergrebsside. Erfaringer har vist, at denne udformning har visse ulemper, idet det forholdsvis lille mellemrum mellem den tænkte forlængelse af knivsbladets retliniede ægkant og den tilsvarende side af håndtaget bevirker, at 20 operatøren let kommer til at gnide sine fingre og knoer mod underlaget, når fisken skal fileteres. Følgelig vil betjeningspersonen vippe sit håndled således, at betjeningspersonen primært skærer i fisken med den forreste del af knivsbladet, hvilket er ret anstrengende. Hertil kommer, at da knivsbladets rygkant forløber stort set 25 i flugt med håndtagets rygside, skal der for at foretage fri skæring af fileterne foretages ret store håndledsbevægelser.In the prior art fishing guide knives of this kind, the approximately rectilinear portion of the ridge edge of the knife blade extends substantially along the back side of the handle. The approximately rectilinear portion of the edge of the knife blade extends in such a way that there is only a very small free space between an imaginary extension of this rectilinear portion and the finger grip side of the handle. Experience has shown that this design has some drawbacks, since the relatively small gap between the thoughtful extension of the rectilinear edge of the knife blade and the corresponding side of the handle causes the operator to easily rub his fingers and knuckles against the ground when the fish is to filleted. Accordingly, the operator will tilt his wrist so that the operator primarily cuts the fish with the front of the knife blade, which is quite strenuous. In addition, since the back edge of the knife blade extends roughly 25 in alignment with the back side of the handle, in order to make free cutting of the fillets fairly large wrist movements must be made.

Det er formålet med den foreliggende opfindelse at anvise en fiskefileteringskniv af den indledningsvis nævnte art, ved hvilken disse 30 ulemper er reduceret eller undgået, og dette opnås ifølge opfindelsen ved, at knivsbladet har en sådan stilling i forhold til håndtaget, at der mellem en tænkt forlængelse af den tilnærmelsesvis retliniede del af knivsbladets ægkant og den hosværende sidekant af håndtaget findes et mellemrum, hvis bredde stort set svarer til 35 tykkelsen af en finger, samt at en tænkt forlængelse af den tilnærmelsesvis retliniede del af knivsbladets rygkant i det mindste ved håndtagets forende forløber inde i dette i afstand fra dets rygside.It is the object of the present invention to provide a fish filleting knife of the kind mentioned at the outset by which these disadvantages are reduced or avoided, and this is achieved according to the invention in that the knife blade has such a position relative to the handle that between extending the approximately rectilinear portion of the blade edge of the knife blade and the present side edge of the handle, there is a gap approximately the width of which corresponds to the thickness of a finger, and that a thoughtful extension of the approximately rectilinear portion of the blade edge backside is at least at the forward end of the handle extends inside this at a distance from its back.

Herved opnås det, at betjeningspersonen har mulighed for at arbejde med en forholdsvis lav knivsbladføring, d.v.s. med ægkantens stortHereby it is achieved that the operator has the opportunity to work with a relatively low blade blade, i.e. with the egg margin large

2 set retliniede del tilnærmelsesvis parallelt med underlaget, uden at de fingre eller knoerne på de fingre, der griber omkring håndtaget, kommer i berøring med underlaget, og samtidig bevirker den angivne forsætning af knivens rygkant i forhold til håndtagets rygside, at 5 blot små drejningsbevægelser i håndleddet vil bevirke forholdsvis store siderettede bevægelser af knivens ægkant, hvorved friskæringen af fiskefileter fra fiskenes rygben lettes, og dette er opnået, til trods for at bredden af knivsbladet til fileteringsknive i henhold til den foreliggende opfindelse ikke behøver at være formindsket i 10 forhold til bredden af de indledningsvis omtalte kendte fileteringsknive.2, the rectilinear portion is approximately parallel to the substrate, without the fingers or knuckles of the fingers gripping the handle contacting the substrate, and at the same time, the indicated displacement of the knife's back edge relative to the back of the handle causes 5 small pivotal movements in the wrist will cause relatively large lateral movements of the knife edge of the knife, thereby facilitating the cutting of fish fillets from the fish's back legs, and this is achieved, despite the fact that the width of the blade for filleting knives according to the present invention need not be reduced in relation to the width of the known filleting knives initially mentioned.

Opfindelsen skal herefter forklares nærmere under henvisning til tegningen, hvor 15 fig. 1 viser en udførelsesform for en fiskefi leteringskniv ifølge den foreliggende opfindelse, set fra siden, fig. 2 et snit efter linien II-II i fig. 1, og 20 fig. 3 et billede af den i fig. 1 viste kniv set fra oven.The invention will now be explained in more detail with reference to the drawing, in which FIG. 1 is a side elevational view of an embodiment of a fish-feeding knife according to the present invention; FIG. 2 is a sectional view taken along line II-II of FIG. 1, and FIG. 3 is a view of the embodiment of FIG. 1 from above.

På tegningen betegner 1 den viste fiskefi leteringsknivs knivsblad og 2 dens håndtag. Knivsbladet har tiltagende bredde regnet fra knivs-25 bladets frie spidse ende 3, idet knivsbladets ægkant 4 regnet fra spidsen 3 først forløber konvekst og svagt bueformet mellem spidsen 3 og et punkt 5 på ægkanten. Fra punktet 5 og ind til knivsbladets bredeste del 6 har ægkanten 4 stort set retliniet form, idet den del af ægkanten, der forløber fra punktet 5 og til den bredeste del, 30 udgør en stort set retliniet del 7. Knivsbladets rygkant 8 forløber regnet fra spidsen 3 først konvekst og svagt bueformet langs en del 9 og ind til et punkt 10, hvorefter der følger en stort set retliniet del 11. Oe to retliniede dele 7 og 11 danner en vinkel a med hinanden, der ved den på tegningen viste udførelsesform er ca. 4,5e.In the drawing, 1 represents the knife blade of the fishfishing knife shown and 2 represents its handle. The knife blade has increasing width, calculated from the free tip end 3 of the knife blade, the edge of the knife blade 4, calculated from the tip 3, first extending convex and slightly arcuate between the tip 3 and a point 5 on the edge of the egg. From point 5 to the widest part 6 of the knife blade, the edge of the egg 4 is substantially rectilinear, the part of the egg edge extending from the point 5 to the widest part 30 forming a substantially rectilinear part 7. The ridge edge 8 of the knife blade extends from the tip 3 is first convex and slightly arcuate along a portion 9 and into a point 10, followed by a substantially rectilinear portion 11. Oe two rectilinear portions 7 and 11 form an angle α with each other which, in the embodiment shown in the drawing, is ca. 4,5e.

35 Imidlertid kan denne vinkel ligge mellem 0 og 10e og hensigtsmæssigt mellem 3 og 6*.However, this angle may be between 0 and 10e and suitably between 3 and 6 *.

Som det fremgår af fig. 1, har knivsbladet 1 en sådan stilling i forhold til håndtaget 2, at der mellem en tænkt forlængelse 12 af 3As shown in FIG. 1, the blade 1 has such a position relative to the handle 2 that between a thought extension 12 of 3

DK 160683 BDK 160683 B

den tilnærmelsesvis retliniede del 7 af knivsbladet l's ægkant 4 og den mod denne forlængelse vendende sidekant eller fingergrebsside 14 af håndtaget 2 dannes et frit mellemrum 15, hvis bredde stort set svarer til tykkelsen af en finger. Endvidere fremgår det af fig. 1, at knivsbladets stilling i forhold til håndtaget er en sådan, at en tænkt forlængelse 16 af rygkantens retliniede del 11 strækker sig ind i håndtaget 2 ved dettes forreste ende (nærmest knivsbladet) og her forløber inde i håndtaget i afstand fra dettes rygside 17.the approximately rectilinear portion 7 of the cutting edge 1 of the knife blade 1 and the lateral or finger grip side 14 of the handle 2 of the handle 2 form a free space 15, the width of which corresponds substantially to the thickness of a finger. Furthermore, it can be seen from FIG. 1, the position of the knife blade relative to the handle is such that a thoughtful extension 16 of the rectilinear portion 11 of the ridge extends into the handle 2 at its front end (closest to the knife blade) and here extends inside the handle away from its back side 17.

I fig. 1 er der indtegnet vinkelhalveringslinien 18 for den vinkel a, som de retliniede dele 7 og 11 danner med hinanden. Af fig. 1 vil det ses, at denne vinkel halveringslinie 18 stort set tangerer fingergrebssiden 14 af håndtaget. Det vil forstås, at der med "fingergrebssiden" her skal forstås den side af håndtaget, der vender mod skærebrættet, når kniven anvendes, og som tjener til indgreb med betjeningspersonens fingre. Ved den på tegningen viste udførelsesform er denne fingergrebsside ved begge sine ender afgrænset af knaster, henholdsvis 20 og 21, for at lette betjeningspersonens fornemmelse af, hvorledes vedkommende griber kniven.In FIG. 1, the angular bisector line 18 is drawn for the angle α which the rectilinear portions 7 and 11 form with one another. In FIG. 1, it will be seen that this angle bisecting line 18 substantially tangles the finger grip side 14 of the handle. It will be understood that the "finger grip side" here means the side of the handle that faces the cutting board when the knife is used and which serves to engage the operator's fingers. In the embodiment shown in the drawing, this finger grip side at both its ends is bounded by knobs, 20 and 21, respectively, to facilitate the operator's sense of how to grip the knife.

I kraft af forløbet af den tænkte forlængelse 16 af den retliniede del 11 af rygkanten er knivsbladet med andre ord forsat i forhold til håndtaget, og det samme gælder det forklarede forløb af forlængelsen 12 af ægkantens retliniede del. Sagt med andre ord, svarer den på tegningen viste udførelsesform for fiskefi leteringskniven ifølge den foreliggende opfindelse til en kendt fileteringskniv, men hvor man må tænke sig knivsbladet friskåret i forhold til håndtaget og fastgjort til dette efter at være forsat ca. en trediedel af knivsbladets største bredde til den side, hvor ægkanten vender.In other words, by virtue of the course of the thought elongation 16 of the rectilinear portion 11 of the spine, the knife blade is continued with respect to the handle, and the same is true of the explained course of the extension 12 of the rectilinear portion of the egg. In other words, the embodiment of the fish filleting knife of the present invention shown in the drawing is similar to a known filleting knife, but where the knife blade is thought to be freshly cut relative to the handle and attached thereto after having been mounted for approx. a third of the blade's greatest width to the side where the edge of the egg is facing.

For at undgå en skarp overgang mellem håndtagets rygside 17 og knivsbladet er den forreste del af rygsiden 17 udformet skrå som vist ved 23.In order to avoid a sharp transition between the back side 17 of the handle and the knife blade, the front part of the back side 17 is inclined as shown at 23.

Mellem håndtagets forreste knast 20 og den bredeste del 6 af knivsbladet er der udformet en bugt 24 i dette, hvilket giver en passende afstand mellem en hånd, der griber omkring håndtaget, og den inderste del af bladets ægkant.Between the front cam 20 of the handle and the widest part 6 of the knife blade, a bay 24 is formed therein, providing a suitable distance between a hand gripping the handle and the innermost portion of the blade's egg edge.

Som det fremgår af fig. 2, er håndtagets rygside og fingergrebsside blødt afrundede, og endvidere er håndtaget gjort gribevenligt takket være en svag udbugtning 24 mellem knasterne 20 og 21.As shown in FIG. 2, the back side and the finger grip side of the handle are softly rounded, and furthermore the handle is made easy to grip thanks to a slight bend 24 between the lugs 20 and 21.

5 Takket være det brede mellemrum 15 mellem håndtagets fingergrebsside 14 og den tænkte forlængelse 12 af den retliniede del 7 af ægkanten muliggøres en lav knivføring, uden at betjeningspersonens fingre kommer til at støde mod et skæreunderlag, selv når kniven bevæges med den retliniede ægdel 7 parallelt med skæreunderlaget.5 Thanks to the wide gap 15 between the finger grip side 14 of the handle and the thoughtful extension 12 of the rectilinear portion 7 of the edge of the egg, a low knife guide is possible without the operator's fingers coming into contact with a cutting surface even when the knife is moved with the rectilinear egg part 7 in parallel. with the cutting base.

10 I kraft af den i det foregående omtalte forsætning af knivsbladet i forhold til håndtaget opnås det endvidere, at afstanden mellem dettes rygside 17 og ægkanten bliver forholdsvis stor, hvilket indebærer, at der kun skal små drejninger i håndleddet til for at 15 bevæge ægkanten med store sideudsving, hvorved friskæring af fiskefileter, navnlig i forhold til fiskenes rygben, lettes. Hertil bidrager også det forhold, at bredden af knivsbladet ikke behøver at være forøget i forhold til bredden af en normal fiskefi leteringskniv, nemlig som følge af den omtalte forsætning af både ægkanten og . 20 rygkanten.Furthermore, by virtue of the above-mentioned presumption of the knife blade relative to the handle, it is achieved that the distance between its back side 17 and the egg edge becomes relatively large, which means that only small turns of the wrist need to move the egg edge with large side swings, thereby facilitating the cutting of fish fillets, especially in relation to the fish's back legs. This also contributes to the fact that the width of the blade does not have to be increased in relation to the width of a normal fish-feeding knife, namely because of the mentioned presumption of both the edge of the egg and. 20 the back edge.

Ved den på tegningen viste udførelsesform har knivsbladet en længde på ca. 12 cm og en største bredde på ca. 2 cm, hvilket er ensbetydende med, at forholdet mellem længden og bredden er ca. 6. Imid-25 lertid kan dette forhold variere mellem 12 og 4 og ligger hensigtsmæssigt mellem 9 og 5. Det skal i denne forbindelse bemærkes, at forholdet mellem længden og bredden har stor betydning, idet knivsbladet ikke må være for smalt i forhold til længden, og ej heller for kort og bredt, idet for store udsving til disse to sider van-30 skeliggør tilvejebringelsen af et rent snit og opnåelse af renskæring.In the embodiment shown in the drawing, the knife blade has a length of approx. 12 cm and a maximum width of approx. 2 cm, which means that the length-to-width ratio is approx. 6. However, this ratio may vary between 12 and 4 and is conveniently between 9 and 5. It should be noted in this connection that the length-to-width ratio is of great importance, as the knife blade must not be too narrow in relation to the length. , nor too short and wide, as excessive swings to these two sides make it difficult to provide a clean cut and achieve clean cutting.
