i DK 171510 B1in DK 171510 B1

Den foreliggende opfindelse angår et apparat til at flå skindet fra et ben samt til at overskære benet på et dyr, fortrinsvis mink eller ræv, og omfattende en benkrog til indføring mellem dyrets skind og ben for at skille disse fra hinanden samt en svingbar kniv, der er anbragt i 5 umiddelbar nærhed af benkrogen for at overskære benet nær dyrets pote.The present invention relates to an apparatus for peeling the skin from one leg and for cutting the leg of an animal, preferably mink or fox, and comprising a leg hook for insertion between the animal's skins and legs to separate them from one another, and a pivotal knife which is placed in the immediate vicinity of the leg hook to cut the leg near the animal's paw.

Et apparat af denne type kendes fra US-patentskrift nr. 3.409.936. Ved dette kendte apparat anvendes en svingbar kniv, som svinger frem og tilbage imod benkrogen. Når skindet skal flås af bagbenet på et dyr, 10 anbringes benkrogen mellem skindet og benet. Herefter trækkes dyret langs med benkrogen, indtil dyrets pote befinder sig i umiddelbar nærhed af benkrogen. Herefter aktiveres kniven, og benet overskæres nær dyrets pote. Når det andet bagben på dyret skal flås, og poten skal afskæres, vil det være nødvendigt for operatøren at dreje dyret til 15 venstre og højre i forhold til benkrogen. Det kendte apparat vil således være langsommelig og besværlig at anvende.An apparatus of this type is known from U.S. Patent No. 3,409,936. In this known apparatus, a pivotal knife is used which pivots back and forth against the leg hook. When the skin is to be peeled off the hind leg of an animal, the leg hook is placed between the skin and the leg. Thereafter, the animal is pulled along the leg hook until the animal's paw is in the immediate vicinity of the leg hook. The knife is then activated and the leg is cut near the animal's paw. When the other hind leg of the animal has to be peeled and the paw has to be cut off, it will be necessary for the operator to turn the animal to 15 left and right relative to the leg hook. Thus, the known apparatus will be slow and cumbersome to use.

Erfaringer har vist, at dyret skal drejes ca. 90e mellem de to overklipninger af et ben. Endvidere vil den skrå orientering af benet 20 imellem benkrogen og kniven forårsage en risiko for, at benet klippes spidst. Dette medfører en risiko for, at der optræder splinter, som kan ødelægge skindet.Experience has shown that the animal must be turned approx. 90e between the two clippings of one leg. Furthermore, the oblique orientation of the leg 20 between the leg hook and the knife will cause a risk of the leg being cut sharply. This causes a risk of splinters that can damage the skin.

Det er formålet med den foreliggende opfindelse at anvise et apparat 25 af den indledningsvis nævnte type, hvori ulemperne ved den kendte teknik er afhjulpet, og som er hurtigt og enkelt at anvende.It is the object of the present invention to provide an apparatus 25 of the type mentioned in the beginning, in which the disadvantages of the prior art are remedied and which are quick and easy to use.

Dette opnås ifølge den foreliggende opfindelse med et apparat, som er særpræget ved, at den svingbare kniv er en med afskærmning dækket 30 kniv, som er forsynet med en æg på begge sider og er indrettet til at svinge fra den ene side af benkrogen til den anden gennem en slids i denne.This is achieved according to the present invention with an apparatus which is characterized in that the pivotal knife is a shielded 30 knife which is provided with an egg on both sides and is adapted to swing from one side of the leg hook to the second through a slit in this one.

Idet den svingbare kniv er forsynet med en æg på begge sider og kan 35 svinge gennem benkrogen, bliver det muligt at foretage overskæring af benet ved knivens svingningsbevægelse i begge retninger. Når en operatør således har ført benkrogen mellem dyrets ben og skind og trukket dyret tilbage, således at benkrogen befinder sig nær poten, kan det første ben overskæres. Overskæringen vil ske stort set vinkelret på 2 DK 171510 B1 benet ved knivens svingning imod og gennem benkrogen. Når kniven er svinget til den modsatte side, er apparatet klar til brug, og operatøren kan føre benkrogen mellem skindet og benet på det andet ben. Herefter kan flåning og overskæring gentages. Ved behandlingen af dyrets 5 begge ben vil dyret blive holdt i stort set samme stilling i forhold til apparatet. Dette gør apparatets anvendelse lettere og hurtigere end de kendte apparater.Since the pivotal knife is provided with an egg on both sides and can swing through the leg hook, it becomes possible to cut the leg by the pivotal movement of the knife in both directions. Thus, when an operator has guided the leg hook between the animal's leg and skin and retracted the animal so that the leg hook is near the paw, the first leg may be cut. The cutting will take place almost perpendicular to the 2 DK 171510 B1 leg when the blade pivots against and through the leg hook. When the knife is swung to the opposite side, the device is ready for use and the operator can guide the leg hook between the skin and the leg of the other leg. After this, skinning and cutting can be repeated. In the treatment of both legs of the animal, the animal will be held in substantially the same position relative to the apparatus. This makes the use of the device easier and faster than the known devices.

Idet kniven er afskærmet, undgås endvidere risiko for, at operatøren 10 koraner til skade. Hvis skærmen er forskydelig, således som anført i krav 3, kan skærmens position benyttes som en indikation for knivens stilling, således at operatøren umiddelbart ved, på hvilken side af benkrogen dyrets skind henholdsvis ben skal placeres ved en begyndende anvendelse af apparatet. Såfremt afskærmningen er uafhængigt fjederpå-15 virket og samtidig har en nedefterrettet krumning imod benkrogen, vil skærmen automatisk føres væk fra benkrogen imod virkningen fra en fjeder, når dyrets ben presses ned mellem benkrogen og skærmen.Furthermore, as the knife is shielded, there is a risk that the operator may damage 10 Qurans. If the screen is slidable, as stated in claim 3, the position of the screen can be used as an indication of the position of the knife, so that the operator knows immediately on which side of the leg hook the animal's skins or legs should be placed, respectively, upon initial use of the apparatus. If the guard is independently spring-acting and at the same time has a downward curvature against the leg hook, the screen will automatically be moved away from the leg hook against the action of a spring when the animal's leg is pressed down between the leg hook and the screen.

Kniven er fortrinsvis indrettet med en krumning og er hulslebet på de 20 to kanter for dannelse af de to æg.The knife is preferably arranged with a curvature and is hollowed on the two two edges to form the two eggs.

Opfindelsen vil herefter blive forklaret nærmere under henvisning til den medfølgende tegning, hvor 25 fig. 1 viser et partielt billede af et apparat ifølge opfindelsen, således som set fra siden, fig. 2 viser et billede af det i fig. 1 viste apparat, således som set ovenfra, og fig. 3 viser et partielt billede af en benkrog, der indgår i appa-30 ratet.The invention will now be explained in more detail with reference to the accompanying drawing, in which: FIG. 1 shows a partial view of an apparatus according to the invention, as seen from the side; FIG. 2 is a view of the embodiment of FIG. 1, as seen from above, and FIG. 3 shows a partial view of a leg hook included in the apparatus.
