Description

Øks for tynning av småskog. Ax for thinning woodland.

Oppfinnelsen omhandler en øks som The invention relates to an ax which

spesielt er beregnet for tynning av småskog, og det karakteristiske ved oppfinnelsen består i at et lett øksehode er forsynt is especially intended for thinning small forests, and the characteristic feature of the invention is that a light ax head is provided

med et knivorgan som peker i motsatt retning av øksebladet, som stort sett ligger with a knife member pointing in the opposite direction to the ax blade, which is mostly lying

i bladets plan, og hvis skjæreegg vender i in the plane of the blade, and whose cutting edge faces i

økseskaftets retning. Knivorganet kan the direction of the ax handle. The knife organ can

være smidd i ett stykke med øksehodet, be forged in one piece with the ax head,

men det er fortrinsvis avtagbart festet til but it is preferably removably attached

dette for lett utskifting og slipning. Befes-tigelsen kan skje på en hvilken som helst this for easy replacement and grinding. The attachment can take place on any

egnet måte. Knivorganet brukes med for-del ved kvisting, men også til å kutte rot-skudd og små busker som ved knivorganet suitable way. The knife organ is used with advantage for pruning, but also for cutting root shoots and small bushes as with the knife organ

kan kuttes helt nede ved roten. can be cut right down to the root.

Oppfinnelsen vil fremgå av tegningen: The invention will appear from the drawing:

Fig. 1 viser øksen i oppriss. Fig. 1 shows the ax in elevation.

Fig. 2 viser øksen sett fra siden. Fig. 2 shows the ax seen from the side.

Fig. 3 viser en variant i festemåten for Fig. 3 shows a variant in the attachment method for

knivorganet. the knife organ.

Et lett øksehode 1 er på vanlig måte A light ax head 1 is in the usual way

forsynt med et skaft 2. På øksehodet, og provided with a shaft 2. On the axe-head, and

i motsatt retning av øksebladet, er anbragt in the opposite direction to the ax blade, is placed

et knivorgan 3, som kan være festet til a knife member 3, which can be attached to

hodet ved hjelp av skruer 4. En annen the head using screws 4. Another

måte å feste knivorganet på er vist i fig. way of attaching the knife member is shown in fig.

3, hvor knivorganet er anbragt i en sliss i 3, where the knife member is arranged in a slot i

øksehodet og festet med gjennomgående the ax head and fixed with through

skruer 7, som er slik anbragt at hverken screws 7, which are arranged in such a way that neither

hodet eller mutteren raker utenfor øksehodets sider. the head or nut protrudes beyond the sides of the ax head.

Retningen av egglinjen 5 kan varieres, The direction of the egg line 5 can be varied,

men i det viste eksempel skråner egglinjen oppover fra øksehodets nedre del, og but in the example shown the egg line slopes upwards from the lower part of the axe-head, and

oppover mot knivorganets endeparti og upwards towards the end part of the knife body and

tets midtakse. Knivorganets endeparti har en nedadrettet nese 6 som stikker forbi egglinjen 5 og har til hensikt å hindre at kvister og småstammer glipper over kniv-enden under kuttingen. t's central axis. The end part of the knife member has a downward-directed nose 6 which protrudes past the egg line 5 and is intended to prevent twigs and small stems from slipping over the knife end during cutting.

Knivorganet kan også utføres med konkavt buet egglinje, men dette vanske-liggjør slipningen og er derfor mindre for-delaktig. Andre varianter er også mulige innenfor rammen av de oppstillete patent-påstander. The knife member can also be made with a concavely curved egg line, but this makes sharpening difficult and is therefore less advantageous. Other variants are also possible within the scope of the listed patent claims.
