Abstract

The multi-edged spanner has its grip part (2) limited by a track (3). The grip part can be adjusted to the requisite tightening torque by altering its height, and the shape of the track provides the degree of inclination adjustment of the key upper part.

Description

458 0a7 1 Bifogade ritningar och följande beskrivning bestyrker för- delarna med aktuell uppfinning. 458 0a7 1 The accompanying drawings and the following description attest to the advantages of the present invention.

Fig.l visar en överdel (2) som kan ha lämplig form och längd, detta innebär att överdelen kan ha likartad såväl som olik- artad form som nederdersta delen (4).Fig. 1 shows an upper part (2) which can have a suitable shape and length, this means that the upper part can have a similar as well as a different shape as the lower part (4).

Fig.1 visar också ett spår (3) i överdelen (2) som är närmast intill nedre delen (4). Spáret (3) kan ha olika bredd, djup och form beroende pá den snedställningsgrad som erfordras.Fig. 1 also shows a groove (3) in the upper part (2) which is closest to the lower part (4). The groove (3) can have different widths, depths and shapes depending on the degree of skew required.

Spárets översida (7) har funktion att styra flerkantnyckeln emot skruvens översida och på så sätt erhålla ett bra grepp.The upper side of the groove (7) has the function of guiding the multi-edge wrench against the upper side of the screw and thus obtain a good grip.

Spårets sidor kan vara konkava, sneda eller raka. Antingen över- eller undersidans eller båda sidornas kanter kan vid behov fasas för att minska friktionen vid snedställning av överdelen.The sides of the track can be concave, oblique or straight. Either the upper or lower side or the edges of both sides can be chamfered if necessary to reduce the friction when the upper part is tilted.

Fig.l visar också den längst ned belägna delen (4) vars form i detta fall är sexkantig, men det är möjligt att förse nedre delen med olika former och Fig.2 visar nägra olika former, men det är givetvis inget som hindrar att andra former kan förekomma. Höjden på nederdelen (4) anpassas till erforder- lig greppvta och snedställningsgrad av överdelen (2). Neder- delens (4) översidor (7) är ekvivalenta med spàrets form.Fig. 1 also shows the lower part (4) whose shape in this case is hexagonal, but it is possible to provide the lower part with different shapes and Fig. 2 shows some different shapes, but there is of course nothing to prevent others forms may occur. The height of the lower part (4) is adjusted to the required grip level and degree of inclination of the upper part (2). The upper sides (7) of the lower part (4) are equivalent to the shape of the groove.

Nederdelens (4) undersida (5) är plan-förutom kanterna (6) som fasas, vilket minskar friktionen. vad som tidigare beskrivits kan sammanfattas enligt följande: riei-kentnyekel med möjiiqhefernàila olika form pà överdelen, har en nederdel vars höjd är lika med den totala greppyta mellan skruvens infällda greppyta och nederdelens greppyta. vid liten snedställning av överdelen är greppytorna koncen- trerade till skruvspårets djupaste del, vilket innebär bästa grepp. Vid 35% greppyta på nederdelen i relation till skruv- spàrets greppyta, kan överdelen vid en längd av 95mm sned- ställas cirka 400.The underside (5) of the lower part (4) is flat except for the edges (6) which are chamfered, which reduces the friction. what has been previously described can be summarized as follows: riei-kentnyekel with möjiiqhefernàila different shape of the upper part, has a lower part whose height is equal to the total gripping surface between the recessed gripping surface and the gripping surface of the lower part. with a slight inclination of the upper part, the gripping surfaces are concentrated to the deepest part of the screw groove, which means the best grip. With a grip area of 35% on the lower part in relation to the gripping surface of the screw groove, the upper part can be inclined by approximately 400 mm at a length of 95 mm.

Pâ grund av tvà av varandra oberoende inställningar av grepp- yta och sncdställning, ökar detta möjligheterna att erhålla flerkantnyckel som kan tillfredställa de flesta krav.Due to two mutually independent settings of grip surface and cutting position, this increases the possibilities of obtaining a multi-edge wrench that can satisfy most requirements.
