Definitions

  • the present invention relates to an inclinable polygonal wrench, the part of which situated lowest has a gripping section for engaging a recessed gripping surface of a screw and has also a groove between the upper and the lower part, which, in conjunction with the height of the lower part, makes it possible to incline the upper part.
  • Fig. 1 shows an upper part (2) which may be of appropriate shape and length, which means that the upper part can have a similar as well as a different shape as the bottom part (4) .
  • Pig. "I also shows a groove (3) in upper part (2) which is next to the lower part (4).
  • Groove (3) can be of different width, depth and shape, depending on the required degree of inclination.
  • the upper flank (7) of the groove is intended to guide the polygonal wrench towards the upper flank of the screw so as to achieve a good grip.
  • the flanks of the groove may be concave, inclined or straight. If required, the edges of the upper or lower flank or both flanks can be chamfered in order to reduce the friction when inclining the upper part.
  • Fig. 1 shows also part (4) situated lowest, the shape of which is, in this case, hexagonal, but it is possible to impart different shapes to the lower part, and fig. 2 shows certain different shapes, but there is of course no reason why other shapes should not occur.
  • the height of lower part (4) is adapted to the required gripping surface and the degree to which upper part (2) is inclined.
  • the upper flanks (7) of lower part (4) are equivalent to the shape of the groove.
  • Underside (5) of lower part (4) is flat, and in addition the edges (6) can be chamfered, which reduces friction.
  • Polygonal wrenches enabling the production of differently shaped upper parts have a lower part, the height of which is equal to the total gripping surface between the recessed gripping surface of the screw and the gripping surface of the lower part. If the upper part is inclined slightly, the gripping surfaces are concentrated at the deepest part of the screw's recess, thus achieving an optimal grip. If the gripping surface of the lower part is 5 n relation to the gripping surface of the screw's recess, the upper part can, if its length amounts to 95 mm, be inclined by about 40°.

Abstract

La partie de serrage d'une clef polygonale est délimitée par une rainure (3), ce qui permet d'adapter la partie de serrage au moment de serrage requis en modifiant sa hauteur. Le degré d'inclinaison de la partie supérieure (2) dépend de la forme de la rainure (3).
