Definitions

  • the present invention relates to a percussive or rotary-percussive tool known as a jackhammer, concrete breaker or perforator, whatever its energy source.
  • a percussive or rotary-percussive tool known as a jackhammer, concrete breaker or perforator, whatever its energy source.
  • a jackhammer a percussive tool known as a jackhammer, concrete breaker or perforator, whatever its energy source.
  • handles used to hold and guide the tool.
  • one solution consists in mounting the handles on a hollow cylindrical head which constitutes a sliding cylinder on the body of the hammer.
  • the present invention aims to avoid these drawbacks by providing a tool with hanging handles and which gives rise to no risk of jamming while allowing idling to loosen the pick. Much better, the invention aims to achieve a handle suspension system which is independent of the hammer itself, so this system can be adapted after the fact on an already existing hammer.
  • a hammer according to the invention comprises two handles surmounting the body of the tool, and it is characterized in that each handle is integral with a lever arm articulated on the top of the body of the hammer around an axis perpendicular to the longitudinal axis of said hammer.
  • the two levers are crossed, each carrying a handle, which makes it possible to give the assembly of an articulated lever and its handle, a total length twice that of the handle itself.
  • This extension of the lever arm of the articulated handles makes it possible to give the handles a large damping stroke without greatly varying their angle of inclination.
  • the assembly of the two handles and of the head on which they are articulated constitutes an independent assembly which can therefore be adapted as well on a new hammer specially designed for this, as on a hammer already existing or we adapt it afterwards.
  • the drawings show a concrete hammer 1, the head 2 of which carries two control handles 3 and 4.
  • each handle 3, 4 is integral with a lever referenced respectively 6, 7. These levers intersect and each of them comprises at its end a transverse cylindrical articulation pin, referenced respectively 8, 9.
  • each of the two levers 6, 7 can oscillate as does the corresponding handle 3, 4 as shown diagrammatically in FIG. 2 by the arrows 10 and 11.
  • the crossed arrangement of the levers 6 and 7 each having a long length makes it possible to obtain the largest lever arm possible to impart a large suspension stroke to the handles 3 and 4, while varying their angle of orientation to a minimum.
