  • Patent number: 11802532
    Abstract: The present disclosure relates to a starter pulley arrangement for an internal combustion engine. The arrangement comprises a cord drum (1) configured to house a starting rope wound thereon, a driver (3) configured to interact with a flywheel (5) or other part connected to an engine crankshaft, and a torsion spring (7) connecting the cord drum (1) to the driver (3), such that the cord drum can resiliently urge the engine crankshaft via the driver. The torsion spring (7) is tensioned in a resting position where the driver does not influence the crankshaft. This provides an improved resistance against wear on the parts of the starter pulley arrangement.

  • Publication number: 20210402494
    Abstract: The present disclosure relates to a chainsaw 1 comprising a housing 3, a guide bar 5, projecting from the housing 3, and one or more handles 9. The guide bar 5 has a main direction of extension 15 defined by its center-line. The housing comprises an outer shell 3 made of plastic, which has at least a first 23 outer groove filled with a contrasting plastic material, wherein the groove at least partly extends straight in a transverse direction 17 that deviates less than 3 degrees from a direction perpendicular to the main direction 15 of extension of the guide bar 5. This provides an indication that facilitates precise and safe felling of trees.
