Abstract

A head (1) for a hedge trimmer comprising a main body (2), having a disc-shaped conformation, which can be connected to a drive shaft of a hedge trimmer to be placed in rotation about an axis of rotation (X). The main body (2) has at least one pair of primary seats (5) and one pair of secondary seats (6), each primary seat (5a) of the pair of primary seats (5) and each secondary seat (6a) of the pair of secondary seats (6) is a through seat. The pair of primary seats (5) is adapted to house a primary segment (S1) realised with a first cutting wire and arranged in a U-shaped arrangement between the primary seats (5a). The pair of secondary seats (6) is adapted to house a secondary segment (S2) realised with a second cutting wire and arranged in a U-shaped arrangement between the secondary seats (6a). Each primary seat (5a) of the pair of primary seats (5) has a primary transverse dimension (D1) and each secondary seat (6a) of the pair of secondary seats (6) has a secondary transverse dimension (D2).

Dependent claims

A head for a hedge trimmer comprising:

a main body (2) that can be connected to a drive shaft of a hedge trimmer to be placed in rotation about an axis of rotation (X), said main body (2) having a disc-shaped conformation;
wherein said main body (2) has at least one plurality of pairs of primary seats (5) and a plurality of pairs of secondary seats (6), each primary seat (5a) and each secondary seat (6a) being a through seat, wherein each pair of primary seats (5) is adapted to house a primary segment (S1) realised with a first cutting wire and arranged in a U-shaped arrangement between said primary seats (5a) and wherein each pair of secondary seats (6) is adapted to house a secondary segment (S2) realised with a second cutting wire and arranged in a U-shaped arrangement between said secondary seats (6a);
characterised in that said pairs of primary seats (5) alternate with said pairs of secondary seats (6) according to a circumferential direction about said axis of rotation (X);
and in that each primary seat (5a) of said pair of primary seats (5) has a first transverse dimension (D1) for housing a primary segment (S1) and each secondary seat (6a) of said pair of secondary seats (6) has a second transverse dimension (D2) for housing a secondary segment (S2), said first transverse dimension (D1) being greater than said second transverse dimension (D2) so that the pair of primary seats can house a primary segment (S1) having a larger transverse dimension than the transverse dimension of said secondary segment (S2) and different mechanical and/or physical and/or geometric properties from the secondary segment (S2).

1 more element

A method for loading a head for a hedge trimmer, wherein said head comprises a main body (2) that can be connected to a drive shaft of a hedge trimmer to be placed in rotation about an axis of rotation (X), said main body (2) having a disc-shaped conformation and having at least one pair of primary seats (5) and one pair of secondary seats (6), each primary seat (5a) of said pair of said primary seats (5) and each secondary seat (6a) of said pair of said secondary seats (6) being a through seat;

said method comprising the steps of inserting at least one primary segment (S1) in a respective pair of said primary seats (5) and inserting at least one secondary segment (S2) in a respective pair of said secondary seats (6), wherein said at least one primary segment (S1) is inserted in the respective pair of primary seats (5) in a direction leading towards a lower portion of the head intended to be turned towards the ground, and wherein said at least one secondary segment (S2) is inserted in the respective pair of secondary seats (6) in a direction leading towards an upper portion of the head opposite said lower portion.
