Description
Claims (9)
- A handle unit (1) for a handheld working tool (2), such as a chain saw, cutting machine or hedge trimmer, wherein said unit comprises a drive unit (3) with an engine and a cutting unit (4) such as a guide bar (4) with saw chain, cutting disc or shears, and at least one attachment frame (7) mounted to said drive unit, said unit also comprises two mutually associated hand grips (5, 6), which, during use of said saw, are located higher up than said drive unit, and at least one handle support (8) intended for detachable attachment in different positions along said attachment frame (7), so that said hand grips can be rotated relative to said handle unit and that the orientation (16) of said cutting unit can be changed between vertical and horizontal positions, said handle unit is further provided with a single down-projecting part (9) located on the backside (10) of said hand grips opposite to the cutting side (11), so that engine controls, such as throttle cable and an electric stop control cord, which are arranged to lead from at least one of said hand grips (5, 6) to the rear side of the drive unit, are protectively mounted thereto, said down-projecting part terminates in a rear attachment (12) which pivotally co-operates with said handle support (8) and provides said orientation means together with a rear drive unit attachment (13) located on the rear side (10) of said drive unit to enable said relative rotation, said down-projecting part is further shaped as a V having its top-point, or meeting-point, down at said rear attachment (12) and its upper ends at each hand grip and the branches of the shaped V are stabilized by a cross-bar (26) and two additional bars (27, 28) support the handle support (8) and connect it with the down-projecting part.
- A handle unit (1) according to claim 1, characterized in that the handle unit is provided with a fuel tank (36), whose fuel hose is mounted to the down-projecting part (9) and thus being protected.
- A handle unit (1) according to claim 1 or 2, characterized in that engine controls, such as a throttle cable, an electric cord for stop control or a possible fuel hose, are mounted to the down-projecting part (9), except for at the lowest part of the down-projecting part (9), where they pass over to the drive unit.
- A handle unit (1) according to any one of the preceding claims, characterized in that the hand grips (5, 6) are arranged around handle tubes (37, 38), which extend down in the down-projecting part (9), and the engine controls, and a possible fuel hose, are mounted to the down-projecting part in such a manner that they extend inside at least one of the handle tubes.
- A handle unit (1) according to claim 4, characterized in that the handle tubes (37,38) extending down in the down-projecting part (9) are arranged as a V, and they are mounted to be upwards and downwards adjustable, so that during a raising the height of the handle unit as well as the 5 distance between the hand grips (5, 6) will increase.
- A handle unit (1) according to any one of the preceding claims, characterized in that the attachment frame (7) over most part of its length is arranged as a double frame, i.e. with two mutually parallel frame parts, which are cooperating with the handle support (8).
- A handle unit (1) according to any of the preceding claims, characterized in that the rear attachment (12) is arranged in the down-projecting part (9).
- A handle unit (1) according to any one of the preceding claims, and the drive unit (3) comprises an anti-vibrated part (17) mounted to an engine supporting part (18) by means of anti-vibration elements (19), characterized in that the attachment frame (7) is mounted to the anti-vibrated part.
- A handle unit (1) according to claim 8, characterized in that the rear drive unit attachment (13) is arranged in the anti-vibrated part (17).
