Handle arrangement for a blower
Handle ( 20 ) or handles for a blower ( 10 ) carried in the back of an operator. The handle ( 20 ) or handles are placed on a stiff section ( 15 ) of a blower tube ( 13 ) extending from the blower ( 10 ). A longitudinal axil of the handle ( 20 ) or handles is placed outside the circumference of the stiff section ( 15 ) of the blower tube ( 13 ) when seen in a plane perpendicular to the longitudinal axle of the stiff section ( 15 ) of the blower tube ( 13 ). The projection of the longitudinal axle of the handle ( 20 ) in said plane is parallel to a straight line extending through the geometrical center of the cross section ( 15 ) of the blower tube ( 13 ).
1 . Handle ( 20 ) or handles for a blower ( 10 ) carried on the back of an operator, said handle ( 10 ) or handles are placed on a stiff section ( 15 ) of a blower tube ( 13 ) extending from the blower ( 10 ), characterised in that a longitudinal axle (A) of the handle ( 20 ) or handles is places outside the circumference of the stiff section ( 15 ) of the blower tube ( 13 ) when seen in a plane perpendicular to the longitudinal axle of the stiff section( 15 ) of the blower tube ( 13 ), and that the projection of the longitudinal axle (A) of the handle ( 20 ) in said plane is parallel to a straight line (L) extending through the geometrical centre of the cross section of the stiff section( 15 ) of the blower tube ( 13 ).
2 . Handle ( 20 ) according to claim 1 , characterised in that the cross section of the stiff section ( 15 ) to the blower tube ( 13 ) is a circle.
3 . Handle according to claim 1 or 2 , characterised in that the handle ( 20 ) or handles are placed so that the distance from the outer side of the blower tube ( 13 ) to a surface ( 25 ) on the handle where the operators hand is placed during normal use of the tool not exceeds 100 millimeters.
4 . Handle according to claim 3 , characterised in that the distance is between 15 to 60 millimeters.
5 . Handle according to claim 1 , characterised in that the handle ( 20 ) or handles is movable around the circumference of the blower tube ( 13 ).
6 . Handle according to claim 1 , characterised in that the position of the handle ( 20 ) or handles in axial direction along the tube ( 13 ) is adjustable.
7 . Handle according to claim 1 , characterised in that the blower tube ( 13 ) is provided with one handle ( 20 ) or handle bar comprising two handles.
8 . Handle according to claim 1 , characterised in that the handle ( 20 ) or handles are placed on a curved arm ( 21 ) so that the position of the handle ( 20 ) or handles are closer to the operator than the position where the curved arm ( 21 ) is secured to the blower tube ( 13 ).
9 . Handle according to claim 8 , characterised in that curved arm ( 21 ) is secured to the blower tube ( 13 ) by a loop ( 22 ) surrounding the blower tube ( 13 ).
10 . Handle according to claim 9 , characterised in that the loop ( 22 ) is secured to the blower tube ( 13 ) by a screw ( 24 ) activated by a wheel ( 23 ).
11 . Handle according to claim 10 , characterised in that the curved arm ( 21 ) and the handle ( 20 ) is turnable when the screw ( 24 ) is released so that the angle between the longitudinal axle (A) of the handle ( 20 ) in relation to the longitudinal axle of the blower tube ( 13 ) is changed.
