Abstract
A leaf blower to be worn by a user. The leaf blower including a frame having a back plate defining a back plate plane and a blower system coupled to the frame. The blower system includes a motor having drive shaft, the drive shaft defining an axis, and the axis forms an angle with respect to the back plate plane between about 5 degrees and about 35 degrees.
Claims17
A leaf blower to be worn by a user, the leaf blower comprising:
- a frame including a back plate having an upper end and a lower end relative to the user wearing the leaf blower and defining a back plate plane;
- and
- a blower system coupled to the frame, wherein the blower system includes a motor having a drive shaft, the drive shaft defining a longitudinal axis, wherein the longitudinal axis forms an angle with respect to the back plate plane between about 5 degrees and about 35 degrees, wherein an intersection of the back plate plane and the axis of the drive shaft is proximate the upper end, and wherein the blower system includes an impeller coupled to an end of the drive shaft furthest from the intersection.
The leaf blower of clam 7, wherein the tube axis is substantially perpendicular the drive shaft.
