Abstract
A power sweeper has a handle having a first end graspable by a user and a second end, a drive shaft extending along the handle, and a power head coupled to the handle to rotate the drive shaft. A gear box is coupled to the drive shaft adjacent the second end, and a brush is coupled to the gear box for rotation in response to rotation of the drive shaft. The power sweeper includes an axle, and first and second wheels coupled to the axle. A shield is coupled to the gear box and defines an aperture through which the handle extends. The axle is moveable with respect to the shield and the brush to adjust an angle between the handle and the ground surface.
Claims17
A power sweeper comprising:
- a handle having a first end and a second end graspable by a user;
- a drive shalt extending along the handle;
- a power head coupled to the handle to rotate the drive shaft;
- a gear box coupled to the drive shalt adjacent the first end;
- a brush coupled to the gear box for rotation in response to rotation of the drive shaft;
- an axle;
- a first wheel coupled the axle, the first wheel configured to roll along a ground surface;
- a second wheel coupled to the axle, the second wheel configured to roll along the ground surface;
- a shield coupled to the gear box, the shield defining an aperture through which the handle extends;
- and
- a bracket coupled to the axle and the bracket coupled to the shield, wherein the axle is moveable with respect to the shield and the brush to adjust an angle between the handle and the ground surface, and wherein the bracket slides along the shield to move the first wheel, the second wheel, and the axle relative to the shield to adjust the angle between the handle and the ground surface.
A method of adjusting an angle of a handle of a power sweeper with respect to a support surface, the method comprising:
- coupling a pair of wheels to an axle;
- coupling a support member to the axle;
- coupling a shield to the support member;
- coupling a handle to the support member;
- extending a drive shaft through the handle;
- coupling a power head to a first end of the drive shaft;
- coupling a brush to a second end of the drive shaft;
- rotating the brush with the drive shaft in response to operation of the power head;
- and
- moving the support member with respect to the shield to move the pair of wheels and the axle relative to the shield to change an angle between the handle and the support surface.
A power sweeper configured to be coupled to a power head, the power sweeper comprising:
- a handle graspable by a user;
- a first wheel and a second wheel coupled to the handle;
- an axle extending between the first wheel and the second wheel;
- a brush coupled to at least one of the handle, the first wheel and the second wheel;
- a drive shaft coupled to the brush to rotate the brush, the drive shaft configured to be rotated by the power head;
- a shield coupled to the wheel, the shield defining an aperture through which the handle extends;
- and a bracket coupled to the axle and coupled to the shield, wherein the shield is moveable with respect to the wheel to adjust an angle between the handle and a ground surface, and wherein the bracket slides along the shield to move the first wheel, the second wheel, and the axle relative to the shield to adjust the angle between the handle and the ground surface.
