Abstract
A floor sweeper includes a body, an electric motor mounted within the body, a main brush mounted to the body and extending transversely thereof and driven by the electric motor to rotate. The floor sweeper also includes an auxiliary brush mounted to the body and driven to rotate about a vertical axis independently of the electric motor and main brush.
Description
- The present invention relates to floor sweepers. More particularly, although not exclusively, the invention relates to a motorised floor sweeper having auxiliary brushes that can clean up to an edge such as a skirting board for example.
- Electric floor sweepers having motor-driven brushes are known. These comprise a transverse horizontal main brush including an array of radiating bristles—the brush being driven to rotate by an electric motor ouch that the tips of the bristles contact the floor surface and sweep dust and debris therefrom into a receiving bin within the sweeper body. Such floor sweepers having auxiliary brushes that rotate about a substantially vertical axis are also known. Such auxiliary brushes flank the transverse horizontal brush and are driven by a take-off mechanism therefrom. The ancillary brushes have bristles that project transversely of the sweeper body such that their tips extend to the edge of a room such an at a skirting board. Rotation of the main brush results in rotation of the auxiliary brushes. A problem associated with such devices is that the auxiliary bristles rob power from the main brush. Should the auxiliary brushes become jammed, the main brush will also jam.
- It is an object of the present invention to overcome or substantially ameliorate the above disadvantages and/or more generally to provide an improved floor sweeper having auxiliary brushes driven independently of a main sweeping brush.
- There is disclosed herein a floor sweeper comprising:
-
- a body,
- a main brush mounted to the body and extending transversely thereof and driven to rotate,
- an auxiliary brush mounted to the body and driven to rotate about a substantially vertical axis independently of the main brush.
- Preferably, the floor suite for further comprises an electric motor mounted within the body and driving the main brush.
- Preferably, the floor sweeper further comprises a drive pulley attached to an output shaft of the electric motor, a driven pulley upon the main brush, and a drive belt extending about the drive pulley and driven pulley.
- Preferably, the floor sweeper further comprises surface-engaging wheels attached to the body and wherein the auxiliary brush is driven to rotate by one of the surface-engaging wheels.
- Preferably the floor sweeper further comprises another auxiliary brush—the main brush being flanked by the auxiliary brushes and wherein said another auxiliary brush is driven to rotate by another of said surface-engaging wheels.
- Preferably, the floor sweeper further comprises a wheel pulley attached to each surface-engaging wheel and an auxiliary pulley attached to each auxiliary brush and a drive belt extending between each respective wheel pulley and auxiliary pulley.
- A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings, wherein:
-
FIG. 1 in a schematic prospective illustration of, key parts of an electric floor sweeper, -
FIG. 2 is a schematic cross-sectional plan view of a floor sweeper body encasing the key parts ofFIG. 1 , and -
FIG. 3 is a schematic parts-exploded prospective illustration of the key parts of the floor sweeper an depicted inFIG. 1 - In the accompanying drawings there is depicted schematically a
floor sweeper body 10 typically fabricated from moulded plastics material. Mounted within thebody 10 is anelectric motor 11 that would typically received power from one or more rechargeable batteries housed within thebody 10. Theelectric motor 11 drives amain brush 12 havingbristles 13 extending radially therefrom. Do this end, the motor and 11 has adrive pulley 13 about which a bill to 14 extends. Thebelt 14 passes about a drivenpulley 15 at one end of themain brush 12. Upon activation of theelectric motor 11, thebelt 14 causesmain brush 12 to rotate about a horizontal axis such that the chips of the bristles for 10 contact a floor surface to thereby sweep debris into adustbin 20 within thebody 10. - The floor sweeper comprises a pair of
auxiliary brushes 17 flanking themain brush 12. Biggs Hillary brushes 17 rotated about a substantially vertical axis and each comprise anauxiliary pulley 18. - There is a pair of floor-
engaging wheels 16 mounted to thebody 10 and these each have attached thereto amain wheel pulley 21 about which they belted 19 extends. Eachbelt 19 extends about a respective one of theauxiliary pulleys 18. As a result, motion of the body turned over a floor surface results in rotation of theancillary brushes 17 in order to sweep dust and debris from a floor region immediately adjacent to a skirting board for example into the path of themain brush 12 that would in turn sweep that dust and debris into thedustbin 20. - It should be appreciated that modifications and alterations obvious to those skills in the art are not to be considered as beyond the scope of the present invention. For example, the
auxiliary brushes 17 might be driven by an independent motor or motors. Furthermore, themain brush 12 might not be driven to rotate by an electric motor. Instead, it might be driven to rotate by a floor-engaging wheel. - The floor sweeper can be used to clean a floor surface and should one of the auxiliary brushes become jammed in use, this will not result in jamming of the
main brush 12.
