Themotor 122 may be secured to the secondelongated member 120 via several mountingbrackets 126, and may include aswitch 128 that can be activated to energize themotor 122. Since themotor 122 is mounted away from thebrush head assembly 112, contaminants such as water, soap, soil, or grease typically located in the vicinity of the brush heads 40,42 do not contact themotor 122. - The
telescopic drive shaft 124 may include afirst drive member 130 in telescopic relationship with asecond drive member 132. Thefirst drive member 130 may be fixedly secured to the firstelongated member 118 via a mountingbracket 134, and may include a keyway or other internal mechanism that transmits rotary motion from thesecond drive member 132 to thefirst drive member 130 while permitting relative axial movement therebetween. During operation, thetelescopic motor assembly 110 can be configured to drive a rotary brush head in a manner similar to that described above with respect torotary brush 10. - FIG. 8 is a perspective view of a
rotary brush 136 in accordance with another exemplary embodiment of the present invention.Rotary brush 136 may be configured similar torotary brush brush head assembly 138, atelescoping handle 140, and amotor 142 configured to drive a rotary brush on thebrush head assembly 138. - The telescoping handle140 may include a first
elongated member 144 in telescoping relationship with a secondelongated member 146. The first elongated member may have oneend 148 secured to thebrush head assembly 138, and anopposite end 150 slidably disposed within the secondelongated member 146. The secondelongated member 146, in turn, includes oneend 152 configured to slidably receiveend 150 of the firstelongated member 144, and anopposite end 154 connected to aremovable end cap 156. Anelastomeric sleeve 158 of rubber, foam plastic or other suitable member disposed about the secondelongated member 140 forms a grip that can be used to manipulate therotary brush 136 by the operator. - In the illustrative embodiment depicted in FIG. 8,
rotary brush 136 is configured to store and deliver a cleaning agent such as window cleaner or liquid soap within thetelescopic handle 140 without the use of a hose or other external source of fluid. In a fully expanded position depicted in FIG. 9, the secondelongated member 140 defines aninternal chamber 160 configured to receive the cleaning agent. Theend 154 of the secondelongated member 146 may be configured to threadably receive theremovable end cap 156, allowing the user to fill and then seal theinternal chamber 160 with the cleaning agent. - Operation of
rotary brush 136 is similar to that described above with respect torotary brush brush head assembly 138, a pumping force may be applied by retracting the firstelongated member 144 into the secondelongated member 146, resulting in an increase in pressure within theinternal chamber 160. As shown in FIG. 10, retraction of the firstelongated member 144 into the secondelongated member 146 causes the cleaning agent to compress within theinternal chamber 160, forcing the cleaning agent through alumen 162 disposed within the firstelongated member 144 and into thebrush head assembly 138. Continued pumping action of the firstelongated member 144 within the secondelongated member 146 delivers additional cleaning agent to thebrush head assembly 138, as desired, until theinternal chamber 160 is completely exhausted of cleaning agent. - Having thus described the several embodiments of the present invention, those of skill in the art will readily appreciate that other embodiments may be made and used which fall within the scope of the claims attached hereto.
