- Figure 2 is a section view of the device of Figure 1.
- Figure 3 is a partial cross section view of Figure 1.

- Figure 6 is an exploded perspective view of the locking mechanism.
- Figure 7 is a cross-section view of the stop mechanism along line 7-7 of Figure 8.
- Figure 8 is a cross-section view along line 8-8 of Figure 5.
- Figure 9 is a cross-section view along line 9-9 of Figure 1.
- Turning to the figures, a scrubbing device is illustrated and designated with the reference numeral 10. The scrubbing device includes a
head 12, a support member 14 and ahandle 16. Thehandle 16 includes acoupling member 18 to connect the scrubbing device 10 with ahose 20. - The
handle 16 includes a clamshell housing 22 with a grip portion 24, as well as anaperture 26 to enable the users hand to pass through the aperture and secure on the grip portion 24. Abattery 28 is inserted through anaperture 30 at one end of the housing 22. Thehandle 16 includes ahose retention member 32. The hose retention member includes a latch 34 and anarcuate groove 36 which receives thehose 20. The latch 34 extends over thehose 20 locking the hose in thegroove 36 so that the hose does not place a large bending moment on thehose connecting element 18. - The
hose connecting element 18 is connected to aconduit 40. Theconduit 40 passes water from the hose to the scrubbinghead 12. A switch 42 on thehandle 16 controls the power to the motor. Thus, the motor may be turned on and off by switch 42. Also, avalve 41 integrated withelement 18, associated with theconduit 40, enables variable volumes of the water to pass to the scrubbing head so that the amount of water can be controlled to the surface to be cleaned. - An
air pump 44 is positioned within thehandle 16. See Figure 9. Theair pump 44 can be controlled by switch 46. The air pump is electrically coupled with thebattery pack 28. Theair pump 44 controls the amount of fluid sprayed out of the second fluid source. - The support 14 includes a number of
sections 50 to enable telescoping of the support 14. Further, a gripping member 52 may be positioned on the outside of the support member. Theconduit 40 is positioned between the gripping member 52 and the support 14 until it reaches aspacer 54. Theconduit 40 includes aspiral conduit portion 56 which elongates to enable telescoping of the support 14. Thespiral conduit portion 56 connects with a lower conduit portion of the first fluid source. A spiraled wire 60, as well asair hose 62, are inside of thesections 50 of the support 14. The wire 60 is electrically connected with switch 42 and, in turn,battery 28 to drive theelectric motor 64 and in turn the scrubbing device on thescrubber head 12. Theair hose 62 extends from one of thesupport sections 50 and passes into thereservoir 66 of the lower portion 58. - The lower portion 58 includes the
cleaning solution reservoir 66, as well as afork portion 68 which couples with thehead 12. Thecleaning solution reservoir 66 may be removable from the lower portion 58. Theair hose 62 couples with an inlet to thecleaning solution reservoir 66. Thecleaning solution reservoir 66 includes anoutlet 70 which includes another conduit 72 which passes into thescrubber head 12 and connects with thenozzle 74. Thus, fluid cleaning solution is moved from thereservoir 66, via thepump 44, and sprays out thenozzle 74. - The
fork 68 of the lower portion pivotally secures with thehead 12. Thefork portion 68 includes apivot locking mechanism 80 which enables thehead 12 to be locked in at least one position and also enables free motion of the head about thefork 68. - Moving to Figures 5 through 8, a better explanation of the locking mechanism may be obtained.
- The
head housing 100 includes aboss 120 having a cam retention area 122 and apivot pin 124. The cam retention area 122 includes a plurality ofrecesses 126 andprojections 128 which receive ahead locking gear 130. - The
head locking gear 130 is a metal gear including a plurality ofprojections 132 and recesses 134. Theprojections 132 and recesses 134 mate with the boss recesses andprojections head locking gear 130 is secured in position in theboss 120. One of therecesses 134 includes awedge 136, which projects through aslot 138 in theboss 120. Thewedge 136 acts as a stop to halt the rotation of thefork 68 on thehead 12, which will be explained herein. - The
pivot locking mechanism 80 includes arotatable knob 142 and a slidingcam plate 144. Therotatable knob 142 includes an offset receivingportion 143 to retain theknob 142 onto thepivot 124. Theknob 142 includes aneccentric cam surface 146. Thecam surface 146 abuts against atab 148 of the slidingcam plate 144. Thecam plate 144 includes atab 145 which retains a plurality ofpins 150 which mate in therecesses 134 of thehead locking gear 130. Thepins 150 are loaded bysprings 152, which are retained in ahousing portion 154 of thefork 68. Aplate 155 secures the slidingcam plate 144 in thehousing portion 154. - The
housing portion 154 includes anarcuate portion 156 and arectangular portion 158. Thearcuate portion 156 fits around thecylindrical boss 120 enabling thefork 68 to rotate about theboss 120. Thearcuate portion 156 has ends 160 and 161 which act as stops and abut thewedge 136 stopping rotation of thefork 68. Thus, thewedge 136 acts as a stop to limit the rotation in both directions of the fork 68 (see Figure 7). The slidingcam plate 144, withpins 150 biased bysprings 152, are positioned in therectangular portion 158 of thehousing 154. As theknob 142 is rotated, witheccentric cam surface 146 abutting againsttab 148, the slidingcam plate 144, as well aspins 150, is moved in thehousing portion 158. This movement removes thepins 150 from therecesses 134 of thehead locking gear 130. This enables the fork to be rotated into a different position. As the user finds the desired position, theknob 142 is rotated in a reverse direction to enable thepins 150 to engagedifferent recesses 134 in thehead locking gear 130 to lock thefork 68 in a different position with respect to thehead 12. In the free motion position, theknob 142 is rotated, which, in turn, moves the slidingcam plate 144, as well aspins 150, away from thehead locking gear 130 out of engagement withrecesses 134. In this position, thepins 150 do not extend into therecesses 134. Thus, thefork 68 can rotate until thestops 160 and 161contact wedge 136 halting the rotation of thefork 68. - The
head 12 is submersible into a liquid such as water and has a water tight seal. Thus, thehead 12 may be placed into a bucket of water or the like when in use. Thehead 12 includeshousing 100 surrounding themotor 64 positioned within thehousing 100. A cleaning device, such as abrush 102, is secured to amotor shaft 104 of themotor 64. Thehousing 100 includespassageways 106 to enable the soap and water conduits to pass to thenozzles nozzle 108 is coupled with thewater conduit 40. - The cleaning
member 102 includes aretention member 110 which has acircumferential wall 112. Thewall 112 defines abore 114. Acircumferential flange 116 is positioned on the interior surface of thebore 114. The circumferential wall includes slots forming sections which, in turn, formfingers 118 to retain the cleaningmember 102 onto themotor shaft 104. Thewall 112 is placed on the shaft and is expanded due to the flange. Once the flange intercepts the groove, the wall is secured on the shaft. - The scrubbing device 10 includes a first fluid source which includes the
hose connection 18,conduit 40 andnozzle 108. A second fluid source which is operable by thepump 44 viahose 62, includesreservoir 66, hose 72 andnozzle 74. In operation, thevalve 41 connected with theconduit 40 is open to enable fluid from the hose to pass into theconduit 40. This fluid passes through theconduit 40 through the spiral section and out ofnozzle 108. The switch 46 activates thepump 44. This forces air into thehose 62 which, in turn, pressurizes thereservoir 66. As thereservoir 66 pressurizes, cleaning solution in the reservoir is passed through hose 72 and out ofnozzle 74. The switch 42 can activate the cleaning device at any time during these operations. Thus, cleaning solution and water are separately ejected from the scrubber and are not mixed with one another prior to ejection onto the surface to be cleaned. - Thus, a cleaning device is provided which may be extended to reach vertical heights above the user. Also, the device may be positioned in a free motion pivoting position so that the head may continue to follow the surface as it is scrubbed. Further, the invention provides a lightweight battery operated scrubbing device, which is easily manipulated by the user.
