  • the spiral conduit portion 56 connects with a lower conduit portion of the first fluid source.
  • a spiraled wire 60, as well as air hose 62, are inside of the sections 50 of the support 14.
  • the wire 60 is electrically connected with switch 42 and, in turn, battery 28 to drive the electric motor 64 and in turn the scrubbing device on the scrubber head 12.
  • the air hose 62 extends from one of the support sections 50 and passes into the reservoir 66 of the lower portion 58.
  • the lower portion 58 includes the cleaning solution reservoir 66, as well as a fork portion 68 which couples with the head 12.
  • the cleaning solution reservoir 66 may be removable from the lower portion 58.
  • the air hose 62 couples with an inlet to the cleaning solution reservoir 66.
  • the cleaning solution reservoir 66 includes an outlet 70 which includes another conduit 72 which passes into the scrubber head 12 and connects with the nozzle 74. Thus, fluid cleaning solution is moved from the reservoir 66, via the pump 44, and sprays out the nozzle 74.
  • the fork 68 of the lower portion pivotally secures with the head 12.
  • the fork portion 68 includes a pivot locking mechanism 80 which enables the head 12 to be locked in at least one position and also enables free motion of the head about the fork 68.
  • the head housing 100 includes a boss 120 having a cam retention area 122 and a pivot pin 124.
  • the cam retention area 122 includes a plurality of recesses 126 and projections 128 which receive a head locking gear 130.
  • the head locking gear 130 is a metal gear including a plurality of projections 132 and recesses 134.
  • the projections 132 and recesses 134 mate with the boss recesses and projections 126 and 128 so that the head locking gear 130 is secured in position in the boss 120.
  • One of the recesses 134 includes a wedge 136, which projects through a slot 138 in the boss 120.
  • the wedge 136 acts as a stop to halt the rotation of the fork 68 on the head 12, which will be explained herein.
  • the pivot locking mechanism 80 includes a rotatable knob 142 and a sliding cam plate 144.
  • the rotatable knob 142 includes an offset receiving portion 143 to retain the knob 142 onto the pivot 124.
  • the knob 142 includes an eccentric cam surface 146.
  • the cam surface 146 abuts against a tab 148 of the sliding cam plate 144.
  • the cam plate 144 includes a tab 145 which retains a plurality of pins 150 which mate in the recesses 134 of the head locking gear 130.
  • the pins 150 are loaded by springs 152, which are retained in a housing portion 154 of the fork 68.
  • a plate 155 secures the sliding cam plate 144 in the housing portion 154.
  • the housing portion 154 includes an arcuate portion 156 and a rectangular portion 158.
  • the arcuate portion 156 fits around the cylindrical boss 120 enabling the fork 68 to rotate about the boss 120.
  • the arcuate portion 156 has ends 160 and 161 which act as stops and abut the wedge 136 stopping rotation of the fork 68.
  • the wedge 136 acts as a stop to limit the rotation in both directions of the fork 68 (see Figure 7).
  • the sliding cam plate 144, with pins 150 biased by springs 152, are positioned in the rectangular portion 158 of the housing 154. As the knob 142 is rotated, with eccentric cam surface 146 abutting against tab 148, the sliding cam plate 144, as well as pins 150, is moved in the housing portion 158.
  • This movement removes the pins 150 from the recesses 134 of the head locking gear 130.
  • the knob 142 is rotated in a reverse direction to enable the pins 150 to engage different recesses 134 in the head locking gear 130 to lock the fork 68 in a different position with respect to the head 12.
  • the knob 142 is rotated, which, in turn, moves the sliding cam plate 144, as well as pins 150, away from the head locking gear 130 out of engagement with recesses 134.
  • the pins 150 do not extend into the recesses 134.
  • the fork 68 can rotate until the stops 160 and 161 contact wedge 136 halting the rotation of the fork 68.
  • the head 12 is submersible into a liquid such as water and has a water tight seal. Thus, the head 12 may be placed into a bucket of water or the like when in use.
  • the head 12 includes housing 100 surrounding the motor 64 positioned within the housing 100.
  • a cleaning device such as a brush 102, is secured to a motor shaft 104 of the motor 64.
  • the housing 100 includes passageways 106 to enable the soap and water conduits to pass to the nozzles 74 and 108.
  • the nozzle 108 is coupled with the water conduit 40.
  • the cleaning member 102 includes a retention member 110 which has a circumferential wall 112.
  • the wall 112 defines a bore 114.
  • a circumferential flange 116 is positioned on the interior surface of the bore 114.
  • the circumferential wall includes slots forming sections which, in turn, form fingers 118 to retain the cleaning member 102 onto the motor shaft 104.
  • the wall 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 and nozzle 108.
  • the valve 41 connected with the conduit 40 is open to enable fluid from the hose to pass into the conduit 40. This fluid passes through the conduit 40 through the spiral section and out of nozzle 108.
  • the switch 46 activates the pump 44. This forces air into the hose 62 which, in turn, pressurizes the reservoir 66. As the reservoir 66 pressurizes, cleaning solution in the reservoir is passed through hose 72 and out of nozzle 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.
  • a cleaning device 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.
