Description:
BACKGROUND OF THE INVENTION 
       [0001]    This invention relates to pool tile cleaning devices, more specifically, a pool tile cleaning device that is easy to use, may be used underwater and provides a continuous flow of soap during use. 
         [0002]    Currently, in order to thoroughly clean tiles located on one&#39;s pool, such as glazed ceramic tile pieces located in the vertical area of swimming pools, a person usually uses cleanser or cleaning fluid and a scrub brush attached to an elongated pole to scrub debris off of the tiles. As the cleanser/cleaning fluid is used up, the more difficult it becomes to thoroughly clean the tiles as the person cleaning the tiles must apply greater physical strength to the brush to compensate for the diminishing amount of cleanser/cleaning fluid. Thus, not only is it a difficult and tedious chore to scrub the tiles themselves, but the need to constantly reapply cleanser/cleaning fluid to the brush is required. However, the need to constantly reapply the cleanser/cleaning fluid is time-consuming as one must interrupt his or her cleaning stride, apply more cleanser/cleaning fluid to the scrub brush and return to the cleaning location and continue scrubbing. 
         [0003]    In addition, because liquid soap readily disperses when the scrub brush is inserted into the water, many individuals are currently combining muriatic acid with soap to form a gel that will adhere better to the scrub brush. However, this is an unsafe practice. 
         [0004]    Although there are some devices for cleaning pool tiles, none are effective in providing a continuous distribution of cleanser or cleaning fluid. 
         [0005]    Thus, the need exists for a pool tile cleaning device which thoroughly cleans tiles and provides a continuous and uniform distribution of cleanser or cleaning fluid.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0025]    For purposes of describing the preferred embodiment, the terminology used in reference to the numbered components in the drawings is as follows:
         1 . pool tile cleaning device     2 . handle     3 . cleaning head     4 . water hose     5 . scrubbing means     6 . cleaning product pathway     7 . cleaning head first section     8 . cleaning head second section     9 . support device     10 . purge valve     11 . threads     12 . purge valve top cap     13 . plate     14 . purge valve bottom cap     15 . rod     16 . spring     17 . metering valve     18 . aperture     19 . handle proximal end     20 . handle distal end     21 . pool tile     22 . flow reducer     23 . water     24 . pool edge     25 . reservoir       
 
         [0051]    With reference to  FIG. 1 , a side plan view of the present invention  4  is shown. The pool tile cleaning device  1  includes an elongated handle  2  having a distal end  21  that is attachable to a cleaning head  3  and a proximal end  20  that is preferably attachable to a purge valve  10 . Because the handle  2  is hollow, a reservoir  25  is created for holding cleanser/cleaning fluid that is to be used when cleaning pool tiles. A cleaning product pathway  6  connects the handle  2  to the cleaning head  3  so as to permit the cleaning product to be distributed onto the cleaning head  3 . A metering valve  17  is located on the distal end of the handle  20 , behind the cleaning head  3 , so as to permit a user to control the amount of cleanser/cleaning fluid that is exited from the handle  2  and distributed onto the cleaning head  3 . The purge valve  10  is secured to the handle proximal end  19  and permits air to enter the reservoir  25  when depressed to replace the amount of cleanser/cleaning fluid that is distributed onto the cleaning head  3 . Because the handle  2  is long, a user need not get onto his/her hands and knees in order to clean the pool tiles. He or she may stand upright or slightly hunched over the pool and place the cleaning head  3  such that it is flush against the pool tiles to be cleaned and move the pool tile cleaning device  1  in an up and down, side to side motion. Because the pool tile cleaning device  1  is gravity-fed, meaning that the cleanser/cleaning fluid will naturally flow towards the cleaning head  3  during use, the operator may transport the pool tile cleaning device  1  in a position such that the cleaning head  3  is above the handle  2  without the cleanser/cleaning fluid exiting the pool tile cleaning device  1 . Thus, so long as the metering valve  17  is at least partially open, cleanser/cleaning fluid will flow onto the cleaning head  3  when the reservoir  25  is located above the cleaning head  3 . As the cleanser/cleaning fluid is depleted, the flow will decrease and the user can maintain the desire cleanser/cleaning fluid flow by adjusting the metering valve  17 . 
         [0052]    Next,  FIG. 2  shows a perspective view of a cleaning head  3  of the present invention. The cleaning head  3  includes a support device  9 , a cleaning head first section  7 , a cleaning head second section  8  and a scrubbing means  5 . The support device  9  secures the cleaning head  3  to the handle  2 . The support device  9  may provide for a stationary or pivoting cleaning head  3  so as to permit a user to utilize the present invention at various angles. The cleaning head first section  7  is preferably made of a rigid material, preferably plastic, so as to provide a sturdy base for the cleaning head second section  8 . The cleaning head second section  8  is preferably made of a somewhat flexible material, such as foam, so as to allow for some flexibility while the pool tile cleaning device is in use. The scrubbing means  5 , which is preferably a scrubbing pad which is replaced once a month, allows for the removal of dirt and grime from the pool tiles. Although a scrubbing pad is shown as the scrubbing means  5 , various other materials, which may be rigid or flexible, such as bristles, may also be used. 
         [0053]      FIG. 3  shows a front view of the cleaning head  3  of the present invention. The cleaning product pathway  6  ends on the cleaning head  3  such that the cleaning product/water solution is distributed onto the cleaning head  3 . Because the user will be moving the pool; tile cleaning device  1 , the cleaning product will be spread over the pool tiles. In addition, because the cleaning product is distributed directly onto the cleaning head  3 , the cleaning product is not wasted. 
         [0054]    In  FIG. 4 , a cross-sectional view along line  4 - 4  of the embodiment of  FIG. 1  of a purge valve  10  of the present invention is shown. The purge valve  10  is connected to the handle  2  so as to permit air to enter the reservoir  25  as cleanser/cleaning fluid is deposited onto the cleaning head  3 . When the purge valve top cap  12  is pressed, the purge valve top cap  12  will become adjacent to a centrally-located plate  13 , thereby permitting air to enter the reservoir  25 . The purge valve  10  includes a rod  16  and spring  15  that permit the purge valve top cap  12  and purge valve bottom cap  14  to return to the original starting position when the purge valve top cap  12  is no longer pressed. In addition, the purge valve  10  includes internal threads  11  on either end that allow for the connection of a handle  2  and water hose  4 . 
         [0055]    In order to clean the reservoir  25 , a water hose  4  is secured to the purge valve  10 . When the water faucet connected to the water hose  4  is turned on, the water pressure flows through the reservoir  25  so as to remove any excess cleanser/cleaning fluid that may have dried within the reservoir  25 . The purge valve  10  may be constructed of a predetermined material that does not leave marks. 
         [0056]      FIGS. 5 and 6  show varying views the purge valve  10  of the present invention. The purge valve top cap  12  is preferably large in size while the purge valve bottom cap  14  is preferably-smaller in size than the top cap  12 . However, the top cap  12  may also be the same size or smaller than the bottom cap  14 . When using the pool tile cleaning device  1 , the user must depress the purge valve top cap  12  in order to permit air to enter the reservoir  25 , which in turn allows cleanser/cleaning fluid to exit the reservoir  25  onto the cleaning head  3 . 
         [0057]    Next,  FIG. 7  shows a side view of a metering valve  17  of the present invention. The metering valve  17  is designed such that when adjusted, a flow reducer  22  minimizes the amount of solution flow into the cleaning product pathway  6 . 
         [0058]    Finally,  FIG. 8  shows a perspective view of the present invention in use on pool tiles  21 . Because the handle  2  is elongated, a user need not get on his/her hands and knees in order to clean the tiles  21 . He or she may simply remain a safe distance away from the pool edge  24  and place the cleaning head  3  of the pool tile cleaning device  1  against the pool tiles  22  to be cleaned. Because the cleaning product is direct distributed onto the cleaning head  3 , the pool tile cleaning device  1  may be used within or out of the water  23 . 
         [0059]    In addition, a protective sheath may be secured to the handle  2  to reduce deterioration of the pool tile cleaning device  1  and possible damage to the pool edge during use. 
         [0060]    The use of the present invention will allow persons to thoroughly clean pool tiles quickly and easily with minimal amount of physical discomfort and cleaning product waste. 
         [0061]    Although the present invention is preferably used for the cleaning of pool tiles, the present invention may also be used on a variety of other surfaces. 
         [0062]    It is to be understood that while a certain form of the invention is illustrated, it is not to be limited to the specific form or arrangement of parts herein described and shown. It will be apparent to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not be considered limited to what is shown and described in the specification and drawings.
