MICHAEL GIBELLINA 'ATTORNEYS POOL CLEANING DEVICE The present invention pertains to pool cleaning systems and more particularly to a pool cleaning device for directing a spray of water against the side of the pool adjacent the water line while transporting pool cleaning hoses that are free to whip while directing streams of water therefrom in a well known manner.
It has long been known that flexible hoses provided with water under pressure at one end and suspended in a pool unconnected at the other end may be utilized to randomly spray a stream of water against the side and bottom of the swimming pool to ensure the maintenance of the suspension of particles in the water. The suspension of particles enables the normal pool filtering system to effectively maintain the desired condition of the pool without the otherwise necessary vacuuming operations. However, a variety of cumbersome and complicated schemes have been suggested in the prior art for causing the cleaning hoses to traverse the pool and thus uniformly clean all portions thereof; further, the prior apparatus either inadequately covers the entire pool or frequently stalls and entirely fails to transport the cleaning hoses.
In addition to the above difficulties many of the prior art devices neglect the sides of the pool in the vicinity of the water line.
It is therefore an object of the present invention to provide a pool cleaning device for transporting cleaning hoses about the pool.
It is also an object of the present invention to provide a pool cleaning device that is self-propelled and follows the contour of the pool water line to ensure proper cleaning of the entire pool.
It is still another object of the present invention to provide a pool cleaning device having a means of directing a stream of water at the pool side adjacent the water line to dislodge dirt and sediment that may otherwise collect.
These and other objects of the present invention will become more readily available as the description proceeds.
Briefly, in accordance with a chosen embodiment of the invention a circular floating rotatable disc or platform is provided with a pair of water-directing nozzles that direct water out from the platform with a velocity tangential thereto to cause the platform to rotate about a vertical axis. An inflexible supply conduit communicates with the nozzles at the axis of rotation of the platform and extends downwardly and horizontally therefrom. The end of the inflexible supply conduit remote from the floating platform includes a water jet or nozzle for generating a thrust and urging the inflexible conduit and platform into contact with the pool side. The inflexible supply conduit includes an offset between the ends thereof so that the line of thrust does not pass through the vertical axis of rotation of the platform. A second inflexible supply conduit is connected to the first conduit intermediate the ends thereof at an angle of less than 45. A flexible supply conduit or hose is connected to a source of water under pressure and to the second inflexible supply conduit. A plurality of cleaning hoses are spaced along and connected to the flexible conduit and depend therefrom to provide a random whipping action to clean the bottom and sides of the pool below the water line.
The present invention may more readily be described by reference to the accompanying drawings, in which:
FIG. 1 is a top view of a portion of a swimming pool incorporating the pool cleaning apparatus of the present invention.
FIG. 2 is a cross-sectional view of FIG. 1 taken along line 2-2.
FIG. 3 is a perspective view of a pool cleaning apparatus constructed in accordance with the teachings of the present invention.
FIG. 4 is a top view of the apparatus of FIG. 3.
FIG. 5 is a cross-sectional view of a portion of FIG. 3 taken along line 5-5.
In referring now to the drawings a swimming pool 10 includes side walls 11 and bottom 12 which are to be cleaned by the system of the present invention. A plurality of cleaning hoses 13 are supported from a flexible conduit 15 which is connected to a suitable source of water under pressure (not shown) such as the pool recirculating pump. The cleaning hoses 13 direct jets of water therefrom and consequently whip to randomly direct these jets against the bottom and sides in a manner well known in the art. The flexible conduit 15 supplies water through inflexible conduit 17 to inflexible conduit 18. It may be noted that the former is provided with a float 21 to help support the cleaning hose and flexible conduit 15. The conduit 18 includes at one end thereof a small opening 23 for directing a stream of water axially thereof thereby producing a thrust indicated by the arrow 25 in FIGS. 1 and 4. The conduit 18 includes an offset 26 such that the direction of thrust 25 does not pass through the vertical axis 28.
A floating rotatable platform 30 is provided and, in the embodiment chosen for illustration, is formed of a circular disc rotatable around the axis 28. The conduit 18 passes up through the platform 30 and is connected to a rotating head 33 that in turn communicates with nozzle 34 and 35. The nozzles are formed to direct water therefrom with a horizontal component of velocity the reaction to which results in the rotation of the platform 30 in the direction indicated by the arrow 38. An upper platform or disc 32 may be formed around the conduits 34a and 35a, and is fixed to the platform 30 by a spacer 31. The upper platform 32 prevents the device from becoming jammed or entangled in the event the platform 30 attempts to enter an opening such as the skimmer opening 42 provided adjacent the surface 43 of the water 44.
The angle 0 formed by the inflexible conduits l7 and 18 is less than 45 and is preferably approximately 30. It has been found that this angular relationship provides sufficient thrust to force the platform 30 against the side 11 of the pool regardless of the curvature (e.g., the negative curvature of the side of the pool in the area 40 or the sharp corner of the pool in the area 41).
The operation of the device may now be described. Water under pressure flowing in the flexible conduit 15 is admitted to the conduit 18 resulting in a jet of water from the opening 23. The thrust propels the platform against the side of the pool. The water supplied to the conduit 18 is also delivered to the nozzles 34 and 35 causing the platform 30 to rotate; thus, the platform frictionally engages the sides 11 of the pool 10 and walks about the periphery thereof. As the platform 30 rotates and thus moves the platform about the periphery of the pool, the water jets eminating from the nozzles 34 and 35 continuously strike the side of the pool immediately above the water line.
If the platform should strike an object such as the ladder 45 the rotating motion of the platform causes the platform to move out and around the obstruction and back into contact with the pool wall on the opposite side of the obstruction. The interrelationship among the thrust along the inflexible conduit 18, the angle between conduits 17 and 18, and the rotational motion of the platform 30 results in the continuous smooth movement about the periphery of the pool regardless of the curvature or configuration of the pool and regardless of obstructions positioned at the pool side. It has been found that the angular velocity of the platform 30 may be varied within wide limits without significantly affecting the performance of the device, however, the angular relationship between conduits 17 and 18 may be critical such that outside of the limits above described the platform 30 will either not properly follow the contour of the pool and may even follow a circular or spiral path toward the center of the pool without contacting the sides thereof.
The present invention utilizes the motive force of the rotating platform against the pool side to move the flexible conduit about the pool. The device thereby not only continuously moves the cleaning hoses 13 but also continuously cleans the sides of the pool adjacent the water surface. The system of the present invention readily passes over submerged obstruction such as steps since a depth of only a few inches is required beneath the platform practice, it has been found that a depth of only three inches is required to permit the platform to pass. Further, only one moving part is utilized in the entire design.
It will be obvious to those skilled in the art that many modifications can be made without departing from the spirit of the invention; for example, inflexible conduit 17 need not include the float 21 and indeed may be of extremely short length sufficient only to ensure the proper angular relationship between the conduits l7 and 18. It is also obvious that the platform 30 may be constructed in a variety of configurations.
