## Title
Floating pool skimmer

## Abstract

A floating pool skimmer (1) that randomly travels across the surface of a pool to ensure that the entire surface of the water in the pool is cleaned. The floating pool skimmer has an elongated hose (3) that attaches to a conventional fixed pool skimmer, a vacuum inlet and/or a vacuum hose (6) connecting an automatic pool vacuum (2) to a pool pump and filter. A basket (26) held within a main housing (8) strains water and traps debris which is held in the basket by suction from the pool filter while the pool filter is operational. When the pool filter is not running a floating weir (17) and/or one or more weir doors (30) prevents debris from floating back out of the basket and into the pool. Apertures (14) located on the main housing allow water into the main housing that then acts as a ballast to ensure the floating pool skimmer remains upright at all times.

## Background
FIELD OF THE INVENTION
This invention relates to pool maintenance and more particularly, to an automatic pool skimmer that floats on the surface of a pool to ensure that the entire surface of the water in the pool is cleaned.
BACKGROUND OF THE INVENTION
Conventional pool skimmers are typically fixed housings located adjacent to a pool wall in a pool deck. Pool water is drawn from the pool via a rectangular aperture located in the pool wall. The housing may be accessed from the pool deck through a circular or rectangular lid. When a pool pump is operational water is drawn from the pool through the aperture in the pool wall over a weir. Then, the water is drawn down into a removable skimmer basket (the purpose of which is to entrap leaves and other floating debris) and circulated via pipes to the pool pump through a filter and finally back into the pool through one or more outlets located in the pool wall. A problem with fixed skimmers is that they are only able to trap and remove debris from the surface of the pool water when the debris moves close to the pool skimmers to be sucked into the housing and into the skimmer basket. Therefore, a large portion the pool surface is not cleaned. An additional problem arises when a pool only has one fixed skimmer and an automatic vacuum device is connected to the skimmer. In this situation the automatic vacuum device is attached to and powered by the skimmer, thus the skimmer is not cleaning the surface of the pool water but rather supplying suction to the automatic vacuum device, which only cleans the pool floor.
There are currently mobile floating skimmers available, however these types of skimmers pose many problems. One problem experienced with existing mobile skimmers is that they are unstable and have a tendency to tip over especially when not operating as there is no suction from the pool pump pulling the skimmer downward to act as a ballast, thereby keeping the skimmer in an upright position. An additional problem also occurs when the pump is turned off and/or is not receiving suction from the pool pump. When this occurs debris caught in the skimmer can float up and out of the skimmer back into the pool, thereby defeating the purpose of the skimmer.
Therefore, a need exists for a floating pool skimmer that captures and traps debris even when not operating, remains in an upright position at all times and attaches to an existing fixed skimmer, a vacuum inlet and/or an automatic vacuum line.

SUMMARY OF THE INVENTION
The primary object of the present invention is to provide a floating pool skimmer that captures and traps debris from the surface of a pool even when a pool pump is not operating and providing suction to the floating pool skimmer.
An additional object of the present invention is to provide a floating pool skimmer that remains in an upright position at all times even when the pool skimmer is not operating.
An additional object of the present invention is to provide a floating pool skimmer that will attach to an existing fixed skimmer, a vacuum inlet and/or an automatic vacuum line so the automatic pool skimmer can be powered by the pool pump.
The present invention fulfills the above and other objects by providing a floating pool skimmer that floats on the surface of the water in a pool and randomly travels across the surface of the pool to ensure that the entire surface of the water is cleaned. The floating skimmer has an elongated hose that attaches to a conventional fixed pool skimmer, a vacuum inlet and/or a vacuum hose connecting an automatic pool vacuum to the pool pump and filter. The elongated hose of the floating pool skimmer may be attached to a vacuum hose using a T-fitting so that suction from the pool filter is supplied to the vacuum and to the floating skimmer simultaneously. A basket held within a main housing catches debris which is held in the basket by suction from the pool filter while the pool filter is operational. When the pool filter is not running a floating weir and/or one or more weir doors prevent debris from floating back out of the basket. Apertures located on the main housing allow water into the main housing that then acts as a ballast to ensure the floating pool skimmer remains upright at all times.
The above and other objects, features and advantages of the present invention should become even more readily apparent to those skilled in the art upon a reading of the following detailed description in conjunction with the drawings wherein there is shown and described illustrative embodiments of the invention.

With reference to FIG. 1, a cutaway view of a pool in which a floating pool skimmer 1 of the present invention connected to an automatic pool vacuum 2 is illustrated. The automatic pool skimmer 1 floats on the surface of the water in the pool and randomly travels across the surface of the pool to ensure that the entire surface of the water is cleaned. The floating pool skimmer 1 comprises an elongated hose 3 that attaches to a conventional fixed pool skimmer 4, directly into a vacuum inlet and/or a vacuum hose 6 connecting an automatic pool vacuum 2 to the vacuum fixed pool skimmer 4. As illustrated here, the elongated hose 3 of the floating pool skimmer 1 is attached to the vacuum hose 6 with a T-fitting 7 so that suction from the fixed pool skimmer 4 is supplied to the automatic pool vacuum 2 and to the floating pool skimmer 1 simultaneously, thereby allowing the floating pool skimmer 1 and automatic pool vacuum 2 to operate at the same time from a single source of suction provided by a pool pump.
With reference to FIGS. 2-5, a perspective side view of the floating pool skimmer 1 of the present invention, a side view of the floating pool skimmer 1 having a floating weir 17 in a downward position, a side view of the floating pool skimmer 1 having a floating weir 17 in an upward position, and a cross-sectional view along line 5-5 of FIG. 3, respectively, are illustrated. The floating pool skimmer 1 comprises a main housing 8 having a cup-like structure with a perimeter wall 9, a bottom surface 10 and an upper edge 11 of the perimeter wall 9. Said upper edge 11 of the perimeter wall 9 surrounds an opening 12 into the interior of the main housing 8. One or more floats 13 extend outward from the main housing 8 proximate to the upper edge 11 of the perimeter wall 9 to support the floating pool skimmer 1 in water and to keep the upper edge 11 of the perimeter wall 9 substantially parallel to the surface of the water. One or more apertures 14 are located on the main housing 8 on the perimeter wall 9 and/or the bottom surface 10, to allow water to flow into the main housing 8 to ensure the main housing 8 remains submerged just below the surface of the water. The main housing 8 further comprises one or more main housing inlets 15 located proximate to the upper edge 11 of the perimeter wall 9 to allow pool water and any debris floating on the surface of the pool water to flow into the main housing 8. The one or more floats 13 have channels 16 that allow water to reach the main housing inlets 15 of the main housing 8.
A floating weir 17 is located within the main housing 8. The floating weir 17 comprises a perimeter wall 18 preferably having substantially the same shape as the perimeter wall 9 of the main housing 8. The perimeter wall 18 of the floating weir. 17 further comprises an inner surface 19, an outer surface 20, an upper edge 21 surrounding an upper opening 22 and a lower edge 23 surrounding a lower opening 24. One or more floating weir inlets 25 are located on the perimeter wall 18 of the floating weir 17 proximate to the upper edge 21. When the floating pool skimmer 1 is operational and suction is supplied to the main housing 8, the floating weir 17 is sucked into the main housing 8 into a downward position, as illustrated in FIG. 3, to allow water to pass through the one or more floating weir inlets 25. A floating means 5 such as a ring of foam, or other floating material is preferably located below the floating weir inlets 25. When the floating pool skimmer 1 is not operational and suction is not being supplied to the main housing 8, the floating weir 17 floats upward partially projecting out of the main housing 8 into an upward position, as illustrated in FIG. 4, so the floating weir inlets 25 are located above the surface of the water to prevent any debris caught within the floating pool skimmer 1 from escaping out of the floating weir inlets 25. As an alternative to weir inlets 25, the height of the perimeter wall 18 of the floating weir 17 may be less than the height of the perimeter wall 9 of the main housing 8 so that when the floating weir 17 is in a downward position, the upper edge 21 of the perimeter wall 18 of the floating weir 17 is located below the main housing inlets 15. As illustrated in FIG. 5, spacers 28 and/or guides 29 may be located between the main housing 8 and the floating weir 17. The spacers 28 and guides 29 center the floating weir 17 within the main housing 8 and also keep the floating weir inlet 25 lined up with the main housing inlet 15 when the floating weir 17 is in a downward position.
A basket 26 is located within the main housing 8 that strains water passing through the floating pool skimmer 1 to capture debris and prevent debris from passing through a coupling 27 located on the bottom surface 10 of the main housing 8 that is attached to the elongated hose 3.
With reference to FIGS. 6-7, a side view of the floating pool skimmer 1 having a weir door 30, and a cross-sectional view along line 7-7 of FIG. 6, respectively, are illustrated. The floating pool skimmer 1 comprises a main housing 8 having a cup-like structure with a perimeter wall 9, a bottom surface 10 and an upper edge 11 of the perimeter wall 9. Said upper edge 11 of the perimeter wall 9 surrounds an opening 12 into the interior of the main housing 8. One or more floats 13 extend outward from the main housing 8 proximate to the upper edge 11 of the perimeter wall 9 to support the floating pool skimmer 1 in water and to keep the upper edge 11 of the perimeter wall 9 substantially parallel to the surface of the water. One or more apertures 14 are located on the main housing 8 on the perimeter wall 9 and/or the bottom surface 10, to allow water to flow into the main housing 8 to ensure the main housing 8 remains submerged just below the surface of the water. The main housing 8 further comprises one or more main housing inlets 15 located proximate to the upper edge 11 of the perimeter wall 9 to allow pool water and any debris floating on the surface of the pool water to flow into the main housing 8. The one or more floats 13 have channels 16 that allow water to reach the main housing inlets 15 of the main housing 8.
A weir door 30 is located on the main housing inlet 15 of the main housing 8. The weir door 30 is attached to the main housing 8 by a hinge 31 or other rotating means that allows the weir door 30 to open inward into the main housing 8 to allow water to pass through the main housing inlet 15 into the main housing 8 when the floating pool skimmer 1 is operational and suction is supplied to the main housing 8. When the floating pool skimmer 1 is not operational and suction is not being supplied to the main housing 8, the weir door 30 returns to an upward position in line with the perimeter wall 9 of the main housing 8 to prevent any debris caught within the floating pool skimmer 1 from escaping out of the main housing inlet 15.
A basket 26 is located within the main housing 8 that strains water passing through the floating pool skimmer 1 to capture debris and prevent debris from passing through a coupling 27 located on the bottom surface 10 of the main housing 8 that is attached to the elongated hose 3. In addition, an inner housing 32 may be located within the basket 26 for the placement and disbursement of chlorine tabs 33 into the pool water.
It is to be understood that while a preferred embodiment 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 to be considered limited to what is shown and described in the specification and drawings.
