Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to swimming pools, and, more particularly, to an automatic pool cover assembly for use in a swimming pool.




2. Description of the Related Art




A swimming pool generally includes a plurality of upright perimeter walls which surround a pool adjacent to the deck area of the pool. The walls may be construed from metal, plastic or concrete. In the case of plastic or metal walls, it is common to hang a vinyl liner from a coping which surrounds the perimeter of the pool at the top of the perimeter walls. It is also common to cover a swimming pool to prevent dirt, debris, etc. from entering the pool. The cover may be manually extended and retracted over the pool, or may be automatically extended and retracted over the pool.




In the case of an automatic pool cover, a track is typically mounted at the top of opposite side walls of the pool. The track may either be fastened directly to the deck above the side walls, or may be incorporated into the coping at the top of the side walls. A pool cover box is positioned at an end of the pool, typically opposite from the walk-in steps at the deep end of the pool. The automatic cover is wound around a reel contained within the cover box. The cover has a rope which is sewn into the opposite side edges, thereby forming a bead along the opposite side edges. Each bead is retained with a corresponding track at the top of the generally parallel side walls. An electric motor coupled with the reel and the ropes selectively moves the cover to a closed or opened position.




To maintain the cover at a position above the pool as the cover is being moved from the opened to the closed position, or vice versa, a leading edge bar is typically attached to the leading edge of the cover. The leading edge bar extends the width of the pool and is attached to the leading edge of the cover. Typically, the leading edge of the cover is simply sewn to form a loop through which the generally cylindrical leading edge bar extends.




Although sufficient to move the cover from the opened to the closed position, or vice versa, it is possible to permanently deflect the leading edge bar in a downward direction when the leading edge bar is at the opened or closed positions. Moreover, the leading edge bar is easily discernable from the other components of the pool when at either the opened or closed positions.




What is needed in the art is a leading edge bar which is not deflectible to an appreciable extent in a downward direction at either the opened or closed positions, and which is more aesthetically appealing.




SUMMARY OF THE INVENTION




The present invention provides a swimming pool including a leading edge bar which locks in place and is prevented from downward deflection when at the fully opened or fully closed positions.




The invention comprises, in one form thereof, a swimming pool including a first end wall, a second end wall and a pair of side walls. A cover box is positioned adjacent to the first end wall. A coping is positioned at the top of the side walls and the second end wall. The coping includes a cover track slot. A leading edge bar is associated with the cover track slot and is movable between positions adjacent a first end wall and a second end wall. The leading edge bar includes a nose which fits into the cover track slot of the second end wall when the leading edge bar is adjacent to the second end wall.




The invention comprises, in another form thereof, a swimming pool including a first end wall, a second end wall and a pair of side walls. A cover box is positioned adjacent to the first end wall. A coping is associated with the first end wall, the second end wall and the pair of side walls. A leading edge bar is movable between positions adjacent to the first end wall and the second end wall. The leading edge bar includes a rearwardly facing wall having a shape which is complimentary to and mates with the coping above the first end wall when the leading edge bar is adjacent to the first end wall.




An advantage of the present invention is that deflection of the leading edge bar is prevented when the leading edge bar is at the fully opened or fully closed position.




Another advantage is that the leading edge bar is provided with a rearwardly extending flange which acts as a guide surface as the leading edge bar approaches the coping when moved to the fully opened position.




Yet another advantage is that the leading edge bar may be provided with a bumper which absorbs shock and seals the leading edge bar relative to the coping when at the fully closed position.




A still further advantage is that the leading edge bar may be provided with a shape which is generally the same as the coping.

DETAILED DESCRIPTION OF THE INVENTION




Referring now to the drawings, there is shown a portion of an embodiment of a swimming pool


10


of the present invention. Swimming pool


10


generally includes a first end wall


12


, a second end wall


14


, a pair of side walls


16


, a cover box


18


, a coping


20


, a leading edge bar


22


and a cover


24


. First end wall


12


, second end wall


14


and side walls


16


surround swimming pool


10


. Coping


20


is positioned at the top of side walls


16


and second end wall


14


. Coping


20


includes a facia


26


, fiber optic light slot


28


and cover track slot


30


. Facia


26


may have any suitable curvature, and in the embodiment has a compound curvature. Fiber optic slot


28


is positioned within facia


26


above cover track slot


30


. Fiber optic slot


28


receives a fiber optic light tube (not shown) therein which surrounds swimming pool


10


. Cover track slot


30


receives a cover track


32


therein along each side wall


16


(FIG.


4


). Cover track slot


30


remains empty (i.e., does not contain cover track


32


therein) on second end wall


14


.




Cover box


18


carries a reel


34


therein, which in turn carries an automatic cover


24


which is used to cover swimming pool


10


, as will be described hereinafter. Cover box


18


includes a lid


38


positioned over reel


34


. Lid


38


is attached with and carries coping


20


positioned over first end wall


12


. Coping


20


positioned over first end wall


12


is disposed in generally vertical alignment with coping


20


positioned over each side wall


16


such that fiber optic slot


28


is aligned around the entire periphery of swimming pool


10


.




Leading edge bar


22


is slidably carried by the pair of cover tracks


32


associated with each side wall


16


. Leading edge bar


22


is movable between a position adjacent first end wall


12


and second end wall


14


. Leading edge bar


22


is in the form of a “low profile” leading edge bar, and generally includes a nose


40


, front slot


42


, rear slot


44


, bumper


46


and rearwardly extending flange


48


.




Rear slot


44


has a generally circular cross-section, and receives a leading edge


50


of cover


24


therein. More particularly, leading edge


50


of cover


24


has a cord or rope (not numbered) which is sewn therein. The leading edge


50


of cover


24


is then slid in a longitudinal direction within rear slot


44


of leading edge bar


22


. Rearwardly extending flange


48


includes a downwardly turned end (not numbered) which provides a guide surface for coping


20


positioned above first end wall


12


as leading edge bar


22


approaches first end wall


12


. Thus, flange


48


is positioned under coping


20


when leading edge bar


22


is adjacent first end wall


12


as cover


24


is moved to the fully retracted position.




Front slot


42


carries bumper


46


therein. Bumper


46


is preferably formed from an elastomeric material, such as rubber, and abuts facia


26


of coping


20


when leading edge bar


22


and cover


24


are moved to the fully closed positioned over swimming pool


10


. Bumper


46


may have any suitable configuration, and in the embodiment shown has a generally U-shaped configuration with a bead which fits into front slot


42


. Bumper


46


abuts facia


26


of coping


20


over second end wall


14


when leading edge bar


22


is adjacent second end wall


14


. Additionally, nose


40


fits within cover track slot


30


of coping


20


over second end wall


14


when leading edge bar


22


is adjacent second end wall


14


.




End cap coping


52


is attached to the top of first end wall


12


. End cap coping


52


includes a liner bead slot


54


and fastener slot


58


. Liner bead slot


54


receives the bead of a vinyl liner which is hung adjacent the interior wall of first end wall


12


. Fastener slot


58


allows fasteners such as self-tapping screws to be used to fasten end cap coping


52


to the top of first end wall


12


. The heads of each fastener (not shown) are received within fastener slot


58


such that cover


24


does not contact the fastener heads.




During use, leading edge bar


22


and cover


24


are moved to a retracted position over swimming pool


10


by energizing an electric motor (not shown) which is mechanically coupled with reel


34


. Flange


48


acts as a guide surface below coping


20


as leading edge bar


22


moves adjacent to coping


20


positioned over first end wall


12


. When in the fully retracted position, leading edge bar


46


is positioned vertically adjacent end cap coping


52


such that vertical deflection of leading edge bar


22


is prevented. To move leading edge bar


22


and cover


24


to the extended or closed position over swimming pool


10


, the electric motor is again energized to engage a reel (not shown) to which rope


60


carried by each side edge of cover


24


is attached. Rope


60


pulls cover


24


to the closed position, and the leading edge


50


of cover


24


slides leading edge bar


22


along each cover track


32


. When in the closed position, nose


40


fits within cover track slot


30


over second end wall


14


, and bumper


46


abuts facia


26


of coping


20


over second end wall


14


.




Swimming pool


10


of the present invention is configured such that leading edge bar


22


is vertically supported when at either the closed or opened position. Vertical deflection of leading edge bar


22


is thus inhibited when at the closed or opened positions.





FIGS. 5 and 6

illustrate an embodiment of a swimming pool


70


including another embodiment of a leading edge bar


72


of the present invention. Leading edge bar


72


includes a rear slot


74


for retaining a leading edge


50


of cover


24


, similar to rear slot


44


of leading edge bar


22


shown in

FIGS. 1-4

. Leading edge bar


72


may also include an optional nose


76


for engaging cover track slot


30


of an opposite second end wall


14


, similar to nose


40


shown in

FIGS. 1-4

.




Leading edge bar


72


differs from leading edge bar


22


in that it includes a front wall


78


and a rear wall


80


which each approximate the shape of coping


20


surrounding swimming pool


70


. Thus, when leading edge bar


72


is positioned adjacent to coping


20


over first end wall


12


, front wall


78


has the same general shape as coping


20


and thus in essence replaces the appearance of coping


20


. Moveover, rear wall


80


has a shape which mates with coping


20


. The mating engagement between rear wall


80


and coping


20


prevents downward deflection of leading edge bar


72


. Additionally, downward deflection is limited by block


82


of leading edge bar


72


being positioned immediately above end cap coping


52


.
