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 box used to house an automatic pool cover.




2. Description of the Related Art




Swimming pools are commonly covered to prevent debris from entering the pool and to heat the pool in the case of a solar cover. An automatic pool cover provides convenience for a user by allowing the cover to be easily extended over the pool during periods of non-use, and retracted during periods of use. Typically, a box is placed in the decking surrounding the pool at a location opposite from the walk-in steps (usually at the deep end of a pool). The box extends across the width of the pool, and houses an electric motor and reel on which the cover is wound.




A problem with conventional automatic pool cover boxes is that they are typically constructed from treated lumber and manufactured on-site at the pool location. The box is usually constructed from treated 2×12's which are coupled together in an end-to-end manner corresponding to the width of the pool and additional space at each longitudinal end required for the drive motor and mounting brackets. For example, a swimming pool having a width of 20 feet typically requires a automatic pool cover box of about 26 feet in length. To prevent deflection of the 2×12 walls relative to each other, cross members in the form of 2×4's or the like are fastened to the 2×12 side walls at period locations along the length of the box. It will be appreciated that the weight of a box constructed primarily from 2×12's which is 26 feet long is very heavy. Moreover, depending upon the skill of the installers, the quality of the box may vary from one installation to another.




What is needed in the art is an automatic pool cover box which is easy to assembly on-site, provides uniformity of construction from one installation to another, is light weight, and adjustable.




SUMMARY OF THE INVENTION




The present invention provides an automatic pool cover box having a front wall, rear wall and lid constructed from modular components which may be easily connected together on-site and adjusted relative to each other to provide an optimum installation.




The invention comprises, in one form thereof, an automatic pool cover box including a front wall having a plurality of elongated extrusions, each extrusion having a first side wall, an opposite second side wall, a first coupler on the first side wall and a second coupler on the second side wall. Adjacent extrusions are coupled together using a respective first coupler and second coupler. A second side wall of one of the extrusions defines a bottom edge of the front wall. A rear wall includes a plurality of elongated extrusions, each extrusion having a first side wall, an opposite second side wall, a first coupler on the first side wall and a second coupler on the second side wall. Adjacent extrusions are coupled together using a respective first coupler and second coupler. A second side wall of one of the extrusions defines a bottom edge of the rear wall which is at least intermittently connected with the bottom edge of the front wall. A lid includes a plurality of elongated extrusions, with each extrusion having a first side wall, an opposite second side wall, a first coupler on the first side wall and a second coupler on the second side wall. Adjacent extrusions are coupled together using a respective first coupler and second coupler. A hinge member interconnects the rear wall and the lid. The hinge member is coupled with the rear wall in a vertically adjustable manner and is hingably coupled with the lid.




An advantage of the present invention is that the automatic pool cover box is constructed from substantially identical extrusions, thereby reducing the part count of different types of parts.




Another advantage is that the box may be easily assembled on-site, without substantial variance from one installation to another.




Yet another advantage is that the lid may be adjusted in a vertical manner relative to the rear wall, thereby providing optimum fit and slope to the lid.




A further advantage is that a wear bar may be attached to the top edge of the front wall to inhibit wear of the cover during extension and retraction.




Still another advantage is that a coping may be directly carried by the lid.




Another advantage is that the leading edge bar may include a coping with a leading edge which is substantially the same as the remaining coping of the pool, and a trailing edge which mates with the coping carried by the lid.




Yet another advantage is that the box is very light weight when compared with conventional designs.

.




Leading edge bar


16


includes a coping


90


which extends upwardly therefrom. Coping


90


includes a leading edge


92


and a trailing edge


94


. Leading edge


92


has a shape which is substantially the same as coping


86


. Thus, when leading edge bar


16


is positioned against coping


86


as shown in

FIG. 1

, leading edge


92


has the effect of merely replacing coping


86


. Trailing edge


94


has a shape which is complimentary to coping


86


. Thus, when leading edge bar


16


is against coping


86


as shown in

FIG. 1

, trailing edge


94


of coping


90


substantially conforms to the shape of coping


86


, thereby preventing downward deflection of coping


90


while cover


14


is in the open position as shown.




Wear bar


96


is connected with first coupler


40


of extrusion


32


. Wear bar


96


extends substantially across the length of extrusion


32


(in a direction perpendicular to the drawing of

FIG. 1

) and provides a smooth surface over which cover


14


may slide when being extended and retracted. In the embodiment shown, wear bar


96


has a substantially semi-circular shape with a smooth outer periphery. Wear bar


96


may be coated with a low friction material such as Teflon®, etc. to allow easier sliding and inhibit wear of cover


14


during extension and retraction thereof.




In the embodiment shown in

FIG. 1

, extrusions


32


,


34


of front wall


26


, extrusions


44


,


46


of rear wall


28


, and extrusions


68


,


70


of lid


30


are all substantially identical to each other. However, it is to be understood that front wall


26


, rear wall


28


and/or lid


30


may include one or more extrusions which are differently configured. For simplicity and reduction of parts count, however, extrusions


32


,


34


,


44


,


46


,


68


and


70


are preferably all configured substantially identical.




Referring now to

FIG. 3

, there is shown another embodiment of a lid


100


which may be utilized with an automatic pool cover box of the present invention. Lid


100


also includes two extruded aluminum pieces which couple together, similar to lid


30


shown in FIG.


1


. More particularly, lid


100


includes a first extrusion


102


, a second extrusion


104


, a hinge member


106


and a coping


108


.




Hinge member


106


includes an L-shaped lower portion


110


which rests on top of the rear wall of the cover box (not shown). Lower portion


110


may be fastened to the top of the rear wall using suitable fasteners, such as self-tapping screws. Leg


112


and downwardly depending flange


114


allow interconnection with a concrete deck (not shown) poured against hinge member


106


. Hinge


116


provides pivotal attachment with second extrusion


104


.




Second extrusion


104


includes rearward C-shaped portion


118


which rests on and provides pivotal movement relative to hinge


116


. Male projection


120


of second extrusion


104


and female recess


122


of first extrusion


102


allow interconnection between first extrusion


102


and second extrusion


104


. Projection


120


and recess


122


are configured such that interference therebetween occurs when first extrusion


102


and second extrusion


104


are disposed generally parallel to each other as shown in FIG.


3


. First extrusion


102


and second extrusion


104


will not deflect further in a downward direction relative to each other, but can be in essence hinged about projection


120


and recess


122


in an upward direction to allow lid


100


to be disassembled or to allow lid


100


to be removed from the cover box.




Coping


108


includes male projections


124


which mate with corresponding male projections


126


of first extrusion


102


. The top projection


126


of first extrusion


102


has a thinned section near the distal end thereof allowing lateral flexure for interconnection with projections


124


without permanent deformation thereof. Each of projections


124


and projections


126


include a beveled mating face such that a transverse force component is applied to each of projections


126


upon insertion of projections


124


of coping


108


. Coping


108


also includes a fiber optic slot


128


for receiving a fiber optic cable (not shown) surrounding the swimming pool. A pair of lower male projections


130


allow interconnection with an optional structural support (not shown) extending across the width of the automatic cover box to provide further structural support to lid


100


and thereby prevent downward deflection thereof. The particular configuration of the additional structural support may vary, depending upon the strength requirements for the particular application.




While this invention has been described as having a preferred design, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
