Brief Patent Description - Full Patent Description - Patent Application Claims
Not Applicable Not Applicable 1. Technical Field The present invention generally relates to swimming pools. More particularly, the present invention relates to a prefabricated fiberglass swimming pool and spa combination wherein the spa is wholly disposed within the interior of the prefabricated fiberglass pool shell. 2. Related Art Swimming pools are well known in the art. Prefabricated swimming pools have increased in popularity, and it is common to see a backyard swimming pool for recreation in family home. To that end, swimming pools are manufactured in various shapes and sizes. There are numerous types of pools including above-ground pools, vinyl-lined in-ground pools, gunite pools, poured-concrete pools and fiberglass pools. Prefabricated fiberglass swimming pools generally consist of molded, one piece structures that rest within an excavated portion of ground, the latter defining an excavated floor that is compacted, typically with sand and water, and graded to the contours of the pool. Typically, once set into place the fiberglass pool is filled with water while construction sand is water-compacted around the outside of the pool to lock the pool into position. Thereafter, a coping is formed on the outer periphery of the pool and electrical connections and plumbing for heating and filtering is installed. Advantageously, fiberglass pools have the ability to flex without loosing strength, which is especially important in areas where the ground may have a tendency to shift. Moreover, fiberglass pools are approximately seventeen times stronger than concrete, with a tensile strength of approximately 11,300 pounds per square inch. As a consequence, such flexibility allows the pool to expand and contract with the earth without being damaged. Moreover, because the tile trim affixed about the periphery of the pool is typically secured via a silicone adhesive silicone grout, such tile will also flex with the pool and thus remain more durably attached, unlike tile trim affixed to conventional concrete pools. Moreover, because silicone grout is utilized, the same is thus impervious to stains and algae growth. In fact, it is well-documented that the installation of a fiberglass pool is substantially easier and less time consuming versus the time it takes to construct and outfit a conventional concrete pool. Exemplary of such fiberglass pools include those pools produced by San Juan Products, Inc. of Lakeland, Fla. and displayed via its website, http://sanjuanpools.com. Also well known in the art are integrated swimming pool/spa combinations. There is a multitude of swimming pool and spa integrated systems and designs. Usually, the spa is disposed outside the wall of the swimming pool. The spa may also be attached to the swimming pool. Some designs of integrated pool/spa combinations share a common wall or boundary. For example, the spa may be disposed within the pool; however the periphery of the pool wall shares at least one common wall with the spa. Other pool and spa combinations do not include the spa disposed within the swimming pool; rather the spa may share a common wall or boundary with the pool wall at same section along the periphery of the pool. The pool/spa integrated system is designed to have the appearance that the spa is built into the swimming pool and in some designs the spa is in fact built-in. Typically, the spa area of the pool and spa integrated system is located in a corner of the pool or adjacent to the periphery of the pool. Despite the numerous designs of swimming pools and spas and combinations thereof, there are no swimming pool and spa combinations wherein the spa is disposed within the swimming pool such that the spa is completely circumscribed by the boundaries or the periphery of the pool wall. In other words, there are no integrated pool and spa combinations wherein the spa is surrounded by the pool and the pool boundary does not share a common boundary with the spa. Additionally, there are no integrated fiberglass pool and spa combinations that are generally a molded one piece structure wherein the spa is disposed within the pool boundary such that it appears as an island within the pool. Along these lines, by virtue of the manufacturing process for forming fiberglass pools, such structures would necessarily have to be integrated as part of the molding process, which as a consequence would substantially complicate and add to the cost associated with manufacturing fiberglass pools. As such, consumers are often limited as to what additional options they can incorporate as part of their fiberglass pools, and thus cannot incorporate a spa within the pool that shares no common boundary with the pool. In this regard, there is typically no way to easily incorporate such structures without permanently affixing such structures in or around the swimming pool. Accordingly, there is a substantial need in the art for a prefabricated pool and spa combination wherein the spa is surrounded by the pool and shares no common boundary with the pool regardless of its construction type (i.e., whether fabricated from concrete or fiberglass). There is likewise a need in the art for such an integrated pool and spa consists of a molded one piece pre-formed structure or shell. There is additionally a need in the art for such a system that is of exceedingly simple construction, exceptionally durable, and can provide substantial options to pool purchasers while minimizing complications associated with the fiberglass pool manufacturing process. The present invention specifically addresses and alleviates the above-identified deficiencies in the art. In this regard, the present invention is directed to a prefabricated swimming pool and spa combination for in-ground installation and use. The integrated pool and spa combination comprises a swimming pool that has a contiguous vertical perimeter pool wall. The pool wall forms the periphery or boundary of the swimming pool. Additionally, the pool wall may be thought of as forming the swimming pool enclosure. The swimming pool also has a bottom surface. The bottom surface is engaged to the pool wall. The bottom surface of the swimming pool and the pool wall form the shape of the pool. The present invention also includes a spa integrated within the swimming pool. In particular, the spa is disposed within the swimming pool. The spa is circumscribed by the pool wall. The spa includes a contiguous vertical perimeter spa wall. The spa wall forms the spa enclosure. The spa wall is engaged to the bottom surface of the swimming pool. The spa is engaged in a way such that the pool wall has no common boundary with the spa wall. The present invention may also include a swimming pool that has a portion of the bottom surface depressed. The depressed portion is capable of receiving a spa structure. The spa wall is engageable with the depressed portion of the bottom surface. In another embodiment of the present invention, it is envisioned that the prefabricated swimming pool and spa combination includes a contiguous stairway formed from the pool to the spa. The stairway is integrally located within the pool for egress and ingress from the pool to the spa or vice versa. In a preferred embodiment of the present invention the prefabricated pool and spa molded one piece structure is manufactured such that the electrical connections and plumbing for the heating and filtering of the pool and spa combination are shared. One aspect of the present invention contemplates using a ramp to connect the pool wall to the spa wall. The prefabricated swimming pool and spa combination may also include steps for ingress or egress to the pool and/or the spa. In a preferred embodiment of the present invention the material used to construct the prefabricated pool/spa is comprised of fiberglass. These as well as other features of the present invention will become more apparent upon reference to the drawings. Continue reading about Prefabricated swimming pool and spa combination...
