Patent Application
20190112827
The present invention relates generally to swimming pool accessories and more particularly to swimming pool covers.
Swimming pool covers are well known in the art and are commonly placed over a swimming pool to prevent environmental debris from falling into and contaminating the water held within the swimming pool.
Most conventional swimming pool covers are manufactured out of a sheet of plastic material which is slightly larger in length and width than the swimming pool over which it is to be disposed. In use, the swimming pool cover is suspended over the desired swimming pool so that the outer periphery of the swimming pool cover rests outside the swimming pool and preferably on a flat surface surrounding the swimming pool, such as the top surface of a pool edge or a deck. The sheet of plastic material is typically maintained in place over the swimming pool by anchors or springs on the outer periphery of the swimming pool or by disposing weighted objects, such as sand bags or water bags, on top of the periphery of the swimming pool cover.
Although widely used in commerce, plastic pool covers of the type described above experience numerous disadvantages.
As a first notable disadvantage, plastic swimming pool covers are typically heavy and bulky, thereby rendering the placement of the swimming pool cover over a swimming pool a time consuming and physically strenuous task. As a consequence, most swimming pool covers are designed to be disposed over a swimming pool for prolonged periods of time, such as an entire winter season, and are not used for frequent (i.e., daily) pool covering applications.
As a second notable disadvantage, plastic swimming pool covers tend to collect large quantities of water over prolonged periods of time. As a consequence, the collected water tends to weigh down the cover, making removal of the cover difficult.
Still another notable disadvantage of alternate swimming pool covers is that they fail to completely seal off the swimming pool to fully prevent small animals, insects and rodents from entering the pool.
Accordingly, alternative types of swimming pool covers have been introduced to prevent environmental debris from falling into the swimming pool contaminating the water in the swimming pool.
In U.S. Pat. No. 6,286,156 to T. Sullivan there is disclosed a swimming pool cover which includes a mesh screen and a multi-piece frame which is mounted on the periphery of the mesh screen.
Another alternative type of swimming pool cover which is well known in the art employs a thin, lightweight, flexible plastic sheet. However, it has been found, that thin plastic sheets tend to become rapidly embrittled by the sun and/or pool chemicals. As a result, the swimming pool cover is prone to tearing, which is undesirable.
Still another alternative type of swimming pool cover which is well known the art employs rows of isolative, buoyant, foam panels which are hinged together at their adjacent ends by hinge means.
Some other U.S. patents of interest include U.S. Pat. No. 5,740,562 to C. J. Nickalo, U.S. Pat. No. 5,067,182 to L. M. Koelsch, U.S. Pat. No. 3,813,704 to D. A. Troiano and U.S. Pat. No. 3,683,428 to L. Morris.
It is an object of this invention to provide a new and improved swimming pool cover.
It is a further object of this invention to provide a swimming pool cover which can be securely disposed over a swimming pool in order to prevent small animals and rodents from entering the pool and environmental debris and insects from falling into and contaminating water in the swimming pool.
It is yet another object of this invention to provide a swimming pool cover as described above which is highly portable.
It is still another object of this invention to provide a swimming pool cover as described above which does not collect water thereon.
It is another object of this invention to provide a swimming pool cover as described above which has a limited number of parts, which is easy to use and which is inexpensive to manufacture.
It is a further object of this invention to provide a swimming pool cover which is easy to install for daily use and remove, during the summer pool season.
It is a further object of this invention to provide a swimming pool cover which can be securely disposed over a swimming pool in order to completely seal off the swimming pool to prevent small animals and rodents from entering the pool and environmental debris and insects from falling into and contaminating water in the swimming pool.
It is still a further object of this invention to provide a swimming pool cover which completely and tightly seals off the swimming pool over which it is placed.
According to one embodiment of this invention there is provided a swimming pool cover for a swimming pool, the swimming pool being surrounded by a flat surface such as a pool deck, the swimming pool cover being sized and shaped to cover the swimming pool and extend over onto the flat surface, the swimming pool cover comprising a mesh screen, a frame fixedly attached to the periphery of the screen, a first strip of material fixedly secured to the swimming pool cover and a second strip of material fixedly secured to the flat surface and wherein the first and second strips of material cooperate to tightly seal the swimming pool cover to the flat surface and wherein the frame is constructed so that it can be easily collapsed into a stack of panels when the swimming pool cover is not in use.
