The present invention generally relates to a cover for a pool, and more specifically to a protective cover configured to keep debris out of the pool when in place. Accordingly, the present specification makes specific reference thereto. However, it is to be appreciated that aspects of the present invention are also equally amenable to other like applications, devices and methods of manufacture.
A swimming pool is a structure designed to hold water to enable swimming or other water based leisure activities. Pools can be built into the ground, in-ground pools, or built above ground as a freestanding construction or as part of a building or other larger structure. Swimming pools are popular as an affordable luxury that enable many people to enjoy water based activities in the comport of their own homes. A hot tub or spa is a similar structure used to retain water for recreational purposes.
Taking care of a pool can be a frustrating, difficult and time consuming task. Pools require regular maintenance as they are easily contaminated. Swimming pool contaminants are introduced from environmental sources and swimmers. Environmental contaminants affecting outdoor swimming pools include windblown dirt and debris, incoming water from unsanitary sources, rain containing microscopic algae spores, and bird droppings that can harbor disease-causing pathogens. A well-maintained, properly operating pool filtration and re-circulation system is the first barrier in combating contaminants large enough to be filtered.
Filtration is a physical operation that separates solid matter and fluid from a mixture with a filter medium that has a complex structure through which only the fluid can pass. Solid particles that cannot pass through the filter medium are described as oversize. Oversize particles may form a filter cake on top of the filter and may also block the filter lattice, preventing the fluid phase from crossing the filter. The size of the largest particles that can successfully pass through a filter is called the effective pore size of that filter.
To properly filter or remove solid contaminates a swimming pool, there is a choice of manually cleaning the pool or using an automated pool cleaner. An automated pool cleaner is a vacuum-type cleaner that is designed to collect debris and sediment from the surface of swimming pools with minimal human intervention. Alternatively, a skimmer or a leaf net, along with an extendable telescoping pole, may be used to manually rake and collect the leaves and debris from a pool.
Pool covers provide a proactive way to protect a pool or hot tub from debris. Pool covers can also significantly decrease pool heating costs and reduce the amount of chemicals required by the pool. Outdoor pools gain heat from the sun, absorbing much of the solar energy striking the pool surface. Though a cover decreases the total amount of solar heat absorbed by the pool, the cover eliminates heat loss due to evaporation and reduces heat loss at night through its insulating properties. Most swimming pool heat loss is through evaporation. Unfortunately, debris commonly makes its way into pools despite covers or other physical barriers, During winter, snow and ice can weigh down these barriers and covers letting debris and rainwater enter and contaminate the water.
Therefore, there exists a long felt need in the art for an improved cover to protect a pool. There is also a long felt need for a device that saves extensive time and effort in maintaining a pool or a hot tub. Additionally, there is a long felt need in the art for a pool cover that can keep leaves, insects, dirt, rainwater, and other debris or contaminates out of a pool during nonuse. There is also a long felt need in the art for a pool cover that prevents the accumulation of snow and ice during the winter. Finally, there is a long felt need in the art for a pool cover that protects the pool water eliminating the need to manually skim or vacuum the pool.
In this manner, the improved protective pool cover of the present invention accomplishes all of the forgoing objectives, thereby providing an easy solution keeping a pool or hot tub clean from debris. A primary feature of the present invention is a pool cover configured to avoid the buildup of snow and ice during the winter. Finally, the improved protective pool cover of the present invention is capable of keeping external debris and contaminates out of the pool by diverting the debris and contaminates away from the pool.
