Description

RELATED APPLICATION

This application is related to application Ser. No. 12/843,624, (our file JHUI1953) filed by co inventor, Wing-kin HUI, for A Power Head for Above Ground Pools, filed on Jul. 26, 2010. This application is specifically incorporated herein and is to be used for any and all purposes consistent with incorporation by reference.

FIELD OF THE INVENTION

This invention generally relates to the field of automated pool products. More particularly, this invention relates to above ground pools having a facility for a return water flow head.

BACKGROUND OF THE INVENTION

In order to properly operate and maintain a pool and its contents, it is necessary to have a variety of electrical appliances. For example, a pool cleaner, which sweeps and cleans the pool water, requires electrical power. Additional electrical appliances, such as salt chlorinator generators and mineral sanitizing devices are used to maintain the proper pH levels in the pool.
Other electrical appliances are used to enhance the usability and the beauty of the swimming pool. For example, pool lights used to illuminate the pool at night to facilitate night swimming are powered by electricity. Additionally, a color wheel may be used as decoration to give the pool the special effects desired by the pool owner. Such a color wheel is likewise an electrical appliance.
Typically, the user now runs electrical lines or cords from the domestic residence to the site of the pool. This naturally would mean that electrical cords are spread out all over the area adjacent the pool. Naturally this is not a desirable condition. This condition is exacerbated when there is more than a single cord from the domestic residence to more than one electrical appliance. The likelihood of someone being injured by tripping on the cords increases exponentially. Obviously this creates a safety hazard and liability issues for the pool owner.
In addition to the likelihood of injury, the beauty and general attractiveness of the user's yard is dramatically and negatively affected by the messiness of having one or more cords lying around. It is quite clearly an unsightly and undesirable condition.
Additionally, each of the cords must be placed in storage after usage. First, the user must lay out the cord and then the user connects the cord to the electrical appliance desired to be used. The cords lay on the ground during usage and then upon completion of device usage, they must be disconnected from the electrical appliance and then stored.
Cleary having to do each of these steps, each and every time an electrical appliance is used becomes tiresome, if not downright tedious. There are certainly better ways for a pool owner to spend his/her time, for example enjoying his/her pool.
What is needed is the ability to exchange one pool appliance with the other easily. This means without have to drain the pool or substantial portions of the pool. Clearly, have to remove and then add water after draining is both expensive and time consuming.
Ideally, what is sought is the ability to make the exchange of one appliance for another without affecting the level of the pool in any way. This may mean that the exchange would need to take place underwater. Quick clearly, a new design for interconnection between pool power head and pool appliance would be required.
What is needed is a structure that allows the above ground pool user the ability to easily and efficiently connect one or more electrical appliances to a pool power head without affecting the level of the water. The exchange must be able to be made quickly and simply without requiring a pool owner to completely redesign his pool or his pool appliances.
