System and method of making a pool invisible

Abstract

The present invention provides a novel system and method of covering a pool and making the pool invisible. The present system comprises a flat board and at least one lifting device. The board has sufficient size for covering the pool and is made of rigid materials so as to be able to bear heavy weight. The lifting device includes two parts: a movable part and a fixed part. The one part of the lifting device is fixed on the ground or somewhere in a building near the pool, and another part is joined to the covering board. The lifting device can vertically move the horizontal covering board upward or downward and keep the covering board always horizontal. When want to swim, the users only lift up the covering board, and when want to BBQ, they only lower the covering board to cover the pool. Once the covering board reaches the top of the pool wall, the pool becomes hidden and invisible. The users can do some activities and put something on it even on the lifted covering board as on the floor or on the ground. This expands actually their living space.

Description

[0001]This invention uses the transmission of my provisional patent application, No. 62 / 371732, Filed on Aug. 6, 2016.TECHNICAL FIELD[0002]The present invention is related to a home pool, especially to the cover of the pool.BACKGROUND OF THE INVENTION[0003]There are some covers of the pool for sale in the market now. Most of these covers are made of flexible materials such as plastic fabric and canvas. The main function of the cover is to prevent water from evaporating and children and pets from falling into the water. The flexible materials can't bear the heavier weight, and aren't steady enough for the human activities on their surface though some materials are firmer. Some of the pool covers have a driving device such as a winder and a folder that can drive the cover. The driving device can roll up or fold up the flexible cover and enable the cover to move horizontally for opening or closing the pool.[0004]Let us see the use of another kind of equipment being seemingly irrelevant...

AI Technical Summary

Benefits of technology

The present invention is a new system and method for covering a swimming pool that solves several problems. Firstly, the existing flexible cover cannot bear heavy weight, so the present invention uses a covering board of rigid materials that can bear heavy weight like a floor. This allows people to stand, walk, work, and enjoy activities on the pool, like walking and doing bbq. Secondly, the existing flexible cover can only be used when the pool is open, so using the present system and method, even if the yard is small, the pool can be built approximating the backyard in size. Thirdly, the existing flexible cover has to be removed before opening the pool, but the present system and method can always keep the covering board horizontal and enable it to move vertically upward or downward, so it doesn't need to be removed when opening the pool. Fourthly, the present system and method helps the users who have no backyard to build an indoor pool in their family room or garage, saving money and space. Fifthly, the covering board stays horizontally in midair when the pool is open, acting as a sunshade to prevent harmful uv rays from harming swimmers, evaporating water, and falling into the pool.

Problems solved by technology

It can not only cover the pool but also lift the covering board and the loads on it.

The application of the electronic control technology invalidates partly the foregoing rules.

For example, if the lifting devices can't be vertical to the covering board, or / and their included angles can't be the same because of the restriction of the conditions, the system can't run according the above rules.

The electronic control technology enables the present system to apply to more complex installing conditions, but it would greatly increase the cost of the system.
