ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention.
The present invention relates to a method and apparatus for spraying water, and more particularly to a method and apparatus for spraying a fine mist of water in order to cool off and/or entertain people.
2. Description of Related Art.
For generations, children, and even an occasional adult, have fought summer heat by running through lawn sprinklers. Although that activity is enjoyable, the spray from the lawn sprinkler tends to be rather coarse. Accordingly, the participants usually get very wet, very quickly.
In another attempt to cool people, some hotels in warmer clients have installed nozzles in sunbathing areas so that sunbathers may be misted with a very fine, gentle spraying of mist as they sit in the sun. These systems are permanently plumbed to an exterior wall or other structure of the hotel, and are not intended to be portable or otherwise dismantled. In addition, the mist admitted from such nozzles is intended to be barely noticeable by the sunbathers. Specifically, the spray is very subtle. See pages 40-41 of Water The Power, Promise, and Turmoil of North America's Fresh Water, National Geographic Special Edition, © 1993.
Another device of interest is fog making equipment that has been developed and used in the movie industry. This equipment is intended to be laid on the ground to emit a mist in such a manner so as to create fog along the ground. See U.S. Pat. Nos. 3,788,542; 3,894,691; and 4,039,144.
OBJECTS AND SUMMARY
It is an object of the present invention to provide heat relief to large crowds of people for safety and entertainment using environmentally friendly equipment and methods.
It is another object of the present invention to allow for varying degrees of mist to meet different crowd preferences, so that it is not necessary to get soaked to bring the body temperature down.
It is yet another object of the present invention to provide a modular spray assembly for spraying pressurized water.
It is still another object of the present invention to provide a temporary structure and spray assembly for spraying pressurized water which has a variable size depending on the crowd requirements.
It is another object of the present invention to provide a spray assembly for spraying pressurized water which creates a windy environment which is entertaining for all ages.
It is another object of the present invention to provide a modular spray assembly which is easy to put together and install.
A spray apparatus comprises a vertical tube having an inlet at one end thereof for receiving pressurized water, and a plurality of nozzles attached thereto; and means for supporting said vertical tube; each of said nozzles having an equivalent orifice diameter in the range of 0.026 to 0.076 inches.
A misting apparatus comprises a structure having a roof; a distributor mounted within said structure to the roof of the structure, the distributor including an elongate body having an inlet at one end thereof, an internal passage connected to said inlet and extending through the elongate body, and a plurality of openings spaced along said body, wherein each of said openings are connected to said internal passage; a plurality of nozzles for spraying a high pressure mist, each of said nozzles having an equivalent orifice diameter in the range of 0.026 to 0.076 inches; each of said nozzles connected to a respective one of said plurality of openings tubing interconnecting said distributor to a source of pressurized water.
Still other objects, features and attendant advantages of the present invention will become apparent to those skilled in the art from a reading of the following detailed description of the embodiments constructed in accordance therewith, taken in conjunction with the accompanying drawings.
