DETAILED DESCRIPTION OF THE INVENTION

[0019] The present invention will now be described more fully in detail with reference to the accompanying drawings, in which the preferred embodiments of the invention are shown. This invention should not, however, be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be complete and will fully convey the scope of the invention to those skilled in the art.

[0020] FIGS. 1-7 illustrate a spraying device 100 according to the invention. The spraying device 100 includes a delivery conduit 10 having a plurality of perforations or openings 20, the delivery conduit 10 adapted to connect to a liquid supply, such as a garden hose. The plurality of openings 20 approximately arranged in a straight line on a bottom side of the conduit 10 and configured to disperse the liquid out of the device 100. The device 100 also includes one or more handles 40.

[0021] The arrangement and configuration of the perforations 20 along conduit 10, as well as the positioning of the one or more handles 40, creates a spraying device that disperses large volumes of fluid over a large surface area rapidly and ergonomically, which lessens operator fatigue and improves productivity. The specific volume of water dispersed and the specific area that the device 100 covers in a given period varies based on the specific construction of the device. However, in general the device 100 is able to cover an area between approximately 5 square inches and approximately 40 square inches with a flow rate 1 to 15 Gallons Per Minute (“GPM”) at a supply pressure of approximately 50 pounds per square inch (“PSI”).

[0022] The delivery conduit 10 is a cylindrical conduit having sufficient rigidity to prevent the device from bending as water flows through the conduit 10 and out through the perforations 20. The conduit is open on one end 12 where it connects to the water supply, for example, by using a conventional threaded fastener. The second end 14 is sealed in a watertight manner with a smooth round cap 15. The cap 15 prevents the device 100 from becoming caught in a plants' trellis support netting and/or branches that are located around and/or throughout the entire plant. The diameter of the conduit may vary, however, a diameter between approximately ½ inch and approximately ¾ inch is preferred.

[0023] The openings 20 are located at and near the second end 14. More specifically, the openings 20 start near the second 14 and are arranged in an approximate shape of a straight line along the bottom of the device 100 towards the first end 12, with the line of openings 20 coming to an end before they reach an operators position to avoid dispersing fluid on the operator or unintended application surfaces.

[0024] In one embodiment, illustrated in FIGS. 3 and 4, the conduit 10 is approximately three feet and six inches in length. There are 10 openings 20 that are each spaced approximately 1 inch apart. The 10 openings 20 are arranged in a line starting approximately one inch prior to the cap 15 and extending towards the first end 12 of the device, thereby creating a delivery length of about 9 inches. In a second embodiment, shown in FIGS. 1 and 2, the conduit 10 is approximately 6 feet in length and has approximately 24 openings 10 that are spaced approximately 2 inches apart.

[0025] In most instances, the perforations 20 are predrilled holes 22 in the conduit 10. The size of the perforations 20 may also vary, for example, 11/64 inch is preferred, however, 3/32 of any inch is suitable for some applications. Nozzles 24, 26, 28, may also be inserted into the perforations 20, for example, by using a threaded fastener connection method. As noted above, conventional misting nozzle outlets have an efficiency problem. To address that, interchangeable nozzle outlets 24, 26, 28 may be provided, with different outlets having either adjustable cone spray patterns or having various horizontal angle patterns, e.g. 90 degrees, 180 degrees, etc. In all cases the nozzles' 24, 26, 28 have a 180-degree vertical angle patterns. The device may also be equipped with a variety of these nozzles in order to deploy a combination of horizontal and angle patterns, e.g. having an X axis of 90 degrees, 180 degrees, and/or 360 degrees, and a Y axis ranging between 45 degrees and 90 degrees. This enables each user to create a delivery path with the utmost precision and consistency for the specific purpose/plant. The perforations 20 may also be plugged if fewer perforations 20 are desired, for example, to decrease the delivery path and/or increase flow rate.

[0026] The spraying device 100 also includes an on-off valve 30. For example, a conventional barb or threaded ball valve may be used, the valve having a first position that opens the valve and allows liquid to flow into the device and a second position that closes the valve and prevents liquid from flowing through the device. In this embodiment, once the water supply/hose is activated there is a constant flow of water into the device 100, with the on-off valve 30 controlling the delivery of water out through the openings 20.

[0027] One or more handles 40 may also be provided. Each of the embodiments shown in FIGS. 1 and 2 and, separately, in FIGS. 3 and 4 include two handles 42, 44, that are configured in different manners for different purposes. For example, the design shown in FIGS. 3 and 4 is primarily for irrigation/fertigation of plant root zones in micro scale commercial agriculture. Here, the user is able to use the ring handle 44 to support the weight of the device 100 while using the straight end handle 42 to control the direction and positioning of the device 100 over the root area. The device shown in FIGS. 1 and 2 illustrates a handle arrangement for the longer configuration. In this embodiment, the device is shown in a configuration adapted for small to large-scale indoor or outdoor commercial agriculture, illustrating its use with a foliar spray application. In both configurations, the ring handle 44 includes a conventional adjustment mechanism 46 to enable the user to modify the angle of the handle 44 relative to the conduit 10 for a more ergonomic fit.

[0028] The device 100 may be made from a variety of materials, for example, a plastic such as high-density polyethylene is sufficient. Other materials such as aluminum piping and/or galvanized steel also are sufficient.

[0029] It is understood that the embodiments described herein are merely illustrative of the present invention. Variations in the construction of the spraying device may be contemplated by one skilled in the art without limiting the intended scope of the invention herein disclosed and as defined by the following claims.
