To address the need for cooling in open areas, fine mists of water have been used and released into the air substantially with an area to be cooled. The fine mist evaporates and provides a cooling of the air (evaporative cooling), thereby providing some measure of relief for individuals within the subject area. The fine mist is created by passing a liquid through a carrying tube and exiting through a nozzle such as the Cloudburst product manufactured by Mist & Cool, 1842 Washington Way, Suite B, Venice, Calif. 90291-4704. These systems, however, are not substantially portable in that they are used to provide cooling for a party, wedding reception, etc. that involve many people. Consequently, the pumping mechanisms are large and require electrical connection to 110-volt AC line power and the cooling system cannot be readily moved.
Misting systems are prevalent in the prior art. For instance, U.S. Pat. No. 3,583,147 purports to disclose and claim an evaporative air-cooling apparatus particularly adapted for vehicle cabs, which include a tank for water to be evaporated by a cylindrical porous pad and then pumped to a self-operated circulating nozzle. Air to the vehicle cab is being drawn through the pad and into the cab along a conduit in a heat-exchanging relationship to the water supply.
U.S. Pat. No. 5,613,371 purports to disclose and claim a method and apparatus for misting vehicle occupants. A golf cart or other open-air vehicle is equipped with an apparatus for providing a fine spray of water into the air inside and surrounding the vehicle, resulting in evaporative cooling for the occupants. A pumping system forces water from a water reservoir on-board the vehicle through mister nozzles. The pumping system uses a water filter, pump, and accumulator to achieve a steady spray. In the preferred embodiment, a pressure switch in the golf cart seat turns on the spray when an occupant is sitting in the cart, and stops misting when the occupant is not seated. Alternatively, the misters may be switched to spray continuously or turned off.
U.S. Pat. No. 3,738,621 purports to disclose and claim a rooftop evaporative cooler for cooling the interior of vehicles, such as campers and trailers, whether the vehicle is moving or stationary. The unit includes a rear-facing streamlined housing disposed over a rooftop register. The forward surface of the housing slopes upwardly from the vehicle roof to a horizontal rear portion adjacent a rear-opening, louvered entrance port. A suction fan is disposed with the housing between the entrance port and the register for pulling air into the housing through an evaporative pad and for expelling cooled air, guided by the configuration of the housing, through the register into the vehicle. The cooling medium is pumped from a supply tank contained within the housing to a distributor over the pad and collected after it passes through the pad for recirculation. The supply tank is substantially toroidal and is disposed within the lower portion of the housing, surrounding the rooftop register. The pad is constructed of a suitable porous material and the cooling medium is typically water.
U.S. Pat. No. 4,360,368 purports to disclose and claim the sealed, compact air-conditioner employs the evaporation of water and permits the lowering of the ambient temperature in cabs of machines or vehicles with no compressor or refrigerating circuit being required. The invention comprises a turbo-fan unit directly mounted against an evaporation chamber. Inside the latter, a box facing the air inlets conditions the air distributed toward water injection nozzles and ensures the seal on the upstream side of the chamber. On the opposite side, the outlet for the humidified fresh air is disposed in the upper part and is preceded by a droplet-separating medium. The evaporation chamber, associated with the deflector, constitutes a water recovery pan and is continuously drained by a drain located in the lowermost point thereof. The air-conditioner may be employed for the air-conditioning of agricultural, public works, handling, or cross-country machines or vehicles, such as tractors, harvester-threshers, shovelors or loaders.
U.S. Pat. No. Des. 294,636 purports to disclose and claim an ornamental design for an evaporative cooler.
U.S. Pat. No. 5,285,654 purports to disclose and claim an evaporative cooling system for mounting on the roof of a vehicle in which the sole source of water supply for the evaporative media in the system is contained in a low-profile housing mounted above the roofline of the vehicle.
With respect to golf related activities, cooling devices have been devised, utilized and known to consist of familiar, expected and obvious structural configurations. Prior art however, appears totally devoid of any portable misting system, which would allow maneuverability of a misting system between a plurality of golf course/golf range locations. In so doing, the instant invention enhances the art by allowing golfers to hit or drive golf balls from a natural turf surface. This ability is a direct consequence of the mobility of the instant invention as it allows for continuing growth of grass, turf and other structures typically encountered within the golf course environment. This huge benefit of the instant invention is in stark contrast to those utilized on driving ranges commonly found today which relegate golfers to hit golf balls from artificial turf surfaces.
Consequently, there is a need in the art for a portable, easy to install, versatile, and inexpensive evaporative cooling system, with the system adaptable to a variety of AC or, potentially DC applications to cool individuals engaged in outdoor sporting activities.
In these respects, the adaptable and portable cooling apparatus according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus developed for purposes of cooling golfers practicing at golfing ranges as well as other individuals engaged in other outdoor sporting activities, while allowing continued growth of grass, turf and other surfaces.
In view of the foregoing disadvantages inherent in the known types of cooling devices now present in the prior art, the present invention provides a new cooling apparatus construction wherein the same can be utilized for cooling golfers at a driving range, baseball batting cages or other similarly situated environmental surroundings.
The present invention includes a portable, liquid based cooling system that operates on an alternating current (AC) or a direct current (DC) power source. The system also includes tubing and/or pipes to carry a pumped liquid to nozzles coupled to the tubing or pipes to release the liquid into the air in a fine mist. The liquid mist evaporates and cools the air, thereby providing an inexpensive and intentionally transportable cooling system.
According to one aspect of the present invention, the tubing that carries liquid from a liquid source, such as a municipal or private water line (connection) to a nozzle can be a rigid or flexible, insulative tubing that allows a user to configure the tubing to easily accommodate the cooling system to various applications. In addition, the nozzles may be adjustable to alter the mist droplet size exuded by the nozzle or its misting area, thereby allowing a user a substantial amount of flexibility to alter the cooling to one's personal taste. The nozzles are strategically located about predetermined positions in the front, rear, or side portions of the apparatus and release a fine liquid mist into the air. The liquid then evaporates as it travels in the air and causes the air to cool at a region about a golfer on the driving range or other similar structure.
According to another aspect of the present invention, an air-conditioned driving range is disclosed, wherein the range includes a portable, liquid based (such as water) cooling system. The cooling system may optionally include an insulative storage tank for the preferably cool liquid and a pump for pumping the liquid through one or more tubes having nozzles.
According to yet another aspect of the present invention, the cooling system includes a pump or other water supply means, which provides fluid to the one or more nozzles in a substantially non-pulsating manner.
According to another embodiment of the present invention, the pump operates in a substantially non-pulsating mode by use of a bypass valve associated with the pump. The bypass valve operates to pass fluid from the pump inlet to the pump outlet when the outlet pressure increases above a predetermined level, thus maintaining the outlet fluid pressure relatively constant.
To the accomplishment of the foregoing and related ends, the invention comprises the features hereinafter fully described and particularly pointed out in the claims. The following description and the annexed drawings set forth in detail certain illustrative embodiments of the invention.

In reference to
The frame structure 22, 25, 27 of the instant invention may be constructed from and comprised of metal, polyurethane, wood or other similarly intended materials necessary to define and support the structure as described herein. The frame structure (22, 25, and 27) further plays an integral role and constitutes an attachment conveyance by which male electrical plugs and wire 1, female electrical plugs and wire 2, quick disconnect wire inlets 3, quick disconnect water outlet 4, a 120 Volt AC fan 5, a cup-holder 6, section connector clips 7, misting nozzles 8a and supply pipes 8b, an electrical terminal box 9, fan mister on/off switches 10 which may be positioned thereon or placed near or within the enclosed driving station area, and attached wheels 11, which enable the ready transitioning of the portable misting system 20 between any number of physical locations.
The present invention relies upon connection to a readily available water supply and is facilitated by direct connection of the quick disconnect water inlet 4 described above. For purposes of full and enabling disclosure, the structural elements associated with the frame structure of the above-noted invention and location thereof are provided for purposes of example only. The present invention allows for versatile structural element placement and is not to be construed as limited to the positioning posture as defined herein.
As mentioned, the portable misting system 20 includes a plurality of nozzles 8a that are preferably adjustable or replaceable to allow a golfer or other individual to alter the direction in which a liquid mist is released and/or alter the liquid mist droplet size. Such capability provides substantial flexibility to an individual to account for wind, humidity one's personal subjective tastes, and to also vary the emission area (a narrow mist stream or a wide mist stream).
Although depicted in one position of the structure, the nozzles 8a may be positioned in the front, sides or rear of the enclosed driving station area. In such case, a tube or tubes 8b may be run above, under the bottom, or along the side of the enclosed driving station area without substantially interfering with operational or aesthetic aspects of the range. When the system 20 is operational, fluid (e.g., water or other suitable fluid) traverses the system's tubing 8b and enters into one or more nozzles 8a. The nozzles 8a convert the liquid into a fine mist, which provides an evaporative cooling effect. The nozzles 8a are preferably removable to allow for easy replacement or nozzle cleaning. A person of the ordinary skill of art will understand, the nozzles 8a may be secured or locked into place via any known attachment and/or locking mechanism.
An optional pump 12, if utilized, is preferably a 110 or 220-volt portable water pump 12 that is operable to pump the liquid from a container 13 to the nozzles 8a at a pressure of about 40 PSI or greater. More preferably, the pump 12 is sufficiently high-powered to pump the fluid at about 60 PSI. The pump 12 receives the fluid from the tube at an inlet port (not shown) containing a filtering means and pumps the fluid into an output tube at an outlet port. The system of the present invention also provides a means by which alternating current (AC) and/or direct current (DC) power is provided via electrical wires and connectors, which can be secured to the frame structure.
As shown in
In reference now to
a and 3b together illustrate an alternative embodiment of the instant invention.
