SANITIZING CABINET FOR SPORTS EQUIPMENT
FIELD OF THE INVENTION
The present invention relates to an apparatus and a method for treating sports gear to sanitize the same.
BACKGROUND OF THE INVENTION
The problem of odors, mold, and mildew associated with sports equipment is common. Thus, while clothing and apparel can be washed and dried in a normal manner, much equipment cannot be subject to these processes. For example, in the sport of hockey, skates and protective pads and other paraphernalia cannot be put in commercial washers and dryers. Similarly, shoes and pads from other sports such as soccer and basketball cannot be washed and dried in a conventional manner.
It is known in the art, as shown in U.S. Patent 5,369,893, that one may use self-contained dryers for accommodating sports equipment. The dryers have walls which cause heated air to recirculate in the drying chambers to decrease the moisture content of the air and increase the drying energy efficiency. Blowers and fans associated with electric heaters operate to circulate heated air through the drying chambers.
U.S. Patent 5,369,892 discloses a chest or foot locker structure with a rigid housing wherein the top of the housing has a cover movable to an open position to allow access to the drying chamber. A motor driven fan located in an air mixing chamber within the housing draws air through a filter into the drying chamber. Air porous walls within the drying chamber allow air to mix the drying chamber back to the air mixing chamber for recirculation back into the drying chamber. Air also flows out of the drying chamber through a filter having activated charcoal to remove odors from the air discharged into the -1...

environment. This dryer utilizes an internal motor and fan associated with the electric heater and specialized porous walls within a housing.
U.S. Patent 6,134,806 discloses a portable sports equipment bag having an air distributor which is connected with a hose to a blower and ozone generator operable to move air and ozone under pressure into the air distributor. The air distributor's one or more manifolds located within the bag, the manifolds having a plurality of apertures to allow air and ozone in the manifolds to flow into the bag to dry sports equipment and objects within the bag. There are air filters mounted on the bag to remove odors and foreign matters from the air flow from the bag into the environment.
U.S. Patent 6,263,591 discloses a portable sports equipment drying container comprising a body having a cover with an input fan mounted in one of the side walls and an output fan mounted in another one of the walls. The fans are used for drying the moisture wet clothes and equipment placed in the container for circulating air through the container.
It is also known from the teachings of U.S. Patent 6,889,449 to use ozone to sanitize sports equipment.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a method and apparatus which would sanitize sports equipment and which method and apparatus is suitable for use on a commercial basis and which has an improved efficacy.
Preferably, the cabinet is provided with means for securely sealing the same during the period of time when ozone containing air is within the cabinet. The tight sealing is required to prevent the escape of ozone and the possibility of environmental damage.

-2-The walls of the cabinet can be formed of a transparent or opaque material resistant to ozone deterioration. Within the cabinet are means for accepting sports equipment, and in one embodiment, foraminous shelves may be provided. Naturally, hooks and other types of retainers may be utilized for any specialized equipment.
A preferred means of circulating the ozone containing air through the cabinet preferably comprises a pair of reversible fans located within the bottom wall of the cabinet defining the space for receiving the sports equipment. Such fans are known in the art and need not be described and detailed herein.
In operation, the sports equipment to be sanitized is placed within the cabinet and the access opening closed. Subsequently, ozone containing air is circulated throughout the cabinet. This is continued for a period of time which, in the preferred embodiment, would range between 5 and 15 minutes and more preferably, approximately 10 minutes.
It has been found that the ozone treatment has a higher efficacy if an ultrasonic generator is utilized while the ozone is present in the chamber or cabinet.
Without being limited to any theory, it is believed that the use of an ultrasonic generator aids in the penetration of the ozone into the equipment. However, this invention is not limited by any particular theory of operation.
The ozone generator may conveniently be placed in the bottom of the cabinet and one or more ultrasonic transducers placed within the cabinet. Operation of the ultrasonic generator can be controlled as desired. Thus, it may be utilized either continuously or for defined periods of time. Suitable timers or the like may be utilized.
Subsequently, an agent is lightly sprayed in a mist and the cabinet is maintained closed for a period of time sufficient for the ozone level to go down to at least 3 ppm and

-3-preferably below 2 ppm. The cabinet can then be opened and the sports equipment removed.
Preferably an ozone depleting agent is sprayed into the cabinet. While there are many compounds and compositions which are known to function as an ozone depicter, a particularly preferred embodiment utilizes a tea tree oil also know as a melaleuca oil. The advantage of such an oil is that it acts as a disinfectant.
In a preferred embodiment of the invention, the ozone depletion agent may be placed on a container and there may be provided means to ensure that the agent is dispersed a certain time prior to opening of the doors. Such control means are well known in the art and may include suitable timers and interlocks, as well as means to ensure that the ozone depleting agent is present in the container.

Having thus generally described the invention, reference will be made to the accompanying drawings illustrating an embodiment thereof, in which:
Figure 1 is a perspective view of a sanitizing cabinet according to an embodiment of the present invention;
Figure 2 is a front elevational view thereof illustrating use of the sterilizing cabinet;
and Figure 3 is a front view of a sanitizing cabinet having ultrasonic capabilities.
DETAILED DESCRIPTION OF THE INVENTION
As shown in Figures 1 and 2, there is provided a sterilizing cabinet which is generally designated by reference numeral 10. Sterilizing cabinet 10 includes a base member 12 and four structural uprights 14 extending upwardly therefrom.

-4-, , , . .
, A compartment is defined by a compartment floor 16, a front panel 18, a rear panel 20, and a pair of side panels 22, 24. As will be seen in Figure 1, a pair of front panels 18 are hingedly connected. When closed, a locking handle 28 is designed to engage the other front panel 18 to maintain the compartment tightly sealed.
Placed within sanitizing cabinet 10 above floor 16 are a pair of foraminous shelves 30. Foraminous shelves 30 may be of various types of structures, either a mesh or using wires.
Mounted in floor 16 is a first fan assembly 32 which is adjacent side wall 22 and a second fan assembly 34 which is adjacent side panel 24.
Mounted in the lower portion of sanitizing cabinet 10 below floor 16 is an ozone generator 36.
A first conduit 38 is in fluid communication with first fan assembly 32 while a second conduit 40 is in fluid communication with second fan assembly 34. A
connecting conduit 42 is connected to ozone generator 36 and is designed to supply both first conduit 38 and second conduit 40.
A reservoir 44 is provided to contain a supply of an ozone depleting agent having one or more additives therein. The water is connected via conduits 46 to spray heads 48 mounted in the upper portion of the sanitizing cabinet 10. A control panel (not shown) may contain conventional control circuitry including timers and interlocks. In this respect, there is provided a scale 60 which is designed to continually monitor the weight of reservoir 44 to ensure that the ozone depleting agent is present in a quantity sufficient to be sprayed within the cabinet. Naturally, other methods such as sensors within the reservoir 44 may be utilized. In all instances, lack of the presence of the ozone depleting agent

-5-would not permit operation of the apparatus.
In operation, and as shown by arrows 50, first fan assembly 32 is driven in a first direction to circulate the ozone containing air from first conduit 38 to a second conduit 40.
Subsequently, the direction of circulation is reversed by reversing the directions of first and second fan assemblies 32 and 34 respectively. It will be noted that the ozone containing air circulates throughout the cabinet in order to assure that it contacts all the equipment placed therein.
The bottom may be removed as a unit by means of handle 62 to facilitate servicing.
Referring to Figure 3, there is illustrated a cabinet which may or may not be similar to the previously described cabinet. In this embodiment, cabinet 70 has mounted therein an ultrasonic generator generally designated by reference numeral 72. Connected to ultrasonic generator 72 are a pair of ultrasonic transducers 74 and 76 which are located within the cabinet. Such ultrasonic transducers are known in the art as is the ultrasonic generators. The ultrasonic generator may be utilized for at least a portion of the time when ozone is present in the cabinet.
It will be understood that the above described embodiment is for purposes of illustration only and that changes or modifications may be made thereto without departing from the spirit and scope of the invention.
