     STATEMENT OF GOVERNMENT INTEREST 
       [0002]    The invention described herein may be manufactured and used by or for the Government for governmental purposes without the payment of any royalty thereon. 
     
    
     TECHNICAL FIELD OF THE INVENTION 
       [0003]    This invention relates generally to the field of portable drying and sanitizing for is multiple personal articles, such as boots, gloves, and helmets, using an airflow stream that is either ambient temperature or heated, and/or ozone infused. 
       BACKGROUND OF THE INVENTION 
       [0004]    In order to dry personal equipment and to prevent the problems associated with storing dampened gear, personnel have taken such mundane steps as spreading their damp items out on the floor or hanging them on racks after each use, and then returning them to the container. In more aggressive efforts, they have taken the steps of removing their damp items from their containers, and then use standard or specialized equipment to dry them, and then returning them to the container. There have been numerous blowing and drying devices invented for the purpose of drying shoes, boots, mittens and gloves. For example, see U.S. Pat. No. 4,768,293 issued to Kaffka, U.S. Pat. No. 4,198,765 issued to Miyamae, U.S. Pat. No. 4,145,602 issued to Lee. U.S. Pat. No. 3,645,009 25 issued to Ketchum. U.S. Pat. No. 3,417,482 issued to Peet, U.S. Pat. No. 3,154,392 issued to Littman. U.S. Pat. No. 2,614,337 issued to Darbo, and U.S. Pat. No. 2,443,695 issued to Russell, all of which are discussed in U.S. Pat. No. 5,720,108 issued to Rice. There have also been several specialized bags, devices, or containers developed to dry and sanitize athletic equipment or clothing. Some are small and portable, some are large and stationary, some are hard sided and some are made of flexible material. Of these, some are intended to dry the items while others only sanitize them. Most of these known prior art systems for treating damp or wet items have some common characteristics, but none incorporate all of the characteristics one would desire. 
         [0005]    Tactical military activities as well as active athletic sports such as hockey, football, lacrosse, and the like, require specialized equipment and specific clothing for use in completing the mission or playing the game and for protecting the person. Such clothing and equipment items are usually not worn constantly but are transported in some sort of a portable container such as a sports bag or specially container. During vigorous use such clothing and equipment items tend to become damp or wet by either the player&#39;s perspiration, or, and also, by being exposed to wet weather or environmental conditions. After an event is completed, if such damp or wet gear is left in a closed container, the gear tends to be acted upon by bacteria and mold, and as a result, becomes foul smelling and rank, and subject to deterioration. Research has shown that such odors are a byproduct of bacteria and mold that grow readily in the moist, dark, generally stagnant, environment inside the closed container. Some of the resulting bacteria may also become a source for infections when they come into contact with an open cut or abrasion on the body of a user the next time the gear is worn. In addition, items left inside a closed container dry so slowly that they may still be wet or damp the next time they are removed from the closed container. 
       OBJECTS AND SUMMARY OF THE INVENTION 
       [0006]    It is therefore a primary object of the present invention to provide a highly portable, self-contained, multiple-item drying system that directs an anti-bacterial air flow stream through a series of separate flexible, expandable, conduits (hoses) to provide an efficient, inexpensive, uncomplicated drying, sanitizing, deodorizing, and heating apparatus.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0018]    Referring to  FIG. 1  and  FIG. 2  concurrently, the present invention includes an air blowing assembly  10  consisting of; a housing enclosing an internal fan or blower (see  FIG. 3, 150 ), a rechargeable battery  40 , a battery charging power supply (see  FIG. 3, 180 ), an ozone generator (see  FIG. 3, 160 ), the various switches needed for controlling the system  60 ,  70 ,  80 ,  90  and ports  20 ,  30  for the electrical power required by the system, and a separate attachment consisting of; a manifold  110  with attached hoses  120  and attached to the distal end of the hoses  120 , ultraviolet light emitting diodes (UV-LED) for anti-bacterial effect  135 , and spring activated clamping clips  130 . The housing may be constructed of metal or plastic or other appropriate material. 
         [0019]    Referring to  FIG. 3 , the housing includes an air intake opening  50  which may include a screening or filtering device intended to keep out debris such as vegetation, pollen, sand, and insects. Connected internally to the air intake opening is a plenum  90 ) that directs the flow of air across and through heat sinks  170  that are associated with the battery  40  and power supply/battery charging system  180 , through the anti-bacterial ozone generator  160 , through the fan  150  or blower, and out of the housing through a port  100 , which has normally attached to it a manifold (see  FIG. 1, 110 ) separating the airflow into five flexible conduit hoses (see  FIG. 1, 120 ). 
         [0020]    Still referring to  FIG. 3 , the invention may be operated with the anti-bacterial ozone generation unit  160  either on or off. The invention includes a rechargeable battery  40  capable of powering the blower  150 , the ozone generator  160 , and the UV-LED&#39;s (see  FIG. 1, 135 ). The invention further includes an (preferably industry standard International Electrical Code (IEC) 60320 C13 type) electrical cord (not shown) and receiving socket (see  FIG. 2, 20 ) enabling the unit to be operated from alternating electrical current as found in common U.S. household electrical outlets, as well as recharging the battery from the same electrical source, or a direct current source such as a solar panel or automotive 12 or 24 volt electrical system. In a preferred embodiment the system power supply  180  electrical input section will be of an automatically sensing and setting type able to detect the input voltage level and frequency and automatically providing the proper output voltage regardless of input type. 
         [0021]    Referring again to  FIG. 1 , Coupled to the housing air outlet port  100  is a five port manifold  110  which connects a plurality (five) of flexible hoses  120  that are intended to direct the flow of output air to item(s)  140  to be dried, warmed and disinfected. The distant end of each hose segment contains a clip  130  which allows it to be fastened to the article to be treated, to prevent the hoses from becoming dislodged, and to direct the end of the hose in a direction which targets the flow of air to a particular location, such as into the toe box of a boot, or inside the fingers of a glove. Each hose also contains a pair of electrical wires encased into and running longitudinally down its length to provide power to an UV-LED for generating anti-bacterial light  135  attached to or embedded into the hose at its distal end. The power to the UV-LEDs  135  can be selected either on or off via a switch  80  mounted upon the system housing  10 . The removable manifold  110  is of such a size and circular shape as to allow it to be slid over the end of commonly found, portable, hair dryers, commonly referred to as a blow dryer, enabling the use of the manifold and hose subsystem removed and apart from the subject system air blowing assembly housing  10 .
