     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The invention pertains to the field of pest control and protection. More particularly, the invention pertains to single-purpose tick-repelling forearm and leg covering apparel for the prevention of tick bites. 
         [0004]    2. Description of Related Art 
         [0005]    There is an epidemic of tick-borne diseases in the United States and throughout the world. Anyone of any age who engages in any outdoor activity in any non-urban setting is susceptible to tick bites. Ticks are small arachnids, of the subclass acari, in the order ixodida that bury their head into the skin of the host to suck blood. Many ticks carry diseases or disease-causing substances. There are three families of ticks, ixodidae (hard ticks), argasidae (soft ticks) and nuttalliellidae. There are more than 200 known tick species. Tick borne diseases include: African tick-bite fever, angiomatosis, Astrakhan fever, babesiosis, bacteremia, boutonneuse (Mediterranean spotted) fever, cat scratch disease, Colorado tick fever, Crimean-Congo hemorrhagic fever, encephalitis, endocarditis, human granulocytic anaplasmosis, human granulocytic ehrlichiosis, human monocyclic ehrlichiosis, Israeli spotted fever, Kyasaur forest disease, louping ill, Lyme disease, meningoencephalitis (Powassan enchephalitis), Omsk hemorrhagic fever, peliosis hepatis, Q fever, relapsing fever (typhinia), Rocky Mountain spotted fever, tick-induced allergies, tularemia (Pahvant Valley plague, rabbit fever, deer fly fever, Ohara&#39;s fever), and typhus (Queensland tick t., Murine t., north Asian tick t., Indian tick t.). 
         [0006]    In North America, the primary disease vectors are the deer tick ( ixodes scapularis ), Lone Star tick ( amblyomma americanum ), American dog ticks ( dermacentor variabilis ), Rocky Mountain wood ticks ( dermacentor andersoni ), black legged tick ( ixodes pacificus ). In Europe, the main vector is castor bean tick ( ixodes ricinus ). Throughout Asia and eastern Europe, the taiga tick ( ixodes persulcatus ) is probably the most important vector. 
         [0007]    Ticks quest for hosts from the ground. They don&#39;t fly or jump. A questing tick lies in wait on the ground, in grass or leaves, waving its specialized questing claws so that it can grab and attach to a passing potential host. A tick may quest for days, weeks or even months. A questing nymphal deer tick is the size of the head of a pin. Detection of an attached tick is often difficult. Public health officials consider reasonable precautions against tick bites during outdoor activities to be wearing long pants and shirts with long sleeves, placing pant bottoms inside socks or boots, and careful inspection of the body after each exposure. These precautions are minimally effective. Placing pant bottoms inside socks simply prevents ticks from crawling under pants and onto legs. Ticks instinctively crawl up, so the strategy merely reduces the area of tick bites to the trunk and above. Furthermore, young ticks, and many adult ticks (e.g.,  ixodes scapularis ) are extremely small, and the presence of a tick may be overlooked even with the most careful inspection. It is often difficult for parents to consistently and thoroughly inspect children. Furthermore, human vanity is a considerable factor; pants tucked into socks is simply not an appealing fashion style. 
         [0008]    The best strategy is to repel or kill ticks as soon as they climb from the ground onto or fall from tall grass or other vegetation onto the limbs of the host, and to maximally cover the leg and forearm with an ixodicidal substrate. This is the teaching of the current invention. 
         [0009]    Furthermore, taking precautions to prevent tick bites must become a habit. Occasional efforts no matter how effective will leave an individual exposed at all other times as ticks are ubiquitous. The best solution will be one that is not only effective when used but also one that promotes habitual use. Therefore, it is important aspect of the current invention that it has the necessary features of habitual use apparel: single purpose, flexible, easy-to-use, durable, attractive, inexpensive and easy-to-maintain. 
         [0010]    The current invention is single purpose—its only purpose is to repel ticks. Dual purpose solutions, such as permethrin-treated socks, pants, shirts, leggings or hiking gaiters, inhibit habitual use. Dual purpose solutions are (1) impractical as they require dressing forethought—a showstopper when children are to be protected, (2) expensive, (3) inflexible, (4) style limiting or simply unattractive (e.g., hiking gaiters) for everyday use and (5) maintenance difficulty. Dual purpose also tend to lack the ixodicidal completeness of the present invention; each in its own way is strategically lacking. 
         [0011]    A solution must also be flexible in two ways: (1) it must conform to the variety of human leg and forearm sizes; and, (2) allow for the wearer to wear it over bare legs or forearms as well as clothed legs or forearms. This is all the more true for parents concerned with protecting children going outdoors. This is the approach of the current invention. 
         [0012]    A solution must be easy-to-use. The present invention slips on easily over pant bottom and holds the pants lightly against the leg and above the cuff of the invention, which causes any attached questing ticks to come in contact with the ixodicidal surface of the invention. 
         [0013]    A solution must be durable. For broad, habitual use a must last for repeated use in a variety of outdoor environments. Durability is not simply a cost issue to the consumer, but a factor in habitual use because the user must know that the solution is broadly effective for a variety of activities and always conveniently available. 
         [0014]    A solution must be attractive. A key component of habitual use is attractiveness. Adults and children alike loathe to use on a regular basis an unattractive item or solution. The current invention has appealing attractiveness characteristics. It can be printed or knitted in a variety of patterns that appeal to a wide range of tastes. It can match or contrast current clothing. It can be worn at different heights. It is unobtrusive and generally void of any fashion ugliness. 
         [0015]    A solution must be inexpensive. Cost is always an issue for any solution. Value of a single purpose is that a user may require only a single pair to achieve daily protection. Dual purpose requires a wardrobe. Design must be easy to manufacture and treat. One size fits most is a factor. 
         [0016]    A solution must be easy-to-maintain. To date, the most effective ixodicides (e.g., permethrin) are poisons. Apparel containing ixodicides must be washed separately from other items. Since the present solution is generally worn over pants, it must be laundered less frequently than garments exposed to the skin. Furthermore, it is much easier for the user to launder the invention separately from other garments rather than having to keep track of dual-purpose articles such as socks, pants, leggings, etc. coated with ixodicidal poisons. 
         [0017]    Numerous innovations for leg coverings or ankle bands that are designed to stave off tick bites have been provided in the prior art. Even though these innovations may be suitable for the specific individual purposes to which they address, they differ from the present invention in that they do not teach a ixodicidally-treated textile which grips the wearer&#39;s forearm or leg and covers the whole surface area with such ixodicidally-treated textile in order to kill or repel ticks as soon as they attach to a human&#39;s extremity. 
         [0018]    For example, U.S. Pat. No. 6,353,939 to Arber, teaches a disposable one-time use legging made of paper with upper and lower elastic bands that hold the tick repelling covering in place on the wearer&#39;s leg, for preventing tick bites by causing ticks to climb across externally mounted adhesive strips which capture them. The prevention strategy is that ticks will (1) climb onto the host from the foot and (2) will be captured by adhesive strips, and (3) will be rendered harmless when the device is disposed. It is a one-time use item. It is intended to be worn with shoes or boots and with the wearer&#39;s legs covered. 
         [0019]    U.S. Pat. No. 6,141,802 to Drake, teaches a tick barrier system for a pair of pants. The pants have an integral inner gaiter that fits snugly around the wearer&#39;s ankle and are stitched to the inside of the pant leg. The prevention strategy is to prevent tick contact with the wearer&#39;s skin by creating a cavity where the tick is frustrated in its attempt to find skin. Presumably the tick never finds the path up the outside of the pant leg and either drops off or is removed after careful post-wear inspection. 
         [0020]    It is apparent that numerous innovations for leg coverings have been provided in the prior art that are adapted to be used. Furthermore, even though these innovations may be suitable for the specific individual purposes to which they address, however, they would not be suitable for the purposes of the present invention as heretofore described. 
       SUMMARY OF THE INVENTION 
       [0021]    The present invention provides tick-repelling coverings to be worn by the user around the legs or forearms. In one preferred aspect there is provided a substantially tubular, stretchable, wearable covering, with cuffs at both ends, made of knitted or woven ixodicidally-treated textile, that when worn, repels or kills ticks. 
         [0022]    Briefly stated, the invention provides, in various preferred forms, a tick repelling covering formed by sewing or preferably circular knitting. The tick repelling covering is a stretchable cover that preferably is constructed from woven, stretchable fabric, which is a treated textile containing an ixodicide, such as the pyrethroid permethrin. The tubular covering has proximal and distal cuffs of elastic yarns, which serve to both keep the covering in place and form a physical barrier to ticks at the respective distal ends. The covering is worn on the leg of wearer, where the distal cuff holds the covering in place around the ankle, and when the wearer is wearing pants, provides sufficient pressure to prevent the bottom of the pant leg from protruding from underneath the covering, and thus not only providing a mechanism for causing ticks to make contact with the ixodicidally-treated fabric, but also depriving ticks a physical route to wearer&#39;s body, and the proximal cuff holds the covering in place just below the knee. Alternatively, the covering is worn on the forearm of wearer, where the distal cuff holds the covering in place around the wrist, and when the wearer is wearing long sleeves, provides sufficient pressure to prevent the cuff of the sleeve of the wearer from protruding underneath the covering, and not only providing a mechanism for causing ticks to make contact with the ixodicidally-treated fabric, but also depriving ticks of a physical route to the wearer&#39;s body, and the proximal cuff holds the covering in place just below the elbow, or, alternatively just above the elbow. The covering is easily slipped on over the foot when worn on the leg and over the hand when worn on the forearm. The covering is a treated-textile containing an ixodicidal agent of long-lasting effectiveness, meaning that it lasts through 25 washings of the covering or one year, whichever comes first. 
         [0023]    In one embodiment, the invention provides a tick repelling covering wearable on a human leg or human forearm. It has a stretchable, tubular structure that carries throughout its entire structure an ixodicide. In this form of the invention the covering repels or kills ticks, thereby preventing the human from being subjected to a tick bite, which can ultimately cause a large number of human diseases. 
         [0024]    In another embodiment, the invention provides threads that have been used to knit the covering may carry the tick repellent in a ultramicrocellular (UMC) form. 
         [0025]    A wide variety of insect control ingredients (especially ixodicidal repellants) may be used. Preferred repellents include highly volatile synthetic pyrethroids, such as permethrin. Other ixodida control ingredients include volatile insecticides, volatile insect-repelling natural oils, volatile insect growth regulators, and mixtures thereof. The materials that the covering are made of are not critical, albeit it is preferred that they be stretchable and provide an effective substrate for the ixodicide. 
         [0026]    Accordingly, this invention provides a convenient and inexpensive way to deliver an ixodicide to the extremities of the wearer. As such, protection can be achieved without directly coating an active ixodicide on human skin and/or clothing. 
         [0027]    The foregoing and other advantages of the present invention will be apparent from the following description. In that description reference is made to the accompanying drawings which form a part thereof, and which there is shown by way of illustration, and not limitation, preferred embodiments of the invention.

The proximal cuff of tube  14  when the wearer is wearing long sleeves fits snugly against the wearer&#39;s sleeve  34 , maintains the elastic tube  10  properly in place on the wearer&#39;s arm  30  above the elbow  42 , and serves as an additional area of repellent surface of where ticks  36  are killed or repelled by the repellent surface of the invention. When in place on the wearer  18 , distal cuff  12 , tubular body  16  as well as proximal cuff  14  are stretched slightly so that invention  10  holds the sleeves of the wearer close to the forearm in order to direct the ticks to the outer surface of the tick-repellent invention  10 . The proximal cuff  14  is preferably 2″ wide and approximately 2″ long when not stretched. Both distal cuff  12  and proximal cuff  14  include elastic yarns  38  as are usual in the trade for sufficient stretch and gripping. Both distal cuff  12  and proximal cuff  14  are integrally knitted to the tubular body using methods well known in the art. The body of the tube  16  may be knitted from nylon, acrylic, or cotton yarn  40  or other yarns as are standard in the trade. The tick-repelling elastic tube  10  as a whole including the distal  12  and proximal  14  cuffs should be approximately 2″ wide at top and bottom, and approximately 8″ (4″ less than the desired overall length). All dimensions are finished with cuffs and tubular body in a non-stretched state. 
         [0040]    FIGURE FIVE, which is a diagrammatic perspective view of the present invention in use, the tick-repelling elastic tube  10  is shown generally for covering and protecting the forearm  28  of a wearer  18 , when the wearer&#39;s forearm  28  is bare, from ticks  36 . The tick-repelling elastic tube  10  comprises a distal cuff  12 , a tubular body  16 , and a proximal cuff  14 . The distal cuff  12  of the tick-repelling elastic tube  10 , when the wearer&#39;s forearm is bare, serves to hold invention comfortably and snugly in place around the wrist  32  of the wearer, preventing the ticks  36  from getting therebetween and causes ticks to climb onto the repellent surface of the distal cuff  12 , body of the tube  16  or proximal cuff  14  where they are killed or repelled. The distal cuff  12  is preferably 2″ wide and approximately 2″ long when not stretched. The proximal cuff  14  of tube when the wearer&#39;s forearm  28  is bare fits snugly against the skin  24  of the wearer&#39;s forearm  28 , maintains the elastic tube  10  properly in place on the wearer&#39;s forearm  28  below the elbow  42 , and serves as an additional area of repellent surface of where ticks  36  are killed or repelled by the repellent surface of the invention. When in place on the wearer  18 , distal cuff  12 , tubular body  16  as well as proximal cuff  14  are stretched slightly so that invention  10  fits snugly on the forearm  28  in order to direct the ticks  36  to the outer surface of the tick-repellent invention  10 .

When in place on the wearer  18 , distal cuff  12 , tubular body  16  as well as proximal cuff  14  are stretched slightly so that invention  10  fits comfortably and snugly on the wearer close to the forearm and distal portion of the arm in order to direct the ticks to the outer surface of the tick-repellent invention  10 . The proximal cuff  14  is preferably 2″ wide and approximately 2″ long when not stretched. Both distal cuff  12  and proximal cuff  14  include elastic yarns  38  as are usual in the trade for sufficient stretch and gripping.

The tick-repelling elastic tube  10  as a whole including the distal  12  and proximal  14  cuffs should be approximately 2″ wide at top and bottom, and approximately 8″ (4″ less than the desired overall length). All dimensions are finished with cuffs and tubular body in a non-stretched state. 
         [0042]    In the present embodiment, the tick-repelling elastic tube is preferably knitted from a yarn that has the ability to frictionally engage the wearer&#39;s limb while avoiding constriction of the limb or compromising circulation in any manner. One example of a yarn containing these properties would be a yarn containing, cotton, acrylic, wool, polyester, nylon, elastand (spandex), nylon Lycra and/or elastic hydrocarbon polymer (rubber). Knit density, cross stretch, and levels of elasticity are changed through out the elastic tube knitting process to provide optimum fit and “stay put” qualities for tick protection. By controlling the number of ends of yarns, the density of the stitch, the number of ends of elastic yarns, the tension or lack of tension of the yarn feeds, the plaiting of the yarns in concert with each other and the dimensional sizes of the various yarns, the present elastic tube expands as needed to be put on or taken off, while frictionally engaging with the wearer&#39;s limb to offer “stay put” qualities and optimum fit and protection. 
         [0043]    In the preferred embodiment the fibers contain “free” permethrin applied after knitting. Alternative pesticides include any ixodicide, including compositions of natural and/or synthetic pyrethroids. 
         [0044]    In an alternative embodiment, the elastic tube for repelling ticks could be treated after knitting or fabrication with permethrin or other tick repellent chemicals using micro-encapsulation technology rather than “free” permethrin or other repellent. 
         [0045]    In an alternative embodiment, the elastic tube for repelling ticks could be knitted from threads/yarns made of ultramicrocellular (UMC) material containing a repellent such as permethrin. 
         [0046]    It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of constructions differing from the types described above. All dimensions are designed to fit an average sized woman. To fit other sizes, dimensions should be scaled accordingly. 
         [0047]    While the invention has been illustrated and described as embodied in a stretchable tube for covering and protecting the limbs of a wearer from, and repelling, ticks, however, it is not limited to the details shown, since will be understood that various omissions, modifications, substitutions and changes in the forms and details of the tick repelling covering illustrated and its operation can be made by those skilled in the art without departing from the scope of the appended claims. 
         [0048]    Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various application without omitting features that, from the standpoint of prior art, fairly constitute characteristics of the generic or specific aspects of this invention.
