Abstract:
A combination cap and shoe set is provided wherein each of the cap and shoe include illuminated regions. For example, the brim of the hat may be illuminated in its entirety in a particular color and the sole of the shoe may be illuminated in a complementary color such that a person wearing the cap and shoe of the invention in low light situations may be readily visible. The sole of the shoe may also be substantially uniformly illuminated and the illumination may be controlled independent of any walking motion by the wearer by a manual push-button switch.

Description:
This application is a continuation-in-part of application Ser. No. 09/963,787 filed on Sep. 27, 2001, now abandoned which claims the benefit of Provisional Patent Application No. 60/235,572 filed Sep. 27, 2000 , and which is herein incorporated by reference. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to headgear and footwear containing illuminating elements. More particularly, the present invention relates to caps and/or hats having brims that are fully illuminated and shoes including soles that are switchably illuminated. 
     BACKGROUND OF THE INVENTION 
     Night safety for outdoor exercisers, e.g., joggers, pedestrians and cyclists, is an ongoing concern. Most people exercise outdoors either early in the morning before going to work or in the evening or at night after returning from work. In crowded urban environments, outdoor exercisers must frequently share the roads with motorists. Dawn and dusk are periods in which motorist&#39;s visibility is notoriously poor. Accordingly, exercisers must take extra precautions to ensure that they are visible to motorists. 
     In recent years, many exercisers have begun wearing bright or fluorescent colored clothing and/or passive reflectors. However, because these are purely reflective elements, it is necessary for them to be illuminated by an external light source, such as the beam of a motorists headlight, in order for them to function. 
     There are a several patents directed to caps having light sources attached to their brims. Some patents include caps having external, directed light sources attached to their brims. See for example, U.S. Pat. Nos. 4,406,040 and 5,741,060. The purpose of having light sources on these hats is to enhance the user&#39;s visibility so that the user can perform a desired task. However, these hats are not well suited for exercise activities such as jogging, walking or cycling because of the bulky nature of the light source attachment mechanisms. In addition, although they do emit light, they are not designed to make the wearer more visible in low light conditions. 
     There are still other illuminated caps that employ decorative lighting. For example, U.S. Pat. No. D318,338 includes a light source disposed at the center of the crown of the cap. U.S. Pat. No. 5,510,961 discloses a cap having several LEDs disposed along the perimeter of the brim. Neither of these patents is well suited to making the wearer more visible during low light situations or to providing large areas of illumination. 
     In recent years, athletic shoe manufacturers have developed a variety of shoes having illuminated regions. Some athletic shoes include illuminated portions on the shoe upper. Other athletic shoes contain illuminated portions in the heel. While still other athletic shoes contain illuminated regions in the instep portion of the sole. Typically, the light sources for these shoes are activated each time the wearer&#39;s foot makes contact with a surface and they remain active for a very limited duration (strobe, blink or flash). Thus, the wearer has extremely limited control over the duration of illumination. 
     SUMMARY OF THE INVENTION 
     In accordance with a preferred aspect of the invention, a cap having an illuminated region is provided that includes a crown and that may optionally include a brim extending from the crown. In one embodiment, the illuminated region may comprise the entire brim. In other embodiments, the illuminated regions may comprise letters formed in the brim arranged to spell a word or phrase. The illuminated regions may be tinted to radiate light of a particular color, if desired. 
     In accordance with another embodiment of the invention, shoes having illuminated regions may be provided separate from or in combination with the illuminated cap. The illuminated regions on the athletic shoes preferably include the sole. In some embodiments, the illuminated shoe may be provided with illuminated regions that extend along a substantial portion of the perimeter of the shoe sole. In other embodiments, the illuminated regions may comprise alphanumeric characters formed in the sole and arranged to spell a word or phrase.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     The present invention is directed to illuminated caps and shoes individually and in combination. A cap is provided with a plurality of illumination points to make the wearer more visible in low light situations. One or more of the brim of the cap, the seams of the crown of the cap and the button at the junction of the seams of the cap may be illuminated in accordance with the invention. Likewise, an athletic shoe may be provided with a plurality of illuminated regions including the tongue of the shoe, the entire sole of the shoe or portions thereof, the supporting material for the shoelace eyelets, decorative stripes disposed on the side of the shoe as well as other regions. 
     With respect to the cap, the illuminated brim is preferably the same size and shape as a regular brim that one would see in an ordinary baseball cap. There could be many different colored brims and hat matches, for instance the hat itself could be white while the brim is blue or any other color, or the hat could be red with a red illuminated brim. There are almost countless combinations. The brim is preferably comprised of a plastic or PLEXIGLAS® type of material molded into the shape of a regular brim that one would see today on a regular baseball cap. Likewise, the other illuminated regions may be of the same or different colors from each other. The owner of the cap has the choice of having his hat illuminated or off because of a switch that is preferably concealed underneath the material of the head fitting part of the hat. The owner of the hat can operate this switch through the material or fabric. The illuminated regions of the shoe may be color coordinated with the hat, if desired to present a well-coordinated apparel accessory set. 
       FIG. 1  depicts a cap according to the invention. As illustrated, a cap  10  includes a brim  12  and a crown  14 . Cap  10  may be in the style of a baseball cap, a fishing cap, or any other hat/cap that employs a brim. Brim  12  is preferably formed from polymeric material that permits substantial transmission of light, e.g. PLEXIGLAS®. Crown  14  may be formed from a breathable fabric such as cotton or canvas and brim  12  may be attached to crown  14  by any well known method. 
     In accordance with an aspect of the invention, as depicted in  FIG. 2 , a light source  16  is provided to illuminate brim  12 . Light source  16  may include light emitting elements  18  and a power source  20  and switch  22 . Alternatively, a single light source may be provided as illustrated in  FIG. 1   a . Light emitting elements  18 , e.g., LEDs, are preferably embedded within brim  12  to facilitate maximum light generation. Upon illumination of light emitting elements  18 , brim  12  may act as a lens and to magnify the intensity of light emitting elements  18  thus illuminating the entire surface area of brim  12  and creating significant radiation. If further enhancement of illumination is desired, small reflective particles may be embedded into brim  12 . 
     It is particularly preferred that brim  12  be substantially uniformly illuminated over its entire surface area. To that end, the polymeric material of brim  12  preferably diffuses light emanated from light source  18  so that there is a minimal light intensity differential from light source  18  across the surface area of brim  12 . Exemplary diffusing technology is disclosed in U.S. Pat. No. 5,879,076 that is herein incorporated by reference. 
     Alternatively, brim  12  may comprise a substantially opaque material having a plurality of translucent regions variously shaped and arranged. In keeping with a preferred aspect of the invention, the translucent regions may be formed in the shape of alphanumeric characters and arranged to display a message, i.e., a word, phrase or grouping of numbers. This illuminated message feature is particularly advantageous for manufacturers of athletic apparel as it can function as conspicuous advertising. 
     Power source  20  may be a small battery with sufficient strength to power light emitting elements  18 . Power source  20  is preferably disposed on an inner surface of crown  14  such that it is concealed from plain view. 
     To facilitate manual activation of lighting elements  18 , switch  22  is preferably a small push button switch of type commonly known in the art. Switch  22  may be disposed within an interior crown sweatband or liner and thereby hidden from view. The wearer can illuminate brim  12  by simply applying pressure to the outer surface of crown  14  at the hidden switch  22 . 
     In order to present a sleek, fashionable look, power source  20  and switch  22  are preferably concealed on an inner rim of crown  14 . In addition, it may be desirable for the brim  12  to radiate colored light. To that end, lighting elements  18  may be colored and/or brim  12  may be tinted. 
     In accordance with another embodiment of the invention, the illuminated cap  10  described above may be combined with illuminated athletic shoes  30  illustrated in  FIG. 3. A  suitable athletic shoe  30  is described U.S. Pat. No. 5,285,586 which is incorporated herein by reference. This combination may be worn as a fashion item or it may be used by performers such as dancers, actors marching band members and athletes in low light conditions to achieve special visual effects. For example, a marching band equipped with the combination illuminated hat and illuminated athletic shoes in accordance with the invention may present an impressive spectacle, as the individually illuminated heads and feet of its members move in synchronicity and create a symphony of light. 
       FIG. 3  illustrates a shoe in accordance with still another embodiment of the invention. The shoe includes a sole  105  attached to upper  110 . Sole  105  includes a translucent perimeter surface  115  having a light source  120  disposed therein. In keeping with the invention, light source  120  is preferably connected to a push-button switch  125  disposed on rear quarter  130 , as shown in FIG.  4 . Push-button switch  125  may optionally be concealed within the material of quarter  130 . 
     To capture the desired visual effects of the invention, it is important that sole  105  be substantially uniformly illuminated across the entire perimeter surface  115 . To that end, light source  120  may comprise a plurality of light emitting devices  135  contiguously positioned so as to appear to form a substantially uniform illumination pattern across perimeter surface  115 . 
     In accordance with another aspect of the invention, unlike many of the prior art illuminated shoes, the illuminated shoe of the present invention employs push-button switch  125  that facilitates continuous illumination when activated. Continuous illumination provides greater user control of the duration and timing of illumination and provides increased visibility over prior art shoes that employ blinking, strobing, flashing or intermittent light sources that are activated only when the wearer&#39;s foot makes contact with a surface. 
     In connection with still another embodiment of the invention, as illustrated in  FIG. 5 , sole  115  may be generally opaque and include translucent regions  140  variously shaped and arranged. For example, in some applications, translucent regions  140  may be in the shape of letters arranged to display a message, i.e., a word, phrase or a numeric phrase. Exemplary messages include the shoe manufactures&#39; name or the wearer&#39;s name or number. In the case of an athletic team, translucent regions  140  may be arranged to spell the team name or school name. For example, in some applications, translucent regions  140  may be in the shape of letters arranged to display a message, i.e., a word, phrase or a numeric phrase. Exemplary messages include the shoe manufactures&#39; name or the wearer&#39;s name or number. In the case of an athletic team, translucent regions  140  may be arranged to spell the team name or school name. 
     The translucent regions may be illuminated according to a number of different patterns. In keeping with one aspect of the invention, the translucent regions may be illuminated substantially uniformly or different regions may be illuminated to different intensity levels. In accordance with another aspect of the invention, the translucent regions may be illuminated synchronously, sequentially or according to any desired pattern. 
     The inventive combination is also particularly useful for joggers, pedestrians and cyclists as illuminating the head and feet thereby significantly increasing visibility. 
     Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternative embodiments, will be apparent to persons skilled in the art. It is, therefore, contemplated that the appended claims will cover all modifications that fall within the true scope of the invention.
