DETAILED DESCRIPTION

(21) While a small portion of the population suffers from excessively sweaty palms (1% of the population has palmar hyperhidrosis), most of the sweat that ends up on an athlete's hands actually originates from the athlete's armpits and arms. In fact, it has been found that approximately 80% of the water that reaches an athlete's palms actually originates from above the wrist.

(22) When an athlete is in a stationary position with their hands at their sides, sweat from the athlete's arms to stream down the pinky-side and middle of their palm, where it runs off of the pinky and ring fingers. However, when an athlete is swinging their arms or gripping a sporting implement (such as, for example, a tennis racket), the sweat from the athlete's armpits and arms tends to splash over their entire palm. While a small amount of moisture may actually improve an athlete's grip, excessive moisture may result in hydroplaning, which the athlete experiences as a slippery grip.

(23) Many athletes utilize hand towels and other such implements to remove sweat from their hands. While the use of such implements may remove excess moisture, the result is usually temporary, and the athlete's hands may quickly become slippery again. Moreover, the use of such implements is reactionary, rather than proactive. Hence, in typical use, an athlete experiences a compromised grip before turning to these implements, which may put the athlete at a competitive disadvantage.

(24) The various sweatbands developed in the prior art may provide a partial solution to this problem. However, conventional sweatbands are made from moisture absorbing materials, and are hence prone to fabric saturation. In particular, once the absorbing band becomes saturated, it resists the absorption of additional moisture. Consequently, any additional moisture will bypass the band. Moreover, if the saturated band is compressed, it will release moisture in the direction of gravity which, in the case of a performing athlete, will frequently be in the direction of the hands or face.

(25) Once saturated with moisture, perspiration absorbing bands may also act as thermally insulating devices on such areas of the body. Unfortunately, these devices are commonly worn on the wrist or forehead, which are points of the body that would otherwise act as heat dispersal locations. Consequently, the use of these devices may contribute to heat strain on the user's body. Perspiration absorbing bands also require frequent laundering, because they readily soak up moisture and dirt, and may develop an unpleasant odor.

(26) It has now been found that some or all of the foregoing issues may be addressed with the various devices and methodologies disclosed herein. In a preferred embodiment, these devices take the form of a non-porous, non-moisture absorbing band which is suitably contoured to deflect sweat away from the body. Thus, for example, in some embodiments, the band is implemented as a wristband which deflects (rather than absorbs) sweat before it passes the wrist. As a result, the amount of sweat reaching a user's palms may be significantly reduced. The use of such a band allows an athlete to proactively address the foregoing issues before they effect the athlete's performance.

(27) In a preferred embodiment, the device disclosed herein may be contoured to essentially act as a sweat receptacle which can hold and retain fluid. The trapped fluid remains in the device until dislodged by the motion of the user. For example, if the device is a wristband, the fluid may remain trapped in the device until the user moves their arm in a particular way. At that point, the motion of the user's arm effectively ejects the trapped fluid from the device, flinging it away from the user's body.

(28) Moreover, because the device is nonabsorbent, it does not suffer from the various issues arising from moisture saturation in prior art sweat bands. In particular, because the device is moisture deflecting (rather than moisture absorbing), the performance of the device does not decline during use (due, for example, to moisture absorption), and the device also does not require laundering (it may be readily cleaned by briefly rinsing it in water).

(29) In some embodiments, the devices disclosed herein may be used in conjunction with a glove. In such embodiments, the device prevents sweat from entering the glove, thus keeping the glove drier.

(30) In some embodiments, the devices disclosed herein may be suitably contoured to permit its use as a wipe or squeegee for the purpose of removing sweat from the user's body. For example, in some embodiments, the device may be implemented as a wristband with a suitably contoured surface that permits its use in wiping or squeegeeing sweat from the user's brow. This has the beneficial effect of keeping sweat out of the user's eyes.

(31) In some embodiments, the devices disclosed herein may be further usable (when it is not being worn) as a toy. In particular, because the device is generally annular in shape, it may be configured for use as a flying disc, saucer or other aerodynamic toy when it is not being worn.

(32) FIG. 1A illustrates a first particular, non-limiting embodiment of a device in accordance with the teachings herein. The device 101a depicted therein is a sweat deflector/channeling device comprising an elastomeric body 103a. The elastomeric body 103a is equipped with a central aperture 105a or slit through which a user's hand may be inserted to permit the device 101a to be mounted on the wrist of the user. In some embodiments, the central aperture 105a may be equipped with a fabric lining. The sweat deflector/channeling device 101a of FIG. 1A is further equipped with twin tails 107a or sweat dischargers, which allows perspiration to be channeled to, and ejected from, the tips thereof when the device is worn with the tails 107a facing away from the user's thumb. The device 101b of FIG. 1B is similar in design and function, but is equipped with a single tail 107b.

(33) FIGS. 2A and 2B illustrate a second particular, non-limiting embodiment of a device in accordance with the teachings herein. The device 201 depicted therein is a sweat deflector/channeling device comprising an elastomeric body 203. The elastomeric body 203 has first and second opposing major surfaces, and is equipped with a central aperture 205 through which a user's hand may be inserted to permit the device 201 to be mounted on the wrist of the user. In some embodiments, the central aperture 205 may be equipped with a fabric lining or flexible lip to fill any gaps between the device and the wrist of the user as may occur when the wrist is flexing (and thus, not perfectly round or oval). The sweat deflector/channeling device 201 of FIGS. 2A and 2B is further equipped with a protrusion 207 or tail which acts as a sweat discharger by allowing perspiration to be channeled to, and ejected from, the tips thereof when the device is worn with the tail 207 facing away from the user's thumb.

(34) The top view of FIG. 2A of the device 201 illustrates the protrusion 207 to which perspiration generally is channeled prior to discharge. As seen therein, the protrusion 207 is equipped with a first, longitudinally extending channel 224 which intersects with a second, annular channel 225 defined in a first major surface of the elastomeric body 203. The annular channel 225 in this embodiment is essentially V-shaped in a plane perpendicular to the channel, although in some variations of this embodiment, the channel may be C-shaped or U-shaped in cross-section.

(35) As best seen in FIG. 3, the elastomeric body 203 is equipped with a first peripheral lip 225 which is adjacent to the central aperture 205. The first peripheral lip 225 forms an inner seal where the elastomeric material of the elastomeric body 203 contacts the skin of the user. Preferably, the central aperture 205 is suitably sized such that the resulting seal is sufficiently tight to prevent most or all perspiration or liquid from passing the contact area.

(36) FIG. 4 illustrates a variation of the sweat deflector/channeling device 201 of FIGS. 2-3. This embodiment is similar in most respects to the embodiment of FIG. 3. However, while the central aperture 205 in the embodiment of FIGS. 2-3 is circular, the central aperture 305 in the embodiment of FIG. 4 is elliptical. In some applications, this shape may better match the general cross-sectional shape of the user's wrist or angle, thus providing a more complete seal.

(37) FIGS. 5A and 5B illustrate the cross-sectional geometry of the device 201 of the device of FIGS. 2A and 2B. As seen therein, the annular channel 225 of the device 201 forms a reservoir which entraps sweat from the body of the user while the reservoir is in a vertical direction. FIG. 5A shows the reservoir empty, and FIG. 5B shows the reservoir partially filled. As the reservoir tilts (due to the motion of the body of the user), the accumulated sweat is directed out of the protrusion 207 via longitudinally extending channel 224.

(38) FIG. 6 illustrates a further embodiment of a sweat deflector/channeling device of the type disclosed herein. The device 401 depicted therein is similar in most respects to the device of FIGS. 2-3, but is further equipped with a plurality of support elements 431 or struts which extend across the annular channel 425. These support elements help the device 401 maintain its general shape, even if it is stretched across the body of a user. As seen in the similar device 501 depicted in FIG. 7, in some embodiments, the support elements 531 may only extend partially across the annular channel 425.

(39) FIG. 8 illustrates a further embodiment of a sweat deflector/channeling device 601 in accordance with the teachings herein. The device of FIG. 8 is similar in most respects to the device 201 of FIGS. 2-3, but lacks the protrusion 207 of that device.

(40) FIG. 9 illustrates a further embodiment of a sweat deflector/channeling device of the type disclosed herein. The device 701 depicted therein is equipped with a plurality of radially extending support elements 728. Unlike the embodiment of FIGS. 2-3, in this embodiment, the reservoir 725 for accumulating sweat is created between the skin of the user and the cupped portion 727 of the elastomeric body 705. Moreover, in the device of FIG. 9, the inner seal 726 does not form part of the reservoir, but is located below it.

(41) FIGS. 10A-C and 11 illustrate a further embodiment of a sweat deflector/channeling device of the type disclosed herein. The device 801 depicted therein is in the form of an elastomeric ring that deflects and redirects perspiration to the peripheral lip thereof. As with the previous embodiments, the central aperture 805 in this device 801 is preferably sized such that the elastomeric body 803 contacts the skin of the user with sufficient tightness to ensure that most or all perspiration or liquid cannot pass the contact area.

(42) FIG. 12 illustrates a side view of the device 201 of FIGS. 2A-B and 3 on the wrist of a user (FIG. 14 illustrates a similar deployment for the device 801 of FIG. 10, and FIG. 15 illustrates the deployment of the device 201 of FIGS. 2A-B and 3 on the ankle of a user). As seen therein, the device 201 is positioned such that it captures perspiration in the reservoir 225 before being discharged via the longitudinally extending axis 224 of the protrusion 207 (see FIG. 2A). In some applications, the device 201 may be positioned in the opposing orientation, as shown in FIG. 13.

(43) As seen in FIG. 15, in some embodiments, the device 201 of FIGS. 2-3 may be employed in conjunction with, or incorporated into, a glove 1001.

(44) As seen in FIG. 17, in some embodiments, the sweat deflector/channeling device 1101 may be equipped with suitable means to allow the diameter of the central aperture 1105 to be adjusted. In the particular embodiment depicted, a series of apertures 1141 and protrusions 1143 are used for this purpose, although various other adjusting means may be utilized to similar end. These include, without limitation, the use of releasable or repositionable fasteners such as, for example, hook-and-loop type fasteners.
