1. Field of the Invention
The present invention relates to devices for improving the traction of sport shoes used on court surfaces and, more particularly, to an anti-slip shoe accessory for court sports such as basketball, volleyball, racquetball and the like which is worn on the shoes.
2. Description of the Background
It is well known that athletes require good footing and traction between their footwear and the playing surface to avoid injury and perform at the highest level. Athletic shoes are designed to provide high traction between the sole of the shoe and the playing surface. Where the sole becomes dirty during play its ability to provide traction to the player may be compromised.
For example, when playing basketball on a dusty court, a player might realize partway through a game that the dust is affecting traction. Even on clean surfaces, bad traction can lead to injury.
Traction may be restored by cleaning the sole of the shoe. Fortunately, this is a simple affair. There are commercially available mats for shoes called Stick'Ums™. These may be placed on the basketball court sideline and players can step on it before or during the game. These mats have a top layer of adhesive-coated film that effectively removes dirt from shoes. The players simply step on the mat to remove dust. Alternatively, there are a variety of alcohol-based traction solutions available from sporting goods stores. These can be used to wet a towel which is placed on the sidelines so that players can wipe the bottom of their shoes. Though both the foregoing can be accomplished in just moments, they require the player to return to court-side, and so players must wait until short breaks in play. This is no help during play. Consequently, even professional basketball players are often seen licking their fingers while on the court and wiping the bottom of each shoe with their fingers. For obvious reasons physicians advise against this.
What is needed is a cleaning pad that can be secured to the shoe to provide a readily accessible cleaning element without the need to visit the sideline.
There have been a few past efforts toward this end.
For example, U.S. Pat. No. 4,823,426 to Bragga issued Apr. 25, 1989 discloses a Velcro™-attached shoe pad for dislodging, and picking up and retaining foreign particles and other matter adhered on athletic footwear soles. The cloth pad relies on mechanical brushing to clean.
U.S. Pat. No. 5,421,106 to Emrick issued Jun. 6, 1995 discloses a removable shoestring cover for athletic shoes which provides an upwardly facing wiping surface of suede or other material, and which cover is attached to the shoestrings at the upper and lower edge of the cover by flaps which fold around portions of the shoestrings and are held by a hook and loop type fastener.
U.S. Pat. No. 5,471,768 to Pryor issued Dec. 5, 1995 discloses a sneaker with built in atomizer for improved traction.
U.S. Pat. No. 5,555,564 to Welch discloses a shoe sole wiping pad sewn to the outer surface of an athletic sock. The wiping pad has a moisture-bearing wiping surface that removes dust and debris from the sole of an athletic shoe. The wiping pad cannot be removed from the sock for moisture replenishment.
U.S. Pat. No. 6,128,801 to Adzick et al. issued Oct. 10, 2000 discloses a shoe sole cleaner that removes debris from a sole of a user's shoe by swiping the sole over the shoe sole cleaner on the user's opposing shoe. A two-part mechanical fastener (e.g., hook-and-loop) secures the shoe sole cleaner to a shoe by its shoe laces. Again, the cloth pad relies on mechanical brushing to clean.
U.S. patent application Ser. No. 12/106,410 by Naughton filed Apr. 21, 2008 discloses a wearable wipe unit essentially comprising a Velcro™ attached towel.
Although the foregoing references are attached to the shoe or sock and can be used during game play, they primarily rely on mechanical brushing and are not very effective. A cleaning fluid is the most effective traction enhancer. However, simply impregnating a cleaning pad and attaching to a sneaker results in a relatively heavy device when worn, and impedes quickness. Moreover, any wetted or impregnated pad will tend to leave a residue on the soles, temporarily reducing traction. Even worse, the fluids can leach, spray or splatter during the game, resulting in wet shoes and socks. Even worse, the devices can leave moisture on the court and create substantial safety issues. What is needed is a light-weight low-profile cleaning pad assembly that can be removably secured to the shoe, designed to entrap a semisolid gel cleaner which avoids leaching, spraying or splattering of the gel.
It is, therefore, an object of the invention to provide a gel-impregnated cleaning pad for court shoes that is worn on the shoes and is extremely light weight (4 ounces or less) so as not to impede performance.
It is another object to provide a court-shoe cleaning pad as above that can be easily secured to the shoe to provide a readily accessible gel-cleaning element.
It is another object to provide a court-shoe cleaning pad as above that provides a readily accessible gel-cleaning and sequential drying element, e.g., a specially-designed gel-retaining pad within an encapsulating sneaker-attached cartridge that surrounds the pad with an integral wiping lip.
It is another object to provide a combination semi-solid (gellified) cleaner in combination with a specially-designed gel-absorbing cleaning pad to avoid leaching, spraying or splattering of the gel.
It is another object to provide a gel-absorbent court-shoe cleaning pad that is firmly secured to the shoe during play, yet easily removable for gel-replenishment or laundering.
In accordance with the foregoing objects, the present invention provides a combination kit including a particular gellified shoe cleaning fluid, a gel-retentive absorbent sole cleaning assembly, and an anchoring platform that can be secured to a shoe for removably attaching the sole cleaning assembly thereto. The sole cleaning assembly can be impregnated with the cleaning gel to provide a readily accessible court-shoe sole cleaning solution during game play and without the need to visit the sideline. The combination of materials used for the shoe cleaning gel, and for the gel-absorbent sole cleaning assembly avoids evaporation of the gel during play, and also avoids leaching, spraying or splattering of fluid during the game. The sole cleaning assembly includes a cleaning pad comprising a non-woven microfiber layer attached to a moisture-impermeable base layer, the two layers being held captive inside a surrounding plastic frame. In an embodiment, the plastic frame is substantially ovoid or elliptical and surrounds the cleaning pad, which is similarly-shaped. The cleaning pad may be sewn and/or adhered inside the plastic frame. The base layer is formed with a central elevation running centrally lengthwise along its major axis, which underlies the microfiber layer and elevates it slightly above the surrounding plastic frame. The surrounding plastic frame is formed with a raised wiper lip surrounding the cleaning pad so that as a shoe sole is brushed across the gel-wetted cleaning pad any residual gel is wiped clean by the raised wiper lip. A hook-and-loop attachment pad underlies the base layer, and a mating hook-and-loop attachment pad is mounted atop an anchoring platform which is laced to the user's sneaker. This allows the sole cleaning assembly to be removably attached along the forefoot of the sneaker via the platform so that it can be removed for easier gel-replenishment and/or cleaning.
In use, with the cleaning pad impregnated with gel cleaner and the entire sole cleaning assembly removably attached to the forefoot of the sneaker via the anchoring platform, the user simply brushes the sole of his opposing sneaker overtop/against the sole cleaning assembly. The entire length of the sole makes rubbing contact transversely across it, chemically cleaning the sole and the wiper lip of the frame immediately wiping excess or residue back into the absorbent pad. The process is repeated for the other foot. The device is remarkably effective at cleaning the soles of court-shoes and significantly improves traction. Moreover, the device is very lightweight (4 oz per foot), and can be used on-court anytime without the need to visit the sideline. The sequential fluid-cleaning and wiping/drying avoids leaving any residue on the shoes, and the combination of gellified cleaning fluid, gel-absorbing cleaning pad, and encapsulating frame avoids leaching, spraying or splattering of the gel fluid during play, all of which improves court safety.
Other objects, features, and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments and certain modifications thereof when taken together with the accompanying drawings in which:
Reference will now be made in detail to preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
The present invention is a combination kit, including a particular gellified shoe cleaning fluid, and gel-absorbent court-shoe cleaning and drying device that can be secured to the shoes to provide a readily accessible sole-cleaning and drying solution during game play, to improve traction without the need to visit the sidelines.
The dropper vial 3 is a commercially available flip-top plastic dropper vial. Vial 3 is preferably filled with a gel-viscosity glycerin/ethanol gel soap and tackifier solution consisting essentially of water, denatured alcohol, glycerin compound, gellifier(s), optional benzoic acid, plus fragrance and coloring agent(s) as a matter of design choice. The presently-preferred embodiment comprises 1 part glycerin, 1 part denatured alcohol, 3 parts water, gellifier, food coloring, and a bitter additive such as denatonium benzoate to deter anyone from drinking it. If desired, the benzoic acid may be added as an antimicrobial preservative. Glycerine also has an antibacterial potential, which alone or in combination with the benzoic acid has an added biocidal advantage. Basketballs and the courts that they touch, as well as the shoes that contact the court, are all well-known bacterial hotbeds. The preferred gellifier for the foregoing is polyacrylic acid added to reach a viscosity of between 5000-15000 cP, which is best suited for absorption into the fabric pad 20. Vegetable gums (agar, pectin, alginates, etc.) are possible alternative gellifiers. An alternative gel soap and tackifier solution may comprise polyethylene glycol (PEG) or methoxypolyethylene glycol (mPEG) cleaner, or other suitable PEG/mPEG detergents available from Dow Chemical under the trademark Carbowax™. Note that whether PEG, mPEG, glycerine cleaner, or some combination is used, these compounds are well-suited because they are completely non-toxic and non-acidic, and cannot not harm court floors.
In use, with the cleaning pad 20 impregnated with gel cleaner from vial 3 and the entire sole cleaning assembly 1 removably attached along the forefoot of the sneaker approximately over the second and third metatarsal bones, by tying the anchoring platform 4 to the laces as seen in
From bottom, the carrier platform 4 comprises a substantially flat plastic member formed in an elongate rectangular or oblong/ovoid surface 42 and having a plurality of pairs of stirrups 44 protruding downward from the surface 42 along both flanking sides. Each pair of stirrups 44 directly oppose each other and serve as pass-through anchors for lacing the carrier platform 4 to the forefoot of the sneaker. When laced tight as shown in
A first hook-and-loop pad 50 comprises a self-adhesive hook and loop pad formed in the same elongate rectangular or oblong/ovoid shape as surface 42 and adhered thereto with hook-and-loop attachment surface directed upwardly.
A second hook-and-loop pad 60 comprises the opposing self-adhesive hook and loop pad adhered beneath the cleaning/drying cartridge 2 so that it can be removably attached atop the carrier platform 4.
The cleaning/drying cartridge 2 comprises the absorbent fabric pad 20 sandwiched between the surrounding frame 10 and a moisture-proof backing 30. The absorbent fabric pad 20 comprises a non-woven viscose rayon/cellulose panel likewise cut/formed in the same elongate rectangular or oblong/ovoid shape. Specifically, a super absorbent shammy-type cloth of 80% viscose and 20% polyester is presently-preferred, cut from a 0.317-0.635 cm (⅛-¼″) thick cloth blank for proper gel-carrying capacity, into a 3-4″ long by 0.75-1.5″ wide oblong section. What is necessary is that the top-to-bottom dimension of the cleaning/drying pad 20 equal or exceed the breadth of the shoe sole, which is approximately 3.5″. In addition, the cloth preferably has a gsm weight of 260 within an acceptable range of from 200-300.
In the illustrated embodiment, the absorbent fabric pad 20 comprises an oblong section of non-woven viscose rayon/cellulose cloth 3″ long and 1.5″ wide. If desired, the absorbent fabric pad 20 may be silkscreened with team or corporate logos, or other branding indicia.
The absorbent fabric pad 20 is sewn and/or adhered to a like-shaped waterproof backing layer 30 which prevents leaching of the gel cleaner. In the preferred embodiment the waterproof backing layer 30 is preferably a thin section of plastic sheet pre-molded to retain a convex configuration, with a raised surface feature 24 defining a hump or other protrusion. This way, when used as a backing for the absorbent fabric pad 20 the raised surface feature 24 elevates the fabric pad 20 above the surrounding frame 10 thereby ensuring that when a sneaker sole is swiped across it makes firm contact with the raised surface of the fabric pad 20 and is fully exposed to the gel absorbed therein.
As best seen in the inset of
As indicated above, a hook-and-loop attachment pad 60 is adhered beneath the base layer 30, and a mating hook-and-loop attachment pad 50 is mounted atop the anchoring platform 40 which is laced to the user's sneaker. This allows the sole cleaning assembly to be removably attached along the forefoot of the sneaker via the platform so that it can be removed for easier gel-replenishment and/or cleaning.
In use, and referring back to
It should now be apparent that the above-described invention provides an effective anti-slip shoe accessory for cleaning the soles of court shoes such as basketball, volleyball, racquetball and other shoes, which is worn on the shoes for on-demand use even during play, without the need to visit the sideline. The gel cleaner and thick, absorbent viscose rayon/cellulose panel 20 encapsulated in a waterproof frame 10 avoids leaching, spraying or splattering of the gel even during active play, improving traction and court safety. Moreover, the biocidal nature of the gel improves sanitary conditions. Those skilled in the art will understand that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. It is to be understood, therefore, that the invention may be practiced otherwise than as specifically set forth in the appended claims.
Athletes participating in court sports such as basketball perform at their highest level when they have good footing and traction on the playing surface. For this reason many athletes keep a towel wetted with cleaning liquid handy on the sidelines to that they can run over and swipe their soles periodically. Of course, this is not possible during live game play, and such towels tend to leave excess fluids on the sole that can leach, spray or splatter during the game, resulting in wet shoes and socks. Even worse, the devices can leave moisture on the court and create substantial safety issues. There would be great industrial applicability in a light-weight low-profile cleaning pad assembly that can be removably secured to the shoe, designed to entrap a semisolid gel cleaner which avoids leaching, spraying or splattering of the gel.
