This application claims priority based on U.S. Provisional Application No. 61/618,924, filed Apr. 2, 2012. The contents of which is incorporated herein by reference in its entirety.
TECHNICAL FIELD OF THE INVENTIONThe present invention relates generally to supplemental removable stick on cleat for footwear and more specifically to removable stick on cleat that can be reasonably secured to the sole of footwear for athletic use to convert the shoes to spikeless street shoes.
STATEMENT OF FEDERALLY FUNDED RESEARCHNone.
INCORPORATION-BY-REFERENCE OF MATERIALS FILED ON COMPACT DISCNone.
BACKGROUND OF THE INVENTIONWithout limiting the scope of the invention, its background is described in connection with golf shoes, and more particularly to converting spikeless street shoes into spiked golf shoes with a removable spike plate.
There are many types of athletic shoes which have spikes or cleats on the sole thereof to give fraction to the user of the shoes. One of the most common types of spiked athletic shoe is the golf shoe. One of the drawbacks to spiked athletic shoes is the amount of time required to remove the shoes and put on conventional street shoes in order to walk through most public places. In addition to the time required to change the shoes, it is necessary to carry a second pair of shoes in some fashion, and then to carry the golf shoes once they have been removed.
Another drawback to spiked athletic shoes is the rigid flat sole of the spiked athletic shoes. These rigid soles provide a surface for the spikes to be mounted and a foundation for the construction of the shoe. Although the inner surface does generally have padding, the rigid flat sole may irritate or injure the foot of the wearer, especially over prolonged periods of time, e.g., calluses, blisters, promote premature foot fatigue and flatten the wearer's foot due to the lack of arch support.
In addition, many junior golfers want to wear their designer sneakers while playing golf or cannot afford traditional golf shoes. Also individuals who enjoy golfing while traveling or on vacation can rent golf clubs at the golf course, but cannot rent golf cleats. Individuals must either purchase a new pair of golf cleats, which can be extremely expensive, or else go through the hassle and struggle of packing their golf cleats for travel. This is acerbated when traveling by plane since the airlines frequently charge extra fees for carry-on space, which may prevent many individuals from bringing bulky equipment such as golf cleats. Buying a new pair of golf cleats while on vacation is not cost-effective, and may be uncomfortable to wear during breaking in. Although there are some removable golf spikes available, these do not address all of the drawbacks in a single unit.
For example, U.S. Pat. No. 6,948,261, entitled, “Supplemental Removable Stick on cleat for Footwear,” discloses a removable stick on cleat covering for the treaded bottom of an athletic foot covering provided in one embodiment of the present invention. In this embodiment the stick on cleat includes an elastically deformable band defining a continuous loop, the band having a top edge and a bottom edge, the bottom edge of the band forming the shape of the border of the treaded bottom of the athletic foot covering, a sole surface coupled to the bottom edge of the band, the sole surface configured in the shape of the treaded bottom of the athletic foot covering and a plurality of sport cleats protruding from the bottom side of the sole surface.
U.S. Pat. No. 6,032,386, entitled, “Golf Shoe with Removable Sole,” discloses a sport shoe, particularly suitable for golf, provides a shoe with a base section sole and an overlying sole that is selectively removable from the base section sole. The base section sole can be spikeless, or include one type of spikes, while one or more overlying soles can include different spike types or spikeless faces. In one example, the base section sole contains metal long spikes that seat within magnetic recesses of the overlying sole. The overlying sole includes short plastic spikes or a spikeless face.
U.S. Pat. No. 5,661,915, entitled, “Shoe with Removable Spike Plate,” discloses a shoe that includes a spike plate with spikes thereon, removably attached to a sole portion of the shoe to permit selective removal of the spike plate. The shoe includes a rib extending around the peripheral side wall of the sole, and the spike plate includes an upright wall extending around a peripheral edge of a base plate, the spike plate wall having a groove formed on an interior surface thereof cooperable with the rib to selectively connect the spike plate to the shoe. The spike plate includes a forward section pivotally connected to a rearward section along a transverse axis to permit the forward section to pivot downwardly generally orthogonal to the rearward section of the spike plate.
U.S. Pat. No. 5,600,901, entitled, “Spike Convertible Sport Shoes,” discloses an attachment for converting a non-spiked dress or sport shoe to a spiked shoe for golfing or other walking or running activities and includes two clam-shell like attachment halves which are pivotable and to mountable against the sides and bottom of an underlying shoe. The attachment has a longitudinally-extending slitted upper and vertically-extending slitted heel both of which mount suitable fastener elements such as hoops and loops elements or snap-on buttons or a lacing and eyelet fastener or a zipper fastener. After the attachment is pivotally opened up in the manner of a clam shell, the attachment is placed about the bottom and sides of the non-spiked dress or sports shoe on the user's foot and the fastener(s) cinched up to securely hold the attachment on the underlying shoe so that there is essentially no relative movement there between, when the user is walking or engaging in his or her golf swings.
U.S. Pat. No. 3,643,352, entitled, “Overshoe for Golf,” discloses an overshoe for use in playing golf and other sports. The overshoe is of the flexible resilient kind which is stretched over an ordinary shoe and it has a plurality of cleats to give good footing. The cleats are located within holes in the outer sole of the shoe and have threaded stems which are engaged within threaded openings in washers located on the inside of the overshoe. The washers are overlain by separate heel and sole pads which are in turn overlain by a complete insole.
U.S. Pat. No. 8,356,426, entitled, “Article of Footwear,” discloses a kit comprising at least one shoe and at least one detachable sole section. An article of footwear comprising a shoe and at least one means for connecting the shoe to at least one detachable sole section. An apparatus comprising at least one detachable sole section.
SUMMARY OF THE INVENTIONStick on Cleats of the present invention can transform any pair of shoes or sneakers into a functional pair of golf cleats. The present invention is perfect for golfers who travel or who are on vacation and cannot bring their golf shoes with them due to limited packing space and extra luggage fees enforced by many airlines. The present invention ensures that an individual not miss out on a golfing opportunity simply because they have not been able to bring their golf shoes while traveling, and instead allows them to golf effectively wearing their favorite, most comfortable pair of shoes. Individuals will not have to purchase a new pair of golf cleats in order to golf, which can be extremely expensive, especially for only a round or two of golf. The present invention can attach securely to the bottom of any regular shoe or sneaker, and provides the grip and traction of a quality golf cleat. Instead of traveling with the extra bulk of golf cleats, individuals can save money and valuable space by picking up a pair of these disposable stick on cleats of the present invention for their vacation or travel golf outings.

Base plate 2 is preferably formed of a plastic material which has resilient flexible characteristics, so as to conform to the sole portion (not shown) of the shoe (not shown). Obviously other materials such as metal or rubber, polymers, plastics or the like may be used as well. The base plate 2 having a plurality of spikes 6 depending from the bottom surface thereof is provided for removable attachment to a sole portion (not shown) of a shoe (not shown). A shoe (not shown) may then be utilized as a spiked golf shoe or the like, yet permits use as a conventional street shoe, by reversing the process to remove the base plate 2 from the sole portion (not shown) of shoe (not shown).
Obviously other materials such as metal or rubber, polymers, plastics or the like may be used as well. An adhesive layer 8 is positioned on the back of the base plate 2 to adhere the base plate 2 to the sole portion (not shown) of the shoe (not shown). A shoe (not shown) may then be utilized as a spiked golf shoe or the like, yet permits use as a conventional street shoe, by reversing the process to remove the base plate 2 from the sole portion (not shown) of shoe (not shown).
In operation, base plate 2 of the preferred length and material are fastened to the bottom of a shoe (not shown), for the particular sport for which the shoes will be utilized.
One embodiment of the removable cleat 1 includes the base plate 2 having a series of conventional long metal spikes (not shown) and the construction of such metal spikes (not shown) is well known.
Another embodiment removable cleat 1 includes the base plate 2 having a series of conventional soft golf spikes (not shown) and the construction of such soft golf spikes (not shown) is well known.
One embodiment of the removable cleat 1 includes a removable base plate 2 with numerous fixed spikes (not shown) that allows the removal of the removable cleat 1 but does not allow the removal or replacement of the numerous removable spikes (not shown). In general, it includes a base plate 2 having numerous spikes or soft spikes (not shown) affixed to the base plate 2 such that the numerous spikes or the soft spikes (not shown) are securely fixed to the base plate 2.
Typically the base plate 2 may be made of a plastic material such as ethylene vinyl acetate (EVA) or of a rubber material permitting resilient flexibility.
Another embodiment of the removable cleat 1 includes a removable base plate 2 with numerous removable spikes (not shown) that allows the removal of the removable cleat 1 and allows the individual removal and/or replacement of the numerous removable spikes (not shown). In general, it includes a base plate 2 having numerous appropriate holes for receiving a threaded male stem (not shown) of a spike or a soft spike (not shown) using an insertion tool. The base plate 2 is provided with numerous conventional threaded inserts (not shown) each having female threaded holes (not shown) for receiving stems (not shown). The receiving stems (not shown) of the removable spikes (not shown) are inserted into the female threaded hole (not shown) and rotated to secure them in the female threaded hole (not shown). The removable spikes (not shown) are further secured with the insertion tool.
As described briefly above, the wearer can apply each of the removable cleat 1 directly to the shoe by hand, when needed, by simply aligning the base plate 2 with appropriate size and shape of the shoe (not shown) and firmly pressing the surfaces together. Alternatively, the wearer can apply each of the removable cleat 1 while wearing the shoe (not shown) by positioning the base plate 2 on the ground surface and simply aligning the base plate 2 with appropriate size and shape of the shoe (not shown) and firmly stepping on to the base plate 2 and the surfaces together. This can be accomplished while standing or sitting, by raising each shoe (not shown) and overlying the sole portion (not shown) of the shoe (not shown) with the base plate 2 and stepping onto the base plate 2. Various alignment structures, such as side guides can be provided on the overlying sole to assist in aligning it with the base plate 2. Removal of the base plate 2 is the reverse of application of the base plate 2. In general, the user lifts up his or her foot and physically pulls the removable cleat 1 away from the sole portion (not shown) of the shoe (not shown).
The removable cleat 1 may also include a treaded bottom which allows it to further grip the surface, the removable cleat 1 may include rubber, foam and other surfaces and may be both patterned and unpatterned.
An adhesive layer 8 is positioned on the back of the base plate 2 to adhere the base plate 2 to the sole portion (not shown) of the shoe (not shown). The adhesive force is chosen based upon the strength of the actual adhesive used, and upon the amount and thickness of the adhesive used and their overall area of engagement to make the engagement between the base plate 2 and the shoe (not shown) sufficiently firm so that the sole will not become inadvertently removed during use, but weak enough to allow a pulling hand applying sufficient force to remove the base plate 2 from the shoe (not shown) when desired. In addition, the adhesive can be applied to the entire surface of the base plate 2 or a portion of the base plate 2. Other embodiments may use pressure-sensitive adhesives in conjunction with other mechanisms to secure the base plate 2 to the shoe (not shown). It is contemplated in alternative embodiments that adhesive can be substituted or enhanced with hook and loop fasteners, and polymers.
The adhesive layer 8 includes an adhesive used with the present invention which may include ABS cement, acrylic cement, balsa cement, cyanoacrylate, epoxy resin, polyester and polyvinyl resin, PVA glue, chlorosulfonated polyethylene synthetic rubber or rubber glues, e.g., acrobutylstyrene cement is an emulsion containing ABS and a solvent (usually MEK). ABS cement will also glue acrylic and polystyrene; acrylic cement uses dichloromethane, trichloroethane, or butanone to weld acrylic surfaces together; balsa cement usually contains some sort of synthetic resin which bonds the surfaces together using as an adhesive rather than a weld; cyanoacrylate glue sets in seconds and are extremely strong; epoxy is very strong resin glue, and it is both waterproof and solvent-proof; polyvinyl and polyester resins are synthetic resins that need to be mixed with a catalyzing agent (hardener) before use; synthetic resins can be used as a casting agent and combined with other materials to form resin composites; and polyvinyl acetate glue; rubber based glues. The adhesive may include a water insoluble polymer comprising polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC) or an acrylonitrile butadiene-styrene polymer (ABS), or a mixture of two or more thereof. These adhesive compositions containing the water insoluble polymers generally are known in the industry and may be referred to herein as “solvent cements”. The amount of water insoluble polymers included in the adhesive compositions of the second embodiment depends in part on the particular water insoluble polymer and the intended use of the adhesive. In one embodiment, the adhesive compositions of the invention contains from about 1% to about 60% by weight of ABS, PVC, CPVC. In other embodiments, the adhesive compositions of the invention contain from about 1% to about 30% by weight or from about 10 to about 15% by weight of PVC, CPVC. In another embodiment the adhesive compositions may contain at least 5% of the water insoluble polymer. Non limiting adhesives include but are not limited to U.S. Pat. Nos. 8,399,091, 8,299,182, 7,473,753 the contents of each of which is incorporated herein by reference.
By adding the removable cleat 1 to the shoe (not shown), the shoe (not shown) may now be worn as a cleated shoe. Thus, the shoe (not shown) may be worn either with or without the removable cleat 1. When the removable cleat 1 is not on the shoe, (not shown) the shoe (not shown) may be used for day to day activities, and when the removable cleat 1 is added to the shoe, (not shown) it may be used for athletic competitions requiring spikes of cleats such as golf, soccer, baseball and football.
