BACKGROUND OF THE INVENTION
Technical Field. This invention generally relates to cleat devices for shoes. More particularly, this inven-tion relates to detachable cleats or "spikes" for golf shoes which are suitable for winter play.
Backqround Art. During the winter months, some greens keepers of golf courses prohibit the use of standard metal golf shoe spikes because of their detrimental effect on the fairways and greens of the golf course. This is especially true in the northern states where the dormancy period of grass can exceed six to nine months.
Many avid golf ers continue golf ing regularly through-out the winter months, even though they cannot use spikes.
Until the instant invention, the only alternative for winter golfers who usually wear spikes has ~een to wear tennis shoes which do not damage the golf course. Besides CA 02208198 1997-08-0~
the problem of not providing sufficient traction to the golfer, this tennis shoes approach requires an additional investment by the golfer in a second pair of shoes.
Fig. 1 of the drawings shows a typical prior art metal spiked golf shoe, which is there denoted as 1. A plural-ity of metal spikes 4 are attached to the sole 2 of golf shoe 1. Each metal spike 4 includes a molded unitary body 5 having a disk-shaped flange 7, and a threaded stud 9 formed on the upper surface of the flange. A pointed protuberance, or spike, 6 is formed on the bottom surface of the flange to provide traction for the wearer. A pair of installation tool engagement holes 8 are provided at diametrically opposing points in the bottom surface of flange 7 to facilitate the threaded engagement of the threaded studs 9 in each threaded hole 3 within the sole 2 of golf shoe 1.
A similar replaceable cleat golf shoe i6 taught in REDDIEN, U.S. Patent No. 4,330,950. This patent teaches manufacturing the cleats from a non-conducting material to prevent the spikes from acting as an electrical connection to ground in the case of an electrical storm.
JORDAN, U.S. Patent No. 3,583,082 teaches a removable track shoe cleat for use on synthetic type surfaces which incorporates a plurality of bristles protruding from the traction surface of each individual cleat or spike.
What is needed is a replaceable cleat or spike for use in place of a standard metal spike for a golf shoe which does not cause damage to the golf course, especially in inclement or cold weather. Accordingly, one of the ob-jects of the instant invention is to provide a spike whichsatisfies this need.
A second object of this invention is to provide a removable athletic shoe cleat in the shape of a disk-like CA 02208198 1997-08-0~
flange having ridges integrally formed therein and extend-ing down from the bottom surface, and a threaded stud extending axially up from the upper surface of the disk-like flange. Other objects are to provide an upper sur-face to the disk-like flange which is either concave, dimpled, or sized to interfit into a recess in the shoe sole. Other objects are to provide a bottom surface of the disk-like flange which is convex. Further objects are to provide for a shoe cleat, as set forth above, wherein the ridges that are integrally formed in the bottom sur-face of the flange are either rectangular in cross sec-tion, triangular in cross section, arcuate in cross sec-tion, or radially extending from the center.
DISCLOSURE OF INVENTION
These objects, along with others, are accomplished by a replaceable cleat formed of a thermoplastic or similar material. The cleat has a plurality of ribs on the trac-tion surface in place of standard pointed protuberances.
The cleat is formed generally in a unitary body having a threaded stud axially protruding from the upper surface of a generally concavo-convex flange from the perspective of sole 2. The ribs may be present in a variety of configu-rations, and may be formed with an arcuate, tria~lar or rect ~ ar cross section.

BEST MODE FOR CARRYING OUT INVENTION
Referring again to the Figures, our winter golf shoe spike 10 is illustrated in detail in Figs. 2 - 6. Golf shoe spike 10 generally has a main cleat body 11 molded or otherwise formed of durable plastic material which is advantageously the same material used to manufacture the sole 2 of golf shoe 1. It should be noted that spike 10 may be manufactured from any suitable material or combina-tion thereof, and it may easily be assembled from two or more separate pieces. For instance, the threaded stud 13, explained below, may be manufactured from a metal material such as aluminum, while the remainder of the cleat body 11 may be made of a synthetic plastic material.
Preferably, however, the main cleat body 11 is molded from a durable plastic type material in single unitary fashion. The cleat body 11 is preferably made from a plastic material which is also very resilient, even in temperatures below about 0~C. This way, the cleat main-tains its resiliency for traction, and for protection of the turf, in cold weather. A preferred material for our cleat is polyether block urethane, available as Estane~
from B.F. Goodrich Co.
A threaded stud 13 is formed on the upper surface of generally concavo-convex flange 12 and protrudes axially therefrom. The threads on threaded stud 13 are sized to -CA 02208198 1997-08-0~
cooperate with the female threads of the threaded hole 3 in the sole 2 of golf shoe 1.
Threaded stud 13 may be a different cleat attachment means in other embodiments. For example, stud 13 may be a tipped prong that relies on a reversible snap-fit engage-ment with a slot or rim in hole 3. For now, however, we prefer the threaded stud for its firm and strong engage-ment with hole 3.
Optionally, the concave upper surface of flange 12 may be roughened, dimpled or furrowed to increase the friction between it and sole 2 when the cleat body 11 is tightened in position against the sole. Also, the concave feature of the upper surface tends to create more of a sharp edge there on the perimeter of the flange 12 for a firmer engagement with sole 2. Also, the concave feature of the upper surface tends to create a disc spring effect on cleat body 11 when threaded stud 13 is run into threaded hole 3 and tightened. This way, there is tension placed on stud 13, and its threads bind more securely with those of hole 3.
There is a slight recess provided in many golf shoe styles in 801e 2 for a short annular distance around hole 3. For these styles, the flange 12 may be advantageously sized to fit snugly within the annular recess, thereby providing an ever firmer fit.
A plurality of traction ribs 15 are formed on the bottom traction surface of generally concavo-convex flange 12. While the ribs 15 may be present in a variety of configurations, preferably they are arranged in a radial fashion emanating from near the center of concavo-convex flange 12. The cross sectional shape of ribs 15 may be arcuate, triangular, rectangular or a combination thereof.
Preferably, ribs 15 are triangular, but with rounded edges . CA 02208198 1997-08-05 . . .
to provide the best compromise between traction and damage to the turf.
By "generally concavo-convex from the perspective of sole 2" we mean that flange 12 bends slightly away from sole 2 at both its upper and its lower surfaces. These bends, however, may be different and they may be very 61ight. The upper bend aids in securely engaging the cleat body 11 to the shoe sole 2 as disclosed above. The lower bend aids in enlarging the surface area of the cleat ,"
to provide more room for traction ribs 15, and to provide more surface area over which to distribute the weight of the golfer, two goals of our invention. The ~;mum lower bend would be for a hemispherical cleat, but we prefer one less pronounced than that, about one-half hemispherical.
This way, the cleat is not so pronounced, and it does not do so much damage to the turf. The minimum lower bend would be for a flat cleat, but we prefer one more pro-nounced than that. This way, there is more angle on the sides of the cleat surface, and the ribs there are pre-~ented to the turf more aggressively for more traction.
By "flange" we mean a projecting rim or collar around threaded steel 13 to form a disk-like structure. This wayl the flange 12 i6 relatively thin and the length of cleat body 11 from the flange's upper surface to the bottom of ribs 15 is not great, preferably about 0.25 or less. The flange may be circular, square, rectangular, or any other shape. Most common shoe styles are designed for circular cleat flanges.
By "ribs" we mean more than one vertical ridges in the bottom surface of flange 12. The ridges have a crest that is at least one line, compared to the crest of the prior art spikes which are a point or a circle (for a truncated cone, for example). Preferably, the ridges are about as , ;
~ . .
wide at their base as they are high. The ridges may be straight or curved and they may be chords, diameters, or radii of the bottom surface of the disk-like flange 12. Preferably, the ridges are between about 0.03125" and 0.125" high.
Optionally, a pair of installation tool engagement holes 14 are provided at diametrically opposing points in the bottom surface of flange 12. The conventional instal-lation tool has two prongs which fit into engagement holes 14, plus a shaft and a handle like a screwdriver to help impart rotary motion to cleat body 11. This way, the cleat body 11 may be conveniently driven in and out of the threaded hole 3 on threaded stud 13, and securely tighten-ed in the in position against sole 2.
lS In use, the golfer simply removes the metal cleats on his or her golf shoes with the installation tool and replaces the metal cleats with the winter golf shoe spikes 10 of the instant invention.
While there is shown and de~cribed the present pre-ferred embodiment of the invention, it i6 to be distinctly understood that this invention i6 not limited thereto, but may be variously embodied to practice within the scope of the following claims.
