United States Patent 3,492,744 GOLF SHOE AND BOTTOM THEREFOR Louis E. Bernier, Rockland, and James P. Giblin, Milton,

Mass, assignors to E. T. Wright 8: Co., Inc., Rockland,

Mass, a corporation of Massachusetts Filed May 9, 1968, Ser. No. 727,819 Int. Cl. A43c 15/02 U.S. Cl. 36-59 22 Claims ABSTRACT OF THE DISCLOSURE A golf shoe and bottom therefor provided with cleats anchored to an insert corresponding substantially in shape to the part of the bottom of the shoe with which it is to be used, said insert being incorporated in the bottom between the outsole and the insole with the cleats extending through holes in the outsole, and said cleats being comprised of a metal hard enough to last for the approximate life of the shoe without replacement.

BACKGROUND OF THE INVENTION Golf shoes provided with metal cleats are disclosed in U.S. Patents 3,204,347, 2,918,733, 2,784,503 and 3,337,971. The primary consideration disclosed in these patents was to provide a structure which would enable anchoring threaded sockets to the bottoms of shoes for removably receiving cleats provided with threaded portions for engagement with the threaded socket and to prevent the cleats from becoming loose during use. The purpose of the present invention is to provide a bottom structure such that the cleats are permanently attached and will remain effective approximately throughout the life of the shoe; to provide an insert which can be easily incorporated in the bottom of substantially any kind of shoe, whether hand-made or machine made or whether comprised of natural or man-made materials; to provide a cleated bottom in which only the ground-engaging portions of the cleats extend from the tread surface so that there is minimum disturbance of the turf and minimum caking; to provide a cleated bottom in which the inserts to which the cleats are attached are dimensionally stable pliant platforms which not only afford foot stability but also absorb local disturbances of the bottom caused by contact of the cleats with hard or firm objects; and to provide a cleated bottom in which there is substantially no possibility of dirt and/or water entering around the cleats into the internal structure of the bottom.

SUMMARY As herein illustrated, the shoe has a composite bottom provided with cleats comprising an outsole having a tread surface from which projects a plurality of cleats, each cleat having a portion extending inwardly from the tread surface and an insert disposed inwardly of the tread surface of the outsole to which the inwardly extending portions of the cleats are secured; characterized in that the insert has on the surface next to the outsole a plurality of bosses of relatively large diameter and the cleats have heads of smaller diameter than said bosses embedded therein. Inserts are provided for the forepart and heel ends of the shoe bottom and these correspond substantialy in shape to the area of the portion of the bottom in which they are to be incorporated. In a welt shoe, for example, the insert at the forepart of the shoe is lodged between the outsole and the insole in place of the conventional filler. In a flat lasted shoe, that is, a shoe in which the upper is wiped in over the outsole and cemented thereto, also known as a cement lasted shoe, the outsole is recessed to receive the insert. In a molded shoe the insert is embedded in the bottom.

3,492,744 Patented Feb. 3, 1970 If an elevated heel is employed the top lift is recessed to receive the insert or the lift next to the top lift is recessed to receive the insert and the top lift is provided with holes through which the cleats project. If the heel is formed by molding the insert will be embedded in the heel end of the shoe in the same fashion that the insert at the forepart is embedded in the outsole. Optionally, a cleated bottom unit may be made independently of the upper comprising a molded outsole and heel unit in which the inserts are embedded by injection molding or a molded outsole and heel unit containing cavities at the heel and forepart may be provided together with inserts adapted to be pressed into the cavity. The cleats comprise a shank portion of cylindrical right section, a circular head of relatively large diameter at one end and a tapered portion terminating in a tip at the other end. A hard wearresistant metal is provided at the tip by a core piece set into an axially extending socket in the tip end of the pin. The shank and heel are comprised of a softer metal.

The inserts for the forepart and heel each comprise a uniformly thick, dimensionally stable yet pliant platform of dense plastisol and integral bosses at one side in which are embeded the heads of the cleats.

The invention, as herein illustrated, relates to the manufacture of golf shoes and/or bottoms therefor provided with cleats, such shoes comprising, as shown in FIG. 1, an upper 10 of appropriate material and a bottom having a forepart 12 and heel 14, from the tread surfaces of which project cleats 16. The bottom structure which is illustrated herein with reference to welt, flat lasted and molded shoes is applicable to substantially all kinds of shoes whether hand or machine made and whether comprised of natural or man-made material.

In accordance with the invention inserts to which the cleats are attached are provided for incorporation in the bottom according to the type of shoe and these inserts comprise an insert 18 adapted to be incorporated in the bottom at the forepart and an insert 20 adapted to be incorporated into the bottom at the heel. Each insert, as shown in FIGS. 2 and 4, comprises a uniformly thick platform 18a, 20a which corresponds in shape to the part of the bottom of the shoe in which it is to be incorporated, from one side of which project a plurality of bosses 18b, 20b at places where the cleats are to be situated. The platform is approximately 4; inch thick and each boss is approximately of an inch in diameter and approximately A of an inch thick. The platform and bosses are formed integral, being comprised of plastisol and a cleat 16 is secured in each of the bosses.

The term plastisol employed herein is intended to embrace any and all natural and/or man-made elastomers suitable for the purpose. The platforms are comprised of a dense plastisol which is relatively hard and firm and yet is pliable.

Each cleat comprises a cylindrical shank portion 22, approximately of an inch in diameter; a circular head 24, approximately /2 inch in diameter and of an inch thick; and a conical portion 26 terminating in a tip 26a, the extremity of which is approximately of an inch in diameter. The conical portion 26 of the cleat is approximately of an inch long and contains an axial hole in which is set a core of very hard metal. The shank, head and tapered portions are comprised of a relatively soft metal. Preferably the core is a tungsten alloy and the remainder of the cleat a relatively soft steel. It is to be understood, however, that equivalent materials may be substituted therefor. It is also to be understood that the aforesaid dimensions of the cleats are by way of example, only, and may be varied so as to be consistent with the bottom structure in which they are to be incorporated, to provide for maximum wear, comfort to the wearer and minimum disturbance of the turf.

The cleats are secured to the inserts 18 and 20 by a process of injection molding in which they are held with their heads extending into a mold cavity and the plastisol or its equivalent, of which the inserts are to be comprised, is injected into the cavity around the heads of the cleats. The cleats are so supported that their heads are buried in the bosses 18b, 20b intermediate their upper and lower extremities as illustrated in FIG. 3. As thus incorporated the heads of the cleats all lie in a plane below the lower surface of the platform from which the bosses project.

Although the inserts 18 and 20 to which the cleats are secured are shown as separate pieces, it is within the scope of the invention to form the two pieces as a single piece, for example, for use in a shoe bottom without an elevated heel.

The inserts 18 and 20 or a single insert comprised of the inserts 18 and 20 may be employed for making golf shoes with leather bottoms or composition bottoms. By

way of example but without restriction there is shown in FIG. 9 a leather outsole containing at its inner side at the forepart a plurality of circular recesses 32a corresponding in diameter and thickness to the diameter and thickness of the bosses 18b on the platform 18a. At the center of each recess 32a there is a hole 34a which is slightly smaller in diameter than the cylindrical shank portion of the cleat. The insert 18 is placed against the inner side of the outsole, as shown fragmentarily in FIG. 11, with the bosses 18b fitted into the recesses 32a and with the cleats pressed through the holes 34a. Preferably a waterproof adhesive is applied to the surface portions of the inserts which will have contact with the inner surface of the outsole and to the surfaces of the bosses which will have contact with the interior surfaces of the recesses. The holes, as related above, are smaller in diameter than the cylindrical portions of the cleats so that pressure is required to force the cleats through these holes, thus providing a press-fit which effectively excludes water and dirt.

If an elevated heel is employed comprising several lifts, as shown in FIG. 15, the lift next to the top lift is provided with a recess 42b shaped to receive the insert and recesses 32a and holes 34b for receiving the bosses and cleats, and the top lift is provided with holes 340 through which the cleats extend. If a single lift is used, as shown in FIG. 15a, the top lift itself contains the recesses 42b, 32b and holes 34b. Optionally, the insert may correspond to the cross-section of the heel and may be substituted for the lift next to the top lift.

In welt shoes, such as illustrated in cross-section in FIG. 16, having an upper 10a, insole 36 and welt 38, there is a pronounced cavity 40 between the insole and the outsole which normally has to be filled with a filler, for example cork mastic, or the like. When making welt shoes the insert 18 may be substituted for the filler and thus in conjunction with the welt forms a fiat surface for receiving the outsole. Flat lasted shoes with or without insoles have a less pronounced cavity and accordingly it is desirable, as shown in FIG. 12, to provide the inner side of the outsole with a recess 42, in addition to the recesses 32a and holes 34a, which correspond in shape and thickness for receiving the platform, bosses and cleats. The recess 42 corresponds in shape and thickness to the platform 18a, the recesses 32a in diameter and thickness to the bosses and the diameters of the holes 3411 are somewhat smaller than the diameters of the cylindrical portions of the pins. FIG. 17 discloses a flat lasted shoe having an upper 10b, insole 44 and recessed outsole attached thereto. Such an outsole can be either leather or composition and the cavities, in the case of leather, may be formed by routing and in the case of composition by molding.

As related above, the heel may be provided with cleats by recessing the top lift or by recessing the lift next to the top lift and providing the top lift with holes, or optionally by replacing the lift next to the top lift by an insert corresponding in shape and cross-section to the heel.

If desired, the inserts 18 and 20 may be incorporated in a bottom formed and attached to an upper 10c by an injection molding process, as illustrated in FIG. 18, wherein the inserts 18 and 20 are completely enveloped in the bottom. Incorporation of the inserts 1'8 and 20 in the bottom may be effected in the same way as disclosed in our pending application Ser. No. 710,973, filed Mar. 6, 1968 and may comprise single layer or multiple layer construction.

Instead of forming the bottom directly to the bottom of a lasted upper which requires that the shoe manufacturer have injection molding equipment, bottom assemblies may be manufactured by manufacturers of soles and heels. For example, a composite bottom comprising an outsole and heel embodying at the forepart and heel inserts 18 and 20 may be made and supplied to the shoe manufacturer for cementing or otherwise fastening to a lasted upper. Optionally, the manufacturer may mold bottom units, with cavities 42, 42a at the forepart and heel end, and inserts 18 and 20 as shown in FIG. 19, and supply these components to the shoe manufacturer for use in making golf shoes, or he may make a composite bottom unit (FIGS. 20 and 21) embodying inserts 18 and 20 as an integral part thereof.

While injection molding is preferred in making such bottom units it is to be understood that these parts may be formed and/or joined by vulcanizing processes.

The heads of the cleats as shown contain peripherally thereof a plurality of notches 24a, the purpose of which is to provide an interlock between the plastisol and the head to prevent rotation of the head in the boss. Equivalent means may, of course, be employed for this purpose such as teeth at the peripheral edge, lugs or pins fixed to the upper and lower surfaces of the head, or holes or slots through the head, all of which provide radial shoulders.

The inserts 18 and 20 to which the cleats are attached provide a convenient means for incorporating cleats in all kinds of shoes with the advantage that the relatively thick platforms 18a, 20a from which the bosses extend afford a feeling of firm stability for the bottom of the foot and distribute the pressure at the heads of the cleats over a sutlicient area so that when the tip of any cleat or cleats strikes a hard surface or object it will not be displaced relative to the others toan extent to cause discomfort to the foot and hence the feeling of walking on spikes. In addition, the platform affords continuity throughout the entire forepart of the shoe so that there are no transverse gaps or shoulders which tend to leave the foot unsupported.

The cleats, as related above, are constructed of wearresistant alloy metal designed to last approximately throughout the normal life expectancy of the shoe itself thus avoiding the inconvenience of having to replace cleats which have become worn down and which very often, because of rusting or damage in use, become impossible to remove for the purpose of replacement.

As related above, the cleats are forced through the holes in the outsole and top lift of the heel which are smaller in diameter than the shank portions and waterproof adhesive is applied to the surfaces of the inserts and cleats and also to the portions of the outsole and heel lift with which the inserts and cleats will have contact, so that it is virtually impossible for moisture and dirt to gain access to the interior of the shoe around the cleats. Finally, because only the ground-engaging portions of the cleats extend from the tread surface of the bottom at the forepart and heel, that is because there are no surrounding metal ferrules or the like at the bottom, traction is afforded with the least amount of turf disturbance and with very little tendency to pick up moist soil so as to cause caking, a common fault of cleated shoes.

It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents falling within the scope of the appended claims.
