GOLF SPIKE'RECEPTACLES AND ANCHOR PLATE COMBINATION Filed March 17, 1965 52 1s 12 3e f f 2o Y M NL F E. 4 O 'I Haai/v eomgxu @www United States Patent M 3,237,323 GOLF SPIKE RECEPTACLES AND ANCI-IOR PLATE COMBINATION Arden B. MacNeill, Waltham, Mass., assiguor to MacNeill Engineering Company, Inc., Waltham, Mass., a corporation of Massachusetts Filed Mar. 17, 1965, Ser. No. 440,420 4 Claims. (Cl. 36-59) This invention relates to the combination of golf spike receptacles and receptacle retaining plates for assembly in shoe soles and more particularly to an improved combination of golf spike receptacles and receptacle retaining plate having a peripheral configuration of a shoe half-sole with a toe and shank sections and a narrow land therebetween flexibly holdi-ng the sections together as a unitary structure for facilitating manufacture and assembly in shoe soles.
A serious problem in the use of metal plates in shoe soles for holding golf spike receptacles is that the metal plates tend to stiffen the sole to a degree which undesira'bly impedes sole flexure caused by a foot during walking. This stiffening affect is particularly objectionable at the position of sole contact with the ball of the foot where maximum sole flexure occurs. One method of minimizing this flexural impedance problem might be to use two golf spike receptacle retaining'plates, one receptacle retaining plate covering the toe section of the sole located forward of the line of maximum sole lleXure, and the other receptacle retaining plate covering the shank section located behind the line of maximum sole flexure. However, such dual golf spike receptacle retaining plates create problems of inefliciency, inconvenience and increased costs in manufacture of the separate receptacle and retaining plate combinations, as well as inefficiency, inconvenience and increased costs of their assembly in shoe soles. Also, inasmuch as different sizes of receptacle retaining plates are required to accommodate the different sizes of shoe soles, the dual receptacle retaining plate construction creates the further problem of possible mixing of element sizes and proper mating of the receptacle retaining plate components for each particular shoe size.
These problems have been overcome by the present invention of an improved combination of golf spike receptacles and receptacle retaining plate which also incorporates other desirable features and advantages. Among these other desirable features and advantages of the present invention include that of the use of a single golf spike retaining plate construction conforming to the peripheral shape of a shoe half sole and anchoring all of the golf spike receptacles in place at the bottom of the sole without materially impeding flexure of the sole at the line where maximum sole flexure normally occurs. Other features and advantages including achieving convenience and economy production of a golf spike receptacle retaining plate as a single, unitary memiber as well as the advantages of a single, unitary member for handling, storing and assembling in the soles of shoes. A further feature and advantage is that of achieving a unitary receptacle retaining plate construction which is usable for the soles of both the right and left feet and which is producible as an inexpensive high production rate stamped product.
A primary object of the present invention is the provision of a combination of a plurality of golf spike receptacles and a receptacle retaining sole plate as a unitary structure for carrying all of the golf spikes in a shoe sole without substantially impeding llexure of the sole at the line in the sole Where maximum walking llexure occurs.
Another object is the provision of a golf spike receptacle retaining sole plate having capacity for anchoring sufficient golf spike receptacles to accommodate all of the 3,237,323 Patented Mar. 1, 1966 ICC golf spikes at the bottom of a shoe sole without substantial impairment of flexure of the sole resulting from walking therewith by a wearer of the shoe.
Further objects include the provision of a golf spike receptacle anchoring plate which is adaptable for both the right and left shoe soles, lends itself to inexpensive mass production, is readily assembled in the soles of s'hoes as a single unitary str-ucture with only one of said unitary structures being needed per shoe sole for carry-ing the entire golf spike requirement of said sole and without impeding desirable flexural characteristics of the sole.
These objects, features and advantages are achieved generally by the provision of a thin, metallic plate having a peripheral co-nfiguration of a shoe half-sole with a top and bottom surfaces and with a peripheral configuration having oppositely disposed toe and shank ends and oppositely disposed inner and outer side sole conforming contours includin-g a portion defining the area receiving the ball of a foot, a plurality of fastening structures in the metallic plate for receiving and firmly fastening to the plate a plurality of golf spike receptacles, and a pair of elongated openings extending inwardly from the inner and outer peripheral contours at the area receiving the ball of the foot for thereby forming a toe and shank sections of the anchoring plate with a narrow land therebetween for flexibly holding the toe and shank sections in proper physical relation to each other as a single, unitary structure for convenience and efficiency in manufacture of the combination and assembly in shoe soles.
By making the fastening structures in the form of groups of holes with each group comprised of a circular hole between a pair of elongated slots, with the circular hole carrying a threaded sleeve and the slots carrying respective ears of an associated golf spike receptacle,`a relatively simple, inexpensive and secure fastening arrangement for the golf spike receptacles to the retaining plate is thereby achieved.
By making the metallic plates of spring tempered carbon steel or stainless steel, a very thin material having high flexure characteristics as well as desirable resistance to cracking under repetitive llexure is thereby achieved.
By providing in some of the fastening structures a single circular hole and single elongated slot with the sleeve of the golf spike receptacle in the circular hole and one of the receptacle ears in the slot with the other receptacle ear folded about the peripheral contour of the retaining plate, Wider choice of receptacle placement on the plate is thereby achieved.
These and other objects, features and advantages of the invention will be 'better understood from the fol-lowing description taken in connection with the accompanying drawings of a preferred embodiment of the invention and wherein:
FIG. 1 is a plan view of a combination of golf spike receptacles and receptacle anchoring plate in accordance with the present invention;
FIG. 2 is a bottom view of the FIG. 1 embodiment;
FIG. 3 is `a side view taken on line 3 3 of FIG. 1;
FIG. 4 is a cross sectional view to enlarged scale of a portion of a shoe sole with the FIG. 1 embodiment assembled therein and shown in cross section taken on line 4 4 of FIG. 1.
Referring to the drawings in more detail, a combination of golf spike receptacles and a thin :metallic receptacle retaining or anchor plate in accordance with the present invention is designated generally by the numeral 10. The combination 10 has a thin metallic golf spike receptacle retaining or anchor plate 12 preferably of such material as spring tempered carbon steel or stainless steel and a thickness in the order of .0'15 of an inch. The golf spike receptacle retaining plate 12 has a peripheral configuration 14 of a shoe half-sole with a top surface 16 and bottom surface 18. The peripheral configuration 14 has oppositely disposed toe and shank ends 20 and 22 respectively, and oppositely disposed inner and outer side sole conforming contours 24 and 26 respectively which include portions 28 and 30 respectively between which is an area for supporting the ball of a foot (not shown) and across which maximum flexure perpendicular to the receptacle retaining plate 12 occurs during walking.
The golf spike receptacle retaining plate 12 at the portions 28 and 30 has oppositely disposed, inwardly extending openings or slots 32 and 34 respectively along a line of said maximum flexure and form-ing thereby substantially separate toe and shank sections 36 and 38 respectively with only a narrow land 4t) of the thin metallic plate 12 material for flexibly holding the toe and shank sections 34 and 36 in proper physical relation to each other as a single, unitary structure for ease in manufacture as a single, relatively simple, high production stamping operation and ease in assembly as will be hereinafter further described. The narrow land 40 while achie-ving the above described unitary structure nevertheless offers substantially no resistance to flexure.
The golf spike receptacle retaining plate 12 is provided with a plurality of groups of holes or openings therethrough with each group comprising a circular fopening y42 between a pair of narrow elongated openings or slots 44 and 46 respectively at selected positions in the plate 12 for anchoring golf spike receptacles 48 thereto. The golf spike receptacles `48 each include an internally threaded sleeve 50' projecting downwardly of the bottom surface 18 through the circular hole 42 with the upper end of the sleeve 50 having a flare or flange 52 resting on the top surface 16 of the plate 12 and having oppositely disposed ears 54 and 56 extending through the slots 44 and 46 respectively and bent over to engage the bottom surface 18 of the plate 12 for thereby holding the respective golf spike receptacles 48 securely in place on the retaining plate 12.
To facilitate greater `freedom in placement of the golf spike receptacles 48 on the retaining plate 12, some groups of fastening holes may include only a single circular ho-le 42 and a single elongated slot 44 for receiving a receptacle sleeve 50 and ear 54 respectively ywith the other ear 56 being lbent about the peripheral configuration 14 of the retaining plate 12 as shown at the toe end 20 and shank end 22.
The combined lgolf spike receptacles 48 and receptacle retaining plate 12 is assembled in soles 58 of shoes (not shown) preferably bet-Ween an outer sole 60 having holes therethrough such as hole 62 aligned with and receiving corresponding ones of the `golf spike receptacle sleeves 50, and an intermediate sole 64 covering the top surface 16 of the receptacle retaining plate 12 Iwith an inner sole 66 as is customary in shoe sole construction. The threaded Shanks such as shank 68 of golf spikes such as golf spike 70 are inserted through the holes 62 from the bottom of the outer sole 58 and screwed tightly into the internally threaded sleeves 50 of the gol-f spike receptacles 48 and thereby anchoring the golf spikes 70 securely in place under the shoe sole 60 with capacity for withstanding heavy load conditions on the golf spikes 70.
It will be noted from FIG. 4 that the land 40 being is not dependent for its strength on the land 40, an eventual exurally caused crack in the land 4i) will not detract from the use or comfort, or golf spike retaining service of the toe and shank sections 36 and 38 respectively of the retaining plate 12.
It should also -be noted that inasmuch as receptacle retaining plate 12 will have the same peripheral configuration 14 for both the right and left soles 58, the deter- -minat-ion of its use for either the right or left sole is made by the direction faced by the threaded sleeves 50. For example, in FIG. 1 the receptacle sleeves 50 are projecting outwardly from the bottom surface 18 of the plate 12 thereby making the combination one for a left sole. Reversing the direction of the sleeves 50 so that they project outwardly from the top surface 16 of the plate 12 would make the combination one for a right sole.
This invention is not limited to the particular details of construction described a-s equivalents will suggest themselves to those skilled in the art.
