SPIKE FOR SHOES Filed March 18. 1966 INVENTOR United States Patent 3,423,855 SPIKE FOR SHOES Yosliiaki Kosono, 30 Asakusa-Slroten-cho, Taito-ku, Tokyo, Japan Filed Mar. 18, 1966, Ser. No. 535,574 Claims priority, application Japan, Mar. 22, 1965,
40/ 16,594 US. CI. 36-67 Claims Int. Cl. A44b 21/00; A43c /16 ABSTRACT OF THE DISCLOSURE The present invention relates to a spike for golf shoes and a manufacturing method thereof.
Heretofore, the construction of a conventional spike for golf shoes consists of a screw-axis member which is screwed into the bottom part of the shoes, a flange part which stops the aforesaid screw-axis member from going in too far and a pin extending from the bottom surface of the aforesaid flange part. Both the screw-axis member and the flange part are provided with one metal pole and the flange is made of either metal or plastic for fixing in between the screw-axis member and the pin.
Accordingly, the manufacturing process for such a conventional spike naturally requires several complicated steps because the screw-axis member and the pin are manufactured from one metal plate material by means of a press-treatment, while the flange part is fixed thereafter; and besides, the flange part is, sometimes, made of plastic material in order to be light in weight, although no considerable weight reduction is effected from such a process.
It is an object of the present invention to provide a spike for golf shoes and a method of manufacturing the same, which spike is simpler than heretofore due to a manufacturing process in which the golf shoe spike comprises a screw-axis member, a pin and a flange part completely formed with one metal plate. Consequently, the prior art process for forming the flange part in a separate step can be now avoided, which directly results in easier and more substantial production, and in addition, the weight problem of the conventional spike may be solved.
With this and other objects in view which will become apparent in the following detailed description, the present invention will be clearly understood in connection with the accompanying drawing, in which:
FIGURE 1 is a perspective view of one embodiment of the present golf shoe spike;
FIG. 2 is an elevational view and in part a section along the lines 2-2 of FIG. 1 before the axis members are cut or pressed upwardly;
FIG. 3 is a section along the lines 2-2 of FIG. 1 after the axis members are pressed upwardly;
FIG. 4 is a top plan view of FIG. 3;
FIG. 5 is a perspective view of another embodiment of the spike in accordance with the present invention;
FIG. 6 is a section along the lines 66 of FIG. 5;
FIG. 7 is a top plan view of FIG. 6; and
FIG. 8 is an axial sectional view of a screw illustrating a screw forming process.
Referring now to the drawing, first a flange 1 is formed 'from a metal plate and then a hollow pin 2 is centrally formed by a conventional press-method operation such as pressing a pin formation out of the metal plate by pressing the plate with a pin-shaped die press, so that the hollow pin 2 extends integrally from the plane and to one side of the plate. Also a recessed surface 3 of the flange 1 is formed (FIG. 2) and the strength of the flange 1 is remarkably improved. The strength of the pin 2 is satisfactory as it is formed by the pressing or squeezing process. The shape of the flange and/or the sectional shape of the pin is not limited to circular shapes, square shape being available, for example. In the next step, a hollow axis screw member 4 is formed by cutting out at least two tabs 5 angularly spaced apart from each other, such as, for example, two opposed portions 5 of the surface of the flange 1 and then pressing the same in an upward direction opposite to that of the pointing of the pin. As illustrated in FIGS. 4 and 7, the member 4 is formed by the two portions or tabs 5 which with the base portion of each tab 5 define a juncture with the base portion 5 of the pin 2 and are pressed out and bent out of and to the other side of the flange 1 coaxially relative to the hollow pin 2 and these upwardly bent tabs 4 have opposed concave faces defining a generally cylindrical axis member 5, in diameter so as to be substantially cylindrical; such a member may also be made with three or more pieces if the strength of the flange permits. The vertically upwardly extending pieces 5 constitute axis member 4 and cooperate with each other and are formed with a male-screw thread on, for example, the outer-circumference or surface thereof '(FIGS. 1 and 5). The formation of the circular projection on the surface of the flange 1 may be constructed either when pieces 5 are pressed out, upwardly, or afterwards.
Since there are spaces between the longitudinal or side edges of the pieces 5, the member 4 may be divided in the axial direction as shown in FIGS. 1 to 4; however, the member 4 can be made into a perfect circular shape by closing these spaces and connecting the longitudinal edges. In this embodiment, the base part 5' or juncture of the tabs 4 with the pin 2, is frustoconical in shape from bottom to top in an inwardly direction as shown in FIG. 6. Accordingly, an eflicient spike having satisfactory strength for the member 4 and for the connecting part of the flange 1, shown in FIGS. 5 and 7, is obtained.
Referring now again to the drawing, and more particularly to FIG. 8, there is illustrated a screw member 4 pressed by screw dies b from the outer circumference incorporating an inner die member a, forming on the outer surface of the member 4, the male screw threads 6. For inserting the screw member 4 into the bottom part of the golf shoe, a proper tool is used.
In case a driver is used for such an insertion operation, receptacle holes may be provided on the surface of the flange 1, and the bottom end of the spike must be reformed when a spanner is used as a tool. The aforementioned holes or reformation of the bottom end of the spike are formed simultaneously with the pressing out of the pin. Further, the holes 7 in the flange 1, formed when pressing out pieces 5 from the surface of the flange 1 for forming the screw member 4 may be adapted to be utilized as tool connecting holes.
In order to provide the pin 2 with an anticorrosive characteristic, either a tempering process or a covering process with an ultrahard metal 8 may be applied (FIG. 6).
The golf shoe spike of the present invention may be manufactured from a thin metal plate and is light weight due to the hollow construction of both the pin and the screw member.
Further, the pin or spike has sufficient strength and is durable due to the single body construction thereof, particularly processed by the pressing step in which the pin is squeezed or pressed out from the flange and the screw member 4 is projected upwardly in an opposite direction to the pin. Furthermore, the manufacturing process of the present invention is simplified with the process steps of squeezing and pressing which two steps are readily and easily performed and constitute the main manufacturing steps, and after being performed substantially leave little more in time or effort for the completed product.
While I have disclosed several embodiments of the present invention it is to be understood that these embodiments are given by example only and not in a limiting sense, the scope of the present invention being deterrn-ned by the objects and the claims.
What I claim is:
1. A spike for golf shoes comprising a metal plate having a central portion extending integrally from the plane of and to one side of said plate defining a hollow pin and a flange surrounding said pin,
an axis member comprising at least two tabs angularly spaced apart from each other cut out from said flange with the base portion of each tab defining a juncture with the base portion of said pin,
said tabs being bent out of and to the other side of said flange coaxially with said pin, and
said upwardly bent tabs having opposed concave faces defining a generally cylindrical axis member with one of the surfaces thereof having screw threads thereon.
2. The spikes, as set forth in claim 1, wherein the side edges of said tabs are spaced from each other.
3. The spike, as set forth in claim 1, further comprising a metal plate covering said pin with said covering being of harder material than the material of said pin.
4. The spike, as set forth in claim 1, wherein the side edges of said tabs are joined to one another defining a substantially hollow cylinder, and
the juncture of said tabs with said pin being frustoconical in shape.
5. The spike, as set forth in claim 1, wherein said axis member is formed substantially into a hollow cylinder.
