Abstract
Abstract An improved receptacle and spike assembly for athletic shoes is described. The spike assembly contains four fastening holes, and supports a spike and a connector. The improved receptacle is secured to a plate by embedding injectable material into cavities surrounding a suitable connector.

-2- 9790-3 shoe. Therefore, improvements have been made in -the spike assembly by using only a metal frame contiguous with the connector and spike, and embedding the metal frame into a plastic or nylon flange. In this version of the spike assembly, the lighter weight of the plastic or nylon results in a lighter shoe. One design of this modification utilizes a plastic thread on the male connector, as well, but this has proved clearly unsatisfactory due to inade-quate strength. Another design provides a metal male screw thread, and stabilizes the spike assembly by a series of three fan blade projections from the connector/spike. This design provides two keyholes for tightening the spike onto the receptacle, thus requiring large arc motions in tightening it down.
None of the foregoing designs is completely satisfactory.
The pronged receptacle relies on securing means which, because they bear directly against the surrounding material, often cause tearing and weakening of the soles and become loose. The metal flanged spike is unduly heavy; the plastic threaded connector, because of the weakness of the material, tends to strip; the tri-bladed assembly has an uneven weight distribution with respect to the two keyholes provlded to secure the spike. The present inven-tion overcomes these deficiencies.
Summary of the Invention The invention provides an improved receptacle for a golf spike assembly, which comprises: an annular, slightly concave, dish; a tubular, threaded, female connector disposed in the con-cave face of said dish and contiguous with the center thereof; and a series of cylindrical cavities disposed peripherally to the connector, extending through the thickness of the dish, and each ~3~

The receptacle is secured to the outer sole layer by injection oE molding in-to cavities of the receptacle, thus per-mitting the receptacle to be secured to an outer sole plate with-out the shear forces associated with the pronged receptacle. The golf spike assembly is light weight, is easily secured, and is highly reliable.
The connector being disposed on the concave side of the dish, will project outward from the sole of the shoe. Surrounding the connector, cylindrical cavities or circular perforations in the dish can accommodate injection molded plastic or nylon. The cap or "stopper" prevents excess material from being extruded from the outer face of the dish. These stoppers arej preferably, integral with the base of the dish.

The improved receptacle of the invention i~
shown in Figure6 lA and lB. Figure lA shows a facing view of the metal dish which contains at its center a protruding threaded connector, 101. The connector is surrounded by a ~eries of cavitie~ ~paced at positions equidi6tant from each other and from the center of the dish, a~ 6hown at 102. The dish is cut in an irregular pattern to minimize weight, ~ut other overall 6hapes, such, as a circular dish, are consistent with the invention.

The di6h i~ approximately 2-3 cm in its longest dimension, 104, and i~ approximately 1-3 mm thick, a6 shown at 105. The dimen6ion 105 need not be completely uniform acro~s the face of the dish. The cavitie6, 106, are '' ' '-- , .

These cavitie~ are mo~t conveniently formed by ~tamping the metal dish 80 that the stoppers are derived from the ~ame blank a~ the remainder of the ba~e. ~till referring to Figure lB, the connector, 101, i8 threaded internally, 107, 80 a~
to provide a receptacle connector with the ~pike a~sembly.
The receptacles shown in Figure 1 are mounted on the shoe by mean~ of a nylon or other ~ynthetic ~ole plate, a~ shown in Figures 2A and 2B. Figures 2A shows a suitable de~ign for the front portion of the sole, designed to bear seven receptacles at po~itions 201.
The heel plate in thi~ design is able to accommodate four receptacles at po6itions Z02 as shown in Figure 2B. The receptacle~ are secured to the plate~ by injection molding of the plate material into the capped cavitie6, 106. The molded projections thu~ maintain the integrity of the a~6embly, and because they do not rely on pun~turing the plate, as do traditional receptacles, the tendency of the plate ~o tear i~ le~s. The diameter of the cavitie6 de6igned to receive the injection mold is approximately 2-5 mm.

RePerriny to Figure 4, 401 show~ the ~pike projecting from the center of the Prame toward the viewer; not shown, but in the ~ame position - 30 away from the ~iewer on the other side of the frame i8 the threaded;male connector. The ~rame it~elP, 402, i8 approximately 2-3 cm in dia~eter, as shown at 403, and i8 approximatlely l-4 mm in thickness (dimension not shown). The periphery of the frame is provided with a :

In addition, the frame perforation6 contain perpendicular extensions at 405 to prevent movement of the frame within the assembly.
Po6ition 401 in Figure 4 corre~ponds to position 301 in Figures 3A and 3B. 3A and 3~ show the frame embedded~in the outer nylon dish, which provide~
the appropriate 6urface area and finish, but with less increase in weight than a metal analog. Figure 3B ~hows a 6ide view where the pike, 301, i6 indicated protruding from the convex facle of a curved nylon outer di6h: and the threaded connector projects from the concave face of thi6 dish. The dimension~ of the connector, 302, are matched to thosa of the receptacle, 6hown in Figure lB. Typically, the connector 302 has an outer diameter of 3 6 mm, and the inner diameter of the receptacle connec~or shown in lB at 107, has an inner dia~eter correspondin~ to this dimen6ion. Both connectors are about 0.4-1 cm long. The curved nylon ba~e, 303, separates the connector from the ~pike, a~
shown in Figure 3B.
