Retractable spike golf shoe
US 3793751 A
Abstract
This invention relates to a retractable spike, particularly for a golf shoe and the like, whereby the spikes can be either protruded or retracted from the bottom sole of the shoe to protect the floor of a clubhouse or the turf on the green. This movement of the spikes can be accomplished from the outside of the shoe by a mere rotation of a protruding knob.

United States Patent 1191 11] 3,793,751 Gordos Feb. 26, 1974 [54] RETRACTABLE SPIKE GOLF SHOE 3,281,971 11/1966 Woitzner 36/25 R [76] Inventor: Ambrose L. Gordos, 4301 E. 2nd FOREIGN PATENTS OR APPLICATIONS St., Apt. 1E, Long Beach, Calif. 626,663 2/1936 Germany 36/61 90803 [22] Filed: Apr. 5, 1971 Primary Examiner-Patrick D. Lawson [21] Appl. No.: 131,292

[57] ABSTRACT 52 us. c1. 36/61, 36/25 AH This invention relates to a retractable spike, particu- 51 1m. 01 A43C 15/00, A43b 00/00 larly for a golf Shoe and the like, whereby the spikes 5 m f 3 5 R, 5 AH, 5 R 61, can be either protruded-or retracted from the bottom 3 2 sole of the shoe to protect the floor of a clubhouse or the turf on the green. This movement of the spikes can 5 References i d be accomplished from the outside of the shoe by a mere rotation Of a protruding knob; l,361,078 12/1920 Lynn 36/61 3 Claims, 5 Drawing Figures RETRACTABLE SPIKE GOLF SHOE An object of my invention is to provide a novel retracting spike means which can be readily actuated by the user upon rotation of a protruding knob at the heel of the shoe. The protruding knob rotates a cam shaft journaled in a recess in the sole of the shoe.

Another object of my invention is to provide a cam shaft which is flexible to permit flexing of the foot of the user, thus providing a more comfortable shoe.

Still another object is to provide a retractable spike structure for a golf shoe which is simple in construction and inexpensive to manufacture.

Other objects, advantages and features of invention may appear from the accompanying drawing, the sub- I joined detailed description and the appended claims.

In the drawings: FIG. 1 is a perspective view of a my invention.

FIG. 2 is a sectional view taken on line 2-2 of FIG.

golf shoe embodying FIG. 3 is a sectional view taken on line 3-3 of FIG. 2.

FIG. 4 is a view similar to FIG. 3 but spikes in retracted position.

FIG. 5 is a fragmentary sectional view taken on line 55 of FIG. 3.

Referring more particularly to the drawing, the numeral 1 indicates a golf shoe which includes the usual sole 2 which is the usual shape, although somewhat showing the thicker than commonly employedand inlcudes the customary parts of a sole, as will be subsequently described. The sole 2 includes an inner lining 3 and an outer layer 4 which is spaced from the inner lining 3 to provide a space 5 in which theoperating mechanism is placed, as will be subsequently described. A cam shaft 6 extends longitudinally through the space 5 and this cam shaft is journaled in a bearing 7 at the toe of the shoe, and a bearing 8 at the rear of the shoe. A flexible sleeve 9 is provided at the instep of the shoe 1 and is fixedly mounted in the shaft 6, but allows flexing of the shaft to permit flexing of the shoe while the user is walking. A knob 10 is provided at the rear end of the shaft 6 and protrudes from the heel of the shoe so that the cam shaft 6 may be manually rotated by the user to extend and retract the spikes, as will be subsequently described.

A spike plate 11 is positioned in the space 5 and extends from approximately the instep of the shoe to the toe. A plurality of spikes 12 extend from the plate 11 and project through aligned holes 13 when the spikes are extended. A plurality of straps 14 are attached to the upper surface of the plate 11 and extend over the cam shaft 6 and engage the cam shaft so that the plate 11 and the spikes l2 thereon may be moved vertically within the space 5 to extend or retract the spikes 12.

2 A heel plate 15 is positioned in the space 5 and at the heel of the shoe, and this heel plate carries a plurality of spikes 16 which protrude downwardly and project through appropriate holes 17 in the heel when the spikes-are in use. An operating strap 18 is provided on the heel plate 15 and loops over the cam shaft 6 so that the heel plate 16 will be raised and lowered vertically as the cam shaft 6 is manually rotated. This causes the heel spikes 16 to raise or lower as required by the user.

IN OPERATION The user rotates the knob 10 to, in turn, rotate the cam shaft 6, which will raise or lower the plates 11 and 15 simultaneously to extend or retract the spikes l2 and 16, as required by the user.

Having described my invention, I claim:

1. A retractable spike for a golf shoe comprising a sole on said shoe, a liner in said shoe spaced from the sole to form a space in the shoe above said sole, spike mounting means in said space, and spikes protruding from said mounting means, said sole having holes therein through which said spikes protrude in one position of the parts, and manually operable means connected to said mounting means to actuate said mounting means and motivate said spikes to protrude and retract said spikes, said spike mounting means comprising a plate, said plate being reciprocally mounted in said space.

2. A retractable spike for a golf shoe comprising a sole on said shoe, a liner in said shoe spaced from the sole to form a space in the-shoe above said sole, spike mounting means in said space, and spikes protruding from said mounting means, said sole having holes therein through which said spikes protrude in one position of the parts, and manually operable means connected to said mounting means to actuate said mount- 7 ing means and motivate said spikes to protrude and retract said spikes, said manually operable means comprising a cam shaft extending into said space.

3. A retractable spike for a golf shoe comprising a sole on said shoe,'a liner in said shoe spaced from the sole to form a space in the shoe above said sole, spike mounting means in said space, and spikes protruding from said mounting means, said sole having holes therein through which said spikes protrude in one position of the parts, and manually operable means connected to said mounting means to actuate said mounting means and motivate said spikes to protrude and retract said spikes, said spike mounting means comprising a plate, said plate being reciprocally mounted in said space, said manually operable means comprising a cam shaft extending in to said space, and a strap on the plate engaged by .the cam shaft. k =I I
