REPLACEABLE SPIKE FOR SHOES Filed Sept. 30, 1965 2 Sheets-Sheet 2 INVENTOR.

HENRY W. T RNER ATTORNEY.

United States Patent 3,267,593 REPLACEABLE SPIKE FOR SHOES Henry W. Turner, 29 Agatha Road, Revere, Mass. Filed Sept. 30, 1965, Bar. No. 496,236 4 Claims. (Cl. 3659) This invention relates to a replaceable spike for shoes. In particular, it relates to spikes as may 'be used on athletic shoes such as golf shoes and the like. Thisa continuation in part of my prior copending application, Serial Number 390,850, filed August 20, 1964. i

Replaceable spikes for shoes have been described in the past. Thus, U.S. Patent #19,205 issued in 1858 describes a heel-spur which is attached to the shoe by first permanently inserting a metallic socket in the heel. The interior of the socket is threaded so as to accept a threaded spur. This spur is intended to be either extended or retracted.

U.S. Patent #325,194 illustrates a driving calk for the sole of a boot. In this patent the receiving element driven into the sole of the shoe is tubular so that the threadable spike extends into the sole itself.

U.S. Patent #1,025,087 also describes a threadable spike inserted into a threadable open section of a plate on the inner surface of the sole in conjunction with a washer on the outer surface of the sole. A rivet extends between the washer and plate and contains the threaded receiving section.

U.S. Patent #1,435,872 describes a spike fastener in the form of an eyelet which is embedded in the sole and has its outer end flanged and bearing against the outer surface of the sole. The spike is threadably inserted into the eyelet with its shank in tight bearing contact with the inner surface of the sole. The spike in this case is also characterized as having a shoulder to engage the flange of the eyelet.

U.S. Patent 2,578,591 shows'a conventional golf spike having an anchor with threading and a spike with threading. Although its washer 10 may increase its strength, the threading arrangement in this Phillips patent lacks locking.

U.S. Patent 2,582,053 likewise uses a threaded anchor and a threaded spike with a washer as also does Melchiona, U.S. 2,895,235. Bernstein, U.S. 2,689,417 also shows a threaded anchor and threaded spike but differs in that it has a built-in washer on the spike cooperating with a detachable washer.

None of these patents which are representative of the prior art, provide the designated qualities of a replaceable spikenamely, firmness and rigidity; resistance to water seepage; and ease of replaceability.

One object of this invention is to provide a replaceable spike for shoes which remains firmly in place, resists the passage of water, and is readily replaceable.

Further objects and advantages of this invention will be apparent from specifications and claims which, taken together with the appended drawings wherein:

FIG. 1 is an exploded top view of one embodiment of this invention.

FIG. 2 is a corresponding side view of the exploded view of FIG. 1.

FIG. 9 shows a side view of embodiment of FIG. 8 in assembled form.

FIG. 10 is a vertical longitudinal section of FIG. 9.

The invention comprises generally a receiving chamber, an insert which fits inside the receiving chamber, a spike engageable with the insert and retaining means. The chamber has a rim which fits against the interior surface of the sole of the shoe and has a cylindrical Wall which extends through the sole. The portion of the receiving chamber which is on the inside surface of the sole is solid and has a central, downwardly directed protrusion. The insert fits into the receiving chamber and presses against the outer surface of the sole of the shoe. In assembling the unit on the sole, the receiving chamber is first placed in position by hammering or the like from the inner surface of the sole. Then the insert member is applied from the outer surface of the sole.

The invention comprises more specifically an anchor means having an integral solid rim adapted to engage the inner surface of a shoe sole and a tubular portion adapted to extend through the sole; a spike member; and an insert member having a tubular portion adapted to fit tightly inside the anchor tubular portion, an annular rim adapted to engage the outer surface of the shoe sole and means for engaging a spike member in a locked position.

In one form of this invention the insert tubular portion is provided with oppositely spaced longitudinal grooves and oppositely spaced recesses at the inner end. The spike member has top protrusions slidable in the grooves and engageable in the recesses. The spike member is inserted with the protrusions in the grooves and locked by twisting the protrusions into the recesses. An outer retaining member is provided to keep the spike member from rising and thus untwisting. FIGS. 1-6 show one form of this embodiment while FIG. 7 shows a different retaining means for a spike member.

Referring now to FIGS. 1-6, there is illustrated therein a receiving chamber 10, an insert element 20, a retaining ring 30, and a spike 40. Chamber 10 has a solid top wall 11 and depending tubular portion 12 having an inner surface 13. The top portion 11 is in effect a rim which is larger in diameter than the tubular portion 12 and is adapted to press against the interior surface of a shoe sole 60. The top portion 11 has a central downward protrusion 14.

The insert element 20 comprises a cylindrical rim 21 adapted to press against the exterior surface of a sole and a tubular portion 22 adapted to fit tightly inside tubular portion 12, against surface 13. Insert element 20 is provided with

recesses

24 and 25 for the seating of the

wings

41 and 42 of spike 40. It is also provided with

grooves

26 and 27 to permit passage of said wings before they are turned into locking position.

The spike 40 has in addition to its

upper wings

41 and 42, a lower tapered body portion 44, a median body portion, a groove 45 and an upper body portion 43.

The retaining ring 30 has a band 31 with enlarged

ends

32 and 33 and is made of resilient material. The ring 30 fits around the groove 45 having a wall 46 and with its enlarged

fiat end portions

32 and 33 prevents twisting of the spike. It should be noted that the retaining ring does not act as a support, the support being accomplished by the locking of the

wings

41 and 42 into the

recesses

24 and 25.

The entire assembly is essentially a press fit. Thus, the receiving cha-mtber 10 is driven into the sole from the interior until the solid rim 1 1 is tight against the sole. Then the insert element 20 is driven against the outer surface of the sole until its rim 21 is tight against the exterior surface of the sole and its tubular portion 22 is inserted into tubular portion 12 tightly. The spike is then inserted with the wings 4 1 and 42 guided in the

grooves

26 and 27 until the wings clear the end of the tube 23. The spike is then turned until the

wings

21 and 22 seat in the

grooves

24 and 25. Then the retaining ring 31 is slid onto groove 45..

Referring now to FIG. 7, there is illustrated therein a receiving chamber 110, an insert element 120, and a spike member 140. Chamber 111 has a solid top wall 111, and a depending tubular portion 112 having an inner surface 113. Top portion 111 has a central downward protrusion 114.

The insert element 120 has a cylindrical rim 121 adapted to fit tightly inside the tubular portion 112 against surface 113. It has recesses 12% and 125 for seating the wings i141 and 142 of the spike member 140. Grooves 12 6 and 127

permit wings

141 and 142 to pass up before they are turned into locking position into

recesses

24 and 125. In the spike member-illustrated in FIG. 7, the spike member 149 has

upper wings

141 and 14 2, lower tapered body portion 144, median body portion, and upper body portion 143. A hole 146 extends between opposite sides of 143 and is adapted to engage a cotter pin 148 to prevent rising and unlocking.

in FIGS. 8-10 the assembly comprises anchor 210, pressdit insert element 220 and spike 240. Anchor 210 has solid top Wall 211 and protrusion 214 and depending tubular portion 212 having an inner surface 213. Insert member 220 has a bottom wall 221 provided with a protrusion 222 having a tapered keyvvay 222a engagea ble with a registralble, slidable dovetail protrusion 24 3 having slot 244 for engaging locking means 245. The shoe sole is 260.

While several embodiments of this invention have been described in detail, it will be understood that it is not to be limited to the particular constructions described since various changes in form, proportions and arrangement of parts and in the details of construction may be resorted to Without departing from the spirit and scope of the invention or destroying any of the advantages contained in the same heretofore described and defined in the following claims.
