The spike assembly includes a “ball and spring” mechanism for the purpose of said spike assembly from falling out of the receiver member. The receiver member can be a mounted part of the sole of the sole or heel of the shoe consists of 2 spherical radii on the internal wall wherein the ball seats in a extended position. The release tool is manually inserted for disengaging the spike assembly from the receiver member.
Description




FIELD OF THE INVENTION




Our invention relates to sport shoes, spikes or cleats extending downwardly from the sole. A replaceable spike system consisting of the sole of the shoe, a receiver member, and the spike assembly. The purpose of this invention is to provide the convenience of quick removal and replacement, while secure fixation of the spike or cleat, by using a “ball and spring” mechanism housed within the spike. A release tool or rounded rod, such as a nail, can be utilized to disengage the spike from the sole of the shoe, thereby unlocking is achieved. This invention can be used for any and all athletic footwear such as, climbing, track and field, football, baseball, soccer, and golf alike. In addition, this invention can benefit anyone in sports from adolescents to older age groups. This spike system has the capability of interchangeable spikes or cleats, from one design of a gripping element to another design depending upon the field or turf its used on.




BACKGROUND OF THE INVENTION




In the past, golfers wore metal or steel spikes since early 1900's, nevertheless, they became banned at many courses, in an effort to improve and maintain the greens. Recently, soft spikes were made of plastic material and they were made as an alternative to many problems associated with metal spikes or cleats. There are many different types of soft spikes and configurations used to affix or retain the spike to the sole of the shoe or the receiver member and have numerous drawbacks.




One example, as described in U.S. Pat. No. 5,638,615, Korsen, SHOE SPIKE APPARATUS, they claim a plurality of spring fingers affixed to the plate retains the spike member firmly and without lateral movement while providing for quick release and removal. This invention does provide for quick release and removal but, the spike can become unintentionally disengaged with wear.




Another example, as described in U.S. Pat. No. 5,768,809, Savoie, QUICK-RELEASE SPIKE FOR FOOTWEAR, they claim the spike encounters a quarter of a turn, respectively of 60 degrees, causing the tip of one of the extensions to slide over the edge of the spike opening, providing a locking mechanism. The disadvantage to this invention is a quarter of a turn in the opposite direction can cause the spike to disengage or dislodge and fall out.




Another example, as described in U.S. Pat. No. 4,633,600, Dassler et al, OUTER SOLE FOR AN ATHLETIC SHOE HAVING CLEATS WITH EXCHANGEABLE SNAP-ON GRIPPING ELEMENTS, they claim a snap-lock arrangement which is composed of an annular rib which engages annular groove thereby fastening is achieved. The disadvantage to this invention is that the annular rib from constant movement can displace the spike, and it would be complicated to manufacture. Finally, another example is U.S. Pat. No. 3,267,593, REPLACEABLE SPIKE FOR SHOES, Turner, they claim the spike is inserted into the receiver chamber until the wings clear. The spike is turned then the retaining ring is slid onto the groove. However, support is accomplished by locking of the wings.




All these examples, show many different ways for retaining spikes to a receiver member or the sole of the shoe such as, spring fingers, sliding over the shoulders, an annular rib, or locking of the wings, however, it would appear to be unintentionally complex for their use, can disengage easily by wear or quick movement of the shoe, and lack firmness and rigidity.




BRIEF SUMMARY OF THE INVENTION




It is an important objective with this invention to provide a structure not consisting of threads, spring fingers, clamps or a clamp-ring, washers, annular rings and the like. Our intentions with this invention is to hold the spike in place by using the “ball and spring” mechanism for easy insertion and removal without damage to the shoe sole. Moreover, to provide a construction of components made for recycling purposes, and provide a sturdy material, non-corrosive, durable, and provide a firm support while wearing. Another objective with this invention is to provide a structure for a shoe sole and spike that would be easy to assemble and manufacture and inexpensive to make and provide a better means of traction, gripping, and non-slipping to prevent accidents. Additional objectives and advantages over prior art will become more apparent, and understanding from the following description, taken in conjunction with the accompanying drawings forming a part of the specifications.
