| 摘要 | A molded shoe sole or heel having imbedded therein a receptacle with a threaded sleeve for receiving a threaded stem of a spike, such as a golf shoe spike, loggers boot spike, track shoe spike and the like, of the type having a laterally projecting flange which presses against a sealing ridge on the bottom surface of the shoe sole to thereby form with the spike a leaktight seal about the spike receptacle. | ||||||
| 权利要求 | 1. For a shoe, the combination of a resilient shoe bottom structure, said bottom structure including a bottom surface, at least one spike receptacle imbedded in said bottom structure, said spike receptacle including an internally threaded sleeve having an axis at substantially right angles to said bottom surface and an opening substantially flush with said bottom surface for receiving a threaded stem of a spike having a spike flange surrounding the stem, a raised annular resilient ridge extending from said bottom surface about and spaced a substantial distance from said bottom surface opening, said ridge including steep sides and a narrow crown forming a resilient engaging surface for a spike flange to provide at said resilient engaging surface with a spike flange a leaktight seal about said sleeve. 2. The combination as in claim 1 wherein said bottom structure is of flexural plastic composition. 3. The combination as in claim 2 wherein the flexural plastic composition is comprised of natural rubber. 4. The combination as in claim 2 wherein the flexural plastic composition is comprised of synthetic rubber. 5. The combination as in claim 2 wherein the flexural plastic composition is comprised of vinyl. 6. The combination as in claim 1 wherein said ridge has a cross-sectional shape which is tapered with a wider dimension at the bottom surface than at the engaging surface to facilitate conformance to contour changes at the engaging surface and provide resistance to lateral deflection at the bottom surface. 7. The combination as in claim 1 wherein said bottom structure is comprised of a separately molded sole and heel, a plurality of receptacles similar to said spike receptacle similarly imbedded in said sole and in said heel, and a ridge similar to said raised resilient ridge about each of said receptacles. 8. The combination as in claim 1 wherein said bottom structure is comprised of an integrally molded sole and heel, a plurality of receptacles similar to said spike receptacle similarly imbedded in said sole and in said heel, and a ridge similar to said raised resilient ridge about each of said receptacles. |
