Abstract:
1. A compressible spring for at least absorbing and dissipating energy from a dynamic impact load applied to said compressible spring, said compressible spring comprising: (a) a compressible elastomeric pad defining a central axis and having a pair of axial ends, said compressible elastomeric pad further having a pair of projections integrally formed therewith; (b) a pair of end members, each of said pair of end members having a surface thereof abuttingly engaging one of said pair of axial ends and an axial aperture formed through said each of said pair of end members concentric with said central axis; (c) a predetermined plurality of prongs formed integrally with each of said pair of end members, secured to said surface thereof, or a combination thereof, each of said predetermined plurality of prongs disposed on or offset from an outmost peripheral edge of said axial aperture and extending outwardly at a predetermined angle relative to said surface, wherein said material of said compressible elastomeric pad contacts opposing surfaces of said each of said predetermined plurality of prongs and wherein each of said pair of projections extends into a respective axial aperture and has a peripheral surface thereof sized for frictional engagement with an inner surface of said predetermined plurality of prongs.
