Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
149 words
A shock absorbing assembly comprising a core member having a sidewall extending longitudinally between proximal and distal ends and being molded of a low density elastomeric material, fastening means for mounting the assembly such as a stud bolt, nut or the like inserted before molding and embedded in the proximal end of said core member, said core member being formed with a plurality of longitudinally spaced annular anchoring grooves extending substantially inwardly and positioned on said sidewall between the proximal and distal ends, and a cover member molded of a high density elastomeric material enclosing therein said core member inserted before molding said cover member, the inner surfaces of said cover member overlying the sidewall of the core being formed with a plurality of similarly longitudinally spaced ridges engaging the anchoring grooves of said core member, said ridges extending substantially inwardly sufficient to restrain deformation of said core member.
