Abstract:
1. A dual-rate resilient isolator, comprising: a main body having a first engagement surface and an oppositely disposed second engagement surface; and a plurality of raised, generally conically shaped bumps disposed at said first engagement surface; wherein said main body is composed of a predetermined resilient material, and wherein said plurality of raised bumps is integrally formed with respect to the predetermined resilient material of said main body; wherein said main body has a perimeter; and wherein said plurality of raised bumps is arranged in a bump pattern at said first engagement surface, wherein said bump pattern comprises: wherein said outer ring comprises a plurality of outer ring bumps of said plurality of raised bumps which are circumferentially disposed such that, given an equally spaced disposition with respect to each other, circumferentially in sequence, after every second bump thereof, a bump is absent; wherein said inner ring comprises a plurality of inner ring bumps of said plurality of raised bumps which are circumferentially disposed such that, given an equally spaced disposition with respect to each other, circumferentially in sequence, after every second bump thereof, a bump is absent; and said medial ring comprises a plurality of medial ring bumps of said plurality of raised bumps which are circumferentially disposed such that, given an equally spaced disposition with respect to each other, circumferentially in sequence, after every second bump thereof, a bump is absent.
