Abstract:
An elevator system comprising:an elevator car adapted to travel up and down within a hoistway;a guide rail extending along a length of said hoistway, and including a guide rail surface;a roller guide assembly affixed to said elevator car and slidably engaging said guide rail, said roller guide assembly including a roller, a roller guide base, a roller wheel arm, coupled in a freely rockable manner to said roller guide base and rockable in a lateral direction to said guide rail surface, and rotatably coupled to said roller, and means for urging said roller laterally against said guide rail surface; anda resin stop assembly coupled to said roller guide base and said roller wheel arm for selectively limiting lateral acceleration and velocity of said roller relative to said guide rail surface, in order to thereby reduce vibration of said elevator car, said resin stop assembly comprising a frustoconical rigid container coupled between said roller guide base and said roller wheel arm and a cylindrical resin spring having a volume encompassed by its outer surface substantially equal to the volume encompassed by the inner surface of said rigid container, said resin spring being deformable into said rigid container upon relative movement between said roller guide base and said roller wheel arm, said rigid container having a wider, open end for inserting said resin spring and a narrower, closed end.
