Vibration isolator with low elevation seismic restraint

摘要

A vibration isolator with low elevation seismic restraint comprises a support member, at least two vibration isolating members, a top plate, a seismic snubber and a snubber limit plate. The vibration isolating members, are seated on the support member opposing end portions. The top plate has a middle portion and opposing end portions, wherein the top plate spans over the vibration isolating members, such that the vibration isolating members are between the support member and the top plate. The seismic snubber has a shaft element that is mounted to the top plate on one end. A snubbing limit plate is mounted to the support member such that it spans the U shaped support member middle portion, wherein the shaft member second end is between the snubbing limit plate, and the support member. The shaft member passes through the support member via a through-hole, and a first snubber element mounted to the shaft element second end, such that seismic movement is limited by the snubbing limit plate and the support plate.

1. A vibration isolator with low elevation seismic restraint for mounting equipment to a mounting surface, comprising:
support member having a middle portion and opposing end portions, wherein said middle portion is U shaped; at least two vibration isolating members, each having a first end, and a second end, wherein said vibration isolating members second ends are seated on said support member opposing end portions, a top plate having a middle portion and opposing end portions, wherein said top plate spans over said vibration isolating members, such that said vibration isolating members are between said support member and said top plate, and wherein said vibration isolating members first ends are mounted to said top plate end portions, wherein said support member is situated such that said U shaped middle portion brings said support member closer to said top plate than said support member opposing end portions, a seismic snubber having a shaft element having a first end and a second end, wherein said seismic snubber shaft element first end is mounted to said top plate and further comprising a snubbing limit plate which is mounted such that it spans the U shaped support member middle portion, wherein said seismic snubber shaft element second end is between said snubbing limit plate, and said support member, wherein said shaft member passes through said support member via a through-hole, and a first snubber element mounted to said shaft element second end, such that seismic movement is limited by said snubbing limit plate and said support member.
