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. ## Claims ### Claim 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 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 shaft member 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 plate. ### Claim 2 (depends on 1) The vibration isolator of claim 1 wherein said vibration isolating members are springs. ### Claim 3 (depends on 2) The vibration isolator of claim 2 further comprising spring cups, wherein said springs are seated on said support member in said spring cups to ensure that they maintain position. ### Claim 4 (depends on 1) The vibration isolator of claim 1 wherein said first snubber element is neoprene. ### Claim 5 (depends on 1) The vibration isolator of claim 1 wherein said shaft element first end is removeably mounted to said top plate via a mounting mechanism. ### Claim 6 (depends on 1) The vibration isolator of claim 1 wherein said shaft element first end is integrally mounted to said top plate. ### Claim 7 (depends on 1) The vibration isolator of claim 1 further comprising a second snubber element which would be separated from said first snubber element by a snubber middle plate. ### Claim 8 (depends on 7) The vibration isolator of claim 7 wherein said first and second snubber elements are mounted to said snubber via said snubber shaft element. ### Claim 9 (depends on 8) The vibration isolator of claim 8 wherein said first and second snubber elements are mounted to said snubber shaft element by a screw which is threaded into the snubber shaft element second end. ### Claim 10 (depends on 9) The vibration isolator of claim 9 wherein washers are fitted to the screw to ensure the attachment of the snubber elements. ### Claim 11 (depends on 7) The vibration isolator of claim 7 wherein said second snubber element is neoprene. ### Claim 12 (depends on 1) The vibration isolator of claim 1 further comprising a lateral snubbing element. ### Claim 13 (depends on 1) The vibration isolator of claim 1 further comprising a lateral snubbing element wherein said lateral snubbing element slides over said snubber shaft element, and wherein said support plate through hole is of sufficient size to allow said lateral snubbing element to pass through with a clearance. ### Claim 14 (depends on 1) The vibration isolator of claim 1 wherein said first snubber element is mounted to said snubber second end with a mounting mechanism, wherein said snubber limit plate has an access hole and wherein said mounting mechanism passes through said access hole, and into said snubber shaft element second end, wherein said first snubber element is large enough such that it will not pass through said access hole. ### Claim 15 (depends on 9) The vibration isolator of claim 9, wherein said snubber limit plate has an access hole and wherein said screw passes through said access hole, and into said snubber shaft element second end, and wherein said first and second snubber elements are large enough such that they will not pass through said access hole ### Claim 16 (depends on 12) The vibration isolator of claim 12 wherein said lateral snubbing element is neoprene. ### Claim 17 (depends on 13) The vibration isolator of claim 13 wherein said snubber limit plate has an access hole of sufficient size such size to allow said lateral snubbing element to pass through. ### Claim 18 (depends on 1) The vibration isolator of claim 1 further comprising adjustment screws for said vibration isolating members, wherein said screws extend through said top plate such that the vibration isolating members can be adjusted after installation of the unit. ### Claim 19 (depends on 1) The vibration isolator of claim 1 further comprising adjustment screws for said vibration isolating members, wherein said screws extend through said support member such that the vibration isolating members can be adjusted after installation of the unit.
