Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
159 words
A vibration and/or noise isolating device comprising a helical spring provided at one (generally upper) end with means for engaging or receiving a member to be supported in a substantially vibration/noise isolated manner, the spring being mounted at its other (generally lower) end by way of an elastomeric expanding insert which engages at least part of an endmost convolution of the spring generally radially from the interior of the spring, the elastomeric insert being expanded into retaining engagement with the spring by means of a metal or plastics expanding member disposed concentrically with the expanding insert and shaped at its periphery in such a manner as to impart an expanding force to the insert when moved axially towards the support platform on tightening of an assembly screw which is in screw-threaded engagement with a bore of the expanding member, the assembly screw extending into the expanding member from the side of the mounting member remote from said endmost convolution.
Claim 2
Dependent Claim
159 words
A vibration and/or noise isolating device comprising a helical spring provided at one (generally upper) end with means for engaging or receiving a member to be supported in a substantially vibration/noise isolated manner, the spring being mounted at its other (generally lower) end by way of an elastomeric expanding insert which engages at least part of an endmost convolution of the spring generally radially from the interior of the spring, the elastomeric insert being expanded into retaining engagement with the spring by means of a metal or plastics expanding member disposed concentrically with the expanding insert and shaped at its periphery in such a manner as to impart an expanding force to the insert when moved axially towards the support platform on tightening of an assembly screw which is in screw-threaded engagement with a bore of the expanding member, the assembly screw extending into the expanding member from the side of the mounting member remote from said endmost convolution.
Claim 3
Dependent Claim
20 words
An isolating device as claimed in claim 1, wherein the bore is at the axial centre of the expanding member.
Claim 4
Dependent Claim
20 words
An isolating device as claimed in claim 1, wherein the expanding member is engaged by a plurality of assembly screws.
Claim 5
Dependent Claim
66 words
An isolating device as claimed in claim 1, wherein the spring is provided at its other end with means for receiving or engaging the equipment to be supported, said means being attached to the other end of the spring by an assembly of an assembly screw, elastomeric expanding insert, and expanding member, of the same general construction as used at the lower end of the spring.
Claim 6
Dependent Claim
52 words
An isolating device as claimed in claim 4, wherein at the equipment supporting end of the spring, the assembly screw is of larger diameter than the assembly screw used at the lower end of the spring, and internally threaded so as to provide means for fixing thereto the equipment to be supported.
Claim 7
Dependent Claim
86 words
An isolating device as claimed in claim 1, wherein a plurality of said elastomeric expanding inserts are provided by which the spring is mounted at its said other end, the expanding inserts each engaging a part of said endmost convolution, the inserts of the said plurality being angularly spaced around the said endmost convolution so as to provide support for the said convolution at a corresponding plurality of regions, each of said elastomeric inserts being expanded by means of a corresponding metal or plastics expanding member.
