Abstract
A shock isolator having a housing securable to a support structure with the housing containing a bell shaped elastomer having a base secured to the housing and an axially offset apex surface secured to a connector to cantileverly support equipment to be isolated from shock with the cantileverly support of apex surface from the base insuring that any displacement of the connector produces a substantial shearing action in the elastomer to effectively damp the effect of a shock on the shock isolator.
Claims17
A six degree of freedom shock isolator comprising:
- a housing, said housing securable to a support structure;
- an elastomeric material, said elastomeric material located within said housing, said elastomeric material having a general bell shape, said elastomeric material having an apex region with an internal apex support surface located therein and an annular base axially offset from said internal apex support surface, said annular base secured to said housing;
- and
- a connector, said connector located internally to said bell shape elastomeric material, said connector having a first end for supporting an object to be isolated from a shock, said connector having a second end, said second end secured to said internal apex support surface so that displacement of said connector in any direction produces a substantial shearing action in said elastomeric material to thereby dampen the shock to the connector.
The six degree of freedom shock isolator of claim 1 wherein the annular base is secured to an interior surface of said housing.
- 3.The six degree of freedom shock isolator of claim 2 wherein the annular base is adhesively secured to the interior surface of said housing.
A system for limiting shock transmission comprising:
- a ship, said ship having a support structure;
- a control cabinet;
- a six degree of freedom shock isolator, said six degree of freedom isolator having a housing, said housing cantileverly secured to said support structure;
- an elastomeric material positioned within said housing, said elastomeric having an apex support surface and an annular base axially offset from said apex support surface, said annular base secured to an interior surface of said housing over a 360 degree area;
- and
- a connector, said connector having a first end for supporting the control cabinet, said connector having a second end, said second end secured to said apex support surface over a 360 degree area to provide 360 degree cantilever support to said connector so that displacement of said support structure in any direction produces a substantial shearing action in said elastomeric material to thereby dampen a shock to the system.
A shock isolating system comprising:
- a housing, said housing cantileverly securable to a support structure;
- a one-piece elastomeric material, said one-piece elastomeric material positioned entirely within said housing when in an uncompressed state, said one-piece elastomeric material having a general bell shape with an enclosed apex region, said elastomeric material having an internal apex support surface and an annular base axially offset from said internal apex support surface, said annular base adhesively secured to said housing;
- and
- a connector, said connector having a first end for supporting an object to be isolated from a shock, said connector having a second end adhesively secured to said connector from said internal apex support surface so that displacement of said connector in any direction produces a substantial shearing action in said on-piece elastomeric material to thereby dampen the shock to the shock isolating system.
