in a shear condition rather than a compression condition and a force on the second end support is cantileverly supported to place the elastomer in a shear condition rather than a compression condition elastomer mounts 21 22 are preferably of the type shown in my copending patent application ser no 09 779 423 filed feb 28 2001 titled double triad elastomer mount which is hereby incorporated by reference the application discloses an elastomer shock isolator that is positioned in the shear or tension mode as opposed to an axial compression mode such elastomeric isolators provide enhanced shock and vibration attenuating characteristics in response to dynamic forces due to shock and vibration fig5 is a perspective view of the double triad one piece shock isolator 30 disclosed in the ser no 09 779 423 for providing shock and vibration attenuation while providing axially offset support to an object isolator 30 is a one piece two tetrahedron elastomer shock isolator 30 that simultaneously isolates shocks and supports a static load shock isolator 30 has a set of integral elastomer side walls forming a first tetrahedron elastomer shell 31 with a tetrahedron shaped cavity 31 c therein and a second tetrahedron elastomer shell 32 having a set of integral elastomer side walls forming a second tetrahedron elastomer shell with a tetrahedron shaped cavity 32 c therein a central axis 33 is shown extending through an apex end 32 a of elastomer shell 32 and an apex end 31 a of elastomer shell 31 fig2 shows apex end 31 a and apex end 32 a are smoothly joined to each other at junction surface 39 to form the one piece two tetrahedron elastomer shock isolator.
