Abstract: A bulk modulus elastomeric element is employed in the present invention. The material from which the invention is fabricated is formed as a sheet, which has a plurality of channels that run through, or partially through it. The holes in the sheet are angled such that the remaining material may be of a parallelogram shape. The top and bottom surfaces of the particular element may be rectangular, circular, hexagonal, or other shapes, since the shape of the end surface is not important to the invention. An edge of an upper end surface is displaced from a remote edge of the lower surface so that a vertical line from one edge normal to the upper surface, is displaced from the remote edge of the lower surface, so that it preferably does not intersect any part of the lower surface when no forces are applied to the surfaces. However, in some instances, under load, a small overlap at the cross-sectional areas of the upper surface and lower surfaces, may be desirable.

Abstract: An elastomer isolator mount that can provide both compressive support and shear support to enable the elastomer isolator mount to attenuate shock and vibration forces to an object carried by the elastomer isolator mount with the ratio of compressive support to shear support controllable by the diameter of a plurality of angled holes in relation to width of a top support surface and the dynamic response characteristics of the elastomer isolator mount further controllable by selecting the shape of the sidewalls of the elastomer isolator mount. A plurality of elastomer isolator mounts can be further arranged in a group to provide a support platform for an object.

Abstract: A pallet type mount wherein a pair of rigid members each having extensions that spacedly mesh with each other and an elastomer member secured between the rigid members so that when a compressive force is applied to the rigid members the pallet type mount provides compressive force for a load thereon while absorbing shock and vibration energy through tension forces on the elastomer member.

Abstract: A stack of sheet elastomers, each having multiple holes therein, dissipates shock forces applied to it. The elastomeric sheets are formed with identical holes each of which have a periphery that is symmetrical around the centers of the holes that extend over a shock dissipation area of the device. The sheets are stacked so that one, or more continuous material passageways are formed through the stack that extend from one support surface to a parallel support surface. This allows for the elastomer material of these passageways to transmit sheer shock forces when a compressive force is applied normal to the support surfaces. Elastomeric, or other material of a composition different, preferably elastomeric, from the material of the stacked sheets, may be filled into holes of the sheets to adjust the characteristics of the device.
