  • Patent number: 6435490
    Abstract: A dual hemisphere elastomer mount having a first hemisphere composed of an elastomer and having a polar region and a base region with the polar region of the first hemisphere having a circumference smaller than a circumference of the base region of the first hemisphere; and a second hemisphere composed of an elastomer having a polar region and a base region with the polar region of the second hemisphere having a circumference smaller than a circumference of the base region of the second hemisphere, the first hemisphere securely attached to the second hemisphere at the polar region of the first hemisphere and at the polar region of the second hemisphere creating a hour-glass shaped body whereby the elastomer mount can support a housing while attenuate shocks and vibrations.

  • Publication number: 20020110666
    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.

  • Publication number: 20020105125
    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.

  • Publication number: 20020105124
    Abstract: A shock isolator for a housing in an offset compressive axis with the shock isolator including either an elastomer triad or a hollow elastomer tetrahedron with each having support surfaces thereon that are laterally offset from each other to prevent direct axial compression with each of the shock isolators providing shock and vibration attenuation not normally obtainable in a direct axially compression condition.

  • Publication number: 20020105121
    Abstract: A shock isolator for use in a compressive mode comprising a pyramid-shaped elastomer having a cavity therein with the pyramid-shaped elastomer having a base supporting a set of triangular shaped sidewalls that each terminate in a apex with the triangular shaped sidewalls cantilevered from the base to jointly terminate at a pyramid-shaped apex to create a one-piece elastomer mount so that a force applied to the pyramid apex is transmitted to the base through an offset axis while shock and vibration forces are attenuated by the shear resistance of the shock isolator.

  • Publication number: 20020079632
    Abstract: A modular shock isolator and method of isolation of components of a system with multiple modular shock isolators arranged to provide different damping and vibration characteristics than an individual modular shock isolator. In one mode, a modular shock isolator having a base with legs extending from each side of the base with each of the legs having a foot that extends outward from the legs with the modular shock isolator either individually mounted to isolate a component or a plurality of modular shock isolators are be ganged, or stacked together to change the shock isolation characteristics of the shock mount formed from the multiple modular shock isolators. A layer of damping material can be sandwiched between layers of elastomers to dampen the natural spring-back of the materials.

  • Publication number: 20020079627
    Abstract: A molded or non-molded elastomeric shock cell having a base with legs extending from each side of the base with each of the legs having a foot that extends laterally outward from the legs to provide a unitary elastomeric shock cell that can be individually mounted to support plates or a plurality of elastomeric shock cells can be ganged, or stacked together to produce a composite isolator with different shock isolation characteristics. The elastomeric shock cell if mountable in one axis provide tension resistance and if mounted in a bias axis or right angle axis provide tension and compression resistance to shocks to the system.

  • Patent number: 6386134
    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.

  • Patent number: 6382603
    Abstract: A shock isolator comprising a first plate having a set of ridges and grooves extending there along and a second plate having a complementary set of ridges and grooves with an elastomeric sheet sandwiched between the two plates so that when a compressive force is applied to the two plates the elastomeric sheet resist the forces through compression resistance, tension resistance and shear resistance to provide both static support and shock isolation to an object supported by the shock isolator.
