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.

A method of making a modular shock isolator comprising:
- forming a first sheet of elastomer material;
- spacedly securing a layer of damping material having a damping characteristic different from a damping characteristic of the first sheet of elastomer material to the first sheet of elastomer material with stitching;
- forming the first sheet of elastomer material into a base with laterally outward extending legs and laterally outward extending feet;
- securing the base to a rigid first member;
- and
- securing the feet to a second rigid member to form a modular shock isolator having a first set of shock and damping characteristics.
A method of making a modular shock isolator comprising:
- forming a first sheet of elastomer material;
- selectively securing a layer of damping material to the first sheet of elastomer material with an adhesive;
- forming the first sheet of elastomer material into a base with laterally outward extending legs and laterally outward extending feet;
- securing the base to a rigid first member;
- and
- securing the feet to a second rigid member to form a modular shock isolator having a first set of shock and damping characteristics.
A method of making a modular shock isolator comprising:
- forming a first sheet of elastomer material;
- sandwiching a layer of damping material between the first layer of elastomer material and a second layer of elastomer material;
- forming the first sheet of elastomer material into a base with laterally outward extending legs and laterally outward extending feet;
- securing the base to a rigid first member;
- and
- securing the feet to a second rigid member to form a modular shock isolator having a first set of shock and damping characteristics.
The method of system shock isolation comprising:
- forming a first modular shock isolator having a first set of shock and vibration characteristics;
- forming a second modular shock isolator having a second set of shock and vibration characteristics substantially the same as the first set of shock and vibration characteristics;
- determining a required shock and vibration characteristic of a plurality of components of a system to be protected from shock and vibration;
- and
- determining a set of different shock and vibration characteristics obtainable with use of the first and second modular shock isolators and then using a cooperative arrangement of the first and second modular shock isolators to isolate each of the plurality of components of the system from shock and vibration.
A modular shock isolator comprising:
- a first member;
- a second member
- a first sheet of elastomer material, said first sheet elastomer material having a base with a first leg extending from a first side of said base and a second leg extending from the second side of said base, said base secured to said first member, each of said legs having a laterally outward extending foot with each of said feet extending in opposite directions with each of said feet secured to said second member;
- a second sheet of elastomer material, said second sheet elastomer material having a base with a first leg extending from a first side of said base and a second leg extending from the second side of said base, said base secured to said first member, each of said legs of said second sheet having a laterally outward extending foot with each of said feet of said second sheet extending in opposite directions with each of said feet of said second sheet secured to said second member;
- and
- a third sheet of material having a damping characteristic different from a damping characteristic of said first sheet of elastomer material and said second sheet of elastomer material, said third sheet of material sandwiched between said first sheet of elastomer material and said second sheet of elastomer material.
