Abstract: A door for mission critical enclosures, for example, cabinets containing sensitive items, such as electronics that may be exposed to high stress environments, for example shock and vibration. The door structure described provides improved mounting and lock features that can allow easy access while maintaining rigid structural needs and integrity. A door assembly for a cabinet generally includes a door that can be fitted directly, or indirectly, to an enclosure through an adapter frame. Generally, the door has fitting structures that operate as interlocking, tight fitting key sets. The fittings provide suitable detent features. An actuatable lock mechanism respectively locks and unlocks the door. The actuatable lock mechanism includes a ramped locking bolt that can engage a ramped surface of the cabinet or adapter frame to facilitate locking and unlocking of the door.

Abstract: A spring element is made of a spring material and is formed into a generally elliptical shape. Two mounting pins extend in a normal direction through parallel relatively short segments of said elliptically-shaped spring element. The mounting pins are substantially aligned with the shorter of the two axis of the elliptically-shaped spring element so as to extend both inwardly and outwardly of said elliptically-shaped spring element. An elastomeric coating is applied around substantially all of the spring elements and a pair of blocks, each of which surrounds one of the mounting pins receives one of the mounting pins. A number of spring elements are joined together by two parallel, spaced-apart coupling links which contain cavities therein to receive one of the blocks of each of the spring elements.
