SHOCK AND VIBRATION ISOLATION MOUNTING

摘要

Shock and vibration isolation mounting apparatus for releasably mounting a computer disk drive or the like to a chassis is described. Two pair of mounting assemblies are used; one of the pair is disposed below the drive with the elastomeric members thereof in compression and the other of the pair of mounting assemblies is disposed above the drive with the elastomeric members thereof in tension. Each of the mounting assemblies comprises a first elongated rigid channel member being U-shaped in cross section and comprising a base separating a pair of parallel spaced sides. The first channel member has a transverse member having a bore therethrough at one end perpendicular to both the base and the sides, and is adapted for attaching to the disk drive. The second elongated rigid channel member is also U-shaped in cross section and comprising a base separating a pair of parallel spaced sides. The second channel member which has a transverse member having a threaded bore therethrough at one end perpendicular to both the base and the sides, is sized to slidably fit within the first channel member. A spring-loaded captive bolt is carried by the transverse member of the first channel member for passing through the bore of the first channel member and threadedly engaging the threaded bore of the second channel member. First and second elastomeric members are carried by the second channel member on the base between the sides at opposite ends thereof. The elastomeric members each include a captive bolt perpendicular to the base thereof for attaching the second channel member to the adjacent surface. The ends of the first and second channel members opposite the transverse members include interactive ends adapted for drawing the ends together and for holding them tightly together as the captive bolt is used to pull the transverse members towards one another.
