Abstract

Shock and vibration isolation mounting apparatus for releasably mounting a computer disk drive, or the like. Two pair of mounting assemblies are used for attaching to the drive and to respective ones of opposed surfaces between which the drive is disposed. One of the pair of mounting assemblies 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. The first channel member is adapted for attaching to the disk drive. There is a second elongated rigid channel member also being U-shaped in cross section and comprising a base separating a pair of parallel spaced sides. The second channel member has a transverse member having a threaded bore therethrough at one end perpendicular to both the base and the sides. The second channel member 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 to pull the transverse members towards one another. 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 comprising the ends of the sides of the first channel member angling at about 45° back towards the base and the ends of the sides of the second channel member including outward facing tabs angling at about 45° back towards the base so as to wedgedly force the bases of the first and second channel members tightly towards one another.
