Shock mounting structure and magnetic disk apparatus

Abstract

A device that is to be isolated from mechanical shock and vibration such as a magnetic disk storage device is provided with a series of four shock mounting members that have a bolt projecting from one axial end and a stiffened grooved portion at the opposite axial end. A frame member with a rigid end portion and cantilevered, resilient frame members extending therefrom carries a series of U-shaped hook portions that are aligned with the shock mounting members. The pair of hooks on the end portion face the same direction and extend in the opposite direction with respect to the cantilevered frame portions. The other pair of hooks are mounted on the resilient cantilevered frame portions and face toward or away from one another so that they may be placed in engagement with the cooperating shock mounting member grooves by forcing the cantilevered frame portions toward or away from one another and thereafter releasing such parts when the hooks are aligned with the respective grooves. Thereafter accidental disengagement of the hooks is prevented by disabling the cantilevered frame portions by attachment of the frame to another rigid member of the assembly such as a circuit card.
