Abstract
A universal mounting base for protecting fragile equipment against shock vibration. A resilient plastic foam pad of rectangular outline is divided into quadrature air cavities and sandwiched between bottom and top plates. The top plate includes four matrices of holes, each matrix registering with a respective cavity, and being selectively blocked by cover pads interfaced between the top plate and the bottom of the equipment to be supported. Holes selected for blocking are empirically determined for a given weight and center of gravity of the equipment to achieve maximum dynamic stability and protection.
Claims9
A universal shock and vibration mount comprising:
- a lower plate;
- an upper plate having a plurality of openings therethrough;
- a resilient member disposed between the upper plate and the lower plate and having a cavity therein communicating with said plurality of openings;
- and
- cover means superimposed upon a predetermined number of said plurality of openings for occluding the predetermined number of openings.
A universal shock and vibration mount comprising:
- a lower plate;
- an upper plate having a plurality of holes therethrough, wherein said holes are arranged in a plurality of distinct hole groups;
- a resilient member disposed between the upper plate and the lower plate and having a plurality of cavities therein, wherein each cavity communicates with a respective one of said hole groups;
- and
- a plurality of cover means wherein each said cover means is superimposed upon a respective one of said hole groups for occluding a predetermined number of holes within a respective hole group.
A universal shock and vibration mount for an object having at least one surface comprising:
- a lower plate;
- an upper plate formed to receive said surface and having a plurality of holes therethrough wherein said holes are arranged in a plurality of distinct hole groups;
- a resilient member disposed between the upper plate and the lower plate and having a plurality of cavities therein, wherein each cavity communicates with a respective one of said hole groups;
- and
- a plurality of cover means each of which is associated with a respective one of said hole groups and each of which occludes a predetermined number of holes within a respective hole group wherein each of said cover means is secured to a predetermined portion of said surface adjacent a corresponding hole group.
A universal shock and vibration mount for a mass comprising:
- a lower plate;
- an upper plate formed to accept the mass and having a plurality of openings therethrough disposed in matrices;
- resilient means operatively secured between said lower plate and said upper plate and including a plurality of cavities therein, each cavity communicating with a respective one of said matrices;
- cover means adapted to be secured to the mass at the interface with said upper plate for blocking selected ones of said openings in each of said matrices;
- wherein said upper plate further includes a flat surface having a plurality of edges and a vertical rim around all edges excepting one edge, a pair of structures connected to the bottom of said flat surface adjacent opposite ends of said one edge, a pair of elongated rods each pivotably connected to a respective structure in a vertical plane, and a pair of fasteners each connected to a respective rod for engaging the mass.
