Abstract
A shock-isolation structure for supporting a relatively light load on a supporting surface and having a plurality of spring units operable in both tension and compression oriented in a truss configuration with first ends of said spring units connected to the supporting surface for universal movement and with second ends of said spring units connected to the load for universal movement, with each of the spring units including a coil spring, an end cap, and a rod which extends outwardly through the end cap with a clearance fit in a nonextended position, a clevis body on the end of each of the rods, a groove in each of the end caps, and a ridge on each of the clevis bodies for mating engagement when the rod is in the nonextended position to thereby center each of the rods in each of the end caps.
Claims31
In a shock-isolation structure wherein a load is supported on a supporting surface with a plurality of spring units operable in both tension and compression therebetween and wherein said spring units are oriented in a truss configuration with first ends of said spring units connected to said supporting surface for universal movement and with second ends of said spring units connected to said load for universal movement, the improvement wherein said plurality of said spring units each includes a sleeve, a coil spring in said sleeve, an end cap on said sleeve, a rod which extends outwardly through said end cap with a clearance fit in a nonextended position, a body on the end of said rod, and a depression and protrusion relationship between said end cap and said body for mating engagement therebetween when said rod is in said nonextended position to thereby center said rod in said end cap with said clearance therebetween, said protrusion being a ridge, and said depression being a groove which mates with said protrusion.
