Load Adapting Vibration Isolation Pallet Mechanisms
First Claim
1. An isolation system for a transportation pallet, comprising:
- a plunger assembly comprising a graduated surface area having a first end of the plunger assembly with a relatively smaller surface area than a second end having a relatively larger surface area; and
a cushion pad coupled to the plunger assembly such that when a load is applied to the plunger assembly, the plunger assembly is pressed into the cushion pad to cause the cushion pad to bear the load over a surface area of the plunger assembly corresponding to the magnitude of the load, and wherein as the load is increased a larger surface area of the plunger assembly and the cushion pad supports the load and as the load decreases, a smaller surface area of the plunger assembly and cushion pad supports the load.

Abstract
An isolation system for a transportation pallet, a transportation pallet, and a method of providing an isolation system are provided. The isolation system comprises a plunger assembly comprising a graduated surface area having a first end with a relatively smaller surface area than a second end having a relatively larger surface area. The isolation system further comprises a cushion pad coupled to the plunger assembly such that when a load is applied to the plunger assembly, the plunger assembly is pressed into the cushion pad to cause the cushion pad to bear the load over a surface area of the plunger assembly corresponding to the magnitude of the load. When the load is increased, a larger surface area of the plunger assembly and the cushion pad supports the load and as the load decreases, a smaller surface area of the plunger assembly and cushion pad supports the load

11. An isolation system for a transportation pallet, comprising:
-
a plunger assembly comprising a graduated surface area having a first end of the plunger assembly with a relatively smaller surface area than a second end having a relatively larger surface area; and a cushion pad coupled to the plunger assembly such that when a load is applied to the plunger assembly, the plunger assembly is pressed into the cushion pad to cause the cushion pad to bear the load over a surface area of the plunger assembly corresponding to the magnitude of the load, and wherein as the load is increased a larger surface area of the plunger assembly and the cushion pad supports the load and as the load decreases, a smaller surface area of the plunger assembly and cushion pad supports the load, wherein; the plunger assembly and cushion pad are coupled to one another by a metal bolt passing through the plunger assembly and cushion pad, and a metal nut at one end of the bolt preventing the plunger assembly and cushion pad from moving beyond the end of the bolt; the plunger assembly is a stack of metal washers of differing diameter, wherein the diameter of the washers in the stack increases with increased distance from the cushion pad; and the cushion pad is a pad comprising one or more layers of neoprene material.

14. A transportation pallet for transporting sensitive products, comprising:
-
a pallet comprising an upper deck and a lower deck; and an isolation system located between the upper deck and the lower deck of the pallet, wherein the isolation system comprises; a plunger assembly comprising a graduated surface area having a first end of the plunger assembly with a relatively smaller surface area than a second end having a relatively larger surface area; and a cushion pad coupled to the plunger assembly such that when a load of a product loaded onto the pallet is applied to the plunger assembly via the upper deck of the pallet, the plunger assembly is pressed into the cushion pad to cause the cushion pad to bear the load over a surface area of the plunger assembly corresponding to the magnitude of the load, and wherein as the load is increased a larger surface area of the plunger assembly and the cushion pad supports the load and as the load decreases, a smaller surface area of the plunger assembly and cushion pad supports the load. - View Dependent Claims (15, 16, 17, 18, 19)
