Abstract
A vibration isolator apparatus for isolating a load from a floor and minimizing disturbances caused by rapid motions of the load components. The vibration isolator comprises a first isolator assembly that employs a parallelogram mechanism to isolate the load in a first direction while maintaining said load leveled and a second isolator assembly that provides passive isolation for the load in a second direction or directions. The second isolator assembly may include a pendulum assembly that is coupled to a dashpot. A homing means to bring and secure the load to an equilibrium home position during rapid movement of the load components and during interacting process between the load and other devices mounted on different platforms.
Claims15
A vibration isolator which isolates a load that is separated from a floor, comprising:
- a first isolator assembly that provides isolation of the load in a first direction, said first isolator assembly comprises a parallelogram mechanism which may include two parallel load bearing means and a linkage mechanism interconnecting said two load bearing means, each members of the parallelogram may pivot about the connecting joints;
- a second isolator assembly that is attached to said first isolator assembly and provides passive isolation of the load in a second direction;
- and
- a counter force generating means that maintains a separating gap between the two load bearing means when a force is applied to said load bearing means, the said counter force generating means comprises a spring system that is coupled to two members of the parallelogram mechanism.
