Abstract
Abstract Vibration isolation apparatus in which the vibration-protected portion thereof is supported by the vibration-prone portion through the medium of a vertically-actuable multiaxis joint assembly that affords 3° of angular freedom. In one embodiment the joint assembly also affords 2° of translational freedom, and in another such translational freedom is introduced at the support for such assembly. Suitably controlled actuators between the two apparatus portions actively isolate a range of vibration frequencies in 6° of freedom. A spring support means for the protected portion offers passive isolation vertically.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
68 words
Load support apparatus comprising a vibration-prone mounting member and a load-bearing mounted member, a plurality of vertically-movable four-axis joint means carried by said mounting member and supporting said mounted member at horizontally spaced apart locations with freedom for relative movement between the two members in the vertical, longitudinal, lateral, roll, pitch, and yaw modes, and actuator means for effecting active vibration isolation in each of the aforesaid modes.
Claim 2
Dependent Claim
68 words
Load support apparatus comprising a vibration-prone mounting member and a load-bearing mounted member, a plurality of vertically-movable four-axis joint means carried by said mounting member and supporting said mounted member at horizontally spaced apart locations with freedom for relative movement between the two members in the vertical, longitudinal, lateral, roll, pitch, and yaw modes, and actuator means for effecting active vibration isolation in each of the aforesaid modes.
Claim 3
Dependent Claim
37 words
Load support apparatus as set forth in claim 1, wherein said plurality of vertically-movable four-axis joint means is in form of a plurality of bell-and-ring gimbal assemblies at three or more horizontally-spaced-apart locations on said mounted member.
Claim 4
Dependent Claim
88 words
Load support apparatus as set forth in claim 2, wherein each of said bell-and-ring gimbal assemblies is affiliated with a vertically movable support rod and comprises, a bell-shaped member having a small-diameter upper end and a large-diameter lower end, universal joint means interconnecting the upper end of said member to the upper end of said support rod, a ring gimbal having pivotal support by the lower end of said bell-shaped member, and pivotally supporting said mounted member along an axis perpendicular to that of the aforesaid pivotal support.
Claim 5
Dependent Claim
97 words
Load support apparatus comprising, a vibration-prone mounting member, a load-bearing mounted member, a vertically-movable support rod assembly, a biaxial joint means disposed on said support rod assembly and supporting said mounted member at its center of gravity with freedom for pitch, roll and yaw motions, ball-bearing-separated plate members supported by said mounting member and supporting said vertically-movable support rod assembly, said ball-bearing-separated plate members being interconnected by linkages to afford a degree of frictionfree motion between mounting and mounted members in lateral and longitudinal directions, and actuator means for effecting active vibration isolation of the aforesaid motions.
Claim 6
Dependent Claim
97 words
Load support apparatus comprising, a vibration-prone mounting member, a load-bearing mounted member, a vertically-movable support rod assembly, a biaxial joint means disposed on said support rod assembly and supporting said mounted member at its center of gravity with freedom for pitch, roll and yaw motions, ball-bearing-separated plate members supported by said mounting member and supporting said vertically-movable support rod assembly, said ball-bearing-separated plate members being interconnected by linkages to afford a degree of frictionfree motion between mounting and mounted members in lateral and longitudinal directions, and actuator means for effecting active vibration isolation of the aforesaid motions.
