Abstract

A vibration isolation platform having supports such as air pistons to damp out low frequency vibrations is equipped with a means for restricting pitch and roll motion as the weight distribution is changed and the vibration isolation platform exhibits vertical motion. The preferred means for restricting are torsion bars and tension means which transfer force from one part of the platform to the other.

Claims

1. An apparatus, comprising:

a) a vibration isolation platform for supporting objects, wherein the vibration isolation platform is supported against gravity by at least one vibration damping support member, wherein the at least one vibration damping support member allows vertical motion of the vibration isolation platform as objects are removed and added to the vibration isolation platform; and

b) means for restricting rotational motion of the vibration isolation platform as the distribution of weight on the vibration isolation platform is changed and the vibration isolation platform exhibits vertical motion.

2. The apparatus of claim 1, wherein the means for restricting is at least one torsion bar.

3. The apparatus of claim 1, wherein the means for restricting are tension elements.

4. An apparatus, comprising:

a) a vibration isolation platform for holding objects;

b) a plurality of tension members attached in tensile attachment to the vibration isolation platform at a plurality of points;

c) at least one supporting member supporting the vibration isolation platform against gravity and against tension produced by the tension members;

d) a tension producing device attached in tensile attachment to each of the plurality of tension members, wherein each of the plurality of tension members is attached in tensile attachment to the same attachment point of the tension producing device.

5. The apparatus of claim 4, wherein the tension producing device is a spring.

6. The apparatus of claim 5, wherein the spring is attached to a base, the base supporting the at least one supporting member.

7. The apparatus of claim 6, wherein the spring is attached to the base through a damping element.

8. The apparatus of claim 4, wherein the at tension producing device is a pressurized tension producing member attached to a base, the base supporting the at least one supporting member.

9. The apparatus of claim 8, wherein the pressurized tension member is attached to the base through a damping element.

10. The apparatus of claim 4, wherein the tension producing device is an elastomeric element attached to a base, the base supporting the at least one supporting member.

11. The apparatus of claim 4, wherein the elastomeric element is attached to the base through a damping element.

12. The apparatus of claim 4, wherein the tension producing device is a weight.

13. The apparatus of claim 4, wherein the at least one supporting member is a pressurized support member.

15. The apparatus of claim 4, wherein the at least one supporting member is an elastomeric element.

14. The apparatus of claim 14, wherein pressure in the at least one supporting member is automatically changed to return the vibration isolation platform to a starting position after a weight is added to the vibration isolation platform.

16. An apparatus, comprising:

a) a vibration isolation platform for holding objects;

b) a plurality of tension members attached in tensile attachment to the vibration isolation platform at a plurality of points;

c) at least one supporting member supporting the vibration isolation platform against gravity and against tensile forces produced by the plurality of tension members, the at least one supporting member supporting the vibration isolation platform with compressive fluid forces;

d) a tension producing device attached in tensile attachment to each of the plurality of tension members, wherein the tension in the main tension member is the sum of the tension forces of the plurality of tension members.
