Translatory shock absorber for attitude sensors

A three-dimensional translatory shock absorber device for mounting a precision instrument or the like for reducing translatory vibrations or motion along each of the three axes defined by a cartesian-coordinate system comprising;

• a first L-shaped base member having a horizontal planar leg normal to the Z-axis direction and a shorter vertical planar leg normal to the X-axis direction;
• a second L-shaped member spaced above said first base member and having a horizontal planar leg and a shorter vertical planar leg is parallel alignment with said first L-shaped base member;
• a first translatory shock absorber device interposed between said vertical planar legs of said first L-shaped base member and said second L-shaped member for reducing translatory vibrations in the direction of the Z-axis;
• a cushioning spacer interposed between said horizontal planar legs of said first L-shaped base member and said second L-shaped member;
• a second translatory shock absorber device mounted upon the top surface of said horizontal planar leg of said second L-shaped member for reducing translatory vibrations in the direction of the X-axis;
• a third translatory shock absorber device mounted on the top plate of said second translatory shock absorber device for reducing translatory vibrations in the direction of the Y-axis;
• each of said translatory shock absorber devices comprising a first pair of spaced parallel plates and a second pair of spaced parallel plates interposed between said first pair of plates and being integral therewith;
• laterally extending grooves provided in said second pair of plates at the junctions between said first and second pair of plates;
• damping means interposed between said first pair of plates for limiting movement of said first pair of plates relative to each other;
• said precision instrument mounted on the top plate of said third translatory shock absorber device;
• whereby said grooves provide a flexible joint between said first and second pair of plates and whereby said combination of translatory shock absorber devices effectively isolates said precision instrument from translatory vibration along each axis of motion without introducing rotational effects through said shock absorber devices.
