SHIPBOARD PLATFORM FOR PROTECTION OF OPERATOR FROM VIBRATIONS Russian patent published in 2010 - IPC F16F15/67 

FIELD: machine building.

SUBSTANCE: platform consists of rigid frame and vibration isolators joining frame with base. The support frame is made out of wood or composite material and is rigidly tied with the vibration isolators secured on a bulkhead. The bulkhead is connected with the support frame by means of damping elements of spring action. The vibration isolator consists of a spring, axis of which is perpendicular to the base, and of a lower and upper restrictors of spring run made out of elastomer. The spring interacts with the restrictors via a lower support cartridge and an upper cover enveloping the spring. The upper cover is rigidly connected with a threaded bushing coupled with the frame by means of a screw. The vibration damping element is positioned between the threaded bushing and the frame. The spring is located in the case rigidly joined with the base and connected to the cover. On end surface of the cover there is installed an arrester of frame run made out of elastomer.

EFFECT: upgraded efficiency of vibration isolation and simplified design.
