VIBRATION INSULATED STAGE Russian patent published in 2006 - IPC F16F15/02 

FIELD: protection of operator against adverse effect of vibration.

SUBSTANCE: proposed vibration insulated stage for operator has rigid framework, plating which is used as bearing surface for operator and flexible members connecting the framework with base. Flexible members are connected with framework by means of articulated lever connecting framework with bearing unit of flexible member provided with pendulum suspension and compressive spring engageable with base and pendulum suspension. Pendulum suspension is made in form of threaded rod connected with spherical washer at one end and threaded bush which is also connected with spherical washer at one end which is connected with threaded rod. Spherical washers are engageable with at least three balls located on taper surface of bearing members which are engageable in their turn with upper end face of spring and with object to be vibration insulated; buffer limiting members made from elastomer are mounted in base.

EFFECT: enhanced efficiency of vibration insulation; simplified construction.
