COUNTERBALANCE FOR A PLATFORM BALANCE

摘要

A platform balance (10) includes a first frame support (12) and a second frame support (14) movable relative to the first frame support (12). At least one counter balance assembly (40) is provided to support the static weight of the first frame support (12) and elements connected thereto. The counterbalance assembly (40) includes a beam (42) and a pivot assembly (50) allowing the beam to pivot. A weight (44) is selectively positionable on the beam (42). A compliant assembly is supported by the beam (42) on a portion thereof on a side of the pivot assembly (50) opposite the weight (44). The compliant assembly supports the first frame support (12). The compliant assembly includes a second pivot assembly (58) and a planar motion assembly (60) coupled to the second pivot assembly (58).
