Abstract: A telescopic position adjustment mechanism allows for a telescoping element to be indexed by fixed increments toward a more telescopically collapsed position, relative to its base. The telescopic position adjustment mechanism uses a stepping reservoir that can, in a stepping configuration, selectively receive a predetermined volume of fluid from a support reservoir that supports the telescoping element against the base, enabling the telescoping element to collapse toward the base by a distance corresponding to the predetermined volume of fluid. In a locking configuration, the volume of fluid in the support reservoir is constant and the telescopic position is fixed, and in a free movement configuration fluid can flow freely between the support reservoir and a sink reservoir to permit free telescopic movement. A rotation resistance mechanism uses a locking key that is biased into engagement with a locking channel to inhibit rotation of the telescoping element relative to the base.

Abstract: Unbonded fiber reinforced elastomeric isolators (FREIs) have desirable characteristics for seismic isolation, but the unbonded application also introduces several design limitations in comparison to bonded elastomeric isolators. Unbonded FREIs are not capable of resisting tensile forces, making this type of isolator inappropriate for situation where overturning is of concern or regions where large vertical accelerations are anticipated. Furthermore, since unbonded FREIs rely on friction to transfer horizontal forces, permanent slip could occur. Concerns over both transfer of tensile forces and permanent displacement can be obviated by partially bonding the FREI to the supports. In this way, partially bonded FREIs (PB-FREIs) retain the beneficial characteristics of an unbonded FREI, but also demonstrate characteristics of a bonded isolator, notably tensile forces can be transferred and potential permanent displacement is inhibited.
