Latch for Telescoping Structures
Abstract
Latch for three-member telescoping column developed for deployment of antenna 122 meters in diameter. Deployable column along axis of antenna open lattice structure with three longerons as principal loadbearing members. Column divided into telescoping sections that deploy, one section at time. Latch automatically locks sections into position during deployment and unlocks them when antenna restowed. Latch is four-bar linkage using over-center principle for locking, with Belleville spring washers to absorb deflections.
