Abstract
An inside operator for a lock having a spring biased bolt includes a shaft which can be immobilized, thus preventing longitudinal bolt motion, by applying force in the axial direction to the handle of the operator. The operator shaft is telescopic to ensure that the coupling of the operator shaft to the bolt is not interrupted as the operator is switched between operational modes.
