Abstract

A clutch assembly for a lock includes a driver (1), having a driver shaft (9); a coupler (3); and a follower (2). The driver (1), the coupler (3) and the driver shaft (9) are configured to rotate concentrically together. The coupler (3) is configured to move along the central axis of the driver shaft (9) to couple to or decouple from the follower (2). The driver (1) and the follower (2) are configured to rotate concentrically together when the coupler (3) is engaged to the follower (2), and wherein the driver (1) and the follower (2) are configured to rotate independently when the coupler (3) is disengaged from the follower (2).
