Abstract:
1. In a handle set for a lock with a latch, the handle set being for a door that is between an interior handle and an exterior handle of the handle set, the door having a central plane, the improvement wherein: a coupling apparatus selectively couples the exterior handle to the latch, the coupling apparatus including an actuator and being activated by a non-contact signal from a transponder; and an authenticator circuit authenticates the signal from the transponder and controls the actuator; wherein the authenticator circuit and the actuator are positioned on an interior side of the central plane of the door and at least partially housed in the interior handle; wherein the coupling apparatus comprises a force transfer member, an outer coupling member and radially movable camming blocks, wherein the force transfer member and outer coupling member are coupled via the camming blocks in such a manner that a rotational movement of the force transfer member causes a rotational movement of the camming blocks; wherein said rotational movement of the force transfer member is not transferred through the camming blocks to the outer coupling member in a decoupled state and is transferred through the camming blocks to the outer coupling member in a coupled state; wherein a blocking element can be positioned between the camming blocks in the coupled state, the blocking element preventing the camming blocks from a radial giving way movement and thus coupling the force transfer member with the outer coupling member in the coupled state; and wherein the blocking element moves out of the way of the camming blocks in the decoupled state.
