Abstract
A handle set including a chassis and a handle mounted on the chassis. The handle includes a shank having a load bearing section, a primary actuating section, and a secondary actuating section. The chassis includes a housing, a support spindle, a primary actuator, and a secondary actuator. The support spindle is longitudinally coupled with the load bearing section, and the primary actuator is rotationally coupled with the primary actuating section of the handle. The handle set has a first configuration in which the secondary actuating section is engaged with the secondary actuator, and a second configuration in which the secondary actuating section is disengaged from the secondary actuator.

-17. (canceled)
A handle, comprising:
- a manually graspable portion extending laterally outward from a longitudinal rotational axis of the handle;
- a proximal section positioned adjacent the manually graspable portion, wherein the proximal section is configured for rotational coupling with a primary actuator of a lockset and includes a proximal opening structured to receive a portion of a primary actuator of the lockset, wherein the proximal opening has a proximal opening longitudinal cross-section, and wherein the proximal opening longitudinal cross-section is non-circular;
- a distal section including a distal opening having a distal opening longitudinal cross-section, wherein the distal section comprises one of an active section and an idle section;
- wherein the active section is configured for rotational coupling with a secondary actuator of the lockset, wherein distal opening longitudinal cross-section of the active section is non-circular and includes at least one recess;
- wherein the idle section is not operable to be rotationally coupled with the secondary actuator and includes a collar operable to surround at least a portion of the secondary actuator;
- and
- an intermediate section positioned between the proximal section and the distal section, wherein the intermediate section is configured for rotational coupling with a support spindle of the lockset and includes an intermediate opening structured to receive a portion of the support spindle, an aperture in communication with the intermediate opening, and a coupling member received in the aperture, wherein the intermediate opening has an intermediate opening longitudinal cross-section, and wherein the coupling member is operable to engage the support spindle to rotationally couple the handle with the support spindle.

A system, comprising:
- a plurality of handles including a first handle and a second handle, each handle comprising a grasp portion, a proximal section positioned adjacent the grasp portion, a distal section, and an intermediate section positioned between the proximal section and the distal section;
- wherein the proximal section of each handle is configured for rotational coupling with a primary actuator of a lockset;
- wherein the intermediate section of each handle is configured for engagement with a support spindle of the lockset;
- wherein the distal section of the first handle comprises an active section configured for rotational coupling with a secondary actuator of the lockset;
- and
- wherein the distal section of the second handle comprises an idle section that is not operable to be rotationally coupled with the secondary actuator.
3 more elements
A method, comprising:
- selecting one of a first handle or a second handle, wherein each of the first handle and the second handle comprises a grasp portion, a proximal section positioned adjacent the grasp portion, a distal section, and an intermediate section positioned between the proximal section and the distal section, wherein the distal section of the first handle comprises an active section, and wherein the distal section of the first handle comprises an idle section;
- installing the selected handle to a lockset comprising a primary actuator, a support spindle, and a secondary actuator, wherein installing the selected handle comprises:
- rotationally coupling the proximal section with the primary actuator;
- and
- engaging the intermediate section with the support spindle;
- wherein, when the selected handle is the first handle, installing the selected handle further comprises rotationally coupling the active section with the secondary actuator;
- and
- wherein, when the selected handle is the second handle, installing the selected handle further comprises maintaining the idle section rotationally decoupled from the secondary actuator.
