Abstract
An exemplary access control device generally includes a mounting location, a first selected feature, a lock actuator mounted in the mounting location, and a spacer. The spacer includes a second attachment feature and a ledge. The second attachment feature is releasably coupled with the first attachment feature, and the ledge restricts movement of the lock actuator.
Claims19
A handleset, comprising:
- a housing;
- a spindle rotatably mounted to the housing for rotation about a longitudinal axis, the spindle comprising an aperture;
- a lock actuator mounted in the spindle;
- a handle mounted to the spindle;
- and
- a spacer removably coupled to the spindle, the spacer comprising:
- a protrusion releasably engaged with the aperture via a frictional interference fit;
- and
- a ledge restricting movement of the lock actuator;
- and
- wherein the protrusion is configured to exit the aperture in response to movement of the spacer in a direction transverse to the longitudinal axis.
8 more elements
An access control device, comprising:
- a mounting location;
- a first attachment feature;
- a lock actuator mounted in the mounting location, the lock actuator comprising a shell and a plug mounted in the shell for rotation about a longitudinal axis;
- and
- a spacer, comprising:
- a second attachment feature releasably coupled with the first attachment feature, thereby preventing longitudinal movement of the spacer relative to the first attachment feature;
- and
- a ledge restricting longitudinal movement of the lock actuator;
- and
- wherein the second attachment feature is configured to disengage from the first attachment feature in response to movement of the spacer in a direction transverse to the longitudinal axis.
7 more elements
A kit, comprising:
- an access control device comprising an attachment feature and a mounting location operable to receive each of a first lock actuator and a second lock actuator, wherein each of the first lock actuator and the second lock actuator comprises a corresponding and respective shell and a corresponding and respective plug mounted in the shell for rotation about a longitudinal axis, wherein each shell comprises a corresponding and respective tower having a corresponding and respective tower length, and wherein the tower length of the first lock actuator is greater than the tower length of the second lock actuator;
- a first spacer comprising a first spacer attachment feature operable to engage the attachment feature as a result of movement of the first spacer relative to the attachment feature in a direction transverse to the longitudinal axis, and a first ledge offset from the first spacer attachment feature by a first offset distance;
- a second spacer comprising a second spacer attachment feature operable to engage the attachment feature as a result of movement of the second spacer relative to the attachment feature in the direction transverse to the longitudinal axis, and a second ledge offset from the second spacer attachment feature by a second offset distance greater than the first offset distance;
- wherein, with the attachment feature engaged with the first spacer attachment feature, the first ledge is operable to engage the tower of the first lock actuator to thereby restrict movement of the first lock actuator;
- and
- wherein, with the attachment feature engaged with the second spacer attachment feature, the second ledge is operable to engage the tower of the second lock actuator to thereby restrict movement of the second lock actuator.
