Status-indicating cylindrical lock assembly

An apparatus, comprising:

• a chassis having a first chassis state and a second chassis state, the chassis comprising:
• a hub having a recess including a first channel, a second channel, and an intersection of the first channel and the second channel;
• a drive tube rotatably mounted to the hub;
• a slider movably seated in the second channel, the slider including a ramp, the slider having a non-actuated position in which the ramp is received in the intersection and faces the first channel, and an actuated position in which the ramp is retracted from the intersection;
• a movable element having an actuating position in the first chassis state and a deactuating position in the second chassis state;
• wherein, in the actuating position, the movable element is received in the intersection and is engaged with the slider;
• wherein, in the deactuating position, the movable element is retracted from the intersection and is disengaged from the slider;
• and
• wherein the movable element is structured to engage the ramp and urge the slider from the non-actuated position toward the actuated position as the movable element moves from the deactuating position toward the actuating position;
• and
• an escutcheon assembly comprising:
• a mounting plate coupled to the hub;
• a spring cage mounted on the mounting plate and longitudinally covering the slider;
• an escutcheon covering the mounting plate and the spring cage, the escutcheon including a window;
• an indicator plate movably mounted to the mounting plate, the indicator plate including a first indicium related to the first chassis state and a second indicium related to the second chassis state, wherein the indicator plate has a first position in which the first indicium is aligned with the window and a second position in which the second indicium is aligned with the window;
• and
• a linkage extending through the spring cage, the linkage having a first end connected with the slider and a second end connected with the indicator plate, wherein the linkage is structured to move the indicator plate from the second position to the first position in response to movement of the slider from the non-actuated position to the actuated position.

A cylindrical lockset, comprising:

• an outer chassis assembly, comprising:
• an outer hub;
• an outer spindle rotatably mounted to the outer hub;
• an outer drive tube mounted in the outer spindle, wherein the outer drive tube is rotatable about a longitudinal axis;
• a retractor slidably mounted in the chassis, wherein the retractor is structured to move along a lateral axis in response to rotation of the outer drive tube about the longitudinal axis;
• an inner chassis assembly, comprising:
• an inner hub;
• and
• an inner drive tube rotatably mounted to the inner hub, wherein the inner drive tube is rotatable about the longitudinal axis, and wherein the inner drive tube is structured to move the retractor along the lateral axis as the inner drive tube rotates about the longitudinal axis;
• a lock control assembly having a locking state in which the outer spindle is inoperable to rotate the outer drive tube and an unlocking state in which the outer spindle is operable to rotate the outer drive tube, the lock control assembly including plurality of movable elements, each of the movable elements having a locking position in the locking state and an unlocking position in the unlocking state;
• a slider associated with one of the movable elements, wherein the slider is movably seated in a guide channel formed in one of the outer hub and the inner hub, the slider having a lock-indicating position in response to the locking position of the associated movable element and an unlock-indicating position in response to the unlocking position of the associated movable element;
• and
• an escutcheon assembly mounted on the one of the outer hub and the inner hub, the escutcheon assembly comprising:
• an escutcheon having a window;
• an indicator plate movably mounted behind the window, the indicator plate having a lock-indicating state in which a locked indicium is visible through the window and an unlock-indicating state in which an unlocked indicium is visible through the window;
• and
• a linkage connecting the slider and the indicator plate, wherein the linkage is structured to move the indicator plate between the lock-indicating state and the unlock-indicating state in response to movement of the slider between the lock-indicating position and the unlock-indicating position.

An apparatus for a cylindrical lockset, the apparatus comprising:

• a hub having an inner recess including a longitudinal channel, a guide channel, and an intersection of the longitudinal channel and the guide channel;
• a plunger including an arm movably seated in the longitudinal channel, the plunger having an actuated plunger position in which the arm is received in the intersection and a non-actuated plunger position in which the arm is retracted from the intersection;
• a slider movably seated in the guide channel, the slider including a ramp, the slider having a non-actuated slider position in which the ramp is received in the intersection and faces the longitudinal channel, and an actuated slider position in which the ramp is retracted from the intersection, wherein the slider is structured to move between the non-actuated slider position and the actuated slider position in response to movement of the plunger between the non-actuated plunger position and the actuated plunger position;
• a mounting plate coupled to the hub;
• an escutcheon coupled to the mounting plate, the escutcheon including a window;
• an indicator plate movably mounted to the mounting plate, the indicator plate including an actuated indicium and a non-actuated indicium, the indicator plate having an actuated plate position in which the actuated indicium is aligned with the window and a non-actuated plate position in which the non-actuated indicium is aligned with the window;
• and
• a linkage having a first end coupled to the slider and a second end coupled to the indicator plate, wherein the linkage couples the slider with the indicator plate such that the actuated and non-actuated slider positions respectively correspond to the actuated and non-actuated indicator positions.
