Abstract

A status indicating handle assembly generally includes a handle, an activation carrier mounted in the handle, and a status indicator mounted in the handle and engaged with the activation carrier. The handle includes a shank extending along a longitudinal axis and a grip portion extending laterally from the shank. The activation carrier is mounted in the shank, and has an unlocking position and a locking position. The status indicator has a first state in which a first indicium is displayed and a second state in which the first indicium is not displayed. The activation carrier transitions the status indicator between the first state and the second state as the activation carrier moves between the locking position and the unlocking position.

First claim

What is claimed is:

1. A lockset, comprising:
a lock chassis having a locked state and an unlocked state;
a latchbolt connected with the lock chassis;
a handle connected with the lock chassis such that when the lock chassis is in the unlocked state, rotation of the handle causes retraction of the latchbolt, and wherein the handle includes a shank and a grip portion extending from the shank, the grip portion defining a chamber including an opening extending along a length direction of the grip portion; and
a status indicator movably mounted in the chamber and movable between a first position in which the status indicator displays a first indicium and a second position in which the status indicator does not display the first indicium; and
wherein movement of the lock chassis between the locked state and the unlocked state transitions the status indicator between the first position and the second position, thereby indicating a current locked/unlocked state of the lock chassis.

2. The lockset of claim 1 , further comprising an activation carrier mounted in the shank of the handle and connected with the chassis, the activation carrier having a locking position corresponding to the locked state and an unlocking position corresponding to the unlocked state; and
wherein the activation carrier moves the status indicator between the first position and the second position as the activation carrier moves between the locking position and the unlocking position.

3. The lockset of claim 2 , wherein the status indicator comprises a rotatable barrel including:
a first section comprising the first indicium; and
a second section comprising a second indicium different from the first indicium;
wherein the first section is visible through the opening when the lock chassis is in one of the locked state or the unlocked state; and
wherein the second section is visible via the opening when the lock chassis is in the other of the locked state or the unlocked state.

4. The lockset of claim 3 , further comprising a first magnet mounted to the activation carrier and a second magnet mounted to the barrel; and
wherein magnetic interaction between the first magnet and the second magnet drives the barrel to rotate between a first position and a second position in response to movement of the activation carrier between the locking position and the unlocking position.

5. The lockset of claim 1 , wherein the shank extends along a longitudinal axis and the grip portion extends along a lateral axis arranged transverse to the longitudinal axis; and
wherein the status indicator comprises a barrel mounted in the chamber for rotation about the lateral axis; and
wherein the barrel includes a first section comprising the first indicium and a second section comprising a second indicium different from the first indicium.

6. The lockset of claim 5 , further comprising:
a first magnet operably coupled with the lock chassis such that the first magnet moves between a locking position and an unlocking position as the chassis moves between the locked state and the unlocked state; and
a second magnet mounted to the barrel;
wherein magnetic interaction between the first magnet and the second magnet drives the barrel to rotate between a first position in which the first indicium is displayed and a second position in which the second indicium is displayed as the lock chassis moves between the locked state and the unlocked state.

7. The lockset of claim 1 , wherein when the lock chassis is in the locked state, the handle is not operable to cause retraction of the latchbolt.

8. A status indicating handle assembly, comprising:
a lever handle including a shank extending along a longitudinal axis and a grip portion extending in a lateral direction from the shank, the grip portion comprising a chamber extending primarily in the lateral direction;
a barrel mounted in the chamber for rotation about a lateral axis, the barrel comprising a locked indicium and an unlocked indicium, wherein the barrel is rotatable between a lock-indicating position in which the locked indicium is visible and the unlocked indicium is not visible, and an unlock-indicating position in which the unlocked indicium is visible and the locked indicium is not visible; and
an activation carrier mounted in the shank and having a locking position and an unlocking position, and wherein the activation carrier is configured to rotate the barrel between the lock-indicating position and the unlock-indicating position as the activation carrier moves between the locking position and the unlocking position.

9. The status indicating handle assembly of claim 8 , further comprising a pushbutton mounted in the handle; and
wherein the pushbutton is configured to linearly drive the activation carrier between the locking position and the unlocking position as the pushbutton moves between a locked position and an unlocked position.

10. The status indicating handle assembly of claim 9 , wherein the pushbutton comprises an annular channel; and
wherein the activation carrier comprises a clip engaged with the annular channel such that the pushbutton is rotatable relative to the activation carrier.

11. The status indicating handle assembly of claim 8 , further comprising a first magnet mounted to the activation carrier and a second magnet mounted to the barrel; and
wherein magnetic interaction between the first magnet and the second magnet drives the barrel to rotate between the lock-indicating position and the unlock-indicating position as the activation carrier moves between the locking position and the unlocking position.

12. The status indicating handle assembly of claim 11 , further comprising a transmission mounted in the shank for rotation about the longitudinal axis, the transmission comprising a helical groove and a first gear;
wherein the activation carrier is mounted for rotation about a secondary longitudinal axis and includes a second gear; and
wherein the activation carrier has an engaged position in which the first gear is engaged with the second gear such that the activation carrier rotates in response to rotation of the transmission.

13. The status indicating handle assembly of claim 12 , wherein the activation carrier is slidable along the secondary longitudinal axis to a disengaged position in which the second gear is disengaged from the first gear such that the activation carrier is rotatable relative to the transmission.

14. The status indicating handle assembly of claim 12 , further comprising a plug rotatably mounted to the handle, wherein the plug is engaged with the helical groove such that rotation of the plug is correlated with longitudinal movement of the transmission.

15. A status indicating handle assembly, comprising:
a lever handle including a shank extending along a longitudinal axis and a grip portion extending in a lateral direction from the shank, the grip portion comprising a chamber;
a status indicator mounted in the chamber and having a first state in which the status indicator displays a first indicium and a second state in which the status indicator does not display the first indicium;
a transmission mounted for rotation about the longitudinal axis, the transmission including a first gear; and
an activation carrier mounted for rotation about a secondary longitudinal axis, wherein the activation carrier has an engaged position in which the first gear is engaged with a second gear such that the activation carrier rotates between a locking position and an unlocking position in response to rotation of the transmission; and
wherein the activation carrier transitio
