Abstract

A handleset includes a housing, a spindle sleeve, a handle, a coupler, and a spindle. The spindle sleeve includes an aperture, and is rotatably mounted to the housing. The handle is mounted to the spindle sleeve and includes a recess aligned with the aperture. The coupler is movably mounted in the aperture for movement between a decoupling position and a coupling position. The coupler in the coupling position is disengaged from the recess and does not prevent removal of the handle from the spindle sleeve. The coupler in the coupling position extends into the recess and prevents removal of the handle from the spindle sleeve. The spindle is movably received in the spindle sleeve and selectively retains the coupler in the coupling position.

First claim

What is claimed is:

1. A handleset, comprising:
a housing;
a spindle sleeve including an aperture, wherein the spindle sleeve is rotatably mounted to the housing;
a handle mounted to the spindle sleeve, the handle comprising a recess aligned with the aperture;
a coupler movably mounted in the aperture for movement between a decoupling position and a coupling position, wherein the coupler in the decoupling position is disengaged from the recess and does not prevent removal of the handle from the spindle sleeve, and wherein the coupler in the coupling position extends into the recess and prevents removal of the handle from the spindle sleeve; and
a spindle movably received in the spindle sleeve and selectively retaining the coupler in the coupling position.

2. The handleset of claim 1 , wherein the spindle sleeve further comprises a second aperture;
wherein handle further comprises a handle aperture aligned with the second aperture; and
wherein a threaded fastener extends between the second aperture and the handle aperture.

3. The handleset of claim 1 , wherein the spindle is slidable relative to the spindle sleeve between a retaining position in which the spindle retains the coupler in the coupling position, and a releasing position in which the spindle permits movement of the coupler to the decoupling position.

4. The handleset of claim 1 , wherein the spindle sleeve extends proximally from the housing and the coupler is positioned proximally of the housing; and
wherein the spindle includes a proximal end portion and an opposite distal end portion; and
wherein the spindle has a retaining position in which the proximal end portion is engaged with the coupler and the distal end portion is positioned distally of the housing.

5. The handleset of claim 1 , wherein the handleset lacks a lock cylinder.

6. The handleset of claim 1 , wherein the coupler is not biased toward either of the decoupling position or the coupling position.

7. The handleset of claim 1 , wherein the handle is mounted to the spindle sleeve in a first orientation;
wherein the handle further comprises a second recess opposite the recess; and
wherein the handle is operable to be mounted to the spindle sleeve in a second orientation in which the aperture is aligned with the second recess and the coupler is operable to enter the second recess.

8. The handleset of claim 1 , wherein at least one side of the aperture is sized and shaped to prevent the coupler from exiting the aperture from the at least one side.

9. The handleset of claim 1 , further comprising at least one additional coupler having an additional decoupling position and an additional coupling position;
wherein the spindle sleeve further comprises at least one additional aperture in which the at least one additional coupler is seated for movement between the additional decoupling position and the additional coupling position;
wherein the handle further comprises at least one additional recess aligned with the at least one additional aperture and operable to receive a portion of the at least one additional coupler when the at least one additional coupler is in the additional coupling position; and
wherein the spindle selectively retains the each of the at least one additional coupler in the additional coupling position.

10. The handleset of claim 9 , wherein removal of the handle from the spindle sleeve is selectively prevented only by the coupler and the at least one additional coupler.

11. The handleset of claim 9 , wherein a proximal end portion of the spindle is divided into at least two spindle portions by at least one slit that permits flexing of the at least two spindle portions.

12. The handleset of claim 9 , wherein the handle further comprises an annular channel defining the recess and the at least one additional recess.

13. The handleset of claim 1 , wherein the recess has one of a V-shaped cross-section or a U-shaped cross-section.

14. A lockset comprising the handleset of claim 1 , the lockset further comprising a chassis, the chassis comprising:
a latchbolt mounted for movement between an extended position and a retracted position; and
a hub operably connected with the latchbolt such that rotation of the hub drives the latchbolt between the extended position and the retracted position;
wherein the spindle is rotationally coupled with the hub.

15. The handleset of claim 1 , wherein the spindle is configured to engage the coupler during insertion of the spindle into the spindle sleeve to thereby drive the coupler from the decoupling position to the coupling position.

16. The handleset of claim 15 , wherein the coupler is configured to roll along the spindle during insertion of the spindle into the spindle sleeve.

17. The handleset of claim 1 , wherein the coupler is captured between the handle and the spindle such that the coupler is inoperable to exit the handle in a radially-outward direction.

18. The handleset of claim 1 , wherein the coupler is at least partially received in the spindle sleeve when the coupler is in the decoupling position.

19. A lockset, comprising:
a chassis comprising a first hub, wherein the first hub is rotatable;
a latchbolt operably connected with the chassis such that each of the first hub and the second hub is operable to drive the latchbolt between an extended position and a retracted position; and
a first handleset removably mounted to a first side of the chassis, the first handleset comprising:
a first housing;
a first handle rotatably mounted to the first housing;
a first spindle rotationally coupled with the first handle and the first hub; and
a coupler operable to selectively prevent removal of the first handle from the first housing, the coupler having a coupling position in which the coupler prevents removal of the first handle from the first housing, the coupler having a decoupling position in which the coupler does not prevent removal of the first handle from the first housing;

wherein, when the first handleset is mounted to the first side of the chassis, the first spindle is retained in a retaining position in which the first spindle retains the coupler in the coupling position; and
wherein, when the first handleset is removed from the first side of the chassis, the first spindle is movable to a releasing position in which the first spindle does not prevent movement of the coupler from the coupling position to the decoupling position.

20. The lockset of claim 19 , wherein the first handleset further comprises a first spindle sleeve rotatably mounted to the first housing;
wherein the first spindle sleeve is engaged between the first handle and the first spindle and movably supports the coupler; and
wherein the first housing comprises a first spring cage engaged with the first spindle sleeve and biasing the first spindle sleeve, the first handle, the first spindle, and the first hub to a home position.

21. The lockset of claim 20 , wherein the first handleset further comprises a fastener operable to couple the first handle with the first spindle sleeve; and
wherein the coupler is operable to prevent removal of the first handle from the first spindle sleeve independently of the fastener.

22. The lockset of claim 19 , wherein the chassis further comprises a second hub; and
wherein the lockset further comprises a second handleset removably mounted to a second side of the chassis, the second handleset comprising:
a second housing;
a second handle rotatably mounted t
