Existing door handle assemblies include various components that are assembled and mounted to a door. In order to change a style of handle on the door handle assembly, the entire door handle assembly must be replaced.
In one exemplary embodiment, a handle assembly includes a hub body that extends along a central longitudinal axis that has a first end portion that includes a first set of handle adapter engagement features and a second set of handle adapter engagement features. A handle adapter includes at least one of a first set of hub engagement features for engaging the first set of handle adapter engagement features or a second set of hub engagement features for engaging the second set of handle adapter engagement features. A handle engages both the handle adapter and the hub body.
In a further embodiment of any of the above, the first set of handle adapter engagement features are located radially inward from the second set of handle adapter engagement features relative to the central longitudinal axis of the hub body.
In a further embodiment of any of the above, a protrusion extends longitudinally from the first end of the hub body and located within an opening in the handle adapter.
In a further embodiment of any of the above, the first set of handle adapter engagement features includes at least one first protrusion or at least one first recess. The first set of handle adapter engagement features includes the other of the at least one first protrusion and the at least one first recesses.
In a further embodiment of any of the above, a handle adapter retention pin extends through corresponding openings in the handle adapter and the protrusion.
In a further embodiment of any of the above, the retention pin is spaced from the handle.
In a further embodiment of any of the above, a handle retention pin is in engagement with the handle and the handle adapter and spaced from the protrusion.
In a further embodiment of any of the above, the at least one first protrusion includes a handle adapter protrusion located at a proximal end of the handle adapter. The at least one first recess includes a handle adapter recess formed by a retention flange on the hub body.
In a further embodiment of any of the above, the handle adapter forms a ring.
In a further embodiment of any of the above, the at least one first protrusion includes a handle adapter protrusion located at a proximal end of the handle adapter and on a perimeter of the ring. The at least one first recess includes hub recess formed adjacent a perimeter of the hub.
In a further embodiment of any of the above, the handle adapter includes an inner surface that engages a retention flange on the hub body.
In a further embodiment of any of the above, the retention flange includes a plurality of protrusions on a radially inner side of the retention flange. The ring includes a flange that has alignment protrusions that extend radially inward from the flange and are aligned with a corresponding one of the plurality of protrusions on the radial inner side of the retention flange.
In a further embodiment of any of the above, the handle includes a hub protrusion that has a plurality of alignment recesses that align with corresponding ones of the plurality of protrusions on the radially inner side of the retention flange.
In a further embodiment of any of the above, a retention pin extends through the handle and protrusion extending from the first end of the hub body.
In another exemplary embodiment, a method of assembling a door handle includes the step of positioning a handle adapter adjacent a first end portion of a hub body. One of a first set of handle adapter engagement features or a second set of handle adapter engagement features are engaged on the hub body with a corresponding one of a first set of hub engagement feature or a second set of hub engagement features on the handle adapter. A handle is engaged with the handle adapter.
In a further embodiment of any of the above, the first set of handle adapter engagement features are located radially inward from the second set of handle adapter engagement features relative to the central longitudinal axis of the hub body.
In a further embodiment of any of the above, the first set of handle adapter engagement features includes at least one first protrusion or at least one first recess. The first set of handle adapter engagement features includes the other of the at least one first protrusion and the at least one first recesses.
In a further embodiment of any of the above, the at least one first protrusion includes a handle adapter protrusion located at a proximal end of the handle adapter. The at least one first recess includes a handle adapter recess formed by a retention flange on the hub body.
In a further embodiment of any of the above, the handle adapter forms a ring and the at least one first protrusion includes a handle adapter protrusion located at a proximal end of the handle adapter and on a perimeter of the ring. The at least one first recess includes hub recess formed adjacent a perimeter of the hub.
In a further embodiment of any of the above, the handle adapter includes an inner surface that engages a retention flange on the hub body.

In the illustrated example, the retention flange 50 includes a plurality of alignment protrusions 54 that extend radially inward from an inner surface of the retention flange 50. The adapter 32 includes a hub protrusion 56 that is accepted within the adapter recess 52. Additionally, the hub protrusion 56 includes alignment recesses 58 that are aligned with a corresponding one of the plurality of alignment protrusions 54.
Additionally, the adapter 32 includes exterior hub protrusions 59 that mate with corresponding adapter recesses 61 in a distal end of the retention flange 50. The adapter 32 also includes a central opening 60 for accepting the protrusion 38. The central opening 60 and the protrusion 38 include a corresponding cross sectional profile. The engagement of the protrusion 38 with the central opening 60 and the hub protrusion 56 with the adapter recess 52 provides a reduction in relative movement between the adapter 32 and the hub body 30 to reduce relative play between the handle 22 and the hub body 30. The adapter 32 also includes an adapter aperture opening 62 that is aligned with the pin aperture 40 in the protrusion 38 to secure the adapter 32 from moving longitudinally along the protrusion 38.
The adapter 32 also includes at least one handle alignment recess 66 located at a distal end of adapter 32 to facilitate alignment between the handle 22 and the adapter 32. The adapter 32 also includes at least one handle retention aperture 70 and the handle 22 includes at least one corresponding handle aperture 72. A handle retention pin 74 extends through the handle retention aperture 70 and the handle aperture 72 to prevent the handle 22 from moving longitudinally relative to the adapter 32. Additionally, the handle retention pin 74 could be threaded.

The engagement of the hub protrusion 123 with the adapter 132 and the hub body 30 reduces relative movement between the handle 122 and the hub body 30. Additionally, a retention pin 127 fixes the handle 122 from moving longitudinally relative to the protrusion 38 by extending through a pin opening 129 in the handle 122 that is aligned with the pin aperture 40 in the protrusion 38. Furthermore, the handle retention pin 127 could be threaded.
Although the different non-limiting examples are illustrated as having specific components, the examples of this disclosure are not limited to those particular combinations. It is possible to use some of the components or features from any of the non-limiting examples in combination with features or components from any of the other non-limiting examples.
It should be understood that like reference numerals identify corresponding or similar elements throughout the several drawings. It should also be understood that although a particular component arrangement is disclosed and illustrated in these exemplary embodiments, other arrangements could also benefit from the teachings of this disclosure.
The foregoing description shall be interpreted as illustrative and not in any limiting sense. A worker of ordinary skill in the art would understand that certain modifications could come within the scope of this disclosure. For these reasons, the following claims should be studied to determine the true scope and content of this disclosure.
