Detailed Description

Fig. 1 and 2 illustrate an example door handle assembly 20. Door handle assembly 20 includes a handle 22 and an escutcheon plate 24 facing handle 22, escutcheon plate 24 being attached to a mounting plate 26. The handle 22 is fixed relative to the mounting plate 26 by a hub assembly 28. In the example shown, the hub assembly 28 includes at least one of a hub body 30 and a handle adapter 32. However, hub assembly 28 may also include other components.

As shown in fig. 3, the adapter 32 is located near the first end 30A of the hub body 30 and the spindle 34 is located near the second end 30B of the hub body 30. The spindle 34 is slidably received within a spindle recess 36 in the second end 30B of the hub body 30 and is biased toward the extended position by a spring 37. The spindle 34 also includes a tip portion for engaging a lock or mortise (not shown).

As shown in fig. 3-5, the hub body 30 further includes an intermediate portion 30C separating the first end portion 30A from the second end portion 30B. First end 30A includes an attachment projection 38, attachment projection 38 having a pin aperture 40 for receiving a securing pin 42 for securing adapter 32 relative to hub body 30. The first end 30A also includes a securing flange 50, the securing flange 50 surrounding the protrusion 38 and at least partially defining an adapter recess 52 with the protrusion 38. In one example, the securing flange 50 extends axially from the intermediate portion 30C of the hub body 30. In the present disclosure, axial or axial and radial or radial are relative to a central longitudinal axis extending through the center of hub body 30, unless otherwise noted.

In the example shown, the fixation flange 50 includes a plurality of alignment protrusions 54 extending radially inward from an inner surface of the fixation flange 50. Adapter 32 includes a hub projection 56 that is received within adapter recess 52. In addition, the hub projection 56 includes an alignment notch 58, the alignment notch 58 being aligned with a corresponding one of the plurality of alignment projections 54.

Further, the adapter 32 comprises an outer hub protrusion 59, the outer hub protrusion 59 cooperating with a corresponding adapter recess 61 in the distal end of the fixation flange 50. Adapter 32 also includes a central opening 60 for receiving projection 38. The central opening 60 and the projection 38 include corresponding cross-sectional profiles. The engagement of the projections 38 with the central opening 60 and the engagement of the hub projections 56 with the adapter recesses 52 reduces relative movement between the adapter 32 and the hub body 30, thereby reducing relative play between the handle 22 and the hub body 30. Adapter 32 also includes an adapter aperture 62, adapter aperture 62 aligning with pin hole 40 in boss 38 to secure adapter 32 from moving longitudinally along boss 38.

Adapter 32 also includes at least one handle alignment notch 66 at the distal end of adapter 32 to facilitate alignment between handle 22 and adapter 32. Adapter 32 also includes at least one handle securing aperture 70 and handle 22 includes at least one corresponding handle aperture 72. A handle fixing pin 74 extends through the handle fixing hole 7 and the handle hole 72 to prevent the handle 22 from moving longitudinally relative to the adapter 32. In addition, the handle fixing pin 74 may be threaded.

Fig. 7 and 8 illustrate another example door handle assembly 120. Door handle assembly 120 is similar to door handle assembly 20 except as described below and shown in the figures. Door handle assembly 120 includes a handle 122 with escutcheon plate 24 facing handle 122 and attached to mounting plate 26. The handle 122 is fixed relative to the mounting plate 26 by a hub assembly 128. In the example shown, the hub assembly 128 includes at least one of the hub body 30 and the handle adapter 132. However, hub assembly 128 may also include other components.

As shown in fig. 9, the adapter 132 is formed as a ring and is positioned adjacent the first end 30A of the hub body 30 and at least partially engages the middle portion 30C and includes a central opening 180 for receiving the projection 38. The middle portion 30C includes a plurality of adapter notches 33 evenly circumferentially spaced around the hub body 30, the plurality of adapter notches 33 mating with corresponding hub projections 182 extending from the first end of the adapter 132. The adapter 132 includes a cylindrical cross-section and at least a portion of the inner surface 183 of the cylindrical portion of the adapter 132 is adjacent to or in contact with the radially outer surface 51 of the fixation flange 50. The distal end of the adapter 132 also includes a flange 184, the flange 184 extending radially inward and covering the distal end of the fixation flange 50. The flange 184 also includes an alignment tab 186, the alignment tab 186 being aligned with the alignment tab 54 on the mounting flange 50 and covering the distal end of the alignment tab 54.

As shown in fig. 7-8 and 9, the handle 122 includes a hub projection 123, the hub projection 123 fitting radially inward of a flange 184 on the adapter 132 and the securing flange 50 on the hub body 30. Hub projection 123 also includes an alignment notch 125, and alignment notch 125 is aligned with alignment projection 186 on adapter 132 and alignment projection 54 on hub body 30.

The engagement of hub projection 123 with adapter 132 and hub body 30 reduces relative movement between handle 122 and hub body 30. In addition, a securing pin 127 secures the handle 122 from longitudinal movement relative to the boss 38 by extending through a pin opening 129 in the handle 122 that is aligned with the pin hole 40 in the boss 38. In addition, the handle fixing pin 127 may be threaded.

While different non-limiting examples are shown with particular components, the examples of the disclosure are not limited to those particular combinations. Some features or characteristics from any non-limiting example may be used in combination with features or characteristics from any other non-limiting example.

It should be understood that like reference numerals designate corresponding or similar elements throughout the several views. It should also be understood that although a particular component arrangement is disclosed and illustrated in these exemplary embodiments, other arrangements may benefit from the teachings of the present disclosure.

The foregoing description is to be construed in an illustrative rather than a restrictive sense. One of ordinary skill in the art will appreciate that certain modifications may fall within the scope of the present disclosure. For that reason, the following claims should be studied to determine the true scope and content of this disclosure.
