Claims19
A hub assembly for a door handle comprising:
- a hub body extending along a longitudinal axis having a first end portion including a spindle recess and a second end portion including a handle attachment protrusion, wherein the hub body includes a mid-portion that connects the first end portion and the second end portion;
- a spindle slideably received within the spindle recess in the first end of the hub body, and wherein the spindle comprises a body portion with a spring recess that is open at a first end of the body portion and closed at a second end of the body portion to provide a spring contact surface, wherein the body portion has a first pair of opposing longitudinally extending sides and a second pair of opposing longitudinally extending sides giving the body portion a rectangular shape and an elongated longitudinally extending slot is located in at least one of the first pair of opposing longitudinally extending sides and is co-axial with the longitudinal axis;
- and
- a spring having a first end in contact with either the first end portion or the mid-portion of the hub body and the spring having a second end extending into the spring recess and engaging the spring contact surface, and wherein the spring is co-axial with the longitudinal axis.

A method of operating a hub assembly for a door handle comprising the steps of:
- providing a spindle which comprises a body portion with a spring recess that is open at a first end of the body portion and closed at a second end of the body portion to provide a spring contact surface, wherein the body portion has a first pair of opposing longitudinally extending sides and a second pair of opposing longitudinally extending sides giving the body portion a rectangular shape and an elongated longitudinally extending slot is located in at least one of the first pair of opposing longitudinally extending sides, wherein the elongated longitudinally extending slot is co-axial with a central longitudinal axis of the hub assembly;
- providing a hub body extending along the central longitudinal axis and having a first end portion including a spindle recess, a second end portion including a handle attachment protrusion, and amid-portion that connects the first end portion and the second end portion;
- slideably engaging the spindle in the hub body, the spindle engaging within the spindle recess in the hub body to vary a distance between a tip portion of the spindle and the hub body;
- biasing the spindle towards an extended position relative to the hub body with a spring having a first end in contact with either the first end portion or the mid-portion of the hub body, and a second end extending into the spring recess and engaging the spring contact surface, and wherein the spring is co-axial with the central longitudinal axis;
- and
- limiting movement of the spindle relative to the hub body with a pin at least partially located in an elongated longitudinally extending slot in the spindle and within a pin aperture in the hub body.
