EP4249016A1 — Actuating unit for a drug delivery device and related items

USPTO Abstract

Disclosed is an actuating unit (301) for a drug delivery device (100), comprising:- A support structure (300) extending along a longitudinal axis (A) between a distal (D) portion of the support structure (300) and a proximal (P) portion of the support structure (300), and- An interface unit (IF1, IF2) arranged within the support structure (300) and comprising a coupling portion (340) and an actuating portion (332),wherein the coupling portion (340) is configured to interact with a rotating member comprising a plurality of teeth (404a) and rotating around a rotation axis (A) that is parallel or coaxial to the longitudinal axis (A),wherein the actuating portion (332) is configured to interact with an electrical component (Sw), wherein the interface unit (IF1, IF2) is configured to interact with the plurality of teeth (404a) of the rotating member and to convert a rotational movement (R) of the rotating member to an axial displacement (Arr7Bp) of the coupling portion (340) in a first direction relative to the longitudinal axis (A), e.g. from a first axial position to a second axial position, and to a radial displacement of at least a part of the coupling portion (340) relative to the longitudinal axis, and wherein the axial displacement and/or the radial displacement of the coupling portion (340) displaces the actuating portion (332).
