Abstract
An assembly includes a clutch member and a drive member movable relative to one another between a first relative position and a second relative position, in the first relative position, the clutch member and/or the drive member is rotatable relative to a housing, in the second relative position, the deflectable feature is arranged to prevent rotation of the clutch member and/or of the drive member relative to the housing, and wherein the deflectable feature and the interaction feature are arranged such that, when the clutch member and the drive member are moved relative to one another from the first relative position into the second relative position, the deflectable feature and the interaction feature mechanically interact in order to deflect the deflectable feature.
Claims19
An assembly for a drug delivery device, the assembly comprising:
- a housing;
- a clutch member, the clutch member being a clutch sleeve;
- and
- a drive member, wherein the drive member is received in the clutch member, wherein:
- the clutch member is provided with at least one deflectable feature, the at least one deflectable feature being an axially oriented finger arranged to be deflected radially and being provided at a distal end of the clutch member,
- the drive member is provided with at least one interaction feature,
- the clutch member and the drive member are movable relative to one another between a first relative position and a second relative position,
- in the first relative position, the clutch member and/or the drive member is rotatable relative to the housing,
- in the second relative position, the at least one deflectable feature is arranged to prevent rotation of the clutch member and/or of the drive member relative to the housing, and
- the at least one deflectable feature and the at least one interaction feature are arranged such that, when the clutch member and the drive member are moved relative to one another from the first relative position into the second relative position, the at least one deflectable feature and the at least one interaction feature mechanically interact in order to deflect the at least one deflectable feature.
