Inhalator comprising a dosage counting device

The inhalator for dispensing an aerosol, comprising:

• a dosage counting unit (11),
• a housing device (2,3) having a stationary part (17),
• an aerosol dispensing container (1) arranged in the housing device (2, 3) and slidable relative to the housing device (2, 3) in a direction of a longitudinal axis of the aerosol dispensing container (1),
• a first counting ring (12) arranged coaxially to the longitudinal axis (X) of the aerosol dispensing container (1) and rotatable about the longitudinal axis (X),
• a second counting ring (13) arranged coaxially to the first counting ring (12) and rotatable relative to the first counting ring (12),
• a counting ring switching device (16) for rotating the first counting ring (12) upon actuation of the inhalator,
• a coupling device (24, 25, 26, 27) coupling the second counting ring (13) to the first coupling ring (12) for a stepwise rotation by a counting step of the second counting ring (13) together with the first counting ring (12),
• wherein the counting ring switching device (16) has an actuation portion (19) and a switching finger (20) coupled to the actuation portion (19),
• wherein the first counting ring (12) has control elements (23),
• wherein the switching finger (20) engages the control elements (23) for rotation of the first counting ring (12) in a counting direction, and
• wherein the switching finger (20) is spaced from the longitudinal axis (X) and is arranged at a slant to the longitudinal axis (X) and engages the control elements (23) axially, further comprising
• an elastically yielding arm part (21) coupled with the switching finger (20) via the actuating portion (19) such that the arm part (21) and the switching finger (20) form an elbow joint mechanism, the arm part (21) being supported on the stationary part (17).
