Needle insertion mechanism for drug delivery device

A needle insertion mechanism for a drug delivery device, the needle insertion mechanism comprising:

• an actuation assembly having:
• an escapement assembly having a driving member, an urging member operably coupled with the driving member, and a pivotable member operably coupled with the urging member;
• and
• a rotatable link mechanism selectively coupled with the pivotable member of the escapement assembly;
• wherein the actuation assembly is movable between a storage state whereby the rotatable link mechanism is in a stationary storage position, a first operational state whereby the rotatable link mechanism is in a first stationary position, a second operational state whereby the rotatable link mechanism is in a second stationary position, and a third operational state whereby the rotatable link mechanism is in a third stationary position, wherein the third stationary position is different from the stationary storage position.

A needle insertion mechanism for a drug delivery device, the needle insertion mechanism comprising:

• an actuation assembly having:
• an escapement assembly having a driving member, an urging member operably coupled with the driving member, and a pivotable member operably coupled with the urging member such that the pivotable member rotates relative to the urging member;
• and
• a rotatable link mechanism selectively coupled with the pivotable member of the escapement assembly such that when the pivotable member is coupled with the rotatable link mechanism, a position of the rotatable link mechanism is maintained;
• wherein the actuation assembly is movable between a storage state whereby the rotatable link mechanism is in a stationary storage position, a first operational state whereby the rotatable link mechanism is in a first stationary position, a second operational state whereby the rotatable link mechanism is in a second stationary position, and a third operational state whereby the rotatable link mechanism is in a third stationary position.
