Medicament Delivery Device Comprising a Locking Mechanism Having a Lever

Abstract

Medicament delivery device comprising a movable guard ( 10 ) being movable between a proximal and a distal position and a locking mechanism ( 15 ) having a level ( 16 ), the lever ( 16 ) restricting movement of an actuation locking member ( 24 ) until the movable guard is positioned in a distal position and the lever ( 16 ) restricting movement of the guard ( 10 ) in a proximal position after actuation of the device.

1 - 16 . canceled 
     
     
         17 . A medicament delivery device, comprising:
 a guard movable between a proximal position and a distal position;   an actuation locking member;   a medicament container holder arranged within the guard; and   a locking mechanism comprising a lever, wherein a distal end of the lever includes a protrusion that directly contacts the guard to thereby restrict movement of the guard in the proximal position prior to actuation of the medicament delivery device, and wherein the lever is pivotally mounted directly to the medicament container holder such that the lever pivots around a pivot axis of the lever in two directions.   
     
     
         18 . A The medicament delivery device of  claim 17 , wherein the actuation locking member surrounds the medicament container holder. 
     
     
         19 . A The medicament delivery device of  claim 17 , wherein the lever is formed integral with the medicament container holder. 
     
     
         20 . A The medicament delivery device of  claim 17 , wherein the actuation locking member is a ring-shaped or sleeve-shaped member surrounding the medicament container holder. 
     
     
         21 . A The medicament delivery device of  claim 17 , wherein the lever is connected to a middle portion of the medicament container holder. 
     
     
         22 . A The medicament delivery device of  claim 17 , wherein the lever is put in a tensioned state by the guard when the guard is moved in a distal direction. 
     
     
         23 . A The medicament delivery device of  claim 22 , wherein the tensioned state of the lever causes the lever to release the guard to thereby enable the guard to transition from the proximal position to the distal position. 
     
     
         24 . A The medicament delivery device of  claim 17 , wherein the guard and the actuation locking member are configured to contact less than the entire lever. 
     
     
         25 . A The medicament delivery device of  claim 17 , wherein the actuation locking member comprises at least one proximally extending tongue, and wherein the at least one proximally extending tongue is configured to contact the lever as the guard transitions from the proximal position to the distal position. 
     
     
         26 . A The medicament delivery device of  claim 17 , wherein the lever comprises a longitudinally extending beam. 
     
     
         27 . A The medicament delivery device of  claim 17 , wherein the guard comprises at least two distally directed tongues, wherein each of the at least two distally directed tongues includes a proximal end directly attached to the guard and a distal free end extending away from the guard in a distal direction. 
     
     
         28 . A The medicament delivery device of  claim 27 , wherein the at least two distally directed tongues are integral with a distal end of the guard. 
     
     
         29 . A The medicament delivery device of  claim 17 , wherein the lever is at least partly overlapped by the actuation locking member when the medicament delivery device is actuated.
