Mechanism for locking a door in circular translation

An assembly with a circular translation door locking mechanism (2) (1a) comprising;

• a vehicle semi-plug door (1a) and a body from which is cut at least one opening creating a door frame (1c), the mechanism (2) having a handle (3) activating a rotation of the door (1a) on itself in the door frame (1c) and connecting the door (1a) to the door frame (1c) by two guide entities of the door in circular translation:
• an arm-entity (4a) comprising an arm (4b) and a forearm (4c) rotating with respect to each other along an axis (4d) parallel to the axis of rotation (1d) of the door (1a), the arm (4b) and the forearm (4c) being connected respectively to the door frame (1c) and the door (1a),
• a guide entity (5a) having a connecting rod (5b) and a lever (5c) rotating relative to each other along an axis (5d) parallel to the axis of rotation (1d) of the door (1a) and connected respectively to the door frame (1c) and to the axis (4d) of rotation of the arm entity (4a);
• and
• the locking mechanism (2) being characterized in that it comprises at least one means of blocking the lever (5c) and the forearm (4c) in relation to the door (1a) as well as a blocking element of the handle (3) during the circular translation of the door.
