Patent ID: 7959107

Claim:
A hinge device of a nacelle cowling of an aircraft engine on a supporting structure, comprising: a first fitting which is securely mounted on one of the nacelle cowling or the supporting structure; a second fitting which is securely mounted to the other of the nacelle cowling or the supporting structure; and a link rod connected to said first and second fittings and extending in a longitudinal link rod direction, wherein said link rod includes a first end mounted on the first fitting by a first end connection including an assembly pin which is centered on a hinge axis of the nacelle cowling a second end mounted on said second fitting by a second end connection, wherein said link rod is further mounted on said second fitting by an intermediate connection including a pivot pin slidably housed in a hole formed on one of the second fitting or the link rod, and the pivot pin is supported by the other of the second fitting or the link rod, wherein said second end connection includes a guide pin slidably housed in a guide ramp, wherein said second end connection and intermediate connection are designed so as to cause, upon rotation of the link rod about the pivot pin, a relative movement of said guide pin in said guide ramp which causes a relative movement of the pivot pin in the hole of said intermediate connection, and wherein the pivot pin is slidably housed in the hole formed on one of the second fitting or the link rod in a plane orthogonal to an axis of rotation of the pivot pin.
