Patent attributes
The descender comprises a handle and a cam that are movable between a securing position and a sliding position of the rope. The cam defines a first stop and a second pin. The handle has a first pin coming into contact with the first stop to form a first mechanical link and a second stop coming into contact with the second pin. Movement of the handle results in movement of the cam between the securing and sliding positions. In a threshold position of the handle, the first mechanical link is interrupted and the cam returns to the securing position. The second stop is movable with respect to the handle by means of a spring. When movement of the handle takes place, the second pin comes into contact with the second stop before the handle stresses a spring and reaches the threshold position.
