Aircraft landing gear provided with a leaf spring locking device

A landing gear for an aircraft, comprising:

• a strut configured to be mounted on an aircraft structure so as to move between an extended position and a retracted position;
• at least one bracing member configured to hold the strut in the extended position, and comprising a first bracing connecting rod configured to be hingedly coupled to the structure of the aircraft and a second bracing connecting rod hingedly coupled to the first bracing connecting rod and to the strut;
• a stabilizing member configured to hold the first and second bracing connecting rods in an aligned position, and comprising a first stabilizing connecting rod hingedly coupled to a second stabilizing connecting rod, the second stabilizing connecting rod being hingedly coupled to the first bracing connecting rod;
• and
• at least one spring configured to resiliently return the hinges of the first and second stabilizing connecting rods into the aligned positions;
• wherein the at least one spring is a leaf spring arranged to be brought into a resiliently deformed state under a bending force (P, P′) when the hinges of the first and second stabilizing connecting rods move from their generally aligned position, and to avoid being subjected to the bending force and be in one state of lesser deformation when the strut is between the retracted position and first intermediate position between the retracted position and the extended position than when said strut is between the first intermediate position and a second intermediate position between the first intermediate position and the extended position, the state of lesser deformation being a state of non-zero deformation and remaining unchanged when the strut is between the retracted position and an first intermediate position.
