The invention relates to raisable landing gear including a shock absorber having a strut and a sliding rod, together with a two-alignment hinged side-brace. According to the invention, unlocking means are provided to break the secondary alignment, thereby breaking the main alignment while the landing gear is being raised, said means being essentially constituted by a lever mounted to rotate on one of the arms of the main alignment, and by a motor and gear box assembly for driving said rotary lever in rotation and further including an unlocking arm that, when said motor and gear box assembly is in action, co-operates with the lower arm of the secondary alignment to break said secondary alignment. Return means are also associated with the rotary lever to ensure that it returns to its initial position when the landing gear is raised.

Raisable landing gear comprising a shock absorbing strut hinged to the structure of an airplane, having a sliding rod that carries a set of wheels, and a two-alignment hinged side-brace with a main alignment that connects the shock absorbing strut to the structure of the airplane and constituted by an upper arm and a lower arm that are hinged together, and a secondary alignment connecting one of the arms of the main alignment to said structure of the airplane, said secondary alignment likewise being constituted by an upper arm and a lower arm that are hinged together, unlocking means also being provided to break the secondary alignment and consequently to break the main alignment when the landing gear is raised, wherein the unlocking means is essentially constituted by a lever mounted to rotate on that arm of the main alignment on which the secondary alignment is hinged, and by a motor and gear box assembly driving said rotary lever in rotation, said lever including an unlocking arm that, on actuation of said motor and a gear box assembly, co-operates with the lower arm of the secondary alignment to break said secondary alignment, return means also being associated with said rotary alignment to ensure that it returns to its initial position when the landing gear is raised.
