Abstract
A landing gear has a rigid structure and a gear compartment. A leg has a wheeled first end on a rolling shaft, and a second end secured on the rigid structure. The leg rotates between a rolling position, letting the aircraft rolls, and a landing gear storage position. A brace has a first end secured on the rigid structure. A guide bar has a first end pivotably secured on the leg, and a second end secured on the second end of the brace by a pivot shaft. A jack is secured between the brace by a pivot connection with a shaft parallel to the rolling shaft, and the guide bar, by a pivot connection with a shaft parallel to the rolling shaft. A locking system locks either a second end of the brace or the second end of the guide bar against the leg in the rolling position.

1) Landing gear (100) for an aircraft (50), with a rigid structure (52) and a gear compartment (54), the landing gear (100) comprising:
- a leg (102) with a first end, on which there is secured at least one wheel (106) which is mobile in rotation around a rolling shaft (10), and a second end which is designed to be secured on the rigid structure (52) by means of a pivot connection (108) with a shaft parallel to the rolling shaft (10), the leg (102) being mobile in rotation between a rolling position, in which the leg (102) and the wheel (106) ensure that the aircraft (50) rolls, and a storage position in which the landing gear (100) is accommodated in the gear compartment (54);
- a brace (110) with a first end which is designed to be secured on the rigid structure (52) by means of a pivot connection (112) with a shaft parallel to the rolling shaft (10), and a second end;
- a guide bar (114) with a first end secured on the leg (102) by means of a pivot connection (116) with a shaft parallel to the rolling shaft (10), and a second end secured on the second end of the brace (110) by means of a pivot connection (118) with a shaft parallel to the rolling shaft (10);
- a jack (120) secured between the brace (110), by means of a pivot connection (126) with a shaft parallel to the rolling shaft (10), and the guide bar (114), by means of a pivot connection (128) with a shaft parallel to the rolling shaft (10);
- and
- a locking system (130) which is designed to lock at least one out of the second end of the brace (110), or the second end of the guide bar (114), against the leg (102), when the leg (102) is in the rolling position.
