Abstract: An item of luggage includes an extendable and retractable handle mechanism having a handle axle to which a grip portion is mechanically connected. An elongate member of specific cross-section is mounted to be movable in translation relative to a fixed sheath and a locking/unlocking system. The locking/unlocking system includes a bushing and partly housed in the elongate member. In a first position of the grip portion, the locking/unlocking system is configured to compress the bushing such that it is tightly applied against an inside face of the sheath to keep the elongate member fixed in the sheath, thus locking the handle in a selected position. In a second position of the grip portion, the locking/unlocking system is configured to decompress the bushing to enable a free sliding of the elongate member in the sheath, thus unlocking the handle.

Abstract: An item of luggage includes an extendable and retractable handle mechanism having a handle axle to which a grip portion is mechanically connected. An elongate member is mounted to be movable in translation relative to a fixed sheath partly housing a locking/unlocking system, which is mechanically connected to elongate member. An interface system is actuated by the handle axle and actuates the locking/unlocking system. A support member forms a housing for a portion of the handle axle and the interface system. The support member includes a wall forming a guide and a stop for rotational movement of the interface system and of the handle axle between first and second positions of the grip portion and the handle axle. In the first position, the locking/unlocking system locks the handle in a selected position. In the second position, obtained by the rotation of the grip portion, the locking/unlocking system unlocks the handle.
