An adjustable size suitcase includes a main body having a top section, a middle section and a bottom section that define a hollow interior space. A telescopic handle extends upward from the main body and a plurality of omnidirectional wheels are positioned along the bottom end of the main body. A frame is positioned within the hollow interior space of the main body and includes an upper frame assembly, a middle frame assembly and a lower frame assembly. The upper frame assembly includes a plurality of vertical frame members that are slidingly engaged to complementary located lower vertical frame members to permit vertical movement of the upper frame assembly relative to the lower frame assembly. An actuator is mechanically linked to a plurality of latches positioned within the bottom ends of each upper vertical frame member to selectively transition the suitcase between a first, second and third size.

A luggage system with a wardrobe element which extends from the luggage portion and supports a crossbar for hanging clothing or costumes. An arm extends away from the crossbar for supporting a privacy curtain. The wardrobe element is secured within the sides of the luggage, and the opening of the luggage can be opened and closed without needing to store the wardrobe element. In a preferred embodiment, the wardrobe element includes two pairs of structural legs extending out of respective pockets within the luggage, the legs terminating at the crossbar.

A wheeled luggage case comprises (a) a storage chamber, (b) a cover defining an opening on at least one side of the storage chamber for providing ready access therein and at least two labyrinth axle-free wheels operatively connected to the chamber for towing the case along a ground surface. The labyrinth axle-free wheel comprises an internal rim, an external rim provided with a ground interface, rollers being rotatably disposed within a roller spacer between the internal and external rims in a uniform circumferential manner by means of a spacer and external covers. A labyrinth type dust passage in the wheel is defined by the rims and the external plates mechanically connected to the internal rim.

A wheeled carrier including a rigid base having a bottom side, opposing front and rear sides extending upward from the bottom side, and opposing first and second lateral sides extending upward from the bottom side, a body extending upward from the base defining an interior between the base and an apex of the body, a pair of wheels connected to the base, the pair of wheels configured to rotate about an axis proximate to the rear side of the base, a telescoping handle assembly including two telescoping legs, each having a proximal end attached to the base and a distal end, the telescoping handle assembly including a handle connecting the distal ends of the two telescoping legs and extending over the apex of the body, and a pair of backpack straps attached to the body.

A method for manufacturing a quadrangular shell having five faces and non-developable trihedral connectors between the faces. Plies having continuous fibers are cut to cover the five faces of the shell outside of the trihedral connector zones. Four connector components consolidated in the shape of the trihedral connectors are obtained. Each of the components includes an integration zone between the plies. Plies are positioned and laid up. The four consolidated components are inserted in the trihedral connection zones by inserting the integration zones between two plies to form an assembly obtain a preform. The preform is placed in a tool and the consolidation of the stack of fibrous plies is performed by subjecting the assembly to a predetermined pressure/temperature cycle.

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.

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.

A freely-transformable multipurpose carrier bag. The freely-transformable multipurpose carrier bag can be conveniently moved in the form of a carrier bag both indoors and outdoors and irrespective of the size of a place, can be transformed into and used as a table having a chair, can expose a pre-embedded electronic device component to the outside if needed, so as to enable a user to enjoy various forms of entertainment such as watching TV, using a computer, playing a game, or singing along with music, and can also enable the user to perform a business task, so that the user can universally perform both work and play.

The suitcase with wagon-style cart capability is an item of luggage. The suitcase with wagon-style cart capability is formed as a cart. The suitcase with wagon-style cart capability: a) contains one or more domestic articles of a client; and, b) transports additional luggage items over a supporting surface. The suitcase with wagon-style cart capability is a rolling structure. The suitcase with wagon-style cart capability incorporates a suitcase, a plurality of telescopic handles, a plurality of casters, and a plurality of wheels. The plurality of telescopic handles, the plurality of casters, and the plurality of wheels attach to the exterior surface of the suitcase. The suitcase is a container used to store one or more domestic articles of the client. The exterior surfaces of the suitcases form one or more horizontally oriented supporting surfaces on which the additional luggage items of the client are placed for transport.
