A system to wheel multiple pieces of luggage simultaneously is disclosed herein. The luggage coupling system Includes connecting straps along the bodies of the luggage. Furthermore the, coupling devices link the wheels of the luggage together to form one system. Additionally, the system includes a track assembly that is mounted on to the back end of each luggage. The track assembly allows for a user to easily transport the luggage system up and down a staircase. The system further includes a battery pack to allow a user to charge their mobile devices as they are transporting their luggage.

One or more devices are provided that are configured to detachably engage within a modular system. The one or more devices are positionable to provide a support structure upon which work can be performed.

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.

An axle-free wheel comprising: an outer rim member having a ground interface on an external surface thereof and an outer ball race or rolling race on an inner surface thereof; an inner rim member having an inner ball or rolling race on an outer surface thereof.

An article of luggage includes a trolley system and a garment bag. The garment bag includes a top boundary, a bottom boundary, a left side boundary, a right side boundary, a top surface and a rear surface, and is provided on top of the trolley system. The semi-rigid base panel is provided one of under or over the rear surface, to physically insulate contents of the garment bag from the trolley system. The article further includes side flaps, the side flaps configured to respectively releasably attach to corresponding upper and lower portions of the left and right side boundaries of the garment bag, such that an inner surface of each side flap and the top surface of the garment bag define an interior cavity of the article in a closed state.

A rotational sliding bearing having a static part and a mobile part, each having a sub-shell with a sliding surface, each surface arranged within an angular range of max. 180° relative to the rotational axis in the direction of rotation of the bearing, and in a closed rest position, the sub-shells of all parts together form a bearing bush, the mobile part is arranged to pivot about a pivot axis for opening the bearing relative to the static part, such that a shaft mounted in the bearing is released in a release position, and the mobile part is shaped such that, based on the sliding surface position relative to the rotational axis, in the closed rest position, a translation of a shaft accommodated in the bearing is prevented transversely to the rotational axis and in the direction of the pivot axis of the mobile part or in the counter direction.

A luggage component includes a case extending between a lower end and an upper end and includes a front wall, a rear wall and a side wall extending therebetween. At least one wheel extends from the rear wall proximate the upper end. At least one fixed position wheel extends from the side wall along the lower end proximate the front wall. At least one multi-function wheel extends relative to the side wall and the rear wall such that the multi-function wheel is positionable to provide a rolling surface relative to the side wall and positionable to provide a rolling surface relative to the rear wall. The luggage component also includes an adjustable handle assembly which includes a housing extending along the rear wall with an end portion thereof extending beyond the case upper end. The end portion defines a stop surface and at least one slot extending parallel to the side wall. At least one handle shaft is configured to extend from the housing in a direction parallel with the rear wall. The handle shaft is configured to pivot within the slot when the at least one handle shaft is fully extended from the housing.

A rollable luggage assembly for piggybacking a second suitcase on a first suitcase includes a plurality of first rollers that is coupled to a bottom of the first suitcase. A first handle is selectively extensible from the first suitcase so that the first handle is positioned above and perpendicular to a top of the first suitcase. The first handle is configured to be grasped in a hand of a user to urge the first suitcase to roll across a surface. A plate, which is coupled to and is selectively extensible from the bottom of the first suitcase, is selectively positionable in a retracted configuration, wherein the plate is stowed adjacent to the bottom, and an extended configuration, wherein the plate extends from and is perpendicular to a front of the first suitcase. The plate is configured to position an article so that the article is locomoted with the first suitcase.

A rotational sliding bearing having a static part and a mobile part, each having a sub-shell with a sliding surface, each surface arranged within an angular range of max. 180° relative to the rotational axis in the direction of rotation of the bearing, and in a closed rest position, the sub-shells of all parts together form a bearing bush, the mobile part is arranged to pivot about a pivot axis for opening the bearing relative to the static part, such that a shaft mounted in the bearing is released in a release position, and the mobile part is shaped such that, based on the sliding surface position relative to the rotational axis, in the closed rest position, a translation of a shaft accommodated in the bearing is prevented transversely to the rotational axis and in the direction of the pivot axis of the mobile part or in the counter direction.

An article of rolling luggage is provided. The article has a retractable or collapsible handle that is convertible between a stored position and a first extended position of use. The handle is also rotatable about an axis such that the handle can be converted between a second extended position of use. The second extended position of use is characterized in that the luggage item may be provided such that a base portion of the item is substantially adjacent to and parallel with a ground surface. Various locking means to enable conversion between the stored position, first extended position of use and second extended position of use are also provided.
