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.

Example implementations relate to a frame to removably attach bags. For example, an apparatus includes a frame, at least one frame wheel connected to the frame, and an extender device attachable to the frame. The extender device includes a platform, at least one platform wheel connected to the platform, and a first extender connector device on the platform to removably attach the platform to the frame and to removably attach the platform to a first bag of a first size. The apparatus also includes a frame connector device on the frame to removably attach the first bag to the frame.

The disclosure herein includes an expandable luggage assembly, which expandable luggage assembly may include: an upper shell having a plurality of sidewalls; a lower shell having a plurality of sidewalls removably coupled to one more of the plurality of sidewalls of the upper shell; a shelf coupled to the upper shell; a plurality of wheels coupled to the lower shell; and two handles, each handle of the two handles comprising: a crossbar disposed above the upper shell; a first tube coupled to the crossbar and slidably coupled to the upper shell; a second tube slidably coupled to the first tube and capable of being abutted against the upper shell; a third tube slidably coupled to the second tube and coupled to the lower shell.

Extendable and retractable luggage comprises a housing including a first compartment therein for storage. The luggage also includes a module movably connected to the housing. The module includes a second compartment in communication with the first compartment of the housing. The module is configured to move within the housing in a retracted position and extend away from the housing in an extended position. The housing and the module are in an axial alignment, such that both the extended and retracted positions of the module within the housing are maintained in the axial alignment. A portion of the module and a portion of the housing overlap each other and connect together when in the extended position, and when the module is positioned within the portion of the housing, a frame at a lower end of the module is positioned against a rim of the housing to provide the retracted position.

Expandable trolley suitcase comprising a bottom container having a top opening, and a top container having a bottom opening, the top container and the bottom container being slidably coupled to each other in correspondence of the bottom opening of the first one and of the top opening of the second one, at least one locking device interacting with the bottom container and with the top container and configured to assume a release configuration, at which it allows a reciprocal sliding of the bottom container and top container, and a lock configuration, at which it prevents the reciprocal sliding of the bottom container and top container, thereby the expandable trolley suitcase is configured to assume at least two geometric configurations, at which said at least one locking device assumes the lock configuration, depending on a position assumed by one between the bottom container and the top container with respect to the other, each one of said at least two geometric configurations having a respective storage volume delimited by the bottom container and top container, said at least two geometric configurations including a minimum geometric configuration having a minimum storage volume and a maximum geometric configuration having a maximum storage volume.

A collapsible protective case for surfboards having a rigid, impact-resistant outer surface, the case including a housing and a plurality of adjoining nested sections that are selectively configurable between a collapsed, fully nested position and an extended position, the housing and including a space configured to accommodate, in the extended position, fins disposed on a rear portion of the surfboard.

A protective case for large objects including a lock housing formed from a first section and a second section, both of the sections including at least one external subsection and at least one internal subsection configured to telescope inside the external subsection; and an extension lock comprising a lock housing and a compression lock, the lock housing including a screw-threaded channel, and the compression comprising at least one screw-threaded shaft with a compressive component on the interior end and a lock handle on the exterior end, the screw-threaded shaft configured to matingly engage with the screw-threaded channel of the lock housing; the compression lock configured to descend in the lock housing and compressingly lock the internal subsection in an extended position upon locking rotation of the compression lock; and the compression lock configure to ascend in the lock housing upon unlocking rotation of the cam latch.

The technology concerns a suitcase. More particularly the disclosure is directed to a collapsible suitcase.

Collapsible household containers having a foldable wall section with shape-retaining characteristics are disclosed. In particular, collapsible laundry baskets, buckets, colanders, dish drainers, and cups are provided. The folding region may include foldable tiers of a flexible material, each tier having at least one stable, relatively expanded position and at least one stable, relatively collapsed position; and an intervening, non-folding tier composed of a different, relatively rigid material.

The disclosure herein includes an expandable luggage assembly, which expandable luggage assembly may include: an upper shell having a plurality of sidewalls; a lower shell having a plurality of sidewalls removably coupled to one more of the plurality of sidewalls of the upper shell; a shelf coupled to the upper shell; a plurality of wheels coupled to the lower shell; and two handles, each handle of the two handles comprising: a crossbar disposed above the upper shell; a first tube coupled to the crossbar and slidably coupled to the upper shell; a second tube slidably coupled to the first tube and capable of being abutted against the upper shell; a third tube slidably coupled to the second tube and coupled to the lower shell.
