The present disclosure concerns a coupling mechanism for detachably attaching two or more utility modules to one another, utility assembles, mobile carriers and other attachable modules and articles.

A duffel bag can be reversibly converted to a cross-over bag by restricting the storage volume of the bag at one end. Optionally, a carrying strap may be adjusted from a central anchor to an outer anchor to facilitate draping the carrying strap over a shoulder.

An expandable luggage includes a compartment and a cover. The cover is swingly attached to the compartment to close and open the compartment. The compartment includes a bottom surface and a peripheral wall vertically extending from a periphery of the bottom surface, defining the compartment with a closable opening. Further, the cover includes a top surface and a protrusion vertically extending from a periphery of the top surface so that the protrusion coordinates with the compartment when the cover closes the closable opening. The expandable luggage includes a horizontally expandable gusseted arrangement configured along the entire peripheral wall of the compartment to horizontally expand a size of the compartment from all sides thereof and accessible from the closable opening.

A collapsible suitcase includes a main body having a rigid back panel, top, bottom, front, and rear panels. A frame is connected to the panels opposite to the back panel, and a cover is connected to one side of the frame. A liner bag is removably positioned within the main body. The main body transitions between an expanded configuration and a collapsed configuration. In the expanded configuration, the top, bottom, front, and rear panels extend orthogonal to the back panel. In the collapsed configuration the top, bottom, front and rear panels are folded inward and are positioned within the interior space of the main body. A folding wheelbase having a plurality of casters is hingedly connected to rigid back panel. In the open position the casters extend outward from the bottom panel, and in the closed position the casters are positioned against the back panel.

The present invention relates to designing a shopping bag that enhances the consumer's experience while shopping. The shopping bag can be folded and fastened using a pair of buttons and bungee bands. Further, the shopping bag can be attached with a reusable wristlet pouch that can store shopping related items such as cards, coupons, cash, wallet or the like. The consumer can either use the shopping bag along with the wristlet pouch or the wristlet pouch individually. Further, the size of the wristlet pouch or the shopping bag can be altered as required by folding the pouch or the shopping bag to the required size and fastening the folded pouch or the shopping bag by using a plurality of buttons and bungee band. Further, the shopping bag and/or the wristlet pouch can be carried by using the handles provided on the shopping bag/wristlet pouch.

The article of luggage includes a luggage main body having a bottom surface and a cavity formed to receive articles for packing; an expansion body having a perimeter defining a cavity; a foldable gusset joining the luggage main body to the expansion body; and an expansion and locking device disposed internally at opposite ends of the article of luggage. The expansion and locking device is configured to allow free movement of the expansion body in a compression direction towards the luggage main body and configured to allow locking movement of the expansion body in an expanding direction away from the luggage main body. One expansion and locking device is preferably attached to two or more walls of the luggage. After finishing packing, the luggage is closed and the user pushes the expanding member towards the base member, ratcheting the pawl past the ratchet teeth to collapse the luggage.

A collapsible suitcase has a bottom panel, a rear panel, two side panels, and a front panel. The rear panel, side panels, and front panel are connected to the bottom panel by hinges permitting them to be rotated from a folded position against the bottom panel to a deployed position perpendicular to the bottom panel. The side hinges have a clearance sufficiently greater than the clearance of the front hinge to allow the side hinges to lie flat on the front panel when folded, and the rear hinge has a sufficiently greater clearance than that of the side hinges to allow the rear panel to lie flat on the side panels when folded.

A clasp including a protrusion portion with a protrusion, and a receiving portion defining a receiving cavity configured to receive the protrusion portion is described. The protrusion is securable in the cavity via frictional fitting of the protrusion into the cavity. The frictional fitting of the protrusion into the cavity creates a secure association between the receiving portion and the protrusion portion, and the receiving portion includes a first arm and a second arm extending from a receiving portion base. The first arm includes a first arcuate recess and the second arm includes a second arcuate recess opposing the first arcuate recess, and the first arcuate recess and the second arcuate recess define adjustable width of the cavity.

A collapsible liner for use in a canister of a medical fluid collection system is disclosed. The liner includes a flexible bag extending longitudinally between a top portion opposite a closed bottom portion, and at least one support element connected to the bag and disposed generally laterally relative to a length of the bag. When an interior of the bag is subjected to a vacuum, the at least one support element limits an extent of lateral collapse while permitting longitudinal collapse. The canister includes a second vacuum source port located remotely from the lid so as to subject a space between the collapsible liner and the canister to a second vacuum commensurate to the vacuum applied to the interior of the bag.

The disclosure provides a transportation bag particularly suitable for carrying articles that can be rolled-up such as yoga-pilates mats, elongated articles such as instruments, toys, or bottles as well as, blueprints or garments such as suits or shirts. The bag may be used as a foam roller when not being used for transportation. The disclosure further relates to methods of storing, packing, and displaying rolled yoga mats and garments.
