A compression-expansion device for an article of luggage and luggage comprising same is disclosed. In one embodiment, the device comprises a base comprising axially-disposed, spaced-apart, parallel passageways; a latch pivotably disposed on the base between the passageways and having a tongue projection; an expansion body comprising conduit members slidably mated to the passageways, bias members located within the passageways and conduit members which urge the expansion body and base away from each other; an opening in the expansion body configured to receive the tongue in a first compressed position; and a button engaged with the opening and moveable to contact the tongue and displace it from the first position to a second position whereby the expansion body and the base assume an expanded configuration as urged by the bias members.

A bag for electronic devices, characterised in that it comprises a pair of facing rectangular flaps, which are provided with respective appendixes, having a semi-cylindrical profile, at one end of their long side, and with a couple of cylindrical hinges arranged in the proximity of said long side of the flap at the other end, in the inner surface, an arm 8 being fixed to each said cylindrical hinges, said arm 8 being connected to a frame through a central pivot, both being arranged on the edge of the short side of said bag.

An expandable frame (15, 115) for a carrying article is disclosed. A frame (15) for an expandable article of luggage (10) includes a first frame member (16) including a first recess (54), a second frame member (16) including a second recess (64), and a gusset (22) extending between the first frame member (16) and the second frame member (18) to secure the first frame member (16) to the second frame member (18). A first edge (40) of the gusset (22) is received in the first recess (54) in the first frame member, and a second edge (60) of the gusset (22) is received in the second recess (64) in the second frame member (18). An article of luggage (10) including the expandable frame (15) is disclosed. In some embodiments, an expandable frame (115) does not include the first frame member and the gusset (122) is secured directly to a first hard shell (112) of an article of hard shell luggage (110).

The techniques described herein relate to an expansion mechanism for an article of luggage. The article of luggage may include a rear housing portion defining a rear storage area that can be increased when the expansion mechanism is in an expanded state. A gusset may couple portions of the rear housing portion together and can be slack or taut. A first and second piece of the expansion mechanism may be mounted to the portions of the rear housing portion, respectively. When the pieces of the expansion mechanism separate in an expanded state, the gusset may also expand to a taut state. The rear storage area can be increased when the expansion mechanism is in an expanded state. The expansion mechanism may freely slide from a closed state to an open or expanded state.

A piece of luggage may include a front side, a rear side, a top side, a bottom side, a right side and a left side that define an enclosed space. The enclosed space may be divided into one or more compartments. The luggage may further include at least one zipper to access the enclosed space. The at least one zipper may include a zipper track, at least one zipper slider, and at least on zipper tab. At least a portion of the zipper track may be positioned within one or more recessed areas defined by at least some of the sides of the luggage. In some embodiments, the zipper track may be positioned within the one or more recessed areas along substantially the entire length of the zipper track.

A motorcycle case includes an inner case part which is fastenable to a motorcycle and an outer case part connected to the inner case part that is displaceable laterally relative to the inner case part. A driven gearwheel mechanism couples the inner case part and the outer case part where a width of the motorcycle case is adjustable by displacing the outer case part relative to the inner case part. The gearwheel mechanism includes at least a first gearwheel group and a second gearwheel group which each have a plurality of gears coupled to one another, rotating together and assigned to an axis of rotation, where respective teeth of adjacent gearwheel groups mesh. The first gearwheel group and the second gearwheel group each have at least one spur gear and at least one bevel gear and either the spur gears or the bevel gears of adjacent gearwheel groups mesh.

Provided are an expandable container, an expandable frame assembly, and associated components and methods. The expandable frame assembly for an expandable container may expand in at least two dimensions. The assembly may include a plurality of frame members configured to move relative to each other, a plurality of sizing members, and an adjustment mechanism operably coupled to the plurality of sizing members. Each of the plurality of sizing members may be connected to at least one of the plurality of frame members. The adjustment mechanism may be configured to move the plurality of sizing members between a first configuration and a second configuration. The first configuration may define a different distance between the plurality of frame members than the second configuration.
