Abstract: A piece of luggage (1) comprising a housing (2) and at least one pair of caster wheels (9), wherein each of the caster wheels (9) comprises a swivel axis (S) and at least one wheel (10) with a peripheral surface (11) rotating around a rotation axis (R) running perpendicular to the swivel axis (S). The diameter (D) of the at least one wheel (9) is as large as possible under the provision that in a rotational position parts of the peripheral surface (10) of the wheel (9) extend in a space between a center plane (C) extending centrally between a front wall (3) and a back wall (4) and a reference plane (P) extending parallel and at a distance (A) to the center plane (C), which distance (A) amounts up to 20% of the diameter (D) of the wheel (9).

Abstract: Closure device assembly (1) for a piece of luggage (5) with a zipper (60), the assembly (1) comprising a zipper slider (15) for said zipper (60), an engagement element (10) for arrangement on a first body portion (51), a buckle element (11) for arrangement on a second body portion (52) and pivotable for engagement with said engagement element (10). The assembly (1) further comprises a bolt (12) with a bolt biasing member (130) being attached to said bolt (12). Said bolt (12) is moveable between a locking position, in which said bolt (12) engages with the zipper slider (60), the latter being in closed position, and a release position, in which said zipper slider (15) is released. The buckle element (11) is adapted to cover, when engaged to said engagement element (10), said bolt (12) and said engagement section (150) of the zipper slider (15) in said closed position.
