Abstract
There is described a rolling bag (B) comprising a collapsible container body (10) made of an assembly of fabric panels that are joined together to form at least a bottom side (15) and a sidewall (11-14) including four lateral sides (11, 12, 13, 14) that jointly define an inner storage volume when the collapsible container body (10) takes an expanded state. The rolling bag (B) further comprises a removable rolling support assembly (S) to provide rolling support for the collapsible container body (10) in the expanded state, the rolling support assembly (S) including a support plate (P) and a plurality of caster wheels (W) provided on an underside of the support plate (P). Each caster wheel (W) includes a click-in caster wheel assembly (100) comprising a swivel axis (100A) extending at least partly through a thickness of the support plate (P), and the support plate (P) includes a plurality of supporting inserts (200) that are each configured to cooperate with the swivel axis (100A) of a corresponding one of the click-in caster wheel assemblies (100) and cause it to automatically latch onto the support plate (P) during assembly. Each supporting insert (200) comprises a mounting aperture (200A) shaped and dimensioned to receive the swivel axis (100A) and cause latching of the swivel axis (100A) inside the mounting aperture (200A).
