Sports bag with protective ribs

A bag for carrying sports equipment comprising:

• an upper wall, a bottom wall, and a side panel extending between the upper wall and bottom wall to form an enclosure for containing the sports equipment, wherein the upper wall is removably coupled to the side panel along at least a part of its perimeter to provide access to the enclosure;
• and
• a first strengthening rib comprising a first rib section extending across the upper wall, a second non-foldable rib section extending across the side panel on a first side of the bag, a third non-foldable rib section extending laterally across the bottom wall, and a fourth non-foldable rib section extending across the side panel on a second side of the bag opposite the first side, wherein the rib sections are arranged to abut each other such that they completely surround the enclosure,
• wherein the side panel comprises two side walls, a front wall, and a rear wall, and wherein the bag comprises a first pair of diagonal folds adjacent the front wall of the bag and extending across the side panel from the bottom wall to the upper wall on either side of the bag, a second pair of diagonal folds adjacent the rear wall of the bag and extending across the side panel from the bottom wall to the upper wall on either side of the bag such that the side panel folds along the first and second pairs of diagonal folds to compress the front and rear walls of the bag down flat, the upper wall is coupled to the side panel via a hinged region at a front or a rear end of the bag, and wherein the bag can be opened by flipping the upper wall outwards about the hinged region, and the bag is convertible from an assembled configuration wherein the upper wall, bottom wall, and side panel form the enclosure, to a compact configuration by opening the upper wall out at the hinged region and rolling the upper wall up from a free end towards the hinged region, collapsing the side walls of the bag inwards, compressing the front and rear end walls of the bag flat by folding the side panel along the first and second pairs of diagonal folds, and rolling the bottom wall and side walls around the upper wall.
