Claim 1
Independent Claim
298 words
A one-piece injection moulded plastic suitcase frame of generally rectangular shape comprising (a) a relatively wide and substantially flat base portion, (b) two radiused lower corner portions at the ends of the base portion, said corner portions being of substantially the same width as the width of the base portion at the junctures with the base portion, one of said corner portions having said same width over a major portion of the length of the corner portion and having bushings provided on opposite sides thereof, said bushings being integrally formed with the frame and having a transverse rib extending therebetween, said bushings and rib providing means to rigidify the corner for the purpose of supporting the weight of the suitcase, (c) two relatively narrow opposite said flat portions connected to said corner portions respectively, (d) a relatively wide top portion having a width less than the base portion but wider than the side portions, (e) two radiused upper corner portions connected to the upper ends of the side portions respectively and to the ends of the top portion respectively, said corner portions being substantially the same width as the width of the top portion at the junctures with the top portion, at least one of said upper corner portions having a width substantially equal to the width of the top portion over a major portion of the length of the upper corner portion, and (f) a substantially continuous groove being provided on the outsides of the base portion, lower corner portions, side portions, top portion and upper corner portions, said groove being defined by a relatively narrow central strip offset inwardly of each of said top, base, side, upper and lower corner portions thus defining a rib on the inside surfaces of said portions complementary to said groove.
