Abstract A trolley for attachment to the corner of a suitcase or the like, for example by means of straps comprises a support assembly which is suitably shaped to receive the suitcase and a chassis assembly including a pair of ground engaging wheels. In one form of trolley the assemblies are detachably connected together so that the chassis assembly including the wheels, can be removed while leaving the support assembly attached to the suitcase.

A trolley for attachment to a corner of a suitcase to provide a support therefore, said trolley comprising an angled support assembly shaped to receive said corner of said suitcase, means for releasably securing said support assembly to said suitcase, a chassis assembly including a pair of ground-engaging wheels, and connecting means detachably securing said chassis assembly to said support assembly, said connecting means comprising inherently resilient projection means fast with said chassis assembly and socket means cooperating with said projection means and fast with said supporting assembly, and means for preventing disengagement of said cooperating projection means and socket means when said projection means and socket menas are fully engaged in a first position with said projecting means unstressed, wherein said projection means are movabLe against said inherent resilience to a second position clear of said means for preventing disengagement and in which said projection means and socket means can be disengaged to release said chassis assembly from said support assembly, said projection means comprising two parallel, spaced-apart projecting members which extend transversely of an axis of rotation of said groundengaging wheels and which form part of a frame, and said socket means comprising a pair of correspondingly spaced-apart tubular socket members fast with said support assembly, and said means for preventing disengagement comprising a portion of said frame which is parallel with said axis of rotation of said ground engaging wheels, said frame portion being normally aligned with the ends of said socket members when said socket members and projection members are interengaged, said projection members being movable against said inherent resilience sufficiently to spring said socket members out of line with said frame portion to permit disengagement of said socket members and said projection members.
